The embodiment of the present application provides a mixer, as shown in Fig. 1-2, the mixer 2 is set in the dissolving device. The mixer 2 has a plurality of impellers 20, and each impeller 20 is spirally arranged around the first direction (arrow direction shown in FIG. 2 ). It should be noted that the impeller 20 is arranged in a spiral curved structure, that is to say , the rotary vane 20 is not only a smooth curved surface structure, and the rotary vane 20 has a twisted shape as a whole, so that when the mixed liquid with washing substances flows through the surface of the rotary vane 20, the mixed liquid will flow along the The surface of the rotary vane 20 performs a torsional movement, and the mixed liquid is affected by the shape of the surface of the rotary vane 20, so that the flow velocity and direction of the mixed liquid passing through each point on the surface of the rotary vane 20 are changed, and the mixed liquid is twisted with the surface structure of the rotary vane 20 During the process, a sharp inertial force will be generated, which makes the mixed liquid form turbulent flow under the action of forces in different directions, and the mixing of the liquid is relatively difficult. for full.

It should be noted that the embodiment of the present application does not limit the specific structure of the rotating vane 20 , it can be considered that the thickness of the rotating vane 20 is relatively thin and is a structure obtained by twisting a two-dimensional planar member. For example, the two ends of the rectangular thin plate in the length direction respectively apply torque in opposite directions around the length direction (for example, a clockwise torque is applied to one end, and a counterclockwise torque is applied to the other end). X-shaped structure; of course, the rotary vane 20 can also be twisted and shaped by a semicircular approximately flat piece. In other embodiments, the rotary vane 20 can also be twisted and shaped by other shapes, no matter what shape the rotary vane 20 is twisted by Forming, as long as the liquid flows along the impeller, the liquid can be twisted and the direction can be changed.

As shown in FIG. 2 and FIG. 3 , in the embodiment of the present application, the helical directions of adjacent rotating vanes 20 are opposite. For example, when the mixed liquid flows through the mixer 2, the mixed liquid moves along one of the impellers 20, then the moving direction of the mixed liquid is roughly consistent with the helical direction of the impeller 20, when the mixed liquid moves from the impeller 20 In the case of moving to the adjacent rotary vane 20, the helical direction of the adjacent rotary vane 20 changes, so that the moving direction of the mixed liquid changes, then it can be roughly considered that the moving direction of the mixed liquid in the adjacent rotary vane 20 is the same as that of the rotary vane 20. The direction of movement of the blades 20 is opposite (for example, the mixed liquid moves clockwise around the first direction in one rotary blade 20, and the mixed liquid enters the adjacent rotary blade 20 and moves counterclockwise around the first direction), and the embodiment described in the present application The opposite direction of fluid motion does not mean that the velocity direction of the fluid at each point on the adjacent rotor blades is absolutely opposite, but it can be understood that because the spiral direction of the adjacent rotor blades is opposite, the rotation direction of the fluid passing through the rotor blades is deflected The direction of rotation of the fluid appears to be opposite to that of rotation on two adjacent impellers. In some embodiments, the structure, length and shape of each vane can be different as long as the helical direction is opposite. In some other embodiments, the structures of adjacent impellers can also be exactly the same. It can be understood that if each impeller can be disassembled into independent parts, each impeller can be stacked and the stacked surfaces overlap, while the adjacent impellers in the mixer The setting of the rotary vanes is that the placement angle of the rotary vanes of the same structure is changed, which can be understood as the angle difference between the phases corresponding to the starting sides of adjacent rotary vanes. For example, as shown in Figure 3, the fluid passes through many Three rotary vanes flow to the right side, and Fig. 3 schematically shows three rotary vanes, the structure and shape of these three rotary vanes are the same, and when viewed from left to right, the starting edge (left edge) of the first rotary vane and There is an included angle between the extension directions of the starting edge (left edge) of the second rotary vane, so that, viewed from left to right, the fluid rotates counterclockwise around the left and right directions shown in Figure 3 when passing through the first rotary vane , and turn clockwise around the left and right directions shown in Figure 3 when passing through the second rotary vane. No matter what specific expression form is used for the helical directions of two adjacent rotor blades to express the opposite characteristics, as long as the mixed liquid can be twisted in the direction of motion when it passes through the adjacent rotor blades.

An embodiment of the present application provides a mixer, the mixer has a plurality of spiral blades arranged around a first direction, and the spiral directions of adjacent spiral blades are opposite. When the mixed liquid flows through the mixer, the mixed liquid moves along the helical direction of the impeller. Since the moving speed and direction of the mixed liquid at each point on the impeller are different, the mixed liquid located at the center and outer edge of the impeller can interact with each other. Collision, the helical direction of the adjacent rotating vane changes, and the mixed liquid will also be reversed and exchanged under the action of a sharp inertial force, so that the washing material can be fully mixed and dissolved with water under the action of the mixer, which improves the mixing liquid. The disturbing effect is conducive to improving the utilization rate of washing materials and reducing the amount of washing materials. And the above-mentioned forward rotation and reverse rotation when the mixed fluid passes through the rotary vane does not need to be realized by the rotation of the rotary vane.

In some embodiments, as shown in FIG. 3 , the extending directions of adjacent edges of two adjacent rotating vanes 20 are vertical. The mixer 2 in the embodiment shown in Fig. 3 is provided with a plurality of impellers in the first direction (arrow direction shown in Fig. 3 ), and what adjacent impellers 20 represent is that among the plurality of impellers 20 in the first direction The two closest rotating vanes, each rotating vane 20 has two ends in the first direction (arrow direction shown in FIG. 3 ), one end (left end shown in FIG. 3 ) is the first edge 201 of the rotating vane 20, The other end (the right end shown in FIG. 3 ) is the second edge 202 of the rotary vane 20, and the first edge of each rotary vane is adjacent to the second edge of another rotary vane, as shown in FIG. 3 . In the rotary vane, the second edge 202 of the left rotary vane is adjacent to the first edge 201 of the right rotary vane, and the extension direction of the second edge 202 of the left rotary vane (the direction indicated by the dotted line a in FIG. 3 ) and the extension direction of the first edge 201 of the right rotary vane It is perpendicular to (the direction indicated by dotted line b in Fig. 3), it should be noted that the first edge or the second edge can be regarded as a two-dimensional plane figure, so the extension direction represents the length of the first edge or the second edge Direction (that is, the dotted line a in Figure 3 represents the extension direction of the second edge of the left-hand revolving vane, that is, the direction of the maximum dimension of the second edge of the left-hand revolving vane; the dotted line b represents the first edge of the right-hand revolving vane The extending direction of the edge, that is, the direction of the largest dimension of the first edge). In the embodiment of the present application, the second edge of the adjacent rotating vane is substantially perpendicular to the first edge, including the case where the extension direction of the second edge is not strictly 90 degrees to the extension direction of the first edge, and it can be considered that the two directions are sandwiched An angle greater than 80 degrees is basically vertical, which can cover the situation of processing and installation errors. Certainly, in other embodiments, the extending directions of adjacent edges of two adjacent rotating vanes may also be arranged at an acute angle, as long as the adjacent edges intersect.

With reference to Fig. 4, the mixer in the embodiment of the present application will describe the stirring principle of the fluid as follows:

By extending the adjacent edges of two adjacent rotary vanes vertically, for example, the second edge 202 of the first rotary vane on the left in FIG. The second edge of the first rotary vane is substantially perpendicular to the first edge of the third rotary vane, when the mixed liquid flows from the first rotary vane to the second rotary vane, since the first edge 201 of the second rotary vane is The second edge 202 of the first rotary vane is vertical, and the liquid flowing to the second edge 202 of the first rotary vane will form two streams of liquid under the division of the first edge 201 of the second rotary vane. The liquid flows along the two sides of the second rotary vane respectively. The solid arrow on the left side in Fig. 4 indicates the mixed liquid flowing along the back of the first rotary vane, the dotted arrow indicates the mixed liquid flowing along the front of the first rotary vane, and the two streams of liquid flow along the first rotary vane respectively. The positive and negative sides of the rotary vane flow, when the mixed liquid (indicated by the dotted line arrow) flowing on the front side of the first rotary vane flows to the second edge 202 of the first rotary vane, the mixed liquid on the front side of the first rotary vane is absorbed by the second rotary vane. The upper part of the first edge 201 of the blade is divided into two streams of liquid, and these two streams of liquid flow respectively from the upper part along the two sides of the second rotary vane; At the second edge 202, the mixed liquid on the back of the first impeller is absorbed by the second The lower part of the first edge 201 of the first rotary vane is divided into two streams of liquid, and the two streams of liquid respectively flow from the lower part along the two sides of the second rotary vane. The four streams of liquid entering the second impeller flow along different positions of the second impeller, and the four streams of liquid can communicate with each other under the surface torsion of the second impeller, and the four streams of liquid flow to the second impeller At the time of the second edge 202, each liquid will be divided into two liquids by the first edge of the third rotating vane, and finally these four liquids will be divided into eight liquids by the third rotating vane. By vertically setting the extension direction of the adjacent edges of the adjacent rotating blades, the adjacent rotating blades will continuously divide the mixed liquid, which can enhance the efficiency of dissolving the washing material in water; and the mixed liquid will be separated under different spiral directions of the rotating blades. Change the direction of movement, so that the liquid is reversed, and the liquid will also flow from the center to the outer edge or flow from the outer edge to the center when the liquid flows through the same rotor. Under multiple actions, the washing material and The mixing effect of water is enhanced, which improves the dissolution efficiency of washing substances.

In some embodiments, as shown in FIG. 3 , each rotary vane 20 has opposite first edges 201 and second edges 202 in a first direction, and the extension direction of the first edge 201 is parallel to the extension of the second edge 202 direction. It should be noted that the parallel in the embodiment of the present application means that the angle between the extension direction of the first edge 201 and the extension direction of the second edge 202 is not strictly 0 degrees, and it can be considered that the angle between the two directions Less than 10 degrees is basically parallel, which can cover the situation of processing and installation errors. In the embodiment of the present application, the first edge of each rotary vane in the first direction is parallel to the extension direction of the second edge, so that the first edge rotates around the first direction once and translates along the first direction for a certain distance, and then can be aligned with the second edge. The two edges overlap, and the mixed liquid moves along the spiral surface formed on the impeller, so that the mixed liquid originally under the impeller can move to the top of the impeller along with the surface of the impeller, and the mixed liquid originally above the impeller can move To the bottom of the rotor, the liquid originally on the left side of the rotor can move to the right side of the rotor, and the liquid originally on the right side of the rotor can move to the left side of the rotor. The helical structure of the rotor can reverse the position of the liquid , Improve the efficiency of mixing liquid stirring.

A vortex can be formed between the liquids, and the fins can further disturb the mixed liquid, which can improve the dissolution efficiency of the washing material and water, and in the process of disturbance, the mixed liquid will generate a lot of foam when it contacts with the air, which is beneficial to improve the washing effect. Cleansing effect of mixed liquids.

In some embodiments, as shown in FIG. 6 , a plurality of fins 34 are disposed in the drainage channel 31 , and the plurality of fins 34 are arranged at equal intervals along the length extension direction and the circumferential direction of the drainage channel 31 . The length extension direction (arrow direction shown in FIG. 6 ) can be represented by the length direction of the inner wall surface 33 of the discharge pipe. The inner wall surface 33 of the discharge pipe is roughly surrounded by a hollow structure with open ends, so the circumferential direction refers to the direction around the length direction (the direction around the arrow in FIG. 6 ). That is to say, a plurality of fins 34 are arranged at intervals in each direction of the inner wall surface 33 , so as to fully disturb the mixed liquid flowing through the discharge channel.

It should be noted that the number of fins 34 in the embodiment of the present application is closely related to the radial and longitudinal dimensions of the fins, and the disturbance effect of the fins 34 on the mixed liquid is not related to that of the fins. The number of 34 has a linear growth relationship. If multiple fins are set in a discharge pipe of a certain size, as the number of fins increases, the disturbing effect of the fins on the mixed liquid may increase or decrease. Therefore, the number of fins 34 needs to be set according to the specific size of the discharge pipe.

In some embodiments, as shown in FIG. 6 , in the length direction of the drainage channel 31 (the direction of the arrow shown in FIG. 6 ), the distance L1 between adjacent fins 34 is greater than or equal to the first length and less than or equal to The second length, wherein, the first length is 0.8 times the inner diameter of the drain pipe 3 , and the second length is 1.2 times the inner diameter of the drain pipe 3 . It should be noted that, if there are multiple points on the fins 34, the distances of each point between adjacent fins 34 may be inconsistent, because one end of the fins 34 is connected with the inner wall surface 33 (this connection position can be regarded as a two-dimensional connecting line), so the distance between adjacent fins 34 described in the embodiment of the present application can be represented by the shortest distance between connecting lines of points of adjacent fins 34 . If the distance between the fins is greater than this range value, there will be a certain area between the fins so that the mixed liquid will not be disturbed; If the blocking effect is too strong, it is difficult for the mixed liquid to pass through the gap between the fins, making it difficult for the mixed liquid to form a vortex without being disturbed. In the embodiment of the present application, by setting the distance between adjacent fins in the length direction within a certain range, it is obtained through the simulation analysis of the structural parameters that the fins set within the data range will affect the mixing in the drainage channel. The disturbance effect of the liquid is better.

In some embodiments, as shown in FIG. 6 , the drain pipe 3 is provided with 3-5 fins at the same position along the length direction of the drain channel 31 (the direction indicated by the arrow shown in FIG. 6 ). Wherein, the same position can be understood as that multiple rows of fins 34 are arranged in the length direction of the liquid discharge channel 31, and each row of fins 34 is located on the same circumference, and each row is provided with a plurality of fins, so the fins on the same row The fins 34 can be considered to be located at the same position in the length direction. Through simulation analysis, it can be concluded that by arranging 3-5 fins on the discharge pipe, the disturbance effect of the discharge pipe on the mixed liquid is better. It should be noted that other numbers of fins can also be provided in other embodiments, that is to say, the number of fins can be related to the size of the drain pipe and the size of the fins.

In some embodiments adjacent fins along the length of the drainage channel are circumferentially staggered set up. That is to say, the projection intervals of two adjacent rows of fins in the length direction in the circumferential direction are staggered and do not overlap each other, and the positions of the two adjacent rows of fins in the length direction are different in the circumferential direction. In the embodiment of the present application, the agitation effect of the mixed liquid can be improved by arranging the fins in a staggered manner. It should be noted that the feature of interlaced fins is not directly proportional to the agitation effect, and the agitation effect is also related to parameters such as the number of fins, the size of the fins, and the size of the discharge pipe. The embodiments of the present application can be based on other The parameters are set to choose whether to set the feature of interlaced fins, and then a stronger disturbance effect can be obtained.

In some embodiments, as shown in FIG. 6 , the included angle θ of the tangent plane between the fin 34 and the inner wall 33 is greater than or equal to 20 degrees and less than or equal to 45 degrees, and one end of the fin 34 is connected to the inner wall 33 , The other end is a free end, and the end where the fin 34 is connected to the inner wall surface 33 is a joint, and the cut surface of the joint is perpendicular to the radial direction of the discharge pipe 3 . The fin 34 can be approximated as a two-dimensional plane, and the angle between the fin 34 and the inner wall can be approximated as the angle between the two-dimensional plane and the tangent plane of the joint, that is, the angle between two planes. The included angle θ of the tangent plane at the joint between the fin 34 and the inner wall surface 33 represents the included angle between the right side and the tangent plane of the wing 34 in FIG. 6 , rather than the included angle between the left side and the tangent plane. The distance from the fins 34 to the inner wall 33 increases as the distance from the inlet 32 of the drainage channel 31 increases. It can be understood that the distance from the fins 34 to the inner wall 33 gradually increases from left to right in FIG. 6 . In the embodiment of the present application, by setting the fins obliquely relative to the inner wall, the fins can not only disturb the mixed liquid in the drainage channel, but also prevent the mixed liquid from remaining between the fins and the inner wall.

In some embodiments, as shown in FIG. 7 , one end 341 of the fin 34 in the length direction is connected to the inner wall surface 33 , and the length direction indicates the extending direction of the fin 34 (this direction is not necessarily the direction of the largest dimension of the fin 34 ) , that is, the direction of the fin 34 from one end 341 to the other end 342, the other end 342 of the fin 34 is a free end; the width of the fin 34 gradually decreases from one end to the other end. It should be noted that the width direction of the fin 34 is perpendicular to the length direction. By setting the width of the fins to gradually decrease from one end to the other, the speed and direction of the mixed liquid flowing through each point of the fins are changed, and the mixed liquid is more likely to form turbulent flow under the condition of changing fin size. improve mix The perturbation effect of the liquid.

In some embodiments, as shown in FIG. 7, the width L3 of one end 341 of the fin 34 is greater than or equal to 0.08 times the inner diameter L2 of the drain pipe 3 and less than or equal to 0.12 times the inner diameter L2 of the drain pipe 3; Yes, when the discharge pipe 3 is set as a standard round pipe, the inner diameter of the discharge pipe 3 can be expressed by the inner diameter of the discharge pipe 3; if the discharge pipe 3 is set as a non-standard shape, the discharge pipe 3 can be The cross section of the tube 3 is transformed into a standard circular surface of equal area, and the diameter of the standard circular surface is defined as the inner diameter of the discharge pipe 3, wherein the cross section of the discharge pipe 3 is perpendicular to the length direction of the discharge pipe 3. In some embodiments, the width L4 of the other end 342 of the fin 34 is greater than or equal to 0.2 times the inner diameter L2 of the drain pipe 3 and less than or equal to 0.25 times the inner diameter L2 of the drain pipe 3; The length L5 from one end 341 to the other end 342 of the sheet 34 is greater than or equal to 0.4 times the inner diameter L2 of the drain tube 3 and less than or equal to 0.45 times the inner diameter L2 of the drain tube 3 .
