Description

A manufacturing system for glass particles

Technical field

The present invention relates to the technical field of glass particles, and in particular to a manufacturing system for glass particles.

Background technique

The main advantage of glass is that it has high strength, hardness, elasticity, and rigidity. Its strength and hardness are higher than those of existing general crystalline metals. It has extremely strong corrosion resistance. It also has good soft magnetic properties, making it Machinery, communications, aerospace, medicine and other fields have wide application potential. In order to obtain granular glass particles, some existing glass materials mostly use preparation equipment with a crucible on the top and a collector on the bottom. The top crucible is equipped with a heating device. , which is responsible for melting the injected glass raw material and discharging the droplets from the bottom by vibrating the transmission rod. Before discharging, inert gas is introduced into the crucible through the crucible inlet pipe to stabilize the relationship between the crucible and the vacuum chamber. The differential pressure is 30kPa. Use a signal generator to edit the pulse signal and apply it to the piezoelectric ceramics. Driven by the pulse signal, the piezoelectric ceramics generates a slight displacement and drives the transmission rod to move. This tiny displacement is acted on the melt at the bottom of the crucible by the transmission rod. , so that tiny droplets are ejected from the small holes to form droplets, and then these droplets are collected uniformly by the collector at the bottom. Patents similar to the above-mentioned prior art, such as Chinese patent application number CN201410346244.5, disclose a method and device for preparing metallic glass particles, which discloses the above-mentioned crucible with heating function and discharging function.

However, in actual production, we found that when the high-temperature melted glass droplets are directly injected into the collector for traditional collection, they cannot be rapidly cooled during the blanking process. As a result, firstly, the droplets will be formed. Secondly, it will cause the droplets falling behind to adhere to the droplets falling in front because they are in a plastic state. If refrigerant gas or cooling liquid is then introduced into the collector to cool them and separate them, they will As a result, their surface quality cannot be treated in a standardized manner, which affects product quality when used on carrier products.

Referring to Figures 1-6, a glass particle manufacturing system includes a base 1 and a crucible 2 connected to the top of the base 1 for making glass droplets. The bottom of the crucible 2 is connected to a crucible 2 for making glass droplets. The quartz glass tube 3 dripping down, the crucible 2 contains a metal melt and is provided with a heating device for heating the metal melt. The heating device includes a heater 18 surrounding the periphery of the crucible 2, installed at the bottom of the crucible 2 and facing The ceramic plate 19 below the transmission rod, and the small hole 20 opened on the ceramic plate 19 for dropping heated glass droplets along the quartz glass tube 3 into the guide rail 6 (the above structure of the crucible 2 has been disclosed , refer to the reference document CN201410346244.5, which will not be described again. The focus of the present invention is that the quality of the glass particles can be improved through the base 1).

The base 1 is provided with a cooling cabin 4 containing coolant inside. The cooling pump 28 and the cooling pipe 27 are used to circulate the coolant (circulating cooling is an existing technology and will not be described in detail). The top of the cooling cabin 4 is provided with The cover plate 5 is provided with a drop hole 51 that communicates with the inner cavity of the cooling cabin 4. The guide track 6 is installed on the top surface of the cover plate 5 and is a guide cavity structure with two spiral structures. One end of the guide track 6 is provided with a receiving end 7 that rotates inward to be close to the drop hole 51, and the other end of the guide track 6 is provided with a receiving end 8 that is rotated outward to be close to the outer wall of the cover plate 5. Now In the prior art, the quartz glass tube 3 installed on the crucible 2 is vertically downward and above the material receiving end 8, so that the glass liquid dripping downward from the quartz glass tube 3 falls into the material receiving end 8. Due to the material guide A carrier plate 9 is installed at the end of the material receiving end 8 of the track 6, and a cylinder 10 is installed on the carrier plate 9, and the operating rod of the cylinder 10 passes through the carrier plate 9 and extends into the material receiving end 8, and due to the material receiving end A hinge seat 11 is fixed on the inner ring wall of the end 8, and the hinge seat 11 is movably connected with a push plate 12 corresponding to the action rod of the cylinder 10, and several downward depressions are provided on the upper surface of the cover plate 5 Therefore, it can be seen that the droplets falling from the quartz glass tube 3 will fall into these spherical shallow grooves 13 and stay temporarily, because these spherical shallow grooves 13 correspond to the material receiving end of the guide track 6 8 and close to the push plate 12, so when the action rod of the cylinder 10 is working, its action rod will not only drive the push plate 12 to rotate in the direction of the spherical shallow groove 13, but also will rotate the push plate 12 at the moment of its rotation. The droplets falling in the spherical shallow groove 13 are pushed outward, and the impact effect produced by the moment of rotation is used to force the droplets to follow the guide track 6 and fall from the drop hole 51 into the cooling cabin 4 at the bottom. It is completely cooled and formed, so the spherical shallow groove 13 is still facing the bottom of the quartz glass tube 3. However, as we all know, the droplets are caused by high-temperature melting in the crucible 2 and are discharged through the small hole 20 (the discharge method is the current method disclosed in the reference document). technology) is a semi-fluid droplet, which still has certain plastic properties when it falls in the spherical shallow groove 13. At this time, when the push plate 12 directly pushes it outward from the spherical shallow groove 13, it is likely to cause it to adhere. It is also very likely that the push plate 12 will be plastically deformed directly. Therefore, in order to prevent this phenomenon from happening, in the present invention, as shown in Figures 5 and 6, there are also openings on the bottom surface of the cover plate 5. There are several cooling holes 14 that open downward and face the cooling cabins 4 . The cooling cabins 4 correspond to the bottoms of the spherical shallow grooves 13 , and there are openings between the cooling cabins 4 and the spherical shallow grooves 13 for connecting the two. There is an inlet hole 15 that connects up and down. A water pump 16 is installed in the cooling cabin 4. The water inlet pipe of the water pump 16 is located in the cooling cabin 4. The outlet pipe of the water pump 16 is directly below the cooling hole 14 and is used to extract the part in the cooling cabin 4. The coolant is sprayed onto the cooling holes 14, and then the coolant leaks upward into the spherical shallow groove 13 through the penetration hole 15, thereby forcing the droplets smaller than the outline size of the spherical shallow groove 13 to be pre-cooled so as not to be followed. When the push plate 12 pushes it to move, it will cause plastic deformation. The pre-cooled droplets will have a certain hardness and will not undergo significant deformation when pushed by the push plate 12, and the top of the guide rail 6 A sealing plate 24 for covering the inner cavity is fixed on the surface. When the droplets are turned into particles after pre-cooling and roll down into the cooling cabin 4 along the guide track 6, the sealing plate 24 covers the guide track 6. without causing the pre-cooled particles to jump out of the guide track 6 , and the multiple droplets that fall into the spherical shallow groove 13 at one time are pre-cooled and then move along the guide track 6 to the cooling cabin 4 They will not stick to each other when rolled down over a longer distance.

As shown in Figure 2: the cover plate 5 is provided with a seepage hole 17 away from the spherical shallow groove 13, so that the coolant sprayed from the bottom into the spherical shallow groove 13 will eventually leak from the seepage hole 17 into the cooling cabin 4 .

As shown in Figures 2 and 5: the guide track 6 includes an outer ring portion 21 located at the outermost side along its vortex profile from the material receiving end 8 and an inner portion along its vortex portion profile until it bends to the material receiving end 7 The ring part 22, the push plate 12 and the carrier plate 9 are connected with a tension spring 23 for making the push plate 12 push the particles and return again when the action rod of the cylinder 10 retracts. The push plate 12 is close to the hinge seat 11 A spring plate 25 is installed at one end. The spring plate 25 extends along the inner wall surfaces of the outer ring part 21 and the inner ring part 22 to the middle of the guide rail 6. The inner wall surfaces of the outer ring part 21 and the inner ring part 22 are provided with self-joining materials. End 8 extends to the cavity 26 of the receiving end 7, and the end of the spring plate 25 gradually tilts into the cavity 26. The function of the spring plate 25 is consistent with that of the tension spring 23, both of which are used to push the push plate 12 after the particles are pushed. Utilize their elastic properties to achieve effective return.

As shown in Figure 5, a cooling pipe 27 is provided in the cooling cabin 4 of the base 1. The top nozzle of the cooling pipe 27 corresponds to below the drop hole 51, and the bottom nozzle of the cooling pipe 27 faces the bottom of the cooling cabin 4. Cooling The shape of the tube 27 is a corrugated tube bent in multiple sections from the top downward and a mesh tube made of steel mesh. The particles falling into the cooling cabin 4 from the drop hole 51 will fall into the cooling tube 27, and then Slide down the multi-section bend-shaped inner cavity of the cooling tube 27 for a long distance, and finally make them fall on the bottom of the cooling cabin 4. In this way, the falling distance of the particle products in the cooling cabin 4 is extended, so that The contact time between it and the particles that previously landed on the bilge is lengthened to ensure that they are completely cooled before they accumulate in the bilge, and for the last time they prevent them from sticking to each other and cool down completely.
