Description

The present invention relates to a dustproof liquid spraying device , and more particularly to a dustproof liquid spraying device that can easily and effectively prevent the diffusion of dust such as earth and sand.

Dust-proof nets are installed in temporary storage places for coal and sand generated at construction sites and in coal yards to prevent the stored earth and sand and coal dust from being scattered around by strong winds (for example, Patent Document 1). The smaller the mesh of the dustproof net, the better the dustproof effect. However, if the mesh is too small, excessive resistance is generated when wind is received. Thus, the strength is increased equipment required for the frame or the like for tensioning the net there is a problem that becomes bulky. Further, since fine dust passes even if the mesh is small, there is a limit to preventing the diffusion of dust at a high level using only a dustproof net.

An object of the present invention is to provide a dustproof liquid spraying device that can easily and effectively prevent the diffusion of dust and the like.

  In order to achieve the above object, a dustproof liquid spraying apparatus according to the present invention includes a nozzle connected to a liquid supply means via a hose, a horizontal frame in which the nozzle is disposed with a jet port facing upward, and the horizontal frame. A flexible tube having a gripping frame extending downward from and an engaging portion, the nozzle having the jet outlet at a tip thereof, and a thin plate-like projecting outwardly provided integrally at a rear end portion of the flexible tube. The engagement portion is detachably engaged with a tension frame that has a guide fin and stretches a dustproof net.

  Another dust-proof liquid spraying apparatus of the present invention includes a nozzle connected to the liquid supply means via a hose, a horizontal frame in which the nozzle is arranged with the jet port facing upward, and extends downward from the horizontal frame. A flexible tube having a grip frame and a leg portion provided on the grip frame, the nozzle having the jet outlet at a tip thereof, and a thin plate projecting outwardly provided integrally at a rear end portion of the flexible tube And a guide fin having a shape, and the grip frame is erected by the leg portion.

  According to the former dustproof liquid spraying apparatus of the present invention, a nozzle connected to the liquid supply means via a hose, a horizontal frame in which the nozzle is disposed with the jet port facing upward, and a lower part from the horizontal frame Since the gripping frame that extends to and the engaging portion is provided, the nozzle can be arbitrarily set by holding the gripping frame and engaging the engaging portion at an arbitrary position of the tension frame on which the dustproof net is stretched. It can be arranged at the position. Since this nozzle has a flexible tube having a jet outlet at its tip and a thin plate-like guide fin projecting outwardly provided integrally at the rear end portion of this flexible tube, the water supplied by the liquid supply means When the liquid such as the liquid is ejected from the ejection port, the liquid is sprayed while the flexible tube is swung within the intended range by the guide fins.

Therefore, even dust such as earth and sand which is about to be scattered above the dustproof net is captured by the liquid curtain.

  Also, if this dustproof liquid spraying device is placed adjacent to the dustproof net as described above, the sprayed liquid will adhere to the dustproof net, so dust such as earth and sand to be scattered is simply put on the dustproof net. Not only is it captured, but it is also captured by the liquid adhering to the dustproof net. In this way, diffusion of dust such as earth and sand can be easily and effectively prevented.

  According to the latter dust-proof liquid spraying device of the present invention, instead of the engaging part of the former dust-proof liquid spraying device, since the leg portion provided on the grip frame is provided, the gripping frame is moved. Thus, the nozzle can be arranged at an arbitrary position regardless of the presence / absence of the dust-proof net tension frame only by erecting the grip frame by the leg portion at an arbitrary position. Therefore, a liquid curtain can be formed at an arbitrary position by the liquid sprayed from the nozzle outlet.

  In addition, if this dust-proof liquid spraying device is placed adjacent to the dust-proof net, the sprayed liquid will adhere to the dust-proof net, so dust such as earth and sand to be scattered can simply be captured by the dust-proof net. Without being caught by the liquid adhering to the dust-proof net. In this way, diffusion of dust such as earth and sand can be easily and effectively prevented.

The embodiment of the dustproof liquid spraying apparatus 1 of the present invention illustrated in FIGS. 1 and 2 is detachably attached to a tension frame 13 that stretches a dustproof net 12. The tension frame 13 includes, for example, a vertical frame 13a extending in the vertical direction, a horizontal frame 13b extending in the horizontal direction, and a support frame 13c that supports the vertical frame 13a and the horizontal frame 13b, and the dustproof net 12 is stretched. . The height at which the vertical frame 13a protrudes on the ground, that is, the height of the tension frame 13 is, for example, about 2 m to 4 m. The dustproof unit 14 includes a dustproof liquid spraying device 1 and a dustproof net 12 disposed adjacent to the dustproof liquid spraying device 1.

  The dustproof net 12 has a generally used specification. For example, synthetic dust fibers such as polyester fibers and polyethylene fibers, natural fibers, and the like are formed in a lattice shape. The fibers forming the dustproof net 12 are made of a material that adheres moisture. The side length of the lattice-like mesh is, for example, about 1 mm to 10 mm.

  The dust-proof liquid spraying apparatus 1 includes a nozzle 2 connected to a liquid supply means 10 via a hose 9, a horizontal frame 5 on which the nozzle 2 is disposed, and a gripping frame 6 extending downward from the horizontal frame 5. And an engaging portion 5a detachably engaged with the tension frame 13.

  The horizontal frame 5 and the grip frame 6 are preferably formed of a light metal such as aluminum or a hard resin for weight reduction. The engaging portion 5 a protruding from the horizontal frame 5 is also preferably made of the same material as the horizontal frame 5 and the gripping frame 6. The engaging portion 5 a can be provided on the horizontal frame 5 or the grip frame 6. The engaging portion 5a of this embodiment is formed in a key shape bent at a right angle, but various shapes that can be detachably engaged with the tension frame 13 (lateral frame 13b) can be adopted.

  The grip frame 6 is set to a length that extends to a position that can be gripped by the operator when the engaging portion 5a is engaged with the uppermost horizontal frame 13b. For example, the length of the grip frame 6 is about 2 m to 3 m. Alternatively, the length of the gripping frame 6 is such that when the engaging portion 5a is engaged with the uppermost horizontal frame 13b, the lower end of the gripping frame 6 is positioned at about 0.8 m to 1.2 m from the ground. Set to As the grip frame 6, for example, a round bar or a round pipe having an outer diameter of about 30 mm is used. The length of the horizontal frame 5 is, for example, about 3 m to 5 m.

  The nozzle 2 is disposed on the horizontal frame 5 with the jet port 2a facing upward, and as illustrated in FIGS. 3 and 4, the flexible tube 3 having the jet port 2a at the tip, and the rear end portion of the flexible tube 3 And a thin plate-like guide fin 4 provided integrally therewith. The flexible tube 3 and the guide fin 4 are made of a soft resin, rubber, or the like and are very flexible. The inner diameter of the flexible tube 3 and the outlet 2a is, for example, about 0.2 mm to 3 mm. In consideration of durability and the like, the flexible tube 3 and the guide fin 4 are preferably formed of silicon rubber. Although the number of nozzles 2 is not particularly limited, for example, they are arranged on the horizontal frame 5 with an interval of about 1.5 m to 2.0 m.

  The outer diameter of the flexible tube 3 is, for example, about 0.5 mm to 5 mm. The guide fins 4 project outward from the flexible tube 3. The extending direction of the guide fins 4 is set to a direction orthogonal to the extending direction of the horizontal frame 5.

  The thickness of the guide fin 4 is, for example, about 2 mm to 6 mm. The guide fins 4 of this embodiment have a substantially triangular shape that tapers toward the ejection port 2a, and two guide fins 4 are provided symmetrically about the flexible tube 3. The shape of the guide fins 4 may be other shapes such as a rectangle.

  The tips of the guide fins 4 are located at the center of the length of the flexible tube 3 (in the range of about 40% to 60% of the length).

  A rigid thin tube 7 is inserted and attached to the rear end of the flexible tube 3. The rear end portion of the thin tube 7 is connected to one end portion of the hose 9 via a joint 8. The narrow tube 7 or the joint 8 is fixed to the horizontal frame 5, and the nozzle 2 is indirectly fixed to the horizontal frame 5.

  A pump is used as the liquid supply means 10. The liquid supply means 10 is operated by the generator 10a. The other end of the hose 9 is connected to the liquid supply means 10 and is connected to a tank 10b that stores the liquid W through another pipe. In this embodiment, the liquid supply means 10 and the compressor 10c are mounted on a movable carriage 11.

  The compressor 10c extracts the remaining liquid in the hose 9 in winter or the like so that the remaining liquid does not freeze in the hose 9. After the operation of spraying the liquid W is completed, the hose 9 is changed from the liquid supply means 10 to the compressor 10c, and the compressor 10c is operated by the generator 10a to blow into the hose 9 and extract the remaining liquid. It is optional to provide the compressor 10c. In addition, you may make it mount the generator 10a and the tank 10b in the trolley | bogie 11. FIG.

  Next, a method for preventing dust using the dustproof liquid spraying apparatus 1 and the dustproof unit 14 will be described below.

  First, as illustrated in FIGS. 1 and 2, the engaging portion 5 a is engaged with a desired position of the uppermost horizontal frame 13 b, and the dustproof liquid spraying device 1 is placed at a desired position of the tension frame 13. Install. The operator can easily place the nozzle 2 at an appropriate place by moving the holding frame 6. In this embodiment, the engaging portion 5a can be attached to and detached from a desired position of the tension frame 13, and the nozzle 2 can be placed at an appropriate location by engaging the engagement portion 5a with the tension frame 13 and attaching it. Can be arranged.

  Next, the liquid supply means 10 is operated to supply the liquid W stored in the tank 10 b through the hose 9 to the nozzle 2. As the liquid W, water, a water-soluble chemical solution, or the like is used. As the water-soluble chemical solution, for example, a solution having a property of adhering to and solidifying with dust can be used. The supply flow rate of the liquid W is, for example, about 0.05 to 2 L / min, and the liquid pressure is, for example, about 0.2 MPa to 0.5 MPa.

  Since the flexible tube 3 and the guide fin 4 are rich in flexibility, as illustrated in FIGS. 3 and 5, the liquid W is sprayed from the jet outlet 2 a while being swung by the jet flow of the liquid W. The nozzle 2 is provided with guide fins 4, and the circumferential rigidity of the nozzle 2 is directional. Therefore, the guide fin 4 swings with a larger amplitude in the direction perpendicular to the projecting direction than the projecting direction of the guide fin 4.

  That is, in this embodiment, the nozzle 2 swings greatly in the extending direction of the horizontal frame 5. The spraying range R (sprinkling distance) of the liquid W sprayed from the jet nozzle 2a is, for example, twice or more in the extending direction of the horizontal frame 5 with respect to the direction orthogonal to the extending direction of the horizontal frame 5.

  Then, the liquid W sprayed from the nozzle 2 that continuously reciprocates and swings forms a film shape downward from a position higher than the dust-proof net 12, so to speak, forms a curtain of the liquid W. For example, the curtain of the liquid W is formed up to a position about 1 m higher than the upper end of the dustproof net 12. Therefore, dust such as earth and sand S which is going to be scattered above the dustproof net 12 is captured by the curtain of the liquid W.

  Further, the sprayed liquid W adheres to the dust net 12. Therefore, dust such as earth and sand S to be scattered is not only simply captured by the dustproof net 12 but also captured by the liquid W adhering to the dustproof net 12.

  In this way, in the present invention, the diffusion of dust such as earth and sand S can be easily and effectively prevented.

  When a water-soluble chemical liquid having a property of adhering to dust and solidifying is used as the liquid W, the water-soluble chemical liquid adhered to the dust falls on the ground in a state where the dust is entangled and caught. The water-soluble chemical that has fallen on the ground solidifies in a state where it is trapped in dust. The dust solidified on the ground by the water-soluble chemical liquid does not easily rise from the ground even when it is blown by the wind, and this is increasingly advantageous for preventing the dust from scattering.

  Each nozzle 2 is arrange | positioned in the position where the spraying range R of the adjacent nozzle 2 overlaps. Thereby, dust can be captured using the area of the dustproof net 12 to the maximum.

  If the extending direction of the guide fins 4 is set in a direction orthogonal to the extending direction of the horizontal frame 5 as in this embodiment, the sprayed liquid W can be attached to the dustproof net 12 more efficiently. .

  If the engaging portion 5 a is provided at a symmetrical position of the horizontal frame 5 with the gripping frame 6 as the center, it is advantageous to stably install the nozzle 2 by the tension frame 13.

  When watering is completed at one position, the nozzle 2 is installed at the desired position of the tension frame 13 by engaging the engaging portion 5a with the desired next position of the uppermost horizontal frame 13b in the same procedure. To do. Next, watering is performed in the same manner. This step is sequentially performed within the necessary range while changing the position.

  In this embodiment, since the liquid supply means 10 is mounted on the carriage 11, there is an advantage that the nozzle 2 can be moved smoothly.

In the reference form of the dustproof liquid spraying apparatus 1 illustrated in FIG. 6, the grip frame 6 is provided with a leg portion 6 a such as a tripod. The grip frame 6 can be erected by the leg portion 6a. In other words, the engaging portion 5a of the previous embodiment is replaced with the leg portion 6a, and the rest is the same as the previous embodiment.

In this reference form , the gripping frame 6 can be self-supported by the legs 6a, so that the nozzle 2 can be arranged at an arbitrary position without being restricted by the position of the tension frame 13. Therefore, in a site where the dust-proof net 12 cannot be stretched due to space restrictions or the like, dust scattering can be prevented only by the liquid W curtain formed by the liquid W sprayed from the nozzle 2.

  Of course, this dust-proof liquid spraying device 1 can also be disposed adjacent to the dust-proof net 12 for use. In this case, the liquid W sprayed from the nozzle 2 is made to adhere to the dustproof net 12. Moreover, it can also be set as the form provided with the leg part 6a and the engaging part 5a.

  In another embodiment of the dustproof liquid spraying apparatus 1 illustrated in FIGS. 7 and 8, a plurality of nozzles 2 are arranged adjacent to each other in the extending direction of the horizontal frame 5. The number of nozzles 2 arranged close to one place may be three, two, four or more as in this embodiment. In this embodiment, the nozzle group in which the plurality of nozzles 2 are arranged close to each other in this way is installed at three locations. One or a plurality of nozzle groups may be installed. Separate hoses 9 can be connected to the nozzles 2 of one nozzle group, and the same hose 9 can be branched and connected.

  Further, among the three nozzles arranged at one place, the respective nozzles 2 at both ends in the extending direction of the horizontal frame 5 are attached to the horizontal frame 5 via the rotary joint 2b. Thereby, these nozzles 2 are configured to be able to rotate the jet outlet 2a with the extending direction of the horizontal frame 5 as the rotation axis direction, and can be fixed at an arbitrary rotation position. The central nozzle 2 sandwiched between the nozzles 2 at both ends is non-rotatably attached to the horizontal frame 5, and the jet outlet 2a faces upward. Of the plurality of nozzles 2 arranged close to each other, at least one nozzle 2 may be rotatable as described above, and all the nozzles 2 may be rotatable as described above.

  In this embodiment, for example, at least one nozzle 2 among the nozzles 2 arranged close to each other is rotated to direct the jet outlet 2a to the windward side. Then, the remaining nozzles 2 direct the jet outlet 2a directly above. As a result, the liquid W sprayed from the jet port 2 a directed toward the windward is pushed back by the wind, and a curtain of the liquid W is formed in the vicinity of just above the horizontal frame 5. On the other hand, the liquid W sprayed from the jet port 2a directed upward is protected by the curtain of the liquid W sprayed from the jet port 2a directed upwind, and hardly flows in the wind. A curtain of liquid W is formed in the vicinity of almost directly above.

  In this embodiment, as described above, it is easy to form the curtain of the liquid W in a desired range even if there is an influence of wind. More preferably, the number of the nozzles 2 arranged close to one place is three or more, and among these nozzles, at least the nozzles 2 positioned at both ends can rotate the jet outlet 2a as described above. Make the configuration. Thereby, the curtain of the liquid W sprayed from the jet outlet 2a of the nozzle 2 located in the center is protected in a state sandwiched between the curtains of the liquid W sprayed from the jet outlet 2a of the nozzle 2 at both ends, It becomes harder to be washed away by the wind.
