Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for sand and gravel stockpiles, specifically a rotating support for dust suppression spraying in sand and gravel stockpiles. Background Technology

[0002] Due to the large amount of sand and gravel stored in the open, dust is easily generated during loading, unloading, transportation, and wind. This dust will significantly increase the concentration of particulate matter in the air, which will not only affect the surrounding air quality and endanger human health (such as causing respiratory diseases), but may also pollute and damage the surrounding ecological environment and buildings. Therefore, it is necessary to carry out dust suppression spraying. When installing atomizing nozzles, brackets are usually required to connect and fix the atomizing nozzles.

[0003] During installation, the bracket is typically mounted at a suitable height, and the nozzles are installed on the bracket. The other end of the nozzle is connected to a water pipe. The pressure from the water pumped through the pipe causes the nozzle to atomize the water, which then falls from the height to purify the airborne dust. However, in practice, sand and gravel stockpiles are usually only used during the day for loading, unloading, transportation, and processing of sand and gravel. Therefore, dust suppression spraying is often activated in conjunction with production operations. During non-use periods, the nozzles mounted on the bracket are exposed. When affected by wind, sand and dust can accumulate around the nozzles, even entering the nozzles themselves, causing them to become smaller or completely blocked. This affects the normal atomization and spraying effect of subsequent spraying. Therefore, it is essential to design a practical and protective rotating support bracket for dust suppression spraying in sand and gravel stockpiles. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating support for dust suppression spraying in sand and gravel stockpiles to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a rotating support for dust suppression spraying in a sand and gravel stockpile, including a mounting plate, two support blocks fixedly connected to the lower side of the mounting plate, an outer pipe fixedly connected to the adjacent side of the two support blocks, a water inlet pipe rotatably fitted to the inner wall of the outer pipe, an assembly ring fixedly connected to the water inlet pipe, a pressure groove opened inside the assembly ring, a pressure-bearing piston slidably fitted to the inner wall of the pressure groove, and a push rod fixedly connected to the lower end of the pressure-bearing piston;

[0006] A drain trough is provided on one side of the pressure groove, located below the pressure piston. An L-shaped tube is fixedly connected to the inner wall of the drain trough. A dust suppression component that cooperates with the L-shaped tube is fixedly connected to the lower end of the push rod. A drive mechanism that cooperates with the water inlet pipe is provided on one side of the mounting plate. A return spring is fixedly connected between the pressure groove and the pressure piston.

[0007] According to the above technical solution, the dust suppression component includes a protective groove formed on the lower side of the assembly ring, a transfer box fixedly connected to the lower end of the push rod, a lifting pipe set on the upper side of the transfer box and slidingly engaged with the L-shaped tube, and an atomizing nozzle set on the lower side of the transfer box and engaged with the protective groove.

[0008] According to the above technical solution, the drive mechanism includes a mounting box fixedly connected to one side of the mounting plate, a drive motor fixedly connected to the lower side of the inner wall of the mounting box, a drive sprocket fixedly connected to the output end of the drive motor, a driven sprocket fixedly connected to the water inlet pipe, and a chain disposed on the drive sprocket and the driven sprocket.

[0009] According to the above technical solution, two limiting plates are fixedly connected to the inner wall of the pressure groove, and the two limiting plates cooperate with the pressure-bearing piston.

[0010] According to the above technical solution, a soft pad is fixedly connected to the upper side of the mounting plate, and fixing holes are provided on both the soft pad and the upper side of the mounting plate.

[0011] According to the above technical solution, a threaded connecting pipe is provided on the lower side of the transfer box, and a connecting sleeve that is threadedly connected to the upper side of the atomizing nozzle is fixedly connected to the threaded connecting pipe.

[0012] According to the above technical solution, a flow port is provided on one side of the pressure groove, and a dustproof net is fixedly connected to the inner wall of the flow port.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model, by setting up components such as a return spring, a pressure piston, a push rod, and a dust suppression component, can achieve the following when water pressure is applied: the water pressure pushes the pressure piston downward, and the push rod drives the dust suppression component to move, causing the atomizing nozzle to extend from the protective groove and start spraying. In the non-working state, when the internal water pressure disappears, the return spring pushes the pressure piston upward, which can drive the atomizing nozzle in the dust suppression component to retract into the protective groove. This can prevent sand and debris from clogging the atomizing nozzle installed on this bracket, protect its atomizing end, ensure the subsequent atomization effect, and also extend its service life.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 The present invention provides a technical solution: a rotating support for dust suppression spraying in a sand and gravel stockpile, comprising an installation plate 1, two support blocks 2 fixedly connected to the lower side of the installation plate 1, an outer pipe 3 fixedly connected to the adjacent side of the two support blocks 2, a water inlet pipe 4 rotatably fitted to the inner wall of the outer pipe 3, the outer pipe 3 and the water inlet pipe 4 being rotatably fitted by a sealed bearing, an assembly ring 5 fixedly connected to the water inlet pipe 4, a pressure groove 6 opened inside the assembly ring 5, the water inlet pipe 4 passing through the interior of the pressure groove 6, a pressure piston 7 slidably fitted to the inner wall of the pressure groove 6, and a push rod 8 fixedly connected to the lower end of the pressure piston 7;

[0022] A drain trough 9 is provided on one side of the pressure trough 6, located below the pressure piston 7. An L-shaped tube 10 is fixedly connected to the inner wall of the drain trough 9. A dust suppression component 11 that cooperates with the L-shaped tube 10 is fixedly connected to the lower end of the push rod 8. A drive mechanism 12 that cooperates with the water inlet pipe 4 is provided on one side of the mounting plate 1. A return spring 13 is fixedly connected between the pressure trough 6 and the pressure piston 7.

[0023] Please see Figure 2The dust suppression component 11 includes a protective groove 111 formed on the lower side of the assembly ring 5, a transfer box 112 that extends to the inner wall of the protective groove 111 and is slidably connected to the lower end of the push rod 8, a lifting pipe 113 that is set on the upper side of the transfer box 112 and slidably connected to the L-shaped tube 10, and an atomizing nozzle 114 that is set on the lower side of the transfer box 112 and cooperates with the protective groove 111. The lifting pipe 113 and the L-shaped tube 10 are sealed with an "O" ring or lip seal. When water flows from the L-shaped tube 10, it will be injected into the transfer box 112 through the lifting pipe 113, and then the transfer box 112 will inject the water into the atomizing nozzle 114. The water will be atomized and sprayed out through the corresponding nozzle of the atomizing nozzle 114, so that the atomized water droplets collide with the dust in the air, agglomerate, and finally settle.

[0024] Please see Figure 1 and Figure 2 The drive mechanism 12 includes a mounting box 121 fixedly connected to one side of the mounting plate 1, a drive motor 122 fixedly connected to the lower inner wall of the mounting box 121, a drive sprocket 123 fixedly connected to the output end of the drive motor 122, a driven sprocket 124 fixedly connected to the water inlet pipe 4, and a chain 125 set on the drive sprocket 123 and the driven sprocket 124. After being powered on, the motor output shaft drives the drive sprocket 123 to rotate. The drive sprocket 123 is connected to the driven sprocket 124 through the chain 125 to form a chain drive system. Since the driven sprocket 124 is directly fixed to the water inlet pipe 4, when the drive sprocket 123 rotates, the chain 125 will drive the driven sprocket 124 to rotate synchronously, thereby making the water inlet pipe 4 perform circumferential motion under the support of the outer pipe 3, and finally realize the rotation of the nozzle assembly installed on this bracket to spray.

[0025] Please see Figure 2 Two limiting plates 20 are fixedly connected to the inner wall of the pressure groove 6. The two limiting plates 20 cooperate with the pressure piston 7. When the pressure piston 7 moves downward, the limiting plates 20 can limit the pressure piston 7 to the maximum extent.

[0026] Please see Figure 1 and Figure 2 A soft pad 14 is fixedly connected to the upper side of the mounting plate 1. The soft pad 14 can be made of materials with certain elasticity and flexibility, such as rubber or polyurethane. Fixing holes 15 are provided on the upper side of both the soft pad 14 and the mounting plate 1. When the soft pad 14 contacts the mounting base (such as a roof, bracket fixing platform, etc.), the friction of its surface is large, which helps to enhance the stability of the entire device after installation and prevent it from shifting during use. The fixing holes 15 are for easy installation of the entire device in the designated position by connecting parts such as bolts and expansion bolts.

[0027] Please see Figure 2The lower side of the transfer box 112 is provided with a threaded connecting pipe 16, and the upper side of the atomizing nozzle 114 is fixedly connected with a connecting sleeve 17 that is threadedly engaged with the threaded connecting pipe 16. During installation, the operator only needs to align the connecting sleeve 17 of the atomizing nozzle 114 with the threaded connecting pipe 16 and rotate it to achieve connection. When it is necessary to replace or clean the atomizing nozzle 114, it can be disassembled by rotating it, which improves the convenience of subsequent maintenance. The threaded connecting pipe 16 and the connecting sleeve 17 are sealed threaded connections.

[0028] Please see Figure 1 A flow port 18 is provided on one side of the pressure groove 6. A dustproof net 19 is fixedly connected to the inner wall of the flow port 18. The main function of the flow port 18 is to provide a flow channel for the air in the pressure groove 6, so that the pressure of the pressurized piston 7 is normal when it flows inside the pressure groove 6. The dustproof net 19 facilitates the filtration of the air flowing through the flow port 18.

[0029] The implementation principle of this application is as follows: When in use, firstly, the mounting plate 1 is installed at a high position, and then the external pipe 3 is connected to the corresponding water supply pipe. The drive motor 122 inside the mounting box 121 is started to drive the active sprocket 123 to rotate, and the chain 125 drives the driven sprocket 124 to rotate, thereby driving the assembly ring 5 to rotate and improving the uniformity during the spraying process.

[0030] When water is injected into the external pipe 3, the water pressure pushes the pressure piston 7 downward, compressing the return spring 13. The push rod 8 then descends, and the limiting plate 20 limits the maximum stroke of the pressure piston 7 until the drain tank 9 is exposed. This allows water to flow from the inside of the drain tank 9, then through the L-shaped pipe 10 and the transfer box 112, and finally out through the atomizing nozzle 114 to form a water mist that adsorbs dust in the air. After use, when no more water is injected, the pressure disappears, the return spring 13 pushes the pressure piston 7 upward, and the atomizing nozzle 114 retracts into the protective groove 111. This allows the atomizing nozzle 114 to be retracted when not in use, preventing dust and debris from clogging it and extending its service life.
