Description

Technical Field

[0001] This utility model relates to the field of dust suppression spraying technology, and in particular to a dust suppression spraying device for atmospheric environmental protection. Background Technology

[0002] Air pollution control spray dust suppression equipment is an environmental protection device that uses high-pressure atomization technology to convert water or other liquids into micron-sized droplets, which adsorb and settle dust particles in the air, thereby achieving efficient dust suppression. This type of equipment can be widely used in industrial workshops, construction sites, mines and urban roads. Through the collision and adsorption of water mist and dust, it can effectively reduce dust concentration by more than 90%.

[0003] The atomizing nozzles of dust suppression spraying equipment pressurize water through a high-pressure pump and atomize it into micron-sized particles. As a result, the water flow rate inside the nozzle is relatively large. The internal flow channels and spray holes of the nozzle are prone to blockage due to water impurities and dust residue, leading to uneven spraying or complete failure. Especially when the water is hard or contains particulate matter, frequent cleaning is required, resulting in high maintenance costs. During cleaning, the water flow needs to be stopped, and dust suppression spraying can only be resumed after cleaning, which is inefficient.

[0004] Therefore, this application provides a dust suppression spraying device for atmospheric environmental protection to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a spray dust suppression device for atmospheric environmental protection, which solves the problems of existing spray dust suppression devices being unable to clear blocked internal spray holes during the spraying process, thus affecting the efficiency of spray dust suppression.

[0006] To solve the above technical problems, this utility model provides a dust suppression spraying device for atmospheric environmental protection, including a water inlet connected to a water tank, the water tank being connected to a spray pipe via a pump body, a nozzle fixed in the inner cavity of the spray pipe and installed in front of the axial direction of the spray pipe, and multiple spray holes evenly opened on the nozzle.

[0007] The nozzle cavity is equipped with a clearing component, which includes an inner tube that can move back and forth within the nozzle along the axial direction. The front end face of the inner tube is provided with multiple clearing needles along the axial direction. The ends of the clearing needles can be embedded in the nozzle orifice, and the clearing needles can move along the axial direction of the nozzle orifice to clear the nozzle blockage.

[0008] A further improvement of the present invention is that the unblocking component also includes a limiting plate disposed between the inner tube and the nozzle, and a spring is disposed between the limiting plate and the inner tube along the central axis direction. The spring is used to provide the restoring force of the unblocking needle. A limiting hole is opened on the limiting plate corresponding to the unblocking needle, and the unblocking needle passes through the limiting plate.

[0009] A further improvement of this utility model is that the diameter of the limiting hole and the spray hole are the same, the diameter of the unblocking needle is smaller than the diameter of the spray hole, and the end of the unblocking needle is a tapered shape that gradually tapers towards the spray hole.

[0010] A further improvement of this utility model is that flow channel holes are provided on both the inner tube and the limiting plate. The flow channel holes are used to guide the water flow around the unblocking needle. The flow channel holes on the inner tube and the unblocking needle are evenly and alternately distributed. The flow channel holes on the limiting plate and the limiting holes are evenly and alternately distributed.

[0011] A further improvement of this utility model is that control rods are symmetrically arranged radially on the inner tube sidewall, and the control rods extend out of the nozzle.

[0012] A further improvement of this utility model is that: multiple spray holes are evenly arranged in a circumferential shape, and the unblocking needles are evenly arranged in a circumferential shape.

[0013] A further improvement of this utility model is that a control groove is provided on the side wall of the nozzle to accommodate the control rod. The control groove includes an angle groove opened in the radial direction and a toggle groove opened in the axial direction. The toggle groove and the angle groove are connected. The angle between adjacent toggle grooves is 360° divided by the number of nozzles.

[0014] A further improvement of this utility model is that the number of spray holes is an integer multiple of the number of unblocking needles, and the number of actuating grooves is equal to this integer multiple.

[0015] A further improvement of this utility model is that sealing rings are respectively fitted on the inner tubes on both sides of the control rod axially, and the sealing rings abut against the inner wall of the nozzle.

[0016] A further improvement of this utility model is that the cross-sectional area of ​​the flow channel hole is larger than the cross-sectional area of ​​the spray hole.

[0017] By adopting the above technical solution, this utility model has the following beneficial effects:

[0018] 1. This utility model provides an atmospheric environmental protection spray dust suppression device. This device is beneficial for clearing blocked internal spray holes during the spraying process. The linkage design of the inner tube, clearing needle, spring and limiting plate in the clearing component allows manual control of the axial movement of the clearing needle before the spray hole is blocked. It can directly insert into the spray hole to remove the blockage and automatically reset under the action of the spring. This realizes that spraying and clearing are carried out simultaneously, avoids downtime maintenance, and significantly improves dust suppression efficiency.

[0019] 2. The present invention provides an atmospheric environmental protection spray dust suppression device with a control rod and control groove. By moving the control rod, the inner tube is rotated, and the unblocking needle switches positions at a fixed angle to accurately position multiple spray holes. During the unblocking process, it does not affect the operation of other spray holes. In each cycle, the control rod is moved in the groove in sequence to ensure that each unblocking needle periodically unblocks multiple spray holes. In each cycle, all spray holes can be unblocked.

[0020] 3. The dust suppression spraying device for atmospheric environmental protection provided by this utility model features an interlaced flow channel hole design on the inner tube and the limiting plate, which guides the water flow to evenly bypass the unblocking needle, avoiding secondary blockage of the spray holes due to water flow turbulence. The spray holes are arranged circumferentially, ensuring uniform spray coverage area. The cross-sectional area of ​​the flow channel hole is larger than that of the spray hole, reducing water flow resistance, ensuring minimal pressure loss when high-pressure water flows through, and increasing the spraying distance.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The present invention will be further explained below with reference to specific embodiments.

[0034] like Figures 1-7As shown in the figure, this embodiment provides an atmospheric environmental protection spray dust suppression device, including a water inlet 1, which is connected to a water tank 2. The water tank 2 is connected to a spray pipe 4 via a pump body 3. The direct connection design between the pump body 3 and the spray pipe 4 ensures stable water flow pressure. A nozzle 5 is fixed in the inner cavity of the spray pipe 4 and installed in front of the axial direction of the spray pipe 4. Nine spray holes 6 are evenly opened on the nozzle 5, and the nine spray holes 6 are evenly arranged in a circumferential shape to expand the dust suppression coverage area. A clearing component 7 is provided in the inner cavity of the spray pipe 4. The clearing component 7 includes an inner tube 71, which can move back and forth in the spray pipe 4 along the axial direction. Three clearing needles 72 are arranged axially on the front end face of the inner tube 71. The ends of the clearing needles 72 can be embedded in the spray holes 6, and the clearing needles 72 can move axially along the spray holes 6 to clear the blockage of the spray holes 6.

[0035] like Figures 6-7 As shown, in this embodiment, the unblocking assembly 7 further includes a limiting piece 73 disposed between the inner tube 71 and the nozzle 5. A spring 74 is disposed between the limiting piece 73 and the inner tube 71 along the central axis. The spring 74 is used to provide the restoring force of the unblocking needle 72. A limiting hole 75 is opened on the limiting piece 73 corresponding to the unblocking needle 72, and the unblocking needle 72 passes through the limiting piece 73. The diameter of the limiting hole 75 is the same as that of the nozzle 6. The diameter of the unblocking needle 72 is smaller than that of the nozzle 6 by 3~6mm. The end of the unblocking needle 72 is tapered and gradually tapers towards the nozzle 6, which can accurately penetrate the blockage and expand the unblocking range. Both the inner tube 71 and the limiting plate 73 have flow channel holes 76. The flow channel holes 76 are used to guide the water flow around the unblocking needle 72. The flow channel holes 76 and the unblocking needle 72 on the inner tube 71 are evenly and alternately distributed. The flow channel holes 76 and the limiting holes 75 on the limiting plate 73 are evenly and alternately distributed. The water flow is guided around the unblocking needle 72 and evenly distributed to the nozzle 6 to avoid secondary blockage caused by turbulence. The cross-sectional area of ​​the flow channel hole 76 is larger than the cross-sectional area of ​​the nozzle 6, which significantly reduces the water flow resistance and the pressure loss is small.

[0036] like Figures 1-2 , Figures 6-7As shown, in this embodiment, control rods 8 are symmetrically arranged radially on the sidewall of the inner tube 71, and the control rods 8 extend out of the nozzle 4. Control grooves 9 are provided on the sidewall of the nozzle 4 to accommodate the control rods 8. The control grooves 9 include radially opening angle grooves 91 and axially opening actuating grooves 92. The actuating grooves 92 and angle grooves 91 are connected. The angle between adjacent actuating grooves 92 is 360° divided by the number of nozzle holes 6. In this embodiment, the angle between adjacent actuating grooves 92 is 40°. The number of nozzle holes 6 is an integer multiple of the number of unclogging needles 72. In this embodiment, the number of nozzle holes 6 is 3 times the number of unclogging needles 72. The number of actuating grooves 92 is equal to this integer multiple, and the number of actuating grooves 92 is 3. By rotating the control rods 8, the position of the actuating grooves 92 is switched, causing the unclogging needles 72 to periodically cover all nozzle holes 6 at a fixed angle of 40°. Specifically, each actuation clears 3 nozzle holes 6, and 3 actuations clear all 9 nozzle holes 6. Sealing rings 10 are respectively fitted on the inner tubes 71 on both sides of the control rod 8. The sealing rings 10 abut against the inner wall of the spray pipe 4 to prevent high-pressure water leakage and extend the service life of the equipment.

[0037] The working principle of the technical solution provided by this utility model is as follows:

[0038] The operator opens the control valve, pressurizes the water flow through the pump body 3, and sends it into the nozzle 4. The water is then evenly distributed through the flow channel 76 to the nozzles 6, covering the target area. If impurities or dirt in the water clog individual nozzles 6, the operator pulls the control lever 8 outwards, inserting the unblocking needle 72 into the clogged nozzle 6 to remove the foreign matter. Rotating the control lever 8 to the next actuation slot 92 position switches the unblocking needle 72 to the adjacent nozzle 6. Each cycle of operation covers all nozzles 6, avoiding downtime for maintenance. Releasing the control lever 8 pushes the inner tube 71 back to its original position, and the sealing ring 10 ensures stable pressure within the nozzle 4, preventing high-pressure water leakage.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
