Description

Technical Field

[0001] The present invention relates to the field of dust reduction mechanisms, specifically a spray dust suppression device. Background Art

[0002] In many scenarios such as industrial production, construction, and material stacking, dust pollution is a common and urgent problem to be solved. A large amount of dust fills the air, which not only has an adverse impact on the working environment, damages the physical health of workers, and causes a series of health problems such as respiratory diseases, but also pollutes the surrounding environment and affects the ecological balance.

[0003] Traditional dust suppression methods have many limitations. For example, the manual watering dust suppression method requires a large amount of manpower and time, has low efficiency, and the watering is uneven, making it difficult to achieve an ideal dust suppression effect; some fixed spray devices have a fixed installation position and cannot flexibly adjust the spray height and range according to actual needs, and have poor adaptability to dust sources of different heights and areas; in addition, when some spray devices draw water from the water tank, due to the change in the water level in the water tank, the water pumping may be不畅, affecting the normal operation of the device, and the handling process of the device is also more laborious, increasing the use cost and operation difficulty.

[0004] Therefore, it is of great practical significance to develop a spray dust suppression device that can flexibly adjust the spray height, has an adjustable spray range, stable water pumping, and is easy to handle. Summary of the Invention

[0005] The purpose of the present invention is to provide a spray dust suppression device to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A spray dust suppression device includes a water tank. The top of the water tank is movably inserted with a lifting cylinder. The top of the lifting cylinder is installed with a tray. A pump body is installed inside the lifting cylinder. The water pumping end of the pump body penetrates the bottom plate of the lifting cylinder, and a bellows is sleeved and fixed on the water pumping end of the pump body. The bellows extends to the bottom of the water tank. The drain pipe of the pump body is inserted into the tray, and the tray sprays the water injected by the pump body through the four sides of the tray. Wear-resistant rubber rings are sleeved and fixed on both the top end and the bottom end of the water tank.

[0007] Preferably, a reserved opening is provided on the top surface of the water tank. The reserved opening is an inverted "convex" - shaped circular opening. A wire sleeve is fixed on the bottom surface of the top plate of the water tank. The inner ring surface of the wire sleeve has internal threads. The outer wall of the lifting cylinder has external threads. The external threads and the internal threads are in threaded connection. There are multiple groups of external threads, and the multiple groups of external threads are arranged in an equidistant and equal - sized manner in a vertical arrangement.

[0008] Preferably, a counterweight ball is sleeved and fixed at the bottom end of the bellows. The counterweight ball is a hollow - spherical shape, and multiple through - holes are provided on the surface of the counterweight ball.

[0009] Preferably, the tray has an internal cavity, and the side wall of the tray has a side groove. The side groove is annular, and the surface of the side groove has multiple infusion holes that connect the side groove and the cavity.

[0010] Preferably, the end of the infusion hole near the side groove is connected to an atomizing nozzle, and the atomizing nozzle is fixed to the surface of the side groove.

[0011] Preferably, a limiting ring is fixed on the top surface of the water tank, the limiting ring is sleeved on the outside of the tray, the height of the limiting ring is equal to the thickness of the tray, and a sealing ring is fixed on the inner ring surface of the limiting ring, the sealing ring is clamped between the limiting ring and the tray.

[0012] Preferably, the top surface of the tray is provided with a gripping groove, and there are multiple gripping grooves. The multiple gripping grooves are distributed in a circle with the center of the top surface of the tray as the center, and a pull rod is fixed between two parallel side walls of the gripping groove.

[0013] Preferably, a collar is fitted and fixed at the top of the lifting cylinder, and multiple screws are screwed to the bottom surface of the collar. The screws pass through the collar and are screwed to the bottom surface of the tray. The collar is inserted into the top slot of the reserved opening.

[0014] Preferably, the top surface of the water tank has a water inlet, which is an inverted convex-shaped round opening, and a sealing block is inserted and screwed into the inside of the water inlet.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The dust suppression spray device proposed in this invention uses a threaded sleeve with internal threads fixed to the bottom surface of the water tank top plate, and multiple sets of external threads of equal distance and size arranged vertically on the outer wall of the lifting cylinder, allowing the external threads to engage with the internal threads. This design provides the lifting cylinder with multiple lifting positions, and after each external thread and threaded sleeve are screwed together, the height of the lifting cylinder extending above the water tank top varies. Users can easily adjust the height of the lifting cylinder according to actual dust suppression needs, thereby changing the position of the tray and atomizing nozzles, achieving effective dust suppression spraying for dust sources at different heights, greatly improving the adaptability and flexibility of the device.

[0016] The tray sprays water injected by the pump outwards from all sides. The tray has an internal cavity with annular grooves on its side walls. Multiple infusion holes are located on the surface of these grooves, with one end connected to an atomizing nozzle fixed to the groove surface. This structure allows the clean water inside the cavity to be evenly sprayed outwards from the corresponding atomizing nozzles through the multiple infusion holes, achieving comprehensive dust suppression around the water tank's location. Additionally, users can install a nozzle at the center of the tray's top surface to spray directly above the water tank, further expanding the dust suppression area and enhancing the dust control effect.

[0017] Wear-resistant rubber rings are fitted and secured to both the top and bottom of the water tank. When the water tank needs to be moved, it is tilted so that the rubber rings contact the ground, allowing the tank to roll forward. Compared to traditional methods, this method significantly reduces labor and improves efficiency, making it particularly suitable for work environments requiring frequent equipment movement.

[0020] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8, the present invention provides a technical solution: a spray dust suppression device, including a water tank 1. A lifting cylinder 4 is movably inserted into the top of the water tank 1. A reserved opening 2 is formed on the top surface of the water tank 1. The reserved opening 2 is an inverted "convex" - shaped circular opening. A wire sleeve 3 is fixed to the bottom surface of the top plate of the water tank 1. The inner ring surface of the wire sleeve 3 has internal threads. The outer wall of the lifting cylinder 4 has external threads. The external threads and the internal threads are in mating connection. There are multiple groups of external threads, and multiple groups of external threads are arranged vertically at equal distances and of equal size. The reason for setting multiple groups of external threads is to set multiple lifting gears for the lifting cylinder 4. That is, after each external thread is screwed with the wire sleeve 3, the height of the lifting cylinder 4 extending out of the top of the water tank 1 is different.

[0022] A tray 5 is installed at the top of the lifting cylinder 4. A pump body 7 is installed inside the lifting cylinder 4. The water - pumping end of the pump body 7 penetrates through the bottom plate of the lifting cylinder 4, and a bellows 8 is sleeved and fixed on the water - pumping end of the pump body 7. The bellows 8 extends towards the bottom of the water tank 1. A counterweight ball 9 is sleeved and fixed at the bottom end of the bellows 8. The counterweight ball 9 is a spherical shape with a hollow interior. Multiple through - holes 10 are formed on the surface of the counterweight ball 9. The drain pipe of the pump body 7 is inserted into the tray 5. The tray 5 sprays the water injected by the pump body 7 through the four - week of the tray 5. A cavity 6 is formed inside the tray 5. An edge groove 11 is formed on the side wall of the tray 5. The edge groove 11 is an annular groove. Multiple liquid - injection holes 12 are formed on the surface of the edge groove 11. The liquid - injection holes 12 connect the edge groove 11 and the cavity 6. One end of the liquid - injection hole 12 close to the edge groove 11 is connected to an atomizing nozzle 13, and the atomizing nozzle 13 is fixed on the surface of the edge groove 11. A collar 17 is sleeved and fixed at the top end of the lifting cylinder 4. Multiple screws 18 are screwed on the bottom surface of the collar 17. After the screws 18 penetrate through the collar 17, they are screwed on the bottom surface of the tray 5. The collar 17 is inserted into the top - slot of the reserved opening 2. An injection port 19 is formed on the top surface of the water tank 1. The injection port 19 is an inverted convex - shaped circular opening. A plug block 20 is inserted and screwed into the injection port 19. A storage battery 22 is fixedly installed on the bottom surface of the tray 5. The storage battery 22 is connected to the pump body 7 through a wire. Press the lifting cylinder 4 against the bottom of the tray 5, and then use the screws 18 to fix the collar 17 to the bottom surface of the tray 5, thus completing the connection between the lifting cylinder 4 and the tray 5. After triggering the switch of the pump body 7, the pump body 7 sucks the clear water inside the water tank 1 through the bellows 8 and the counterweight ball 9, and then injects the clear water into the cavity 6. The clear water inside the cavity 6 is sprayed out from the corresponding atomizing nozzles 13 through multiple liquid - injection holes 12. That is, after the lifting cylinder 4 is lifted, it supports the tray 5. The tray 5 sprays water to the surrounding through multiple atomizing nozzles 13, realizing the spray dust suppression around the placement position of the water tank 1. And a nozzle can be installed at the center of the top surface of the tray 5 to realize the spray above the water tank 1. And an air pump can be installed on the top surface of the tray 5 to increase the pressure in the cavity 6, thereby increasing the water - spraying pressure of the atomizing nozzle 13. After unscrewing and removing the plug block 20 from the injection port 19, clear water can be injected into the water tank 1 through the injection port 19, and then the plug block 20 is screwed back into the injection port 19 to seal the injection port 19.

[0023] A limiting ring 14 is fixed to the top surface of the water tank 1. The limiting ring 14 is sleeved on the outside of the tray 5, and the height of the limiting ring 14 is equal to the thickness of the tray 5. A sealing ring 23 is fixed to the inner ring surface of the limiting ring 14, and the sealing ring 23 is clamped between the limiting ring 14 and the tray 5. A gripping groove 15 is opened on the top surface of the tray 5. There are multiple gripping grooves 15, which are circumferentially distributed with the center of the top surface of the tray 5 as the center. A pull rod 16 is fixed between two parallel side walls of the gripping groove 15. By holding the pull rod 16 and rotating the tray 5, the lifting cylinder 4 moves downward along the threaded sleeve 3 until the tray 5 is inserted into the limiting ring 14. At this time, the sealing ring 23 is clamped between the limiting ring 14 and the tray 5, thereby sealing and blocking the multiple atomizing nozzles 13.

[0024] Wear-resistant rubber rings 21 are fitted and fixed at both the top and bottom of the water tank 1. After the water tank 1 is tilted and placed, the wear-resistant rubber rings 21 contact the ground and push the water tank 1 to roll forward, thus saving the labor of moving the water tank 1.

[0025] Instructions for using the spray dust suppression device: Unscrew and remove the sealing block 20 from the water inlet 19. Inject clean water into the water tank 1 through the water inlet 19. After the clean water is injected, screw the sealing block 20 back into the water inlet 19 to achieve a seal. Place the lifting cylinder 4 against the bottom of the tray 5, and use screws 18 to fix the collar 17 to the bottom surface of the tray 5, completing the connection between the lifting cylinder 4 and the tray 5. The outer wall of the lifting cylinder 4 has multiple sets of equally spaced and sized external threads arranged vertically. After each external thread is screwed into the threaded sleeve 3, the height of the lifting cylinder 4 extending above the top of the water tank 1 is different. The appropriate external thread can be selected to connect with the threaded sleeve 3 according to actual needs, thereby setting the lifting position of the lifting cylinder 4. Hold the pull rod 16 and rotate the tray 5. The tray 5 drives the lifting cylinder 4 to rotate along the threaded sleeve 3, realizing the raising or lowering of the lifting cylinder 4 to adjust to the appropriate height. The pump body 7 is activated, drawing clean water from the water tank 1 through the bellows 8 and counterweight ball 9, and injecting the clean water into the cavity 6. The clean water inside the cavity 6 is sprayed out from the corresponding atomizing nozzles 13 through multiple infusion holes 12. The tray 5 sprays water around the water tank 1 using the multiple atomizing nozzles 13, achieving dust suppression by spraying water around the area where the water tank 1 is placed. A nozzle is installed at the center of the top surface of the tray 5 to spray water directly above the water tank 1. An air pump is installed on the top surface of the tray 5 to pressurize the cavity 6, thereby increasing the water spray pressure of the atomizing nozzles 13. The tray 5 is rotated by holding the lever 16, causing the lifting cylinder 4 to move downwards along the threaded sleeve 3 until the tray 5 is inserted into the limiting ring 14. At this point, the sealing ring 23 is clamped between the limiting ring 14 and the tray 5, achieving a sealed shielding of the multiple atomizing nozzles 13. The water tank 1 is tilted so that the wear-resistant rubber ring 21 at the top or bottom of the water tank 1 contacts the ground. Push water tank 1 to make it roll forward, saving the amount of labor required for handling.
