Description

Technical Field

[0001] This invention relates to the field of dust suppression device technology, specifically to an automatic dust suppression device for powder processing. Background Technology

[0002] In the fields of chemical industry, building materials, metallurgy and new material preparation, the processing of powder materials such as crushing, mixing, conveying and screening are key links in the production process. During the powder processing, a large amount of dust is easily generated due to material collision and airflow disturbance. This not only leads to excessive dust concentration in the workshop, but also endangers the respiratory health of operators and increases the risk of occupational diseases. Therefore, it is necessary to use automatic dust suppression devices to suppress the dust.

[0003] The prior art (publication number: CN116020219A, Chinese patent published on 2023-04-28) discloses a dust suppression device that is easy to move and fix, specifically relating to the field of municipal construction technology, including a box body, wherein a first groove is provided inside the box body, and a fixing block is fixedly connected inside the first groove. This invention, by setting a first driven shaft at one end of the drive shaft, addresses the need for dust suppression equipment during municipal construction to reduce dust in the surrounding air. When using small dust suppression equipment, manual pulling and moving are required to spray water mist around the construction site. Most small dust suppression equipment has feet and rollers at the bottom, allowing for both movement and fixation. When subjected to external force, the equipment's position is not shifted due to the rollers, ensuring effective positioning. Prior art (Chinese patent publication number CN221045723U, published on 2024-05-31) discloses a dust suppression device for cement production, relating to the field of dust suppression device technology. It includes a main body with suction ports fixedly installed on both sides and a water tank fixedly installed on the back. The lower end of the water tank contains residue. The main body of the device contains a dust collection box, and a spraying device is installed at the top of the dust collection box. Through the combined action of the spraying device, water tank, connecting pipes, water pressure regulator, flange interface, shrink water pipe, water pump, fixed base plate, connecting frame, and nozzle, the dust generated during cement production can be atomized and reduced, purifying the air in the workshop. The spraying device sprays water mist onto the cement production work area, reducing cement dust pollution and effectively reducing airborne dust, preventing the adverse effects of impurities solidifying, thus providing practical functionality. Existing technology (Publication No.: CN219722338U, Chinese Patent Publication Date: 2023-09-22) discloses a commercial concrete powder dust suppression device, relating to the field of concrete production dust suppression technology, including a movable base. A water tank is fixedly connected to the upper surface of the movable base, and a support column is fixedly connected to the upper surface of the movable base and to the right of the water tank. This invention utilizes a hydraulic rod to move a support block fixedly connected to the upper surface of the hydraulic rod upwards. This causes the support plate to move clockwise upwards under the action of steel balls and a fixed column, thereby adjusting the angle of the spray plate. When upward spraying for dust removal is required, starting motor two causes gear three fixedly connected to the upper surface of motor two to rotate, which in turn causes the annular toothed plate to rotate. Through the action of the annular toothed plate, the support plate rotates clockwise under the action of the fixed column, causing the right side of the support plate to overlap with the upper surface of the support block fixedly installed on the right side of the movable support column.

[0004] While existing automatic dust suppression devices for powder processing can adjust the spray angle, they cannot adjust the spray pressure synchronously, resulting in a limited dust suppression range. Furthermore, they are inconvenient to recycle and reuse liquid dripping from nearby points, leading to frequent liquid replenishment, which is not conducive to environmental protection and energy conservation, and has certain usage defects. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic dust suppression device for powder processing, in order to solve the problems mentioned in the background art. Although the automatic dust suppression devices for powder processing on the market can adjust the spray angle, they cannot adjust the spray pressure synchronously, resulting in a limited dust suppression range and inconvenience in recycling the liquid dripping from nearby points.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic dust suppression device for powder processing, comprising a liquid tank, a guide cylinder fixedly installed at the upper end of the liquid tank, a lifting pipe installed inside the guide cylinder, and a spray pipe movably installed at the upper end of the lifting pipe, the lifting pipe and the spray pipe being connected by a pipe, a piston plate being rotatably and sealed at the lower end of the lifting pipe, and a transmission assembly being provided between the guide cylinder and the lifting pipe, the transmission assembly driving the lifting pipe to rotate synchronously during the lifting and lowering process, a liquid infusion pipe being connected through the piston plate, and a liquid infusion pump being connected to the lower end of the liquid infusion pipe, an electric push rod fixedly installed on the upper surface of the liquid tank, a receiving tray fixedly installed at the output end of the electric push rod, and a filter mechanism being installed inside the receiving tray, the lifting pipe and the receiving tray being rotatably connected, a magnetic component for driving the spray pipe to rotate being provided between the filter mechanism and the spray pipe, and an airflow regulating component for collecting dust being provided between adjacent spray pipes.

[0007] Preferably, the liquid tank, guide cylinder and lifting pipe are coaxially arranged, and the lifting pipe, spray pipe and infusion pipe are connected. The spray pipe is evenly arranged on the top of the lifting pipe, and spray nozzles are evenly arranged on the spray pipe.

[0008] Preferably, the transmission assembly includes a spiral guide groove formed on the outer wall of the lifting tube, and a ball bearing is embedded in the inner wall of the guide cylinder. The ball bearing and the guide groove form a sliding structure and drive the lifting tube to move upward synchronously during the upward movement of the receiving tray. During the upward movement of the lifting tube, it is driven to rotate synchronously through the cooperation of the ball bearing and the guide groove.

[0009] Preferably, the filtration mechanism includes a filter plate that is lifted and installed inside the receiving tray, and a spring is fixedly connected between the filter plate and the receiving tray.

[0010] Preferably, the spray pipe and the lifting pipe are elastically rotatably connected, and a second magnetic block is fixedly installed on the spray pipe. A first magnetic block is uniformly fixedly installed on the upper surface of the filter plate, and the magnetic poles of the opposite surfaces of the first magnetic block and the second magnetic block are the same. When the spray pipe moves above the second magnetic block, it rotates elastically under the action of magnetic force.

[0011] Preferably, the filter plate reciprocates elastically up and down inside the receiving tray under the magnetic force of the first and second magnetic blocks, and the receiving tray and the lifting pipe are sealed together.

[0012] Preferably, the airflow regulating component includes an elastic membrane fixedly connected between two adjacent spray pipes, and the elastic membrane is arranged in a fan shape, with a through hole in the middle of the elastic membrane.

[0013] Preferably, an elastic film is attached to the lower surface of the elastic membrane, and the end of the elastic film away from the lifting tube is fixedly connected to the elastic membrane, and the area of ​​the elastic film is larger than the area of ​​the through hole.

[0014] Preferably, when the spray pipe rotates upward, the elastic film undergoes elastic deformation under air pressure, and when the elastic film undergoes elastic deformation, the through hole opens, and when the spray pipe rotates downward, the elastic film is sealed and adhered to the elastic membrane.

[0015] Preferably, a circulation pipe is fixedly connected between the lower part of the receiving tray and the guide cylinder, and a return pipe is connected to the upper part of the infusion pipe. Both the circulation pipe and the return pipe are equipped with one-way valves. When the piston plate moves upward inside the lifting pipe, the lower part of the guide cylinder draws the filtered liquid from the receiving tray through the circulation pipe. When the piston plate moves downward, the liquid inside the lower part of the guide cylinder enters the infusion pipe through the return pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are: the automatic dust suppression device for powder processing can adjust the spray pressure while adjusting the spray angle, and at the same time, it can effectively improve the dust suppression effect in conjunction with the airflow adjustment component, and can effectively filter and recover droplets falling from near the point, which is energy-saving and environmentally friendly. The specific details are as follows; 1. Equipped with a guide cylinder, a lifting pipe and a spray pipe, as the receiving pallet moves upward, it can drive the lifting pipe to move upward synchronously. At this time, the ball bearings on the inner side of the guide cylinder roll along the guide groove opened on the outer side of the lifting pipe, thereby driving the lifting pipe to rotate synchronously during the upward process. Furthermore, a first magnetic block and a second magnetic block are also provided. As the lifting pipe drives the spray pipe to rotate synchronously, the second magnetic block below the spray pipe will intermittently pass above the first magnetic block, causing the spray pipe to rotate elastically under the action of magnetic force, thereby further improving the uniformity of spraying.

[0017] 2. Equipped with an elastic membrane, through holes, and elastic film, the elastic membrane can be fanned as the spray pipe rotates vertically. When the spray pipe rotates upward, the elastic film can undergo elastic deformation under air pressure, opening the through holes and reducing airflow disturbance. When the spray pipe rotates downward, the elastic membrane and elastic film fan downward synchronously, reducing the air pressure above the elastic membrane. This causes the falling droplets and dust to converge towards the center, thereby reducing dust diffusion and improving the recovery efficiency of the dripping droplets.

[0018] 3. Equipped with a filter plate, circulation pipe, and return pipe, the filter plate can filter the collected droplets as it rises and falls. At the same time, the piston plate, driven by the rising and falling pipe, can be adjusted to allow the lower part of the guide cylinder to draw in the filtered liquid through the circulation pipe. When the piston plate moves down, the liquid drawn in by the lower part of the guide cylinder enters the delivery pipe through the return pipe, thereby increasing the spray pressure of the spray pipe and further improving the dust suppression effect.

[0021] Example 1: Existing automatic dust suppression devices for powder processing cannot synchronously adjust the spray pressure when adjusting the spray angle, resulting in a limited dust suppression range. To solve this technical problem, this example discloses the following technical content. Please refer to [link / reference]. Figures 1-7 As shown; an automatic dust suppression device for powder processing includes a liquid tank 1, a guide cylinder 2 fixedly installed at the upper end of the liquid tank 1, a lifting pipe 3 installed inside the guide cylinder 2, and a spray pipe 4 movably installed at the upper end of the lifting pipe 3. The lifting pipe 3 and the spray pipe 4 are connected by a pipe. A piston plate 5 is rotatably and sealed at the lower end of the lifting pipe 3. A transmission component is provided between the guide cylinder 2 and the lifting pipe 3. The transmission component drives the lifting pipe 3 to rotate synchronously during the lifting process. A liquid delivery pipe 6 is connected through the piston plate 5. A liquid delivery pump is connected to the lower end of the liquid delivery pipe 6. An electric push rod 7 is fixedly installed on the upper surface of the liquid tank 1. A receiving tray 8 is fixedly installed at the output end of the electric push rod 7. A filter mechanism is installed inside the receiving tray 8. The lifting pipe 3 and the receiving tray 8 are rotatably connected. A magnetic component for driving the spray pipe 4 to rotate is provided between the filter mechanism and the spray pipe 4.

[0022] The liquid tank 1, guide cylinder 2, and lifting pipe 3 are coaxially arranged, and the lifting pipe 3 is connected to the spray pipe 4 and the infusion pipe 6. The spray pipe 4 is evenly arranged on the top of the lifting pipe 3, and the spray pipe 4 is evenly arranged with spray nozzles 14. The transmission component includes a spiral guide groove 9 opened on the outer wall of the lifting pipe 3. The inner wall of the guide cylinder 2 is embedded with ball bearings 10, and the ball bearings 10 and the guide groove 9 form a sliding structure. During the upward movement of the receiving tray 8, the lifting pipe 3 is driven to move upward synchronously. During the upward movement of the lifting pipe 3, it is driven to rotate synchronously by the cooperation of the ball bearings 10 and the guide groove 9. The filtration mechanism includes a filter plate 12 that is lifted and installed inside the receiving tray 8, and a spring 11 is fixedly connected between the filter plate 12 and the receiving tray 8. The spray pipe 4 and the lifting pipe 3 are elastically rotatably connected, and a second magnetic block 15 is fixedly installed on the spray pipe 4. The upper surface of the filter plate 12 is... The first magnetic block 13 is uniformly fixedly installed on the surface, and the magnetic poles of the first magnetic block 13 and the second magnetic block 15 are the same on their opposite surfaces. When the spray pipe 4 moves above the second magnetic block 15, it rotates elastically under the action of magnetic force. The filter plate 12 reciprocates elastically up and down on the inner side of the receiving tray 8 under the action of magnetic force of the first magnetic block 13 and the second magnetic block 15. The receiving tray 8 and the lifting pipe 3 are sealed together. A circulation pipe 19 is fixedly connected between the receiving tray 8 and the lower part of the guide cylinder 2. A return pipe 20 is connected to the upper part of the infusion pipe 6. Both the circulation pipe 19 and the return pipe 20 are equipped with one-way valves. When the piston plate 5 moves up inside the lifting pipe 3, the lower part of the guide cylinder 2 draws the filtered liquid in the receiving tray 8 through the circulation pipe 19. When the piston plate 5 moves down, the liquid inside the lower part of the guide cylinder 2 enters the infusion pipe 6 through the return pipe 20.

[0023] The delivery pump at the lower end of the infusion pipe 6 is activated, allowing the infusion pipe 6 to deliver the dust-suppressing liquid to the lifting pipe 3. The liquid then enters the spray pipe 4 through a pipeline and is sprayed out through the nozzles 14 to suppress dust. Simultaneously, the electric push rod 7 is activated, driving the receiving tray 8 to reciprocate upwards and downwards. As the receiving tray 8 moves upwards, it drives the lifting pipe 3 to move upwards synchronously. At this time, the ball bearings 10 inside the guide cylinder 2 roll along the guide groove 9 on the outside of the lifting pipe 3, thereby driving the lifting pipe 3 to rotate synchronously during its ascent. As the lifting pipe 3 drives the spray pipe 4 to rotate synchronously, the dust-suppressing liquid below the spray pipe 4 is reduced. The second magnetic block 15 intermittently passes above the first magnetic block 13, causing the spray pipe 4 to rotate elastically under the action of magnetic force, thereby further improving the uniformity of spraying. As the filter plate 12 moves up and down, it can filter the dripping and converging droplets. At the same time, as the lifting pipe 3 drives the piston plate 5 to move up and down, the lower part of the guide cylinder 2 can draw the filtered liquid through the circulation pipe 19. When the piston plate 5 moves down, the liquid drawn into the lower part of the guide cylinder 2 enters the infusion pipe 6 through the return pipe 20, thereby increasing the spraying pressure of the spray pipe 4 and further improving the dust suppression effect.

[0024] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. Existing automatic dust suppression devices for powder processing are inconvenient for recycling waste liquid. To further solve this technical problem, this example discloses the following technical content, such as... Figures 4-10 As shown; an airflow regulating component for collecting dust is installed between adjacent spray pipes 4.

[0025] The airflow regulating component includes an elastic membrane 16 fixedly connected between two adjacent spray pipes 4. The elastic membrane 16 is arranged in a fan shape, and a through hole 17 is opened in the middle of the elastic membrane 16. An elastic film 18 is attached to the lower surface of the elastic membrane 16, and the end of the elastic film 18 away from the lifting pipe 3 is fixedly connected to the elastic membrane 16. The area of ​​the elastic film 18 is larger than the area of ​​the through hole 17. When the spray pipe 4 rotates upward, the elastic film 18 undergoes elastic deformation under air pressure. When the elastic film 18 undergoes elastic deformation, the through hole 17 is partially opened. When the spray pipe 4 rotates downward, the elastic film 18 is sealed and attached to the elastic membrane 16.

[0026] As the spray pipe 4 rotates vertically, it can cause the elastic membrane 16 to fan. When the spray pipe 4 rotates upward, the elastic film 18 can undergo elastic deformation under air pressure, causing the through hole 17 to open and reducing airflow disturbance. When the spray pipe 4 rotates downward, the elastic membrane 16 and the elastic film 18 fan downward synchronously, causing the air pressure above the elastic membrane 16 to decrease. This causes the falling droplets and dust to converge towards the center, thereby reducing dust diffusion and improving the capture and recovery efficiency of the falling droplets.
