Technical Field
[0001] This utility model relates to the technical field of dust recovery equipment, specifically to a dust treatment and recovery device. Background Technology
[0002] Acetylene is required for metal welding and cutting to ensure smooth operation. In existing technologies, acetylene is mainly produced by the decomposition of calcium carbide and water. During the reaction of calcium carbide and water to produce acetylene, some fine calcium lime particles are generated. These particles may form calcium lime dust with the gas flow generated by the reaction. If calcium lime dust is absorbed by the human body, it will pose a threat to human health. Therefore, it is necessary to recycle and process it.
[0003] Existing electrolyzed lime dust recovery devices typically use filters to remove electrolyzed lime dust, thus preventing it from being directly released into the air and affecting the surrounding environment and people's health. However, electrolyzed lime dust easily adheres to the filter screen, causing blockage and requiring manual cleaning, which increases labor costs and affects filtration efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a dust treatment and recycling device that solves the problem in the prior art where carbide lime dust easily adheres to the filter screen, causing blockage and requiring manual cleaning, which increases labor costs and affects filtration efficiency.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0006] A dust treatment and recovery device includes a treatment cylinder. An air inlet pipe is located at the bottom of the outer wall of the treatment cylinder and communicates with its interior. A support ring is located above the air inlet pipe inside the treatment cylinder. The outer ring of the support ring is fixedly connected to the inner wall of the treatment cylinder. A filter screen is located on the top of the support ring, surrounding its inner ring. A support plate is closed at the top of the filter screen.

The bottom end of the rod is movably placed inside the filter screen, and a cleaning assembly for cleaning the inner wall of the filter screen is located on its outer side. An air suction pipe is located on the top of the treatment cylinder and communicates with its interior. A fan is connected to the end of the air suction pipe furthest from the treatment cylinder.
[0007] A further technical solution is that the drive assembly includes an air guide tube, the outer wall of which is fixedly connected to the inner wall of the processing tube and located above the support plate. The top of the vertical rod is provided with a drive disc that slides and adapts to the inside of the air guide tube. The top of the air guide tube is provided with L-shaped mounting strips arranged in a ring array. The end of the mounting strip away from the top of the air guide tube is horizontally placed above the drive disc, and a magnetic block is provided on its bottom side. The top side of the drive disc is provided with a magnet that attracts the magnetic block. A support spring is sleeved on the outer side of the end of the vertical rod located above the support plate. The two ends of the support spring are fixedly connected to the drive disc and the support plate, respectively.
[0008] A further technical solution is that an auxiliary disc is provided between the air guide tube and the support plate. The annular sidewall of the auxiliary disc is fixedly connected to the inner sidewall of the treatment tube. An air guide hole is provided on the auxiliary disc, penetrating its upper and lower sides.

Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0020] Example 1:
[0021] See Figure 1 The present invention discloses a dust treatment and recovery device, comprising a processing cylinder 1, an air inlet pipe 2 connected to the interior of the outer wall of the processing cylinder 1, a support ring 3 located above the air inlet pipe 2 inside the processing cylinder 1, the outer ring of the support ring 3 being fixedly connected to the inner wall of the processing cylinder 1, a filter screen cylinder 4 surrounding the inner ring of the support ring 3, a support plate 5 closed at the top of the filter screen cylinder 4, a vertically arranged vertical rod 6 slidably connected to the center of the support plate 5, a driving assembly for driving the vertical rod 6 to slide up and down above the support plate 5, the bottom end of the vertical rod 6 being movably placed inside the filter screen cylinder 4, and a cleaning assembly for cleaning the inner wall of the filter screen cylinder 4 being provided on its outer side, and an air suction pipe 7 connected to the interior of the processing cylinder 1 at the top, with a fan 8 connected to the end of the air suction pipe 7 away from the processing cylinder 1.
[0022] Specifically, the blower 8 is controlled to operate, and the dust-laden gas enters the processing cylinder 1 through the inlet pipe 2. Under the suction force of the blower 8, the dust-laden gas passes through the inner ring of the support ring 3 and enters the filter cylinder 4. The filter cylinder 4 filters the dust in the gas, and the filtered gas passes through the filter cylinder 4 and enters the suction pipe 7, and finally is discharged through the outlet of the blower 8. The outlet of the blower 8 is connected to the cooling device in the prior art for cooling the gas, which is common knowledge to those skilled in the art, and those skilled in the art can directly obtain the corresponding installation relationship and structure based on common knowledge. When too much dust adheres to the inner wall of the filter cylinder 4 and causes blockage, the drive component drives the vertical rod 6 to slide vertically relative to the support plate 5, thereby driving the cleaning component to move vertically to clean the dust adhering to the inner wall of the filter cylinder 4, thereby avoiding the need for manual cleaning by personnel, reducing labor costs, and improving the filtration effect. It should be noted that the end of the suction pipe 7 placed inside the processing cylinder 1 can be connected to a suction hood.
[0023] Example 2
[0024] Based on the aforementioned Example 1, refer to Figure 1 , Figure 2 As shown, the drive assembly includes an air guide duct 9. The outer wall of the air guide duct 9 is fixedly connected to the inner wall of the processing cylinder 1 and is located above the support plate 5. The top of the vertical rod 6 is provided with a drive disc 11 that is slidably adapted to the inside of the air guide duct 9. The top of the air guide duct 9 is provided with an L-shaped mounting strip 12 arranged in a ring array. One end of the mounting strip 12 away from the top of the air guide duct 9 is horizontally placed above the drive disc 11, and a magnet 13 is provided on its bottom side. The top side of the drive disc 11 is provided with a magnet 14 that attracts the magnet 13. A support spring 15 is sleeved on the outer side of the end of the vertical rod 6 located above the support plate 5. The two ends of the support spring 15 are fixedly connected to the drive disc 11 and the support plate 5, respectively. The support spring 15 is in a compressed state under the gravity of the drive disc 11, the vertical rod 6, the magnet 14, and the cleaning assembly, so that the drive disc 11 slides to the bottom of the inside of the air guide duct 9.
[0025] Specifically, when the filter cylinder 4 is not clogged, the control fan 8 operates. The suction force of the fan 8 causes air to flow inside the treatment cylinder 1, ultimately exerting a thrust on the drive disc 11. Since the support spring 15 is in a compressed state and has elastic potential energy, it exerts an upward elastic force on the support plate 5. At the same time, there is an attractive force between the magnet 14 and the magnetic block 13. At this time, the sum of the weights of the drive disc 11, the vertical rod 6, the magnet 14, and the cleaning assembly is less than the sum of the thrust, attraction, and elastic force. Therefore, under the action of the thrust, attraction, and elastic force, the drive disc 11 is pushed upward and slides out of the air guide duct 9. The upward movement of the drive disc 11 causes the vertical rod 6 and the cleaning assembly to move upward. However, as dust accumulates on the inner wall of the filter cylinder 4, it will cause blockage, resulting in less and less air passing through the filter cylinder 4 inside the treatment cylinder 1. This reduces the thrust exerted by the flowing air on the drive disc 11. When the thrust generated by the airflow drops to a certain level, the sum of the gravity of the drive disc 11, the vertical rod 6, the magnet 14, and the cleaning component is greater than the sum of the thrust, suction, and elasticity. Under the action of gravity, the drive disc 11, the vertical rod 6, and the cleaning component move downwards. The downward movement of the cleaning component completes the cleaning of the dust adhering to the inner wall of the filter cylinder 4, avoiding the need for manual cleaning by staff, reducing labor costs, and improving the filtration effect.
[0026] It is important to note that appropriate magnets 14 and magnetic blocks 13 can be selected to generate attraction. This ensures that when the drive disc 11 rises, the compression of the support spring 15 decreases, and its elastic force decreases. However, the distance between magnets 14 and magnetic blocks 13 decreases, and the attraction between them increases. Conversely, when the drive disc 11 falls, the compression of the support spring 15 decreases, and its elastic force increases. However, the distance between magnets 14 and magnetic blocks 13 increases, and the attraction between them decreases. Ultimately, this ensures that the sum of the elastic force of the support spring 15 on the drive disc 11 and the attraction between magnets 14 and magnetic blocks 13 is a fixed value. This ensures that the drive assembly can drive the cleaning assembly to clean the inner wall of the filter cylinder 4 under the action of thrust.
[0027] As a preferred implementation method, see [link / reference] Figure 1 As shown, an auxiliary disk 16 is provided between the air guide duct 9 and the support plate 5. The annular sidewall of the auxiliary disk 16 is fixedly connected to the inner sidewall of the processing cylinder 1. An air guide hole 17 is provided on the auxiliary disk 16, penetrating its upper and lower sides. The inner annular diameter of the air guide hole 17 increases from top to bottom and is arranged in a frustum shape. The top of the air guide hole 17 is connected to the bottom of the interior of the air guide duct 9. By providing the air guide hole 17, it is convenient to guide the filtered gas into the interior of the air guide duct 9, which provides a thrust to the drive disk 11.
[0028] As a preferred implementation method, see [link / reference] Figure 1As shown, a vertically arranged limiting rod 18 is provided on the bottom side of the end of the mounting strip 12 that is away from the top of the air guide tube 9 and is horizontally placed above the drive disc 11. The bottom end of the limiting rod 18 slides through the drive disc 11 and is connected to the top of the support plate 5. Specifically, by setting the limiting rod 18, the drive disc 11 can be limited so that the drive disc 11 can only move in the vertical direction.
[0029] Example 3
[0030] Based on the aforementioned Example 1, refer to Figure 1 As shown, the cleaning assembly includes connecting rods 19, mounting rings 21, and brush bristles. Connecting rods 19 are arranged in a straight line along the axis of the outer side of the vertical rod 6. Connecting rods 19 located at the same horizontal position are arranged in a ring array on the outer side of the vertical rod 6, and the end of each connecting rod away from the vertical rod 6 is connected to the same mounting ring 21. The brush bristles are evenly arranged on the outer ring side of the mounting ring 21 and slide against the inner wall of the filter cylinder 4. Under the action of the driving assembly, the brush moves vertically, thereby cleaning the inner wall of the filter cylinder 4.
[0031] Example 4
[0032] Based on the aforementioned Example 1, refer to Figure 3 As shown, a dustproof cloth 23 is provided on the bottom side of the support plate 5 surrounding the outside of the vertical rod 6. The bottom end of the dustproof cloth 23 is connected to the outside of the vertical rod 6, which is movably placed inside the filter cylinder 4. By setting the dustproof cloth 23, dust can be prevented from moving out through the gap between the vertical rod 6 and the support plate 5. It should be noted that the dustproof cloth 23 can be set with an appropriate size according to actual needs, so as to avoid affecting the vertical movement of the vertical rod 6.
[0033] Example 5
[0034] Based on the aforementioned Example 1, refer to Figure 1 As shown, a collection cylinder 24 is connected to the bottom of the processing cylinder 1. A slide valve 25 is provided at the bottom of the inside of the collection cylinder 24. By setting the slide valve 25, it is convenient to discharge the dust deposited in the processing cylinder 1 for the same recycling process.
