Description

Technical Field

[0001] The invention relates to the technical field of environmental protection, in particular to air pollution prevention and control equipment. Background Art

[0002] Construction dust refers to dust particles generated during activities such as house construction, road and pipeline construction, and material transportation. These particles can seriously pollute the atmospheric environment. They not only reduce the transparency of the atmosphere, resulting in reduced visibility, but can also combine with other pollutants to form complex pollution, further exacerbating the degree of air pollution. The harm of construction dust to human health cannot be ignored. Particles in dust may enter the human body through the respiratory tract, causing damage to the respiratory system, cardiovascular system, etc., and increase the incidence of respiratory diseases, cardiovascular diseases and other diseases.

[0003] At present, the method for dealing with dust is to sprinkle water regularly at the construction site to keep the ground moist and reduce the generation of dust. The time and frequency of sprinkling water need to be flexibly adjusted according to the weather and construction conditions. In addition, there is a device for filtering dust through a filter. The patent number is 202410724303.1, which is called an atmospheric environmental pollution control and cleaning device. The filter is filtered through a filter disc and then the filter disc is cleaned. For this reason, it can be known that the filter disc can filter, so the holes on the filter disc can prevent dust from passing through, and the filter disc needs to be cleaned after dust adheres to it. Due to the narrow holes of the filter disc, dust accumulates in the holes to a certain extent, and even produces a stuck effect. Therefore, to a certain extent, even if the filter disc is cleaned, it is difficult to achieve a state where the holes of the filter disc are all through. In view of this situation, the present invention proposes to replace the filter disc and avoid clogging even after cleaning, so as to continuously filter the dust in the gas. Summary of the invention

[0004] The object of the present invention is to provide an air pollution control device to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an air pollution prevention and control device, comprising a box for containing dust, an outer support plate and a collection tank are fixed on the box, a filter unit is installed on one side of the outer support plate, and the lower end of the filter unit is connected to the collection tank;

[0006] The filter unit includes an outer ring frame and an inner ring frame. The outer side of the outer ring frame is provided with a conveying pipe 1 and a conveying pipe 2 for air inlet and outlet. The inner ring frame is sleeved into the outer ring frame. A rotatable filter component is sleeved between the outer ring frame and the inner ring frame. The inner ring frame can exhaust air downwards to discharge dust in the filter component into the box.

[0007] Furthermore, a cavity is opened on the outer side of the box body, and a sealing bag layer is installed in the cavity. The bag layer is concave inward and has recovery elasticity. A horizontal support plate is fixed in the bag layer. When the air pressure inside the box body increases, the bag layer can be deformed to balance the air pressure inside the box body.

[0008] Furthermore, the outer ring frame and the inner ring frame are both fixed on one side of the outer support plate, and the conveying pipe 1 and the conveying pipe 2 on the outer ring frame are in a straight line with the through hole. The filtering component includes a driving circle layer, and a plurality of circumferentially distributed filter tubes are fixed to the outside of the driving circle layer, wherein the two horizontal filter tubes are respectively connected to the conveying pipe 1 and the conveying pipe 2 on both sides, and the driving circle layer is sleeved on the outside of the inner ring frame. When the driving circle layer rotates, different filter tubes are connected to the conveying pipe 1 and the conveying pipe 2 on both sides, and the filter tubes are used to filter dust in the gas.

[0009] Furthermore, an outer side of the inner circular frame is provided with an outer card track, the outer card track cooperates with the driving circle layer, and the inner wall of the outer card track and the driving circle layer are smooth.

[0010] Furthermore, a support cover is fixed to the outside of the outer ring frame, a servo motor is fixed to the outside of the support cover, an inner gear ring is fixed to the outside of the driving ring layer, a rotating shaft is fixed to the output end of the servo motor, a transmission gear is fixed on the outer wall of the rotating shaft, and the transmission gear is meshed with the inner gear ring to drive the driving ring layer to rotate.

[0011] Furthermore, a conical sleeve is fixed inside the filter tube, and the conical sleeve is arranged to penetrate. The end of the conical sleeve with a smaller diameter faces the inner end of the filter tube, and a support spring is fixed to the end of the conical sleeve with a smaller diameter. A support ball is fixed to the outer end of the support spring, and the support ball is hollow and penetrates. A densely distributed fluff layer is fixed to the outer side of the support ball. When the conical sleeve takes in air, dust is stuck in the fluff layer.

[0012] Furthermore, the fluff layer is rigidly arranged, and the gaps in the fluff layer gradually increase from the inside to the outside.

[0013] Furthermore, a cleaning part is installed in the collection tank, and the cleaning part includes a rotating plate and cleaning bristles installed on the rotating plate, and the cleaning bristles can extend into the downward filter tube.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0016] 1. During the air filtration process, the dust is blocked by the fluff layer to complete the filtering effect. As the fluff layer rotates to face vertically downward, the dust in the fluff layer is blown out from the inside to the outside under the action of the air pump gas. The gap of the fluff layer is variable, which can minimize the accumulation of dust in the fluff layer.

[0017] 2. The air pump blows air from top to bottom, pushing the support ball outward. There are relatively large gaps in the fluff layer to facilitate dust falling. The air pressure inside the box will increase, and the bladder layer will be forced to move outward. After that, the bladder layer will recover and wait for the next inflation to prevent the dust in the box from moving outward.

[0018] 3. The cleaning bristles will also extend into the filter tube and contact the fluff layer. Under the action of the driving motor, the fluff layer is moved to achieve dust cleaning. The fluff layer is hard, so the entire fluff layer moves to shake off the dust. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 7 The present invention provides a technical solution: In the treatment of dust in the atmosphere, it is necessary to separate gas from dust, and there are various devices used for separation. At present, the filtering method used will cause dust to remain on the filtering device and block the filtering holes, thereby affecting the filtering effect. Based on this, an air pollution prevention and control device is required, including a box body 1 for holding dust, an outer support plate 3 and a collection tank 2 are fixed on the box body 1, a filter unit 4 is installed on one side of the outer support plate 3, and the lower end of the filter unit 4 is connected to the collection tank 2;

[0030] The filter unit 4 includes an outer ring frame 41 and an inner ring frame 42. The outer side of the outer ring frame 41 is provided with a conveying pipe 1 411 and a conveying pipe 2 412 for air inlet and outlet. The inner ring frame 42 is sleeved into the outer ring frame 41. A rotatable filter component 43 is sleeved between the outer ring frame 41 and the inner ring frame 42. The inner ring frame 42 can exhaust air downward to discharge dust in the filter component 43 into the box body 1. The filter component 43 can be rotated by fixing the outer ring frame 41 and the inner ring frame 42 so that the filter component 43 can be filtered at different positions to maintain the smoothness of the filtering. During the filtering process, the dust can be automatically discharged to avoid affecting the filtering.

[0031] A cavity 11 is provided on the outer side of the box body 1, and a sealing bag layer 12 is installed in the cavity 11. The bag layer 12 is concave inwardly and has recovery elasticity. A horizontal support plate 13 is fixed in the bag layer 12. When the air pressure inside the box body 1 increases, the bag layer 12 can be deformed to balance the air pressure inside the box body 1. When gas is injected into the box body 1, the air pressure inside it increases, and the bag layer 12 begins to expand, which has a buffering effect to avoid direct gas leakage outward, but to achieve slow leakage, and minimize the movement of dust outward with the gas. In addition, the support plate 3 supports the bag layer 12 to avoid the bag layer 12 from flipping and protruding outward. The bag layer 12 has an elastic effect. As the internal air pressure decreases, it can automatically recover and wait for the next force.

[0032] The outer ring frame 41 and the inner ring frame 42 are both fixed on one side of the outer support plate 3. The delivery pipe 1 411 and the delivery pipe 2 412 on the outer ring frame 41 are in a straight line with the through hole 422. The filter component 43 includes a driving circle layer 431. A plurality of circumferentially distributed filter tubes 437 are fixed to the outer side of the driving circle layer 431, wherein two transverse filter tubes 437 are respectively connected with the delivery pipe 1 411 and the delivery pipe 2 412 on both sides. The driving circle layer 431 is sleeved on the outer side of the inner ring frame 42. When the driving circle layer 431 rotates, different filter tubes 437 are connected with the delivery pipe 1 411 and the delivery pipe 2 412 on both sides. The filter tube 437 is used to filter dust in the gas. After the filter component 43 rotates, different filter tubes 437 are connected with the delivery pipe 1 411 and the delivery pipe 2 412 on both sides for each transmission angle, so that the filter tube 437 can maintain a good filtering effect and avoid excessive blockage, and the dust also moves with the gas.

[0033] An outer card channel 421 is provided on the outer side of the inner circular frame 42, and the outer card channel 421 cooperates with the driving circle layer 431. The inner walls of the outer card channel 421 and the driving circle layer 431 are smooth, so that the driving circle layer 431 can rotate smoothly, while also avoiding leakage of gas inside the driving circle layer 431 as much as possible.

[0034] A support cover 436 is fixed to the outside of the outer ring frame 41, a servo motor 435 is fixed to the outside of the support cover 436, an inner gear ring 432 is fixed to the outside of the driving circle 431, a rotating shaft 434 is fixed to the output end of the servo motor 435, a transmission gear 433 is fixed on the outer wall of the rotating shaft 434, the transmission gear 433 is meshed with the inner gear ring 432, and is used to drive the driving circle 431 to rotate, the servo motor 435 drives the rotating shaft 434 to rotate, and also rotates the transmission gear 433, so that the driving circle 431 rotates.

[0035] A conical sleeve 438 is fixed inside the filter tube 437. The conical sleeve 438 is set to penetrate. The end of the conical sleeve 438 with a smaller diameter faces the inner end of the filter tube 437. A support spring 439 is fixed to the end of the conical sleeve 438 with a smaller diameter. A support ball 401 is fixed to the outer end of the support spring 439. The support ball 401 is hollow and penetrates. A densely distributed fluff layer 402 is fixed to the outside of the support ball 401. When the conical sleeve 438 takes in air, dust is stuck in the fluff layer 402. The inside of the conical sleeve 438 is used to pass gas, and when the gas is filtered, it moves from the larger end to the smaller end. The fluff layer 402 in the conical sleeve 438 blocks the dust inside the gas, and the gas moves along the gaps in the fluff layer 402 to block the dust as much as possible.

[0036] The fluff layer 402 is rigidly configured, and the gaps between the fluff layers 402 gradually increase from the inside to the outside. The gaps between the fluff layers 402 are subjected to a large degree of force variation. When the fluff layer 402 is subjected to external force, the dust stuck inside it can be shaken off, and the dust can be cleaned up as quickly as possible without being blocked like filter holes, thereby improving operability. In addition, the fluff layer 402 can move as a whole after being subjected to force, and can be deformed even at locations with small gaps, thereby shaking off all the dust.

[0037] A cleaning part 21 is installed in the collection tank 2, and the cleaning part 21 includes a rotating plate 211 and cleaning bristles 212 installed on the rotating plate 211. The cleaning bristles 212 can extend into the downward filter tube 437. A support plate 213 is fixed in the collection tank 2, and a driving motor 214 is fixed at the lower end of the support plate 213. The output end of the driving motor 214 is fixed to the rotating plate 211. The length of the cleaning bristles 212 is adapted and can move into the downward filter tube 437. Under the action of the driving motor 214, the fluff layer 402 is subjected to external force.

[0038] A bent air vent 423 is provided in the inner circular frame 42, and the lower end of the air vent 423 is connected to a downward filter tube 437. An air inlet pipe 424 for connecting to an air pump is fixed to the outer side of the air vent 423. The air pump gas moves to the air vent 423 and blows toward the downward filter tube 437, blowing from the dense side of the fluff layer 402 to the sparse side, so as to facilitate the removal of dust.

[0039] The working principle of the present invention is as follows: during the air filtering process, the gas is transmitted to the delivery pipe 1 411 through the air pump, then passes through the filter tube 437, and then moves out from the delivery pipe 2 412. When passing through the filter tube 437, the support ball 401 is pushed toward the narrow side of the conical sleeve 438 under the thrust of the gas, so that the fluff layer 402 close to the support ball 401 will be tighter, and the gas passing through will cause dust to remain, and the dust is blocked by the fluff layer 402 to complete the filtering effect. After that, the fluff layer 402 rotates to be vertically downward, and the dust in the fluff layer 402 is blown out from the inside to the outside under the action of the air pump gas. Compared with the filter plate, the gap of the fluff layer 402 is variable, which can minimize the accumulation of dust in the fluff layer 402.

[0040] In addition, when the fluff layer 402 is vertical, the air pump blows air from top to bottom to push the support ball 401 to move outward, and the outward movement space gradually increases, so that there is a relatively large gap in the fluff layer 402, which is convenient for dust to fall. In addition, after the gas moves into the box 1, the air pressure inside the box 1 will increase, causing the inwardly concave bladder layer 12 to be forced to move outward, but is prevented from moving completely outward by the support plate 13. Later, when the gas inside the box 1 gradually leaks, the bladder layer 12 recovers and waits for the next inflation to prevent the dust in the box 1 from moving outward.

[0041] When the filter tube 437 is rotated to face downward, the cleaning bristles 212 will be bent and extended into the filter tube 437 to contact the fluff layer 402. The driving motor 214 drives the cleaning bristles 212 to rotate, so that the fluff layer 402 is moved to clean the dust. In addition, when the support ball 401 moves outward, the contact range between the cleaning bristles 212 and the fluff layer 402 is increased, and the fluff layer 402 is hard, so the entire fluff layer 402 moves to shake off the dust.
