Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to an environmentally friendly dust removal device for waste gas treatment. Background Art

[0002] Industrial waste gas is a general term for various pollutant gases discharged into the air during fuel combustion and production processes in the factory area of ​​an enterprise. These waste gases include harmful gases such as carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, and harmful solids such as lead and mercury, beryllium, smoke and industrial dust. These pollutants discharged into the atmosphere will cause certain harm. These substances enter the human body through the respiratory tract through different pathways. Some of them cause direct harm, while others have an accumulation effect, which will cause more serious harm to human health.

[0003] In the existing industrial waste gas filtration, most of them only use a simple static filter to provide a certain speed for the waste gas, and cooperate with the fan directly installed inside the pipe to prevent the dust inside the waste gas from falling and adsorbing on the inner wall of the pipe due to the slow speed. In this way, the dust may gather on the surface of the fan blades, increase the load of the fan, and shorten the service life of the fan. When the filter is blocked, its filtering effect will not only become worse and worse, but as the filtering time increases, the impurities that have been filtered out will be carried away by the air again, resulting in a decrease in the dust removal effect of the device.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention arranges the positions of the exhaust pipe and the fan so that the fan has a pushing and guiding effect on the exhaust pipe, thereby avoiding the situation where the fan is directly installed inside the pipe body, causing dust to adhere to the fan blades and increase the fan load, thereby extending the service life of the fan.

[0017] (3) When the present invention is working, the meshing setting of the tooth groove and the pinion gear will drive the rotating column and the spiral scraper on the rotating column to rotate. Since the spiral scraper is in close contact with the surface of the filter plate, the dust adsorbed on the surface of the filter plate can be cleaned. In addition, through the setting of the cleaning plate, the spiral scraper will swing back and forth when the spiral scraper rotates, and the dust on the spiral scraper can be cleaned. As the cleaning plate swings back and forth, the dust will slide into the dust discharge chute and be discharged through the dust discharge chute, thereby avoiding the situation where the adsorbed dust will be carried away by the exhaust gas again, thereby increasing the dust removal efficiency of the device.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] An L-shaped hole 421 is provided inside the mounting block 42, one end of the L-shaped hole 421 is connected to the outside, the opening of the L-shaped hole 421 is located on the side of the mounting block 42 close to the arc column 4, and the opening of the L-shaped hole 421 faces the inner wall of the side of the hemispherical hole 143 provided on the slide groove 142, and a capsule-shaped cylinder 43 and a sliding column 44 are slidably provided perpendicular to each other inside the L-shaped hole 421, and the capsule-shaped cylinder 43 and the sliding column 44 are closely attached to each other at one end thereof, and the capsule-shaped cylinder 43 is provided at the opening of the L-shaped hole 421 One end of the capsule-shaped cylinder 43 is away from the inside of the L-shaped hole 421 and is designed to be spherical, and the end of the capsule-shaped cylinder 43 away from the inside of the L-shaped hole 421 is fitted inside the hemispherical hole 143, and a small spring 441 is fixedly installed between the sliding column 44 and the inner wall of the L-shaped hole 421 away from the capsule-shaped cylinder 43. The purpose of this arrangement is to facilitate the capsule-shaped cylinder 43 to cooperate with the next hemispherical hole 143 to limit the mounting block 42 after the knocking action of 41 on 321 is completed.

[0038] A fan-shaped cavity 501 is provided inside the side of the special-shaped mounting column 5 close to the gear ring 3, and an ash discharge groove 502 is provided on the side of the fan-shaped cavity 501 away from the gear ring 3. The end of the ash discharge groove 502 away from the axis of the gear ring 3 is connected to the outside, and both ends of the fan-shaped cavity 501 are fixedly connected with fixed cylinders 503, and a rotating column 51 is installed inside the fixed cylinder 503 for common rotation. The purpose of this arrangement is to facilitate the installation of the rotating column 51 and to facilitate the discharge of dust.

[0039] A pinion 52 is fixedly installed at one end of the rotating column 51 away from the axis of the gear ring 3, and the pinion 52 is transmission connected to the tooth groove 302. A spiral scraper 53 is fixedly installed on the side wall of the rotating column 51, and the spiral scraper 53 is arranged to be in contact with the surface of the gear ring 3. A rotating column 54 is rotatably installed between the opposite inner walls of the dust discharge groove 502, and a cleaning plate 541 is fixedly connected to the rotating column 54, and the cleaning plate 541 is in close contact with the upper surface of the spiral scraper 53. The purpose of this arrangement is to facilitate the cleaning of the surface of the gear ring 3.

[0040] When in use, the exhaust gas is discharged into the interior of the pipe body 1 through the exhaust pipe 11. Through the arrangement of the exhaust pipe 11 and the fan 13, the fan 13 has a pushing and guiding effect on the exhaust pipe 11, thereby avoiding the situation where the fan 13 is directly installed inside the pipe body 1, causing dust to adhere to the blades of the fan 13, resulting in an increase in the load of the fan 13, and extending the service life of the fan 13.

[0041] The exhaust gas passes through the two sets of filter plates 31, which can absorb the dust inside the exhaust gas to achieve the dust removal effect, and the motor 221 works to drive the rotating shaft 22 and the large gear 23 to rotate. Due to the meshing setting of the large gear 23 and the gear ring 3, the gear ring 3 can be driven to rotate synchronously, and the filter plate 31 and the vibration plate 32 can rotate synchronously.

[0042] Among them, due to the limiting effect of the hemispherical hole 143 on the capsule-shaped cylinder 43, the position of the mounting block 42 is fixed, and the large spring 411 will be squeezed when the vibration plate 32 rotates. When the elastic force of the large spring 411 gradually increases with the rotation of the vibration plate 32, the setting of the contact surface between the hemispherical hole 143 and the capsule-shaped cylinder 43, and the contact setting between the capsule-shaped cylinder 43 and the sliding column 44 will cause squeezing of the sliding column 44 and the small spring 441. When the capsule-shaped cylinder 43 moves to disengage from the hemispherical hole 143, the large spring 411 extends, pushing the mounting block 42 to slide inside the slide groove 142. At the same time, the large spring 411 and the impact block 41 move synchronously, and the impact block 41 will impact the vibration plate 32, and then the vibration can be transmitted inside the filter plate 31 through the transmission of the vibration plate 32, so that the dust adsorbed inside the filter plate 31 can be cleaned and dropped, and then the capsule-shaped cylinder 43 will cooperate with the next hemispherical hole 143 to facilitate the continuous cleaning work.

[0043] When the tooth ring 3 rotates, the meshing setting of the tooth groove 302 and the pinion 52 will drive the rotating column 51 and the spiral scraper 53 on the rotating column 51 to rotate. Since the spiral scraper 53 is in close contact with the surface of the filter plate 31, the dust adsorbed on the surface of the filter plate 31 can be cleaned, and the cleaning plate 541 can swing back and forth when the spiral scraper 53 rotates, and the dust on the spiral scraper 53 can be cleaned. When the cleaning plate 541 swings upward, the dust will fall off and be discharged to the inside of the drawer 161 in the installation box 16 through the dust discharge groove 502, and the dust is collected, avoiding the situation that the adsorbed dust will be carried away by the exhaust gas again. When the device is working, it will clean the inside of the filter plate 31 and the contact surface with the exhaust gas, avoiding the situation that the filter plate 31 is blocked due to dust accumulation inside and on the surface of the filter plate 31 due to long-term use, thereby reducing the dust removal efficiency.
