[0050] With reference to Figure 3 and Figures 9-11 , the cleaning mechanism, the input end of the cleaning mechanism is in communication with part of the air outlet end of the ventilation assembly, and the output end is a backflush pipe 40, the fixed frame is connected with a rotating assembly, the backflush pipe 40 is connected to the output end of the rotating assembly, and the air outlet end of the backflush pipe 40 is towards the lower half of the filter piece.

[0051] The inner side of the rotating ring 12 is provided with an infrared distance measuring sensor 23, the infrared distance measuring sensor 23 adopts the prior art and is used for measuring the position of the mounting disc 29.

[0052] The cleaning mechanism comprises an electric valve 6 mounted on the second air outlet pipe 5, the air outlet end of the electric valve 6 is communicated with a connecting pipe 38, the end of the connecting pipe 38 away from the electric valve 6 penetrates through the fixing ring 9 and is communicated with a backflushing pipe 40, the end of the connecting pipe 38 extending into the inside of the fixing ring 9 is a hose, the rotating assembly comprises a motor 11 and a limiting frame 24 mounted on the first fixing plate 10, the output end of the motor 11 is coaxially fixedly connected with a gear 26, the limiting frame 24 is rotatably connected with an inner tooth ring 25, the inner side of the inner tooth ring 25 is in meshing cooperation with the gear 26 and the outer side is fixedly connected with the top of the backflushing pipe 40, the air outlet end of the backflushing pipe 40 faces the downward filter screen 31, the infrared distance sensor 23, the electric valve 6 and the motor 11 are all electrically connected with a controller, and the controller is mounted on the outer box 1.

[0053] The controller receives the signal of the infrared distance sensor 23 and controls the working state of the electric valve 6 and the motor 11, and after the installation disc 29 rotates, the backflushing cleaning operation is performed on the filter screen 31 with dust adhered.

[0054] The first fixing plate 10 is provided with an electric telescopic rod 27, the output end of the electric telescopic rod 27 is provided with a clamping part 28, the supporting frame 30 is fixedly connected with a transmission block 32, the clamping part 28 is clamped with the transmission block 32, the electric telescopic rod 27 is electrically connected with the controller, and the electric telescopic rod 27 penetrates through the inside of the inner tooth ring 25.

[0056] The bottom of the fixing ring 9, the top and the bottom of the rotating ring 12 are all provided with a penetrating groove 17, the two shielding plates 35 in the initial state shield the two penetrating grooves 17 on the rotating ring 12, the bottom of the outer box 1 is communicated with a collecting box 2, and the filter screen 31 and the penetrating groove 17 are all located above the collecting box 2.

[0057] The two groups of shielding plates 35 shield the penetrating grooves 17 in the initial state, so that air cannot enter the inside of the penetrating grooves 17 to blow away the dust collected in the collecting box 2, the shielding plates 35 are moved to open the penetrating grooves 17, so that the dust collected after cleaning can be conveniently collected through the penetrating grooves 17, and the dust falls into the inside of the collecting box 2 through the penetrating grooves 17.

[0058] The bottom of the backflush pipe 40 is communicated with a one-way pipe 39, the one-way pipe 39 is penetrated through the fixed ring 9 at the end far away from the backflush pipe 40, and is communicated with a storage tank 43, a one-way valve is installed inside the one-way pipe 39, the one-way valve is communicated in the direction from the backflush pipe 40 to the storage tank 43, the inside of the storage tank 43 contains water, and the top of the storage tank 43 is communicated with a communication shell 41, the top of the collecting box 2 is provided with an air inlet hole 42, and the end of the communication shell 41 far away from the storage tank 43 is communicated with the air inlet hole 42.

[0059] When the present application is used, the fan 7 works, the waste gas and dust in the factory are sucked into the inside of the outer box 1 through the bottom of the outer box 1, the airflow passes through the fixed ring 9 and the fan 7, and is then discharged through the air outlet pipe on the fixed shell 3.

[0060] When the airflow passes through the inside of the fixed ring 9, the airflow passes through the upper filter screen 31, the dust is intercepted and filtered through the filter screen 31, and the filtered air is transported to the required position through the second air outlet pipe 5 and the plurality of first air outlet pipes 4, so that subsequent waste gas treatment and heat recovery are facilitated.

[0061] In the initial state, the shielding plate 35 in the filter part shields the penetration groove 17, so that the airflow entering the inside of the outer box 1 is effectively prevented from directly entering the inside of the collecting box 2 through the penetration groove 17.

[0062] With the increase of the use time, the dust attached to the upper filter screen 31 is more and more, the airflow passing capacity of the upper filter screen 31 is gradually increased, and the blowing force of the airflow on the upper filter screen 31 is also gradually increased, in the process, the filter screen 31 is pushed by the airflow, the extrusion ball 22 is pushed through the installation disc 29, the compression spring telescopic rod 21 is compressed, the installation disc 29 is slid from the sliding groove 18 to the rotating groove 19, and the installation disc 29 is slid through the accommodation groove 20 on the rotating ring 12.

[0063] Since the installation disc 29 and the filter screen 31 are both arranged to be inclined by 10°, and the uppermost end and the lowermost end of the limiting plate 33 are provided with the counterweight 34, the upper filter screen 31 is attached with dust, so that the weight of the upper half of the filter part is greater than the weight of the lower half of the filter part, under the action of gravity, the installation disc 29 is naturally rotated by 180° in the inside of the rotating groove 19, so that the positions of the two filter screens 31 are exchanged, at this time, the clean filter screen 31 on the lower side is rotated to the upper airflow path, and can continue to filter, so that the filtering effect of the filter part is maintained.

[0064] When the installation disc 29 rotates, the rotating ring 12 is driven to rotate, and the rotating ring 12 will first press the clamping block 36 so that the second spring 37 is compressed. When the rotating ring 12 rotates 180°, the energy of the rotating ring 12 during oscillation can be consumed through the two sets of clamping blocks 36, thereby reducing the oscillation times of the rotating ring 12, so that the rotating ring 12 can be stabilized faster. Then, the rotating ring 12 is limited by the clamping of the two sets of clamping blocks 36 and the clamping groove, so as to avoid the rotation of the rotating ring 12 again, and facilitate the subsequent accurate movement of the installation disc 29 rotating 180° into the inside of the sliding groove 18.

[0065] The position of the installation disc 29 is monitored by the infrared distance sensor 23 at regular intervals. When the installation disc 29 is moved from the sliding groove 18 to the rotating groove 19, the distance between the installation disc 29 and the infrared distance sensor 23 reaches a threshold value, and the controller controls the cleaning mechanism to work.

[0066] When the installation disc 29 rotates in the inside of the rotating groove 19, the filter screen 31 with dust attached rotates to the lower part near the backflush pipe 40, the transmission block 32 on the filter element moves between the clamping jaws of the clamping part 28, and the transmission block 32 is clamped and fixed by the clamping part 28, so as to keep the stability of the filter screen 31.

[0067] Then, the electric valve 6 is controlled to change the communication state, so that the gas flow entering the inside of the second gas outlet pipe 5 enters the inside of the connecting pipe 38, and flows to the inside of the backflush pipe 40. Since the pipe diameter of the connecting pipe 38 is small, the gas will be accelerated, and the high-speed gas blows from the backflush pipe 40 to the filter screen 31 with dust attached, so as to promote the falling of the dust attached to the filter screen 31.

[0068] At the same time, the motor 11 is controlled, and the output end of the motor 11 drives the inner tooth ring 25 to reciprocating rotate through the gear 26, the inner tooth ring 25 drives the backflush pipe 40 to reciprocating rotate, the range of backflush of the backflush pipe 40 to the filter screen 31 is expanded, the overall cleaning effect of the dust attached to the filter screen 31 is improved, and the cleaning of the filter screen 31 is completed.

[0069] At the same time, the electric telescopic rod 27 is controlled, and the output end of the electric telescopic rod 27 quickly reciprocating telescopes, drives the transmission block 32, the support frame 30 and the filter screen 31 to vibrate together, and further promotes the falling of the dust attached to the filter screen 31 through the impact with the limiting plate 33 in the vibration process, so as to improve the cleaning effect.

[0070] After the installation disc 29 moves, the shielding plate 35 moves to open the through groove 17, the dust falling on the filter screen 31 enters the inside of the collection box 2 through the through groove 17, and the dust is collected and stored.

[0071] At the same time, a small part of the gas inside the backflushing pipe 40 enters the inside of the storage tank 43 through the one-way pipe 39, the part of the one-way pipe 39 inside the rotating ring 12 is a hose and has enough excess length, facilitating the reciprocating rotation of the backflushing pipe 40 without being hindered, the storage tank 43 contains water, the storage tank 43 is provided with a liquid level control device for controlling water inflow, ensuring that there is enough water inside the storage tank 43, the gas entering through the one-way pipe 39 passes through the water body and is blown into the inside of the collecting box 2 through the communication shell 41 and the air inlet hole 42, improving the humidity inside the collecting box 2, on the one hand, it can wet the dust, make the particles agglomerate and increase in weight, promote the settlement and accumulation of the fallen dust, reduce the diffusion of the dust, on the other hand, when the humidity is high, static electricity is not easy to occur, reducing the risk of dust explosion caused by static electricity.

[0072] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
