An outlet pipe 49 is connected to the front of the bellows 28.

[0024] Advantageously, the bellows 28 is provided with a detachable top cover, which makes it easy for personnel to open the internal space of the bellows 28 for the installation of the bag structure.

[0025] Advantageously, the connecting pipe 33 and the input pipe 14 are connected by a flange structure to form a connection.

[0026] Advantageously, the upper pipe 25 and the lower pipe 31 are connected by a flange structure to form a connection.

[0027] Advantageously, the first inclined plate 23 and the second inclined plate 32 are inclined plate structures that arch towards the middle.

[0028] Advantageously, a conduit 22 is fixedly installed inside the first inclined plate 23, and a gas pressure sensor 24 is connected to the top of the conduit 22. The conduit 22 is connected to the inside of the top tank 21, and the pressure inside the top tank 21 is detected by the gas pressure sensor 24.

[0029] Advantageously, the bag structure includes a flange ring 45, an inner hole 52 is provided in the flange ring 45, a bag 48 is provided in the inner hole 52, and the upper side of the bag 48 is pressed and fixed in the flange ring 45 by a fixing ring 44.

[0030] Advantageously, multiple protruding plates 43 are fixedly arranged around the fixing ring 44, multiple bottom rods 57 are fixedly arranged on the lower side of the fixing ring 44, multiple bag sleeves 47 are fixed inside the bag 48, and the bottom rods 57 are inserted into the bag sleeves 47.

[0031] Advantageously, the outer surface of the cloth bag 48 is fixed with a flange 54, the inner hole 52 is fixed with a flange 53, the flange 53 is fixed with a mounting groove 51 around its perimeter, the fixing ring 44 presses and fixes the flange 54 to the upper end face of the flange 53, and the protruding plate 43 is fixed in the mounting groove 51.

[0032] Advantageously, the bottom of the inner wall of the bellows 28 is provided with a groove 42, the flange ring 45 is fixed in the groove 42 by fasteners, and the bag 48 is located in the upper tube 25 and the lower tube 31.

[0033] Advantageously, the backflush structure includes an air pipe 27 fixedly installed inside the air box 28, with multiple nozzles 26 connected to the bottom of the air pipe 27. The nozzles 26 are located above the bag structure. A solenoid valve 34 is connected to one side of the air pipe 27, and a compressed gas tank 35 is connected to the bottom of the solenoid valve 34.

[0034] Advantageously, the nozzle 26 is located above the cloth bag 48.

[0035] When this device is used in a wastewater treatment system, a screw conveyor needs to be connected to the powder valve 11 to transport the lime powder in the tank 13 into the alkaline neutralizing agent solution preparation process.

[0036] The manual flow regulating valve 12 can be manually adjusted to control its opening, and the powder valve 11 can discharge the powder after operation and prevent agglomeration.

[0037] When adding lime powder to the tank 13, start the conveying centrifugal fan 16, pour lime powder into the storage hopper 15, and the lime powder is transported from the input pipe 14 to the tank 13 by the action of the conveying centrifugal fan 16 through the inclined pipe at the bottom of the storage hopper 15.

[0038] After the lime powder and flowing air are mixed, they are injected into the connecting pipe 33 through the input pipe 14. Under the obstruction of the second inclined plate 32 and the first inclined plate 23, the lime powder falls downward into the tank 13 due to gravity and collects. The air flows into the bellows 28 after being blocked by the bag structure and is discharged outward from the outlet pipe 49.

[0039] Since the filter bag 48 is located inside the lower pipe 31 and the upper pipe 25, the lime powder is blocked by the filter bag 48 and prevented from entering the air box 28. The air enters the air box 28 under the filtration effect of the filter bag 48 and is discharged from the outlet pipe 49.

[0040] When backflushing the filter bag 48, the entire equipment stops. Then, after the solenoid valve 34 operates, the compressed air stored in the compressed gas tank 35 is input into the air pipe 27 and sprayed out from the nozzle 26. The compressed air flows from the inside of the filter bag 48 to the outside, blowing the lime powder in the filter bag 48 into the tank 13. The compressed gas tank 35 is also connected to an air compressor in the external space to replenish the compressed gas in the compressed gas tank 35.

[0041] Gas pressure sensor 24 is used to detect the gas pressure inside top tank 21 and tank body 13.

[0042] When personnel disassemble the bag structure, for trachea 27, such as Figure 3 As shown, the air pipe 27 can be installed on one side of the air box 28 using a flange structure. An opening is made in the air box 28, the size of which can accommodate both the air pipe 27 and the nozzle 26. Then, the flange of the air pipe 27 is fixed to one side of the opening to seal it.

[0043] After removing the top cover of the bellows 28, disconnect the air pipe 27 from the bellows 28, and then pull the entire back-blowing structure out from the rear of the bellows 28. After unlocking the fasteners between the flange ring 45 and the groove 42, the bag structure can be removed, and a new bag structure can be installed.

[0044] For the bag structure, a retaining ring 44 is used to press and fix the flange 54 to one side of the flange 53, and the bottom rod 57 is inserted into the bag sleeve 47 to support the bag 48, preventing air from squeezing the bag 48 flat or expanding it too much, thus limiting its shape and size. When disassembling the bag 48 separately, the protruding plate 43 is disassembled from the mounting groove 51, and then the retaining ring 44, the protruding plate 43, and the bottom rod 57 are pulled upwards. Then, the flange 54, the bag sleeve 47, and the bag 48 can be taken out upwards from the groove 42.

[0045] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
