[0002] A bag type dust collector is a common dry dust filtering device, which is suitable for collecting fine, dry non-fibrous dust; the bag type dust collector includes filter bags and a hopper arranged below the filter bags. The filter bags are the key components, and the filter bags are usually made of woven filter cloth or non-woven felt cloth, so as to filter the dust-containing gas by the filtering action of its fiber structure; when the dust-containing gas enters the bag type dust collector, the dust with large particles and high specific gravity settles into the hopper under the action of gravity, and the fine dust in the dust-containing gas is retained by the filter bags, so that the gas is purified.

[0003] With the long-term use of the filter bags, more and more dust will adhere to the surface of the filter bags, resulting in a decrease in their air permeability efficiency and a deterioration of the filtering effect; in order to ensure the filtering effect of the dust collector, the traditional treatment method is to open the dust collector to clean or replace the filter bags. This treatment method is relatively complex in operation, slow in treatment speed and low in efficiency, and requires long-term shutdown operation; therefore, in view of the above problems, improvements are needed now.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) This bag - type dust removal device has an internal and external double - cleaning structure. The internal cleaning structure quickly and repeatedly supports the inside of the filter bag through reciprocating telescopic operation, causing the filter bag to be repeatedly tightened, so that the dust attached to the surface of the filter bag automatically falls off. The external cleaning structure further cleans the surface of the filter bag by lifting and rotating the cleaning components. Thus, the quality of dust cleaning on the surface of the filter bag is effectively guaranteed. Through the internal and external double - cleaning structure, the speed and efficiency of dust cleaning on the surface of the filter bag can be effectively improved, and the performance of the bag - type dust removal device is improved. At the same time, the structure of this bag - type dust removal device is simply designed, convenient to use, the cleaning operation is stable and reliable, and its performance can meet the dust removal use requirements;

[0018] (2) When the adjusting rod rotates, through the sleeve and the L - shaped rod, the four stretching rods and the two adjusting sleeves will not rotate with the adjusting rod. The rotation of the adjusting rod drives the two inclined circular grooves to rotate. The rotation of the two inclined circular grooves drives the toggle pins to reciprocate inside them. The reciprocating movement of the toggle pins inside the inclined circular grooves drives the two adjusting sleeves to reciprocate relative to or away from each other on the surface of the adjusting rod. The two adjusting sleeves moving relatively will push the stretching rods towards the filter bag through the extension rods, so that the four stretching rods support and tighten the filter bag, and the dust attached to the surface of the filter bag automatically falls off. The two adjusting sleeves moving away from each other will pull the stretching rods away from the filter bag through the extension rods. And through the reciprocating movement of the four stretching rods to support and tighten the filter bag, the dust attached to the surface of the filter bag can be cleaned and automatically fall off, and the dust automatically falls into the ash hopper;

[0019] (3) When the transmission shaft needs to be disassembled, first move the sleeve upward to compress the corrugated pipe and spring B, so that the upper part of the transmission shaft moves out of the inside of the sleeve, and at the same time, the square groove is exposed. Then, tilt the transmission shaft to make the square insert B move out of the inside of the square groove. Then, tilt and lift the transmission shaft upward to make the square insert A move out of the inside of the square slot, and then the transmission shaft can be disassembled. After the transmission shaft is disassembled, the square frame, the stretching mechanism and the filter bag can be disassembled and replaced;

[0020] (4) By starting motor A, one of the sprocket bodies rotates. The rotation of one of the sprocket bodies drives all the sprocket bodies to rotate through the chain body. The rotation of all the sprocket bodies drives all the adjusting shafts to rotate. The rotation of the adjusting shaft drives the transmission shaft to rotate through the square groove and the square insert B. The rotation of the transmission shaft drives the adjusting rod to rotate and adjust through the square insert A and the square slot;

[0021] (5) Rotate one of the rotating shafts by starting motor B. At the same time, the two meshed gears will cause the two rotating shafts to rotate synchronously relative to each other. The two rotating shafts rotating synchronously relative to each other will cause the rotating arms to rotate downward. The two downward-rotating rotating shafts will drive the moving sleeve to slide on the surface of the n-shaped slide bar and move relatively, and drive the lifting plate to move downward through the two n-shaped slide bars for adjustment.

[0022] (6) When the lifting plate moves downward, it will drive the transmission gear to move downward, causing the transmission gear to roll and rotate on the surface of the rack. The rotation of the transmission gear will drive the worm to rotate. The rotation of the worm will drive the worm gear ring meshed with it to rotate. The rotation of the worm gear ring will drive the rotating ring, connecting sleeve and fixed sleeve to rotate, enabling the rotating ring to rotate stably inside the ring groove for adjustment. The rotation of the fixed sleeve will drive the cleaning brush and gear to rotate. The rotation of the gear will rotate on the internal gear ring and drive the cleaning brush to rotate self. Finally, the downward movement of the lifting plate will cause the cleaning brush to move downward. During the downward movement, the cleaning brush will rotate around the filter bag and rotate self, so as to comprehensively clean the surface of the filter bag. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the structure of this bag-type dust removal device is simply designed, easy to use, the cleaning operation is stable and reliable, and its performance can meet the dust removal use requirements.

[0039] Embodiment 2, on the basis of Embodiment 1, the stretching mechanism includes a cross-shaped holder 21. Four grooves 22 are equidistantly arranged in a ring at the top of the square frame 14. The four corners of the cross-shaped holder 21 are clamped inside the four grooves 22. A regulating rod 23 is rotatably connected to the middle of the cross-shaped holder 21. The regulating rod 23 passes through the support frame 1401 and extends into the interior of the filter bag 13. Two regulating sleeves 24 are movably sleeved on the surface of the regulating rod 23. Four stretching rods 25 are rotatably connected to the surfaces of the two regulating sleeves 24 at equal intervals in a ring. A stretching rod 26 is movably connected between two opposite stretching rods 25 on the two regulating sleeves 24. L-shaped rods 28 are fixedly installed on the upper parts of the four stretching rods 26. The tops of the four L-shaped rods 28 are fixedly connected with sleeves 27. The four sleeves 27 are respectively movably sleeved on the four sides of the cross-shaped holder 21.

[0040] Two shifting pins 29 are fixedly connected inside the two regulating sleeves 24. The two shifting pins 29 are symmetrically arranged. Two inclined annular grooves 30 are symmetrically formed on the surface of the regulating rod 23. One ends of the two shifting pins 29 are respectively located inside the two inclined annular grooves 30. A stop block 31 is fixedly installed on the surface of the regulating rod 23. The stop block 31 is symmetrically arranged on the surface of the regulating rod 23 through the two regulating sleeves 24. Two spring A32 and two movable annular plates 33 are symmetrically sleeved on the surface of the regulating rod 23 through the stop block 31. The relative ends of the two spring A32 are fixedly connected with the stop block 31. The opposite ends of the two spring A32 are respectively fixedly connected with the two movable annular plates 33. The movable annular plate 33 is located between the regulating sleeve 24 and the spring A32, so as to effectively perform rapid and repeated telescopic adjustment on the four stretching rods 26, so that the four stretching rods 26 tighten the filter bag 13, and the dust attached to the surface of the filter bag 13 automatically falls off.

[0041] Specifically, when the regulating rod 23 rotates, the four stretching rods 26 and the two regulating sleeves 24 will not rotate with the regulating rod 23 through the sleeves 27 and the L-shaped rods 28. The rotation of the regulating rod 23 will drive the two inclined annular grooves 30 to rotate. The rotation of the two inclined annular grooves 30 will drive the shifting pins 29 to reciprocate inside them. The reciprocating movement of the shifting pins 29 inside the inclined annular grooves 30 will drive the two regulating sleeves 24 to reciprocate relatively or away from each other on the surface of the regulating rod 23. The two relatively moving regulating sleeves 24 will push the stretching rods 26 towards the filter bag 13 through the stretching rods 25, so that the four stretching rods 26 support and tighten the filter bag 13, and the dust attached to the surface of the filter bag 13 automatically falls off. The two regulating sleeves 24 moving away from each other will pull the stretching rods 26 away from the filter bag 13 through the stretching rods 25. The reciprocating movement of the four stretching rods 26 to support and tighten the filter bag 13 will cause the dust attached to the surface of the filter bag 13 to be automatically cleaned and fall off, and the dust will automatically fall into the ash hopper 2.

[0042] The two adjustment sleeves 24 that move relative to each other will compress the spring A32 through the movable ring plate 33, and then the elastic force of the spring A32 will enable the two adjustment sleeves 24 to effectively move away from each other for adjustment.

[0043] A square slot 34 is provided at the top of the adjusting rod 23, and a square plug A35 and a square plug B36 are fixedly installed at the bottom and the middle of the top of the transmission shaft 16 respectively, and the square plug A35 is inserted into the inside of the square slot 34; an adjusting shaft 37 that penetrates the fixed plate 15 is rotatably installed on the fixed plate 15 at equal intervals, and a square groove 38 is provided at the bottom of the adjusting shaft 37, and the square plug B36 is movably engaged in the inside of the square groove 38, and the surface of the adjusting shaft 37 located below the fixed plate 15 is fixedly connected with a bellows 39 and a spring B40, and the surface of the adjusting shaft 37 located below the fixed plate 15 is movably sleeved with a sleeve 41, and the bottoms of the bellows 39 and the spring B40 are fixedly connected to the sleeve 41, and the upper part of the transmission shaft 16 is located inside the sleeve 41, so that the transmission shaft 16 can be effectively disassembled and assembled, and the square frame 14 and the filter bag 13 can be conveniently disassembled and assembled, and the transmission can be effectively performed.

[0044] Specifically, when the transmission shaft 16 needs to be disassembled, the sleeve 41 is first moved upward to compress the bellows 39 and the spring B40, so that the upper part of the transmission shaft 16 is moved out from the inside of the sleeve 41, and the square groove 38 is leaked out at the same time. Then, the transmission shaft 16 is tilted to move the square plug B36 out from the inside of the square groove 38, and then the transmission shaft 16 is tilted and lifted upward to move the square plug A35 out from the inside of the square slot 34, and the transmission shaft 16 can be disassembled.

[0045] After the transmission shaft 16 is disassembled, the square frame 14, the support mechanism and the filter bag 13 can be disassembled and replaced;

[0046] During installation, the transmission shaft 16 is tilted, and the sleeve 41 is moved up at the same time, and the square plug A35 is aligned with the square slot 34, and then the transmission shaft 16 is pushed to make it vertical. The verticality of the transmission shaft 16 will drive the square plug B36 to be inserted into the inside of the square groove 38, and then the sleeve 41 is released. Through the elastic force of the bellows 39 and the spring B40, the sleeve 41 will be sleeved on the upper part of the transmission shaft 16, and the transmission shaft 16 is stably installed.

[0047] The transmission structure based on the chain and sprocket includes a sprocket body 42 fixedly installed on the top of the adjusting shaft 37, and a chain body 43 is installed between the sprocket bodies 42 on the top of all the adjusting shafts 37.

[0048] Specifically, by starting the motor A17, one of the sprocket bodies 42 is rotated. The rotation of one of the sprocket bodies 42 will cause all the sprocket bodies 42 to rotate through the chain body 43. The rotation of all the sprocket bodies 42 will drive all the adjusting shafts 37 to rotate. The rotation of the adjusting shaft 37 will drive the transmission shaft 16 to rotate through the square groove 38 and the square insert block B36. The rotation of the transmission shaft 16 will drive the adjusting rod 23 to rotate and adjust through the square insert block A35 and the square slot 34.

One end of each of the four rotating arms 46 is rotatably connected to the top of each of the four moving sleeves 48, so as to effectively adjust the lifting of the lifting plate 18.

[0050] Specifically, by starting the motor B20, one of the rotating shafts 44 is rotated. At the same time, the two rotating shafts 44 will rotate synchronously and relatively through the two engaged gears 45. The two rotating shafts 44 rotating synchronously and relatively will cause the rotating arms 46 to rotate downward. The two rotating shafts 44 rotating downward will drive the moving sleeves 48 to slide and move relatively on the surfaces of the n-shaped sliding rods 47, and drive the lifting plate 18 to move downward through the two n-shaped sliding rods 47 for adjustment.

The transmission gear 60 is located inside the vertical groove 61 and is meshed and connected with the rack 62, so as to be able to clean the dust on the surface of the filter bag 13.

[0053] When the lifting plate 18 moves downward, it will drive the transmission gear 60 to move downward, causing the transmission gear 60 to roll and rotate on the surface of the rack 62. The rotation of the transmission gear 60 will drive the worm gear 58 to rotate. The rotation of the worm gear 58 will drive the worm gear ring 57 meshed with it to rotate. The rotation of the worm gear ring 57 will drive the rotating ring 50, the connecting sleeve 51 and the fixed sleeve 52 to rotate, so that the rotating ring 50 can stably rotate and adjust inside the circular groove 49. The rotation of the fixed sleeve 52 will drive the cleaning brush 53 and the gear 54 to rotate. The rotation of the gear 54 will rotate on the internal gear ring 56 and drive the cleaning brush 53 to rotate self - rotatably.

[0054] Finally, the downward movement of the lifting plate 18 causes the cleaning brush 53 to move downward. During the downward movement of the cleaning brush 53, it will rotate around the filter bag 13 and rotate self - rotatably, so that the cleaning brush 53 can comprehensively clean the surface of the filter bag 13.
