DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-4As shown, the utility model provides a technical solution: a self-cleaning bag filter, including a filter 1, a support frame 2 is installed at the top of the inner part of the filter 1, a filter bag 201 is installed at the outer end of the support frame 2, and a scraper 3 is sleeved on the outer end of the filter bag 201. The shape of the scraper 3 is annular. The support frame 2 can support the filter bag 201, so that the scraper 3 can be easily attached to the surface of the filter bag 201, so that the scraper 3 can scrape and clean the dust on the surface of the filter bag 201. The bottom end of the filter 1 is fixedly connected with The ash collecting box 101 has a discharge pipe 102 fixedly installed at the bottom end of the ash collecting box 101. The dust scraped by the scraper 3 will fall into the ash collecting box 101 and be collected. Then, the dust can be discharged through the discharge pipe 102. A valve is installed in the discharge pipe 102 to facilitate the discharge of dust. The side end of the scraper 3 is fixedly connected to a plurality of side plates 301. The bottom end of each side plate 301 is fixedly connected to a pull rope 302. The tail end of the pull rope 302 extends and is inserted to the outer bottom end of the filter 1. The inner top and inner bottom of the filter 1 are connected to the outer bottom end of the filter 1. A plurality of rebound components for controlling the rebound of the scraper 3 are arranged between them. A winding mechanism for winding the pull rope 302 is arranged at the bottom end of the filter 1. The winding mechanism includes a plurality of rotating components. The plurality of rotating components are arranged at the bottom end of the filter 1. The side ends of two adjacent rotating components are provided with transmission components. The winding and unwinding of the pull rope 302 are realized by the winding mechanism. When the pull rope 302 is wound up, each side plate 301 is pulled downward, which will drive the scraper 3 to move downward. The inner edge of the scraper 3 is attached to the surface of the filter bag 201, so that the lower During the movement, the dust on the surface of the filter bag 201 will be scraped off and fall into the dust collecting box 101 for collection. When the winding mechanism unwinds the pull rope 302, the side plate 301 is moved upward through the setting of the rebound component to drive the scraper 3 to reset, so as to facilitate the next cleaning of the surface of the filter bag 201, so that the filter bag 201 can realize the self-cleaning function and can be automatically cleaned without manual disassembly, thereby improving the cleaning efficiency of the dust on the surface of the filter bag 201 and saving cleaning time.

[0021] As an implementation method in this embodiment, Figure 2 As shown, the rebound component includes a round rod 4, which is fixedly connected between the inner top and the inner bottom of the filter 1. The outer end of the round rod 4 is sleeved with a spring 401, and the side plate 301 is sleeved on the outer end of the round rod 4. When the scraper 3 moves downward, the side plate 301 will press the spring 401 to shrink. When the dust on the outer end of the filter bag 201 is cleaned, the pull rope 302 is unwound by controlling the setting of the winding mechanism, and the spring 401 will also stably push the side plate 301 upward, thereby driving the scraper 3 to move upward, thereby realizing the reset of the scraper 3, which is convenient for cleaning the surface of the filter bag 201 next time.

[0022] As an implementation method in this embodiment, Figure 1 and Figure 4As shown, several rotating components include a limit frame 5, each limit frame 5 is fixedly connected to the bottom end of the filter 1, a rotating rod 501 is rotatably arranged between the two side ends of each limit frame 5, each pull rope 302 is respectively fixedly installed on the outer end of each rotating rod 501, a vertical plate 103 is fixedly installed at the bottom end of the filter 1, and the transmission component includes several sprocket wheels 502, and several sprocket wheels 502 are respectively fixedly connected to the side ends of each rotating rod 501, and several rotating rods 503 are rotatably arranged on the side ends of the vertical plate 103, and the outer ends of each rotating rod 503 are fixedly connected The side ends of the two rotating rods 503 are fixedly connected with a gear 506, and a chain 505 is sleeved between the outer ends of each sprocket 1 502 and each sprocket 2 504. Two adjacent gears 506 are meshed with each other. A motor 507 is fixedly installed on the side end of the vertical plate 103, and the output end of the motor 507 is connected to the side end of one of the two rotating rods 503. In the implementation, the motor 507 is started to drive one of the two rotating rods 503, the two sprockets 504 and the gear 506 to rotate clockwise. At this time, due to the sleeves on the outer ends of the sprockets 1 502 and the sprockets 2 504, the gears 506 are meshed with each other. The chain 505 can simultaneously drive the sprocket 1 502 to rotate clockwise, and at this time, it can drive one of the rotating rods 1 501 to rotate. At this time, when one of the rotating rods 1 501 rotates clockwise, the pull rope 302 at the bottom end of one of the side plates 301 can be pulled and reeled. Since the two adjacent gears 506 are meshed, when one of the gears 506 rotates clockwise, the other gear 506 will rotate counterclockwise. Therefore, since two sets of rotating rods 1 501 are set, one set of rotating rods 1 501 will rotate clockwise to reel one of the pull ropes 302. To reel in the filter bag 201, the other set of rotating rods 501 rotates counterclockwise to reel in the other pull rope 302. At this time, the pull ropes 302 on both sides can be reeled in at the same time. At this time, the pull ropes 302 on both sides pull each side plate 301 downward, which will drive the scraper 3 to move downward. The inner edge of the scraper 3 fits the surface of the filter bag 201. Therefore, the dust on the surface of the filter bag 201 will be scraped off during the downward movement, so that the filter bag 201 can realize the self-cleaning function. It can be automatically cleaned without being manually disassembled, which improves the cleaning efficiency of the dust on the surface of the filter bag 201 and saves cleaning time.

[0023] Working principle: by starting the motor 507, one of the rotating rods 2 503, the sprocket 2 504 and the gear 506 are driven to rotate clockwise. At this time, since the outer ends of the sprocket 1 502 and the sprocket 2 504 are covered with the chain 505, the sprocket 1 502 can be driven to rotate clockwise at the same time, and then one of the rotating rods 1 501 can be driven to rotate. At this time, when one of the rotating rods 1 501 rotates clockwise, the pull rope 302 at the bottom end of one of the side panels 301 can be pulled and reeled. Since the two adjacent gears 506 are meshed, when one of the gears 506 rotates clockwise, the other gear 506 will rotate counterclockwise. Therefore, since two groups of rotating rods 1 501 are set, one group of rotating rods 1 501 will rotate clockwise to reel in one of the pull ropes 302, and the other group of rotating rods 1 501 will rotate counterclockwise to reel in the other pull rope 302. At this time, the pull ropes 302 on both sides can be reeled in at the same time. When the dust on the outer end of the filter bag 201 is cleaned, the side plates 301 will press against the springs 401 to shrink. When the dust on the outer end of the filter bag 201 is cleaned, the motor 507 is started to control the steering of the rotating rod 203, so that each rotating rod 203 can unwind the pull rope 302, and the spring 401 will stably push the side plates 301 to move upward, thereby driving the scraper 3 to move upward, thereby realizing the reset of the scraper 3, facilitating the next cleaning of the surface of the filter bag 201, so that the filter bag 201 can realize the self-cleaning function, and can realize automatic cleaning without being manually disassembled, thereby improving the cleaning efficiency of the dust on the surface of the filter bag 201 and saving cleaning time.

[0024] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
