Description

Technical Field

[0001] This invention relates to the field of baghouse dust collector technology, and more specifically to a self-cleaning industrial baghouse dust collector. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When the dust-laden gas enters the baghouse dust collector, larger, heavier dust particles settle due to gravity and fall into the ash hopper. Gas containing finer dust particles is purified as it passes through the filter media, as the dust is trapped.

[0003] The shortcomings of existing technologies: In existing baghouse dust collectors, dusty air is generally delivered into the housing from one side. The dust in the air then comes into contact with the filter bags, which filter and intercept the dust. The filter bags facing the airflow accumulate more dust first, while the filter bags facing away from the airflow intercept less dust. This makes it impossible to utilize the filter bags evenly. At the same time, excessive dust accumulation on one side of the filter bags over a long period of time, when the dust is thick, is easily hardened by the airflow, making subsequent cleaning more difficult and less effective. This also reduces the service life of the filter bags. To address these issues, we propose a self-cleaning industrial baghouse dust collector. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a self-cleaning industrial bag filter to solve the problems existing in the background art.

[0005] This invention provides the following technical solution: a self-cleaning industrial bag filter dust collector, comprising a dust hopper, a housing installed at the upper end of the dust hopper, a cover plate installed at the upper end of the housing, a perforated plate installed inside the housing, and a dust removal assembly disposed within the perforated plate. The dust removal assembly includes rotating rings, a bag filter element, and a frame. Multiple rotating rings are rotatably connected within the perforated plate, and the bag filter element and the frame are installed within the rotating rings. The frame is located within the bag filter element. A cleaning assembly is installed at the lower end of the perforated plate. The cleaning assembly includes a guide frame, a lifting shell, rotating rods, and soft brushes. Multiple sets of guide frames are installed at the lower end of the perforated plate. The lifting shells are slidably connected to the circumferential surface of the guide frames. Each set of lifting shells is connected to the other via a connecting rod. Multiple rotating rods are rotatably connected within the lifting shells. Soft brushes are installed on the circumferential surface of the rotating rods. Connecting gears are installed on the circumferential surface of the rotating rods, and the connecting gears mesh with tooth grooves opened on the circumferential surface of the guide frames.

[0006] Preferably, a connecting shaft is rotatably connected to the lower end of the perforated plate, a take-up roller is mounted on the circumferential surface of the connecting shaft, a steel wire is mounted on the circumferential surface of the take-up roller, a lifting frame is mounted on the end of the steel wire away from the take-up roller, the lifting shell is fixedly connected to the lifting frame, and a tension spring is installed between the guide frame and the lifting shell.

[0007] Preferably, a drive motor is installed at the rear end of the housing, and a drive shaft is installed at the output end of the drive motor. The drive shaft and the connecting shaft are connected by a sprocket assembly.

[0008] Preferably, a pair of rotating shafts are rotatably connected to the upper end of the perforated plate, and multiple worm gears are installed on the circumferential surface of each rotating shaft. Worm wheels are installed on the circumferential surface of each rotating ring, and the worm wheels mesh with the worm gears.

[0009] Preferably, a pair of driven shafts are rotatably connected to the lower end of the perforated plate, and a one-way sprocket is mounted on the circumferential surface of the driven shaft. The drive sprocket mounted on the circumferential surface of the drive shaft is connected to the one-way sprocket by a chain. A rotating shaft is rotatably connected inside the perforated plate. The lower end of the rotating shaft is connected to the driven shaft by a first sector gear set, and the upper end of the rotating shaft is connected to the rotating shaft by a second sector gear set.

[0010] Preferably, a pulse assembly is installed on the surface of the housing. The pulse assembly includes a gas tank, a diverter pipe, a connecting pipe, and a jet pipe. The gas tank is installed on the surface of the housing, and multiple diverter pipes are installed on the gas tank. Each connecting pipe is connected to a diverter pipe via a rotating joint. Multiple rotating seats are installed on the inner wall of the housing. The end of the diverter pipe away from the rotating joint is located inside the rotating seat, and multiple jet pipes are installed on the connecting pipe.

[0011] Preferably, a telescopic cylinder is installed on the circumferential surface of the diverter pipe, a limit rod is slidably connected inside the telescopic cylinder, a spring is installed between the limit rod and the telescopic cylinder, a plurality of positioning seats are installed on the upper end of the orifice plate, and the lower end of the limit rod is located inside the positioning seat.

[0012] Preferably, an air inlet pipe is installed at the left end of the box, an exhaust pipe is installed at the right end of the box, and a dust discharge component is provided at the lower end of the ash hopper.

[0013] The technical effects and advantages of this invention are as follows:

[0014] This invention uses a filter bag to filter and intercept dust in the air. By controlling the rotation of the filter bag, the surface of the filter bag is made to contact the dust evenly, preventing one side of the filter bag from being affected by airflow and accumulating too much dust. At the same time, the lifting shell is controlled to slide up and down on the circumference of the guide frame, so that the soft brush in the lifting shell moves up and down synchronously with the lifting shell. The rotating soft brush contacts the filter bag and evenly sweeps the dust on the surface of the filter bag, so that a large amount of dust is dispersed in the box, slowing down the rate at which dust is adsorbed on the surface of the filter bag. At the same time, it avoids the bottom of the filter bag from accumulating too much dust first, achieving the effect of uniform dust absorption by the entire filter bag.

[0015] This invention allows the limiting rod to be pulled out of the positioning seat, and then the diversion tube can be rotated between the rotating joint and the rotating seat, so that the diversion tube rotates to the side of the frame and the filter element. Then the frame and the filter element can be directly pulled out of the perforated plate for replacement. When replacing the filter element, it is not necessary to disassemble the diversion tube above the filter element, thus achieving the effect of fast and efficient replacement of the filter element.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The self-cleaning industrial bag dust collector involved in the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1-10As shown, in one embodiment, a self-cleaning industrial bag filter dust collector is proposed, including a dust hopper 1, a housing 101 installed at the upper end of the dust hopper 1, a cover plate 102 installed at the upper end of the housing 101, a perforated plate 103 installed inside the housing 101, and a dust collection assembly 2 disposed inside the perforated plate 103. The dust collection assembly 2 includes rotating rings 201, a bag filter element 202, and a frame 203. Multiple rotating rings 201 are rotatably connected within the perforated plate 103. The bag filter element 202 and the frame 203 are both installed within the rotating rings 201, with the frame 203 located within the bag filter element 202. A cleaning assembly is installed at the lower end of the perforated plate 103. Component 3, the cleaning assembly 3 includes a guide frame 301, a lifting shell 302, a rotating rod 304, and a soft brush 305. Multiple sets of guide frames 301 are installed at the lower end of the perforated plate 103. The lifting shells 302 are slidably connected to the circumferential surface of the guide frames 301. Each set of lifting shells 302 is connected to each other by a connecting rod 303. Multiple rotating rods 304 are rotatably connected inside the lifting shells 302. The soft brushes 305 are all installed on the circumferential surface of the rotating rods 304. A connecting gear 306 is installed on the circumferential surface of the rotating rods 304. The connecting gear 306 meshes with the toothed grooves 307 opened on the circumferential surface of the guide frame 301.

[0032] In practical application, when dusty air is delivered into the housing 101, the bag filter element 202 filters and intercepts the dust. The air is then discharged after passing through the bag filter element 202. During dust filtration, controlling the rotation of the rotating ring 201 causes the bag filter element 202 and frame 203 to rotate, ensuring the surface of the bag filter element 202 is evenly exposed to the dust, preventing a large amount of dust from accumulating on one side. This ensures the bag filter element 202 absorbs dust evenly. Simultaneously, controlling the lifting shell 302 to slide up and down on the circumferential surface of the guide frame 301 causes the lifting shell 302 to slide through the toothed grooves 307 on the circumferential surface of the guide frame 301, which in turn drives the connecting gear 306 to rotate. The connecting gear 306 then drives the rotating rod 304 and the soft brush 305 to rotate. As the lifting housing 302 moves up and down synchronously, the rotating soft brush 305 comes into contact with the bag filter element 202, evenly sweeping away the dust on the surface of the bag filter element 202. This causes a large amount of dust to diffuse into the housing 101, slowing down the rate at which dust is adsorbed on the surface of the bag filter element 202. Since air is generally transported from bottom to top, this avoids excessive dust accumulation at the bottom of the bag filter element 202 first, achieving the effect of even dust absorption by the entire bag filter element 202. When the dust content in the housing 101 is high, the lifting housing 302 can be stopped from moving up and down, allowing the surface of the bag filter element 202 to quickly absorb dust. The dust quickly adheres to the surface of the bag filter element 202 in a short time, which not only improves the utilization rate of the bag filter element 202, but also makes it easier to clean the dust on the bag filter element 202.

[0033] like Figure 3-6As shown, in one embodiment, a connecting shaft 4 is rotatably connected to the lower end of the perforated plate 103. A take-up roller 401 is mounted on the circumferential surface of the connecting shaft 4. A steel wire 402 is mounted on the circumferential surface of the take-up roller 401. A lifting frame 403 is mounted on the end of the steel wire 402 away from the take-up roller 401. The lifting shell 302 is fixedly connected to the lifting frame 403. A tension spring 404 is installed between the guide frame 301 and the lifting shell 302.

[0034] In practical application, the connecting shaft 4 is controlled to rotate in both directions, synchronously driving the take-up roller 401 to rotate in both directions, achieving the effect of simultaneously winding and unwinding four steel wires 402. When the steel wires 402 are wound, the lifting frame 403 can be driven to move upward, and the lifting frame 403 drives multiple lifting shells 302 to move upward synchronously, thereby controlling the soft brush 305 to move upward. When the steel wires 402 are unwound, through the action of the tension spring 404, and through the cooperation of the weight of the multiple lifting shells 302 and the lifting frame 403, the lifting frame 403 and the multiple lifting shells 302 can be moved downward synchronously, thereby controlling the soft brush 305 to move downward. By rotating the connecting shaft 4 in both directions, the lifting shells 302 and the brush can be controlled to move up and down on the circumferential surface of the guide frame 301, cleaning the dust on the bag filter element 202, and preventing excessive dust from adsorbing on the surface of the bag filter element 202, which would affect the air permeability of the bag filter element 202.

[0035] like Figure 1 and 6 As shown, in one embodiment, a drive motor 405 is installed at the rear end of the housing 101, and a drive shaft 406 is installed at the output end of the drive motor 405. The drive shaft 406 and the connecting shaft 4 are connected by a sprocket set 407.

[0036] In practical application, the drive motor 405 is controlled to operate. Through the action of the sprocket set 407, the drive motor 405 can drive a pair of connecting shafts 4 to rotate. When the lifting shell 302 moves to the uppermost or lowermost limit position of the guide frame 301, the drive motor 405 adjusts the rotation direction, thereby achieving the effect of controlling the soft brush 305 to move up and down reciprocally.

[0037] like Figure 2-4 As shown, in one embodiment, a pair of rotating shafts 5 are rotatably connected to the upper end of the orifice plate 103. Multiple worm gears 501 are installed on the circumferential surface of each rotating shaft 5, and worm wheels 502 are installed on the circumferential surface of each rotating ring 201. The worm wheels 502 mesh with the worm gears 501.

[0038] In practical application, the rotating shaft 5 is controlled to rotate, which in turn drives multiple worm gears 501 to rotate. The worm gears 501 drive the worm wheel 502 to rotate, and the worm wheel 502 drives the rotating ring 201 to rotate, thereby achieving the effect of controlling the rotation of the frame 203 and the bag filter element 202.

[0039] like Figure 4 and 6 As shown, in one embodiment, a pair of driven shafts 503 are rotatably connected to the lower end of the perforated plate 103. A one-way sprocket 504 is mounted on the circumferential surface of the driven shaft 503. The drive sprocket 505 mounted on the circumferential surface of the drive shaft 406 is connected to the one-way sprocket 504 by a chain 506. A rotating shaft 507 is rotatably connected inside the perforated plate 103. The lower end of the rotating shaft 507 is connected to the driven shaft 503 by a first sector gear set 508. The upper end of the rotating shaft 507 is connected to the rotating shaft 503 by a second sector gear set 509.

[0040] In practical application, when the drive motor 405 drives the drive shaft 406 to rotate, when the drive motor 405 rotates forward, it can drive the driven shaft 503 to rotate through the action of the drive sprocket 505, chain 506, and one-way sprocket 504. Due to the one-way rotation characteristic of the one-way sprocket 504, when the drive motor 405 rotates in the opposite direction, the one-way sprocket 504 will idle and will not drive the driven shaft 503 to rotate. When the driven shaft 503 rotates, it drives the rotating shaft 507 to rotate through the action of the first sector gear set 508. 07 Then, through the action of the second sector gear set 509, the rotating shaft 5 is driven to rotate. When the rotating shaft 5 rotates, the rotating ring 201 and the bag filter element 202 are driven to rotate through the action of the worm 501 and the worm wheel 502. Since the drive motor 405 drives the shaft 406 to switch the rotation direction back and forth to control the soft brush 305 to move up and down, the rotating ring 201 and the bag filter element 202 can be rotated intermittently in one direction, so as to adjust the airflow direction of the bag filter element 202. At the same time, the soft brush 305 can be evenly contacted with the surface of the bag filter element 202.

[0041] like Figure 2 and 11 As shown, in one embodiment, a pulse assembly 6 is installed on the surface of the housing 101. The pulse assembly 6 includes a gas tank 601, a diverter pipe 602, a connecting pipe 603, and a jet pipe 606. The gas tank 601 is installed on the surface of the housing 101, and multiple diverter pipes 602 are installed on the gas tank 601. The connecting pipes 603 are all connected to the diverter pipes 602 through a rotating joint 604. Multiple rotating seats 605 are installed on the inner wall of the housing 101. The end of the diverter pipe 602 away from the rotating joint 604 is located inside the rotating seat 605. Multiple jet pipes 606 are all installed on the connecting pipe 603.

[0042] In practical application, the pulsed gas is controlled to be output from the diverter 602, then transported to the connecting pipe 603 through the rotary joint 604, and then blown out through the jet pipe 606, so that the pulsed gas flow blows into the bag filter element 202 below the corresponding position, causing the bag filter element 202 to expand and vibrate violently in a very short time. The instantaneous expansion and vibration of the bag filter element 202 causes the dust layer attached to its outer surface to break and fall off, and finally fall into the ash hopper 1.

[0043] like Figure 11-13 As shown, in one embodiment, telescopic cylinders 607 are installed on the circumferential surface of the diversion pipe 602. A limit rod 608 is slidably connected inside the telescopic cylinder 607. A spring 609 is installed between the limit rod 608 and the telescopic cylinder 607. Multiple positioning seats 6010 are installed on the upper end of the orifice plate 103. The lower end of the limit rod 608 is located inside the positioning seat 6010.

[0044] In practical applications of this invention, since the bag filter element 202 is a consumable, it needs to be replaced after a period of use to ensure the effectiveness of the dust removal equipment. When the bag filter element 202 needs to be replaced, such as... Figure 13 As shown, by lifting the limiting rod 608 upwards, the limiting rod 608 is pulled out of the positioning seat 6010. Then, the diversion tube 602 can be rotated between the rotating joint 604 and the rotating seat 605, so that the diversion tube 602 rotates to one side of the frame 203 and the bag filter element 202. Then, the frame 203 and the bag filter element 202 can be directly pulled out from the orifice plate 103 for replacement. After the replacement is completed, the diversion tube 602 is rotated back to its original position, and then the limiting rod 608 is reinserted into the positioning seat 6010 to restrict the position of the diversion tube 602, ensuring that the jet pipe 606 is directly facing the bag filter element 202 below. When replacing the bag filter element 202, it is not necessary to disassemble the diversion tube 602 above the bag filter element 202, so as to achieve the effect of quick and efficient replacement of the bag filter element 202.

[0045] like Figure 1 As shown, in one embodiment, an air inlet pipe 104 is installed at the left end of the housing 101, an exhaust pipe 105 is installed at the right end of the housing 101, and a dust discharge assembly 106 is provided at the lower end of the ash hopper 1.

[0046] In practical application, the present invention delivers gas into the housing 101 through the air inlet pipe 104. Dust in the air is intercepted by the bag filter element 202, and the air is then discharged through the exhaust pipe 105. When cleaning the dust on the bag filter element 202, the gas discharge is stopped. Finally, the dust falls into the dust hopper 1 through the action of the pulse component 6, and is discharged through the dust discharge component 106.

[0047] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
