Description

Technical Field

[0001] This utility model relates to the technical field of bag filter equipment, specifically a self-cleaning dust filter bag device. Background Technology

[0002] A bag filter 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 dust-laden gas enters the bag filter, larger and heavier dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter material, the dust is trapped, thus purifying the gas.

[0003] Publication No. CN221358974U discloses a bag filter structure. This device achieves dust collection by setting up a motor body, baffles, and a dust discharge port. Dust-laden gas enters the housing through the inlet pipe and is filtered by the filter bag body before being discharged through the exhaust pipe. Some dust falls onto the upper part of the fixed plate. The motor body intermittently drives the turntable to rotate, thereby scraping and cleaning the upper part of the baffle and the upper part of the fixed plate by the first and second scrapers, respectively. This allows the dust to be discharged through the dust discharge port into the dust discharge pipe, avoiding direct communication between the housing and the dust discharge port. This ensures that the dust-laden airflow entering the housing does not affect the dust hopper and prevents secondary dust generation from the dust already deposited in the dust hopper, thus improving dust collection efficiency. However, this patent still has the following problems in actual use:

[0004] This device achieves dust collection by setting up a motor body, baffles, and ash discharge port. Dust-laden gas enters the housing through the air inlet pipe and is discharged through the exhaust pipe after being filtered by the filter bag body. However, this device does not have the function of cleaning the filter bag, which means that the staff need to clean the larger impurities attached to the surface of the filter bag frequently, which greatly reduces the flexibility and efficiency of the device during use.

[0005] A self-cleaning dust filter bag device is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a self-cleaning dust collection filter bag device to solve the problem mentioned in the background art. Currently, the device achieves the effect of collecting dust by setting up a motor body, baffle and ash discharge port. The dust-laden gas enters the shell through the air inlet pipe and is discharged through the exhaust pipe after being filtered by the filter bag body. However, this device does not have the effect of cleaning the filter bag, which leads to the need for workers to frequently clean the larger impurities attached to the surface of the filter bag.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a self-cleaning dust removal filter bag device, comprising a housing, an air inlet pipe fixedly installed on one side of the bottom of the housing, an exhaust pipe fixedly installed on one side of the top of the housing, an end cap inserted into the upper interior of the housing, and a discharge pipe fixedly installed in the lower interior of the housing; a filtration mechanism is provided inside the housing, and fixing components are provided between the housing and the end cap.

[0008] The filtration mechanism includes a fixed plate fixedly installed inside the housing, with a cylindrical frame inserted inside the fixed plate. A filter bag body is sleeved on the bottom outer side of the cylindrical frame. A support frame is fixedly installed on the bottom side inside the housing. A cleaning plate is arranged between the cylindrical frames. An annular brush plate is embedded inside the cleaning plate. Strip boxes are symmetrically fixedly installed on both sides inside the housing. A fixed box is fixedly installed at the bottom of the strip box. A drive rod is rotatably connected between the fixed box and the housing. A forward and reverse motor is fixedly installed at one end of the drive rod. A screw is rotatably connected between the strip box and the fixed box. A lifting rod is threaded onto the outside of the screw. The top of the lifting rod is fixedly connected to the bottom of the cleaning plate.

[0009] Preferably, a first conical tooth is fixedly installed at the bottom of the screw, and a second conical tooth is symmetrically fixedly installed on the outside of the drive rod, and the first conical tooth and the second conical tooth are meshed together.

[0010] Preferably, the cleaning plate has symmetrically slidably connected support rods on both sides, with the bottom of the support rods fixedly connected to the support frame, and the top of the support rods penetrating through the fixed plate and slidably connected to the fixed plate.

[0011] Preferably, the fixing component includes a limiting box, and the limiting boxes are symmetrically fixedly installed inside the end cover. Slots are symmetrically opened on the top outer side of the housing. A threaded tube is fixedly installed inside the limiting box, and a threaded rod is threadedly connected inside the threaded tube. A push plate is rotatably connected to one end of the threaded rod. An insert plate is welded to the side of the push plate away from the threaded rod, and the insert plate is inserted into the slot. A retractable rod is symmetrically fixedly installed between the inner side of the limiting box and the push plate, and a retractable spring is sleeved on the outside of the retractable rod.

[0012] Preferably, the cleaning plate has slots inside, and a heat dissipation box is fixedly installed at the end of the housing near the forward and reverse motors, and a block is inserted into the lower interior of the discharge pipe.

[0013] Preferably, the outer side of the tube frame is in contact with the inner side of the annular brush plate.

[0014] Preferably, the outside of the lifting rod is slidably connected to the inside of the strip box.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The self-cleaning dust removal filter bag device is specifically described as follows: A forward and reverse motor drives the rotation of the drive rod, the rotation of the second conical tooth drives the rotation of the first conical tooth, and the rotation of the screw drives the lifting rod to slide longitudinally inside the strip box. Thus, the two sets of lifting rods move up and down synchronously, driving the cleaning plate to move. At this time, the brush bristles evenly sweep away the accumulated impurities on the outside of the filter bag body, thereby achieving a rapid initial cleaning effect on the external impurities of the filter bag body. This effectively reduces the phenomenon of dust accumulation on the surface of the filter bag body causing poor filtration, and also effectively reduces the number of times workers need to clean and maintain the filter bag body, improving the service life and efficiency of the filtration device. Multiple sets of threaded rods rotate inside the threaded tube, and the rotation of the threaded rods drives the push plate to slide inside the limit box. At this time, the insert plate and the slot are inserted, thereby achieving the effect of quick installation and removal of the end cover. This facilitates subsequent inspection and maintenance of the internal filtration structure of the housing by workers, greatly improving the daily maintenance efficiency of the device.

[0016] 1. The worker places the filter bag body onto the outside of the cylinder frame and positions it using strapping. Then, the worker evenly inserts multiple cylinder frames into the pre-drilled slots inside the fixing plate. At this point, the worker inserts the end caps into the top of the housing, where the bottom of the end caps presses against the top of the cylinder frame to limit movement. When it is necessary to clean impurities adhering to the outside of the filter bag body, the worker starts the forward and reverse motors to rotate the drive rod. The rotation of the drive rod drives the rotation of two sets of second conical teeth, which in turn drives the rotation of the first conical teeth. The rotation of the first conical teeth drives the rotation of the screw, which in turn causes the lifting rod to slide longitudinally inside the strip box, thus synchronizing the two sets of lifting rods. The up-and-down movement of the cleaning plate causes it to move, which in turn drives multiple sets of annular brush plates to clean the exterior of the filter bag. The brush bristles evenly sweep away the accumulated impurities on the exterior of the filter bag, thus achieving a rapid initial cleaning effect on the exterior of the filter bag. This effectively reduces the phenomenon of dust accumulation on the surface of the filter bag, which can lead to poor filtration. It also effectively reduces the number of times staff need to clean and maintain the filter bag, improving the service life and efficiency of the filtration device. The cleaning plate slides outside the four support rods, making its movement more stable. The slot design effectively reduces the accumulation of dust and impurities on the top of the cleaning plate.

[0017] 2. The staff inserts the end cap into the top of the housing. At this time, the rubber plate at the bottom of the end cap is pressed against the inside of the housing. The staff then rotates multiple sets of threaded rods inside the threaded tube. The rotation of the threaded rods causes the push plate to slide inside the limit box. At this time, the insert plate and the slot are inserted, which can achieve the effect of quick installation and removal of the end cap. This facilitates the staff to inspect and maintain the internal filter structure of the housing, greatly improving the efficiency of daily maintenance of the device and increasing the flexibility and efficiency of the device during use.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7The present invention provides a technical solution: a self-cleaning dust removal filter bag device, comprising a housing 1, an air inlet pipe 101 fixedly installed on one side of the bottom of the housing 1, an exhaust pipe 102 fixedly installed on one side of the top of the housing 1, an end cap 103 inserted into the upper interior of the housing 1, and a discharge pipe 104 fixedly installed in the lower interior of the housing 1; a filter mechanism 2 is provided inside the housing 1, and a fixing component 3 is provided between the housing 1 and the end cap 103;

[0028] The filtration mechanism 2 includes a fixed plate 201 fixedly installed inside the housing 1, with a cylindrical frame 202 inserted inside each fixed plate 201. A filter bag body 203 is sleeved on the bottom outer side of the cylindrical frame 202. A support frame 204 is fixedly installed on the bottom side inside the housing 1. A cleaning plate 205 is provided between the outer sides of the cylindrical frame 202, and an annular brush plate 206 is embedded inside each cleaning plate 205. The outer side of the cylindrical frame 202 fits against the inner side of the annular brush plate 206. A strip box 207 is symmetrically fixedly installed on both sides inside the housing 1, and a fixed box 208 is fixedly installed at the bottom of the strip box 207. A drive rod 209 is rotatably connected between the fixed box 208 and the housing 1. A forward and reverse motor 210 is fixedly installed at one end of the drive rod 209. The strip box 207 and the fixed box 208 are rotatably connected to the housing 1. A screw 211 is rotatably connected between the fixed boxes 208, and a lifting rod 212 is threadedly connected to the outside of the screw 211. The outside of the lifting rod 212 is slidably connected to the inside of the strip box 207, and the top of the lifting rod 212 is fixedly connected to the bottom of the cleaning plate 205. A first conical tooth 213 is fixedly installed at the bottom of the screw 211, and a second conical tooth 214 is symmetrically fixedly installed on the outside of the drive rod 209. The first conical tooth 213 and the second conical tooth 214 are meshed together, thereby achieving the effect of quickly cleaning the external impurities of the filter bag body 203. This can effectively reduce the phenomenon of dust accumulation on the surface of the filter bag body 203 causing poor filtration, and can also effectively reduce the number of times the staff cleans and maintains the filter bag body 203, thereby improving the service life and efficiency of the filtration device.

[0029] Both sides of the cleaning plate 205 are symmetrically connected to support rods 2151, with the bottom of the support rods 2151 fixedly connected to the support frame 204, and the top of the support rods 2151 passing through the fixed plate 201 and slidably connected to it. The cleaning plate 205 slides outside the four support rods 2151, making its movement more stable. The cleaning plate 205 has slots 216 inside, and a heat dissipation box 217 is fixedly installed at one end of the housing 1 near the forward / reverse motor 210. A plug 218 is inserted into the lower interior of the discharge pipe 104, allowing the cleaning plate 205 to move through the slots 2151 and 216. The design of 6 effectively reduces the accumulation of dust and impurities on the top of the cleaning plate 205. The design of the heat dissipation box 217 provides physical protection for the external surface of the forward and reverse motors 210. The built-in filter structure inside the heat dissipation box 217 also helps to dissipate heat from the forward and reverse motors 210. The design of the plug 218 facilitates the sealing of the bottom of the discharge pipe 104. The plug 218 can be fixedly connected to the discharge pipe 104 using existing bolts and other structures, making it convenient for the staff to clean and discharge the impurities accumulated inside the housing 1.

[0030] The fixing component 3 includes a limiting box 301, which is symmetrically fixedly installed inside the end cover 103. Slots 302 are symmetrically opened on the outer top of the housing 1. A threaded tube 303 is fixedly installed inside the limiting box 301, and a threaded rod 304 is threadedly connected inside the threaded tube 303. A push plate 305 is rotatably connected to one end of the threaded rod 304. An insert plate 306 is welded to the side of the push plate 305 away from the threaded rod 304. The insert plate 306 is inserted into the slot 302. A retraction rod 307 is symmetrically fixedly installed between the inner side of the limiting box 301 and the push plate 305. A retraction spring 308 is sleeved on the outside of the retraction rod 307. This enables the quick installation and removal of the end cover 103, which facilitates the subsequent inspection and maintenance of the internal filter structure of the housing 1 by the staff. This greatly improves the daily maintenance efficiency of the device and enhances the flexibility and efficiency of the device during use.

[0031] Working principle: Before using this self-cleaning dust collector filter bag device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 7As shown, the operator first connects one end of the inlet pipe 101 to the external exhaust gas pipe, and then connects one end of the exhaust pipe 102 to the gas purification pipe. When the gas enters the housing 1 through the inlet pipe 101, multiple sets of filter bag bodies 203 filter the dust and impurities in the gas. The filtered gas is then discharged through the exhaust pipe 102. The power supply module provides power to the electrical equipment, and the controller controls the operation of the electrical equipment. The operator places the filter bag body 203 onto the outside of the cylinder frame 202 and positions the filter bag body 203 using strapping. Then, the operator evenly inserts multiple sets of cylinder frames 202. In the pre-reserved groove inside the fixing plate 201, the operator inserts the end cap 103 into the top of the housing 1. At this time, the bottom of the end cap 103 presses and limits the top of the cylinder frame 202. When it is necessary to clean the impurities attached to the outside of the filter bag body 203, the operator starts the forward and reverse motor 210 to drive the drive rod 209 to rotate. The rotation of the drive rod 209 drives the rotation of the two sets of second conical teeth 214. The rotation of the second conical teeth 214 drives the rotation of the first conical teeth 213. The rotation of the first conical teeth 213 drives the rotation of the screw 211. The rotation of the screw 211 drives the lifting rod 212 to slide longitudinally inside the strip box 207, so that the two sets of lifting rods 212 move together. The up-and-down movement of the cleaning plate 205 causes the cleaning plate 205 to move. This movement of the cleaning plate 205 drives multiple sets of annular brush plates 206 to clean the exterior of the filter bag body 203. The brush bristles evenly sweep away accumulated impurities from the exterior of the filter bag body 203, achieving a rapid initial cleaning of the external impurities. This effectively reduces dust accumulation on the surface of the filter bag body 203, preventing filtration problems and reducing the frequency of cleaning and maintenance by personnel, thus improving the service life and efficiency of the filtration device. The cleaning plate 205 slides outside the four support rods 2151, allowing it to move. The design of the slot 216 effectively reduces the accumulation of dust and impurities on the top of the cleaning plate 205. The design of the heat dissipation box 217 provides physical protection for the external surface of the forward and reverse motors 210. The built-in filter structure inside the heat dissipation box 217 also helps to dissipate heat from the forward and reverse motors 210. The design of the block 218 makes it easy for workers to seal the bottom of the discharge pipe 104. Workers can use existing technologies such as bolts to fix the block 218 to the discharge pipe 104, which facilitates the subsequent cleaning and discharge of impurities accumulated inside the housing 1.

[0032] When the operator inserts the end cap 103 into the top of the housing 1, the rubber plate at the bottom of the end cap 103 is pressed against the inside of the housing 1. At this time, the operator rotates multiple sets of threaded rods 304 inside the threaded tube 303. The rotation of the threaded rods 304 causes the push plate 305 to slide inside the limit box 301. At this time, the insertion plate 306 is inserted into the slot 302. The movement of the push plate 305 causes the two sets of retraction rods 307 and retraction springs 308 to extend and reset. The tension generated by the retraction springs 308 makes the connection between the insertion plate 306 and the slot 302 more stable, thereby achieving the effect of quick installation and removal of the end cap 103. This facilitates the subsequent inspection and maintenance of the internal filter structure of the housing 1, greatly improving the daily maintenance efficiency of the device and increasing the flexibility and efficiency of the device during use.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
