Description

A pulse dust collector with easy-to-clean filter Technical Field

[0001] This utility model relates to a pulse dust collector, specifically a pulse dust collector that facilitates filter cleaning, and belongs to the technical field of pulse dust collectors. Background Technology

[0002] A pulse jet dust collector is a purification device that removes dust by blowing compressed air. Dust-laden gas first undergoes pre-dust removal through inclined plates and baffles at the inlet, separating coarse dust particles. Then, fine dust particles are captured by filter bags, achieving fine filtration with a dust removal efficiency of over 99% and low emission concentrations, meeting stringent environmental standards. The equipment uses pulse jet cleaning; compressed air is instantly injected into the filter bags, causing them to expand and shake rapidly, quickly removing surface dust.

[0003] However, if the dust entering the dust collector is highly viscous (such as damp dust or oily dust) or has fine particles, the pulse jet cleaning may not be able to completely remove the dust from the pores of the filter bag. Long-term accumulation will clog the filter material, affecting the air permeability, and requiring manual disassembly and cleaning. However, if the gap between the filter bag and the dust collector housing is too small, it is difficult to operate during disassembly, which is not conducive to removing the filter bag for cleaning. Summary of the Invention

[0004] The purpose of this utility model is to provide a pulse dust collector that facilitates filter cleaning in order to solve the above problems. When the hydraulic rod drives the rotating rod to rotate, the connecting shaft drives the abutment rod to rotate, which can separate the abutment rod from the filter screen, thereby allowing the filter screen to be removed from the dust collector. At the same time, the filter screen can also be cleaned or replaced.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a pulse dust collector for easy filter cleaning, comprising a housing, a fixed plate fixedly connected to the housing, two sets of abutment mechanisms symmetrically fixed at the bottom end of the fixed plate, each abutment mechanism comprising a mounting block and a hydraulic rod, two sets of mounting blocks and a support plate symmetrically fixedly connected at the bottom end of the fixed plate, a hydraulic rod rotatably mounted on the mounting block, a rotating rod rotatably mounted on the telescopic end of the hydraulic rod, a connecting shaft fixedly connected to the rotating rod, the connecting shaft rotatably connected to the support plate, a stop rod fixedly mounted on the connecting shaft, the stop rod contacting the filter mechanism, and a back-blowing mechanism engaged on the fixed plate, the back-blowing mechanism communicating internally with the filter mechanism.

[0006] Preferably, the support plate is arranged in an L-shape, and the rotating rod and the abutment rod are rotatably connected to the support plate.

[0007] Preferably, the filtration mechanism includes a sliding plate and a sleeve. A plurality of sliding plates are slidably installed between the two support plates. A retaining ring and a sleeve are fixedly connected to the sliding plate, and a filter bag is threaded onto the sleeve.

[0008] Preferably, the retaining ring and the fixing plate are engaged, and the fixing plate is connected to the interior of the filter bag through the retaining ring.

[0009] Preferably, the width of the slide plate is equal to the distance between the top ends of the two support plates, and the diameter of the sleeve is equal to the distance between the bottom ends of the two support plates.

[0010] Preferably, the abutment bar abuts against the bottom end of the slide plate, and the slide plate abuts against the bottom end of the fixing plate.

[0011] Preferably, a dust hopper is fitted onto the part of the housing near the filter bag, and an air inlet pipe is connected to the housing.

[0012] Preferably, the backflushing mechanism includes a blow pipe and a sealing plate. Two sets of sealing plates are engaged and installed on the fixed plate, and a blow pipe is engaged and installed on the sealing plate. A pulse controller is fixedly installed on the housing, and the blow pipe is internally connected to the pulse controller.

[0013] Preferably, the blowpipe is located at the top of the fixed plate, and the end of the blowpipe near the sealing plate is in communication with the interior of the filter bag.

[0014] The beneficial effects of this utility model are as follows: When it is necessary to clean or replace the filter screen inside the dust collector, the operator can activate the control switch of the hydraulic rod. The hydraulic rod is rotatably mounted on the side wall of the mounting block at the bottom of the fixed plate. When the telescopic end of the hydraulic rod drives the rotating rod connected to it to rotate, the connecting shaft fixed at the drive end of the rotating rod can rotate along the support plate. A stop rod is fixed on the connecting shaft. One end of the stop rod with an arc surface structure can separate from the dust collector filter screen when it rotates with the connecting shaft, thereby allowing the dust collector filter screen to slide out from the fixed plate. Then, the dust collector filter screen can be pulled out from between the two support plates. Thus, the filter screen can be removed from the fixed plate and cleaned or replaced at the same time.

A stop rod 506 is fixedly installed on the connecting shaft 505. The rotating rod 504 and the stop rod 506 are rotatably connected to the support plates 501. The extension end of the hydraulic rod 503 drives the rotating rod 504 to rotate, which in turn drives the stop rod 506 on the connecting shaft 505 to rotate. After the stop rod 506 rotates, it separates from the filter bag 601, thereby allowing the filter bag 601 to slide out from the fixed plate 4. The filter bag 601 can then be pulled out from between the two support plates 501. The stop rod 506 contacts the filter mechanism 6. A back-blowing mechanism 3 is engaged and installed on the fixed plate 4. The back-blowing mechanism 3 is internally connected to the filter mechanism 6.

[0027] As a technical optimization of this utility model, the filtration mechanism 6 includes a sliding plate 603 and a sleeve 604. A plurality of sliding plates 603 are slidably installed between the two support plates 501. The abutment rod 506 abuts against the bottom end of the sliding plate 603, and the sliding plate 603 abuts against the bottom end of the fixing plate 4. A retaining ring 602 and a sleeve 604 are fixedly connected to the sliding plate 603. A filter bag 601 is threaded onto the sleeve 604. The retaining ring 602 is engaged with the fixing plate 4. The fixing plate 4 is connected by a retaining ring... The ring 602 is internally connected to the filter bag 601. When the slide plate 603 is removed from the support plate 501, the filter bag 601 is rotated out from the sleeve 604, allowing the filter bag 601 to be replaced. The width of the slide plate 603 is equal to the distance between the top ends of the two support plates 501, and the diameter of the sleeve 604 is equal to the distance between the bottom ends of the two support plates 501. The filtered gas enters the filter bag 601 and, through the fixing plate 4 and the sealing plate 303, can be transported to the part of the housing 1 near the fixing plate 4.

[0028] As a technical optimization of this utility model, a dust hopper 2 is fitted and installed on the part of the housing 1 near the filter bag 601. An air inlet pipe 7 is connected to the housing 1. Dust-laden gas enters the part of the housing 1 near the filter bag 601 through the air inlet pipe 7. The filter bag 601 captures fine dust particles and achieves fine filtration.

[0029] As a technical optimization of this utility model, the back-blowing mechanism 3 includes a blow pipe 302 and a sealing plate 303. Two sets of sealing plates 303 are snapped onto the fixed plate 4, and the blow pipe 302 is snapped onto the sealing plate 303. A pulse controller 301 is fixedly installed on the housing 1. The blow pipe 302 is internally connected to the pulse controller 301. When back-blowing the filter bag 601, the pulse controller 301 can deliver compressed air into the filter bag 601 through the blow pipe 302. The blow pipe 302 is located at the top of the fixed plate 4, and the end of the blow pipe 302 near the sealing plate 303 is connected to the inside of the filter bag 601. Compressed air is instantly sprayed into the filter bag 601, causing the filter bag 601 to expand and shake rapidly, quickly peeling off surface dust, resulting in thorough and efficient dust removal.

[0030] In use, dust-laden gas enters the housing 1 near the filter bag 601 through the inlet pipe 7 installed inside the housing 1. The filter bag 601 captures fine dust particles, achieving fine filtration. The filtered gas enters the filter bag 601 and is transported to the housing 1 near the fixed plate 4 via the fixing plate 4 and the sealing plate 303. When backflushing the filter bag 601, compressed air is delivered to the filter bag 601 through the jet pipe 302 via the pulse controller 301. The compressed air is instantly injected into the filter bag 601, causing it to expand and shake rapidly, quickly removing surface dust for thorough and efficient cleaning. If the dust is highly viscous (such as damp dust or oily dust) or has fine particles, the pulse jet may not be able to completely remove the dust from the pores of the filter bag 601. Long-term accumulation will clog the filter material and affect the air permeability, requiring the filter bag 601 to be disassembled. When disassembling and cleaning the filter bag 601, the operator... The operator can activate the control switch of the hydraulic rod 503. The hydraulic rod 503 is rotatably mounted on the side wall of the mounting block 502 at the bottom of the fixed plate 4. When the telescopic end of the hydraulic rod 503 drives the rotating rod 504 connected to it to rotate, the rotating rod 504 drives the connecting shaft 505 fixed at its end to rotate along the support plate 501. A stop rod 506 is fixed on the connecting shaft 505. One end of the stop rod 506, which has an arc-shaped structure, can separate from the filter bag 601 when it rotates with the connecting shaft 505, thereby allowing the filter bag 601 to slide out from the fixed plate 4. Then, the filter bag 601 can be pulled out from between the two support plates 501. Thus, the filter bag 601 can be removed from the fixed plate 4 and can also be disassembled, cleaned, or replaced. When the sliding plate 603 is taken out from the support plate 501, the filter bag 601 is rotated out from the sleeve 604 installed at the end of the sliding plate 603, thereby allowing the filter bag 601 to be replaced.
