Description

Technical Field

[0001] This utility model relates to the technical field of pulse bag dust collector equipment, specifically an anti-clogging pulse bag dust collector. Background Technology

[0002] A pulse jet baghouse dust collector is a dry dust filtration device. When dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust particles passes through the filter media, the dust is trapped, thus purifying the gas. It uses filter bags as the filter medium and regularly cleans the dust on the filter bags through a pulse jet cleaning system to ensure the continuous and efficient operation of the equipment.

[0003] When a pulse-jet baghouse dust collector filters the atmosphere, the gas enters the machine body through the dust inlet pipe of the ash hopper, and then enters the filter chamber to filter impurities in the gas. However, heavier impurities in the gas do not enter the filter chamber from the ash hopper and fall onto the inner wall of the ash hopper. As the usage time increases, the dust that falls onto the inner wall will cause blockage of the ash hopper, thus affecting the use of the dust collector. Utility Model Content

[0004] The purpose of this invention is to address the problem that in pulse-jet baghouse dust collectors, when filtering air, gas enters the machine body through the dust inlet pipe of the ash hopper and then enters the filter chamber to filter impurities in the gas. However, heavier impurities in the gas do not enter the filter chamber from the ash hopper and fall onto the inner wall of the ash hopper. As the usage time increases, the dust falling onto the inner wall will cause blockage of the ash hopper, thus affecting the use of the dust collector. Therefore, this invention provides an anti-clogging pulse-jet baghouse dust collector.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging pulse bag filter, comprising a dust collector body, a dust hopper fixedly installed at the bottom of the dust collector body, and a dust inlet pipe fixedly installed at one end of the dust hopper; support rods evenly and symmetrically fixedly installed at the bottom of the dust collector body; an anti-clogging component for striking the outer wall of the dust hopper is provided in the middle of the two sets of support rods; the anti-clogging component includes a mounting cabinet fixedly installed in the middle of the two sets of support rods, a transmission block symmetrically fixed at one end of the mounting cabinet, and a striking hammer slidably connected to the inner side of the transmission block for striking the dust hopper; a return spring inside the transmission block and sleeved on the outer periphery of the striking hammer; and a rotating motor fixedly installed inside the mounting cabinet. Furthermore, a rotating main shaft is rotatably connected to the top of the rotating motor. A drive wheel is symmetrically fixedly installed on the outer periphery of the rotating main shaft. A rotating shaft is symmetrically rotatably connected inside the mounting cabinet, and a driven wheel is fixedly installed on the outer periphery of the rotating shaft. A connecting belt is connected between the drive wheel and the driven wheel. One end of the striking hammer passes through the transmission block and is connected to the inside of the mounting cabinet. A connecting rod is rotatably connected to one end of the connecting rod. An L-shaped connecting rod is fixedly installed at the bottom end of the connecting rod and is connected to the rotating shaft. A toggle ring is fixedly installed on the outer periphery of the rotating shaft and at the middle of the L-shaped connecting rod and the driven wheel. A toggle block is fixedly installed at one end of the toggle ring. A round rod that contacts the toggle block is fixedly installed at the top of the L-shaped connecting rod.

[0006] As a further improvement of this utility model, a rubber protective head is nested at one end of the striking hammer near the ash hopper.

[0007] As a further improvement of this utility model, an air bag assembly is provided on the top side of one end of the dust collector body to facilitate backflushing and cleaning of the internal filter bags.

[0008] As a further improvement of this utility model, a discharge pipe for discharging clean air is fixedly installed at one end of the dust collector body.

[0009] As a further improvement of this utility model, one end of the ash hopper has a maintenance gate that facilitates inspection and repair by staff.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The hammer of this utility model is pulled into the transmission block by the connecting rod and the L-shaped connecting rod. When the round rod rotates more than half a turn and is released from the restriction of the actuating block, the hammer can be ejected from the transmission block by the return spring to strike the outer wall of the ash hopper. This process is repeated to knock down the impurities and dust that fall on the inner wall of the ash hopper, reducing the situation where impurities fall on the inner wall and cause blockage.

[0012] 2. The rubber protective head at one end of the hammer can reduce the damage to the outer wall of the ash hopper during impact, thus increasing the service life of the ash hopper. Attached Figure Description

Support rods 6 are evenly and symmetrically fixedly installed at the bottom of the dust collector body 1. An anti-clogging component 3 for striking the outer wall of the dust hopper 2 is provided in the middle of the two sets of support rods 6. The anti-clogging component 3 includes a mounting cabinet 31 fixedly installed in the middle of the two sets of support rods 6, a transmission block 38 symmetrically fixed at one end of the mounting cabinet 31, and a striking hammer 39 slidably connected to the inner side of the transmission block 38 for striking the dust hopper 2. A return spring 310 is inside the transmission block 38 and sleeved on the outer periphery of the striking hammer 39. A rotating motor 32 is fixedly installed inside the mounting cabinet 31, and a rotating main shaft 34 is rotatably connected to the top of the rotating motor 32. A drive wheel 35 is symmetrically fixedly installed on the outer periphery of shaft 34. A rotating shaft 33 is symmetrically rotatably connected inside the mounting cabinet 31, and a driven wheel 36 is fixedly installed on the outer periphery of the rotating shaft 33. A connecting belt 37 is connected between the drive wheel 35 and the driven wheel 36. One end of the hammer 39 passes through the transmission block 38 and is connected to the inside of the mounting cabinet 31 with a connecting end 311. A connecting rod 312 is rotatably connected to one end of the connecting end 311. An L-shaped connecting rod 313 is fixedly installed at the bottom of the connecting rod 312 and is connected to the rotating shaft 33. A toggle ring 315 is fixedly installed on the outer periphery of the rotating shaft 33 and located in the middle of the L-shaped connecting rod 313 and the driven wheel 36. A toggle block 316 is fixedly provided at one end of the toggle ring 315. A round rod 314 that contacts the toggle block 316 is fixedly provided at the top of the L-shaped connecting rod 313.

[0022] Reference Figures 1 to 5 A rubber protective head 317 is nested at one end of the striking hammer 39 near the side of the ash hopper 2.

[0023] Reference Figures 1 to 5 The dust collector body 1 has an air bag assembly 5 on one top side to facilitate backflushing and cleaning of the internal filter bags. The dust collector body 1 has a discharge pipe 8 fixedly installed at one end for the discharge of clean air. The dust hopper 2 has a maintenance door 7 at one end for easy inspection and maintenance by staff.

[0024] The working principle of this utility model is as follows: When the operator uses the dust collector body 1 to filter the atmosphere, the gas enters the ash hopper 2 through the dust inlet pipe 4, and then enters the filter chamber inside the dust collector body 1 for filtration. When some impurities in the gas cannot smoothly enter the filter chamber and fall into the inner wall of the ash hopper 2, the operator starts the rotating motor 32. The rotating motor 32 drives the rotating main shaft 34 at the top to rotate, which in turn drives the driving wheel 35 to rotate. Through the connecting belt 37, the driven wheel 36 can be driven to rotate, which in turn drives the rotating shaft 33 to rotate. As the rotating shaft 33 rotates, it drives the actuating block 316 at one end of the actuating ring 315 to rotate. As the actuating block 316 rotates, it can... The round rod 314 at the top of the L-shaped connecting rod 313 moves, which in turn drives the L-shaped connecting rod 313 to rotate. As the L-shaped connecting rod 313 rotates, the striking hammer 39 is pulled into the transmission block 38 through the connecting rod 312 and the L-shaped connecting rod 313. When the round rod 314 rotates more than half a turn and is released from the restriction of the actuating block 316, the return spring 310 can instantly eject the striking hammer 39 from the transmission block 38 to strike the outer wall of the ash hopper 2. This process is repeated to knock down the impurities and dust that fall on the inner wall of the ash hopper 2, reducing the possibility of impurities falling on the inner wall and causing blockage. At the same time, the rubber protective head 317 at one end of the striking hammer 39 can reduce the damage to the outer wall of the ash hopper 2 during the strike, increasing the service life of the ash hopper 2.
