Description

Technical Field

[0001] This invention relates to the field of dust collector technology, and in particular to a high negative pressure dust collector and a dust removal method that facilitates dust removal. Background Technology

[0002] A high negative pressure dust collector is an environmental protection device that uses high negative pressure suction to clean and remove dust. It is often used in industrial production to efficiently remove dust particles. The dust collector is usually also equipped with pulse dust removal, which allows compressed air to enter the dust collector and quickly and easily clean the dust attached to the filter cartridge inside the dust collector.

[0003] During the operation of a dust collector, although the pulse jet dust collector can effectively remove dust from the surface of the filter cartridges inside the equipment, some dust may still adhere to the inner wall of the ash discharge pipe when it is discharged through the ash discharge pipe at the bottom of the equipment. After a long period of accumulation, this dust is not only difficult to clean, but may also accumulate inside the ash discharge pipe, reducing the effectiveness and efficiency of dust discharge. Summary of the Invention

[0004] The purpose of this invention is to address the problem that dust may still adhere to the inner wall of the ash discharge pipe when it is discharged through the bottom of the equipment. Over time, this dust is not only difficult to clean, but may also accumulate inside the ash discharge pipe, reducing the effectiveness and efficiency of dust discharge. Therefore, this invention proposes a high negative pressure dust collector and a dust removal method that facilitates dust removal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high negative pressure dust collector that is easy to clean, comprising a frame, a cylinder fixedly connected to the top of the frame; an air inlet pipe and an air outlet pipe respectively provided on the outer surface of the cylinder; a pulse dust collector provided at the top of the cylinder; a filter cartridge for filtering air provided inside the cylinder; and an ash outlet pipe fixedly connected to the bottom of the cylinder, and the ash outlet pipe communicating with the interior of the cylinder.

[0006] The effect achieved by the above components is as follows: When the high negative pressure dust collector is working, one end of the extraction pipe is connected to the inlet pipe through a flange, and one end of the fan pipe is connected to the outlet pipe through a flange. Then the fan is operated, and the negative pressure air force is generated by the fan to control the extraction pipe to absorb impurities in the environment. Alternatively, the extraction pipe can be connected to the slag discharge pipe of other equipment. The air carries the impurities through the inlet pipe into the inside of the cylinder. After passing through the filter cartridge inside the cylinder, the particulate impurities in the air can be intercepted. Then the air will be output through the outlet pipe and the fan. The intercepted debris will be adsorbed on the outer surface of the filter cartridge. By controlling the operation of the pulse dust collector, compressed air can be filled into the inside of the filter cartridge, pushing the particulate impurities attached to the outer surface of the filter cartridge downward into the ash discharge pipe, and then output through the bottom of the ash discharge pipe.

[0007] Preferably, a cleaning device is provided on one side of the outer surface of the ash discharge pipe. The cleaning device includes a frame rod, one end of which is fixedly connected to one side of the inner wall of the ash discharge pipe, and the other end of which is fixedly connected to one side of the frame. A first shaft and a second shaft are rotatably connected to both ends of the inner wall of the frame rod, respectively. The center of the second shaft is on the same horizontal line as the center of the ash discharge pipe, and the lower end of the second shaft extends into the interior of the ash discharge pipe. A servo motor is provided on one side of the bottom end of the frame rod, and the output end of the servo motor is connected to... A coupling is fixedly connected to the bottom end of the first shaft; pulleys are fixedly connected to the top ends of both the first and second shafts, and a belt is fitted onto the outer surfaces of both pulleys to achieve synchronous transmission between the first and second shafts; several scraper blades are fixedly connected to the bottom end of the second shaft, and the scraper blades are evenly distributed along the circumference of the second shaft, with the edges of the scraper blades adhering to the inner wall of the outlet end of the ash discharge pipe; a brush rod is fixedly connected to one side of the bottom end of the second shaft, and the brush rod faces the outlet... A plurality of stiff bristles are provided on one side of the inner wall of the ash discharge pipe, and the stiff bristles are in contact with the inner wall of the ash discharge pipe. A cleaning device is provided on one side of the outer surface of the ash discharge pipe. The cleaning device includes a frame rod, one end of which is fixedly connected to one side of the inner wall of the ash discharge pipe, and the other end of which is fixedly connected to one side of the frame. A first shaft and a second shaft are rotatably connected to both ends of the inner wall of the frame rod, respectively. The center of the second shaft is on the same horizontal line as the center of the ash discharge pipe, and the lower end of the second shaft extends into the inner wall of the ash discharge pipe. The frame rod has a servo motor installed on one side of its bottom end. The output end of the servo motor is fixedly connected to the bottom end of the first shaft rod via a coupling. The top ends of the first shaft rod and the second shaft rod are both fixedly connected to pulleys. The outer surfaces of the two pulleys are covered with a belt to achieve synchronous transmission between the first shaft rod and the second shaft rod. The bottom end of the second shaft rod is fixedly connected to several scrapers. The scrapers are evenly distributed along the circumference of the second shaft rod, and the edges of the scrapers are in contact with the inner wall of the outlet end of the ash discharge pipe.

[0008] The effect achieved by the above components is as follows: by setting the second shaft, during the use of the high negative pressure dust collector, the operation of the servo motor can be controlled periodically. The servo motor drives the first shaft to rotate. When the first shaft rotates, the pulley at the top drives the belt to move, thereby driving the pulley at the top of the second shaft to rotate synchronously with the second shaft. When the second shaft rotates, the scraper at the bottom of the ash discharge pipe will rotate at the bottom outlet of the ash discharge pipe. The scraper will scrape the bottom outlet of the ash discharge pipe. At the same time, the side of the brush rod with hard bristles will be attached to the inner wall of the ash discharge pipe and rotate to clean the inner wall of the ash discharge pipe, sweeping off the dust that is attached to and accumulated inside the ash discharge pipe.

[0009] Preferably, a brush rod is fixedly connected to one side of the bottom end of the second shaft, and the brush rod is provided with a plurality of hard bristles on the side facing the inner wall of the ash outlet pipe, and the hard bristles are in contact with the inner wall of the ash outlet pipe.

[0010] The effect achieved by the above components is that by setting a conical protective cover, dust can be prevented from entering the pulley at the top of the second shaft as much as possible.

[0011] Preferably, two protruding rods are fixedly connected to the outer surface of the first shaft, and the two protruding rods are symmetrically distributed along the circumference of the first shaft; a rotating shaft is rotatably connected to one side of the bottom end of the frame rod, and a coil spring is provided at one end of the rotating shaft. One end of the coil spring is fixedly connected to the frame rod, and the other end of the coil spring is fixedly connected to the rotating shaft; two striking rods are fixedly connected to the outer surface of the rotating shaft, and the two striking rods are distributed along the circumference of the rotating shaft, with the ends of the two striking rods away from the rotating shaft respectively in contact with the bottom end of the frame rod and the outer surface of the ash discharge pipe; a groove block is fixedly connected to the other side of the rotating shaft, and an inclined groove is opened at the bottom end of the groove block. When the protruding rod rotates with the first shaft rod, it can be embedded in the inclined groove and push the groove block to drive the rotating shaft to rotate, so that the coil spring deforms.

[0012] The effect achieved by the above components is as follows: During the rotation of the first rotating shaft, one end of the protruding rod on the outer surface will enter the inclined groove at the bottom of the groove block. The contact between the protruding rod and the bottom of the groove block will push the groove block to control the rotation of the groove block and the rotating shaft in the direction of the groove block, and cause the coil spring to deform. At the same time, it will drive the striking rod away from the bottom of the frame rod and the outer surface of the ash discharge pipe. When the protruding rod is away from the outer surface of the groove block, the coil spring returns to its original state and drives the rotating shaft and the striking rod to rotate in the original direction, so that the striking rod strikes the bottom of the frame rod and the outer surface of the ash discharge pipe, causing the frame rod and the ash discharge pipe to vibrate, shaking off the dust attached to the inner wall of the frame rod and the ash discharge pipe, thus improving the cleaning effect on the ash discharge pipe.

[0013] Preferably, the two ends of the inclined groove on the outer surface of the groove block are arc-shaped, and the edge of the protruding rod away from the second shaft is arc-shaped, so as to achieve smooth engagement and disengagement of the protruding rod and the inclined groove.

[0014] The effect achieved by the above components is that by setting the two ends of the inclined groove on the outer surface of the slot block and the edge of the protruding rod away from the second shaft rod to be arc-shaped, it is easier and less likely for the protruding rod to enter the outer surface of the slot block.

[0015] Preferably, a limiting rod is fixedly connected to one end of the rotating shaft. The limiting rod is located below the groove block, and when the rotating shaft rotates, the limiting rod can abut against the bottom end of the frame rod to limit the maximum rotation angle of the rotating shaft.

[0016] The effect achieved by the above components is that when the shaft rotates upward, the rotation range of the shaft can be limited by the limiting rod, so that the shaft and the striking rod rotate at the same angle each time they are driven to rotate by the convex rod and the groove block.

[0017] Preferably, a sleeve is fixedly connected to the end of the striking rod away from the rotating shaft. The sleeve is made of rubber and is respectively attached to the bottom end of the frame rod and the outer surface of the ash discharge pipe.

[0018] The effect achieved by the above components is that, by setting a rubber sleeve, the striking rod will not produce a large abnormal noise when it comes into contact with the outer surface of the frame rod and the ash discharge pipe.

[0019] Preferably, a dust removal method for a high negative pressure dust collector that facilitates dust removal, using the aforementioned high negative pressure dust collector, includes the following steps:

[0020] S1. Connect the extraction pipeline to the inlet pipe of the dust collector cylinder through a flange, and connect the fan pipeline to the outlet pipe of the cylinder through a flange; start the fan to generate negative pressure, so that the dust-laden air enters the cylinder through the inlet pipe, and the filter cartridge inside the cylinder intercepts particulate impurities. The clean air is discharged through the outlet pipe and the fan. Control the operation of the pulse dust collector at the top of the cylinder to fill the filter cartridge with compressed air, and push the particulate impurities attached to the outer surface of the filter cartridge downward into the ash discharge pipe.

[0021] S2. Periodically start the servo motor of the ash discharge pipe side cleaning device. The servo motor drives the first shaft to rotate through the coupling. The pulley at the top of the first shaft drives the second shaft to rotate synchronously through the belt. When the second shaft rotates, several scrapers at its bottom rotate and scrape at the outlet of the ash discharge pipe. At the same time, the brush rod on one side of the second shaft rotates with hard bristles against the inner wall of the ash discharge pipe to clean the dust attached to and accumulated on the inner wall of the ash discharge pipe.

[0022] S3. During the rotation of the first shaft, the two protruding rods on its outer surface circulate into the inclined groove at the bottom of the groove block, pushing the groove block to drive the rotating shaft to rotate and deform the coil spring, thereby driving the two striking rods away from the bottom of the frame rod and the outer surface of the ash discharge pipe. When the protruding rods are separated from the groove block, the coil spring returns to its original state and drives the rotating shaft to rotate in the opposite direction. The striking rods strike the bottom of the frame rod and the outer surface of the ash discharge pipe through the rubber sleeve, using vibration to shake off the attached residual dust.

[0023] S4. The dust, after being scraped, swept, and vibrated, is naturally discharged through the bottom of the ash outlet pipe, completing a single dust removal process.

[0024] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0025] In this invention, a cleaning device is provided. By installing a scraper and a brush rod driven to rotate by a second shaft on the inner wall of the ash discharge pipe, the scraper and brush rod clean the outlet and inner wall of the ash discharge pipe respectively, which facilitates the removal of dust adhering to and accumulating inside the ash discharge pipe, and avoids the problem of dust accumulating inside the ash discharge pipe and causing blockage, thus affecting the normal discharge of dust from the ash discharge pipe.

[0032] like Figure 1-3As shown, this invention provides a high negative pressure dust collector and cleaning method for easy dust removal. It includes a frame 1, a cylinder 3 fixedly connected to the top of the frame 1, an inlet pipe 4 and an outlet pipe 5 respectively disposed on the outer surface of the cylinder 3, a pulse dust collector 6 disposed at the top of the cylinder 3, a filter cartridge for filtering air disposed inside the cylinder 3, and an ash discharge pipe 7 fixedly connected to the bottom of the cylinder 3. A cleaning device 2 for easy cleaning of the inside of the ash discharge pipe 7 is disposed on one side of the outer surface of the ash discharge pipe 7. When the high negative pressure dust collector is working, the extraction pipe is connected to one end of the inlet pipe 4 via a flange, and the fan pipe is connected to one end of the outlet pipe 5 via a flange. The system connects to the air intake pipe 4, then operates the fan. The fan generates negative pressure and controls the extraction pipe to absorb impurities in the environment, or connects the extraction pipe to the slag discharge pipe of other equipment. The air carries impurities through the air inlet pipe 4 into the cylinder 3. After passing through the filter cartridge inside the cylinder 3, the particulate impurities in the air can be intercepted. Then the air will be output through the air outlet pipe 5 and the fan. The intercepted impurities will be adsorbed on the outer surface of the filter cartridge. By controlling the operation of the pulse dust collector 6, compressed air can be filled into the filter cartridge, pushing the particulate impurities attached to the outer surface of the filter cartridge downward into the ash discharge pipe 7, and then output through the bottom end of the ash discharge pipe 7.

[0033] Reference Figure 1-5As shown in this embodiment: the cleaning device 2 includes a frame 21, with both ends of the frame 21 fixedly connected to one side of the inner wall of the ash discharge pipe 7 and one side of the frame 1, respectively. A first shaft 23 and a second shaft 24 are rotatably connected to both ends of the inner wall of the frame 21, respectively. The center of the second shaft 24 is at the same horizontal line as the center of the ash discharge pipe 7. A servo motor 22 is installed on one side of the bottom of the frame 21, and the output end of the servo motor 22 is fixedly connected to the bottom of the first shaft 23 via a coupling. Pulleys are fixedly connected to the top ends of the first shaft 23 and the second shaft 24, respectively, with belts fitted on their outer surfaces. Several scraper blades 25 are fixedly connected to the bottom of the second shaft 24, and a brush rod 26 is fixedly connected to one side of the bottom of the second shaft 24. Several hard bristles are provided on the side of the brush rod 26 facing the inner wall of the ash discharge pipe 7. By setting the second shaft 24, the operation of the servo motor 22 can be periodically controlled during the use of the high negative pressure dust collector. Motor 22 drives the first shaft 23 to rotate. When the first shaft 23 rotates, it drives the belt to move through the pulley at the top, thereby driving the pulley at the top of the second shaft 24 and the second shaft 24 to rotate synchronously. When the second shaft 24 rotates, the scraper 25 at the bottom of the ash discharge pipe 7 will rotate at the bottom outlet of the ash discharge pipe 7. The scraper 25 scrapes and sweeps the bottom outlet of the ash discharge pipe 7. At the same time, the side of the brush rod 26 with hard bristles will be attached to the inner wall of the ash discharge pipe 7 and rotate to clean the inner wall of the ash discharge pipe 7, sweeping off the dust attached and accumulated inside the ash discharge pipe 7. By setting up the cleaning device 2, by installing the scraper 25 and the brush rod 26 driven to rotate by the second shaft 24 on the inner wall of the ash discharge pipe 7, the scraper 25 and the brush rod 26 respectively clean the outlet and inner wall of the ash discharge pipe 7, which facilitates the sweeping out of the dust attached and accumulated inside the ash discharge pipe 7, and avoids the problem of dust accumulation inside the ash discharge pipe 7 causing blockage and affecting the normal dust discharge of the ash discharge pipe 7.

[0034] Reference Figure 2-5 As shown in this embodiment: a protective cover 27 is fixedly connected to the top of the second shaft 24. The outer surface of the protective cover 27 is conical. By setting the conical protective cover 27, dust can be prevented from entering the pulley at the top of the second shaft 24 as much as possible.

[0035] Reference Figure 2-5As shown in this embodiment: two protruding rods 28 are fixedly connected to the outer surface of the first shaft 23; a rotating shaft 29 is rotatably connected to one side of the bottom end of the support rod 21; a coil spring 210 is provided at one end of the rotating shaft 29; two striking rods 211 are fixedly connected to the outer surface of the rotating shaft 29; the ends of the two striking rods 211 away from the rotating shaft 29 respectively abut against the bottom end of the support rod 21 and the outer surface of the ash discharge pipe 7; a groove block 212 is fixedly connected to the other side of the rotating shaft 29; a sloping groove is opened at the bottom end of the groove block 212; during the rotation of the first rotating shaft 29, one end of the protruding rod 28 on the outer surface will enter the sloping groove at the bottom end of the groove block 212; the protruding rod 28 and... When the bottom of the slot block 212 contacts, it will push the slot block 212 to control the slot block 212 and the rotating shaft 29 to rotate in the direction of the slot block 212, and cause the coil spring 210 to deform. At the same time, it will drive the striking rod 211 away from the bottom of the frame rod 21 and the outer surface of the ash discharge pipe 7. When the protruding rod 28 is away from the outer surface of the slot block 212, the coil spring 210 returns to its original shape and drives the rotating shaft 29 and the striking rod 211 to rotate in the original direction, so that the striking rod 211 strikes the bottom of the frame rod 21 and the outer surface of the ash discharge pipe 7, causing the frame rod 21 and the ash discharge pipe 7 to vibrate, shaking off the dust attached to the inner wall of the frame rod 21 and the ash discharge pipe 7, thus improving the cleaning effect on the ash discharge pipe 7.

[0036] Reference Figure 2-5 As shown in this embodiment: the two ends of the inclined groove on the outer surface of the groove block 212 are arc-shaped, and the edge of the protruding rod 28 away from the second shaft 24 is arc-shaped. By setting the two ends of the inclined groove on the outer surface of the groove block 212 and the edge of the protruding rod 28 away from the second shaft 24 to be arc-shaped, it is easier and less likely for the protruding rod 28 to enter the outer surface of the groove block 212. One end of the rotating shaft 29 is fixedly connected to a limiting rod 213, which is located below the groove block 212. When rotating upwards, the rotation range of the rotating shaft 29 can be limited by the limiting rod 213, so that the rotating shaft 29 and the striking rod 211 rotate at the same angle each time they are driven to rotate by the protruding rod 28 and the groove block 212. The end of the striking rod 211 away from the rotating shaft 29 is fixedly connected to a sleeve 214. The sleeve 214 is made of rubber. By setting the rubber sleeve 214, the striking rod 211 will not make a large abnormal noise when it comes into contact with the outer surface of the frame rod 21 and the ash discharge pipe 7.

[0037] Working principle: When the high negative pressure dust collector is working, one end of the extraction pipeline is connected to the inlet pipe 4 via a flange, and the end of the fan pipeline is connected to the outlet pipe 5 via a flange. Then, the fan is operated, generating negative pressure and controlling the extraction pipeline to absorb impurities in the environment. Alternatively, the extraction pipeline can be connected to the slag discharge pipeline of other equipment. The air carries impurities through the inlet pipe 4 into the cylinder 3, where the filter cartridges inside the cylinder 3 intercept particulate impurities in the air. The air is then output through the outlet pipe 5 via the fan and is then... The intercepted debris adheres to the outer surface of the filter cartridge. By controlling the operation of the pulse dust collector 6, compressed air can be pumped into the filter cartridge, pushing the particulate matter and impurities attached to the outer surface of the filter cartridge downwards into the ash discharge pipe 7, where it is discharged through the bottom end. Simultaneously, the servo motor 22 can be periodically controlled to rotate the first shaft 23. When the first shaft 23 rotates, the pulley at its top drives the belt, which in turn drives the pulley at the top of the second shaft 24 to rotate synchronously with the second shaft 24. When in motion, the scraper 25 at the bottom of the ash discharge pipe 7 rotates at the bottom outlet, scraping the outlet. Simultaneously, the side of the brush rod 26 with stiff bristles rotates against the inner wall of the ash discharge pipe 7, cleaning the inner wall and removing dust adhering to and accumulating inside. During the rotation of the first rotating shaft 29, one end of the protruding rod 28 on its outer surface enters the inclined groove at the bottom of the trough block 212. The contact between the protruding rod 28 and the bottom of the trough block 212 pushes the trough block 212, controlling the trough block 212 and the rotating shaft. 29 rotates towards the direction of the groove block 212 and causes the coil spring 210 to deform. At the same time, it drives the striking rod 211 away from the bottom end of the frame rod 21 and the outer surface of the ash discharge pipe 7. When the protruding rod 28 moves away from the outer surface of the groove block 212, the coil spring 210 returns to its original state and drives the rotating shaft 29 and the striking rod 211 to rotate in the original direction. This causes the striking rod 211 to strike the bottom end of the frame rod 21 and the outer surface of the ash discharge pipe 7, causing the frame rod 21 and the ash discharge pipe 7 to vibrate. This shakes off the dust adhering to the inner wall of the frame rod 21 and the ash discharge pipe 7, improving the cleaning effect on the ash discharge pipe 7.

During the rotation of the first shaft (23), the two protruding rods (28) on its outer surface circulate into the inclined groove at the bottom of the groove block (212), pushing the groove block (212) to drive the rotating shaft (29) to rotate and deform the coil spring (210), thereby driving the two striking rods (211) away from the bottom of the frame rod (21) and the outer surface of the ash discharge pipe (7). When the protruding rod (28) is separated from the groove block (212), the coil spring (210) returns to its original state and drives the rotating shaft (29) to rotate in the opposite direction. The striking rods (211) strike the bottom of the frame rod (21) and the outer surface of the ash discharge pipe (7) through the rubber sleeve (214), using vibration to shake off the attached residual dust. S4. The dust, after being scraped, swept and vibrated, is naturally discharged through the bottom of the ash discharge pipe (7) to complete a single dust removal process.
