Description

Technical Field

[0001] The utility model relates to the technical field of dust collectors, and more specifically, to a dust collector used in the production of epoxy resin. Background Art

[0002] In the existing technology, the existing pulse dust collector mainly injects high-pressure air into the bag, and uses the instantaneous expansion and vibration of the air to impact the bag, so that the dust particles attached to the surface of the bag fall off and achieve cleaning. However, this cleaning method has certain limitations. Although the injection of high-pressure air can make the bag expand instantly, the removal effect is not ideal for dust particles deep inside the bag, especially those dusts that are tightly adhered or embedded in the cloth fibers. In addition, the repeated expansion and vibration process may also cause certain damage to the bag material and shorten its service life.

[0003] Secondly, the sealing problem of existing pulse dust collectors is also a defect that cannot be ignored. Since the one-way sealing requirement is not fully considered during the design and manufacturing process of the equipment, external dust may enter the equipment through the exhaust pipe or other gaps without exhausting the gas. This will not only affect the dust removal effect, but may also cause blockage of the filtration system, increase the workload of maintenance and cleaning, and thus affect the operating efficiency and stability of the entire equipment.

[0004] Furthermore, regarding the replacement of filters, the traditional pulse dust collector is not designed to provide an easy and quick replacement method. As the use time increases, the filters will be worn or clogged due to long-term dust filtering, and need to be replaced regularly to maintain good filtering performance. However, the existing replacement process is cumbersome and complicated, which not only consumes a lot of time and labor, but also increases the downtime of the production process, which has a negative impact on production efficiency.

[0033] A leak plate 12 is provided inside the box body 1 , and an electric push rod 13 is fixedly installed on the leak plate 12 . Reinforcement rods 14 are fixedly installed at both ends of the electric push rod 13 , and the reinforcement rods 14 are fixedly installed on the leak plate 12 .

[0034] A connecting pipe 15 is provided on the top of the box body 1 , an electromagnetic pulse valve 16 is provided on the connecting pipe 15 , and an air storage bag 17 is provided at one end of the connecting pipe 15 .

[0035] An air inlet pipe 18 is provided on one side of the box body 1 , and an ash hopper 19 is provided at the bottom of the box body 1 .

[0036] A push block 20 is connected to the bottom of the sliding rod 11 . The push block 20 fits with one end of the adjusting tube 9 . A push spring 21 is connected between the push block 20 and the threaded sleeve 10 .

[0037] In this embodiment, when the device is used, gas is manually injected into the box body 1 along the air inlet pipe 18, the gas will move upward along the venturi tube 2, and the cloth bag 3 sleeved on the outside thereof will filter out the dust. When the dust needs to be processed, the electric push rod 13 is manually started to drive the connecting rod 6 at the output end to move. During the movement, the slip ring 5 is driven to slide along the outer rod 4, and cooperates with the scraper 7 set on the inner side of the slide rod to scrape off the dust filtered out of the outside of the cloth bag 3, so that it falls on the leak plate 12 inside the box body 1, and finally discharged along the ash hopper 19. The gas storage bag 17 is manually used and the electromagnetic pulse valve 16 is opened, so that the gas is discharged along the connecting rod 6.

After the gas discharged from the outlet pipe 8 reaches the moving pressure, it will push the abutting block 20, compress the abutting spring 21, and make the sliding rod 11 slide inside the threaded sleeve 10. After the abutting block 20 is completely abutted, the gas flows into the inside of the regulating pipe 9, and finally is discharged along the exhaust pipes 22 on both sides. When no gas is discharged, the pressure on the abutting block 20 is insufficient. At this time, under the elastic action of the abutting spring 21, the abutting block 20 is restored to its initial position, so that it is in the sealing process again, so that the inside of the box body 1 will not be entered by internal dust from the side of the regulating pipe 9.

[0038] See also Figure 5-6 As an implementation method of a dust collector for epoxy resin production with a replacement component: a replacement component is arranged on the outside of the regulating pipe 9, and the replacement component includes an exhaust pipe 22, a fixing plate 23 and a filter 24. The exhaust pipe 22 is arranged on the outside of the regulating pipe 9, the fixing plate 23 is installed on the exhaust pipe 22, and the filter 24 is slidably connected to the inside of the exhaust pipe 22.

[0039] A fixing rod 25 is slidably connected to the fixing plate 23 , and the fixing rod 25 is inserted into the filter plate 24 . A tension spring 26 is sleeved on the outer side of the fixing rod 25 . A moving plate 27 is slidably connected to the fixing rod 25 , and there are two moving plates 27 .

[0040] A moving rod 28 is slidably connected between the moving plates 27 , and limiting blocks 29 are provided at both ends of the moving rod 28 . A compression spring 30 is provided between the limiting block 29 and the moving plates 27 .

[0041] More specifically, when the filtered gas is finally discharged from the exhaust pipe 22 along the regulating tube 9, it will pass through the filter 24. The filter 24 plays a filtering role for the gas. After the filter 24 has been used for a period of time, when it needs to be replaced, the movable plate 27 is manually pressed to make it move along the movable rod 28. At this time, with the cooperation of the limiting block 29, the compression spring 30 is compressed. At this time, the movable plate 27 drives the fixed rod 25 to move. At this time, the tensioning spring 26 is compressed, so that the fixed rod 25 releases the restriction process on the filter 24. At this time, the filter 24 is taken out of the exhaust pipe 22, and then a new filter 24 is placed inside the exhaust pipe 22. At this time, the movable plate 27 is loosened, so that under the action of the compression spring 30, the fixed rod 25 is driven to move on the fixed plate 23, so that it moves to the initial position, and the new filter 24 is fixed.

[0042] In summary, when the overall equipment is in use or running: when the device is in use, the gas is manually injected into the box body 1 along the air inlet pipe 18, the gas will move upward along the venturi tube 2, and the cloth bag 3 sleeved on the outside thereof will filter out the dust. When the dust needs to be processed, the electric push rod 13 is manually started to drive the connecting rod 6 at the output end to move. During the movement, the slip ring 5 is driven to slide along the outer rod 4, and cooperates with the scraper 7 arranged on the inner side of the slide rod to scrape the dust filtered out of the outside of the cloth bag 3, so that it falls on the leak plate 12 inside the box body 1, and finally discharged along the ash hopper 19. The gas storage bag 17 is manually used and the electromagnetic pulse valve 16 is opened to filter out the gas. The gas is sent into the interior of the box body 1 along the connecting pipe 15, and finally, it is discharged along the outlet pipe 8. After the gas discharged from the outlet pipe 8 reaches the moving pressure, it will push the abutting block 20, compress the abutting spring 21, and make the sliding rod 11 slide inside the threaded sleeve 10. After the abutting block 20 is completely abutted, the gas flows into the inside of the regulating pipe 9, and finally is discharged along the exhaust pipes 22 on both sides. When no gas is discharged, the pressure on the abutting block 20 is insufficient. At this time, under the elastic action of the abutting spring 21, the abutting block 20 is restored to its initial position, so that it is in the sealing process again, so that the inside of the box body 1 will not be entered by internal dust from the side of the regulating pipe 9.

[0043] When the filtered gas is finally discharged from the exhaust pipe 22 along the regulating pipe 9, it will pass through the filter 24. The filter 24 plays a filtering role for the gas. After the filter 24 has been used for a period of time, when it needs to be replaced, the movable plate 27 is manually pressed to make it move along the movable rod 28. At this time, with the cooperation of the limiting block 29, the compression spring 30 is compressed. At this time, the movable plate 27 drives the fixed rod 25 to move. At this time, the tensioning spring 26 is compressed, so that the fixed rod 25 releases the restriction process on the filter 24. At this time, the filter 24 is taken out of the exhaust pipe 22, and then a new filter 24 is placed inside the exhaust pipe 22. At this time, the movable plate 27 is loosened, so that under the action of the compression spring 30, the fixed rod 25 is driven to move on the fixed plate 23, so that it moves to the initial position, and the new filter 24 is fixed.

In the above, all fixed connections are preferably welded.
