Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, specifically a pulse single-unit dust collector that is easy to clean. Background Technology

[0002] A dust collector, also known as 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 the dust-laden gas enters the dust collector, 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] The published patent document CN214862106U discloses a pulse jet dust collector that facilitates dust cleaning. This patent document solves the problem of existing pulse jet dust collectors being inconvenient for dust handling by using a combination of a dust collector body, support assembly, support plate, collection mechanism, connecting pipe, housing, baffle plate, collection box, limiting ring, support ring, first limiting block, dust bag, first limiting groove, first spring, movable block, positioning box, second spring, second limiting block, third limiting block, second limiting groove, limiting rod, push plate, and third spring. However, the aforementioned patent document requires the machine to be stopped before the housing can be disassembled to clean the dust collected inside the housing, which affects work efficiency.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] Please see Figure 1-3 This utility model provides a pulse jet dust collector that is easy to clean. It includes a dust collector housing 1, with a pulse cleaning assembly installed on the upper part of one side of the housing 1. An inverted Y-shaped tee pipe 2 connects to the bottom of the housing 1. Two dust collection cylinders 3 are installed below each inverted Y-shaped tee pipe 2. Two gate valves 4 are installed on each inverted Y-shaped tee pipe 2. Fixing rings 16 are fitted and fixedly connected to the lower ends of both sides of the inverted Y-shaped tee pipe 2. Fixing rods 17 are symmetrically welded to both sides of the fixing rings 16, and insertion holes are provided on the fixing rods 17. 18, and a positioning shaft 19 is slidably connected through one side of the fixing rod 17. A spring 21 is sleeved on the positioning shaft 19, and a pull piece 22 is fixedly installed at one end of the positioning shaft 19. One end of the positioning shaft 19 is inside the insertion hole 18. The two ends of the spring 21 are respectively connected to the fixing rod 17 and the pull piece 22. A matching dust collection bag 5 is fixedly installed inside the dust collection cylinder 3, and two insertion rods 23 that match the insertion hole 18 are fixedly connected on the dust collection cylinder 3. The insertion rods 23 have positioning holes 24 that match the positioning shaft 19. In this technical solution, the positioning shaft 19 is pulled by the puller 22, which stretches the spring 21 and moves the positioning shaft 19 out of the insertion hole 18. Then, the insertion rod 23 is inserted into the insertion hole 18. When the positioning hole 24 is aligned with the positioning shaft 19, the spring force of the spring 21 drives the positioning shaft 19 to reset, so that one end of the positioning shaft 19 enters the positioning hole 24. This completes the installation of the dust collection cylinder 3, which facilitates the installation and disassembly of the dust collection cylinder 3 and makes it easier to clean the collected dust. Furthermore, the two gate valves 4 correspond to the two dust collection cylinders 3, so that the dust in the two dust collection cylinders 3 can be cleaned sequentially without stopping the machine.

[0017] In some technical solutions, such as Figure 1 and Figure 4 As shown, the pulse cleaning assembly includes an air pump 7 and several horizontal pipes 8. The air pump 7 is fixedly installed on one side of the dust collector housing 1. Several horizontal pipes 8 pass through the upper part of one side of the dust collector housing 1 and are fixedly installed to the dust collector housing 1. The output end of the air pump 7 and the end of each horizontal pipe 8 outside the dust collector housing 1 are connected to a pulse pipe 9. A pulse solenoid valve 10 is installed on the pulse pipe 9. Several nozzles 25 are equidistantly connected to the lower side of the horizontal pipes 8 inside the dust collector housing 1. A matching support plate 26 is fixedly installed on the upper side of the inside of the dust collector housing 1. Several bag filter cartridges 20 are fixedly installed through and on the support plate 26. The nozzles 25 are above the bag filter cartridges 20, and the number of nozzles 25 is equal to the number of bag filter cartridges 20. Each nozzle 25 corresponds to each bag filter cartridge 20.

[0018] In use, by opening the pulse solenoid valve 10, the air pump 7 delivers pulsed air through the pulse tube 9 and the horizontal tube 8 to the nozzle 25 and sprays it out. The pulsed air enters the bag filter cartridge 20 and sprays out the dust blocked by the bag filter cartridge 20, causing the dust to fall into the inverted Y-shaped three-way pipe 2, thus realizing the pulse cleaning function. There is no need to disassemble the bag filter cartridge 20, making it more convenient to use.

[0019] In some technical solutions, such as Figure 4 As shown, the upper and lower parts of one side of the dust collector housing 1 are respectively connected to the exhaust pipe 13 and the air inlet pipe 12. The air inlet pipe 12 is located diagonally below the support plate 26, and the exhaust pipe 13 is located diagonally above the support plate 26.

[0020] In use, gas containing dust is delivered through the intake pipe 12, and gas free of dust is output through the exhaust pipe 13.

[0021] In some technical solutions, such as Figure 1 As shown, the outer wall of the ash collection cylinder 3 has several exhaust holes 6.

[0022] When in use, the vent 6 allows the pulsed air to be discharged and the amount of dust collected in the dust collection bag 5 to be observed.

[0023] In some technical solutions, such as Figure 1 As shown, a matching cover 11 is provided on the top of the dust collector housing 1, and the cover 11 is connected to the dust collector housing 1 by bolts.

[0024] During use, the dust collector housing 1 can be easily opened through the cover 11, making maintenance convenient.

[0025] In some technical solutions, such as Figure 1 As shown, an outer frame 14 is welded to the outer wall of the dust collector housing 1, and support legs 15 are fixedly installed at the four corners of the bottom of the outer frame 14.

[0026] When in use, the dust collector is supported by the outriggers 15.

[0027] Working principle: During installation, the puller 22 pulls the positioning shaft 19, stretches the spring 21, and moves the positioning shaft 19 out of the insertion hole 18. Then, the insertion rod 23 is inserted into the insertion hole 18. When the positioning hole 24 is aligned with the positioning shaft 19, the spring force of the spring 21 drives the positioning shaft 19 to reset, so that one end of the positioning shaft 19 enters the positioning hole 24, thus completing the installation of the dust collection cylinder 3. During use, dust-containing gas is transported through the air inlet pipe 12, and the gas enters the dust collector housing 1 through the bag filter cartridge 20. The dust is finally discharged through the exhaust pipe 13 on the upper side of the interior. The dust is blocked on the outer wall of the bag filter cartridge 20. When the pulse solenoid valve 10 is opened, the air pump 7 delivers pulse air through the pulse pipe 9 and the horizontal pipe 8 to the nozzle 25 and sprays it out. The pulse air enters the bag filter cartridge 20 and sprays out the dust blocked by the bag filter cartridge 20, causing the dust to fall into the inverted Y-shaped three-way pipe 2, thus realizing the pulse cleaning function. The two gate valves 4 correspond to the two dust collection cylinders 3, so that the dust in the two dust collection cylinders 3 can be cleaned in sequence without stopping the machine.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application 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 this application should be included within the protection scope of this application.
