Description

Technical Field

[0001] The utility model relates to the technical field of filter cartridge dust collectors, in particular to a filter cartridge dust collector. Background Art

[0002] The cartridge dust collector uses a cartridge as a filter element and adopts pulse jet for back-cleaning. After the dust-laden gas enters the filter chamber of the dust collector, some of the larger particles in the air flow settle downward, while the smaller and lighter particles are adsorbed to the filter material surface on the outer wall of the cartridge during Brownian diffusion. The clean gas after filtration enters the interior of the cartridge and enters the clean air chamber through the vents connected to the interior of the cartridge, and is then discharged to the outside of the machine. When using a cartridge dust collector to filter welding fumes generated during electric welding, double-protection welding, and argon arc welding, and sparks generated during laser cutting and flame cutting, it is necessary to install a spark arrester in advance to extinguish and precipitate the sparks to prevent the cartridge from burning in the subsequent cartridge dust collector, thereby avoiding paralysis of the entire dust removal system, resulting in economic losses, and even major safety accidents. The following problems exist in the existing technology:

[0003] Although the existing cartridge dust collector is equipped with a spark arrestor to capture and filter sparks, when the flue gas enters the spark arrestor, the temperature of the flue gas such as welding smoke containing sparks is relatively high. After the sparks and the extinguished particles have been in contact with the exhaust fan and the inner wall of the spark arrestor for a long time, a large amount of particles are easily attached to the blades and the inner wall of the spark arrestor. It is difficult to effectively clean these attached particles by relying on the traditional gravity falling method. After a long period of accumulation, the spark arrestor can only be disassembled and cleaned regularly, and the cleaning efficiency is low. At the same time, when the existing cartridge dust collector is performing pulse cleaning of the filter cartridge, fine dust will be blown off directly, but because the dust particles are small, a small amount of accumulation will be attached to the inner wall of the dust funnel after being blown away, and it cannot be discharged in time by its own gravity, resulting in dust residue problems.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 、 Figure 2 As shown, the utility model provides a filter cartridge dust collector, including a filter cartridge dust collector housing 1, a spark arrester body 2 is provided on the right side of the filter cartridge dust collector housing 1, the spark arrester body 2 includes a catcher housing 21, a threaded ring 22 is fixedly installed on the right side of the catcher housing 21, a conical smoke inlet 23 is threadedly installed on the inner circle of the threaded ring 22, a motor 24 is fixedly installed at the center of the left circle of the catcher housing 21, the output shaft of the motor 24 passes through the inner cavity of the catcher housing 21 and is fixedly installed with a rotating rod 25, a conical spark filter fan 26 is fixedly installed on the right end of the rotating rod 25, the conical spark filter fan 26 is located in the inner cavity of the conical smoke inlet 23, and the outer end of the rotating rod 25 Connecting rods 27 are fixedly installed on both the front and rear sides of the wall, and V-shaped stainless steel scrapers 28 are fixedly installed on the other ends of the two connecting rods 27. The two V-shaped stainless steel scrapers 28 are overlapped with the inner wall of the collector housing 21 on the side away from the connecting rods 27. A cooling particle funnel 29 that passes through its inner cavity is fixedly connected to the bottom of the collector housing 21. An L-shaped bracket 212 is fixedly installed on the bottom of the collector housing 21. The horizontal part of the L-shaped bracket 212 is fixedly connected to the right side of the filter cartridge dust collector housing 1. A smoke conveying pipe 211 that passes through its inner cavity is fixedly connected to the upper left side of the collector housing 21, and the left output end of the smoke conveying pipe 211 is fixedly connected to the top of the filter cartridge dust collector housing 1;

[0025] Welding smoke and other smoke containing sparks can enter the inner circle of the collector housing 21 through the conical smoke inlet 23. When entering, the starting motor 24 can drive the rotating rod 25 to rotate, thereby rotating the conical spark filter fan 26 in the inner circle of the conical smoke inlet 23, generating a cyclone so that the smoke enters the collector housing 21. Due to the principle of aerodynamics, the smoke collides, extinguishes, and settles in the collector housing 21. The particles attached to the inner wall of the collector housing 21 can be driven by two connecting rods 27 to drive two V-shaped stainless steel scrapers 28 to rotate and scrape the inner wall of the collector housing 21 while the rotating rod 25 drives the conical spark filter fan 26 to rotate. The unique V-shaped shape makes it convenient for the scraped particles to fall together when passing through the V-shaped stainless steel scraper 28, and then the smoke without sparks can enter the inner cavity of the filter cartridge dust collector housing 1 through the smoke pipe 211.

[0026] like Figure 3 、 Figure 4 As shown, the inner wall rear rectangular array of the filter cartridge dust collector housing 1 is provided with four filter cartridge thread grooves 11, the front rectangular array of the filter cartridge dust collector housing 1 is provided with four threaded slots 12 that pass through its inner cavity, the inner cavity of the filter cartridge dust collector housing 1 is provided with four filter cartridges 13, the front ends of the four filter cartridges 13 are fixedly installed with filter cartridge threaded front covers 131, the filter cartridge threaded front covers 131 are threadedly connected to the inner rings of the threaded slots 12, the rear end of the filter cartridge 13 is fixedly installed with a filter cartridge annular threaded rear cover 132, the filter cartridge annular threaded rear cover 132 is threadedly connected to the inner ring of the filter cartridge thread groove 11, the front end of the filter cartridge threaded front cover 131 is fixedly installed with a rotating handle 133, the bottom of the filter cartridge dust collector housing 1 is fixedly connected with a dust funnel 14 that passes through its inner cavity, the outer wall of the dust funnel 14 is fixedly installed with a vibration fixing frame 15, the lower left side of the filter cartridge dust collector housing 1 is fixedly connected with a smoke outlet pipe 16 that passes through its inner cavity, the filter cartridge dust collector housing 1 The left and right sides of the rear end are fixedly connected with air supply pipes 172, and the upper and lower output ends of the two air supply pipes 172 respectively penetrate the inner cavities of the four filter cartridge thread grooves 11 and are fixedly connected with a blowing pipe 17. A plurality of nozzles 171 are fixedly connected to the outer wall of the blowing pipe 17 in an annular array. A connecting pipe 173 is fixedly connected between the opposite surfaces of the two air supply pipes 172. The four nozzles 171 respectively penetrate the four filter cartridge annular threaded rear covers 132 to the inner cavity of the filter cartridge 13. An air bag 18 is fixedly installed at the lower part of the rear side of the filter cartridge dust collector housing 1, and an air supply pipe 181 is fixedly connected to the top of the air bag 18. The output end of the air supply pipe 181 is fixedly connected to the outer wall of the connecting pipe 173, and a pulse valve 182 is fixedly installed on the outer wall of the air supply pipe 181. A pulse controller 19 is fixedly installed at the lower left side of the rear side of the filter cartridge dust collector housing 1. The pulse controller 19 can control the start and stop of the pulse valve 182 by electrically connecting the wire to the pulse valve 182;

[0027] After the smoke gas after the sparks are filtered enters the inner cavity of the filter cartridge dust collector housing 1, the large particles can be directly discharged into the dust funnel 14, and the dust in the smoke can be adsorbed and filtered through the four filter cartridges 13, and finally the clean smoke gas after dust removal can be discharged to the outside through the smoke outlet pipe 16. At the same time, the four filter cartridges 13 can use the rotating handle 133 to rotate the filter cartridge threaded front cover 131, thereby cooperating with the threaded connection of the filter cartridge annular threaded rear cover 132 and the filter cartridge threaded groove 11, so that the filter cartridge 13 is rotated as a whole to move out of the filter cartridge dust collector housing 1, which is convenient for inspection and replacement of the filter cartridge 13. When there is a lot of dust on the filter cartridge 13, the pulse controller 19 can control the pulse valve 182 to open, so that the high-pressure gas in the air bag 18 passes through the air supply pipe 181 into the connecting pipe 173, and finally enters the air delivery pipe 172, and is sprayed out from the several nozzles 171 on the outer wall of the four blowing pipes 17, thereby blowing off the dust attached to the outer wall of the filter cartridge 13, completing the self-cleaning work.

[0028] like Figure 5 As shown, vibration cabins 151 are provided on both sides of the inner ring of the vibration fixing frame 15. Rotating motors 152 are fixedly mounted on the bottom of the inner walls of the two vibration cabins 151. Four fixing rods 153 are fixedly mounted in a circular array on the outer walls of the output shafts of the two rotating motors 152. Rubber knocking balls 154 are fixedly mounted on the other ends of the four fixing rods 153. When the rubber knocking balls 154 rotate to one side of the inner ring of the vibration fixing frame 15, they extend out of the vibration cabin 151.

[0029] After the dust is blown down, it will fall onto the inclined inner wall of the dust funnel 14. At this time, by starting the rotating motor 152 in the two vibration cabins 151 opened in the vibration fixing frame 15, the rubber knocking ball 154 at one end of the four fixing rods 153 is driven to rotate, and repeatedly knock the outer wall of the metal dust funnel 14, so that the dust funnel 14 generates high-frequency vibration, so that the dust attached to the inner wall of the dust funnel 14 can be completely fallen and discharged.

[0030] The working principle of the above-mentioned cartridge dust collector is as follows:

[0031] like Figure 1-5As shown, welding smoke and other smoke containing sparks can enter the inner circle of the capture housing 21 through the conical smoke inlet 23. When entering, the motor 24 can be started to drive the rotating rod 25 to rotate, thereby rotating the conical spark filter fan 26 located in the inner circle of the conical smoke inlet 23, generating a cyclone so that the smoke enters the capture housing 21. Due to the principle of aerodynamics, the smoke collides, extinguishes, and settles in the capture housing 21. The particles attached to the inner wall of the capture housing 21 can be used to collect the particles while the rotating rod 25 drives the conical spark filter fan 26 to rotate. Two connecting rods 27 drive two V-shaped stainless steel scrapers 28 to rotate and scrape the inner wall of the collector housing 21, and the unique V-shaped shape is used to facilitate the scraped particles to fall together when passing through the V-shaped stainless steel scraper 28, and then the smoke without sparks can pass through the smoke pipe 211 into the inner cavity of the filter cartridge dust collector housing 1. After entering, large particles can be directly discharged into the dust funnel 14, and the dust in the smoke can be adsorbed and filtered by the four filter cartridges 13. Finally, the clean smoke after dust removal can be discharged through the smoke outlet pipe 16 Outdoors, at the same time, the four filter cartridges 13 can use the rotating handle 133 to rotate the filter cartridge threaded front cover 131, thereby cooperating with the threaded connection between the filter cartridge annular threaded rear cover 132 and the filter cartridge threaded groove 11, so that the filter cartridge 13 is rotated as a whole to move out of the filter cartridge dust collector housing 1, which is convenient for the inspection and replacement of the filter cartridge 13. When there is a lot of dust on the filter cartridge 13, the pulse controller 19 can be used to control the pulse valve 182 to open, so that the high-pressure gas in the air bag 18 enters the connecting pipe 173 through the air supply pipe 181, and finally enters the air delivery pipe 172, and is discharged from the four filter cartridges 13. Several nozzles 171 on the outer wall of the blowing pipe 17 spray out, thereby blowing off the dust attached to the outer wall of the filter cartridge 13 and dropping it onto the inclined inner wall of the dust funnel 14. At this time, by starting the rotating motor 152 in the two vibration cabins 151 opened by the vibration fixing frame 15, the rubber knocking ball 154 at one end of the four fixing rods 153 is driven to rotate, and repeatedly knock on the outer wall of the metal dust funnel 14, so that the dust funnel 14 generates high-frequency vibration, so that the dust attached to the inner wall of the dust funnel 14 can be completely dropped and discharged.

[0032] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
