Abstract

This utility model discloses a filter cartridge device for easy dust removal, including a telescopic cylinder, a cylinder body, and a spray gun pipe installed inside a dust collector. A conveying channel is provided in the middle of the cylinder body, and the spray gun pipe is positioned above the conveying channel. A ring is rotatably connected to the top surface of the cylinder body near its outer diameter, and multiple levers are hinged to the top surface of the cylinder body near its inner diameter. Multiple swing rods are hinged to the ring, and the swing rods are correspondingly hinged to the levers. The end of the telescopic cylinder is hinged to the inner side of the dust collector, and the output end of the telescopic cylinder is hinged to the ring. The telescopic cylinder of this easy-to-clean filter cartridge device can drive the ring on the cylinder body to rotate. The ring, through the multiple swing rods, drives the multiple levers to swing towards the spray gun pipe, so that the multiple levers engage with the spray gun pipe and block the conveying channel of the cylinder body. This prevents air leakage from the top of the conveying channel when the spray gun pipe injects air into it, improving the dust removal effect of the cylinder body.

Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, and in particular to a filter cartridge device that is easy to clean. Background Technology

[0002] Dust collector filter cartridges are the core filtration components in industrial dust collection equipment, primarily used to capture pollutants such as dust and particulate matter. During the dust collection process, the dust collector fan drives air into the filter cartridge from all sides, where the filter layer around the cartridge blocks dust, and the filtered air exits from the top of the cartridge. Therefore, after prolonged use, the dust accumulated on the filter layer needs to be cleaned; otherwise, the dust will clog the filter layer and affect the filtration effect. During cleaning, air is often sprayed into the filter cartridge from the center using a spray gun. Previously, the top surface of the filter cartridge lacked a sealed connection structure for the spray gun, allowing air to leak out and affecting the cleaning effect. Existing filter cartridges have a sealed cover to prevent air leakage, but during dust collection, the cover's prolonged sealing of the top surface and obstruction of filtered air output reduces filtration velocity and affects filtration efficiency, increasing the power and energy consumption of the dust collector fan. Therefore, a new filter cartridge structure needs to be designed to address these issues. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a telescopic cylinder for a filter cartridge device that facilitates dust removal. The cylinder can drive a ring on the cartridge to rotate. The ring drives multiple paddles to swing towards the spray gun tube via multiple swing rods, so that the multiple paddles engage with the spray gun tube and block the conveying channel of the cartridge. In this way, when the spray gun tube sprays air into the conveying channel, it can prevent air from leaking out from the top of the conveying channel, thereby improving the dust removal effect of the cartridge.

[0004] A filter cartridge device for easy dust removal includes a telescopic cylinder, a cylinder body, and a spray gun pipe disposed within a dust collector. A conveying channel is provided in the middle of the cylinder body, and the spray gun pipe is disposed above the conveying channel. A ring is rotatably connected to the top surface of the cylinder body near its outer diameter, and multiple levers are hinged to the top surface of the cylinder body near its inner diameter. Multiple swing rods are hinged to the ring, and the multiple swing rods are correspondingly hinged to the multiple levers. The end of the telescopic cylinder is hinged to the inner side of the dust collector, and the output end of the telescopic cylinder is hinged to the ring.

[0005] Preferably, a hinge seat is provided on the outer side of the ring, and the hinge seat of the ring is hinged to the output end of the telescopic cylinder.

[0006] Preferably, a plurality of limiting posts are evenly arranged around the outer diameter of the top surface of the cylinder, and a plurality of sliding grooves are evenly arranged around the circumference of the ring, with the plurality of limiting posts corresponding to the plurality of sliding grooves in a sliding connection.

[0007] Preferably, the top surface of the cylinder is provided with a plurality of hinge posts, and a plurality of levers are hinged to the plurality of hinge posts, and the plurality of levers can abut against the spray gun pipe and block the conveying channel.

[0008] Preferably, the swing arm is an arc-shaped rod, one end of the swing arm is hinged to the top surface of the cylinder through a hinge post, and the other end of the swing arm is hinged to the lever through a hinge post.

[0009] The beneficial effects of this utility model are as follows: The filter cartridge device that facilitates dust removal works in conjunction with a telescopic cylinder, a cylinder body, and a spray gun pipe. The telescopic cylinder can drive a ring on the cylinder body to rotate. The ring body drives multiple levers to swing multiple paddles toward the spray gun pipe, so that the multiple paddles engage with the spray gun pipe and block the conveying channel of the cylinder body. This prevents air from leaking out from the top of the conveying channel when the spray gun pipe sprays air into the conveying channel, thus improving the dust removal effect of the cylinder body. Furthermore, when the cylinder body is filtering and removing dust, the telescopic cylinder reverses and drives multiple paddles to separate from the spray gun pipe and open the conveying channel of the cylinder body. The air filtered by the cylinder body is output normally along the conveying channel, improving the filtration velocity and filtration efficiency, thereby reducing the power and energy consumption of the dust collector fan during operation.

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept claimed by the present invention.

[0015] like Figs. 1 to 3As shown, a filter cartridge device for easy dust removal includes a telescopic cylinder 1, a cylinder 2, and a spray gun 3 disposed inside a dust collector. A conveying channel 4 is provided in the middle of the cylinder 2, and the spray gun 3 is disposed above the conveying channel 4. A ring 5 is rotatably connected to the top surface of the cylinder 2 near the outer diameter, and multiple levers 6 are hinged to the top surface of the cylinder 2 near the inner diameter. Multiple swing rods 7 are hinged to the ring 5, and the multiple swing rods 7 are correspondingly hinged to the multiple levers 6. The end of the telescopic cylinder 1 is hinged to the inner side of the dust collector, and the output end of the telescopic cylinder 1 is hinged to the ring 5.

[0016] The working principle of the filter cartridge device for easy dust removal described in this utility model is achieved through the cooperation of the telescopic cylinder 1, the cylinder body 2, and the spray gun pipe 3. Figs. 1 to 3 As shown, a filter layer communicating with the conveying channel 4 can be installed around the cylinder 2. The filter layer can be a filter mesh layer to block dust. After air is filtered through the filter layer, it is output from the top of the conveying channel 4, and the spray gun pipe 3 is not working. The end of the telescopic cylinder 1 can be hinged to the inside of the dust collector (not shown in the figure) through the hinge seat 8. Fig. 2 As shown, when dust needs to be cleaned from the cylinder 2, the output end of the telescopic cylinder 1 extends and drives the ring 5 on the cylinder 2 to rotate counterclockwise, and the telescopic cylinder 1 swings in the opposite direction of the ring 5. Then, the ring 5 drives multiple levers 7 to drive multiple paddles 6 to swing towards the spray gun pipe 3. The multiple paddles 6 engage with the spray gun pipe 3 and block the conveying channel 4 of the cylinder 2. The spray gun pipe 3 sprays air into the conveying channel 4. The paddles 6 can prevent air from leaking out from the top of the conveying channel 4. The air in the conveying channel 4 is output from the filter layer on the filter cartridge and drives the dust to fall outward. After the filter cartridge has completed the cleaning work, the output end of the telescopic cylinder 1 extends and resets, and drives the multiple paddles 6 to separate from the spray gun pipe 3. When the cylinder 2 is filtering and removing dust, the telescopic cylinder 1 reverses direction. Multiple levers 6 are disengaged from the spray gun pipe 3 and open the conveying channel 4 of the cylinder 2, so that the filtered air of the cylinder 2 can be output normally along the conveying channel 4. This prevents the levers 6 from blocking the output of filtered air from the conveying channel 4 when the filter cartridge is working, which would affect the filtration velocity and filtration efficiency. Compared with traditional filter cartridges, the multiple levers 6 of this easy-to-clean filter cartridge device can engage with the spray gun pipe 3 and block the conveying channel 4 of the cylinder 2. When the spray gun pipe 3 sprays air into the conveying channel 4, it can prevent air from leaking out from the top of the conveying channel 4, thereby improving the dust cleaning effect of the cylinder 2. Moreover, when the cylinder 2 is filtering and removing dust, the multiple levers 6 open the conveying channel 4 of the cylinder 2, ensuring the filtration velocity and filtration efficiency while reducing the power and energy consumption of the dust collector fan.

[0017] Specifically, a hinge seat 8 is provided on the outer side of the ring 5, and the hinge seat 8 of the ring 5 is hinged to the output end of the telescopic cylinder 1. Multiple limiting posts 9 are evenly arranged circumferentially on the outer diameter of the top surface of the cylinder 2, and multiple sliding grooves 10 are evenly arranged circumferentially on the ring 5. The multiple limiting posts 9 are slidably connected to the multiple sliding grooves 10. Further, multiple hinge posts 11 are provided on the top surface of the cylinder 2, and multiple levers 6 are hinged to the multiple hinge posts 11. The multiple levers 6 can abut against the spray gun pipe 3 and block the conveying channel 4. Even further, the swing rod 7 is an arc-shaped rod. One end of the swing rod 7 is hinged to the top surface of the cylinder 2 via a hinge post 11, and the other end of the swing rod 7 is hinged to the lever 6 via a hinge post 11. Figs. 1 to 3 As shown, the output end of the telescopic cylinder 1 extends and drives the ring 5 on the cylinder 2 to rotate counterclockwise, and the entire telescopic cylinder 1 swings in the opposite direction of the ring 5. The sliding groove 10 of the ring 5 and the limiting post 9 of the cylinder 2 cooperate to rotate on the cylinder 2. Then, one end of the swing rod 7, the ring 5, moves, and the other end of the swing rod 7 drives the paddle 6 to swing towards the spray gun pipe 3. Multiple paddles 6 engage with the spray gun pipe 3 and block the conveying channel 4 of the cylinder 2. The limiting post 9 can abut against one end of the sliding groove 10 and limit the ring 5 to prevent the paddle 6 from excessively squeezing the spray gun pipe 3. The spray gun pipe 3 sprays air into the conveying channel 4. The paddle 6 can prevent air from leaking out from the top of the conveying channel 4. The air in the conveying channel 4 is output from the filter layer on the filter cartridge and drives the dust to fall outward, improving the dust cleaning effect of the cylinder 2.
