Description

Technical Field

[0001] This utility model relates to the field of dust collector bags, specifically to a flat cylindrical dust collector bag with good dust collection and removal effect. Background Technology

[0002] Dust collector bags are the core component of dust collection equipment. They are usually suspended vertically at the bottom of the dust collector. The materials used to make dust collector bags are divided into twill filter media and satin filter media. Fiber filter media has good wear resistance, while satin filter media has good air permeability and elasticity. However, existing dust collector bags still have some defects in use.

[0003] Existing dust collector bags cannot be adjusted to their unfolded shape according to usage needs, making them difficult to adapt to different dust collectors and limiting their applicability. They are usually supported by a fixed inner frame or a non-adjustable outer frame, making it difficult to adjust the length-to-width ratio of the bag while maintaining an airtight top, resulting in low adjustability. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a flat cylindrical dust collector bag with good dust collection and removal effect includes a support tube, a rubber sleeve, a filter bag, and a fixing ring. The rubber sleeve is installed on the outside of the support tube, and the fixing ring is fixedly connected to the surface of the support tube. The filter bag is fixedly connected to the top of the rubber sleeve, and a support rod is provided inside the filter bag. A sliding rod is fixedly connected to the bottom of the support rod, and the connection between the sliding rod and the fixing ring is a sliding connection.

[0008] As a preferred embodiment, the surface of the fixed ring is provided with a sliding groove, and the support rod forms a sliding structure with the fixed ring through the sliding groove and the sliding rod.

[0009] As a preferred embodiment, a fixing rod is fixedly provided on the side of the slide rod, and an outer bushing is slidably installed on the outside of the fixing rod. The fixing rods are symmetrically distributed on the front and rear sides of the outer bushing. The slide rod and the support rod form a telescopic structure with the adjacent slide rod and support rod through the fixing rod and the outer bushing.

[0010] As a preferred embodiment, the outer bushing is fixedly connected to the middle of a connecting rod, and the connecting rod has a second screw hole inside.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a flat cylindrical dust collector bag with good dust collection and removal effect, which has the following beneficial effects:

[0016] 1. The distance between the two sets of sliding rods is adjusted by setting the first screw hole, the second screw hole and the bolt, thereby adjusting the length-to-width ratio of the cuboid composed of the four support rods, improving the adjustability of the device, solving the defect that the existing cloth bag cannot adjust its own opening shape according to the needs of use, and has the advantage of better use effect;

[0017] 2. The rubber sleeve on the device allows the device to maintain the overall sealing effect while changing the shape and aspect ratio of the filter bag, thus improving the device's performance and solving the problem that existing filter bags are difficult to adjust in terms of aspect ratio while keeping the top airtight.

[0023] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0024] Please see Figure 1-4 This utility model includes a support tube 1, a rubber sleeve 2, a filter bag 3, and a fixing ring 4. The rubber sleeve 2 is installed on the outside of the support tube 1, and the fixing ring 4 is fixedly connected to the surface of the support tube 1. The filter bag 3 is fixedly connected to the top of the rubber sleeve 2. A support rod 7 is provided inside the filter bag 3, and a sliding rod 6 is fixedly connected to the bottom of the support rod 7. The sliding rod 6 and the fixing ring 4 are connected by a sliding connection. The sliding rod 6 can be adjusted in position within the fixing ring 4, which facilitates subsequent adjustment by changing the aspect ratio of the cuboid formed by the two sets of sliding rods 6, thereby improving the performance of the device.

[0025] The surface of the fixed ring 4 is provided with a sliding groove 5. The support rod 7 forms a sliding structure with the fixed ring 4 through the sliding groove 5 and the sliding rod 6. The sliding structure on the device allows the support rod 7 to change the overall shape of the filter cloth, thereby improving the adjustability of the device.

[0026] A fixing rod 8 is fixedly installed on the side of the slide rod 6. An outer bushing 9 is slidably installed on the outside of the fixing rod 8. The fixing rod 8 is symmetrically distributed on the front and rear sides of the outer bushing 9. The slide rod 6 and the support rod 7 form a telescopic structure with the adjacent slide rod 6 and support rod 7 through the fixing rod 8 and the outer bushing 9. The telescopic structure on the device allows the slide rod 6 to adjust the length-to-width ratio of the cuboid formed by the four slide rods 6 when the positions of the fixing rod 8 and the outer bushing 9 change.

[0027] An overlapping rod 10 is fixedly connected in the middle of the outer bushing 9. A second screw hole 14 is provided inside the overlapping rod 10. The second screw hole 14 facilitates the subsequent adjustment of the fixed position of the overlapping rod 10, thereby changing the shape of the filter cloth support.

[0028] A connecting sleeve 11 is slidably installed on the outer side of the end of the connecting rod 10. The connecting sleeve 11 has a first screw hole 12 inside. The first screw holes 12 are evenly distributed on the surface of the connecting sleeve 11. A bolt 13 is installed between the connecting sleeve 11 and the connecting rod 10. The bolt 13 is used to adjust and fix the installation position of the connecting sleeve 11 and the connecting rod 10, thereby improving the stability of the device.

[0029] The second screw holes 14 are evenly distributed on the surface of the overlapping rod 10. The distance between two adjacent second screw holes 14 is equal to the distance between two adjacent first screw holes 12, which allows the device to adjust the fixed position of the overlapping rod 10 over a wide range, thus improving the device's performance.

[0030] The working principle of this utility model is:

[0031] like Figure 1-2As shown, when the device is in use, the filter bag 3 is supported by the support rod 7. The four-radial filter bag 3 can be supported into different shapes from the inside. When changing the shape of the filter bag 3, the rubber sleeve 2 can be connected to the support tube 1 to maintain the sealing of the top of the filter bag 3. Then, the installation of the device is completed by connecting the end of the support tube 1 to the pipe at the bottom of the dust collector.

[0032] like Figure 2-4 As shown, in actual use, the device can also adjust the length-to-width ratio of the filter bag 3 supported by the support rod 7. By moving the overlapping rod 10 in the connecting sleeve 11 to different positions in the connecting sleeve 11, the overlapping rod 10 and the connecting sleeve 11 are connected through the first screw hole 12, the second screw hole 14 and the bolt 13. During the adjustment process, the sliding rod 6 slides in the sliding groove 5 in the fixing ring 4, the distance between two adjacent sets of sliding rods 6 changes, the fixing rod 8 slides inside the outer bushing 9, and the length-to-width ratio of the cuboid formed by the four support rods 7 also changes, so that the device can change the length and width ratio of the filter bag 3 to adapt to different application scenarios.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
