Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a moisture- and oil-resistant industrial filter bag, including a support 1, a clamping plate 2 that engages with the top of the support 1, a filter bag body 3 fixedly mounted in the middle of the clamping plate 2, and a bag cage inside the filter bag body 3 to ensure its strength. Furthermore, the filter bag body 3 is treated with waterproofing and oil-repellent agents through impregnation, pre-drying, and baking, allowing the waterproofing and oil-repellent agents to dry rapidly and then adhere to the surface of the filter material fibers in a mesh-like manner, forming a protective film on the surface of the filter bag body 3. This effectively resists the penetration of moisture and oil, improving the moisture and oil resistance of the filter bag body 3. Two rotating seats 4 are fixedly mounted on both sides of the top of the support 1, and one side of each rotating seat 4 is rotatably mounted... A rectangular box 6 is fixedly installed on both sides of the top of the cover plate 5 and the clamping plate 2. A screw rod 7 is rotatably installed inside the rectangular box 6. The two ends of the screw rod 7 are threadedly connected to the movable plate 8 through the screw rod nut. One side of the movable plate 8 passes through the rectangular box 6 and is fixedly provided with an inclined block 9. The top of the cover plate 5 is provided with an inclined groove 10 that slides with the inclined block 9. Through the mutual cooperation between the inclined block 9 and the inclined groove 10, the cover plate 5 can be pressed and limited, which facilitates the limiting of the clamping plate 2, thereby enabling the filter bag body 3 to be installed quickly. An adjustment component 11 is provided on the surface of the screw rod 7. Through the setting of the adjustment component 11, the screw rod 7 can be rotated and adjusted, making it more convenient to use.

[0025] The adjusting assembly 11 includes a worm gear 1101, which is fixedly disposed in the middle of the lead screw 7. A worm 1102 is meshed above the worm gear 1101. One end of the worm 1102 is rotatably connected to the inner wall of the rectangular box 6 via a bearing. A rotating rod 1103 is fixedly disposed at one end of the worm 1102. One end of the rotating rod 1103 passes through the rectangular box 6 and is fixedly disposed with a rotating cap 1104. The surface of the rotating cap 1104 is provided with several evenly spaced anti-slip grooves 1105. The threads at both ends of the lead screw 7 are turned in opposite directions. The bottom end of the moving plate 8 is slidably connected to the bottom end of the inner wall of the rectangular box 6. With the help of the cleverly designed adjusting assembly 11, the operator only needs to rotate the rotating cap 1104 to drive the rotating rod 1103 to rotate flexibly. The rotation of the rotating rod 1103 further drives the worm 1102 to rotate synchronously. The meshing connection between the worm 1102 and the worm gear 1101 allows the lead screw 7 to be rotated and adjusted.

[0026] A sealing gasket 12 is fixedly provided at the bottom end of the card plate 2. The sealing gasket 12 is slidably connected to the support 1. The sealing gasket 12 is made of rubber. A sealing strip 14 is fixedly provided at the bottom end of the support 1. The sealing strip 14 is made of rubber. A through hole corresponding to the filter bag body 3 is opened in the middle of the sealing gasket 12. The sealing gasket 12 and the sealing strip 14 can play a sealing role and improve the dust removal efficiency of the filter bag body 3.

[0027] The card plate 2 has a moving hole 16 in the middle that moves and cooperates with the filter bag body 3. The card plate 2 has operation slots 13 on both sides of the top. The moving hole 16 facilitates the assembly and installation of the filter bag body 3, and the operation slots 13 facilitate the rotation of the rotating cap 1104, making it convenient for the staff to operate.

[0028] The surface of the support 1 is fixedly provided with four evenly spaced mounting plates 15, and each mounting plate 15 has a mounting hole in the middle. The mounting plates 15 and mounting holes provided at the support 1 facilitate the use of bolts to fix the support 1 to the inside of the dust collector.

[0029] In use, firstly, the rotating base 4 is engaged to drive the cover plate 5. Then, the filter bag body 3 passes through the support 1, causing the clamping plate 2 to engage with the support 1. Next, the cover plate 5 is flipped and reset. Then, the rotating cap 1104 drives the rotating rod 1103 to rotate, which in turn drives the worm gear 1102 to rotate. Engaging with the meshing worm wheel 1101, the lead screw 7 can be rotated for adjustment. Since the threads at both ends of the lead screw 7 turn in opposite directions, it facilitates the synchronous movement of the two moving plates 8, allowing the inclined block 9 and the inclined groove 10 to slide and fit together, thereby enabling... The cover plate 5 can be pressed and fixed, which facilitates the limiting of the clamping plate 2, thereby enabling the filter bag body 3 to be installed quickly. Then, through the mounting plate 15 and mounting holes provided at the support 1, combined with bolts, it can be fixed to the top of the inner wall of the dust collector. The sealing gasket 12 and sealing strip 14 can achieve the sealing effect, further improving the filtration effect of the filter bag body 3 itself. By applying a water-repellent and oil-resistant process to the surface of the filter bag body 3, a protective film is formed on the surface of the filter bag body 3, which effectively resists the penetration of moisture and oil, and improves the moisture and oil resistance of the filter bag body 3 itself.
