Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly filter bag technology, and in particular to an environmentally friendly filter bag with controllable filtration efficiency. Background Technology

[0002] With the acceleration of industrialization and urbanization, the demand for high-efficiency filtration materials in the fields of air pollutant control and solid waste treatment is becoming increasingly urgent. Traditional environmental protection filter bags are mostly made of synthetic fibers such as polyester and polypropylene or natural fibers, and their filtration efficiency is mainly determined by fixed parameters such as fiber diameter, porosity and filter bag structure.

[0003] The pore size and filtration accuracy of traditional filter bags are fixed in the design stage, making it difficult to dynamically adjust the filtration performance according to changes in operating conditions, such as fluctuations in dust concentration and differences in particle size distribution. This can lead to premature clogging or insufficient filtration, shortening the service life and increasing maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that the filtration efficiency is usually fixed and cannot be adjusted according to actual needs. To this end, we propose an environmentally friendly filter bag with controllable filtration efficiency.

[0005] To achieve the above objectives, this application adopts the following technical solution: an environmentally friendly filter bag with controllable filtration efficiency, comprising an outer cylinder, an adjusting cylinder at the top of the outer cylinder, an inner cylinder rotatably connected to the inside of the outer cylinder, an adjusting column rotatably connected to the inside of the adjusting cylinder, a cloth bag body inside the inner cylinder, adjusting grooves at both ends of the adjusting column, a plurality of arc blocks fixedly connected to the inner diameter of the adjusting cylinder, a push block slidably connected to the inside of the adjusting groove, an insertion rod fixedly connected to the side of the push block away from the arc blocks, and a plurality of insertion holes on the outer diameter surface of the inner cylinder.

[0006] Preferably, the size of the insertion rod is adapted to the size of the insertion hole, and the surface of the insertion rod is inserted into the interior of the insertion hole.

[0007] Preferably, a storage spring is fixedly connected to the side of the push block near the insertion rod, and the side of the storage spring away from the push block is fixedly connected to the inside of the adjustment groove.

[0008] Preferably, sliding grooves are provided on both sides of the adjustment groove, and sliders are fixedly connected to both sides of the push block, with the surface of the sliders slidingly connected to the inside of the sliding grooves.

[0009] Preferably, the front end of the adjusting column is provided with a control groove, and an insertion rod is slidably connected inside the control groove. A return spring is fixedly connected to the side of the insertion rod near the inside of the control groove, and the side of the return spring away from the insertion rod is fixedly connected to the inside of the control groove. Several insertion grooves are provided on the outer diameter surface of the adjusting cylinder.

[0010] Preferably, guide grooves are provided on both sides of the control groove, and guide blocks are fixedly connected to both sides of the insertion rod, with the surface of the guide block slidingly connected to the interior of the guide groove.

[0011] Preferably, the inner wall of the adjusting cylinder is provided with two annular grooves, and two annular blocks are fixedly connected to the outer diameter surface of the adjusting column.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator adjusts the angle of the inner cylinder to control the size of the opening between the inner and outer cylinders. After adjustment, rotating the adjusting column causes the push block and the insertion rod to move synchronously, bringing the push block into contact with the arc block. When the push block moves to the thicker end of the arc block, the arc block pushes the push block to compress the storage spring, storing energy and causing the insertion rod to be inserted into the insertion hole to fix the position of the inner cylinder. This design allows the operator to adjust the angle between the outer and inner cylinders, thereby releasing the opening and adjusting the filtration efficiency. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 5 As shown, this utility model provides a technical solution: an environmentally friendly filter bag with controllable filtration efficiency, including an outer cylinder 1, an adjusting cylinder 2 at the top of the outer cylinder 1, an inner cylinder 3 rotatably connected inside the outer cylinder 1, an adjusting column 4 rotatably connected inside the adjusting cylinder 2, a cloth bag body 5 inside the inner cylinder 3, adjusting grooves 6 at both ends of the adjusting column 4, several arc blocks 7 fixedly connected to the inner diameter of the adjusting cylinder 2, a push block 8 slidably connected inside the adjusting groove 6, an insertion rod 9 fixedly connected to the side of the push block 8 away from the arc blocks 7, several insertion holes 10 opened on the outer diameter surface of the inner cylinder 3, and a storage spring 11 fixedly connected to the side of the push block 8 near the insertion rod 9. The side away from the push block 8 is fixedly connected to the inside of the adjustment groove 6. The operator adjusts the angle of the inner cylinder 3 to adjust the release size of the hole between the inner cylinder 1 and the outer cylinder 1. After adjustment, the adjustment column 4 is rotated to drive the push block 8 and the insertion rod 9 to move synchronously, and drive the push block 8 to contact the arc block 7. When the push block 8 moves to the thicker end of the arc block 7, the arc block 7 pushes the push block 8 to compress and store the energy storage spring 11, and drives the insertion rod 9 to insert into the insertion hole 10 to fix the position of the inner cylinder 3. Through the above settings, the operator can adjust the angle between the outer cylinder 1 and the inner cylinder 3, thereby achieving the function of releasing the hole and thus adjusting the filtration efficiency.

[0022] Reference Figure 4 and Figure 5 As shown, in this embodiment: the size of the insertion rod 9 is adapted to the size of the insertion hole 10, and the surface of the insertion rod 9 is inserted into the interior of the insertion hole 10. By adapting the size of the insertion rod 9 to the size of the insertion hole 10, the insertion rod 9 can be accurately embedded into the interior of the insertion hole 10, thereby achieving seamless connection between the insertion rod 9 and the insertion hole 10, further enhancing the stability and robustness of the device.

[0023] Reference Figure 3 and Figure 4 As shown in this embodiment: sliding grooves 13 are provided on both sides of the inner side of the adjusting groove 6, and sliders 12 are fixedly connected to both sides of the push block 8. The surface of the slider 12 is slidably connected to the inside of the sliding groove 13. When the operator moves the push block 8, the push block 8 drives the slider 12 to slide inside the sliding groove 13. Through the above settings, the movement of the push block 8 is more stable, avoiding the phenomenon of the push block 8 deviating or shaking during the movement, and further improving the practicality of the device.

[0024] Reference Figure 2 - Figure 4 As shown in this embodiment: the front end of the adjusting column 4 is provided with a control groove 14, and an insertion rod 15 is slidably connected inside the control groove 14. A return spring 16 is fixedly connected to the side of the insertion rod 15 near the inside of the control groove 14. The side of the return spring 16 away from the insertion rod 15 is fixedly connected to the inside of the control groove 14. Several insertion grooves 19 are provided on the outer diameter surface of the adjusting cylinder 2. When the push block 8 moves to the thickest end of the arc block 7, the insertion rod 15 is aligned with the insertion groove 19. Under the action of the return spring 16, the insertion rod 15 is quickly pushed and driven into the insertion groove 19 for fixing. Through the above setting, the adjusting column 4 is prevented from rotating inside the adjusting cylinder 2.

[0025] Reference Figure 4 As shown in this embodiment: guide grooves 17 are provided on both sides of the control groove 14, and guide blocks 18 are fixedly connected to both sides of the insertion rod 15. The surface of the guide block 18 is slidably connected to the inside of the guide groove 17. When the operator moves the insertion rod 15, the insertion rod 15 drives the guide block 18 to slide inside the guide groove 17. Through the above settings, the movement of the insertion rod 15 can be made more stable, avoiding the shaking or deviation of the insertion rod 15 during the movement, thereby improving the stability and reliability of the entire device. At the same time, the sliding connection design of the guide block 18 inside the guide groove 17 also makes the movement of the insertion rod 15 smoother, reduces the resistance during the movement, and improves work efficiency.

[0026] Reference Figure 2 and Figure 4 As shown in this embodiment: the inner wall of the adjusting cylinder 2 is provided with two annular grooves 20, and two annular blocks 21 are fixedly connected to the outer diameter surface of the adjusting column 4. When the operator rotates the adjusting column 4, the adjusting column 4 drives the annular blocks 21 to rotate inside the annular grooves 20. Through the above setting, the stability of the adjusting column 4 during rotation can be effectively increased, avoiding the adjusting column 4 from shifting or shaking during rotation, and improving the overall structural stability. At the same time, the design of the annular blocks 21 rotating inside the annular grooves 20 can also realize the smooth rotation of the adjusting column 4, reduce frictional resistance, and make the operation simpler and less labor-intensive.

[0027] Working principle: The operator adjusts the angle of the inner cylinder 3 to adjust the release size of the hole between it and the outer cylinder 1. After adjustment, rotating the adjusting column 4 drives the push block 8 and the insertion rod 9 to move synchronously, causing the push block 8 to contact the arc block 7. When the push block 8 moves to the thicker end of the arc block 7, the arc block 7 pushes the push block 8 to compress the storage spring 11, storing force and causing the insertion rod 9 to insert into the insertion hole 10 to fix the position of the inner cylinder 3. Through the above settings, the operator can adjust the angle between the outer cylinder 1 and the inner cylinder 3, thereby achieving the function of releasing the hole and adjusting the filtration efficiency. The size of the insertion rod 9 is matched with the size of the insertion hole 10, allowing the insertion rod 9 to be precisely inserted into the insertion hole 10, thus achieving a seamless connection between the insertion rod 9 and the insertion hole 10. This further enhances the stability and robustness of the device. When the operator moves the push block 8, the push block 8 drives the slider 12 to slide inside the slide groove 13. Through the above settings, the movement of the push block 8 is more stable, avoiding deviation or shaking during movement, further improving the practicality of the device. When the operator moves the push block 8 to the thickest end of the arc block 7, the insertion rod 15... The insertion slot 19 is quickly pushed by the return spring 16, causing the insertion rod 15 to be inserted into the insertion slot 19 for fixation. This design prevents the adjusting column 4 from rotating inside the adjusting cylinder 2. When the operator moves the insertion rod 15, the insertion rod 15 drives the guide block 18 to slide inside the guide groove 17. This design makes the movement of the insertion rod 15 more stable, preventing wobbling or deviation during movement, thus improving the stability and reliability of the entire device. Simultaneously, the guide block 18 slides within the guide groove 17. The internal sliding connection design makes the movement of the insertion rod 15 smoother, reduces resistance during movement, and improves work efficiency. When the operator rotates the adjusting column 4, the adjusting column 4 drives the annular block 21 to rotate inside the annular groove 20. Through the above settings, the stability of the adjusting column 4 during rotation can be effectively increased, avoiding the adjusting column 4 from shifting or shaking during rotation, and improving the overall structural stability. At the same time, the design of the annular block 21 rotating inside the annular groove 20 can also realize the smooth rotation of the adjusting column 4, reduce frictional resistance, and make operation simpler and less strenuous.
