Description

Technical Field

[0001] The utility model relates to the technical field of industrial filter cloth, and particularly relates to a multi-level industrial filter cloth. Background Art

[0002] The multi-level industrial filter cloth is usually made of natural fibers (such as cotton, linen, etc.) and synthetic fibers (such as polyester, polypropylene, nylon, etc.) through a weaving process. Its structural feature lies in the multi-layer design, and each layer of filter cloth may have different materials, densities, thicknesses or weaving methods to adapt to different filtration environments and requirements. This multi-layer structure enables the filter cloth to more effectively intercept and remove impurities such as solid particles and suspended matters, improving the filtration accuracy and efficiency.

[0003] The existing multi-level industrial filter cloth cannot adjust the filtration accuracy as needed, resulting in certain limitations in its use. If it is necessary to adjust the filtration accuracy according to different working conditions or material characteristics, the only option is often to replace the filter cloth, which not only increases the operating cost but also may affect the production efficiency and continuity. For this reason, a multi-level industrial filter cloth is proposed. Summary of the Utility Model

[0025] Such asFigures 1 to 6 As shown in the figure, a multi-level industrial filter cloth includes a frame body 1. Strip-shaped grooves 2 are formed on both side walls inside the frame body 1 that are symmetric to each other. A rotatable rotating shaft 3 is movably installed inside each strip-shaped groove 2. A filter cloth strip 4 is arranged inside the frame body 1. The filter cloth strip 4 is formed by sequentially splicing filter cloths with different mesh numbers. Both ends of the filter cloth strip 4 are respectively wound around the two rotating shafts 3. A rotating assembly 5 is arranged on one side of the frame body 1 for driving the two rotating shafts 3 to rotate or brake. It should be noted that when it is necessary to adjust the filtration accuracy according to different working conditions or material characteristics, the staff only needs to control the rotating assembly 5, so that one rotating shaft 3 winds up the filter cloth strip 4, and the other rotating shaft 3 unwinds the filter cloth strip 4, so that the mesh number of the filter cloth strip 4 placed in the hollow area inside the frame body 1 meets the screening requirements. Then, by controlling the rotating assembly 5, the two rotating shafts 3 are fixed at the current angle and stop rotating. Finally, the frame body 1 is installed at the designated position of the filtering equipment. Since the filter cloth strip 4 is formed by sequentially splicing filter cloths with different mesh numbers, as long as the mesh number of the filter cloth strip 4 placed in the hollow area inside the frame body 1 meets the screening requirements, the purpose of adjusting the filtration accuracy can be achieved.

[0026] As Figure 1 shown in Figure 2 As shown in the figure, the rotating assembly 5 includes a rectangular groove 501. A rectangular groove 501 is formed on one side wall of the frame body 1. Two circular plates 502 that rotate coaxially with the two rotating shafts 3 are movably installed inside the rectangular groove 501. Clamping blocks 503 are respectively fixedly installed on both sides of the rectangular groove 501 that are far away from each other. Two square blocks 504 are fixedly installed inside the rectangular groove 501. A bolt 505 is threadedly connected to each square block 504. The tail end of each bolt 505 is connected to a clamping block 506 through a bearing member. A hand-held rod 507 is fixedly installed on the side of each circular plate 502 facing away from the adjacent rotating shaft 3. It should be noted that by holding the hand-held rod 507 and rotating it, the corresponding circular plate 502 can be driven to rotate. When the circular plate 502 rotates, the corresponding rotating shaft 3 will be driven to rotate. By controlling the rotation directions of the two circular plates 502, the two rotating shafts 3 can be respectively wound up or unwound. Then, rotate the two bolts 505. The two bolts 505 respectively drive the corresponding clamping blocks 506 to approach the adjacent circular plates 502. Each circular plate 502 is clamped by the adjacent clamping block 506 and clamping block 503. At this time, the circular plate 502 will be braked and can no longer continue to rotate, so that the two rotating shafts 3 are also fixed at the current angle and no longer rotate.

[0027] As Figure 1 shown in Figure 2As shown, a rectangular frame 6 is fixedly installed at the lower part inside the frame body 1, a fixed frame 7 is arranged at the upper part inside the frame body 1, four grooves 8 are formed at the top of the frame body 1, a first threaded groove 9 is formed at the bottom of each groove 8, an installation block 10 is arranged inside each groove 8, each installation block 10 is fixedly connected with the fixed frame 7, a first bolt 11 is threadedly connected to each installation block 10, and the tail end of each first bolt 11 is threadedly connected into the adjacent first threaded groove 9. It should be noted that when the tail end of each first bolt 11 is threadedly connected into the adjacent first threaded groove 9, the fixed frame 7 and the rectangular frame 6 can be close to each other to clamp and fix the filter cloth strip 4, preventing the filter cloth strip 4 from deforming due to impact when filtering the fluid.

[0028] As Figure 3 , Figure 4 shown, strip-shaped rods 12 are fixedly installed on the inner wall surfaces on both sides inside the frame body 1, a plurality of guide wheels 13 evenly distributed at equal intervals are fixedly installed at the bottom of each strip-shaped rod 12, and notches 20 are formed at the bottom of the fixed frame 7 corresponding to the positions of the two strip-shaped rods 12. It should be noted that when the filter cloth strip 4 is pulled, wound or unwound, the guide wheels 13 can rotate synchronously, and at the same time, the guide wheels 13 and the rectangular frame 6 can cooperate to play a certain clamping effect on the edge of the filter cloth strip 4.

[0029] As Figure 1 shown, trapezoidal grooves 14 are formed on the outer wall surfaces on both sides of the frame body 1, a trapezoidal rod 15 is movably installed inside each trapezoidal groove 14, a sealing rod 16 is arranged on one side of the frame body 1, each trapezoidal rod 15 is fixedly connected with the sealing rod 16, a second bolt 17 is threadedly connected to each trapezoidal rod 15, a second threaded groove 18 is formed at the inner bottom surface of each trapezoidal groove 14, and the tail end of each second bolt 17 is threadedly connected into the adjacent second threaded groove 18. It should be noted that installing the sealing rod 16 on the side of the frame body 1 can protect the structure in the rotating assembly 5. Turning each second bolt 17 out of the corresponding second threaded groove 18 can disassemble the sealing rod 16 from the frame body 1, and the sealing rod 16 can also drive the two trapezoidal rods 15 to slide out of the corresponding trapezoidal grooves 14 respectively.

[0030] As Figure 5 shown, a rubber pad 19 is fixedly installed at the bottom of the fixed frame 7, and the rubber pad 19 is made of elastic rubber material. It should be noted that the rubber pad 19 increases the friction force, so as to more stably clamp the filter cloth strip 4 by using the rectangular frame 6 and the fixed frame 7.

[0031] In summary:

[0032] When it is necessary to adjust the filtration accuracy according to different working conditions or material characteristics, the staff only need to control the rotating assembly 5, so that one rotating shaft 3 winds the filter cloth strip 4, and the other rotating shaft 3 unwinds the filter cloth strip 4, so that the mesh number of the filter cloth strip 4 placed in the hollow area inside the frame body 1 meets the screening requirements. Then, by controlling the rotating assembly 5, the two rotating shafts 3 are fixed at the current angle and stop rotating. Finally, the frame body 1 is installed at the designated position of the filtration equipment. Since the filter cloth strip 4 is composed of filter cloths with different mesh numbers spliced in sequence, as long as the mesh number of the filter cloth strip 4 placed in the hollow area inside the frame body 1 meets the screening requirements, the purpose of adjusting the filtration accuracy can be achieved.
