[0022] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The following is combined with Figure 1 To the attached Figure 4 And specific embodiments discuss the present invention in detail.

[0024] like Figures 1 to 4 As shown, the utility model provides a filter cloth auxiliary installation device for a filter fan, including a support platform 1. The staff first places the filter fan 2 into the filter cloth 3, and places the filter fan 2 and the filter cloth 3 on the support platform 1. The support platform 1 supports the filter fan 2 and the filter cloth 3.

[0025] A support block 11 is fixedly connected to the upper surface of the support platform 1. A first threaded rod 4 is threadedly connected to the support block 11. A pressing block 41 is rotatably connected to the end of the first threaded rod 4 near the filter fan 2. A handwheel 42 is fixedly connected to the end of the first threaded rod 4 away from the pressing block 41. When the filter cloth 3 is placed on the support platform 1, the pressing block 41 is inserted into the filter cloth 3 through the opening of the filter cloth 3, so that the pressing block 41 abuts against the side of the filter fan 2 near the support block 11.

[0026] The support platform 1 is connected to a pair of pressing assemblies 5 , which press the two corners of the opening side of the filter cloth 3 , and the pressing assemblies 5 fix the filter cloth 3 on the support platform 1 .

[0027] The staff member turns the handwheel 42, which drives the first threaded rod 4 to rotate. The first threaded rod 4 drives the pressing block 41 to move toward the side close to the filter fan 2. The pressing block 41 pushes the filter fan 2 to move toward the inside of the filter cloth 3. The pressing assembly 5 fixes the two corners of the filter cloth 3. During the process of pushing the filter fan 2 to move by the pressing block 41, the filter cloth 3 gradually fits tightly with the filter fan 2 until the filter cloth 3 and the filter fan 2 are firmly installed. After the filter cloth 3 and the filter fan 2 are firmly installed, the pressing assembly 5 releases the fixation on the filter cloth 3, and then removes the filter cloth 3 and the filter fan 2 from the support platform 1. The open side of the filter cloth 3 is sealed. In the process of firmly installing the filter cloth 3 and the filter fan 2, the staff member can complete it by turning the handwheel 42, which reduces the labor intensity of the staff and improves work efficiency.

[0028] A rubber pad 411 is fixedly connected to the side of the pressing block 41 close to the filter fan 2. The rubber pad 411 contacts the filter fan 2 and reduces the possibility of scratches on the side of the filter fan 2 close to the pressing block 41 when the pressing block 41 pushes the filter fan 2 to move.

[0029] Each clamping assembly 5 includes a first connecting rod 51 that abuts against the lower surface of the support platform 1, and a vertically arranged second connecting rod 52 is integrally formed at one end of the first connecting rod 51, and a third connecting rod 53 is integrally formed at the top of the second connecting rod 52. The third connecting rod 53 is threadedly connected to a vertically arranged second threaded rod 54, and the lower end of the second threaded rod 54 is rotatably connected to a pressure plate 55, and the lower surface of the pressure plate 55 is fixedly connected to an anti-slip pad 551, and the top of the second threaded rod 54 is fixedly connected to a handle 541.

[0030] When the filter cloth 3 needs to be fixed, the handle 541 is rotated, and the handle 541 drives the second threaded rod 54 to rotate. During the rotation of the second threaded rod 54, the pressing plate 55 moves downward, so that the pressing plate 55 presses the filter cloth 3 tightly, thereby fixing the filter cloth 3 on the support platform 1. The anti-slip pad 551 contacts the filter cloth 3, and the anti-slip pad 551 increases the stability of the pressing plate 55 when fixing the filter cloth 3.

[0031] The handle 541 is rotated in the opposite direction, and the handle 541 drives the second threaded rod 54 to rotate in the opposite direction. The second threaded rod 54 drives the pressing plate 55 to move upward, releasing the restriction on the filter cloth 3, and the filter cloth 3 and the filter fan 2 can be removed from the supporting platform 1.

[0032] The upper surface of the support platform 1 is connected to a compacting assembly 6 . After the compacting block 41 firmly mounts the filter cloth 3 and the filter fan 2 , the compacting assembly 6 compacts the upper surface of the filter cloth 3 to make the filter cloth 3 and the filter fan 2 fit more closely.

[0033] The compaction assembly 6 includes a fixed plate 61 fixedly connected to the upper surface of the support platform 1. A hydraulic cylinder 62 is fixedly connected to the side of the fixed plate 61 away from the support block 11. The piston rod of the hydraulic cylinder 62 is disposed through the fixed plate 61. The piston rod of the hydraulic cylinder 62 is fixedly connected to a support rod 63. A plurality of springs 64 are fixedly connected to the lower surface of the support rod 63. The end of the spring 64 away from the support rod 63 is fixedly connected to a support frame 65. The support frame 65 is rotatably connected to a compaction roller 66.

[0034] After the pressing block 41 firmly installs the filter cloth 3 and the filter fan 2, the piston rod of the hydraulic cylinder 62 extends, and the support rod 63 moves toward the side close to the support block 11. The support rod 63 drives the support frame 65 and the compacting roller 66 to move toward the side close to the support block 11. The compacting roller 66 abuts against the upper surface of the filter cloth 3. The compacting roller 66 contacts the upper surface of the filter cloth 3. During the rotation of the compacting roller 66, the spring 64 is compressed, causing the compacting roller 66 to compact the upper surface of the filter cloth 3, so that the filter cloth 3 and the filter fan 2 fit more closely.

[0035] After the compaction process is completed, the piston rod of the hydraulic cylinder 62 contracts, driving the support rod 63 to move to the side away from the support block 11, so that the compaction roller 66 is separated from the filter cloth 3.

[0036] A pair of vertically disposed guide rods 651 are fixedly connected to the upper surface of the support frame 65. A pair of guide holes 631 are downwardly disposed on the upper surface of the support rod 63. The guide holes 631 correspond to the guide rods 651 one-to-one, and the guide rods 651 are slidably engaged with the guide holes 631. When the spring 64 is compressed, the support frame 65 and the guide rods 651 move upward, and the guide rods 651 slide within the guide holes 631. The guide rods 651 cause the compacting roller 66 to move vertically relative to the support rod 63 when the spring 64 is compressed, so that the pressure of the spring 64 on the support frame 65 is in the vertical direction.

[0037] The implementation principle of the filter cloth auxiliary installation device of the filter fan provided by the utility model is as follows: when the filter cloth 3 is placed on the support platform 1, the pressing block 41 is inserted into the filter cloth 3 through the opening of the filter cloth 3, so that the pressing block 41 abuts against the side of the filter fan 2 close to the support block 11, and the handle 541 is rotated. The handle 541 drives the second threaded rod 54 to rotate. During the rotation of the second threaded rod 54, the pressing plate 55 is driven to move downward, so that the pressing plate 55 presses the filter cloth 3 and fixes the filter cloth 3 on the support platform 1.

[0038] The staff member rotates the handwheel 42, which drives the first threaded rod 4 to rotate. The first threaded rod 4 drives the pressing block 41 to move toward the side close to the filter fan 2. The pressing block 41 pushes the filter cloth 3 of the filter fan 2 to move inside. The pressing assembly 5 fixes the two corners of the filter cloth 3. During the process of the pressing block 41 pushing the filter fan 2 to move, the filter cloth 3 gradually fits tightly against the filter fan 2 until the filter cloth 3 and the filter fan 2 are firmly installed. After the pressing block 41 firmly installs the filter cloth 3 and the filter fan 2, the piston rod of the hydraulic cylinder 62 extends, and the support rod 63 moves toward the side close to the support block 11. The support rod 63 drives the support frame 65 and the compacting roller 66 to move toward the side close to the support block 11. The compacting roller 66 contacts the upper surface of the filter cloth 3, causing the compacting roller 66 to compact the upper surface of the filter cloth 3.

[0039] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
