[0001] This utility model relates to the field of filter cloth, and in particular to an improved filter cloth structure. Background Technology

[0002] Air filtration equipment is widely used in industrial, commercial, and residential environments to remove harmful substances from the air, such as dust, particulate matter, microorganisms, pollen, smoke, and other pollutants, ensuring clean air and improving indoor air quality. One of the core components of an air filtration system is the filter cloth, which plays a crucial role in the air filtration process.

[0003] Existing technologies, such as the utility model patent with publication number CN214389284U, disclose an air filtration device. This patent includes a rectangular housing, an axial flow fan, a filter bag mounting plate, and a front door panel. The axial flow fan is fixedly installed on the top of the rectangular housing. A filter bag inlet / outlet window is provided on the front side of the rectangular housing, and the front door panel is fixedly sealed to the filter bag inlet / outlet window by a door panel locking mechanism. Various filter bag mounting holes are distributed on the filter bag mounting plate, and various air filter bags are mounted on each filter bag mounting hole via filter bag mounting brackets. This air filtration device, by using the filter bag mounting brackets to mount each air filter bag, can form multiple filtration units within the rectangular housing, meeting the needs of rapid air filtration. The door panel locking mechanism allows for detachable installation of the front door panel, facilitating maintenance of the internal air filter bags, allowing for removal, cleaning, or replacement of the air filter bags.

[0004] In daily use, it has been found that when installing filter cloths into air filtration equipment, screws are traditionally used for fixing. However, screw fixing is cumbersome and requires tools to tighten, which not only increases the complexity of the installation process but also significantly reduces installation efficiency and wastes a lot of time. This inefficient fixing method not only affects the quick replacement of filter cloths but also further restricts the overall operating efficiency of air filtration equipment.

[0005] Therefore, it is necessary to provide a new and improved filter cloth structure to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this invention is to address the problem that in the existing technology, when installing filter cloth in air filtration equipment, screws are traditionally used for fixing. However, screw fixing is cumbersome and requires tools for tightening, which not only increases the complexity of the installation process but also significantly reduces installation efficiency and wastes a lot of time.

[0016] The effect achieved by the above components is that the filter screen can be easily installed or removed by setting up the auxiliary structure, which makes it easier for personnel to clean the filter screen and improve the efficiency of air filtration.

[0017] Preferably, a soft pad, which is a rubber pad, is fixedly connected to one side of the auxiliary disk.

[0018] The effect achieved by the above components is that the soft pad can prevent the auxiliary disk from directly contacting the positioning block, thus preventing the positioning block from wearing out.

[0019] Preferably, a connecting ring is fixedly connected to the arc surface of the adjusting plate, and the cross-section of the connecting ring is circular.

[0020] The effect achieved by the above components is that the connecting ring can drive the adjusting plate to rotate, thus facilitating the control of the adjusting plate.

[0036] In the embodiments of this utility model, please refer to Figure 6 and Figure 7The auxiliary structure 7 includes two insert blocks 708, which are fixedly connected to the mounting plate 2. A fixing block 707 is slidably connected to the side of each insert block 708. The fixing block 707 is fixedly connected to the filter screen 5. Two fixing holes 706 are provided on one side of the filter screen 5. Several positioning blocks 701 are fixedly connected to one side of the mounting plate 2. Each pair of positioning blocks 701 forms a group. The inner wall of each group of positioning blocks 701 is rotatably connected to the same screw 702. An adjusting plate 703 is fixedly connected to the arc surface of the screw 702. A connecting rod 704 is fixedly connected to the lower surface of the adjusting plate 703.

The connecting ring 709 can drive the adjusting plate 703 to rotate, which achieves the effect of convenient control of the adjusting plate 703.

[0037] The working principle of the improved filter cloth structure provided by this utility model is as follows: By setting the adjustment structure 6, the positioning plate 603 is first moved inside the connecting frame 601 by the anti-slip plate 609. When the positioning plate 603 moves, it will drive the connecting plate 602 and the telescopic rod 605 and the spring 606 to retract. At the same time, the insertion plate 604 will move in the connecting groove 607 of the air filtration device 1. Then, the fixed frame 3 is moved to drive the filter cloth body 4 to move, and the fixed frame 3 is placed inside the air filtration device 1. At the same time, the fixing groove 608 of the fixed frame 3 will be inserted into the insertion plate 604. Then, the anti-slip plate 609 is released. At this time, the spring 606 will drive the positioning plate 603 to move. The positioning plate 603 will then drive the insertion plate 604 to move in the connecting groove 607. The internal movement of the 07 and the fixing groove 608 continues until the insert plate 604 is inserted deep into the fixing groove 608. At this point, the fixing of the fixing frame 3 is completed. Then, the air filtration device 1 can be started, causing the fan inside the air filtration device 1 to rotate. The fan uses the filter cloth body 4 to discharge the filtered air through the filter screen 5 on one side of the mounting plate 2. The anti-slip plate 609 can increase the friction of the positioning plate 603, preventing the personnel from slipping their hands when moving the positioning plate 603. The corrugated pipe 610 can protect the spring 606, preventing foreign objects from getting stuck inside the spring 606. Since the auxiliary plate 611 is made of acrylic and is transparent, the condition of the internal parts of the connecting frame 601 can be better observed, making it convenient for personnel to replace damaged parts.

[0038] By setting the auxiliary structure 7, the filter screen 5 is first moved to move the fixing block 707, so that the fixing block 707 is inserted into the insert block 708. Then, the adjusting plate 703 is rotated with the help of the connecting ring 709, so that the adjusting plate 703 drives the screw 702 to rotate inside the positioning block 701 until the adjusting plate 703 drives the connecting rod 704 to be inserted into the fixing hole 706 of the filter screen 5. Then, the auxiliary disk 705 on the screw 702 is rotated to fix the auxiliary disk 705 to the positioning block 701. At this time, the fixing of the filter screen 5 is completed. The soft pad 710 can prevent the auxiliary disk 705 from directly contacting the positioning block 701, thus preventing the positioning block 701 from being worn. The connecting ring 709 can drive the adjusting plate 703 to rotate, thus achieving the effect of convenient control of the adjusting plate 703.

[0039] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0040] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.
