Description

Technical Field

[0001] The utility model belongs to the technical field of air filters, and particularly relates to an air filter convenient for installation. Background Art

[0002] An air filter is a device that captures dust from a gas-solid two-phase flow through the action of a porous filter material and purifies the gas. It purifies the air with a low dust content and sends it into the room to ensure the process requirements of a clean room and the air cleanliness in a general air-conditioned room, and has a wide range of application places.

[0003] Most of the existing air filters adopt an integrated design. When the air filter is used for a long time, problems such as high resistance, high energy consumption, and poor filtering effect will occur. At this time, the filter element needs to be replaced. The air filter is not easy to disassemble, time-consuming and laborious. Usually, the whole air filter is replaced, which causes waste of resources and high production costs. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide an air filter convenient for installation, which effectively solves the problem that the filter element is not easy to replace.

[0005] The technical solution for solving the technical problem is: it includes an upper frame, a filter element and a lower frame. The filter element is installed between the upper frame and the lower frame. A first rubber pad is fixed around the upper frame, and a second rubber pad is fixed around the lower frame. The filter element is located between the first rubber pad and the second rubber pad. A downward convex platform is fixed around the upper frame. A frame is provided between the lower frame and the filter element. A plurality of springs are installed between the frame and the lower frame. A groove corresponding to the convex platform up and down is provided on the frame.

[0006] Preferably, the first rubber pad is located outside the convex platform.

[0007] Preferably, the second rubber pad is located outside the frame.

[0008] Preferably, a plurality of screw holes are uniformly arranged around the upper frame and the lower frame in a circumferential manner.

[0009] Preferably, a positioning pad is fixed around the filter element.

[0010] The utility model has the following advantages compared with traditional equipment: ingenious structure, convenient disassembly and assembly. The first rubber pad and the second rubber pad are aligned and fitted up and down to ensure the overall sealing performance. Combining the convex platform, the groove, the frame and the spring structure, the positioning pad around the filter element can be positioned inside the groove. When the spring is compressed, the spring effectively supports the frame, thereby ensuring that the convex platform and the groove are clamped up and down, ensuring the fixing effect of the filter element, simple operation, good stability, convenient installation of the filter element, low cost, time-saving and labor-saving, and economical and practical.

[0016] The following further details the specific embodiments of the present utility model with reference to the accompanying drawings.

[0017] Provided by Figures 1 to 4 is an air filter facilitating installation, including an upper frame 1, a filter element 2, and a lower frame 3. The filter element 2 is installed between the upper frame 1 and the lower frame 3. A first rubber pad 4 is fixed around the upper frame 1, a second rubber pad 5 is fixed around the lower frame 3. A downward - facing boss 6 is fixed around the upper frame 1. A frame 7 is provided between the lower frame 3 and the filter element 2. A plurality of springs 8 are installed between the frame 7 and the lower frame 3. Grooves 9 corresponding to the bosses 6 up and down are provided on the frame 7.

[0018] To ensure the overall sealing performance, the first rubber pad 4 is located outside the boss 6.

[0019] To ensure the sealing performance between the upper frame 1 and the lower frame 3, the second rubber pad 5 is located outside the frame 7.

[0020] To facilitate the fixing effect of the upper frame 1, the filter element 2, and the lower frame 3, a plurality of screw holes 10 are evenly provided around the circumferences of the upper frame 1 and the lower frame 3.

[0021] A positioning pad 11 is fixed around the filter element 2.

[0022] When the utility model is in use and the air filter needs to be installed, place the lower frame 3 on the workbench, place the filter element 2 above the lower frame 3, cover the positioning pad 11 on the groove 9, then cover the upper frame 1 on the filter element 2, and the boss 6 moves downward. The boss 6 presses the positioning pad 11 into the inside of the groove 9, so that the periphery of the filter element 2 is tightened and positioned. Then insert the screw into the screw hole 10 and tighten it. During the tightening process, the boss 6 continues to move downward. The boss 6 presses the positioning pad 11 downward in the groove 9. Further, the boss 6 drives the frame 7 to move downward, and the spring 8 is in a compressed state. Under the action of the spring 8, the fixing effect of the positioning pad 11 is ensured. When multiple screws are tightened in sequence, the first rubber pad 4 and the second rubber pad 5 are aligned up and down for sealing. The boss 6 is located inside the first rubber pad 4, and the frame 7 is located inside the second rubber pad 5. Further, the overall sealing effect is ensured, and air leakage is avoided. The gas passes through the upper frame 1, the filter element 2 and the lower frame 3 in sequence, and the filter element 2 effectively filters the gas. When the filter element 2 needs to be replaced, loosen the screw, separate the upper frame 1 and the lower frame 3, and the filter element 2 can be replaced. The operation is simple and the installation is convenient.

[0023] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model all belong to the protection scope of the technical solution of the utility model.
