Description

Technical Field

[0001] The utility model relates to the field of assembled air filters, in particular to an assembled air filter. Background Art

[0002] Air filters are devices that capture dust from gas-solid two-phase flow and purify the gas through the action of porous filter materials. Air filters play an important role in improving air quality, protecting equipment, improving efficiency, and saving energy and protecting the environment.

[0003] For example, an assembled air filter disclosed in the utility model with authorization announcement number CN220633542U presses a tray to compress the compression spring, thereby driving the sleeve rod to extend into the sleeve. In this way, the height of the tray drops, thereby increasing the distance between the upper ring and the bottom ring, so that the filter element can enter between the upper ring and the bottom ring, and then the top of the filter element is inserted into the upper ring, and then the tray is loosened to allow the bottom ring to be inserted into the bottom of the filter element. The overall structure facilitates quick installation or removal of the filter element.

[0004] This prior art also has the following problems when used:

[0005] The operation of the equipment will generate vibration, and relying on the elastic force of the compression spring for connection will easily cause gaps during operation, affecting the filtering effect. Therefore, we propose an assembled air filter to solve the above problems. Utility Model Content

A cabinet door 15 is rotatably mounted on the front end of the air filter box 1, and an air outlet mesh plate 16 is fixedly mounted on the inner end of the cabinet door 15. The chassis 8 is fixedly mounted inside the air filter box 1, and the diameter of the chassis 8 is larger than the diameter of the filter element 2; the lower surface of the filter element 2 is tightly fitted with the chassis 8, and the left and right ends of the chassis 8 are rotatably mounted with limit rods 9, and the upper end of the limit rod 9 is fixedly mounted with a fine threaded rod 10, and the outer end of the fine threaded rod 10 is threadedly connected with a pressing piece 11, and the lower surface of the pressing piece 11 is tightly fitted to the upper surface of the filter element 2, and the installation is stable and reliable, and it is easy to install and disassemble, and has strong practicality;

[0028] A connecting pipe 12 is fixedly installed at the lower end of the suction pump box 3, and a sealing ring 13 is fixedly installed at the lower end of the connecting pipe 12. The sealing ring 13 is tightly fitted on the upper surface of the filter element 2. A mounting ear 14 is symmetrically installed at the upper end of the suction pump box 3, and the inner end of the mounting ear 14 is clamped and installed with the lower end of the coarse threaded rod 6. The suction pump box 3 is located on the upper side of the filter element 2, and the suction pump box 3 is installed inside the air filter box 1 through the coarse threaded rod 6. The sealing effect is good, and the tightness of the seal can be adjusted.

[0029] Specific working principle:

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when using the assembled air filter, place the filter element 2 on the upper side of the chassis 8 and in the center so that the air inlet at the upper end of the filter element 2 is aligned with the connecting pipe 12 and the sealing ring 13, then rotate the limiting rod 9 inward to a vertical state so that the pressing piece 11 is located on the upper side of the filter element 2, and then rotate the pressing piece 11 downward, and the pressing piece 11 rotates on the outer end thread of the fine threaded rod 10. When the lower surface of the pressing piece 11 is tightly fitted with the upper surface of the filter element 2, the rotation of the pressing piece 11 can be stopped. After the limiting rods 9 on both sides are limited, the filter element 2 can be installed. Then, in order to ensure the air intake filtering effect of the filter element 2 during operation, the hexagonal handle 7 can be held and rotated, and the hexagonal handle 7 drives the coarse threaded rod 6 to rotate on the top of the air filter box 1. The lower end of the coarse threaded rod 6 rotates inside the mounting ear 14, driving the mounting ear 14 and the vacuum pump box 3 to move downward, and the bellows telescopic tube 5 follows the movement and stretches, and the vacuum pump box 3 drives the connecting pipe 12 and the sealing ring 13 to move downward, so that the lower part of the sealing ring 13 is tightly fitted with the upper part of the filter element 2. The sealing ring 13 has a certain elasticity and can be adjusted according to the situation. It is easy to use. After the adjustment is completed, the cabinet door 15 is closed and it can be used. The vacuum pump inside the vacuum pump box 3 is used to extract air, and air enters from the air inlet mesh port 4, and is discharged from the air outlet mesh plate 16 after being filtered by the filter element 2. The above completes a series of operations of the assembled air filter. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
