Description

Technical Field

[0001] This utility model relates to the field of air filtration, specifically an air filter backflushing component. Background Technology

[0002] Air pollution refers to the phenomenon where certain substances enter the atmosphere due to human activities or natural processes, reaching sufficient concentrations for a sufficient period of time, and thereby endangering human comfort, health and welfare or the environment.

[0003] The pulse backflush self-cleaning air filter consists of four parts: a filter module, an outlet manifold, an electrical control system, and a support frame. After the air is filtered, dust is adsorbed onto the elements. The computer controls the sequential flow of compressed air into the filter screen using a burst-flow method, causing the filter cloth surface to expand rapidly for backflush self-cleaning. During this process, there is a certain space between the existing air jet and the filter cartridge, and the top slot of the filter cartridge is relatively small. High-speed air can easily act directly on the top end cap of the filter cartridge, causing damage to the filter cartridge and reducing its service life. Based on this, this utility model proposes an air filter backflush assembly. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-3 In this embodiment of the present invention, an air filter backflushing assembly includes a filter cartridge 1, an upper end cover 2 fixed to the top of the filter cartridge 1, and a guide mechanism 3 disposed on the upper end cover 2.

[0028] The guiding mechanism 3 includes a guiding unit and a limiting unit;

[0029] The guide unit is used to guide the airflow into the room;

[0030] The limiting unit is used to provide limits for the installation of the guide unit;

[0031] The guiding unit includes a guide cylinder 301 and a guide plate 302;

[0032] The guide tube 301 is installed inside the upper end cover 2 and extends to the outside of the upper end cover 2. The guide tube 301 is used to guide the airflow in.

[0033] The guide plate 302 is fixed to the inside of the guide cylinder 301. The guide plate 302 is used to increase the flow rate of the incoming airflow.

[0034] The limiting unit includes a docking groove 303, a support block 304, a limiting block 305, and a locking block 306;

[0035] The docking groove 303 is provided at the bottom of the guide cylinder 301, and the docking groove 303 is used to provide space for the docking of the support block 304;

[0036] The support block 304 is fixed to the inside of the upper end cover 2. The support block 304 is used to provide support for the docking of the guide cylinder 301.

[0037] The limiting block 305 is fixed to the top of the support block 304, and the limiting block 305 is used to provide space for the locking block 306 to be inserted.

[0038] The locking block 306 is fixed inside the guide cylinder 301. The locking block 306 is used to cooperate with the limiting block 305 to limit the vertical movement of the guide cylinder 301.

[0039] In this embodiment: This structure allows the guide cylinder 301 to be inserted into the top of the upper cover 2. The mating groove 303 at the bottom of the guide cylinder 301 aligns with the support block 304 on the inner side of the upper cover 2. During the insertion of the guide cylinder 301 into the upper cover 2, when the inner side of the mating groove 303 contacts the outer wall of the support block 304, the locking block 306 on the inner side of the guide cylinder 301 also enters the vertical slot at the top of the support block 304, i.e., one side of the limiting block 305. When the bottom of the locking block 306 contacts the top of the support block 304, one side of the locking block 306 also aligns with the slot of the limiting block 305. The synchronous belt is moved by rotating the guide cylinder 301. When the moving block 306 rotates, the top of the support block 304 is tilted, so the rotation of the guide cylinder 301 will also move downwards, causing the block 306 to move into the inner side of the limiting block 305, which limits the vertical movement of the guide cylinder 301. When the compressed gas above the top of the guide cylinder 301 is injected, the gas enters the interior of the filter cartridge 1 directly through the guide cylinder 301 and the guide plate 302, which facilitates quick installation and disassembly and further improves work efficiency. It should be noted that the inner diameter of the docking groove 303 is larger than the outer diameter of the support block 304, which allows the guide cylinder 301 to drive the block 306 to rotate at a certain angle.

[0040] Please refer to this carefully. Figures 1-3 The top of the support block 304 is inclined and matches the bottom of the locking block 306. The top of the support block 304 is formed with a vertical groove for the locking block 306 to be inserted. The inner side of the limiting block 305 is formed with a slot for the locking block 306 to enter axially. Multiple guide plates 302 are provided and are evenly distributed circumferentially on the inner side of the guide cylinder 301.

[0041] In this embodiment: With this structure, under the action of the inclined surface at the top of the support block 304, the locking block 306 is simultaneously located at the lowest point of the inclined surface of the support block 304 when it is inside the limiting block 305. Under the action of gravity, the locking block 306 will always be in this position, thus limiting the vertical movement of the guide cylinder.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
