Description

Technical Field

[0001] The utility model relates to the technical field of dust removal filter bags, in particular to a dust removal filter bag with a clogging prevention function. Background Art

[0002] The dust removal filter bag is mainly used to remove dust and lint in the air. The dust removal filter bag is usually designed in a cylindrical shape. When air passes through the dust removal filter bag, dust and lint cannot pass through the filter bag and are left in the filter bag.

[0003] In the existing filter bag structure, after long-term use, a large amount of dust and other impurities will remain in the filter bag. Then, during continuous use, the ability of the filter bag to filter air will be greatly reduced. The general solution is to replace the filter bag and clean the dust in the replaced filter bag. However, in an environment where it is not convenient to replace, such as a narrow space, it is impossible to clean the dust in the filter bag well. Content of the Utility Model

[0004] The purpose of the utility model is to provide a dust removal filter bag with a clogging prevention function to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A dust removal filter bag with a clogging prevention function, including a mounting base,

[0006] An installation ring is installed at the bottom of the mounting base. The cross-section of the installation ring is L-shaped, and a clamping ring is clamped outside the installation ring. A filter bag body is installed at the bottom of the clamping ring. A lifting ring is installed at the bottom of the installation ring, and a suction channel is opened in the lifting ring;

[0007] A vertical electric push rod is installed in the mounting base and the installation ring. The output shaft of the electric push rod faces downward and is connected to the top of the lifting ring. A multi-stage telescopic pipe is installed through the mounting base and the installation ring. The top of the multi-stage telescopic pipe is connected to an external air extraction mechanism through a connecting flange, and the bottom of the multi-stage telescopic pipe is docked with the suction channel in the lifting ring.

[0008] By adopting the above technical solution, during use, the clamping ring is sleeved on the installation ring, and after the clamping ring is limited by the installation ring, the filter bag body at the bottom of the clamping ring filters the air. After long-term use, the electric push rod drives the multi-stage telescopic pipe to extend and drives the lifting ring to move downward, so that the lifting ring sucks the inner wall of the filter bag body, avoiding blockage of the filter bag body caused by too much dust accumulation.

[0009] As a further solution of the present utility model: The snap ring includes a docking head. There are two snap rings on the left and right. Docking heads are installed on one side where the two snap rings are docked with each other. An installation cavity is opened in the docking head. A telescopic rod is installed in the installation cavity. The sleeve tube of the telescopic rod is connected to the inner wall of one side of the installation cavity, and the end of the telescopic tube of the telescopic rod is connected to the inner wall of the other side of the installation cavity. A return spring is installed in the telescopic rod.

[0010] By adopting the above technical solution, when installing the snap ring, the snap rings on both sides are pulled outwards, and the telescopic rod is extended, so as to facilitate the snap ring to be sleeved on the outside of the installation ring. After the position of the snap ring is in place, the return spring is used to make the snap rings dock with each other and reset and fix on the installation ring.

[0011] As a further solution of the present utility model: Handles are installed on the side walls of the two snap rings.

[0012] By adopting the above technical solution, the design of the handle facilitates pulling the snap rings on both sides outwards.

[0013] As a further solution of the present utility model: The air suction channel is L-shaped. A brush is installed on the side wall of the lifting ring, and the brush is attached to the inner side of the filter bag body.

[0014] By adopting the above technical solution, during use, through the design of the brush, stubborn dust on the inner wall of the filter bag body can be scraped off and sucked away through the air suction channel.

[0015] Compared with the prior art, the beneficial effects of the present utility model are: The dust removal filter bag with an anti-blocking function

[0016] is provided with a lifting ring, an electric push rod and a multi-stage telescopic tube. The electric push rod is used to drive the lifting ring to descend. The external dust suction component extracts the air in the multi-stage telescopic tube, so that a negative pressure is generated in the air suction channel in the lifting ring. Then, when the lifting ring moves down, dust and lint on the inner wall of the filter bag body can be absorbed, and the bottom of the air suction channel can suck the inner bottom of the filter bag body;

[0017] In addition, the dust removal filter bag with an anti-blocking function is also provided with a snap ring. The two snap rings can be pulled apart to both sides. After being pulled apart, the return spring in the telescopic rod plays a resetting effect, which facilitates the snap ring to be fixed on the installation ring. Such a design facilitates the installation and disassembly of the filter bag body. BRIEF DESCRIPTION OF THE DRAWINGS
