Description

Technical Field

[0001] This utility model relates to the field of filter bag technology, specifically to a multifunctional filter bag. Background Technology

[0002] Filter bags possess excellent chemical stability and heat resistance, representing the highest performance in the filter media industry and the most advanced type of commonly used filter materials, achieving high levels in filtration efficiency and precision.

[0003] Filter bags are a key component in the operation of baghouse dust collectors. Typically, cylindrical filter bags are suspended vertically inside the dust collector. When gas enters, it expands the filter bags, and dust adheres to the inner surface of the filter bags. As the amount of dust increases, the air permeability of the filter bags decreases, requiring regular cleaning. This makes them inconvenient to use and needs improvement. Utility Model Content

[0007] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a multifunctional filter bag, including a pipe and a filter bag body sleeved on the pipe, the end of the pipe is provided with a flange, the filter bag body is sleeved on the flange, and the pipe is threadedly connected with an installation component that abuts against the flange to fix the filter bag body.

[0008] The mounting component is provided with a limiting component that fits onto the outside of the filter bag body;

[0009] The mounting component is equipped with a screen cylinder that is sleeved on the outside of the limiting component.

[0010] As an improvement, the mounting component includes a first screw cylinder that is threaded to the pipe, a second screw cylinder and a third screw cylinder that are fixed on the first screw cylinder, a limiting member that is threaded to the second screw cylinder, and a screen cylinder that is threaded to the third screw cylinder.

[0011] As an improvement, the limiting member includes a limiting screw sleeve fitted onto the second screw cylinder, and the limiting screw sleeve is uniformly provided with a plurality of arc-shaped rods that wrap around the filter bag body.

[0012] As an improvement, the screen cylinder includes a screen sleeve fitted onto the third screw cylinder, and a screen fitted onto the limiting member is fixed on the screen sleeve.

[0013] As an improvement, an elastic rope is provided at the opening of the filter bag body.

[0014] (III) Beneficial Effects

[0015] The advantages of this utility model compared with the prior art are as follows:

[0016] 1. The flange, pipe and mounting parts are fitted together with the first screw to fix the filter bag body;

[0017] 2. The limiting component includes a limiting screw sleeve and an arc-shaped rod. The arc-shaped rod can support the filter bag body, so that the dust is concentrated in the filter bag body between the arc-shaped rods, and the contact position between the filter bag body and the arc-shaped rod maintains air permeability, thus extending the cleaning cycle of the filter bag body.

[0018] 3. The screen cylinder can limit and support the filter bag body to prevent the filter bag body from being torn by excessive airflow. Attached Figure Description

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] Example 1

[0026] Combined with appendix Figure 1-4A multifunctional filter bag includes a pipe 1 and a filter bag body 2 sleeved on the pipe 1. The end of the pipe 1 is provided with a flange 3, and the filter bag body 2 is sleeved on the flange 3. The pipe 1 is threadedly connected with an installation part 4 that abuts against the flange 3 to fix the filter bag body 2.

[0027] An elastic rope 14 is provided at the opening of the filter bag body 2.

[0028] The elastic rope 14 can help fix the filter bag body 2 on the flange 3, making it easier for the mounting part 4 to fix the filter bag body 2.
