[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Embodiment 1, refer to Figures 1 to 5The utility model provides a kind of coal mine gas extraction pipeline anti-blocking device, including box 1, box 1 bottom is equipped with box mouth 2, two groups of net plate 3 are equipped in box 1, and net plate 3 is used to carry out double filtration operation to coal dregs etc.

[0023] In the embodiment, the inner wall of the box 1 is connected with a frame 8 at one end and the other end, and the multiple frame 8s are respectively attached to one end and the other end of the corresponding net plate 3. The frame 8 is used for positioning the net plate 3 and guiding the net plate 3, which facilitates the smooth sliding of the net plate 3 out of the box mouth 2. The slide plate 4 is connected with a handrail 11, which is used to drive the slide plate 4 to pull out at the box mouth 2. The first rubber strip 9 is attached to one end and the other end of the box mouth 2, and the multiple first rubber strips 9 are in contact with the slide plate 4. The cooperation of the first rubber strip 9 and the second rubber strip 10 can seal the contact between the slide plate 4 and the box mouth 2. The box 1 is connected with a base 13 at four corners, and the pipe body 12 is connected to the external pipeline, so that the gas can be injected into the box 1 and transported through the multiple net plates 3.

[0024] The working principle of the embodiment is as follows: when using, connect the two pipe bodies 12 with the external gas extraction pipeline. After connection, when transporting gas, the gas will pass through the multiple net plates 3 of the box 1, and the solid impurities such as coal dregs carried by the gas will be filtered and intercepted by the net plate 3 to avoid blocking the pipeline. When replacing the net plate 3, rotate the block 7 and place it corresponding to the through slot 6, so that the sheet 5 can pass through the block 7, and the slide plate 4 can be pulled out of the box mouth 2. After pulling out the slide plate 4, the accumulated impurities in the box 1 will directly fall out at the box mouth 2, and the net plate 3 will be removed from the box 1 due to gravity, which saves time and effort for replacement and cleaning.

[0025] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
