Description

Technical Field

[0001] The utility model relates to the technical field of gas management, in particular to a gas management device. Background Art

[0002] Mine gas control is a critical component of coal mine safety production. It's a systematic project that requires the integrated application of multiple technologies and management measures to ensure safe coal mine production. By continuously optimizing ventilation systems, strengthening gas extraction, implementing emergency measures, improving monitoring and control systems, and strengthening management, we can effectively reduce the risk of gas accidents and ensure safe coal mine production.

[0003] At present, when gas is extracted from coal seams, an extraction hole is first drilled in the coal seam, a screen pipe and a sealing pipe are connected in series, and then the screen pipe is inserted into the extraction hole. A sealing material is filled between the outer wall of the sealing pipe at the entrance of the extraction hole and the wall of the extraction hole to make the extraction hole a closed space. At this time, the outer end of the sealing pipe is connected to a negative pressure device, and the through holes covered with the screen pipe can be used to extract the gas (mainly gas) in the extraction hole. However, the coal ash and coal blocks in the coal seam can easily block the through holes in the screen pipe, which makes the extraction operation not only inefficient, but also sometimes requires it to be repeated, which is time-consuming and labor-intensive. Utility Model Content

[0004] The utility model aims to provide a gas treatment device to solve the technical problem of blockage of screen tube through holes in the prior art.

[0005] In order to solve the above problems, the present invention provides the following technical solutions:

[0006] A gas treatment device comprises a sieve tube with a through hole, wherein a fixed cylinder is fixedly sleeved inside the sieve tube, the fixed cylinder is provided with a sliding hole, the sliding hole is slidably connected to a push rod that is ejected outward through the through hole, a motor is coaxially fixed to the fixed cylinder, and a push block that abuts against one end of the push rod away from the sieve tube is fixedly sleeved on the movable end of the motor, and the thickness of the push block gradually decreases along the circumferential direction.

[0007] The working principle and beneficial effects of this utility model:

[0008] When extracting gas in this scheme, the top rod is located between the screen tube and the fixed tube, that is, the top rod does not block the through-hole, and the gas enters the screen tube through the through-hole and is sucked outward. When the through-hole in the screen tube is blocked by coal ash or coal lumps, the push block is driven by the motor to rotate, and the push block rotates in the direction in which its thickness gradually increases, while the top rod and the sliding hole are slidably connected, thereby limiting the top rod to slide only in the sliding hole. The top rod is squeezed outward by the push block, and the top rod moves toward the through-hole, pushing out the coal ash, coal lumps and other blockages in the through-hole. After the through-hole is unblocked, the push block is driven by the motor to rotate in the opposite direction, and the push block gradually separates from the top rod. The movable space between the top rod and the push block increases, and under the influence of gravity, the top rod automatically slides downward in the sliding hole and separates from the through-hole, and the screen tube resumes sucking gas for treatment.

[0009] This solution uses a push rod to push the blockage out to the through hole, which cleans it more thoroughly and achieves the purpose of complete dredging, thereby ensuring that the through hole is in an unobstructed state, thereby improving the gas suction effect, that is, improving the gas control effect.

[0010] Optimally, the thickness of the pushing block gradually decreases in a clockwise direction.

[0011] Optimally, there are multiple through holes, which are evenly spaced along the circumference of the screen tube. The multiple through holes increase the amount of gas suction.

[0012] Preferably, a spring is fixed between the push rod and the fixed cylinder. When the push block pushes the push rod upward, the spring is compressed, and when the push block gradually separates from the push rod, the spring returns to pull the push rod out of the through hole.

[0013] Optimally, the diameter of the push rod is equal to the diameter of the sliding hole and the diameter of the through hole. On the one hand, the push rod can completely clear the blockage in the through hole, and on the other hand, the push rod can block the sliding hole.

[0014] Optimally, the end of the ejector rod facing the through hole is provided with a tip, which is used to eject the obstruction outwards. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following is further described in detail through specific implementation methods:

[0019] The reference numerals in the drawings of the specification include: a push rod 1 , a through hole 2 , a screen tube 3 , a motor 4 , a fixing cylinder 5 , a pushing block 6 , and a spring 7 .

[0020] In the following statements, directional words such as "left", "right", "up", and "down" are all based on the directions in the diagram. In practice, if the corresponding structures are changed in the same direction based on the directions while keeping the relative positions unchanged, it will not affect the implementation of the plan.

[0021] Embodiment: A gas treatment device includes a screen tube 3 having a plurality of through holes 2, such as Figure 1 and Figure 2 As shown, this embodiment is illustrated by three through holes 2. A fixed cylinder 5 is fixedly sleeved inside the screen tube 3. The fixed cylinder 5 is provided with a sliding hole. The sliding hole is slidably connected to a push rod 1 that is ejected outward through the through hole 2. A spring 7 is fixed between the push rod 1 and the fixed cylinder 5. A motor 4 is coaxially fixed to the fixed cylinder 5. The movable end of the motor 4 is fixedly sleeved with a push block 6 that abuts the bottom of the push rod 1. The thickness of the push block 6 gradually decreases in the clockwise direction. The right end of the screen tube 3 is connected to a negative pressure device (this part of the content belongs to the prior art). The motor 4 adopts a YBB series explosion-proof motor produced by Wuxi Zion Explosion-Proof Motor Co., Ltd.

[0022] When extracting gas in this solution, the push rod 1 is located between the screen tube 3 and the fixed cylinder 5, that is, the push rod 1 does not block the through hole 2, and the gas enters the screen tube 3 through the through hole 2 and is sucked outward. When the through hole 2 in the screen tube 3 is blocked by coal ash or coal lumps, the push block 6 is driven by the motor 4 to rotate clockwise, and the push block 6 rotates in the direction of gradually increasing its thickness. The push rod 1 is slidably connected to the sliding hole, thereby limiting the push rod 1 to slide up and down in the sliding hole. The push rod 1 is squeezed outward by the push block 6, and the push rod 1 moves toward the through hole 2, and the spring 7 is compressed. Figure 3 As shown, the coal ash, coal lumps and other obstructions in the through hole 2 are pushed out of the through hole 2. After the through hole 2 is unblocked, the motor 4 drives the push block 6 to rotate in the opposite direction, and the push block 6 gradually separates from the push rod 1. The movable space between the push rod 1 and the push block 6 increases, and the compressed spring 7 returns to the state where the push rod 1 automatically slides downward in the sliding hole, separates from the through hole 2 and returns to its initial position. The screen pipe 3 then resumes suctioning the gas for treatment.

[0023] This solution uses the push rod 1 to push the blockage into the through hole 2, which cleans it more thoroughly and achieves the purpose of complete dredging, thereby ensuring that the through hole 2 is in an unobstructed state, thereby improving the gas suction effect, that is, improving the gas control effect.
