Description

Technical Field

[0001] The utility model relates to a manual sand discharge mechanism for a shale gas elbow and belongs to the technical field of shale gas mining auxiliary equipment. Background Art

[0002] Shale gas refers to unconventional natural gas that exists in dark shale or high-carbon shale rich in organic matter and exists mainly in adsorption or free state, with methane as the main component. Shale gas has the characteristics of self-generation and self-storage, no gas-water interface, large-area continuous accumulation, low porosity and low permeability. Generally, it has no natural production capacity or low production capacity, and can only be economically exploited after production increase and transformation, and the production cycle of a single well is long.

[0003] As society's demand for clean energy continues to expand and mining technology continues to advance, shale gas, as an important unconventional natural gas resource, is experiencing a global upsurge in exploration and development.

[0004] Since shale gas contains sand, sand is easily accumulated at the elbows of the pipelines during the transportation of shale gas by pipelines, which can easily lead to blockage of the elbows over time. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a manual sand discharge mechanism for a shale gas elbow to solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution adopted by the utility model is: a manual sand discharge mechanism for a shale gas elbow, comprising a branch pipe connected to the elbow, the branch pipe and both ends of the elbow form a tee pipe, and the end of the branch pipe is provided with a blind plate.

[0007] Preferably, a curved plate is provided on the inner side of the blind plate, and the curved plate makes the pipeline inside the tee pipe for shale gas to pass through be elbow-shaped.

[0008] Preferably, the curved plate is connected to the blind plate via a fixing rod.

[0009] Preferably, the curved plate is threadedly connected to the fixing rod.

[0010] Preferably, a flange head is fixed to the outer periphery of the end of the branch pipe, and the blind plate is connected to the flange head by fastening bolts.

[0011] Preferably, a handle is fixed on the outer side wall of the blind plate.

[0012] The beneficial effects of the utility model are as follows: compared with the prior art, the utility model forms a tee pipe by adding a branch pipe at the elbow, and then uses a blind plate to seal the right end of the branch pipe, and a curved plate is arranged in the tee pipe to keep the pipeline through which shale gas passes in an elbow shape, without changing the flow state of shale gas. Sand impacts the curved plate, and after the curved plate is damaged, it is convenient to take out the curved plate for replacement, thereby preventing sand from impacting the elbow and causing perforation of the elbow. At the same time, if sand accumulates at the elbow and causes blockage, the blind plate and the curved plate can be removed to manually clean the sand inside the elbow. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a partial cross-sectional view of the overall structure of the utility model.

[0014] The reference numerals in the drawings of the specification include: branch pipe 1, flange head 2, blind plate 3, fastening bolt 4, handle 5, fixing rod 6, curved plate 7, elbow 8, external spline 9. DETAILED DESCRIPTION

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] Embodiment 1:

[0017] A manual sand discharge mechanism for shale gas elbow, such as Figure 1 As shown, it includes a branch pipe 1 horizontally connected at the elbow 8, the branch pipe 1 and the two ends of the elbow 8 form a T-shaped tee, a flange head 2 is fixed to the outer periphery of the right end of the branch pipe 1, and a blind plate 3 is arranged at the right end of the branch pipe 1. The blind plate 3 is a circular plate and its size matches the flange head 2. The blind plate 3 is connected to the flange head 2 by a fastening bolt 4; a fixing rod 6 is fixed on the left side of the blind plate 3, and a curved plate 7 is threadedly connected to the left end of the fixing rod 6. The curved plate 7 makes the pipeline inside the tee for shale gas to pass through an elbow shape; a handle 5 is fixed to the right side wall of the blind plate 3.

[0018] In this embodiment, Figure 1 As shown, an external spline 9 is provided on the inner wall of the branch pipe 1, and an internal spline cooperating with the external spline 9 is provided on the curved plate 7. The internal spline passes through the left and right ends of the curved plate 7 to form a through groove. The cooperation of the internal and external splines 9 can prevent the curved plate 7 from rotating, thereby affecting the sealing performance of the elbow 8.

[0019] By fixing the blind plate 3 at the right end of the branch pipe 1, the curved plate 7 is fixed in the tee pipe and the pipeline through which shale gas passes is kept in an elbow shape without changing the flow state of the shale gas. Sand impacts the curved plate 7, and when the curved plate 7 is damaged, it is convenient to take out the curved plate 7 for replacement. At the same time, if sand accumulates at the elbow 8 and causes blockage, the blind plate 3 and the curved plate 7 can be removed to manually clean the sand inside the elbow 8, and then the blind plate 3 and the curved plate 7 can be reset.

[0020] The above description is only a specific implementation method of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present utility model, which should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
