Description

Technical Field

[0001] This utility model relates to the field of natural gas equipment technology, and more specifically, to a filtration device for natural gas transportation. Background Technology

[0002] Natural gas transmission filters are devices specifically designed to remove impurities and particulate matter from natural gas during transmission. They play a crucial role in the transmission and application of natural gas and are widely used in natural gas regulating stations, city gate stations, and compressor station inlets to remove solid particles and droplets, protecting the normal operation of downstream equipment. They are indispensable equipment in natural gas transmission and processing systems, ensuring the purity and safety of natural gas.

[0003] For example, Chinese Patent Publication No. CN202222581069.0 discloses a filtration device for natural gas transportation, comprising a first multi-ended pipe and a second multi-ended pipe. A first connecting flange is fixed to one side of both the first and second multi-ended pipes. A groove is formed on one side of the first connecting flange. A control valve is fixed to one side of both the first and second multi-ended pipes. A first fixing ring is fixed inside the control valve near the first multi-ended pipe, and a first filter screen is embedded inside the first fixing ring. This invention opens all control valves on the same side and closes all control valves on the other side, allowing natural gas to be transported only through the first and second multi-ended pipes. During transport, the natural gas is filtered by the first and second filter screens to ensure filtration effectiveness. The other side is closed. The natural gas pipeline is switched periodically by controlling the control valve, allowing for cleaning of the other side of the pipeline while maintaining normal natural gas transportation without requiring gas shut-off for cleaning.

[0004] However, the above technical solution requires opening all multiple control valves on the same side and closing all multiple control valves on the other side when the gas pipeline needs to be converted and used. This means that natural gas can only be transported through the first multi-head pipe and the second multi-head pipe. This requires multiple staff to operate at the same time, which is cumbersome and inconvenient. Utility Model Content

[0005] The main purpose of this utility model is to provide a filtration device for natural gas transportation, which can effectively solve the problem in the background art that when it is necessary to switch and use the gas pipeline, it is necessary to open all the multiple control valves on the same side and close all the multiple control valves on the other side, so that natural gas can only be transported through the first multi-head pipe and the second multi-head pipe. This requires multiple workers to operate at the same time, which is cumbersome and inconvenient.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A natural gas transmission filtration device includes a multi-ended pipe with two movable sleeves on one side. A gas transmission pipe is located on the side of the movable sleeves away from the multi-ended pipe, and a distribution assembly is located on one side of the gas transmission pipe. Two annular plates are located on the side of the multi-ended pipe near the movable sleeves. A rotating column is rotatably installed in the inner cavity of the multi-ended pipe near the annular plates. Several torsion springs and baffles are installed on the rotating column. A filtration component is installed inside the movable sleeves.

[0008] Preferably, the inner diameter of the annular plate is smaller than the inner diameter of the movable sleeve, and the outer wall of one side of the baffle is in contact with the outer wall of the annular plate.

[0009] Preferably, the distribution assembly includes an assembly base, an air inlet is provided on the assembly base, two air distribution grooves are provided on one side of the air inlet, a sliding groove is provided on one side of the air distribution groove, and a sliding plate is slidably disposed in the sliding groove.

[0010] Preferably, the slide plate is provided with an air groove, a threaded post is rotatably provided on one side of the slide plate, a rotating handle is provided on the threaded post, and several sealing layers are provided on the inner wall of the groove.

[0011] Preferably, the gas distribution groove is connected to the gas supply pipe, and the sliding groove passes through both gas distribution grooves.

[0012] Preferably, the threaded post is threadedly connected to the component base.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] (1) When the gas pipeline needs to be converted, the sliding plate is moved to one side by turning the rotating handle, so that the gas passage groove is connected to the gas distribution groove that needs to be circulated. At this time, the other gas distribution groove will be closed by the sliding plate, so that the natural gas can only flow in the designated gas distribution groove, thereby converting the gas pipeline. The natural gas is transported to a certain gas pipeline through the distribution component, and the gas pipeline transports the natural gas to the corresponding movable sleeve and is filtered by the filter component. Then the natural gas in the movable sleeve passes through the inner cavity of the annular plate, pushes open the baffle, and makes the baffle rotate by the rotating column, torsion spring deformation, and then the natural gas moves to the multi-head pipe. The other baffle will be blocked by the natural gas in the multi-head pipe, so that the other baffle is always in contact with the inner wall of the annular plate, so that the natural gas in the multi-head pipe will not move to the other movable sleeve. The conversion of the gas pipeline can be completed by turning one rotating handle, which is more convenient and faster. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 3 As shown, a natural gas transmission filtration device includes a multi-ended pipe 1, with two movable sleeves 2 on one side of the multi-ended pipe 1. A gas transmission pipe 3 is provided on the side of the movable sleeve 2 away from the multi-ended pipe 1, and a distribution assembly 4 is provided on one side of the gas transmission pipe 3. Two annular plates 5 are provided on the side of the multi-ended pipe 1 near the movable sleeves 2. A rotating column 6 is rotatably arranged in the inner cavity of the side of the multi-ended pipe 1 near the annular plates 5. Several torsion springs 7 and baffles 8 are provided on the rotating column 6. A filter component 9 is provided inside the movable sleeve 2.

[0022] like Figure 4 As shown, in another embodiment of the present invention, the distribution component 4 includes a component base 401, an air inlet 402 is provided on the component base 401, two air distribution grooves 403 are provided on one side of the air inlet 402, a sliding groove 404 is provided on one side of the air distribution groove 403, and a sliding plate 405 is slidably disposed in the sliding groove 404.

[0023] The slide plate 405 is provided with an air passage 406, and a threaded post 407 is rotatably provided on one side of the slide plate 405. A rotating handle 408 is provided on the threaded post 407, and a plurality of sealing layers 409 are provided on the inner wall of the slide groove 404.

[0024] When a gas pipeline needs to be switched, first turn the handle 408. Turning the handle 408 will cause the threaded post 407 to rotate. Then, the threaded post 407, which is threaded to the component base 401, will cause the slide plate 405 to move to one side. The gas passage 406 will move with the slide plate 405, so that the gas passage 406 is connected to the gas distribution channel 403 that needs to be circulated. At this time, the other gas distribution channel 403 will be closed by the slide plate 405, so that natural gas can only flow in the designated gas distribution channel 403, thereby switching the gas pipeline.

[0025] The working principle of a filtration device for natural gas transportation:

[0026] In use, natural gas is first delivered to the gas distribution trough 403 through the air inlet 402. Then, through the gas distribution trough 403, which is connected to the gas passage trough 406, the natural gas is delivered to a certain gas transmission pipe 3. The gas transmission pipe 3 delivers the natural gas to the corresponding movable sleeve 2, where it is filtered by the filter component 9. Subsequently, the natural gas in the movable sleeve 2 passes through the inner cavity of the annular plate 5, pushes open the baffle 8, causing the baffle 8 to rotate by the rotating column 6. The torsion spring 7 deforms, and then the natural gas moves into the multi-ended pipe 1. The other baffle 8 is blocked by the natural gas in the multi-ended pipe 1, so that the other baffle 8 always adheres to the inner wall of the annular plate 5, preventing the natural gas in the multi-ended pipe 1 from moving into the other movable sleeve 2. 1. Natural gas is delivered to a designated location. When the gas pipeline needs to be switched, first turn the handle 408. Turning the handle 408 drives the threaded column 407 to rotate. Then, through the threaded column 407 which is threaded to the component base 401, the slide plate 405 moves to one side. The gas passage 406 moves with the slide plate 405, so that the gas passage 406 is connected to the gas distribution 403 that needs to be circulated. At this time, the other gas distribution 403 will be closed by the slide plate 405, so that natural gas can only flow in the designated gas distribution 403, thereby switching the gas pipeline. This makes it easier to clean the filter component 9. The switching of the gas pipeline can be completed by turning the handle 408, which is more convenient and faster.

[0027] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
