Description

Technical Field

[0001] This utility model relates to the field of natural gas extraction technology, specifically a natural gas filtration and cleaning structure. Background Technology

[0002] Natural gas can be called any gas that exists naturally in the natural world. For example, when extracting oil, the fluid buried deep underground is called oil, while the combustible gas is called natural gas. In petroleum geology, natural gas is usually divided into oilfield gas and gas field gas.

[0003] According to the natural gas filtration and cleaning structure disclosed in announcement number CN221628129U, a filter barrel is included; an inlet pipe is fixedly connected to the top of the outer wall of the filter barrel and is connected to the filter barrel; an outlet pipe is fixedly connected to the bottom of the outer wall of the filter barrel and is connected to the filter barrel; a filter element is fixedly connected to the inner wall of the filter barrel; a cleaning component is provided at the bottom of the filter barrel through a rotating rod, and the filter element is cleaned by the cleaning component; this utility model uses the flow of natural gas to drive the fan blades to rotate, which in turn drives the rotating rod to rotate, thereby driving a set of cleaning plates to rotate, thus preventing the accumulation of impurities. Furthermore, the rotation of the cleaning plates drives the fixed plate and brushes to rotate, allowing the brushes to clean tiny impurities during rotation. This ensures that tiny impurities and impurities in the gaps of the filter element can be better cleaned by the brushes, thus enabling the filter element to operate efficiently.

[0004] The aforementioned device uses the flow of natural gas to drive the fan blades to rotate, which in turn drives the rotating rod to rotate, thereby causing a set of cleaning plates to rotate and preventing the accumulation of impurities. It has a certain degree of practicality. According to the instruction manual, the collection box is fixed by threaded bolts. When cleaning the impurities in the collection box, the bolts need to be tightened frequently, which is cumbersome and increases the workload and time cost of maintenance. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the above-mentioned device uses the flow of natural gas to drive the fan blades to rotate, which in turn drives the rotating rod to rotate, thereby driving a set of cleaning plates to rotate, thus preventing the accumulation of impurities. This has a certain degree of practicality. According to the instruction manual, the collection box is fixed by threaded bolts. When cleaning the impurities in the collection box, it is necessary to frequently tighten the bolts, which is cumbersome and increases the workload and time cost of maintenance. This utility model provides a natural gas filter cleaning structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a natural gas filtration and cleaning structure, including a filter barrel, an inlet pipe fixedly installed at one end of the filter barrel, an outlet pipe fixedly installed at one end of the filter barrel, a mounting base fixedly installed at one end of the filter barrel, and a collection box provided at one end of the mounting base. A slot is opened at one end of the mounting base, and a cavity is opened at the top of the slot. A sliding rod is slidably connected inside the cavity, and a return spring is sleeved on the outer periphery of the sliding rod. A limit block is fixedly installed at the bottom end of the sliding rod. A through groove is opened at one end of the collection box, and a connecting rod is slidably connected inside the through groove. A limit block is fixedly installed outside the through groove through the connecting rod. A connecting spring is fixedly installed inside the through groove and on the outer periphery of the connecting rod.

[0007] As a further embodiment of this utility model: a pushing block is slidably connected to one end of the connecting rod and located on the outer periphery of the collection box, and a connecting spring is fixedly installed between the pushing block and the middle of the limiting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model utilizes the interaction between the connecting rod and the sliding rod, as well as the return spring, to achieve automatic initial fixing, which is convenient to operate. The cooperation of limit block one and limit block two ensures a stable and reliable installation process. Inserting the limit rod further limits the position, effectively preventing accidental disassembly caused by accidental contact with the connecting rod during collection. This greatly enhances the stability of the connection between the collection box and the mounting base. The overall structure is simple and efficient, ensuring the stability and reliability of the natural gas filtration and cleaning structure during use.

[0015] In this invention, pushing the connecting rod causes the pushing block to compress the connecting spring two. Utilizing the tapered inclined surfaces at both ends of the pushing block, the restriction of the first pair of limiting blocks two can be easily released, allowing the collection box to be quickly separated from the mounting base. The entire disassembly process requires no complicated tools or steps, is highly efficient and labor-saving. When the collection box is pulled out, the return spring automatically resets the sliding rod, preparing it for the next installation. Attached Figure Description

[0024] Reference Figures 1 to 5 In this embodiment of the present invention, a natural gas filtration and cleaning structure includes a filter barrel 1, an inlet pipe 2 fixedly installed at one end of the filter barrel 1, an outlet pipe 3 fixedly installed at one end of the filter barrel 1, an mounting base 5 fixedly installed at one end of the filter barrel 1, and a collection box 6 provided at one end of the mounting base 5. A slot 7 is opened at one end of the mounting base 5, and a cavity 8 is opened at the top of the slot 7. A sliding rod 9 is slidably connected inside the cavity 8, and a reset spring 10 is sleeved on the outer periphery of the sliding rod 9. A limit block 11 is fixedly installed at the bottom end of the sliding rod 10. A through groove 12 is opened at one end of the collection box 6, and a connecting rod 13 is slidably connected inside the through groove 12. A limit block 2 15 is fixedly installed on the outside of the connecting rod 13 through the through groove 12. A connecting spring 14 is fixedly installed inside the through groove 12 and located on the outer periphery of the connecting rod 13.

[0025] The above scheme is adopted as follows: On one side of the filter bucket 1, a mounting base 5 is fixed. The mounting base 5 is block-shaped and made of sturdy material. A collection box 6 is set at one end of the mounting base 5 to collect impurities in the filtration process. A slot 7 is opened on the side of the mounting base 5. The cavity 8 at the top of the slot 7 is a cuboid structure. The sliding rod 9 can slide flexibly in the cavity 8. The return spring 10 sleeved on the outer periphery has good toughness. The limiting block 11 fixed at the bottom of the sliding rod 9 is block-shaped. The connecting rod 13 can slide smoothly in the through groove 12 at one end of the collection box 6. After the connecting rod 13 passes through the through groove 12, a limiting block 15 is fixedly installed on the outside. A connecting spring 14 is also fixed on the outer periphery of the connecting rod 13 in the through groove 12 to ensure the stability of the device operation.

[0026] Reference Figures 1 to 5 One end of the connecting rod 13 is slidably connected to a push block 16 located on the outer periphery of the collection box 6, and a connecting spring 17 is fixedly installed between the push block 16 and the middle of the limiting block 15. One end of the connecting rod 3 passes through the collection box 6 and a limiting slot 18 is opened on the outer periphery, and a limiting rod 19 for limiting is inserted into the top of the limiting slot 18.

[0027] The above scheme is adopted as follows: After the connecting rod 13 passes through one end of the collection box 6, a push block 16 is sleeved on its outer periphery. The push block 16 is annular, and its inner diameter is adapted to the connecting rod 13 so that it can slide smoothly along the rod. A connecting spring 17 is fixedly installed in the middle of the push block 16 and the limiting block 15. The connecting spring 17 has good elasticity. The two sides of the push block 16 are tapered slopes. In addition, a slender limiting slot 18 is opened on the outer periphery of one end of the connecting rod 13 that passes through the collection box 6. The top of the limiting slot 18 is tightly inserted into the limiting rod 19 to stabilize the position of the connecting rod 13 and prevent it from sliding accidentally. The top diameter of the limiting rod 19 is larger than the diameter of the limiting slot 18 so that the limiting rod 19 will not fall off the top of the limiting slot 18 when limiting.

[0028] Reference Figures 1 to 5 A through groove 4 is provided at one end of the filter bucket 1 and inside the mounting base 5, and a sealing pull rod 20 is provided at one end of the collection box 6.

[0029] The above solution is adopted as follows: a through groove 4 is carefully opened at one end of the inner side of the mounting base 5 of the filter barrel 1. The groove is slender and extends along the axial direction of the filter barrel 1. The edge is polished and smooth, so as not to obstruct the passing gas or impurities. One end of the collection box 6 is connected to the sealing rod 20. The sealing rod 20 is a cylindrical rod with good sealing performance and mechanical strength. The connection between the rod and the collection box 6 is specially sealed to ensure that the gas will not leak. Pulling the sealing rod 20 can easily connect or separate the collection box 6 from the filter barrel 1, and always maintain good sealing performance.

[0030] Reference Figures 1 to 5 The filter canister 1 is equipped with a filter element 21, which is inclined. A rotating rod 22 is rotatably connected to the center of the filter element 21, and one end of the rotating rod 22 is rotatably connected to the bottom of the filter canister 1. A fan blade 23 is fixedly installed at the top of the rotating rod 22 and below the air inlet pipe 2. A cleaning brush 24 is evenly fixedly installed around the outer periphery of the rotating rod 22 and at the top of the filter element 21.

[0031] The above solution is adopted: Inside the filter barrel 1, the filter element 21 is inclinedly placed, which can effectively guide the natural gas and impurities. At the center of the filter element 21, the rotating rod 22 is rotatably connected to the rotating rod 22 through a precision bearing. The lower end of the rotating rod 22 is also firmly connected to the bottom of the filter barrel 1 through the bearing to ensure smooth rotation. At the top of the rotating rod 22, just below the air inlet pipe 2, the fan blade 23 is firmly installed. The fan blade 23 has a smooth shape. When the natural gas rushes in from the air inlet pipe 2 at high speed, it can drive the fan blade 23 and the rotating rod 22 to rotate. On the outer periphery of the rotating rod 22, at the top of the filter element 21, a cleaning brush 24 is evenly fixed around it. The bristles are soft and dense, and can clean the filter element 21 as the rotating rod 22 rotates.

[0032] The working principle of this utility model is as follows: When installing the collection box 6, align the collection box 6 with the mounting base 5. The connecting rod 13 on the collection box 6 will interact with the sliding rod 9 on the mounting base 5. When the collection box 6 approaches the mounting base 5, the connecting rod 13 will push the sliding rod 9 upward. At this time, the return spring 10 is compressed. As the collection box 6 approaches further, the second limiting block 15 on the connecting rod 13 will slide past the first limiting block 11. After the second limiting block 15 passes the first limiting block 11, the return spring 10 rebounds, causing the sliding rod 9 to slide downward. The first limiting block 11 is locked in the middle of the second limiting block 15 and the pushing block 16, thereby achieving the initial fixation of the collection box 6 and the mounting base 5. At the same time, by inserting the limiting insert 19 into the limiting slot 18 on the outer periphery of the connecting rod 13, further... The connecting rod 13 is limited to reduce the possibility of accidental disassembly of the mounting base 5 and the collection box 6 due to accidental contact with the connecting rod 13 during collection, ensuring a stable connection between the collection box 6 and the mounting base 5. When disassembling, first pull out the limiting rod 19 to release the additional limitation on the connecting rod 13, and then push the connecting rod 13. As the connecting rod 13 is pushed, it will cause the pushing block 16 to compress the connecting spring 17 and move closer to the limiting block 15, and squeeze the limiting block 11. Since the two ends of the pushing block 16 are tapered slopes, they can release the limitation of the limiting block 11 on the limiting block 15. Then the collection box 6 and the mounting base 5 can be quickly and directly separated and disassembled. During the process of pulling out the collection box 6, the return spring 10 returns to its original state, and the sliding rod 9 returns to its initial position.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
