Description

Technical Field

[0001] The utility model relates to the technical field of natural gas, in particular to a sampling filter used for a natural gas online analysis instrument. Background Art

[0002] Natural gas is a natural gas mixture mainly composed of methane, and other common components include hydrocarbons such as ethane, propane, butane, and small amounts of nitrogen, carbon dioxide and other impurities. It is usually formed in underground natural gas fields and is an important fossil energy resource. As an important energy resource, natural gas plays an important role in energy structure adjustment and climate change mitigation. Natural gas will contain impurities during the mining process, so natural gas online analyzers are needed to analyze its data. The sampling filter of the natural gas online analyzer is a device used to sample natural gas and filter out impurities. It can ensure the accuracy and reliability of the analysis data and is widely used in natural gas exploration, production, transportation and analysis. This equipment is usually equipped with a sampling filtration system.

[0003] The sampling filter of the traditional natural gas online analyzer passes through the filter screen or other filter materials. The filter can filter out solid particles, liquid particles or other impurities in the natural gas. The filter material is the core component of the filter and is used to filter impurities in the natural gas. Common filter materials include filter screens, filter membranes, filter rods, etc. The selection depends on the particle size and impurity type to be filtered. The inlet and outlet interfaces are used to connect the natural gas pipeline system so that the natural gas can pass through the filter smoothly for sampling and filtering.

[0004] However, the natural gas inlet and outlet of traditional natural gas online analyzers are usually fixedly installed in an integrated manner. This installation method cannot disassemble the gas inlet and outlet separately. The entire device needs to be disassembled to work on each of them individually. It is very troublesome when the inlet and outlet are damaged or they need to be inspected and maintained. Usually, cumbersome operations are required to disassemble the entire instrument, which increases the difficulty of maintenance and reduces the efficiency of maintenance. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a sampling filter for a natural gas online analyzer, aiming to improve the problem that the inlet and outlet of traditional natural gas online analyzers are usually integrated and fixedly installed, and maintenance usually requires cumbersome operations, which increases the difficulty of maintenance and reduces maintenance efficiency.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sampling filter for a natural gas online analyzer, comprising an air intake bin, a side wall of the air intake bin is fixedly connected to a fixed platform, a screw is rotatably connected inside the fixed platform, a slide is threadedly connected to the outer wall of the screw, a plurality of rotating plates are rotatably connected inside the fixed platform, each of the rotating plates is provided with a slide groove, a plurality of sliding rods are rotatably connected inside the slide groove, the slide and each side wall of the rotating plate are fixedly connected to a clamping rod, and a filter assembly is arranged at the bottom of the air intake bin.

[0007] Furthermore, the filter assembly includes a filter bin, and the filter bin is arranged at the bottom of the air intake bin.

[0008] Furthermore, a plurality of connecting plates are fixedly connected inside the filter bin, and a connecting shaft is fixedly connected inside the connecting plate.

[0009] Furthermore, a sliding column is slidably connected to the outer wall of the connecting shaft, and a motor is arranged inside the filter bin.

[0010] Furthermore, a first sliding block is fixedly connected to the output end of the motor, and a first sliding shaft is slidably connected inside the first sliding block.

[0011] Furthermore, a spring is sleeved on the outer wall of the first sliding shaft, and a turntable is fixedly connected to the side wall of the first sliding shaft.

[0012] Furthermore, the side wall of the turntable is rotatably connected to a second sliding block, and the interior of the second sliding block is slidably connected to a second sliding shaft.

[0013] Furthermore, one end of the second sliding shaft is fixedly connected to the bottom of the sliding column, and a shower pipe is provided on the side wall of the second sliding block.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the utility model, the slide table is first displaced downward through the threaded connection by rotating the screw rod. This process causes multiple slide rods inside the slide table to slide inside the slide groove, thereby driving the rotating plate to rotate and change the inclination angle, and the air intake pipe is effectively fixed through the relative movement of multiple clamping rods. Through this structure, the air intake pipe of this device can be disassembled without disassembling the entire body, which reduces the difficulty of maintenance and improves the maintenance efficiency.

[0016] 2. In the utility model, the turntable can rotate on the side wall of the second slider by driving the first slider to rotate through the motor, and then the second slider drives the sliding column to slide on the outer wall of the connecting shaft. Through multiple motion relationships, the shower pipe can effectively clean the filter material inside the filter bin, thereby extending the service life and performance of the filter.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a sampling filter for a natural gas online analysis instrument, comprising an air intake bin 1, a fixed platform 2 is fixedly connected to the side wall of the air intake bin 1, a screw 3 is rotatably connected inside the fixed platform 2, a slide 6 is threadedly connected to the outer wall of the screw 3, a plurality of rotating plates 4 are rotatably connected inside the fixed platform 2, a slide groove 5 is opened inside each rotating plate 4, a plurality of sliding rods 7 are rotatably connected inside the slide 6, the sliding rod 7 is slidably connected inside the slide groove 5, a clamping rod 8 is fixedly connected to the slide 6 and the side wall of each rotating plate 4, and a filter assembly is arranged at the bottom of the air intake bin 1.

[0024] Specifically, when the screw 3 rotates inside the fixed table 2, it drives the slide 6 to move through the threaded connection with the slide 6. During this displacement process, the multiple slide rods 7 inside the slide 6 will move synchronously and slide inside the slide groove 5, so that the rotating plate 4 is subjected to force, and it can rotate inside the fixed table 2 and change its own inclination angle. The rotation of the rotating plate 4 effectively fixes the air intake pipe through the slide 6 and the multiple clamping rods 8 fixed on the surface of the rotating plate 4. The advantage of this design is that it allows the air intake pipe to be disassembled without disassembling the entire body. This significantly reduces the difficulty of maintenance and improves the efficiency of maintenance. This means that maintenance personnel can perform necessary maintenance work more quickly and easily without having to worry about complicated disassembly processes.

[0025] Reference Figure 3 The filter assembly includes a filter bin 9, which is arranged at the bottom of the air intake bin 1. A plurality of connecting plates 10 are fixedly connected inside the filter bin 9. A connecting shaft 11 is fixedly connected inside the connecting plate 10. A sliding column 12 is slidably connected to the outer wall of the connecting shaft 11. A motor 13 is arranged inside the filter bin 9. A first slider 14 is fixedly connected to the output end of the motor 13. A first sliding shaft 15 is slidably connected inside the first slider 14. A spring 16 is sleeved on the outer wall of the first sliding shaft 15. A turntable 17 is fixedly connected to the side wall of the first sliding shaft 15. A second slider 18 is rotatably connected to the side wall of the turntable 17. A second sliding shaft 19 is slidably connected inside the second slider 18. One end of the second sliding shaft 19 is fixedly connected to the bottom of the sliding column 12. A shower pipe 20 is arranged on the side wall of the second slider 18.

[0026] Specifically, the motor 13 outputs a rotational force, which drives the first slider 14 to rotate. During this process, the first sliding shaft 15 in the first slider 14 also rotates synchronously. The movement of the first sliding shaft 15 enables the turntable 17 to rotate smoothly on the side wall of the second slider 18. At the same time, the second slider 18 is subjected to tension and slides on the outer wall of the second sliding shaft 19. This coordinated movement ensures the stable rotation of the turntable 17. At this stage, the second sliding shaft 19 drives the sliding column 12 to slide on the outer wall of the connecting shaft 11. Through this multi-level movement, the spray range of the shower pipe 20 is significantly expanded. This expanded range enables the device to effectively clean the filter material inside the filter bin 9, thereby maintaining the normal operation of the device and the continuous stability of the filtering effect. The advantage of this design is that it utilizes the synergistic effect of multiple moving parts to achieve a more efficient filtering and cleaning process, thereby ensuring the reliability and performance stability of the device in long-term operation.

[0027] Working principle: when it is necessary to disassemble the air inlet of the device, first rotate the screw rod 3. While the screw rod 3 rotates inside the fixed platform 2, it drives the slide 6 to move through the threaded connection relationship with the slide 6. While the slide 6 moves, multiple slide rods 7 inside it move synchronously and slide inside the slide groove 5. At this time, the rotating plate 4 can be rotated inside the fixed platform 2 and change its own inclination angle under the force. While the rotating plate 4 rotates, the slide 6 and the multiple clamping rods 8 fixed on the surface of the rotating plate 4 can effectively fix the air intake pipe. Through this structure, the air intake pipe of this device can be disassembled without disassembling the entire body, which reduces the difficulty of maintenance and improves the maintenance efficiency. When cleaning and maintaining the filter material inside the device, start the motor 13, and the motor 13 outputs a rotating force to the first slider 14 to drive the first slider 14 to rotate. The rotation of the first slider 14 drives the first sliding shaft 15 inside it to rotate synchronously. The movement of the first sliding shaft 15 enables the turntable 17 to rotate on the side wall of the second slider 18. The second slider 18 is also subjected to tension and slides on the outer wall of the second sliding shaft 19. At this time, the second sliding shaft 19 can drive the sliding column 12 to slide on the outer wall of the connecting shaft 11. Through multiple movements, the spray range of the shower pipe 20 can be greatly improved, the filter material inside the filter bin 9 can be effectively cleaned, and the service life and performance of the filter can be extended.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
