[0021] The utility model provides a natural gas raw gas processing device, such as Figure 1-4 As shown, the natural gas raw gas processing device includes: a raw gas pre-separator 1, the air inlet end of the raw gas pre-separator 1 is fixedly installed with an air inlet pipe; a mounting frame 2, the mounting frame 2 is fixedly installed on the raw gas pre-separator 1, and the connecting pipe at the bottom of the mounting frame 2 can be threadedly connected with the air inlet pipe; a filter box 3, the filter box 3 is rotatably installed on the mounting frame 2, both sides of the filter box 3 are provided with filter cavities 4, one side of the inner wall of the filter cavity 4 is provided with a fixing port 5, the bottom of the filter box 3 is fixedly installed with a three-way pipe 6, the two air inlet ends of the three-way pipe 6 extend to the two filter cavities 4 respectively, the air outlet end of the three-way pipe 6 is connected to the connecting pipe connected; two filter screens 7, the two filter screens 7 can be respectively arranged in the two filter chambers 4, the filter screens 7 are located above the air inlet end of the three-way pipe 6; an air inlet box 8, the air inlet box 8 is fixedly installed on the mounting frame 2, the air inlet box 8 extends into the filter box 3 and is rotatably connected to the filter box 3, the air outlet end of the air inlet box 8 is fixedly installed with a hose 9, the air outlet end of the hose 9 is fixedly installed with a fixed pipe 10, the fixed pipe 10 can enter any of the filter chambers 4 through any of the fixed ports 5; a fixing mechanism, the fixing mechanism is arranged in the fixing port 5, the fixing mechanism is used to fix the fixed pipe 10 in the fixing port 5.

[0022] In this embodiment, the device is mainly composed of a raw gas pre-separator 1, a mounting frame 2, a filter box 3, a filter screen 7, an air intake box 8 and a fixing mechanism.

[0023] The raw gas pre-separator 1 is the core of the entire processing device and is responsible for the preliminary separation of impurities in natural gas. A rotatable filter box 3 is installed on the mounting frame 2. Two independent filter chambers 4 are arranged in the filter box 3, and a filter screen 7 is arranged in each filter chamber 4. This design allows the filter box 3 to be rotated to switch to another filter chamber 4 to continue working when the filter screen 7 of one filter chamber 4 is blocked, so there is no need to stop the machine for cleaning, which greatly improves the working efficiency.

[0024] The air inlet box 8 introduces natural gas into the filter chamber 4 of the filter box 3 through the hose 9 and the fixed pipe 10. The fixing mechanism is arranged in the fixing port 5 of the filter chamber 4, and is used to fix the fixed pipe 10 in the fixing port 5, so as to ensure that the natural gas can stably enter the filter chamber 4 for filtering.

[0025] When the filter screen 7 of one filter chamber 4 is clogged, the fixing mechanism is operated to disengage the fixing pipe 10 from the current fixing port 5 and rotate it to the fixing port 5 of another filter chamber 4 for fixing, thereby realizing the rapid switching of the filter chamber 4. This design not only improves the filtering efficiency, but also avoids the decrease in production efficiency caused by stopping the machine for cleaning.

[0026] In a further preferred embodiment of the utility model, the fixing mechanism includes a rubber sleeve 11 fixedly installed on the outside of the fixing tube 10, and a fixing groove is provided on the rubber sleeve 11, and the rubber sleeve 11 can contact the fixing port 5, and a slide groove 12 is opened above the fixing port 5, and a slide rod 13 is slidably provided in the slide groove 12, and a limit plate 14 is fixedly installed at the bottom of the slide rod 13, and the limit plate 14 can extend into the fixing groove, and a first spring 15 is sleeved on the slide rod 13, and the two ends of the first spring 15 are respectively fixedly connected to the inner wall of the narrow section of the slide groove 12 and the top bulge of the slide rod 13.

[0027] In this embodiment, the rubber sleeve 11 is fixedly mounted on the outer side of the fixing tube 10 for close contact with the fixing opening 5. A fixing groove is provided on the rubber sleeve 11 for cooperating with the limiting plate 14 to fix the fixing tube 10 in the fixing opening 5.

[0028] The slide groove 12 is provided above the fixing opening 5, providing a sliding space for the slide bar 13. The design of the slide groove 12 allows the slide bar 13 to slide up and down therein.

[0029] The slide bar 13 is slidably arranged in the slide slot 12 to control the lifting and lowering of the limit plate 14. The limit plate 14 is fixedly installed at the bottom of the slide bar 13. When the slide bar 13 slides in the slide slot 12, the limit plate 14 will also move accordingly.

[0030] The limiting plate 14 can extend into the fixing groove of the rubber sleeve 11 to lock the fixing pipe 10 in the fixing opening 5. When the limiting plate 14 completely enters the fixing groove, the fixing pipe 10 is firmly fixed in the fixing opening 5.

[0031] The first spring 15 is sleeved on the slide bar 13, and its two ends are respectively fixedly connected with the narrow section inner wall of the slide slot 12 and the top bulge of the slide bar 13. The function of the first spring 15 is to provide elastic force to help the slide bar 13 and the limit plate 14 to reset.

[0032] When the fixing tube 10 needs to be fixed, the slide bar 13 is pressed downward to make the limit plate 14 enter the fixing groove of the rubber sleeve 11, and the first spring 15 is compressed. When the limit plate 14 completely enters the fixing groove, the elastic force of the first spring 15 will keep it in the fixed position, thereby ensuring the stable fixation of the fixing tube 10.

[0033] When the fixation needs to be released, it is only necessary to release the squeezing of the slide bar 13 so that it moves upward under the elastic rebound of the first spring 15, and the limit plate 14 is withdrawn from the fixing groove, and the fixing tube 10 can move freely.

[0034] In a further preferred embodiment of the utility model, a fixing rod 16 is fixedly installed on one side of the air intake box 8, and a fixing plate 17 is fixedly installed on one side of the fixing tube 10. The fixing plate 17 is slidably connected to the fixing rod 16. A second spring 18 is sleeved on the fixing rod 16, and both ends of the second spring 18 are fixedly connected to the air intake box 8 and the fixing plate 17 respectively.

[0035] In this embodiment, the fixing rod 16 is fixedly installed on one side of the air intake box 8 and serves as a track for the fixing plate 17 to slide.

[0036] The fixing plate 17 is fixedly mounted on one side of the fixing pipe 10 and is slidably connected to the fixing rod 16. The fixing plate 17 slides along the track of the fixing rod 16, thereby driving the fixing pipe 10 to move.

[0037] The second spring 18 is sleeved on the fixing rod 16, and its two ends are respectively fixedly connected to the air intake box 8 and the fixing plate 17. The function of the second spring 18 is to provide elastic force for the fixing plate 17 to ensure that the fixing pipe 10 can be stably maintained at the desired position.

[0038] When the position of the fixed tube 10 needs to be adjusted to match different filter chambers 4, the fixed plate 17 can be pushed to slide along the fixed rod 16. In this process, the second spring 18 will be compressed to balance the external force. When the external force disappears, the second spring 18 will restore its original length and push the fixed plate 17 and the fixed tube 10 back into the fixed port 5.

[0039] The design of this adjustment mechanism not only increases the flexibility of the device, making it adaptable to different working requirements, but also improves the stability of the device. Through the elastic force of the second spring 18, the fixed pipe 10 can accurately enter the fixed port 5, thereby ensuring that the natural gas can smoothly enter the filter chamber 4 for filtration.

[0040] In a further preferred embodiment of the utility model, support grooves 19 are provided on both sides of the top of the filter box 3, a support rod 20 is fixedly installed in the support groove 19, a support frame 21 is slidably installed on the support rod 20, a U-shaped frame is fixedly installed on the bottom of the support frame 21, and one side of the U-shaped frame extending out of the support groove 19 can contact the fixed plate 17.

[0041] In this embodiment, the support grooves 19 are opened on both sides of the top of the filter box 3 to provide installation space for subsequent support structures.

[0042] The support rod 20 is fixedly installed in the support groove 19, serving as a track for the sliding of the support frame 21. The design of the support rod 20 ensures that the support frame 21 can slide stably thereon.

[0043] The support frame 21 is slidably mounted on the support rod 20, and can slide left and right along the support rod 20 as needed. A U-shaped frame is fixedly mounted at the bottom of the support frame 21.

[0044] One side of the U-shaped frame extending out of the support groove 19 can contact the fixed plate 17. When the U-shaped frame is driven to slide by the support frame 21, the U-shaped frame gradually contacts the fixed plate 17 and gradually pushes the fixed plate 17 to one side, ensuring the stability and accuracy of the fixed pipe 10 during the movement.

[0045] The contact between the U-shaped frame and the fixing plate 17 provides support for the movement of the fixing tube 10, so that the fixing tube 10 can be moved to the desired position more accurately, and the fixing tube 10 can be easily driven out of the fixing port 5, so as to adjust the fixing tube 10 to different filter chambers 4.

[0046] The support frame 21 can slide on the support rod 20, so that the position of the U-shaped frame can be adjusted to meet the different usage requirements of the fixing plate 17 and the fixing pipe 10, thereby increasing the flexibility of the device.

[0047] In a further preferred embodiment of the utility model, a guide rod 22 is fixedly installed in the support frame 21, and a guide frame 23 is slidably installed on the guide rod 22, and the guide frame 23 is slidably connected to the support rod 20, the top expanded section of the slide rod 13 extends into the support groove 19 and slides in contact with the inclined surface of the guide frame 23, and a third spring 24 is sleeved on the guide rod 22, and the two ends of the third spring 24 are respectively fixedly connected to the inner wall of the support frame 21 and the guide frame 23, and sliding sleeves 25 are slidably sleeved on both sides of the filter box 3, and the guide frame 23 extends to one side outside the filter box 3 and is fixedly connected to the sliding sleeve 25, and the sliding sleeve 25 closes the top opening of the support groove 19.

[0048] In this embodiment, the guide rod 22 is fixedly installed in the support frame 21, providing a sliding track for the guide frame 23. The guide rod 22 ensures that the guide frame 23 can slide thereon stably and accurately.

[0049] The guide frame 23 is slidably mounted on the guide rod 22 and is also slidably connected to the support rod 20. This double sliding design enables the guide frame 23 to move flexibly while maintaining the stability of the structure.

[0050] The third spring 24 is sleeved on the guide rod 22, and its two ends are respectively fixedly connected to the inner wall of the support frame 21 and the guide frame 23. The third spring 24 provides a resetting elastic force for the guide frame 23, ensuring that it can automatically return to the preset position when not affected by external force.

[0051] The top enlarged section of the slide bar 13 extends into the support groove 19 and slides in contact with the inclined surface of the guide frame 23. This design cleverly utilizes the movement of the guide frame 23 to push the slide bar 13 up and down, driving the limit plate 14 away from or close to the fixed groove, thereby realizing the unlocking or locking function of the fixed pipe 10.

[0052] The sliding sleeve 25 is slidably mounted on both sides of the filter box 3 and is fixedly connected to one side of the guide frame 23 extending outside the filter box 3. The sliding sleeve 25 not only closes the top opening of the support groove 19 and enhances the sealing of the structure, but also realizes the adjustment of the position of the support frame 21 through the connection with the guide frame 23.

[0053] When it is necessary to rotate the filter box 3 to switch the filter chamber 4, it is only necessary to slide the sleeve 25 inward to make the guide frame 23 move inward along the guide rod 22. At this time, the top expanded section of the slide rod 13 will move upward along the sliding of the inclined surface of the guide frame 23, so that the limit plate 14 will gradually move away from the fixed groove, thereby loosening the fixation of the fixed tube 10, and as the guide frame 23 continues to move, the support frame 21 is driven to move inward, so that the fixed plate 17 is driven by the U-shaped frame to slide inward, and the fixed tube 10 is driven to gradually leave the fixed port 5, and then the filter box 3 can be rotated to achieve the purpose of quickly switching the filter chamber 4.

[0054] The design of the sliding sleeve 25 not only enhances the stability of the filter box 3, but also improves the sealing performance of the device by closing the top opening of the support groove 19, thereby preventing gas leakage.

[0055] The entire locking and unlocking process can be completed by simply sliding the sliding sleeve 25, which greatly simplifies the operation steps and improves work efficiency.

[0056] In a further preferred embodiment of the utility model, positioning rods 26 are provided on both sides of the sliding sleeve 25, and threaded rods 27 are fixedly installed on the positioning rods 26. Positioning grooves 28 are opened on both sides of the filter box 3, and the bottom of the positioning groove 28 is provided with threads. The threaded rods 27 can extend into the positioning groove 28 and can be threadedly connected to the bottom thereof.

[0057] In this embodiment, the positioning rods 26 are arranged on both sides of the sliding sleeve 25, providing a mounting base for the threaded rod 27. The positioning rods 26 ensure the stability and accuracy of the installation of the threaded rod 27.

[0058] The threaded rod 27 is fixedly mounted on the positioning rod 26, and can extend into the positioning grooves 28 on both sides of the filter box 3, and is connected with the threads at the bottom of the positioning grooves 28. This design allows the threaded rod 27 to be tightly matched with the threads in the positioning grooves 28 by rotating it, thereby achieving a stable locking of the filter box 3.

[0059] The positioning grooves 28 are provided on both sides of the filter box 3, and the bottoms thereof are provided with threads for cooperating with the threaded rods 27. The design of the positioning grooves 28 enables the threaded rods 27 to be accurately aligned and screwed in, thereby realizing the locking function.

[0060] The tight fit between the threaded rod 27 and the thread in the positioning groove 28 realizes the stable locking of the sliding sleeve 25. This design greatly improves the stability and reliability of the locking mechanism, ensuring that the sliding sleeve 25 will not shake or deflect during the filtering process.

[0061] Simply slide the sleeve 25 to a suitable position, the top positioning rod 26 will fall into the positioning groove 28 under the action of gravity, and then rotate the positioning rod 26 to screw the threaded rod 27 into the thread in the positioning groove 28 to achieve locking. This operation method is simple and fast, and greatly improves work efficiency.

[0062] The design of the positioning groove 28 and the threaded rod 27 allows the sliding sleeve 25 to be quickly unlocked and locked when needed, which is suitable for different working scenarios and needs.

[0063] In a further preferred embodiment of the utility model, a mounting plate 29 is fixedly mounted on the filter screen 7 , and bolts 30 are threadedly mounted on both sides of the mounting plate 29 , and the threads 30 are used to mount the mounting plate 29 on the filter box 3 .

[0064] In this embodiment, the mounting plate 29 is fixedly mounted on the filter screen 7, serving as a connecting bridge between the filter screen 7 and the filter box 3. The design of the mounting plate 29 increases the stability of the installation of the filter screen 7, so that the filter screen 7 can be stably inserted into the filter cavity 4, which is convenient for filtering the solid particles contained in the initial natural gas.

[0065] Both sides of the mounting plate 29 are equipped with bolts 30, which are threadedly connected to firmly mount the mounting plate 29 on the filter box 3. This connection mode is both stable and easy to operate, and is convenient for replacing or maintaining the filter screen 7 as needed.

[0066] The combination of the bolts 30 and the mounting plate 29 makes the installation and removal process of the filter screen 7 simple and quick, which not only improves the work efficiency but also reduces the maintenance cost.

[0067] The design of the mounting plate 29 increases the contact area between the filter screen 7 and the filter box 3, and cooperates with the tightening effect of the bolts 30 to effectively improve the sealing of the filter screen 7 after installation, thereby preventing gas leakage.

[0068] This design makes it easy to install and disassemble the filter 7, and the filter 7 can be cleaned and replaced more conveniently, thereby extending the service life of the filter 7 and reducing operating costs.

[0069] In summary, compared with the relevant technologies, the present device has achieved multiple optimization effects through innovative design and sophisticated mechanical structure. First, by adding a fixed plate 17 and a support frame 21, the device can flexibly adapt to different usage requirements while ensuring stability and accuracy during the filtering process. Secondly, the design of the automatic locking and unlocking function makes the switching of the filter chamber 4 simple and efficient, greatly improving work efficiency and operational convenience. Finally, the improvement of the installation structure of the filter screen 7 not only improves the sealing and stability of the filter screen 7, but also facilitates the rapid replacement and maintenance of the filter screen 7. On the whole, the present device significantly improves the efficiency, safety and ease of use of the natural gas raw gas processing process, and brings an efficient, stable and flexible solution to natural gas chemical production.
