Description

Technical Field

[0001] This utility model relates to the technical field of natural gas purification devices, and in particular to a natural gas purification device with a detachable filter element. Background Technology

[0002] Natural gas is a high-quality fuel found in porous underground rock formations, including oilfield gas, gas field gas, coalbed methane, mud volcano gas, and biogas, and can also be used as a chemical feedstock. Because natural gas contains some carbon dioxide and solid impurities, it needs to be purified before use.

[0003] A search of Chinese utility model patent (publication number CN219670438U) reveals a natural gas purification device, which includes a protective mechanism, a base plate, a fixing rod, a connecting plate, an anti-slip mechanism, and other structures. The installed protective mechanism prevents the natural gas purification device from being damaged by external objects, such as splashed paint or metal fragments, thereby extending the service life of the device.

[0004] However, practical application has revealed that this technical solution still has at least the following drawbacks:

[0005] As the filter element inside the purification unit is used over time, a large amount of impurities gradually accumulate on its surface. These impurities clog the pores of the filter element. When the pores are clogged, the speed at which natural gas passes through the filter element slows down, reducing the amount of natural gas that can be filtered per unit time, thus significantly reducing the overall filtration efficiency of the purification unit. Maintenance personnel need to spend a lot of time and effort to disassemble the complex outer casing and internal structure of the unit in order to access and replace the filter element. Utility Model Content

[0006] The present invention aims to provide a natural gas purification device with a detachable filter element to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A natural gas purification device with a detachable filter element includes a housing, a side cover detachably connected to the housing, an air inlet and an air outlet respectively provided on the side cover and the housing, an installation groove and an insertion hole provided on the side cover, the insertion hole communicating with the installation groove, a spring 1 and a spring 2 connected to the inner wall of the installation groove, a top block connected to the other end of spring 1, a locking block connected to the other end of spring 2, the locking block being rotatably connected to the inner wall of the installation groove, a connecting rod slidably connected to the side cover, a pressure block and a button connected to both ends of the connecting rod respectively, an installation ring plate slidably connected to the housing, an insertion block connected to the installation ring plate, the insertion block engaging with the insertion hole, a locking groove provided on the insertion block engaging with the locking block, a filter element connected to the installation ring plate, a bracket connected to the housing, a base connected to the bracket, and a protective device connected to the housing.

[0009] Preferably, the protective device includes a telescopic rod, the fixed end of which is connected to the housing, the telescopic end of which is connected to a protective plate, and a spring three is sleeved on the outside of the telescopic rod, with the two ends of the spring three connected to the housing and the protective plate respectively.

[0010] Preferably, the mounting ring plate is connected to a sealing ring, and the sealing ring fits into the housing.

[0011] Preferably, the base is connected to an anti-slip block, which is made of rubber.

[0012] Preferably, the side cover is connected to a flange plate one, and the housing is connected to a flange plate two, and the flange plate one and the flange plate two are connected by bolts.

[0013] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0014] (1) This technical solution, by setting up an insertion hole, spring two, a locking block, and a locking groove, limits the position of the insertion block, thereby limiting the position of the mounting ring plate. This ensures that the position of the filter element does not change during natural gas purification, preventing the filter element from shaking and rubbing against the inner wall of the housing, thus avoiding damage to the fiber structure or filter medium of the filter element, extending the service life of the filter element, and reducing the frequency of filter element replacement. It ensures that the flow path of natural gas does not change when passing through the filter element, allowing natural gas to pass evenly through all parts of the filter element, ensuring continuous and efficient filtration of impurities by the filter element, thereby stably outputting purified natural gas. By setting up a connecting rod, a top block, and a button, the locking block's restriction on the insertion block can be released. By setting up spring one and a top block, after the locking block releases its restriction on the insertion block, the insertion block can be pushed out of the insertion hole, thereby allowing the filter element to be quickly removed and replaced. It also allows for quick installation of the filter element, reducing the downtime of the device and thus reducing the overall maintenance cost.

[0015] (2) By setting up telescopic rods, springs and protective plates, when metal fragments hit the protective plates, the protective plates will effectively disperse and absorb the impact energy under the action of the impact force, so as to protect the device housing from direct damage and thus extend the service life of the device.

[0016] (3) By setting a sealing ring, unpurified natural gas is prevented from passing through the gap between the mounting ring plate and the shell to the outlet, so that all natural gas must pass through the filter element to reach the outlet, ensuring that all natural gas is purified, so that natural gas can play its best role in subsequent use and improve the effective use of energy.

[0017] (4) By setting anti-slip blocks, the friction between the base and the ground is increased, preventing external forces from causing the purification device to slide, and ensuring the sealing of the pipeline connection and the accuracy of gas transmission.

[0018] (5) By setting flange one and flange two, the side cover and the shell can be tightly connected while being easy to disassemble, ensuring that natural gas flows in the device along a predetermined path, avoiding leakage into the surrounding environment, and ensuring workplace safety and the normal operation of the purification process. At the same time, maintenance personnel can relatively easily remove the side cover to replace the filter element. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0024] like Figure 1-3The natural gas purification device shown includes a detachable filter element 11, comprising a housing 2. A side cover 6 is detachably connected to the left side of the housing 2. A flange 5 is circumferentially connected to the outer wall of the side cover 6, and a second flange 4 is circumferentially connected to the outer wall of the housing 2. The flange 5 and the second flange 4 are connected by bolts. Supports 8 are connected to both the front and rear sides of the housing 2. The bottom of the two sets of supports 8 are connected to a base 9. Several sets of anti-slip blocks 10, made of rubber, are connected to the bottom wall of the base 9.

[0025] like Figure 2 As shown, the side cover 6 and the right side wall of the housing 2 are respectively provided with an air inlet 7 and an air outlet 1. Figure 3 As shown, the side cover 6 has a mounting groove 21 and a socket 17. The socket 17 has a square longitudinal section and communicates with the mounting groove 21. A spring 1 20 and a spring 22 are connected sequentially from bottom to top on the left inner wall of the mounting groove 21. A top block 19 is connected to the other end of the spring 1 20, and the bottom wall of the top block 19 fits against the bottom wall of the mounting groove 21. A locking block 23 is connected to the other end of the spring 22. The locking block 23 includes an L-shaped connecting part and a wedge-shaped protrusion. The L-shaped connecting part of the locking block 23... The corner of the connecting part is rotatably connected to the inner wall of the mounting groove 21. The side cover 6 is slidably connected to the connecting rod 25. One end of the connecting rod 25 extends into the mounting groove 21 and is connected to the pressure block 24. The other end of the connecting rod 25 located outside the mounting groove 21 is connected to the button 26. The inner wall of the housing 2 is slidably connected to the mounting ring plate 14. The left side wall of the mounting ring plate 14 is connected to the insertion block 16. The insertion block 16 cooperates with the insertion hole 17. The insertion block 16 has a slot 18, which cooperates with the slot 23. Insert 16 is inserted into mounting slot 21 through insertion hole 17. The left side wall of insert 16 presses the wedge-shaped protrusion of locking block 23 to the left and pushes it upward along its slope, causing locking block 23 to rotate. The L-shaped connecting part of locking block 23 rotates to the left, pressing spring 22 to retract. Insert 16 continues to move to the left. The bottom wall of insert 16 pushes top block 19 to the left, pressing spring 20 to retract. When the slot 18 is aligned with the wedge-shaped protrusion of locking block 23, spring 22 rebounds, pressing locking block 23, causing locking block 23 to rotate. The wedge-shaped protrusion of locking block 23 is engaged in slot 18, restricting insert 16 from moving to the right. At this point, press button 26 to the left, causing connecting rod 25 to slide to the left, which in turn moves pressure block 24 to the left. Pressure block 24 presses block 23 to the left, causing block 23 to rotate and press spring 22 again. As block 23 rotates, it gradually disengages from slot 18. When block 23 is completely disengaged from slot 18, spring 20 rebounds and pushes top block 19 to the right. Top block 19 pushes insert block 16 to the right, causing insert block 16 to move to the right. This prevents the wedge-shaped protrusion of block 23 from engaging slot 18 again. At this point, button 26 can be released. Filter element 11 is connected to the left side wall of mounting ring plate 14. Sealing ring 15 is connected around mounting ring plate 14 and fits against housing 2.

[0026] like Figure 1-2As shown, a protective device is connected to the outer wall of the shell 2. The protective device includes telescopic rods 13, of which several sets are provided. The fixed end of the telescopic rods 13 is connected to the shell 2, and the telescopic ends of the several sets of telescopic rods 13 are connected to a protective plate 3. The protective plates 3 are arranged in a circular array of four sets. Springs 12 are sleeved on the outer side of the telescopic rods 13, and the two ends of the springs 12 are connected to the shell 2 and the protective plates 3, respectively. When an object collides with the protective plate 3, the telescopic rods 13 contract, and the springs 12 undergo elastic deformation to buffer the impact energy, thereby reducing the impact energy.

[0027] The housing 2 is connected to a bracket 8, the bracket 8 is connected to a base 9, and the base 9 is connected to an anti-slip block 10, which is made of rubber.

[0028] The specific implementation process is as follows:

[0029] During installation, insert the insert block 16 into the mounting slot 21 through the insertion hole 17 until the locking block 23 is engaged in the slot 18, thereby installing the filter element 11 on the side cover 6. Insert the filter element 11 into the housing 2 until flange 5 and flange 4 are fitted together, and connect flange 5 and flange 4 together with bolts. During use, unfiltered natural gas enters the housing 2 through the inlet 7, passes through the mounting ring plate 14 and enters the filter element 11. After being purified by the filter element 11, it is discharged from the housing 2 through the outlet 1. During disassembly, rotate to remove the bolts on flange 5 and flange 4, pull the side cover 6 outward, so that the mounting ring plate 14 and the filter element 11 are moved out of the housing 2. Press the button 26 to disengage the locking block 23 from the slot 18, and push the insert block 16 outward by the top block 19. Release the button 26 and pull the mounting ring plate 14 until the insert block 16 is separated from the insertion hole 17. At this time, the filter element 11 is removed from the side cover 6.

[0030] The above descriptions are merely embodiments of this utility model. Commonly known technical solutions and / or characteristics are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
