Detailed Implementation

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

[0021] Example 1

[0022] Please refer to Figure 1-5 As shown, this utility model provides a gas purification device for a piston compressor, including a purification cylinder. The purification cylinder has an air inlet 2 and an air outlet 3 at both ends. The purification cylinder includes two sets of semi-circular shells 1. One set of semi-circular shells 1 has a first connecting plate 4 on both sides, and the other set of semi-circular shells 1 has a second connecting plate 5 on both sides. The two sets of first connecting plates 4 and two sets of second connecting plates 5 are connected near their ends by a locking mechanism. The inner side of each set of semi-circular shells 1 is provided with three sets of retaining seats 12. The inner side of the retaining seat 12 near the air inlet 2 is equipped with a first filter mechanism, the inner side of the central retaining seat 12 is equipped with a second filter mechanism, and the inner side of the retaining seat 12 near the air outlet is equipped with a third filter mechanism.

[0023] Specifically, the purification cylinder consists of two sets of semi-circular shells 1 connected by a first connecting plate 4, a second connecting plate 5, and a locking mechanism, which facilitates disassembly and maintenance. When compressed gas enters the purification cylinder from the inlet 2, it can pass through the first filter mechanism, the second filter mechanism, and the third filter mechanism in sequence, which can remove pollutants of different particle sizes respectively. Finally, the purified gas can be discharged from the outlet 3. The setting of the mounting bracket 12 can ensure that each filter mechanism is stably installed and easy to replace, realizing the modularity and maintainability of the purification function. Thus, through the above structure, efficient graded filtration and convenient maintenance of compressed gas can be achieved, which has the advantages of good purification effect and low maintenance cost.

[0024] The first filtration mechanism includes a first filter element 13, which is made of stainless steel wire mesh. The mesh structure of the first filter element 13 can block solid particles and large oil droplets in the compressed gas that are larger than the mesh size. When the compressed gas containing impurities passes through the first filter element 13, the impurities are trapped because they cannot pass through the mesh and are attached to the surface of the stainless steel wire mesh. This effectively separates large particulate pollutants in the gas, achieving preliminary filtration of the compressed gas and reducing the burden on subsequent finer filtration steps.

[0025] The second filtration mechanism includes a second filter element 14 and an adsorption layer 15. The second filter element 14 has a pleated structure and is made of polyester fiber. The adsorption layer 15 is filled with activated carbon particles. The pleated structure of the second filter element 14, made of polyester fiber, increases the interception efficiency by increasing the filtration area. By utilizing the tiny pores between the fibers, it can mechanically intercept small particulate impurities in the compressed gas. The activated carbon particles filled in the adsorption layer 15 can physically adsorb oil mist, organic vapor, odor molecules, etc. in the gas, firmly adhering them to the surface of the activated carbon. This can effectively remove the fine particles and harmful components remaining after primary filtration, further improving the purity of the gas.

[0026] The third filtration mechanism includes a third filter element 16 and a demister 17. The third filter element 16 is made of high-precision glass fiber, and the demister 17 has a corrugated plate structure. The third filter element 16 is made of high-precision glass fiber and utilizes the micron-level pore structure between the glass fibers to efficiently filter the tiny particulate pollutants remaining in the compressed gas through mechanisms such as inertial collision, interception, and diffusion. The filtration accuracy can reach the sub-micron level. The corrugated plate structure of the demister 17 utilizes the fact that when the gas passes through the tortuous channel, the mist droplets collide with the corrugated plate wall due to inertia, thereby adhering to the plate wall and realizing gas-liquid separation. This removes the residual mist moisture and oil mist in the gas, ensuring that the final discharged gas meets high-precision purification standards.

[0027] The locking mechanism includes a locking seat 10. Two sets of first connecting plates 4 each have a first groove 7 near both ends on one side. Two sets of second connecting plates 5 each have two sets of second grooves 8 near both ends on one side. A locking screw 9 is rotatably connected to the inner side of the first groove 7. One end of the locking screw 9 passes through the inner side of the second groove 8 and is threadedly connected to the locking seat 10. The bottom of the locking seat 10 abuts against the second connecting plate 5. A handwheel 11 is installed on the top of the locking seat 10. Rotating the handwheel 11 can drive the locking seat. When the locking seat 10 is rotated, it can move axially along the locking screw 9. When the locking seat 10 is tightened downwards, its bottom presses against the second connecting plate 5. At the same time, the locking screw 9 can pull the first connecting plate 4 and the second connecting plate 5 together through the cooperation of the first groove 7 and the second groove 8, thereby achieving the sealing and fixing of the two sets of semi-circular shells 1. When loosening, rotating the handwheel 11 in the opposite direction can raise the locking seat 10 to release the lock. Thus, through this setting, the assembly and maintenance of the purification cylinder can be quickly realized, effectively ensuring the sealing performance and structural stability of the purification device.

[0028] The top of the second groove 8 is provided with a limiting groove 6 to restrict the movement of the locking seat 10. The limiting groove 6 on the top of the second groove 8 can effectively limit the movement trajectory of the locking seat 10 during the locking and unlocking process, prevent it from deviating, ensure the stable transmission of axial tension of the locking screw 9, and improve the reliability of the locking mechanism connection.

[0029] Among them, a sealing gasket is provided between the two sets of semi-circular shells 1. The sealing gasket between the two sets of semi-circular shells 1 can effectively fill the gaps between the shells, enhance the sealing of the purification cylinder, prevent compressed gas leakage, ensure the normal operation of the gas purification process, and improve the overall performance of the purification device.

[0030] Working principle: First, compressed gas enters through the air inlet 2 of the purification cylinder. It first passes through the first filter element 13 made of stainless steel wire mesh, which intercepts large particulate pollutants for preliminary filtration. Then, it enters through the second filter element 14 made of pleated polyester fiber and the activated carbon adsorption layer 15, which removes fine particulate impurities and adsorbs oil mist and odors. Subsequently, it passes through the third filter element 16 made of high-precision glass fiber and the corrugated plate demister 17, which achieves fine particle filtration and gas-liquid separation. Finally, the purified gas is discharged from the air outlet 3. When disassembling and assembling the purification cylinder, it is rotated... The handwheel 11 can drive the locking seat 10 to rotate. The locking seat 10 can move axially along the locking screw 9. When the locking seat 10 is tightened downwards, its bottom presses against the second connecting plate 5. At the same time, the locking screw 9 can pull the first connecting plate 4 and the second connecting plate 5 together through the cooperation of the first groove 7 and the second groove 8, thereby achieving the sealing and fixing of the two sets of semi-circular shells 1. When loosening, rotating the handwheel 11 in the opposite direction can raise the locking seat 10 to release the lock, thereby enabling the quick assembly and maintenance of the purification cylinder and completing the entire operation process.
