Description

Technical Field

[0001] This utility model relates to the field of oil separator core technology, specifically a positioning device for preventing the filter element end cap from loosening. Background Technology

[0002] The oil separator element, or oil-gas separator filter element, installed in the oil-gas separator tank of an air compressor is a crucial component. It is typically made of a porous filter material that can intercept oil droplets with a diameter larger than its own pore size, thereby achieving effective separation of oil and gas. The material of the oil separator element is mostly a high-performance filter material, such as ultra-fine glass fiber. These materials not only have excellent filtration performance but can also withstand high operating pressure and temperature. The internal design of the oil separator element, including the shape and size of the flow channels, helps small-diameter oil droplets to coalesce into larger-diameter oil droplets under the action of inertial forces, and then be removed through the filtration process.

[0003] The existing oil separator core installed in the oil-gas separator tank of the air compressor is locked in place by a limiting hole in the oil-gas separator tank. This results in the oil separator core lacking a fixed structure, causing it to loosen and shift when subjected to vibration. Consequently, it cannot fully contact the oil-gas mixture, thus reducing the oil-gas separation effect, leading to an increase in the oil content in the compressed air and affecting the quality of the compressed air. Utility Model Content

[0004] This utility model provides a positioning device to prevent the filter element end cap from loosening. It has the advantage of effectively preventing loosening and positional displacement after the oil separator core is positioned and installed, thus solving the problem of displacement caused by vibration after the oil separator core is positioned and installed.

[0005] To effectively prevent loosening and positional displacement of the oil separator core after positioning and installation, this utility model provides the following technical solution: a positioning device for preventing loosening of the filter element end cap, comprising an oil separator core, an oil separator core cover on the oil separator core, a movable groove evenly formed inside the oil separator core cover, a ring cover movably mounted on the top surface of the oil separator core cover, a pressing power assembly mounted on the outer surface of the ring cover, a sealing ring mounted on the outer surface of the ring cover, and a pressing anti-loosening assembly evenly mounted inside the oil separator core cover, the pressing anti-loosening assembly comprising a movable block and a pressing block, the movable block being movably mounted on the inner wall of the movable groove, and the pressing block having pressing points evenly mounted on the outer surface.

[0006] As a preferred embodiment of this utility model, the compression anti-loosening component further includes two fixed columns and two pressure columns. The two fixed columns are installed on the inner wall of the moving groove, and the two pressure columns are installed on the outer surface of the moving block.

[0007] As a preferred embodiment of this utility model, both pressure columns have pressure grooves inside, and the inner wall of the pressure grooves is in contact with the outer surface of the pressure column.

[0008] As a preferred embodiment of this utility model, compression springs are installed on the inner walls of both compression grooves, and one end surface of the compression spring is fixedly connected to one end surface of the compression column.

[0009] As a preferred technical solution of this utility model, the extrusion power assembly includes several inserts and several first threaded grooves. Several inserts are installed on the bottom surface of the ring cover, and several first threaded grooves are opened inside the ring cover.

[0010] As a preferred embodiment of this utility model, the outer surface of the insert block is in movable contact with the inner wall of the movable groove, and the outer surface of the insert block is in movable contact with the outer surface of the movable block.

[0011] As a preferred technical solution of this utility model, the oil separator core cover is provided with a second threaded groove evenly distributed inside, and the inner wall of the first threaded groove and the inner wall of the second threaded groove are movably installed with threaded pins.

[0012] Compared with the prior art, this utility model provides a positioning device to prevent the filter element end cap from loosening, which has the following beneficial effects:

[0013] The positioning device for preventing the filter element end cap from loosening works by having a locking block, a movable block, a pressing block, and a pressing tip cooperate with each other. The pressing tips on the outer sides of several pressing blocks press and fix the oil-gas separator tank, thus preventing the oil separator core from loosening in the oil-gas separator tank after installation. This ensures the normal operation and high efficiency of the air compressor, thereby improving the overall performance and reliability of the air compressor and reducing the maintenance cost and replacement frequency of the equipment.

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.

[0020] Please see Figures 1-4 This utility model discloses a positioning device for preventing filter element end cap loosening, including an oil separator core 1, an oil separator core cover 2 on the oil separator core 1, a movable groove 3 evenly opened inside the oil separator core cover 2, a ring cover 4 movably installed on the top surface of the oil separator core cover 2, a pressing power component installed on the outer surface of the ring cover 4, a sealing ring 16 installed on the outer surface of the ring cover 4, and a pressing anti-loosening component evenly installed inside the oil separator core cover 2. The pressing anti-loosening component includes a movable block 6 and a pressing block 11. The movable block 6 is movably installed on the inner wall of the movable groove 3, and the outer surface of the pressing block 11 is evenly installed with pressing tips 12. The pressing anti-loosening component also includes two fixed posts 8 and two pressing posts 7. The two fixed posts 8 are installed on the inner wall of the movable groove 3, and the two pressing posts 7 are installed on the outer surface of the movable block 6. Both pressure grooves 9 are provided inside the oil-gas separator. The inner wall of the pressure groove 9 is in contact with the outer surface of the pressure column 7. Compression springs 10 are installed on the inner walls of both pressure grooves 9. One end of the compression spring 10 is fixedly connected to one end of the pressure column 7. The pressure tips 12 on the outer side of each pressure block 11 press and fix the inner wall of the oil-gas separator, so that the installed oil separator core 1 will not loosen in the oil-gas separator, ensuring the normal operation and high efficiency of the air compressor. It avoids problems such as reduced filtration efficiency and gas leakage caused by the loosening of the oil separator core 1, thereby improving the overall performance and reliability of the air compressor, reducing the damage to the oil separator core 1 caused by vibration or loosening, thus extending its service life, reducing the maintenance cost and replacement frequency of the equipment, and improving the economy and sustainability of the equipment.

[0021] The extrusion power assembly includes several insert blocks 5 and several first threaded grooves 13. The insert blocks 5 are installed on the bottom surface of the ring cover 4. The ring cover 4 has several first threaded grooves 13 inside. The outer surface of the insert blocks 5 is in contact with the inner wall of the movable groove 3 and the outer surface of the movable block 6. The oil separator core cover 2 has evenly distributed second threaded grooves 14 inside. Threaded pins 15 are movably installed on the inner walls of the first threaded grooves 13 and the inner walls of the second threaded grooves 14. First, the insert blocks 5 at the bottom of the ring cover 4 are inserted into the movable groove 3, and then several threaded pins are installed. 15 is screwed into the first threaded groove 13, and the sealing ring 16 on the outside of the ring cover 4 is in active contact with the inner wall of the oil-gas separator. The active contact between the sealing ring 16 and the inner wall of the oil-gas separator improves the sealing performance of the installation and prevents gas or liquid leakage. Then, the oil separator core 1 is inserted into the groove inside the oil-gas separator. The screw is turned with a screwdriver, and the screw is screwed from the first threaded groove 13 into the second threaded groove 14. At the same time, the screw 15 presses the ring cover 4. The ring cover 4 drives several insert blocks 5 to move into the moving groove 3. The several insert blocks 5 press against the moving block 6.

[0022] The working principle and usage process of this utility model are as follows: However, it is necessary to install the oil separator core 1 into the oil-gas separator tank on the air compressor. First, insert the insert block 5 at the bottom of the ring cover 4 into the moving groove 3. Then, screw several threaded nails 15 into the first threaded groove 13. The sealing ring 16 on the outside of the ring cover 4 is in movable contact with the inner wall of the oil-gas separator tank. This movable contact between the sealing ring 16 and the inner wall of the oil-gas separator tank improves the sealing performance of the installation and prevents gas or liquid leakage. Next, insert the oil separator core 1 into the groove corresponding to the inside of the oil-gas separator tank. Tighten the threaded nails 15 with a screwdriver. The screws are screwed from the first threaded groove 13 into the second threaded groove 14. Simultaneously, the threaded nails 15 press against the ring cover 4. The ring cover 4 drives several insert blocks 5 to move towards the moving groove 3. The several insert blocks 5 press against the moving block 6, thereby causing the several moving blocks 6 to move. The movable block 6 moves within the movable groove 3, causing several movable blocks 6 to synchronously drive the pressure columns 7 at both ends to move within the pressure grooves 9 inside the fixed column 8. This causes the pressure columns 7 to compress the connecting spring, and the movable blocks 6 simultaneously drive several pressure blocks 11 to move, causing the pressure tips 12 on the outer sides of several pressure blocks 11 to compress and fix the inner wall of the oil-gas separator. This ensures that the installed oil separator core 1 will not loosen within the oil-gas separator, guaranteeing the normal operation and high efficiency of the air compressor. It also avoids problems such as decreased filtration efficiency and gas leakage caused by the loosening of the oil separator core 1, thereby improving the overall performance and reliability of the air compressor, reducing damage to the oil separator core 1 due to vibration or loosening, extending its service life, reducing equipment maintenance costs and replacement frequency, and improving the economy and sustainability of the equipment.
