[0001] The utility model relates to the technical field of easily disassembled gas filters, in particular to an easily disassembled gas filter device. Background Technique

[0002] During the transportation of compressed gas by a compressor, in order to prevent unqualified gas quality caused by liquid water and various other impurities contained in the gas during gas transportation, which may further lead to various faults caused thereby, a gas filter is usually provided in the gas pipeline system to separate the liquid water and various impurities contained in the gas through the gas filter, and then discharge them through a drain valve to ensure the safe operation of the equipment;

[0003] Under normal circumstances, the gas filters configured for compressors adopt a downward-rotating disassembly and assembly structure or a flange-type lower disassembly and assembly structure. In order to meet the application of the above two disassembly and assembly structures under large flow or high pressure conditions, conventional gas filters must increase the volume and wall thickness of the filter, and the gas pipeline must be disassembled and assembled to replace the filter element during disassembly and assembly, which is likely to cause the risk of gas leakage due to the disassembly and assembly of flammable and explosive gas pipelines, and the disassembly and assembly difficulty and work intensity are very large, thus bringing great difficulties to on-site maintenance and replacement of the filter element;

[0004] Therefore, it is necessary to provide an easily disassembled gas filter device to solve the above technical problems. Content of the Utility Model

[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0031] An easily disassembled and assembled gas filter device includes a fastening module 1, an outlet pipe 2, a cylinder body 3, a cylinder cover 4, an inlet pipe 5, a cylinder 6, and a filter cartridge 7;

[0032] Among them, the fastening module 1 includes a screw rod 12. The upper end of the screw rod 12 passes through and is movably connected to the upper side of the cylinder body 3. The upper end of the screw rod 12 is fixedly connected to the center of a knob 11. The screw rod 12 is threadedly connected to a square rod 16. The two ends of the square rod 16 respectively pass through symmetric square cylinders 13. The two sides of the two square cylinders 13 are respectively fixedly connected to corresponding sliding shafts 17. A corresponding pair of the sliding shafts 17 are respectively arranged in corresponding L-shaped sliding grooves 18;

[0033] A corresponding pair of the L-shaped sliding grooves 18 are respectively arranged on corresponding square plates 19. The two square plates 19 are respectively fixedly connected to the cylinder 6. A corresponding pair of the sliding shafts 17 are respectively fixedly connected to corresponding L-shaped rods 14. A corresponding pair of the L-shaped rods 14 are respectively fixedly connected to corresponding semi-circular clamping plates 15.

[0034] One side of the cylinder 6 is fixedly communicated with the outlet pipe 2. The outlet end of the outlet pipe 2 passes through and is fixedly connected to the cylinder body 3.

[0035] The upper part of one side of the cylinder body 3 is fixedly communicated with the inlet pipe 5.

[0036] The lower part of the outer wall of the cylinder body 3 is threadedly connected to the cylinder cover 4.

[0037] The filter cartridge 7 is arranged inside the cylinder body 3.

[0038] The upper edge of the filter cartridge 7 matches with the two semi-circular clamping plates 15.

[0039] Working principle: First, place the filter cartridge 7 at the cylinder 6. Turn the knob 11. The knob 11 drives the lead screw 12 to rotate. The lead screw 12 drives the square rod 16 to move upward. The square rod 16 drives the square cylinders 13 to move towards each other along the square rod 16. At the same time, the two square cylinders 13 drive the corresponding sliding shafts 17 to slide along the inclined slots of the L-shaped sliding slots 18 respectively. At the same time, a set of sliding shafts 17 drive the semi-circular clamping plates 15 to move towards each other in a square shape through the L-shaped rods 14, so that the two semi-circular clamping plates 15 are tightly attached to the outer wall of the filter cartridge 7. When the sliding shafts 17 move from the inclined slot part to the straight slot part of the L-shaped sliding slot 18, the sliding shafts 17 drive the semi-circular clamping plates 15 to move upward through the L-shaped rods 14 respectively, so that the two plate-shaped clamping plates 15 drive the filter cartridge 7 to move upward, so that the two semi-circular clamping plates 15 and the cylinder 6 fasten the filter cartridge 7. At this time, stop turning the knob 11, and then screw the cylinder body 3 and the cylinder cover 4;

[0040] Then, during the gas transportation process, the gas enters the cylinder body 3, the filter cartridge 7, and the cylinder 6 through the air inlet pipe 5 and finally is discharged through the air outlet pipe 2. The filter cartridge 7 can filter out the liquid water and various impurities contained in the gas, making the gas transportation smoother;

[0041] After the gas transportation is completed, unscrew the cylinder cover 4 to expose the filter cartridge 7. At the same time, turn the knob 11 in the reverse direction to release the fixation of the filter cartridge 7 by the two semi-circular clamping plates 15. Remove the filter cartridge 7 for cleaning. When it is necessary to replace the filter cartridge 7, directly take a new filter cartridge 7 and repeat the above steps.

[0042] Beneficial effects: Place the filter cartridge 7 at the cylinder 6. Through the fastening module 1, the two semi-circular clamping plates 15 and the cylinder 6 fasten the filter cartridge 7. During the gas transportation process, the gas enters the cylinder body 3, the filter cartridge 7, and the cylinder 6 through the air inlet pipe 5 and finally is discharged through the air outlet pipe 2. The filter cartridge 7 can filter out the liquid water and various impurities contained in the gas, making the gas transportation smoother. After the gas transportation is completed, unscrew the cylinder cover 4 to expose the filter cartridge 7. At the same time, turn the knob 11 in the reverse direction to release the fixation of the filter cartridge 7 by the two semi-circular clamping plates 15. Remove the filter cartridge 7 for cleaning.
