Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a pressing type oil-free double-cylinder air compressor filtering device. Background Art

[0002] The working principle of an oil-free air compressor is generally that a motor directly drives a compressor, causing the crankshaft to rotate, driving a connecting rod to cause a piston to reciprocate, and causing a change in the cylinder volume. Due to the change in pressure inside the cylinder, air enters the cylinder through an intake valve after passing through an air filter. During the compression stroke, due to the reduction of the cylinder volume, the compressed air, through the action of an exhaust valve, enters a storage tank through an exhaust pipe and a check valve. Since an oil-free double-cylinder air compressor is generally applied to the food or medical industry, the purity requirement for the compressed air is very high. When discharging the gas into the storage tank, the gas will be purified by a filtering device before being discharged into the storage tank;

[0003] After the filtering device is used for a period of time, the filtering effect of the filter element inside the filtering device will be greatly reduced, and the filter element needs to be replaced. However, most of the existing air compressor filtering devices are of a closed and sealed structure, making it inconvenient for workers to take out and replace the filter element. Therefore, it is urgent to design a pressing type oil-free double-cylinder air compressor filtering device to solve the above problems. Summary of the Utility Model

[0022] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0023] As Figures 1-4As shown in the figure, a pressure-type oil-free double-cylinder air compressor filtering device provided by an embodiment of the present utility model includes an air compressor main body 1 and a filtering component 6. Two disassembly and assembly components 27 are arranged on one side of the filtering component 6. The disassembly and assembly component 27 includes a fixing plate 12, a sealing plate 15, a limiting plate 19 and a plug rod 22. The fixing plate 12 is arranged on one side of the filtering component 6. The sealing plate 15 is fixedly installed on one side of the limiting plate 19. The limiting plate 19 is located below the fixing plate 12. Slots 20 are opened on the upper sides of both the fixing plate 12 and the sealing plate 15. The two slots 20 correspond to each other. The plug rod 22 is slidably installed in the two slots 20. On both sides of one end of the plug rod 22, there are clamping blocks 23. On the bottom circumference of the inner wall of the slot 20 located on the limiting plate 19, two clamping grooves are opened. The two clamping blocks 23 respectively correspond to the two clamping grooves. The filtering component 6 includes a filtering box body 13 and filter elements 14. The number of the filter elements 14 is two. The two filter elements 14 are both arranged in the filtering box body 13. Two installation grooves are opened on one side of the filtering box body 13. The two sealing plates 15 are respectively inserted into the two installation grooves. The two filter elements 14 are respectively clamped on one side of the two sealing plates 15. The two fixing plates 12 are respectively fixedly installed on the upper sides of the two installation grooves. Two notches 21 are opened on the upper side of the fixing plate 12. The two notches 21 are located on both sides of the slot 20. A pulling block 17 is arranged on the upper side of the slot 20. Springs 24 are arranged between the pulling block 17 and the two notches 21. A rotating block 18 is rotatably installed on the upper side of the pulling block 17. One side of the rotating block 18 is fixedly connected to the plug rod 22. A sliding groove is opened on the upper side of the rotating block 18. The plug rod 22 is located in the sliding groove.

[0024] Specifically, in this embodiment, when the filter element 14 needs to be replaced, by rotating the rotating block 18 to drive the plug rod 22 to rotate, the rotation of the plug rod 22 drives the clamping block 23 to rotate, so that the clamping block 23 rotates out of the clamping groove. Then, pull the pulling block 17 upward to drive the rotating block 18 to move upward. The upward movement of the rotating block 18 drives the plug rod 22 and the clamping block 23 to move upward. When the plug rod 22 and the clamping block 23 are pulled out of the slot 20 located on the limiting plate 19, by pulling the limiting plate 19 outward, the limiting plate 19 drives the sealing plate 15 to disengage from the installation groove. At the same time, the sealing plate 15 will drive the filter element 14 to move. After the filter element 14 is pulled out of the filtering box body 13, by removing the filter element 14 and replacing it with a new filter element 14, then reverse the above steps to complete the installation of the new filter element 14. The filter element 14 can be installed on one side of the sealing plate 15 by means of a buckle, or by means of screws, or other installation structures can also be used.

[0025] A pressure-type oil-free double-cylinder air compressor filtering device provided by the utility model, the air compressor main body 1 includes an air storage tank 2, a crankcase 4, a driving motor 5, a first piston cylinder 25 and a second piston cylinder 26. The crankcase 4 and the driving motor 5 are both arranged on the upper side of the air storage tank 2. The first piston cylinder 25 and the second piston cylinder 26 are both arranged on the upper side of the crankcase 4. A transmission belt 11 is arranged between the driving motor 5 and the crankcase 4. A first delivery pipe 7 is arranged at the output ends of the first piston cylinder 25 and the second piston cylinder 26. One end of the first delivery pipe 7 is fixedly connected to the bottom end of one side of the filtering box body 13. A second delivery pipe 8 is arranged on one side of the filtering box body 13. One end of the second delivery pipe 8 is fixedly connected to the air storage tank 2.

[0026] In another embodiment provided by the utility model, during air storage, by starting the driving motor 5 to drive the crankshaft in the crankcase 4 to rotate, the rotation of the crankshaft will drive the connecting rod to cause the pistons in the first piston cylinder 25 and the second piston cylinder 26 to make reciprocating motions, causing changes in the volumes of the first piston cylinder 25 and the second piston cylinder 26. Due to the pressure changes in the first piston cylinder 25 and the second piston cylinder 26, air enters the first piston cylinder 25 and the second piston cylinder 26 through the intake valve. During the compression stroke, due to the reduction of the volumes of the first piston cylinder 25 and the second piston cylinder 26, the compressed air is discharged into the first delivery pipe 7 through the action of the exhaust valve, and then is transported to the filtering box body 13 through the first delivery pipe 7. After the gas is double-purified by the two filter elements 14, the gas enters the air storage tank 2 through the second delivery pipe 8, wherein the filter element 14 is an activated carbon filter element.

[0027] Working principle: The driving motor 5 drives the crankshaft in the crankcase 4 to rotate, the crankshaft drives the connecting rod to cause the pistons in the first piston cylinder 25 and the second piston cylinder 26 to make reciprocating motions, and then the first piston cylinder 25 and the second piston cylinder 26 transport the gas to the filtering box body 13. After the gas is double-purified by the two filter elements 14, the gas enters the air storage tank 2 through the second delivery pipe 8. When the filter element 14 needs to be replaced, the limit on the limit plate 19 is released by pulling the insertion rod 22, and then the filter element 14 is removed by pulling the limit plate 19. Then, the new filter element 14 is installed into the filtering box body 13 by operating the above steps in the reverse direction, so that the filter element 14 can be disassembled and installed conveniently and quickly.

[0028] Only some exemplary embodiments of the utility model are described in the above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the protection scope of the claims of the utility model.
