[0002] Molecular sieve pressure swing adsorption (PSA) devices are widely used in air separation for nitrogen production, hydrogen purification, and gas drying. Their energy-saving and consumption-reducing performance has always been a core direction for technological improvement in this field.

[0003] In actual operation, impurities such as particulate matter and oil mist contained in the raw gas can easily cause the pre-filter mechanism of the unit to become clogged quickly, increasing the system pressure drop and causing additional energy consumption, which seriously restricts the continuous and stable operation and economy of the unit. In addition, the conventional filter screen disassembly and assembly process is cumbersome, which further extends the maintenance time. Utility Model Content

[0004] The purpose of this invention is to solve the problems of easy clogging of the pre-filter mechanism and inconvenient filter screen disassembly in the existing molecular sieve pressure swing adsorption device, and to propose an energy-saving and consumption-reducing molecular sieve pressure swing adsorption device.

The filtration mechanism includes a housing, which is fixedly installed on a base. The air intake pipe of the air compressor is connected to the housing. The top of the housing has an installation groove, into which a frame is inserted. The inner wall of the frame is provided with a filter screen. The striking mechanism includes a mounting base, which is fixedly mounted on a base. A motor is fixedly mounted on the mounting base, and a mounting plate is fixed to the end of the motor's shaft. A housing is fixed to the mounting plate, and a limit block is slidably provided on the inner wall of the housing.

[0009] Preferably, the box body is cylindrical, the box body is horizontally arranged, and a second spring is fixed to the inner wall of the box body, with one end of the second spring being fixedly connected to the limiting block.

[0010] Preferably, the limiting block is in the shape of a circular plate, the mounting column is in the shape of a cylindrical rod, and the mounting column is horizontally positioned.

[0011] Preferably, a support plate is fixedly installed on the back of the housing, the ball bearings roll on the support plate, and a protrusion is fixedly installed on the support plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Reference Figures 1-7 An energy-saving and consumption-reducing molecular sieve pressure swing adsorption device includes a base 1, on which a striking mechanism, a filtering mechanism, an air compressor 5 and an adsorption assembly 6 are provided. The air outlet pipe of the air compressor 5 is connected to the adsorption tank in the adsorption assembly 6. The filtration mechanism includes a housing 21, which is fixedly installed on the base 1. The air intake pipe of the air compressor 5 is connected to the housing 21. The top of the housing 21 is provided with a mounting groove 22, and a frame 26 is inserted into the mounting groove 22. A filter screen 27 is provided on the inner wall of the frame 26.

[0018] Furthermore, a conduit 4 is provided on the side of the housing 21, and a first spring 24 is fixedly installed on the housing 21.

[0019] Furthermore, a pin 25 is fixedly installed at one end of the first spring 24, and one end of the pin 25 penetrates the inner wall of the housing 21.

[0020] Furthermore, a slot 28 is provided on the frame 26. The slot 28 is cylindrical in shape, and a handle 23 is fixed to the top of the frame 26. The handle 23 is arched in shape.

[0021] It should be noted that when the molecular sieve pressure swing adsorption device is working, the air compressor 5 is turned on. The air compressor 5 draws air from the outside through the air inlet pipe, the housing 21 and the conduit 4. The outside air enters the inner wall of the housing 21 through the conduit 4, and then passes through the filter screen 27 layer by layer before entering the adsorption tank in the adsorption assembly 6 through the air compressor 5 to start adsorption. After adsorption is completed, it is discharged through the exhaust pipe on the adsorption assembly 6. When it is necessary to remove the filter screen 27, the pin 25 can be pulled to pull one end of the pin 25 away from the slot 28. At this time, the fixing of the frame 26 can be released. Then, the frame 26 can be pulled out from the mounting slot 22 through the handle 23 to achieve the purpose of removing the frame 26 so that the filter screen 27 on the inner wall of the frame 26 can be cleaned and replaced.

[0022] It is worth noting that: the box 21 is square in shape, and the box 21 is designed to accommodate the opening of the mounting groove 22. The mounting groove 22 is square in shape and is designed to accommodate the insertion of the frame 26. The filter screen 27 is designed to filter gas impurities. The conduit 4 is designed to allow external gas to enter the box 21. The first spring 24 is designed to apply force to the pin 25 so that one end of the pin 25 is inserted into the slot 28. The pin 25 is designed to be inserted into the slot 28. The handle 23 is designed to remove the frame 26.

[0023] The further advantage of the above is that, during the use of the energy-saving and consumption-reducing molecular sieve pressure swing adsorption device, a filtration mechanism is set up. This mechanism adopts a multi-layer filter screen 27 structure, which can efficiently intercept particulate matter, oil mist and trace impurities in compressed air, ensuring that the cleanliness of the gas entering the adsorption tower meets the working requirements of the molecular sieve. At the same time, the filter screen 27 adopts a quick-release buckle design, so maintenance personnel can replace the filter screen 27 without tools.

[0024] Based on Example 1, Example 2: Reference Figures 1-7 The striking mechanism includes a mounting base 31, which is fixedly mounted on the base 1. A motor 32 is fixedly mounted on the mounting base 31. A mounting plate 38 is fixedly mounted on the shaft end of the motor 32. A box 35 is fixedly mounted on the mounting plate 38. A limit block 39 is slidably provided on the inner wall of the box 35. A mounting post 37 is fixedly mounted on one end of the limit block 39. One end of the mounting post 37 passes through the box 35 and is rotatably connected to a ball bearing 36.

[0025] Furthermore, the box body 35 is cylindrical in shape and is horizontally positioned. A second spring 310 is fixed to the inner wall of the box body 35, and one end of the second spring 310 is fixedly connected to the limiting block 39.

[0026] Furthermore, the limiting block 39 is in the shape of a circular plate, and the mounting post 37 is in the shape of a cylindrical rod, with the mounting post 37 set horizontally.

[0027] Furthermore, a support plate 33 is fixedly installed on the back of the housing 21, and the ball bearing 36 rolls on the support plate 33. A protrusion 34 is fixedly installed on the support plate 33.

[0028] It should be noted that during the gas adsorption filtration process, when the motor 32 is started, the motor 32 drives the mounting plate 38 to rotate. When the mounting plate 38 rotates, it drives the ball bearing 36 to move in a circular motion through the box 35, the limiting block 39, and the mounting column 37. Due to the setting of the second spring 310, the ball bearing 36 is tightly attached to the receiving plate 33. When the ball bearing 36 moves to the protrusion 34, it will be pulled away from the receiving plate 33 by the protrusion 34. Until the ball bearing 36 leaves the protrusion 34, under the action of the second spring 310, the ball bearing 36 will be tightly attached to the receiving plate 33 again, thereby realizing the knocking effect on the receiving plate 33 and the box 21, thereby generating a vibration force and preventing the filter screen 27 from becoming clogged.

[0029] It is worth noting that: the mounting base 31 is used to support the installation of the motor 32, the model of which is HF-KP. The motor 32 is used to drive the mounting plate 38 to rotate. The mounting plate 38 is used to support the installation of the box body 35. The limiting block 39 is used to limit the movement of the mounting post 37. The mounting post 37 is used to support the rolling installation of the ball 36. The ball 36 is used to roll on the receiving plate 33. The second spring 310 is used to apply force to the ball 36 so that the ball 36 is in close contact with the receiving plate 33. The receiving plate 33 is used to support the installation of the protrusion 34. The protrusion 34 is used to drive the ball 36 away from the receiving plate 33 when the ball 36 is in circumferential motion.

[0030] A further advantage of the above is that by providing a tapping mechanism, which acts on the filter screen 27 with high-frequency tapping, directional vibration waves are periodically generated during the continuous gas filtration process to peel off micron-sized particles and oily condensates attached to the surface of the filter screen 27, which can effectively prevent the problem of increased pressure difference caused by dust accumulation.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
