Description

Technical Field

[0001] This utility model relates to the technical field of pressure swing adsorption (PSA) nitrogen generator body, specifically a combined PSA nitrogen generator. Background Technology

[0002] The pressure swing adsorption (PSA) nitrogen generator uses high-quality carbon molecular sieve as the adsorbent. Under certain mechanical effects, the diffusion rate of oxygen in the micropores of the carbon molecular sieve is much greater than that of nitrogen. Before the adsorption reaches equilibrium, nitrogen is enriched in the gas phase to form finished nitrogen gas.

[0003] A combined pressure swing adsorption (PSA) nitrogen generator (application number: 202122049481.3) has the advantages of filtering and purifying air and improving the purity of nitrogen produced. However, the above-mentioned problems still exist. When generating nitrogen, the PSA nitrogen generator body is often used. Air is introduced into the PSA nitrogen generator body through an external air compressor. At this time, the compressed air is prone to dust, which needs to be filtered. When using the PSA nitrogen generator body, it is not convenient to quickly connect the filter structure to the PSA nitrogen generator body, which is inconvenient for operators. Moreover, when cleaning the filter screen, it is not convenient to continue nitrogen production, which can easily affect the nitrogen production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inconvenience of quickly connecting the filter structure to the pressure swing adsorption nitrogen generator body, the inconvenience of operation for staff, the difficulty in continuously generating nitrogen when cleaning the filter screen, and the potential impact on nitrogen generation efficiency. Therefore, this invention proposes a combined pressure swing adsorption nitrogen generator.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a combined pressure swing adsorption (PSA) nitrogen generator, including a base plate. A PSA nitrogen generator body is fixedly connected to the top side of the base plate. A circular plate is fixedly connected to the inlet pipe of the PSA nitrogen generator body. A straight pipe is fitted into the inlet pipe of the PSA nitrogen generator body with clearance. A housing is fixedly connected to one side of the outer wall of the straight pipe. A mounting block is fixedly connected to the lower side of one side of the housing. The inner wall of the mounting block is threadedly connected to the inner wall of the top side of the base plate by bolts. A vertical plate is fixedly connected to the inner wall of the housing. A valve is fixedly connected to the inner walls of both the upper and lower sides of the vertical plate. A curved pipe is fixedly connected to one end of the valve. One side of the outer wall of the curved pipe is fixedly connected to the inner wall of one end of the housing. A sliding door is installed on the front end face of the housing. A connecting structure is provided on one side of the straight pipe.

[0007] Preferably, the connecting structure includes a housing, one end of which is fixedly connected to one side of the outer wall of a straight tube, a straight rod is fitted into the inner wall of the housing with a clearance fit, one end of which is fixedly connected to the outer side of one end of a circular plate, an inclined plate is fixedly connected to one side of the inner wall of the straight rod, a screw is attached to one side of the outer wall of the inclined plate, one side of the outer wall of the screw is threadedly connected to one side of the inner wall of the housing, and a short block is fitted into a groove at one end of the straight rod with a clearance fit, one end of which is fixedly connected to one end of the inner wall of the housing.

[0008] Preferably, a horizontal plate is fixedly connected to the outer side of the other end of the vertical plate, a filter screen is attached to one end of the horizontal plate, a horizontal block is attached to one side of the outer wall of the filter screen, and one end of the horizontal blocks on both sides is fixedly connected to the outer side of one end of the vertical plate and one end of the inner wall of the shell, respectively.

[0009] Preferably, a second valve is fixedly connected to the inner wall of the horizontal plate, and a second curved pipe is fixedly connected to one end of the second valve. One end of the second curved pipe is fixedly connected to one end of the inner wall of the shell.

[0010] Preferably, a curved rod is fitted with a clearance fit on one side of the inner wall of the horizontal plate and on one side of the groove of the filter screen, and a square rod is fitted with a clearance fit on one side of the inner wall of the curved rod. One end of the square rod is fixedly connected to a plate body, and one end of the plate body on the left and right sides is fixedly connected to the outer side of one end of the vertical plate and the outer side of one end of the inner wall of the shell, respectively.

[0011] Preferably, a spring is fitted into the outer wall of the square rod, and the upper and lower ends of the spring are fixedly connected to one end of the curved rod and one side of the outer wall of the plate, respectively.

[0012] The present invention proposes a combined pressure swing adsorption (PSA) nitrogen generator, which has the following advantages: through the cooperation of the PSA nitrogen generator body, shell, straight pipe, circular plate, mounting block and connecting structure, the device can be used by inserting the straight pipe into the outer wall of the inlet pipe of the PSA nitrogen generator body, rotating the bolt to fix the mounting block to the base plate, and simultaneously inserting the straight rod into the inner wall of the shell, rotating the screw, and the screw abutting against the inclined plate, thereby achieving connection and fixation. This facilitates the quick connection of the filter structure to the PSA nitrogen generator body and makes it convenient for operators to use.

[0013] Through the coordination of the housing, vertical plate, valve one, curved pipe one, horizontal plate, filter screen, horizontal block, curved pipe two, valve two, curved rod, square rod, and spring, the device allows air to circulate upwards by opening the upper valves one and two. At this time, pulling the lower curved rod upwards moves it out of the groove of the lower filter screen, allowing the lower filter screen to be disassembled. To disassemble the upper filter screen, open the lower valves one and two and close the upper valves one and two. Repeating this operation facilitates continuous nitrogen generation during filter screen cleaning, preventing any impact on nitrogen generation efficiency. Attached Figure Description

A curved rod 16 is fitted with a clearance fit on one side of the inner wall of the horizontal plate 10 and one side of the groove of the filter screen 18.

[0026] A square rod 17 is fitted with a clearance fit on one side of the inner wall of the curved rod 16. The square rod 17 limits the movement of the curved rod 16 when it is subjected to force.

[0029] Working principle:

[0030] When performing nitrogen generation:

[0031] Insert the straight pipe 13 into the outer wall of the air inlet pipe of the pressure swing adsorption nitrogen generator body 3, turn the bolt to fix the mounting block 7 to the base plate 1, and at the same time insert the straight rod 2a1 into the inner wall of the outer shell 2a4. Turn the screw 2a2, and the screw 2a2 abuts against the inclined plate 2a3, thereby achieving connection and fixation, completing the assembly. Compressed air is injected from one end of the curved pipe 6 through an external air compressor. At this time, open the upper valve 9 and valve 11 to allow air to circulate at the top. Then, pull the lower curved rod 16 upward to make the curved rod 16 move from... The groove of the lower filter screen 18 is removed, and the lower filter screen 18 is moved forward to disassemble it. When it is necessary to disassemble the upper filter screen 18, the lower valve 19 and valve 21 are opened, and the upper valve 19 and valve 21 are closed. The above operation is repeated to facilitate continuous nitrogen generation while the filter screen 18 is being disassembled. Compressed air enters the interior of the curved tube 2 12 after being filtered by the filter screen 18, and then enters the pressure swing adsorption nitrogen generator body 3 through the straight tube 13 to achieve nitrogen generation.
