Abstract
Description
Technical Field
[0001] This utility model relates to the field of oxygen generation equipment technology, specifically to an oxygen generation device with a self-cleaning function. Background Technology
[0002] In the field of oxygen production technology, traditional oxygen production equipment often falls short in the air filtration stage. Most of them only use simple single-layer filters or coarse filters, which have limited filtering effect on complex dust, particulate matter and other impurities in the air.
[0003] Traditional oxygen generators lack an effective self-cleaning mechanism. As the equipment runs longer, dirt accumulates on the filter components, and the filtration effect gradually decreases. This requires frequent manual shutdowns for cleaning or replacement of the filter components, which not only consumes a lot of manpower, material resources and time, but also leads to equipment downtime. Utility Model Content
[0004] The purpose of this invention is to address the problem that traditional oxygen generators in the field of oxygen generation technology have weak air filtration and lack an effective self-cleaning mechanism, resulting in decreased filtration efficiency due to the accumulation of dirt on the filter components over time. This invention provides an oxygen generator with a self-cleaning function.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0006] An oxygen generator with self-cleaning function includes a housing. An air inlet is located at the top of the housing. A filter assembly is installed inside and through the bottom of the air inlet. A compressor is located at the bottom of the filter assembly. A cooling mechanism is located at the rear of the compressor. The bottom of the cooling mechanism extends to the outer bottom of the housing. An oxygen-generating molecular sieve is located at the rear of the cooling mechanism. An adsorption tower is located at the rear of the oxygen-generating molecular sieve. Valves are installed at all pipes inside the oxygen generator. A water spraying mechanism is located at the top of the air inlet. The water spraying mechanism includes an annular pipe and a nozzle. The top of the nozzle is fixedly connected to the bottom side of the annular pipe. A circulation mechanism is fixedly connected to the side wall of the water spraying mechanism.
[0007] Furthermore, the inner side of the top of the filter assembly is slidably connected to the inner bottom of the air inlet. The filter assembly includes a sliding member, a dustproof net, and a filter box. The inner side of the bottom end of the sliding member is fixedly connected to the outer edge of the dustproof net. The filter box is located at the bottom of the dustproof net. The dustproof net can initially block large particles of dust and other impurities in the air, and then the air enters the filter box for further filtration.
[0008] Furthermore, the cooling mechanism includes a gas pipe, a loop sleeve, a water pump, a water supply pipe, and inlet / outlet water pipes. The left end of the gas pipe is connected to the rear end of the compressor, and the right end of the gas pipe is connected to the initial end of the oxygen-generating molecular sieve. The side wall of the gas pipe penetrates the entire interior of the housing. The valve is located on the side wall of the gas pipe at each stage. The coolant in the loop sleeve circulates through the water supply pipe and inlet / outlet water pipes under the action of the water pump.
[0009] Furthermore, the inner ring sidewall of the loop sleeve is fitted onto the outer sidewall of the gas pipeline. The water pipe is provided with two sets, which are respectively fixedly connected to the two ends of the loop sleeve. The first water pump is fixedly installed at the bottom end of the water pipe, and the top end of the inlet and outlet water pipes is fixedly connected to the bottom end of the first water pump. The water pipe and the inlet and outlet water pipes form a circulation, continuously removing the heat of the air in the gas pipeline.
[0010] Furthermore, the annular pipe and the nozzle are located directly above the filter assembly, and water is transported to the annular pipe via the spray pipe, and then sprayed onto the filter assembly by the nozzle.
[0011] Furthermore, the circulation mechanism includes a water tank, a second water pump, and a spray pipe. The water tank is located on the outside of the housing, and the top end of the spray pipe is fixedly connected to the top side of the spray mechanism. Under the action of the second water pump, the water in the water tank is transported to the annular pipe through the spray pipe.
[0012] Furthermore, the output end of the second water pump is fixedly connected to the bottom end of the spray pipe, the second water pump is located inside the water tank, and the side wall of the spray pipe penetrates the top side wall of the water tank.
[0013] Furthermore, an oxygen buffer tank is provided at the rear of the adsorption tower, and an oxygen collector is provided at the rear of the oxygen buffer tank. The oxygen collector is located at the right end of the outer side of the shell. A controller is provided at the front of the shell, and an installation frame is fixedly connected to the bottom of the shell. After oxygen generation and purification, the oxygen enters the oxygen buffer tank for buffering and pressure stabilization, and then enters the oxygen collector to be collected.
[0014] Compared with the prior art, this utility model provides an oxygen generator with a self-cleaning function, which has the following beneficial effects:
[0015] This self-cleaning oxygen generator effectively filters the air entering the device through a filter assembly at its air inlet, intercepting dust and other impurities to ensure air quality in subsequent oxygen production stages. This helps extend the service life of core components and improves oxygen purity. The water spray mechanism at the top of the air inlet, along with its connected circulation system, automatically cleans the filter assembly periodically, flushing away accumulated dirt and preventing a decline in filtration efficiency due to excessive impurities. This ensures consistently stable air quality, reduces the frequency of manual cleaning, improves overall equipment operating efficiency, and lowers maintenance costs. Attached Figure Description

[0027] like Figure 1 , Figure 2 and Figure 5As shown, the cooling mechanism 5 includes a gas pipe 501, a loop sleeve 502, a water pump 503, a water pipe 504, and inlet / outlet water pipes 505. The left end of the gas pipe 501 is connected to the rear end of the compressor 4, and the right end of the gas pipe 501 is connected to the initial end of the oxygen-generating molecular sieve 6. The side wall of the gas pipe 501 penetrates the entire interior of the housing 1. Valves 8 are located on the side wall of the gas pipe 501 at each stage. The inner ring side wall of the loop sleeve 502 is fitted onto the outer side wall of the gas pipe 501. Water is supplied through the pipe. Pipe 504 is provided with two sets of pipes, which are respectively fixedly connected to the two ends of the loop sleeve 502. Water pump 503 is fixedly installed at the bottom end of water pipe 504. The top end of water inlet and outlet pipe 505 is fixedly connected to the bottom end of water pump 503. The high temperature air in gas pipe 501 is cooled by exchanging heat with loop sleeve 502. The coolant in loop sleeve 502 is circulated through water pipe 504 and water inlet and outlet pipe 505 under the action of water pump 503, continuously carrying away the heat of the air in gas pipe 501. Example 2:
[0028] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the water spraying mechanism 9 includes an annular pipe 901 and a nozzle 902. The top end of the nozzle 902 is fixedly connected to the bottom side of the annular pipe 901. The annular pipe 901 and the nozzle 902 are located directly above the filter assembly 3.

The bottom end of the water pipe 1303 is fixedly connected, and the second water pump 1302 is located inside the water tank 1301. The side wall of the spray pipe 1303 penetrates the top side wall of the water tank 1301. Under the action of the second water pump 1302, the water in the water tank 1301 is transported to the ring pipe 901 through the spray pipe 1303, and then sprayed by the nozzle 902 onto the filter assembly 3 to wash away the dust and dirt accumulated on the dust screen 302 and the filter box 303. The pipe at the oxygen collector 11 is replaced with a water pump, and the discharged sewage is pumped away by the connected water pump.
[0029] Working principle: such as Figures 1-6 As shown, air first enters the equipment through the air inlet 2. During the air intake process, the filter assembly 3 starts to work. The air first passes through the dustproof net 302, which can initially block large particles of dust and other impurities in the air. Then the air enters the filter box 303 for further filtration to ensure the air quality entering the subsequent components. The filter assembly 3 can be easily disassembled, cleaned or replaced through the sliding part 301.
[0030] After filtration, the air enters the compressor 4, which compresses the air to a suitable pressure to provide the necessary conditions for the subsequent oxygen production process. The compressed high-temperature air enters the cooling mechanism 5. In the cooling mechanism 5, the high-temperature air in the gas pipeline 501 is cooled by heat exchange with the return sleeve 502. The coolant in the return sleeve 502 is circulated by the water pump 503 through the water pipe 504 and the inlet and outlet water pipes 505, continuously carrying away the heat of the air in the gas pipeline 501 and cooling the air to a temperature suitable for the operation of the oxygen-producing molecular sieve 6.
[0031] The cooled air enters the oxygen-generating molecular sieve 6. Based on its special adsorption properties, the oxygen-generating molecular sieve 6 selectively adsorbs impurities such as nitrogen in the air, so that oxygen can be enriched and separated. Then the oxygen enters the adsorption tower 7 for further processing. During this process, the valve 8 precisely controls the flow direction and flow rate of the gas in the gas pipeline 501 at each stage to ensure that the oxygen generation process proceeds in an orderly manner.
[0032] During equipment operation, the water spray mechanism 9 will periodically perform self-cleaning operation on the filter assembly 3; the water in the water tank 1301 is transported to the ring pipe 901 through the water spray pipe 1303 under the action of the water pump 1302, and then sprayed onto the filter assembly 3 by the nozzle 902 to wash away the dust and dirt accumulated on the dust screen 302 and the filter box 303. The pipe at the oxygen collector 11 is replaced with a water pump, and the discharged sewage is pumped away by the connected water pump.
[0033] After oxygen generation and purification, the oxygen enters the oxygen buffer tank 10 for buffering and pressure stabilization, and then enters the oxygen collector 11 to be collected for use; the operation of the entire equipment is centrally controlled and coordinated by the controller 12, and the mounting frame 14 provides a stable support for the equipment.
