Description

Technical Field

[0001] The utility model relates to the technical field of oxygen generators, in particular to an impurity removal device for the air inlet of an oxygen generator. Background Technique

[0002] An oxygen generator is a kind of machine for producing oxygen, and its principle is to utilize air separation technology. First, air is compressed at high density and then the different condensation points of the components in the air are used to carry out gas-liquid separation at a certain temperature, and then rectification is carried out to separate it into oxygen and nitrogen. Generally, since it is mostly used for producing oxygen, people are used to calling it an oxygen generator.

[0003] In the process of oxygen production of the existing oxygen generator, it is necessary to extract gas from the outside world. However, the outside gas contains more moisture, and there is also dust in the air, which will affect the oxygen production effect. At present, a filter component is installed at the air inlet of the oxygen generator to filter impurities and dry the moisture. However, in actual use, during the process of cleaning the filter, it is necessary to disassemble the filter component, and then the internal filter parts and drying parts can be cleaned, so the operation is troublesome and the cleaning efficiency is affected. Therefore, we propose an impurity removal device for the air inlet of an oxygen generator. Content of the Utility Model

[0004] The purpose of the utility model is to provide an impurity removal device for the air inlet of an oxygen generator, which solves the problems put forward in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an impurity removal device for the air inlet of an oxygen generator, including a box body, the top of the box body is detachably fixed with a box cover, and the two ends of the box body are respectively fixedly communicated with an air inlet pipe and a conduit;

[0006] Through holes are opened on both side walls of the box body, a wire mesh frame is inserted into the through holes, the wire mesh frame is of a hollow structure, the inner cavity of the wire mesh frame is filled with water-absorbing resin particles, an end plug is inserted into the outer end of the wire mesh frame, and a plurality of the wire mesh frames are arranged in a staggered manner. A filter screen plate is fixedly installed on one side of the inner cavity of the box body. A movable column is arranged on one side of the filter screen plate. Limiting rods are movably penetrated through the upper and lower sides of the side wall of the movable column, and the two ends of the limiting rods are respectively fixedly connected with the two side walls of the inner cavity of the box body. A brush is fixed on the side wall of the movable column corresponding to the filter screen plate and the brush is attached to the filter screen plate. An end plate is fixed on the other side wall of the movable column. A first electromagnet is fixed on one side wall of the end plate corresponding to the wire mesh frame, and a second electromagnet is embedded in the end face of the wire mesh frame corresponding to the end plate.

[0007] By adopting the above technical solution, the gas is decelerated by the staggeringly arranged wire frames, and then the moisture in the gas is removed by the water-absorbing resin particles in the wire frames, and then the gas is filtered for dust and impurities through the filter mesh plate, so as to improve the cleanliness of the gas entering the oxygen generator, which is conducive to improving the oxygen generation effect. At the same time, when the water-absorbing resin particles need to be replaced, the wire frame is directly pulled out, and then the end plug is pulled out to export the water-absorbing resin for replacement. At the same time, when the wire frame close to the filter mesh plate is pulled, the second electromagnet adsorbs the first electromagnet to drive the movable column to move, so as to brush and clean the filter mesh plate with the brush bristles. Pull it back and forth many times to ensure the cleaning effect. Then, after the cleaning is completed, directly pull the wire frame forcefully to separate the first electromagnet and the second electromagnet, so as to take out the corresponding wire frame, so that when replacing the water-absorbing resin in the wire frame and cleaning the filter mesh plate, the whole box body does not need to be disassembled, so the operation is convenient and fast, and the operation efficiency is improved.

[0008] As a preferred embodiment of the present utility model, an exhaust fan and a filter box are fixed on one side wall of the box body. A dust suction port is opened at the bottom of the box body corresponding to one side wall of the filter mesh plate. One end of the exhaust fan is communicated with the top of the filter box through a conduit, and the bottom of the filter box is communicated with the dust suction port through a dust suction pipe.

[0009] By adopting the above technical solution, when the exhaust fan works, negative pressure is generated in the filter box, so that the dust and impurities brushed down can be sucked out through the dust suction port, so as to realize the collection of dust and impurities, and avoid the situation that dust accumulates in the box body and affects the blockage of the filter mesh plate again.

[0010] As a preferred embodiment of the present utility model, a filter mesh sheet is fixed in the inner cavity of the filter box, and the filter mesh sheet is arranged parallel to the top of the box body.

[0011] As a preferred embodiment of the present utility model, a third electromagnet is fixed on the end face of the wire frame that fits the box body, and an adapter slot is opened on the outer wall of the box body corresponding to the third electromagnet, and an iron sheet is fixed in the slot.

[0012] As a preferred embodiment of the present utility model, a filter net is fixed in the inner cavity of the air inlet pipe.

[0013] As a preferred embodiment of the present utility model, a suitable rubber pad is fixed at the bottom of the box cover, and the box cover is detachably fixed to the top of the box body through bolts.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] The technical solution of the present application is an oxygen concentrator air inlet impurity removal device, in which mesh frames are staggeredly inserted through the two side walls of the box body, and the inner cavity of the mesh frame is filled with water-absorbing resin particles to absorb moisture, so that when replacing the water-absorbing resin particles, the mesh frame can be directly pulled out to achieve disassembly, and when the mesh frame near the filter screen is pulled, the movable column can be driven to move, thereby driving the bristles to brush and clean the filter screen, so that the water-absorbing resin particles can be replaced and the filter screen can be cleaned without overall disassembly, so that the operation is convenient and fast, and the operation efficiency is improved;

[0016] The exhaust fan generates negative pressure in the filter box, so that the dust and impurities brushed off can be sucked away by the dust suction port, thereby collecting the dust and impurities, thereby preventing dust from accumulating in the box and causing clogging of the filter screen again.

[0026] See also Figures 1 - 3 The utility model provides a technical solution: an oxygen concentrator air inlet impurity removal device, comprising a box body 1, a box cover 11 is detachably fixed on the top of the box body 1, and an air inlet pipe 12 and a conduit 13 are fixedly connected at both ends of the box body 1;

[0027] Both side walls of the box body 1 are provided with through holes, and a wire mesh frame 2 is inserted into the through holes. The wire mesh frame 2 is of a hollow structure, and the inner cavity of the wire mesh frame 2 is filled with water-absorbing resin particles. The outer end of the wire mesh frame 2 is provided with a fitting end plug 21 inserted therein. A plurality of wire mesh frames 2 are arranged staggered. On one side of the inner cavity of the box body 1, a filter screen plate 16 is fixedly installed. On one side of the filter screen plate 16, there is a movable column 4. The side wall of the movable column 4 is movably penetrated up and down by a limiting rod 14. Both ends of the limiting rod 14 are fixedly connected to the two side walls of the inner cavity of the box body 1. On the side wall of the movable column 4 corresponding to the filter screen plate 16, there is a brush 41 fixed thereto and the brush 41 is attached to the filter screen plate 16. On the other side wall of the movable column 4, there is an end plate 42 fixed thereto. On one side wall of the end plate 42, a first electromagnet 43 is fixed corresponding to the wire mesh frame 2. On the end face of the wire mesh frame 2 corresponding to the end plate 42, a second electromagnet 22 is embedded;

[0028] During actual use, first connect the conduit 13 to the oxygen generator air inlet. Then the gas first enters the inner cavity of the box body 1. The staggered wire mesh frames 2 are used to slow down the gas, and then the water-absorbing resin particles in the wire mesh frames 2 are used to dehumidify the gas. Then it passes through the filter screen plate 16 to filter dust and impurities, thereby improving the cleanliness of the gas entering the oxygen generator, and further being beneficial to improving the oxygen generation effect. At the same time, when it is necessary to replace the water-absorbing resin particles, directly pull out the wire mesh frame 2, and then pull out the end plug 21 to export the water-absorbing resin for replacement. At the same time, when pulling out the wire mesh frame 2 close to the filter screen plate 16, the adsorption of the second electromagnet 22 to the first electromagnet 43 can drive the movable column 4 to move, so as to brush and clean the filter screen plate 16 with the brush 41. Pull it back and forth multiple times to ensure the cleaning effect. Then after the cleaning is completed, directly pull the wire mesh frame 2 forcefully to separate the first electromagnet 43 and the second electromagnet 22, so as to take out the corresponding wire mesh frame 2, so that when replacing the water-absorbing resin in the wire mesh frame 2 and cleaning the filter screen plate 16, it is not necessary to disassemble the box body 1 as a whole, so the operation is convenient and fast, and the operation efficiency is improved.

[0029] Furthermore, a filter screen is fixed in the inner cavity of the air inlet pipe 12. The setting of the filter screen can initially filter out larger impurities.

[0030] Even further, a third electromagnet 23 is fixed to the end face of the wire mesh frame 2 in contact with the box body 1. At the corresponding position of the third electromagnet 23 on the outer wall of the box body 1, a fitting slot is provided and an iron sheet is fixed in the slot. Thus, when inserting the wire mesh frame 2 into the box body 1, the third electromagnet 23 is inserted into the slot, and the third electromagnet 23 and the iron sheet are adsorbed, so that the wire mesh frame 2 is stable after being inserted.

[0031] It is worth introducing that a fitting rubber pad is fixed to the bottom of the box cover 11. The box cover 11 is detachably fixed to the top of the box body 1 by bolts, so that the box cover 11 is convenient to disassemble and convenient for maintenance and repair when there is damage inside.

[0032] Such asFigure 1 and 2 As shown in 2 ; a side wall of the box body 1 is fixedly provided with an exhaust fan 3 and a filter box 31. A dust suction port 15 is opened at the bottom of the box body 1 corresponding to one side wall of the filter screen plate 16. One end of the exhaust fan 3 is communicated with the top of the filter box 31 through a conduit, and the bottom of the filter box 31 is communicated with the dust suction port 15 through a dust suction pipe. When the exhaust fan 3 works, a negative pressure is generated in the filter box 31, so that the dust and impurities brushed off can be sucked through the dust suction port 15, thereby realizing the collection of dust and impurities, and avoiding the situation that dust accumulates in the box body 1 and affects the blockage of the filter screen plate 16 again.

[0033] Furthermore, a filter mesh sheet is fixedly arranged in the inner cavity of the filter box 31. The filter mesh sheet is arranged parallel to the top of the box body 1, so that the filter mesh sheet can be used to filter and collect the dust and impurities drawn into the filter box 31.

[0034] The implementation principle of the impurity removal device for the air inlet of the oxygen generator in this application is as follows: during actual use, first connect the conduit 13 to the air inlet of the oxygen generator. Then the gas first enters the inner cavity of the box body 1. The staggered mesh frames 2 are used to slow down the gas. Then the water-absorbing resin particles in the mesh frames 2 are used to dehumidify the gas. Then it passes through the filter screen plate 16 to filter dust and impurities, thereby improving the cleanliness of the gas entering the oxygen generator, and further facilitating the improvement of the oxygen generation effect. At the same time, when the water-absorbing resin particles need to be replaced, directly pull out the mesh frame 2, and then pull out the end plug 21 to export the water-absorbing resin for replacement. At the same time, when pulling the mesh frame 2 close to the filter screen plate 16, the second electromagnet 22 adsorbs the first electromagnet 43 to drive the movable column 4 to move, so that the brush hair 41 brushes and cleans the filter screen plate 16. Pull it back and forth multiple times to ensure the cleaning effect. Then after the cleaning is completed, directly pull the mesh frame 2 forcefully to separate the first electromagnet 43 and the second electromagnet 22, so as to take out the corresponding mesh frame 2, so that when replacing the water-absorbing resin in the mesh frame 2 and cleaning the filter screen plate 16, the box body 1 does not need to be disassembled as a whole, so the operation is convenient and fast, improving the operation efficiency. And when brushing the filter screen plate 16, the exhaust fan 3 works to generate a negative pressure in the filter box 31, so that the dust and impurities brushed off can be sucked through the dust suction port 15, thereby realizing the collection of dust and impurities, and avoiding the situation that dust accumulates in the box body 1 and affects the blockage of the filter screen plate 16 again.
