Description

Technical Field

[0001] The utility model relates to the technical field of oxygen filtering equipment, in particular to an adsorption oxygen-generating filtering structure. Background Art

[0002] There are many ways to obtain and prepare oxygen, including physical and chemical methods. The chemical method of preparing oxygen requires the consumption of chemical raw materials, which leads to the relatively high cost of chemical oxygen production. There are two basic raw materials for oxygen production, one is water and the other is air. Oxygen production from water is through the decomposition of oxygen atoms and hydrogen atoms, and oxygen production from air is mainly through separation and filtration to remove impurities and other gases in the air. Although the cost of air adsorption oxygen production is relatively low, the efficiency of traditional structure oxygen production is relatively low. Therefore, how to solve the above-mentioned problems has become a difficult problem that needs to be solved urgently. Utility Model Content

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] (1) The utility model has a simple structure and is easy to operate and use. It can greatly increase the adsorption and filtration effect of oxygen, improve the adsorption oxygen production efficiency, and solve the technical problems of low oxygen production efficiency and high cost. The oxygen production filter tank is used to store the adsorption oxygen production fluid, air and filtered air. The air inlet elbow is connected to the pump pressure drive, or directly uses negative pressure to suck air into the oxygen production filter tank. The air outlet holes and the bubble filter baffle guide the air to flow out evenly. The bubble filter baffle can crush the bubbles. The adsorption oxygen production water pipe is responsible for introducing the adsorption oxygen production fluid, the adsorption oxygen production drainage pipe is responsible for exporting the adsorption oxygen production fluid, and the adsorption oxygen production exhaust pipe is responsible for exporting the filtered air.

[0010] (2) The air flows into the oxygen filter tank along the air inlet elbow and is evenly dispersed. The air after adsorption filtration is collected centrally. The water circulation filter is responsible for dealing with particulate impurities in the air and the oil film that may be produced on the surface of the adsorbed oxygen fluid. The annular pad and the air vents can guide the air to flow into the adsorbed oxygen fluid through the guide pipe and the air outlet holes.

[0011] (3) The solenoid valve can prevent the air or oxygen-generating adsorption fluid from overflowing. The adsorption impurity removal terminal together with the anti-detachment guide rod can float up and down with the change of liquid level. The float can prevent the adsorption impurity removal terminal from sinking into the adsorption oxygen-generating fluid. What enters the impurity introduction tank is not only a small amount of adsorption oxygen-generating fluid but also impurities and other substances in the air, which can ensure the cleanliness of the produced oxygen.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] like Figure 1-4As shown, an adsorption oxygen filtering structure comprises an oxygen filter tank 1, an air introduction elbow 2 is provided at the top of the oxygen filter tank 1, the air introduction elbow 2 extends to the inner bottom of the oxygen filter tank 1, a plurality of air outlet holes 3 are provided on the side of the bottom end of the air introduction elbow 2, a multi-layer bubble filtering baffle 4 is provided on the inner side of the oxygen filter tank 1, an adsorption oxygen water pipe 5 is provided at the top of one side of the oxygen filter tank 1, an adsorption oxygen exhaust pipe 6 is provided at the top of the other side of the oxygen filter tank 1, an adsorption oxygen drainage pipe 7 is provided at the bottom of one side of the oxygen filter tank 1, and a water circulation filter 8 is provided at the bottom of the other side of the oxygen filter tank 1. The air introduction elbow can be driven without applying kinetic energy, and only the pump pressure drive of the adsorption oxygen exhaust pipe output end is retained, or the adsorption oxygen exhaust pipe and the air introduction elbow are simultaneously driven by the pump pressure, and the air introduction elbow The multiple air outlet holes and the diversion sub-pipe on the side of the bottom can create more small bubbles and increase the adsorption and filtration effect. The air inlet elbow can also directly introduce air into the oxygen filter tank in the form of large bubbles, and cooperate with the multi-layer bubble filter baffle to decompose the large bubbles. The holes inside the multi-layer bubble filter baffle can maintain a uniform aperture, or the aperture can be gradually reduced from bottom to top. The position of the adsorption oxygen water pipe can be lower than the liquid level of the adsorption and filtration fluid, and the position of the adsorption oxygen exhaust pipe must be slightly higher than the liquid level of the adsorption and filtration fluid. A liquid level control switch can also be set inside the oxygen filter tank. When the liquid level of the adsorption and filtration fluid is about to exceed the position of the adsorption oxygen exhaust pipe, the solenoid valve is closed to stop the introduction of the adsorption and filtration fluid. The adsorption oxygen drainage pipe and the adsorption oxygen water pipe need to be kept in a balanced state.

[0021] A guide sub-tube 9 is provided on the inner side of the air outlet end of the air inlet elbow 2, and the top of the guide sub-tube 9 is set to a funnel-shaped structure. An annular pad 10 is provided on the side of the guide sub-tube 9. A plurality of air holes 11 are distributed in an array on the inner side of the annular pad 10. Part of the air flows out through the guide sub-tube, and the other part of the air flows out through the plurality of air outlet holes at the bottom end of the air inlet elbow. The funnel-shaped structure can evenly guide the air to enter the oxygen filter tank in the form of bubbles, and the plurality of air holes of the annular pad can guide the air to flow out evenly through the air outlet holes to avoid biasing to one side, which directly causes the bubbles to be too large and affects the effect of air adsorption and filtration.

[0022] The water inlet end of the adsorption oxygen production water pipe 5 and the air outlet end of the adsorption oxygen production exhaust pipe 6 are both provided with a solenoid valve 12. When there is too much oxygen production adsorption and filtering fluid, and it is about to cover the outlet of the adsorption oxygen production exhaust pipe, the solenoid valve of the adsorption oxygen production water pipe is closed, and the oxygen production adsorption and filtering fluid continues to flow in. When the oxygen storage container needs to be replaced, the solenoid valve of the adsorption oxygen production exhaust pipe is closed, or the solenoid valve of the adsorption oxygen production water pipe is closed at the same time, and then the air inlet elbow stops introducing air.

[0023] An adsorption and impurity removal terminal 13 is provided at the top of the water inlet end of the water circulation filter 8, a float 14 is provided at the top of the adsorption and impurity removal terminal 13, an impurity introduction groove 15 is provided on the side of the adsorption and impurity removal terminal 13, and an anti-detachment guide rod 16 is provided at the bottom of the adsorption and impurity removal terminal 13. The anti-detachment guide rod is a hollow conduit connected to the impurity introduction groove. The adsorption and impurity removal terminal together with the anti-detachment guide rod floats up and down with the change of liquid level, and the air particles floating on the water surface together with the oil film flow into the anti-detachment guide rod along the impurity introduction groove, and a small amount of adsorption and filtration fluid also enters the anti-detachment guide rod simultaneously.

[0024] Directions:

[0025] During operation, a certain amount of oxygen-generating adsorption filtering fluid is first introduced into the oxygen filter tank 1, and the air is introduced into the oxygen filter tank 1 along the air inlet elbow 2 through the air outlet hole 3 and the guide sub-pipe 9. The multi-layer bubble filter baffle 4 decomposes large bubbles into small bubbles, and most of other gases in the air are adsorbed by the oxygen-generating adsorption filtering fluid. Oxygen and a small part of other gases are concentrated above the oxygen-generating adsorption filtering fluid. At this time, it enters the oxygen collection tank along the adsorption oxygen exhaust pipe 6. If the collected oxygen content is low, it can be circulated into the oxygen filter tank 1 for adsorption filtration for multiple times. After a period of time, the oxygen-generating adsorption filtering fluid is in a saturated state, and the adsorption oxygen water guide pipe 5 continuously introduces the oxygen-generating adsorption filtering fluid into the oxygen filter tank 1. The saturated oxygen-generating adsorption filtering fluid is drained to the outside of the oxygen filter tank 1 through the adsorption oxygen drainage pipe 7, and the water circulation filter removes dust particles and oily substances in the oxygen-generating adsorption filtering fluid.

[0026] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
