[0002] Oxygen is a single substance formed by the oxygen element, with the chemical formula O 2 , most elements can react with oxygen. Its chemical properties are particularly active at high temperatures and can directly combine with a variety of elements. At room temperature, oxygen is not very active and is not easy to react with many substances. Oxygen participates in the metabolic process in organisms, enters the blood through breathing, and is transported to various parts of the body to meet the needs of cell metabolism. Oxygen helps to improve tissue oxygenation, increase the body's tolerance to ischemia-reperfusion injury, and reduce the incidence of postoperative complications. Oxygen can enhance the plasticity and ductility of metals, reduce their melting points and boiling points, and facilitate forging, casting and other operations. Common methods for preparing oxygen include: oxygen production from potassium permanganate, oxygen production from hydrogen peroxide, and oxygen production from potassium chlorate decomposition. When manganese dioxide is used as a catalyst to promote the decomposition of hydrogen peroxide into water and oxygen, the manganese dioxide needs to be recovered after use;

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: an oxygen preparation device for recycling raw materials, comprising: a bottom plate 1, a universal wheel 2, a threaded rod 3, an anti-slip plate 4, an anti-slip pad 5, a preparation box 6, a feeding port 7, an electric telescopic rod 8, a catalyst placement plate 9, a filter hole 10, an oxygen collection box 11, a gas transmission pipe 12, a first valve 13, a one-way valve 14, a dehumidification sponge 15, a pipeline door 16 and a vacuum pump 17;

[0028] When using the oxygen preparation device which is convenient for recycling raw materials, Figure 1 and Figure 2As shown, pull the handle on the upper side of the bottom plate 1 to move the bottom plate 1 to the place where oxygen needs to be prepared through the universal wheel 2, and then rotate the threaded rod 3. The rotation of the threaded rod 3 will cause the anti-skid plate 4 to rotate and move downward. When the anti-skid pad 5 on the lower side of the anti-skid plate 4 contacts the ground, continue to rotate the threaded rod 3, and the anti-skid plate 4 will no longer rotate, but will squeeze the anti-skid pad 5 to move downward, thereby preventing the bottom plate 1 from moving.

[0029] like Figure 1 As shown, open the lid on the upper side of the feeding port 7 on the upper side of the preparation box 6, add the catalyst manganese dioxide to the upper inner side of the catalyst placement plate 9, and then add the hydrogen peroxide solution to the inside of the preparation box 6 along the inner wall of the preparation box 6. At this time, the hydrogen peroxide does not contact the catalyst on the upper side of the catalyst placement plate 9, and will slowly release oxygen, and close the lid on the upper side of the feeding port 7;

[0030] like Figure 1 As shown, in the initial state, the first valve 13 inside the gas pipe 12 is in an open state, the vacuum pump 17 is started to pump out the air in the oxygen collecting box 11, and the air in the preparation box 6 is pumped out through the gas pipe 12, so that the preparation box 6 and the oxygen collecting box 11 are in a vacuum state, the electric telescopic rod 8 is started, and the electric telescopic rod 8 will descend together with the catalyst placement plate 9, so that the catalyst manganese dioxide on the upper side of the catalyst placement plate 9 is in contact with the hydrogen peroxide solution, and the generated oxygen will be transported to the oxygen collecting box 11 through the gas pipe 12 under the action of air pressure, and a one-way valve 14 is provided on the right side of the gas pipe 12, and the one-way valve 14 can prevent the oxygen from flowing back from the oxygen collecting box 11 to the preparation box 6. When the oxygen preparation is completed, the hydrogen dioxide solution will decompose into water and oxygen, and the oxygen will be stored in the oxygen collecting box 11, and the water will be left in the preparation box 6;

[0031] like Figure 1 and Figure 4 As shown, when the oxygen is prepared, the electric telescopic rod 8 is started, and the electric telescopic rod 8 is moved upward with the catalyst placement plate 9, so that the manganese dioxide on the upper side of the catalyst placement plate 9 is separated from the water. In addition, a filter hole 10 is opened on the lower side of the inner part of the catalyst placement plate 9, and the water will flow out from the filter hole 10, so that only the manganese dioxide on the upper side of the catalyst placement plate 9 can rise, so as to facilitate recovery, and then open the cover on the upper side of the feeding port 7 and turn the valve on the left side of the drain port of the preparation box 6 to allow the water in the preparation box 6 to be discharged from the drain port;

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, a dehumidification sponge 15 is arranged in the middle of the gas pipe 12. When the oxygen is transmitted to the oxygen collecting box 11 through the gas pipe 12, the oxygen will contact the dehumidification sponge 15. The dehumidification sponge 15 can remove the moisture in the oxygen to ensure that the oxygen in the oxygen collecting box 11 is relatively dry. When the dehumidification sponge 15 needs to be replaced, the corresponding first valve 13 is closed, and then the pipeline door 16 is opened to take out the dehumidification sponge 15, and the pipeline on the left side of the one-way valve 14 is blocked. Due to the action of the first valve 13 and the one-way valve 14, the oxygen will not leak out. After replacing the dehumidification sponge 15, the pipeline door 16 is closed, and the dehumidification sponge 15 on the other side can still dry the oxygen, which will not affect the oxygen preparation process. The dehumidification sponge 15 on the other side can be treated in the same way.
