Detailed implementation manners

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0029] Embodiment 1

[0030] An oxygen cylinder oxygen supply system includes n oxygen cylinders 1, where n ≥ 4, and the internal pressures of the n oxygen cylinders 1 are all P, and P satisfies: 0.2 Mpa < P < 1 Mpa; an air outlet pipe is connected to one of the oxygen cylinders 1, and the air outlet pipes of the n oxygen cylinders 1 are connected in parallel and then connected to an industrial production oxygen consumption system through a connecting pipe 2 for oxygen supply.

[0031] When the internal pressure P of the oxygen cylinder 1 ≤ 1 Mpa, the amount of oxygen in the gas cylinder is small, and the oxygen supply capacity of the gas cylinder is insufficient, making it difficult to meet the demand for a large oxygen supply amount and affecting the progress of production work. The amount of oxygen in a single oxygen cylinder 1 is small, the air pressure in the cylinder is low, and the oxygen supply capacity is weak. The oxygen supply of n oxygen cylinders 1 together can greatly improve the oxygen supply capacity.

[0032] Therefore, in this application, n oxygen cylinders 1 are connected in parallel and then connected to an industrial production oxygen consumption system through a connecting pipe 2 for oxygen supply.

[0033] A flowmeter 3 is installed on the connecting pipe 2 to control the oxygen outlet flow rate through the flowmeter 3.

[0034] Industrial oxygen cylinders 1 should be placed vertically as much as possible and fixed with a protection bracket. In the prior art, the oxygen cylinders 1 are mostly placed together on a chassis and limited with iron chains, etc. The fixing method has a low cost, but this fixing method is very unstable. The oxygen cylinders 1 are likely to collide with each other, and the oxygen cylinders 1 are also likely to collide with the iron chains, which is too dangerous and poses a safety threat.

[0035] The gas cylinder protection rack 4 provided in this embodiment further includes a gas cylinder protection rack 4, which includes a support plate 41, an outer protection plate 42 vertically arranged with the support plate 41, and a partition plate 43 arranged inside the outer protection plate 42 and vertically arranged with the support plate 41; there are n - 1 partition plates 43 for partitioning n compartments inside the outer protection plate 42;

[0036] A positioning groove 44 is arranged on the support plate 41 of one compartment; a limiting ring 45 is hinged at a position opposite to the positioning groove 44 on the outer protection plate 42 of one compartment, and the limiting ring 45 is arranged at one end of the outer protection plate 42 away from the support plate 41.

[0037] During use, n oxygen cylinders 1 are carried to the corresponding n compartments, and the n oxygen cylinders 1 are inserted into the corresponding n positioning grooves 44 arranged on the support seats. The n positioning grooves 44 position the n oxygen cylinders 1 to keep the gas cylinders upright, and the limiting ring is rotated to a suitable position to sleeve the gas cylinders for further limiting and fixing, ensuring the stability of the placement of the n oxygen cylinders 1.

[0038] To ensure the limiting effect of the positioning groove 44 and the limiting ring 45 and the protection effect on the gas cylinder, the diameter of the limiting ring 45 in this embodiment is 1.1 times the diameter of the gas cylinder. The limiting ring 45 is a circular ring made of stainless steel, and a rubber layer for shock absorption and protection of the gas cylinder is coated on the circular ring, and a rubber layer is also arranged in the positioning groove 44.

[0039] In this embodiment, pressure gauges are installed on all n oxygen cylinders 1, and valves are arranged on the outlet pipes of each of the n oxygen cylinders 1, which is convenient for independently controlling each of the n oxygen cylinders 1. Since the oxygen in the oxygen cylinder 1 is not allowed to be used up completely, when the remaining pressure in a certain oxygen cylinder 1 is less than 0.2 Mpa, the valve on the corresponding outlet pipe of this oxygen cylinder 1 is closed.

[0040] In this embodiment, the preferred number of oxygen cylinders 1 is 8 rollers.

[0041] The oxygen storage tank 6 in this embodiment is a steel cylinder.

The outlet main valve 61 on the oxygen supply pipe 8 is opened to supply oxygen to the oxygen-consuming system in industrial production. Mode 2: First charge oxygen and then supply oxygen. When oxygen supply is not required, the outlet main valve 61 on the oxygen supply pipe is closed, and only the oxygen storage tank 6 is charged. When oxygen supply is needed, the oxygen storage tank 6 and the oxygen-consuming system in industrial production are connected through the oxygen supply pipe, and the outlet main valve 61 on the oxygen supply pipe 8 is opened to supply oxygen.

The limiting ring 45 is a circular ring made of stainless steel, and a rubber layer for shock absorption and protection of the gas cylinder is coated on the circular ring.
