Description

Technical Field

[0001] The present invention belongs to the technical field of oxygen filling, and particularly relates to a rapid oxygen filling process. Background Art

[0002] Oxygen is indispensable for humans and all living organisms. For oxygen-deficient areas such as plateaus and oxygen-requiring populations such as patients, oxygen supply equipment is an essential item. Portable oxygen cylinders are ideal oxygen supply devices for hospitals, first aid stations, sanatoriums, home care, battlefield rescue, personal health care, and oxygen supplementation in various oxygen-deficient environments. However, the filling of portable oxygen cylinders is restricted by conditions such as equipment, site, cost, and technology, and still needs to be completed by professional institutions and equipment.

[0003] In the prior art, a bottling machine配套 to a vehicle-mounted molecular sieve oxygen generation system is used to fill oxygen cylinders. For example, if the oxygen production capacity of the vehicle-mounted molecular sieve oxygen generation system is 20 Nm

[0010] ,

[0009] ,

[0008] , , / h, the bottling machine used is 20 Nm 3 / h. It takes about 2.5 hours to fill 10 40L oxygen cylinders to 12.5 MPa, with a slow speed, which affects the use. [[ID=IS=17]]

[0004] Therefore, in view of the above technical problems, it is necessary to provide a rapid oxygen filling process. Summary of the Invention

[0005] The purpose of the present invention is to provide a rapid oxygen filling process to solve the problem that the existing oxygen filling speed is slow and affects the use.

[0006] To achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows:

[0007] A rapid oxygen filling process, the filling device used in this process includes: a high-pressure oxygen storage tank and a bottling machine. An air outlet pipe and an air inlet pipe are connected to the high-pressure oxygen storage tank. The bottling machine is installed on the air inlet pipe. The ends of the air outlet pipe and the air inlet pipe far from the high-pressure oxygen storage tank are connected. A number of oxygen cylinders are installed on the connected part of the air outlet pipe and the air inlet pipe. <{

[0008] Further, an oxygen storage pressure detector is installed at one end of the air outlet pipe close to the high-pressure oxygen storage tank, which is used to observe the pressure value in the high-pressure oxygen storage tank, thereby reducing the probability of safety accidents.

[0009] Further, a second electric control valve and a second one-way valve are also installed on the air outlet pipe. The second electric control valve is used to control the on and off of the air outlet pipe, which is convenient for controlling whether to supply oxygen to the oxygen cylinder. The second one-way valve is used to prevent oxygen from flowing back, reducing the risk.

[0010] Furthermore, a first one-way valve and a fourth one-way valve are respectively installed on the air inlet pipe. The first one-way valve and the fourth one-way valve are arranged in opposite directions. The first one-way valve is used to control whether the filling machine can increase the pressure of the high-pressure oxygen storage tank, and the fourth one-way valve is used to control whether the filling machine fills the oxygen cylinder.

[0011] Furthermore, a first electric control valve and a fourth electric control valve are installed between the first one-way valve and the fourth one-way valve, and the bottle filling machine is located between the first electric control valve and the fourth electric control valve, both of which are used to prevent oxygen backflow.

[0012] Furthermore, a filling pressure detector is also installed on the part of the air inlet pipe near the bottle filling machine. The filling pressure detector is located on the side near the fourth electric control valve and is used to detect the pressure value during the filling process so that the staff can know it in a timely manner.

[0013] Furthermore, the connection between the outlet pipe and the inlet pipe is also equipped with a third electric control valve, an oxygen cylinder pressure detector, and a third one-way valve. The third electric control valve is used to control whether the oxygen cylinder can be filled with oxygen, thus acting as a master control switch. The oxygen cylinder pressure detector is used to detect the pressure of the oxygen cylinder during the filling process to prevent explosions. The third one-way valve is used to prevent oxygen backflow.

[0014] Furthermore, the pressure value of the high-pressure oxygen storage tank is 10-25 MPa.

[0015] A rapid oxygen filling process further includes the following steps:

[0016] S1. First, set the pre-filling setting value of the high-pressure oxygen storage tank, and turn on the bottle filling machine and the first electric control valve to stabilize the pressure value of the high-pressure oxygen storage tank at the set value.

[0017] S2. After the high-pressure oxygen storage tank reaches the set value, shut down the bottle filling machine and the first electric control valve.

[0018] S3. Install and fix the oxygen cylinder, then open the second and third electric control valves to pre-fill the oxygen cylinder through the high-pressure oxygen storage tank.

[0019] S4. If the pressure requirement of the oxygen cylinder is met, the filling ends. If the pressure requirement of the oxygen cylinder is not met, the second electric control valve is closed and the filling machine and the fourth electric control valve are opened. The filling machine continues to fill the oxygen cylinder to meet the pressure requirement of the oxygen cylinder.

[0020] S5. After the oxygen cylinder reaches the required pressure, first close the third and fourth electric control valves, then open the first electric control valve, and use the filling machine to stabilize the pressure of the high-pressure oxygen storage tank at the set value.

[0021] S6. When the pressure in the high-pressure oxygen storage tank reaches the set value, shut down the bottle filling machine and the first electric control valve to end the filling process.

[0022] Furthermore, the bottle filling machine is also equipped with a PLC control program, which facilitates automatic switching of all functions based on preset pressure.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] This invention enables rapid oxygen filling by appropriately configuring the oxygen filling device. Pre-filling is performed before the actual oxygen filling. If the pre-filling meets the user's needs, it allows for quick and convenient use. If the pre-filling does not meet the user's needs, it can shorten the filling time during subsequent filling.

[0037] refer to Figures 1-3 As shown, the connection between the outlet pipe and the inlet pipe is also equipped with a third electric control valve 8, an oxygen cylinder pressure detector 9, and a third one-way valve 11.
