[0002] Liquid oxygen is a form of oxygen liquefied at low temperatures and is widely used in aerospace, medical, chemical and other fields. In some industrial processes, it may involve the step of extracting liquid oxygen from the mixture, which usually requires the use of specific separation technologies such as distillation or adsorption. Liquid oxygen usually needs to be stored in high-pressure tanks to maintain its liquid state and facilitate transportation and use.

[0003] For storage and transfer after liquid oxygen extraction, the extract is mostly in liquid form and contains a small amount of suspended solids. At present, when most storage tanks collect the mixture, the suspended solids easily clog the outlet pipe, affecting the discharge and collection of the storage tank. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a high-pressure storage tank for extracting mixtures from liquid oxygen, which solves the problem that when most current storage tanks collect mixtures, solid suspended matter easily blocks the outlet pipe, affecting the discharge and collection of the storage tank.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-pressure storage tank for extracting a mixture from liquid oxygen, comprising a tank body, a suction pipe fixedly connected to one side of the tank body, a blocking ring fixedly connected to the inner wall of the suction pipe, a discharge port formed on the blocking ring, a top end of the suction pipe fixedly connected to a protective seat, a cylinder fixedly connected within the protective seat, and a gas rod fixedly connected to the output end of the cylinder;

[0006] The bottom end of the air rod is fixedly connected to a pressure head, the position of the pressure head corresponds to the position of the discharge port, one end of the suction pipe is fixedly connected to a water pump, one end of the water pump is fixedly connected to a discharge pipe, a fixed sleeve is fixedly connected inside the discharge pipe, a lower pressure rod is slidably connected inside the fixed sleeve, one end of the lower pressure rod located at the bottom of the fixed sleeve is fixedly connected to a lower pressure roller, and the outer arc surface of the lower pressure rod located inside the discharge pipe is fixedly connected to a fixing plate.

[0007] As a further solution of the present invention: a reset spring is fixedly connected to the bottom end of the fixing plate, and the other end of the reset spring is fixed to the top end of the fixing sleeve.

[0008] As a further solution of the present invention: the bottom end of the tank body is fixedly connected to a bottom block, the bottom end of the water pump is fixedly connected to a fixing rod, and the bottom end of the fixing rod is fixedly connected to the bottom block.

[0009] As a further solution of the present invention: the bottom end of the bottom block is fixedly connected to a servo motor, and the output end of the servo motor is fixedly connected to a stirring rod.

[0010] As a further solution of the present invention: the stirring rod is arranged in the tank body, and the top end of the tank body is fixedly connected with a feed hole.

[0011] As a further solution of the present invention: the bottom end of the bottom block is fixedly connected to a movable leg, the bottom end of the movable leg is fixedly connected to a buffer rod, the number of the buffer rods is two, and the bottom end of the buffer rod is fixedly connected to a movable wheel.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The high-pressure storage tank for extracting the mixture in the liquid oxygen is provided with a cylinder, a gas rod, a discharge pipe, a lower pressure rod and a water pump. When taking the material, the cylinder can be started, and the cylinder drives the gas rod and the pressure head to rise, so that the pressure head is no longer in contact with and blocked by the discharge port. At this time, the water pump is started again, and the water pump is used to extract the mixed liquid into the discharge pipe. When discharging, the lower pressure rod can be pressed and then released, so that the lower pressure rod drives the lower pressure roller to perform piston motion in the discharge pipe. This not only makes the discharge smoother and faster, but also prevents blockage during discharge, which affects the discharge of the mixed liquid from the tank.

[0014] 2. The high-pressure storage tank for extracting the mixture in liquid oxygen is provided with moving legs, moving wheels, a servo motor and a tank body. When the high-pressure storage tank needs to be transferred, the entire high-pressure storage tank can be pushed and moved by using the moving legs and the moving wheels. The buffer rod can cushion and reduce the shock of the moving legs during the movement, thereby reducing the shaking of the mixed liquid inside the tank body. When it is normally placed, in order to prevent it from sinking to the bottom, the servo motor can be started, and the output end of the servo motor can be used to drive the stirring rod to stir the tank body, thereby preventing the mixed liquid inside the tank body from sinking to the bottom and clogging the suction pipe.

[0022] The bottom end of the bottom block 20 is fixedly connected to a servo motor 17, and the output end of the servo motor 17 is fixedly connected to a stirring rod 18. Through the arrangement of the servo motor 17 and the stirring rod 18, the servo motor 17 drives the stirring rod 18 to stir the tank body 1, thereby preventing the substances in the mixed liquid in the tank body 1 from sinking to the bottom and clogging the suction pipe 2;

[0023] A blocking ring 3 is fixedly connected to the inner wall of the suction pipe 2, and a discharge port 4 is opened on the blocking ring 3. The top of the suction pipe 2 is fixedly connected to a protective seat 5, and a cylinder 6 is fixedly connected to the protective seat 5. The output end of the cylinder 6 is fixedly connected to a gas rod 7, and the bottom end of the gas rod 7 is fixedly connected to a pressure head 8. The position of the pressure head 8 corresponds to the position of the discharge port 4. Through the setting of the pressure head 8, when the pressure head 8 is in contact with the discharge port 4, the suction pipe 2 can be sealed and blocked to prevent the mixed liquid from flowing out.

[0024] One end of the suction pipe 2 is fixedly connected to the water pump 9, the bottom end of the water pump 9 is fixedly connected to the fixed rod 10, one end of the water pump 9 is fixedly connected to the discharge pipe 11, the bottom end of the bottom block 20 is fixedly connected to the movable leg 21, the bottom end of the movable leg 21 is fixedly connected to the buffer rod 22, the number of the buffer rod 22 is two, the bottom end of the buffer rod 22 is fixedly connected to the moving wheel 23, through the arrangement of the buffer rod 22 and the moving wheel 23, when the high-pressure storage tank is transferred, it can be moved through the buffer rod 22 and the moving wheel 23, and the buffer rod 22 is used for shock absorption and buffering to prevent the tank body 1 from shaking during movement;

[0025] A fixed sleeve 12 is fixedly connected to the discharge pipe 11, and a lower pressure rod 13 is slidably connected to the fixed sleeve 12. The lower pressure rod 13 is located at one end of the bottom of the fixed sleeve 12 and is fixedly connected to a lower pressure roller 14. The outer arc surface of the lower pressure rod 13 located inside the discharge pipe 11 is fixedly connected to a fixed plate 16, and the bottom end of the fixed plate 16 is fixedly connected to a return spring 15.

When the mixed liquid needs to be extracted, the cylinder 6 is started first, and the cylinder 6 drives the gas rod 7 to rise. When the gas rod 7 rises, it drives the pressure head 8 to rise, so that the pressure head 8 is away from the discharge port 4. At this time, the water pump 9 can be started and used to extract. The mixed liquid is extracted into the discharge pipe 11 for discharge. When discharging, the lower pressure rod 13 is pressed. When released, it is reset by the internal reset spring 15. The lower pressure rod 13 drives the lower pressure roller 14 to perform piston motion in the discharge pipe 11 to discharge, thereby preventing the inside of the discharge pipe 11 from being blocked by solid sediment.
