Description

Technical Field

[0001] The utility model relates to the field of liquid oxygen packaging, in particular to a liquid oxygen tank vaporization packaging system. Background Art

[0002] In the shipbuilding, machinery, chemical, steel and other industries, a large amount of industrial oxygen is needed for metal flame cutting. At present, the supply of industrial oxygen is that the oxygen plant transports liquid oxygen to the liquid oxygen vaporization station by tank truck, and then the liquid oxygen vaporization station vaporizes the liquid oxygen, pressurizes it into a special high-pressure oxygen cylinder, and then transports it to each user unit by a special transport vehicle for centralized storage, and then manually moves each oxygen cylinder to each operation point for use. After the oxygen in the bottle is used up, the empty bottles are collected and centralized for storage by hand, and then the empty oxygen cylinders are transported back to the liquid oxygen vaporization station by a special transport vehicle to be refilled with oxygen. When filling oxygen, workers need to transport the empty oxygen cylinders to the corresponding filling station for filling, and after the filling is completed, they need to be transported outside. The whole process not only consumes a lot of manpower, but also consumes a lot of time, resulting in low overall filling efficiency. Therefore, the existing technology has the problem that the filling process consumes a lot of manpower and is also time-consuming. Utility Model Content

DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0015] Embodiment 1. A liquid oxygen tank vaporization and subpackaging system, comprising: Figure 1-4 As shown, it includes a liquid oxygen storage tank 1, a liquid oxygen vaporizer 2, an air compressor 3 and a filling device 4; the liquid oxygen storage tank 1 is connected to the liquid oxygen vaporizer 2 through a liquid oxygen output pipeline 5, the liquid oxygen vaporizer 2 is connected to the air compressor 3 through an oxygen output pipeline 6, and the output end of the air compressor 3 is connected to the filling device 4 through a high-pressure oxygen delivery pipe 7; the filling device 4 is provided with a plurality of gas charging stations 8 distributed side by side, and a ring conveying line 9 is provided in front of each gas charging station 8, and an inlet 10 and an outlet 11 are respectively provided at both ends of the front side of the ring conveying line 9, and a group of gas tank clamps 12 are evenly distributed on the ring conveying line 9.

[0016] The gas tank clamp 12 comprises a bottom plate 121, a semicircular bottom clamp 122 and an upper clamp 123 are arranged above the bottom plate 121, and brackets 124 are arranged at both ends between the bottom clamp 122 and the upper clamp 123; the inner wall surfaces of the bottom clamp 122 and the upper clamp 123 are provided with rubber pads 125, and the rubber pads 125 are embedded with magnets 126. Through the mutual cooperation between the semicircular bottom clamp and the upper clamp and the magnets arranged on the inner wall, the clamping degree can be effectively improved to prevent overturning, movement, etc.

[0017] A temporary storage channel 13 is provided at the front side of the outlet 11 , and a push mechanism 14 is provided at the rear side of the outlet 11 ; the push mechanism 14 comprises a push cylinder 141 , and an arc-shaped push fixture 142 is provided at the output end of the push cylinder 141 .

[0018] The packaging device 4 includes a high-pressure oxygen temporary storage tank 401 connected to the high-pressure oxygen delivery pipe 7. The output end of the high-pressure oxygen temporary storage tank 401 is provided with a charging main pipe 402. The charging main pipe 402 is provided with a plurality of charging branch pipes 403 distributed side by side. The ends of the charging branch pipes 403 are provided with charging connectors 404.

[0019] The inflatable branch pipe is a soft pipe that can be rolled up.

[0020] A liquid oxygen output control valve is installed on the liquid oxygen output pipeline.

[0021] The inflation branch pipe is also equipped with a gas control valve and a pressure gauge.

[0022] A weighing sensor and a display may also be provided on the bottom plate to display the inflation weight in real time.

[0023] The circular conveyor line can use a roller conveyor. The lower part of the front and rear sides of the bottom plate is provided with guide rollers that match the inner wall of the roller conveyor, and a telescopic frame and a spring are provided between the guide rollers and the inner wall of the roller conveyor. This facilitates the bottom plate to move along the circular conveyor line.

[0024] The upper end of the bottom plate is flush with the upper end of the circular conveyor line.

[0025] The arc of the arc-shaped pushing clamp is smaller than the bottom clamp and the upper clamp of the semicircular structure, which facilitates the arc-shaped pushing clamp to pass smoothly.

[0026] The circular conveyor line is equipped with infrared sensors and lifting baffles at the import, export and inflation station.

[0027] The working process of the utility model is as follows: a worker moves the gas cylinder to be inflated from the vehicle and carries it to the entrance of the circular conveyor line. A worker is arranged at the entrance. When a gas cylinder clamp arrives at the entrance, the worker places the gas cylinder on the gas cylinder clamp (the gas cylinder clamp uses a magnet to absorb the steel gas cylinder to prevent it from moving during the movement). Then the gas cylinder clamp moves to the inflation station along the circular conveyor line. The worker installs the inflation connector into the corresponding inflation position of the gas cylinder, opens the gas supply control valve for oxygen filling, and always pays attention to the pressure gauge. After filling to the set amount, the inflation connector is removed, and the circular conveyor line starts working to transfer the next air tank to the inflation station for inflation operation; and the gas cylinders that have been filled are moved to the exit one after another, and are pushed to the temporary storage channel under the action of the pushing cylinder and the arc-shaped pushing clamp, waiting for the workers to ship them.

[0028] Embodiment 2. The difference from Embodiment 1 is that a transverse feed channel is further provided on the front side of the inlet, a recursive cylinder and a recursive plate are provided on the left end of the feed channel, a feed push cylinder corresponding to the inlet position is provided on the right side of the feed channel, and a feed push clamp is provided on the output end of the feed push cylinder.

[0029] Preferably, the feed channel includes two front and rear feed channels, the bottoms of the two feed channels are connected through a bracket, and a cylinder that reciprocates back and forth is provided at the bottom of the bracket. In the initial state, the two feed channels are filled with gas tanks to be inflated, and one of the feed channels is located between the recursive cylinder and the feed push cylinder.

[0030] The working process is: the recursive cylinder starts working, driving the gas tank at the head end to move to the position corresponding to the inlet position, and then, when the gas tank fixture reaches the inlet position, the feed push cylinder starts working, pushing the gas tank into the inlet, contacting and being adsorbed by the gas tank fixture waiting there.

[0031] By adopting the solution of this embodiment, workers only need to replenish the gas tank regularly or at a fixed time, which can effectively reduce labor; moreover, it is also conducive to achieving continuous operation and improving inflation efficiency.
