Description

Technical Field

[0001] The utility model relates to the technical field of gas-containing steel cylinders, in particular to a gas-containing steel cylinder capable of detecting gas leakage. Background Art

[0002] After the gas is produced, it is mostly stored in a liquid storage tank in the form of a high-pressure, low-temperature liquid. It needs to be divided into smaller cylinders for transportation and use.

[0003] At present, the following problems exist in the packaging process: (1) Gas leakage is easy to occur during packaging. If the leakage cannot be discovered in time, on the one hand, air is easily mixed in, resulting in insufficient purity of the gas to be filled, and on the other hand, it will cause waste of gas and even danger; (2) Since the gas cylinders for collecting gas are heavy, most of the cylinders are currently placed manually in the gas storage tank, and the heights of the cylinders are inconsistent. When packaging the gas, the shorter cylinders need to be lifted up, which wastes physical strength. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a gas dispensing cylinder capable of detecting gas leakage, so as to solve the problem that gas is easily leaked during current gas dispensing and gas supply cannot be quickly stopped and warning cannot be issued after leakage.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

The screw transmission mechanism includes bearing seats connected to both sides of the base, a screw connected to the bearing seats through a rotating bearing, a guide rail connected to the base and located on both sides of the screw, and a motor transmission-connected to one end of the screw. The conversion block is threadedly connected to the screw, and the slider is slidably connected to the guide rail through the slide groove.

[0008] In the above technical solution, the motor works to drive the screw to rotate, and during the rotation of the screw, the slide seat is driven to slide along the guide rail and slide to the bottom of the cylinder body to package the gas.

[0009] Preferably, a pressure gauge is connected to the cylinder body.

[0010] Preferably, a fixing seat is welded on the top of the steel cylinder body, a gas booster pump is connected to the fixing seat via screws, and the gas booster pump is connected to the inside of the steel cylinder body via an air guide pipe.

[0011] According to the above technical solution, when the gas pressure in the cylinder body is insufficient, the gas booster pump is used to increase the pressure in the cylinder body so that the pressure in the cylinder body is in a balanced state.

[0012] Preferably, the cylinder body is connected to wire ducts on both sides of the control box, and the wires of the gas sensor pass through the wire ducts and are electrically connected to the controller.

[0014] Preferably, the scissor lift platform is connected with a plurality of fixing grooves matching the air outlet pipes.

[0015] According to the above technical solution, a gas collecting bottle for packaging gas can be placed through the fixed groove.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] (1) Place the gas collecting bottle on the scissor lift table, and transport the gas collecting bottle to the cylinder body through the screw transmission mechanism. There is no need to manually move the gas collecting bottle. When the height of the gas collecting bottle is not enough, the scissor lift table will work to drive the gas collecting bottle up so that the gas transmission pipe can be inserted into the gas inlet of the gas collecting bottle. There is no need to manually lift the gas collecting bottle, which saves time and effort and greatly improves the efficiency of packaging.

[0018] (2) When packaging the gas, insert the gas pipe into the gas inlet of the gas collecting bottle and screw the sealing sleeve so that one end of the sealing sleeve is connected to the gas inlet of the gas collecting bottle and the other end is connected to the gas pipe.

[0019] (3) The gas sensor is connected to the gas outlet pipe through a flexible rod, and the position of the gas sensor can be adjusted arbitrarily. When a gas leak occurs, the gas sensor transmits a signal to the controller. On the one hand, the controller controls the solenoid valve to close and stop dispensing gas. On the other hand, it controls the buzzer alarm to sound an alarm, thereby improving safety. BRIEF DESCRIPTION OF THE DRAWINGS
