Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen, in particular to a device for automatically replenishing nitrogen. Background Art

[0002] Nitrogen is a molecule composed of two nitrogen atoms with the chemical formula N2. It accounts for about 78% of the atmosphere. Nitrogen is usually a colorless, tasteless and odorless gas. It is not flammable at room temperature. It plays an important role in the formation of organisms and many compounds. Nitrogen needs to be transported to a storage device for storage to ensure safe storage and transportation.

[0003] When nitrogen is transported into the storage structure, it is mainly added by staff manually controlling valves, which not only increases labor intensity, but also increases operational risks due to manual control, which may cause accidental leakage or overfilling. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for automatically replenishing nitrogen, comprising a storage tank, an anti-skid plate, a screw and a movable plate, a fixed plate welded on the side of the storage tank, a material pump installed on the top of the fixed plate, a fixed sleeve embedded and installed on the top of the storage tank, a movable plate installed inside the fixed sleeve, the movable plate is connected to the material pump through a line, springs are respectively installed on both sides of the top of the movable plate, the tops of the two springs are fixedly connected to the top of the fixed sleeve, support plates are respectively welded on both sides of the bottom of the storage tank, connecting plates are welded on opposite sides of the two support plates, screw holes are opened on the connecting plates, the screw is meshed and connected with the screw holes, a bearing is installed on the top of the anti-skid plate, and the bottom of the screw is fixedly connected to the inner ring of the bearing.

[0006] When using an automatic nitrogen replenishing device in the technical solution, after moving the storage tank to a suitable position by casters, use the handwheel to rotate the screw, the screw rotates and moves in the screw hole of the connecting plate, the screw drives the anti-slip plate to descend, so that the anti-slip plate contacts the ground, increases the friction with the ground, and the nitrogen inside the storage tank enters the fixed sleeve. When the nitrogen pressure inside the storage tank is relatively small, the two springs inside the fixed sleeve push the movable plate downward by their own elastic force, and the movable plate applies tension to the line. Under the influence of the tension, the line starts the material pump, and the suction pipe is connected to the pipeline for conveying nitrogen. The material pump absorbs nitrogen through the suction pipe, and then conveys the nitrogen to the storage tank through the discharge pipe. The storage tank stores the nitrogen. When the nitrogen pressure inside the storage tank is relatively large, the nitrogen pushes the movable plate inside the fixed sleeve upward, and the movable plate compresses the two springs. The movable plate does not apply tension to the line, the material pump is closed, and the air outlet pipe can be opened using a valve, and the nitrogen inside the storage tank is discharged from the air outlet pipe.

[0007] Preferably, a suction pipe is installed on the side of the material pump facing away from the storage tank, and a discharge pipe is installed on the side of the material pump opposite to the storage tank, and the discharge pipe extends into the storage tank. The suction pipe is connected to a pipeline for conveying nitrogen, and the material pump absorbs nitrogen through the suction pipe and then conveys the nitrogen to the storage tank through the discharge pipe.

[0008] Preferably, an air outlet pipe is embedded and installed on the side of the storage tank away from the material pump, and a valve is installed on the air outlet pipe. The nitrogen inside the storage tank is discharged from the air outlet pipe.

[0009] Preferably, a pressure gauge is embedded in the rear end of the storage tank, and the pressure gauge can display the pressure value inside the storage tank.

[0010] Preferably, a hand wheel is installed on the top of the screw rod, and the screw rod can be rotated by using the hand wheel.

[0011] Preferably, casters are installed at the front and rear ends of the bottom of the two support plates, respectively, so as to facilitate the storage tank to move to another position.

[0012] Preferably, a movable rod is installed on the top of the anti-slide plate on one side of the bearing, and a movable hole is opened on the connecting plate on one side of the screw hole, and the top of the movable rod passes through the movable hole. The movable rod limits the anti-slide plate, and when the anti-slide plate is raised or lowered, the movable rod moves in the movable hole to prevent the anti-slide plate from shaking.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model arranges a material pump, a movable plate, a spring and a circuit, and the nitrogen inside the storage tank enters the fixed sleeve. When the nitrogen pressure inside the storage tank is relatively low, the two springs inside the fixed sleeve push the movable plate downward by their own elastic force, and the movable plate applies a pulling force to the circuit. Under the influence of the pulling force, the circuit starts the material pump, and the suction pipe is connected to the pipeline for conveying nitrogen. The material pump absorbs nitrogen through the suction pipe, and then conveys the nitrogen to the storage tank through the discharge pipe. The storage tank stores the nitrogen. When the nitrogen pressure inside the storage tank is relatively high, the nitrogen pushes the movable plate inside the fixed sleeve upward, and the movable plate compresses the two springs. The movable plate does not apply a pulling force to the circuit, and the material pump is closed, and the conveying of nitrogen to the storage tank is stopped, thereby achieving the effect of automatically replenishing nitrogen inside the storage tank and reducing labor intensity.
