Description

Technical Field

[0001] The utility model belongs to the technical field of gas tank drying equipment, and in particular relates to a gas tank residual water rapid drying equipment. Background Art

[0002] A gas cylinder is a container that stores gas inside. Various gases can be filled in the gas cylinder, such as industrial oxygen, industrial nitrogen, high-purity nitrogen, carbon dioxide and other gases. When the gas is used up, it needs to be recycled and refilled. It is found that after the gas cylinder is used up, moisture will remain inside. If it is not removed, the purity of the gas filled next time will be affected. The existing technology is to put the gas cylinder into a drying equipment, open the gas cylinder valve, and evaporate the moisture by heating. However, the heating pipes are generally evenly arranged in the drying box, and the heating of each gas cylinder is uneven, which affects the drying efficiency. Utility Model Content

[0005] Preferably, the air inlet end of the gas tank is movably connected with a connector, one end of the connector is connected to one end of a hose, and the other end of the hose is connected to a pipe with an air extraction port of a vacuum pump.

[0006] Preferably, a limiting ring is provided on the outer sleeve of the hose, a supporting rod is provided at the lower end of the limiting ring, and the supporting rod is fixed to the upper end of the drying box body.

[0007] Preferably, a heat-insulating layer is provided on the inner wall of the drying box.

[0008] Preferably, a support plate is provided at the bottom of the vacuum pump, and the support plate is fixed on the drying box.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The utility model places multiple groups of gas cylinders in a placement slot in sequence, opens the valve, and heats and dries them through electric heating tubes. The moisture inside the gas cylinders is heated and evaporated to form water vapor to escape, thereby removing the moisture. By arranging the heating tubes into a disc shape in the vertical direction, each part of each gas cylinder is heated evenly, thereby accelerating the evaporation of moisture inside the gas cylinders, drying quickly, and improving the drying efficiency.

[0011] 2. The utility model uses a vacuum pump to evacuate the gas tank, so that the vacuum pump draws out the water vapor, speeds up the water vapor removal efficiency, improves the removal speed, and is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
