Problems solved by technology

The cryogenic storage tank is generally a double-layer sealed structure assembled from an inner tank and an outer shell. The inner tank is provided with an air inlet and outlet. After people complete the welding process of the inner tank of the storage tank, there will often be residual gas A certain amount of grinding iron powder, welding slag and other sundries will easily cause gas blockage and blockage of valves and pipelines after canning liquid gas, which will bring great danger to future work and seriously affect the storage tank. The safety of the tank also reduces the quality of the gas, and because the tank in the storage tank is fully sealed, it is not only difficult to disassemble and clean, but also causes gas leakage and increases the cost burden. expected

Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the specific embodiments of the accompanying drawings.

[0021] Figure 1 to Figure 7 It is a schematic diagram of the structure of the present invention.

[0022] The reference signs therein are: dust suction pipe 1, pipe end external thread 1a, notch 1b, dust collection net bag 2, joint 21, rhombic wire mesh 22, compressed air pipe 3, air outlet 3b, air inlet 3a, air outlet section 31, air intake section 32, fastening nut 4, corrugated hose 5.

[0023] Such as Figure 1 to Figure 7 As shown, the dust suction device for the inner tank of the low-temperature storage tank includes a dust suction pipe 1 that can pass through compressed gas and also serves as a dust-containing gas passage. The front end of the dust suction pipe 1 is connected with a dust collection net bag 2 for dust collection and filtration. One end is connected with a suction hose that doubles as a suction head. The s...

Abstract

The invention discloses a dust suction apparatus of an inner tank of low-temperature storage tank, which comprises a dust suction tube which can also be used as a dust-containing gas channel, compressed gas can be introduced into the dust suction tube; the front end of the dust suction tube is connected with a dust absorbing string bag used for absorbing dust and filtering, and the other end of the dust suction tube is connected with a dust suction hose used as a dust suction head; the dust suction tube is provided with a notch which extends in the axial direction of the dust suction tube; and the notch is provided and connected with a compressed gas tube which can be used for inputting the compressed air to enter the dust suction tube and sucking dust depending on a pressure difference formed in the front and back parts of flowing gas. The dust suction hose is a corrugated hose made of stainless steel, and can be moved by hand-hold and flexibly and conveniently put into the inner tank or various narrow spaces to suck the dust. The dust suction apparatus has the advantages of simple structure, novel design, good dust suction property, abrasion resistance, flexibility and capability of free bending, extension and contraction.

Description

technical field [0001] The invention relates to a dust collection device, in particular to a dust collection device for a low-temperature liquid storage tank, in particular to a dust suction device for an inner tank of a low-temperature storage tank. Background technique [0002] The inner tank of the low-temperature storage tank is a low-temperature liquid special storage device for storing low-temperature liquid nitrogen, liquid oxygen, liquid argon and liquid carbon dioxide. With the development of my country's industry, the demand for liquid gas is also increasing. Its development The application prospect is also very broad, so the quality requirements for the inner tank of the storage tank are also very high. The cryogenic storage tank is generally a double-layer sealed structure assembled from an inner tank and an outer shell. The inner tank is provided with an air inlet and outlet. After people complete the welding process of the inner tank of the storage tank, there w...
