Abstract
The invention discloses a low-temperature storage tank and vacuum immersed pump system for preventing frosting of connecting pipelines between a storage tank and an immersed pump. The system comprises the storage tank, the immersed pump and a plurality of connecting pipelines for connecting the storage tank and the immersed pump, wherein the storage tank comprises an inner container and a shell sleeved together; a vacuum interlayer is arranged between the inner container and the shell; a vacuum layer is arranged on the inner side of the shell of an immersed pump pond; one end of each connecting pipeline penetrates through the vacuum interlayer and is communicated with the inner container of the storage tank; the other end of each connecting pipeline penetrates through the shell of the pump pond and the vacuum layer and is communicated with the pump pond; a first connecting hole is formed in the shell; a second connecting hole is formed in the shell of the immersed pump pond; a wrapping box is arranged outside the plurality of connecting pipelines; two third connecting holes which are respectively abutted with the first connecting hole and the second connecting hole are formed in the wrapping box; the wrapping box, the shell of the storage tank and the shell of the immersed pump pond are respectively connected with one another in a sealed manner so that the wrapping box, the vacuum interlayer of the storage tank and the vacuum layer of the immersed pump pond form a vacuum entity.
Description
Technical field
The present invention relates to a kind of low-temperature storage tank and vacuum immersed pump system.
Background technique
Low-temperature storage tank and vacuum immersed pump system comprise storage tank, immersed pump and connect both some connecting tubes.Storage tank comprises the inner bag and the shell that are set in together, between inner bag and shell, is provided with vacuum sandwich.Housing inner side, immersed pump pump pond is provided with vacuum layer.Connecting tube one end was connected with storage tank inner bag through vacuum sandwich, and the other end is connected with pump pond through pump pond housing and vacuum layer.The system that affects because low temperature can produce a large amount of frostings on connecting tube in use is used.
Summary of the invention
Technical problem to be solved by this invention is: a kind of low-temperature storage tank and the vacuum immersed pump system that can avoid connecting tube between storage tank and immersed pump to occur frost is provided.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of low-temperature storage tank and vacuum immersed pump system, comprise storage tank, immersed pump and connect both some connecting tubes.Storage tank comprises the inner bag and the shell that are set in together, between inner bag and shell, be provided with vacuum sandwich, housing inner side, immersed pump pump pond is provided with vacuum layer, connecting tube one end was connected with storage tank inner bag through vacuum sandwich, the other end is connected with pump pond through pump pond housing and vacuum layer, described shell is provided with the first connection mouth, described immersed pump pump pond housing is provided with the second connection mouth, the outside of described some connecting tubes is provided with coated casing, coated casing is provided with two the 3rd connection mouths that dock with the first connection mouth and the second connection mouth respectively, the shell of described coated casing and storage tank and immersed pump pump pond housing are tightly connected respectively and make coated casing and the vacuum sandwich of storage tank and the vacuum layer in immersed pump pump pond form a vacuum entirety.
As the preferred scheme of one, described connecting tube periphery is provided with insulation material layer.
As the preferred scheme of one, described storage tank shell is provided with the vacuum gauge for measuring vacuum sandwich degree of vacuum.
As the preferred scheme of one, described connecting tube is provided with safety valve.
The invention has the beneficial effects as follows: because the outside of connecting tube is provided with coated casing, coated casing is provided with two the 3rd connection mouths that dock with the first connection mouth and the second connection mouth respectively, described coated casing and shell and immersed pump pump pond housing are tightly connected respectively, make pump pond share a vacuum body in storage tank, thereby avoid the connecting pipeline in storage tank and pump pond to occur frost; And share a set of pumped vacuum systems with storage tank, and reduce equipment investment aborning, reduce cost of production.
Because connecting tube periphery is provided with insulation material layer, can carry out cold insulation to connecting tube, reduce the heat absorption of cryogenic liquide in pipeline.
