Abstract
The present invention provides a kind of anti-icing blocking method of liquid level gauge liquid down tube and devices.Including outer barrel, inner cylinder, transit joint, liquid level gauge liquid down tube, copper wire winding arrangement, spiral winding structure.The forwarding method passes through copper wire winding arrangement and spiral winding structure double suction hot systems, take full advantage of the vacuum space between outer barrel and inner cylinder, allow liquid level gauge liquid lower pipeline to fully absorb thermal energy in vacuum space not reduce, the stifled problem of the ice of low temperature storage equipment liquid lower pipeline is completely solved, the market competitiveness of product is enhanced.
Description
Technical field
The present invention is applied to geothermal liquid storage equipment field, and the liquid level gauge liquid down tube suitable for low-temperature pressure container is anti-icing
Blocking method and device.
Background technology
In cryogenic liquid storage equipment field, it is to be related to personnel and property safety that the liquid level information in tank body, which obtains accuracy,
Important information, if information inaccuracy easily causes the generation of serious accident, and due to the inside and outside temperature of cryogenic liquid equipment
Poor big, liquid level gauge is frequently present of the stifled phenomenon of ice, influences the normal use of liquid level gauge, leads to that pot liquid cannot be understood in time
Situation and cause accident.
And it is retouched in the CN203405259U patents that anti-icing bridging structure is applied for my company under liquid level gauge liquid in the prior art
Based on stating in a manner of copper wire heat absorption, but in practical application, since brass wire diameter is limited, endothermic effect can not be according to inside and outside change
Change temperature difference timely adjustment, part tank body is caused still to block up phenomenon with the presence of ice；In addition there is electricity consumption described in CN201731704U patents
Magnetic and heating means reduce ice and block up phenomenon, and in harmful influence field, easily cause dangerous thing using electromagnetism and heating means
Therefore occur, it is not particularly suited for the field in this way.
Invention content
To solve the above problems, the present invention makes full use of the true heat insulation layer between cylinder inside and outside cryogenic liquid storage equipment, with
Increase the mode of the coiling length of liquid level gauge liquid down tube, arrange heat absorption pipeline, forms copper wire heat absorption and pipeline heat absorption double endotherm
Structure, make liquid lower pipeline from inner cylinder to outer entire body by adequately buffer heat absorption area, to prevent ice block up phenomenon generation.
The present invention is mainly by 1-outer barrel, 2-inner cylinders, 3-transit joints, 4-winding copper wires, under 5-liquid level gauge liquid
Pipe, 6-spiral winding structures
Inner cylinder and transit joint fixed-link, liquid level gauge liquid lower pipeline by transit joint to outer entire body and inner cylinder it
Between vacuum area；
After liquid level gauge liquid lower pipeline enters vacuum area, winding copper wire one end is wound liquid lower pipeline, forms copper wire
Winding arrangement, the winding copper wire other end are connected with outer barrel, can be transitioned into outer barrel body heat content in liquid lower pipeline to liquid down tube
Road heating blocks up phenomenon to slow down ice；
Liquid level gauge liquid lower pipeline forms spiral winding excessively to close to outer barrel edge in a manner of spiral winding structure simultaneously
Structure can increase pipeline heating surface area by spiral winding structure, while relatively close to outer barrel side vacuum layer leaking heat
Greatly, pipeline is excessively more conducive to by spiral winding structure mode and is heated slowly to room temperature, phenomenon is blocked up to avoid ice；
Copper wire winding arrangement of the present invention can be used with spiral winding structure in liquid level gauge liquid lower pipeline simultaneously
It can also be used alone, i.e., can only have spiral winding structure without copper wire winding arrangement or only copper wire winding arrangement in pipeline
Without spiral winding structure, it is preferred embodiment that two kinds of structures use simultaneously.
Copper wire winding arrangement of the present invention and spiral winding structure are essentially two kinds of pipeline heat dissipating methods, not both ends
Substantial pipeline, copper wire winding arrangement pipeline and spiral winding structure pipeline can be two sections of pipelines, can also partly overlap
It is even completely superposed, i.e., can also wind the superposition section that copper wire forms spiral winding and copper wire winding on spiral winding structure pipeline.
Spiral winding structure of the present invention can be, square spiral, triangle spiral, polygonal spiral etc. are variously-shaped
Spiral way, it is not limited to the spiral way that this patent is proposed.
The method that the present invention obtains dual anti-icing plugging line structure by copper wire winding arrangement and spiral winding structure, effectively
Solve the problems, such as that the ice of liquid level gauge liquid lower pipeline is stifled, increase data accuracy during cryogenic liquid storage equipment use and
Safety, meanwhile, the design due to spiral winding structure is found in use, and liquid level gauge liquid lower pipeline is made to form buffering
Band can effectively reduce pipeline to inner cylinder and outer barrel junction when vehicle traveling substantially vibrations and emergency braking
Instantaneous stress, make the service life addition significantly of line connection, update and maintenance cost substantially reduce.

A kind of front view of situation；
Wherein 1-outer container, 2-inner cylinders, 3-transit joints, 4-winding copper wires, 5-liquid level gauge liquid down tubes, 6-liquid
Position meter spiral winding structure
Specific implementation mode
Inner cylinder 2 and 3 fixed-link of transit joint, liquid level gauge liquid lower pipeline 5 are connected to outer entire body 1 by transit joint 3
Vacuum area between inner cylinder 2, after liquid level gauge liquid lower pipeline 5 enters vacuum area, 4 one end of winding copper are to liquid lower pipeline
It is wound, winding 4 other end of copper wire is connected with outer barrel, forms copper wire winding arrangement, while liquid level gauge liquid lower pipeline 5 is with spiral shell
6 mode of winding arrangement is revolved excessively to close to 1 marginal position of outer barrel, is formed spiral winding structure, is finally connected simultaneously with outer barrel
It stretches out outer barrel and connects corresponding liquid level gauge.
Copper wire winding arrangement of the present invention can be used with spiral winding structure in liquid level gauge liquid lower pipeline simultaneously
Can also be used alone, i.e., in pipeline only have spiral winding structure without copper wire winding arrangement or only copper wire winding arrangement and
There is no spiral winding structure, it is preferred embodiment that two kinds of structures use simultaneously.
Copper wire winding arrangement pipeline of the present invention and spiral winding structure pipeline are essentially two kinds of pipeline heat dissipating methods,
The not substantial pipeline in both ends, copper wire winding arrangement pipeline and spiral winding structure pipeline can be two sections of pipelines, can also
