Description
Technical field
The utility model relates to low-temperature (low temperature) vessel field, is related specifically to a kind of new type low temperature container evacuator.
Background technique
Along with cryogenic technique is in the extensive use of every field, low-temperature (low temperature) vessel is also developing rapidly, vacuum insulation deep cooling pressurized container vacuumize the important step that operation also becomes container production process flow process, as shown in Figure 1, traditional pumped vacuum systems is made up of the vacuum-pumping tube 3 be communicated with successively, vacuum valve 4, vacuum pump 6 three part, low-temperature (low temperature) vessel 1 comprises interlayer 2, and vacuum-pumping tube 3 is communicated with interlayer 2, is connected between vacuum valve 4 with vacuum pump 6 with metallic hose 5.This Dynamic System is simple, but there are some defects, and pump-down time is long.Partial vacuum pipe needs to stretch into interlayer inside, need if desired to beat several inlet holes on vacuum-pumping tube, drill process is very loaded down with trivial details, and this system is in the process vacuumized, if run into accident power-off situation, to bring a series of cleaning task afterwards and repeated work, the thermal insulating material even in interlayer is scrapped because being subject to severe contamination.
Model utility content
For solving the problem, the purpose of this utility model is to provide a kind of new type low temperature container evacuator, and this apparatus structure is simple, easy to use, can effectively prevent the impurity in interlayer from entering in vacuum pump.
For achieving the above object, a kind of new type low temperature container evacuator disclosed in the utility model, it comprises the vacuum-pumping tube, vacuum valve and the vacuum pump that connect successively; Vacuum tube one end is communicated with vacuum valve, and the other end is provided with diversion division; Diversion division comprises support frame and filtrating equipment; Filtrating equipment is located on support frame, and the interlayer that described diversion division stretches into low-temperature (low temperature) vessel is inner, and the air in interlayer after filtration device enters in described vacuum-pumping tube after filtering.
Further, described filtrating equipment comprises the Stainless Steel Cloth covered on outside described support frame.
Further, described filtrating equipment also comprises the glass fiber cloth be located at outside described Stainless Steel Cloth.
Further, described diversion division is strip.
Further, described vacuum valve is connected by gas piping with vacuum pump, and gas piping is also provided with one-way valve.
Further, described vacuum valve is connected by gas piping with vacuum pump, and gas piping is also provided with filter.
Further, described vacuum valve is connected by gas piping with vacuum pump, and gas piping is also provided with cold-trap.
Further, described new type low temperature container evacuator also comprises hot nitrogen input device, described hot nitrogen input device is connected with low-temperature (low temperature) vessel by pipeline, is inputted in the cavity volume of low-temperature (low temperature) vessel by pipeline by the nitrogen after heating, and then to air heating in described interlayer.
Wherein, described gas piping is metallic hose.Vacuum valve, cold-trap and vacuum pump use flange and connection by metal hose respectively, and filter and one-way valve are welded between metallic hose; Be filled with liquid nitrogen in cold-trap, the gas of extraction cooled rapidly formation pressure reduction, substantially increases speed of finding time, extend the working life of laminated vacuum.Before vacuum pump, access one-way valve, avoid when the unexpected power-off of system, the backflow of air and lubricant oil.
Apply this novelly to vacuumize, pump-down time can reduce, working efficiency significantly improves, for jumbo low-temperature (low temperature) vessel, the operating time reduced to 5 ~ 8 days from 12 ~ 14 days of original tratitional technology, in container, pass into hot nitrogen, and then the residual gas in interlayer is heated, mezzanine space absolute pressure is increased, and gas molecule motion is accelerated, thus in interlayer, gas flows out faster.In sum, this novel evacuation system, in structure and technique, has rational in infrastructure, processes easy for installation, the advantage of energy saving.
