Abstract
A kind of pearlife drying device, comprise the liquid nitrogen storage tank, heating furnace and the drying chamber that are connected successively by pipeline, be provided with gas distribution pipe in described drying chamber, the top of described drying chamber connects vavuum pump by pipeline; Described drying chamber top is also provided with drain, bottom is provided with drain hole.Compared with prior art, the utility model has the following advantages: 1, the use of liquid nitrogen storage tank, makes drying medium change nitrogen into by original air, decreases moisture content; 2, the use of heating furnace, makes the outlet temperature of heat medium reach 150 DEG C, improves heating-up temperature, ensure that heating effect; 3, the setting of gas distribution pipe in drying chamber, makes pearlife be heated heat evenly, avoids, only from the phenomenon absorbed by top pearlife after bottom heating causes humid air to rise, ensureing heating effect; 4, the use of vavuum pump, discharges in time by the moisture after heating, solves only heating and problem that moisture cannot be discharged, avoids after water vapour cools simultaneously and again absorbed by pearlife.
Description
Technical field
The utility model belongs to drying device field, specifically a kind of pearlife drying device.
Background technology
For cryogenic liquid vessel, when adopting using vacuum powder (pearlife) as adiabatic method, the moisture content of vacuum powder will affect evacuated time and vacuum life, and then has influence on manufacturing cost and result of use.National standard proposes to pearlife the requirement that moisture content is not more than 0.3% (mass ratio).The pearlife of firm output, its moisture content generally can touch the mark, but after depositing after a while or transporting, its moisture content can significantly improve, and dry pearlife is the important process link during low-temperature (low temperature) vessel manufactures before filling.
Utility model content
For the defect of prior art, the object of this invention is to provide the pearlife drying device that a kind of structure is simple, easy to operate, drying effect is good.
The technical solution of the utility model is: comprise the liquid nitrogen storage tank, heating furnace and the drying chamber that are connected successively by pipeline, be provided with gas distribution pipe in described drying chamber, the top of described drying chamber connects vavuum pump by pipeline; Described drying chamber top is also provided with drain, bottom is provided with drain hole.
Such scheme is more preferably:
Connecting line between described liquid nitrogen storage tank, heating furnace and drying chamber is metal hose, and the connecting line between described drying chamber and vavuum pump is metal bellows.
Described heating furnace is electric furnace, and described vavuum pump is water ring vacuum pump.
The outlet temperature of described heating furnace controls to be 150 DEG C.
Compared with prior art, the utility model has the following advantages: 1, the use of liquid nitrogen storage tank, makes drying medium change nitrogen into by original air, decreases moisture content; 2, the use of electric furnace, makes the outlet temperature of heat medium reach 150 DEG C, improves heating-up temperature, ensure that heating effect; 3, the setting of gas distribution pipe in drying chamber, makes pearlife be heated heat evenly, avoids, only from the phenomenon absorbed by top pearlife after bottom heating causes humid air to rise, ensureing heating effect; 4, the use of water ring vacuum pump, discharges in time by the moisture after heating, solves only heating and problem that moisture cannot be discharged, avoids after water vapour cools simultaneously and again absorbed by pearlife.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1, liquid nitrogen storage tank; 2, electric furnace; 3, drying chamber; 4, water ring vacuum pump; 5, gas distribution pipe.
Detailed description of the invention
See Fig. 1, a kind of pearlife drying device, is comprised the liquid nitrogen storage tank 1, electric furnace 2 and the drying chamber 3 that are connected successively by metal hose, is provided with gas distribution pipe 5 in drying chamber 3, and the top of drying chamber 3 connects water ring vacuum pump 4 by metal bellows; Drying chamber 3 top is also provided with drain, bottom is provided with drain hole.
Operation principle: 1, drying chamber is evacuated to absolute pressure 0.1MPa, utilizes pressure reduction to be directly drawn in drying chamber by pearlife in pearlife storage tank; 2, open liquid nitrogen storage tank outlet valve, open electric furnace simultaneously, adjustment setting parameter outlet temperature is 150 DEG C; 3, heat drying chamber with nitrogen, the air of moisture content is extracted out by open water ring vacuum pump simultaneously; 4, drying complete after closedown liquid nitrogen storage tank and electric furnace; 5, open drying chamber drain and pearlife outlet valve, pearlife is evacuated to vacuum interlayer.
By the utility model, the beneficial effect obtained is: practice shows, 1 60m
3low-temperature (low temperature) vessel, as the pearlife with undried process, the minimum needs of evacuated time 30 days; Use the pearlife after vacuum drying treatment, evacuated time on average only needs 15 days, substantially reduces the manufacturing cycle, reduces production cost.
In the middle of this covering device puts into production, after adopting this device by the information of actual feedback, work is very smooth, reach Expected Results, ensure for a large amount of subsequent products provides technology, remarkable in economical benefits improves.
Below be only exemplary embodiments of the present utility model, those skilled in the art can do suitable modification and improvement completely on its basis, but identical with the utility model substance, fall into protection domain of the present utility model equally.
