Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is internal structure schematic diagram of the present invention;
Fig. 2 is surface structure schematic diagram of the present invention.
Detailed description of the invention
With reference to Fig. 1, a kind of liquid aluminium polychloride low-pressure boiled solidification equipment provided by the invention, comprise material bin 1, described material bin 1 is provided with charging aperture 2, discharging opening 3, and preferably, described charging aperture 2 is provided with flow-stop valve 22, and described discharging opening 3 is provided with seal cover 23.
The below of material bin 1 is provided with the heater 4 into material bin 1 heat supply, and be provided with steam (vapor) outlet 5 above described material bin 1, described steam (vapor) outlet 5 is connected with a jet chimney 6, and described jet chimney 6 is connected with the vacuum extractor 7 for extracting material bin 1 inner air.Because liquid produces vapour pressure when volatilization, when vapour pressure (saturated vapour pressure) equals extraneous pressure, liquid will seethe with excitement, and temperature is now exactly the boiling point of liquid.Therefore, extracting material bin 1 internal gas pressure by installing vacuum extractor 7 in the present embodiment, improving the vacuum in storehouse thus effective boiling point reducing liquid material, Separation of Solid and Liquid speed being accelerated, improves rate of drying.
Described material bin 1 inside is also provided with the agitator 8 for pulverizing curing material, described agitator 8 comprises the turning cylinder 19 that is arranged on material bin 1 upper wall and for controlling the motor 20 that turning cylinder 19 rotates, described motor 20 is connected with turning cylinder 19, and described turning cylinder 19 is provided with blade 21.
Temperature sensing device 9, air pressure sensing device 10, liquid level sensing device 11 are installed in described material bin 1, described temperature sensing device 9, air pressure sensing device 10, liquid level sensing device 11 are connected with microcomputer control circuit 12, material bin 1 outer wall is provided with control panel 13 and display screen 14, described control panel 13 and display screen 14 are electrically connected with microcomputer control circuit 12, and concrete please refer to Fig. 2.Operator can control the operation of solidification equipment by control panel 13 and arrange running parameter, such as, control inlet amount, preset storehouse internal gas pressure and preheating degree etc.; Operator can check the ruuning situation of solidification equipment by display screen 14, such as, in storehouse real-time air pressure, temperature etc.
