The invention has the beneficial effects as follows: the invention provides a kind of liquid aluminium polychloride low-pressure boiled solidification equipment, by continuous heating and vacuumizing, make the material bin internal gas pressure keep low scope, low pressure is impelled the boiling point lowering of water.This device can make the moisture in the material evaporate in a large number at low temperatures, makes the liquid aluminium polychloride fast dewatering, until solidify.The present invention has simple in structure, has automatic control, enhances productivity, the advantages such as save energy, reduction product cost, is fit to large-scale promotion and uses.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention;
Fig. 2 is surface structure synoptic diagram of the present invention.
Embodiment
With reference to Fig. 1, a kind of liquid aluminium polychloride low-pressure boiled solidification equipment provided by the invention comprises material bin 1, and described material bin 1 is provided with opening for feed 2, discharge port 3, and preferably, described opening for feed 2 is provided with flow-stop valve 22, and described discharge port 3 is provided with sealing cover 23.
The below of material bin 1 is provided with the heating unit 4 into material bin 1 heat supply, and described material bin 1 top is provided with vapour outlet 5, and described vapour outlet 5 is connected with a steam-pipe 6, and described steam-pipe 6 is connected with for the vacuum extractor 7 that extracts material bin 1 inner air.Because liquid produces vapour pressure in volatilization, when vapour pressure (saturation vapour pressure) equaled the pressure in the external world, liquid will seethe with excitement, and the temperature of this moment is exactly the boiling point of liquid.Therefore, extract material bin 1 internal gas pressure by vacuum extractor 7 is installed in the present embodiment, thereby the vacuum tightness in the raising storehouse effectively reduces the boiling point of liquid material, and solid-liquid separation speed is accelerated, and improves drying rate.
Described material bin 1 inside also is equipped with for the agitator 8 of pulverizing curing material, described agitator 8 comprises the rotation axis 19 that is installed in material bin 1 upper wall and is used for the motor 20 that control rotation axis 19 rotates, described motor 20 is connected with rotation axis 19, and described rotation axis 19 is provided with blade 21.
Temperature sensing device 9, air pressure sensing device 10, liquid level sensing device 11 are installed in the 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, be provided with control panel 13 and display screen 14 at material bin 1 outer wall, described control panel 13 and display screen 14 are electrically connected with microcomputer control circuit 12, the concrete Fig. 2 that please refer to.The operator can control the operation of solidification equipment and working parameter is set by control panel 13, for example controls inlet amount, default storehouse internal gas pressure and preheating degree etc.; The running condition that the operator can check solidification equipment by display screen 14, for example real-time air pressure, temperature etc. in the storehouse.
In concrete use procedure, liquid aluminium polychloride enters material bin 1 by opening for feed 2, the degree of depth of liquid level sensing device 11 tracer liquid polymerize aluminum chlorides, and when reaching default liquid level, flow-stop valve 22 autoshutdowns of opening for feed 2 stop charging.
After stopping charging, open vacuum extractor 7, make the storehouse internal gas pressure be reduced to preset air pressure by vacuumizing, open heating unit 4 again, make liquid aluminium polychloride be warming up to boiling, vacuum extractor 7 continues steam in the extracting bin, makes the storehouse internal gas pressure keep low scope.
When polymerize aluminum chloride is dried to into when solid-state, turn on agitator 8, the blade 21 of agitator 8 shreds solid-state polymerize aluminum chloride one on the other, in case the solid balling, improves the ridity of solid polyaluminium chloride.
In the described material bin 1 scarfing cinder equipment 15 is installed, described scarfing cinder equipment 15 is installed in material bin 1 inside, is used for pushing the curing material that sticks in material bin 1 inwall.Preferably, described scarfing cinder equipment 15 comprises scarfing cinder dish 16, and is used for driving the power arm 17 that the scarfing cinder dish promotes back and forth, and described scarfing cinder dish 16 is connected with power arm 17, and described scarfing cinder dish 16 bottom surfaces are provided with at least one flat scraper plate 18.
