The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explain
With reference to Fig. 1, this press filtration drying plant comprises pressure-filtering tank 19, discharge tank 15 and shaft 11; Pressure-filtering tank 19 is provided with material inlet 1, press filtration gas feed 4 and vacuum port 2; Discharge tank 15 is positioned at pressure-filtering tank 19 bottoms, and discharge tank 15 communicates with pressure-filtering tank 19, and discharge tank 15 is provided with liquid material outlet 18; One end of shaft 11 is arranged in pressure-filtering tank 19 and discharge tank 15; The other end is connected with cycloidal-pin wheel decelerator 3; Be positioned on the shaft 11 at pressure-filtering tank 19 places and be connected with press filtration paddle 12, be positioned on the shaft 11 at discharge tank 15 places and be connected with discharging paddle 16, have angle between press filtration paddle 12, discharging paddle 16 and the horizontal plane; Both acute angle also can be an angle, and press filtration paddle 12 is identical with discharging paddle 16; Be provided with the chuck 14 of boring in the outside of pressure-filtering tank 19; Have Steam Heating import 13 and Steam Heating outlet 8 on the chuck 14; Chuck 14 inside are provided with helical form hot pressing filter gas pipeline 6, and the output 5 of hot pressing filter gas pipeline 6 is connected with press filtration gas feed 4.The bottom of discharge tank 15 also is provided with press filtration screen 9, and is having press filtration gas backwash import 10 under the press filtration screen 9 and on the discharge tank 15.
Below, be example to adopt nitrogen, explain that it uses step:
First step press filtration: open liquid material outlet 18 earlier, the solid-liquid compound is pressed into pressure-filtering tank 19 from material inlet 1, close material inlet 1 after finishing, then nitrogen is got into pressure-filtering tank 19 from press filtration gas feed 4, the beginning press filtration.Chuck 14 is then opened in hot pressing filter if desired, opens Steam Heating import 13, sends into steam, and with steam intensification hot pressing filter gas pipeline 6, steam is from Steam Heating outlet 8 outputs; Send into nitrogen from hot pressing filter gas feed 7 then, nitrogen is exported from hot pressing filter gas vent 5 through hot pressing filter gas pipeline 6, and from press filtration gas feed 4, gets into pressure-filtering tank 19.Like this, the liquid in the solid-liquid compound is pressed onto through liquid material outlet 18 and is equipped with storage tank in addition.
If desired to being positioned at pressure-filtering tank 19 bottoms and corner; And the material that does not stir as yet in the discharge tank 15 carries out further pressure-filteration drying; Can close press filtration gas feed 4; Open press filtration gas backwash import 10 then, nitrogen gets into through press filtration screen 9 backs, and the liquid in the solid-liquid compound is further extruded.
Afterwards, when being depressed into the no liquid outflow, close press filtration gas feed 4 and liquid material outlet 18, or close press filtration gas backwash import 10 and liquid material outlet 18.
The oven dry of second step: open vacuum mouth 2 vacuumizes.If the product bake out temperature, is then opened the steam warming-in-water below 100 ℃ and is got into and from Steam Heating import 13 outputs through Steam Heating outlet 8; If the product bake out temperature requires more than 100 ℃, then let steam get into from Steam Heating outlet 8 outputs from import 13.At this moment, control temperature requiredly, open cycloidal-pin wheel decelerator 3,, shaft 11 is turned clockwise with the speed that per minute 10 to 50 changes, then make upwards upset of material, make it even oven dry if the angle that has between discharging paddle 16 and the horizontal plane is an acute angle.
The 3rd walks out of material: open siccative discharge door 17, shaft 11 is rotated counterclockwise with the speed that per minute 10 to 50 changes, material is extruded downwards and through siccative discharge door 17.
