Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of continuous dipping catalyst cracking reactor (5) in the utility model.
The specific embodiment
Come the utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model comprises can segment raw material the stock-cutter 1 that impurity elimination is carried then, deduster 2 and transport 3, transport 3 can adopt drag conveyor, the outlet of this transport 3 connects a conveying worm 4, can add soak in the conveying worm 4 raw material is carried out preimpregnation, for preventing that soak from flowing out, the outlet of conveying worm 4 can be higher than inlet, outlet at conveying worm 4 connects a continuous dipping catalyst cracking reactor 5, this continuous dipping catalyst cracking reactor 5 can make raw material be immersed in the soak in course of conveying to react, main effect is lignin and the colloidal type material of removing in the raw material, the outlet of continuous dipping catalyst cracking reactor 5 connects a pulp-liquor separator, the outlet of this pulp-liquor separator connects the slurries after-treatment device, wherein the slurries after-treatment device comprises that the thick slurry after separating can be spurted at normal temperatures cold the spurting of discongesting discongests pot 6, this is cold to spurt and discongests pot 6 and be provided with high pressure admission pipeline and quck-opening valve, cold spurting discongested pot 6 outlet and connect a jetting storehouse 7, discongest the thick slurry of putting in the pot 6 after slurries separate cold spurting during use, pressurize by the high pressure admission pipeline, open quck-opening valve more rapidly, can realize that normal temperature discongests, the outlet of jetting storehouse 7 connects a press master 8, further realizes the feed liquid separation thereby the outlet of press master 8 connects a thin press master 9.
As shown in Figure 2, wherein continuous dipping catalyst cracking reactor 5 has comprised three drag conveyors, the feeding end 10 of the first wherein the highest drag conveyor connects the outlet of described conveying worm 4, the feeding end 10 of second drag conveyor in the middle of the discharge end 14 of this first drag conveyor connects, the discharge end 14 of this second drag conveyor connects the feeding end 10 of the 3rd minimum drag conveyor, the discharge end 14 of the 3rd drag conveyor connects a pulp-liquor separator, clearly, under the assembled condition that meets the corresponding connection of above-mentioned head and the tail, continuous dipping catalyst cracking reactor 5 also can be made of more groups of drag conveyors, is advisable with the 10-15 group usually.
As shown in Figure 2, wherein each drag conveyor all places in the casing 11 that fills soak, and the discharge end 14 of drag conveyor is higher than feeding end 10, thereby avoids that soak flows out outside the casing 11 in course of conveying.
As Fig. 2, shown in 3, three drag conveyors are placed from top to bottom successively among the figure, be provided with passive support in its both sides, all casings 11 all can not have loam cake, with the first the highest drag conveyor is example, its scraper chain rotates in a clockwise direction, thereby make raw material 13 conveyings below the effect lower edge of scraper plate casing 11, fall the feeding end 10 that enters second drag conveyor to higher discharge end 14 and repeat said process, constitute in the drag conveyor of continuous dipping catalyst cracking reactor 5 at all, rotation direction by the control scraper chain, raw material all 13 is being carried below the casing 11 under the effect of scraper plate, thereby guarantee that raw material fully contacts with soak, as shown in Figure 3, in the middle of the scraper chain of each drag conveyor, be provided with dividing plate 12, and make the liquid level of soak be higher than dividing plate 12, thereby effectively avoid raw material to float on the soak and can't fully soak into.
