Operation principle
When the utility model is used, rotarily opening lid compressing member 28, the handle rotation direction of opening lid compressing member 28 is opened The outside of lid 18 is detached from the two, and opening lid 18 is above carried, opening lid 18 together with electric telescopic rod and electric telescopic rod below It squeezes cage 8 to propose inside tank body 1 together, pulls open the slide fastener 16 squeezed on cage 8, open and open mesh sheet 15, into extruding cage 8 Portion inserts raw material to be extracted;
The realization of work is carried in opening lid 18, can also be connected above opening lid 18 corresponding by manually carrying out Automatically or semi-automatically elevating mechanism, by manual operation elevating mechanism realize opening lid 18 rise and fall, and then save Manpower;
Generally use this device when, raw material is transported to by conveying mechanism near tank body 1, can save in this way manpower and Squeeze cage 8 and electric telescopic rod 19 without dismounting, if it is distant apart from raw material to squeeze cage 8, can also will squeeze cage 8 with it is electronic Telescopic rod 19 is opened at buckle 30, after filler, then will be squeezed cage 8 and is retightened with the buckle 30 of electric telescopic rod 19 It is good;
After filler, drawing slide fastener 16, opening lid 18 together with electric telescopic rod 19 is returned again and is attached to tank body 1 again On, squeeze cage 8 enter tank body 1 inside again frame above the port 17 of supporting plate 9;
Feed inlet 5 is connected with Extraction solvent transfer pipeline, after injecting Extraction solvent to the inside of tank body 1 by feed inlet 5, Start motor 4, electric telescopic rod 19, motor 4 drives the Extraction solvent in 3 Stirring tank body 1 of agitating shaft, electric telescopic rod 19 It stretches in the vertical direction, stripper plate 12 is pushed to move down when electric telescopic rod 19 extends, stripper plate 12 squeezes in folding process Extraction raw material squeezes out the Extraction solvent entered in extraction raw material from extraction raw material, the Extraction solvent squeezed out from extraction raw material In the active ingredient containing high concentration, the low concentration region of surrounding can be diffused into along with the flowing of Extraction solvent;Stripper plate 12 The pressure to extracting raw material can be removed when moving up, new proposition solvent, which can enter in extraction raw material, dissolves active ingredient, works as electricity Dynamic telescopic rod 19 repeats extrusion process when extending, the squeezing action of stripper plate 12 can accelerate Extraction solvent and be arranged from extraction raw material Go out, and then accelerate extraction rate;
After electric telescopic rod 19 works a period of time, some raw materials can be adhered on hard filter screen 13, can be utilized Nozzle 10 carries out hard filter screen 13 rough cleaning, and detailed process is:
Open the circulation pump 11 simultaneously opens the valve 31 in respective line, and entering the Extraction solvent of discharge port 6 can recycle Along Pipeline transport to nozzle 10 under the power effect of pump 11, the nozzle of nozzle 10 extracts molten to the base injcction of hard filter screen 13 Agent,, can be from hard after some raw materials being adhered on hard filter screen 13 are sprayed since Extraction solvent sprays from bottom to top It is detached from filter screen 13, into squeezing inside cage 8, so as to reduce the raw material adhered on hard filter screen 13, so as to reduce hard Filter screen 13 takes out the cleaning frequency of cleaning out of tank body 1;Mistake of the Extraction solvent before circulating pump 11 is entered Jing Guo filtration members 20 Filter, circulating pump 11, nozzle 10 are all not easily susceptible to the blocking of raw material residue;
Cleaning action can be synchronous with the expanding-contracting action of electric telescopic rod 19, can also work and finish in electric telescopic rod 19 After start, according to actual use situation concrete operations.
After squeezing the raw material extraction in cage 8, the upper actuating for repeating opening lid 18 is made, and will squeeze cage 8 and is carried out of tank body 1 Go out, unzip 16, clean out raw material therein, due to squeezing the side wall of cage 8 using flexible filter net 14, by hard filter screen 13 above carry and are rotated to 15 direction of mesh sheet is opened, and raw material can discharge, so when clearing up raw material, buckle 30 is opened or do not opened It is automatic to convey if not opening buckle 30, the preferably transmission belt in the installation discharging of the lower section of tank body 1 to simplify operation The raw material finished is extracted, saves time and manpower.
1 embodiment of the utility model is described in detail, but the content is only the utility model above Preferred embodiment, it is impossible to be construed as limiting the scope of the utility model.It is all to be made according to application scope of the utility model All the changes and improvements etc., should all still belong within the patent covering scope of the utility model.
