Description
The present invention relates to the black liquor extraction equipment in the paper technology, refer in particular to the high concentration that is mainly used in the improvement of paper industry solution contaminated wastewater, a kind of extractor of high-temperature black liquor.It also can be used for other industrial material extrusion dehydration, concentrate etc.
Retrieval finds out, is applicable in the commercial Application that performance equipment better, that efficient is higher does not appear in the newspapers in the concentrated black liquid extractor of alkaline straw-pulp.The primary raw material of the present paper industry of China is a wheat straw, and with alkaline cooking.Because physics, chemical characteristic that alkaline wheat straw pulp is special, as: drainability is poor, permanganate number is low, silicone content is high, viscosity is big etc.Existing wheat straw slurry is in extracting the concentrated black liquid process equipment, for a long time, the extrusion dehydration problem is provided with always and obtains satisfied solution, particularly can't overcome the wheat straw slurry and produce the phenomenon of skidding in being extruded process, and this all feels at a loss what to do to many technology personnel.For attempting sort this problem out, relevant technology personnel once had the scheme of multiple technical solution problem, as: acroll press washer also once occurred, but proved in producing that it was only applicable to wood pulp, and alkaline straw-pulp is skidded, stops up and can not use; As: Var-nip press to concentration higher ball blanking can not directly use, need thin up thereby efficient to reduce greatly, and the fiber loss rate is big, fragile, after the seventies, promptly progressively eliminated.In the world, therefore developed country is not suitable for the technology and equipment that straw pulp is produced because without papermaking straw pulp yet.So never have a kind of high efficiency concentrated black liquid extracting method and equipment so far.So it is that main filter wash method is extracted black liquor that paper-making industry for avoiding the concentrated black liquid contaminated environment, has to adopt dilution, displacement washing, make institute's black liquid consistency of carrying rare, but water consumption is huge.And handle this a large amount of rare black liquor, and just become the huge financial burden in paper mill, need the treatment facility of investing in of tens million of units, operating cost is also extremely high.Therefore this will cause the large-scale paper plant that this investment capacity and ability to bear are arranged and reduce its economic benefit significantly.And be not judged to because of having this investment capacity and ability to bear for middle-size and small-size paper plant: contaminated environment, there is not the value of improvement, only face the destiny of closing down.
Purpose of the present invention just provides a kind of, extracting machine for papermaking thick black liquid that efficient high good than existing black liquor extraction equipment performance.
The object of the present invention is achieved like this: it comprises shell, press filtration dish, isolating cylinder, transmission mechanism, motor and connector, fixture and seal extracting machine for papermaking thick black liquid; Shell is a cylindrical shell, and charging aperture is arranged at its top, and discharging opening and leakage fluid dram are arranged at the bottom; It is characterized in that: outer casing inner wall is installed with support bar, and support bar one end is fixed on the shell, and other holds affixed isolating cylinder, and isolating cylinder is fixed in the middle of the shell by support bar; The press filtration dish is two and is provided with sieve aperture and is respectively equipped with transmission mechanism by its rotation of driven by motor; Press filtration dish opposite shell center line is that relative tilt is installed in the enclosure in the isolating cylinder two ends, and promptly press filtration dish shaft axis and horizontal line form angle α; Isolating cylinder is a seal, and its both ends of the surface and press filtration dish card match and be gapped; Space between the two press filtration dishes is separated to form two spaces of upper and lower V1V2 and V1＞V2 by isolating cylinder.
Above-mentioned design, the wheat straw slurry enters the V1 space by charging aperture, rotation synchronously under the clamping of two press filtration dishes, progressively be pressed in the less SPACE V 2, having taken off the slurry behind the black liquor is promptly emitted by discharging opening, and concentrated black liquid is filtered outside the press filtration dish by press filtration riddle hole, is discharged by leakage fluid dram, can move continuously.Prototype test has reached the effect that performance is good, efficient is high, has solved a great problem of China's paper-making industry.
Below by drawings and Examples the present invention is described further again.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the internal structure schematic diagram of A-A after shedding right side press filtration dish and shell among Fig. 1.
As shown in Figure 1, the present invention includes shell 1, press filtration dish 2, isolating cylinder 3, transmission mechanism 4, motor 5 and be connected and fixed seal: shell 1 is a cylindrical shell, and charging aperture 6 is arranged at its top, and discharging opening 7 and leakage fluid dram 8 are arranged at the bottom.Shell 1 inwall is installed with support bar 9a, 9b and makes isolating cylinder 3 be fixed on shell 1 centre by it; Press filtration dish 2 is two and is provided with sieve aperture 10, and it is done in the same way, rotates synchronously by motor 5 drives respectively; Press filtration dish 2 can tapered square position shape or symmetrical arc surfaced; The shape of selecting to change press filtration dish 2 can reach change compression ratio V1: V2.The certain symmetry of its rotating shaft is installed, and with stable rotation and bearing, speed changer etc. are arranged, shaft axis 11 and horizontal line 12 α in a certain angle and angle α are 0 °＜α＜90 °.Adjust angle α, also can change compression ratio V1: V2.Isolating cylinder 3 is the sealing drum body, by support bar 9a, 9b can adjust its installation site on the upper side or on the lower side, also can reach thus and change compression ratio V1: V2.But no matter select to adopt the press filtration dish 2 of above-mentioned which kind of shape, as being taper among Fig. 1, the card of isolating cylinder 3 both ends of the surface and press filtration dish 2 matches and certain interval is arranged, to guarantee the 2 smooth and easy rotations of press filtration dish.
As shown in Figure 2: the shell 1 of charging aperture 6 one side-lowers is provided with pusher 13.This pusher 13 can adopt by what piston 14 connecting rods 15 of driven by motor and eccentric wheel 16 were formed and finish reciprocating mechanism, positive feed.And piston cylinder 17 can be located on the brace rod 9a, makes brace rod 9a play a part to help charging simultaneously.Said mechanism has overcome the alkaline wheat straw pulp material skids, and is difficult to the difficult problem of charging.Discharging opening 7 is located at shell 1 lower support muscle 9b one side, and the B that keeps at a distance from shell 1 bottom, to guarantee the unlikely discharging opening 7 of sneaking into of concentrated black liquid.The brace rod 9b of bottom is arcuation and holds concurrently and is a part of side plate of discharging opening 7, plays the blanking effect again.
The wheat straw slurry that uses the present invention directly spherical digester to be emitted, under the condition that keeps its original temperature and concentration, squeeze and get high-temperature, high dense black liquor, can be under the prerequisite that is not less than former technology extraction rate of black liquor, using water wisely significantly, water yield saving, reduction are more than 2/3.Extraction and concentration section can save energy, economize on water more than 2/3.So just can make the large-scale paper plant of black liquor treatment measure and ability, economic benefit increases substantially, and the black liquor treatment of middle-size and small-size paper plant has had wishes and possibility.
