During present embodiment work, pan feeding distributor 1 is assigned to black water in the material feeding region 12 uniformly, further stable equilibrium by contraminated zone 7, be advanced into the top of underflow enrichment region 5 for 3 times by the pan feeding descender, be advanced into the bottom of underflow enrichment region 5 under the bulky grain in this black water, water and tiny particle are advanced in the enrichment region 11 on then; Up black water further distributes by the up district 4 of pan feeding, enters uniformly in the reverse precipitation inclined tube device 9, is separated with tiny particle at this water; The tiny particle that is separated is assembled the bottom that is advanced into underflow enrichment region 5 under the agglomerating back in reverse precipitation inclined tube device 9, the clear water that is separated up by clear water zone 2 further stablize homogenizing, collect the back discharge by clear water gathering-device 8; The underflow that enters the bottom of underflow enrichment region 5 is collected the underflow discharging mouth of pipe discharge of an installation by mud scraper 6; So finished concentrating clarifying work to black water.
Embodiment 2, in Fig. 2, the high-efficiency pipe chute thickener of another kind of intermediate feed, its pan feeding distributor 1, material feeding region 12, underflow enrichment region 5, mud scraper 6, the underflow delivery pipe, clear water zone 2, the up district 4 of pan feeding, the shape of clear water gathering-device 8 grades, structure, material therefor, effect are described like embodiment 1.The main shape of reverse precipitation inclined tube device 9, structure, material therefor, effect etc. are also as described in the embodiment 1, different is that the reverse precipitation inclined tube device 9 in the enrichment region 11 changes the side direction installation among Fig. 1, and corresponding install the precipitation pool wall that inclined tube device contacted partly make with the inclined tube device of installing need the inclination angle adaptive angle, with the stability after the installation that improves reverse precipitation inclined tube device 9.
During present embodiment work, job step, method, principle are described like embodiment 1, different is that the reverse precipitation inclined tube device of installing in the work 9 can bear the pressure that more coal slimes produce, and than embodiment 1 described reverse precipitation inclined tube device resistance to compression, is difficult for the accident of striking the beam.
Embodiment 3, in Fig. 3, the high-efficiency pipe chute thickener of the third intermediate feed, its pan feeding distributor 1, material feeding region 12, enrichment region 11, underflow enrichment region 5, mud scraper 6, the underflow delivery pipe, clear water gathering-device 8, the shape of reverse precipitation inclined tube device 9 grades, structure, material therefor, effect are described like embodiment 2.Different is that clean water collecting groove 13 is arranged on two shared pool wall tops at material feeding region 12 and enrichment region 11 among Fig. 2, and described clear water gathering-device 8 is communicated with this clean water collecting groove 13.
In present embodiment when work,, job step, method, principle are described like embodiment 2, and different is in the work, and clear water gathering-device 8 collected water compile the back by clean water collecting groove 13 again discharges.
Based on same principle and method, the utility model also can be installed in the material feeding region among the above embodiment 12 or on the whole plane of middle and lower part and precipitate inclined tube or sloping plate unit 10 in the same way, as Fig. 4, with further homogenizing with stablize descending black water, and black water carried out preformed precipitate, do so also and can reach same purpose, and help improving some effects.
Based on same principle and method, the utility model also can be installed more high-intensity inclined tube or the sloping plate unit of precipitating in the same way in the material feeding region among the above embodiment 12 or on the whole plane of middle and lower part, with further raising anti-pressure ability, do the effect and the purpose that also can reach same like this.
Embodiment 4, the rectangle structure that use existing coal washery is from the reverse flow pipe chute thickener (as Fig. 5-8) of a side charging, the enrichment region that mostly is owing to its mud scraper top correspondence, there is not the condition that the mud scraper head is installed, at the middle part, body two ends, pond of positive rectangle structure two projections are set so have to, head and tail are installed.Therefore the type of the overlooking shape of existing pipe chute thickener is not positive rectangle structure.Because the mud scraper 6 top correspondences of the high-efficiency pipe chute thickener of intermediate feed of the present utility model is material feeding region 12, there is pool wall its both sides, need use the pool wall at position when therefore designing by local reinforcement fitting machine head and tail, can cancel the projection that former installation head and tail need, the type of the overlooking shape of the high-efficiency pipe chute thickener of intermediate feed is really made positive rectangle structure.Do further to simplify the civil engineering difficulty like this, reduce floor space, more help the layout of relevant auxiliary facility such as pump house, can reach the effect that reduces to invest.
Embodiment 5, the rectangle structure that use existing coal washery is from the reverse flow pipe chute thickener (as Fig. 5-8) of a side charging, corresponding a part of inclined tube is taken away above generally need be mud scraper when the processing accident, as service aisle, after finishing to accident treatment, again this part inclined tube is installed, done like this and can cause inclined tube badly damaged, influenced the life-span of inclined tube.Because the mud scraper 6 top correspondences of the high-efficiency pipe chute thickener of intermediate feed of the present utility model is material feeding region 12, in the two ends in this district or the position that needs inclined tube is not installed during design, reserve one or more working spaces, do to have influence on whole structure like this, therefore after accidents happened, reach and handle conveniently, and motionless mounted inclined tube, can not cause inclined tube to damage, improve the inclined tube life-span, simplify work.
The utility model discloses a kind of high-efficiency pipe chute thickener of intermediate feed; though more than enumerated less embodiment; but for those of ordinary skill in the art; some remodeling that the utility model is done, improvement, replacement etc.; perhaps above-mentioned embodiment is done any combination and is changed, and all drops within the protection domain of the present utility model.
