Specific implementation mode

The embodiment of the utility model is illustrated below according to attached drawing.

As illustrated in fig. 1 and 2, a kind of defoaming device for thickener, concentrator include the pulp tank 1 and walking device 3 of tubular, ore pulp Ore pulp in slot 1 includes froth bed 9, thin pulp layer 10 and dense layer 11 from top to bottom.The radius of pulp tank 1 is set according to actual condition Meter, preferably 4 ~ 5m are vertically installed with column 12 at the center of pulp tank 1, the table of the upper end of column 12 from ore pulp froth bed 9 Face is stretched out, and the side of pulp tank 1 is fixedly installed cricoid walking device track 2, and walking device 3 is radially extended along pulp tank 1, and One end is movably arranged on walking device track 2, and other end is rotatably arranged on column 12, to realize walking device 3 around pulp tank 1 Center rotating.

Defoaming device includes the spray tube being arranged on walking device 3 and drawing liquid pump 4, drawing liquid pump 4 and 1 center stand column of pulp tank The distance between preferably 3.5m, and drawing liquid pump 4 preferably use Hebei Zhong Wobeng industry Co., Ltd production model 65ZJL- 27 vertical slag slurry pump, power 11KW-4.There are vertically disposed pulp-absorbing pipe 14, pulp-absorbing pipe in the inlet communication of drawing liquid pump 4 Thin pulp layer 10 is stretched into 14 lower end, and the distance between the lower end of pulp-absorbing pipe 14 and 9 surface of ore pulp froth bed are preferably 50cm, are led to Experiment is crossed, the liquid thin pulp of the position obtains balance on pulp density and bubble content, and resultant wear and defoaming effect are best. The outlet of drawing liquid pump 4 has main conduit 5, main conduit 5 to be arranged on walking device 3 and be connected to spray tube and drawing liquid pump 4, It is enclosed with absorbent material layer 19 on main conduit 5, hyaline membrane 20 is enclosed on absorbent material layer 19, water-absorbent material can be selected normal Sponge etc..Spray tube includes lateral 6, and the outlet tube that lateral 6 is sequentially communicated by three sections forms, wherein in being located at Between one section be connected with main conduit 5 and be mutually perpendicular to main conduit 5, be in addition mutually parallel with main conduit 5 for two sections And be separately positioned on the both sides of walking device 3, every section of outlet tube be all connected to there are two nozzle 7 to carry out spray defoaming, nozzle 7 includes Interconnected straight pipe 21 and flared section 22, wherein straight pipe 21 are connected with outlet tube, and flared section 22 is in horn-like, and loudspeaker The tip of shape is connected with straight pipe 21.Every section of outlet tube is fixedly connected by several connecting rods 8 with walking device 3.

It is additionally provided with electric cabinet 13 on walking device 3, controller 18, drawing liquid pump 4 and controller 18 are provided in electric cabinet 13 Electrical connection.Breaker 15, contactor 16 and time switch 17 are additionally provided in electric cabinet 13, wherein breaker 15 preferably uses The miniature circuit breaker of model DZ47-63, contactor 16 preferably use connecing for the model CJX2s2501 of Dexia Group's production Tentaculum, time switch 17 preferably use the time switch of the model KG316T of Dexia Group's production.Breaker 15, contactor 16 and connection type and the effect of time switch 17 be the prior art, details are not described herein.

When in use, drawing liquid pump 4 extracts thin pulp by pulp-absorbing pipe 14 from thin pulp layer 10, is then fed into main conduit 5, It is flowed into three sections of outlet tubes of lateral 6, and is finally sprayed from nozzle 7, the thin pulp of ejection by main conduit 5 later It drops on froth bed 9 and smashes foam, complete defoaming.Effective defoaming radius can be determined by the length of outlet tube, at this In embodiment, defoaming radius is set to 2.5m by setting the length of outlet tube to 2.5m.For larger dense Close machine can increase the quantity of nozzle 7 while extending outlet tube length.Because defoaming does not need moment progress, therefore logical It crosses electric cabinet 13 and controls after drawing liquid pump 4 is often opened one hour and stop one hour.

Because also retaining certain rough concentrate in thin pulp, therefore it is easy to generate abrasion, especially main conduit to pipeline 5, if main conduit 5 generates leakage because of abrasion, the pressure at nozzle 7 can be caused to reduce, pressure when thin pulp sprays is not It is enough, jet length shortening is may result in, and then cause effectively to defoam radius reduction, defoaming effect weakens, serious to cause Concentrate yield reduces.Therefore such as sponge of water-absorbent material 19 is wrapped up on main conduit 5, and wraps up hyaline membrane 20 again outside it, If when abrasion breakage occurs for main conduit 5, thin pulp is flowed into sponge and is absorbed by the sponge from breakage, can temporarily keep away Exempt from thin pulp largely to outflow, to keep the pressure of nozzle 7, while can observe leak point in time through hyaline membrane 20, thus and When main conduit 5 is repaired.Similar, thin pulp splashes around at nozzle 7, can cause to wear to the outlet of nozzle 7, In wet condition, the loss rate of nozzle 7 can be further speeded up, therefore flared section 22 is arranged, and make thin pulp along flared section 22 Inner wall splashes outward, will not cause to be seriously worn to the outlet of flared section 22, extend the service life of nozzle 7.

The utility model is defoamed by the thin pulp in extraction concentrator pulp tank 1 in place, compared to profit Although the method efficiency defoamed with clear water is lower, water resource, clean environment firendly can be effectively saved.Pass through simultaneously Electric control box device is set, additionally it is possible to automatically control the working time, reduce manpower consumption, repair and maintenance is also very convenient.
