A kind of lime slaking dosing pay-off
Technical field
The present invention relates to water-treatment technology field, particularly a kind of lime slaking dosing pay-off.
Background technology
Existing lime slaking dosing technique generally adopts following two kinds of modes: one is that refined lime is winched to milk of lime preparation vessel by warehouse, make the lime milk solution that concentration is 20%, then with pump defeated milk of lime is delivered to dirty acid, one section, two sections, three sections neutralizing wells neutralize.Two is that the refined lime of refined lime tank is delivered to Calcified pond, refined lime contacts with water and soaks in pond, grab to intermediate bin with grab bucket after naturally cooling for some time, wash with water again and enter lime slaking machine, being separated of lime mud and milk of lime is carried out finally by spiral of slagging tap, milk of lime is sent to neutralizing well and neutralizes, and lime mud drops in slag bucket, regularly transports with automobile; Or by the refined lime of refined lime tank by the first elephant trunk enter steel basin add water stir formed lime white, lime white enters lime white settling tank precipitation through the second elephant trunk again, the milk of lime on settling tank upper strata is through screen filtration, enter milk of lime pond, milk of lime in milk of lime pond is sent to neutralizing well neutralize, lime mud in lime white settling tank regularly clears out through digging machine or craft, transports with automobile.Adopt the first digestion dosing technique to adopt refined lime to cause cost high and the large defect of lime airborne dust, adopt the second digestion dosing technique to have lime waste serious, and the defect such as equipment plugging is frequent, failure rate is high.Existing lime dosing feeding adds by lifting or manually pushing away dolly, and exist reinforced uneven, time-sharing type charging, does not have continuity, affects digestion effect.
Summary of the invention
The object of the invention is the above-mentioned deficiency overcoming prior art, and provide a kind of whole flow process smooth and easy, realize supplying feeding continuously, the lime slaking dosing pay-off that working efficiency is high.
Technical scheme of the present invention is:
A kind of lime slaking dosing pay-off, it comprises: lime pay-off, lime slaking unit, milk of lime separating unit and lime dosing unit; Wherein lime slaking unit, comprises cylindrical shell, and cylindrical shell is provided with opening for feed and discharge port, and inner barrel is divided into successively from opening for feed to discharge port: buffer zone, homogeneous district, newborn slag disengaging zone, dreg discharging area, Lao Zha district; Unslaked lime is digested to milk of lime sand water mixture after lime slaking unit, and milk of lime sand water mixture flows out from discharge port; Milk of lime separating unit, is separated into milk of lime and lime mud by the milk of lime sand water mixture flowed into from discharge port; Milk of lime is sent by pumping in the neutralizing well of lime dosing unit and neutralizes, and lime pay-off is the device that can advance lime, and it is arranged on the below in refined lime tank, and the outlet of its lime is positioned at directly over the opening for feed of lime slaking unit.
The further technical scheme of the present invention is: described lime feeding unit comprises feed auger bar cover, feed auger bar and drive-motor, and feed auger bar is the axle with spiral conveying blade; Feed auger bar cover is the sleeve matched with feed auger bar, and the upper lateral part of its charging one end is provided with feed entrance, and the feed auger bar cover the other end has lime outlet; Feed auger bar is movably arranged in feed auger bar cover, and feed auger bar is connected with drive-motor; The lime outlet of screw rod cover is positioned at directly over the opening for feed of lime slaking unit.
The further technical scheme of the present invention is: described feed auger bar is movably arranged in feed auger bar cover by bearing and axle sleeve, and feed auger bar is connected with drive-motor by transmission rig.
The further technical scheme of the present invention is: the other end of described feed auger bar is movably arranged in feed auger bar cover by rear bearing and rear axle housing, and feed auger bar is connected with supporting device by transmission rig.
The further technical scheme of the present invention is: the transmission rig that described feed auger bar is connected with drive-motor is with speed control unit.
The beneficial effect of hinge structure of the present invention is:
1, pay-off one endfeed, one end discharging, make flowing more smooth and easy, realizes the object of continuous fuel, improve working efficiency;
2, feeding unit can uniformly continous feed, and can be controlled the speed of feed by speed change mechanism, thus can control feeding amount well as required, and namely pay-off realizes Full automatic feed mode, has saved labor force.
