Abstract
The invention belongs to the technical field of preparation equipment and provides a continuous ore discharge type centrifuge. The continuous ore discharge type centrifuge comprises a rack, a motor, a hollow shaft, a centrifugal rotary drum, a variable extraction pipe, a tailing tank, a concentrate tank, a feed pipe, a backwash water pipe and an air inflow pipe. The centrifugal rotary drum comprises an inner sleeve and an outer sleeve. A cavity is formed by the inner sleeve and the outer sleeve. Separation tanks are distributed on the inner sleeve of the centrifugal drum. Tangential water inlets are formed in the concave bottom faces of the separation tanks. The variable extraction pipe is installed on the outer side wall of the centrifugal rotary drum. The variable extraction pipe is provided with a pneumatic control switch. A backwash water pipe joint is communicated with the cavity formed by the inner sleeve and the outer sleeve. An air inflow pipe joint is communicated with the pneumatic control switch. Thus, under the condition that non-halt operation is achieved, separated concentrates are discharged at any time, time is saved, and production efficiency is greatly improved.
Description
Technical field
The present invention relates to preparation equipment technical field, particularly relate to a kind of discharge centrifuge continuously.
Background technology
Water jacket centrifuge is one of Modern Heavy optional equipment.Because its disposal ability is large, sort particle size range wide, Operation and Maintenance is simple, as to roughly select or selected being widely used in sorts gold, tin, tungsten, titanium, red iron etc.But; the centrifugal beneficiating equipment of formula manually or automatically of current use is interrupted to produce; need to stop machine, carry out concentrate cleaning and discharge, only need after equipment operation stops completely in production; again by artificial or equipment ejaculation ore deposit; after drained concentrate again start carry out ore dressing, this process is generally 1 ~ 4 hour/time according to the different situations cycle, period shuts down frequently, ejaculation ore deposit, start cause the plenty of time to waste; workman's working strength is also higher, and beneficiating efficiency is also very low.
In summary, obviously there is inconvenience and defect in actual use in prior art, so be necessary to be improved.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of discharge centrifuge continuously, it can be interrupted under not shutdown situation discharges concentrate, and can regulate arbitrarily the ejaculation ore deposit cycle according to the difference of head grade and composition.
To achieve these goals, the invention provides a kind of discharge centrifuge continuously, comprise frame, motor, hollow shaft, centrifugal basket, variable extraction tube, tail-box, concentrate hopper, feed pipe, recoil water pipe, air inlet pipe, described motor is fixed in frame, and described motor is connected with described hollow shaft by belt transmission, described hollow shaft is rotatably installed in described frame by bearing arrangement, described hollow shaft top is fixedly connected on bottom described centrifugal basket, described centrifugal basket comprises inner sleeve and overcoat, described inner sleeve and overcoat form a cavity, put in described centrifugal basket and be distributed sorting groove, the concave bottom surface of sorting groove is provided with tangential inlet opening, described variable extraction tube is installed on described centrifugal basket lateral wall, the mouth of pipe of described variable extraction tube leads directly to sorting groove and described inlet opening is spaced, described variable extraction tube is provided with pneumatic control switch, concentrate hopper is arranged with outside described variable extraction tube, tail-box is arranged with outside described concentrate hopper, described concentrate hopper, tail-box is all fixed in frame, the lower end of described hollow shaft connects back-flushing pipe joint and air inlet pipe joint, described back-flushing pipe joint is communicated with the cavity that described inner sleeve and overcoat are formed, pneumatic control switch described in described air inlet pipe fittings.
According to continuous discharge centrifuge of the present invention, described back-flushing pipe joint and air inlet pipe joint are double-channel rotatable pipe overall structure, and admitting pipe joint is communicated with the cavity that described inner sleeve and overcoat are formed, pneumatic control switch described in described air inlet pipe fittings.
According to continuous discharge centrifuge of the present invention, described pneumatic control switch is provided with periodic adjustment control device.
The switch of variable extraction tube is controlled by air pressure; achieve under non-stop-machine operational situation; at any time the concentrate sub-elected is discharged; self-timing control can be carried out or manually control at any time to discharge; and the ejaculation ore deposit cycle can be regulated arbitrarily according to the difference of head grade and composition; simple, convenient, save the time, substantially increase production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
See Fig. 1, the invention provides a kind of discharge centrifuge continuously.This continuous discharge centrifuge comprises frame 1, motor 2, hollow shaft 3, centrifugal basket 4, variable extraction tube 5, tail-box 7, concentrate hopper 6, feed pipe 8, recoil water pipe 10, air inlet pipe 9.Motor 2 is fixed in frame 1 and is connected with hollow shaft 3 by belt transmission, hollow shaft 3 is rotatably installed in described frame 1 by heavy bearing device 12, described hollow shaft 3 top is fixedly connected on bottom centrifugal basket 4, centrifugal basket 4 comprises inner sleeve and overcoat, described inner sleeve and overcoat form a cavity, put in centrifugal basket 4 and be distributed sorting groove, the concave bottom surface of sorting groove is provided with tangential inlet opening, variable extraction tube 5 is installed on centrifugal basket 4 lateral wall, the mouth of pipe leads directly to sorting groove and described inlet opening is spaced, variable extraction tube 5 is provided with pneumatic control switch, concentrate hopper 6 is arranged with outside variable extraction tube 5, tail-box 7 is arranged with outside concentrate hopper 6, concentrate hopper 6, tail-box 7 is all fixed in frame 1, the lower end of hollow shaft 3 connects recoil water pipe 10 joint and air inlet pipe 9 joint, the cavity that described in recoil water pipe 10 fittings, inner sleeve and overcoat are formed, pneumatic control switch described in air inlet pipe 9 fittings.
Further, recoil water pipe 10 joint of the present invention and air inlet pipe 9 joint are double-channel rotatable pipe overall structure, the cavity that described in recoil water pipe 10 fittings, inner sleeve and overcoat are formed, pneumatic control switch described in described air inlet pipe 9 fittings.
Better, pneumatic control switch of the present invention is provided with switch periods control and regulation device, can according to the difference of head grade and composition regulate arbitrarily the discharge concentrate cycle or at any time Artificial Control discharge.
The course of work of the present invention is as follows: feed certain density ore pulp by feed pipe 8 and enter centrifugal basket 4, centrifugal basket 4 middling speed under motor 2 drives rotates, centrifugal basket 4 sidewall can penetrate back-flushing simultaneously, this back-flushing has recoil water pipe 10 joint of bottom to provide, ore pulp is under the effect of centrifugal force and water recoil strength, the gold that proportion is larger, tungsten etc. can preferentially be thrown on sidewall, be arranged on centrifugal basket 4 lateral wall and have variable extraction tube 5, the air pressure provided by air inlet pipe 9 joint of bottommost controls, the switch of the variable extraction tube 5 of FREQUENCY CONTROL of approximately every 1 minute 1 time, when open, dense media is just discharged puts concentrate hopper 6, discharged by concentrate delivery pipe 11.Remaining light substance is discharged to tail-box 7 and drains.
