Abstract
The invention relates to a no-vibration underwater drum screen used for industrial and mining enterprises, which comprises a drum screen formed by a drum and screen pieces, a feeding opening, a central shaft, a motor and a speed reducer, wherein a water tank is arranged at the bottom of the drum screen, and an overflow port is arranged at the side part of the water tank; the feeding opening is provided with branch feeding openings at both sides of the central shaft; a flow guiding blade and a flow guiding plate are arranged at the discharging opening of the drum screen; a screw discharging machine is arranged at the bottom of the water tank; and an external water trough is arranged at the lower part of the overflow port and a filter sieve is arranged at the upper part of the external water trough. The screen pieces are made of white steel plates or nylon and are arranged in linear intercrossed shapes or reversed V shapes, and the aperture of the screen pieces is 0.1-0.2 mm. The invention has the advantages of hard blockage of the screen, high screening efficiency and long service life; the drum screen works underwater; and the problems of high density and easy wear of the nylon screen pieces of the vibrating screen are effectively solved.
Description
Technical field
The present invention relates to a kind of no-vibration underwater drum screen that is used for industrial and mining enterprises.
Background technology
In the prior art, the device that industrial and mining enterprises are widely used to be used for sieving material mostly is high frequency shale shaker, and the shortcoming of its existence is: material stops up screen cloth easily, and screen life-span is low, is not suitable for the usefulness of relatively large fluid foods separation.At present domestic two kinds of high frequency shale shakers that generally adopt such as nylon mesh sheet plugging rate are 30%-55%, and white steel mesh grid screening percentage is low, has only seven to ten days service life.More than two kinds of high frequency shale shakers have shortcomings such as floor space is big, the dither power consumption is big.
The sieve sheet of rotary screen commonly used all is the soft sieve sheet of woven mesh, the screening large granular materials, and be dry screen, easy to wear, service life is short.
Summary of the invention
The purpose of this invention is to provide that a kind of screen cloth is not easy to stop up, the no-vibration underwater drum screen of sub-sieve rate height, long service life, this rotary screen is worked under water, has solved effectively that the close sieve of vibratory sieve nylon mesh sheet is high, sieve sheet problem easy to wear.
For achieving the above object, technical scheme of the present invention is described below:
No-vibration underwater drum screen comprises rotary screen, charging aperture, central shaft, motor, the reductor be made up of cylinder and sieve sheet, and the rotary screen bottom is provided with water tank.
Be provided with overfall at the water tank sidepiece; Described charging aperture is told the branch road charging aperture that is arranged at the central shaft both sides; Discharging opening place at rotary screen is provided with guide vane and deflector; Be provided with spiral discharging machine at water tank bottom; The overfall bottom is provided with outside tank, and outside tank top is provided with sieves.The sieve sheet is made with white steel plate or nylon, and it is shaped as in-line cross arrangement or circular array, and its aperture is 0.1-0.2mm.
Compared with prior art, the invention has the beneficial effects as follows:
1) because cylinder and sieve sheet are arranged in the water, makes that sieve sheet plugging rate under the tension force effect of water is zero substantially, sub-sieve rate height.
2) material is washed in the sub-sieve process, and owing to the proportion of material in water tank and foreign material is different, this device carries out AUTOMATIC ZONING, makes the mineral of extraction purer, improves more than 2 points of grade of fine ore.
3) because screening is to carry out under water, the twice program of conventional screen selecting technology is united two into one, traditional screening mode is at first to remove floating thing by screening, and this device can make floating things such as wood chip, grass bits automatically along with current spill in the outside tank.
4) compare with traditional high frequency shale shaker, the present invention have take up room little, output is high, low power consumption and other advantages.
5) the present invention adopts friction triage techniques under water, has prolonged the service life of screen cloth greatly.
