Abstract
The utility model relates to a vibrationless underwater drum screen used in industrial and mining enterprises. The drum screen comprises a drum screen consisting of a drum and sieves, a feed port, a central axis, an electric motor and a decelerator, wherein the bottom of the drum screen is provided with a water tank, and a side of the water tank is provided with an overflow port; the feed port is divided into branch feed ports arranged on both sides of the central axis; a discharge port of the drum screen is provided with a guide vane and a guide plate; the bottom of the water tank is provided with a spiral discharging machine; the lower part of the overflow port is provided with an outer water channel; and the upper part of the outer water channel is provided with a filter sieve. The sieves are made of white steel plate or nylon, and are in in-line crossed arrangement or lambdoid arrangement; moreover, the aperture of the sieves is between 0.1 and 0.2 millimeter. The vibrationless underwater drum screen has the advantages that the drum screen is not easy to block up and has high screening rate and long service life; and the drum screen operates under water and effectively solves the problems that nylon sieves of a vibrating screen have high density and are easy to wear out.
Description
Technical field
The utility model 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.
The utility model content
The purpose of this utility model provides 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, and 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, the technical solution of the utility model 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 beneficial effects of the utility model are:
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 utlity model has take up room little, output is high, low power consumption and other advantages.
5) the utility model adopts friction triage techniques under water, has prolonged the service life of screen cloth greatly.
