Abstract

The utility model discloses a separating screen which comprises a big end up screen body (3), wherein a material feeding pipe (1) is introduced into a buffer slot (2) arranged on the upper part; a pulp distributer (4) is arranged below the slot; the distributer is arranged in an overflow slot (10); an overflow weir (6) is arranged in front of the overflow slot; two layers of screen sheets (7 and 8) are arranged below the overflow weir; the two layers of screen sheets are downward inclined from front to back; the front end of each screen sheet is provided with a flushing pipe (8); the pipes are evenly provided with water outlets (11); and a material discharging pulp pipe (5) is connected below the screen body. In the device, a wide-width overflow slot is used for feeding, the screening area is effectively increased, and the separation efficiency is improved. The screen body is welded and fixed, and the traditional vibrating inclined separation is replaced by fixed horizontal separation so as to realize static separation and reduce abrasion. The screen cloth breakage rate is reduced by 93.75% compared with that of the traditional screen cloth of the linear vibrating screen. The screen sheets can be conveniently replaced, primary screening is replaced by secondary screening, and the screening efficiency is improved.

Description

Bolter

Technical field the utility model relates to a kind of device that ore pulp and other solids leave of in the mine produces, realizing, is the bolter that can realize that ore pulp and wood chip effectively separate specifically.

Background technology is present, during the mine produces especially all sliming cyanidation carry in the gold mine of gold, debris removal is a step very crucial in the whole technology; Known debris removal mode is spiral debris removal sieve and linear vibrating screen; These two kinds of debris removal modes all need power, and the screen cloth quick abrasion is changed frequent; Operating difficulties, the debris removal effect is undesirable.

The purpose of summary of the invention the utility model is to provide a kind of bolter, and it does not need power, realizes the static separation of ore pulp and wood chip, has greatly reduced the screen cloth wearing and tearing, and it is simple and quick that screen cloth is changed.

The technical scheme of the utility model is following:

This device has up big and down small sieve nest, and the supplied materials pipe feeds the dashpot that is located at top, and this groove is pulp distributer down; This distributor places in the overflow launder; Establish downflow weir before the overflow launder, divide into the two layer screen sheet at downflow weir, above-mentioned two layer screen sheet is extremely preceding downward-sloping by the back; Front end at each sieve sheet is established wash tub pipe, and this pipe is uniformly distributed with apopore; Platoon material ore pulp pipe under sieve nest.

The inclination angle of two above-mentioned sieve sheets is 8～15 degree, two-layer draw-in groove about the welding on the sieve nest, gravity flow screen sheet.

Two above-mentioned sieve sheets are made up of wooden frame and stainless (steel) wire compass screen surface, and upper strata screen cloth mesh is 0.6mm, and the lower screen mesh is 0.4mm.

The advantage of the utility model is: 1, this device is used the wide cut overflow launder instead and is given the ore deposit, evenly gives ore deposit to whole compass screen surface with tradition by supplying the ore deposit case to change overflow launder into to the ore deposit, has effectively increased sieving area, has improved separative efficiency.2, weld fixedly sieve nest, become traditional vibration and tilt to be separated into the fixing horizontal separation, realize static separation, reduce wear, the sieve breakage rate has reduced 93.75% than the linear vibrating screen screen cloth.The sieve sheet is detachable wooden frame and stainless (steel) wire compass screen surface, is convenient for changing; Cover surface is increased, and thereunder set up one deck screen cloth again, change once screening is regrading, has improved screening efficiency, and ore pulp flows unimpeded.3, change the screen cloth mesh of setting up into 0.4mm by original 0.6mm, tiny wood chip or resin lived in interception effectively, strengthened debris removal and recovering effect.4, strengthened towards Xian Lidu, set up towards Xian Shuiguan at the end of each layer sieve, water pipe evenly is covered with aperture; Let and evenly help separating of ore pulp and wood chip or thin resin dispersedly towards Xian Shui; Reduce impulsive force, alleviate the sieve pore blockade phenomenon, reduce the damaged condition of screen cloth compass screen surface.

Description of drawings Fig. 1 is the utility model embodiment front view;

Fig. 2 is that the A-A of Fig. 1 is to view;

Fig. 3 is the utility model embodiment vertical view.

1 ore pulp supplied materials pipe among the figure, 2 ore pulp dashpots, 3 sieve nests, 4 pulp distributers, 5 discharge ore pulp pipe, 6 ore pulp downflow weirs, 7 ground floors sieve sheet, 8 towards Xian Shuiguan, 9 second layers sieve sheet, 10 overflow launders, 11 apopores.

The specific embodiment is described further the utility model below in conjunction with accompanying drawing.

Can see that by Fig. 1-3 in separating sieve nest 3, ore pulp supplied materials pipe 1 inserts ore pulp dashpot 2; Flow of slurry drops on the pulp distributer 4 through ore pulp dashpot bottom, and pulp distributer 4 horizontal weldings are connected on the latter half that separates sieve nest 3, and this distributor places in the overflow launder 10; Establish downflow weir 6 before this groove; Flow of slurry is carried out secondary uniform distribution to ground floor sieve sheet 7 through ore pulp downflow weir 6 after evenly separating through pulp distributer 4, in the wood chip income wood chip container, flow of slurry gets into 9 secondary separations of second layer sieve sheet on the sieve sheet; In the secondary separation wood chip income wood chip container; All establish towards Xian Shuiguan 8 outer end of two layer screen sheet, and this pipe has the apopore 11 that is uniformly distributed with, and the product under the secondary sieve gets into and goes to expect ore pulp pipe 5.Low before the height behind the two layer screen sheet installation site, form inclination angle 10 degree.The two layer screen sheet is fixedly stainless (steel) wire structure of independent detachable wooden frame, and upper strata screen cloth mesh is 0.6mm, and lower screen network selection mesh is 0.4mm.
