Abstract
The utility model discloses an underflow anti-blocking device of a thickener. A cylindrical discharge well is mounted at the bottom of a cone hopper of the thickener, a feed port and a discharge port are respectively formed on the side wall of the discharge well, the discharge port is communicated with a feed pipe of a conveying pump, the feed port is communicated with a discharge pipe of a circulating pump, and the feed pipe of the circulating pump is communicated with a material supply pipe of the thickener; and the requirements are as follows: the discharge port is 200-500mm higher than the feed port, the feed port is positioned at the bottom of the side wall of the discharge well, and the axial line of the feed port is tangential to the side wall of the discharge well. Well thickened ore pulp is discharged through the discharge pipe of the conveying pump; the circulating pump can draw out the small quantity of the ore pump from the material supply pipe 5 of the thickener as a circulating medium for circulation under low-energy consumption conditions, material is supplied into the discharge well along the tangential direction during circulating discharge, the ore pulp in the discharge well can be kept in a state of moving always, and the blockage of an underflow discharge port of the thickener can be further prevented.
Description
Technical field
The utility model relates to the solid-liquid separating equipment in the mineral processing, relates in particular to concentrator.
Background technology
Concentrator is one of important equipment of mineral processing industry, and cardinal principle is widely used in ore dressing plant Separation of Solid and Liquid operation based on the gravitational settling effect.A lot of in the concentrator kind of using at present, mainly contain round pond type concentrator, lamella thickener and Hhigh-efficient thickener etc.From structure certain similitude is arranged, general top is cylinder, and the bottom is connected with the cone of certain cone angle.Ore pulp is called underflow from the material of bottom discharging after dense, and the material that overflows from top is called overflow.Overflow is open discharging, and is generally all comparatively smooth and easy.Underflow will guarantee certain concentration of emission usually, and when the concentration of emission of needs was higher, material may stop up the underflow floss hole, cause the underflow can not continuous blow-down, particularly in recent years, the underflow density that requires along with concentrating process is more and more higher, and this problem is more outstanding.
Summary of the invention
The purpose of this utility model is in order to prevent that thickener underflow floss hole material from stopping up, and designs a kind of thickener underflow anti-block apparatus; This device can make the slurry of concentrator bottom be in state of disturbance, prevents the deposition of material, thereby the assurance underflow can be discharged smoothly.
Purpose of the present utility model is implemented by the following technical programs:
A kind of thickener underflow anti-block apparatus, it is characterized in that, it is in the bottom of concentrator awl bucket a cylindrical shape discharge well to be installed, be respectively equipped with charging aperture and discharging opening on the sidewall of discharge well, discharging opening is communicated with the delivery pump feed pipe, charging aperture is communicated with the circulating pump discharge nozzle, and the feed pipe of circulating pump is communicated with the feed pipe of concentrator; Require: discharging opening is higher than charging aperture 200-500mm, and charging aperture is positioned at discharge well sidewall bottom, and the axis of charging aperture and discharge well sidewall are tangent.
The diameter of above-mentioned discharge well is preferably 1-3 rice, and ratio of height to diameter is preferably 0.5-1.
Below by operation principle of the present utility model its advantage is described, dense good ore pulp is discharged through the drainage conduit of delivery pump; Circulating pump extracts a small amount of ore pulp from concentrator feed pipe 5 and circulates as circulatory mediator under the condition of low energy consumption, material tangentially feeds the discharge well when the circulation discharge, keep the interior ore pulp of discharge well to be in the state of motion constantly, prevented the obstruction of thickener underflow floss hole.
Description of drawings
Fig. 1 is front view of the present utility model, there is shown the deployment scenarios of the utility model anti-block apparatus on concentrator;
Fig. 2 is the A-A view of Fig. 1.
Among the figure: 1-concentrator, 2-discharge well, 3-delivery pump, 4-circulating pump, 5-feed pipe, 6-discharging opening, 7-charging aperture.
The specific embodiment
As illustrated in fig. 1 and 2, thickener underflow anti-block apparatus of the present utility model is in the bottom of concentrator 1 awl bucket a cylindrical shape discharge well 2 to be installed; The left side wall of discharge well 2 is provided with discharging opening 6, and discharging opening 6 is communicated with delivery pump 3 feed pipes; The right side wall bottom of discharge well 2 is provided with charging aperture 7, and charging aperture 7 is communicated with circulating pump 4 discharge nozzles, and the feed pipe of circulating pump 4 is communicated with the feed pipe 5 of concentrator 1; The height that requires discharging opening 6 to be higher than charging aperture 7 is that 200-500mm(sees Fig. 1), and the axis of charging aperture 7 and the tangent (see figure 2) of discharge well 2 sidewalls.
The diameter of above-mentioned discharge well 2 is preferably 1-3 rice, and ratio of height to diameter is preferably 0.5-1.
Embodiment: certain iron ore beneficiating factory, need carry out dense processing to comprehensive mine tailing, in order to carry out the down-hole consolidated fill, the concentration that feeds of concentrator is 30%, requires underflow density to reach more than 68%.According to flow and the sinking speed of mill tailings, it is that 10m, cylinder high are 45 ° two of concentrators for 8m, cone angle that diameter is selected in design for use.Awl bucket adopts steel construction piece, and the circular hole that to open a diameter in the bottom of awl bucket be 2m is rigidly connected with discharge well 2, and discharge well 2 is the cylinder of diameter 2m, high 2m, and discharge well 2 bottoms are supported with steelframe.The both sides of discharge well 2 are installed circulating pump 4 and delivery pump 3 respectively, circulating pump 4 extracts a small amount of low concentration ore pulp as circulatory mediator from concentrator feed pipe 5, feed discharge well 2 bottommosts with tangential way and form eddy flow, the feed pipe of delivery pump 3 is positioned at 200mm place, circulating pump 4 discharge nozzles top.
After equipment comes into operation, the underflow density of concentrator can reach 70%, and underflow can continous-stable discharge, effectively solved obstruction that concentrator causes because of bottom high concentration settling ore pulp and the problem of underflow discharging difficulty, produce a desired effect.
