Abstract

The present invention relates to a separation device for fine-particle heavy minerals such as stannum, tungsten, etc., which can effectively recover the heavy minerals with the granularity less than 37 micrometers in slurry. The utility model is mainly characterized in that riffles of which the transverse sections are similarly in a streamline shape are arranged on a machine surface; bottoms of grooves among the riffles are in a cambered shape; riffles with different width and depth are arranged except for concentration parts; surfaces of the grooves and partial concentration parts are provided with small shallow grooves; the gradients of the bottoms of the grooves and the small shallow grooves are both small. Because the present invention has high efficiency for recovering the fine-particle heavy minerals, the present invention can replace centrifugal separators, belt sliding chutes, etc., reduce separation work and equipment dosage and reduce the consumption of water, electricity and human power and production cost.

Description

Fine-mud shaker

The present invention relates to the fine-mud shaker of fine-grained heavy minerals such as a kind of separating tungsten, tin, gold.The various slimers that are used for fine-grained heavy minerals such as separating tungsten, tin, gold in the existing industrial production, all can only effectively reclaim granularity and (press quartzy proportion greater than 37 microns, the elutriation hondrometer) heavy mineral, Chinese patent CN86206078U, it is 74 to 37 microns fine-grained heavy minerals that cutting shaking table bed surface only effectively reclaims grade, and can not effectively reclaim the fine-grained heavy minerals less than 37 microns.The prior art recovery is very low less than the efficient of 37 microns fine-grained heavy minerals, therefore, for reclaiming fine-grained heavy minerals less than 37 microns, general centrifugal ore separator-belt chute-cutting the shaking table that adopts is formed, roughly select, selected and the repeatedly complicated technology of sorting operation such as scan, the ore-dressing practice that has reaches nearly ten times, so that the main equipment and the auxiliary equipment that need are many, water,, manually, spare parts consumption and production cost height, maintenance load is big, be difficult to management, the technical-economic index instability, and be downward trend day by day, add that the washability difference of sorted materials and valuable mineral content do not descend, make economic benefit very poor, even loss.

The objective of the invention is to overcome the above-mentioned shortcoming of prior art, and a kind of fine-mud shaker that can effectively reclaim fine-grained heavy minerals such as tungsten less than 37 microns, tin, gold is provided.

The objective of the invention is to reach by following approach: the present invention mainly by bed surface, the head of a bed, to the even plate that divides in ore deposit, the even parts such as device, sliding bearing, slope adjusting device, spring and tension lines that divide of feedwater are formed.The groove bottom of trench of junction is designed to streamlined and arc respectively between riffling cross section on the bed surface and riffling and the riffling.The groove width of roughly selecting the district and scanning the district be the after backwashing district the groove width 1-6 doubly.Trench depth between the riffling is 0.05-0.5% by the groove bottom gradient, vertically disappears by being deep to shallow back along bed surface, and it is the little shallow ridges of 0.02-0.8% that there is the gradient in groove surface between riffling and selected district.Because little stroke, high jig frequency are adopted in the motion of above-mentioned bed surface structure and bed surface, when making the groove of flow of slurry between riffling, its streamline is bordering on parallel, eddy current is very little, and the stream film is thin, and flow velocity is little, stream interface is steadily calm, is bordering on laminar flow, makes that fine-grained heavy minerals is can be on bed surface fine to sink and be recovered.

Prior art is compared, and the present invention has following advantage:

1, the rate of recovery of particulate heavy metal is high 1～2 times, can increase by 1～2.5 times of the output value.

2, can simplify and sort flow process, the rarest centrifugal ore separator of original flow process is roughly selected, selected and the cutting shaking table of belt chute such as scans at three subjobs, what have reaches more than ten subjobs, only need one-stop operation after adopting the present invention, increase centrifugal ore separator at most and roughly select or select chats again one time with the present invention.

3, can reduce main equipment, auxiliary equipment, electricity, artificial and raw material, spare parts consumption amount more than 1/3, can fall water consumption 2/3 with, last production cost can reduce more than 40%.

But several prods such as 4 output concentrate, rich chats and poor chats also can only produce a kind of product (rich chats).

5, can effectively reclaim granularity less than 37 microns fine-grained heavy minerals, when producing rich chats, the grain-level recovery of 37-19 micron, 19-10 micron, 10-5 micron particulate cassiterite is higher 1.4 times than prior art respectively, more than 3 times and 10 times.

6, Operation and maintenance workload greatly reduces, convenient management.

7, production and technical indication is stable.

8, also can replace brick wall that small towns and individual enterprise use, put preparation equipments such as groove and garden shape groove, production efficiency is increased substantially, operator's intensity reduces greatly.

The present invention describes in detail below with reference to the embodiment in the accompanying drawing: as shown in Figures 1 and 2, the present invention is mainly by bed surface (1), the head of a bed (2), to the even plate (3) that divides in ore deposit, the even device (4) that divides of feedwater, sliding bearing (5), slope adjusting device (6), spring (7) and tension lines parts such as (8) are formed, as shown in Figure 3, groove section between riffling section on the bed surface (1) and bed and the riffling is respectively streamlined and arc, as shown in Figure 2, the width of the riffling of bed surface (1) and highly all inequality, the trench depth between the riffling vertically disappears after being deep to line along bed surface by the gradient of bottom of trench; Roughly selecting the groove width of distinguishing and scan the district is that after backwashing district groove width is 1-6 times.The gradient of groove bottom is 0.05-0.5% as shown in Figure 4, shown in accompanying drawing 6 and accompanying drawing 5, on groove surface and the selected district of part little shallow ridges is arranged, and the gradient of little shallow trench ditch bottom is 0.02-0.8%.

Under the situation that yellow Maoshan Mountain selecting and purchasing factory of Yunnan Tin Industrial Corp. mud miner Duan Zaijie ore deposit amount descends significantly, loss appears in the complicated technology of original seven subjobs, (centrifugal ore separator is roughly selected to be reduced to three subjobs, belt chute is selected, and the cutting shaking table is scanned and selected mine tailing) after, the loss situation reversed, after the trial edition invention, more be reduced to one-stop operation, received following good test effect, also can make than being reduced to three subjob technologies:

Cost of equipment, power consumption and manually respectively reduce more than 1/3;

Water consumption reduces more than 2/3;

Production cost reduces by 40%;

When producing rich chats, under the high 0.4 times situation of rich ore rate, the rate of recovery improves 1 times, and the output value increases by 1.2 times, produces rich chats as former flow process, and the present invention produces concentrate, and the output value increases by 2.3 times.
