Description
Technical field
The utility model relates to a kind of apparatus and method keeping mineral slurry level level in wet magnetic separator trough, belongs to Mineral Processing Engineering technical field.
Background technology
Wet magnetic separator includes the wet magnetic separator of ore pulp cell body and does not have the wet magnetic separator of ore pulp cell body.Effect due to the wet magnetic separator sorting having ore pulp cell body is better than the effect of the wet magnetic separator sorting not having ore pulp cell body, does not have the wet magnetic separator of ore pulp cell body to use fewer and feweri, and conventional wet magnetic separator is all the wet magnetic separator having ore pulp cell body.
The chief component of the wet magnetic separator of ore pulp cell body is had to comprise: ore pulp cell body, magnetic mineral particles sucking device (magnet or magnetic matrix), raw ore feed device, by sorption magnetic mineral particles feeding device, magnetic product discharger, non-magnetic product discharger.Away from the overfall of the restricted mineral slurry level height in ore pulp cell body upper end of feed port, overfall height is exactly the extreme higher position of mineral slurry level.Non-magnetic product discharger is the one section outlet pipe be connected with ore pulp cell body bottom, and this outlet is actually the sole outlet pipe of ore pulp cell body when normally producing.
Being sorted in ore pulp cell body in the wet magnetic separator of ore pulp cell body is had to carry out.During sorting, raw ore feeds continuously, and magnetic product departs from ore pulp cell body and discharges from the top of mineral slurry level, and non-magnetic product is discharged from the outlet being positioned at ore pulp cell body bottom.
Require due to selected district and (or) scan district's requirement, non-magnetic product outlet can not replace with overfall, and non-magnetic product outlet and ore pulp cell body junction must lower than the mineral slurry level (see figure 1)s of overfall and requirement, also away from magnetic product outlet.Just because of this, mineral slurry level level will be caused to decline when speed that raw ore feeds (volume) diminishes, impact is produced even can not output product.Improve production stability and improve production target, mineral slurry level level in wet magnetic separator trough must be kept.
For mineral slurry level level decline problem in wet magnetic separator trough, occurred at present or be expected adopt technical measures have three kinds.The first measure installs manually-operated gate (see figure 2) on non-magnetic product outlet, the second measure is mounted valve adopt various automatic control and adjustment system on non-magnetic product outlet, the third measure opens mine tailing mouth (Chinese Patent Application No. 96223415.X) at cell body close to the side of concentrate mouth, is open non-magnetic product outlet (see figure 3) in the side close to magnetic product outlet in essence.
These three kinds keep in wet magnetic separator trough in the horizontal measure of mineral slurry level, and first manually-operated gate measure is used, but also can not be not useful, because workman has little time reaction and action.Automatic valve measure is generally reliable, but, due to investment and maintenance cost high, be difficult to be used.The essence opening mine tailing mouth close to the side of concentrate mouth at cell body opens non-magnetic product outlet in the side close to magnetic product outlet, it adopts the requirement of having run counter to magnetic separator design, the selected district of magnetic product must be caused to reduce or disappear, thus cause magnetic product grade to reduce, it adopts to reduce magnetic product grade and sacrifice separating effect is cost, all should not adopt except needing the situation reducing magnetic product grade.
Mineral slurry level level in wet magnetic separator trough is kept to need better new technology.Up to now, there is not yet section and be communicated with tube method and device for keeping the report of mineral slurry level level in wet magnetic separator trough.
Summary of the invention

Described section communicating pipe, device was divided into descending and ascending portions.
Described section communicating pipe, the maximum cross-sectional area of rising part of device was the ratio of minimum mine tailing volume and maximum tailings particles floating velocity.
Device outlet entered pond, irrigation canals and ditches by directly outer for non-magnetic product or guided to other position described section communicating pipe.
When described section communicating pipe, device outlet guided to other position, section communicating pipe device outlet and outer discharge pipe (outer discharge pipe is pipeline non-magnetic product being guided to other position) junction be provided with opening.If section communicating pipe device outlet and outer discharge pipe junction there is no opening, non-magnetic product not free flow discharge, the mineral slurry level in magnetic separator will by siphonage and declining.
Above-mentioned section communicating pipe, device can adopt flexible pipe, also can adopt rigid pipe; Section communicating pipe device path can change as required.
The method of the section communicating pipe of mineral slurry level level in this maintenance wet magnetic separator trough, its concrete steps are as follows:
Step 1, according to the minimum mine tailing volume of the material added in material inlet 5 and maximum tailings particles floating velocity ratio determination section communicating pipe device the maximum cross-sectional area of rising part, guarantee that non-magnetic product Negotiation speed is greater than its floating velocity, in non-magnetic product discharge pipe, there is no particles settling, ensure that non-magnetic product all passes through;
Step 2, the section communicating pipe device of the arbitrary shape in step 1 is connected to non-magnetic product discharge pipe 1 exit position of wet magnetic separator, and section communicating pipe device outlet and ore pulp cell body 2 in the highest mineral slurry level contour;
Step 3, material is joined from material inlet 5 wet magnetic separator in step 2 ore pulp cell body 2 in carry out magnetic separation process, maintenance is stablized by the highest mineral slurry level level height in magnetic separation process in pulp tank body 2, does not feed rate by material inlet 5.
The utility model contrast prior art has following innovative point:
1. the connection tube method that application is simple and reliable keeps wet magnetic separator mineral slurry level level.
2. the discharge of non-magnetic product free flow avoids siphonic effect and causes wet magnetic separator mineral slurry level level to decline, and ensure that wet magnetic separator mineral slurry level level
3. limit the maximum basal area of rising part in non-magnetic product discharge pipe, non-magnetic product does not just have sedimentation in non-magnetic product discharge pipe, can all pass through, and ensure that being communicated with tube method reliably implements.
The utility model contrast prior art has following remarkable advantage:
1., compared with artificial valving scheme, section is communicated with tube method and device is active behavior and measure, reliably available.
2., compared with automatic valve scheme, section is communicated with tube method and device does not adopt complex technology, simply, easy enforcement, adaptivity and stability are strong, for wet magnetic separator steady production with improve production target and create condition, reliably available, small investment, maintenance cost is almost nil.
3. with non-magnetic product discharge pipe close to compared with magnetic product discharge pipe scheme, section is communicated with tube method and device does not affect separating effect, ensure that the adaptivity of production and stablize, thus ensure that separating effect, reliably available, the non-magnetic product exit position bottom ore pulp cell body can be selected as required.
