Description
Technical field
The present invention relates to a kind of light section communicating pipe apparatus and method keeping mineral slurry level level in wet magnetic separator trough, belong 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 light 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
