Abstract
The utility model belongs to heavy media coal separation and utilizes magnetic separator to reclaim the improvement of magnetite powder feed arrangement structure, particularly a kind of heavy media coal separation utilizes magnetic separator to reclaim the feeding regulating device of magnetite powder, include hopper and be connected to sorting groove by mozzle, coordinate in sorting groove and drums for magnetic separation machine is installed, the sorting groove bottom being positioned at feed box side is connected to concentrate hopper, the bottom of the opposite side of sorting groove arranges tail-box, on the bottom surface of feed box and between the sidewall of concentrate hopper, be connected to communicating pipe, communicating pipe is installed with electric hydraulic valve door.It is rational in infrastructure, can stop the race of magnetic separator feed box and emit rare medium, save magnetite powder, reduce cleaning works amount, keep working environment clean.
Description
Technical field
The utility model belongs to heavy media coal separation and utilizes the improvement, particularly a kind of heavy media coal separation of magnetic separator recovery magnetite powder feed arrangement structure to utilize magnetic separator to reclaim the feeding regulating device of magnetite powder.
Background technology
Hm coal preparation plant utilizes permanent-magnet roller type counter-current separator to reclaim magnetite powder in rare medium.Joining Technology is that the rare medium pump in rare medium bucket is pumped into magnetic separator by Pulp pump, and after magnetic separator magnetic separation, concentrate enters qualified medium bucket, and mine tailing enters slime water system.Magnetic separator feed box is open type, and rare medium, after feed box buffering, directly enters magnetic separator magnetic separation.During normal production; magnetic separator overcurrent is normal, feed box not overflow, but when (or the material dilution in rare medium bucket being beaten totally after shutdown on duty after accidental shutdown; during start in second day); when starting shooting again, due to coal slime and magnetite powder precipitation, occur that Pulp pump opens little not material loading (VFC); when Pulp pump is opened large; magnetic separator feed box runs and emits rare medium, contaminated environment, and cleaning works amount strengthens.
Utility model content
The purpose of this utility model is to provide a kind of heavy media coal separation to utilize magnetic separator to reclaim the feeding regulating device of magnetite powder, it is rational in infrastructure, can stop the race of magnetic separator feed box and emit rare medium, save magnetite powder, reduce cleaning works amount, keep working environment clean.
The purpose of this utility model is achieved in that a kind of heavy media coal separation utilizes magnetic separator to reclaim the feeding regulating device of magnetite powder, include hopper and be connected to sorting groove by mozzle, coordinate in sorting groove and drums for magnetic separation machine is installed, the sorting groove bottom being positioned at feed box side is connected to concentrate hopper, the bottom of the opposite side of sorting groove arranges tail-box, on the bottom surface of feed box and between the sidewall of concentrate hopper, be connected to communicating pipe, communicating pipe is installed with electric hydraulic valve door.
The utility model is connected a DN250mm communicating pipe with between magnetic separator concentrate pipe bottom magnetic separator feed box, middle installation DN250 electric hydraulic valve door; When starting shooting again when accidental shutdown, electric hydraulic valve door being opened, by rare for part medium shunt to qualified medium bucket, reducing into magnetic separator flow, ensure magnetic separator not overflow, when pan feeding is normal by the time, slowly again electric hydraulic valve door is closed.No matter in which kind of state start shooting, enable by-passing valve discharging, magnetic separator feed box does not occur running overflow, Be very effective again; Save magnetite powder, monthly emit according to 5 races, each loss magnetite powder 2 tons, magnetite powder per ton 1000 yuan calculating, annual saving 120,000 yuan.
The utility model is rational in infrastructure, has stopped the race of magnetic separator feed box and has emitted rare medium, saved magnetite powder, decreased cleaning works amount, decrease environmental pollution, maintain working environment clean.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model will be further described, and Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
A kind of heavy media coal separation utilizes magnetic separator to reclaim the feeding regulating device of magnetite powder, as shown in Figure 1, include hopper 1 and be connected to sorting groove 2 by mozzle, coordinate in sorting groove 2 and drums for magnetic separation machine 3 is installed, sorting groove 2 bottom being positioned at feed box 1 side is connected to concentrate hopper 4, the bottom of the opposite side of sorting groove 2 arranges tail-box 5, is connected to communicating pipe 6, communicating pipe 6 is installed with electric hydraulic valve door 7 on the bottom surface of feed box 1 and between the sidewall of concentrate hopper 4.The diameter of communicating pipe 6 is 250 ㎜.
