Description

Wet-type automatic dregs-discharging magnetic selecting machine

The utility model relates to a kind of wet magnetic separator that can realize automatic discharge.Be applicable to the ferromagnetic material in the industries removing slurries such as pottery, ore dressing, chemical industry, abrasive material and papermaking.Can realize working continuously, automatic discharge continuously, or according to difference require to work continuously, automatic discharge at interval.

Existing wet magnetic separator can reduce following four kinds of forms both at home and abroad at present: the first is interrupted operation, artificial scarfing cinder.It two is to be interrupted operation, automatic discharge.It three is to work continuously, and it four is that magneto is worked continuously for automatic discharge (on April 1st, 1985 applied for a patent, and the patent No. is 85200478.8), automatic discharge (applying for a patent in 1992).But above four kinds of form magnetic separators all have shortcoming and defect part separately.First kind, labor strength is big, operates heavyly, and utilization rate of equipment and installations is low, and production efficiency is low, and the magnetic separation effect is fluctuation, and human factor is big.Second kind of operation at interval, utilization rate of equipment and installations is low, and the magnetic separation effect is fluctuation, and the flusher of higher hydraulic pressure will be arranged.Though the third has overcome the shortcoming of above-mentioned two kinds of forms, its complex structure is safeguarded inconvenience, and owing to adopt suction iron pan and deslagging wheeled construction, its de-ferrous effect is subjected to inhaling the restriction of iron and deslagging contradiction.(promptly inhaling the iron interval) magnetic field degree of passing should not be too high between iron pan and the shell because inhale, otherwise (promptly arranging the iron interval) is difficult to form big magnetic field degree of passing between deslagging wheel and the suction iron pan, and be difficult to ferromagnetic material is discharged.It inhales the effect that iron pan is subjected to monolateral magnetic field pulling force in addition, and the bearing that iron pan is inhaled in supporting weares and teares easily.The 4th kind owing to adopt permanent-magnet material, and magnetic field intensity is restricted, and is difficult to satisfy the selected requirement of high-quality slurry.When the temperature of pending slurry was higher, magnetic field intensity will reduce and can not recover again simultaneously.Thereby the scope of application is restricted.

The utility model is for the shortcoming that solves above-mentioned form magnetic separator and deficiency and Development and design.The following describes its structural principle.

The purpose of this utility model is achieved in that it is made of members such as iron core, shell, magnetic conductive disk, suction iron hoop, suction iron hoop fixture, fountain head, deslagging bucket, magnet exciting coil, cooling fuel tank, cooling water tank, dragging motor, decelerator, slurry import, flow distribution plate, slurry outlet, big belt pulley, small belt pulley, V belt, connecting plate, power transmission shaft, under-chassis, support plate, bolster, support column, bearing blocks.

Constitute magnetic circuit by the interior outer baffle in iron core, shell, magnetic conductive disk, suction iron hoop and the suction iron hoop fixture.When magnet exciting coil passes to DC current, between the interior outer baffle of inhaling the iron hoop fixture, promptly form the high-intensity magnetic field zone, because the effect of the special construction of suction iron hoop in this zone, make the high magnetic field area that has formed high degree of passing in the space of the suction iron hoop by slurry.Slurry by the time wherein ferromagnetic material be attracted to and inhale on the iron hoop.

On the same position on magnetic conductive disk and the two circumference of shell, all be processed with a sector notch, the size of its sector notch has only faint magnetic field can make the section (to call this section in the following text is the deslagging section, and all the other sections of inhaling iron hoop are for inhaling the iron section) of inhaling iron hoop and being in this breach.Above the deslagging section of inhaling iron hoop a fountain head is set, it can spray to the running water of certain hydraulic pressure and flow the suction iron hoop, the ferromagnetic material of inhaling in the iron hoop is developed, outside the deslagging bucket discharge machine by the setting of deslagging section below.The utility model has just been realized the purpose of automatic discharge like this.

Operation process of the present utility model is achieved in that pending slurry flows into from the slurry import, make it evenly flow into the suction iron section of inhaling iron hoop by flow distribution plate, ferromagnetic material in the slurry is attracted to be inhaled on the iron hoop, and slurry all flows down, and flows out from slurry outlet again.Inhale iron hoop dragging motor by the drive of decelerator and transmission device under rotation at a slow speed.Be adsorbed on ferromagnetic material on the iron hoop and inhaled iron hoop and take the deslagging section to, the running water that is sprayed by fountain head develops again, outside deslagging bucket discharge machine, moves in circles like this and has just realized working continuously, continuously automatic discharge.In pending slurry, contain ferromagnetic material more after a little while,, can it be sprayed water at interval, so just realized working continuously, at interval automatic discharge by the water spraying time of control fountain head for using water wisely.The water supply pipe of the desirable own certain hydraulic pressure in the water source of fountain head.Supply water as the too low micro pump that adopts of user's tap water hydraulic, or head-tank is set.
