13, equipment arranges lighting device, is convenient to observe each position when machine runs.
14, each automatic heating devices heat heating-up temperature is stablized, and temperature adjustment is flexible, improves sorting output and efficiency, expands the scope of application of this machine.
15, equipment has shaft type feeding and vibration slide type feeding to combine pattern, because of phase mutual adhesive between thinner material, as only material adhesion can be made with shaft type feeding, be unfavorable for sorting, vibration slide plate can carry out vibration and breaks up out inter-adhesive compared with fine material, the even waterfall shape of material can be made to be the uninterrupted feeding of transfer roller, and the angle heating slide plate can adjust according to the granularity of material.In machine, transfer roller and vibration heating slide plate are because there being heater, and make the temperature in machine higher, vibration heating slide plate by spring supporting support, and is connected with frame, by support two ends extractor outer upper end vibrating motor support.The two stands of drawing is each fixes a vibrating motor for slide plate provides vibration source.Avoid the too high vibrating motor that makes of Yin Wendu to damage, thus improve the efficiency of separation and purity.
16, each roll surface is made up of thicker hard chrome plating and stainless steel, each hair roller brush is that wire is made, during normal work, roll surface temperature is about about 70 DEG C, and hair roller brush rotating speed is greater than transfer roller, more be conducive to producing when both transfer roller and hair roller brush run rubbing thus heating up, greatly reduce electrically heated energy consumption.
17, this type of electrostatic separator overcome since the dawn of human civilization electrostatic separator because of in storehouse amount large, and the technical barrier of sorting again cannot be carried out, and middle storehouse cycle stock directly carries out sorting again decreases the energy consumption again heated.
18, the vibration heating sliding plate of the drawing-in device lower end of equipment solves in the world slide plate heating for a long time and vibrates the technology combined (is about sorting material granularity is reduced to 300 orders greatly, comparatively fine material also can be scatter mutually, and material becomes waterfall shape evenly to deliver to transfer roller).
Main feature: this type solves the little and solution of two row six roller electrostatic separator sorting material unification since the dawn of human civilization, the scope of application must not adjust sorting quality requirement simultaneously shortcoming to sorting material front storehouse material and tail storehouse material.Can simultaneously to front storehouse material cleaning and Purification and tail storehouse material cleaning and Purification when this type of machine runs, because each adjustment plate adjustment angle is very large, after adjusting each adjustment plate to front storehouse material during sorting and after storehouse material carry out the double action of cleaning and Purification, all kinds of sorting material is carried out concentrating and discharges.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.
