Parallel double-roll heating internal circulation electric separator

Abstract

The invention discloses a parallel double-roller heating internal circulating electrostatic separator, which comprises orderly arranged components of, from top to bottom: a material chamber, a heating system, a feeding system, sliding plates, electrostatic separator rollers, subordinate material chambers, a discharging system, a circulating system, and a material filling system. The electrostatic separator is provided with two parallel sliding plates. The upper ends of the sliding plates are connected to the subordinate material chamber feeding system, and the lower ends of the sliding plates are connected to corresponding electrostatic separator rollers. One side of the electrostatic separator rollers is provided with high voltage composite electrodes. Material separating chambers comprise a front chamber, a middle chamber and a rear chamber. Separated materials discharged from front chamber outlets and a rear chamber outlet are respectively collected. Middle circulating discharging outlets are orderly connected to a middle chamber concentrated outlet device and an elevating filling device. An upper outlet of the elevating filling device is connected to the material chamber. The electrostatic separator provided by the invention is advantaged in that: the productivity of the electrostatic separator is two times that of similar type single-roller electrostatic separators; and circulated re-separation can be carried out in the separator, the circulated material can be directly re-separated, such that energy consumption is reduced, and efficiency is improved. According to the invention, shaft feeding and vibration sliding plate feeding are combined, and a heating system is attached, such that the separation scope is broadened.

Description

technical field [0001] The invention relates to the technical field of separation and purification of different mixed solid materials, in particular to a side-by-side double-roller heating internal circulation electric separator for electric separation and separation according to the electrical difference of different materials. Background technique [0002] The electric separator is the main equipment used for material separation in the prior art. However, in the prior art, there are the following problems: 1. Single-roller single-row electric separators are generally used, so that there is a waste of energy and also affects work efficiency; In this way, the material needs to be reheated after cooling, which causes energy waste and reduces work efficiency. 3. The feeding system of the traditional electric separator, spline shaft feeding, vibrating slide plate and heating cannot be combined, thus reducing the separation efficiency and greatly reducing the range of separatio...
