Microwave drying and screening integrated machine

Abstract

The invention belongs to the technical field of microwave drying and screening equipment, and discloses a microwave drying and screening integrated machine which comprises a screening box, a base, a microwave radiating body supporting rod, a vibration motor, a microwave suppressor, a screening plate, a microwave radiating body and the like. The bottom of the screening box is arranged on the base through an elastic body, the top of the screening box is provided with a feed inlet and an exhaust pipe, the bottom end of the microwave radiating body supporting rod is arranged on the base, the microwave radiating body supporting rod hoists the microwave radiating body to the upper portion of an inner cavity of the screening box through an avoiding hole, the vibration motor is arranged on the topof the screening box through a fastener, the screening plate is arranged in the middle of the inner cavity of the screening box through a fastener, a cross beam is fixed to the upper portion of the inner cavity of the screening box through a fixing flange, the microwave suppressor is arranged on the inner wall of the screening box, a screen underflow conveying belt penetrates through the middle of the screening box, and an oversize material conveying belt penetrates through the discharge side of the screening box. The defects that wet materials are likely to block holes in the screening process, the screening efficiency is low, and the product quality is low can be effectively overcome.

Description

technical field [0001] The invention belongs to the technical field of microwave drying and screening equipment, and specifically refers to a microwave drying and screening integrated machine. Background technique [0002] Vibrating screening equipment is widely used in many industrial fields such as mines, mainly responsible for the classification of materials and other tasks. In the field of coal preparation, when the vibrating screen handles wet fine-grained coal, the problem of material plugging often occurs, resulting in low screening efficiency and difficulty in the normal screening process, which in turn affects the entire coal preparation process. [0003] Microwave drying is a new type of drying method. During the drying process, the microwave energy directly acts on the medium molecules and converts the microwave energy into heat energy. Because microwave is penetrating, it can heat the inside and outside of the medium at the same time without heat conduction, so...
