Discharging system of coal mill

Abstract

The invention discloses a discharging system of a coal mill. The discharging system comprises a storage box, a conveying mechanism, a discharging mechanism and a control device, wherein, the conveying mechanism comprises a conveying pipe and a conveyor used for conveying materials, and the conveyor is located in the conveying pipe; the storage box is connected with the conveying pipe through a connecting pipeline, the conveying pipe is connected with the discharging mechanism, and a regulation and control gate is arranged on the connecting pipeline; the control device comprises a detector used for detecting the materials and a controller capable of operating opening and closing of the regulation and control gate; and the detector is installed in the storage box and is in communication connection with the controller, and the controller is in communication connection with the regulation and control gate. The discharging system of the coal mill can automatically discharge the materials and convey the materials to the discharging mechanism, so that the automation degree is improved, and the use of manpower is reduced; and the conveyor is located in the conveying pipe, so that the sealing performance is improved, the spreading of dust is reduced, the working environment is improved, and the body health of workers is guaranteed.

Description

technical field [0001] The invention relates to the field of power generation equipment, in particular to a coal mill discharge system. Background technique [0002] In recent years, medium-speed coal mills have low initial investment due to their adaptability to coal types. The advantages of low power consumption in operation are being applied by more and more vitality power plants. Pebble coal is an ungrindable by-product discharged from the medium-speed coal mill during its operation. It mainly comes from coal gangue, ore and some hard-to-grind coals mixed with coal types. During operation, the discharge temperature of pebble coal is about 160°C, and the amount of pebble coal is closely related to coal source and operating conditions. Therefore, whether the pebble coal can be discharged in time will play a vital role in the normal operation of the coal mill. [0003] At present, the pebble coal is usually transported manually, and the pebble coal is directly discharged...
