Air-vibrating type jet-boosted discharging device

Abstract

The invention relates to an air-vibrating type jet-boosted discharging device. The device comprises multiple stages of jet material conveying sections and jet pulse generators; a feed coal inlet section is arranged at the top of the first-stage jet material conveying section, and a feed coal outlet section is arranged at the bottom of the last-stage jet material conveying section; and each stage of jet material conveying section is provided with a jet pulse generator, the jet pulse generator generates a pulse airflow instantaneously through programmed control, then an airflow shovel is formed on the bottom surface of each stage of feed-coal conveying section, so that wet coal materials adhered to the bottom surface of each stage of conveying section are completely shoveled and discharged from a feed coal outlet. The device disclosed by the invention has the advantages that: by using the device, the smooth conveying of materials under airtight conditions can be realized, and an effect of no vibration and shock on equipment can be achieved in the process of conveying high-viscosity and high-moisture-content materials, thereby ensuring the operating reliability of conveying equipment.

Description

technical field [0001] The invention relates to a gas-vibration blowing booster feeding device, which is mainly used in a coal humidity control process system where the coal material with high moisture content and high viscosity needs to be transported without a power belt inclination angle. Background technique [0002] In the coking coal humidity control (drying) process system, there is a raw material wet coal feeding device, which can make coking coal with high moisture content (up to 14%), extremely fine particle size, high activity and strong cohesiveness. The coal is transported into the coal humidity control device. The feeding device needs to transport the raw coal with an inclination angle. The coal humidity control system has strict restrictions on the oxygen content. Since the coal humidity control device is a negative pressure operating area, the feeding device must also have good airtight performance. [0003] The traditional technology uses an inclined mater...

Problems solved by technology

[0003] The traditional technology uses an inclined material conveying chute as a means of conveying wet coal, and uses an electric vibration anti-blocking device as an auxiliary conveying equipment for the chute feeding of the coal humidifier. Although some measures are taken for the equipment material and welding strength, The situation of coal material sticking to the side wall of the inclined chute is still very serious, and often occurs that the coal material is not conveyed smoothly, the coal material sticks to the side wall, the cross section of the coal material flow is reduced, and the violent vibration of the anti-blocking device causes the chute conveying equipment to crack, etc. Make the coal humidity control system unable to operate continuously and stably
