Traversing spiral discharge device for stock bin and discharging method

Abstract

The invention relates to a traversing spiral discharge device for a stock bin and a discharging method. The traversing spiral discharge device comprises a round stock bin, wherein the round stock bin is fixed at the top of a mounting base; a feeding opening is formed in the center of the top of the round stock bin; an access door is arranged on a side edge of the feeding opening; a pressure relief cone cover is mounted inside the round stock bin; a primary rotating motor is mounted inside the pressure relief cone cover; the primary rotating motor and a transmission case are connected with each other and drive a spiral shaft to rotate along the axis of the spiral shaft; a discharging opening is formed in the bottom of the round stock bin; a rotational transmission system is fixedly mounted on a mounting base on the side edge of the discharging opening; the rotational transmission system drives the spiral shaft to conduct 360-degree rotational motion along the axis of the round stock bin. The traversing spiral discharge device is capable of facilitating material delivery, effectively preventing a charging basket from being blocked, boosting discharge efficiency, ensuring discharge safety and reducing the intensity of manual operation.

Description

technical field [0001] The invention relates to a garbage unloading device and a material unloading method, which are used for new environment-friendly storage, unloading, and feeding equipment for garbage power plants, biomass power plants, paper mills, sugar factories, renewable energy companies, and the like. Background technique [0002] The existing storage and discharge equipment for domestic garbage, straw, rice husk, bark, straw, wood chips, bagasse, industrial recycled rubber, cloth bags and other materials is a double-screw feeder, which is a pair of screw shafts with fixed directions. To or relative rotation, the material is pushed out by the helical blade. After the material around the screw shaft is conveyed, due to the particularity of the material such as large internal friction, humidity, and adhesion, the surface tension of the material forms an arch, and the material will not fall by itself, forming a material cavity. At this time, the double-axis screw Th...

AI Technical Summary

Problems solved by technology

When the material is stored out of the warehouse, it cannot rely on its own gravity to make it fall naturally. The material is easy to arch, resulting in serious blockage of the warehouse. Conventional mechanical vibration and air vibration methods cannot allow the material to fall continuously, often resulting in material accumulation that cannot be discharged. The phenomenon of material must be discharged manually, which cannot guarantee the continuous normal operation of the industrial production line; manual material not only increases the labor intensity of workers, but also generates a lot of dust, pollutes the environment, and also increases the possibility of dust explosion, which has a major impact risk of equipment damage and personal injury

[0004] Moreover, in order to prevent material clogging, it is usually carried out manually in 3 shifts for 24 hours, which is extremely labor-intensive. At the same time, due to the fermentation of the material in the silo, the material has a relatively high heat and pungent smell. Dust, causing serious pollution to the environment, has health hazards to the operators who poke the material, and what is more serious is that the fermentation of the material produces methane, accompanied by a large amount of dust when the material is poked, there is a significant risk of dust explosion, and there are serious equipment Hazards of damage and personal injury
