Description

Conveyor with embedded scraper for bulk materials

Technical Field

The utility model relates to a bulk material conveying equipment technical field, concretely relates to scraper conveyor is buried to bold material

A machine is provided. Can be suitable for the full-sealed continuous conveying of partial massive materials under the conditions of normal temperature or high temperature.

Background

In the domestic metallurgical industry, particularly under a waste heat boiler or an electric dust collector, the common lower feeding high-temperature ash conveying equipment has the defects of large fault repairing difficulty, difficulty in controlling the height of a material layer and the like due to the phenomena of oxidation, corrosion and deformation of a whole machine shell, deformation of a scraper chain, material blockage and vehicle blockage caused by caking when the material meets with damp and the like at high temperature. The method specifically comprises the following points:

1) in general, a bearing cavity and a no-load cavity of the buried scraper conveyor are not separated in a closed machine shell, the bearing cavity is arranged at the lower part of the machine shell, the no-load cavity is arranged at the upper part of the machine shell, and a chain return wear-resistant guide rail is arranged in the middle of the no-load cavity. When high-temperature materials are conveyed, the temperature of the no-load cavity quickly reaches the temperature of the bearing cavity, and the whole machine shell is oxidized, corroded and deformed at high temperature and is easy to wear or wear and perforate.

2) The scraper chain is a traction component for conveying materials, and the integral heat treatment is carried out for ensuring that the chain rod and the pin shaft have enough tensile strength and excellent wear resistance. When carrying high temperature material, the scraper chain who bears the weight of the chamber contacts with the material, makes the scraper chain temperature constantly rise because of the heat radiation of material, and no-load chamber return stroke scraper chain can not obtain effective lowering temperature. Generally, when the temperature is higher than 400 ℃, the chain rod and the pin shaft are in a tempering temperature state, the comprehensive mechanical property and the surface hardness are greatly reduced, and the friction, the abrasion, the deformation or the fracture are easy to occur.

3) And in the actual working condition state, when large materials which are not crushed, screened, sintered or agglomerated when meeting damp are encountered, extrusion blockage is easy to generate. When the material lumpiness is greater than the space formed between the scraper blade interval and the chain rod, the material can not smoothly fall into the lower bearing cavity from the upper no-load cavity and is blocked, and even if the material falls into the lower bearing cavity, the material can not smoothly flow out of the discharge opening when being conveyed to the discharge opening. Particularly, the phenomenon of material clamping of wheel grooves is easily caused at the head wheel of the head, so that the head wheel teeth or the scraper chain are seriously deformed and even broken, and equipment accidents are caused.

4) Because the part of the bearing material is arranged at the lower part of the shell, the height control device for installing the material layer is limited by the height of the shell of the bearing cavity and cannot be effectively realized, and the material layer height can be changed and controlled only by directly controlling the feeding amount.
