A kind of positive pressure sealing quick opening cover buried scraper conveyor

Abstract

A positive-pressure sealing and rapid cover plate opening embedded scraper transporter comprises a head part, a tail part and an intermediate section, all of which are provided with access doors. The head part is provided with a head sealing mechanism, and the tail part is provided with a tail sealing mechanism. The intermediate section is provided with a sealing and rapid upper cover opening mechanism, and the access doors are provided with sealing and rapid viewing door opening mechanisms. According to the positive-pressure sealing and rapid cover plate opening embedded scraper transporter, through well sealing on the shaft stretching-out end of the embedded scraper transporter, the access doors, an upper cover and other places where dust is possibly generated, environment pollution is reduced; and through the improvement on the access doors and an upper cover locking mechanism, rapid cover opening is convenient, and time is saved.

Description

technical field [0001] The invention relates to a buried scraper conveyor, in particular to a buried scraper conveyor with a positive pressure sealed quick-opening cover. Background technique [0002] Buried scraper conveyor is a kind of continuous transportation equipment for conveying bulk materials by means of moving scraper chains in a closed shell with a rectangular cross section. The buried scraper conveyor has the advantages of simple structure, large capacity, easy operation, and flexible process layout. It can be used for horizontal conveying, inclined or vertical conveying, single machine or multi-machine joint use, and multi-point feeding and unloading. Because the shell is closed, it can significantly improve the working environment of workers and prevent pollution when transporting dusty, toxic, high-temperature, explosive and other materials. It is widely used in metallurgy, mining, ports, chemicals, building materials, thermal power, grain and oil, and light. ...

AI Technical Summary

Problems solved by technology

[0004] 1) The gap between the head shaft in the head wheel assembly and the shaft hole on the side plate of the head shell is usually only sealed with a single packing. When there is positive pressure in the head shell, the packing box is easy to Dust leakage, a large amount of dust spills out of the shell and pollutes the environment

[0005] 2) The outer pressure plate of the head shell usually adopts a guide briquetting block, which has poor sealing performance and dust is easy to overflow from the gap between the side plate and the briquetting block

[0007] 4) The inspection doors set on the head and tail cover plates and the side plates of the middle shell are usually fixed on the edge of the door with bolts, and the opening and closing must be unscrewed and screwed with dense bolts one by one, neither Convenient and easy to cause the door edge not to be sealed

[0008] 5) The cover plate and the side plate of the middle section of the shell are usually connected by bolt components. When the equipment is overhauled, it is necessary to unscrew the dense bolts one by one to open the cover plate. After the overhaul, it is necessary to unscrew the dense bolts one by one. It is extremely inconvenient to put on the cover, and it is very inconvenient to unscrew and screw on the bolts and switch the cover plate many times, which will easily cause damage to the gasket between the cover plate and the side plate, which will affect the sealing effect and increase the maintenance cost of the equipment.
