Description

Technical Field

[0001] The utility model relates to a scraper conveyor, in particular to a scraper conveyor used for sludge transportation. Background Art

[0002] A conveyor that uses a scraper chain to transport bulk materials in a trough is called a scraper conveyor; a KS scraper conveyor whose adjacent middle trough can be bent to a limited extent in the horizontal and vertical planes is called a flexible scraper conveyor, and the working surface conveyor whose body is bent 90 degrees at the intersection of the working surface and the transport lane is called a "corner scraper conveyor".

[0003] Scraper conveyors are also widely used in sludge transportation. Sludge is the product of sewage treatment. It is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. Sludge power generation is one of the technical measures for urban sewage treatment plants to rationally develop and utilize sludge. It is a good method for sludge reduction, stabilization, harmlessness and resource utilization. The sludge needs to be placed in a dryer for processing; but because the temperature and humidity of the sludge just out of the dryer are very high, it is easy to adhere to the scraper conveyor during the conveying process of the scraper conveyor. When the sludge accumulates in the scraper conveyor to a certain thickness, it will hinder the movement of the scraper and even shorten the service life of the scraper, so it needs to be cleaned frequently. In view of this, the present application designs a cleaning mechanism for a sludge conveying scraper conveyor. Utility Model Content
