Non-clogging scraper feeder

Abstract

The invention relates to a non-clogging scraper feeder, and belongs to the field of industrial transport and feeding machinery equipment. The non-clogging scraper feeder comprises a shell (1), a transmission device (2), a head shaft assembly (3), a tail shaft assembly (4), scraper chains (6) and a scraper (7), wherein the shell (1) is horizontally arranged, and the head shaft assembly (3) and the tail shaft assembly (4) are respectively arranged at the head and the tail of the shell (1). The non-clogging scraper feeder is characterized in that a joint of the lower end of a feeding channel (9) and the shell (1) is provided with a funnel-shaped blanking port (10) with a small upper part and a large lower part, and a supporting plate (11) is arranged under the blanking port (10) in parallel and is arranged between the upper and lower scraper chains (6); a material falling from the blanking port (10) can be accumulated on the upper plane of the supporting plate (11) in a hill shape, and a traffic adjusting device (5) capable of controlling the conveying amount of the material is arranged at one side of the supporting plate (11). The non-clogging scraper feeder has the advantages of adjusting the traffic, running reliably, preventing coal clogging and chain breaking phenomena, improving working efficiency and saving labor.

Description

technical field [0001] A non-clogging scraper feeder belongs to the field of industrial transportation and feeding machinery, and in particular relates to a scraper feeder used in thermal power plants or coal chemical plants. Background technique [0002] The scraper conveyor is a continuous transportation equipment that transports bulk materials by means of a moving scraper chain in a closed rectangular section shell. Scraper conveyors are widely used in small and medium-sized thermal power plants and coal chemical plants for raw coal transportation of circulating fluidized bed boilers and fluidized fluidized boilers. However, because the fuel coal used in a large part of small and medium-sized thermal power plants and thermal power workshops of coal chemical plants is sticky coal, when the fuel coal is slightly wet, it will cause coal blocking due to coal seam caking, especially at the short-circuit of the feed port. At the same time, due to the uneven amount of coal fall...

Problems solved by technology

However, because the fuel coal used in a large part of small and medium-sized thermal power plants and thermal power workshops of coal chemical plants is sticky coal, when the fuel coal is slightly wet, it will cause coal blocking due to coal seam caking, especially at the short-circuit of the feed port. At the same time, due to the uneven amount of coal falling, the amount of coal delivery cannot be adjusted, resulting in uneven coal input and output, resulting in blockage, and even further causing major losses such as coal breakage, conveyor chain breakage, and shutdown, hindering the workshop Normal operation will seriously affect the production efficiency; and because the coal blockage needs to be dredged manually, it will also cause a great burden to the workshop workers and take up a lot of labor
