Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveying, in particular to an improved scraper conveyor with emergency discharging. Background Art

[0002] A scraper conveyor is a conveying equipment that uses a scraper chain to pull bulk materials in a trough. It consists of an open trough, a traction chain, a scraper, a head drive sprocket and a tail tensioning sprocket. The reciprocating motion of the scraper chain pushes the material from the feed port to the discharge port. Scraper conveyors are used to convey sludge in the sewage treatment process.

[0003] At present, in the scenarios of mechanical dehydration and deep dehydration of sludge, for the technical use scenarios of the snail stacker in conjunction with the dryer, the sludge needs to be dehydrated through the snail stacker, and the dehydrated sludge is transported to the dryer through the scraper conveyor for deep dehydration. Usually, there should be an emergency discharging function in the sludge treatment process, and the emergency discharging function ensures that the treated sludge can still be discharged when the equipment is maintained or fails to avoid impact on the environment. The existing emergency discharging process requires a large amount of space to store emergency discharging equipment, and some factories have limited space, which may make emergency treatment operations more difficult to implement. In addition, when the snail stacker is just started, there may be a lot of water, and additional drainage equipment needs to be added to drain the excess water, which is more troublesome to operate. Therefore, an improved scraper conveyor with emergency discharging is proposed to solve the above problems. Utility Model Content
