Abstract

The invention discloses a disc scraper drying device. The device comprises a frame, a rotating shaft rotatably installed on the frame, at least one disc coaxially fixed to the rotating shaft, a scraper supporting plates in one-to-one correspondence with the discs and movably arranged on the frame, a main scraper fixed to the scraper supporting plates, a main scraper driving device used for drivingthe scraper supporting plates to act to adjust the attaching force between the main scraper and the discs, a liquid storage tank used for containing feed liquid, a liquid inlet pump pumping the feedliquid in the liquid storage tank into the material distribution device, a material distribution device outputting the feed liquid in the liquid storage tank to the surfaces of the two ends of the disc, a rotary driving device driving the rotating shaft to rotate, a heating device heating the disc, and a discharging hopper located under the lower end of the main scraper. The gap between the main scraper and the disc is automatically adjusted by the main scraper driving device, the adjusting efficiency is high, the surface of the adjusted disc surface is stressed uniformly, the service life ofthe disc is long, discharging is smooth, and solid materials are dried thoroughly and uniformly.

Description

technical field [0001] The invention relates to a waste water treatment technology, in particular to a disk scraper drying device. Background technique [0002] In the process of industrial production and wastewater treatment, it is often necessary to evaporate and dry liquid materials to obtain solid products or obtain solid materials, and then carry out recycling or reduction treatment. Drum scraper dryer is a kind of internal heating conduction equipment suitable for the above drying operation. Its working principle is: the material liquid forms a layer of 0.5-1.5mm liquid film on the surface of the drum through the film cloth device, and the heat is transferred by the drum. The inner wall is transmitted to the outer surface of the drum and then to the liquid film. As the drum rotates, the water in the liquid film is continuously and rapidly evaporated, and the remaining dry materials are scooped off by the main scraper and collected, exposed to the surface of the drum an...
