Novel energy sludge drier

Abstract

The invention discloses a novel energy sludge drier. The novel energy sludge drier comprises a machine body, wherein a feeding opening is formed in one side of the upper part of the machine body in a sleeving manner; a pulling plate is clamped at the bottom of the feeding opening; in addition, an air inlet is formed in the other side of the feeding opening; an air heater is arranged on one side below the machine body through a conduit in the sleeving manner; besides, a discharging pipe is arranged in the center below the machine body in the sleeving manner; an electromagnetic switch valve is arranged inside the discharging pipe; a dried sludge collecting tank is arranged below the discharging pipe in a sleeving manner. According to the novel energy sludge drier disclosed by the invention, a solar silicon plate is arranged on the back of the novel energy sludge drier and used for gathering solar energy used as an energy source; a stirring rod is mainly arranged inside the novel energy sludge drier and can rotate through the rotation of the motor, so that the aim of stirring is achieved; a circular scraper is connected to the inner part of the machine body through an XTL electric telescopic rod; through the stretching of the XTL electric telescopic rod, the circular scraper can do left-right reciprocating motions, so that sludge on the inner wall of the machine body can be scraped off.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular to a new energy sludge dryer. Background technique [0002] Sludge drying is the process of removing most of the water content from sludge through percolation or evaporation, which generally refers to the use of self-evaporating facilities such as sludge drying fields (beds). [0003] High-viscosity sludge drying equipment generally adopts a hot air rotary vane dryer. According to the different sludge viscosity, a two-axis rotary vane dryer (vertical, horizontal) and a three-axis rotary vane dryer (horizontal) can be used. High-humidity materials with a water content of less than 85% are dried once to a final water content of less than 12%, and the drying time is short, generally 2-10 minutes. Because the high-speed stirring blades vigorously stir the wet material, the wet material can be in good contact with the hot air. The water in the first half of the material evapor...

Problems solved by technology

[0004] However, when the existing sludge dryer is in operation, a large amount of sludge will stick to its inner wall as the drying process proceeds, which makes the internal stirring slow, reduces the drying efficiency, and is easy to block. sex is not very strong
