High-moisture sludge uniform-distribution drying device

Abstract

The invention discloses a high-moisture sludge uniform-distribution drying device which comprises a tank body, wherein a feeder is arranged above the tank body; two conveyer belts parallel to each other are arranged at the upper part inside the tank body; a molding structure is arranged below the conveyer belt; the molding structure comprises an upper extrusion belt and a lower extrusion belt parallel to each other; a spreading plate is arranged at the top of the tank body; a transfer plate is arranged between the two conveyer belts; both the upper surface and the lower surface of the transferplate and the bottom of the spreading plate are inclined surfaces; the upper end of the transfer plate is fitted to the conveyer belt at the upper part; a hot air fan and an exhaust hole are respectively arranged on both sides of the tank body; and a guide plate is arranged at the front end of the molding structure. Due to arrangement of the double conveyer belts, the spreading plate and the transfer plate, the situation that up and down drying states are not identical because of one-way conveying can be avoided, sufficient drying of sludge can be ensured, the sludge is further extruded intopieces by the molding structure and is discharged outside the tank body, the process is continuous, the drying effect is thorough, and the problem that common drying equipment is non-uniform in dryingeffect can be avoided.

Description

technical field [0001] The invention relates to environmental protection equipment, in particular to a drying device for evenly distributing high-moisture sludge. Background technique [0002] Sewage plants use sludge dryers to dry and dehydrate sludge. The existing sludge dryers are usually of paddle type or drum type, which require agitating blades in the dryer. The processing is more complicated. Maintenance is also difficult. [0003] Chinese Patent Application Publication No. CN108706851A discloses a low-temperature environmentally friendly sludge dryer, which uses a conveyor belt to transport the sludge and cut the sludge into strips, so that large quantities of sludge can be dried in a continuous and orderly manner. Drying, but there are still some problems, such as the direction of sludge is one-way, and this causes the upper and lower sides to be heated evenly, which also causes inconsistent drying effects.
