Continuous belt type sludge dryer and method for treating sludge in batches

Abstract

The invention discloses a continuous belt type sludge dryer and a method for treating sludge in batches. The continuous belt type sludge dryer comprises a feeding mechanism lifting the sludge from thebottom to the top, a feeding speed control mechanism storing sludge temporarily and controlling the sludge discharging amount and with the bottom provided with a pneumatic brake valve, a sludge cutting mechanism, a material drying system drying the sludge, a discharging mechanism and a controller processing unit. The feeding speed control mechanism is located below a discharging port of the feeding mechanism, the feeding speed control mechanism, the sludge cutting mechanism and the material drying system are sequentially arranged from top to bottom, and the discharging mechanism is close to the bottom of the material drying system; and the feeding mechanism, the feeding speed control mechanism, the sludge cutting mechanism, the material drying system, the discharging mechanism are both electrically connected with the controller processing unit. The continuous belt type sludge dryer is applicable to sludge dryers for treating small-batch sludge, semi-automated operation is achieved, the floor space is small, the equipment investment is low, the manpower cost is low.

Description

technical field [0001] The invention relates to the technical field of sludge treatment, in particular, the invention relates to a continuous belt sludge dryer and a method for treating sludge in batches. Background technique [0002] At present, the commonly used equipment for drying sludge on the market is the heat pump dryer, and the general heat pump dryer is either batch type or continuous type. There are no moving parts inside the conventional batch-type drying box, and it is usually a static material rack, tray or hook. Materials have as large a contact area as possible. This kind of work relies heavily on manual work, especially the placement of hundreds of pallets and the flattening of materials on the pallets. The workload is complicated and the labor cost cannot be ignored. Continuous dryers generally use a conveyor belt as a carrier for material transportation and drying. The feed material moves slowly with the mesh belt line, and the water gradually evaporates...
