The invention discloses a heating device for sludge drying, which comprises a first casing, an air inlet pipe, a heat recovery pipe, a first retaining ring, a second casing, an air outlet pipe, a second retaining ring, a primary Filter screen, air guide cover, heating coil, cover plate, first filter screen cover, second filter screen cover, sealing ring, etc. By setting the primary filter cover at the entrance of the first cover, and setting the first filter screen cover and the second filter screen cover on both sides of the wind guide cover, it can effectively isolate dust and avoid dust accumulation on the heating coil. Heating effect; by setting the first retaining ring and the second retaining ring, it is convenient to clamp and fix the first filter screen cover, the folded edge and the second filter screen cover on the air guide cover, and it is also convenient to disassemble, which is convenient for parts replacement and repair.
Description
Technical field: [0001] The invention belongs to the technical field of sludge treatment equipment, and in particular relates to a heating device for sludge drying. Background technique: [0002] The sludge extruder is the equipment in the sewage purification treatment, that is, the equipment that extrudes the sludge into various shapes, and the strip extruder is the equipment that extrudes the sludge into strips. By extruding the sludge into a strip shape, the accumulation height of the material can be consistent, the void ratio can be increased, the contact area between the sludge and the hot air can be increased, the flow resistance when the hot air penetrates the drying zone can be reduced, and the drying process can be effectively improved. efficiency. The working principle of the existing sludge extruder is to change the volume by rotating the cross head in the extruder, so that the sludge is extruded into strips from the discharge hole of the drawing plate, and the s...
