Continuous sludge treatment device

Abstract

The invention discloses a continuous sludge treatment device, comprising a feeding hopper, a first driving motor and a second driving motor; the feeding hopper is connected with a dehydration box, and a screen drum is arranged in the dehydration box, and the screen drum is covered with A rack ring is provided, and the rack ring is rotatably connected with the sieve drum through a bearing; the right side wall of the rack ring is fixedly connected with a symmetrically arranged strip brush; the right side of the sieve drum is connected with a drying machine through a sludge pipe box. The present invention is provided with a screw extrusion dewatering device with a rotating brush to avoid clogging of screen holes, ensure continuous dewatering operation, and have high dewatering efficiency; the present invention is composed of a heating plate, a flat roll and a scraper. The drying device can efficiently and uniformly heat the sludge to improve the drying efficiency; the invention is provided with an auxiliary drying device composed of a hot air nozzle, a pulverizing blade and a turning plate to thoroughly dry the sludge and ensure the drying effect.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a continuous sludge treatment device. Background technique [0002] Sewage treatment plants produce a large amount of sludge every day. These sludges need to be treated by reducing, stabilizing and harmless processing such as concentration, tempering, dehydration, stabilization, drying or incineration of sludge. process. [0003] Common sludge dewatering and drying equipment is separate and independent equipment, which needs to transfer raw materials, cannot carry out continuous production, and has low treatment efficiency. In common screw extrusion dehydration devices, the screen holes of the dehydration cylinder are prone to blockage. It needs to be shut down for dredging, which affects the normal production and wastes time. In addition, the bolt extrusion dehydration device can only remove a certain amount of water, so it needs to use a drying device. The traditional d...

[0003] Common sludge dewatering and drying equipment is separate and independent equipment, which needs to transfer raw materials, cannot carry out continuous production, and has low treatment efficiency. In common screw extrusion dehydration devices, the screen holes of the dehydration cylinder are prone to blockage. It needs to be shut down for dredging, which affects the normal production and wastes time. In addition, the bolt extrusion dehydration device can only remove a certain amount of water, so it needs to use a drying device. The traditional drying device uses hot air to dry, and the efficiency is low. Uneven, slow drying
