Continuous sludge treatment device

Abstract

The invention discloses a continuous sludge treatment device. The continuous sludge treatment device comprises a feeding hopper, a first driving motor and a second driving motor, wherein the feeding hopper is communicated with a dewatering box, a screen drum is arranged in the dewatering box and sleeved with a rack ring, and the rack ring is rotationally connected with the screen drum through a bearing; strip-shaped brushes which are symmetrically arranged are fixedly connected with the right side wall of the rack ring; a drying box is communicated with the right side of the screen drum through a sludge pipe. With the arrangement of a screw extrusion dewatering device provided with the rotating brushes, sieve meshes are prevented from being blocked, continuous dewatering work is guaranteed, and the continuous sludge treatment device has higher dewatering efficiency; the continuous sludge treatment device is equipped with a drying device consisting of a heating plate, flat spreading rollers and scrapers, therefore, sludge is efficiently and uniformly heated, and drying efficiency is improved; an auxiliary drying device consisting of hot air spray nozzles, smashing blades and a turning plate is arranged, so that the sludge is thoroughly dried, and the drying effect is guaranteed.

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
