Multi-stage disc type solid-liquid separator or dust collector

Abstract

The invention relates to a multi-stage disc type solid-liquid separator or dust collector, including a rack. A housing is arranged on the rack. A settling cylinder and a multi-stage rotary drum synchronous solid-liquid or gas-dust separation and continuous dreg discharge system are arranged in the housing. The system includes a closed settling drum. A drum assembly formed by laminating multiple stages of rotary drums is coaxially arranged in the settling drum. The drum assembly is fixed on a hollow shaft and follows the hollow shaft driven by a driving motor to rotate in the housing. The drumassembly performs solid-liquid or air-dust centrifugal separation of raw sewage or dust step by step, and is synchronous with the settling drum to perform secondary solid-liquid separation or air dustcentrifugal separation. The multi-stage disc type solid-liquid separator or dust collector also includes a raw sewage or dust continuous dreg discharge system, a settling drum secondary timed dreg discharge system, a sewage or dust feeding system and water discharge and gas discharge systems. During operation, the objectives of fully automatic continuous sewage or dust feeding, continuous dreg discharge, pure water discharge and pure gas discharge can be achieved as a whole. The multi-stage disc type solid-liquid separator or dust collector is replacement equipment for sewage or dust removaltreatment in the breeding industry, sewage treatment plants or cement plants.

Description

technical field [0001] The technology relates to a solid-liquid separation or dust removal technology, which is used as a solid-liquid separation or dust removal machine and belongs to the technical field of sewage or dust treatment. Background technique [0002] At present, the disc centrifugal separators on the market rely on the centrifugal force generated by the ultra-high-speed operation of the disc in the drum to separate the solid and liquid in the drum. When the sediment in the drum accumulates to a certain height in the sediment tank space The complex slag discharge device is used to discharge slag at regular intervals. This structural design has the following disadvantages: 1. Since the speed is almost all over 6000 rpm, the ultra-high speed operation results in poor structural stability of the whole machine, and the design and manufacturing accuracy requirements are very high. High, difficult to manufacture, and high cost; 2. Since the drum disc is a single-stage ...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned technical problems, the object of the present invention is to provide a multi-stage disc type solid-liquid separator or dedusting machine to solve the problem of high speed, complicated manufacture, high precision, and large investment cost of the disc centrifuges currently on the market. The liquid separation efficiency is low, the slag discharge device is complex, the water content of the discharged sediment is high, and the dust bag is easy to block when the dust collector is operating, the air flow is small, the efficiency is low, the equipment structure is complicated, there are many wearing parts and it is not resistant to high temperature, etc.
