Description
Technical field
The present invention relates to a kind of sewage disposal technology apparatus field, in particular to a kind of sewage plug-flow sundries separator.
Background technique
With the continuous development of industrialization and urbanization, country continues to increase the power to industrial wastewater and sanitary sewage disposal
Degree, sewage treatment plant's scale of construction is increasing, and sewage impeller is the key equipment of sewage treatment, and sewage impeller is extensive
It is that the technical process water circulations such as sewage treatment plant's nitrification, denitrification and dephosphorization are stirred applied to the low speed pushing flow of sewage treatment plant
The ideal chose of mixing equipment；Usual sewage treatment requires continuous operation, it is necessary to assure the drainage flow on concrete technology node,
So that it is guaranteed that sewage treatment overall effect is up to standard, therefore it is required that the effect of sewage impeller and equipment quality are higher and higher.
Existing submersible water impeller is mainly by impeller, mechanical sealing base, speed reducer, bearing block, motor and sliding sleeve component group
At；Sliding sleeve component is mounted on the tail portion of motor case by fastener, and speed reducer, bearing block use the machine of fastener and motor respectively
Shell phase connection, mechanical sealing base are mounted on speed reducer by fastener, and impeller is assemblied in the end of the output shaft of speed reducer, are used
Locking nut is fixed, and impeller and mechanical sealing base keep certain gap.Submersible water impeller is horizontally mounted by speed reducer
On the bracket of bottom of pond, the course of work is starting motor, and the impeller Stirring liquid being mounted on speed reducer output shaft makes
Liquid medium, which is mixed, does work to sewage, and the axial thrust of generation mixes sludge water, prevents sludge settling, pushes water flow equal
Uniform flow is dynamic.
It is in the prior art the disadvantage is that: because of submersible flow driver impellor enlarged diameter, it is desirable that miscellaneous in sewage when low speed rotation
Object and sludge cause submersible water impeller to bear biggish impact load, larger to the aging effects of submersible water impeller；Even directly
Influence the service life of impeller；Existing submersible water impeller is horizontally arranged on the bracket of bottom of pond, and installation lifts by crane, is difficult in maintenance,
It is often highly difficult when causing the use, maintenance, adjusting of actual submersible water impeller scene institute；In order to make sewage uniform throughout, simultaneously
Keep drainage flow in pond, used submersible water impeller impurity is more, bad environments under conditions of, long-term continuous operation is easily made
Therefore phenomena such as at impeller corrosion and scaling or leak electricity short-circuit, configures the higher cost of submersible water impeller, and be easy damage
It is bad, it is not convenient for safeguarding.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of sewage plug-flow sundries separators, using semi-submersible type plug-flow
Device is cooperated by net cylinder and spiral plate and increases plug-flow effect while reducing plug-flow resistance, and sundries support is arranged at net cylinder center
Plate and sundries do not have slideway, are lifted the sundries in sewage by tuck, and collect in sundries supporting plate, are arranged by sewage along slideway
Out, by mode partly latent, motor is external with mechanical part, substantially increase impeller use and maintenance work, by plug-flow with
Sundries separation becomes one, and long service life, plug-flow and sundries good separating effect, long-term continuous operation will not leak electricity short
Road phenomenon.
