Description

A kind of extrusion dehydration integrated apparatus

Technical field

The present invention relates to a kind of urban sewage treatment technology field, particularly a kind of with the flocculation of the process of the solid substance in the municipal effluent, extruding, the isolating device of dehydration realization.

Background technology

Municipal effluent complicated components such as municipal wastewater, trade effluent, mud and mud, people, animal ight soil; In sewage, dewater outside the branch; Also comprise a large amount of suspensions, floating, precipitated solid material; To not be difficult to carry out next step municipal sewage treatment technology if do not carry out detached job, directly discharging will pollute environment.

Treatment process of the prior art is in sewage, to drop into flocculation agent, makes the bigger condensation prod of suspended particle cohesion becoming that wherein comprises, and through the method for mechanical filter extruding solid is effectively separated with liquid.Application number: the disclosed technical scheme of patent document of 201020233112.9 " concentrate flocculation dewatering all-in-ones " is: comprise casing, retort, rotation filter frame, threaded rod, concentrate turning axle, squeezing turning axle, screw-blade, nylon brush, crush cones, fixing screen drum; Stainless steel wedge shape grizzly bars etc., interior is divided into enrichment region and pressed zone.This design is imported screw compressor with solid substance compression dehydration then with filtering through filter frame earlier behind the sewage flocculation, and the two separately carries out; And screw compressor only is designed with crush cones at shaft tail end, causes this unit processing power low, and the table of equipment number is many; Manometric efficiency is low, and bulk treatment sewage ability is relatively poor, and treatment capacity can not satisfy the need of work at larger process station; If use the multiple devices concurrent job, then can account for equipment land used, increasing energy consumption more.

Summary of the invention

In order to solve the technological deficiency that prior art exists, the object of the present invention is to provide a kind of extrusion dehydration integrated apparatus, can significantly improve the ability of disposing of sewage, facility compact, equipment takes up an area of few, and extrusion dehydration is more thorough.

To achieve these goals, technical scheme of the present invention is:

A kind of extrusion dehydration integrated apparatus mainly comprises reactor drum part, extrusion dehydration part and cover part,

The reactor drum part: reactor lower part has Reactor inlet, and reactor drum top has reactor outlet, and reactor outlet is communicated with its inner filter frame space through pipeline from the outer cover end, and reactor drum has flocculation agent and adds inlet, has level gauge on the reactor drum;

The extrusion dehydration part: screw shaft runs through the outer cover both ends, and screw shaft one end connects the screw shaft reducing motor, the whole sheathed cone in the screw shaft outside; The cone outside has the screw-blade of fixing on it; Screw-blade is that the screw-blade edge has hairbrush from the little variable-pitch auger blade of rear support leg side direction front leg strut side pitch gradual change, and filter frame is enclosed in the screw-blade outside; Filter frame and outer cover both ends are fixed; The filter frame outside has the spray equipment by the flushing arrangement driven by motor, and spray equipment has most the Flushing nozzles towards filter frame, and spray equipment has flush head;

Cover part: be fixedly connected front leg strut and rear support leg on the underframe, outer cover is fixed on front leg strut and the rear support leg, and front leg strut is longer than rear support leg; It is skewed that outer cover is, and its front leg strut end has discharge port, and the leg ends downside has filtrate outlet thereafter; Filtrate outlet is the communicated drainage mouth by the road, has butterfly valve on this pipeline, and being covered with up and down, two portions fasten; Its buckling parts is sealed by joint strip, and its first half has viewing window.

Because after adopting such scheme, the utility model in use, municipal effluent is transfused to reactor drum; Generate flocks with the flocculation agent hybrid reaction, be transfused to then in the filter frame of extrusion dehydration part, wherein contained humidity spills through filter frame; The screw-blade that mud caught on a filter is rotated is upwards pushed compression, further discharges wherein and discharges from discharge port behind the moisture, and filtrating is outside filtrate outlet is discharged body; Spray equipment cleans filter frame to filter frame inject high pressure water, prevents to stop up.The utility model is once accomplished the dehydration extrusion process through an equipment, can jumboly carry out treatment process, significantly improves the ability of disposing of sewage; Facility compact; Equipment takes up an area of few, and whole sheathed cone in the screw shaft outside and use variable-pitch auger make extrusion dehydration more thorough.
