Abstract

The utility model relates to a spiral waterflow high efficiency sewage treatment putting-down machine, which comprises a metal external cylinder (1), an internal cylinder (2), a center column (3), a screw paddle (4), a pipe chute or a chute board (5), a water inlet pipe (6 ), a water collecting sump (7), a sludge pipe (8) etc. The lower end of the external cylinder (1) is closed, and the upper end may be closed and may also be unclosed; the upper end of the internal cylinder (2) is closed, and the lower end is opened and arranged inside the external cylinder (1); the center column (3) is arranged inside the internal cylinder (2); both ends of the column may be closed or only one end to be closed. The utility model is characterized in that comparing with the ecumenical putting-down with own gravity, the putting-down machine is added with a centrifugal putting-down force via creating the circumrotating state of water flow, thereby the efficiency and speed of solid-liquid separation and further enhance the solid-liquid separation putting-down is advanced further; the floor space of the equipment is reduced; the cost of the equipment is dropped.

Description

Spiral water flow type high-efficiency sewage is handled settler

Technical field

The utility model has related to technical field of sewage treatment equipment, and particularly a kind of spiral water flow type high-efficiency sewage is handled settler.

Background technology

Sewage disposal now generally all adopts technology such as physics method, bioanalysis, chemical method and physico-chemical process to handle, and the Separation of Solid and Liquid sedimentation is an indispensable part in the wherein technological process.Adopting in the settler of gravity precipitation, settling efficiency is relevant with settling area, and area is big more, and effect of settling is good more.Therefore often floor space is big in general sewage treatment project, and this seems under the environment of current land resource growing tension, and the cost of sewage disposal is higher, and the settling efficiency that improves the Separation of Solid and Liquid settler is the research direction of current settler.In order to overcome the deficiencies in the prior art, the present utility model a kind of efficient Separation of Solid and Liquid settler, it is by causing the current rotation status, Duoed a centrifugal force sedimentation than general from the gravity sedimentation, thereby Separation of Solid and Liquid settling efficiency and speed have further been improved, reach the minimizing occupation area of equipment, reduce the purpose of equipment cost.

Summary of the invention

The utility model is equiped with sludge pipe by metal outer cylinder, inner core, flight, inclined tube or swash plate, water inlet pipe, sludge pipe, bottom, the urceolus lower end closed, the upper end can be sealed also and can not seal, inner core upper end closed lower ending opening is arranged in the urceolus, newel is arranged at Nei Jiannei, can closed at both ends also can seal by an end.

Be equiped with flight between newel and the inner core.The urceolus top is equiped with water leg, and the bottom is equiped with sludge pipe.The inner core top is equiped with water inlet pipe, blast pipe, oil exit pipe respectively.The inner core upper end is equiped with the screens of wire establishment.Newel can be a hollow, also can be solid, and shape can be cylindrical, also can be taper shape.

Describe the utility model in detail below in conjunction with accompanying drawing.

Description of drawings

Accompanying drawing 1, accompanying drawing 2, be structural representation of the present utility model

Add the sewage that flocculates after the related agents and enter inner core (2) from water inlet pipe (6), because volume increases suddenly, flowing velocity slows down, by continuing to walk downward behind the screens (12), behind flight (4), current are the circulation state, so water walks downward twist, at this moment the wadding grain in the sewage is on the one hand owing to sink from gravity, on the other hand because past newel (3) convergence of rotary centrifugal force, attached to thickening down landing on the post jamb of center, little wadding grain constantly converges on the post jamb of center and top wadding grain collision, is combined into the down landing of bigger wadding again.Current enter urceolus (1) after by inner core (2) lower end, and at this moment volume increases again suddenly, form decrease of speed, help the wadding grain and sink.At this moment water still is rotation status; spirality slowly rises between urceolus (1) and inner core (2); at this moment the wadding grain is assembled to inner core (2) under centrifugal action on the other hand gradually on the one hand by descending from gravity, is combined into the landing of bigger wadding grain on the outer wall attached to inner core.The bigger wadding grain of flco formation that a less wadding one side moves towards the center on continuous collision inner core (2) wall sinks, and collides the further bigger wadding grain sinking that forms with the wadding grain superposed layer that sinks from top to bottom on the other hand.When current passed through inclined tube or swash plate (5), because the shallow layer settling principle is quickened sedimentation, last clear water was drained by water leg (7) by overflow launder (9), and mud converges to the bottom and drains by sludge pipe (8).Gas in the sewage is drained from blast pipe (10), and oil is drained from oil exit pipe (11).

The advantage of this equipment is to collect from gravity sedimentation, centrifugal force sedimentation, an increase wadding grain collision adhesion chance and makes wadding The big sedimentation of grain length, inclined tube or swash plate help four kinds of subsidence mechanisms such as heavy in one, have realized at limited equipment container In strengthen most possibly settling efficiency, thereby reach the minimizing occupation area of equipment, reduce equipment cost, improve The purpose of sinking speed.
