Abstract

The utility model relates to a wastewater purifier which belongs to the technical field of water treatment equipment and is composed of a shell body and a filter tank, wherein the filter tank forms a conical shape, a side wall is a filter layer and the bottom part of the filter tank is connected with a rotating shaft. The shell body is arranged at the outer part of the filter tank, and the upper cover of the shell body is fixed with a shaft barrel. The shaft barrel inwards extends to the center of the filter tank, a plurality of groups of water mixing paddles are fixed on the shaft barrel and the shaft barrel is driven to work by a motor. The utility model overcomes the defect of treating wastewater with a static filter method, causes the wastewater to realize purification in a rotating dynamic process and improves purification efficiency. Simultaneously, when the wastewater is operated in corresponding sealed space, the utility model lightens air pollution, has the advantages of small occupation area, less investment, and convenient maintenance and replacement and is especially suitable for small and medium sized pollution discharging enterprises to use.

Description

A kind of effluent treatment plant

(1) technical field

The utility model belongs to the water treating equipment technical field, relates in particular to a kind of effluent treatment plant.

(2) background technology

At present, domestic many medium and small blowdown enterprise mostly adopts the precipitator method and static filtering method to finish to the processing of sewage.Its treatment process is earlier sewage to be entered settling tank or filtering basin sewage is precipitated and to filter, after waiting to precipitate and filtering again with its outside discharging.This treatment process requires the floor space of sewage disposal device bigger, owing to be open work, atmospheric pollution is serious, and ubiquity input expense height, and the problem that processing efficiency is low causes cost of water treatment to increase, and most of small enterprises is difficult to bear.

(3) summary of the invention

The purpose of this utility model be to provide a kind of occupation of land less, efficient height, the light effluent treatment plant of atmospheric pollution.

For achieving the above object, adopt following technical scheme: effluent treatment plant, comprise filter vat, particularly filter vat is truncated cone-shaped, and is up big and down small, upper opening, the filter vat sidewall is a filtering layer, and filtering layer is sandwich structure, and the interlayer between the interior outer side wall is a filtering material, filter vat bottom fixed rotating shaft, rotating shaft is by motor drive, and the filter vat outside is a housing, and case top lid is beam barrel fixedly, beam barrel stretches to the center of filter vat, by motor drive, with the fixing some groups of water-mixing oars of axial line vergence direction, sewage water inlet pipe is arranged in the beam barrel inner chamber on beam barrel, side in the filter vat upper body is provided with the spillway of slagging tap, and lower housing portion is provided with treated water outlet.

Uniform circular permeable hole on the outer side wall in filter vat, the end of water-mixing oar is scraper plate fixedly, and the cambered surface of the outer of each scraper plate and filter vat inwall matches.

This effluent treatment plant has overcome the deficiency that the static filtering method is disposed of sewage, and allows sewage disposal finish in filter vat, and whole scavenging process is dynamic, rotation along with filter vat, sewage can improve purification efficiency faster by filtering layer under the reverse agitaion of water-mixing oar.Scraper plate can will scrape attached to the foreign material on the inwall, makes its unlikely obstruction permeable hole.Up big and down small truncated cone-shaped filter vat structure, the foreign material of being convenient in the sewage are separated in rotatablely moving, and spillway is discharged by slagging tap.Housing parcel filter vat is finished water treatment in the space of a relative closure, reduced atmospheric pollution.

(4) description of drawings

Fig. 1 is the structural representation of effluent treatment plant.

Fig. 2 is the local structure synoptic diagram of filter vat sidewall.

(5) embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

By Fig. 1, effluent treatment plant is made of filter vat 1 and housing 2.Filter vat 1 is truncated cone-shaped, and is up big and down small, and upper opening, its sidewall are filtering layer 3, and filtering layer 3 is sandwich structure, is made up of inwall 31, filtrate 32, outer wall 33, and filtrate is selected filtering materials such as quartz sand, gac for use.The structure of inwall 31, outer wall 33 is seen Fig. 2, can stop foreign material again simultaneously for the ease of crossing water, and it is designed to the structure of the uniform some circular permeable holes 34 in surface.The fixed rotating shaft 4 of going to the bottom of filter vat 1, rotating shaft 4 connects with the plumer block 5 of housing 2 bottoms, and is driven by electric motor 6.The top of housing 2 is a loam cake 7, fixing beam barrel 8 on it, and beam barrel 8 puts in downwards in the filter vat 1, and places the center of filter vat 1, is fixed with plumer block 9 on the loam cake 7, and beam barrel 8 connects with plumer block 9, and is driven by electric motor 10.

On the outer wall of beam barrel 8, fix three groups of water-mixing

oars

81,82,83 along the axial line vergence direction, two every group, be fixed with scraper plate 811 in the end of each water-mixing oar, the cambered surface of the outer of each scraper plate and filter vat inwall 31 matches.Sewage water inlet pipe 11 is arranged in the inner chamber of beam barrel 8, and housing one side has the spilling water of slagging tap 12 in the outer suitable for reading of filter vat 1, and lower housing portion is established treated water outlet 13.

During work, sewage is entered in the filter vat by sewage water inlet pipe, after reaching a certain height, the control water intake velocity, motor drive filter vat and beam barrel rotate, the two does the motion of different directions different rotating speeds, sewage passes filtering layer under action of centrifugal force, be cleaned after filtering through quartz sand, charcoal absorption, ooze out by the filter vat outer wall, flow out from treated water outlet.Foreign material such as the waste residue in the sewage can not filter by filter screen, under the agitaion of water-mixing oar, move upward along the filter vat inwall, and after being stopped by case top lid, spillway is discharged through slagging tap.Can be scraped by scraper plate attached to the foreign material on the inwall and to clear up, be accompanied by the rotation of current, finally also can be thrown out of.So move in circles, sewage constantly enters and is cleaned processing.

This refining plant takes up an area of little, less investment, and purification speed is fast, and the filtrate flushing is changed all very convenient, and complete machine is easy to maintenance, and expense is low.Handle one ton of waste water with the paper mill and calculate, only need 0.1 yuan, be fit to very much medium and small blowdown enterprise and use.
