Description
Technical field
The present invention relates to a kind of equipment for silt in initial gross separation high turbidity raw sewage in drinking water emergency process, belong to technical field of drinking water treatment.
Background technology
China is the multiple country of a natural calamity, and the pollution of waterhead that the sudden water pollution accident that the natural calamities such as earthquake, flood, arid, mud-rock flow and various human factor cause causes, the on a large scale problems such as interruption that supply water occur again and again.Sudden water pollution event can produce in moment (or in short time) a large amount of polluters exceeding water body self-purification ability usually, compared with general environmental pollution, have occur suddenly, diffusion rapidly, the feature such as the serious and pollutant of harm is not clear, not only the water resource of preciousness is caused and pollute and destroy, and the serious threat people's is healthy.
When wherein processing for the high concentrtion contaminant water produced by the disaster such as earthquake or mud-rock flow, first by pretreating process, silt most of in former water to be removed, and then carry out other treatment process, and good and bad to silt removal effect of pretreating process, will produce important impact to subsequent technique.
Generally bulky grain silt in former water is removed with hydrocyclone in existing pretreatment height muddy water technique, it is that High Rotation Speed is carried out in the hydraulic blow effect produced by high-velocity flow and larger flow, under the influence of centrifugal force, solid phase particles has the trend to the sedimentation of eddy flow wall under the influence of centrifugal force, coarse granule, owing to being subject to larger centrifugal action, being discharged to the motion of cyclone wall and with contour stealth and is formed underflow bottom cyclone; The centrifugal force of fine grained then due to suffered is less, has little time sedimentation and just to discharge from overflow pipe with inward eddy and form overflow, carry out being separated of different medium by underflow with overflow.But when being in an emergency, the hydraulics of water inlet is unknown, unpredictability is large, namely flow of inlet water and flow velocity instability, when flow and flow velocity less time, might not produce the hydraulics making hydrocyclone High Rotation Speed, now hydrocyclone just loses its effect, does not also just reach expection treatment effect.
Summary of the invention
For existing emergent water pretreatment technology Problems existing, the invention provides a kind of bulky grain silt can effectively removed in high turbidity raw sewage, applied widely, treatment effect good, silt eliminating equipment by the water inlet impact of hydraulics and in the high high turbidity raw sewage of stability.
Silt eliminating equipment in high turbidity raw sewage of the present invention, realizes by the following technical solutions:

Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, in high turbidity raw sewage of the present invention, silt eliminating equipment mainly comprises process tank and transmission mechanism two parts.
As Fig. 2 and Fig. 3, process tank comprises tank body, rotary drum 6, silt water collection groove 7 and sieving water collection groove 8.Tank body upper end is provided with cloth hydroecium 2, and the upper end of cloth hydroecium 2 arranges water inlet 1, can arrange sealing ring, ensure to be tightly connected in both junctions.In tank body, bottom is provided with the silt water collection groove 7 of annular, and silt water collection groove 7 is by forming sieving water collection groove 8 between the toroidal membrane 9 outside it and inner tank wall.Tank body is provided with the silt water out 10 be communicated with silt water collection groove 7 and the sieving water out 11 be communicated with sieving water collection groove 8, see such as Fig. 4, two different water legs and two delivery ports are set, achieve the collection and discharge of silt water and sieving water being concentrated, make the husky processing procedure of whole desliming become simple and efficient.Toroidal membrane 9 outside silt water collection groove 7 is fixedly connected with basketry 4, basketry 4 is provided with silt filter screen 3.Basketry 4 with on toroidal membrane 9 between to be airtightly connected, can not seepage, be conducive to the shunting of silt water and sieving water.The top of silt water collection groove 7 is provided with rotary drum 6 (silt filter screen 3 is sleeved on the outside of rotary drum 6) in silt filter screen 3 inside, and rotary drum 6 is fixedly connected on transmission mechanism, and rotary drum 6 is tapered.Stacked on rotary drum 6 outer wall be placed with deflector 5 from top to bottom, between adjacent baffle 5, form guiding gutter.The upper end of rotary drum 6 blocks, to make outside former current direction rotary drum 6.As shown in Figure 5, there is less gap between the outermost end of deflector 5 and silt filter screen 3, make deflector 5 serve the effect of interior scraper, deflector 5 High Rotation Speed, the solid particle remained in inside silt filter screen 3 is scraped, effectively prevent the blocking of silt filter screen 3.Silt filter screen 3 and basketry 4 are also in the taper the same with rotary drum 6.Can according to raw water quality situation, change the silt filter screen 3 of different pore size order number (200 orders, 300 orders, 400 orders, 500 orders not etc.).
Silt water out 10 and sieving water out 11 place are equipped with control valve, control the keying of two outlets when being convenient to adjustment and the reply different quality of flow.
Transmission mechanism adopts V belt translation, comprises motor 14 and rotating shaft 12, motor 14 and rotating shaft 12 are all provided with belt wheel, connect belt 13 between two belt wheels.Motor 14 drives rotating shaft 12 to rotate by belt 13.Motor 14 is arranged on outside tank body, and rotating shaft 12 is vertically arranged in tank body, can be arranged on the inwall of sieving water collection groove 8 as Fig. 2 and Fig. 3.Rotary drum 6 is fixedly mounted on the upper end of rotating shaft 12.
The running of the said equipment is as described below:
Water inlet 1 is connected with outside inlet channel, starter motor 11, drives rotating shaft 12 High Rotation Speed by belt 13, the rotary drum 6 be fixedly connected with rotating shaft 12 also High Rotation Speed thereupon.Rotating speed can regulate, and can regulate the rotating speed of motor 14, equipment is run according to the operating mode of optimization process effect, fixed electrical machinery rotating speed after running according to raw water quality situation, to avoid being subject to the drawback into the impact of water hydraulic condition.Former water enters cloth hydroecium 2 by water inlet 1, is buffered to hydraulic condition balance, is conducive to the even of water distribution in cloth hydroecium 2.The former water of hydraulic condition balance is flowed out by cloth hydroecium 2 water side, the guiding gutter formed by deflector 5 on rotary drum 6 outer wall flows down, under the drive of rotary drum 6 High Rotation Speed, former water is by the effect of centrifugal force, get rid of to surrounding, wherein large particulate matter (for the aperture of silt filter screen 3) can be tackled by the silt filter screen 3 outside rotary drum 6.If flow of inlet water is excessive, a part has little time also to be blocked with bulky grain through the former water of silt filter screen 3.The solid particle remained in inside silt filter screen 3, with rotary drum 6 High Rotation Speed, scrapes by deflector 5, effectively prevents the blocking of silt filter screen 3.By the silt that scrapes with do not got rid of together with the former water of silt filter screen 3, flow down along silt filter screen 3 and import silt water collection groove 7, flowed out by the pipeline connected with silt water out 10.Sieving water, then through silt filter screen 3 and basketry 4, imports sieving water collection groove 8, is discharged carry out continuation process by sieving water out 11.
