Description

A kind of dehydration house rinse-system

Technical field

The utility model is related to technical field of sewage, in particular to a kind of dehydration house rinse-system.

Background technology

Facing mankind water crisis has been undisputable fact.China is increased to urban infrastructure construction and environmental protection Input strengthens comprehensive environmental improvement, so as to which gross contamination emission be made to be effectively controlled, some areas and city environmental quality It makes moderate progress.But according to environmental monitoring results statistical analysis, China's water pollution situation is still very severe, every pollutant emission Total amount is very big, and pollution level is still in quite high level.

Modern sewage treatment technology, is divided by degree for the treatment of, can be divided into level-one, two level and tertiary treatment, generally according to water The going of matter situation and treated water always determines sewage disposal degree.Coagulation is mainly removed in sewage in suspended state Solid pollution substance, physical treatment process largely can be only done the requirement of coagulation.By the sewage of coagulation, BOD mono- As can remove 30% or so, discharge standard is not achieved.Coagulation belongs to the pretreatment of two stage treatment.Two stage treatment mainly removes Make organic dirt up to more than 90% in colloid and the organic pollution materials (BOD, COD substance) of dissolved state, removal rate in sewage Dye object reaches discharge standard, and at present using being more widely staple fiber, for removal efficiency up to 95%, outlet effect is good.Three Grade processing is further processed organic matter difficult to degrade, nitrogen and phosphorus etc. and can result in soluble inorganic matter of body eutrophication etc.. Main method has biological carbon and phosphorous removal method, coagulant sedimentation, sand filtration method, active carbon adsorption, ion-exchange and electroosmose process Deng.

Dehydration is a committed step in sewage disposal, but existing dehydration house rinse-system easily blocks, The clear water of supernatant or rinse-system is caused to overflow, damages sewage disposal device.

Utility model content

For the above-mentioned prior art the problem of, the utility model provide a kind of dehydration house rinse-system, the flushing System facilitates observation, can find to block in time, avoid overflow.

To achieve the above object, the utility model provides following technical solution：

A kind of dehydration house rinse-system including knife gate valve and supernatant canal, is equipped with successively between knife gate valve and supernatant canal The transparent hose and cast iron pipe of connection, one end access supernatant canal of the cast iron pipe, the both ends of the transparent hose lead to respectively It crosses stainless steel pipe collar to be fixedly connected with knife gate valve and cast iron pipe, the both sides of the knife gate valve are equipped with wash tub pipe, the flushing The water outlet of water pipe is close to knife gate valve into mud side.

Further, the internal diameter of the transparent hose is 200mm.

Further, the internal diameter of the cast iron pipe is 200mm.

The beneficial effects of the utility model are as follows:It being matched using transparent hose and cast iron pipe, transparent hose facilitates observation, Stopping state in pipe can be grasped in time, and it is convenient to replace, and cast iron pipe can be embedded in underground or outdoor layout, and service life is long.

Specific embodiment

In order to which those skilled in the art is made to more fully understand the technical solution of the utility model, with reference to the utility model Attached drawing carries out the technical solution of the utility model clear, complete description, and based on the embodiment in the application, this field is general Other similar embodiments that logical technical staff is obtained under the premise of creative work is not made, should all belong to the application The range of protection.

Embodiment one：

As depicted in figs. 1 and 2, a kind of dehydration house rinse-system, including knife gate valve 2 and supernatant canal, knife gate valve 2 and supernatant It is additionally provided between liquid canal and is sequentially connected transparent hose 3 and cast iron pipe 4, one end access supernatant canal of cast iron pipe 4, transparent hose 2 Both ends be fixedly connected respectively by stainless steel pipe collar with knife gate valve 2 and cast iron pipe 4.The internal diameter of transparent hose 3 is 200mm.Casting The internal diameter of iron pipe 4 is 200mm.The inside of cast iron pipe 4 is further sleeved with pvc pipe 5, and the outer diameter of pvc pipe 5 is slightly less than the interior of cast iron pipe 4 Diameter is 196mm, the thickness 1mm of pvc pipe 5, and there are one small gaps 41 between pvc pipe 5 and cast iron pipe 4, and pvc pipe 5 is facilitated to block After be drawn off replacing.The both ends of pvc pipe 5 are fixedly connected respectively with cast iron pipe 4, and 43 envelope of sealing joint strip is used at the gap of end It is stifled.With certain sludge in the water discharged due to dewaterer 1, line clogging is be easy to cause, cast iron pipe 4 dismounts and dredge all expenses When it is laborious, once cast iron pipe 4 blocks, the even entire sewage disposal system of entire rinse-system is required for stagnating, serious shadow Ring the dehydration efficiency of sewage treating efficiency and rinse-system.Dehydrated tube is matched using transparent hose 3 and cast iron pipe 4, transparent Whether hose facilitates in observation tube blocks, and avoids the supernatant damage knife gate valve 2 caused by finding not in time.In pvc pipe 5 is managed It is smooth, the attachment of solid matter can be effectively reduced, reduce the generation of line clogging, while the cast iron pipe 4 in outside can be protected Internal pvc pipe 5, avoid in the operating condition pvc pipe 5 due to collide with burst caused by sewage outflow.Both ends seal Adhesive tape 43 seals, and need to only be taken out adhesive tape 43 when avoiding entering sludge between cast iron pipe 4 and pvc pipe 5, while dismantling pvc pipe 5, The fixing bolt 42 at both ends is unclamped, it is convenient for disassembly and assembly.The both sides perforation of knife gate valve 2 is equipped with wash tub pipe 6, flushing water The water outlet of pipe 6 is close to knife gate valve 2 into mud side, and after dewaterer 1 is stopped, knife gate valve 2 is closed, and wash tub pipe 6 is to disconnecting link 2 side of valve, dewaterer 1 and pipeline between the two are backwashed, and sludge is avoided to be bonded in this section, influences to reuse.

In addition, it should be understood that although this specification is described in terms of embodiments, but not each embodiment is only wrapped Containing an independent technical solution, this description of the specification is merely for the sake of clarity, and those skilled in the art should It considers the specification as a whole, the technical solutions in each embodiment can also be properly combined, forms those skilled in the art The other embodiment being appreciated that.
