Description
Affiliated technical field
The utility model relates to a kind of sewage intake equipment, is the squirrel-cage intake equipment with preliminary filtering function.
Background technology
The main component of municipal sewage is: sanitary sewage, production waste drainage, rainwater etc., and summer temp is 18～26 ℃, and winter temperature is more than 8～18 ℃, and pH value is generally 6～8, and the harmful foreign material of suspension and graininess are more.
The quantity of municipal sewage is very huge, and it is very wide to distribute around our life, production, dwelling environment, wherein contains very many low-temperature heat quantities, can extract recycling fully, should not discard in vain.
Using heat pump technical principle and relevant device thereof, when the user needs heating winter, can extract the low-temperature heat quantity that reclaims wherein municipal sewage as low-temperature heat source, and can also convert thereof into high-grade heat energy (raising temperature), conveying passes to the user and utilizes.When the user needs refrigeration air-conditioner summer, again can be municipal sewage as low-temperature water source (cooling water source), to release heat wherein, reach the purpose of refrigeration air-conditioner for the user.
Municipal sewage is a kind of utilizable water resource of preciousness.But, extracting and using in the process of municipal wastewater flow process, suspension that contains in the sewage and graininess foreign material are very harmful, easily cause equipment such as water pump, heat exchanger, pipeline, valve to stop up, and source pump can not normally be moved.
At present, known equipment of fetching water from sewage does not have good filtering function and backwashing function.
Summary of the invention
In order to overcome the deficiency of prior art and sewage intake equipment, the utility model provides a kind of squirrel-cage intake equipment with preliminary filtering function, promptly can be to tentatively filtering in the sewage intake process, remove the harmful foreign material in the decontaminated water, have the function of under fluid pressure action, its filtration layer being carried out backwash again, the foreign material that are adsorbed on the filtration layer are rinsed out, its simple in structure being suitable for, make and install easily, operational management is convenient.
The technical scheme in the invention for solving the technical problem is: the squirrel-cage intake equipment, its outside is that a kind of shape is as mouse cage shape filtration layer, there is the water intaking screen casing inside, be connected with the sewage intake pipeline, the cross section of the filtration layer of mouse cage shape can be square, rectangle, various ways such as circular pipe shape, mainly by expanded metal lath, stainless steel cloth, Web materials such as nylon wire, single or multiple lift is formed, the skeleton that useful various shaped steel or steel pipe constitute, has certain rigidity and intensity, have decay resistance, have good water permeability (crossing the water-based energy).The squirrel-cage intake equipment can be immersed in the sewage of pipe duct, tentatively filter and extract sewage, the size of the discharge area of its netted filtering deck, with the flow velocity and the ducted water withdrawal of sewage intake of sewage in the pipe duct direct relation is arranged, under the swabbing action of foul water pump, requiring sewage to penetrate the flow velocity of filtration layer from pipe duct should be less than the flow velocity of sewage in pipe duct).The harmful foreign material that stopped by the filtration of mouse cage shape filtration layer in the sewage can in time be impacted by the sewage in the pipe duct and take away, be unlikely long-time absorption and rest on the surface of mouse cage shape filtration layer, influence proceeding of its preliminary filtering function, the sewage intake quantity that influence needs.
The beneficial effects of the utility model are: make, install and use the squirrel-cage intake equipment, in sewer, extract in the sewage, can carry out preliminary filtration treatment to sewage, get rid of harmful foreign material, prevent blocking pipe, valve, water pump, heat exchanger or source pump equipment, it is simple in structure to be suitable for, to make and install easily, and use and management is convenient.
Squirrel-cage sewage intake equipment of the present utility model has preliminary filtering function, also has backwashing function, and it filters and the course of work of backwash, is to be switched mutually and controlled by process pipe and by-pass valve control.Be applicable to extraction and preliminary filtration the to municipal sewage, also be applicable to extraction and filtration to other various fluids, range of application is more extensive.

The specific embodiment
In the squirrel-cage sewage intake equipment structural principle and general assembly drawing shown in Figure 1, intake equipment is mainly by filtration layer (1), and water intaking screen casing (2) and water intake conduit (3) three parts are formed.The squirrel-cage intake equipment should immerse among the sewage of pipe duct; because the swabbing action of foul water pump; intake pipe (3); the inner vacuum that forms of screen casing (2) and cage-shaped structure; sewage in the pipe duct penetrates filtration layer (1); enter cage-shaped structure inside after filtering; the main effect of screen casing (2) is that water intaking is evenly distributed; filtration layer (1) rate of filtration uniformity everywhere; how much are the bore diameter size of screen casing (2) and the quantity in hole; should be according to the length of mouse cage: factors such as water withdrawal be determined by actual conditions; at the boring position of screen casing (2) bag netted filtering material; can play preliminary filtering function equally; when squirrel-cage filtration layer (1) when damaging, the screen casing (2) with netted filtering material can play preliminary filtration protective effect too.This screen casing with netted filtering material also can filter intake equipment as squirrel-cage separately, being connected water intaking separately with water intake conduit (3) uses, equally, the squirrel-cage intake equipment also can not be provided with screen casing (2), directly squirrel-cage filtration (1) is connected with water intake conduit (3), also can filter water intaking uses, but, preferred plan is still by shown in Figure 1, by squirrel-cage filtration (1), screen casing (2) and water intake conduit (3) combine, and sewage intake are filtered have the double insurance effect.
Fig. 2 is screen casing (a 2) constructional drawing, bore diameter wherein, and quantity and mode arranged evenly can be determined voluntarily according to actual conditions.The boring outside should be surrounded by netted filtering material (stainless steel cloth, nylon wire etc.).Tubing processing and fabricatings such as available steel pipe or plastic pipe can use separately.
Fig. 3 is the constructional drawing of mouse cage filtration (1), and the cross section of mouse cage can be multiple shapes such as circular, square, rectangle, and its cross section and profile total length can be determined according to actual conditions.It is all-in-one-piece to be made as a joint, also can make by merogenesis, is assembled into together in pipe duct again, can install and use as the water intaking filter plant separately.
