Technical field

The utility model relates to technical field of sewage, relates to a kind of efficient apparatus for physical Chemical treating of simple and easy, quick solid-liquid separation especially.

Background technology

At present; In some Industrial Wastewater Treatment engineerings, often need make colloidal solid, pollution substance in the waste water form the easy to handle flco, then through deposition or air-floating apparatus toward dosing coagulant, coagulant aids in the waste water; These mud (floating) slag is removed from water, waste water is purified.Mostly the physical reaction that often has behind the coagulating is the settling tank or the air flotation pool of function singleness.The settling tank of prior art or air flotation pool have following drawback: 1, depositing technology can not precipitate down whole flcos, and small and light flco floats on the water surface, and top layer water surface scum silica frost is easy-clear not; 2, air-float technology can not be with whole flco dissolved air flotations, and big and closely knit flco is deposited at the bottom of the pond, the unfavorable removing of device bottom deposition slag; 3, existing inclined tube floating pond water cleaning systems is used better in water treatment system, but in Industrial Wastewater Treatment, is existed inclined tube to adhere to greasy dirt easily, adheres to flco, causes inclined tube to stop up, and has a strong impact on technology and normally moves, and effluent quality is relatively poor.

The utility model content

The purpose of the utility model is to overcome the defective of prior art; Solve the scum silica frost of fast, efficiently removing coagulating and producing, the problem of body refuse, disclose a kind of equipment for separating liquid from solid that efficiently drifts along, comprising: reaction tank; Its set inside has scum silica frost to isolate inner core; Said scum silica frost is isolated the inner core set inside has the water conservancy diversion reaction tube, and said reaction tank bottom is provided with shore pipe, and the top of said reaction tank is provided with skimming system, slag collection system and outlet system; Air dissolved pump, it is delivered to dissolved air water through Gas dissolving pipe the bottom of said water conservancy diversion reaction tube; Water inlet pipe, it is communicated with at the sidewall of said reaction tank and is communicated to the bottom of said water conservancy diversion reaction tube.

Preferably, the equipment for separating liquid from solid that efficiently drifts along of the utility model, said outlet system comprise around going out water channel and effluent weir on the sidewall that is arranged on said reaction tank.

Preferably, the equipment for separating liquid from solid that efficiently drifts along of the utility model, said shore pipe are perforated pipe, and said perforated pipe has the oblique down interleaved oral pore of 45 degree, and the aperture is 25mm, and pitch of holes is 150mm.

Preferably, the equipment for separating liquid from solid that efficiently drifts along of the utility model, said shore pipe is positioned at the bottom of said water inlet pipe.

Preferably, the equipment for separating liquid from solid that efficiently drifts along of the utility model, said Gas dissolving pipe is positioned at the top of said water inlet pipe.

Preferably, the equipment for separating liquid from solid that efficiently drifts along of the utility model, the bottom of said reaction tank is provided with the bucket of collecting heavy mud.

The beneficial effect of the utility model is: 1, this device has adopted the molten gas mode of air dissolved pump, has saved air compressor machine and pressure air-dissolving tank, compactness simple for structure; Can effectively discharge body refuse; Can effectively remove the scum silica frost in the water again, processing efficiency is high, and floor space is few, construction cost is low; 2, this device combines the constructional feature of airfloat equipment and width of cloth flow settling pond, and the optimizing equipment form realizes carrying out simultaneously the isolating purpose of mud-water separation and body refuse, saves to take up an area of, and cost is low, running cost is low; 3, this device electromechanical equipment is few, and the maintenance of the equipment amount is few, and is easy and simple to handle, and stable and reliable operation has less energy-consumption, advantage cheaply; 4, device is stable, and the suspended substance of water outlet reduces obviously, and water outlet is effective.

Description of drawings

Fig. 1 is a sectional view of the structure of the utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed description, can implement according to this with reference to the specification sheets literal to make those skilled in the art.

As shown in Figure 1; A kind of equipment for separating liquid from solid that efficiently drifts along of the utility model; Comprise: reaction tank 11, its set inside have scum silica frost to isolate inner core 9, and said scum silica frost is isolated inner core 9 set inside has water conservancy diversion reaction tube 8; Said reaction tank 11 bottoms are provided with shore pipe 2, and the top of said reaction tank 11 is provided with skimming system 6, slag collection system 7 and outlet system 12; Air dissolved pump 5, it is delivered to dissolved air water through Gas dissolving pipe 10 bottom of said water conservancy diversion reaction tube 8; Water inlet pipe 1, it is communicated with at the sidewall of said reaction tank 11 and is communicated to the bottom of said water conservancy diversion reaction tube 8.

The equipment for separating liquid from solid that efficiently drifts along of the utility model, said outlet system 12 comprise around going out water channel 3 and effluent weir 4 on the sidewall that is arranged on said reaction tank 11.

The equipment for separating liquid from solid that efficiently drifts along of the utility model, said shore pipe 2 is a perforated pipe, and said perforated pipe has the oblique down interleaved oral pore of 45 degree, and the aperture is 25mm, and pitch of holes is 150mm.

The equipment for separating liquid from solid that efficiently drifts along of the utility model, said shore pipe 2 is positioned at the bottom of said water inlet pipe 1.
