Description

A kind of automatic anti-cleaning device

Technical field

The utility model relates to a kind of automatic anti-cleaning device, and it mainly is applicable to sewage disposal devices such as smelting iron and steel factory, electric power, petrochemical industry, municipal works, food processing factory, papermaking, rubber leather manufactory.

Background technology

Automatically instead clean the main three kinds of cleaning ways that adopt at present in the wastewater treatment in China equipment: clean by electric control valve is counter; Pneumatic control valve is counter to be cleaned; Hydraulic valve is counter to be cleaned.Their common ground all is to utilize valve to finish by other power, and so not only equipment operation needs the energy, and valve works long hours and can damage, thereby influences the operate as normal of sewage apparatus.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of automatic anti-cleaning device, and it utilizes siphon principle to carry out anti-cleaning the automatically.This device has not only been saved the energy, but also has prolonged the service life of filter plant.

A kind of automatic anti-cleaning device of the utility model, it is characterized in that: it comprises liquid reserve tank, water inlet pipe, filtrate pond, backwash outlet pipe, siphon destructive bucket, siphon guiding tube, the siphon person in charge, exhaust outlet, seal groove; The upper end of water inlet pipe be welded on liquid reserve tank below, the lower end puts in the filtrate pond; The backwash outlet pipe is inverted L type pipe, its lower end be welded on the filtrate pond above, high horizontal ends is welded on the side that siphon is responsible for, the siphon guiding tube vertically passes from the horizontal segment of backwash outlet pipe, it is welded with the siphon destructive bucket bottom, and the siphon destructive bucket is in the top in filtrate pond, the upper end of siphon guiding tube be welded on that siphon is responsible for above, the lower end that siphon is responsible for extend in the seal groove, and water is equipped with in the seal groove the inside; Exhaust outlet is welded on the side that siphon is responsible for.

When using device of the present utility model, sewage in the liquid reserve tank flows in the filtrate pond that filtrate is housed by water inlet pipe and filters, prolongation along with filtration time, to tackle many granule foreigns above the filtrate, clean water after the filtration is collected in the water cap in the filtrate pond, progressively the sewage of Sheng Gaoing flows in the backwash outlet pipe, a part of water in the backwash outlet pipe enters into the siphon destructive bucket, another part water enters into siphon and is responsible for by exhaust outlet the air discharge in the siphon person in charge, at this moment sewage will enter in the siphon person in charge by the siphon guiding tube, at this moment the pressure in the pressure in the filtrate pond is responsible for much larger than siphon, therefore the water in the filtrate pond can enter into the siphon person in charge soon, the anti-cleaning automatically carried out in realization, and anti-cleaning will all clean the granule foreign on the filtrate walk.When the pressure in siphon is responsible for equated with the pressure in the filtrate pond, backwash process finished.At this moment, the water level in the siphon destructive bucket equates with water level in the siphon host and guest.

The advantage of this new type auto anti-cleaning device is: 1, it utilizes siphon principle to realize anti-cleaning the automatically, does not need other power, thereby has saved the energy; 2, do not need to use valve in the device, the operate as normal that valve damages influences sewage apparatus can not take place, prolonged the service life of filter plant.

The specific embodiment

As can be seen from Figure 1, this novel a kind of automatic anti-cleaning device, it comprises liquid reserve tank 1, water inlet pipe 2, filtrate pond 3, backwash outlet pipe 4, siphon destructive bucket 5, siphon guiding tube 6, the siphon person in charge 8, exhaust outlet 9, seal groove 10; The upper end of water inlet pipe 2 be welded on liquid reserve tank 1 below, the lower end puts in the filtrate pond 3; Backwash outlet pipe 4 is inverted L type pipe, its lower end be welded on filtrate pond 3 above, high horizontal ends is welded on siphon and is responsible for 8 side, siphon guiding tube 6 vertically passes from the horizontal segment of backwash outlet pipe 4, it is welded with siphon destructive bucket 5 bottom, and siphon destructive bucket 5 is in the top in filtrate pond 3, the upper end of siphon guiding tube 6 be welded on siphon be responsible for 8 above, the siphon person in charge 8 lower end extend in the seal groove 10, and water is equipped with in seal groove 10 the insides; Exhaust outlet 9 is welded on siphon and is responsible for 8 side.Wherein, the water cap 11 that the filtrate pond is 3 li is clean waters of collecting after filtering, and filtrate 12 is filtered source.

Wherein, exhaust outlet 9 is welded on siphon and is responsible for 8 side, is conducive to exhaust; Water is equipped with in seal groove 10 the insides, mainly is that the sealing siphon is responsible for 8, guarantees that the siphon person in charge 8 forms vacuum.

The maintenance of equipment for convenience, as this novel a kind of improved procedure, device comprises that also access hole 7, access hole 7 are welded on siphon and are responsible for the top of 8.

In device of the present utility model, sewage in the liquid reserve tank 1 flows to by water inlet pipe 2 in the filtrate pond 3 that filtrate 12 is housed and filters, prolongation along with filtration time, to tackle many granule foreigns above the filtrate 12, water will progressively raise and flow in backwash outlet pipe 4 and the siphon destructive bucket 5, water flows to siphon through siphon guiding tube 6 and is responsible for 8 then, the air that exhaust outlet 9 is responsible for siphon in 8 comes seal groove 10 outsides, 8 inside are responsible in siphon will form " vacuum ", utilizes pressure differential can carry out anti-cleaning the automatically.Anti-cleaning will all clean the granule foreign on the filtrate 12 walk, and liquid level will drop to below the siphon destructive bucket, has finished backwash process one time.

This device utilizes siphon principle to carry out automatically anti-the cleaning: siphon principle mainly is that liquid intermolecular attraction and potential energy difference cause, and namely utilizes water column pressure poor, flows to lower again after making liter waterborne.Because the mouth of pipe water surface bears different atmospheric pressures, while water can by pressure big to flow to pressure little, the atmospheric pressure up to both sides equates that the water surface in the container becomes identical height, water will stop to flow.

This is novel to utilize self waterpower to carry out automatic back-washing, not only energy-conserving and environment-protective, and saved a lot of valves, and reduced the operating cost of equipment, improved the performance of equipment, be modern industry sewage disposal novel device.It is the important breakthrough that China's water treatment is filtered, and plays a positive role for alleviating China's water scarcity situation, and the timely use of this equipment brings huge economy, society and environmental benefit will for country and business unit.
