Abstract
The utility model discloses a back wash type preposed filtering device. The device comprises a water tank, a water pump, a first filtering tank, a second filtering tank and a refined filtering tank, wherein the water pump is connected with an output end of the water tank through a pipeline, the first filtering tank is connected with an output end of the water pump through a pipeline, the second filtering tank is connected with an output end of the first filtering tank through a pipeline, the refined filtering tank is connected with an output end of the an output end of the second filtering tank through a pipeline, control valves are all installed on the first filtering tank and the second filtering tank, and an output end of the water pump is connected with the output ends of the first filtering tank and the second filtering tank through a back wash pipeline. When the absorption capacity of an absorption material located in the filtering tanks is in a saturation state, back washing can be performed, and the absorption material is subjected to purification, so that the absorption capacity of the absorption material is restored, the absorption capacity material can be recycled, and the maintenance cost of water processing is reduced effectively.
Description
Technical field
The utility model relates to the purification treatment technology field, specifically is the preposition filtration unit of a kind of back flush type
Background technology
Continuous improvement along with production, standard of living also improves constantly requirements in water quality, has occurred the more equipment that is exclusively used in the water purifying treatment then.
Most of water purification apparatus all are to adopt sorbing material, isolate the larger particles in the pretreated water, to realize purification effects; Yet the function that existing water purification apparatus does not all possess cleaning can not realize second stage employ; When the adsorptive power of sorbing material reached capacity state, the usefulness of its purifying treatment was had a greatly reduced quality, and whole even device is scrapped; Need to change the self-filtering material, make decontamination process have higher maintenance cost.
The utility model content
To the deficiency of prior art, the purpose of the utility model is intended to provide a kind of back flush type preposition filtration unit, and it can recycle, reduces the cost of water purifying treatment.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The preposition filtration unit of back flush type; Comprise water tank, through pipeline be connected the water tank output terminal water pump, through pipeline be connected the water pump output terminal first hay tank, be connected second hay tank of the first hay tank output terminal, be connected the smart filter tank of the second hay tank output terminal through pipeline through pipeline; On first hay tank and second hay tank valve is installed all, the output terminal of water pump is connected the output terminal of first hay tank and second hay tank through counter-flushing pipeline.
Be disposed with coarse sand filtering layer, fine sand filtering layer, coarse sand filtering layer in first hay tank from top to bottom.
Be disposed with coal quality filtering layer, shell filtering layer, coal quality filtering layer in second hay tank from top to bottom.
The beneficial effect of the utility model is:
When the adsorptive power of the sorbing material that is arranged in hay tank reaches capacity state, can implement back flushing, sorbing material is carried out purifying treatment, thereby recover the adsorptive power of sorbing material, can recycle, effectively reduced the maintenance cost of water treatment,
Description of drawings
Fig. 1 is the structural representation of the preposition filtration unit of a kind of back flush type of the utility model.
Embodiment
Below, in conjunction with accompanying drawing and embodiment, the utility model done further describing:
As shown in Figure 1; Be the preposition filtration unit of a kind of back flush type of the utility model; It comprises water tank 1, through pipeline be connected water tank 1 output terminal water pump 2, through pipeline be connected water pump 2 output terminals first hay tank 3, be connected second hay tank 4 of first hay tank, 3 output terminals, be connected the smart filter tank 5 of second hay tank, 4 output terminals through pipeline through pipeline; Be equipped with on first hay tank 3 on multifunctional control valve 34, second hay tank 4 multifunctional control valve 44 is installed, the output terminal of water pump 2 is connected the output terminal of first hay tank 3 and second hay tank 4 through counter-flushing pipeline 9.
Be disposed with coarse sand filtering layer 31, fine sand filtering layer 32, coarse sand filtering layer 33 in first hay tank 3 from top to bottom.
Be disposed with coal quality filtering layer 41, shell filtering layer 42, coal quality filtering layer 43 in second hay tank 4 from top to bottom.
During work; Treater control multifunctional control valve 34,44 dials to water intake end; Carry out normal water treatment procedure this moment, and after water treatment procedure carried out certain hour, the time relay control multifunctional control valve 34,44 in the treater dialed to the back flushing end; The water that water pump 2 extracts in the water tank 1 is implemented back flushing to first hay tank 3 and second hay tank 4, to purify its two inner filtering material.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
Claims (3)
1. preposition filtration unit of back flush type; Comprise water tank, through pipeline be connected the water tank output terminal water pump, through pipeline be connected the water pump output terminal first hay tank, be connected second hay tank of the first hay tank output terminal, be connected the smart filter tank of the second hay tank output terminal through pipeline through pipeline; It is characterized in that; On first hay tank and second hay tank valve is installed all, the output terminal of water pump is connected the output terminal of first hay tank and second hay tank through counter-flushing pipeline.
