The invention discloses a sand filter tank with sand washing and filtering functions.The sand filter tank comprises a tank body, a sand bed is arranged at the bottom inside the tank body, a water-sand separation device is arranged on the upper portion inside the tank body, the tank body is provided with a water inlet pipeline leading to the sand bed inside the tank body, the tank body is internally provided with an air-lift pipe, the lower portion of the air-lift pipe extends into the sand bed, the upper portion of the air-life pipe is communicated with the water-sand separation device, a water outlet pipeline and a sand washing water outlet pipeline are connected to the water-sand separation device, and the water-sand separation device is provided with a sand discharging channel which separates sand and sends the sand to the bottom inside the tank body.According to the sand filter tank with the sand washing and filtering functions, filtration of sewage and automatic cleaning and blending of the sand can be achieved, and a lot of manpower and material resources are saved, the structure is simple, the cost is low, operation is convenient, and the energy is saved.
Description
[technical field]
The present invention relates to a kind of sandfiltration pot with washed-out sand, filtering function.
[background field]
Along with the improvement of people's life, sewage also gets more and more, such as sanitary sewage, trade effluent etc..And sewage disposal is the environment-friendly engineering that current many cities, factory etc. are required for doing in environmental protection process.
For some techniques needing to use sandfiltration pot in sewage disposal process, existing sandfiltration pot is all fairly simple, but all without being equipped with the function cleaning sand, accumulation over time can cause that filter effect declines, sand is more and more black, more and more dirtier, do not have filter effect, on the contrary water is caused secondary pollution.
[summary of the invention]
It is an object of the invention to overcome the deficiencies in the prior art part, it is provided that a kind of filtration realizing sewage and sand automatically clean allotment, simple in construction, cost is low, easy to operate, saves the medicine energy, saving substantial amounts of manpower and materials, the sandfiltration pot with washed-out sand, filtering function of sand is changed in automatic washed-out sand.
The object of the present invention is achieved like this:
A kind of sandfiltration pot with washed-out sand, filtering function, it is characterized in that it includes tank body, described tank body inner bottom part is provided with casting bed, tank body internal upper part is provided with water and sand separating device, tank body is provided with the inlet channel being passed in tank body casting bed, stripping tube it is additionally provided with in tank body, the bottom of stripping tube extend in casting bed, the top of stripping tube communicates with water and sand separating device, water and sand separating device is connected to outlet conduit and sand-washing water outlet conduit, and described water and sand separating device is additionally provided with the lower husky passage of feeding tank body inner bottom part after being separated by sand.
A kind of sandfiltration pot with washed-out sand, filtering function described above, it is characterised in that described inlet channel bottom is provided with water-locator, water-locator is transverse slat structure.
A kind of sandfiltration pot with washed-out sand, filtering function described above, it is characterised in that described water-locator is arranged below reflection base cone, and reflection base cone is triangle.
A kind of sandfiltration pot with washed-out sand, filtering function described above, it is characterized in that described water and sand separating device includes Seperating box, the bottom of Seperating box is connected to separation pipe, the top of stripping tube extend in Seperating box through separating pipe, lower husky passage is arranged on and separates the side of stripping tube in pipe, outlet conduit is connected to the top of Seperating box, and sand-washing water outlet conduit is connected to the bottom of Seperating box.
A kind of sandfiltration pot with washed-out sand, filtering function described above, it is characterised in that the separation tube inlet side in described Seperating box is provided with dividing plate.
A kind of sandfiltration pot with washed-out sand, filtering function described above, it is characterised in that described tank body lower part is bullet shape.
The present invention enters the sand in the sewage of tank body under gravity, sinks to device casting bed top, it is achieved that sand lifting from bottom to top.This device can the reality filtration of sewage and sand automatically clean allotment, save substantial amounts of manpower and materials.What can realize the filtration of sewage and sand cleans allotment, simple in construction automatically, and cost is low, easy to operate, saves the medicine energy.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the present invention.
[detailed description of the invention]
A kind of sandfiltration pot with washed-out sand, filtering function, it includes tank body 1, described tank body 1 inner bottom part is provided with casting bed 2, tank body 1 internal upper part is provided with water and sand separating device 3, tank body 1 is provided with the inlet channel 4 being passed into casting bed in tank body 1, stripping tube 5 it is additionally provided with in tank body 1, the bottom of stripping tube 5 extend in casting bed 2, the top of stripping tube 5 communicates with water and sand separating device 3, water and sand separating device 3 is connected to outlet conduit 6 and sand-washing water outlet conduit 7, and described water and sand separating device 3 is additionally provided with the lower husky passage 8 of feeding tank body inner bottom part after being separated by sand.
Inlet channel bottom is provided with water-locator 9, and water-locator 9 is transverse slat structure.
Water-locator is arranged below reflection base cone 10, and reflection base cone 10 is triangle, and upward, other two angles are parallel at one of them angle.
Water and sand separating device 3 includes Seperating box 31, the bottom of Seperating box 31 is connected to separation pipe 32, the top of stripping tube 5 extend in Seperating box 31 through separating pipe 32, lower husky passage 8 is arranged on and separates the side of stripping tube 5 in pipe, outlet conduit 6 is connected to the top of Seperating box 31, sand-washing water outlet conduit 7 is connected to the bottom of Seperating box 31, and the separation tube inlet side in Seperating box 31 is provided with dividing plate 33.
Tank body 1 bottom of the present invention is bullet shape.
The work of the present invention former enter be: sewage enters the bottom of the casting bed 2 of tank body 1 bottom by inlet channel 4 and water-locator 9, water sends into tank body 1 bottom, by the process of casting bed 2 is cleaned when flowing up again, the impurity such as float are stayed in casting bed 2, and filtrate water outlet above tank body 1 is discharged.While current flow up, casting bed moves down continuously, under the effect of stripping tube 5, the combination of three, aqueous vapor sand,, float is separated by strong rubbing action with sand bottom tank body 1 by stripping tube 5 upwardly, discharges at stripping tube 5 top, filthy water is discharged by sand-washing water outlet conduit 7, and sand returns to casting bed by lower husky passage 8.So automatically iterative cycles, not only achieves water and walks water channel, Sha Zousha road, has more reached automatic washed-out sand and has changed the function that sand filters.
