To the concern of every country, containing sand excessively, water quality inferiority seriously governs the development of regional economy to some areas current.How to have
Imitate the silt in separated flow, the focus as research.In the prior art, it is many that silt is settled using settling tank, exist worked
Journey is discontinuous, settling tank remove sand difficulty the problem of, part sedimentation device is slowed down using diffusion, and grid slows down, but because being used alone,
Slowing effect is limited, it is impossible to reach purpose of preferably removing sand.
The A of Chinese patent literature CN 103463838 disclose a kind of sewage treatment grit chamber, including horn-like sedimentation basin,
Grille strip, conveying worm, deposition groove, siphon pipe, grit water separator and flusher, the delivery port and current of the setting pot
Direction it is identical, easily the silt in setting pot is carried away, effect of settling reduction.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of grating type desilting device, solves current some areas
Current are containing husky excessive, the ropy problem of DRINKING WATER.
In order to solve the above technical problems, the technical scheme that the utility model is used is：A kind of grating type desilting device,
Including water inlet, settling pit and delivery port, water inlet is calibre-changeable, and the big one end of water inlet bore connects with settling pit
Connect, grid is installed in settling pit, settling pit bottom angled, the relatively low side of settling pit is provided with sand surfing groove, the settling pit
Higher side is equipped with overflow plate, and overflow plate connection Rinsing Area, Rinsing Area is connected with delivery port.
It is preferred that scheme in, the overflow plate is stepped, and one end close to water inlet is high.
It is preferred that scheme in, the settling pit bottom angled angle be 30 °.
It is preferred that scheme in, the grid is semi-cylindrical form or is the screen with hole.
It is preferred that scheme in, the grid quantity be 3~8.
It is preferred that scheme in, the grid uses stainless steel material, and grid is riveted with settling pit.
It is preferred that scheme in, the sand surfing groove be circular arc.
It is preferred that scheme in, the sand surfing groove is connected with sand discharge apparatus.
Further, the sand discharge apparatus is sediment ejection opening and valve, and the sand surfing groove is connected by valve with sediment ejection opening.
A kind of grating type desilting device that the utility model is provided, during by using said structure, the current containing silt
Settling pit is entered by water inlet, by the deceleration of diffusion region and grid, the silt in current is settled, and water velocity is lower,
Current to take husky ability weaker.The certain angle of settling pit bottom angled, sand surfing groove is located at lower position, work of the silt in gravity
Moved with the lower sand surfing groove to settling pit, silt final settlement is in sand surfing groove, and clear water flows into Rinsing Area by overflow plate, pass through row
The mouth of a river is discharged, and reaches the purpose of separation of sediment.It is preferred that scheme in, overflow plate is stepped, away from water inlet one end it is relatively low,
In the presence of grid, one end water speed away from water inlet is relatively low, and current carrying quantity of sand and mud is less, height of the overflow plate in this one end
Degree is relatively low, is conducive to clear water to overflow.When settling pit bottom angled angle is 30 °, silt can be made to assemble well to sand surfing groove.
Current reduction of speed is carried out using multiple grids, the purpose of multi-stage speed-reducing can be played.Sand surfing groove is connected with sand discharge apparatus, it can be ensured that
Desilting device is normally run.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model.
Fig. 2 is sectional view of the utility model along A-A.
Fig. 3 is sectional view of the utility model along B-B.
In figure：Water inlet 1, settling pit 2, delivery port 3, grid 4, overflow plate 5, Rinsing Area 6, sand surfing groove 7, sand discharge apparatus 8,
Sediment ejection opening 81, valve 82.
Embodiment
In such as Fig. 1 ~ 2, a kind of grating type desilting device, including water inlet 1, settling pit 2 and delivery port 3, water inlet 1 is change
Bore, sectional dimension gradually increases, and specific size is determined by water flow, and the material of water inlet 1 is concrete.The water inlet 1
The big one end of bore is connected with settling pit 2, and grid 4 is provided with the settling pit 2, and the quantity of grid is set to 7, grid 4
Using stainless steel material, riveted with settling pit 2.The bottom angled of settling pit 2, angle of inclination is set to 30 °, settling pit 2 it is low one
Side is provided with sand surfing groove 7, and sand surfing groove 7 is circular arc, and the high side of settling pit 2 is equipped with overflow plate 7, and overflow plate 5 connects Rinsing Area 6,
