Abstract

The utility model discloses a forced sand setting type centrifugal drip irrigation filter, belonging to the field of facility agriculture. The drip irrigation filter is composed of an upper vertical cylindrical cavity vortex tank, a middle cavity cone separating tank and a lower horizontal cylindrical cavity sand setting tank which are sequentially communicated, wherein a water inlet pipe is arranged in a communicated mode along the direction of the upper tangent of the vortex tank; the inner wall of the separating tank is connected with a raised spiral diversion rib or a spiral diversion trench with an inward concave part, a lower opening of the separating tank and an upper opening of the sand setting tank are communicated through an interface flange plate, the inner walls of the upper and lower openings are respectively connected with vertical diversion plates arranged at a certain interval, and the upper and lower diversion plates are in butt joint oppositely; and the upper port of the vortex tank is connected with a vertical drain pipe, and a lower port of the pipe is arranged in the middle position of the vortex tank. The drip irrigation filter can guide the flow direction of a water body, increase the rotational flow speed of the water body, increase the centrifugal force, forcedly realize the rapid separation of water and sand, strengthen the filtering effect, and reduce the wear degree of tank bodies.

Description

Force the centrifugal drop irrigation filter of sand settling type

Technical field

The centrifugal drop irrigation filter of pressure sand settling type of the present utility model belongs to the industrialized agriculture field, relates in particular to a kind of drip irrigation equipment.

Background technology

Existing desilting formula centrifugal filter, the fine sand in the water body are in the sinking process, because its density is larger, unit mass is less, and subsidence velocity slowly even only transfers not sink in the tank body inward turning, water, husky inferior separating effect, the wearing and tearing aggravation of tank body lower end.

Summary of the invention

The purpose of this utility model is to propose a kind ofly can obviously improve water, husky separation degree, strengthens filter effect, the centrifugal drop irrigation filter of pressure sand settling type of protection tank body.

The purpose of this utility model is achieved in that forces the centrifugal drop irrigation filter of sand settling type to be comprised of the eddy flow tank on top, the knockout drum at middle part and the desilting tank connection of bottom, and the top tangential direction connection of conrotatory stream tank is equiped with water inlet pipe.Inwall at knockout drum is provided with guiding device, and the end opening of knockout drum is communicated with by the flange dish with the suitable for reading of desilting tank, respectively connects spaced vertical deflector on the upper and lower mouthful of inwall, and upper and lower each deflector docks mutually.Eddy flow tank upper port place is connected with vertical outlet pipe, and infratubal port is positioned at the position, middle part of eddy flow tank.

Owing to carry out technique scheme, this drop irrigation filter just can be guided the water body flow direction, accelerates the swirl velocity of water body, increases centrifugal force, forces to realize the quick separation of water, sand, strengthens filter effect, alleviates the tank body degree of wear.

The specific embodiment:

The utility model is not subjected to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.

Embodiment 1:Shown in Fig. 1-5, force the centrifugal drop irrigation filter of sand settling type by the vertical cylindrical cavity eddy flow tank 9 on top, the cavity "conesep" tank 3 at middle part and the Horizontal Cylinder cavity desilting tank of bottom 5 are communicated with and form, the top tangential direction connection of conrotatory stream tank 9 is equiped with water inlet pipe, its outer mouth of pipe is connected with water-in flange dish 2, the adherent helical form water conservancy diversion rib 12 that is connected with protrusion on the inwall of knockout drum 3, the end opening of knockout drum 3 is communicated with by flange dish 4 with the suitable for reading of desilting tank 5, on, respectively connect spaced vertical deflector 11 on the end opening inwall, on, lower each deflector 11 docks mutually.Upper port 1 place of eddy flow tank 9 is connected with vertical outlet pipe 10, and this infratubal port is positioned at the position, middle part of eddy flow tank 9.The one end connection of desilting tank 5 is equiped with sand discharge pipe 6, and pipe cap is arranged on the mouth of pipe, and the other end is communicated with a sand surfing pipe by sand surfing ring flange 8.

During filtration, close the import and export at desilting tank 5 two ends, enter the water body of eddy flow tank 9 from water inlet pipe, form eddy flow along the tank inwall, the silt that is mixed in the water body is sunk to entering knockout drum 3 by preliminary centrifugation, because this tank is cone, the in addition effect of water conservancy diversion rib 12, so that water body eddy flow flow velocity strengthens, centrifugal force obviously strengthens, and the silt that is mixed in the water body is forced to centrifugation, under the water conservancy diversion of knockout drum 3, desilting tank 5 two tank tank mouth deflectors 11, silt sinks to rapidly at the bottom of desilting tank 5 tanks, and the water body of clarification flows into from outlet pipe 10 lower port, flows out through upper port.

Embodiment 2:As shown in Figure 4, have the helical form guiding gutter 13 of indent at the inwall of knockout drum 3, all the other all are same as embodiment 1.

Regularly open the import and export at desilting tank 5 two ends, in the tank that can discharge water, the silt that will accumulate is discharged from sand discharge pipe 6.

Above technical characterictic has consisted of most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease according to actual needs inessential technical characterictic, satisfies the needs of different situations.
