Description

Combined type funnel rotational flow sand sinking device

Technical field

The utility model relates to the device that the silt particle in a kind of water that silt content is big separates.

Background technology

In the prior art, irrigation system and draw field irrigation such as yellow irrigation and all relate to sand removal.Because the silt content of Huanghe water is big, generally reaches 16kg/m3, and is bigger at the wet season silt content; Much draw yellow irrigation system bringing in a large number owing to silt particle, easy precipitation depression is filled and led up already, does not bring into play effect at all, and Huanghe water directly enters canal system, farmland, cause silt particle in channel, to deposit, the farmland is also covered by silt particle, and the silt particle that channel goes out clearly is deposited in the channel both sides, accounts for to press a large amount of farmlands, meet windy day, sandy soil fly upward, and desilting is carried out repeatedly, draw the yellow irrigated area people to the locality and bring heavy burden.Because silt particle is gone into canal, gone into the field with water, desilting can only be distributed hand labor, and how wide the canal system scope have, and how wide the silt particle scope of piling up just have, and whole irrigation district all is among the harm of silt sand.

Technology contents

The purpose of this utility model is, designs combined type funnel rotational flow sand sinking device, can be used for drawing that stem supplies water in the yellow engineering, before entering channel, concentrate and force sand removal, the silt particle good separating effect, unimpeded to guarantee channel, be convenient to the silt particle that the silt particle mechanical transport focuses on deposition.

The technical solution of the utility model is, described combined type rotational flow sand sinking device has uncovered exterior cylinder, this exterior cylinder bottom is that the feed end of a taper sand trap cavity and its bottom and screw conveyer joins, its design feature is, inner cylinder body is arranged in described exterior cylinder and places on the bracing frame at its lower port position, there is annular groove to link to each other between described inner cylinder body and the exterior cylinder with described taper sand trap cavity, inner cylinder body bottom is provided with a plurality of funnel holes and its top is provided with the orifice plate that is lower than this inner cylinder body upper port, the peripheral equally distributed funnel hole in a plurality of edges is arranged on this orifice plate, the upper port of described funnel hole is greater than lower port, is communicated with and is positioned at the middle part of inner cylinder body according to the water inlet pipe of the tangential direction setting of inner cylinder body horizontal cross-section through the barrel of exterior cylinder and inner cylinder body and its delivery port and inner cylinder body inner chamber, be provided with in the middle part of the inner cylinder body in bottom it and between the orifice plate and horizontal cross-section and be

The wing plate of shape, exterior cylinder upper outside have the cannelure of band discharge outlet.

Below the utility model made further specify.

By Fig. 1 to Fig. 3 as can be known, the utility model has uncovered exterior cylinder 1, this exterior cylinder 1 bottom is that the feed end of a taper sand trap cavity 6 and its bottom and screw conveyer 7 joins, its design feature is, inner cylinder body 2 is positioned at described exterior cylinder 1 and places on the bracing frame frame 11 at its lower port position, there is annular groove 10 to be communicated with between circle 1 and the exterior cylinder 2 in described with described taper sand trap cavity 6, inner cylinder body 2 bottoms are provided with a plurality of funnel holes 5 and its top is provided with the orifice plate 8 that is lower than these inner cylinder body 2 upper port, the peripheral equally distributed funnel hole 51 in a plurality of edges is arranged on this orifice plate 8, described

funnel hole

5 and 51 upper port are greater than lower port, be communicated with and be positioned at the middle part of inner cylinder body 2 according to the water inlet pipe 3 of the tangential direction setting of inner cylinder body 2 horizontal cross-sections through the barrel of exterior cylinders 1 and inner cylinder body 2 and its delivery port and inner cylinder body 2 inner chambers, inner cylinder body 2 middle parts are provided with in bottom it and between the orifice plate 8 and horizontal cross-section and are

The wing plate 4 of shape, exterior cylinder 1 upper outside have the cannelure 9 of band discharge outlet.

Design of the present utility model and operation principle are, this device can be placed and draw the stem that Huang is gone into canal, when the current that have silt particle enter in the inner cylinder body 1 through water pipe 3, produce identical and the operating condition that linear velocity is different of angular speed owing to the described tangent position setting of water inlet pipe 3 makes the mixture of water that has just entered and the water that is introduced into, promptly current then focus on the eddy flow middle part at the outside of eddy flow sand grains; This is because sand grains proportion is bigger than water, will rotate synchronously under the condition that kinetic energy evenly transmits, its sand grains must reduce linear velocity and concentrate to the middle part, and the middle part has one to revolve direction downstream Type column wing plate, between wing plate, produce the upright post type eddy current, the kinetic energy of Xiao Haoing further, under the gravity effect, sand grains sinks to sand trap cavity 6 to sinking by funnel hole 5, and the setting owing to the bracing frame 11 that plays spacer function makes the bottom water body not produce eddy flow again, sand setting is constantly promoted the back by screw conveyer 7 and extracts out, concentrates and transports.The outer field water of eddy flow is then upwards gushed out by the funnel hole 51 of orifice plate 8, and this moment, water velocity reduced owing to aisle spare enlarges, and current cover outer cylinder body 1 upper port again, flow into cannelure 9, are sent by its discharge outlet; After current were gushed out by funnel hole 51, even also have a small amount of silt particle, when covering exterior cylinder 1, because the flow velocity of water is die-offed, sand grains was blocked in the exterior cylinder 1, falls into annular groove 10, sinks to sand trap cavity 6.

As known from the above, the utility model is a combined type funnel rotational flow sand sinking device, is a kind of continuous operation device of forcing to concentrate water inlet, separating silt particle, water supply.

Have that silt particle good separating effect, the silt particle that can focus on deposition, apparatus structure are simple, the characteristics of reliable operation.
