Abstract
The utility model discloses a centrifugal filter which comprises a water inlet pipe, an overflowing pipe, a flow guide barrel with a conical outline, a barrel body with a top cover and a desilting box, wherein the water inlet pipe is arranged on the barrel body along the tangential direction of the barrel body, the desilting box is communicated with the bottom of the barrel body, the overflowing pipe is arranged above the top cover of the barrel body, the flow guide barrel is arranged under the top cover of the barrel body, and the flow guide barrel is communicated and connected with the overflowing pipe. The incoming flow of the water inlet pipe flows into the filter along the tangential direction of the inner wall at the upper part of the cylindrical barrel body, so that the incoming flow downwards and spirally flows around the outer wall surface of the conical barrel of the flow guide barrel by the means that the diameter is gradually enlarged, and the fluid generates a momentum which rotates around the axes of the barrel body to generate a centrifugal force and separate out solid particles in the fluid; and the short circuit flow is eliminated, and the problem that the separation efficiency is reduced since the short circuit flow generated by the incoming flow around the flow guide barrel directly enters into the flow guide barrel is solved.
Description
Technical field
The utility model relates to agricultural irrigation machinery field, is specifically related to a kind of centrifugal type filter.
Background technology
Centrifugal type filter uses very universal in agricultural irrigation.As the patent No. is 98240446.8 patent, this patent disclosure a kind of cartridge filter top guide shell is installed, loam cake is installed in the guide shell upper end, a side is provided with delivery port, delivery port is provided with pressure tapping; The combination filter of the screen pack of tubular is installed in the guide shell.But in the prior art of this patent disclosure, short-circuit flow is that the principal character that fluid flows in this filter one of flows, and is to cause the separator overflow pipe to run one of key factor that thickness mixes in thick, the separated sandstone.In existing sandstone filter, short-circuit flow certainly exists, and this is that structure by present sandstone filter guide shell is determined; The version of guide shell not only influences the separative efficiency of sandstone filter, also influences the flow size and the leaving energy loss of filter.The version of this explanation guide shell directly influences the overall performance of sandstone filter.
Short-circuit flow comprises that the top changes and covers short-circuit flow and sidewall short-circuit flow in the existing centrifugal sandstone filter.When concentration of solid particles is moderate in the fluid, an eddy current that suppresses short-circuit flow can appear under top cover, and this is favourable to the cyclone separating property.The oppose side wall short-circuit flow, owing to have radial pulsation in the sidewall boundary layer, causing solid particle in the short-circuit flow to break away from from all short-circuit flows with a part of short-circuit flow comes, directly enter guide shell, make the particle of the greater particle size that appearance should not occur in the overflow, thereby the separative efficiency of filter is descended.Adopt Hydrodynamics Theory that its flow field is analyzed, the result shows, near the sidewall short-circuit flow that guide shell, occurs, and a part wherein directly enters guide shell, and often contains the solid particle of big concentration in the sidewall short-circuit flow.Experiment test has also confirmed this point.Therefore, how effectively eliminating or reduce the sidewall short-circuit flow, is the valid approach that improves centrifugal sandstone filter separative efficiency.
