A first-level sand discharge port is arranged at the lower end of the taper barrel, an overflow partition is enclosed in the casing, an overflow inlet communicating with the taper barrel and an overflow outlet communicating with a portion between the casing and the taper barrel of a sand setting chamber are opened on the overflow partition, an overflow pipe extending downwards is connected to the overflow outlet, a water outlet is arranged on an upper portion of the casing section corresponding to the sand setting chamber, a second-level sand discharge port connected with the bottom of the sand setting chamber is further opened on the casing, and a second-level sand discharge valve is arranged at the second-level sand discharge port. Two levels of filtering are adopted for the filter, the first-level filtering is also the centrifugal filtering, the second-level filtering is to deposit gravel particles at the bottom of the sand setting chamber through a gravity mode, therefore inconvenience of periodic cleaning of filter layers caused by the fact that the filter layers are used for the filtering is avoided, additionally, the structure is simple, and the overall cost is reduced.
Description
Technical field
The utility model relates to a kind of sedimeter, is specifically related to a kind of secondary sediment outflow filter.
Background technology
In agricultural irrigation and some industrial process waters processes; Owing to all contain the sandstone particle in the water such as the well water that uses, river, generally all to filter through filter, traditional filter is generally grade one filter; Like centrifugal type filter, net type filter; The shortcoming of centrifugal type filter is: easy filtration is fallen bigger sandstone particle, and less sandstone particle also can be along with current be attached in the water, and filter effect is not good; Net type filter must regularly be cleared up filter screen, and is cumbersome, uses inconvenient.
Chinese patent CN2451211Y discloses a kind of filter, and this filter comprises housing, is provided with the awl tube in the housing; On the sidewall of awl tube, offer the water inlet of arranging along awl tube tangential direction, the water inlet is connected with water inlet pipe, and current are got in the awl tube by the inner conical surface tangential direction of water inlet pipe along the awl tube; Compelled do gyration; Under the acting in conjunction of centrifugal force and gravity, the part sandstone particle in the current to the bottom that is lowered into the awl tube, is communicated with sediment outflow pipe in the bottom of awl tube along the spiral inner wall of awl tube; The end of sediment outflow pipe stretches out housing; Sink to the sandstone particle of awl tube bottom and regularly discharged by the sediment outflow pipe, be communicated with the shower of a horizontally set at the top of awl tube, undischarged sandstone particle overflows shower with current and gets into the part between housing and the awl tube; Between inner walls and awl drum outer wall, be provided with one deck filter course, the current that overflowed by shower filter through filter course, and the drainpipe that finally is communicated with by housing bottom is discharged.This filter adopts the cascade filtration structure; One-level is filtered through the centrifugation pond and is adopted centrifugation to filter; Sandstone particle that will be bigger is discharged by the sediment outflow pipe, and cascade filtration adopts filter course to filter, and the less sandstone particle of undischarged part was stayed on the filter course during the first order was filtered.Though the filter of this structure has adopted the mode of cascade filtration; But still exist and need the problem that regularly clean filter course; In addition, because the bottom of awl tube directly is communicated with the sediment outflow pipe, the big and less sandstone particle of part during one-level is filtered directly is deposited on the bottom of awl tube; Wherein a part of less sandstone particle is flushed to awl tube top by the current of spiral easily, has increased the burden of filter course.
The utility model content
The purpose of the utility model provides a kind of sediment outflow filter, adopts filter course to filter in order to the cascade filtration that solves existing secondary filter, the inconvenient problem with use that needs regular cleaning and filtering layer to cause.
The utility model adopts following technical scheme: a kind of sediment outflow filter; Comprise housing and be arranged on the up big and down small awl tube in the housing; Offering towards an awl water inlet that the inner conical surface tangential direction is provided with of awl tube by top; The lower end of awl tube is provided with the one-level sand removing hole, and one-level sand removing hole place is provided with the one-level sand flash valve that is used to control one-level sand removing hole break-make, offers delivery port on the said housing; Envelope is provided with the housing inner chamber is divided into the spilling water chamber arranged up and down and the spilling water dividing plate of sand setting chamber in the said housing; Offer on the spilling water dividing plate and bore a spilling water import that tube upper end is communicated with, export with the partially communicating spilling water between housing and awl tube of said sand setting chamber, said spilling water exit is connected with to the overflow pipe that extends below, said delivery port be arranged on said sand setting chamber corresponding shell section by top; Also offer the secondary sand removing hole with said sand setting chamber bottom connection on the said housing, secondary sand removing hole place is provided with the secondary sand flash valve that is used to control secondary sand removing hole break-make.
Said delivery port be arranged at housing away from said overflow pipe position.
In the said housing also envelope be provided with said sand setting chamber be divided into up and down the secondary sand setting chamber arranged and the sand setting dividing plate of one-level sand setting chamber; It is indoor that said awl tube is arranged on the secondary sand setting; Offer the spigot that is communicated with said awl tube lower end on the sand setting dividing plate, said one-level sand removing hole is arranged on the lower end of said one-level sand setting chamber corresponding shell section.
The top of leaning on of said housing also offers exhaust outlet, and exhaust ports is provided with the air bleeding valve that is used to control the exhaust outlet break-make.
Adopt the sediment outflow filter of said structure; Because envelope is provided with the housing inner chamber is divided into the spilling water chamber arranged up and down and the spilling water dividing plate of expansion chamber in the housing; Offer the outlet of spilling water import and spilling water on the spilling water dividing plate; Get in the awl tube part sandstone particle with current by the spilling water import get into spilling water indoor after, arrive bottom, sand setting chamber by the spilling water outlet through overflow pipe again, the sandstone particle in the effect deposit of gravity in bottom, sand setting chamber; Under the effect of secondary sand flash valve, regularly discharge simultaneously by the secondary sand removing hole; Delivery port is arranged on the epimere part of sand setting chamber corresponding shell section, and away from sand setting chamber bottom, the effect of overflow pipe is the current that spilling water is indoor by drawing near sand setting chamber bottom position, prevents that the sandstone particle from being discharged by delivery port.The filter of this structure has also adopted cascade filtration, and wherein one-level is filtered and is similarly centrifugal filtration, and cascade filtration adopts the gravity mode to make the sandstone particle deposition in bottom, sand setting chamber; And discharge by the secondary sand removing hole; Therefore the effect that has twice filtration equally, has been avoided using filter course to filter the inconvenience of the regular cleaning and filtering layer of needs that causes; And simple in structure, reduced whole cost.
