Description
Technical field
The utility model relates to hydraulic engineering, relates in particular to a kind of filter being applicable to hydraulic engineering.
Background technology
Hydraulic engineering is the general name in order to the every engineering construction controlling, utilize and protect the water resources and environment on earth's surface and underground to build.Hydraulic engineering is the engineering that elimination water damage and exploitation water resource are built, and is divided into flood control works, farmland water conservancy works, hydraulic power project, navigation channel and port engineering, water supply and drainage system, environmental bydraulic engineering engineering, sea-beach reclamation engineering etc. by its service object.Can be the hydraulic engineering of the plurality of target such as flood control, water supply, irrigation, generating service simultaneously, be called comprehensive utilization hydraulic engineering.Hydraulic engineering needs to build dam, dike, spillway, sluice, water inlet, channel, cross the dissimilar hydraulic structure such as mortise, log chute, fish pass, to realize its target.
In prior art; filter is indispensable a kind of device in hydraulic engineering; that a kind of filter screen that utilizes directly tackles impurity in water; remove water body recovery technology, particle; reduce turbidity; purify water, reduce the generations such as system dirt, bacterium algae, corrosion, with the equipment purified water and other equipment of protection system normally work.As China Patent No. " 201320332494.4 " discloses a kind of hydraulic engineering filter on November 13rd, 2013, its technical scheme is that described filter comprises housing and filter plate, it is characterized in that the both sides of described housing are respectively arranged with water inlet and delivery port, case top is provided with cover plate, housing bottom is provided with base plate, described filter plate is movably set in the middle part of housing cavity, filter plate is connected with cover plate by connecting rod, described water inlet is positioned at the downside of filter plate, delivery port is positioned at the upside of filter plate, is provided with soil cleaning port bottom the housing sidewall below delivery port.This patent reduces the dynamics that the rigid impurity such as stone in water clash into filter screen by changing the direction of a stream of water, although reduce the damage probability of filter screen to a certain extent.But in actual filtration process, the rigid impurity such as the stone in water, under the high speed of follow-up current drives, still can roll at a high speed in the housing, cause the dynamics of the rigid impurity such as stone when clashing into filter screen still comparatively large, and then cause filter screen easily to damage.
Utility model content
The purpose of this utility model is to solve the above-mentioned problems in the prior art, provides a kind of filter being applicable to hydraulic engineering, and the utility model can to reduce in water the rigid impurity such as stone to the shock number of times of filter screen and shock dynamics, avoids filter screen to damage.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of filter being applicable to hydraulic engineering, it is characterized in that: comprise " Y " shape pipe, outlet pipe, water inlet pipe and conical screen, described " Y " shape pipe comprises screen pipe, arm one and arm two, described screen pipe is vertically arranged, described arm one and arm two symmetry are connected to the lower end of screen pipe, and described outlet pipe is connected to the upper end of screen pipe, and described water inlet pipe is connected with arm one, described arm two is connected with blow-off pipe by control valve, and described conical screen is fixedly installed in screen pipe.
Described screen pipe top offers detachable installing hole.
The quantity of described conical screen is two, and two conical screen symmetries are fixed in screen pipe, and the conical top of two conical screens is respectively towards the two ends of screen pipe.
Be provided with the connection ring flat-plate be fixedly connected with screen pipe between two described conical screens, two conical screens are fixed on and connect on ring flat-plate.
Employing the utility model has the advantage of:
One, in the utility model, screen pipe is vertically arranged, arm one and arm two symmetry are connected to the structure of screen pipe lower end, the flow direction of the current entering " Y " shape pipe can be changed, and the flowing velocity of the rigid impurity such as stone in water can be reduced in largeizationr ground, and then be conducive to reducing the rigid impurity such as stone to the shock number of times of filter screen.And, in actual filtration process, when the rigid impurity such as the stone entering arm one are when the drive current downflow of follow-up current is to the junction of screen pipe, arm one, this three of arm two, can automatically flow under gravity in arm two, because arm two can avoid water impact, therefore can also prevent the rigid impurity such as stone from being driven by current and causing secondary impact.And filter screen adopts pyramidal structure, then can its inclined-plane along conical screen be made when the rigid impurity such as stone impinge upon on filter screen to slide, reduce the rigid impurity such as stone to the shock dynamics of filter screen.Compared with the prior art being representative with China Patent No. " 201320332494.4 ", the utility model can reduce conical screen and be subject to shock number of times from rigid impurity such as stones and shock dynamics, entering face can avoid filter screen to damage, and extends the service life of filter screen.In addition, arm two is connected with blow-off pipe by control valve, makes blowdown more simple and convenient.
Two, in the utility model, screen pipe top offers detachable installing hole, is convenient to the installation and removal of conical screen by detachable installing hole.
Three, in the utility model, adopt two symmetrically arranged conical screens can promote the filter effect of water, and even if one of them conical screen has damaged, another conical screen also can continue to keep filter effect.
Four, in the utility model, fixing two conical screens by connecting ring flat-plate, making the firm better effects if of two conical screens in screen pipe, also making the I&M of conical screen more simple and convenient simultaneously.
