Abstract
The invention discloses a back flush filter with a drainage board net. A communicating pipe is laid in a filter body, a water sucking hole is formed in any position of a pipeline, Venturi pipes are connected to the two sides of the communicating pipe, a drainage pipe is connected with the Venturi pipes, a grille is arranged at the end of the communicating pipe and provided with a plurality of drainage boards fixedly arranged on the grille, a ventilating pipe communicated with all the drainage boards is arranged at the tail ends of the drainage boards, a hose pipe connected with all the drainage boards is arranged at the head ends of the drainage boards, and the connection portions of the hose pipe and the drainage boards are sealed; folded edges are manufactured on the periphery of the top of an outer layer filtering net of the drainage board net, and a shakeproof net is installed on the upper portion of an inner layer filtering net. The back flush filter is manufactured by adopting the Venturi effect, when permeating through cracks and accumulating, water is fast sucked out of the sucking hole by the communicating pipe to prevent water leakage caused by water accumulation, the grille and the horizontal drainage board net are arranged on different layers to achieve stereoscopic drainage, the effect of filtering sewage is better, a double-layer structure is adopted in the filtering net, and the filtering net plays a role in filtering impurities to achieve the double insurance effect.
Description
Technical field
The invention belongs to filter plant technical field, be specifically related to the backwash filter of subsidiary draining expanded metals.
Background technology
Backwash filter, is that a kind of filter screen that utilizes is directly tackled the impurity in water, removes water body suspension, particle,Reduce turbidity, purify water, reduce the generations such as system dirt, bacterium algae, corrosion, with purify water and other equipment of protection system justThe precision equipment of normal work. Water enters self-cleaning filter body by water inlet, due to intelligent (PLC, PAC) design, systemCan automatically identify Impurity deposition degree, give blowoff valve signal automatic pollution discharge. Full-automatic back washing filter [1] overcomes traditional filteringThe pollutant holding capability of product is little, be subject to that dirt stops up, filtration fraction needs disassembly, cleaning and cannot monitor filter state etc. numerous shortcomings,There is the function of former water being filtered and automatically filter core being cleaned automatically blowdown, and system uninterruptedly supplies while cleaning blowdownWater, duty that can monitor filter, automaticity is very high. The various filtering accuracies to 3000um by 10um are coveredDemand, for client provides various water filtration device. Common screen pack mostly is single layer filter net in the market, people in useCan find, although using screen pack always, of long duration, in filter, still there will be the situation of obstruction.
Summary of the invention
For problems of the prior art, the object of the present invention is to provide the backwash filter of subsidiary draining expanded metalsDevice.
The technical scheme that the present invention takes is:
The backwash filter of subsidiary draining expanded metals, is characterized in that, comprises and filters body, grid and draining expanded metals, filters thisLay communicating pipe in body, be provided with suction hole at any place of pipeline, communicating pipe both sides be connected with Venturi tube, described drainpipe withVenturi tube connect, communicating pipe end be provided with grid, grid is provided with some drain bars that are installed on grid, drain bar endEnd establishes one and the permeability cell that is communicated with of each drain bar, establishes and connect the flexible pipe of each drain bar, flexible pipe and drain bar on drain bar head endJunction surface sealing; Described draining expanded metals is arranged on and filters body middle part, and draining expanded metals comprises outer filter net and internal layer screen pack,The surrounding at described outer filter net top is shaped with flanging, and the top of internal layer screen pack is provided with shockproof net, shockproof net and internal layer mistakeBetween filter screen for being rotatably connected.
Further, described outer filter net adopts stainless steel material to make.
Further, described draining expanded metals arranges along grid width, and evenly interval arranges.
Further, described communicating pipe be set to cross netted.
Beneficial effect of the present invention is:
Communicating pipe, both sides were connected with Venturi tube, and drainpipe is connected with Venturi tube, utilizes Venturi effect to make, when water is from splittingSeam infiltrates while gathering, and communicating pipe, water sucking-off rapidly from sucker, is avoided water to gather and leaks, and grid is provided with some lattice that are installed inDrain bar on grid, is located at different aspects by grizzly level drain bar screen cloth, realizes three-dimensional draining, to the filtration treatment effect of sewageFruit is better, and screen pack adopts double-decker, before use, the flanging by outer filter net surrounding by this device card at sewerExit, in the time there is situation about stopping up, only need can get internal layer screen pack by the handle on internal layer screen pack easilyGo out to clean, still play the effect of filtering foreign material at the process ectomesoderm screen pack cleaning, thereby form dual fail-safe.
Detailed description of the invention
The backwash filter of subsidiary draining expanded metals, is characterized in that, comprises and filters body, grid and draining expanded metals, mistakeFilter body in lay communicating pipe, be provided with suction hole at any place of pipeline, communicating pipe both sides be connected with Venturi tube, described drainingPipe be connected with Venturi tube, communicating pipe end be provided with grid, grid is provided with some drain bars that are installed on grid, drainingPlate end establishes one and the permeability cell that is communicated with of each drain bar, establishes and connect flexible pipe, flexible pipe and the draining of each drain bar on drain bar head endThe junction surface sealing of plate; Described draining expanded metals is arranged on and filters body middle part, and draining expanded metals comprises outer filter net and internal layer mistakeFilter screen, the surrounding at described outer filter net top is shaped with flanging, the top of internal layer screen pack is provided with shockproof net, shockproof net with inLayer screen pack between for being rotatably connected.
Further, described outer filter net adopts stainless steel material to make.
Further, described draining expanded metals arranges along grid width, and evenly interval arranges.
Further, described communicating pipe be set to cross netted.
Communicating pipe, both sides were connected with Venturi tube, and drainpipe is connected with Venturi tube, utilizes Venturi effect to make, and works as waterInfiltrate from crack while gathering, communicating pipe, water sucking-off rapidly from sucker, is avoided water to gather and leaks, and grid is provided with some setting firmlyDrain bar on grid, is located at different aspects by grizzly level drain bar screen cloth, realizes three-dimensional draining, to filtration place of sewageReason effect is better, and screen pack adopts double-decker, before use, the flanging by outer filter net surrounding by this device card at Xia ShuiThe exit in road, in the time there is situation about stopping up, only needs can easily internal layer be filtered by the handle on internal layer screen packNet takes out and cleans, and still plays the effect of filtering foreign material at the process ectomesoderm screen pack cleaning, thereby forms dual fail-safe.
The above is not limitation of the present invention, is noted that for those skilled in the artSay, not departing under the prerequisite of essential scope of the present invention, can also make some variations, remodeling, interpolation or replacement, these improvementAlso should be considered as protection scope of the present invention with retouching.
