The utility model discloses a special device for filtering and concentrating blue-green algae. The device comprises a filtering net and a bracket, wherein the filtering net is arranged on a net frame; the net frame is obliquely arranged on the bracket; a spraying pipe connected with an algae conveying pipe is arranged on the high-end transverse side of the filtering net; an algae collecting channel is formed in the low-end transverse side of the filtering net; a water return pipe connected with a filtrate collecting pool is arranged below the filtering net; the filtering net has a double-layer structure; the upper layer is a fine filtering net, and the lower layer is a coarse filtering net; the inclination angle of the bracket is adjustable; the bottom of the bracket is fixed on the cement ground through an expansion screw; the algae slurry filtered by the fine filtering net automatically flows to the algae collecting channel at the front end of the device, and the filtered liquid is discharged to the filtrate collecting pool through a pipeline arranged on the cement ground. The algae-water mixture is filtered by the special device, the volume of the algae-water mixture is greatly reduced, the water content of the concentrated algae slurry is low, the device is simple in structure, low in price and good in filtering and concentrating effect, power is not required, the energy is saved, and secondary pollution is avoided. The device is widely applied to filtering and concentrating of cyanobacterial bloom in lakes, rivers and the like, and the subsequent treatment of the algae slurry is convenient.

Description

A kind of filtering and concentrating blue-green algae special purpose device
Technical field
The utility model relates to a kind of filtering and concentrating blue-green algae special purpose device, the device of the filtering and concentrating of the bloom blue algae broken out in especially applicable lake and river course.
Background technology
Current domestic many waters, lake for example, the trend that eutrophication occurred, a large amount of blue-green algaes has appearred on the water surface, and assemble the impact that thickness is subject to the factors such as sunlight, temperature, wind-force and wind direction, freshwater resources to have been caused to severe contamination, in order addressing this problem, just must to have been salvaged the blue-green algae on lake surface in time.Although machinery is salvaged, efficiency is very high, and the blue-green algae moisture content extracted is very high, brings a lot of inconvenience to the subsequent treatment of blue-green algae, needs further filtering and concentrating, thereby facilitates for the blue-green algae post processing after collecting.
The utility model content
The purpose of this utility model is to propose a kind of filtering and concentrating blue-green algae special purpose device, the algae aqueous mixtures concentration that can transport according to the defeated algae pipe of installing on it selects to adjust the filter screen in filter screen angle of inclination and suitable aperture, improved blue-green algae filtering and concentrating effect, device spray line structure is difficult for being stopped up by impurity, treating capacity is large, and backwashing period is long.
The utility model is the technical scheme that realizes that its purpose is taked: a kind of filtering and concentrating blue-green algae special purpose device, comprise filter screen and support, described filter screen is placed on screen frame, screen frame is inclined on described support, the spray line be connected with defeated algae pipe along the high-end horizontal edge setting of described filter screen, low side horizontal edge along described filter screen is established Ji Zaoqu, and the return pipe be connected with the filtrate collecting pit is established in described filter screen below.
Described filter screen is double-decker, and upper strata is fie screen, and lower floor is coarse strainer, and the angle of inclination of described support is adjustable, and frame bottom is fixed with setscrew and cement flooring.
Described spray line is closed coating steel pipe, and the spray line valve is equipped with at its two ends, is evenly arranged the circular mouth that sprays on spray line, sprays the opening direction of mouth and the angle that the filter screen inclined-plane is 35-45o.
Described defeated algae pipe is coating steel pipe, and on itself and cement flooring, the pipe of vertical direction is equipped with defeated algae tube valve, and the pipe lower end parallel with cement flooring supported fixing with angle iron frame; Described support and screen frame adopt stainless steel material to make.
The beneficial effects of the utility model are as follows:
1, screen pack is two-layer, than the filter screen of fine pore, is arranged in upper strata, and than the filter screen in gross porosity footpath, in lower floor, the filter screen material is anticorrosive, long service life.Two layers of mesh is placed on the stainless steel screen frame simultaneously, has both guaranteed filter effect, has strengthened again robustness and the life cycle of filter screen.
2, the riding angle is adjustable, makes the screen pack angle of installation on it also adjustable, can adjust at any time as required angle and adapt to the algae aqueous mixtures that filters variable concentrations.The rack supporting structure bottom is fixed with setscrew and cement flooring, guarantees whole filter more stable and stronger.
3, valve is equipped with at the spray line two ends, can regularly open and remove the inside impurity, guarantees to spray mouth and is not stopped up by impurity.Spray and mouthful to have best aperture and spacing, and its opening direction and filter screen inclined-plane are at an angle, the algae aqueous mixtures that can evenly, fast, efficiently distribute carries out filtering and concentrating to filter screen.
4, the input that the valve on defeated algae pipe can be regulated the algae aqueous mixtures as required, make the thickening filtration effect continual and steady.
The accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is right TV structure schematic diagram of the present utility model;
The local structure for amplifying schematic diagram that Fig. 3 is A in Fig. 1.
In figure: 1, support, 2, defeated algae pipe, 3, spray line, 4, coarse strainer, 5, fie screen, 6, return pipe, 7, screen frame, 8, Ji Zaoqu, 9, the spray line valve, 10, defeated algae tube valve, 11, spray mouthful.
The specific embodiment
Referring to accompanying drawing 1-3, the utility model comprises filter screen and support 1, and filter screen is double-decker, upper strata is fie screen 5, and lower floor is coarse strainer 4, and two-layer filter screen is installed in screen frame 7, screen frame 7 is inclined on support 1, and the angle of inclination of support is adjustable, and frame bottom is fixed with setscrew and cement flooring.The spray line 3 be connected with defeated algae pipe 2 along the high-end horizontal edge setting of described filter screen, spray line 3 adopts closed coating steel pipe, and spray line valve 9 is equipped with at its two ends.The spray line valve can adopt zinc-plated steel Thread valve door.Be evenly arranged the circular mouth that sprays on spray line, spray the opening direction of mouth and the angle that the filter screen inclined-plane is 40o.Defeated algae pipe 2 adopts coating steel pipes, its with cement flooring on the pipe of vertical direction defeated algae tube valve 10 is housed, defeated algae tube valve adopts the screw thread valve of zinc-plated steel, the defeated algae pipe pipe lower end parallel with cement flooring fixed with the angle iron frame support.Establish collection algae canal 8 along the low side horizontal edge of filter screen.The return pipe 6 be connected with the filtrate collecting pit is established in the filter screen below.
