Description
Technical field
The present invention relates to the blue-green algae cleaning plant, is a kind of blue algae catching device and method.
Background technology
Blue-green algae be the simplest, the most original, do not have a nuclear protokaryon unicellular organism, there is the colloid clothing cell membrane outside of most of blue-green algaes.Situations such as loss of chemical fertilizer, sanitary sewage, livestock and poultry cultivation, industrial pollution, burning mineral fuel cause the excessive nutrient of water body, and blue-green algae is breeding in a large number in water body.Outburst " green tide " and " red tide " phenomenon caused water quality deterioration when blue-green algae bred on a large scale, exhausted water oxygen gas in the time of seriously and caused the death of fish.Its manner of cleaning up mainly is divided into chemistry and biological two kinds, as by the activated carbon water purifier contaminated water source being purified, and cultures fingerling predation blue-green algae such as silver carp.
Except that above-mentioned method, also has mode by labor cleaning blue-green algaes such as machinery equipments.As the patent No. ZL200710071907.2 of Chinese patent literature publication, April 23 2008 notice of authorization day, utility model title " multifunctional water surface algae removing machine "; The application number 200810195881.1 of Chinese patent literature publication, open day on February 18th, 2009, denomination of invention " a kind of method of removing blue-green algae in the pond ", the device of above-mentioned blue-green algae cleaning is comparatively complicated, cost is higher, and the method for blue-green algae cleaning is only applicable to the pond, and cleaning, range of application are less.
Summary of the invention
For overcoming above-mentioned deficiency, a kind of blue algae catching device and the method that provide to this area is provided, make it can solve the technical problem of blue-green algae cleaning in the water body.The objective of the invention is to be achieved through the following technical solutions.
A kind of blue algae catching device, this catching device comprise fishes for body and fishes for lid, fishes for body and comprises screen frame frame, float, tracheae, fishes for net, fishes for lid and is made up of cover framework, separation net.Its design main points are that the described net of fishing for of fishing for body is a bag shape, fish for net one end and are connected with the screen frame frame, and the other end is provided with slide fastener, and this end is provided with tracheae, and tracheae is provided with float; Described cover framework of fishing for lid is provided with separation net; The screen frame frame of fishing for body fastens with the cover framework of fishing for lid.The cover framework of fishing for the screen frame frame of body and fishing for lid places water body, and the frame segment mouth surfaces, and spurs this catching device by external force, and blue-green algae enters the net of fishing in the screen frame frame from the separation net of cover framework, and blue-green algae is gathered in fishes for sieve bottom.
Described fish for body fish for net by the screen frame frame to the tapered contraction of slide fastener.Blue-green algae is flowed to enter from the separation net of cover framework with water body and fishes for net, and taper is shunk fishes for net and blue-green algae is come together in fish for sieve bottom.
Described fish for body and fish for lid be arranged as two groups, screen frame frame, float, tracheae, fish for net, cover framework, separation net are corresponding is provided with.According to the length of boats and ships or descaling machine, independent assortment is fished for body and is fished for lid for two groups, to have improved cleaning efficiency and cleaning area.
The design main points of blue algae catching method are that the hole count on the described unit area of fishing for net and the separation net of fishing for lid of fishing for body is different, the screen frame frame of fishing for body fastens with the cover framework of fishing for lid, fish for body, fish for to cover and slide by the external force pulling at the water surface, blue-green algae enters from separation net and fishes for net, comes together in and fishes for sieve bottom.By physics mode, reach the purpose of cleaning water body blue-green algae, have environmental protection, quick, easy-operating characteristics.
Described hole count of fishing for net is controlled between 200～400 orders, and the hole count of separation net is controlled between 30～100 orders.The hole count on net, the separation net unit area is fished in " order " expression, and this number range guarantees that effectively blue-green algae enters this catching device from separation net, and can not flow out from fish for net, the resistance to water-flow when having reduced work simultaneously.
The present invention design is comparatively reasonable, simple in structure, easy to use, is applicable to river course, seawater environmental protection, and the cleaning of blue-green algae in the plant.
Description of drawings
Fig. 1 is the body structure schematic diagram of fishing for of the present invention.
Fig. 2 is that of the present invention fishing for covered structural representation.
Fig. 3 is that Fig. 1 and Fig. 2 make up schematic diagram.
Above figure number and title: 1, screen frame frame, 2, slide fastener, 3, float, 4, tracheae, 5, fish for net, 6, the cover framework, 7, separation net.
The specific embodiment
Now in conjunction with the accompanying drawings the present invention is further described as follows.Screen frame frame 1, cover framework 6 are welded by stainless steel, and the length of screen frame frame, cover framework is 1m, and wide is 0.5m.What screen frame set up the marsupial shape fishes for net 5, fishes for that net is long to be 4.5m, and the hole count of fishing for net is made as between 200～400 orders.The cover framework is provided with separation net 7, and the hole count of separation net is made as 50 orders.Slide fastener 2 closing ins are crossed by the Netcom that fishes for of screen frame frame, the bottom and the height between the slide fastener of fishing for net are 0.1m, the slide fastener annex is provided with float 3, and the tracheae 4 that float is made by rubber tube is connected with the net of fishing for of screen frame frame, and the screen frame frame of fishing for body fastens with the cover framework of fishing for lid.
Fishing for body and fishing for to cover of this catching device is arranged as two groups, is positioned over the rear portion of boats and ships or descaling machine, fishes for the screen frame frame and the water body that places of fishing for lid of body, makes the cover framework keep vertical as far as possible, and the screen frame frame surfaces with the frame notch portion of covering framework.Start boats and ships or descaling machine, the blue-green algae that floats on the water surface enters the net of fishing in the screen frame frame from the separation net of cover framework, and blue-green algae is gathered in fishes for sieve bottom.During cleaning, only need this catching device is taken out from water, unzip, can will fish for the interior blue-green algae of net and pour out.Open the cover framework of fishing for lid, can to fish for net, separation net is cleared up and change.
