Abstract
The utility model discloses a device for collecting planktonic alga, which comprises collecting nets, a filter mesh and a diversion valve, and is characterized in that the upper part of the device is provided with an upper collecting net, the lower part thereof is provided with a lower connecting net, and the bottom thereof is sleeved and connected with the diversion valve; and the device is conical, the filter mesh is arranged between the upper collecting net and the lower collecting net, and the bottom of the lower collecting net is sleeved and connected with the diversion valve. The filter mesh is made of a metal mesh. The device for collecting planktonic alga has the advantages of simple structure, convenient use and low cost, and can effectively collect planktonic alga in rivers and other turbid water.
Description
Technical field
The utility model belongs to the water environment protection technical field, more specifically relates to a kind of device of gathering planktonic algae, is applicable to that the planktonic algae of the more water body of muddy suspension is gathered.
Background technology
Traditional phytoplankton net is generally made with No. 25 bolting silks, and the phytoplankton that is widely used in water bodys such as lake, reservoir, river is gathered.In use, find in river and turbid water body that suspensions such as wave is assorted, silt are many, the guide valve of traditional phytoplankton net stops up easily, and impurity is more in the sample of collection, the observation in these disadvantages affect later stages.In the reality sampling, be badly in need of that the new equipment of gathering planktonic algae in these water bodys is arranged, to address the above problem.
Summary of the invention
The purpose of this utility model is to be to provide a kind of device of gathering planktonic algae, and is simple in structure, easy to use, with low cost, can effectively gather planktonic algae in muddy water bodys such as river.
To achieve the above object, the utility model is realized by following scheme:
A kind of device of gathering planktonic algae is made up of collecting net, screen pack, last collecting net, following collecting net, guide valve.The top of device is last collecting net, and the bottom is following collecting net, and there is guide valve its bottom.At the screen pack that different size is installed between the collecting net up and down.Its annexation is: this device is conical, and last collecting net links to each other with collecting net, following collecting net respectively, and screen pack is housed between last collecting net and following collecting net, and following collecting net links to each other with last collecting net, guide valve respectively.
As traditional plankton net relatively, screen pack effectively silt and the wave in the filtering water body is assorted, has solved the problem of obstruction guide valve, can improve the amount of algae of gathering in the muddy water body 50%.Simultaneously, the planktonic algae gatherer process is not made troubles yet, easy to carry.Simple in structure, easy to use, with low cost, can effectively in muddy water bodys such as river, gather planktonic algae.
Description of drawings
Fig. 1 is a kind of apparatus structure schematic diagram of gathering planktonic algae
Wherein: 1, collecting net; 2, screen pack; 3, go up collecting net; 4, following collecting net; 5 guide valves.
The specific embodiment
A kind of device of gathering planktonic algae is made up of collecting net 1 (being made up of last collecting net 3 and following collecting net 4), screen pack 2, guide valve 5 three parts.The top of device is last collecting net 3, and the bottom is following collecting net 4, its bottom noose guide valve 5.Its annexation is: this device is conical, between last collecting net 3 and following collecting net 4 screen pack 2 is housed, following collecting net 4 bottom noose guide valves 5.Screen pack 2 adopts wire netting to make, and current are after the filtration of last collecting net 3 and screen pack 2, and impurity and silt are blocked in top, and the water body that is rich in algae flows in following collecting net 4, collects through further filtering again.The liquid that contains algae through twice filtration is derived from guide valve 5.
Last collecting net 3: make with No. 13 (0.1 millimeter of mesh) bolting silks; No. 25 (mesh is 0.06 millimeter) bolting silks of following collecting net 4 usefulness are made, and market can be purchased.
2: two kinds of specifications of screen pack: 42 orders (0.35 millimeter of mesh); 35 orders ((0.42 millimeter of mesh)) metallic sieve is made, and market can be purchased.
Guide valve 5: copper, market can be purchased.
Claims (2)
1. device of gathering planktonic algae, form by collecting net (1), screen pack (2), guide valve (5), it is characterized in that: the top of device is collecting net (4) under last collecting net (3), bottom are, its bottom noose guide valve (5), it is conical that this device is, between last collecting net (3) and following collecting net (4), screen pack (2) is housed, following collecting net (4) bottom noose guide valve (5).
2. a kind of device of gathering planktonic algae according to claim 1 is characterized in that: described screen pack (2) adopts wire netting to make.
