Description
Technical field
The utility model relates to a kind of tank, relates in particular to a kind of for studying the novel water tank of Pollutants Diffusion test.
background technology
Experimental tank is all widely used in research fields such as hydraulics, water environment, environmental pollutions, be mainly used in specifically studying water flow structure, water stream characteristics, vegetation resistance, the flow rate of water flow distribution characteristics of the water bodys such as river, open channel, and study the aspects such as bottom mud in lake pollutant release.Follow at present the increasingly serious of environmental disruption situation, the cry of protection of the environment is also more and more higher.Under this prerequisite, require that researchist must go deep into the environmental behaviour of this area pollutant, careful research.
For mine environment research worker, how studying mining behavior is an important process on the impact of environment.Mining activity not only easily makes surface collapse, but also can produce a large amount of gangues; So gangue backfill or underground filling become general selection.For under the wetland of mining area or the surface subsidence great majority that under poor-water region, coal mining causes be to adopt solids (as gangue, building waste etc.) backfill sinker area method to administer; Yet the environmental safety to the method, and the environmental behaviour of gangue pollutant under water environment is still lacked and fully studies and do not have more scientific rational test water groove carry out simulation test and fully study at present.
utility model content
For the weak point in addressing the above problem, it is a kind of for studying the novel water tank of Pollutants Diffusion test that the utility model provides, simulation heterogeneity water body, flow characteristics, the Diffusion Law of research solid pollutant (as gangue, building waste etc. discharge pollutant).
For solving above technical matters, the technical solution adopted in the utility model is: a kind of novel water tank of testing for studying Pollutants Diffusion, comprise water inlet system, tank body, and water inlet system is comprised of water inlet pipe, isocon, tongs and constant-current stabilizer;
Tank body is divided into four bypass channels by three water-stop sheets that highly fall progressively by tank body interior, and the difference in height between every two adjacent water-stop sheets is 7.5cm.
In tank body at grade along being respectively arranged with axis water sample sampling point and limit wall water sample sampling point on middle of the stream line and cell wall;
Axis water sample sampling point and limit wall water sample sampling point respectively arrange 15 on conplane vertical direction, interval 5cm between every two axis water sample sampling points or limit wall water sample sampling point.
On water inlet pipe, be provided with for the tongs to water inlet is shunted or interflow acts on.
The utility model is simple in structure, easy to use, easy to operate, be convenient to observe, as required can be respectively or simulate Static and dynamic water environment simultaneously, and water sampling is simple.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model one-piece construction schematic diagram.
Fig. 2 is vertical view of the present utility model.

embodiment
As Figure 1-Figure 4, the utility model comprises water inlet system, tank body and outlet system.Water inlet system is comprised of water inlet pipe 1, isocon 3, tongs 2 and constant-current stabilizer 4; Tank body is highly passed by three
In tank body at grade along being respectively arranged with axis water sample sampling point 6 and limit wall water sample sampling point 7 on middle of the stream line and cell wall;
Axis water sample sampling point 6 and limit wall water sample sampling point 7 respectively arrange 15 on conplane vertical direction, interval 5cm between every two axis water sample sampling points 6 or limit wall water sample sampling point 7.
On water inlet pipe 1, be provided with for the tongs 2 to water inlet is shunted or interflow acts on.
Process of the test:
As shown in Figure 2, when flow through water pump, flowmeter of test water enters after tank body by water inlet pipe 1, by isocon 3, current are sent in four bypass channels.According to test needs, when needs are simulated low flow velocity high viscosity current (as Flow in Wetland) flow state, each isocon end need connect constant-current stabilizer 4; Otherwise can not connect water stabilizing device.For absolutely proving the embodiment of test unit, being Flow in Wetland herein and is below that example describes.
As Fig. 4.The flow state more complicated of current in actual Wetland Environment, no matter be the Diffusion Law of spoil pollutant under simulation static state or current intelligence, all need to do several groups of tests and contrast and average, therefore in tank body of the present utility model, design four bypass channels and be necessary.Between each bypass channel, with acrylic, do water-stop sheet 8, select acrylic to be because this quality of materials is light, and need dismounting also convenient according to experiment.Water-stop sheet height is not identical, between every two water-stop sheets, highly differs 7.5cm.
As shown in Figure 2 and Figure 3, the utility model from second isocon, arranges tongs before each isocon along water inlet direction, for regulating the water yield of controlling in bypass channel.So design is because Flow in Wetland disturbance is influential to Pollutants Diffusion, the simulation of this kind of situation is realized by adjusting tongs, when water inlet, close tongs, current flow in first bypass channel, then through first water-stop sheet overflow, enter second bypass channel, same method current overflow in two bypass channels below; When entering each bypass channel, current can produce disturbing phenomenon because of the difference in height between water-stop sheet.
The research of Pollutant Dispersion Law be unable to do without the sampled point water sampling test arranging.During for fear of each sampling, sampling location changes test findings is exerted an influence, and in the utility model tank body, along center line and cell wall, has designed respectively axis water sample sampling point 6 and limit wall water sample sampling point 7, as shown in Figure 1, Figure 3 and Figure 4 shown in.Along middle of the stream line and cell wall, respectively establish 1 sampled point at grade, totally 15 sampled points on vertical direction, interval 5cm between every two identical sampled points, two kinds of sampled points of below are 6.5cm apart from bottom land; Two kinds of sampled points are connected to flume wall by sampling pipe and sample outward.
In sum, compare with experimental tank in the past, the utlity model has following advantage:
Not only can simulate the open-channel flows such as river, and can Simulated Wetland current; Can need to design respectively static current, dynamic current, flow-disturbing according to test, or static, the dynamic current of design simultaneously, for pollutant provides more convenient, simple and direct test unit in the Diffusion Law research of water environment; Fixed sample point is set, had both facilitated laboratory staff sampling, avoided again the interference of human factor in sampling process.
Above-mentioned embodiment is not to restriction of the present utility model; the utility model is also not limited in above-mentioned giving an example; the variation that those skilled in the art make within the scope of the technical solution of the utility model, remodeling, interpolation or replacement, also all belong to protection domain of the present utility model.
