Problems solved by technology

As for the anaerobic box, there are two main types on the market at present. One is the original imported anaerobic box made in Germany, the price is about 140,000 RMB. Regardless of whether the equipment is used or not, it requires a large amount of nitrogen to be fed without interruption, so routine maintenance The cost is high; the domestic product is the anaerobic box produced by Nanjing University, the price is about 60,000 yuan, and the equipment is required not to touch water
The above two anaerobic boxes not only have many shortcomings such as high price and high r

Embodiment 1

[0017] Embodiment 1: anaerobic box

[0018] Structure: It includes a box body and a bracket 7. A box body is set on the bracket 7. An operating seal 11 is arranged on the box body, and a fan 4 is arranged inside. The box body passes through the air inlet through the flow meter 2 and the high pressure The steel cylinders 1 are connected, and an exhaust port 5 is provided on the box wall, and the operation sealing seat 11 is equipped with a cover 9 . The cover 9 is a rectangular frame structure with an operation port in the middle, and a protrusion (protrusion: a welded circular sleeve located on one side of the operation port) on the operation port. The size of the inner opening of the operating seal 11 is consistent with the operating opening on the cover 9 , and a rubber sealing ring is arranged on the edge of the inner opening of the operating sealing seat 11 .

[0019] A drawer 10 may be arranged under the box body, and a direction wheel may be arranged at the bottom of th...

Embodiment 2

[0037] Example 2: Ultra-clean workbench

[0038] Structurally, the difference from Example 1 lies in that: an ultraviolet lamp 3 is added on the box body; and a black cloth is placed on the box body. A groove frame is arranged on the outer edge of the operating seal seat 11 of the box; the cover 7 adopts a glass plate structure, so that the push-pull type is inserted into the groove frame provided, and the round hole is closed when it is closed. The working process is as follows:

[0039] The first step is to replace the nitrogen cylinder used as an anaerobic box with a fresh air cylinder, and replace the iron plate welding cover with a push-pull glass plate cover; the second step is to connect the air cylinder, flow meter, etc. in sequence Components, turn on the pressure reducing valve and fan power switch, adjust the flow rate of the flowmeter to 3L / min, close the operation seal 11; the third step, after the original gas in the box is driven by fresh air, you can pull out ...

Embodiment 3

[0042] Example 3: Aquarium

[0043] Structurally, it differs from Embodiment 1 and Embodiment 2 in that: the bottom of the tank is provided with a drain port 6 to discharge the test water in the tank when it is used as an aquarium. The working process is as follows: the first step is to inject the test water body into the glass box through the operation seal 11, and then connect the high-pressure steel cylinder 1 (select the gas type according to the experimental needs) and the flow meter 2 and other components in turn; the second step is to open the pressure reducing valve And the fan power switch 8, adjust the flow meter 2 to reach the appropriate flow rate according to the needs of the experiment; the third step, after the original gas in the box is driven away by the carrier gas, various operations can be carried out.

[0044] Collect 100L of polluted water from heavily polluted rivers (4 barrels in 25L plastic barrels) and pour it into a glass box. Nitrogen is introduced ...

Abstract

The invention relates to a multifunctional experimental box, which comprises a box body and a bracing frame. The box body is arranged on the bracing frame; an operating seal retainer is arranged on the box body internally provided with a fan; the box body is connected with a high-pressure steel bottle through an admitting port by a flowmeter; an exhaust opening is arranged on a box body wall; the operating seal retainer is provided with a sealing cap; a uviol lamp is also arranged on the box body, and black cloth is arranged on an outer housing of the box body; and a waterspout is also arranged on the bottom of the box body. The multifunctional experimental box solves the disadvantages that an old anaerobic box cannot contact with water and the cost is high, can be used as an anaerobic box, also can be used as a superclean bench and an aquatic tank, and also can be used for collecting volatile compounds in a pollution system such as a water body, settlings or the like at the same time. The equipment composition of the multifunctional experimental box is simple, the operation is simple, the cost is low, and the functions of the single anaerobic box, the superclean bench and the aquatic tank are integrated.

Description

technical field [0001] The invention relates to equipment for biological experiment research, in particular to a multifunctional experiment box. Background technique [0002] The impact of reducing compounds distributed in polluted water, especially volatile reduced sulfides on the environment has been paid more and more attention. However, for a long time, due to the limitation of experimental equipment, the research on reduced compounds in water and sediment has been slow. The current detection methods for reducing substances mainly use anaerobic chambers or small sealed glass containers (erlenmeyer flasks or flasks, etc.). As for the anaerobic box, there are two main types on the market at present. One is the original imported anaerobic box made in Germany, the price is about 140,000 RMB. Regardless of whether the equipment is used or not, it requires a large amount of nitrogen to be fed without interruption, so routine maintenance The cost is high; the domestic product...
