Description
Technical Field
The invention relates to the technical field of manufacturing of safety and environment-friendly equipment, in particular to a multifunctional operation box for safety operation of mercury-containing devices and environment-friendly recycling of mercury liquid.
Background
Since mercury-containing devices are still widely used in the fields of chemical industry, metallurgical casting, medical treatment, etc., and mercury forms very fine small particles after being inadvertently sprayed onto the ground, and adheres to walls, clothes, and the ground, if not treated, it is always present for several years or even decades in the future. The current common method for treating the scattered mercury is to scatter a layer of sulfur powder on the removed mercury to form mercury sulfide so as to reduce the volatilization of the mercury sulfide. However, the method has the great disadvantages that mercury is not easy to recycle, the treatment is not clean and thorough, and part of mercury still volatilizes into the air. Mercury can enter the body through skin, respiratory organs or digestive systems to harm human health, and can poison people through high-concentration mercury vapor in air, and is a main mode for causing human mercury poisoning. Even if a ventilation device with good performance is installed, the discharge of mercury vapor to the outside can still pollute the external air, and the concept of environmental protection of a illegal laboratory is provided. In order to standardize the safe use of mercury, national occupational safety and health, environmental protection agencies have established regulations and standards applicable to the health and safety of practitioners exposed to mercury.
At present, a set of safe and reliable method and device are not suitable for safe operation of mercury in a laboratory. The international known mercury porosimeter manufacturer does not have a matched mercury liquid operation and recovery device. Therefore, developing a set of device which can safely and conveniently disassemble and wash the mercury porosimeter to thoroughly avoid volatilization and scattering of mercury liquid and effectively recycle the mercury liquid is a very meaningful work.

Detailed Description
The invention is described in further detail below with reference to the accompanying drawings.
As shown in fig. 1:1, disassembling, cleaning and deep cleaning of mercury-containing devices are realized through three working areas; 2, realizing the recovery of mercury through a conical area at the bottom of the treatment tank; 3, by adopting an immersed water sealing operation mode, the volatilization of mercury directly exposed to air is completely avoided; 4, enhancing the adsorption of mercury by arranging a mercury adsorption resin box on the water outlet and the oil outlet; 5, by arranging 15-degree water outlets and current stabilizing plates in the three communicated treatment tanks, the full precipitation of mercury liquid in the current treatment tank is ensured; and 4, the treatment tank uses transparent organic glass as a main body material, so that the operator can observe the treatment tank conveniently.
The working principle of the invention is as follows:
The operator first fixes the dilatometer on the support arm 4 in the processing groove of the disassembly area, uses the tool to unscrew the sealing ring and the metal cover, and can avoid the sample tube from being broken due to slipping. After the metal cover of the dilatometer is opened, the pressure is reduced, and most of the mercury liquid in the tube flows into the mercury discharge beaker 8 arranged right below the mercury discharge beaker, and the mercury liquid can be directly recycled. Not all of the pressed mercury is expelled during the depressurization, however, a small amount of mercury remains or is trapped in the sample, which, together with the experimental sample, is poured into the mercury-containing sample beaker 9 for further cleaning and recovery. The disassembled dilatometer is moved to a treatment tank of a hot water cleaning area, the treatment tank of the area is filled with an aqueous solution mixed with a detergent, and a hot water shower head 17 is arranged above the cleaning tank and is used for cleaning greasy dirt and residual mercury of all parts of the dilatometer after being emptied. And then transferring the dilatometer to a deep cleaning area, wherein a purified water shower head 18 is arranged above the treatment tank of the area, and the dilatometer can be directly taken out for drying treatment after being further cleaned for later use. During the cleaning process, mercury liquid which is inadvertently sprayed into each water tank can be deposited to the bottom of the water tank, and when a certain amount of mercury liquid is accumulated, the control valve 20 at the bottom of the water tank can be opened to recover mercury liquid. The collection container of mercury liquid and greasy dirt is placed on a lifting platform to ensure safe taking and placing.
