The invention discloses a chemical container inner side wall cleaning device. The device comprises a main body coiled plate, a rotating shaft connected with the main body coiled plate and a pluralityof bristles. The main body coiled plate is an elastic member, the main body coiled plate comprises a fixed end and a free end which are oppositely arranged in the coiling direction thereof, and the main body coiled plate comprises an outer end face and an inner end face which are oppositely arranged in the thickness direction thereof. The fixed end is connected with the rotating shaft, and the main body coiled plate is coiled around the axial direction of the rotating shaft. A plurality of extending cavities extending in the coiling direction of the main body coiled plate are formed in the inner end face. The outer end face is connected with the bristles. The outer end face is provided with a plurality of fluid outlets and inlets, and the fluid outlets and inlets are connected with a fluidextraction cavity. According to the device, the coiling degree of the main body coiled plate is controlled through the extending cavities, so that the device adapts to inner diameters of different containers and is high in universality; and the main body coiled plate is coiled and expanded to drive the bristles on the main body coiled plate to make contact with the inner side walls of the containers to achieve brushing and cleaning.

The invention discloses a method that is used to prepare superfine carbonyl nickel powder by the carbonyl nickel thermal decomposition. The method is that the carbonyl nickel and the carbon monoxide gas are mixed admission the decomposer to mix with the carbon monoxide main heat source gas whose preheating temperature is from two hundred and forty centigrade degree to three hundred twenty centigrade degree to make the carbonyl nickel decompose to from superfine carbonyl nickel powder whose granularity is from twenty nanometer to ten millimeter. The pressure of the decomposer is from 0.02MPa to 0.2MPa in the whole decomposition process. The invention avoids the complicated operation of separating the mixed gas after the decomposition, simplifies the preparation technology, reduces the cost of the production, and greatly reduces the produce of the wall built up.

The invention provides a hematology blood collection shaking device, which belongs to the technical field of medical equipment; it includes a support seat and a power shaking mechanism arranged inside the support seat, and the power shaking mechanism includes a power output unit, a post-processing unit, a collecting Assemblies and elastic boosters, the post-processing unit includes a conical spring frame and a counterweight, the inner side of the conical spring frame is provided with a counterweight near the end, and the top of the conical spring frame is fixedly connected with a swing A support plate, the outer side of the swing support plate is provided with a top fixing plate. The blood collection shaking device of the present application can continuously vibrate the top of the blood test tube loaded with blood, thereby reducing the phenomenon of blood hanging on the wall and adhesion during the shaking process, and effectively guaranteeing The accuracy of the blood volume can make the blood test tube be shaken quickly and efficiently, which has a protective effect on the blood test tube and ensures the continuity of the blood test tube during the shaking process.
