Description

Technical Field

[0001] The invention relates to the technical field of stirring, and more particularly to a stirring device for chemical detection. Background Art

[0002] Chemical reagents are relative standard substances for chemical research and component analysis. They are an important condition for scientific and technological progress and are widely used in the synthesis, separation, qualitative and quantitative analysis of substances. Chemical reagents are indispensable in the daily work of factories, schools, hospitals and research institutes. In the process of testing chemical reagents, they need to be mixed through mixing devices.

[0003] However, in the prior art, the stirring operation of chemical reagents is relatively inconvenient, and the stirring effect of chemical reagents is poor, and the mixing uniformity of chemical reagents cannot be guaranteed; the uneven stirring of samples will have a great impact on the test results. At the same time, the existing stirring devices mostly adopt a tank structure, and due to the numerous internal parts, it is difficult to clean thoroughly after use, so that a certain stirring device is only suitable for stirring the same type of chemical reagents, which greatly limits its use.

[0004] Therefore, developing a stirring device for chemical detection that has good stirring uniformity and is easy to clean is an urgent problem that needs to be solved by those skilled in the art. Summary of the invention

[0005] In view of this, the present invention provides a stirring device for chemical detection which has good stirring uniformity and is easy to clean.

[0014] Preferably, a slider is provided on the top of the rotating plate, a first slide rail is provided on the top of the tank body at a position corresponding to the slider, and the slider is slidably connected to the first slide rail. The slider slides in the first slide rail, which not only facilitates the rotation of the rotating plate, but also provides support for the rotating plate.

[0015] Preferably, a bracket is provided at the bottom end of the tank body, and a guide rod is connected to the bracket, and the guide rod passes through the spiral blade. The guide rod guides the spiral blade and the moving block, thereby achieving the purpose of the screw rotating the moving block to move up and down.

[0016] Preferably, a plurality of the wall brushes are connected by a wall brush holder, and the wall brush holder is provided with a plurality of groups along the inner wall of the tank body, and the wall brush holder comprises: a fixed tube and a sliding rod; the wall brush is fixed between two fixed tubes, and the sliding rod is connected to the fixed tube; a second annular slide rail is provided at a position corresponding to the sliding rod on the inner wall of the tank body, and the sliding rod is slidably connected to the second slide rail. The sliding rod slides in the second slide rail and can rotate along the inner wall of the tank body to clean the inner wall of the tank body.

[0017] Preferably, a telescopic cylinder is provided at the end surface of the rotating plate, and a claw is provided at the telescopic end of the telescopic cylinder, and the claw is engaged with the fixed tube. When the telescopic cylinder is connected to the fixed tube, the wall brush can be driven to rotate along the inner wall of the tank body, and the sliding rod can be driven to slide in the second slide rail.

[0018] Preferably, a valve is provided at the liquid outlet, which facilitates taking out the mixed liquid for testing.

[0019] Preferably, the surfaces of the spiral blade and the stirring blade are provided with through holes, which allow liquid to pass through and increase the degree of stirring of the liquid.
