Abstract

The utility model discloses an experimental stirrer, which relates to the technical field of stirring, and comprises a fixed disc which is quickly fixed on a tabletop through a sucker, then liquid to be stirred is placed into a cup body, then the action of pulling a handle is repeated, so that the liquid in the cup body is repeatedly switched and stirred by a plurality of stirring blades in clockwise rotation and anticlockwise rotation, the stirring and mixing efficiency of the liquid is improved, after the stirring is finished, the sucker is released from being adsorbed on the tabletop through pulling a first limit, and the first limit handle is arranged at a position far away from the sucker to be pulled, so that fingers can prop against the cup body when the sucker is pulled, the cup body is prevented from being toppled over due to the fact that one side of the sucker is pulled up or the sucker is pulled open for adsorption, and meanwhile, the cup body is prevented from being toppled over due to the fact that the force of pulling a second handle is excessive when the liquid is stirred, and the sucker is arranged through the second handle.

Description

Experimental stirrer Technical Field The utility model relates to the technical field of stirring, in particular to an experimental stirrer. Background The experimental stirring technology belongs to the crossing field of laboratory instruments and chemical technology, and mainly relates to homogenization, dispersion, dissolution and reaction process reinforcement of liquid, slurry or gas-liquid mixture. Through retrieving the laboratory agitator of publication number CN206810157U, including a motor, the output shaft of motor has stainless steel stirring rod through shaft coupling coaxial coupling, and stainless steel stirring rod's lower extreme coaxial coupling has the disc, and the periphery of disc is provided with 6~10 group's blades along circumference interval evenly, and arbitrary a set of blade is all including an upper blade and a lower blade respectively, and upper blade and lower blade all are the rectangle, and upper blade sets up the upside at the disc, and lower blade sets up the downside at the disc. The coupler comprises an upper cover and a lower cover, the upper cover is fixedly connected with the output shaft, the lower cover is fixedly connected with the stainless steel stirring rod, and the upper cover is connected with the lower cover through bolts. The utility model uses the shaft coupling to connect the stirring rod, can change the stainless steel stirring rod with various lengths and can also change the discs with various diameters, so that the stirrer can be suitable for containers with various depths and inner diameters. The blade is the rectangle, sets up the upside at disc periphery, simple structure, and it is effectual to mix, can effectively prevent the sediment of material. However, the current small-sized stirring device often needs to be used for stirring by hands of an experimenter, but when stirring, the stirring force is unstable, and the stirring force causes liquid to flow out, so that waste is caused and potential safety hazards exist.
