Abstract
The utility model provides an efficient location type magnetic stirrer which is used in scientific research, industrial experiment and industrial production. The efficient location type magnetic stirrer comprises a container and a magnetic stirring bar, and is characterized in that a main shaft is fixed at the center of the bottom inside the container, the magnetic stirring bar comprises a central seat which is provided with a shaft hole so as to be sheathed on the main shaft, and the outer wall of the central seat is provided with at least two magnetic bars in a radial direction. By adopting the efficient location type magnetic stirrer, the problems that the stirring bar of the existing magnetic stirrer can not rotate to stir in a locating manner, the stirring efficiency is low, the uniformity is bad, thermostability is bad, and the service life is short are solved; and the efficient location type magnetic stirrer is widely used in factories and laboratories, and used for cultivating producing biological vaccine, bacterium, cells and the like.
Description
The ㈠ technical field: the utility model relates to a kind of agitator that uses in scientific research, industrial experiment, the industrial production, especially a kind of efficient locate mode magnetic force agitator.
㈡ background technology: in industries such as pharmacy, bioengineering, need carry out the sealed, sterile operation usually and stir, designed magnetic stirring apparatus for this reason, it includes a container, puts into a kind of round bar shape magnetic stir bar that adopts poly-PTFE that strong magnetic stripe sealing is formed in container; Isolate the drive magnetic stir bar by outside magnet rotor during use and rotate, thereby reach the stirring purpose.Because in the existing structure, magnetic stir bar is freely to be placed in the container, be difficult for the location, stirring efficiency is low, and lack of homogeneity often needs with manual positioning, and manual positioning can not reach the requirement of sealed, sterile operation, is inconvenient to especially when being corrosive material for stirring operate.Existing on the other hand stirrer also exists easy to wear and produces powder pollution stirring material, and service life is short, defectives such as resistance to elevated temperatures difference.
The ㈢ summary of the invention: the purpose of this utility model will solve existing magnetic stirring apparatus exactly and be difficult for the location, and stirring efficiency is low, lack of homogeneity, and wear-resisting, resistance to elevated temperatures is poor, the problem that service life is short provides a kind of efficient locate mode magnetic force agitator.
Concrete scheme of the present utility model is: efficient locate mode magnetic force agitator, include a container and magnetic stir bar, it is characterized in that: be fixed with a main shaft in container inner bottom part center, described magnetic stir bar includes a centre mount, have shaft hole sleeve on the centre mount and be contained on the main shaft, at least two magnetic bars are arranged in centre mount outer wall radial arrangement.
For guaranteeing that magnetic stirring apparatus rotates flexibly, long service life, the centre mount of magnetic stir bar described in the utility model is designed to bearing block, and tight fit is equipped with outer shaft in inner hole of bearing seat, and tight fit is equipped with internal axle sleeve on main shaft, and inside and outside axle sleeve assembles movingly.
Clean for convenient, mention magnetic bar, the utility model is equipped with a handle in the connection of the upper end of magnetic stir bar centre mount.Save principle in line with practicality, magnetic stir bar centre mount outer wall radial arrangement described in the utility model has two magnetic bars, two magnetic bar coaxial arrangement.Certainly it also is feasible adopting three, though more feasible, effect is little, cost increases.
Magnetic bar described in the utility model is to be made of the stainless steel outer packed thin plate of magnetic stripe.Also can adopt other Wear-resistant, high-temperature resistant material to make exodermis.
Problems such as the utility model has successfully solved location, wear-resisting, high temperature resistant, and service life is short, the stirring efficiency height stirs, and is simple to operate, need not manual location, really accomplished the sealed, sterile operation.
The ㈣ description of drawings:
Fig. 1 is master of the present utility model (a cuing open) view.
Among the figure: 1-container, 2-stainless sheet steel, 3-magnetic stripe, 4-bearing block, 5-outer shaft, 6-internal axle sleeve, 7-handle, 8-fastening cap, 9-main shaft.
The ㈤ specific embodiment:
Referring to Fig. 1, the utility model includes a container 1(and can adopt stainless steel, glass, high temperature resistant, wear-resistant material by the time to make, be furnished with seal cover) and a magnetic stir bar, particularly: fix a main shaft 9 in container inner bottom part center, described magnetic stir bar includes a bearing block 4, tight fit is equipped with outer shaft 5 in bearing block 4 endoporus, and tight fit is equipped with internal axle sleeve 6(and adopts the fastening cap 8 fastening on main shaft 9), inside and outside axle sleeve 6 and 5 assembles movingly; At bearing block 4 outer walls two magnetic bars of coaxial arrangement (forming) radially by magnetic stripe 3 and stainless steel outer packed thin plate 2.Handle 7 is installed in bearing block 4 upper ends is at last promptly constituted preferred version of the present utility model.
The utility model also can save inside and outside axle sleeve 6 and 5 and handle, constitutes the simplest locate mode magnetic force agitator.
