There is agitating device, so that there is the problems such as temperature distribution is non-uniform and cooling hysteresis quality is big by temperature reducing substance.Once testing
When vessel breaks situation, the liquid of spillage can corrode or damage experimental provision, and the liquid of spillage is easy to cause equipment short-circuit, or
Corrode instrument and laboratory bench, can also be caused harm to the human body when serious.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of, and the circularly cooling with magnetic agitation pumps,
Good cooling effect, strong operability, safety coefficient are high.
Purpose of the utility model is realized as follows:
A kind of circularly cooling pump with magnetic agitation, including refrigerating plant packet described in refrigerating plant and magnetic stirring apparatus
Outer cylinder and inner cylinder are included, barrel one week of the outer cylinder is equipped with elastic slice, and the elastic slice is contacted with the bucket wall of inner cylinder, the cylinder of the inner cylinder
It is interior to be equipped with magnetic stir bar, the first insulated sponge layer, the magnetic stirring apparatus are equipped between the cylinder bottom of the inner barrel and outer barrel
Including motor and magnetic disk, the motor is located at the bottom of pump case, and the magnetic disk is close to outer cylinder.
Preferably, the elastic slice is connected by the barrel of spring and outer cylinder.
Preferably, the spring is detachable, and both ends are equipped with screw, and the elastic slice and outer cylinder correspond to screw and be equipped with spiral shell
Hole.
Preferably, the elastic slice is arc, and curved opening is towards outer cylinder barrel.
Preferably, the magnetic disk is coated with the second insulated sponge layer.
Preferably, third insulated sponge layer is also enclosed with outside the barrel of the inner cylinder.
Preferably, control panel is equipped with above the pump case, the control panel is equipped with refrigeration switch and magnetic agitation
Knob.
The beneficial effects of the utility model are:
The utility model uses magnetic agitation, makes to be eliminated cooling hysteresis quality by the uniformity of temperature profile of temperature reducing substance, shortened
Temperature fall time tests material and pollutes experimental facilities, while preventing corrosion experiment equipment and experiment work when can prevent inner cylinder from rupturing
Make platform, avoid damaging laboratory technician, safety coefficient is high.Even if inner cylinder ruptures, it is only necessary to replace inner cylinder, clean outer cylinder
Re-start experiment.Magnetic stirring apparatus is protected using insulation foams simultaneously, agitating device is effectively prevent to freeze, is extended
The service life of agitating device.

Specific embodiment
Referring to Fig. 1, the utility model relates to a kind of, and the circularly cooling with magnetic agitation is pumped, including refrigerating plant and magnetic force
Agitating device, the refrigerating plant include outer cylinder 1 and inner cylinder 2, and barrel one week of the outer cylinder 1 is equipped with elastic slice 3, the elastic slice 3
It is contacted with the bucket wall of inner cylinder 2, magnetic stir bar 4 is equipped in the cylinder of the inner cylinder 2, is set between the inner cylinder 2 and the cylinder bottom of outer cylinder 1
There is the first insulated sponge layer 5, the magnetic stirring apparatus includes motor 6 and magnetic disk 7, and the motor 6 is located at the bottom of pump case 8
Portion, the magnetic disk 7 are close to outer cylinder 1.
The elastic slice 3 is connect by spring 9 with the barrel of outer cylinder 1.3 upper layer and lower layer of elastic slice are evenly arranged on the barrel of outer cylinder 1, close
Manage fixed inner cylinder 1.
The spring 9 be it is detachable, both ends are equipped with screw, and the elastic slice 3 and the corresponding screw of outer cylinder 1 are equipped with screw hole.
The rebound of elastic slice 3 effect is good, when 9 elasticity of spring becomes smaller, only needs to change spring, reduces material cost.
The elastic slice 3 is arc, and curved opening is towards 1 barrel of outer cylinder.
The magnetic disk 7 is coated with the second insulated sponge layer, and the second insulated sponge layer protection agitating device freezes
Knot.
Third insulated sponge layer, the third insulated sponge layer and the first insulation are also enclosed with outside the barrel of the inner cylinder 2
