Description

Technical Field

[0001] This utility model belongs to the field of magnetic stirrer technology, and in particular relates to a magnetic stirring device for oil testing. Background Technology

[0002] A magnetic stirrer is a laboratory instrument used for mixing liquids, primarily for stirring or simultaneously heating and stirring low-viscosity liquids or solid-liquid mixtures. Its basic principle is based on the repulsion and attraction of like poles in a magnetic field. The magnetic field drives a magnetic stir bar placed in a container to rotate in a circular motion, thereby achieving the purpose of stirring the liquid. Magnetic stirrers are widely used in oil testing.

[0003] Currently, a single-station magnetic stirrer for oil products can only hold one container. The container containing the oil sample to be tested must be removed after the oil sample has been stirred before another container can be placed on top. This makes the magnetic stirring operation of multiple oil samples uninterrupted and affects the efficiency of multi-sample stirring processing. Utility Model Content

[0013] As a further description of the above technical solution:

[0014] The single-station stirrer includes a housing, a rotary motor, and a magnetic turntable. The housing is installed inside the second connecting hole, the rotary motor is installed inside the housing, and the magnetic turntable is installed on the output end of the rotary motor.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a magnetic stirring device for oil testing, comprising:

[0031] The base 1 has a connecting column 2 on its top, and a tray 3 on the top of the connecting column 2. The top surface of the tray 3 has multiple placement slots 4.

[0032] Connector 5 is hinged to the connecting post 2, and the connector 5 is connected to the base 1 by a planar support ball bearing 6.

[0033] A single-station mixer 7 is mounted on the connector 5 and the single-station mixer 7 is attached to the bottom surface of the tray 3.

[0034] The connecting column 2 is a cylinder, and the multiple placement slots 4 are arranged in a circular array along the axis of the connecting column 2. By rotating the connecting piece 5, the single-station stirrer 7 can be moved to the bottom of different placement slots 4.

[0035] The connector 5 has a first connecting hole 8 and a second connecting hole 9. The first connecting hole 8 is sleeved on the connecting post 2, and the single-station stirrer 7 is installed in the second connecting hole 9, so that the connector 5 can rotate smoothly on the connecting post 2.

[0036] The single-station stirrer 7 includes a housing 71, a rotary motor 72, and a magnetic turntable 73. The housing 71 is installed in the second connecting hole 9, the rotary motor 72 is installed in the housing 71, and the magnetic turntable 73 is installed on the output end of the rotary motor 72. The rotation of the rotary motor 72 drives the magnetic turntable 73 to rotate, and the relative direction of the magnetic field on the magnetic turntable 73 changes, thereby driving the magnetic rotor in the container placed in the corresponding placement slot 4 to rotate at high speed, thereby realizing magnetic stirring.

[0037] The axis of the rotary motor 72 is parallel to the axis of the connecting column 2;

[0038] A control console 10 is mounted on the connector 5. The control console 10 is electrically connected to the rotary motor 72 and is used to control the rotational speed of the rotary motor 72.

[0039] Working principle: First, the containers of multiple prepared oil samples are placed in different placement slots 4, and a magnetic rotor is placed in each container. Second, under the support of the flat support ball bearing 6, the connecting piece 5 is pushed to rotate along the connecting column 2, moving the single-station stirrer 7 to the bottom of the corresponding container. Then, the single-station stirrer 7 works, causing the magnetic rotor in the corresponding container to rotate at high speed. That is, the rotation of the rotary motor 72 drives the magnetic turntable 73 to rotate, and the relative direction of the magnetic field on the magnetic turntable 73 changes, thereby driving the magnetic rotor in the container placed in the corresponding placement slot 4 to rotate at high speed, realizing magnetic stirring. During the process, the speed of the rotary motor 72 can be controlled by the control console 10. Finally, after stirring is completed, simply push the connecting piece 5 again and repeat the above operation to achieve continuous stirring of multiple containers and multiple oil samples.
