Problems solved by technology

However, the device is relatively large in size (with a drive motor), and the price is relatively high, so it is not easy to popularize, and most of them use top drive, which is not easy to match with common reaction vessels, and has poor versatility

Embodiment Construction

[0039] The intelligent heating agitator and its control method of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0040] Such as figure 1 As shown, the intelligent heating stirrer of the present invention comprises a permanent magnetic stirrer, a driving and heating device, an intelligent controller, and a temperature sensor; 4 permanent magnets of the permanent magnetic stirrer are opposite to the electromagnets of the driving device, and when the driving device When the magnetic field generated by the electromagnet rotates, the permanent magnetic stirrer will rotate accordingly; the electromagnet is composed of two U-shaped iron cores inlaid together and wound coils, such as image 3 As shown, the two sets of coils are completely independent.

[0041]The method of generating the rotating magnetic field: 1) when there is no current in the two groups of coils, the electromagnet has no magnetism; 2) when there is...

Abstract

The invention relates to an intelligent heating agitator and the controlling method, which is applied in heating and agitating experiment in chemical field, especially dangerous chemical experiment and reacting in sealed container. The method comprises: (1) agitating with magnetic drive, isolation of driver and agitator is favor for sealing reacting container and preventing reactant from splashing; (2) putting intelligent controller far away from reacting device, remote controlling to avoid contact with toxic substance; (3) controlling coil and heating plate with intelligent H bridge and power device, which is characterized by smaller volumn and higher stability; (4) integrating agitator with heating device, and the agitating speed, mode, heating temperature are controllable; (5) rotating magnetic field by changing current direction in coil, which is characterized by simpler mechanical structure and flexible control.

Description

technical field [0001] The invention relates to an intelligent heating stirrer and a control method thereof, which are applied to experiments requiring heating and stirring in the field of chemistry, especially chemical experiments where danger exists and reactions occur in sealed containers. Background technique [0002] Heating and stirring are two commonly used methods in chemical experiments to speed up the reaction process. At present, the common implementation method is heating at the bottom and stirring at the top. The easiest way to stir is to hold a glass rod and stir. Under normal circumstances, the above methods can meet the needs, but it is difficult to meet the needs if the following conditions occur: 1) The reaction is violent, and the liquid may splash out and burn the experimenter; The danger of poisoning; 3) The experiment is required to be carried out under sealed conditions. [0003] In order to meet the test requirements when the above three situations...
