Abstract

The invention discloses a magnetic stirring device for chemical experiment. The magnetic stirring device comprises a base, wherein a driving motor is mounted inside the base; a magnetic chassis is connected with the output end of the driving motor; a vertical column is fixed on one side of the upper end surface of the base; the vertical column is sleeved by a U-shaped fixing sleeve; a fixing studis screwed with the outer end of the U-shaped fixing sleeve; a transverse rod is fixedly connected with the side wall of the U-shaped fixing sleeve; a thermocouple is fixedly connected with the otherend of the transverse rod through a locking mechanism; clamps are distributed at two ends above the magnetic chassis; heating jackets are tightly adhered to the inner walls of the clamps; sliding rodsare fixedly connected with the lower ends of the clamps; chutes are formed in two sides of the top surface of the base; the lower ends of the sliding rods are connected with corresponding chutes in asliding manner; outer thread structures are distributed at the lower ends of the sliding rods; locking handles are screwed with the outer thread structures; the lower ends of the locking handles aretightly propped against the top surface of the base and are fixed. By adopting the magnetic stirring device, the problems that a conventional magnetic stirring device cannot be rapidly and uniformly heated and is in lack of fixing clamping mechanisms are solved.

Description

technical field [0001] The invention relates to the technical field of chemical instruments, in particular to a magnetic stirring device for chemical experiments. Background technique [0002] The magnetic stirring device drives the magnetic stirrer through the permanent magnet located under the working disk, the permanent magnet can penetrate the surface of the working disk, and the magnet is directly fixed on the rotating shaft of the motor. The actual speed of the instrument depends on the actual load and voltage. The fluctuation of the voltage within the allowable range and the change of the viscosity of the treated medium will cause the fluctuation of the speed. The speed of the motor can be adjusted according to the requirements of the experiment. The general heating magnetic stirrer is equipped with a heating device on the chassis. In addition, a corresponding device will be installed to monitor the heating. A temperature sensor (thermocouple) will be installed on the...
