Abstract
A novel stirring device consists of a magnetic stirrer, a stirring motor, a disc and a casing and is characterized in that the disc is fixed on a drive shaft through a locking screw in the casing, the drive shaft is connected with a drive motor through a speed reducer, a magnetic sheet is fixed on the disc, the magnetic stirrer is arranged at the position corresponding to the disc right above the casing, and an elongated permanent magnet is arranged inside the magnetic stirrer. The novel stirring device has the advantages of being installed on a water quality on-line monitoring device and being capable of quickly stirring a solution evenly. The novel stirring device is suitable for a permanganate index analysis instrument, an ammonia gas sensing electrode instrument, an ion-selective electrode instrument and other analysis instruments.
Description
Technical field:
The utility model belongs to agitating device, is specifically related to the magnetic stirring apparatus that a kind of monitoring water quality on line equipment is used.
Background technology:
Present domestic monitoring water quality on line equipment such as permanganate index, ammonia gas-sensing electrode instrument, ion-selective electrode instrument etc., nearly all be unable to do without agitating device, mixing speed, mixing effect etc. all can directly affect the precision of apparatus measures, therefore, online agitating device is particularly important in on-line monitoring equipment, directly affect the reliability of monitored data, relate to the normal operation of device systems.
Summary of the invention:
The purpose of this utility model is to propose a kind of stirring apparatus, can be installed on the monitoring water quality on line equipment, and solution is stirred.
The technical scheme that the utility model proposes is, a kind of stirring apparatus, formed by magnetic stir bar, stirring motor, disk and shell, in the enclosure, disk is fixed on the driving shaft by lock-screw, and driving shaft is connected with drive motors by decelerator, is fixed with magnetic plate at disk, corresponding disk position is provided with magnetic stir bar directly over shell, and magnetic stir bar inside is provided with microscler permanent magnetic iron.
For generation of magnetic field, form rotating excitation field at the fixing magnetic plate of disk under the drive of motor, the induced magnetism stirrer rotates, and the motor front end arranges deceleration device, is used for stabilized speed, strengthens moment of torsion.
The advantage of the stirring apparatus that the utility model proposes is, is installed on the monitoring water quality on line equipment, can fast solution be stirred.Be applicable to permanganate index, ammonia gas-sensing electrode instrument, ion-selective electrode instrument etc. and analyze the agitating device of instrument.
