Abstract
The utility model provides a constant temperature magnetic stirrers, including agitator body, constant temperature board, electric heating member and temperature sensor, the constant temperature board passes through the bracing piece and sets up in the top of agitator body along the horizontal direction is fixed, and the lower terminal surface of constant temperature board be recess formula structure, and in electric heating member and temperature sensor all set up the recess of terminal surface under the constant temperature board, and the middle part of constant temperature board and edge all correspond and be provided with temperature sensor, and the lower extreme of constant temperature board still is provided with the baffle of terminal surface recess under the closed board with constant temperature. In order solving current constant temperature heating agitator when the heating, the constant temperature board of beaker is placed to the agitator upper end, and temperature difference is very big everywhere when using, and it is great that this just leads to be heated temperature and actual the desiring everywhere of beaker bottom to heat temperature difference, very big to the influence of experiment, not the problem that requires of coincidence experiment. The utility model belongs to the chemistry experiment field.
Description
Technical field
This utility model relates to a kind of agitating device, belongs to chemical experiment field.
Background technology
Existing heated at constant temperature agitator is when heating, temperature is monitored in the temperature sensor being provided above stretching in beaker at agitator by support, but we have found that in actual use, the temperature-constant plate temperature contrast the most everywhere of agitator upper ends beaker is very big, this results in beaker bottom heating temperature everywhere and differs greatly with actual desire heating-up temperature, impact on experiment is very big, does not meets requirement of experiment.
Summary of the invention
The purpose of this utility model is: provide a kind of constant temperature blender with magnetic force, to solve existing heated at constant temperature agitator when heating, the temperature-constant plate temperature contrast the most everywhere of agitator upper ends beaker is very big, this results in beaker bottom heating temperature everywhere and differs greatly with actual desire heating-up temperature, impact on experiment is very big, the problem not meeting requirement of experiment.
For solving the problems referred to above, intend using such a constant temperature blender with magnetic force, including agitator body, temperature-constant plate, electric heating element and temperature sensor, temperature-constant plate is fixedly installed on the top of agitator body in the horizontal direction by support bar, the lower surface of temperature-constant plate is groove type structure, electric heating element and temperature sensor may be contained within the groove of temperature-constant plate lower surface, and the middle part of temperature-constant plate and edge are all correspondingly arranged on temperature sensor, the lower end of temperature-constant plate is additionally provided with the baffle plate closing temperature-constant plate lower surface groove；
For avoiding the too high agitator body to lower section of temperature-constant plate temperature to impact, being additionally provided with thermal insulative board between agitator body and temperature-constant plate, described thermal insulative board is the most transversely arranged, and thermal insulative board is fixed also by they sup-port.
For ensureing thermal insulation effect, described temperature-constant plate is disc-shaped structure, and thermal insulative board is identical with the structure of temperature-constant plate, and the two vertically overlaps；
Preferably, described electric heating element is disc-shaped structure so that each spot temperature of temperature-constant plate is more uniformly distributed；
For improving the service life of temperature-constant plate, it is ensured that product quality, the outer surface of temperature-constant plate is coated with high temperature resistant, anti-oxidation protective coating；
Magnetic stir bar drive system it is additionally provided with, to realize magnetic stirring function in the groove of temperature-constant plate lower surface；
This utility model is compared with prior art, major advantage is the downside that temperature sensor is arranged at temperature-constant plate by this constant temperature blender with magnetic force, rather than be hung in the beaker above temperature-constant plate by support in use and carry out thermometric, temperature-constant plate temperature everywhere can be monitored in real time, avoid the problem that local temperature difference is excessive, ensure beaker bottom heats actual heating requirements everywhere that be more uniformly distributed and meet experiment so that it is meet the associated specifications of thermostatic mixer, it is ensured that the accuracy of experiment.
