Abstract
A frequency converter for a stirring motor of a polyreactor relates to the technical field of the polyreactor. The main body of the frequency converter is a machine body. The frequency converter is characterized in that a control button is arranged on the machine body; an ampere meter is arranged above the control button; and the digital display of the ampere meter is correct to two decimal places. The frequency converter is simple in structure; and the relationship between currents of a stirring motor and corresponding material viscosities is found through a great deal of experiment data of the material viscosities and the currents of the stirring motor under the condition that the stirring rotational speed is fixed. Therefore, the feeding quantity of end-capping reagent can be adjusted promptly by directly referring to a current value to carry out control measures, which effectively controls product viscosity, shortens detection time, and controls and adjusts product viscosity more visually.
Description
Technical field:
The utility model relates to the technical field of polymerization reaction kettle, relates in particular to a kind of frequency transformer of polymerization reaction kettle agitator motor.
Background technology:
RTV Methyl Silicone Rubber (basic glue) uses the ring-opening polymerization under the condition of catalyzer of organosilicon dimethyl siloxane ring body to use distilled water to obtain the poly-methyl sily oxide polymkeric substance of hydroxyl envelope section as end-capping reagent when being called for short the production of 107 glue.Its molecular weight adopts kinematic viscosity to characterize, and kinematic viscosity unit is this, i.e. per second square metre (m
2/ s), and centistoke commonly used in the practical measurement, (cst) unit of expression centistoke is that the per second square millimeter (is 1cst=1mm
2/ s).Its viscosity of product specification commonly used is mainly 3000cst to 10 ten thousand cst, need to use full-bodied product in a lot of occasions now, viscosity 500,000 cst to 100, ten thousand cst even greater than 1,000,000 sct.The production polymerization process comprises that polymerization and decompression take off low two stages of molecule, uses the intermittence type polymerization reactor.
In the prior art, regulate the viscosity of product, to lean against polymerization process to add end-capping reagent and the operating method in order to guarantee that the molecular weight distribution employing repeatedly adds on a small quantity, the frequency that adds is the variation with reference to its viscosity of sampling analysis in the polymerization process, adopt rotational viscosimeter, analysis time, long the detection needed about 40 minutes partially, seriously lagged behind to instructing the production adjusting viscosity.
The utility model content:
Technical problem to be solved in the utility model is to overcome the defective of prior art, and providing a kind of can monitor automatically, in time regulates the frequency transformer of polymerization reaction kettle agitator motor of the add-on of end-capping reagent.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of frequency transformer of polymerization reaction kettle agitator motor, the main body of frequency transformer is body, it is characterized in that: described body is provided with push button, and the top of push button is provided with reometer.
The digital display of described reometer is accurate to 2 significant digits.
Described reometer is located at internal body.
Described frequency transformer is located in the control cabinet for power distribution.
Increase the principle that the agitator motor load increases according to material in reactor viscosity, make the reometer on the frequency transformer of agitator motor into digital display tolerance range high reometer, reometer can be shown to doubly value of 2 significant digits peace.
The utility model is simple in structure, by the viscosity of material under the fixing mixing speed and the electric current of agitator motor have been done a lot of experimental datas, finds out the relation between the viscosity of corresponding agitator motor electric current and material.So just directly reference current value is in time regulated the add-on of end-capping reagent as control device, thereby effectively controls the viscosity of product, has shortened the time of detecting, the viscosity of controlling more intuitively and regulating product.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of frequency transformer of polymerization reaction kettle agitator motor, the main body of frequency transformer is body 1, and body 1 is provided with push button 3, and the top of push button 3 is provided with reometer 2.The digital display of reometer 2 is accurate to 2 significant digits.Reometer 2 is located at internal body.Frequency transformer is located in the control cabinet for power distribution.
Increase the principle that the agitator motor load increases according to material in reactor viscosity, make the reometer on the frequency transformer of agitator motor into digital display tolerance range high reometer, reometer can be shown to doubly value of 2 significant digits peace.By the viscosity of material under the fixing mixing speed and the electric current of agitator motor have been done a lot of experimental datas, find out the relation between the viscosity of corresponding agitator motor electric current and material.So just directly reference current value is in time regulated the add-on of end-capping reagent as control device, thereby effectively controls the viscosity of product.
Above demonstration and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
