Abstract
The utility model relates to a stirring kettle and adopts the technical scheme as follows: the stirring kettle comprises a tank body, a motor, and a stirring device and internal members thereof, which are arranged inside the tank, wherein the motor is arranged on the tank body through a support, the motor is a permanent magnetic direct-driving motor, and the permanent magnetic direct-driving motor is connected with a frequency converter. The speed reduction unit in the stirring system is not needed, and the asynchronous motor is replaced with the permanent magnetic direct-driving motor, so that the work efficiency and operating cost of the stirring kettle can be greatly increased. The permanent magnetic direct-driving motor is connected with the frequency converter, and the frequency converter enables the motor to have a large start-up torque with a small start-up current. The stirring kettle has the advantages of stable performance and low cost.
Description
Technical field
The utility model belongs to bio-pharmaceuticals equipment field, is specifically related to a kind of stirred tank.
Background technology
Stirred tank is most important equipment in the bio-pharmaceuticals equipment, the tradition stirred tank mainly partly is comprised of automatically controlled part, AC asynchronous motor, reducing gear, tank body and internals etc., wherein asynchronous motor and driving section are the key links of electric energy loss, also are the key links of energy efficiency.
Pharmacy industry stirred tank system adopts the interior material of the mode activated tank of asynchronous machine-reductor-shaft, (be respectively about 80% and about 90% because the efficient of asynchronous machine and reductor is very low, the whole efficiency of this link is about 72%), and exist the series of problems such as power consumption is large, maintenance is frequent, vibrations are large, noise pollution is serious, have a strong impact on the production cost and gain of pharmaceutical factory.
Summary of the invention
The utility model is by the following technical solutions: a kind of stirred tank, comprise tank body, motor, be located at agitating device and other internals in the tank body, motor is set up on the tank body by propping up, and described motor is the permanent magnet direct-drive motor, and the permanent magnet direct-drive motor links to each other with frequency converter.
Stirred tank by decelerator, is adjusted to the required speed of agitator of technological requirement with the rotating speed of motor, drives the shaft rotation by shaft coupling again, thereby drives agitator work.The utility model removes the reductor in the stirring system, asynchronous motor changes the permanent magnet direct-drive motor into, adopt permanent magnet direct-drive electric motor system magneto directly to drive the shaft work of stirred tank, can significantly improve stirred tank operating efficiency and operating cost like this.The permanent magnet direct-drive motor links to each other with frequency converter, and frequency converter can make motor with less starting current, obtains larger detent torque, stable performance, and cost is lower.
Because adopt the power frequency supply power supply can realize stable operation after magneto starts, in order to reduce cost, a frequency converter can be according to actual conditions dragging multiple electric motor starting.Behind the electric motor starting terminal of motor is guided on the electrical network, in the mains supply situation, motor also can efficiently move.
The beneficial effects of the utility model are: the utility model removes the reductor in the stirring system, changes asynchronous motor into the permanent magnet direct-drive motor, can significantly improve stirred tank operating efficiency and operating cost; The permanent magnet direct-drive motor is linked to each other with frequency converter, and frequency converter can make motor with less starting current, obtains larger detent torque, stable performance, and cost is low to adopt this scheme and the energy-conservation at least 15%-20% of former scheme contrast through Conservative estimation.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment,
Among the figure: 1, motor, 2, support, 3, tank body.
The specific embodiment
As shown in the figure, a kind of stirred tank comprises tank body 3, motor 1, and motor 1 adopts the permanent magnet direct-drive motor, is located at agitating device and other internals in the tank body 3, and motor is located on the tank body by support 2, and the permanent magnet direct-drive motor links to each other with frequency converter.Reductor in the stirring system is removed, and asynchronous motor changes the permanent magnet direct-drive motor into, adopts permanent magnet direct-drive electric motor system magneto directly to drive the shaft work of stirred tank, can significantly improve stirred tank operating efficiency and operating cost like this.The permanent magnet direct-drive motor links to each other with frequency converter, and frequency converter can make motor with less starting current, obtains larger detent torque.
