Fig. 3 is the figure of an example of the relation between the rotating speed of the output of expression closed mixer 100 and stirring.The longitudinal axis is represented output (kW), and transverse axis is represented rotating speed (rpm).
As shown in Figure 3, in the scope A of output from 0kW to 1000kW, by only making variable speed driver 20 work, stirring rotator 91,92 can turn round to any rotating speed of 20rpm with rotating speed 0rpm.
Then, be output as the 2000kW place, by only making 10 work of constant speed motor, stirring rotator 91,92 can turn round with rotating speed 40rpm.In addition, in the scope C of output from 2000kW to 3000kW, while by making 10 work of constant speed motor, making variable speed driver 20 work, stirring rotator 91,92 can turn round with any rotating speed from rotating speed 40rpm to 60rpm.
In aforesaid method of operation, variable speed driver 20 only is the direction of rotation work of the direction that increases under the situation of constant speed motor 10 with the stirring rotator rotating ratio.If the direction of rotation of variable speed driver 20 is made as the direction opposite with it, then the stirring rotator rotating speed can adjusted than the direction that only is step-down under the situation of constant speed motor 10.If this method is applied to the example of Fig. 3, then based on the work that only is constant speed motor 10, stirring rotator 91,92 turns round with rotating speed 40rpm, with respect to this, by making variable speed driver 20 to opposite spin, can be 0～-scope of 20rpm adjusts rotor speed, therefore, can make stirring rotator 91,92 runnings with any rotating speed from 20rpm to 40rpm.
In the closed mixer 100 of above-described first embodiment, make possessing respectively of mixer 90 send a pair of stirring rotator 91,92 rotations of agitator and reversion agitator by constant speed motor 10, and utilize checkout gear 201 to detect the temperature that is stirred thing, control device 200 is controlled the rotating speed of variable speed driver 20 according to this detection information, thus, can be stirred the stirring of thing with the state of the best.In addition, detection information is not limited to the characteristics such as temperature that are stirred thing in the mixer 90, can comprise cooling water temperature, motor power or their rate of change etc. of mixer.
Particularly, control device 200 is predetermined and is stirred the design temperature that thing becomes set quality, compare by temperature that is stirred thing and design temperature in 201 pairs of closed agitating devices of checkout gear 100, under the low situation of the temperature that is stirred thing, the rotation of variable speed driver 20 is quickened, the temperature that is stirred thing is raise.On the other hand, under the high situation of the temperature that is stirred thing, the rotation of variable speed driver 20 is slowed down, reduce the temperature that is stirred thing.
And then, according to the detection information or the treatment process that are stirred thing etc., except constant speed motor 10, also make variable speed driver 20 work, thereby can easily make the rotation speed change of a pair of stirring rotator 91,92.Thus, can stir being stirred thing according to the physical property that is stirred thing.
For example, be stirred in the stirring of thing and have various treatment process.Therefore, control device 200 carries out following control according to the state that is stirred thing in treatment process or the stirring.
Particularly, under the situation of carrying out masterbatch (master batching) treatment process (for example carbon mixes people's operation) or finished composition (final mixing) treatment process (for example add the sulphur agent and mix people's operation) etc., need make a pair of stirring rotator 91,92 runnings with specific rotating speed.Like this, when wanting to carry out to make the running of rotor rotation of mixer with specific rotating speed, control device 200 is controlled to be rotating speed with steady state (certain rotating speed) rotation with constant speed motor 10, and with variable speed driver 20 be controlled to be from 0 in the variable-ratio scope with certain rotating speed rotation arbitrarily.
And, under the situation of the running (for example controlling) of the rotor rotation of wanting to carry out to make mixer with the rotating speed corresponding with the state that is stirred thing according to the temperature that is stirred thing, perhaps want to prevent under the situation of overload running (for example controlling) based on the temperature that is stirred thing, need on one side according to being stirred the temperature of thing or rotating speed change that variations in temperature makes a pair of stirring rotator 91,92, Yi Bian control.Under this situation, control device 200 is controlled to constant speed motor 10 with constant rotating speed rotation, and variable speed driver 20 changes are controlled to from the 0 rotating speed rotation to expect in the variable-ratio scope.
And, when the closed mixer is discharged when being stirred thing or started other mixer, need to make a pair of stirring rotator 91,92 low loads rotations sometimes.In this case, control device 200 is controlled to constant speed motor 10 and stops the rotation, and only variable speed driver 20 is controlled to from 0 and makes a pair of stirring rotator 91,92 rotations with rotating speed arbitrarily in the variable-ratio scope.
That is, make according to treatment process under the situation of rotation speed change, as shown in Figure 3, because as long as the rotating speed of control variable speed driver 20, so, not only can reduce load, and can make a pair of stirring rotator 91,92 rotations with the optimum speed corresponding with two motors to two motors.As a result, can prevent that the efficient of motor self from reducing, can also use constant speed motor 10 and variable speed driver 20 for a long time.
And, because a pair of stirring rotator 91,92 has the agitator of sending and reversion agitator respectively, so, can give high shear action to being stirred thing with few energy consumption, thus can make different types of polymer and packing material, additive etc. equably mixed melting disperse.
And, because constant speed driven shaft S11 and variable-ratio driven shaft S21 are relatively disposed up and down, so, with constant speed driven shaft S11 and variable-ratio driven shaft S21 by along continuous straight runs side by side the situation of configuration compare, what can reduce closed mixer 100 is provided with area (basal part structure).In addition, be configured to compare, can reduce the height of closed mixer 100 along the situation that vertical is extended with constant speed driven shaft S11 and variable-ratio driven shaft S21.
