Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

Because in the rubber banburying, nanometer calcium, calcium carbonate, carbon black appear weighing unstable three kinds of materials most easily, the utility model discloses mainly improve nanometer calcium feed bin 1, calcium carbonate feed bin 2, carbon black feed bin 3 in to the internal mixer upper auxiliary machine, as shown in figure 1.

1. Nano calcium bin

The nanometer calcium belongs to a nanometer novel material, has light specific gravity, strong material adhesion and poor fluidity, is shown as adhering to the wall of a storage bin in the storage bin, is easy to form a bridge and is easy to form a cavity at the lower part of the storage bin. Therefore, the utility model discloses improve nanometer calcium feed bin, as shown in fig. 2, include: the improvement point of the nano calcium bin lies in the combination of the stirrer 11, the injection pipe 12 and the vibration hammer 13.

Agitator 11 is a spiral agitator, and the agitator motor is installed in the feed bin top, and the feed bin middle part is arranged in to the puddler, and the puddler drives helical blade rotatory under the drive of motor, adopts helical blade can make the interior nanometer calcium of upper and lower direction large tracts of land of feed bin stirred, and the spiral stirring can guarantee that the material glues the wall, does not take a bridge. For nano calcium, the rotating speed is controlled to be about 10 r/min.

And the injection pipe 12 is arranged below the stirrer 11 in the storage bin, and the loosening degree of the materials is improved by arranging the injection pipe. Preferably, the blowing pipe 12 is provided with nozzles 121 in both the upper and lower directions, and may blow upward or downward. Intermittent blowing can be controlled.

The vibration hammer 13 is installed on the side wall outside the storage bin, and the storage bin is knocked in a vibration mode to prevent materials from adhering to the wall of the storage bin. The vibration hammer can also be intermittently hammered.

2. Calcium carbonate feed bin

The light calcium carbonate has high specific gravity, and is easy to form a stacking bridge in the storage bin, and once the light calcium carbonate is formed, the stacking bridge cannot be eliminated, so that the screw conveying device 4 at the bottom of the storage bin is easy to operate in an overload mode. Therefore, the improvement scheme to the calcium carbonate feed bin is: as shown in fig. 3, in order to reduce the material flow speed in the storage bin, the lower part in the storage bin is provided with the striker plates 21 which are inclined downwards along the circumference of the inner wall, generally the inclined downwards inclination angle is 45 degrees, the centers of the striker plates are not closed, and proper gaps are left at the centers to ensure that the materials fall down; in addition, a blowing pipe 22 is also arranged above the striker plate, and the nozzle faces the striker plate, so that materials are prevented from being deposited on the striker plate and are always in a suspended state. Simultaneously, to the calcium carbonate feed bin, the outside does not use the vibrations hammer.

3. Carbon black feed bin

The granulated carbon black has good fluidity, and even if the screw conveyor 4 does not rotate, the carbon black can flow freely, which easily causes the material to be weighed overweight. Therefore, the improvement of the carbon black silo is that firstly, a baffle 31 is additionally arranged in a spiral groove of the screw conveying device 4 connected with the silo and close to the discharge end, as shown in fig. 4, the baffle 31 is annularly arranged around the main shaft, the upper end of the baffle is connected with the upper cover of the screw conveying device 4, the lower end of the baffle is suspended, and a part of channel is reserved for the material to flow. The baffle blocks most of the conveying channel of the screw conveying device 4, so that the flowability of the screw conveying device is hindered; secondly, a blowing pipe 32 is arranged at the lower part in the storage bin, so that the loosening degree of the materials is improved, and the fluidity of the materials is reduced, as shown in figure 5. Also, for calcium carbonate silos, no vibratory hammer is used externally.

Through improving the feed bin to above-mentioned three kinds of materials, can destroy the material and bridge, make the even whereabouts of material, prevent the material because of the dead weight compaction with prevent the material fast flow. Meanwhile, the upper unpacking fan 5 is changed into a variable-frequency fan, the running frequency of the variable-frequency fan is adjusted, and the lifting caused by negative pressure can be reduced; the unloading valve 6 is additionally arranged at the tail end of the induced draft pipeline, and the negative pressure of the system can be controlled by adjusting the weight of the valve core.
