Examples

As shown in fig. 1-2, the baking soda powder metering and blanking device comprises a material containing chamber 1, a material distributing chamber 2 and a blanking chamber 3, wherein the material containing chamber 1 is used for containing baking soda powder to be blanked, the material distributing chamber 2 is used for metering and blanking the baking soda powder, and the blanking chamber 3 is used for containing baking soda powder in a certain amount so as to convey the baking soda powder to the next equipment. The arrangement of the upper structure and the lower structure reduces the occupied area of the whole blanking device and avoids the influence on the placement of other devices in a factory.

When the baking soda powder particles are ground, the grinding rate can be improved by grinding for multiple times, so that the powder quality is uniform. There is a high demand for the quantity of baking soda particles entering the mill, which can affect the grinding effect if too much or less baking soda particles are added at a time. And this function of the unable swift convenient realization of current unloader structure measures, and often can take place the unloading and block up, has influenced the grinding operation in later stage. So said the utility model discloses an improve the convenience of unloader when using, made certain improvement to the structure of material compartment 2 for whole unloader can convenient and fast realize the measurement unloading of baking soda powder.

Specifically, the material containing chamber 1 is funnel-shaped, the top of the material containing chamber is provided with a feeding port, the lower part of the material containing chamber is provided with a discharging port, the material distributing chamber 2 is positioned at the lower part of the material containing chamber 1 and is in a transverse cylindrical shape, the top of the material containing chamber is provided with an opening 21 to be communicated with the discharging port of the material containing chamber 1, so that baking soda powder particles to be discharged in the material containing chamber 1 fall into the material distributing chamber 2, and the opening 21 and the discharging port are connected in a fixed mode such as welding. The bottom of the distribution chamber 2 is provided with a distribution drop opening 22 so that falling sodium bicarbonate particles can drop into the blanking chamber 3 below the distribution chamber 2 in a sub-amount.

The material distribution chamber 2 is internally provided with a material distribution rotary table 4, and the rotary table 4 is in a transverse cylindrical shape and is coaxially arranged with the material distribution chamber 2, namely the outer wall of the rotary table 4 faces the inner wall of the material distribution chamber 2. A plurality of partition plates 6 are fixed on the side wall of the rotary table 4 at intervals along the axial direction of the rotary table, and the partition plates 6 are welded and fixed with the side wall of the rotary table 4. The partition boards 6 are equal in length to the side walls thereof, the other side walls of the partition boards 6, which are not fixed with the rotary disc 4, are tightly abutted against the inner wall of the material distributing chamber 2, and the spacing distances among the partition boards 6 are the same. In this way, a funnel-shaped receiving cavity 41 with the same volume can be formed between two adjacent partition boards 6.

Furthermore, the end face of the rotating disc 4 is also connected with a driving device 5, in this embodiment, the driving device 5 is a variable frequency motor, the variable frequency motor is arranged on the outer wall of the material distribution chamber 2, an output shaft of the variable frequency motor extends into the material distribution chamber 2 through a through hole formed in the side wall of the material distribution chamber 2 to be connected with the end face of the rotating disc 4, and the variable frequency motor is connected with an external power supply through a power line. The output shaft of the driving device 5 can drive the rotating disc 4 to rotate after being electrified.

When the material distribution is needed, baking soda powder particles to be discharged are filled into the material containing chamber 1, and the driving device 5 is electrified, so the baking soda powder particles to be discharged in the material containing chamber 1 respectively fall into the containing cavities 41 along with the rotation of the rotating disc 4, and because the other end surfaces of the partition plates 6 are close to the inner wall of the material distributing chamber 2, when the containing chamber filled with baking soda powder particles rotates far away from the opening 21 of the material distributing chamber 2, the protruding powder particles accumulated at the opening of the containing chamber cannot rotate along with the containing chamber due to the blockage of the inner wall of the material distributing chamber 2, and are moved to the adjacent containing chambers which are not separated from the opening 21 of the material distributing chamber 2, namely, the equivalent rate of the volume of the baking soda powder particles in each containing chamber is improved. And with the continuous rotation of the rotating disc 4, when the accommodating cavity 41 only to be filled with the baking soda particles rotates to the position of the material distributing falling opening 22 of the material distributing chamber 2 along with the rotating disc 4, at this time, the partition plate 6 is not abutted against the inner wall of the material distributing chamber 2, the end opening of the accommodating chamber has no obstacle, and the baking soda particles in the accommodating chamber can fall into the lower blanking chamber 3 through the material distributing falling opening 22. As shown in fig. 3, the port of the a-chamber communicates with the divided material dropping port 22, and at this time, all the baking soda particles inside can drop due to gravity. When the rotating disc 4 continues to rotate, the port of the B accommodating chamber is gradually not blocked by the side wall of the material distributing chamber 2 and is communicated with the material distributing falling port 22, and the baking soda particles in the B accommodating chamber fall into the blanking chamber 3 along with the baking soda particles. So, at the unloading in-process, each unloading is the volume that holds in the chamber 41, has realized the quick measurement unloading, has improved whole unloader's convenience. And by adopting the mode of the multiple blanking, the defect of blanking blockage of the whole device in the blanking process can be avoided, and the blanking speed is improved.

Parts not described in the above modes can be realized by adopting or referring to the prior art.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
