Description

[Detailed description of the invention] The present invention relates to a gravimetric blending device for powder and granular materials.

Conventionally, in the case of blending equipment for powder and granular materials, a volume increasing machine such as a mass feeder or a mini feeder is used to feed each raw material into the -1 part of a hopper for main raw materials or a hopper for auxiliary raw materials. The desired blending ratio (C by volume) was determined using a weight machine, and the raw materials were supplied to a mixing tank for the next step.

However, in the case of this device, the i-t of the powder and granules to be blended
In order to weigh ffi by the volume of the powder or granules, depending on the size of the various powders or granules used, when placed in n1 parts of the weighing machine,
It is undeniable that an error naturally occurs in the quantity due to the voids between the individual powder particles, and -1: 1:': + degree of W
When lfij precision is required, there is a limit at about C1 in volume level: 1ii(,).

It is a method that continuously performs the mixing process of powder and granules
1. There was a drawback that the mixed raw materials in the mixing tank were not necessarily mixed uniformly, resulting in uneven mixing.

The present invention was developed in consideration of the points described above, and the purpose is to make the powder and granules to be blended more precise than that which would be difficult to obtain with a volume of 81. It is an object of the present invention to provide a device that can perform the following steps and make the mixing state more uniform by performing batch processing in each blending and mixing step. Therefore, the feature of the present invention is that the main raw material hopper is:
A switching machine is installed in the sub/jij: 4" At the same time, a mixing tank with a stirrer installed inside via an opening/closing machine is installed below the separate tank, and below the counterfeit tank. A storage tank with a level detector installed inside is installed via an opening/closing machine, and is further equipped with an arithmetic and control device, and is installed at the bottom of the main raw material hopper using the OIj-OF'to° signal from the level detector. In addition to controlling the opening/closing machine and controlling the weight detection device, supply device, and each opening/closing machine, processing in the pilgrimage tank and mixing tank is carried out in a hatch-like manner. is blended with high precision using a heavy paper device using a weight detection device.
