[0008] First, the crushed material is transported by a belt conveyor and dropped by an inclined chute. During the falling, the air blown from the back of the inclined chute causes the light-weight material in the crushed material to float and be sucked into the duct. Heavy objects that do not float by the air are immediately dropped and sorted by the inclined chute. For the light-weight material sucked into the duct, a relatively heavy thing is stored in the storage container at the divided suction port provided in the middle of the duct, and the relatively light thing is further sucked into the duct. It will be contained.

It is what left. The particles of the glass powder conveyed by the airflow and sent to the first powder product recovery unit are rebounded by the classifying plate, and the flow of the particles is directed downward. As a result,
The glass particles having a relatively large particle size arrive at the first powdered product recovery section, settle, and are recovered. On the other hand, relatively small particles in the glass powder product pass through the first powder product recovery section in the airflow from the lower passage without settling. The small particles that have passed here are collected and collected by the second powder product collection section. As the second powder product collection unit that collects and collects small particles, for example, a collection device using a centrifugal force such as a cyclone can be used.

The glass powder classifier of the present invention is characterized in that an air flow regulating valve is disposed between the first powder product recovery section and the second powder product recovery section. There is.
In the glass powder product classifying apparatus of the present invention, the air volume is controlled and adjusted mainly by a carrier that generates an air flow. However, since a relatively large resistance to the air flow exists between the transporter that generates the air flow and the first powder product collection unit,
To finely adjust the air volume of the first powder product collection section,
It is not always sufficient to adjust the air volume of the transfer device that generates the air flow. In the present invention, as a result of arranging and adjusting the air flow control valve in the small particle discharge pipe between the first powder product recovery unit and the second powder product recovery unit, fine air flow control is achieved. This makes it possible to finely adjust the particle size of the glass powder product collected in the first powder product collection section.

If the classifying plate is at an angle of less than 45 ° with respect to the horizontal plane, the particles colliding with the classifying plate will not sufficiently stall and will pass through the first powdery product recovery unit. Classification plate is 90 ° to horizontal plane
If it exceeds, the resistance is too large, and small particles are prevented from passing through the first powder product recovery section. For more efficient classification, the angle is preferably 60 to 90 °.

Here, the degree of shielding is the ratio of the area of the classifying plate that blocks the passage to the effective cross-sectional area of the passage when there is no classifying plate. If the degree of shielding is less than 60%, the particles do not stall sufficiently and pass through the first powder product recovery section, and if the degree of shielding exceeds 80%, the resistance is too large, and the small particles are less than the first powder. This will prevent it from passing through the product collection section.

It is preferable that the structure of the classifying plate be simple for maintenance of the apparatus. For this reason,
From the viewpoint of its function, a preferable number of sheets is one each on the inlet side and the outlet side of the first powdery product collecting section.

According to the present invention, if the classification is performed using the glass powder classification apparatus of the present invention to remove small particles and then sieved and classified,
It is possible to prevent clogging of the sieve and to classify the glass powder with high productivity. In addition, since the glass powder classification apparatus of the present invention has a simple and compact structure, it can be configured at low cost, has easy maintenance, and has a low possibility of failure. Further, the air volume can be finely adjusted by an air volume adjusting valve disposed between the first powder product recovery unit and the second powder product recovery unit, and the particle size of the powder product particles to be classified is thereby adjusted. Can be changed finely.
