Embodiment Construction

[0019] Combine below figure 1 , figure 2 with image 3 Introduce the invention in detail:

[0020] The ultrafine dynamic classifying and discharging device of the dry ball milling system includes a hollow cylinder 3 with a discharge port 34 at the bottom end, and a feed pipe 31 for materials to enter the inner cavity of the cylinder on the upper part of the cylinder. The present invention The material is not limited to the material after ball milling, raw material powder is also possible; the lower part of the cylinder is provided with an air inlet pipe 32 for gas to enter the inner cavity of the cylinder, and the negative pressure device arranged at the top of the cylinder makes the outside air flow from the The air inlet pipe 32 enters the inner cavity of the cylinder. The gas entering the inner cavity of the cylinder blows the lighter materials from the bottom up to the top of the cylinder and then flows out. The heavier materials flow from the top to the discharge port 34. ...

Abstract

The invention relates to a dry type ball-milling system and particularly relates to a superfine dynamic graded discharge device for a dry type ball-milling system. The device comprises a hollow cylinder with a discharge port at the bottom end. The discharge port is connected to a discharge mechanism, and materials flowing from the discharge port of the cylinder flow out through the discharge mechanism; the discharge mechanism comprises a base body which is hermetically connected to the discharge port and a discharge wheel which is arranged in the base body and is driven by a motor to rotate, and the materials flowing into the base body from the discharge port are driven by the discharge wheel which rotates to flow out. According to the device provided by the invention, outside gas is inhaled into the graded cylinder by using a negative pressure device. The gas can be used for graded treatment on materials which are relatively light in the graded cylinder and materials which are relatively heavy in the graded cylinder, so that a purpose of improving the quality uniformity of a finished product is achieved; meanwhile, the discharge mechanism is arranged at the discharge port, so that continuous discharge can be realized, and the discharge port can be sealed during feeding at a negative pressure, and therefore, the airtightness in the negative pressure state is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of a classification discharging device and material classification equipment, in particular to a classification discharging device of a dry ball mill system. Background technique [0002] The classification device is a circular air classifier. The head of the existing classifier has a main fan to provide the flow power of the classification air, and an integral shaft drives the main fan, centrifugal disc and axial fan. The material enters the centrifugal disc from the upper end without air seal. The centrifugal disc disperses and distributes the feed material in a radial shape to the peripheral plate. The air flow is accelerated by the combination of the axial fan and the blade ring, and the spiral airflow flows upward to drive the feed. materials. The fine powder is mixed in the air flow, while the coarse material falls downward, and the fine powder mixed in the air flow is transported to the outside of the cla...
