A powder metallurgy pulverizing device

Abstract

The invention discloses a powder making device for powder metallurgy, which is convenient to manufacture, can be used for well controlling gaps of annular seams and enables water flow to be more smooth. The powder making device comprises a supporting base, a flow guiding hopper and a flow guiding pipe, wherein the flow guiding hopper is arranged on the supporting base, the flow guiding pipe is embedded in the supporting base, and a collecting box is arranged under the flow guiding pipe; the supporting base comprises an upper supporting base and a lower supporting base, at least one pair of water inlet passages, an annular arc-shaped guiding spray passage and horn-shaped transition passages are arranged between the upper supporting base and the lower supporting base, the horn-shaped transition passages correspond to the water inlet passages and are communicated with the water inlet passages and the arc-shaped guiding spray passage, the tail end of the arc-shaped guiding spray passage is provided with the annular seams, spray nozzles are formed, and spraying lines of the spray nozzles are gathered on center lines of pipe holes of the flow guiding pipes; the lower supporting base is provided with flow guiding through holes matched with the annular seams, and the flow guiding through holes are positioned in extension pipelines of the flow guiding pipes. The powder making device disclosed by the invention is mainly used for preparing powder metallurgy raw materials.

Description

technical field [0001] The invention relates to a pulverizing device, in particular to a pulverizing device for preparing powder metallurgy raw materials. Background technique [0002] The structure of the traditional powder metallurgy powder making device usually includes: a support, a diversion bucket arranged on the support, and a diversion pipe embedded in the support and communicating with the outlet at the lower end of the diversion bucket. A collection box is arranged under the pipe, and a water inlet channel and an annular direct spray channel connected with the water inlet channel are arranged in the support. Due to the integrated structure of the injection channel, it is difficult to manufacture, especially the precision of the annular slit (nozzle) at the end of the injection channel is not easy to control, thus affecting the injection effect; in addition, because the high-pressure water flow directly enters the annular The injection channel, the flow is not smoo...
