Technical Field

The invention belongs to the technical field of non-ferrous metal smelting, and particularly relates to a ball press.

Background

In the pyrometallurgical process of non-ferrous metals, in order to strengthen the smelting process and improve the smelting environment, raw materials are pretreated before entering the smelting process. Feedstock briquetting is one way of feedstock pretreatment. At present, in a pyrometallurgical treatment process, lump coal or coke is used as a reducing agent, so that the reduction effect is poor, and the content of valuable metals in tailings is high. In the process of preparing the pellet reducing agent, due to the properties of raw materials, the briquetting rate of the ball press is low, and the analysis results show that on one hand, pellets formed by the ball press pair rollers directly fall onto a conveying belt, so that part of the pellets are damaged, the working efficiency of the ball press is low, on the other hand, the pellets are damaged more, the generated powder is increased, the powder needs to be returned again for briquetting, the labor intensity is increased, and meanwhile, the mixed hemisphere in the returned material also affects the working efficiency of the ball press.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a ball press machine for improving the balling rate.

The invention is realized by the following technical scheme.

A ball press machine, characterized in that, ball press machine includes: the device comprises a machine shell (1), a ball pressing roller pair, a sliding plate (2), a conveyor belt (3) and a screen (4); the ball pressing roller pair and the sliding plate (2) are both arranged in the machine shell (1), the conveyor belt (3) is positioned below the sliding plate (2), and the output end of the conveyor belt extends out of the machine shell (1); the ball pressing roller pair comprises two oppositely arranged ball pressing rollers (5), the sliding plate (2) is obliquely arranged below the ball pressing roller pair, and the lower end of the sliding plate (2) is close to the output end of the conveying belt (3); the screen (4) is obliquely arranged, the upper end of the screen (4) is connected with the output end of the conveyor belt (3), and the lower end of the screen (4) is connected with the finished product bin (6); the top of casing (1) is equipped with feed inlet (7), the lower extreme of feed inlet (7) is aimed at between two ball rollers (5).

Further, slide (2) include upper segment board (8), lower section board (9), upper segment board (8) are located the one side of press ball roller pair, the lower extreme of upper segment board (8) is connected with the upper end of lower section board (9), lower section board (9) are the rectangle board of slope setting, the rectangle board is located two press ball rollers (5) under.

Further, the length of the rectangular plate is larger than the sum of the diameters of the two ball pressing rollers (5).

Furthermore, the upper end and the lower end of the sliding plate (2) are fixed on the inner wall of the machine shell (1).

Further, a powder bin (10) is arranged below the screen (4).

Furthermore, the bottoms of the machine shell (1) and the conveyor belt (3) are supported by a support rod (11).

Further, the section of the feed inlet (7) is trapezoidal.

The invention has the beneficial technical effects that: (1) the slide can make the ball roller transport to the conveyer belt fast to the pelletizing of die-casting, improves ball machine work efficiency. (2) The sliding plate is arranged below the ball pressing roller in alignment, the pellets are not easy to damage through the buffering of the sliding plate, and slide down along the sliding plate by the gravity of the sliding plate, so that the pelletizing rate of the ball pressing machine is improved. (3) The screen cloth at the output end of the conveyor belt enables the pellets to be directly separated from the powder, so that the labor intensity is reduced, and the working efficiency is greatly improved.
