Description

Technical Field

[0001] The utility model relates to the technical field of screening, in particular to a screening device for a ball press. Background Art

[0002] The briquetting machine is a briquetting equipment for processing composite materials such as dephosphorizing slag agent and iron powder. Inside the briquetting machine, there is a pair of rollers with parallel axes, the same diameter and a certain gap between them. There are many hemispherical sockets of the same shape and size and arranged regularly on the rollers.

[0003] For example, a ball press screening device with patent number CN219503191U includes a plurality of material receiving frames and screen plates. The screen plates are arranged tilted downward and are arranged at the discharge port of the ball press. The material receiving frames are arranged below the screen plates. The screening device also includes a motor, a rotating plate, a sliding pipe, and a toggle column. The motor is arranged on a first supporting plate, and its output shaft is connected to one end of the rotating plate. A through hole is arranged at the other end of the rotating plate. The above document still has deficiencies. When in use, after the material is pressed into a ball by the ball press, the spherical material falls from the discharge port of the ball press onto the screen plate. The motor is started to make the screen plate swing slightly left and right. On the one hand, the spherical material moves downward along the tilt of the screen plate, and on the other hand, it moves along with the screen. The plate swings left and right, making the movement trajectory of the spherical material more disordered, prolonging the time that the spherical material stays on the screen plate, increasing the contact opportunity with the screen plate, and improving the screening effect. However, when the above-mentioned ball press screening device is screening the spherical material, the spherical material moves on the screen plate at a faster speed when the screen plate is shaking, and some crushed materials will be mixed with the spherical material and discharged, making the screening effect of the ball press screening device poor. At the same time, when adding spherical materials to the ball press screening device, adding too little spherical material will affect the screening efficiency, and adding too much will affect the screening effect of the spherical material. When screening, it is not convenient to control the amount of spherical material added. Utility Model Content
