Description

Technical Field

[0001] The invention relates to the technical field of disc pelletizing machines, and in particular to a disc pelletizing machine used in a rotary hearth furnace for treating metallurgical solid waste. Background Art

[0002] The disc ball making machine is a device for making raw balls in the pellet production process. Its structure consists of a rotating spindle structure. The disc of the ball making machine is supported on the main shaft. The main shaft is hinged to the supporting shaft of the equipment base at the two front fulcrums. The end of the spindle box is connected to the base through an inclination adjuster. Its working principle is that the peripheral disc on the machine body is inclined at an angle of 30-55 degrees to the horizontal, which can be adjusted arbitrarily within the specified range. The motor drives the disc to rotate through a gear reducer and a pair of bevel gears. The disc is equipped with a water spray pipe and a scraper plate. After the powder is added into the disc and moistened by water, it rolls continuously to form particles-small balls-large balls. When the small balls continue to roll larger toward the middle of the disc, they roll to the edge of the disc and are discharged.

[0003] However, the existing disc pelletizing machine has a pelletizing barrel which is not easy to disassemble and install, and the existing water spray pipe can only be heated locally or by manual pulling, which has poor uniformity and high labor cost. Summary of the invention

[0033] A scraper mechanism 3 is provided inside the pelletizing cylinder 2. The scraper mechanism 3 is existing and its two sides are mounted on a fixed plate 14 through telescopic rods in order to adjust its height and avoid interference when the pelletizing cylinder 2 is replaced.

[0034] Example 2

[0035] Based on Example 1, please refer to Figure 4-5As shown, a telescopic support frame 4 is provided on the fixed plate 14. The setting of the telescopic support frame 4 is to facilitate the adjustment of its height.

During the pelletizing process, the servo motor 2 42 is started to drive the screw to rotate, thereby driving the sliding sleeve 44 to move. The sliding sleeve 44 will drive the guide sleeve to move during its movement. During the movement of the guide sleeve on the guide rod 43, the push column 46 will be continuously squeezed by the setting of the wave groove 412 and the push column 46, and the seesaw 48 will be continuously driven to rise and fall under the action of the spring 1 47, thereby driving the drive shaft 410 to rotate back and forth through the rocker arm 49, and the drive shaft 410 drives the nozzle 411 to swing back and forth, thereby spraying water into the pelletizing barrel 2.
