DETAILED DESCRIPTION

[0017] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0018] A slag processing grinding device, such as Figure 1-Figure 3As shown, it includes a fixed frame 1, a first motor 2, a transmission rod 3, a connecting frame 4, a grinding wheel 5, a cone 6, a scraper 7, a grinding chamber 8, an air duct 9, a grinding ring 10, a fixed plate 11, an air duct 12, a second motor 13, a capture wheel 14, a feed hopper 15, a gate 16 and a fan 17. The upper part of the fixed frame 1 is connected to the first motor 2, the output shaft of the first motor 2 is connected to the transmission rod 3, the upper part of the transmission rod 3 is connected to the connecting frame 4, a plurality of grinding wheels 5 are rotatably connected to the connecting frame 4, the transmission rod 3 is connected to the cone, the lower part of the cone 6 is connected to the scraper 7, and the fixed frame 1 is connected to the first motor 2. A grinding chamber 8 is connected to the top of the fixed frame 1, an air duct 9 is provided at the bottom of the grinding chamber 8, a grinding ring 10 is connected to the inner side of the lower part of the grinding chamber 8, the grinding wheels 5 are in contact with the grinding ring 10, a plurality of fixed plates 11 are connected to the inside of the air duct 9, an air duct 12 is connected to the top of the grinding chamber 8, a second motor 13 is connected to the top of the air duct 12, a capture wheel 14 is connected to the output shaft of the second motor 13, a feed hopper 15 is connected to the right side of the upper part of the grinding chamber 8, a gate 16 is slidably connected to the feed hopper 15, a fan 17 is connected to the left side of the lower part of the grinding chamber 8, and the air outlet end of the fan 17 is connected to the air duct 9.

[0019] Working principle: When the utility model is in use, the gate 16 is first opened to guide the slag from the feed hopper 15 into the grinding chamber 8, and the slag introduced into the grinding chamber 8 is manually guided by the cone 6, so that the slag is dispersed at the bottom of the grinding chamber 8, and then the first motor 2 is started, and the output shaft of the first motor 2 rotates to drive the transmission rod 3 to rotate, and the transmission rod 3 rotates to drive the connecting frame 4, the grinding wheel 5, the cone 6 and the scraper 7 to rotate, and the scraper 7 scoops up the slag at the bottom of the grinding chamber 8 and transmits it upward, so that the slag is aligned with the position of the grinding wheel 5. Since the grinding wheel 5 is in a rotating state, the grinding wheel 5 can cooperate with the grinding ring 10 to grind the slag. The slag is ground into powder, and then the fan 17 is started. The fan 17 supplies air to the inside of the air duct 9. The input airflow is guided by the fixed plate 11 and blown into the grinding chamber 8, so that the powdered slag in the grinding chamber 8 that meets the particle size requirements can be lifted up, while the slag that does not meet the particle size cannot be lifted up, and is continued to be guided by the scraper 7 and ground and crushed in cooperation with the grinding wheel 5. The powdered slag floats upward in the grinding chamber 8, and then the second motor 13 is started. The output shaft of the second motor 13 rotates to drive the capture wheel 14 to rotate, and the capture wheel 14 captures the slag powder of the required particle size and guides it into the air duct 12, and then it is guided out by the air duct 12.
