Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in figures 1 and 2, the ball mill with the impurity cleaning function comprises a frame 1, a barrel 2 horizontally arranged on the frame 1 and a driving device 3 for driving the barrel 2 to rotate, wherein a feeding port and a discharging port are respectively arranged at the front side and the rear side of the barrel 2, a plurality of grinding balls are arranged in the barrel 2, the diameter sizes of the grinding balls are the same, a plurality of impurity discharging ports 4 are arranged on a transverse straight line of the annular wall of the barrel 2 at intervals, the impurity discharging ports 4 are formed by communicating small and large two-section through holes inside the impurity discharging ports 4, the lateral middle section of each impurity discharging port 4 is in a convex shape, sealing blocks 5 matched with the sizes of the impurity discharging ports 4 are arranged in the impurity discharging ports 4, the peripheral parts of the impurity discharging ports 4 are made of positive magnets 6, the sealing blocks 5 are made of negative magnets, the sealing blocks 5 are fixed in the impurity discharging ports 4 under the attraction effect of the positive magnets 6 and the negative magnets, a circle of sealing rings 7 is further arranged on the, frame 1 on still be equipped with a lifting strip 8 and be used for driving this lifting strip 8 to carry out the lift drive arrangement of oscilaltion, transverse interval is equipped with a plurality of embedded rods 9 on the lifting strip 8, embedded rods 9 and the position one-to-one of arranging miscellaneous mouthful 4, a trapezoidal hole 10 has still been seted up to the bottom of sealing block 5, the top of embedded rod 9 is equipped with the round platform 11 that matches with trapezoidal hole 10 size, be equipped with positive coil in the round platform 11, the suction that gives sealing block 5 after the circular telegram of positive coil is greater than the magnetic force that positive magnet 6 gave sealing block 5.

At ordinary times, the sealing block 5 is arranged in the impurity discharging port 4, and the ball mill is in a normal working state. When a large amount of impurities are mixed in the cylinder body 2, the impurities need to be cleaned, a certain amount of clean water can be introduced from the material inlet, then the cylinder body 2 is rotated to mix the impurities in the clean water, then the impurity discharging port 4 is aligned with the lower embedded rod 9 up and down, the rotation of the cylinder body 2 is stopped, because a certain gap is formed between the grinding balls, therefore, after the cylinder body 2 is static, the impurities can be precipitated downwards in the clean water under the action of gravity and are precipitated to the peripheral side of the impurity discharging port 4, then the lifting bar 8 is driven to ascend so that the circular truncated cone 11 embedded at the end part of the rod 9 is inserted into the trapezoidal hole 10, then the positive coil is electrified to lead the positive coil to firmly absorb the sealing blocks 5, and then the lifting strip 8 is driven to descend to pull out all the sealing blocks 5, at the moment, because the impurities are positioned at the peripheral side of the impurity discharging port 4, and a large amount of clean water is arranged above the impurity discharging port, and the impurities can be flushed out from the impurity discharging port 4 under the guidance of the clean water.
