[0024] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION
[0025] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] The embodiment of the present application provides a ball mill material ball separation device, which is a device that is convenient for quickly separating grinding balls and residual powder and picking out unqualified grinding balls, thereby reducing the labor intensity of workers and improving work efficiency.
[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0028] The utility model discloses a ball separation device for a ball mill.
[0029] According to the attached Figure 1-3 As shown, it includes a loading mechanism and a screening mechanism;
[0030] The loading mechanism includes a sloping bottom hopper 1, a valve plate 2 and a rapper A3; the sloping bottom hopper 1 has a valve port on the side and the opening and closing is controlled by the valve plate 2, and the rapper A3 is installed on the side wall of the sloping bottom hopper 1;
[0031] The screening mechanism includes a bracket 4, a screening platform, and a waste tray 5; a structure for fixing a slanted bottom hopper 1 is arranged on the top of the bracket 4, the waste tray 5 and the screening platform are placed on the bracket 4, and the waste tray 5 is located below the screening platform.
[0032] This device directly discharges the grinding balls into the inclined bottom hopper 1, eliminating the steps of using a plug-in bucket and an electric hoist to transfer and unload the balls, thereby improving the safety factor. Compared with the valve plate set horizontally in the plug-in bucket, the valve plate 2 set on the side of the inclined bottom hopper 1 can effectively control the material discharge rate, and the vibrator A3 set on the side of the inclined bottom hopper 1 can effectively reduce the occurrence of "bridging" during the ball unloading process.
[0033] Preferably, the inclined bottom hopper 1 and the bracket 4 are movably connected, and the inclined bottom hopper 1 of different specifications can be replaced according to actual conditions.
[0034] Preferably, the angle between the bottom surface of the inclined bottom hopper 1 and the horizontal plane is 20-40°. The inclined bottom hopper 1 has a certain angle, and the position of the discharge port is the lowest, which ensures that all the alloy balls in the inclined bottom hopper 1 can flow out from the discharge port. The angle of the inclined bottom hopper 1 is 20-40°. If the angle is too small, it is relatively flat, and the grinding balls are prone to form a "bridge" effect; if the angle is too large, the effective ball loading capacity of the hopper is reduced, resulting in a large waste of space.
[0035] Preferably, the entire support 4 is welded with steel pipes to ensure the support 4 is capable of bearing heavy objects.
[0036] Preferably, a small platform for placing the waste tray 5 is welded on two parallel horizontal steel pipes.
[0037] Preferably, four universal wheels 7 are installed at the bottom of the bracket 4 to facilitate movement.
[0038] Preferably, the screening platform includes a steel frame, a perforated plate 8, a vibrator B9 and a hopper 6; wherein the perforated plate 8 and the hopper 6 are detachable, the perforated plate 8 is placed on the steel frame, the hopper 6 is located at the bottom of the perforated plate 8, and a vibrator B9 is provided at the bottom of the perforated plate 8; the steel frame is welded to the bracket 4. The grinding balls are separated from the residual powder and the severely worn grinding balls by the perforated plate 8 installed on the bracket 4, wherein the angle between the perforated plate 8 and the horizontal plane is 10-20°, at which angle the grinding balls and the large particles mixed with the materials will roll in one direction under the action of gravity, and accelerate on the perforated plate 8 at the same time; the diameter of the hole of the perforated plate 8 is half of the diameter of the normal grinding balls, and when the grinding balls and the mixed materials pass through the perforated plate 8, the severely worn grinding balls and the mixed materials enter the hopper 6 through the hole, and the normal grinding balls pass over the perforated plate 8 and are collected by the other end of the device. In addition, the rapper B9 provided below the orifice plate 8 can not only prevent the grinding balls from sinking too deeply into the holes and clogging the holes, but can also shake off the powder adhering to the grinding balls, thereby achieving the cleaning of the grinding balls.
[0039] When the device is in use, the universal wheel 7 at the bottom of the bracket 4 is fixed, the inclined bottom hopper 1 is fixed on the bracket 4, and the valve plate 2 is inserted, the grinding balls in the ball mill are poured into the inclined bottom hopper 1, the discharge port valve is opened, and the opening size is adjusted to make the discharge rate appropriate; the vibrator A3 on the inclined bottom hopper 1 is turned on to assist in discharging, and the vibrator B9 under the orifice plate 8 is turned on. The grinding balls and the mixed powder fall on the orifice plate 8 under the action of gravity and roll in one direction on the orifice plate 8 at an accelerated speed. When the grinding balls pass through the holes, the severely worn grinding balls and the mixed powder will enter the receiving hopper 6 from the holes; the powder stuck on the grinding balls will also fall off from the grinding balls due to vibration and fall into the receiving hopper 6 under the orifice plate 8, and finally be collected together on the waste tray 5 through the receiving hopper 6. The grinding balls that can be used normally continue to roll on the orifice plate 8 and are collected at the other end of the device.
[0040] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
