Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The present invention provides a technical solution: As Figures 1 to 4 shown, in this embodiment, an abrasive device for refractory material production includes a base 2. Both ends of the upper surface of the base 2 are respectively fixedly connected with mounting frames 3. A ball milling cylinder 1 is arranged between the two mounting frames 3. A sealing cover 10 is arranged at the feed port of the ball milling cylinder 1. Both ends of the ball milling cylinder 1 are respectively fixedly connected with connecting shafts 4. The two connecting shafts 4 respectively penetrate through the two mounting frames 3 and are respectively rotatably connected with the two mounting frames 3. A communication hole 5 communicating with the inside of the ball milling cylinder 1 is opened at the axis center of the connecting shaft 4. A driving mechanism acting on the ball milling cylinder 1 is arranged on the base 2. A cleaning mechanism acting on the inner wall of the ball milling cylinder 1 is arranged inside the ball milling cylinder 1. The cleaning mechanism is composed of a central shaft 11, a movable rod 13, a wiping block 14, a support rod 15 and a movable plate 18. A plurality of movable rods 13 are rotatably connected to the end of the central shaft 11. The plurality of movable rods 13 are arranged in a circular array. A wiping block 14 is fixedly connected to the end of the movable rod 13. A support rod 15 is rotatably connected to the middle of the movable rod 13. The other ends of the plurality of support rods 15 are all rotatably connected with slide blocks 16. The plurality of slide blocks 16 are arranged in a circular array on the outer surface of the movable plate 18 and are fixedly connected with the movable plate 18. An activity groove slidably fitted with the movable plate 18 is opened at the axis center position of the central shaft 11. An adjusting mechanism acting on the movable plate 18 is arranged inside the activity groove. A plurality of slide grooves 17 respectively slidably fitted with the plurality of slide blocks 16 are also opened on the outer wall of the central shaft 11.

[0021] Among them, the adjusting mechanism is composed of an adjusting member 12 and a lead screw 19. The lead screw 19 is rotatably installed inside the central shaft 11. The lead screw 19 penetrates through the movable plate 18 and is connected with the movable plate 18 through a threaded fit. An adjusting member 12 is rotatably connected to one end of the central shaft 11 away from the movable rod 13. The adjusting member 12 is rotatably connected with the lead screw 19.

[0022] During use, rotating the adjusting member 12 drives the lead screw 19 to rotate. However, the movable plate 18 is restricted by the slider 16 and cannot rotate. When the lead screw 19 rotates, the movable plate 18 will slide within the movable groove, thereby driving the support rod 15 to move. The movement of the support rod 15 will drive the movable rod 13 to swing, thus adjusting the inclination angle of the movable rod 13.

[0023] Wherein, a plurality of anti-slip slots are provided on the outer surface of the adjusting member 12, and the plurality of anti-slip slots are arranged in an annular array.

[0024] By providing the plurality of anti-slip slots, the frictional force between the user's hand and the adjusting member 12 can be increased.

[0025] Wherein, the driving mechanism is composed of a motor 6, a fixed vertical plate 7, a driving gear 8 and an external gear 9. The bottom of the motor 6 is fixedly connected to the side end of the base 2 through a fixing plate. The end of the output shaft of the motor 6 is fixedly connected to a driving gear 8. An external gear 9 meshing with the driving gear 8 is fixedly connected to the outer wall of the ball mill cylinder 1.

[0026] During use, start the motor 6 to drive the driving gear 8 to rotate, thereby driving the external gear 9 to rotate, and then controlling the rotation of the ball mill cylinder 1.

[0027] Wherein, one end of the driving gear 8 away from the motor 6 is rotatably connected to a fixed vertical plate 7, and the bottom of the fixed vertical plate 7 is fixedly connected to the base 2.

[0028] By providing the fixed vertical plate 7, the stability of the rotation of the driving gear 8 can be provided.

[0029] Wherein, the diameter of the driving gear 8 is smaller than the diameter of the external gear 9.

[0030] With such a setting, the driving gear 8 and the external gear 9 will form a force-saving gear set, thereby reducing the stress on the motor 6 and effectively increasing the service life of the motor 6.

[0031] The present utility model provides an abrasive device for refractory material production, and the specific working principle is as follows:

[0032] When the ball mill cylinder 1 is working, it is necessary to use a sealing plug to block the communication holes 5 on the two connecting shafts 4. The working principle of the ball mill cylinder 1 is a conventional prior art and will not be described in detail here. When the work of the ball mill cylinder 1 is completed and the inside of the ball mill cylinder 1 needs to be cleaned, remove the sealing plug in the communication hole 5.

[0033] The rotation adjusting member 12 drives the lead screw 19 to rotate. However, the movable plate 18 is restricted by the slider 16 and cannot rotate. When the lead screw 19 rotates, the movable plate 18 will slide in the movable groove, thereby driving the support rod 15 to move. The movement of the support rod 15 will drive the movable rod 13 to swing, thereby adjusting the inclination angle of the movable rod 13, causing the movable rod 13 to fall towards the central axis 11 to bundle the movable rod 13. At this time, the central axis 11 can be inserted into the interior of the ball mill cylinder 1 along the communication hole 5, and then the adjusting member 12 is rotated in the reverse direction to make the movable rod 13 stand up, thereby controlling the diameter of the ring formed by the plurality of wiping blocks 14, so that the plurality of wiping blocks 14 are all abutted against the inner wall of the ball mill cylinder 1. Then, the motor 6 is started to drive the driving gear 8 to rotate, thereby driving the outer gear 9 to rotate, and then controlling the ball mill cylinder 1 to rotate and reciprocally pumping the central axis 11, so as to quickly complete the internal cleaning work of the ball mill cylinder 1.

[0034] It should be noted that due to the obstruction of the support rod 15, the wiping block 14 cannot complete the wiping of the inner wall of the ball mill cylinder 1. This problem can be solved by inserting the central axis 11 from both ends of the ball mill cylinder 1 respectively.

[0035] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
