Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Fig. 1-4 show a dry ball mill convenient for operation, which comprises a base 1, a frame 2 slidably mounted on the base 1 up and down, a ball mill cylinder 3 rotatably mounted on the frame 2, and a driving mechanism mounted on the frame 2 for driving the ball mill cylinder 3 to rotate. The base 1 and the frame 2 described above are not limited to the form of construction shown in fig. 1 and 2. The cross section of the ball mill cylinder 3 in the above is a circular structure. The ball mill cylinder 3 rotates around its own axis on the frame 2, and the rotational mounting manner is a conventional technique in the prior art, and usually, both ends of the ball mill cylinder 3 are rotatably mounted on the frame 2 through bearings. Supporting springs 11 are distributed between the base 1 and the frame 2, and the supporting springs 11 are used for supporting the frame 2 and providing upward elastic force to drive the frame 2 to move upward. The top of the ball mill cylinder 3 is provided with a feed opening 32, from which the material enters the interior of the ball mill cylinder 3. A lid body 7 is mounted on the throat to open and close the throat 32. The cover body 7 is connected with the ball mill cylinder 3 through a flange. The bottom of the ball mill cylinder 3 is provided with a screen 31. The screen 31 is of an arc structure, is made of stainless steel material, has fine small holes, and is firmly welded with the ball mill cylinder 3. A material receiving groove is arranged below the screen mesh 31 on the base 1. The finely ground material particles may fall through the screen 31 into the holding tank 12. A graduated scale 5 is vertically arranged on one side of the base 1, a horizontal pointer 51 is arranged on the rack 2, and one end of the pointer 51 points to the graduated scale 5. Through above-mentioned structural design, when throwing the material into ball mill barrel 3, under the action of gravity, frame 2 and ball mill barrel 3 are whole to be moved down, and then pointer 51 more moves along with down to operating personnel can read out the addition of current material from scale 5.

In order to prevent the screen 31 from being blocked by some material particles, a cross bar 6 is arranged above the inner part of the ball mill cylinder 3, the length direction of the cross bar 6 is the same as the axial direction of the ball mill cylinder 2, and bristles 61 are distributed and arranged on the cross bar 6. The brush staples 61 are made of stainless steel material. One end of the brush 61 far away from the cross rod 6 is attached to the inner wall of the ball mill cylinder 3. The outer side of ball mill barrel 3 is coaxially provided with a rotating shaft 62, one end of the rotating shaft 62 is movably penetrated into the ball mill barrel 3 and is connected with the cross rod 6, and the other end of the rotating shaft 62 is fixedly connected with the frame 2 through a connecting piece. In order to avoid the interference of the rotating shaft 62 and the cross bar 6 with the grinding processing of the materials as much as possible, the cross bar 6 is as close as possible to the upper inner wall of the ball mill cylinder 1. A connecting rod is connected between the end part of the rotating shaft 62 entering the ball mill cylinder 3 and the cross rod 6, and the connecting rod is also close to the inner wall of the ball mill cylinder 3 as much as possible. In order to improve the use effect, a bearing 63 is arranged between the rotating shaft 62 and the ball mill cylinder 3. In addition, a dustproof framework sealing ring 64 is arranged between the rotating shaft 62 and the ball mill cylinder 3 to prevent the materials from overflowing to the outer side of the ball mill cylinder 3. Through the above structural design, when the ball mill cylinder 3 rotates, when the screen 31 rotates to the upper side, on one hand, the material leaves the screen under the action of gravity, and on the other hand, the bristles 61 can clear away the residual material on the screen 31.

The driving mechanism is in the prior art and comprises an outer gear ring 4, a driving motor 42 and a driving gear 41, wherein the outer gear ring 4 is sleeved on the outer surface of the ball mill cylinder 3. The driving motor 42 is fixed on the frame 2, the driving gear 41 is fixed on the power output shaft of the driving motor 42, and the driving gear 41 is meshed with the outer gear ring 4.

In order to prevent the ball mill cylinder from idling after the material grinding is completed, a contact switch 52 is installed on the scale 5, the contact switch 52 is installed above the pointer 51 and corresponds to the upper end surface of the pointer 51, and the upper end surface of the pointer 51 can touch the contact switch 52 when the pointer 51 moves upward. The base 1 is provided with a controller 8, and the driving mechanism and the contact switch 52 are respectively electrically connected with the controller 8. In particular, the drive motor 42 of the drive mechanism is connected to the controller 8. The controller 8 receives the signal output from the contact switch 52 and controls the driving mechanism to stop operating. The control of the controller 8 is conventional in the art. To improve the usability, the contact switch 52 is slidably mounted up and down on the scale 5 and fixedly connected to the scale 5 by a set screw. Thus, the height of the contact switch 52 can be adjusted to meet the requirements of different material grinding production and processing. Through the above structural design, the material of grinding is collected by receiving silo 12, and the whole gravity of ball mill barrel 3, frame 2 etc. reduces, and under supporting spring 11's spring action, whole upward movement such as ball mill barrel 3, frame 2, and then pointer 51 follows upward movement to can touch contact switch 52, and then control driving motor 42 outage stop work through controller 8. The contact switch 52 may be a proximity sensor.

During the use, material and grinding ball enter into the inside of ball mill barrel 3 through feed inlet 32, and under the action of gravity, whole downwardly moving such as ball mill barrel 3, frame 2, pointer 51 follows the downstream, and operating personnel can observe the addition of material in real time through observing scale 5 that pointer 51 points to. When the standard value is reached, the addition of the material is stopped, and the feed opening 32 is closed by the lid body 7. The height of the contact switch 52 may or may not be adjusted as desired. Then the driving motor 42 is started to operate, the driving motor 42 drives the ball mill cylinder 3 to rotate for grinding, and when the screen 31 rotates to the lower part, the ground materials fall into the receiving groove 12 below through the screen 31. So simultaneously, the whole weight of ball mill barrel 3, frame 2 etc. reduces, and under the spring action of supporting spring 11, ball mill barrel 3, frame 2 etc. wholly upwards move, and pointer 51 follows upwards to move, and when the material grinds to finish, pointer 51 rises to the highest point and touches contact switch 52, and controller 8 receives the signal of contact switch 52 output to control driving motor 42 stop motion, ball mill barrel 3 stall. Further, the brush staples 61 contact the inner wall of the ball mill cylinder 3 during the rotation of the ball mill cylinder 3, and perform the cleaning work on the screen mesh 31.

This embodiment uses through scale 5 and pointer 51's cooperation, and operating personnel can conveniently observe the add volume of material very much through pointer 51 directional scale 5, has effectively overcome the material and has added too much or the problem that comes too little time, has improved the utilization ratio of ball mill, has avoided the waste of resource. On the other hand, after the material grinds and accomplishes, through pointer 51 and contact switch 52's cooperation use, the ball mill can in time automatic shutdown, has effectively improved the life of ball mill, and has avoided the waste of resource, the simple operation, the practicality is strong.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all utilize the equivalent structure or equivalent flow transformation that the content of the specification does, or directly or indirectly use in other related technical fields, all including in the same way the patent protection scope of the present invention.
