Description

Technical Field

[0001] The invention belongs to the technical field of material crushing, and in particular relates to a coarse material ball mill. Background Art

[0002] Ball mill is the key equipment for crushing materials after they are broken. It is widely used in the production of cement, clay for flower arrangement, silicate, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation, glass and ceramics, etc., and in the steel industry.

[0003] The existing ball mill uses a low-speed rolling drum to lift the grinding balls in the drum under centrifugal force, and then fall and hit the block materials at the bottom of the drum to crush the block materials. In this process, the rolling grinding balls will also rub and collide with the materials to crush them.

[0004] In the existing ball mill, after the material is put into the drum, the rotating drum and the internal grinding balls crush the material, and then the material is discharged from the discharge screw device. However, since some large pieces of material do not effectively contact the grinding balls when they move in the drum, the particle sizes of the crushed materials are different, and the material is often not broken. It is necessary to screen the material after discharge, and put the unbroken large particles into the device again for crushing, which reduces the overall work efficiency and requires repeated ball milling, which is time-consuming and labor-intensive. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a coarse material ball mill, which solves the problem that when the existing ball mill is crushing the material, large particles of material are not crushed and discharged and need to be filtered again, and the re-crushing work is inefficient, time-consuming and labor-intensive.

[0006] The technical solution adopted to solve the above technical problems is: comprising a ball mill, the side inner wall of the ball mill is movably connected with an insert block, the side surface of the insert block is fixedly connected with a mounting plate, the side inner wall of the mounting plate is movably connected with a magnetic filter, the side surface of the magnetic filter is threadedly connected with a screw 1, the lower surface of the insert block is fixedly connected with a damping universal joint, and the side inner wall of the damping universal joint is rotatably connected with a rotating rod;

[0007] A filter screen is movably connected to the inner side wall of the mounting plate, two screws are threadedly connected to the side surface of the filter screen, a number of steel balls are movably installed between the filter screen and the magnetic filter screen, a discharge pipe and a feed pipe are fixedly connected to the two ends of the ball mill respectively, bearings are interference-connected on the side surfaces of the discharge pipe and the feed pipe, and a mounting frame is fixedly connected to the side surface of the bearing.

[0008] Through the above technical scheme, when the ball mill 1 crushes the material, the filter screen and the magnetic filter screen installed in the mounting plate can double block the large particles that have not been completely crushed, so as to avoid the large particles from being discharged from the device without being crushed, resulting in the need to filter and screen the material in the later stage, and put the uncrushed material into the device again for crushing, and the mounting plate can be taken out from the ball mill, and the filter screen and the magnetic filter screen with different pores can be replaced according to production needs to improve the practicality of the device, and after taking out, the iron balls in the ball mill and the steel balls installed between the filter screen and the magnetic filter screen can be taken out and replaced, and the magnetic filter screen can filter the material and absorb the iron ball debris worn by long-term use to avoid affecting the purity of the material when it is discharged, and the steel balls and the rotating rods can hit the surface of the filter screen to vibrate and fall the material attached to the filter screen, so as to avoid the filter screen being blocked and affecting the use of the device.

[0009] Furthermore, the side surface of the mounting plate is movably connected to the ball mill, the upper surface of the mounting plate is fixedly connected with a handle, the side surface of the screw 1 is threadedly connected to the mounting plate, and the magnetic filter is made of neodymium iron boron material.

[0010] Through the above technical solution, the mounting plate and the plug can be taken out of the ball mill by providing a fulcrum for the hand with the handle. The magnetic filter made of NdFeB material has adsorption properties, which can adsorb iron filings and adsorb screws 1 and 2 on the surface after they fall off, so as to prevent the fallen screws 1 and 2 from being discharged with the material and mixed in the material.

[0011] Furthermore, the side surface of the second screw is threadedly connected to the mounting plate, the side surface of the ball mill is fixedly connected to the fixing plate, the side surface of the insert block is fixedly connected to the connecting rod, the upper surface of the fixing plate is fixedly connected to the bolt, a plurality of iron balls are movably connected inside the ball mill, and the side inner wall of the ball mill is fixedly connected to a guide bevel block.

[0012] Through the above technical solution, a number of iron balls collide with the guide inclined block at the high point during the rotation of the ball mill and fall to hit the materials in the ball mill, so that the materials are crushed.

[0013] Furthermore, a nut is threadedly connected to the side surface of the bolt, the bolt passes through the connecting rod, and a connecting plate is fixedly connected to the side surface of the mounting plate, and the bolt passes through the connecting plate.

[0014] Through the above technical solution, the connecting plate and the connecting rod can be installed on the fixing plate by means of bolts and nuts, thereby limiting the installation of the mounting plate and the insert block.

[0015] Furthermore, a discharging screw is fixedly connected to the inner side wall of the discharging pipe, a feeding screw is fixedly connected to the inner side wall of the feeding pipe, and a feeding box and a discharging guide plate are fixedly connected to both ends of the mounting frame.

[0016] Through the above technical solution, the discharging screw can transport the screened materials during rotation so that they are discharged from the device, and the feeding screw can transport the materials put into the feeding box into the ball mill during rotation.

[0017] Furthermore, a transverse plate is fixedly connected to the side surface of the mounting frame, and a power mechanism is fixedly connected to the upper surface of the transverse plate.

[0019] Furthermore, the power mechanism includes a motor, a coupling and a reducer, the motor is fixedly connected to the cross plate, the motor and the input end of the reducer are fixedly connected through the coupling, and the output end of the reducer is fixedly connected to a bearing rod.

[0020] Furthermore, a support seat is fixedly connected to the side surface of the mounting frame, a pinion is fixedly connected to the side surface of the bearing rod, and the side surface of the bearing rod is rotatably connected to the support seat.

[0021] Through the above technical solution, the small gear transmits force to the large gear during rotation, so that the large gear drives the ball mill to rotate.

[0022] Furthermore, a large gear is fixedly connected to the side surface of the ball mill, and the side surface of the large gear is meshed with the small gear.

[0023] The beneficial effects of the present invention are as follows:

[0024] (1) The detachable mounting plate and plug-in block on the ball mill make the whole in a sealed state when installed, and the iron balls in the ball mill can be taken out when removed, so that the worn iron balls can be taken out and replaced;

[0025] (2) The magnetic filter and filter installed in the mounting plate can filter the crushed materials in the ball mill, so that larger uncrushed materials cannot pass through, thereby avoiding the discharge of materials before they are completely crushed, resulting in the need for re-screening and returning for crushing later, thereby improving the working efficiency of the device. The filter and magnetic filter installed by screws 1 and 2 can be replaced with magnetic filters and filter screens with pores of different diameters according to production needs, thereby increasing the practicality of the device;

[0026] (3) The magnetic filter can absorb the iron ball debris that is worn out during long-term use while filtering the material, preventing the iron debris from being discharged with the material and affecting the purity of the material. When the filter is damaged, the device can still filter the material, preventing the large particles from being directly discharged when the filter is damaged.

[0027] (4) When the filter is damaged, the steel ball installed between the magnetic filter and the filter will crush the large particles when they enter between the filter and the magnetic filter. The steel ball will cooperate with the rotating rod that keeps changing direction to hit the filter during rotation to hit the surface of the filter to prevent the pores on the surface of the filter from being blocked by the material, which would affect the use of the device.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0037] like Figure 1-Figure 7As shown, a coarse material ball mill of this embodiment includes a ball mill 1, and an insert block 2 is movably connected to the side inner wall of the ball mill 1. After the insert block 2 is taken out of the ball mill 1, a hole of the same size as the insert block 2 is formed on the ball mill 1, and the iron ball 17 in the ball mill 1 can be taken out from the hole, or the iron ball 17 can be put into the ball mill 1 to avoid the wear of the iron ball 17 during long-term use, which will cause the pulverizing effect of the device to deteriorate. The side surface of the insert block 2 is fixedly connected to a mounting plate 3, and the side inner wall of the mounting plate 3 is movably connected to a magnetic filter 4 The magnetic filter 4 can filter the material to prevent large particles from being discharged directly, and cooperates with the filter 9 to form a double filter. When the filter 9 is damaged, the device still has a filtering function. The side surface of the magnetic filter 4 is threadedly connected with a screw 5. When the screw 5 is used, the magnetic filter 4 can be removed from the mounting plate 3 or installed on the mounting plate 3. The magnetic filter 4 with different apertures can be replaced according to production needs. The side surface of the mounting plate 3 is movably connected to the ball mill 1, and the upper surface of the mounting plate 3 is fixedly connected with a handle 6. When taking out the mounting plate 3 and the plug block 2, a fulcrum is provided for the hand. The side surface of the screw 5 is threadedly connected to the mounting plate 3. The magnetic filter 4 is made of NdFeB material. The magnetic filter 4 made of NdFeB material has a magnetic adsorption function, which can adsorb the debris of the iron ball 17 under wear to prevent the debris from being directly discharged with the material and affecting the purity of the material. The lower surface of the plug block 2 is fixedly connected with a damping universal joint 7. The damping universal joint 7 makes the rotation angle of the rotating rod 8 installed inside multi-directional. When the ball mill 1 rotates, the rotating rod 8 can rotate in multiple directions, and the inner side wall of the damping universal joint 7 is rotatably connected with the rotating rod 8. The multi-directionally rotating rotating rod 8 can change the movement trajectory of the iron ball 17 when it contacts the iron ball 17 that has displaced to a high point, so that the landing point of the iron ball 17 is changed, thereby avoiding the iron ball 17 having the same movement trajectory and the same landing point, which increases the crushing effect of the iron ball 17. When the iron ball 17 contacts and collides with the filter screen 9 during rotation, the filter screen 9 is vibrated to avoid the pores on the surface of the filter screen 9 being blocked by materials and affecting the use of the device.

[0038] The side inner wall of the mounting plate 3 is movably connected with a filter screen 9, which can block the uncrushed large particles in the ball mill 1, so that the large particles can be crushed by multiple impacts, thereby improving the crushing effect of the device and avoiding the problem that the discharged materials contain large particles and need to be screened again for crushing. The side surface of the filter screen 9 is threadedly connected with a screw 2 10, through which the filter screen 9 can be removed and installed, and filters 9 of different apertures can be installed according to production needs, thereby increasing the practicality of the device. A number of steel balls 11 are movably installed between the filter screen 9 and the magnetic filter screen 4. The steel balls 11 can hit the filter screen 9 and the magnetic filter screen 4 when they fall during rotation to avoid their blockage. At the same time, if the filter screen 9 is damaged and large particles pass through the filter screen 9, the steel balls 11 will hit the filter screen 9 and the magnetic filter screen 4. The ball 11 can impact and crush large particles of materials. The side surface of the screw 10 is threadedly connected to the mounting plate 3. The side surface of the ball mill 1 is fixedly connected to the fixing plate 12. The side surface of the insert block 2 is fixedly connected to the connecting rod 14.

The side inner wall of the ball mill 1 is fixedly connected to a guide bevel block 18. When the ball mill 1 rotates and the iron ball 17 moves to a high position and impacts with different positions of the guide bevel block 18, the iron ball 17 impacts downward. The side surface of the bolt 15 is threadedly connected to the nut 16. The bolt 15 penetrates the connecting rod 14. The side surface of the mounting plate 3 is fixedly connected to the connecting plate 13. The bolt 15 penetrates the connecting plate 13. The mounting plate 3 can be fixedly connected to the fixing plate 13 by the bolt 15 and the nut 16. The mounting plate 3 and the insert block 2 are fixedly installed on the ball mill 1. The two ends of the ball mill 1 are fixedly connected with a discharge pipe 19 and a feed pipe respectively. The side surfaces of the discharge pipe 19 and the feed pipe are interference-connected with bearings 21. The side surface of the bearing 21 is fixedly connected with a mounting frame 22. The mounting frame 22 can support the ball mill 1 so that the ball mill 1 is away from the ground. The inner wall of the discharge pipe 19 is fixedly connected with a discharge screw 20. The discharge screw 20 rotates with the rotation of the ball mill 1. During the rotation, the material displaced to the discharge pipe 19 is transported so that the material is discharged from the device. The inner wall of the feed pipe is fixedly connected with a feed screw. The two ends of the mounting frame 22 are fixedly connected with a feed box 23 and a discharge guide plate 24 respectively. The material to be crushed can be put into the ball mill through the feed box 23. 1. The discharge guide plate 24 guides the discharged material. The side surface of the mounting frame 22 is fixedly connected with a transverse plate 25. The upper surface of the transverse plate 25 is fixedly connected with a power mechanism 300. The power mechanism 300 includes a motor 26, a coupling 27 and a reducer 28. The motor 26 is fixedly connected to the transverse plate 25. The input end of the motor 26 and the reducer 28 is fixedly connected through the coupling 27. The connection method of the motor 26, the coupling 27 and the reducer 28 is the existing technology. The motor 26 is electrically connected to the external power supply through its own connecting wire. The output end of the reducer 28 is fixedly connected with a bearing rod. The side surface of the mounting frame 22 is fixedly connected with a support seat 30. The side surface of the bearing rod is fixedly connected with a pinion 29. The side surface of the bearing rod is rotatably connected with the support seat 30.A large gear 31 is fixedly connected to the side surface of the ball mill 1, and the side surface of the large gear 31 is meshed with the small gear 29.

[0039] The working principle of this embodiment is as follows: when installing the magnetic filter 4 and the filter 9, unscrew the nut 16, take out the mounting plate 3 and the plug block 2 from the ball mill 1 through the handle 6, install the magnetic filter 4 on the end of the mounting plate 3 away from the plug block 2 through the screw 1 5, put the steel ball 11 in the mounting plate 3, use the screw 2 10 to install the filter 9 on the end of the mounting plate 3 away from the magnetic filter 4, install the mounting plate 3 into the ball mill 1, pass the bolt 15 through the connecting plate 13 and the connecting rod 14, screw the nut 16 on the bolt 15, and when the ball mill 1 is in use, put the material from the feed box 23, start the motor 26 so that the power of the motor 26 rotates the small gear 29 through the coupling 27 and the reducer 28, and then the large gear 31 drives the ball mill 1 to rotate, and the material enters through the feed pipe and the feed spiral In the ball mill 1, the iron ball 17 and the material rotate in the ball mill 1 when the ball mill 1 rotates. When the iron ball 17 rotates and moves to a high place in the ball mill 1, it falls and hits the material to crush the material. The crushed small particles will pass through the filter screen 9 and the magnetic filter screen 4 in turn and be discharged from the discharge pipe 19 under the action of the discharge screw 20. The large particles will be blocked by the filter screen 9 to increase the crushing time. In the rotation of the ball mill 1, the rotating rod 8 will produce multi-directional rotation, and contact with the iron ball 17 during the rotation to change its displacement. When the filter screen 9 is knocked during the rotation, the material attached to the filter screen 9 is knocked to make it fall off. When the ball mill 1 is rotating, the steel ball 11 hits the material passing through the filter screen 9, and the magnetic filter screen 4 can adsorb the worn iron ball 17 debris mixed in the material.
