Description

Technical Field

[0001] The present application relates to the field of tile manufacturing, and in particular to a ball mill for grinding tile raw materials. Background Art

[0002] Ball mill is a commonly used grinding equipment, widely used in mining, building materials, metallurgy, chemical industry and other industries. It is mainly used for the process of crushing and mixing materials.

[0003] A ball mill consists of a horizontal drum, hollow feed and discharge shafts, and a grinding head. The drum is a long, cylindrical structure containing grinding media. Made of steel plate, it is secured to the drum with a steel liner. The grinding media are typically steel balls, though steel segments can also be used. Material is fed into the drum through the hollow shaft at the feed end. As the drum rotates, the grinding media, due to inertia, centrifugal force, and friction, cling to the drum liner and are carried away by the drum. When carried to a certain height, they are thrown down due to their own gravity, and the falling grinding media acts like a projectile, crushing the material inside the drum.

The shield is located outside the passive and active gears. The bottom of the shield is connected to the lubricating oil tank. The lubricating device is connected to the power unit. The lubricating device's oil inlet is connected to the lower part of the lubricating oil tank, and the lubricating device's oil outlet extends to the upper side of the meshing point between the passive and active gears. The lubricating device lubricates the meshing point between the active and passive gears, extending their service life and making the equipment more stable. The shield allows recovered lubricating oil to flow back into the lubricating oil tank, thereby recycling the lubricating oil and avoiding lubricating oil waste.

[0005] Thermal insulation ceramic tiles require a certain particle size for the raw materials. Only when the particle size meets the requirements can the tiles be made to a good quality. However, ball mills cannot measure the particle size of the raw materials during grinding, making it impossible to determine whether the raw materials have been ground to the required size. Summary of the Invention

[0006] In order to facilitate the observation of the size of raw material particles and to facilitate the judgment of whether the raw material particles are ground to a qualified size, the present application provides a ball mill for grinding tile raw materials.

[0007] The present application provides a ball mill for grinding tile raw materials, which adopts the following technical solution:

[0008] A ball mill for grinding tile raw materials includes a frame and a body, the body is rotatably connected to the frame, a accommodating chamber is provided in the body, one end of the body is connected to a rotating shaft, the rotating shaft is provided with a through hole, the through hole is connected to the accommodating chamber, the other end of the body is connected to a feed pipe, a grinding body and a discharging mechanism are provided in the accommodating chamber, the discharging mechanism is used to input the ground raw material particles into the through hole, a first interception net is provided in the through hole for blocking the grinding body, a first filter net is provided below one end of the rotating shaft, the first filter net is used to filter unqualified raw material particles.

[0009] By adopting the above technical solution, the tile raw material is input into the accommodating chamber from the feed pipe, the rotation of the machine body drives the grinding body to move, the grinding body can crush the raw material, and the crushed raw material particles are input into the through hole through the discharging mechanism, and the raw material particles are output from the rotating shaft to the first filter screen. The first filter screen filters the crushed raw material particles. When there are more raw material particles remaining on the first filter screen, the raw material particles are not ground to the qualified size. When there are no raw material particles remaining on the first filter screen, the raw material particles are ground to the qualified size. It is convenient to observe the size of the raw material particles, so as to judge whether the raw material particles are ground to the qualified size.

[0010] Preferably, the accommodating chamber includes a first grinding chamber and a second grinding chamber, the first grinding chamber and the second grinding chamber are spaced apart along the length direction of the body through a second filter screen, the second filter screen is connected to the inner wall of the body, the discharging mechanism is located in the second grinding chamber, the feed pipe is connected to the first grinding chamber, the through hole is connected to the second grinding chamber, the grinding body includes a plurality of large balls and a plurality of small balls, several of the large balls and several of the small balls are located in the first grinding chamber, and several of the small balls are located in the second grinding chamber, the body is tilted and one end of the body connected to the rotating shaft is lower than one end of the body connected to the feed pipe.

[0011] By adopting the above technical solution, the raw material input from the feed pipe first enters the first grinding chamber, the large ball and the small ball first grind the raw material, and when the raw material is ground to a size that can pass through the second filter, it enters the second grinding chamber, and the small ball further grinds the ground raw material particles. The discharging mechanism inputs the raw material particles ground in the second grinding chamber into the rotating shaft, and the raw material particles are transported from the rotating shaft to the first filter for filtration. In this way, it is possible to avoid discharging raw materials with particles that are too large from the machine body as much as possible, and the efficiency of judging whether the raw material particles are ground to a qualified size can be improved.

[0012] Preferably, the discharging mechanism includes a first tube, a second tube and a flexible ring, one end of the first tube is rotatably connected to one side of the second filter screen, the other end of the first tube is connected to one end of the flexible ring, one end of the second tube is connected to the other end of the flexible ring, the other end of the second tube is rotatably connected to the end wall of the body and the pipe mouth faces the through hole, the second tube is provided with a long hole, the length direction of the long hole is consistent with the length direction of the second tube, the width of the long hole is smaller than the diameter of the ball, and the end of the first tube away from the flexible ring and the end of the second tube away from the flexible ring are both provided with a second interception net for blocking the ball.

[0013] By adopting the above technical solution, when the machine body rotates, it drives the raw material particles and the small balls in the second grinding chamber to move, and the raw material particles can be thrown to the long hole and enter the second tube. At the same time, the small balls are thrown to the bottom of the first tube or the second tube or the flexible ring, so that the end of the second tube away from the rotating shaft can be higher than the end of the second tube close to the rotating shaft, and the collision of the small balls with the first tube or the second tube or the flexible ring can vibrate the second tube, which can facilitate the output of the raw material particles in the second tube from the second tube to the rotating shaft. The second interception net can prevent the small balls from entering the first tube and the second tube.

[0014] Preferably, a plurality of blocking bars are provided on the inner wall of the second tube, the length direction of the blocking bars is consistent with the width direction of the second tube, and the blocking bars are evenly spaced along the length direction of the second tube.

[0015] By adopting the above technical solution, when the raw material particles enter the second tube and are transported to the rotating shaft, the blocking bar can block smaller raw material particles, and the blocking bar has a poor blocking effect on larger raw material particles. Therefore, larger raw material particles can be easily input from the second tube into the rotating shaft, which can improve the efficiency of determining whether the raw material particles are ground to a qualified size.

[0016] Preferably, a buffer layer is provided on the outer wall of the first tube and the outer wall of the second tube.

[0017] By adopting the above technical solution, when the ball hits the first tube and the second tube, the buffer layer can play a buffering role, thereby reducing the damage caused by the ball hitting the first tube and the second tube, and the buffer layer can reduce the wear of the raw material particles on the first tube and the second tube.

When the first filter screen rotates in the collection barrel, the raw material particles accumulated in the middle of the first filter screen can be dispersed, thereby facilitating the filtration of the accumulated raw material particles through the first filter screen, thereby improving the filtration efficiency of the first filter screen, and allowing qualified raw material particles to be input into the collection barrel as much as possible, leaving unqualified raw material particles on the first filter screen, thereby improving the efficiency of judging whether the raw material particles are ground to a qualified size.

[0021] By adopting the above technical solution, the rotating rod drives the vertical rod to rotate through the connecting rod, and the vertical rod drives the first filter screen to rotate. When the first filter screen rotates, the support plate moves in the annular groove. When the support plate moves to the protrusion, the support plate moves along the inclined surface to the top of the protrusion, the first filter screen and the vertical rod rise, and when the support plate moves along the inclined surface from the top of the protrusion to the bottom of the annular groove, the first filter screen and the vertical rod descend, so that the first filter screen can be raised and lowered during rotation, thereby vibrating the first filter screen, avoiding clogging of the first filter screen as much as possible, and facilitating the qualified raw material particles to pass through the first filter screen.

[0022] Preferably, a limiting ring is connected to the top of the first filter screen, the central axis of the limiting ring is collinear with the central axis of the first filter screen, the bottom end of the limiting ring is connected to the first filter screen, and the outer wall of the top end of the limiting ring contacts the inner wall of the ring groove.

[0023] By adopting the above technical solution, when the first filter screen rotates to disperse the raw material particles, the limiting ring can prevent the raw material particles from being thrown out of the first filter screen and entering the annular groove, thereby minimizing the raw material particles from affecting the rotation of the first filter screen.

[0024] Preferably, a blocking ring is connected to the top of the limiting ring, the central axis of the blocking ring is collinear with the central axis of the limiting ring, and the cross-section of the blocking ring is arc-shaped with the concave arc surface facing the first filter screen.

[0025] By adopting the above technical solution, when the rotation speed of the first filter screen is accelerated, the raw material particles can be thrown to the blocking ring, and the raw material particles can fall to the top of the first filter screen along the concave arc surface of the blocking ring, thereby vibrating the first filter screen, avoiding clogging of the first filter screen as much as possible, and facilitating the qualified raw material particles to pass through the first filter screen.

[0026] Preferably, a plug is provided in the through hole, the peripheral wall of the plug contacts the inner wall of the through hole, one end of the plug protrudes from the rotating shaft and is connected to a connecting disk, and the connecting disk is detachably connected to one end of the rotating shaft by a bolt.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The tile raw material is input into the accommodating chamber through the feed pipe, and the rotation of the machine body drives the grinding body to move. The grinding body can crush the raw material. The crushed raw material particles are input into the through hole through the discharging mechanism, and the raw material particles are output from the rotating shaft to the first filter screen. The first filter screen filters the crushed raw material particles. When a large amount of raw material particles remain on the first filter screen, the raw material particles are not ground to the qualified size. When no raw material particles remain on the first filter screen, the raw material particles are ground to the qualified size. It is convenient to observe the size of the raw material particles to facilitate judgment of whether the raw material particles are ground to the qualified size.

[0030] 2. When the machine body rotates, it drives the raw material particles and small balls in the second grinding chamber to move, and the raw material particles can be thrown to the long hole and enter the second tube. At the same time, the small balls are thrown to the bottom of the first tube, the second tube, or the flexible ring, so that the end of the second tube away from the rotating axis is higher than the end of the second tube close to the rotating axis. The small balls collide with the first tube, the second tube, or the flexible ring, which vibrates the second tube, and the raw material particles in the second tube can be easily output from the second tube to the rotating axis. The second interception net can prevent the small balls from entering the first and second tubes.

[0046] Reference Figure 1 and Figure 3 The body 101 is cylindrical and tilted, with the feed pipe 103 connected to the higher end of the body 101, and the rotating shaft 102 connected to the lower end of the body 101. The central axes of the feed pipe 103, the body 101, and the rotating shaft 102 are all collinear. A accommodating chamber 200 is provided within the body 101, and the rotating shaft 102 has a through hole that communicates with the accommodating chamber 200. A second filter 203 is provided in the accommodating chamber 200, and the second filter 203 is connected to the inner wall of the body 101. The accommodating chamber 200 includes a first grinding chamber 201 and a second grinding chamber 202, which are spaced apart along the length of the body 101 through the second filter 203. The first grinding chamber 201 is connected to the feed pipe 103, and the second grinding chamber 202 is connected to the rotating shaft 102.

[0047] The grinding body 300 is housed within the machine body 101. The grinding body 300 comprises a plurality of large balls 301 and a plurality of small balls 302, both of which are steel balls. The plurality of large balls 301 and small balls 302 are distributed within the first grinding chamber 201, while the plurality of small balls 302 are distributed within the second grinding chamber 202. Raw material enters the first grinding chamber 201, where the large balls 301 and small balls 302 initially grind the material. After the raw material is ground to particles that can pass through the second filter 203, it enters the second grinding chamber 202, where the small balls 302 further grind the raw material particles.

[0048] Reference Figure 3 and Figure 4The second grinding chamber 202 is provided with a discharge mechanism 400, which comprises a first tube 401, a second tube 402, and a flexible ring 403. Both the first tube 401 and the second tube 402 are square tubes. One end of the first tube 401 is provided with a bevel and is rotatably connected to one side of the second filter 203. The end of the first tube 401, away from the second filter 203, is located within one end of the flexible ring 403, which is a long rubber ring. One end of the second tube 402 is provided with a bevel and is rotatably connected to one end of the inner wall of the machine body 101. The end of the second tube 402 rotatably connected to the inner wall of the machine body 101 is close to the rotating shaft 102, and the opening of the second tube 402 faces the through hole. The inclined ends of the first and second tubes 401, 402 are connected to a second interception net 405, which prevents the ball 302 from entering the first and second tubes 401, 402. The outer walls of the first and second tubes 401, 402 are covered with a rubber cushioning layer. The end of the second tube 402, away from the rotation axis 102, is located within the other end of a flexible ring 403. The flexible ring 403 wraps around the ends of the first and second tubes 401, 402, and the ends of the first and second tubes 401, 402 are connected to the inner wall of the flexible ring 403. The ends of the first and second tubes 401, 402 connected to the flexible ring 403 sag due to gravity.

[0049] The second tube 402 has elongated holes 404 defined on both sidewalls and the top wall. The length of the elongated holes 404 coincides with the length of the second tube 402. The diameter of the balls 302 is greater than the width of the elongated holes 404, minimizing the risk of the balls 302 entering the second tube 402. A plurality of triangular prism-shaped blocking bars 406 are disposed within the second tube 402. These blocking bars 406 are connected to the bottom wall of the second tube 402 and have a length that coincides with the width of the bottom wall. The cross-section of the blocking bars 406 is a right triangle, with the inclined surfaces of the blocking bars 406 facing the opening of the second tube 402.

[0050] Reference Figure 3 and Figure 5 A first interception net 104 is connected to one end of the inner wall of the through hole near the second tube 402. The first interception net 104 is used to prevent the small balls 302 from entering the through hole. A plug 105 is inserted into the through hole. The plug 105 is cylindrical and has a connecting disk 106 connected to one end. The outer wall of the plug 105 contacts the inner wall of the through hole. The connecting disk 106 is located at the end of the rotating shaft 102 away from the first interception net 104. A bolt is inserted into the connecting disk 106, which is threadedly connected to the end of the rotating shaft 102 via the bolt.

[0051] Reference Figure 3 and Figure 6A collection bucket 501 is located below one end of the rotating shaft 102. The collection bucket 501 is cylindrical and open at the top, with the rotating shaft 102 opening toward the top of the collection bucket 501. An annular groove 502 is defined on the inner wall of the top of the collection bucket 501, extending through the top of the collection bucket 501. A first filter 500 is rotatably mounted within the collection bucket 501. The first filter 500 is conical in shape, with its tip at the bottom and facing the bottom of the collection bucket 501. Multiple support plates 503 are circumferentially spaced at equal angles. There are four support plates 503, all arranged horizontally and located on the bottom wall of the annular groove 502.

[0052] A limit ring 512 is connected to the top of the first filter 500. This is a circular ring, with its bottom end connected to the top of the first filter 500. The top diameter of the limit ring 512 is larger than the bottom diameter, and the outer peripheral wall of the top of the limit ring 512 contacts the inner wall of the annular groove 502. A blocking ring 513 is connected to the top of the limit ring 512. The top of the blocking ring 513 is arc-shaped, with the concave surface facing the first filter 500. The center axes of the limit ring 512, the blocking ring 513, and the first filter 500 are all collinear.

[0053] A vertical rod 506 is connected to the bottom of the first filter screen 500. Vertical rod 506 is a round rod, and its central axis is collinear with the central axis of the first filter screen 500. A plug-in slot 507 is defined at the bottom of vertical rod 506, and its length is aligned with that of vertical rod 506. A connecting slot 508 is defined on the inner wall of plug-in slot 507, and its length is aligned with that of plug-in slot 507. A rotating rod 509 is inserted through plug-in slot 507, and a driving member 511 is connected to the bottom of rotating rod 509. Driving member 511 is a motor, and the output shaft of the motor is connected to the bottom of rotating rod 509. A connecting rod 510 is connected to the side wall of rotating rod 509, and its length is aligned with that of rotating rod 509. Rotating rod 509 is inserted into plug-in slot 507, and connecting rod 510 is inserted into connecting slot 508.

[0054] The bottom wall of the annular groove 502 is connected to a plurality of protrusions 504. There are four protrusions 504 and they are distributed at equal angles along the circumference of the annular groove 502. Both ends of the protrusions 504 along the circumference of the annular groove 502 are provided with inclined surfaces 505. The angle between the inclined surfaces 505 and the bottom wall of the annular groove 502 is obtuse, which can facilitate the support plate 503 to move to the top of the protrusion 504 when moving in the annular groove 502.

[0055] The implementation principle of the ball mill for grinding tile raw materials in the embodiment of the present application is as follows: the tile raw materials enter the first grinding chamber 201 from the feed pipe 103, the machine body 101 rotates, driving the large balls 301 and the small balls 302 to grind the raw materials, and after the raw materials are ground into particles, they pass through the second filter screen 203 and enter the second grinding chamber 202, and the small balls 302 further grind the raw material particles. After the small balls 302 grind the raw material particles for a period of time, the machine body 101 stops rotating, the staff removes the plug 105, and the machine body 101 rotates, which can drive the raw material particles to enter the second tube 402 through the long hole 404. While the machine body 101 rotates, it can drive the small balls 302 hits the second tube 402 to lift one end of the second tube 402 connected to the flexible ring 403, so as to facilitate the input of the raw material particles from the second tube 402 into the rotating shaft 102. The raw material particles output by the rotating shaft 102 are sent to the first filter 500. The first filter 500 can filter the raw material particles. The raw material particles of qualified size pass through the first filter 500 and enter the collection bucket 501. The raw material particles of unqualified size remain on the first filter 500. The staff can judge whether the raw material particles are ground to the qualified size based on the raw material particles of unqualified size on the first filter 500, so as to facilitate the observation of the size of the raw material particles.

[0056] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
