[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] like Figure 1-12 As shown, a ball mill for slurrying of slurry without ball stone grinding comprises:

[0038] The ball mill chamber 1 is rotatably connected with an inner rotating drum 14, and a slurry space is enclosed between the two.

[0039] The crushing mechanism 2 includes crushing protrusions 21 arranged in a circumferential array on the inner drum 14, and filtering holes 141 communicating with the slurry space are opened in a circumferential array on the inner drum 14, and the filtering holes 141 are located between two crushing protrusions 21;

[0040] The filter holes 141 are used to filter long fibers.

[0041] Specifically, a base frame 12 is provided on the ball mill 1, and a motor 15 is provided on the base frame 12. The inner drum 14 is rotatably connected to the ball mill 1, and a transmission belt 151 is sleeved between the motor 15 and the inner drum 14 to drive the inner drum 14 to rotate. A slurry space is clamped between the ball mill 1 and the inner drum 14, and a slurry outlet is fixedly connected to the bottom of the slurry space to discharge the slurry after pulping. A blocking end cover 11 is provided on the ball mill 1. When in use, firstly, blanks and water are added to the inner drum 14 according to the proportion of the finished slurry, and then the motor 15 drives the inner drum 14 to rotate. The blanks will be driven by the crushing protrusions 21 to rotate and lose the restriction after moving with the inner drum 14, so as to hit the crushing protrusions 21 and be crushed. The crushed blanks and water merge to form slurry, and the slurry will pass through the filter holes 141 and enter the slurry space to separate the fibers in the slurry, thereby maintaining the quality of the finished slurry and maintaining the regularity of the tile surface when the slurry is made into the finished product.

[0042] In the above technical solution, the ball mill bin 1 is fixed, and the inner rotating drum 14 that can rotate inside drives the blank to rotate and fall in the inner rotating drum 14, and is crushed by the crushing protrusions 21 to promote the fusion of the crushed blank and water to form a slurry. The slurry will be filtered into the slurry space by the filter holes 141 to filter out the long fibers of the slurry, thereby maintaining the regularity of the tile surface when the slurry is made into a finished product.

[0043] As an embodiment provided by the present invention, baffle plates 10 are arranged in a linear array in the slurry space to separate multiple groups of crushing protrusions 21, and limiting plates 22 extending into the slurry space are arranged on the crushing protrusions 21. An elastic blocking plate 16 is arranged on the inner wall of the ball mill 1, and the limiting plate 22 rotates with the inner drum 14 and approaches the elastic blocking plate 16 to squeeze the slurry along the filter hole 141.

[0044] Specifically, a baffle plate 10 is arranged in a linear array in the slurry space, and a flow hole group 101 is opened on the baffle plate 10. The flow hole group 101 is located at the bottom of the slurry space to drive the slurry at the bottom to circulate with each other, so as to facilitate the discharge of the prepared slurry after the end. In the preparation process, as the inner drum 14 rotates, the two adjacent limiting plates 22 will limit the slurry at the bottom of the slurry space and move with the rotation, so that the slurry can flow back from the filter hole 141 into the inner drum 14 to flush the filter hole 141 and avoid the filter hole 141 from being blocked due to the accumulation of long fibers. At the same time, the slurry keeps flowing from the filter hole 141, which can also make the finished slurry fully pulped and smoother. When the limiting plate 22 gradually approaches the elastic blocking plate 16 with the rotation, the two will squeeze the slurry to increase the pressure and assist the slurry to flow back. Then the limiting plate 22 will push the elastic blocking plate 16 to deform and pass over the elastic blocking plate 16.

[0045] First, the blanks and water are added into the inner drum 14 in the proportion of the finished slurry. Then, the inner drum 14 rotates, and the blanks are driven by the crushing protrusions 21 to rotate and move with the inner drum 14, and then fall without restriction to hit the crushing protrusions 21 and be crushed. The crushed blanks and water merge to form slurry, and the slurry passes through the filter holes 141 and enters the slurry space to separate the fibers in the slurry. The two adjacent limiting plates 22 limit the slurry at the bottom of the slurry space and move with the rotation, so that the slurry flows back from the filter holes 141 into the inner drum 14 to flush the filter holes 141.

[0046] As an embodiment provided by the present invention, barbs 23 are symmetrically arranged in a linear array on the crushing protrusion 21 , and the filter holes 141 squeeze slurry toward the barbs 23 .

[0047] Specifically, the crushing protrusion 21 is symmetrically provided with barbs 23 in a linear array, and the tips of the barbs 23 are inclined toward the inner drum 14. The slurry in the slurry space has a certain viscosity. When the movement is restricted by two adjacent limiting plates 22, the slurry will gradually flow back into the inner drum 14 with the rotation. In the process of backflow, it will flow toward the barbs 23, so that the long fibers are retained on the barbs 23, reducing the long fibers in the bottom slurry, thereby promoting the flow of slurry.

[0048] First, the blanks and water are added into the inner drum 14 in the proportion of the finished slurry. Then, the inner drum 14 rotates, and the blanks are driven by the crushing protrusions 21 to rotate and move with the inner drum 14, and then fall without restriction to hit the crushing protrusions 21 and be crushed. The crushed blanks and water merge to form slurry, and the slurry passes through the filter holes 141 and enters the slurry space to separate the fibers in the slurry. The two adjacent limiting plates 22 limit the slurry at the bottom of the slurry space and move with the rotation, so that the slurry flows back from the filter holes 141 into the inner drum 14 to flush the filter holes 141. In the process of backflow, it flows to the barbs 23, so that the long fibers are retained on the barbs 23, thereby reducing the long fibers in the bottom slurry.

[0049] As an embodiment provided by the present invention, the barb 23 is rotatably connected to the crushing protrusion 21 , and the barb 23 turns over as the slurry is squeezed out of the filtering hole 141 .

[0050] Specifically, the barbs 23 are in a state where the tips are tilted toward the inner drum 14 in the default state. As the inner drum 14 rotates, causing the slurry to flow back from the filter holes 141, the barbs 23 will flip along the crushing protrusions 21, making the barbs 23 perpendicular to the crushing protrusions 21, so that the barbs 23 intercept a larger area, thereby enhancing the retention of long fibers.

[0051] First, the blanks and water are added into the inner drum 14 in the proportion of the finished slurry, and then the inner drum 14 rotates. The blanks will be driven by the crushing protrusions 21 to rotate and move with the inner drum 14, and then fall without restriction to hit the crushing protrusions 21 and be crushed. The crushed blanks and water merge to form slurry, and the slurry will pass through the filter holes 141 and enter the slurry space to separate the fibers in the slurry. The two adjacent limiting plates 22 will limit the slurry at the bottom of the slurry space and move with the rotation, so that the slurry will flow back from the filter holes 141 into the inner drum 14 to flush the filter holes 141. During the backflow process, it will flow to the barbs 23, so that the long fibers will be retained on the barbs 23, reducing the long fibers in the bottom slurry. At the same time, the barbs 23 will flip along the crushing protrusions 21, so that the barbs 23 are perpendicular to the crushing protrusions 21, so that the interception area of ​​the barbs 23 is larger.

[0052] As an embodiment provided by the present invention, a shielding portion 161 and a raised corner 162 are sequentially provided on the elastic blocking plate 16 , and the shielding portion 161 is driven to shield the filter hole 141 on the inner drum 14 .

[0053] Specifically, the shielding portion 161 will fit closely to the inner drum 14 to cover the filter holes 141 on the inner drum 14, thereby cooperating with the elastic blocking plate 16 and the movable limiting plate 22 to extrude the slurry, increase the pressure of the slurry extrusion, and assist in cleaning the long fibers. Folding portions 160 are provided at both ends of the shielding portion 161 and between the raised corners 162 and the elastic blocking plate 16. An elastic pulling portion 1601 is provided on the folding portion 160. The deformation pulling force of the elastic pulling portion 1601 between the shielding portion 161 and the raised corners 162 is greater than the deformation pulling force of the elastic pulling portion 1601 between the shielding portion 161 and the elastic blocking plate 16. When the limiting plate 22 continues to approach the shielding portion 161, it will first push against the raised corners 162, so that the shielding portion 161 first approaches the elastic blocking plate 16 to fold, and then as the limiting plate 22 continues to approach, the raised corners 162 fit closely to the inner wall of the ball mill chamber 1 to complete the folding.

[0054] First, the blank and water are added into the inner drum 14 in the proportion of the finished slurry. Then, the inner drum 14 rotates. The blank will be driven by the crushing protrusion 21 to rotate with the inner drum 14 and lose the restriction to fall down, so as to hit the crushing protrusion 21 and be crushed. The crushed blank and water are fused to form slurry, and the slurry will pass through the filter hole 141 and enter the slurry space to separate the fibers in the slurry. The two adjacent limiting plates 22 will limit the slurry at the bottom of the slurry space and move with the rotation, so that the slurry can be filtered out from the filter hole 141. It flows back into the inner drum 14 to flush the filter holes 141, and the shielding portion 161 will fit the inner drum 14 to shield the filter holes 141 on the inner drum 14, thereby cooperating with the elastic blocking plate 16 and the movable limiting plate 22 to squeeze the slurry to flow back. During the backflow process, it will flow to the barbs 23 to allow the long fibers to be retained on the barbs 23, reducing the long fibers in the bottom slurry. At the same time, the barbs 23 will flip along the crushing protrusions 21, so that the barbs 23 are perpendicular to the crushing protrusions 21, so that the area intercepted by the barbs 23 is larger.

[0055] As an embodiment provided by the present invention, a movable groove 13 is opened on the inner wall of the ball mill 1, a spring 221 is arranged between the limiting plate 22 and the crushing protrusion 21, the barb 23 is slidably connected to the limiting sleeve 222 arranged on the limiting plate 22, and the spring 221 pushes the limiting plate 22 into the movable groove 13 to drive the barb 23 to rotate.

[0056] Specifically, the limiting plate 22 is slidably connected to the crushing protrusion 21 and can only slide vertically along the crushing protrusion 21. A spring 221 is arranged between the limiting plate 22 and the crushing protrusion 21. The barb 23 is slidably connected to the limiting plate 22. When the limiting plate 22 moves, the limiting sleeve 222 drives the barb 23 to rotate to expand the barb 23. When the limiting plate 22 fits the inner wall of the ball mill 1, it does not slide. When the limiting plate 22 enters the movable groove 13, it slides in the vertical direction to slide and drive the barb 23 to rotate.

[0057] First, the blanks and water are added into the inner drum 14 in the proportion of the finished slurry, and then the inner drum 14 rotates, and the blanks are driven by the crushing protrusions 21 to rotate with the inner drum 14 and lose their restrictions and fall down, so as to hit the crushing protrusions 21 and be crushed, and the crushed blanks and water are fused to form slurry, and the slurry passes through the filter holes 141 and enters the slurry space to separate the fibers in the slurry, and the two adjacent limiting plates 22 limit the slurry at the bottom of the slurry space and move with the rotation, so that the slurry flows back from the filter holes 141 into the inner drum 14 to flush the filter holes 141, and The shielding portion 161 will fit the inner drum 14 to shield the filter holes 141 on the inner drum 14, thereby cooperating with the elastic blocking plate 16 and the movable limiting plate 22 to squeeze the slurry to flow back. During the backflow process, it will flow to the barbs 23, so that the long fibers will be retained on the barbs 23, reducing the long fibers in the bottom slurry. At the same time, when the limiting plate 22 moves into the movable groove 13, the spring 221 will push the limiting plate 22 to slide, so that the limiting sleeve 222 slides along the barbs 23 and flips along the crushing protrusion 21, so that the barbs 23 are perpendicular to the crushing protrusion 21, so that the area intercepted by the barbs 23 is larger.

[0058] As an embodiment provided by the present invention, a reciprocating groove group 131 is opened on the inner wall of the ball mill chamber 1, and the limiting plate 22 is driven to move along the reciprocating groove group 131 to drive the barbs 23 to reciprocate.

[0059] Specifically, a reciprocating groove group 131 is opened on the inner wall of the ball mill 1, and the reciprocating groove group 131 is arranged at the bottom of the ball mill 1. When the limiting plate 22 moves along the reciprocating groove group 131, the barb 23 will reciprocate and flip back and forth with the reciprocating movement of the limiting plate 22 to stir the slurry at the bottom of the inner drum 14, thereby stirring the slurry and accelerating the slurry to flow into the slurry space.

[0060] First, the blank and water are added into the inner drum 14 in the proportion of the finished slurry, and then the inner drum 14 rotates, and the blank is driven by the crushing protrusion 21 to rotate with the inner drum 14 and loses the restriction and falls down, so as to hit the crushing protrusion 21 and be crushed, and the crushed blank and water are fused to form slurry, and the slurry passes through the filter hole 141 and enters the slurry space to separate the fibers in the slurry, and the two adjacent limiting plates 22 limit the slurry at the bottom of the slurry space and move with the rotation, so that the slurry flows back from the filter hole 141 into the inner drum 14 to flush the filter hole 141, and the shielding portion 161 fits the inner drum 14 to shield the filter hole on the inner drum 14 141, thereby cooperating with the elastic blocking plate 16 and the movable limiting plate 22 to squeeze the slurry backflow, and in the process of backflow, it will flow to the barbs 23, so that the long fibers are retained on the barbs 23, reducing the long fibers in the bottom slurry. At the same time, when the limiting plate 22 moves into the movable groove 13, the spring 221 will push the limiting plate 22 to slide, so that the limiting sleeve 222 slides along the barbs 23 and flips along the crushing protrusion 21, so that the barbs 23 are perpendicular to the crushing protrusion 21, so that the area intercepted by the barbs 23 is larger, and when the limiting plate 22 moves along the reciprocating groove group 131, the barbs 23 will flip back and forth with the reciprocating movement of the limiting plate 22 to stir the slurry at the bottom of the inner drum 14.

[0061] As an embodiment provided by the present invention, it also includes a fiber cleaning mechanism 3, which includes two coupled cleaning rollers 32, and the inner drum 14 is driven to rotate so that the crushing protrusion 21 passes between the two cleaning rollers 32, thereby cleaning the long fibers retained on the barbs 23;

[0062] The barbs 23 on the crushing protrusion 21 turn over and pass between the two cleaning rollers 32 .

[0063] Specifically, the fiber cleaning mechanism 3 also includes a fixed sleeve 33 extending into the inner drum 14, and a fixed plate 312 is arranged on the fixed sleeve 33. The cleaning roller 32 is rotatably connected to the fixed plate 312. When the crushing protrusion 21 passes in front of the cleaning roller 32, the barbs 23 flip over to facilitate cleaning by the cleaning roller 32, and then the crushing protrusion 21 passes through two rotating cleaning rollers 32 to collect the long fibers retained on the barbs 23, thereby gradually reducing the long fibers in the slurry, enabling continuous operation, avoiding the cleaning step after one addition, and accelerating the production progress.

[0064] Furthermore, the cleaning rollers 32 may be provided in multiple groups to cope with multiple groups of crushing protrusions 21 .

[0065] First, the blanks and water are added into the inner drum 14 in the proportion of the finished slurry, and then the inner drum 14 rotates, and the blanks are driven by the crushing protrusions 21 to rotate and move with the inner drum 14, and then lose the restriction and fall down, so as to hit the crushing protrusions 21 and be crushed, and the crushed blanks and water merge to form slurry, and the slurry passes through the filter holes 141 and enters the slurry space to separate the fibers in the slurry, and the two adjacent limiting plates 22 limit the slurry at the bottom of the slurry space and move with the rotation, so that the slurry flows back from the filter holes 141 into the inner drum 14 to flush the filter holes 141, and the shielding portion 161 fits the inner drum 14 to shield the filter holes 141 on the inner drum 14, thereby cooperating with the elastic blocking plate 16 and the movable limiting plate 22 to squeeze the slurry backflow, and in the process of backflow, it will flow to the reverse The barbs 23 are formed on the inner drum 14 so that the long fibers are retained on the barbs 23, thereby reducing the long fibers in the bottom slurry. At the same time, when the limiting plate 22 moves into the movable groove 13, the spring 221 will push the limiting plate 22 to slide, so that the limiting sleeve 222 slides along the barbs 23 and flips along the crushing protrusion 21, so that the barbs 23 are perpendicular to the crushing protrusion 21, so that the area intercepted by the barbs 23 is larger. When the limiting plate 22 moves along the reciprocating groove group 131, the barbs 23 will flip back and forth with the reciprocating movement of the limiting plate 22 to stir the slurry at the bottom of the inner drum 14. During the operation of the inner drum 14, before the crushing protrusion 21 passes the cleaning roller 32, the barbs 23 flip to facilitate cleaning by the cleaning roller 32, and then the crushing protrusion 21 passes through two rotating cleaning rollers 32 to collect the long fibers retained on the barbs 23.

[0066] As the best embodiment provided by the present invention, the cleaning roller 32 includes a fixed cone 321 and an elastic cleaning sleeve 323 sleeved on the fixed cone 321 , and the fiber cleaning mechanism 3 also includes a cleaning frame 31 , on which a fiber scraping plate 311 is provided that fits the elastic cleaning sleeve 323 .

[0067] Specifically, the elastic cleaning sleeve 323 is composed of an elastic sponge and a wire mesh, which is convenient for being sleeved on the fixed cone 321. The wire mesh is the outer layer of the elastic cleaning sleeve 323, which fits the barbs 23 for cleaning and retaining long fibers. The cleaning frame 31 is arranged on the fixed plate 312, and a coupling wheel 322 is arranged on the fixed cone 321. The two sets of coupling wheels 322 fit and rotate with each other. A transmission shaft 331 is rotatably connected in the fixed sleeve 33, and a reversing bevel gear 332 is rotatably connected on the fixed plate 312. The reversing bevel gear 332 is respectively coupled to the transmission shaft 331 and one of the coupling wheels 322 to transmit power and drive the fixed cone 321 to rotate. A fiber scraping plate 311 that fits the elastic cleaning sleeve 323 is arranged on the cleaning frame 31. After the elastic cleaning sleeve 323 rotates to clean the retained long fibers, it will be scraped by the fiber scraping plate 311 to collect the long fibers.

[0068] First, the blank and water are added into the inner drum 14 in the proportion of the finished slurry, and then the inner drum 14 rotates. The blank will be driven by the crushing protrusion 21 to rotate with the inner drum 14 and lose its restriction and fall down, so as to hit the crushing protrusion 21 and be crushed. The crushed blank and water merge to form slurry, and the slurry will pass through the filter holes 141 and enter the slurry space to separate the fibers in the slurry. The two adjacent limiting plates 22 will limit the slurry at the bottom of the slurry space and move with the rotation, so that the slurry will flow back from the filter holes 141 into the inner drum 14 to flush the filter holes 141, and the shielding portion 161 will fit the inner drum 14 to shield the filter holes 141 on the inner drum 14, thereby cooperating with the elastic blocking plate 16 and the movable limiting plate 22 to squeeze the slurry backflow, and during the backflow process, it will flow to the barbs 23, so that the long fibers will be retained on the barbs 23, reducing The spring 221 pushes the limiting plate 22 to slide, so that the limiting sleeve 222 slides along the barb 23 and flips along the crushing protrusion 21, so that the barb 23 is perpendicular to the crushing protrusion 21, so that the area intercepted by the barb 23 is larger. When the limiting plate 22 moves along the reciprocating groove group 131, the barb 23 will flip back and forth with the reciprocating movement of the limiting plate 22 to stir the slurry at the bottom of the inner drum 14. During the operation of the inner drum 14, when the crushing protrusion 21 passes before the cleaning roller 32, the barb 23 flips to facilitate cleaning by the cleaning roller 32, and then the crushing protrusion 21 passes through two rotating cleaning rollers 32 to collect the long fibers retained on the barb 23. After the elastic cleaning sleeve 323 rotates to clean the retained long fibers, it will be scraped by the fiber scraping plate 311 to collect the long fibers.
