Description

Technical Field

[0001] This invention relates to the field of ceramic processing, and more particularly to an apparatus and method for segmented slurry grinding. Background Technology

[0002] In the ceramics industry, the ball milling process accounts for the majority of electricity costs. Therefore, the level of electricity consumption in the ball milling process directly affects the company's electricity costs. In order to control electricity costs as much as possible and produce more slurry at a certain cost to provide materials for subsequent production processes, it is necessary to improve the grinding efficiency of the ball milling process. In addition, the quality of the slurry processed in the ball milling process will affect the quality of the products produced later.

[0003] Specifically, existing ceramic enterprises use intermittent ball mills for one-time grinding or use single continuous ball mills for coarse grinding followed by continuous ball milling for fine grinding. The former uses a fixed ratio of mixed grinding balls, resulting in long grinding times, low grinding efficiency, high electricity costs, and high labor intensity. The latter method improves grinding efficiency, but the grinding efficiency is still not fully utilized, and the processing quality fluctuates. The fineness of the coarse grinding slurry fluctuates due to large fluctuations in the feed rate and the influence of quantitative water addition. The fineness of the fine grinding slurry is difficult to control stably, affecting the quality of the slurry processing, which in turn directly affects the quality of subsequent products.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a segmented mud grinding and processing apparatus and method, which aims to solve the problems of high power consumption cost and unstable mud quality produced by ball milling in the prior art, thereby improving the production efficiency and mud quality of mud grinding and processing.

[0022] This invention provides an apparatus and method for segmented mud grinding and processing, such as... Figures 1 to 7As shown, this application includes a segmented mud grinding and processing apparatus for grinding mud multiple times and grinding it to a specific fineness at different locations to ensure that the final mud meets the requirements. Specifically, the segmented mud grinding and processing apparatus includes a support base 1, a grinding component 2, grinding balls 3, and a slurry inlet and outlet component 4. In this embodiment, two support bases 1 are provided. The bottom of the support base 1 is square-shaped, and a support frame is provided on the top. The grinding component 2 is cylindrical and rotatably mounted between the two support frames. The grinding component 2 is provided with multiple grinding chambers to grind mud of different finenesses. In this embodiment, three grinding chambers and a receiving chamber 24 are provided. The mud raw material enters the first grinding chamber and begins grinding. After being ground to a certain fineness, it enters the second grinding chamber for further grinding. After being ground to a certain fineness in the second grinding chamber, it enters the third grinding chamber. After being ground to the required fineness in the third grinding chamber, it finally enters the receiving chamber 24, from which the grinding component 2 is discharged. Grinding balls 3 are placed inside the grinding chamber. When the grinding assembly 2 rotates, the grinding balls 3 move within the grinding chamber to grind the slurry. To obtain slurry of different fineness from different grinding chambers, the diameters of the grinding balls 3 in each chamber are different. By controlling the fineness of the grinding balls 3 within each chamber, the fineness of the slurry obtained from different grinding chambers is controlled. A slurry inlet / outlet assembly 4 is installed inside the grinding assembly 2 to transport the slurry. The inlet / outlet assembly 4 controls the flow of slurry into the grinding assembly 2 for grinding, or controls the flow of slurry within different grinding chambers, allowing the slurry to undergo multiple grinding processes to achieve the required fineness. Furthermore, the assembly 4 controls the flow of slurry from the grinding chamber to the receiving chamber 24 and from the receiving chamber 24 to the outside, thus discharging the slurry from the grinding assembly 2 for further processing.

[0023] Furthermore, the grinding assembly 2 includes a first grinding chamber 21, a second grinding chamber 22, a third grinding chamber 23, a receiving chamber 24, and several grating plates 25, such as... Figure 4As shown, the first grinding chamber 21, the second grinding chamber 22, the third grinding chamber 23, and the receiving chamber 24 are arranged sequentially along the direction of slurry flow. A grid plate 25 is positioned between these four chambers, dividing the grinding assembly 2 into four independent spaces. This prevents the mixing of slurries of different finenesses in different spaces from affecting the grinding process and ensures the quality of the final output slurry. Therefore, three grid plates 25 are used in this embodiment. Simultaneously, to achieve the required fineness of the ground slurry, improve grinding efficiency, and reduce the wear of the grinding balls 3, the grinding chambers and the receiving chamber 24 have different volumes. Specifically, the volume ratio of the first grinding chamber 21, the second grinding chamber 22, the third grinding chamber 23, and the receiving chamber 24 is 4:3:2:1. This is because a finer slurry requires more grinding space and more grinding balls 3, thus ensuring grinding efficiency. Meanwhile, in order to achieve the best grinding effect, the grinding balls used in different grinding chambers and the fineness of the processed mud are also different. The first grinding chamber 21 performs preliminary processing on the mud raw material, and the fineness of the mud raw material is 30%-40% residue on a 325-mesh sieve. After grinding in the first grinding chamber 21, the fineness of the mud is 10%-15% residue on a 325-mesh sieve. At this time, φ50 and φ60 grinding balls 3 are used in the first grinding chamber 21 for preliminary grinding, with the ratio of φ50 to φ60 being 7:3. The preliminary grinding uses larger grinding balls 3 to grind the mud with larger particle size, so as to give full play to the efficiency of the preliminary grinding. After initial grinding in the first grinding chamber 21, the mud enters the second grinding chamber 22 for a second grinding. After the second grinding in the second grinding chamber 22, the fineness of the mud is 3%-5% residue on a 325-mesh sieve. At this time, φ30 and φ40 grinding balls 3 are used in the second grinding chamber 22 for a second grinding, with the ratio of φ30 to φ40 being 5:5. The use of medium-sized grinding balls 3 for the second grinding of the mud ensures the best grinding efficiency for medium-sized mud particles. After the mud undergoes a second grinding in the second grinding chamber 22, it enters the third grinding chamber 23 for final grinding. After grinding in the third grinding chamber 23, the fineness of the mud becomes 2.1%-2.5% residue on a 325-mesh sieve, thus meeting the fineness requirements for the mud. At the same time, the third grinding chamber 23 uses grinding balls 3 of three specifications: φ15, φ20, and φ25. The ratio of the grinding balls 3 of φ15, φ20, and φ25 is 3:3:4, so as to make full use of the grinding efficiency of the smaller grinding balls 3 and grind the mud to the specified fineness.After the slurry is ground in the third grinding chamber 23, it flows into the receiving chamber 24. The receiving chamber 24 collects the slurry to prevent it from overflowing from the grinding assembly 2 and affecting subsequent slurry processing. At the same time, the receiving chamber 24 controls the slurry discharge speed so that the slurry is discharged from the grinding assembly 2 at a uniform speed for further processing.

[0024] To obtain the optimal ratio of the specifications of each grinding chamber of the grinding assembly 2 and the corresponding grinding balls 3, several sets of experiments were conducted before the formal use of the device in this application for the production of grinding slurry. In the first set, the volume ratio of the first grinding chamber 21, the second grinding chamber 22, the third grinding chamber 23 and the receiving chamber 24 was set to 1:1:1:1. At the same time, all φ60 grinding balls 3 were added to the first grinding chamber 21, φ30 and φ40 grinding balls 3 were added to the second grinding chamber 22, with a ratio of 5:5, and φ15, φ20 and φ25 grinding balls 3 were added to the third grinding chamber 23, with a ratio of 3:3:4. After running for a period of time, the slurry output was 8 tons per hour. In the second experiment, the volume ratio of the first grinding chamber 21, the second grinding chamber 22, the third grinding chamber 23, and the receiving chamber 24 was set to 3:3:2:2. Simultaneously, the specifications of the grinding balls 3 added to the first grinding chamber 21 were changed to φ50 and φ60, with the ratio of grinding balls 3 being 5:5. After a period of grinding, the slurry production became 15 tons per hour. In the third experiment, the ratio of the grinding chambers and the receiving chamber 24 was adjusted again. This time, the volume ratio of the first grinding chamber 21, the second grinding chamber 22, the third grinding chamber 23, and the receiving chamber 24 was adjusted to 4:3:2:1. The slurry production obtained in the third experiment became 17 tons per hour, significantly increasing the slurry production, achieving the highest grinding efficiency, and ensuring that the quality of the obtained slurry was within the standard range and met the quality requirements. Therefore, in this application, the volume ratio of the first grinding chamber 21, the second grinding chamber 22, the third grinding chamber 23, and the receiving chamber 24 is determined to be 4:3:2:1. At the same time, the grinding balls 3 in the first grinding chamber 21 are determined to be φ50 and φ60, each accounting for 50%, and the grinding balls 3 in the first grinding chamber 21 are determined to be φ30 and φ40, each accounting for 50%. The grinding balls 3 in the third grinding chamber 23 are determined to be φ15, φ20, and φ25, with a ratio of 3:3:4.

[0025] To allow the slurry to flow smoothly into or out of the grinding assembly 2, or to flow between the grinding chamber and the receiving chamber 24 within the grinding assembly 2, the grating plate 25 is provided with a connecting hole 251. In this embodiment, a connecting hole 251 is provided at the center of one grating plate 25. The slurry inlet / outlet assembly 4 includes an inlet pipe 41, an outlet pipe 42, and a transmission assembly 43. The inlet pipe 41 is installed on the first grinding chamber 21, the outlet pipe 42 is installed on the receiving chamber 24, and the transmission assembly 43 is installed inside the connecting hole 251. The slurry enters the first grinding chamber 21 through the inlet pipe 41. After grinding in the first grinding chamber 21, it enters the second grinding chamber 22 through the transmission assembly 43. Similarly, after grinding in the second grinding chamber 22, the slurry enters the third grinding chamber 23 through the transmission assembly 43, and after grinding in the third grinding chamber 23, it enters the receiving chamber 24 through the transmission assembly 43. Finally, it is discharged from the receiving chamber 24 through the outlet pipe 42. In addition, the inlet pipe 41 and the outlet pipe 42 are respectively installed in the support base 1. By connecting the inlet pipe 41 and the outlet pipe 42 to the drive assembly, the drive assembly drives the inlet pipe 41 and the outlet pipe 42 to rotate around the rotating shaft 11 of the support base 1, thereby driving the grinding assembly 2 to rotate, so that the grinding balls 3 in the grinding chamber grind the mud in the grinding chamber.

[0026] Specifically, in order to enable the transfer assembly 43 to transfer slurry between the first grinding chamber 21, the second grinding chamber 22, the third grinding chamber 23, and the receiving chamber 24, the transfer assembly 43 includes a plurality of first transfer pipes 431, such as... Figure 6 and Figure 7As shown, the first transmission pipe 431 passes through the connecting hole 251. In this embodiment, one first transmission pipe 431 passes through one connecting hole 251, so three first transmission pipes 431 are provided in this embodiment, which respectively connect the first grinding chamber 21 and the second grinding chamber 22, the second grinding chamber 22 and the third grinding chamber 23, and the third grinding chamber 23 and the receiving chamber 24. Meanwhile, in order to limit the transfer of slurry of a specific fineness between different grinding and receiving chambers 24, rotating chutes 433 are provided at both ends of the first transmission pipe 431. The transmission assembly 43 also includes several second transmission pipes 432, which are rotatably mounted on the rotating chutes 433. The second transmission pipes 432 are connected to the first transmission pipe 431. Therefore, a second transmission pipe 432 is installed at each end of the first transmission pipe 431. Thus, in this embodiment, there are six second transmission pipes 432. The second transmission pipes 432 are funnel-shaped, with a narrower end near the first transmission pipe 431 and a wider end away from the first transmission pipe 431. The end away from the first transmission pipe 431 remains open to allow slurry to enter and exit the second transmission pipe 432. Since the second transmission pipe 432 can rotate around the end of the first transmission pipe 431, when the grinding assembly 2 rotates under the drive of the drive assembly, the second transmission pipe 432 always maintains a downward direction under the action of gravity, that is, the opening direction of the second transmission pipe 432 always remains downward. Specifically, after the slurry grinding process is completed, the slurry first enters the second transmission pipe 432 from the bottom opening at one end of the first transmission pipe 431, then flows into the first transmission pipe 431 connected to the second transmission pipe 432, and finally flows into the second transmission pipe 432 connected to the other end of the first transmission pipe 431, and flows out from the bottom opening of the second transmission pipe 432. Because unprocessed, finer slurry is usually located above the grinding chamber or above the connecting hole 251, while processed, finer slurry is located below the grinding chamber or below the connecting hole 251, the second transmission pipe 432 is always pointed downwards to ensure that the slurry entering the next space is processed, rather than unprocessed slurry above the connecting hole 251. This ensures that the slurry entering the next grinding chamber or receiving chamber 24 meets the requirements, thus ensuring the quality of the processed slurry. At the same time, by ensuring that the second transmission pipe 432 is always pointed downwards, the inflow and outflow of slurry at the bottom of the grinding chamber are increased.

[0027] Furthermore, in order to further filter the slurry transported by the transmission assembly 43 and further prevent unprocessed slurry from flowing into the next grinding chamber or receiving chamber 24, the transmission assembly 43 also includes a number of transmission filters 434. The transmission filters 434 are installed at the end of the second transmission pipe 432 away from the first transmission pipe 431, that is, the transmission filters 434 are installed at the opening of the second transmission pipe 432. Specifically, the specifications of the transmission filters 434 installed on different second transmission pipes 432 are different. For example, the transmission filter 434 installed in the second transmission pipe 432 connecting the first transmission pipe 431 of the first processing and grinding chamber and the second processing and grinding chamber is used to filter slurry with a 325-mesh sieve residue greater than 15%. The transmission filter 434 installed in the second transmission pipe 432 connecting the first transmission pipe 431 of the second processing and grinding chamber and the third processing and grinding chamber is used to filter slurry with a 325-mesh sieve residue greater than 5%. The transmission filter 434 installed in the second transmission pipe 432 connecting the first transmission pipe 431 of the third processing and grinding chamber and the receiving chamber 24 is used to filter slurry with a 325-mesh sieve residue greater than 2.5%.

[0028] When the grinding balls 3 grind the mud in the grinding chamber, as the grinding process progresses, the grinding balls 3 gradually become smaller and are eventually completely ground. This results in a decrease in the number of grinding balls 3 that meet the specifications in the grinding chamber. Therefore, it is necessary to replenish the grinding balls 3 in a timely manner during the grinding process. Thus, the top of the grinding chamber is provided with a ball-adding hole 26. Specifically, the top of the first grinding chamber 21, the second grinding chamber 22, and the third grinding chamber 23 are all provided with ball-adding holes 26. The grinding balls 3 are placed in the grinding chamber through the ball-adding holes 26, and the grinding balls 3 are also replenished in a timely manner through the ball-adding holes 26 to ensure the grinding efficiency and improve the quality of the ground mud. After the grinding balls 3 are added, in order to prevent other impurities from entering the grinding chamber through the ball filling hole 26, and also to prevent mud and grinding balls 3 from leaking out of the ball filling hole 26 when the grinding component 2 is rotating, a chamber cover 27 can be detachably installed on the ball filling hole 26 to prevent the grinding balls 3 and mud from falling out of the ball filling hole 26. Therefore, after the grinding balls 3 are placed, the chamber cover 27 is closed to keep the grinding chamber sealed. After the grinding chamber has been running for a period of time, the rotation of the grinding component 2 is stopped, and then the chamber cover 27 is opened, and grinding balls 3 are added into the grinding chamber through the ball filling hole 26.

[0029] This application also includes a method for segmented mud grinding, the steps of which are as follows: S01. Open the chamber cover 27 and add the grinding balls 3 into the grinding chamber through the ball adding hole 26; S02. Connect the slurry inlet pipe 41 to the raw material supply device and connect the slurry outlet pipe 42 to the mud collection device. S03. Drive the grinding assembly 2 to rotate along the rotating shaft 11. The raw material enters the first grinding chamber 21 from the slurry inlet pipe 41. When the grinding assembly 2 rotates, the grinding balls 3 in the first grinding chamber 21 grind the incoming raw material. S04. After the raw material has reached the required fineness after grinding, it passes through the transmission filter 434 and enters the second transmission pipe 432 and the first transmission pipe 431, and then enters the second grinding chamber 22. It is further ground in the second grinding chamber 22, and then passes through the transmission filter 434 and enters the second transmission pipe 432 and the first transmission pipe 431 again, and then enters the third grinding chamber 23. After further grinding in the third grinding chamber 23, it passes through the transmission component 43 and finally enters the receiving chamber 24. It then flows into the mud collection device from the slurry outlet pipe 42 connected to the receiving chamber 24. During the grinding process, the rotation of the grinding component 2 can be stopped, so that the grinding balls 3 can be added through the ball adding hole 26 to ensure the quality of the ground mud.

[0030] Specifically, the grinding assembly 2 is first installed on the support base 1, then the chamber cover 27 is opened, and grinding balls 3 of a specific size are added to the first grinding chamber 21, the second grinding chamber 22 and the third grinding chamber 23 through the ball adding hole 26 respectively. Then, the slurry inlet pipe 41 is connected to the raw material supply device so that the slurry raw material can enter the first grinding chamber 21 through the slurry inlet pipe 41. At the same time, the slurry outlet pipe 42 is connected to the slurry collection device so that the slurry that has been ground can flow into the slurry collection device through the slurry outlet pipe 42 for further processing of the ground slurry. Then, the grinding assembly 2 is driven to rotate around the rotating shaft 11 by the driving assembly, so that the grinding balls 3 in the first grinding chamber 21 grind the mud inside, thereby making the fineness of the mud in the first grinding chamber 21 smaller and smaller. When the fineness of the mud reaches 10%-15% residue on a 325-mesh sieve, it can enter from the opening of the second transmission pipe 432 located in the first grinding chamber 21, and then flow through the first transmission pipe 431 and the second transmission pipe 432 connected to the other end of the first transmission pipe 431. Finally, it flows from the opening of the second transmission pipe 432 to the second grinding chamber 22, and then the mud is ground and processed in the second grinding chamber 22. When the slurry fineness in the second grinding chamber 22 reaches 3%-5% residue on a 325-mesh sieve, the slurry enters the second transmission pipe 432 through an opening within the second grinding chamber 22. It then flows through the first transmission pipe 431 and the connected second transmission pipe 432, and through the opening of this second transmission pipe 432 to the third grinding chamber 23, where it is further ground. When the slurry fineness in the third grinding chamber 23 reaches 2.1%-2.5% residue on a 325-mesh sieve, the slurry enters the second transmission pipe 432 through an opening within the third grinding chamber 23. It then flows through the first transmission pipe 431 and the connected second transmission pipe 432, and through the opening of this second transmission pipe 432 to the receiving chamber 24. After the receiving chamber 24 has collected the slurry, it finally flows from the receiving chamber 24 through the discharge pipe 42 to the slurry collection device. After the grinding chamber has been running for a period of time, stop the rotation of the grinding component 2, open the chamber cover 27 and add grinding balls 3 into the grinding chamber through the ball adding hole 26, so as to ensure the grinding efficiency and the quality of the slurry obtained after grinding.

[0031] It should be understood that the application of the present invention is not limited to the examples above.

3. The apparatus for segmented mud grinding and processing according to claim 2, characterized in that, The support base is provided with a rotating shaft, and the grinding assembly is rotatably mounted on the rotating shaft.

4. A method for segmented mud grinding, applied to the apparatus for segmented mud grinding as described in claim 3, characterized in that, The method includes the following steps: S01. Add the grinding balls into the grinding chamber; S02. Connect the slurry inlet pipe to the raw material supply device and the slurry outlet pipe to the mud collection device. S03. Drive the grinding assembly to rotate along the shaft, so that the raw material enters the first grinding chamber from the slurry inlet pipe. When the grinding assembly rotates, the grinding balls in the first grinding chamber grind the incoming raw material. S04. After the raw material has reached the predetermined fineness requirement, it passes through the transmission filter screen into the second grinding chamber, where it is ground. Then it passes through the transmission filter screen into the third grinding chamber, where it is ground again. After being ground in the third grinding chamber, it passes through the transmission component and finally enters the receiving chamber. It then flows into the mud collection device through the slurry outlet pipe connected to the receiving chamber. During the grinding process, the grinding component is stopped from rotating, so that grinding balls are added through the ball adding hole midway.
