Description

Technical Field

[0001] The invention discloses a ceramic preparation process for removing chlorine and activating water, belonging to the field of ceramic production equipment. Background Art

[0002] Ceramics uses clay, quartz, and feldspar as raw materials. They need to be screened, crushed, and then mixed with water to form mud. Then, they are dehydrated by filter pressing to form blocky mud. To improve plasticity, the mud needs to be "aged" for 1-2 months to evenly distribute the water and allow organic matter to ferment and soften the clay. Finally, it is squeezed through a vacuum mud kneading machine to expel bubbles and form dense mud without impurities.

[0003] During the processing, the raw materials need to be ground, and the ground materials are convenient for mixing. A ball mill is used for mixing the materials. A plurality of balls are arranged inside the ball mill, and the materials are crushed and ground by the impact of the balls. However, the existing ball mill uses a medium speed to make the balls fall freely and then break them, and then adjusts to a low-speed mode for grinding. Once the speed is too fast, the centrifugal force causes the balls to rotate inside the cylinder, and the crushing and grinding effects cannot be produced, thereby making it impossible to improve the grinding and crushing efficiency by high-speed rotation.

Under high-speed movement, the track formed by the steering plate and the second guide plate of the third baffle causes the grinding balls to fall rapidly, and thus can be broken under high-speed conditions. During the high-speed rotation, the second separation groove on the surface of the steering plate allows the small-diameter grinding balls to enter. The grinding balls are decelerated under the action of the buffer rod, and the spatial separation of the limiting plate reduces the concentration of too many grinding balls together to form a blockage. A through first separation groove is provided on the surface of the first arc plate, and the first separation groove is used for further separation of the small-diameter grinding balls, reducing their movement speed, getting closer to the bottom of the grinding chamber during rotation, and improving the grinding effect.

[0027] To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0028] In the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality" means two or more unless otherwise specifically defined.

[0029] There are multiple rolling balls inside the existing ball mill, and crushing and grinding are carried out through the impact of the rolling balls. However, when the existing ball mill is in use, medium speed is adopted to make the rolling balls fall freely and then break, and then it is adjusted to the low-speed mode for grinding. Once the speed is too fast, the acting force of centrifugal force makes the balls rotate inside the cylinder body, and no crushing and grinding effects can be produced. As a result, the efficiency of grinding and crushing cannot be improved by means of high-speed rotation. Therefore, to solve the above problems, the following technical solutions are proposed in this case: Please refer to Figures 1 to 7 , the present invention provides a technical solution for a ceramic preparation process for removing chlorine and activating water quality: S1. Raw material preparation: 40-50 parts of kaolin, 20-30 parts of quartz sand, 10-15 parts of feldspar, 5-10 parts of activated carbon powder, 1-3 parts of silver ion modifier, 5-7 parts of zirconia, 1-2 parts of rare earth oxide, 2-3 parts of carboxymethyl cellulose sodium, 1-2 parts of polyvinyl alcohol, 2-5 parts of talc powder; S2. Raw material drying: Dry kaolin, quartz sand, feldspar, and activated carbon powder. S3. Raw material grinding: Grind kaolin, quartz sand, feldspar, and activated carbon powder through a grinding device. The grinding device includes a grinding bin 1, and an inner spacer 12 is also installed inside the bin body 11 of the grinding bin 1. The inner spacer 12 guides the rolling of the grinding balls 15 installed in the bin body 11. S4. Raw material mixing: Premix the activated carbon powder, silver ion modifier, zirconia, and rare earth oxide micro-additives evenly. Second mixing: Add the first mixture, kaolin, quartz sand, and feldspar main materials to a mixer, add an appropriate amount of water for wet mixing, and the mixing time is ≥30 minutes to ensure uniformity. S5. Aging treatment: Age the mixed mud for 24-48 hours to improve plasticity and reduce cracks.

[0030] S6. Molding: Inject, press, or roll the mixed slurry into shape.

[0031] S7. Drying: Naturally dry the formed green body until the moisture content ≤5%, avoid direct sunlight, and then oven-dry the naturally dried green body at a temperature of 80-100°C for 4-6 hours to ensure uniform evaporation of moisture.

[0032] S8. Firing: Carry out biscuit firing on the dried green body at a temperature of 800-1000°C for 2-4 hours to improve the strength of the green body. Carry out glaze firing on the glazed green body at a temperature of 1200-1300°C for 6-8 hours to form a dense glaze surface.

[0033] The structure of the grinding device includes a grinding chamber 1, which is supported by shaft brackets 2 on both sides. A chassis 3 is provided at the bottom of the shaft brackets 2, and a driver 5 is installed on the surface of the chassis 3. The driver 5 is connected to the grinding chamber 1 through a transmission belt 4. The driver 5 drives the grinding chamber 1 to perform rolling grinding. The structure of the grinding chamber 1 includes a chamber body 11, an inner spacer 12 is installed inside the chamber body 11. The chamber body 11 is connected to the shaft bracket 2 through a hollow shaft 14. The inside of the chamber body 11 is filled with grinding balls 15 of different diameters. When rotating, the grinding balls 15 fit on the surface of the chamber body 11 under the action of centrifugal force, and then move along the surface of the inner spacer 12. Through the guidance of the inner spacer 12, the grinding balls 15 can fall more quickly, improving the grinding efficiency. A chamber door 13 is provided on the surface of the inner spacer 12, and the grinding balls 15 can be replaced and maintained through the chamber door 13.

[0034] Specifically, the structure of the inner spacer 12 includes side plates 121, which are attached to both sides of the chamber body 11. A guiding inner plate 122 is provided in the middle to guide the steel balls. A first hollow shaft 124 and a second hollow shaft 125 communicating with the inner chamber of the chamber body 11 are respectively installed on both sides of the side plates 121. In order to prevent the installation angle of the guiding inner plate 122 from changing, a buffer 123 is installed at the end of the first hollow shaft 124 and is connected to the shaft bracket 2 through the buffer 123. The buffer 123 plays a role of buffering and fixing. The buffer 123 includes a connecting ring 231 connected to the first hollow shaft 124 and a positioning plate 233 connected to the shaft bracket 2. A sliding rod 234 is fixed on the surfaces of the positioning plate 233 and the connecting ring 231. An activity hole 232 is also provided at the relative position where the sliding rod 234 is fixed. A pull rod 235 is arranged between the sliding rods 234 for buffering. The pull rod 235 is a spring rod, which limits the position between the connecting ring 231 and the positioning plate 233, and can also buffer the grinding balls 15 when turning, improving the service life of the equipment.

[0035] The structure of the guiding inner plate 122 includes a first baffle 201, which is used to form a shell with the side plate 121. A second baffle 202 is installed between a third baffle 203 and the first baffle 201, and the second baffle 202 and the first baffle 201 form a guiding groove 204. The guiding groove 204 is used to pass the grinding balls 15 with a small diameter. Specifically, the grinding balls 15 are separated by the third baffle 203 through the third baffle 203. The grinding balls 15 with a small diameter are separated by the third baffle 203 and decelerate along the guiding groove 204, enter the bottom to form low-speed grinding, while the grinding balls 15 with a large diameter can crush the internal materials under the action of gravity.

[0036] The structure of the second baffle 202 includes a first arc plate 21. The first arc plate 21 is connected to the third baffle 203. A first separation groove 22 is provided on the surface of the first arc plate 21. A reinforcing strip 23 is provided between the first separation grooves 22. The width of the first separation groove 22 is greater than the diameter of the grinding ball 15 passing through the inside of the guide groove 204, which can avoid the blockage inside the guide groove 204 caused by the increase in the number of grinding balls 15 when the rotation speed is too fast. The reinforcing strip 23 improves the strength of the first separation groove 22 and can decelerate the grinding ball 15 for the second time.

[0037] And in order to fix the first arc plate 21, a limiting plate 24 is provided between the first arc plate 21 and the third baffle 203, and a buffer rod 25 is penetrated between the limiting plates 24. The buffer rod 25 provides support and can buffer the grinding ball 15. When the grinding ball 15 impacts the buffer rod 25, the generated vibration can cause the first arc plate 21 to shake, thereby avoiding adhesion during the crushing process, keeping the first arc plate 21 clean, and preventing the impact on the ratio of the next mixing.

[0038] The third baffle 203 is used for guiding the path of the grinding ball 15. The third baffle 203 is provided with a first guide plate 31. The first guide plate 31 is used to pour the grinding ball 15. When rotating, due to the action of centrifugal force, the grinding ball 15 passes through the first guide plate 31 and enters the turning plate 32. The turning plate 32 is an arc-shaped structure. After an arc transition, it vertically falls through the second guide plate 34. And a slide bar 35 is provided on the surface of the second guide plate 34. The slide bar 35 makes the grinding ball 15 rotate. After rotation, the efficiency of falling and crushing can be improved. Since a large number of grinding balls 15 vertically falling through the second guide plate 34 will cause the equipment to only run at high speed during crushing to improve efficiency and cannot perform grinding, a second separation groove 33 is provided at the turning plate 32. The second separation groove 33 allows the grinding balls 15 with a small diameter to pass through. The grinding balls 15 after deceleration can perform grinding.

[0039] The improved device processes the grinding balls 15 through the inner spacer 12, and the third baffle 203 separates the grinding balls 15, enabling the grinding balls 15 with large diameters and small diameters to move through the surface of the third baffle 203 and the surface of the guiding groove 204 respectively. Under high-speed movement, the track formed by the turning plate 32 and the second guiding plate 34 of the third baffle 203 causes the grinding balls 15 to fall rapidly, and thus they can be broken under high-speed conditions. Moreover, during the high-speed rotation process, the second separation groove 33 on the surface of the turning plate 32 allows the grinding balls 15 with small diameters to enter. The grinding balls 15 are decelerated under the action of the buffer rod 25, and the spatial separation by the limiting plate 24 reduces the concentration of excessive grinding balls 15 together to form a blockage. On the surface of the first arc plate 21, a through first separation groove 22 is provided. The first separation groove 22 is used for further separation of the grinding balls 15 with small diameters, reducing their movement speed, getting closer to the bottom of the grinding chamber 1 during the rotation process, and improving the grinding effect.

[0040] The above only describes the basic principles and preferred embodiments of the present invention. Those skilled in the art can make many changes and improvements based on the above description, and these changes and improvements should fall within the protection scope of the present invention.

[0041] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
