Description

Technical Field

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

[0002] Ceramics are made from natural minerals such as clay, quartz, and feldspar. These materials are screened, crushed, and then stirred with water to form a slurry. This slurry is then dehydrated through filter pressing to form a block of clay. To improve its plasticity, the clay is aged for one to two months to evenly distribute the moisture and allow organic matter to ferment and soften the clay. Finally, it is extruded through a vacuum kneading machine to remove air bubbles and create a dense, impurity-free clay.

[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, when using the existing ball mill, the balls are made to fall freely at a medium speed to be crushed, and then the balls are adjusted 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, which makes it impossible to improve the grinding and crushing efficiency by high-speed rotation.

[0039] In order 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 in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection 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 invention for which protection is sought, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0041] Existing ball mills are equipped with multiple balls, which crush and grind materials through the impact of the balls. However, when using existing ball mills, they use medium speed to make the balls fall freely and then crush them, and then adjust to low speed mode for grinding. If the speed is too fast, the centrifugal force causes the balls to rotate inside the cylinder, which makes it impossible to achieve the crushing and grinding effect. As a result, it is impossible to improve the grinding and crushing efficiency by high-speed rotation. Therefore, in order to solve the above problems, this case proposes the following technical solutions:

[0042] See also Figures 1 to 7 The present invention provides a technical solution for preparing a ceramic 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 zirconium oxide, 1-2 parts of rare earth oxide, 2-3 parts of sodium carboxymethyl cellulose, 1-2 parts of polyvinyl alcohol, and 2-5 parts of talc;

[0043] S2. Raw material drying: drying kaolin, quartz sand, feldspar and activated carbon powder;

[0044] S3. Raw material grinding: kaolin, quartz sand, feldspar, and activated carbon powder are ground by a grinding device, which includes a grinding chamber 1. An internal spacer 12 is installed inside the chamber body 11 of the grinding chamber 1. The internal spacer 12 guides the rolling of grinding balls 15 installed in the chamber body 11;

[0045] S4. Raw material mixing: premix activated carbon powder, silver ion modifier, zirconium oxide, and rare earth oxide trace additives uniformly. Second mixing: add the first mixture and kaolin, quartz sand, and feldspar main materials into a mixer, add appropriate amount of water for wet mixing, and mix for ≥30 minutes to ensure uniformity.

[0046] S5. Aging treatment: Aging the mixed clay for 24-48 hours to improve plasticity and reduce cracks.

[0047] S6. Molding: The mixed slurry is injection molded, pressed, or rolled.

[0048] S7. Drying: The formed green body is naturally dried to a moisture content of ≤5%, avoiding direct sunlight. The naturally dried green body is then oven dried at a temperature of 80-100°C for 4-6 hours to ensure uniform evaporation of moisture.

[0049] S8, firing: bisque firing the dried body at a temperature of 800-1000°C for 2-4 hours to increase the body strength, and glaze firing the glazed body at a temperature of 1200-1300°C for 6-8 hours to form a dense glaze surface.

[0050] The structure of the grinding device includes a grinding chamber 1, with shaft frames 2 provided on both sides of the grinding chamber 1 for support, a base frame 3 provided at the bottom of the shaft frame 2, a driver 5 installed on the surface of the base frame 3, and 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 frame 2 through a hollow shaft 14, and the interior of the chamber body 11 is filled with grinding balls 15 of different diameters. When rotating, the grinding balls 15 adhere to the surface of the chamber body 11 under the action of centrifugal force, and then move along the surface of the inner spacer 12. The guidance of the inner spacer 12 can enable the grinding balls 15 to fall more quickly, thereby 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.

[0051] The specific structure of the inner spacer 12 includes side plates 121, which are attached to both sides of the warehouse body 11, and a guide inner plate 122 is set in the middle to guide the steel ball. A first hollow shaft 124 and a second hollow shaft 125 connected to the inner warehouse of the warehouse body 11 are respectively installed on both sides of the side plate 121. In order to prevent the installation angle of the guide inner plate 122 from changing, a buffer 123 is installed at the end of the first hollow shaft 124, which is connected to the shaft frame 2 through the buffer 123. The buffer 123 plays a buffering and fixing role, The impactor 123 includes a connecting ring 231 connected to the first hollow shaft 124 and a positioning plate 233 connected to the shaft frame 2. A sliding rod 234 is fixed on the surface of the positioning plate 233 and the connecting ring 231. A movable hole 232 is also provided at the position opposite to the fixed position of the sliding rod 234. A pull rod 235 is provided between the sliding rods 234 for buffering. The pull rod 235 adopts a spring rod to limit the position between the connecting ring 231 and the positioning plate 233. At the same time, it can also buffer the grinding ball 15 when turning, thereby improving the service life of the equipment.

[0052] The structure of the guide inner plate 122 includes a first baffle 201, which is used to form a shell with the side plate 121, and a second baffle 202 is installed between the third baffle 203 and the first baffle 201, and the second baffle 202 and the first baffle 201 form a guide groove 204, and the guide groove 204 is used to pass the small-diameter grinding balls 15. Specifically, the grinding balls 15 pass through the third baffle 203 and are separated by the third baffle 203. The small-diameter grinding balls 15 are separated by the third baffle 203 and decelerated along the guide groove 204, enter the bottom and form low-speed grinding, while the large-diameter grinding balls 15 can crush the internal materials under the action of gravity.

[0053] The structure of the second baffle 202 includes a first arc plate 21, which is connected to the third baffle 203. A first separation groove 22 is provided on the surface of the first arc plate 21, and a reinforcement 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 balls 15 passing through the guide groove 204, which can avoid the blockage of the guide groove 204 caused by the increase of the grinding balls 15 when the rotation speed is too fast. The reinforcement strip 23 improves the strength of the first separation groove 22 and can also perform a second deceleration on the grinding balls 15.

[0054] In order to fix the first arc plate 21, a limit plate 24 is set between the first arc plate 21 and the third baffle 203, and a buffer rod 25 is set through the limit plate 24. The buffer rod 25 provides support and can buffer the grinding ball 15. The vibration generated when the grinding ball 15 hits the buffer rod 25 can make the first arc plate 21 shake, thereby avoiding sticking during the crushing process, keeping the first arc plate 21 clean, and avoiding affecting the proportion of the next mixing.

[0055] The third baffle 203 is used to guide the path of the grinding balls 15. The third baffle 203 is provided with a first guide plate 31. The first guide plate 31 is used to pour the grinding balls 15. During rotation, due to the action of centrifugal force, the grinding balls 15 pass through the first guide plate 31 and enter the steering plate 32. The steering plate 32 is an arc-shaped structure. After the arc transition, it passes through the second guide plate 34 and falls vertically. A sliding bar 35 is provided on the surface of the second guide plate 34. The sliding bar 35 rotates the grinding balls 15, and the rotation can improve the efficiency of falling and crushing. Since a large number of grinding balls 15 fall vertically through the second guide plate 34, the equipment can only run at high speed to improve efficiency when crushing, and cannot be ground. For this purpose, a second separation groove 33 is provided at the steering plate 32. The grinding balls 15 with small diameters pass through the second separation groove 33, and the grinding balls 15 can be ground after deceleration.

[0056] The improved device processes the grinding balls 15 through the inner spacer 12, and the third baffle 203 separates the grinding balls 15, so that the large-diameter and small-diameter grinding balls 15 move through the surface of the third baffle 203 and the surface of the guide groove 204 respectively. Under high-speed movement, the track formed by the deflection plate 32 of the third baffle 203 and the second guide plate 34 causes the grinding balls 15 to fall quickly, thereby being able to be crushed under high-speed conditions. In the process of high-speed rotation, the second separation groove 33 on the surface of the deflection plate 32 allows the small-diameter grinding balls 15 to enter. The grinding balls 15 are decelerated under the action of the buffer rod 25, and the spatial separation of the limit plate 24 reduces the accumulation of excessive grinding balls 15 to form a blockage. A through first separation groove 22 is set on the surface of the first arc plate 21. The first separation groove 22 is used to further separate the small-diameter grinding balls 15, reduce their movement speed, and get closer to the bottom of the grinding bin 1 during rotation, thereby improving the grinding effect.

[0057] The above only describes the basic principles and preferred embodiments of the present invention. Those skilled in the art may make many changes and improvements based on the above description, and these changes and improvements should fall within the scope of protection of the present invention.

[0058] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
