[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1 to 5 As shown, this embodiment provides a building ceramics wetting and powder production system, including two main process steps: dry grinding and fine powder wetting, and wet ball milling and fine powder wetting; wherein: Dry grinding includes a raw material storage and batching device. The raw materials in the raw material storage and batching device are classified as dry or wet. Hard stone raw materials are fed into the vertical crusher 7 for crushing via the feeding belt 6, while clay-type raw materials with high moisture content are directly fed onto the feeding belt 8. The vertical mill 9 or the dry ball mill 19 is selected according to the overall moisture content of the raw materials in the formula. The vertical mill 9 and the dry ball mill 19 are respectively connected to the first powder storage bin 13, which stores dry fine powder. Wet ball milling includes a feeder 20, which is connected to a wet ball mill 21. The wet ball mill 21 is connected to a slurry tank 22. The powder in the slurry tank 22 is processed to obtain dry fine powder and then sent to the second powder storage bin 27 for storage. The fine powder wetting process includes a wetting tower 33, which can fully and evenly wet the dry fine powder. The second powder storage bin 27 sends the dry fine powder into the wetting tower 33 through the second air flow channel 28. The powder in the wetting tower 33 falls from the bottom and is sent to the drum screen 37 through the first powder conveying belt 35. The drum screen 37 sends the powder into the gravity-flow restoring bin 41 through the second powder conveying belt 36. The raw material in the gravity-flow restoring bin 41 is sent out through the powder discharge conveyor belt 43.

[0020] Specifically, in dry grinding, the raw materials in the raw material storage and batching device are fed into the vertical crusher 7 via the feeding belt 6. When the moisture content of the raw materials is greater than 4% but less than 12%, the vertical mill 9 is used to grind the raw materials. When the moisture content of the raw materials is less than 4%, the dry ball mill 19 is used to grind the raw materials. After grinding, the dry fine powder is sent to the first powder storage bin 13 for storage. In wet ball grinding, the feeder 20 feeds the raw materials into the wet ball mill 21. After processing, the raw materials are stored in the second powder storage bin 27. The dry fine powder in the first powder storage bin 13 or the second powder storage bin 27 needs to be processed using a wetting tower 33. The wetting tower 33 can fully wet the dry fine powder and maintain the uniformity of wetting. After being wetted by the wetting tower 33, the powder is screened by the drum screen 37 and then sent to the gravity-flow proofing bin 41. When needed, the powder in the gravity-flow proofing bin 41 is sent out via the powder discharge conveyor belt 43. This invention can determine whether to use a vertical mill or a dry ball mill based on the moisture content in the raw material formula, and wets the dry fine powder through a wetting tower. Compared with the traditional wetting method, the wetting tower can wet the dry fine powder more evenly.

[0021] Further refining the scheme, the raw material storage and batching device includes several raw material bins 1. A conveyor belt 2 is installed at the bottom of each raw material bin 1, and a batching belt 4 is installed below the conveyor belt 2. A suspended belt scale 3 is installed on the batching belt 4, and a high-strength magnetic plate 5 is installed at the end of the batching belt 4. The end of the batching belt 4 closest to the high-strength magnetic plate 5 is connected to the feeding belt 6. Small raw material bins 1 are square, while large raw material bins 1 are cylindrical with a conical bottom and three sides with beveled straight plates. The discharge port side of the bin wall extends straight to the bottom. A conveyor belt is installed at the lower end of the conical opening for discharge, which is then metered by the suspended belt scale 3 to achieve online batching. The suspended belt scale 3 discharges the material to a converging batching belt 4, and a high-strength magnetic plate 5 is installed at the end of the batching belt 4. The high-strength magnetic plate 5 attracts iron-containing materials mixed in with the raw materials, which are then fed into a vertical column crusher 7 for crushing.

[0022] Further refining the scheme, the vertical mill 9 is equipped with a vertical mill dust collector 10 and a fan 11. The vertical mill 9 and the dry ball mill 19 are connected to the first powder storage silo 13 via a first rotary elevator 12. The dry ball mill 19 is connected to the first rotary elevator 12 via a first airflow channel 18. The dry ball mill 19 is connected to a separator 16 via a return conveyor belt 14. The separator 16 is equipped with a ball mill dust collector 15. The separator 16 is connected to the first rotary elevator 12 via a second rotary elevator 17. The dry ball mill 19, in conjunction with the separator 16, performs closed-loop grinding production. The fine powder that passes air separation is fed into the first powder storage silo 13 with a capacity of over 3000 tons.

[0023] Further refining the design, a mud iron and impurity removal device 23 is installed on one side of the slurry tank 22. On the side of the mud iron and impurity removal device 23 away from the slurry tank 22, a mud filter press 24, a dryer 25, and a Raymond mill 26 are sequentially arranged. The Raymond mill 26 is connected to the second powder storage silo 27. Fine powder is obtained through mud filter pressing, drying, and Raymond milling, and then the powder enters the wetting tower 33 for wetting. This method is suitable for wet powder production in humid southern regions, expanding its applicability.

[0024] Further refining the scheme, the first powder storage bin 13 sends the powder into the dry powder removal device 30 via the third rotary elevator 29. The dry powder removal device 30 then sends the powder into the fourth rotary elevator 32 via the third airflow channel 31. The fourth rotary elevator 32 sends the powder into the wetting tower 33. The second airflow channel 28 is connected to the third airflow channel 31. The powder in the first powder storage bin 13 is screened by a combination of a single flat screen and a high flat screen. The single flat screen is equipped with an annular brush to clean fibrous materials, while the high flat screen is responsible for screening the powder to the required fineness. The fine powder after high flat screen screening is lifted into the wetting tower 33 via the third airflow channel 31 and the fourth rotary elevator 32.

[0025] Further refining the scheme, the wetting tower 33 includes a top powder storage bin 38, which is fixedly connected to the surrounding area by four columns 42. A powder feeder 40 is installed at the bottom of the top powder storage bin 38, and a high-frequency vibration powder distribution device 39 is connected to the bottom of the powder feeder 40. The high-frequency vibration powder distribution device 39 is connected to the columns 42. Several wetting spray pipes 44 are set below the high-frequency vibration powder distribution device 39, which can wet the powder in all directions. A discharge cone is set below the wetting spray pipes 44, and the first powder conveying belt 35 is located below the discharge cone. The fine powder after being screened by the high-level flat screen is lifted into the top powder storage bin 38 above the wetting tower 33 through the third air flow channel 31 and the fourth rotary elevator 32. The fine powder in the top powder storage bin 38 is evenly distributed and falls downwards, and is evenly moistened by the wetting spray pipe 44. Then it is conveyed by the first powder conveying belt 35, and the powder is distributed without wind by the high-frequency vibration powder distribution device 39. The powder in the tower falls naturally onto the first powder conveying belt 35 after being moistened by its own weight and the fine water mist.

[0026] Specifically, the design of the wetting spray pipe 44 solves the problem of uniform atomization of fine water mist across the cross section of the wetting tower 33. The improved design of the long and short spray rods and the spray direction of the nozzles on the rods effectively solves the problem of uniform fine water mist. The fixing problem of the wetting spray pipe 44 is solved by installing a fixing bracket on the cylinder wall, and the central hanging ring is no longer needed, making operation more convenient.

[0027] Further refining the design, a water supply device 34 is installed on the outside of the wetting tower 33, and the water supply device 34 is connected to the wetting spray pipe 44. The water supply device 34 uses a hot water boiler, which effectively solves the problem of condensation and mud formation caused by using cold water in the wetting spray pipe 44. At the same time, using warm water reduces the powder resting time and solves the problem of long powder resting time in cold winter weather.

[0028] The scheme is further refined. The powder feeder 40 is connected to the high-frequency vibration powder distribution device 39 via a flexible connection. The bottom of the high-frequency vibration powder distribution device 39 is connected to the wetting spray pipe 44 below via a flexible connection. The powder feeder 40 is installed at the bottom of the top powder storage silo 38 to supply powder to the high-frequency vibration powder distribution device 39 via a flexible connection. The high-frequency vibration powder distribution device 39 and the powder distribution port of the wetting tower 33 also use a flexible connection for powder distribution, thereby ensuring that the fine powder distributed by the high-frequency vibration powder distribution device 39 falls directly into the cylinder without dust generation.

[0029] Specifically, the dry fine powder is first conveyed to the top powder storage bin 38 of the wetting tower 33. A powder feeder 40 is installed at the bottom of the top powder storage bin 38. The powder feeder 40 is connected to a powder supply flexible interface with a square top and a round bottom. The flexible interface is connected to a high-frequency vibration powder distribution device 39. The powder outlet is connected to the powder inlet of the wetting tower 33. Long and short umbrella-shaped wetting spray pipes 44 are installed inside the wetting tower 33. The wetting spray pipes 44 can spray out fine water mist. The bottom cone of the wetting tower 33 collects the wetting powder and guides it onto the first powder conveying belt 35.

[0030] Further refining the design, the bottom surface of the high-frequency vibration powder distribution device 39 has four support plates 46 in contact with it. Each of the four support plates 46 is correspondingly and fixedly connected to one of the four columns 42. A bracket is fixedly connected to the bottom of each support plate 46, and the bracket is also fixedly connected to the column 42. The support plates 46 provide support for the high-frequency vibration powder distribution device 39, ensuring stability during operation.

[0031] Further refining the design, each column 42 is equipped with a movable rod 45, which is detachably connected to the column 42. A flange is fixedly connected to the bottom of the movable rod 45, and the flange is detachably connected to the support plate 46 via bolts. The movable rod 45 facilitates the inspection and replacement of parts of the high-frequency vibration powder distribution device 39. The high-frequency vibration powder distribution device 39 is supported by the support plate 46, which is fixed to four columns 42. One of the columns 42 is equipped with the movable rod 45, which can be disassembled, thus facilitating the installation and maintenance of the powder distributor.

[0032] Working principle: Online automatic batching is achieved by combining a separate conveyor belt 2 with a suspended weighing scale. A high-strength magnetic plate 5 is installed on the batching belt 4 to attract iron particles mixed in the raw materials. The raw materials are then fed into a vertical column crusher 7 for crushing. For materials with a total moisture content exceeding 4% but less than 12%, a vertical mill 9 is used for grinding, equipped with a vertical mill dust collector 10 and a fan 11 for dust collection. For materials with a total moisture content less than 4%, a dry ball mill 19 is used for grinding, equipped with a separator 16 for air classification, forming a closed-loop grinding production process. Qualified fine powder enters a first powder storage silo 13 with a capacity of 3000 tons or more. The fine powder in the first powder storage silo 13 is then screened by a single flat screen to remove fibrous materials, and then further processed by a high-strength magnetic separator. The fine powder sieved by the flat screen system is lifted to the top powder storage bin 38 of the wetting tower 33 for later use. The top powder storage bin 38 is connected to the powder feeder 40 to feed powder into the cylinder of the wetting tower 33. The powder is evenly distributed to the high-frequency vibrating powder distribution device 39 through a flexible connection. At the same time, considering the humid areas in the south, the traditional wet powder making is changed to wet powder making. After being ground by the feeder 20 and the wet ball mill 21, the powder is then removed by the mud iron and impurity removal device 23. Then it passes through the filter press, dryer 25 and Raymond mill 26, and is then turned into fine powder. Then it enters the wetting tower 33 for wet powder making, which can also achieve energy saving, emission reduction and environmental protection effects.

[0033] This invention completely solves the problems of selecting grinding methods and equipment for raw materials with different water content in the powder making process of building ceramics; it solves the process path problem of upgrading the existing wet powder making technology to wet powder making; it reforms the existing wet powder making wetting tower with air-driven powder distribution to high-frequency vibration without air-driven powder distribution; and it improves the existing single long and thin water mist bar spraying method in the wetting tower to a long and short alternating spray bar method, so that the fine water mist in the cross-section of the wetting tower is more uniform, thereby simplifying the structure of the wetting tower and improving the production effect.

[0034] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0035] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Various modifications and improvements made by those skilled in the art to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
