Detailed Description
The technical solution of the present invention is further described below with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, the present invention provides a slurry management method, comprising the steps of:
(1) preparing materials: measuring water and ceramic raw materials;
(2) ball milling: feeding the measured water and the ceramic raw materials into a ball mill for ball milling;
(3) and (3) moisture detection: detecting the moisture of the slurry in the ball mill in real time to obtain the moisture content of the slurry;
(4) when the water content of the slurry reaches a preset value, sending the slurry subjected to ball milling into a finished product slurry pool; and (3) when the water content of the slurry is lower than or higher than the preset value, metering the water or the ceramic raw material again and sending the water or the ceramic raw material into the ball mill, and repeating the steps (2) and (3) until the water content of the slurry meets the preset value, and then sending the slurry subjected to ball milling into a finished product slurry pool.
The slurry management method is suitable for ceramic production, and is suitable for ceramic production adopting spray granulation and ceramic production adopting a slip casting forming method. The ceramic raw materials comprise sewage slurry, green mortar, polishing slag, edging slag, additives and aggregate. The sewage slurry is slurry obtained by dehydrating sewage generated by ceramic tiles, and the sewage sources comprise polishing line sewage, sewage generated by cleaning each workshop, partial equipment cooling water, sewage for cleaning each equipment and ball washing sewage in a ball glaze workshop; the mud is slurry prepared from clay raw materials such as clay, kaolin, washing mud, black mud and the like; the green mortar is a slurry prepared by removing iron from green sand, green sand is produced in the Rongchang area and the Yongchuan area in Chongqing city, is a sand raw material, has high iron content, and can be used as a ceramic raw material after removing iron. The water content of the sewage slurry, the mud slurry and the green mortar meet the production standard, and the additives are agents for improving the fluidity and the suspension property of the slurry, such as sodium cellulose, sodium tripolyphosphate and the like. The invention adopts a static metering mode for metering the ingredients and automatically controls the metering operation.
The slurry management method provided by the invention can be used for detecting the moisture of the slurry in the ball mill in real time, adjusting the raw materials in the ball mill according to the detection result until the moisture of the slurry meets the preset value, realizing the accurate control of the moisture of the slurry, controlling the moisture of the slurry in the ball milling process, and simultaneously obtaining the finished slurry by adopting one-time ball milling, thereby realizing continuous large-scale production. The ball mill adopts a three-section continuous ball mill, which is not only beneficial to realizing continuous large-scale production, but also can ensure that the fineness of the slurry can meet the production requirement.
Specifically, in the step (4), when the water content of the slurry is lower than the preset value, metering water again and sending the water into the ball mill, and repeating the steps (2) and (3) until the water content of the slurry meets the preset value; and (3) when the water content of the slurry is higher than the preset value, metering the ceramic raw material again and sending the ceramic raw material into the ball mill, and repeating the steps (2) and (3) until the water content of the slurry meets the preset value. The preset value is the preset water content of the finished slurry, and the preset value is 40-45% (weight percentage).
Further, in the step (3), after the ceramic raw material enters the ball mill for 10-15s, real-time detection of the water content of the slurry is started, and after the water content of the obtained slurry is stable, the water content of the slurry is compared with a preset value. In the initial stage of ball milling, a plurality of ceramic raw materials are not uniformly mixed, the moisture detection is not accurate enough, when the ceramic raw materials enter the ball mill and are ball-milled for 10-15s, all the raw materials are uniformly mixed basically, and the water content of the slurry obtained by detection has a better reference value. Along with the lapse of ball-milling time, thick liquids homogeneity promotes, and the water content that obtains is stable, and the detection numerical value tends to a definite value promptly, or the detection numerical value is the definite value, and this definite value is the accurate water content of thick liquids in the ball mill. At this time, the detected value is compared with a preset value.
Further, in the step (4), when the water content of the slurry is higher than the preset value, the total amount of the ceramic raw materials to be added is calculated, and the adding amount of each ceramic raw material is calculated according to the total amount of the ceramic raw materials and the preset adding proportion of each ceramic raw material. The raw material formula of the ceramic product is preset in the ceramic production, and the amount of each raw material put into the ball mill is calculated according to the formula. When the water content of the slurry in the ball mill is too large, all raw materials in the formula need to be added to ensure the stability of the slurry formula. And when the water content of the slurry is lower than a preset value, calculating the water amount to be added according to the total weight of all the ceramic raw materials fed into the ball mill, the added water amount and the preset value.
Further, in the step (3), a moisture detector is adopted to detect the moisture content of the slurry, and the moisture detector is arranged at a slurry outlet of the ball mill;

b, projecting the light beam of the external light path to the slurry to be measured, reflecting the light beam by the slurry to be measured, and then putting the reflected light beam into an infrared detector; the light beam of the inner light path is thrown into an infrared detector through a reflector;
and c, converting the received optical signal into an electric signal by the infrared detector, and calculating the water content of the slurry to be detected according to the electric signal.
The moisture detector based on the optical principle is adopted, so that the detection precision is higher. Because the reflectivity of the material to infrared rays is different due to different absorption characteristics and stray characteristics, if the absorption wavelength of water is only used, the factors such as the surface state, the color, the structure and the like of the material can interfere with the water content measurement; therefore, the three-wavelength method is adopted, and the interference of other factors on the moisture measurement can be eliminated. The three-wavelength detection method comprises the steps of dividing light emitted by a light source into light beams with three wavelengths by a modulation disc, projecting the light beams with the three wavelengths to the surface of slurry, projecting the light beams reflected by the slurry to an infrared detector, simultaneously directly projecting the other light beams with the three wavelengths to the infrared detector, and detecting and calculating the energy ratio of the slurry reflected light to the light beams with the three wavelengths which are not reflected by the slurry to obtain the accurate water content of the slurry.
Specifically, the infrared detector converts the received optical signal into an electrical signal, amplifies the electrical signal, forms a voltage digital signal, and calculates the water content of the slurry to be measured.

The radar wave level indicator is installed above the slurry in the finished product slurry tank, the height of the slurry in the finished product slurry tank can be accurately measured by the radar wave level indicator, and the measurement accuracy reaches centimeter. And then, the weight of the slurry is obtained according to the diameter of the finished product slurry tank, and the online display of the weight of the slurry is realized. And judging the difference between the weight of the existing slurry in the finished product slurry tank and the storage upper limit weight according to the weight of the slurry, and after the ball milling is finished, sending the slurry into the finished product slurry tank with the difference to finish the automatic distribution of the slurry.
