Description

Technical Field

[0001] The invention relates to the technical field of clay preparation for Jianzhan, and in particular to a clay preparation method of a highly integrated integrated clay preparation device. Background Art

[0002] Jianzhan is a traditional Chinese ceramic tea set with a long history, dating back to the late Tang Dynasty and the Five Dynasties, especially during the Song Dynasty. Jianzhan is known for its unique black or brown glaze and ever-changing glaze color, and is known as the "black peony among porcelains". The firing process of Jianzhan is complicated, requiring multiple processes such as ore selection, crushing, washing, mixing, aging, clay preparation, clay kneading, throwing, repairing, bisque firing, glazing, kiln loading, and roasting.

[0003] Among them, the embryo soil of Jianzhan usually uses embryo soil (or clay) with a high iron content. These embryo soils have high refractoriness and good plasticity, which are the basis of Jianzhan's unique texture and color. However, factors such as the density, iron content, and air density of the embryo soil directly affect the yield rate of the subsequent biscuit-fired embryos, as well as the finished product rate and fine product rate of Jianzhan. However, traditional clay kneading machine equipment produces poor quality clay, many bubbles, large impurities, and low fineness, which makes the finished product rate of Jianzhan extremely low. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a highly integrated integrated mud kneading equipment to solve the problems mentioned in the above background technology part.

[0005] The present invention is achieved through the following technical solutions:

[0007] The screening mechanism is used to filter impurities with a diameter greater than 2 mm in the embryo soil;

[0008] The ultrafine grinding mechanism includes a grinding cylinder, a cutting impeller, a second motor and a blower, wherein the second motor is used to drive the cutting impeller to rotate, a sieve hole portion is provided at the lower end of the grinding cylinder, the mesh number of the sieve hole portion is greater than 550 meshes, the cutting impeller is arranged at the central position corresponding to the sieve hole portion, a plurality of liquid discharge nozzles for discharging water toward the cutting impeller are provided on the inner periphery of the grinding cylinder, a discharge shell is provided on the outer periphery of the sieve hole portion, the second motor is fixedly arranged below the discharge shell, and the blower is used to blow the embryo soil toward the second discharge port side of the discharge shell;

[0009] The iron content detection mechanism is used to analyze the iron content in the embryo soil;

[0010] The stirring mechanism comprises a first material chamber, a second material chamber and a stirring chamber, wherein the first material chamber is used to store lime soil, and the second material chamber is used to store red soil. When the iron content detection mechanism detects that the iron content of the embryo soil is higher than 12%, the first material chamber is opened and lime soil is added to the stirring chamber; when the iron content detection mechanism detects that the iron content of the embryo soil is lower than 7%, the second material chamber is opened and red soil is added to the stirring chamber;

[0011] The aging chamber is used to place the embryo soil still and allow it to mature;

[0012] The variable speed vacuum mud kneading mechanism comprises a stepless servo motor, a vacuum pump and a mud kneading chamber. The vacuum pump is used to extract air from the mud kneading chamber and form a vacuum environment. The stepless servo motor is provided with a stirring shaft that penetrates into the mud kneading chamber.

[0013] The beneficial effects of the present invention are as follows: after the embryonic soil passes through the highly integrated integrated mud kneading equipment of the present invention, the density of the embryonic soil reaches 99.2%, and the embryonic soil particles are finer. The fracture toughness and heat resistance of Jianzhan are enhanced, the intermolecular stress of the embryonic soil is reduced, and the air density of the embryonic soil is as low as 0.3g / cm3. Using the embryonic soil of the present invention for the subsequent process of Jianzhan can increase the yield rate of the blank embryo from 50% to 82.6%, the yield rate of Jianzhan from 20% to 39%, and the overall fine product rate from 9.8% to 23.2%. It greatly reduces the production cost, increases the output of Jianzhan, and also makes the quality of Jianzhan higher. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] 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. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] Reference Figures 1 to 9 As shown, a highly integrated integrated mud kneading equipment includes a screening mechanism 1, an ultra-fine grinding mechanism 2, an iron content detection mechanism 3, a stirring mechanism 4, an aging chamber 5 and a variable speed vacuum mud kneading mechanism 6 which are connected in sequence according to the process. A transmission belt mechanism is provided between the above mechanisms, and the transmission belt mechanism is used to connect the discharge end and the feed end of the mechanism between the two processes, so that the embryo soil can be automatically transmitted according to the process sequence. The transmission belt mechanism belongs to the prior art and will not be described here.

[0027] The screening mechanism 1 is used to filter impurities with a diameter greater than 2 mm in the embryo soil.

[0028] The ultra-fine grinding mechanism 2 is used to cut and grind the embryo soil, so that the particle size of the embryo soil is cut to less than 30um, so that the density of the subsequent embryo soil can reach 99.2%, and the embryo soil particles are finer.

[0029] The iron content detection mechanism 3 is used to detect the iron content of the embryo soil. The iron content detection mechanism 3 detects the iron content by a balanced coil method. The iron content detection mechanism 3 is the same as the metal detector in the prior art, and will not be described in detail here.

[0030] The stirring mechanism 4 includes a first material chamber, a second material chamber and a stirring chamber. The first material chamber is used to store lime soil, and the second material chamber is used to store red soil. When the iron content detection mechanism 3 detects that the iron content of the embryo soil is higher than 12%, the first material chamber is opened and lime soil is added to the stirring chamber. When the iron content detection mechanism 3 detects that the iron content of the embryo soil is lower than 7%, the second material chamber is opened and red soil is added to the stirring chamber. Then, the newly added lime soil or red soil is stirred with the original embryo soil through the stirring chamber, so that the iron element is evenly distributed in various positions of the embryo soil.

[0031] The aging chamber 5 is used to place the embryo soil still and allow it to mature.

[0032] The variable speed vacuum mud kneading mechanism 6 is used to stir the aged embryo soil, reduce the intermolecular stress of the embryo soil, and reduce the air density of the embryo soil.

[0033] After the embryonic soil passes through the highly integrated integrated mud kneading equipment of the present invention, the density of the embryonic soil reaches 99.2%, and the embryonic soil particles are finer. The fracture toughness and heat resistance of Jianzhan are enhanced, the intermolecular stress of the embryonic soil is reduced, and the air density of the embryonic soil is as low as 0.3g / cm3. Using the embryonic soil of the present invention for the subsequent process of Jianzhan can increase the yield rate of the blank embryo from 50% to 82.6%, the yield rate of Jianzhan from 20% to 39%, and the overall fine product rate from 9.8% to 23.2%. It greatly reduces the production cost, increases the output of Jianzhan, and also makes the quality of Jianzhan higher.

[0034] The screening mechanism 1 includes a feeding funnel 11, a first motor 12, a cylindrical screen 13, a base 14 and a slider 15. The base 14 includes two side plates 141 arranged at intervals. The lower end of the slider 15 is connected to the side plate 141 through a first spring 16. The output shaft of the first motor 12 is connected to a universal shaft 121. The other end of the universal shaft 121 passes through one of the sliders 15 and is connected to the central rotating shaft 133 of the cylindrical screen 13. The other end of the central rotating shaft 133 of the cylindrical screen 13 is rotatably connected to another slider 15, and a plurality of counterweights 131 are provided on the periphery of the cylindrical screen 13. The lower end of the feeding funnel 11 extends from the side to the cylindrical screen 13.

[0035] Therefore, when the first motor 12 drives the cylindrical screen 13 to rotate, the centrifugal force generated by the counterweight block 131 causes the cylindrical screen 13 to synchronously generate a certain amplitude of up and down movement during the rotation, so that the movement trajectory of the mineral soil in the cylindrical screen 13 is a three-dimensional movement of horizontal, vertical and inclined, so that the mineral soil can contact various parts of the cylindrical screen 13, thereby improving the screening efficiency and effect. In addition, since the cylindrical screen 13 generates vertical movement, large particles or other impurities can be prevented from getting stuck in the screen holes of the cylindrical screen 13.

[0036] A pressing cover 142 is disposed at the upper end of the side plate 141 , and the upper end of the slider 15 abuts against the pressing cover 142 via the second spring 17 .

[0037] The counterweight block 131 is fixed to the inner wall of the cylindrical screen 13 , and a plurality of the counterweight blocks 131 are arranged in an array along the length direction of the cylindrical screen 13 .

[0038] Specifically, the cylindrical screen 13 includes a screen surface 132, a central rotating shaft 133, and a plurality of connecting shafts 134 connecting the screen surface 132 and the central rotating shaft 133. The screen surface 132, the central rotating shaft 133, and the connecting shafts 134 can be connected by welding or the like.

[0039] The counterweight 131 can be fixed to the inner wall or outer wall of the cylindrical screen 13 by welding or the like. Preferably, the counterweight 131 is fixed to the inner wall of the cylindrical screen 13, and a plurality of counterweights 131 are arranged in an array along the length direction of the cylindrical screen 13. Thus, during the screening process of the cylindrical screen 13, the mineral soil will change its motion trajectory due to the impact with the counterweight 131, increasing the uncertainty of the mineral soil motion trajectory, thereby improving the screening efficiency and effect.

[0040] In order to make the ore and soil fly farther after hitting the counterweight block 131 , increase the mutual collision between the ore and soil, and increase the uncertainty of the movement trajectory of the ore and soil, a rubber layer 1311 is provided on the periphery of the counterweight block 131 to achieve the above purpose.

[0041] The cylindrical screen 13 is wavy and undulates along its length, which can further increase the uncertainty of the movement trajectory of the ore and soil, thereby improving the screening efficiency and effect.

[0042] The base 14 is provided with a material chute 143 and a first material outlet 144 . The material chute 143 is used to receive materials passing through the cylindrical screen 13 . The material chute 143 has an inclined surface 145 extending toward the first material outlet 144 , thereby preventing materials from accumulating in the material chute 143 .

[0043] The universal joint 121 is a double-section universal joint, so that the first motor 12 can be installed and placed in the horizontal direction. The cylindrical screen 13 is connected to the output shaft of the first motor 12 through the universal joint 121, so that the cylindrical screen 13 can move in the vertical direction.

[0044] The ultrafine grinding mechanism 2 includes a grinding barrel 21, a cutting impeller 22, a second motor 23 and a blower 26. The second motor 23 is used to drive the cutting impeller 22 to rotate. A sieve hole portion 211 is provided at the lower end of the grinding barrel 21. The mesh number of the sieve hole portion 211 is greater than 550 meshes. The cutting impeller 22 is arranged at the central position corresponding to the sieve hole portion 211. A plurality of liquid discharge nozzles 212 for discharging water toward the cutting impeller 22 are provided on the inner periphery of the grinding barrel 21. A discharge shell 24 is provided on the outer periphery of the sieve hole portion 211. The second motor 23 is fixedly arranged below the discharge shell 24. The blower 26 is used to blow the embryo soil toward the second discharge port 244 of the discharge shell 24.

[0045] When in use, the cutting impeller 22 cuts the embryo soil by high-speed rotation, and the liquid nozzle 212 sprays water on the embryo soil synchronously. The participation of water makes the crushing process more uniform and delicate, and can effectively prevent the agglomeration and agglomeration of the embryo soil particles, which can improve the density of the embryo soil. In addition, due to the small particle diameter of the embryo soil, after aging, the air density of the embryo soil can be further reduced, providing high-quality raw materials for subsequent biscuit firing, improving the yield rate of the biscuit, and the finished product rate and fine product rate of the Jianzhan. High-speed crushing combined with uniform speed spraying and washing can control the diameter of the embryo soil particles within the range of 25 to 30 μm, and finally discharge through the second discharge port 244 of the discharge shell 24. Since water is added to the embryo soil during the cutting process, the quality of the embryo soil increases after absorbing the water mist, which easily leads to its accumulation between the crushing cylinder 21 and the discharge shell 24. Therefore, the above problem is solved by disposing a blower 26 , which is used to blow the embryonic soil toward the second discharge port 244 , thereby accelerating the speed at which the embryonic soil is discharged from the discharge shell 24 .

[0046] The liquid outlet nozzle 212 discharges water in the form of a spray, so that the water and the embryo soil are mixed more evenly. And by setting the ratio of the total weight of the water outlet nozzle 212 to the total weight of the embryo soil to 25% to 35%, the embryo soil is in a slightly wet state and is easy to gather together. Then, through the high-speed rotation of the cutting impeller 22, the embryo soil can be crushed more evenly and finely, thereby improving the yield rate of the subsequent biscuit-fired biscuits, as well as the finished product rate and fine product rate of the Jianzhan.

[0047] The discharge shell 24 includes a sealing plate 241 arranged around the sieve hole portion 211, and an upper plate 242 and a lower plate 243 arranged at the upper and lower ends of the sealing plate 241. The sealing plate 241 is provided with a second discharge port 244 for the embryo soil to pass through. After being crushed, the embryo soil passes through the sieve hole portion 211 and is then discharged through the second discharge port 244.

[0048] The cutting impeller 22 is provided with a plurality of cutting blades 221, and the cutting blades 221 include a plurality of cutting edges 2211 from the inside to the outside. Preferably, the cutting edges 2211 and the cutting blades 221 are arranged in a V shape, so that the embryo soil is subjected to a strong shear force at the moment of passing through, thereby accelerating the crushing of the embryo soil.

[0049] The ultra-fine grinding mechanism 2 also includes a feed hopper 25. A plurality of support blocks 213 are arranged in an array on the periphery of the grinding cylinder 21. The feed hopper 25 is sleeved on the outside of the grinding cylinder 21 and abuts against the support blocks 213. The support blocks 213 are provided with a groove 2131 for the feed hopper sleeve to be embedded. Thus, the feed hopper 25 and the grinding cylinder 21 are a structure that can be quickly disassembled. By disassembling the feed hopper 25, it is convenient to clean the part of the embryonic soil adhering to the grinding cylinder 21 and the cutting impeller 22 after the embryonic soil is cut.

[0050] The feed funnel 25 is provided with a constricted portion 251. The function of the constricted portion 251 is to prevent the embryonic soil from hitting the liquid discharge nozzle 212 during the process of pouring the embryonic soil.

[0051] A diverter guard plate 214 is provided on the inner periphery of the crushing cylinder 21, and the diverter guard plate 214 is arranged above the liquid outlet nozzle 212. The diverter guard plate 214 further protects the liquid outlet nozzle 212 to prevent the liquid outlet nozzle 212 from being damaged by impact during the process of pouring embryo soil.

[0052] The ultrafine grinding mechanism 2 also includes a base frame 27, and the grinding cylinder 21 is arranged on the base frame 27. The base frame 27 is fixed with a water tank 28. The grinding cylinder 21 is provided with a liquid pipe 215 on the outer periphery above the sieve hole portion 211. The liquid pipe 215 is connected to the water tank 28 and the liquid outlet nozzle 212 respectively. The water tank 28 is provided with a water pump and other structures for providing power to the liquid outlet nozzle 212. The water tank 28 belongs to the prior art. Through the above arrangement, the overall structure of the ultrafine grinding mechanism 2 is compact and occupies a small space.

[0053] The aging chamber 5 of the present invention constitutes a non-ventilated environment, and the temperature is maintained at 15° C. to 25° C., and the relative humidity is maintained at 70% to 90%, thereby reducing the aging time of the embryo soil. The embryo soil only needs to be left in the aging chamber 5 for 15 to 20 days.

[0054] The variable speed vacuum mud kneading mechanism 6 belongs to the prior art. The variable speed vacuum mud kneading mechanism 6 includes a stepless servo motor, a vacuum pump and a mud kneading chamber. The vacuum pump is used to extract air from the mud kneading chamber and form a vacuum environment. The stepless servo motor is provided with a stirring shaft that penetrates into the mud kneading chamber. The stirring shaft is controlled by the stepless servo motor so that it stirs the embryo soil at different speeds.

[0055] The improvement of the present invention mainly lies in that the variable speed vacuum mud kneading machine also includes a current inverter connected to the stepless servo motor. When the stepless servo motor decelerates, the rotor kinetic energy of the stepless servo motor is converted into electrical energy. The current inverter receives the electrical energy and provides kinetic energy for the next rotor acceleration of the stepless servo motor. The current inverter cooperates with the stepless servo motor, and the speed is quickly increased or decreased through regenerative braking energy to achieve a variable speed effect, driving the stirring shaft to perform variable speed stirring on the aged embryo mud.

[0056] Compared with the voltage-type inverter used in the prior art, the traditional voltage-type inverter can indeed effectively regulate the motor when the frequency increases, but when the frequency decreases, it may not provide sufficient response speed to control the motor. In order to solve this limitation, the present invention introduces a current inverter. When the regenerative braking function of the stepless servo motor is needed, the current inverter can convert the kinetic energy of the stepless servo motor into electrical energy and feed it back to the power supply to form a braking effect, thereby effectively reducing the speed of the stepless servo motor. This energy feedback mechanism allows the speed of the stepless servo motor to change rapidly, achieving more precise speed control, thereby improving the mixing efficiency and mixing effect of the embryo soil, improving the density of the embryo soil and reducing the air density of the embryo soil.

[0057] On the other hand, the present invention provides a method for preparing mud using the integrated mud preparing device as described above, comprising:

[0058] S1, filtering impurities from the crushed porcelain ore soil to form embryo soil;

[0059] S2. Cut the embryo soil into particles smaller than 30um;

[0060] S3, detecting and adjusting the iron content of the embryo soil, adjusting the iron content of the embryo soil to 7% to 12%;

[0062] S5. Stir the embryo soil in a vacuum environment.

[0063] The stirring operation of step S5 comprises the following steps:

[0064] S501, stirring at a constant speed maintained at a value between 27 r / min and 37 r / min, and the duration is 4 min to 6 min; preferably, stirring at a constant speed of 32 r / min

[0065] S502, the stirring speed is accelerated from 10 r / min to 40 r / min, and then decelerated from 40 r / min to 10 r / min, with uniform speed stirring, and the duration is 8 min to 12 min; preferably, the above uniform speed stirring is performed for 2-3 times.

[0066] S503, stirring at a variable speed within the range of 36 r / min to 36 r / min, and the duration is 4 min to 6 min.

[0067] Through steps S501-S503, the compactness of the embryonic soil can be improved and the air density of the embryonic soil can be reduced while reducing the stirring time of the embryonic soil.
