Description

Technical Field

[0001] This invention relates to the field of ceramic raw material processing equipment technology, specifically a multi-stage wet ceramic clay cylinder-type rolling device. Background Technology

[0002] In the ceramic production process, the grinding of raw materials such as porcelain clay and earthenware is the core process that determines the quality of the finished ceramic product. The grinding effect directly affects the plasticity, fineness, and particle bonding of the clay, which in turn determines the forming performance of the body and the strength and density of the finished product after firing.

[0003] Currently, the industry commonly uses traditional open stone mills, shallow trough mills, or single-stage wheel mills for mud grinding operations, which have the following significant drawbacks in actual production: During the grinding process, the moisture in the clay evaporates quickly, making it difficult to control the uniformity of the clay's dryness and wetness. This easily leads to problems such as localized drying and uneven plasticity. At the same time, the raw materials are prone to splashing and falling outwards during the grinding process, causing material loss, and the production process generates serious dust and noise pollution. Secondly, the single-stage grinding structure cannot achieve continuous production, requiring single-batch feeding, grinding, and discharge, resulting in low production efficiency. Furthermore, it cannot achieve multi-stage progressive grinding, making it difficult to fully refine and combine the particles inside the clay. For ceramic clay with high plasticity requirements, repeated grinding is necessary, which is time-consuming and labor-intensive.

[0004] Existing equipment cannot accurately match the grinding process according to the characteristics of different types of ceramic raw materials. The grinding time, grinding pressure and grinding stages required for different clays, porcelain clays and special ceramic blanks vary greatly. Existing equipment cannot flexibly adjust process parameters, has poor adaptability, and is difficult to meet the needs of multi-category ceramic production. The discharge method is also limited, and can only discharge through a fixed discharge port. It cannot take into account the needs of continuous production discharge, manual sampling, small batch unloading and equipment cleaning. The manual operation is also inconvenient.

[0005] To address the aforementioned shortcomings, there is currently no wet ceramic clay compaction device in the technology that can achieve closed-loop multi-stage continuous milling, flexibly adapt to different raw material processes, and accommodate both continuous discharge and manual unloading. Summary of the Invention

[0006] The purpose of this invention is to overcome the above-mentioned defects of the prior art and provide a multi-stage wet ceramic clay cylinder-type rolling device, which solves the problems of large pollution from open structure, uneven wet and dry clay, inability to achieve continuous production from single-stage equipment, inability to accurately adapt to different raw material processes, and single discharge method in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A multi-stage wet ceramic clay cylinder-type rolling device includes at least two cylinders. A support frame is fixedly connected to the bottom of each cylinder, and a support assembly is provided on the top of the support frame. The support assembly consists of pressure-bearing rods on both sides of the cylinder and a horizontally arranged mounting plate. The mounting plate is located above the cylinder. A cylinder cover is detachably connected to the top of each cylinder. A traction rod is fixedly connected to the top of the cylinder cover, and a base is fixedly connected to the top of the cylinder cover. A rolling mechanism is provided on the top of the base. A rolling chamber is opened inside the cylinder, and the working end of the rolling mechanism is located inside the rolling chamber. The cylinder body has a manual unloading port on the front, and a door panel is movably connected to the manual unloading port. The door panel is used to close or open the manual unloading port. The two side walls of the cylinder are respectively fixedly connected to connecting plates; adjacent cylinders are sealed in series through the mating connecting plates; A gate valve is installed between the two connecting plates; The cylinder head is provided with a feed inlet, and a feed cover plate is movably connected to the feed inlet. The feed inlet is used to input the material to be processed into the grinding chamber. All cylinders arranged in series are provided with a discharge collection trough on the front side, and the length of the discharge collection trough matches the total length of all cylinders in series; after the door is opened, it can overlap the top edge of the discharge collection trough to form a guide ramp for manual unloading. The rolling mechanism is used to apply rolling force to the wet ceramic clay in the rolling chamber, so that the material is transported to the adjacent cylinder through the connecting pipe, forming a continuous multi-stage rolling process.

[0008] Furthermore, the rolling mechanism includes a servo motor, a reducer, a driven shaft, and at least one rolling wheel; the servo motor and the reducer are both fixedly connected to the top of the base, the output end of the servo motor is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a transmission wheel, the outer wall of the transmission wheel is driven by a chain, the chain is driven by the input end of the reducer, the output end of the reducer is fixedly connected to the top end of the driven shaft, the bottom end of the driven shaft extends into the interior of the rolling chamber, and the rolling wheel is detachably connected to the outer wall of the driven shaft.

[0009] Furthermore, there are two grinding wheels, which are symmetrically arranged about the vertical center line of the driven shaft. When the grinding wheels rotate with the driven shaft, they make circular motions in the grinding chamber, applying grinding and kneading forces to the wet ceramic clay.

[0010] Furthermore, a number of detachable reinforcing screws are equidistantly distributed in a ring at the connection between the cylinder block and the cylinder head. The reinforcing screws are used to lock and fix the cylinder head to the top of the cylinder block.

[0011] Furthermore, a fixed block is fixedly connected to one side of the manual unloading port of the cylinder, a movable rod is movably connected inside the fixed block, a rotating block is fixedly connected to the outer wall of the movable rod, the rotating block is fixedly connected to the door panel, and the movable rod drives the rotating block to rotate, thereby realizing the opening and closing action of the door panel; a limit plate is movably connected to the outer side of the door panel, and a fixed rod is fixedly connected to the other side of the manual unloading port of the cylinder, and the limit plate and the fixed rod are engaged to lock the position of the door panel after it is closed.

[0012] Furthermore, a sealed bearing is fixedly connected to the inner bottom wall of the cylinder body, and the bottom end of the driven shaft is fixedly connected to the inner ring of the sealed bearing. The sealed bearing is used to support the driven shaft and at the same time prevents the material and moisture in the grinding chamber from entering the bearing.

[0013] Furthermore, the connecting discs on both sides of the cylinder are arranged coaxially, and the connecting discs are used to connect with the connecting discs of adjacent cylinders to realize the series connection of multiple cylinders; the connecting discs of a single-stage cylinder or the end cylinder in series can be connected to an external discharge pipe as a material discharge interface.

[0014] Furthermore, the gate valve is internally equipped with a gate plate that can be moved back and forth in the vertical direction. The displacement stroke of the gate plate is used to adjust the flow cross-sectional area of ​​the connecting plate and regulate the material conveying flow rate and the residence and crushing time of the material in the cylinder.

[0015] Furthermore, the number of cylinders connected in series is set according to the material processing requirements, and all cylinders are arranged in series coaxially along a straight line; the discharge collection trough is fixedly arranged on the front side of all connected cylinders, and the door panel overlaps the top edge of the discharge collection trough after opening, forming a guide channel for manual unloading.

[0016] Furthermore, it also includes a control system, which includes a controller, a parameter input module, a gate valve drive unit, a human-machine interaction unit, and a data storage unit; The controller is electrically connected to the parameter input module, the gate valve drive unit, the human-machine interaction unit, the data storage unit, and the servo motor of the rolling mechanism to realize signal transmission and linkage control. The parameter input module is used to input the processing parameters corresponding to different types of wet ceramic clay. The input process parameters include material type, required rolling time for a single-stage cylinder, preset opening degree of the corresponding gate valve, operating speed of the rolling mechanism, and effective number of stages of series rolling. The data storage unit is used to store the process parameters entered by the parameter input module, and at the same time, it pre-stores multiple sets of preset operating modes for standard ceramic raw materials. Each set of preset operating modes corresponds to a set of standard process parameters for a type of raw material. The human-machine interaction unit is used for operators to select preset operating modes, or manually input and modify process parameters, and at the same time displays the real-time opening degree of the gate valves corresponding to each level of cylinder, the operating status of the rolling mechanism, the cumulative rolling time of the material, and equipment operation fault information. The gate valve drive unit is connected to the gate valves corresponding to each stage of the cylinder in a one-to-one transmission connection. It is used to receive control commands from the controller and drive the gate plate of the gate valve to move to the set opening position. The controller, based on the process parameters corresponding to the selected operating mode, sequentially controls the gate valves of each stage of the cylinder to open to a preset degree according to the material conveying direction. Simultaneously, it synchronously controls the servo motors of the rolling mechanism on the corresponding cylinder to run to a set speed, realizing the time-linked control of multi-stage rolling. The controller changes the material flow speed by adjusting the gate valve opening, thereby controlling the residence time of the material in the single-stage cylinder and matching the rolling process requirements of different materials.

[0017] This invention provides a multi-stage wet ceramic clay cylinder-type compaction device, which has the following beneficial effects: Firstly, this invention adopts a closed cylinder series structure to replace the traditional open grinding disc and shallow trough, forming a fully enclosed multi-stage grinding environment, which effectively reduces the loss of clay moisture, ensures uniform dryness and wetness of the clay, avoids raw material splashing and loss, and significantly reduces dust and noise pollution, meeting the requirements of clean production; the multi-stage progressive rolling can fully refine and combine clay particles, significantly improving the plasticity, fineness and uniformity of the clay, and improving the quality of ceramic products. Secondly, the number of cylinders in this invention can be flexibly adjusted according to production needs to adapt to the grinding needs of different outputs and different raw materials; the connecting plates on both sides of the cylinder can realize the series connection of adjacent cylinders, or connect to the external discharge pipe as the discharge port, and can be flexibly configured with single-stage, multi-stage series, graded discharge and other production modes, with extremely strong versatility and adaptability. This invention, through a gate valve and control system, can precisely control the gate opening, adjust the flow rate and residence time of materials in a single-stage cylinder, and preset process parameters and operating modes for different raw materials. It allows for one-click switching to adapt to the grinding requirements of different types of clay, such as daily-use ceramics, art ceramics, and special ceramics. It boasts a high degree of automation, convenient operation, significantly reduces manual labor intensity, and ensures the quality stability of different batches of products. Furthermore, it accommodates both continuous pipeline discharge and manual unloading modes. During normal continuous production, continuous discharge can be achieved by connecting an external discharge pipeline through the connecting plate of the end cylinder. When sampling, small-batch unloading, or equipment cleaning is required, the door panel on the front of the corresponding cylinder can be opened and overlapped with the discharge collection trough to form a guide ramp, facilitating manual unloading. This highly flexible operation significantly improves the convenience of production operations. The cylinder and grinding wheel of this invention can be made of different materials such as steel plate, stainless steel, cast iron, and stone according to the usage requirements. It retains the excellent grinding effect of traditional stone mill on porcelain clay, while taking into account the wear resistance and durability of different materials. The equipment structure is not easily damaged, the sticky material is easy to clean, and the maintenance cost is far lower than that of traditional stone mills, making it suitable for large-scale ceramic production.

[0023] The present invention discloses a multi-stage wet ceramic clay cylinder-type rolling device. The core structure includes a cylinder 1 that can be flexibly connected in series, a rolling mechanism 13, a connecting pipeline assembly, a manual unloading assembly, and a control system. The number of cylinders connected in series and the process parameters can be flexibly adjusted according to the type of ceramic clay, output, and rolling process requirements to realize continuous multi-stage wet rolling operation. The cylinder body 1 is an integral closed cylinder structure with a grinding chamber inside. The material of the cylinder body 1 can be selected from carbon steel plate, stainless steel, cast iron, or wear-resistant stone according to production needs. The inner wall of the cylinder body is smooth and polished to reduce material adhesion and facilitate cleaning. The bottom of the cylinder body 1 is fixedly connected to the support frame 2 by welding or bolting. The support frame 2 is made of welded steel and is used to lift the cylinder body 1 to a set height to match the installation height of the discharge collection trough 19 and the height of manual operation. The top of the cylinder body 1 is detachably connected to the cylinder cover 3 via a reinforcing screw 5. The contact surface between the cylinder cover 3 and the cylinder body 1 is provided with a high-elasticity wear-resistant sealing rubber ring to achieve top sealing of the grinding chamber, effectively preventing moisture evaporation and noise leakage. A traction rod 4 is welded to the top of the cylinder cover 3, which is used to lift the cylinder cover 3 away from the cylinder body 1 by hoisting equipment during equipment maintenance, facilitating the maintenance and replacement of internal parts. Two sets of bases 12 are fixed to the top of the cylinder cover 3 by bolts, which are used to support the servo motor and reducer of the rolling mechanism 13 respectively. The output end of the servo motor of the rolling mechanism 13 is fixed with a rotating shaft via a flat key. A transmission wheel is fixed on the outer wall of the rotating shaft. The transmission wheel is connected to the input end of the reducer via a chain. The reducer is a hardened gear reducer, which can significantly reduce the speed and increase the output torque to ensure the rolling force. The output end of the reducer is fixedly connected to the top of the driven shaft 1303 via a coupling. The driven shaft 1303 extends vertically downward into the interior of the rolling chamber. The bottom end of the driven shaft 1303 is interference-fitted with the inner ring of the sealed bearing 14 on the inner bottom wall of the cylinder 1. The sealed bearing 14 is a waterproof and dustproof double-sealed deep groove ball bearing, which can effectively prevent mud and water from entering the bearing and ensure the smoothness and stability of the rotation of the driven shaft 1303. Two grinding wheels 1304 are fixed to the outer wall of the driven shaft 1303 by a detachable bolt structure. The two grinding wheels 1304 are symmetrically arranged about the vertical center line of the driven shaft 1303. The outer wall of the grinding wheel 1304 is an arc-shaped structure that matches the curvature of the inner bottom wall of the cylinder 1. The grinding wheel 1304 can be made of stone, cast iron, or stainless steel. Different materials and diameters of grinding wheels 1304 can be replaced according to the characteristics of the clay to meet different grinding needs. During operation, the grinding wheel 1304 moves in a circular motion with the driven shaft 1303. Through its own gravity and rotational torque, it applies squeezing, kneading, and grinding forces to the clay, so that the clay particles are fully refined and combined. The front of the cylinder body 1 has a manual unloading port. A fixing block 6 is welded to one side of the manual unloading port. A through hole is opened in the fixing block 6, and a movable rod 7 is movably sleeved in the through hole. A rotating block 8 is welded to the outer wall of the movable rod 7. The other end of the rotating block 8 is integrally formed with the door panel 9. The door panel 9 can be opened and closed by rotating the movable rod 7. A limit plate 10 is movably connected to the outside of the door panel 9 through a pin. A fixing rod 11 is welded to the other side of the manual unloading port. After the door panel 9 is closed, the rotating limit plate 10 is engaged with the fixing rod 11 to lock the door panel 9 and ensure the sealing of the cylinder body during the grinding process. After the door panel 9 is opened, it can be flipped down and overlapped on the top edge of the discharge collection trough 19 to form a downward inclined guide slope. The mud can slide down the slope into the discharge collection trough 19 to complete the manual unloading. Through holes are provided on the left and right side walls of the cylinder body 1, and a connecting plate 16 is welded to the outer end of the cylinder body 1. Between two adjacent cylinder bodies 1, the connecting plate 16 is connected in series with a sealing gasket and bolts to achieve a sealed connection, so that the grinding chambers of multiple cylinder bodies 1 are connected in sequence to form a multi-stage grinding channel. The gate of the gate valve 17 can move up and down in the vertical direction. By adjusting the opening of the gate, the flow cross-sectional area of ​​the through hole is changed, thereby adjusting the flow speed of the material and controlling the residence and grinding time of the material in a single-stage cylinder body 1. A square feed inlet is provided on the cylinder head 3. The feed inlet is connected to a feed cover plate 18 by a hinge. The feed inlet can be used for manual feeding or can be connected to external feeding equipment such as belt conveyor or screw conveyor to realize the continuous input of the mud to be processed. On the front side of all the cylinders 1 arranged in series, there is a discharge collection trough 19 fixed by a bracket. The discharge collection trough 19 is a U-shaped trough structure, and its length matches the total length of all the cylinders 1 in series. It can support the manual unloading of any cylinder 1 and realize the centralized collection and transfer of materials. The control system uses a PLC controller, and the parameter input module can use a keyboard or barcode scanner. The human-machine interface unit uses a touch screen, the gate valve drive unit uses an electric actuator that matches the gate valve 17, and the data storage unit uses a solid-state drive or memory card. Operators can input process parameters corresponding to different mud materials through the parameter input module and store them in the data storage unit to form a dedicated operating mode. During production, the corresponding operating mode is selected through the touch screen, and the controller can automatically control the gate valves at each level to open to the preset opening degree, while controlling the servo motor of the corresponding rolling mechanism 13 to run to the set speed, realizing fully automated multi-stage continuous rolling operation. At the same time, the controller can collect equipment operating data in real time and display it on the touch screen. In case of failure, it can promptly issue alarm information to ensure the safety and stability of equipment operation.

This embodiment describes a three-stage tandem compaction device for ordinary daily-use ceramic clay, with the following specific settings: In this embodiment, the number of cylinders 1 connected in series is 3, namely, a first-stage cylinder, a second-stage cylinder, and a third-stage cylinder. The three sets of cylinders 1 are arranged in series along a straight line and coaxially. Adjacent cylinders are sealed and connected by a connecting plate 16. The discharge side connecting plate 16 of the third-stage cylinder is connected to an external discharge pipeline, which is connected to the subsequent mud-making process. This embodiment focuses on common daily-use ceramic clay, which is a feldspar-quartz-kaolin system ceramic clay with a raw material moisture content of 22%-24%. The total rolling time required is 15-20 minutes, and the fineness requirement of the clay is ≤0.5% residue when passing through a 250-mesh sieve. The process parameters corresponding to this raw material are entered through the parameter input module of the control system to form the daily-use porcelain clay operation mode. The specific parameters are as follows: the preset opening degree of the first-stage cylinder gate valve is 60%, the rolling time is 8 minutes, and the servo motor speed is 30 r / min; the preset opening degree of the second-stage cylinder gate valve is 80%, the rolling time is 6 minutes, and the servo motor speed is 35 r / min; the preset opening degree of the third-stage cylinder gate valve is 100%, the rolling time is 4 minutes, and the servo motor speed is 40 r / min; the effective rolling level is 3 levels. During production, the operator selects the daily-use porcelain clay operating mode through the human-machine interface unit. The controller automatically controls the gate valves 17 corresponding to the three cylinders to open to the preset opening degree, and at the same time controls the corresponding servo motors to run to the set speed. The clay to be processed is continuously input through the feed port of the first-stage cylinder. After being initially ground by the grinding wheel 1304 of the first-stage cylinder, it enters the second-stage cylinder for secondary fine grinding, and then enters the third-stage cylinder for final homogenization grinding. Finally, it is continuously output through the discharge pipe connected to the discharge side connecting plate 16 of the third-stage cylinder, and directly enters the subsequent clay refining and molding processes. During production, if it is necessary to sample the mud in a single-stage cylinder, the gate valve of the corresponding cylinder can be paused, the door plate 9 can be opened, the door plate 9 can be placed on the discharge collection trough 19, a small amount of mud can be taken out for testing, and normal operation can be resumed after the test is qualified. There is no need to shut down the entire line, and the operation is convenient.

The 6 sets of cylinders 1 are arranged in series along a straight line and coaxially. Adjacent cylinders are sealed and connected by a connecting plate 16. The discharge side connecting plate 16 of the sixth-level cylinder is connected to an external discharge pipeline. At the same time, the discharge side connecting plate 16 of each level cylinder can be connected to a branch discharge pipeline to achieve graded discharge. The high-plasticity art ceramic clay used in this embodiment is a clay with high kaolin content. The raw material moisture content is 25%-27%, and the total rolling time required is 40-60 minutes. It has extremely high requirements for the plasticity and fineness of the clay, requiring the residue to pass through a 325-mesh sieve to be ≤0.2% and the clay plasticity index to be ≥18. The process parameters corresponding to this raw material are entered through the parameter input module of the control system to form a high-plasticity clay operation mode. The specific parameters are as follows: the preset opening of the first-stage cylinder gate valve is 30%, the rolling time is 12 minutes, and the servo motor speed is 20 r / min; the preset opening of the second-stage cylinder gate valve is 35%, the rolling time is 10 minutes, and the servo motor speed is 22 r / min; the preset opening of the third-stage cylinder gate valve is 40%, the rolling time is 8 minutes, and the servo motor speed is 25 r / min; the preset opening of the fourth-stage cylinder gate valve is 50%, the rolling time is 8 minutes, and the servo motor speed is 25 r / min; the preset opening of the fifth-stage cylinder gate valve is 60%, the rolling time is 7 minutes, and the servo motor speed is 28 r / min; the preset opening of the sixth-stage cylinder gate valve is 80%, the rolling time is 5 minutes, and the servo motor speed is 30 r / min; the effective number of rolling stages is 6.

During production, after selecting the high-plasticity clay operating mode, the controller automatically controls the gate valves and servo motors at each level to operate according to preset parameters. The clay undergoes a 6-stage progressive grinding process, resulting in fully refined particles and layered combinations, significantly improving plasticity and fineness. Finally, it is continuously output through the discharge pipe of the sixth-stage cylinder. At the same time, depending on the needs of different products, clay of different grinding degrees can be taken out through the branch discharge pipes connected to the corresponding-level cylinder connecting plate 16, adapting to the molding requirements of different art ceramic products, with extremely high flexibility.

[0026] Example 3: Switchable rolling device for special ceramic blanks This embodiment describes a switchable rolling device for special ceramic blanks, with the following specific settings: In this embodiment, the cylinder 1 is set into 3 groups, namely cylinder 1, cylinder 2 and cylinder 3. A bypass pipeline is provided between adjacent cylinders. The cylinders can be controlled by gate valves to achieve flexible switching between single-stage independent operation, two-stage series operation and three-stage series operation, which can be adapted to the grinding requirements of different special ceramic blanks. The special ceramic blanks targeted in this embodiment include alumina ceramic blanks and zircon ceramic blanks. The raw materials have high hardness and require high milling force. The number of milling grades and the time required for different blanks vary greatly. The process parameters for alumina ceramic blanks and zircon ceramic blanks are entered through the parameter input module of the control system, forming two sets of dedicated operating modes: 1.

In this embodiment, the grinding wheel 1304 is made of high-chromium cast iron, which improves wear resistance and is suitable for the grinding requirements of high-hardness special ceramic raw materials. During production, the corresponding operating mode can be directly selected according to the type of billet to be processed. The controller automatically controls the opening and closing of the corresponding gate valve and switches the corresponding series stage and operating parameters. There is no need to manually adjust the equipment, which greatly improves production efficiency and ensures the grinding quality of special ceramic billets.

The connecting discs 16 on both sides of the cylinder are blocked, and the material is discharged only through the manual unloading port on the front, which is suitable for the mud grinding needs of small-batch laboratory tests and new product development. In this embodiment, the gate valve opening, servo motor speed, and rolling time can be manually adjusted through the human-machine interaction unit of the control system.

[0028] Example 5: Open-type ordinary daily-use ceramic clay three-stage series compaction device This embodiment is an open-type 3-stage tandem rolling device for ordinary daily-use ceramic clay. The overall structure is completely the same as that of Embodiment 1, the only difference being the absence of cylinder head 3 and auxiliary components. It is suitable for production scenarios with good workshop ventilation and where frequent observation of the rolling process is required. The specific settings are as follows: In this embodiment, the number of cylinders 1 connected in series is 3, namely, a first-stage cylinder, a second-stage cylinder, and a third-stage cylinder. The three sets of cylinders 1 are arranged in series along a straight line and coaxially. Adjacent cylinders are sealed and connected by a connecting plate 16. The discharge side connecting plate 16 of the third-stage cylinder is connected to an external discharge pipeline, which is connected to the subsequent mud-making process.

[0029] In this embodiment, the cylinder head 3, traction rod 4, reinforcing screw 5, and feed cover plate 18 are not provided. The top of the cylinder body 1 is an open opening, which is directly used as the feed inlet. The base 12 of the rolling mechanism 13 is directly fixed to the horizontal mounting plate of the support assembly 15 by bolts. The driven shaft 1303 extends vertically downward to the inside of the rolling chamber of the cylinder body 1. The installation position and running trajectory of the rolling wheel 1304 are completely consistent with those in embodiment 1. The remaining structures, including the support frame 2, connecting plate 16, gate valve 17, manual unloading port door 9, discharge collection trough 19, and control system, are all the same as those in embodiment 1.

[0030] The common daily-use ceramic clay used in this embodiment is feldspar-quartz-kaolin system ceramic clay with a raw material moisture content of 20%-22%, a total rolling time of 12-18 minutes, and a clay fineness requirement of ≤0.8% residue when passing through a 250-mesh sieve.

[0031] The process parameters corresponding to this raw material are entered through the parameter input module of the control system to form an open daily-use porcelain clay operation mode. The specific parameters are as follows: the preset opening degree of the first-stage cylinder gate valve is 65%, the rolling time is 7 minutes, and the servo motor speed is 32 r / min; the preset opening degree of the second-stage cylinder gate valve is 85%, the rolling time is 5 minutes, and the servo motor speed is 38 r / min; the preset opening degree of the third-stage cylinder gate valve is 100%, the rolling time is 3 minutes, and the servo motor speed is 42 r / min; the effective rolling level is 3 levels.

[0032] During production, the operator selects the open-type daily-use porcelain clay operating mode through the human-machine interface unit. The controller automatically controls the gate valves 17 corresponding to the three cylinders to open to the preset opening degree, and simultaneously controls the corresponding servo motors to run at the set speed. The clay to be processed is continuously fed in through the open feed port at the top of cylinder 1 without opening the feed cover plate, and can be directly connected to the belt conveyor for continuous feeding. After the clay is initially ground by the grinding wheel 1304 of the first-stage cylinder, it enters the second-stage cylinder for secondary refining and grinding, and then enters the third-stage cylinder for final homogenization and grinding. Finally, it is continuously output through the discharge pipe connected to the discharge side connecting plate 16 of the third-stage cylinder, and directly enters the subsequent clay refining and molding processes.

[0033] During production, operators can directly observe the grinding state of the clay inside the cylinder 1 through the open opening at the top of the cylinder without stopping the machine or disassembling parts. The servo motor speed or gate valve opening can be adjusted at any time according to the clay condition. Water, electrolytes, and other auxiliary materials can also be added directly to the cylinder to adjust the clay properties. If it is necessary to sample the clay from a single-stage cylinder, the gate valve of the corresponding cylinder can be paused, the door plate 9 can be opened, and the door plate 9 can be placed on the discharge collection trough 19 to take out a small amount of clay for testing. After passing the test, normal operation can be resumed without stopping the entire line.

[0034] Compared to Example 1, this embodiment has a simpler structure, reduces equipment manufacturing costs by approximately 15%, and is more convenient for maintenance and repair. The interior of the cylinder or the 1304 grinding wheel can be directly cleaned or replaced without the need for hoisting equipment. It also completely solves the sealing wear problem at the connection between the closed cylinder head and the cylinder body, extending the continuous operating time of the equipment. Due to its open structure, the evaporation rate of the clay moisture is slightly higher than that of a closed structure, making it suitable for production scenarios with slightly lower raw material moisture content and good workshop ventilation, especially suitable for the production needs of small-batch, multi-variety daily-use ceramics.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
