Description

Technical Field

[0001] This utility model relates to the field of ceramic production equipment technology, specifically to a ceramic slurry mixing device. Background Technology

[0002] Ceramic forming mainly employs plastic forming and casting methods. Therefore, the raw materials can be divided into plastic clay and slip. After the raw materials for ceramic production are weighed and proportioned, they are pulverized and mixed through wet ball milling or wet wheel milling. The ceramic slurry is then stirred in a mixing tank. Existing mixing tanks mainly consist of a frame, a mixing tank mounted on the frame, and a stirring mechanism mounted on the frame. A discharge pipe connected to the interior is located at the bottom of the mixing tank, and a switch valve is installed on the discharge pipe. The stirring mechanism mixes and stirs the ceramic slurry to prepare a slurry that meets the requirements. The existing technology has the following problems:

[0003] Existing ceramic slurry mixing devices only allow the mixing paddle to move within a fixed radius circle. Areas near the inner wall of the device easily become mixing "dead zones," preventing the components in the ceramic slurry from mixing thoroughly. This results in inconsistent quality of the produced ceramic products, affecting yield and performance. Furthermore, existing devices lack the multi-dimensional mixing effect of variable-diameter reciprocating motion, making it difficult to quickly break up the initial unevenness of the slurry using conventional mixing methods, leading to low mixing efficiency. In addition, without the disturbance of high-pressure gas, existing devices gradually deposit sediment at the bottom of the device as mixing time increases. Over time, this sediment will clump and harden, potentially clogging various internal channels such as the discharge pipe and gas guide pipe. Utility Model Content

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1 , Figure 2 As shown, this utility model provides a ceramic slurry mixing device, including a device shell 10. Fixing plates 11 are fixedly connected to the bottom of both the front and rear side walls of the device shell 10. Two symmetrical support legs 12 are fixedly connected to the bottom of each of the front and rear fixing plates 11. An observation window 13 is fixedly connected to the front side of the device shell 10. A central controller 14 is fixedly connected to the top of the front side of the device shell 10. A feed pipe 15 communicating with the interior of the device shell 10 is fixedly connected to the top of the device shell 10. A discharge pipe is fixedly connected to the bottom of the device shell 10. A solenoid valve 16 electrically connected to the central controller 14 is fixedly connected to the outer wall of the discharge pipe. A variable-diameter reciprocating stirring assembly 2 is provided inside and at the top of the device shell 10. A high-pressure anti-settling assembly 3 penetrating into the interior is provided at the bottom of the outer wall of the device shell 10.

[0023] like Figure 1 , Figure 2 As shown, the central controller 14 is electrically connected to the solenoid valve 16, and anti-slip pads are fixedly connected to the bottom of each of the four support legs 12.

[0024] The outer casing 10, serving as the main frame of the entire mixing device, is made of sturdy and corrosion-resistant metal materials such as stainless steel. The bottoms of the four support legs 12 are fixedly connected with anti-slip pads, such as rubber pads with anti-slip textures, effectively preventing slippage during operation. An observation window 13, made of transparent high-strength organic glass, is fixed to the front of the outer casing 10 using sealant, allowing operators to observe the mixing of the ceramic slurry inside the device in real time. The central controller 14, model S7-200SMART, is the core control unit of the entire device. As existing technology, it integrates programmable logic controllers (PLCs) and other control components, enabling precise control of various electrical components. The feed pipe 15 facilitates the smooth flow of ceramic slurry into the device. The solenoid valve 16 is a normally closed solenoid valve, which opens accurately upon receiving an opening signal from the central controller 14, enabling the discharge operation.

[0025] like Figure 3 , Figure 4 As shown, the variable diameter reciprocating stirring assembly 2 includes a support base 20. The bottom of the support base 20 is fixedly connected to the top of the device housing 10. A motor 21 is fixedly connected to the top of the support base 20. A bevel gear 22 is fixedly connected to the output end of the motor 21. A bevel gear 23 is meshed with the bottom of the bevel gear 22. A rotating rod 24 is fixedly connected to the inner wall of the bevel gear 23 and is rotatably connected to the top of the device housing 10. The bottom of the rotating rod 24 penetrates into the interior of the device housing 10 and is fixedly connected to an electric telescopic rod 25.

[0026] like Figure 3 , Figure 4 As shown, a fixed ring 26 is fixedly connected to the bottom of the outer wall of the rotating rod 24. Several ring-shaped stirring connecting rods 27 are rotatably connected to the outer wall of the fixed ring 26. The ends of the several stirring connecting rods 27 away from the fixed ring 26 are rotatably connected to stirring vertical rods 290. The bottom of the electric telescopic rod 25 is fixedly connected to a fixed ring 28. Several ring-shaped stirring connecting rods 29 are rotatably connected to the outer wall of the fixed ring 28. The ends of the several stirring connecting rods 29 away from the fixed ring 28 are rotatably connected to the several stirring vertical rods 290. The central controller 14 is electrically connected to the motor 21 and the electric telescopic rod 25.

[0027] When stirring of raw materials is required, the raw materials are first poured into the outer casing 10 of the device through the feed pipe 15. Then, the central controller 14 starts the motor 21. The motor 21 starts running, and the bevel gear 22 fixedly connected to its output end rotates accordingly. The rotation of bevel gear 22 drives the bevel gear 23 meshing with it to rotate. The rotation of bevel gear 23 drives the rotating rod 24 fixedly connected to the inner wall to rotate along its own axis inside the outer casing 10. When the rotating rod 24 rotates, the fixed ring 26 fixedly connected to the bottom of its outer wall also rotates synchronously. Several ring-shaped array of stirring connecting rods 27, which are rotatably connected to the outer wall of the fixed ring 26 by pins, will also perform circular motion. The other end of these stirring connecting rods 27 is rotatably connected to the stirring vertical rod 290, causing the stirring vertical rod 290 to start to swing around the axis of the rotating rod 24. At the same time, the electric telescopic rod 25 in the center... Under the control of controller 14, the electric telescopic rod 25 performs reciprocating telescopic motion. The fixed ring 28 fixedly connected to the bottom of the electric telescopic rod 25 and several stirring connecting rods 29 rotatably connected to it work together to enable the stirring vertical rod 290 to perform reciprocating motion of expansion and contraction in addition to circumferential oscillation. For example, the electric telescopic rod 25 extends and retracts at a frequency of 30 times per minute, so that the stirring vertical rod 290 continuously changes the relative distance with the rotating rod 24. Through the set variable diameter reciprocating stirring component 2, the ceramic slurry at different positions and depths inside the device shell 10 is stirred in an all-round and thorough manner, ensuring that the components of the slurry are mixed evenly and avoiding local uneven concentration. This ensures that the composition uniformity of the entire ceramic slurry reaches a high level, which is beneficial to the quality stability of subsequent ceramic products. At the same time, the combination of variable diameter and reciprocating motion greatly shortens the overall stirring time and improves production efficiency.

[0028] It should be noted that the extension and retraction of the electric telescopic rod 25 is precisely designed so that the stirring rod 290 will not collide with the inner wall of the device housing 10 when it is extending.

[0029] like Figure 5As shown, the high-pressure anti-sedimentation component 3 includes a booster pump 30, which is fixedly connected to the bottom of the left side wall of the device housing 10. The bottom air outlet of the booster pump 30 is fixedly connected to an air guide pipe 31. The end of the air guide pipe 31 away from the booster pump 30 is fixedly connected to an annular air guide pipe 32, which is fixedly connected to the bottom of the outer wall of the device housing 10. The bottom of the annular air guide pipe 32 is fixedly connected to four rectangularly distributed air guide pipes 33. The ends of the four air guide pipes 33 away from the annular air guide pipe 32 all penetrate into the interior of the device housing 10, and the outer walls of the four air guide pipes 33 are fixedly connected to the device housing 10. The outer walls of the four air guide pipes 33 are all fixedly connected to a one-way valve 34.

[0030] like Figure 5 As shown, the central controller 14 is electrically connected to the booster pump 30 and the four one-way valves 34.

[0031] When it is necessary to perform high-pressure disturbance on the sediment at the bottom of the device housing 10, the central controller 14 starts the booster pump 30 at preset time intervals. The booster pump 30 starts working, drawing in and pressurizing outside air. The pressurized air is then delivered through the air duct 31 connected to the bottom air outlet. The air duct 31 transmits the high-pressure air to the annular air duct 32, which is fixedly connected to the bottom of the outer wall of the device housing 10, so that the high-pressure air is evenly distributed within the annular air duct 32. Four rectangularly distributed air ducts 33 fixedly connected to the bottom of the annular air duct 32 further guide the high-pressure air, ensuring that it is delivered to the interior of the device housing 10. Air enters the interior of the device housing 10, forming a large number of bubbles and causing disturbance in the ceramic slurry. This breaks the static sedimentation state that the slurry might otherwise have. At the same time, the design of the one-way valve 34 ensures that air can only enter the device housing 10 through the air guide pipe 33, while the raw materials inside the device housing 10 will not flow into pipes such as the annular air guide pipe 32. Through the high-pressure anti-sedimentation component 3, the solid particles and other components in the slurry can be kept in a suspended state, effectively preventing them from settling and accumulating at the bottom of the device and ensuring the uniformity of the ceramic slurry throughout the mixing process. This also reduces the risk of blockage in the discharge pipe and other components inside the device related to slurry flow.

[0032] After the ceramic slurry has been stirred for a predetermined time or other set discharge conditions have been met, the central controller 14 sends an opening signal to the solenoid valve 16. Upon receiving the signal, the solenoid valve 16 opens. The solenoid valve 16 is normally closed and opens when energized. At this time, the stirred ceramic slurry inside the device housing 10 is smoothly discharged from the device through the discharge pipe fixedly connected at the bottom under the action of gravity, thus completing the entire stirring and discharge process.

[0033] The working principle of this ceramic slurry mixing device will be explained in detail below.

[0034] like Figure 1-5As shown, when it is necessary to stir the raw materials, the raw materials are first poured into the outer shell 10 of the device through the feed pipe 15. Then, the central controller 14 starts the motor 21. The motor 21 starts to run, and the bevel gear 22 fixedly connected to its output end rotates accordingly. The rotation of the bevel gear 22 drives the bevel gear 23 meshing with it to rotate. The rotation of the bevel gear 23 drives the rotating rod 24 fixedly connected to the inner wall to rotate along its own axis inside the outer shell 10. When the rotating rod 24 rotates, the fixed ring 26 fixedly connected to the bottom of its outer wall also rotates synchronously. Several ring-shaped array of stirring connecting rods 27, which are rotatably connected to the outer wall of the fixed ring 26 by pins, will also perform circular motion. The other end of these stirring connecting rods 27 is rotatably connected to the stirring vertical rod 290, causing the stirring vertical rod 290 to start to swing around the axis of the rotating rod 24. At the same time, the electric telescopic rod 25... Under the control of the central controller 14, the electric telescopic rod 25 performs reciprocating telescopic motion. The fixed ring 28 fixedly connected to the bottom of the electric telescopic rod 25 and several stirring connecting rods 29 rotatably connected to it work together to enable the stirring vertical rod 290 to perform reciprocating motion of expansion and contraction in addition to oscillating in a circular motion. For example, the electric telescopic rod 25 extends and retracts at a frequency of 30 times per minute, so that the stirring vertical rod 290 continuously changes the relative distance with the rotating rod 24. Through the set variable diameter reciprocating stirring component 2, the ceramic slurry at different positions and depths inside the device shell 10 is stirred in an all-round and thorough manner, ensuring that the components of the slurry are mixed evenly and avoiding local uneven concentration. This ensures that the composition uniformity of the entire ceramic slurry reaches a high level, which is beneficial to the quality stability of subsequent ceramic products. At the same time, the combination of variable diameter and reciprocating motion greatly shortens the overall stirring time and improves production efficiency.

[0035] When it is necessary to perform high-pressure disturbance on the sediment at the bottom of the device housing 10, the central controller 14 starts the booster pump 30 at preset time intervals. The booster pump 30 starts working, drawing in and pressurizing outside air. The pressurized air is then delivered through the air duct 31 connected to the bottom air outlet. The air duct 31 transmits the high-pressure air to the annular air duct 32, which is fixedly connected to the bottom of the outer wall of the device housing 10, so that the high-pressure air is evenly distributed within the annular air duct 32. Four rectangularly distributed air ducts 33 fixedly connected to the bottom of the annular air duct 32 further guide the high-pressure air, ensuring that it is delivered to the interior of the device housing 10. Air enters the interior of the device housing 10, forming a large number of bubbles and causing disturbance in the ceramic slurry. This breaks the static sedimentation state that the slurry might otherwise have. At the same time, the design of the one-way valve 34 ensures that air can only enter the device housing 10 through the air guide pipe 33, while the raw materials inside the device housing 10 will not flow into pipes such as the annular air guide pipe 32. Through the high-pressure anti-sedimentation component 3, the solid particles and other components in the slurry can be kept in a suspended state, effectively preventing them from settling and accumulating at the bottom of the device and ensuring the uniformity of the ceramic slurry throughout the mixing process. This also reduces the risk of blockage in the discharge pipe and other components inside the device related to slurry flow.

[0036] After the ceramic slurry has been stirred for a predetermined time or other set discharge conditions have been met, the central controller 14 sends an opening signal to the solenoid valve 16. Upon receiving the signal, the solenoid valve 16 opens. The solenoid valve 16 is normally closed and opens when energized. At this time, the stirred ceramic slurry inside the device housing 10 is smoothly discharged from the device through the discharge pipe fixedly connected at the bottom under the action of gravity, thus completing the entire stirring and discharge process.

[0037] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
