Description

Technical Field

[0001] This utility model relates to the field of ceramic production technology, and in particular to a continuous stirring and mixing equipment for ceramic raw materials. Background Technology

[0002] Ceramics are inorganic non-metallic materials made from powdered raw materials such as clay, quartz, and feldspar through molding and sintering. They have characteristics such as high hardness and high temperature resistance and are widely used. The mixing process in their production is crucial. It can eliminate uneven distribution caused by differences in the particle size and density of raw materials and ensure the consistency of the green body composition. By adding substances, the colloidal structure can be optimized to enhance plasticity. It can also promote the sintering reaction, reduce the temperature and shorten the time, and ensure that the ceramics achieve the ideal strength and density.

[0003] However, traditional ceramic raw material mixing equipment mostly adopts single-tank intermittent operation, requiring shutdown for loading and unloading each batch, resulting in low production efficiency. On the other hand, continuous production by connecting multiple mixing devices in series leads to problems such as high energy consumption and complex maintenance. Therefore, we propose a continuous mixing equipment for ceramic raw materials to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing ceramic raw material mixing equipment, such as low production efficiency in traditional single-tank intermittent operation, and high energy consumption and complex maintenance caused by continuous production through the series connection of multiple stirring devices. Therefore, this invention proposes a continuous stirring and mixing equipment for ceramic raw materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A continuous mixing device for ceramic raw materials includes a support frame, a mixing tank rotatably connected inside the support frame, and a partition fixedly connected to the inner wall of the mixing tank, which divides the interior of the mixing tank into a first mixing chamber and a second mixing chamber.

[0007] A sealing cover is fixedly installed on the top of the mixing tank, and two feed ports are opened on the sealing cover, which are respectively connected to the first mixing chamber and the second mixing chamber;

[0008] A fixed feed pipe is fixedly installed on the support frame above the mixing tank, and the fixed feed pipe is connected to the corresponding mixing chamber;

[0009] The top of the sealing cover is provided with a stirring assembly, which includes two stirring rods rotatably mounted on the sealing cover, with the bottoms of the two stirring rods extending into the interior of the first mixing chamber and the second mixing chamber, respectively.

[0010] The support frame is provided with a drive assembly for driving the mixing tank to rotate. The drive assembly includes a drive gear that is rotatably mounted on the support frame via a rotating shaft and a gear ring that is fixedly embedded in the outer wall of the mixing tank. The drive gear meshes with the gear ring for transmission.

[0011] The bottom of the support frame is fixedly connected to a Y-shaped tee pipe, and a conveying pipe is fixedly installed inside the support frame below the mixing tank. The outlet pipe of the tee pipe is rotatably connected to the inside of the conveying pipe.

[0012] In one possible design, the stirring assembly further includes a three-axis gearbox fixedly mounted on top of the sealing cover, with the tops of both stirring rods extending above the sealing cover;

[0013] The two output ends of the three-axis gearbox and the top of the two stirring rods are all fixedly fitted with bevel gears, and the bevel gears on the two stirring rods are meshed with the bevel gears corresponding to the two output ends of the three-axis gearbox; a third motor for driving the three-axis gearbox is fixedly installed on the top of the sealing cover.

[0014] In one possible design, the drive assembly further includes a first motor fixedly mounted on a support frame, the output end of the first motor being fixedly connected to the shaft of the drive gear.

[0015] In one possible design, multiple balls are rolled and embedded inside the support frame, and an annular groove corresponding to the multiple balls is opened at the bottom of the mixing tank. The multiple balls extend into the interior of the annular groove and roll into contact with the top inner wall of the annular groove.

[0016] In one possible design, a limiting ring is fixedly fitted on the outer wall of the mixing tank, and a limiting groove corresponding to the limiting ring is opened on the support frame. The limiting ring extends into the limiting groove and slides in connection with the inner wall of the limiting groove.

[0017] In one possible design, a spiral conveying rod is rotatably mounted inside the conveying pipe, and a second motor that drives the spiral conveying rod to rotate is fixedly mounted at one end of the conveying pipe.

[0018] In one possible design, electric valves are fixedly installed on both inlet pipes of the tee.

[0019] In this application, firstly, the first motor drives the drive gear to mesh with the gear ring, causing the mixing tank to rotate, so that the feed port of the first mixing chamber is aligned with the fixed feed pipe. At this time, the ball rolls in the annular groove to reduce frictional resistance. Meanwhile, the limiting ring slides along the limiting groove to ensure that the mixing tank can rotate smoothly. After the raw material is injected into the first mixing chamber through the fixed feed pipe, the third motor starts and drives the two stirring rods to rotate synchronously through the three-axis gearbox, thereby stirring and mixing the raw material in the first mixing chamber.

[0020] Next, the first motor starts again, driving the mixing tank to rotate, so that the feed inlet of the second mixing chamber is aligned with the fixed feed pipe, and then the raw material is injected into the second mixing chamber. The stirring rod inside stirs the raw material under the drive of the three-axis gearbox.

[0021] After the raw materials in the first or second mixing chamber are mixed, the corresponding electric valve on the three-way pipe is opened, and the material falls into the conveying pipe through the three-way pipe. The screw conveyor pushes the material outward to complete the discharge.

[0022] After the material is discharged, the first motor drives the drive gear to mesh with the gear ring, causing the mixing tank to rotate. This aligns the inlet of the first or second mixing chamber with the fixed feed pipe for further feeding and mixing. If the other mixing chamber has finished mixing, the corresponding electric valve is opened to discharge the material. This cycle is repeated to complete the continuous mixing operation without stopping the machine. During the rotation of the mixing tank, the stirring rod remains stationary with the sealing cover, and only the mixing tank rotates, avoiding the risk of leakage caused by the dynamic sealing structure.

[0023] Beneficial effects: In this utility model, the continuous mixing equipment for ceramic raw materials can switch the working position of the two chambers by rotating the mixing tank. When the first mixing chamber is in the mixing state, the second mixing chamber simultaneously performs feeding or discharging operations, realizing continuous production without intervals, improving the effective working time of the equipment, increasing production capacity, and eliminating the need for pipeline valve switching, thus completely avoiding the risk of blockage.

[0024] In this utility model, the continuous mixing equipment for ceramic raw materials forms a closed discharge channel through a three-way pipe and a spiral conveyor rod. The rotating spiral blades scrape the pipe wall to reduce material residue and avoid cross-contamination when switching between different formula raw materials.

[0025] In this utility model, the continuous stirring and mixing equipment for ceramic raw materials achieves radial positioning of the mixing tank by the cooperation of ball bearings and an annular groove, and the limiting ring restricts axial displacement, ensuring a smooth rotation process, extending the service life of the equipment, and reducing production costs.

[0026] In this invention, the mixing tank is rotated to switch between dual-chamber working states, enabling continuous production without interruption and improving equipment operating time and capacity. A closed discharge channel is formed by a three-way pipe and a spiral conveyor rod, and the spiral blades scrape the pipe wall to reduce material residue and avoid cross-contamination during formula switching. At the same time, the ball bearings, annular groove, and limit ring work together to accurately position the mixing tank, ensuring stable rotation, extending the service life of the equipment, and effectively reducing production costs.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] In one embodiment: Refer to Figure 1-5 A mixing device includes a support frame 1, which serves as a basic support structure. A mixing tank 2 is rotatably connected inside the support frame 1. A partition 3 is fixedly connected to the inner wall of the mixing tank 2, dividing the interior of the mixing tank 2 into a first mixing chamber 201 and a second mixing chamber 202. A sealing cover 4 is bolted to the top of the mixing tank 2. The sealing cover 4 has two inlets 401, which communicate with the first mixing chamber 201 and the second mixing chamber 202 respectively. A fixed feed pipe 5 is fixedly installed above the mixing tank 2 on the support frame 1. The fixed feed pipe 5 is connected to the two inlets 401 via pipe joints, for conveying ceramic raw materials into the chambers.

[0035] A stirring assembly is installed on the top of the sealing cover 4. The stirring assembly includes two stirring rods 6, which are rotatably mounted on the sealing cover 4 via bearings, with their bottom ends extending into the first mixing chamber 201 and the second mixing chamber 202, respectively. A three-axis gearbox 7 is fixed to the top of the sealing cover 4. The top ends of the two stirring rods 6 extend above the sealing cover 4 and are fixedly fitted with bevel gears 8. Bevel gears 8 are also fixed to the two output ends of the three-axis gearbox 7, and the two sets of bevel gears 8 mesh with each other. A third motor 19 is also fixed to the top of the sealing cover 4. The output shaft of the third motor 19 is connected to the input shaft of the three-axis gearbox 7. During operation, the third motor 19 drives the three-axis gearbox 7, which in turn drives the two stirring rods 6 to rotate synchronously through the bevel gears 8, thus stirring and mixing the raw materials in the chambers.

[0036] A drive assembly for rotating the mixing tank 2 is mounted on the support frame 1. The drive assembly includes a first motor 11, a drive gear 10, and a gear ring 9. The first motor 11 is fixedly mounted on the support frame 1, and its output shaft is fixedly connected to the drive gear 10 via a rotating shaft. The gear ring 9 is fixedly embedded in the outer wall of the mixing tank 2, and the drive gear 10 meshes with the gear ring 9 for transmission. Multiple balls 18 are rolled and embedded inside the support frame 1. An annular groove 203 is opened at the bottom of the mixing tank 2, and the balls 18 are embedded in the annular groove 203 and roll in contact with the inner wall of the groove top. At the same time, a limiting ring 17 is fixedly sleeved on the outer wall of the mixing tank 2, and a corresponding limiting groove 101 is opened on the support frame 1. The limiting ring 17 is embedded in the limiting groove 101 and slides in cooperation with the groove wall. When the first motor 11 starts, the drive gear 10 drives the gear ring 9 to rotate the mixing tank 2. The ball 18 rolls in the annular groove 203 to reduce friction. The limiting ring 17 cooperates with the limiting groove 101 to constrain the axial displacement of the mixing tank 2, ensuring that the mixing tank 2 rotates smoothly and realizing the switching of the working position of the first mixing chamber 201 and the second mixing chamber 202.

[0037] This application can be used in the field of ceramic production technology, or in other fields applicable to this application.

[0038] In another embodiment: Reference Figure 4-5An improvement upon Embodiment 1: A continuous mixing device for ceramic raw materials, applied in the field of ceramic production technology. A Y-shaped three-way pipe 12 is fixedly connected to the bottom of a support frame 1. The two inlet pipes of the three-way pipe 12 correspond to the positions below the first mixing chamber 201 and the second mixing chamber 202, respectively, and each inlet pipe is equipped with an electric valve 13. A conveying pipe 14 is fixedly installed inside the support frame 1 below the mixing tank 2. The outlet of the Y-shaped three-way pipe 12 extends into the conveying pipe 14 and is rotatably connected to it. A spiral conveying rod 15 is rotatably installed inside the conveying pipe 14. A second motor 16 is fixed to one end of the conveying pipe 14, and the output shaft of the second motor 16 is fixedly connected to the spiral conveying rod 15. When the raw materials in a certain mixing chamber are mixed, the corresponding electric valve 13 is opened, and the material falls into the conveying pipe 14 through the three-way pipe 12. The second motor 16 drives the spiral conveying rod 15 to rotate, and the spiral blades push the material outward while simultaneously scraping the inner wall of the conveying pipe 14 to reduce material residue. The screw conveyor rod 15 and the three-way pipe 12 form a closed discharge channel to avoid cross-contamination when switching between different formula raw materials.

[0039] During operation, the first motor 11 drives the mixing tank 2 to rotate, aligning the feed inlet 401 of one of the mixing chambers with the fixed feed pipe 5 to inject raw materials. Subsequently, the third motor 19 starts the stirring rod 6 to mix. At the same time, the other mixing chamber can simultaneously perform feeding, stirring, or discharging operations. After one mixing chamber completes mixing, the corresponding electric valve 13 is opened to discharge the material. The chamber that has finished discharging then rotates back to the feeding position to continue the cycle, thereby achieving continuous mixing of ceramic raw materials without stopping the machine, significantly improving the effective operating time of the equipment.

[0040] However, as is well known to those skilled in the art, the working principles and wiring methods of the first motor 11, the second motor 16 and the third motor 19 are commonplace and are all conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
