Description

Technical Field

[0001] This utility model relates to the field of ceramic technology, specifically a ceramic raw material stirring device. Background Technology

[0002] Ceramic raw materials are typically composed of a mixture of various mineral powders such as clay, quartz, and feldspar. Stirring ensures that the different raw material particles come into full contact and are evenly distributed, preventing instability in the body's properties due to uneven composition, such as insufficient localized strength or significant color differences after sintering. Stirring also regulates the moisture content of the raw material, allowing water to penetrate evenly and form a fine-textured slurry or lump. This facilitates subsequent forming operations (such as slip casting and throwing) and prevents cracking or sticking due to uneven moisture distribution. Stirring effectively removes air from the raw material, reducing internal air bubbles and preventing them from causing cracking or uneven surfaces during high-temperature expansion during sintering. For glaze preparation, stirring ensures that the components of the glaze are fully integrated, resulting in a uniform glaze layer after application, thus improving the gloss and decorative effect of the finished ceramic product. In short, stirring lays the foundation for the forming quality and final sintering effect of the ceramic body and is a crucial step in ensuring the quality of ceramic products.

[0003] Chinese patent application number CN202323613971.7 discloses a novel stirring device. The key technical features include: a base with a stirring tank mounted on its top surface, and several support columns fixedly installed on the top surface of the base. During use, a first drive motor can be activated to rotate the side shaft and stirring blades. The opposing operation of the two stirring devices generates a strong hydrodynamic effect within the stirring tank, promoting the mixing of ceramic raw materials. Simultaneously, it effectively reduces centrifugal force, thus mitigating the deposition of raw materials near the outer edge of the stirring tank, helping to avoid dead zones and improving mixing uniformity. By covering the top surface of the stirring tank with a side cover, the dual-shaft drive motor and spiral blades are positioned between the two stirring devices. Activating the dual-shaft drive motor rotates the spiral blades, further mixing the ceramic raw materials. Simultaneously, the spiral blades push the ceramic raw materials to the two stirring devices, achieving a comprehensive and uniform mixing effect.

[0004] Existing technologies use multiple sets of motors for driving, which makes coordinated operation difficult in practical applications and increases production and maintenance costs, hindering market promotion.

[0005] In summary, this utility model provides a ceramic raw material stirring device to solve the above problems. Utility Model Content

[0006] This invention provides a ceramic raw material stirring device that uses a separate power source to drive multiple components, thereby solving the problems of high difficulty in coordinating the operation of multiple motors and high production and maintenance costs in the prior art.

[0007] The specific technical solution of this utility model is as follows:

[0008] A ceramic raw material stirring device includes a main frame. A drive motor is mounted on the side of the main frame. A first transmission wheel is fixedly connected to the output end of the drive motor. A first transmission belt is meshed with the side of the first transmission wheel. A second transmission wheel is meshed with one side of the first transmission belt. A rotating column is fixedly connected to the side of the second transmission wheel. A third transmission wheel is fixedly connected to one end of the rotating column. A second transmission belt is meshed with the side of the third transmission wheel. A fourth transmission wheel is meshed with one side of the second transmission belt. A first connecting column is fixedly connected to the side of the first transmission wheel near the main frame. A first spiral column is fixedly connected to the side of the first connecting column. A plurality of shearing gears are rotatably connected to the surface of the first spiral column. A second connecting column is fixedly connected to the side of the fourth transmission wheel near the main frame. A second spiral column is fixedly connected to the side of the second connecting column.

[0009] In this invention, the main function of the first and second helical columns is to generate axial pushing flow. The rotation of the shearing gear induces radial turbulence, such as eddies in the tooth gaps. The superposition of the two can form a three-dimensional mixed flow field, breaking the "pump flow" defect caused by the single axial flow of the helical column, promoting the lateral diffusion of ceramic particles and additives, and avoiding heavy particle sedimentation caused by centrifugal force. The drive motor, as a separate power source, directly drives the first transmission wheel, the first connecting column, and the first helical column to rotate. It also uses the first transmission belt, the second transmission wheel, the rotating column, the third transmission wheel, and the second transmission belt to drive the fourth transmission wheel to rotate, thereby driving the second connecting column and the second helical column to rotate. This solves the problems of high difficulty in coordinating the operation of multiple motors and high production and maintenance costs in the prior art.

[0010] In a preferred embodiment, a support frame is rotatably connected to the middle of the rotating column, and the side of the support frame is fixedly connected to the main frame.

[0011] In a preferred embodiment, a top cover is detachably connected to the top of the main frame, and a feed inlet is provided below the top cover.

[0012] In a preferred embodiment, a discharge port is provided on one side of the bottom of the main frame, and a discharge ramp is fixedly connected below the discharge port.

[0013] In a preferred embodiment, a mixing tank is provided on the inner side of the main frame.

[0014] In a preferred embodiment, a heating cavity is provided at the bottom of the main frame.

[0015] In this invention, the heating chamber has an independent filling port, which can be filled with materials to adjust the temperature according to the processing requirements of ceramic raw materials, thereby changing the temperature inside the device.

[0016] In a preferred embodiment, an exhaust pipe is provided on one side of the top of the main frame.

[0017] In this invention, temperature changes inside the device can cause the gas to expand and contract. At this time, the exhaust pipe can be used to balance the gas pressure inside and outside the device.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This utility model effectively solves the "plunger flow" defect of traditional spiral stirring by using a composite flow field design of axial pushing and radial turbulence, that is, the material only flows in one direction along the axial direction and there is insufficient lateral mixing. The superposition of axial flow and radial flow forms a complex mixing flow field, which can efficiently mix ceramic particles and additives, avoid heavy particle sedimentation caused by centrifugal force, and significantly improve the mixing uniformity.

[0020] 2. This utility model uses a single drive motor and a multi-stage transmission structure to drive the first and second helical columns to rotate simultaneously with only one power source. This design simplifies the power system, reduces equipment manufacturing costs, avoids the technical difficulties of multi-motor synchronous control, and significantly improves the convenience of production and maintenance.

Detailed Implementation

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0028] like Figure 1-5 As shown, this utility model provides a ceramic raw material stirring device, including a main frame 1. A drive motor 2 is arranged on the side of the main frame 1. A first transmission wheel 3 is fixedly connected to the output end of the drive motor 2. A first transmission belt 4 is meshed with the side of the first transmission wheel 3. A second transmission wheel 5 is meshed with one side of the first transmission belt 4. A rotating column 6 is fixedly connected to the side of the second transmission wheel 5. A third transmission wheel 8 is fixedly connected to one end of the rotating column 6. A second transmission belt 9 is meshed with the side of the third transmission wheel 8. A fourth transmission wheel 10 is meshed with one side of the second transmission belt 9. A first connecting column 11 is fixedly connected to the side of the first transmission wheel 3 near the main frame 1. A first spiral column 12 is fixedly connected to the side of the first connecting column 11. A plurality of shearing gears 13 are rotatably connected to the surface of the first spiral column 12. A second connecting column 14 is fixedly connected to the side of the fourth transmission wheel 10 near the main frame 1. A second spiral column 15 is fixedly connected to the side of the second connecting column 14.

[0029] A support frame 7 is rotatably connected to the middle of the rotating column 6, and the side of the support frame 7 is fixedly connected to the main frame 1.

[0030] The top of the main frame 1 is detachably connected to a top cover 16, and a feed port 17 is provided below the top cover 16.

[0031] A discharge port 18 is provided on one side of the bottom of the main frame 1, and a discharge ramp 19 is fixedly connected below the discharge port 18.

[0032] A mixing tank 20 is installed on the inner side of the main frame 1.

[0033] A heating chamber 21 is provided at the bottom of the main frame 1.

[0034] An exhaust pipe 22 is provided on one side of the top of the main frame 1.

[0035] The working principle of this utility model is as follows: After the drive motor 2 starts as the sole power source, it drives the first transmission wheel 3 through its output end; the first transmission wheel 3 transmits power to the second transmission wheel 5 through the first transmission belt 4, and the second transmission wheel 5 rotates in the same direction as the first transmission wheel 3, thereby driving the rotating column 6 to rotate around its axis. The middle part of the rotating column 6 is fixed by the support frame 7 to ensure rotational stability; the third transmission wheel 8 at the other end of the rotating column 6 rotates synchronously with the rotating column 6, and drives the fourth transmission wheel 10 to rotate through the second transmission belt 9. The first transmission wheel 3 directly drives the first connecting column 11 and the first spiral column 12 to rotate in the same direction, while the fourth transmission wheel 10 drives the second connecting column 14 and the second spiral column 15 to rotate, forming a rotating state of two spiral columns.

[0036] When the first spiral column 12 and the second spiral column 15 rotate in opposite directions, the spiral blades push the material to move axially. When the shearing gear 13 on the surface of the first spiral column 12 rotates with the spiral column, the gap between the teeth cuts the material, inducing radial vortices and forcing the material to diffuse in the horizontal direction. The superposition of axial convection and radial vortices forms a three-dimensional mixed flow field, which breaks the "plunger flow" defect of traditional spiral stirring, promotes the lateral diffusion of ceramic particles and additives of different densities, and avoids the sedimentation of heavy particles due to centrifugal force.

[0037] The heating chamber 21 is located at the bottom of the main frame 1. A heat-conducting medium is injected through an independent filling port. After the external heat source heats the medium, the heat is conducted to the material through the stirring tank 20, thereby controlling the temperature inside the device and adapting to the processing requirements of different raw materials.

[0038] When the material releases gas during the heating process of the heating chamber 21, the exhaust pipe 22 automatically discharges or draws in air to balance the air pressure inside and outside the device and prevent seal failure or equipment deformation caused by thermal expansion and contraction.
