Description

Technical Field

[0001] This application relates to the technical field of ceramic blank production, and in particular to a raw material mixing device for ceramic blank production. Background Technology

[0002] In the production of liquid ceramic blanks, it is necessary to thoroughly mix various raw materials to ensure uniform mixing. Due to the slow speed and low efficiency of manual mixing, manual mixing has been gradually replaced by mechanical mixing devices. Most existing mixing devices place the raw materials in a mixing tank and use a motor to drive the stirring rod to mix the raw materials. However, in this type of mixing device, because the stirring rod rotates in the same direction and the raw materials in the mixing tank also rotate in the same direction, it is easy to cause insufficient mixing, low mixing efficiency, and affect product quality. Utility Model Content

[0003] The purpose of this application is to provide a raw material mixing device for the production of ceramic blanks, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this application provides a raw material mixing device for ceramic blank production, which adopts the following technical solution:

[0005] A raw material mixing device for ceramic blank production includes a mixing tank, a mixing shaft, and a drive motor. The mixing shaft is rotatably disposed inside the mixing tank, and a mixing rod is fixed to the surface of the mixing shaft. The drive motor is installed at the top of the mixing tank to drive the mixing shaft to rotate. The mixing tank includes a top cover and a tank body. A reinforcing seat is fixed on the top cover, and a groove penetrating the top cover is formed on the surface of the reinforcing seat. A baffle is slidably connected in the groove. The baffle includes a vertical rod and baffle plates symmetrically and evenly fixed on both sides of the vertical rod. A reduction motor is fixedly installed on the reinforcing seat, and a gear is fixed to the output end of the reduction motor. The vertical rod has teeth evenly formed on one side of its surface corresponding to the gear, which mesh with the gear. The bottom end of the vertical rod can move to the bottom end of the mixing tank.

[0006] Preferably, the cross-section of the spoiler is triangular, and the apex of the triangle is capable of colliding with the raw material.

[0007] By adopting the above technical solution, the overall baffle is set in a triangular shape. When the tip of the triangle comes into contact with the rotating raw material, the resistance is small. When the raw material flows through the triangular baffle, a low-pressure zone will be formed behind the plate due to the geometry of the plate. After the liquid reaches the tip of the triangular plate, the flow velocity slows down and the kinetic energy is exhausted, forming a stagnation point. At this time, the liquid near the wall is strongly disturbed under the action of pressure and inertia, which causes the boundary layer to separate from the wall. After the boundary layer separates, the liquid forms a vortex behind the triangular plate, resulting in a good turbulence effect.

[0008] Preferably, the surface of the spoiler is covered with a dust cover, which is fixed to the top cover.

[0009] By adopting the above technical solutions, the dust cover can reduce dust contamination of raw materials and prevent raw materials from splashing out of the mixing tank and causing workshop pollution.

[0010] The vertical rod has a T-shaped protrusion on one side, and the sliding groove has a guide groove on the side corresponding to the T-shaped protrusion.

[0011] Preferably, a baffle is fixed at an angle near the top of the mixing tank, and the baffle is able to collide with the raw materials.

[0012] By adopting the above technical solution, the raw materials will overflow along the inner wall of the mixing tank during the mixing process. After contacting the baffle, the baffle will change its direction and rush out and fall towards the middle mixing shaft, thereby improving the mixing effect.

[0013] Preferably, in order to ensure that the vertical rod can be stably erected inside the mixing tank, the reinforcing seat extends into the tank body.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] 1. By setting up baffles, during the middle of the mixing process, the raw materials will overflow along the inner wall of the mixing tank. After contacting the baffles, they will be changed in direction by the baffles and rush out and fall towards the middle mixing shaft, thereby improving the mixing effect.

[0016] 2. By setting up the baffle, in the later stage of mixing, the geared motor drives the vertical rod to move downward. After the high-speed rotating liquid flows through the baffle, the liquid forms a vortex behind the triangular plate, which has a good turbulence effect. This allows the raw materials to be fully mixed, greatly improving the mixing efficiency and thus improving the product quality. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0021] This application discloses a raw material mixing device for ceramic blank production, referring to... Figure 1-2 The system includes a mixing tank 1, a stirring shaft 2, and a drive motor 3. The stirring shaft 2 is rotatably mounted inside the mixing tank 1, and a stirring rod is fixed to its surface. The drive motor 3 is mounted on the top of the mixing tank 1 to drive the stirring shaft 2 to rotate. The mixing tank 1 includes a top cover 11 and a tank body 12. A reinforcing seat 4 is fixed on the top cover 11. To reduce the impact of resistance on the turbulence-causing component 51, the reinforcing seat 4 extends into the tank body 12. The reinforcing seat 4 can provide sufficient reaction force to the vertical rod 51. A through-hole is formed on the surface of the reinforcing seat 4 that penetrates the top cover 11. The slide chute has a slidably connected baffle 5 inside. One side of the vertical rod 51 has a T-shaped protrusion 511, and the slide chute has a guide groove on the side corresponding to the T-shaped protrusion 511. The baffle 5 includes the vertical rod 51 and baffle plates 512 that are symmetrically and evenly fixed on both sides of the vertical rod 51. A geared motor 6 is fixedly installed on the reinforcing seat 4. A gear 61 is fixed at the output end of the geared motor 6. The surface of the vertical rod 51 corresponding to the gear 61 is evenly provided with teeth that mesh with the gear 61. The bottom end of the vertical rod 51 can move to the bottom end of the mixing tank 1.

[0022] The surface cover of the baffle 5 is equipped with a dust cover 7, which is fixed on the top cover 11. The dust cover 7 can reduce dust contamination of raw materials and prevent raw materials from splashing out of the mixing tank 1 and causing workshop pollution.

[0023] Reference Figure 1 The cross-section of the baffle 512 is triangular, and one side of the apex of the triangle can collide with the raw material. The baffle 512 is set in a triangular shape. When the apex of the triangle comes into contact with the rotating raw material, the resistance is small. When the raw material flows through the triangular baffle 512, a low-pressure zone will be formed behind the plate due to the geometry of the plate. After the liquid reaches the tip of the triangular plate, the flow velocity slows down and the kinetic energy is exhausted, forming a stagnation point. At this time, the liquid near the wall is strongly disturbed under the action of pressure and inertia, which causes the boundary layer to separate from the wall. After the boundary layer separates, the liquid forms a vortex behind the triangular plate, resulting in a good turbulence effect.

[0024] Reference Figure 1A baffle 8 is fixed at an angle near the top of the mixing tank 1, and the baffle 8 can collide with the raw materials.

[0025] During the mixing process, the raw materials will overflow along the inner wall of the mixing tank 1. After contacting the baffle 8, they will be changed in direction by the baffle 8 and will be pushed out and fall towards the middle mixing shaft 2, thereby improving the mixing effect.

[0026] The implementation principle of the raw material mixing device for ceramic blank production according to an embodiment of this application is as follows:

[0027] During the middle stage of mixing, the raw materials overflow upwards along the inner wall of the mixing tank 1. After contacting the baffle 8, they are deflected by the baffle 8 and rush out towards the middle mixing shaft 2 to be mixed again, which can improve the mixing effect. In the later stage of mixing, the reduction motor 6 drives the vertical rod 51 to move downwards. The high-speed rotating liquid raw materials come into contact with the baffle 512. The baffle 512 is set in a triangular shape. When the tip of the triangle comes into contact with the rotating raw materials, the resistance is small. When the raw materials flow through the triangular baffle 512, a low-pressure zone is formed behind the plate due to the geometry of the plate. After the liquid reaches the tip of the triangular plate, the flow rate slows down and the kinetic energy is exhausted, forming a stagnation point. At this time, the liquid near the wall is strongly disturbed under the action of pressure and inertia, causing the boundary layer to separate from the wall. After the boundary layer separates, the liquid forms a vortex behind the triangular plate, which has a good turbulence effect, thus enabling the raw materials to be fully mixed, greatly improving the mixing efficiency and thus improving the product quality.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
