This special ceramic slurry shows great application potential in many fields, from high-temperature components in aerospace to high-performance ceramic parts in the electronics industry, and to biomedical ceramics in the medical field.

[0003] Existing solidified silicon nitride ceramic slurry mixing devices use multiple independent stirring components to stir the raw materials during the initial mixing and stirring of the raw materials. The independent stirring components require corresponding drive motors to provide them with energy. During long-term preparation, such devices will consume a large amount of energy and put a certain amount of pressure on the power grid.

[0004] Therefore, there is an urgent need to provide a mixing device for preparing photocured silicon nitride ceramic slurry to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a mixing device for preparing light-cured silicon nitride ceramic slurry.

[0006] In order to solve the above technical problems, the present invention adopts a technical solution: providing a mixing device for preparing light-cured silicon nitride ceramic slurry, comprising a tank body, a protective cover fixedly connected to the center of the top of the tank body, a drive motor installed inside the protective cover, an output end of the drive motor fixedly connected to a main rotating rod, and an outer wall of the main rotating rod respectively fixedly connected to an auger shaft and a stirring bar;

[0007] A mounting block is fixedly connected to the top of the tank body, a synchronous stirring mechanism is provided on the top of the mounting block, two stirring tanks are installed inside the tank body, a feed pipe is installed inside each stirring tank, a plurality of reagent kits are fixedly connected to the outer wall of the tank body, a reagent tube is installed on the inner side of each reagent kit, a spray assembly is installed on the inner wall of the two stirring tanks, a discharge pipe is fixedly connected to the bottom of one of the stirring tanks, and a liquid discharge pipe is fixedly connected to the bottom of the other stirring tank, and both the discharge pipe and the liquid discharge pipe are installed with electronic valves;

[0008] The bottom of the tank body is rotatably connected to a mechanical rotation switch.

[0009] The utility model is further configured as follows: the synchronous stirring mechanism includes a driving gear ring installed on the top of the mounting circular block, the top of the mounting circular block is rotatably connected to a first adjusting gear plate, the outer wall of the first adjusting gear plate is rotatably connected to a first driven gear plate, the bottom of the first driven gear plate is fixedly connected to a first rotating rod, the outer wall of the first rotating rod is installed with a plurality of turbine-type stirring paddles, the top of the mounting circular block is rotatably connected to a second gear plate, the outer wall of the second gear plate is rotatably connected to a second driven gear plate, the bottom of the second driven gear plate is fixedly connected to a second rotating rod, and the outer wall of the second rotating rod is installed with a plurality of spiral stirring paddles.

[0010] Through the above technical solution, when the driving motor is rotating, the driving motor will drive the active gear ring to rotate, and the rotation of the active gear ring will synchronously drive the first adjusting gear plate and the second gear plate to rotate, and the first adjusting gear plate will drive the first driven gear plate to rotate, and the first driven gear plate will drive the first rotating rod and the turbine stirring paddle to rotate to stir the raw materials inside the corresponding mixing tank. When the second gear plate rotates, it will also drive the second driven gear plate to rotate synchronously, and finally drive the second rotating rod and multiple spiral stirring paddles to rotate, and drive the gear group to rotate through the driving motor to meet the stirring of two different mixing tanks at different speeds.

[0011] The utility model is further configured as follows: the driving gear ring is connected to the driving motor.

[0019] The utility model is further configured as follows: a photoinitiator and a plasticizer are respectively installed inside the other two test kits.

[0020] Through the above technical solution, the photoinitiator can cure the coating in a few seconds or even shorter time, thereby improving production efficiency. For some hard and brittle materials, the plasticizer can improve their toughness and reduce the risk of breakage during use.

[0021] The beneficial effects of the utility model are as follows:

[0022] 1. The utility model designs a synchronous stirring mechanism, which uses a driving motor to drive multiple gear plates of different diameters to rotate, so as to achieve stirring at different speeds inside two different stirring tanks. Only one output source is needed to stir different raw materials, which reduces energy loss to a certain extent.

[0023] 2. The utility model installs different types of stirring paddles in different stirring tanks. Due to the particularity of the raw materials and additives, when preparing silicon nitride mixed powder, the spiral stirring paddle can fully mix the powder and dispersant at a lower speed while avoiding powder flying. When preparing photosensitive resin, the turbine stirring paddle can generate a strong shear force to fully mix the photosensitive resin and other additives, so that the initial mixing of the two is fully stirred and mixed, which is convenient for subsequent stirring and mixing, and the quality of the prepared light-cured silicon nitride ceramic slurry is improved.

[0029] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0030] See also Figure 1 and Figure 2 A mixing device for preparing light-cured silicon nitride ceramic slurry includes a tank body 1, a protective cover 2 is fixedly connected to the center position of the top of the tank body 1, a driving motor 3 is installed inside the protective cover 2, the output end of the driving motor 3 is fixedly connected to the main rotating rod 4, the outer wall of the main rotating rod 4 is respectively fixedly connected to the dragon shaft 5 and the stirring bar 6, and the inside of the tank body 1 is fixedly connected to the top position. A mounting round block 7 is fixedly connected.

[0031] like Figure 3 and Figure 4As shown, a synchronous stirring mechanism 8 is provided on the top of the mounting block 7. The synchronous stirring mechanism 8 includes a driving gear ring 801 mounted on the top of the mounting block 7. The driving gear ring 801 is connected to the driving motor 3. The driving motor 3 can usually provide a stable and powerful power source. When the driving gear ring 801 is connected to the driving motor 3, efficient power transmission can be achieved, and the rotational motion of the driving motor 3 can be directly transmitted to the driving gear ring 801. The top of the mounting block 7 is rotatably connected to the first adjusting gear plate 802, and the outer wall of the first adjusting gear plate 802 is rotatably connected to the first driven gear plate 803. The bottom of the first driven gear plate 803 is fixedly connected to the first rotating rod 804, and the outer wall of the first rotating rod 804 is installed with a plurality of turbine stirring paddles 805. The top of the mounting block 7 is rotatably connected to the second gear plate 806, and the outer wall of the second gear plate 806 is rotatably connected to the second driven gear plate 807. The diameters of the first adjusting gear plate 802 and the first driven gear plate 803 gradually decrease. The diameters of the second gear plate 806 and the second driven gear plate 807 gradually increase. This diameter change allows different speed outputs to be achieved as needed during the transmission process. The first adjusting gear plate 802 and the first driven gear plate 803 with smaller diameters can provide higher speeds when cooperating with other gears, which are suitable for working conditions requiring rapid movement, while the second gear plate 806 and the second driven gear plate 807 with larger diameters can output lower speeds to meet different speed production requirements. The driving gear ring 801 is meshed with the first adjusting gear plate 802 and the second gear plate 806. Through the meshing connection, the first adjusting gear plate 802 can transmit power from one component to the first adjusting gear plate 802 and the second gear plate 806 meshed with it. This direct mechanical connection ensures efficient power transmission and reduces energy loss. The bottom of the second driven gear plate 807 is fixedly connected to a second rotating rod 808, and the outer wall of the second rotating rod 808 is equipped with multiple spiral stirring paddles 809.

[0032] like Figure 3 and Figure 4 As shown, when the drive motor 3 is rotating, the drive motor 3 will drive the active gear ring 801 to rotate, and the rotation of the active gear ring 801 will synchronously drive the first adjusting gear plate 802 and the second gear plate 806 to rotate, and the first adjusting gear plate 802 will drive the first driven gear plate 803 to rotate, and the first driven gear plate 803 will drive the first rotating rod 804 and the turbine stirring paddle 805 to rotate, so as to stir the raw materials inside the corresponding stirring tank 9. When the second gear plate 806 rotates, it will also drive the second driven gear plate 807 to rotate synchronously, and finally drive the second rotating rod 808 and multiple spiral stirring paddles 809 to rotate, and drive the gear group to rotate through the drive motor 3 to meet the stirring of two different stirring tanks 9 at different speeds.

[0033] like Figure 1 and Figure 2 As shown, two stirring tanks 9 are installed inside the tank body 1, and a feed pipe 10 is installed inside each stirring tank 9. A plurality of reagent kits 11 are fixedly connected to the outer wall of the tank body 1. A dispersant is installed inside one of the reagent kits 11. The dispersant can increase the contact area between the raw materials and the reagents, thereby accelerating the reaction speed. This can shorten the detection time and improve work efficiency. The other two reagent kits 11 are respectively installed with a photoinitiator and a plasticizer. The photoinitiator can cure the coating in a few seconds or even shorter time, thereby improving production efficiency. For some hard and brittle materials, the plasticizer can improve its toughness and reduce the risk of breakage of the material during use. A reagent tube 12 is installed on the inside of each reagent kit 11. A spray assembly 13 is installed on the inner wall of the two stirring tanks 9. A discharge pipe 14 is fixedly connected to the bottom of one stirring tank 9, and a liquid discharge pipe 15 is fixedly connected to the bottom of the other stirring tank 9. The discharge pipe 14 and the liquid discharge pipe 15 are both installed with electronic valves 16. The bottom of the tank body 1 is rotatably connected to a mechanical rotary switch 17.

[0034] When the present invention is in use, the staff needs to input the corresponding raw materials into the corresponding stirring tank 9 through the feeding pipe 10, input silicon nitride powder into one of the stirring tanks 9, and the reagent kit 11 paired with it will input the dispersant into the stirring tank 9 through the reagent tube 12, and input the light curing value into the other stirring tank 9 through the feeding pipe 10, and the two paired reagent kits 11 will inject the photoinitiator and plasticizer into it. While the raw materials are being input, the driving motor 3 will also drive the synchronous stirring mechanism 8 to rotate, and the corresponding gear plates will reach different diameters through the gear plates of different diameters. The same rotation speed is used to rotate the raw materials in different stirring tanks 9 at different speeds. After the raw materials in the two stirring tanks 9 are stirred to a certain degree, the corresponding electronic valve 16 is opened, and the mixture of silicon nitride powder and dispersant that has been preliminarily stirred is added to the prepared photosensitive resin. The dragon shaft 5 and the stirring bar 6 of the main rotating rod 4 fully stir the two until they become a photocurable silicon nitride ceramic slurry. Then, the mechanical rotary switch 17 is turned to load the photocurable silicon nitride ceramic slurry. Finally, the spray component 13 is turned on to clean the inside of the device to ensure the cleanliness of the inside of the device.
