Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic production technology, and in particular to an automatic powder embedding device for special ceramic production blanks. Background Technology
[0002] Special ceramics require the embedding of powder into the raw material during manufacturing. This involves spraying or coating alumina powder onto the outer surface of the special ceramic raw material to achieve properties such as high temperature resistance and high strength in the finished product.
[0003] In existing technologies, powder is mainly sprayed onto the surface of the blank in atomized form by a high-pressure material pump mechanism, and then the powder is recovered by a powder conveyor belt recovery mechanism. First, the special ceramic blank is placed on a conveyor belt with through holes on its surface. The conveyor belt is driven by a motor to move at a constant speed to achieve continuous conveying of the blank. Then, alumina powder is evenly sprayed onto the surface of the special ceramic blank through a powder mist nozzle, while the powder scattered on the conveyor belt falls into the material drop plate below through the through holes and is finally collected by the collection box, reducing raw material waste.
[0004] However, the above-mentioned existing technical solutions have the following shortcomings: the powder recovered by the conveyor belt will form hard lumps under the vibration of the conveyor belt, which will lead to a decrease in the quality of the recovered powder and make it unusable.

[0018] 1.

[0028] Special ceramics require powder embedding during production. This involves spraying or coating alumina powder onto the outer surface of the ceramic blank. This is primarily achieved by a pump mechanism that atomizes the powder and sprays it onto the blank surface. A powder collection mechanism then recovers the powder. First, the ceramic blank is placed on a conveyor assembly, which includes a conveyor belt 5 with through-holes for powder collection. The powder is then conveyed through the conveyor belt 5 into the through-holes of the working box 1. A motor drives the conveyor belt 5 to move at a constant speed, ensuring continuous transport of the blank. Alumina powder is then evenly sprayed onto the surface of the ceramic blank through powder mist nozzles 13 located on the side wall of the working box 1. Powder scattered on the conveyor belt 5 falls through the through-holes into the lower guide channel 2 and is finally collected by the collection box 11, reducing material waste.
[0029] Example:
[0030] Reference Figures 1-4 An automatic powder-burying device for special ceramic raw materials is disclosed. A guiding channel 2 is provided at the bottom of the working box 1. Powder from the conveyor belt 5 falls into the guiding channel 2 through through holes. The inner wall inclination angle of the guiding channel 2 ranges from 40° to 60°. In this device, the inner wall inclination angle of the guiding channel 2 is designed to be 50°, allowing the scattered powder to smoothly slide to the bottom of the guiding channel 2, preventing powder accumulation in the channel and ensuring smooth and efficient powder recovery. Furthermore, the choice of this inclination angle also considers the powder's flowability and gravity, ensuring that the powder does not splash due to excessive speed during the descent, nor does it clog the channel due to insufficient speed, thus improving production efficiency. A crushing cylinder 3 is also provided at the bottom of the guiding channel 2. The crushing cylinder 3 is equipped with three sets of crushing rollers 4. The axes of each set of crushing rollers 4 are arranged in a triangular pattern, and a collision gap is formed between the crushing rollers 4 and the crushing cylinder 3. When the powder slides into the crushing cylinder 3 through the guide channel 2, the three sets of crushing rollers 4 in the crushing cylinder 3 can be driven to rotate by a motor. Since the axes are arranged in a triangular pattern, the powder is subjected to multi-directional collisions in the collision gap, which effectively achieves crushing. At the same time, it can also avoid excessive powder blockage and ensure the continuous and stable operation of the device. A collection box 11 is also set on the ground. The collection box 11 is fixedly connected to the crushing cylinder 3 through a conveying component. The cavity of the collection box 11 is connected to the nozzle 13 through a conveying mechanism. The powder in the collection box 11 can be pumped into the nozzle 13 for reuse through the conveying mechanism.
[0031] In the above scheme, the three sets of crushing rollers 4 inside the crushing cylinder 3 are driven by a motor to rotate, ensuring that the powder is fully crushed in the collision gap, providing high-quality raw materials for the preparation of ceramic blanks. At the same time, the storage box 11 is fixedly connected to the crushing cylinder 3 through the conveying component, forming a closed-loop powder recycling system, which effectively crushes the hard lumps of powder formed under the vibration of the conveyor belt 5, avoids excessive powder blockage, and ensures the continuous and stable operation of the device.
[0032] To further improve the powder crushing effect, the above-mentioned conveying assembly includes a conveying cylinder 6 fixedly connected to the bottom of the crushing cylinder 3. A connecting shaft 7 is rotatably connected inside the conveying cylinder 6, and a crushing blade 8 is fixedly connected to the circumference of the connecting shaft 7. The conveying cylinder 6 is connected to the receiving box 11 through the feeding channel 9. A rotating shaft 10 is fixedly connected to the crushing roller 4. The rotating shaft 10 is rotatably connected to the crushing cylinder 3, and the rotating shaft 10 and the connecting shaft 7 are connected by a transmission belt, so that the connecting shaft 7 and the rotating shaft 10 rotate in the same direction. The end of the rotating shaft 10 extends to the outside of the crushing cylinder 3. Equipped with drive pulleys, each set of drive pulleys is connected by a belt drive, enabling the three sets of rotating shafts 10 to rotate synchronously. The feeding channel 9 can be set on the left or right side of the conveying cylinder 6. When set on the right side, the rotating shaft 10 can rotate counterclockwise to convey the powder. When set on the left side, the rotating shaft 10 can rotate clockwise to convey the powder. During the conveying process, the powder can also be further crushed, cut, and pulverized to ensure that the particle size of the powder is more uniform and fine, and to avoid accumulation and blockage during the powder conveying process.
[0033] Furthermore, the aforementioned conveying assembly includes a high-pressure material pump 12 fixedly connected to the storage box 11. The input end of the high-pressure material pump 12 is connected to the cavity of the storage box 11 through a pipe, and the output end of the high-pressure material pump 12 is fixedly connected to the nozzle 13 through a pipe. The high-pressure material pump 12 can convey the powder in the storage box 11 to the nozzle 13 at a certain pressure. The nozzle 13 can be an atomizing nozzle 13, which is responsible for evenly spraying the powder onto the blank to realize the automatic powder embedding process.
[0034] Crushing teeth are provided on the outer periphery of the crushing roller 4 and the inner wall of the crushing cylinder 3. The crushing teeth are conical in shape. The conical structure of the crushing teeth makes it easier for the powder to pass through the gaps between the teeth when it is squeezed, thereby achieving a better crushing effect. At the same time, the conical crushing teeth also have a certain self-cleaning function, which can reduce the residual powder on the inner wall of the crushing cylinder 3 and the outer periphery of the crushing roller 4.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
