Description

Technical Field

[0001] The utility model belongs to the technical field of calcination in the production process of microcrystalline white fused alumina, and particularly relates to a microcrystalline white fused alumina calcination device. Background Technique

[0002] Microcrystalline white fused alumina is a white abrasive made from alumina powder through high-temperature melting. It has a slightly higher hardness than brown fused alumina and slightly lower toughness. Microcrystalline white fused alumina has the characteristics of uniform particle size composition, low magnetic substance content, high bulk density, high hardness, good toughness, high cleanliness, etc., and is suitable for surface beautification treatment of various high-end products, processes or hardware products. After sandblasting, the surface is white and free of any impurities, eliminating the trouble of cleaning. Fine-grade microcrystalline white fused alumina can be used as the first choice for polishing and grinding. It can also be used as an additive for various products, making solid and coated abrasives, wet or dry or jet sand, suitable for ultra-precision grinding and polishing in the crystal and electronics industries and making high-grade refractory materials, etc. It has the advantages of high hardness, high toughness, high wear resistance, etc., so it is widely used in the processing of difficult-to-machine materials such as tool steel, ductile stainless steel, and heat-resistant alloy steel. In the process of producing microcrystalline white fused alumina, the calcination device is an essential equipment. Through high-temperature calcination treatment, the performance of microcrystalline white fused alumina can be further improved, such as increasing the surface roughness of abrasive grains and increasing hydrophilicity. When the existing calcination device calcines microcrystalline white fused alumina, the calcination speed is slow and the heating in different areas of the calcination furnace is uneven. Therefore, a new type of calcination device is needed. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a microcrystalline white fused alumina calcination device to solve the problems in the above background technique.

[0004] The purpose of the utility model is achieved as follows: A microcrystalline white fused alumina calcination device, which includes a substrate, an auxiliary base is fixedly arranged on the upper surface of the substrate, a horizontal cylinder is fixedly arranged at the upper end of the auxiliary base, a calcination cylinder is rotatably connected inside the horizontal cylinder, and a calcination component is arranged inside the calcination cylinder; a left extension cylinder is communicated with the left end of the calcination cylinder, a right extension cylinder is communicated with the right end of the calcination cylinder, and a stabilizing component for assisting the stable rotation of the calcination cylinder is connected to the outside of the left extension cylinder; a driving component for driving the rotation of the calcination cylinder is connected to the outside of the right extension cylinder.

[0005] Further, the driving component includes a first sprocket fixedly arranged on the outside of the right extension cylinder, a motor is fixedly arranged on the upper surface of the substrate, the output shaft of the motor is connected with a transmission shaft, a vertical plate is arranged on the upper surface of the substrate corresponding to the motor, the other end of the transmission shaft is rotatably connected with the vertical plate, and a second sprocket is fixedly arranged on the outside of the transmission shaft, and the second sprocket is connected with the first chain through a chain.

[0006] Further, the stabilizing component includes a turntable fixedly arranged outside the left extension cylinder. On the upper surface of the base plate, a left matching part and a right matching part that cooperate with the turntable are fixedly arranged. The left matching part and the right matching part are used to make the turntable rotate at a stable speed.

[0007] Further, both the left matching part and the right matching part include a connecting seat. At the upper end of the connecting seat, a first support plate and a second support plate extending vertically upward are fixedly arranged. A pin shaft is fixedly arranged between the first support plate and the second support plate. A roller is rotatably connected to the outside of the pin shaft, and the outer surface of the roller contacts the outer surface of the turntable.

[0008] Further, the calcining component includes an inclined plate fixedly arranged on the inner wall of the calcining cylinder, and an arc part is fixedly arranged at the inner end of the inclined plate. The arc part is used to lift the white fused alumina being calcined inside from the lower part of the calcining cylinder to the upper part of the calcining cylinder when the calcining cylinder rotates.

[0009] Preferably, the driving component includes a first belt pulley fixedly arranged outside the right extension cylinder. On the upper surface of the base plate, a motor is fixedly arranged.

[0010] The beneficial effects of the present utility model are as follows: By setting the calcining device as a cylindrical calcining cylinder, when calcining microcrystalline white fused alumina, the calcining cylinder is heated by silicon carbide rods, and the heating of the calcining cylinder is realized through electric energy. Microcrystalline white fused alumina is placed inside the calcining cylinder. While the microcrystalline white fused alumina is heated, the calcining cylinder rotates, which can make all the space areas inside the calcining cylinder be heated evenly and have the same temperature, improving the calcining quality of microcrystalline white fused alumina. At the same time, a calcining component is arranged inside the calcining cylinder. The calcining component is used to lift the microcrystalline white fused alumina on the inner bottom surface of the calcining cylinder to the upper part inside the calcining cylinder when the calcining cylinder rotates. When the calcining component lifts the microcrystalline white fused alumina and rotates synchronously with the calcining cylinder, when reaching the highest point, the microcrystalline white fused alumina inside the calcining component falls again onto the inner bottom surface of the calcining cylinder due to the overturning of the calcining component, and this cycle is repeated, which can greatly accelerate the calcining speed of microcrystalline white fused alumina and improve production efficiency.

When calcining microcrystalline white corundum, the calcination cylinder 4 is heated by silicon carbide rods, and the heating of the calcination cylinder 4 is realized through electric energy. Microcrystalline white corundum is placed inside the calcination cylinder 4. While the microcrystalline white corundum is heated, the calcination cylinder 4 rotates, which can make all the spatial areas inside the calcination cylinder 4 be heated evenly and have the same temperature, improving the calcination quality of microcrystalline white corundum.
