Centrifugal air shower drying machine

Abstract

The invention provides a centrifugal air shower drying machine which comprises a box body, a box cover, a frame arranged in the box body, a motor installed on the frame, a centrifugal device driven by the motor and a hot-air blower arranged on the side portion of the box body. The centrifugal device comprises a fly wheel disc driven by a motor output shaft and rotating in a horizontal plane, a hanging basket arranged along the periphery of the outer edge of the fly wheel disc and hinged to the fly wheel disc and a material basket installed in the hanging basket. The centrifugal air shower drying machine has the advantages of being scientific in design, efficient in production and high in yield, decreasing working procedures and reducing the cost.

Description

technical field [0001] The invention relates to a dryer, in particular to a centrifugal air shower dryer in artificial crystal wafer dehydration and drying equipment. Background technique [0002] The general process of cleaning crystals in the existing artificial crystal processing industry is: ① Clean the crystal chips with ionized water in an ultrasonic cleaner; ② Use high-purity industrial alcohol to dehydrate the crystal chips; ③ Use a high-power electric heating oven Dry the alcohol on the crystal surface. [0003] This method has the following disadvantages: [0004] 1. The processing cycle is long and requires three processing procedures; [0005] 2. The yield rate is unstable. If the alcohol drying is not thorough, it will cause watermark pollution and other phenomena. In addition, the temperature difference between the crystal chips is large, causing some crystal chips to crack, and the pass rate is low; [0006] 3. The cost is high. In the second step, a large ...

AI Technical Summary

Problems solved by technology

[0004] 1. The processing cycle is long and requires three processing procedures;

[0005] 2. The yield rate is unstable. If the alcohol drying is not thorough, it will cause watermark pollution and other phenomena. In addition, the temperature difference between the crystal chips is large, causing some crystal chips to crack, and the pass rate is low;

[0006] 3. The cost is high. In the second step, a large amount of high-purity alcohol is used to dehydrate the crystal wafer. Due to the high cleanliness process requirements on the product surface, high-purity alcohol cannot be reused, resulting in the consumption of a large amount of high-purity alcohol every day.

[0007] In the case of urgent orders for production tasks, the above-mentioned shortcomings become more and more prominent, which can easily lead to the situation that the order cannot be completed on time, affecting the reputation and interests of the manufacturer
