High-speed centrifugal liquid remover

Abstract

The invention relates to a high-speed centrifugal drier, which comprises a frame, a speed-adjusting motor, two support main axles, drying barrel, a frame barrel. Wherein, the support main axles are mounted on the frame; the drying barrel is the narrow-necked stainless barrel whose rotational speed is 12000r / min to reach the dynamic balance, while it is mounted on the upper ends of support main axles, and it side surface has liquid outlets; the frame barrel is fixed on the frame and sheathes the high-speed drying barrel; the bottom of frame barrel has liquid discharge holes; the speed-adjusting motor is mounted on the frame; the speed-adjusting motor via belt drives support main axles; the frame barrel is made from stainless steel or plastic; since the drying barrel is fixed on support main axles, and its rotational precision is in 0.5 mum, the stable operation speed of said invention can reach 12000r / min, especially for drying the solid chemicals that can not be heated, and the liquid content of dried solid material is under 3%.

Description

technical field [0001] The invention relates to a scientific and educational instrument, in particular to a centrifugal dehydrator. Background technique [0002] Centrifuges are inseparable from technical activities such as teaching, scientific research, testing and testing in colleges, research institutes, industrial and mining enterprises. Existing centrifuges are generally used for solid-liquid separation or separation of different liquids. But the existing centrifugal dehydrator can't separate the liquid content in the solid object. In the general solid object, its water content (or acid, lye and other liquids) is about 10%. With the improvement of test requirements, in many occasions, the less liquid content in solid objects is required, the better it can be controlled within 3%. At present, people usually use heating method and light drying method to reduce the liquid content in solid objects. The amount of liquid can meet the requirements, but this method cannot be u...

AI Technical Summary

Problems solved by technology

Some people try to use a centrifuge to achieve it, but after many tests, it is impossible to use the existing centrifuge, because there must be enough centrifugal force to separate the moisture in the solid. When the liquid is separated, the centrifugal linear speed of the dehydrator must reach more than 60 m / s. For the centrifugal drying bucket with a diameter of less than 10 cm, the speed must reach 6000-12000 rpm

With such a high rotational speed, the centrifugal dehydrator with the existing structure cannot bear it

Because the main shaft of the existing centrifugal dehydrator is a single-support structure, the main shaft of the centrifugal dehydrator is the main shaft of the motor, the drying bucket is directly fixed on the upper end of the main shaft of the motor, and the motor is fixed on the supporting frame. The speed of the motor can only be controlled at 1500 rpm Between / min and 3000rpm, if the speed is too high, the dynamic balance of the centrifuge cannot meet the requirements, the vibration of the centrifuge will increase, and it is very unsafe to use
