Abstract

A device for preparing ultra-high purity zinc based on intelligently-controlled zone melting, including a slide platform connected with a screw through a servo control system to control movement of a heating-cooling device. A quartz tube is provided inside an induction heater to protect a melting zone. An infrared thermometer is connected to the heater, and configured to monitor temperature within the melting zone, and control power of the heater. A ring magnetic stirrer with non-contact circumferential rotation cooperates with coil to stir zinc melt. A water-cooling copper jacket is connected to two ends of the heater to cool a zinc bar, and its water inlet and outlet are connected with a water chiller. The infrared thermometer monitors temperature of the zinc bar and controls water flow of the cooling system. A lifting device is connected with a base cabinet to change inclined angle of the zinc bar.

First claim

What is claimed is:

1 . A device for preparing ultra-high-purity zinc based on intelligently-controlled zone melting, comprising:
a melting device; and a first base cabinet; wherein the melting device is arranged on a top of the first base cabinet; an interior of the first base cabinet is provided with a lifting device; the lifting device is provided with a tilt sensor, and is connected with a bottom of the melting device to change an inclined angle of the melting device; a glass cover is sleevedly provided outside the melting device, and a top of the glass cover is provided with a ventilator; an outer side of the first base cabinet is provided with a screen holder, and a control and monitoring system is provided on the screen holder; and the control and monitoring system is connected with the melting device and the lifting device.

2 . The device of claim 1 , wherein the melting device comprises a base; a clamp and a slide platform are correspondingly provided on the base; the clamp is provided with a to-be-purified test bar; a heating-cooling device, a ring magnetic stirrer and a pair of infrared thermometers are arranged on the slide platform; the heating-cooling device and the ring magnetic stirrer are sleeved on the to-be-purified test bar; and the heating-cooling device, the ring magnetic stirrer and the pair of infrared thermometers are connected with the control and monitoring system.

3 . The device of claim 2 , wherein the number of the clamp is two, and two clamps are connected with a first adjustable support and a second adjustable support, respectively; a bottom of the first adjustable support is fixedly connected with the base through a second base cabinet; and the second adjustable support is connected with a screw through a servo motor, and an end of the screw is provided with a coupling.

4 . The device of claim 2 , wherein two sliding rails are arranged in parallel on the base, and the slide platform is arranged on the two sliding rails; and a bottom of the slide platform is connected with a screw through a servo motor.

5 . The device of claim 4 , wherein an outer side of each of the two sliding rails is provided with a slide limiter.

6 . The device of claim 2 , wherein the heating-cooling device comprises a water-cooling copper jacket; the water-cooling copper jacket is sleeved on the to-be-purified test bar; a middle of the water-cooling copper jacket is provided with an induction heater; and a quartz tube is sleeved on the induction heater.

7 . The device of claim 6 , wherein the water-cooling copper jacket is correspondingly provided with a water inlet, a water outlet, an air inlet, and an air outlet; the water inlet and the water outlet are connected with a cooling system; and the air inlet and the air outlet are connected with a protective gas cylinder.

8 . The device of claim 7 , wherein an interior of the water-cooling copper jacket is provided with a spirally-grooved air channel; and an inert protective gas is configured to be fed from the protective gas cylinder to the heating-cooling device through the air inlet, and fill the heating-cooling device along the spirally-grooved air channel.

9 . The device of claim 6 , wherein the ring magnetic stirrer is provided outside the induction heater; and the ring magnetic stirrer is configured to rotate circumferentially, and move directionally with the induction heater synchronously.

10 . The device of claim 1 , wherein the lifting device comprises an actuator arranged in the first base cabinet; the actuator is connected with a first end of a connection plate through a screw; and a second end of the connection plate is connected with the base of the melting device.
