Technical Field

The invention belongs to the field of non-ferrous metal smelting and casting, and particularly relates to intelligent zinc ingot quantitative casting devices and methods.

Background

The method comprises the steps of obtaining pure zinc sheets by an electrolytic zinc process, wherein the zinc sheets are placed in an industrial furnace to be heated and melted into zinc liquid, and then the zinc liquid in the industrial furnace is cast on a zinc ingot mould by a double-scoop zinc scooping device with the publication number of CN201346617Y as disclosed in 2009.11.18. the zinc sheets are intermittently added into the industrial furnace by workers and the melting of the zinc sheets needs time, so the height of the zinc liquid in the industrial furnace is changed, the turning angle of each scoop zinc liquid is and the casting process is continuous, therefore, the mass of the zinc ingot formed by each casting cannot be kept , the weight error of the zinc ingot of 25Kg level at present is +/-2 Kg, and the large mass error seriously affects the quality of the zinc ingot, so the method mainly solves the quantitative casting problem in the zinc ingot casting process.

Disclosure of Invention

In order to overcome the technical problems, the invention provides intelligent zinc ingot quantitative casting devices and methods by adjusting the rotating angle and the rotating speed of the ladle according to the liquid level height of the zinc liquid in real time so that the mass of the zinc liquid in the ladle before each casting is samples.

The invention adopts the following specific technical scheme:

intelligence zinc ingot ration casting device, including rocker mechanism, rocker mechanism includes connecting rod and connecting rod two, and connecting rod connects drive arrangement, and the two spoons of connecting rod connection, the spoons of spoons end stretch into the industrial furnace in, ends can turn to zinc ingot mould top in addition, set up liquid level measurement device in the industrial furnace, and liquid level measurement device all is connected to control system with drive arrangement, and zinc ingot mould below sets up the conveyer belt.

, the driving device is servo motor.

, the liquid level measuring device adopts a liquid level sensor to float on the surface of the high-temperature zinc liquid, monitors the liquid level height change value in real time and transmits the liquid level height value to the control system.

And , selecting the control system to be a programmable logic controller.

, the control system sends out command according to the liquid level height signal to make the driving device drive the rocker mechanism, and the rocker mechanism drives the scoop to scoop up the liquid zinc at fixed angle.

And , rotating the ladle to the position right above the zinc ingot mould after the ladle is filled with the zinc liquid, and beginning casting until the zinc liquid in the ladle is completely cast.

, arranging a fixed rod, a connecting rod mounting seat and a casting opening on the ladle, and enabling the zinc liquid to flow into the zinc ingot mould on the conveyor belt through the casting opening.

, the scoop fixing rod is fixedly arranged on the scoop and is connected with the scoop mounting seat arranged outside the industrial furnace through a rotating shaft.

, the link of the rocker mechanism is hinged to the second link, which is fixedly connected to the link mounting seat of the scoop.

Zinc ingot quantitative casting method based on the device, comprising the following steps:

s1: measuring the height H of the liquid level;

s2: judging that the liquid level height H is more than or equal to H₁If yes, the angle of the scoop is controlled to be α₁Angular velocity of rotation of omega₁；

S3: judging the height H of the liquid level₂≤H＜H₁If yes, the angle of the scoop is controlled to be α₂Angular velocity of rotation of omega₂；
