Abstract

A water circulating mechanism for a water-cooled ferroalloy casting mold plate comprises a base (1), a cooling mechanism, a casting and shaping mechanism, and a central power device (2). An annular track (3) is provided at a top portion of the base. The cooling mechanism is slidably mounted on the track. The casting and shaping mechanism can flip up and down relative to the cooling mechanism. The central power device drives the cooling mechanism and the casting and shaping mechanism to synchronously perform circular motion along the track. The cooling mechanism provides cooling water to the interior of the casting and shaping mechanism by means of a pipeline, and recycles heated hot water, such that molten iron on the casting and shaping mechanism is cooled to form a granular product during the circular motion. The water circulating mechanism is applied to a granulator to eliminate the defect of a high powder rate caused by manual or mechanical crushing and finishing required in a conventional smelting-based product production process in the ferroalloy industry, thereby reducing environmental pollution and the risk of workers suffering from dust-caused occupational diseases. In addition, the invention reduces labor costs, achieves energy conservation and consumption reduction, and achieves automated casting of molten iron, cooling, and shaping of ferroalloy products produced by means of smelting.

The following describes a complete working process of the pellet machine:

First, turn on the central power unit 2 and the water pump. The central power unit 2 drives the cooling mechanism and the casting forming mechanism to make circular movements synchronously along the track on the base 1, and the water pump supplies cooling water to the water tank 5 of the cooling mechanism. In the process of the circular motion of the casting molding mechanism, the molten iron of the ladle 28 enters the pouring bucket 4 through the casting trough 27, and then the molten iron in the pouring bucket 4 is continuously poured into the ball socket on each casting template 14 of the casting molding mechanism In 16, the cold water in the cooling water channel 17 inside the casting template 14 cools and lowers the temperature of the molten iron in the ball socket 16 to form the molten iron into a granular product matching the shape of the spherical socket 16. After the granular product in the ball socket 16 is formed, the roller 20 at the end of the casting die 14 will reach the opening of the double slide bar 19 with the circular motion of the casting die plate 14 and roll under the continuous circular motion of the casting die plate 14 The shaft 20 will enter the slide groove inside the double slide bar 19 and move along the slide groove. Because the double sliding rod 19 first bends and extends upward toward the outside of the water tank 5, and then continues downwardly and outwardly toward the outside of the water tank 5, and finally upwardly bends and extends toward the inside of the water tank 5, and then continues downwardly to the inside of the water tank 5 and extends to the casting At the position of the mold plate 14 in the circular motion track where the cast iron water is to be prepared, under the guidance of the double slide bar 19 (chute), the mold plate 14 will undergo a corresponding turning action: the end of the mold plate 14 near the roller 20 is first opposed to the water tank 5 Flip up (the angle between the casting template 14 and the water tank 5 is gradually opened) to release the formed granular product, and then turn down and reset relative to the water tank 5 (the angle between the casting template 14 and the water tank 5 gradually closes ) To prepare for the next cast iron pouring. Under the action of the double slide bars 19, the mold product on the mold plate 14 is demolded and the mold plate 14 is reset after demolding. When the mold plate 14 carries out demoulding granular products and resets the turning action, the water inlet rotary joint 6 and the water outlet rotary joint 7 can ensure that the cooling water channel in the mold plate 14 can be normally cooled by water, without affecting the automatic mold release of the mold plate 14 And the reversing action of resetting, solves the problem that the casting molding mechanism automatically releases the mold when the water is put in through the pipeline, and improves the production environment and reduces the production cost. When the end of the casting template 14 close to the roller 20 is first turned upward relative to the water tank 5 to the automatic release of the granular product (after the angle between the casting template 14 and the water tank 5 is opened to a certain degree), the granular product is removed from the casting The mold plate 14 is demolded and enters the hopper 23 through the chute 22, and finally the granular product is collected in the hopper 23. Under the guidance of the double slide bar 19, the mold plate 14 that has been demolded is turned down relative to the water tank 5 until the double slide bar 19 is released and returned to the horizontal state again, preparing for the next casting molding. At this point, a work cycle ends.

The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection of the present invention Within range.
