[0002] Steel castings refer to parts made of cast steel, which have similar properties to cast iron, but better strength than cast iron. In order to improve the strength and yield of the casting, various additives are often added during the smelting of steel castings. When adding additives, a feeding device is required.
[0003] Chinese patent N219199983U discloses a smelting furnace feeding device, including a furnace body and a furnace cover arranged at the upper end of the furnace body, a hollow interlayer is arranged on the furnace body wall; a feeding port is arranged on the furnace cover and a feeding tube is installed at the upper end of the feeding port; it is used to add metal materials into the smelting furnace; a feeding component is slidably installed on the feeding tube and the inner cavity of the feeding tube is always blocked during feeding, so as to control the metal materials added into the feeding tube; a control component is installed on the furnace cover and is detachably connected to the feeding component, so as to control the feeding component to slide back and forth on the feeding tube.
[0004] In the above-mentioned patent, when the electric push rod drives the second baffle to gradually enter the feeding barrel, the first baffle will gradually withdraw from the feeding barrel, and when the first baffle and the second baffle move reciprocatingly horizontally, the blockage of the feeding barrel will be released. At this time, the heat in the furnace body will dissipate upward to the position between the first baffle and the second baffle, and then the heat enters the air through the gap between the first baffle and the feeding barrel, so that the heat of the furnace body is dissipated from the furnace body, thereby reducing the effect of preventing heat loss. Therefore, a technical measure is proposed to solve the problem that when the first baffle and the second baffle move reciprocatingly horizontally, the blockage of the feeding barrel will be released, so that the heat of the furnace body is dissipated from the furnace body, thereby reducing the effect of preventing heat loss.

The circular holes 7 are distributed, the circular holes 7 are slidably connected with the connecting rod 5, the connecting rod 5 is connected with the push plate 4, the end of the connecting rod 5 away from the push plate 4 is connected with the extrusion plate 13, the side of the extrusion plate 13 away from the connecting rod 5 is equipped with two groups of symmetrically distributed springs 14, the other end of the spring 14 is installed in the extrusion box 8, the side of the extrusion box 8 is provided with a clamping hole 9, the extrusion box 8 is provided with an empty groove 18 for installing the spring 14 and the extrusion plate 13, two groups of symmetrically distributed scrapers 15 are installed in the box body 2, the scraper 15 is above the clamping groove 16, the upper part of the heat insulation plate 11 is connected with the sealing plate 12, the upper surface of the sealing plate 12 is in contact with the scraper 15, and the heat insulation The plate 11, the sealing plate 12 are fixedly connected with the extrusion plate 13, and the heat insulation plate 11, the sealing plate 12 are slidably adapted with the card hole 9 and the card slot 16. When using the induction furnace 1 to melt the cast steel, the raw materials are put into the induction furnace 1, and the induction furnace 1 is started to melt the raw materials. When additives need to be added, the additives are measured and broken up into small pieces suitable for the cavity 17, and then the rotating plate 10 is rotated to drive the box cover 3 to rotate, and the box cover 3 is rotated and screwed out of the box body 2, and then the measured and broken additives are put into the box body 2, and then the additives are put into the induction furnace 1. The specific method is to press the push plate 4 in the direction of the box body 2 to drive The push plate 4 moves horizontally, and the push plate 4 drives the connecting rod 5 to move horizontally. The connecting rod 5 drives the extrusion plate 13 to move horizontally. When the extrusion plate 13 moves horizontally, it squeezes the spring 14. When the extrusion plate 13 moves horizontally, it also drives the sealing plate 12 and the heat insulation plate 11 to move horizontally into the slot 16. When the sealing plate 12 and the heat insulation plate 11 move horizontally into the slot 16, the upper surface of the sealing plate 12 contacts the scraper 15, and the scraper 15 pushes the additive into the induction furnace 1. When the additive enters the induction furnace 1, the push plate 4 is released, and the heat insulation plate 11 and the sealing plate 12 re-seal the induction furnace 1 under the rebound action of the spring 14.
[0027] Working principle: when using the induction furnace 1 to melt steel castings, the raw materials are placed in the induction furnace 1, and the induction furnace 1 is started to melt the raw materials. When additives need to be added, the additives are measured and broken up into small pieces suitable for the cavity 17, and then the rotating plate 10 is rotated to drive the box cover 3 to rotate, and the box cover 3 is rotated and screwed out of the box body 2, and then the measured and broken up additives are placed on the box body 2. At this time, under the blocking effect of the sealing plate 12, the additives are above the sealing plate 12, and under the blocking of the heat insulation plate 11, the heat in the induction furnace 1 will not be dissipated upward into the air (reducing heat loss is conducive to improving thermal efficiency and reducing unit energy consumption). When the additives completely enter the box body 2, the rotating plate 10 is rotated to drive the box cover 3 to block the box body 2;
[0028] Then, the additive is put into the induction furnace 1. The specific method is to press the push plate 4 toward the direction of the box body 2 to drive the push plate 4 to move horizontally. The horizontal movement of the push plate 4 drives the connecting rod 5 to move horizontally. The horizontal movement of the connecting rod 5 drives the extrusion plate 13 to move horizontally. When the extrusion plate 13 moves horizontally, the spring 14 is squeezed. When the extrusion plate 13 moves horizontally, it also drives the sealing plate 12 and the heat insulation plate 11 to move horizontally into the slot 16. When the sealing plate 12 and the heat insulation plate 11 move horizontally into the slot 16, the upper surface of the sealing plate 12 contacts the scraper 15. On the one hand, the scraper 15 pushes the additive into the induction furnace 1, and on the other hand, it cleans the upper surface of the sealing plate 12 to prevent the additive from entering the slot 16, so as to prevent the sealing plate 12 and the heat insulation plate 11 from being unable to engage and enter the slot 16. Then, it pauses for a few seconds. When the additive enters the induction furnace 1, the push plate 4 is released. Under the rebound effect of the spring 14, the heat insulation plate 11 and the sealing plate 12 re-seal the induction furnace 1.
[0029] By configuring the box body 2, the box cover 3, the sealing plate 12 and the heat insulation plate 11, when adding additives into the induction furnace 1, the induction furnace 1 is always sealed, thereby minimizing the heat loss inside the induction furnace 1, which is beneficial to improving thermal efficiency and reducing unit energy consumption.
