Technical Field

[0001] The utility model relates to the technical field of furnace charge presetting equipment, in particular to a furnace charge presetting equipment for high-carbon ferrochrome smelting. Background Art

[0002] Ferrochromium is the most important raw material for stainless steel production. 200 series stainless steel contains approximately 16% chromium, 300 series stainless steel contains approximately 25%, and 400 series stainless steel contains approximately 14%. 300 series stainless steel, which has the highest demand for ferrochromium, also accounts for the largest proportion of stainless steel production. This is because chromium plays a decisive role in stainless steel. There is only one element that determines the properties of stainless steel, and each type of stainless steel contains a certain amount of chromium.

[0003] The existing production process usually involves crushing the metal raw materials, screening them, weighing them, and then putting them into a mixing tank in proportion for mixing and then smelting. This process is very cumbersome and affects work efficiency. At the same time, the existing mixing tank cannot mix the metal powder well, which affects subsequent smelting.

[0004] In view of the existing technical problems, a high-carbon ferrochrome smelting charge presetting device is needed to solve the above problems. Utility Model Content

A first motor 3 is fixedly connected to the left side of the crushing box 2, and the driving end of the first motor 3 is fixedly connected to the left side of the front crushing roller 5. A tube chain conveyor 6 is provided on the left side of the crushing box 2, and a mixing tank 1 is fixedly connected to the left side of the bottom of the crushing box 2.

A discharge pipe is provided at the bottom end of the mixing tank 1. Two contraction plates 10 are provided on the inner wall of the chute, and the adjacent sides of the two contraction plates 10 are fixedly connected to the bottom and top sides of the filter screen 8;

[0032] Specifically, during operation, metal raw materials are placed into the crushing box 2, and the first motor 3 is started to rotate the crushing roller 5. The crushing roller 5 causes the other crushing roller 5 to rotate through the linkage gear 12 to crush the raw materials. After the crushing, the raw material powder falls onto the filter screen 8. When the linkage gear 12 rotates, the reciprocating gear 14 rotates through the transmission pulley 9 and the drive pulley 11. The reciprocating gear 14 rotates and engages with the reciprocating block 15, driving the reciprocating block 15 to slide back and forth.

[0033] Example 2:

[0034] refer to Figure 1-Figure 5The bottom side of the outer wall of the discharge pipe 7 is fixedly connected to the top side of the mixing tank 1, the inner wall of the mixing tank 1 is rotatably connected to the driving stirring rod 16, the top of the outer wall of the driving stirring rod 16 is fixedly connected to a rotating plate 21, the left and right sides of the bottom of the rotating plate 21 are rotatably connected to the self-rotating driving rod 17, the top of the driving stirring rod 16 is fixedly connected to a driving gear 20, the top of the self-rotating driving rod 17 is fixedly connected to the self-rotating gear 19, the outer wall of the self-rotating gear 19 is meshed with the outer wall of the driving gear 20, so that the self-rotating driving rod 17 can also rotate while rotating around the driving stirring rod 16, and the top of the mixing tank 1 is fixedly connected to a second motor 4, and the driving end of the second motor 4 is fixedly connected to the top of the driving stirring rod 16.

[0035] Specifically, the second motor 4 is started to rotate the driving stirring rod 16. The driving stirring rod 16 rotates, driving the rotating plate 21 and the self-rotating driving rod 17 to rotate around the driving stirring rod 16 to stir the raw materials. As the self-rotating driving rod 17 rotates around the driving stirring rod 16, the driving gear 20 engages with the self-rotating gear 19, driving the two self-rotating driving rods 17 to rotate, so that the raw materials are continuously stirred inside the crushing box 2. At the same time, the scraper plate 18 scrapes the wall of the mixing tank 1 to prevent the raw materials from adhering to the inner wall of the mixing tank 1. After mixing, the raw materials are discharged from the discharge pipe.

[0036] Working Principle: During operation, metal raw material is placed into the crushing chamber 2. The first motor 3 is activated to rotate the crushing roller 5. This, in turn, rotates the other crushing roller 5 via the linkage gear 12, thereby crushing the raw material. The crushed raw material powder falls onto the filter screen 8. As the linkage gear 12 rotates, the reciprocating gear 14 rotates via the drive pulley 9 and the drive pulley 11. The reciprocating gear 14 rotates and engages with the reciprocating block 15, driving the reciprocating block 15 to slide back and forth, causing the connecting block 13 to slide back and forth. As the connecting block 13 reciprocates, the filter screen 8 slides back and forth within the chute to screen the raw material. Qualified metal powder falls through the discharge port 7 into the mixing tank 1 for mixing. Unqualified metal powder, vibrated by the filter screen 8, rolls onto the tube chain conveyor 6, where it is transported to the crushing chamber 2 for further crushing. The second motor 4 is activated to rotate the driving agitator 16. This rotation drives the rotating plate 21 and the self-rotating driving rod 17 to rotate around the driving agitator 16, stirring the raw material. As the self-rotating driving rod 17 rotates around the driving stirring rod 16, the driving gear 20 engages with the self-rotating gear 19 to drive the two self-rotating driving rods 17 to rotate, so that the raw materials are continuously stirred inside the crushing box 2. At the same time, the scraper plate 18 scrapes the wall of the mixing tank 1 to prevent the raw materials from adhering to the inner wall of the mixing tank 1. After mixing is completed, the raw materials are discharged from the discharge pipe.
