Technical Field

[0001] The utility model relates to the technical field of forsterite processing, in particular to a device for calcining forsterite raw ore. Background Technique

[0002] Forsterite belongs to ultrabasic plutonic rock, is a common rock-forming mineral, and is also one of the earliest formed minerals during magma crystallization. It is mostly found in igneous rocks such as gabbro, basalt, and peridotite. Due to the strong resistance of forsterite to alkaline slag, its products are mostly used as checker bricks in regenerators, etc.

[0003] The processing of forsterite includes a calcination process. After calcination, forsterite calcined ore can be obtained, and after grinding, fine powder products of different particle sizes can be obtained. However, in the existing forsterite calcination process, most of them stack the forsterite raw ore in a container for calcination treatment. The container has a simple structure and does not have a mechanism for uniform heating of the forsterite raw ore, resulting in uneven heating of the forsterite, which not only increases the difficulty of forsterite calcination but also requires an extended calcination time, thus reducing the practicability of the device.

The upper surface of the main body 1 of the calcination box is respectively fixedly installed with a driving motor 5 and a feeding pre - heating assembly 6. By arranging the first calcination cavity 2, the second calcination cavity 3 and a plurality of flame nozzles 102 inside the outer box body 101, and starting a plurality of flame nozzles 102 to continuously spray flames, it is convenient to carry out the calcination operation on the periclase raw ore in the first calcination cavity 2 and the second calcination cavity 3.

[0024] The rising and heat - equalizing component 4 includes a driving shaft 401 rotatably connected to the inner top wall of the calcination box body 1 and three driven shafts 402. The output end of the driving motor 5 is fixedly connected to the upper end of the driving shaft 401. A driving gear 403 and a rising auger blade 404 are respectively installed on the shaft body of the driving shaft 401. A rising cylinder 405 is sleeved on the outer wall of the rising auger blade 404. One end of each of the three connecting rods 7 is fixedly connected to the rising cylinder 405. A driven gear 406 and a heat - equalizing rod 407 are fixedly connected to the shaft body of each of the three driven shafts 402. The three driven gears 406 are all meshed with the driving gear 403. When the driving motor 5 is started, it drives the driving shaft 401, the driving gear 403 and the rising auger blade 404 to rotate, and then drives the three driven gears 406, the three driven shafts 402 and the three groups of heat - equalizing rods 407 to rotate. The heat - equalizing rods 407 fully heat - equalize and stir the raw forsterite ore inside the first calcination chamber 2, improving the uniformity of the heat received by the raw forsterite ore. The rising auger blade 404 lifts the raw forsterite ore at the bottom of the second calcination chamber 3, transports it through the rising cylinder 405 to the upper end of the first calcination chamber 2 and exports it, making the raw forsterite ore at the original upper end move closer to the bottom of the second calcination chamber 3, completing the position exchange of the raw forsterite ore, thereby fully calcining the raw forsterite ore, achieving the purpose of shortening the calcination time and improving the practicability of the device.

[0025] The feeding and pre - heating component 6 includes a feeding and pre - heating box 601 welded on the upper surface of the calcination box body 1. A feeding pipe 602 is fixedly connected to the lower surface of the feeding and pre - heating box 601. Valves 8 are installed on the pipe bodies of the feeding pipe 602 and the discharging pipe 103. A heat - transfer pipe 603 and a protective net cylinder 604 are respectively installed inside the feeding and pre - heating box 601. The pipe bodies of the feeding pipe 602 and the heat - transfer pipe 603 both penetrate through the inner top wall of the calcination box body 1 and are connected to the inside of the first calcination chamber 2. A number of heat - outlet holes 605 are opened on the pipe body of the heat - transfer pipe 603. The protective net cylinder 604 is sleeved on the outer wall of the heat - transfer pipe 603. A sealing cover 606 is movably connected to the upper surface of the feeding and pre - heating box 601. During the calcination process, the heat generated in the calcination chamber enters the heat - transfer pipe 603 and is dissipated into the inside of the feeding and pre - heating box 601 through a number of heat - outlet holes 605, making full contact with the raw forsterite ore inside the feeding and pre - heating box 601 to achieve pre - heating, improving the thermal energy utilization rate and reducing the thermal energy consumption. By setting the protective net cylinder 604, the raw forsterite ore is prevented from blocking the heat - outlet holes 605.

[0026] Working principle: During use, through the material conveying pipe 602 on the feeding preheating box 601, the raw forsterite ore to be calcined is introduced into the first calcination chamber 2 and the second calcination chamber 3. Then, the valve 8 on the material conveying pipe 602 is closed, and the next batch of raw forsterite ore to be calcined is poured into the feeding preheating box 601. The sealing cover 606 is covered, and several flame nozzles 102 are started to continuously spray flames to perform the calcination operation on the raw forsterite ore in the first calcination chamber 2 and the second calcination chamber 3. The driving motor 5 is started to drive the rotation of the driving rotating shaft 401, the driving gear 403, and the rising auger blade 404, thereby driving the rotation of the three driven gears 406, the three driven rotating shafts 402, and the three groups of heat homogenizing rods 407. The heat homogenizing rods 407 fully homogenize and stir the raw forsterite ore inside the first calcination chamber 2 to improve the uniformity of the raw forsterite ore being heated. The rising auger blade 404 lifts the raw forsterite ore at the bottom of the second calcination chamber 3, conveys it through the rising cylinder 405 to the upper end of the first calcination chamber 2 for export, causing the raw forsterite ore originally at the upper end to move closer to the bottom of the second calcination chamber 3, completing the exchange of the position of the raw forsterite ore, thereby fully calcining the raw forsterite ore, achieving the purpose of shortening the calcination time, improving the practicability of the device. During the calcination process, the heat generated in the calcination chamber enters the heat transfer pipe 603 and is dissipated into the interior of the feeding preheating box 601 through several heat outlet holes 605, making full contact with the raw forsterite ore in the feeding preheating box 601 to achieve preheating, improving the thermal energy utilization rate, reducing the thermal energy consumption. By setting the protective net cylinder 604, it is possible to prevent the raw forsterite ore from blocking the heat outlet holes 605.
