[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0016] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of a preferred embodiment of the roasting apparatus for producing high-carbon ferrochrome provided by this utility model; Figure 2 for Figure 1 The diagram shows the internal structure of the outer cylinder. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 2 The enlarged schematic diagram of section B is shown below; Figure 5 for Figure 2 The enlarged schematic diagram of section C is shown. The calcining apparatus for high-carbon ferrochrome production includes: an outer cylinder 1, with two sets of support columns 2 fixedly installed at the bottom of the outer cylinder 1; a side door 3 is installed at the left end of the outer cylinder 1 via a hinge; a feed hopper 5 is fixedly installed on the outer wall of the side door 3; an annular plate 10 is fixedly installed between the inner walls of the left and right sides of the outer cylinder 1; an inner cylinder 4 is rotatably connected between the inner walls of the two sets of annular plates 10; several sets of circular holes are evenly opened on the side walls of the inner cylinder 4, and the left end of the inner cylinder 4 is open and in contact with the side door 3; a stirring assembly 7 is installed between the inner cylinder 4 and the outer wall of the outer cylinder 1; a linkage assembly 11 for driving the rotation of the inner cylinder 4 is installed between the stirring assembly 7 and the inner cylinder 4; an mounting plate 8 is fixedly installed between the two sets of support columns 2; a heating assembly 9 for heating the inner cylinder 4 is installed between the top of the mounting plate 8 and the inside of the outer cylinder 1; and a cooling assembly 6 for cooling the inner cylinder 4 is installed on the top of the outer cylinder 1.

[0017] The stirring assembly 7 includes a motor 71, which is fixedly installed on the outer wall of the right end of the outer cylinder 1. The output end of the motor 71 extends into the interior of the outer cylinder 1 and is rotatably connected to the side wall of the outer cylinder 1. A transmission rod 72 is fixedly installed on the output end of the motor 71. The left end of the transmission rod 72 extends into the interior of the inner cylinder 4 and is rotatably connected to the side wall of the inner cylinder 4. Several sets of stirring blades 73 are evenly fixedly installed on the outer wall of the transmission rod 72. The right end of the transmission rod 72 is connected to the linkage assembly 11.

[0018] The output end of the motor 71 drives the stirring blade 73 to stir the material inside the inner cylinder 4 through the transmission rod 72, while the linkage component 11 drives the inner cylinder 4 to rotate in the opposite direction.

[0019] The linkage assembly 11 includes a pulley 112, which is fixedly connected to the outer wall of the right end of the transmission rod 72. A shaft 114 is rotatably connected to the inner wall of the right end of the outer cylinder 1. A pulley 113 is fixedly installed on the outer wall of the shaft 114. A belt 111 is installed between the pulley 113 and the pulley 112. A gear 115 is fixedly installed on the left end of the shaft 114.

[0020] While the transmission rod 72 drives the stirring blade 73 to rotate, the pulley 112, through the linkage of the belt 111 and the pulley 113, causes the rotating shaft 114 to drive the gear 115 to rotate continuously.

[0021] A toothed ring 116 is fixedly installed on the outer wall of the right end of the inner cylinder 4, and the toothed ring 116 is meshed with the gear 115.

[0022] The rotating gear 115 continuously drives the inner cylinder 4 to rotate through the gear ring 116, and the rotation direction is opposite to that of the transmission rod 72, which helps to improve the material turning efficiency, thereby increasing the contact area with the heating component 9 and the cooling component 6.

[0023] The heating assembly 9 includes a heating box 91 and a blower 93. Both the heating box 91 and the blower 93 are fixed on the top of the mounting plate 8. The air inlet of the heating box 91 is connected to the air outlet of the blower 93. An air inlet pipe 92 is fixedly installed at the air outlet of the heating box 91.

Several sets of nozzles 94 are evenly fixedly installed on the top of the round pipe 95.

[0024] As the inner cylinder 4 rotates continuously, the material inside the cylinder will continuously tumble. At the same time, the blower 93 will send external gas into the heating box 91 for heating. Then, the hot gas will pass through the second air inlet pipe 92, through the round pipe 95, and then be sprayed out through the nozzle 94. It will enter through the round hole on the outer wall of the inner cylinder 4 to heat the material.

[0025] The cooling assembly 6 includes a cooler 61, which is fixedly installed on the outside of the outer cylinder 1. An air intake pipe 63 is fixedly installed at the air inlet of the cooler 61, and an air outlet pipe 62 is fixedly installed at the air outlet of the cooler 61. The other end of the air outlet pipe 62 extends into the inside of the outer cylinder 1.

[0026] After the material inside the inner cylinder 4 is heated, the air cooler 61 is started. The air cooler 61 will draw in the external gas through the suction pipe 63, cool it, and then send it into the outer cylinder 1 through the inlet pipe 62.

[0027] The working principle of the calcination device for high-carbon ferrochrome production provided by this utility model is as follows: The high-carbon ferrochrome to be processed is fed into the inner cylinder 4 through the feed hopper 5. Then, the stirring component 7 and the heating component 9 are started. At the same time, under the action of the linkage component 11, the stirring component 7 stirs the material inside the inner cylinder 4, and the inner cylinder 4 also rotates in the opposite direction to increase the contact area between the material and the heating component 9, thereby improving the heating efficiency. When cooling is required, the heating component 9 is turned off, and the cooling component 6 is turned on to cooperate with the stirring component 7 to accelerate the cooling of the material. Finally, the side door 3 is opened to take out the material.

[0028] Compared with related technologies, the calcination apparatus for high-carbon ferrochrome production provided by this utility model has the following beneficial effects: The output end of the motor 71 drives the stirring blade 73 to stir the material inside the inner cylinder 4 through the transmission rod 72. At the same time, the pulley 112 drives the shaft 114 to drive the gear 115 to rotate continuously through the linkage of the belt 111 and the pulley 113. The rotating gear 115 drives the inner cylinder 4 to rotate continuously through the gear ring 116. The rotation direction is opposite to that of the transmission rod 72, which helps to improve the material turning efficiency and thus increase the contact area with the heating component 9 and the cooling component 6.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
