Specific embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a spodumene acid roasting rotary kiln as shown in Figures 1-4 The rotary kiln includes a rotary kiln main body 100 and a feeding mechanism 200 for feeding spodumene into the inner cavity of the rotary kiln main body 100. The feeding mechanism 200 includes a feeding hopper 201, a feeding pipe 202, and a support plate 204. The feeding pipe 202 is movably inserted through the front of the rotary kiln main body 100. The feeding hopper 201 is fixedly arranged at the top of the feeding pipe 202. The feeding hopper 201 and the feeding pipe 202 are used for feeding spodumene into the inner cavity of the rotary kiln main body 100. The support plate 204 is fixedly arranged at the end of the feeding pipe 202 away from the rotary kiln main body 100, and the support plate 204 is used for supporting the feeding pipe 202 and the feeding hopper 201 at the front position of the rotary kiln main body 100. The feeding mechanism 200 further includes a feeding rod 203 and a motor 205. The feeding rod 203 is movably arranged in the inner cavity of the feeding pipe 202 through the motor 205. The motor 205 is fixedly arranged on the end face of the support plate 204 away from the feeding pipe 202, and the output shaft of the motor 205 is in transmission connection with one end of the feeding rod 203.

[0024] Specifically refer to the figure and Figure 2, the end of the feeding pipe 202 away from the support plate 204 is movably inserted into the interior of the rotary kiln body 100 and passes through the front of the rotary kiln body 100. The feeding pipe 202 is communicated with the feeding hopper 201. The spodumene is fed from the top of the feeding hopper 201. When the feeding hopper 201 is not in use, the top is sealed with an end cover, which is beneficial to ensuring the cleanliness of the inner cavity of the feeding hopper 201 and the feeding pipe 202. When in use, the feeding space of the feeding hopper 201 is exposed by opening the end cover. The spodumene enters the inner cavity of the feeding pipe 202 through the feeding hopper 201. The motor 205 is started in advance, so that the motor 205 drives the feeding rod 203 to rotate. The feeding rod 203 is a spiral rod body, and while rotating, it can drive the spodumene in the feeding pipe 202 to move, so as to be able to send the spodumene into the inner cavity of the rotary kiln body 100. The motor 205 is electrically connected to the external power supply through an external control switch. Above, through the setting of the feeding mechanism 200, it is more convenient for the spodumene to enter the inner cavity of the rotary kiln body 100, and it can feed in an orderly manner. At the same time, it can feed spodumene of different sizes, effectively improving the processing efficiency of the spodumene through the rotary kiln body 100.

[0025] A blanking mechanism 300 is arranged inside the feeding mechanism 200. The blanking mechanism 300 includes a guiding plate 301, a plurality of blanking plates 303 and a fixing plate 304. The guiding plate 301 is fixedly arranged inside the feeding mechanism 200. A rotating roller 302 is movably arranged below the guiding plate 301. A plurality of blanking plates 303 are fixedly arranged at equal intervals on the outer wall of the rotating roller 302. The plurality of blanking plates 303 drive the rotation of the rotating roller 302 through the impact of the spodumene. The fixing plate 304 is embedded between the plurality of blanking plates 303. The fixing plate 304 is used for restricting the position of the blanking plates 303. The number of the guiding plates 301 is two. The guiding plates 301 are symmetrically and fixedly arranged in an inclined shape on the inner wall of the feeding hopper 201. The end of the blanking plate 303 away from the rotating roller 302 is arc-shaped.

[0026] For specific reference Figure 2 and Figure 4, the guide plate 301 is arranged in an inclined shape, so that the feeding direction of spodumene fed from the top of the feeding hopper 201 is guided, so that spodumene can smoothly fall onto the feeding plate 303 and the rotating roller 302 below the guide plate 301. Under the impact of the falling force of spodumene, the feeding plate 303 will be forced to rotate, so that the feeding of spodumene can be carried out along with the rotation of the feeding plate 303, thereby improving the orderliness and uniformity of spodumene feeding. Moreover, the end of the feeding plate 303 facing away from the rotating roller 302 can also stir the spodumene between the guide plates 301, which can avoid the blockage of spodumene between the guide plates 301, ensure the effectiveness of spodumene feeding, and at the same time enhance the processing effect and quality of the rotary kiln main body 100 on spodumene. The arc-shaped setting of the end of the feeding plate 303 is convenient for reducing the damage caused by collision with spodumene when being impacted by spodumene, and improves the safety of using the feeding plate 303.

[0027] A connecting mechanism 400 for restricting the position of the feeding plate 303 is arranged between the feeding plate 303 and the rotating roller 302. The connecting mechanism 400 includes a connecting groove 401 and a positioning rod 402. The connecting groove 401 is opened on the outer wall of the rotating roller 302. The connecting groove 401 is used for the feeding plate 303 to penetrate through the rotating roller 302. The positioning rod 402 is fixedly arranged on the inner wall of the connecting groove 401. The positioning rod 402 is used for strengthening the position of the feeding plate 303. Two grooves are opened on the outer wall of the feeding plate 303, and the two grooves are respectively used for the penetrating connection of the fixing plate 304 and the positioning rod 402.

[0028] For specific reference Figure 3 , the opening of the connecting groove 401 enables the feeding plate 303 to be inserted and connected with the rotating roller 302. The positioning rod 402 strengthens the stability of the connection between the feeding plate 303 and the rotating roller 302 by penetrating through the outer wall of the feeding plate 303. The two ends of the fixing plate 304 are inserted and connected with the outer wall of the adjacent feeding plate 303. And due to the extrusion of the feeding plate 303 by the fixing plate 304, the feeding plate 303 moves in the inner cavity of the connecting groove 401. After moving, the positioning rod 402 is inserted and connected with the outer wall of the feeding plate 303. Thus, the stability of the installation of the feeding plate 303 and the rotating roller 302 can be strengthened. And the fixing plate 304 is made of elastic plastic, which can squeeze the feeding plate 303 to restrict its position, and at the same time is convenient for subsequent disassembly and assembly, so that the feeding plate 303 can be disassembled, assembled and replaced separately after long-term use, effectively improving the flexibility of replacing the feeding plate 303, and further enhancing the flexibility of disassembly, assembly and use of the feeding mechanism 300.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
