An air outlet pipe 5 is arranged at the upper end of the mounting seat 302. The quick-release filtering mechanism 3 further includes a concave groove 306, a sliding port 307, a locking port 308 and a locking block 309. The concave grooves 306 are evenly arranged at the upper end of the mounting cylinder 301. Sliding ports 307 are arranged at the right ends of the concave grooves 306. Locking blocks 309 are fixedly connected to the lower ends of the inner walls of the mounting seats 302. The locking blocks 309 are all slidably connected with the laterally adjacent concave grooves 306. Locking ports 308 are arranged at the left ends of the concave grooves 306. The locking blocks 309 are all clamped with the laterally adjacent locking ports 308. The quick-release filtering mechanism 3 further includes a support ring 303 and a spring 305. The springs 305 are evenly fixedly connected to the bottom wall of the mounting groove 304. The upper ends of the springs 305 are all fixedly connected to the lower end of the support ring 303. The support ring 303 is slidably connected inside the mounting groove 304. The upper surface of the support ring 303 is in contact with the lower surface of the mounting seat 302. The quick-release filtering mechanism 3 further includes a driving handle 311. The driving handle 311 is fixedly connected to the center position of the lower surface of the filter net 310. When the filter net 310 is used to a certain extent, first press down the mounting seat 302. The mounting seat 302 moves downward to push the support ring 303 to slide downward inside the mounting groove 304, thereby causing the springs 305 to be elastically compressed. At the same time, when the mounting seat 302 moves downward, the locking blocks 309 all end the clamping with the corresponding locking ports 308, and the locking blocks 309 all reach the bottom of the concave grooves 306.

Then rotate the filter net 310 through the driving handle 311 so that the filter net 310 moves out of the inside of the mounting seat 302, and screw a new filter net 310 into the inside of the mounting seat 302 to replace the filter net 310, and clean the replaced filter net 310. Then slide the mounting seat 302 into the mounting groove 304. The locking blocks 309 of the mounting seat 302 all enter the inside of the vertically adjacent concave grooves 306 through the corresponding sliding ports 307. At the same time, the mounting seat 302 moves downward to push the support ring 303 to slide downward inside the mounting groove 304, thereby causing the springs 305 to be elastically compressed. When the locking blocks 309 all reach the bottom of the concave grooves 306, rotate the mounting seat 302 in the opposite direction. When the locking blocks 309 all reach the lower side of the locking ports 308, stop pressing the mounting seat 302, and the elastic force of the springs 305 acts on the support ring 303.The support ring 303 pushes the mounting base 302 upward, so that the locking blocks 309 are all clamped into the vertically adjacent locking ports 308, realizing the quick installation of the filter screen 310;

[0023] Wherein: a support disk 4 is fixedly connected to the lower end of the roasting bin 1, an air inlet pipe 14 is arranged at the lower end of the roasting bin 1, the lower end of the air inlet pipe 14 is communicated with the air outlet of an external blower, a feed inlet 6 is arranged at the rear end of the roasting bin 1, uniformly distributed air inlet pipes 11 are arranged in the middle of the roasting bin 1, nozzles 12 are arranged at one ends of the air inlet pipes 11 close to the roasting bin 1, the other ends of the air inlet pipes 11 far from the center of the roasting bin 1 are communicated with the same connecting pipe 13, a burner 15 is arranged at the rear side of the roasting bin 1, the air outlet of the burner 15 is communicated with the rear end of the connecting pipe 13, and the input ends of the burner 15 and the external blower are electrically connected to the output end of the control switch group 17.

[0024] The working principle of a calcination furnace for aluminum concentrate provided by the present utility model is as follows: During operation, the personnel stably place the calcination bin 1 and the burner 15 in a horizontal working area. After the placement is stable, the personnel inject the aluminum concentrate raw material into the interior of the calcination bin 1 through the feed port 6. Then, the personnel operate the burner 15 and the external blower through the control switch group 17. The burner 15 provides flames to the interior of the calcination bin 1 through the connecting pipe 13, the intake pipe 11, and the nozzle 12 in sequence. At the same time, the external blower fills a specific gas into the interior of the calcination bin 1 through the air inlet pipe 14 to realize the calcination of the aluminum concentrate. The gas generated by the calcination rises and passes through the filtration of the filter screen 310 to filter out dust, and then is discharged through the air outlet pipe 5. When the filter screen 310 is used to a certain extent, the personnel first press down the mounting seat 302. The downward movement of the mounting seat 302 pushes the support ring 303 to slide downward inside the mounting groove 304, thereby elastically compressing the springs 305 uniformly. At the same time, the downward movement of the mounting seat 302 causes the locking blocks 309 to end the clamping connection with the corresponding locking ports 308. The locking blocks 309 reach the bottom of the concave groove 306. Then, the personnel rotate the mounting seat 302 so that the locking blocks 309 reach the lower end of the sliding port 307. Then, the personnel lift the mounting seat 302 upward, and the locking blocks 309 slide upward out of the corresponding sliding ports 307, and the mounting seat 302 is taken out. Then, the personnel rotate the filter screen 310 through the driving handle 311 so that the filter screen 310 moves out of the interior of the mounting seat 302, and a new filter screen 310 is spirally connected into the interior of the mounting seat 302 to replace the filter screen 310, and the replaced filter screen 310 is cleaned. Then, the mounting seat 302 is slid into the interior of the mounting groove 304. The locking blocks 309 of the mounting seat 302 enter the interior of the vertically adjacent concave grooves 306 through the corresponding sliding ports 307. At the same time, the downward movement of the mounting seat 302 pushes the support ring 303 to slide downward inside the mounting groove 304, thereby elastically compressing the springs 305 uniformly. When the locking blocks 309 reach the bottom of the concave grooves 306, the personnel rotate the mounting seat 302 in the reverse direction. When the locking blocks 309 reach the lower side of the locking ports 308, the personnel stop pressing the mounting seat 302. The elastic force of the springs 305 acts on the support ring 303, and the support ring 303 pushes the mounting seat 302 upward, so that the locking blocks 309 are clamped into the interior of the vertically adjacent locking ports 308, realizing the rapid installation of the filter screen 310.

[0025] It should be noted that, in the above embodiments, the control switch group 17 is provided with control buttons corresponding to the external blower and the burner 15 one by one to control their switches.
