DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Please refer to Figures 1-5 As shown in the figure, a rotary furnace for aluminum ash calcination treatment, including furnace body 1, the top of furnace body 1 installs motor, the bottom of furnace body 1 is hinged with support frame 3, the front end of furnace body 1 is sealed with sealed cover 2;

[0026] The inside of furnace body 1 is slidably connected with screening frame 208, the front surface of screening frame 208 is rotatably connected with multiple fan-shaped screening plates 207, the fan-shaped screening plate 207 is fan-shaped structure, the outer wall of screening frame 208 is slidably connected with sliding block 212 through sliding groove II 209, the end of sliding block 212 is connected with spring 2121 between the inner side wall of sliding groove II 209, the outside of furnace body 1 is sleeved with gear ring 205, the top of sliding block 212 is fixedly connected with the surface of gear ring 205 through connecting rod 210;

[0027] The gear ring 205 is engaged with a gear 211 which is fixed on the driving end of a motor. The outer wall of the furnace body 1 is fixed with a fixed seat 203, and the motor is fixed on the surface of the fixed seat 203. The motor drives the gear 211 to rotate and engage with the gear ring 205 to drive the screening frame 208 to rotate and screen the aluminum ash impurities in the interior.

[0028] A cylinder is fixed on the surface of the fixed seat 203, and a moving rod 202 is fixed on the driving end of the cylinder. The bottom of one end of the moving rod 202 is hingedly connected with a hinged block 201. The top of the fixed seat 203 is fixed with a limiting block 204 which penetrates through the top of the moving rod 202 to limit the moving rod 202. The bottom of the hinged block 201 is fixed with a sealing cover 2. The outer wall of the sealing cover 2 is provided with a plurality of sliding grooves I 206 corresponding in number to the connecting rods 210. The sealing cover 2 is slidably sleeved on the end surface of the furnace body 1 through the sliding grooves I 206. A circular block 4 is clamped at the middle position of the fan-shaped screening plate 207. The end of the circular block 4 and the position inside the furnace body 1 are fixedly installed on the inner wall of the furnace body 1 through a fixing rod 404. The end of the screening frame 208 is elastically embedded with rotatable balls 213.

[0029] The outer wall of the circular block 4 is provided with a plurality of clamping grooves corresponding in number to the fan-shaped screening plates 207. The position close to the clamping grooves at the bottom of the fan-shaped screening plate 207 is fixed with a clamping block 402 which is located in the clamping groove and in contact with the clamping groove. The balls 213 are located between the end of the screening frame 208 and the fan-shaped screening plate 207. The end surface of the circular block 4 is rotatably provided with a rotating block 401. The outer wall of the rotating block 401 is fixed with a plurality of rotating rods 403. The end of the rotating rod 403 is fixed with a blocking block 405 which is located on the end surface of the circular block 4 to close or open the clamping grooves.

[0030] When the aluminum ash slag inside is calcined and poured and discharged, the cylinder can be started to push the moving rod 202 to move towards the direction of the gear ring 205, and at the same time, the sealing cover 2 can be opened to the discharge port at the end of the furnace body 1. Then, the sealing cover 2 is turned up through the hinge between the hinged block 201 and the moving rod 202 to completely open the discharge port at the end of the furnace body 1. Then, the gear 211 is driven by the motor to rotate and engage with the gear ring 205. The gear ring 205 rotates to drive the screening frame 208 to rotate through the connecting rod 210 to screen the discharged materials, so as to avoid the mixed ash slag inside from affecting the use of the materials in the later period.

[0031] In the above principle, when screening materials, each fan-shaped screening plate 207 needs to be flipped to make the clamping block 402 clamped into the clamping groove of the circular block 4. In the initial state, the stop block 405 is in contact with the gap of the clamping groove to block the gap, so as to avoid that the fan-shaped screening plate 207 is completely opened due to too heavy material during screening, thereby affecting the screening effect. After the material screening is completed, the rotating block 401 is rotated to make the stop block 405 open the gap of the clamping groove, and then the impurities screened in the fan-shaped screening plate 207 are discharged, so as to avoid that the unqualified materials are always mixed with the later entering materials and cannot be completely removed. Through the setting of the spring 2121, when the sealing cover 2 opens the discharge port, the surface of the fan-shaped screening plate 207 loses the extrusion force, and the deformation expansion of the spring 2121 directly pushes the fan-shaped screening plate 207 to move outward to expand the screening area and the screening capacity of the materials, so that the material screening can be quickly completed.

[0032] Through the setting of the ball 213, the ball 213 is elastically embedded in the end of the fan-shaped screening plate 207. When the fan-shaped screening plate 207 is flipped, the edge thereof is in contact with the ball 213 to push the ball 213 to move into the end of the furnace body 1. When the fan-shaped screening plate 207 is flipped, the ball 213 is popped out to contact and close the edge of the fan-shaped screening plate 207, so as to block the materials in the screening frame 208 and the fan-shaped screening plate 207, thereby avoiding material leakage during screening. At the same time, when the fan-shaped screening plate 207 is flipped, the ball 213 is driven to rotate by the friction force, so as to reduce the abrasion and avoid jamming during flipping.

[0033] It should be noted that the fan-shaped screening plate 207 can be flipped. When the materials are put in, the fan-shaped screening plate 207 can be flipped to the inside of the furnace body 1 to open the discharge port thereof and put in the materials.
