[0019] The utility model will be further explained in detail below in combination with specific embodiments.

[0020] The flotation device, as shown in Figure 1 , comprises an existing flotation tank 1 and a conveyor belt 2. Aluminum material is floated out of the flotation tank 1 and is conveyed forward on the upper layer 21 of the conveyor belt 2 to the front end and then falls forward to a collection position for collection. The collection position is provided with an aluminum mixture collection box 50 corresponding to the front end of the conveyor belt 2. Residual aluminum material adheres to the surface of the conveyor belt 2 and is turned over to the lower layer 22 of the conveyor belt 2 and then is conveyed backward. As shown in Figure 2 , a baffle 3 and a brush 4 are arranged below the lower layer 22 of the conveyor belt 2. The brush 4 is arranged behind the baffle 3 and directly contacts the lower layer 22 of the conveyor belt 2. In the residual aluminum material, thick aluminum material is blocked by the baffle 3 and falls into a thick aluminum material collection box 51 corresponding to the front of the baffle 3. Thin aluminum material passes through the gap 23 between the baffle 3 and the lower layer 22 of the conveyor belt 2 and is brushed by the brush 4 to fall off the lower layer 22 of the conveyor belt 2 under the driving of the motor 41. The aluminum material collection boxes 50, 51 and 52 are provided with collection openings on the top surface. The baffle 3 extends downward through the collection opening of the thick aluminum material collection box 51 into the thick aluminum material collection box 51 and the back surface of the baffle 3 is attached to the rear wall of the collection opening to block the thin aluminum material brushed by the brush 4 behind the thick aluminum material collection box 51 so that the thin aluminum material falls into a thin aluminum material collection box 52 corresponding to the front of the brush 4. The residual aluminum material on the conveyor belt is thus cleaned.

[0021] As shown in Figure 2 , Figure 3 , the left and right sides of the conveyor belt 2 are respectively fixed on left and right support frames 61 and 62. The roller shaft 40 is detachably arranged between the left and right support frames 61 and 62. The brush 4 is detachably sleeved on the roller shaft 40. The motor 41 is fixed on the left support frame 61. The motor 41 drives the brush 4 by driving the roller shaft 40 to rotate. The left and right support frames 61 and 62 are respectively provided with lateral mounting holes 620. The left end of the roller shaft 40 passes through the mounting hole 620 of the right support frame 62 from the right side to the left side, enters between the left and right support frames 61 and 62, then passes through the center hole of the brush 4 so that the brush 4 is sleeved on the roller shaft 40, and continues to pass through the mounting hole 620 of the left support frame 61 to the left side to connect the motor 41. In this state, the left and right ends of the roller shaft 40 are respectively supported at the mounting holes 620 of the left and right support frames 61 and 62. The roller shaft 40 is detachably arranged between the left and right support frames 61 and 62 in this way and is driven by the motor 41 to rotate to drive the brush 4 to rotate. As shown in Figure 4The roller shaft 40 is locked on the left and right support frames 61, 62 by means of the roller shaft locking nut 431 and the roller shaft locking bolt 432.

[0022] When the old brush 4 needs to be replaced, the staff:

[0023] First, stand under the lower layer 22 of the conveyor belt 2, unscrew the roller shaft locking nut 431 and pull out the roller shaft locking bolt 432. Then hold the brush 4, and let the left end of the roller shaft 40 move away from the mounting hole 620 of the left support frame 61 to the right, and then continue to move to the left until it passes through the mounting hole 620 of the right support frame 62 to the right, thereby disassembling the roller shaft 40 from between the left and right support frames 61, 62. During this process: the old brush 4 is larger than the mounting hole 620 and cannot pass through the mounting hole 620 laterally, so the old brush 4 is blocked by the right support frame 62 and separated from the roller shaft 40, so that the old brush 4 is disassembled from between the left and right support frames 61, 62. After disassembling the old brush 4, the staff installs a new brush. The installation of the new brush is the same as that of the old brush 4, and is not described here.

[0024] The left support frame 61 and the right support frame 62 are provided with an emergency stop button 7, and the two emergency stop buttons 7 are symmetrically arranged Figure 4 The emergency stop button 7 is arranged on the right support frame 62), and is specifically arranged below the lower layer of the conveyor belt 2 and between the brush 4 and the baffle 3. The emergency stop button 7 is connected with a controller (not shown in the figure), and the controller controls the connection of the conveyor belt 2 and the motor 41. When the staff replaces the brush 4, if the motor 41 of the conveyor belt 2 or the brush 4 is mistakenly touched by an unrelated person to start operation, the emergency stop button 7 can be pressed to command the controller to perform emergency shutdown on the conveyor belt 2 and the motor 41. A material blocking cover 71 is arranged above the emergency stop button 7 to block the aluminum material falling from the conveyor belt 2, so as to prevent the aluminum material from mistakenly touching the emergency stop button 7.

[0025] As shown in Figure 2 , Figure 3 , the support rod 30 is detachably cross-mounted between the left and right support frames 61, 62, and the baffle 3 is detachably sleeved on the support rod 30. As shown in Figure 4 , the rod ends 301 at both ends of the support rod 30 are square, and the left and right support frames 61, 62 are respectively and correspondingly each provided with a square hole 621. The left end of the support rod 30 passes through the square hole 621 on the left support frame 61 from the right to the left, and then enters between the left and right support frames 61, 62, and then passes through the center hole of the baffle 3 to allow the baffle 3 to be sleeved on the support rod 30, and then continues to pass through the square hole 621 on the right support frame 62 to the left. In this state, the left and right rod ends 301 of the support rod 30 are respectively embedded in the square holes 621 of the left and right support frames 61, 62, and the support rod 30 is detachably mounted between the left and right support frames 61, 62 in this way. As shown in Figure 5The left and right ends of the support rod 30 are fixed on the left and right support frames 61, 62 respectively by means of the support rod locking nuts 311 and the support rod locking bolts 312.

[0026] When the old baffle 3 needs to be replaced, the staff:

[0027] First, the support rod locking nuts 311 at the two ends of the support rod 30 are unscrewed, and the support rod locking bolts 312 are pulled out. Then the left end of the support rod 30 is made to move to the right to disengage from the square hole 621 of the left support frame 61, and then continue to move to the left until it passes through the square hole 621 of the right support frame 62 to the right, thereby disassembling the support rod 30 from between the left and right support frames 61, 62. During this process, the baffle 3 is larger than the square hole 621 and cannot pass through the square hole 621 laterally, so the baffle 3 is separated from the support rod 30 due to being blocked by the right support frame 62. In this way, the old baffle 3 is disassembled from between the left and right support frames 61, 62. After disassembling the old baffle 3, the staff installs a new baffle. The installation operation of the new baffle is the same as that of the old baffle 3, and is not described again.
