[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a magnetic powder recovery system for magnetic coagulation sedimentation, including a magnetic powder recovery box 1, a pretreatment tank 11 is provided at the top of the magnetic powder recovery box 1 near the left side, a flushing tank 12 is provided at the top of the magnetic powder recovery box 1 near the right side, a first magnetic adsorption cylinder 2 is provided between the inner walls of the pretreatment tank 11, a second magnetic adsorption cylinder 21 is provided between the inner walls of the first magnetic adsorption cylinder 2, the second magnetic adsorption cylinder 21 and the two ends of the rotating shaft 22 are fixedly installed with a rotating shaft 22, the outer surfaces of the plurality of rotating shafts 22 respectively slide through the inner walls of the pretreatment tank 11 and the flushing tank 12 and extend to the outside, wherein gears 31 are fixedly installed on the end faces of two rotating shafts 22, a toothed belt 32 is meshed between the outer surfaces of the two gears 31, a bracket 16 is fixedly installed on the front surface of the magnetic powder recovery box 1, a motor 3 is fixedly installed on the top of the bracket 16, the output end of the motor 3 is fixedly connected to the end face of one of the gears 31, and the magnetic powder is recovered by the magnetic recovery box 1. A first guide aluminum plate 23 is fixedly installed at the middle position of the top of the recovery box 1, and the left surface of the first guide aluminum plate 23 is in contact with the outer wall of the first magnetic adsorption tube 2; a second guide aluminum plate 24 is fixedly installed at the right edge of the top of the magnetic powder recovery box 1, and the left surface of the second guide aluminum plate 24 is in contact with the outer wall of the second magnetic adsorption tube 21; a mounting plate 6 is fixedly installed on the left surface of the magnetic powder recovery box 1; a mud inlet pipe 61 is fixedly installed on the outer surface of the mounting plate 6 near the inner top; the outer surface of the mud inlet pipe 61 passes through the outer surface of the mounting plate 6 and extends to the other side; a buffer tank 62 is fixedly installed on the right surface of the mounting plate 6 below the mud inlet pipe 61; a mounting frame 4 is fixedly installed on the outer surface of the magnetic powder recovery box 1 near the right side; a water pipe 41 is fixedly installed on the top of the mounting frame 4; the outer surface of the water pipe 41 passes through the top of the mounting frame 4 and extends to the bottom; a sprinkler 42 is fixedly installed on the bottom end of the water pipe 41.

[0024] The effect achieved by the entire embodiment 1 is that the sludge enters the buffer tank 62 through the sludge inlet pipe 61. When the sludge in the buffer tank 62 is full, it overflows from the low position on the right and falls on the surface of the left half of the first magnetic adsorption cylinder 2. Since the sludge overflows from the edge of the buffer tank 62, it avoids the problem of uneven distribution caused by the sludge being too concentrated when discharged from the sludge inlet pipe 61, thereby improving the sludge treatment effect. The high-strength magnetism of the first magnetic adsorption cylinder 2 itself makes the magnetic powder in the sludge or fluid adsorbed on its surface. The first magnetic adsorption cylinder 2 can be driven to rotate by starting the motor 3, so that the magnetic powder adsorbed on the first magnetic adsorption cylinder 2 can be transported to the right. When the magnetic powder moves to the position of the first guide aluminum plate 23, the first guide aluminum plate 23 is in contact with the surface of the first magnetic adsorption cylinder 2, so that the magnetic powder can be peeled off from the first magnetic adsorption cylinder 2, and the magnetic powder slides downward on the surface of the first guide aluminum plate 23. When it slides to the low position of the first guide aluminum plate 23, it passes through the second magnetic adsorption cylinder 21 The high strength of the motor 3 can adsorb the magnetic powder on its surface. When the motor 3 drives the gear 31 on the left to rotate, the two gears 31 can rotate synchronously with the cooperation of the toothed belt 32, that is, the first magnetic adsorption cylinder 2 and the second magnetic adsorption cylinder 21 can rotate synchronously through the rotating shaft 22. When the second magnetic adsorption cylinder 21 rotates, the magnetic powder can continue to be transported to the right. After the external water source is connected through the water pipe 41, the water source can enter the sprayer 42 through the water pipe 41 and spray the surface of the left half of the second magnetic adsorption cylinder 21, so that the sludge remaining on the surface of the magnetic powder can be washed, and the separation effect is improved. The washed sewage flows into the washing tank 12 through the gap between the second magnetic adsorption cylinder 21 and the first guide aluminum plate 23. In the process of separating the magnetic powder, the continuous rotation of the first magnetic adsorption cylinder 2 and the second magnetic adsorption cylinder 21 can achieve the effect of continuous recovery of magnetic powder, avoiding the need to divide the sludge into multiple times and pour it into the device for processing when a large amount of sludge is processed, thereby improving work efficiency.

[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the inner bottoms of the pretreatment tank 11 and the rinsing tank 12 are penetrated with through holes 13, a sewage hopper 15 is fixedly installed near the middle of the bottom of the magnetic powder recovery box 1, and the sewage hopper 15 is connected to the two through holes 13, and the bottom of the magnetic powder recovery box 1 is fixed with legs 14 near the four corners, so a collecting box 5 is arranged on the right side of the magnetic powder recovery box 1, and universal wheels 51 are fixedly installed at the bottom of the collecting box 5 near the four corners, and a handle 52 is fixedly installed on the right surface of the collecting box 5.

[0026] The effect achieved by the entire embodiment 2 is that, by setting the through hole 13, the sludge or sewage that is not magnetic on the surface of the first magnetic adsorption cylinder 2 and the second magnetic adsorption cylinder 21 can be guided to the sewage hopper 15 and discharged, thereby achieving the sewage discharge effect. By setting the collecting box 5, it is convenient to collect the separated magnetic powder, and by setting a universal wheel 51 with a self-locking device at the bottom thereof, combined with the handle 52, it is convenient to move or replace at any time, thereby improving work efficiency.

[0027] Working principle: During operation, the sludge enters the buffer tank 62 through the sludge inlet pipe 61. When the sludge in the buffer tank 62 is full, it overflows from the low position on the right side and falls on the surface of the left half of the first magnetic adsorption cylinder 2. The first magnetic adsorption cylinder 2 has a high magnetic strength, so that the magnetic powder in the sludge or fluid is adsorbed on its surface, and the non-magnetic sludge flows into the pretreatment tank 11, and then flows through the through hole 13 at the bottom to the sewage hopper 15 and is discharged, so that the magnetic powder can be initially separated. By starting the motor 3, The first magnetic adsorption cylinder 2 is driven to rotate, so that the magnetic powder adsorbed on the first magnetic adsorption cylinder 2 can be transported to the right. When the magnetic powder moves to the position of the first guide aluminum plate 23, the first guide aluminum plate 23 is in contact with the surface of the first magnetic adsorption cylinder 2, so that the magnetic powder can be peeled off from the first magnetic adsorption cylinder 2, and the magnetic powder slides down on the surface of the first guide aluminum plate 23. When it slides to the lower position of the first guide aluminum plate 23, the second magnetic adsorption cylinder 21 has its own high strength to adsorb the magnetic powder on its surface. When the motor 3 is driven When the gear 31 on the left side rotates, the two gears 31 can be rotated synchronously with the cooperation of the toothed belt 32, that is, the first magnetic adsorption cylinder 2 and the second magnetic adsorption cylinder 21 can be rotated synchronously through the rotating shaft 22. When the second magnetic adsorption cylinder 21 rotates, the magnetic powder can be continuously transported to the right. After the external water source is connected through the water pipe 41, the water source can enter the sprayer 42 through the water pipe 41 and spray the surface of the left half of the second magnetic adsorption cylinder 21, so that the sludge remaining on the surface of the magnetic powder can be washed, thereby improving the separation. The flushed sewage flows into the flushing trough 12 through the gap between the second magnetic adsorption cylinder 21 and the first guide aluminum plate 23, and then flows into the sewage bucket 15 through the through hole 13 at the bottom and is discharged. When the magnetic powder moves to the position of the second guide aluminum plate 24, the second guide aluminum plate 24 fits with the surface of the second magnetic adsorption cylinder 21, so that the magnetic powder can be peeled off from the second magnetic adsorption cylinder 21, and the magnetic powder slides down on the surface of the first guide aluminum plate 23 and falls into the collection box 5, thereby completing the recovery of the magnetic powder.
