Description

Technical Field

[0001] The utility model relates to the technical field of magnetic powder recovery, in particular to a magnetic powder recovery device. Background Art

[0002] In the process of producing paper for RMB, enterprises inevitably produce some waste paper, which contains metal wires. In order to recycle these waste papers, manufacturers usually crush the waste paper and mix it with water for re-production. Since the waste paper contains metal wires, the mixed liquid contains more magnetic powder, which needs to be removed from the liquid to improve the production quality of the paper. The production equipment commonly used by enterprises needs to absorb and remove magnetic powder in the middle section of the process. The conventional absorption process uses manual placement of strong magnetic rods in a certain section in the middle for fixed-point removal. Due to the limitations of this process, the waiting time for manual intervention is long, and the internal slurry is not uniform, resulting in unsatisfactory removal effect. This process is dependent on the staff to regularly remove the magnetic powder adsorbed by the strong magnetic rods at fixed points, which indirectly affects the work efficiency of other processes.

[0003] Therefore, an enterprise has proposed a device for removing magnetic powder. The specific content of the device is recorded in the Chinese patent document with publication number CN220460976U. The device includes a water tank, a liquid inlet and a liquid outlet are provided on the side wall of the water tank, a partition is provided inside the water tank, and a liquid passage slot is provided on the partition. The liquid in the water tank passes through the partition and is discharged from the water tank through the liquid outlet. A through hole is provided on the top wall of the water tank at a position corresponding to the liquid passage slot, and an electromagnetic rod is provided in the through hole. One end of the electromagnetic rod is located in the liquid passage slot with a gap between the electromagnetic rod and the liquid passage slot, and the other end extends to the top of the water tank. The electromagnetic rod is consistent with the length direction of the liquid passage slot. A driving member and an abutment member are provided above the water tank. The driving member is used to drive multiple electromagnetic rods to move along the length direction of the liquid passage slot, and the abutment member is used to surround and fit the outer wall of the electromagnetic rod when the electromagnetic rod moves from top to bottom. The abutment member includes a plurality of clamping components, and the clamping components include a first clamping block, a second clamping block, a first telescopic member, and a second telescopic member arranged on the top wall of the water tank. The first clamping block is located on one side of the electromagnetic rod, and the first telescopic member is used to drive the first clamping block to approach or move away from the electromagnetic rod. The second clamping block is located on the side of the electromagnetic rod away from the first clamping block, and the second telescopic member is used to drive the second clamping block to approach or move away from the electromagnetic rod. The first clamping block and the second clamping block are provided with a notch on one side close to the electromagnetic rod, and when the first clamping block and the second clamping block are respectively pressed against the electromagnetic rod, the side surfaces of the first clamping block and the second clamping block facing each other are pressed against each other, and the peripheral side of the electromagnetic rod is pressed against the inner side of the two notches. The scheme is to absorb the magnetic powder in the solution by the electromagnetic rod, and then drive the electromagnetic rod to move up by the driving member. When the electromagnetic rod moves up to the top, the clamping component clamps the lower end of the electromagnetic rod, and at this time, the driving member drives the electromagnetic rod to descend, so that the clamping component can achieve the effect of scraping the magnetic powder on the surface of the electromagnetic rod.

[0004] The specification of the above document states that: a high-pressure nozzle is installed in the storage box, the high-pressure nozzle is connected to a high-pressure water pipe, the high-pressure water pipe is in turn connected to a water pump and a clean water tank, a drain pipe is connected to the side wall of the water tank, the drain pipe extends to the outside of the shell, and the drain pipe is connected to a sewage tank. When the electromagnetic rod descends to the specified position, the water pump uses the clean water in the clean water tank to flush the magnetic powder in the storage box through the high-pressure nozzle, so as to facilitate the discharge of the magnetic powder in the storage box through the drain pipe to the outside of the shell.

[0005] Regarding the above-mentioned related technologies, the applicant believes that the above-mentioned scheme is to flush and recover the magnetic powder in the storage box by high-pressure clean water. Although the magnetic powder in the storage box can be taken out to the sewage tank outside the shell, it is easy to waste a lot of water resources. Utility Model Content

[0006] The utility model aims to provide a magnetic powder recovery device to solve the problem of easy waste of water resources when recovering magnetic powder in the related art.

[0007] The utility model is realized by the following technical solutions:

[0008] A magnetic powder recovery device comprises a magnetic powder removal device body, the magnetic powder removal device body comprises a water tank and an electromagnetic rod, a storage box is arranged above the water tank, the electromagnetic rod is lifted and lowered on the water tank and the storage box, a clamping assembly is arranged in the storage box, the clamping assembly comprises a first clamping block, a second clamping block and a telescopic member, the telescopic member is used to drive the first clamping block and the second clamping block to clamp the outer wall of the electromagnetic rod, a first opening mask is arranged above the first clamping block, a second opening mask is arranged above the second clamping block, the side walls of the first opening mask and the second opening mask that are directly opposite to each other are both opened, and the top walls of the first opening mask and the second opening mask are both in contact with the inner top wall of the storage box, when the first clamping block and the second clamping block clamp the outer wall of the electromagnetic rod, the first opening mask and the second opening mask are docked to form a closed structure, the closed structure is connected with a compressed air pipe and a discharge pipe, and the discharge pipe is connected with a collection box.

[0009] Furthermore, a pressure sensor is provided on the outer top wall of the storage box, and the pressure sensor is electrically connected to a controller.

[0010] Furthermore, the top wall of the material collecting box is provided with an exhaust hole.

[0011] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0012] In the utility model, the magnetic powder contained in the water tank is adsorbed by the electromagnetic rod, and then the electromagnetic rod is driven to rise by the driving member. When the electromagnetic rod rises to the specified position, the telescopic member drives the first clamping block and the second clamping block to clamp the outer wall of the electromagnetic rod. At this time, the first opening mask and the second opening mask also move relatively to each other and form a closed structure. When the driving member drives the electromagnetic rod to descend, the first clamping block and the second clamping block scrape the magnetic powder adsorbed on the surface of the electromagnetic rod into the closed structure. At this time, high-pressure air is transported into the closed structure through the compressed air pipe. The high-pressure air can purge the magnetic powder inside the closed structure, so that the magnetic powder in the closed structure is transported to the collection box through the discharge pipe for temporary storage, which is convenient for the subsequent recovery of the magnetic powder. Since the closed structure is smaller than the storage box, the high-pressure air can effectively purge the inside of the closed structure, which is convenient for improving the efficiency of cleaning the magnetic powder and reducing the waste of water resources.

[0020] Example 1

[0021] A magnetic powder recovery device, referring to Figure 1 , Figure 2, including a magnetic powder removing device body, the magnetic powder removing device body includes a water tank 1 and an electromagnetic rod 2, a storage box 3 is arranged above the water tank 1, the electromagnetic rod 2 is lifted and arranged on the water tank 1 and the storage box 3, a clamping assembly is arranged in the storage box 3, the clamping assembly includes a first clamping block 4, a second clamping block 5 and a telescopic member, the telescopic member is used to drive the first clamping block 4 and the second clamping block 5 to clamp the outer wall of the electromagnetic rod 2, a first opening mask 6 is arranged above the first clamping block 4, a second opening mask 7 is arranged above the second clamping block 5, the side walls of the first opening mask 6 and the second opening mask 7 that are opposite to each other are both opened, and the top walls of the first opening mask 6 and the second opening mask 7 are both in contact with the inner top wall of the storage box 3, when the first clamping block 4 and the second clamping block 5 clamp the outer wall of the electromagnetic rod 2, the first opening mask 6 and the second opening mask 7 are docked to form a closed structure, the closed structure is connected with a compressed air pipe 8 and a discharge pipe 9, and the discharge pipe 9 is connected with a collecting box 10. The electromagnetic rod 2 is used to adsorb the magnetic powder contained in the water tank 1, and then the electromagnetic rod 2 is driven to rise by the driving member. When the electromagnetic rod 2 rises to the specified position, the first clamping block 4 and the second clamping block 5 are driven by the telescopic member to clamp the outer wall of the electromagnetic rod 2. At this time, the first opening mask 6 and the second opening mask 7 also move relative to each other and form a closed structure. When the driving member drives the electromagnetic rod 2 to descend, the first clamping block 4 and the second clamping block 5 scrape the magnetic powder adsorbed on the surface of the electromagnetic rod 2 into the closed structure. At this time, high-pressure air is transported into the closed structure through the compressed air pipe 8. The high-pressure air can purge the magnetic powder inside the closed structure, so that the magnetic powder in the closed structure is transported to the collection box 10 through the discharge pipe 9 for temporary storage, which is convenient for subsequent recovery of the magnetic powder. Since the closed structure is smaller than the storage box 3, the high-pressure air can effectively purge the closed structure, which is convenient for improving the efficiency of cleaning the magnetic powder and reducing the waste of water resources. The specific structure of the magnetic powder removal device body can be found in the literature mentioned above, so this embodiment will not be repeated. In this embodiment, the closed structure is cylindrical.

[0022] As a preferred embodiment, refer to Figure 1 , Figure 2A pressure sensor 11 is arranged on the outer top wall of the storage box 3, and the pressure sensor 11 is electrically connected to the controller. A squeezing plate 12 is arranged at the end of the electromagnetic rod 2 extending above the storage box 3. When the electromagnetic rod 2 drops to a specified position, the squeezing plate 12 squeezes the pressure sensor 11. A solenoid valve is arranged on the compressed air pipe 8, and the solenoid valve is electrically connected to the controller. When the electromagnetic rod 2 drops to a specified position, it means that the first clamping block 4 and the second clamping block 5 have scraped the magnetic powder on the electromagnetic rod 2 to the right place. At this time, the power supply of the electromagnetic rod 2 is disconnected first, and the squeezing plate 12 squeezes the pressure sensor 11. The plate 12 squeezes the pressure sensor 11, and the pressure sensor 11 can detect a certain pressure value, such as 5N, 10N, etc. When the pressure sensor 11 detects a preset pressure value, the controller will control the solenoid valve to open, so as to automatically conduct the compressed air pipe 8, and the compressed air pipe 8 is connected to the external air storage tank, so as to automatically deliver high-pressure air to the closed structure through the compressed air pipe 8, thereby timely purging the magnetic powder inside the closed structure, and purging the magnetic powder through the discharge pipe 9 to the collection box 10 for storage. The electromagnetic valve, air storage tank and controller are not shown in the drawings of this embodiment.

[0023] As a preferred embodiment, refer to Figure 1 , Figure 2 An exhaust hole 13 is provided on the top wall of the collecting box 10, so that the magnetic powder recovery device can more smoothly transport high-pressure air along the compressed air pipe 8, the closed structure, the discharge pipe 9 and the collecting box 10, thereby achieving high-efficiency recovery of magnetic powder.

[0024] It should be noted that the magnetic powder is light in weight and can be moved by high-pressure air in a small space; in addition, according to actual needs, the compressed air pipe 8 and the discharge pipe 9 used in this solution are made of a material with a certain softness, such as a rubber tube, at least in the pipe section close to the closed structure, to facilitate the movement of the compressed air pipe 8 and the discharge pipe 9 with the first opening mask 6 and the second opening mask 7.
