[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] During actual use, since titanium dioxide and magnetic impurities are mixed together, when the thickness of the accumulated titanium dioxide is too high, the demagnetization effect of the titanium dioxide is reduced, and it is necessary for the staff to perform demagnetization multiple times, reducing the work efficiency.

[0021] In view of this, the present invention provides a demagnetization device for titanium dioxide production, which solves the problem that during actual use, since titanium dioxide and magnetic impurities are mixed together, when the thickness of the accumulated titanium dioxide is too high, the demagnetization effect of the titanium dioxide is reduced, and it is necessary for the staff to perform demagnetization multiple times, reducing the work efficiency.

[0022] Through those skilled in the art, the components in this case are connected in sequence. For the specific connection and operation sequence, reference should be made to the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process.

[0023] Example 1: Consisting of Figures 1-5It can be known that a demagnetization device for titanium dioxide production includes a box body 1. A fixed frame 11 is fixedly connected to the bottom of the box body 1. A discharge port 12 is opened on one side of the box body 1. A magnetic attraction rod 13 is arranged above the box body 1. The demagnetization device for titanium dioxide production further includes a circulation device 2, a sealing device 3 and a flipping device 4. The auger 21 of the circulation device 2 extends into the box body 1; the sealing device 3 is attached to one side of the discharge port 12; the flipping device 4 is fixedly connected to the top of the magnetic attraction rod 13; wherein, the titanium dioxide in the box body 1 is agitated by the circulation device 2, the discharge port 12 on one side of the box body 1 is sealed by the sealing device 3, and the flipping device 4 facilitates the cleaning of the magnetic attraction rod 13. The magnetic attraction rod 13 utilizes the strong magnetic field generated by the permanent magnetic material to adsorb the magnetic impurities in the titanium dioxide on the surface of the magnet, so as to achieve the purpose of demagnetization;

[0024] In the specific implementation process, it is particularly worth noting that when cleaning the magnetic substances in the titanium dioxide, an appropriate amount of water body is mixed with the titanium dioxide, and the mixed titanium dioxide and water are placed in the box body 1. Under the action of the circulation device 2, the titanium dioxide and the water body are agitated, and the magnetic substances in the water body and the titanium dioxide are adsorbed by the cooperation of the magnetic attraction rod 13. Moreover, the flipping device 4 facilitates the cleaning of the magnetic attraction rod 13, and by opening the sealing device 3 on the discharge port 12, the demagnetized titanium dioxide is discharged;

[0025] Further, the circulation device 2 includes an auger 21, a first servo motor 22, a conveying pipe 23 and a guide plate 24. The auger 21 is arranged inside the box body 1; the output end of the first servo motor 22 is fixedly connected to one end of the auger 21; the conveying pipe 23 is rotationally connected to the outer wall of the auger 21 through a sealing bearing, and is fixedly connected to the outer wall of the first servo motor 22 and the inner wall of the box body 1; the guide plate 24 is arranged on one side of the discharge port of the conveying pipe 23 and is fixedly connected to the upper part of the inner wall of the box body 1; wherein, through the cooperation of the auger 21 and the first servo motor 22, the auger 21 rotates inside the conveying pipe 23, and the guide plate 24 makes the distance between the titanium dioxide and the magnetic attraction rod 13 closer;

[0026] In the specific implementation process, it is particularly worth noting that a collection shell is installed at the bottom of the conveying pipe 23, and the bottom width of the collection shell can fit with the inner wall width of the box body 1. In this way, when the auger 21 rotates, the titanium dioxide and the water body in the box body 1 are sucked into the conveying pipe 23, and the titanium dioxide and the water body are discharged through the outlet at the top of the conveying pipe 23 and fall on the guide plate 24. When moving on the guide plate 24, the magnetic substances in the titanium dioxide are agitated to the upper part, so that the magnetic attraction rod 13 can better remove the magnetic substances in the titanium dioxide. In this way, the magnetic substances in the titanium dioxide are removed. The two magnetic attraction rods 13 above the guide plate 24 are placed parallel to the guide plate 24, so that the magnetic attraction rod 13 can better adsorb the magnetic substances;

[0027] Further, the sealing device 3 includes a sealing plate 31, a pin 32 and a fixing block 33. The sealing plate 31 is rotatably connected to the outer wall of the box body 1 through a pin shaft and abuts against the inner wall of the discharge port 12; the pin 32 abuts against the outer wall of the sealing plate 31; the fixing block 33 is fixedly connected to the outer wall of the box body 1 and sleeved on the outer wall of the pin 32; wherein, through the cooperation of the fixing block 33 and the pin 32, the sealing plate 31 seals the discharge port 12.

[0028] In the specific implementation process, it is particularly pointed out that a rubber pad is fixedly connected to the side of the sealing plate 31 close to the discharge port 12, so that the sealing between the sealing plate 31 and the discharge port 12 is tighter. By inserting the pin 32 into the fixing block 33 and abutting against the outer wall of the sealing plate 31, the sealing plate 31 is fixed to the outer wall of the box body 1, and the discharge port 12 is opened.

[0029] Specifically, when using the demagnetization device for titanium dioxide production, when demagnetizing titanium dioxide, the titanium dioxide is placed in the box body 1, and appropriate water is poured into the box body 1 to mix the titanium dioxide with the water body. After placing, an external controller is used to control the first servo motor 22 to drive the auger 21 to rotate, so that the water body and titanium dioxide in the box body 1 enter the conveying pipe 23 and are discharged through the upper discharge port, falling on the deflector 24, so that the magnetic substances in the titanium dioxide are turned to the upper part, enabling the magnetic attraction rod 13 to better remove the magnetic substances in the titanium dioxide. This process is repeated to remove the magnetic substances in the titanium dioxide. By repeating this process, the magnetic substances in the titanium dioxide can be removed more thoroughly. After cleaning, the pin 32 is pulled out of the fixing block 33 to remove the blockage of the sealing plate 31, so that the sealing plate 31 can be opened from the discharge port 12, and the demagnetized titanium dioxide can be discharged. Moreover, the box body 1 is placed at an angle facing the direction of the discharge port 12, which facilitates discharging.

[0030] Embodiment 2: Consisting of Figures 1-5It can be seen that the flipping device 4 includes a mounting plate 41, a second servo motor 42, a clamping plate 43 and a limiting device 44. The mounting plate 41 is rotatably connected to the top of the magnetic attraction rod 13 through a sealing bearing and abuts against the top of the box body 1. The second servo motor 42 is fixedly connected to the top of the mounting plate 41, and the output end extends to the bottom of the mounting plate 41 and is fixedly connected to the top of the magnetic attraction rod 13. The clamping plate 43 is fixedly connected to the top of the box body 1, and the inner wall is slidably clamped to the outer wall of the mounting plate 41. The limiting device 44 is installed on the outer wall of the mounting plate 41. Among them, through the cooperation of the second servo motor 42 and the clamping plate 43, the mounting plate 41 drives the magnetic attraction rod 13 to flip, and the limiting device 44 can make the mounting plate 41 stable during installation. The model of the second servo motor 42 is not limited, as long as it meets the actual use situation, and it is connected to the same controller and external power supply as the first servo motor 22;

[0031] In the specific implementation process, it is particularly worth noting that the second servo motor 42 is used to drive the magnetic attraction rod 13 to rotate, and the rotation range of the magnetic attraction rod 13 is smaller than the width of the box body 1, so as to avoid collision with the inner wall of the box body 1. After adsorbing the magnetic substance, the mounting plate 41 is lifted upward and the mounting plate 41 is flipped to place the magnetic attraction rod 13 upward, which is more convenient for the staff to clean the impurities on the magnetic attraction rod 13;

[0032] Furthermore, the limiting device 44 includes a mounting block 441 and a clamping block 442. The mounting block 441 is fixedly connected to the outer wall of the mounting plate 41. The clamping block 442 is fixedly connected to the bottom of the mounting block 441 and is inserted into the top of the box body 1. Among them, through the cooperation of the mounting block 441 and the clamping block 442, the mounting plate 41 is stable when placed;

[0033] In the specific implementation process, it is particularly worth noting that when the mounting plate 41 is placed, the clamping block 442 is inserted into the top of the box body 1, so that the mounting plate 41 can be fixed on the top of the box body 1, which can ensure the stability of the magnetic attraction rod 13 during rotation;

[0034] Specifically, on the basis of the above embodiments, when demagnetizing titanium dioxide, the second servo motor 42 is used to drive the magnetic attraction rod 13 to rotate, so that the adsorption area of the magnetic attraction rod 13 can be increased. When cleaning the impurities on the magnetic attraction rod 13, the mounting plate 41 is lifted and flipped to place the magnetic attraction rod 13 upward, which is convenient for cleaning. On the contrary, when placing, the clamping block 442 is inserted into the top of the box body 1 to make the mounting plate 41 stable during fixation and avoid the mounting plate 41 from shaking when the magnetic attraction rod 13 rotates.
