[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] The utility model proposes a drying device for powder preparation, comprising: a base 1;

[0029] A titanium dioxide placement box 2 is fixed on the top of the base 1, and the base 1 is used to support the titanium dioxide placement box 2, and the titanium dioxide placement box 2 is used to hold the titanium dioxide that needs to be dried; the bottom of the titanium dioxide placement box 2 is provided with a drying shell 3 through integral molding, and the drying shell 3 is used to support the rotation of the drying drum 6; a discharge shell 4 is welded to the bottom of the drying shell 3, and the discharge shell 4 is used to discharge the dried titanium dioxide outward, and when the titanium dioxide slides obliquely downward in the discharge shell 4, it can also be further dried by the hot air introduced by the hot air pipe 5, thereby ensuring the drying effect; a hot air pipe 5 is provided on the top rear side of the discharge shell 4, and the hot air pipe 5 is used to introduce hot air into the discharge shell 4, so that the hot air can be evenly contacted with the titanium dioxide in the discharge shell 4, thereby further drying the titanium dioxide, and the hot air will be discharged outward through the opening on the front side of the discharge shell 4. When the hot air flows, it can also help the titanium dioxide to slide forward, so that the dried titanium dioxide can flow outward; a drying drum 6 is rotatably installed inside the drying shell 3. The drying drum 6 is used to slowly transport the titanium dioxide downward to avoid too much titanium dioxide falling at one time and affecting the drying. The drying drum 6 can also perform preliminary drying of the titanium dioxide; a total of six groups of heating wires 7 are arranged inside the drying drum 6. When in use, the heating wires 7 can all be energized and turned on. When the heating wires 7 are energized, they will heat the drying drum 6.

[0030] In the embodiment of the present disclosure, Figures 1-4As shown, the rear side of the discharge shell 4 is connected with the long strip opening at the bottom of the drying shell 3, and the discharge shell 4 is an inclined shell with a higher back and a lower front. The front side of the discharge shell 4 is also a funnel-shaped structure. During use, when the long strip groove on the outside of the drying drum 6 rotates to the bottom, the titanium dioxide inside it will fall into the discharge shell 4 through the long strip opening at the bottom of the drying shell 3 and slide obliquely downward, reducing the possibility of titanium dioxide accumulation inside the device, and the funnel-shaped structure on the front side of the discharge shell 4 also facilitates the collection of the dried titanium dioxide.

[0031] In the embodiment of the present disclosure, Figure 3 and Figure 4 As shown, a cylindrical cavity is provided inside the drying shell 3, and the inner diameter and length of the cylindrical cavity are equal to the outer diameter and length of the drying drum 6. When the elongated groove on the outside of the drying drum 6 rotates to the top, the titanium dioxide in the titanium dioxide placement box 2 will fall into the elongated groove on the outside of the drying drum 6 through the elongated opening at the top of the drying shell 3. Then the drying drum 6 continues to rotate to drive the titanium dioxide in the elongated groove on its outside to move downward. Moreover, because the outer wall of the drying drum 6 is in close contact with the inner wall of the drying shell 3, the titanium dioxide will not leak downward.

[0032] In the embodiment of the present disclosure, Figures 1-4 As shown, a rectangular tube is provided at the bottom of the hot air pipe 5, and the rectangular tube at the bottom of the hot air pipe 5 connects the cavity inside the hot air pipe 5 with the cavity inside the discharge shell 4. When in use, the hot air pipe 5 will introduce hot air into the cavity inside the discharge shell 4, so that the hot air can be evenly contacted with the titanium dioxide in the discharge shell 4, thereby further drying the titanium dioxide.

[0033] In the embodiment of the present disclosure, Figure 3 and Figure 4 As shown, the outside of the drying drum 6 is provided with a total of six long strip grooves arranged in a ring, and the top and bottom of the drying shell 3 are provided with a long strip opening, and the size of the long strip openings at the top and bottom of the drying shell 3 is equal to the size of the long strip groove on the outside of the drying drum 6. When the long strip groove on the outside of the drying drum 6 rotates to the top, the titanium dioxide in the titanium dioxide placement box 2 will fall into the long strip groove on the outside of the drying drum 6 through the long strip opening at the top of the drying shell 3, and then the drying drum 6 continues to rotate to drive the titanium dioxide in the long strip groove on the outside thereof to move downward. When the long strip groove on the outside of the drying drum 6 rotates to the bottom, the titanium dioxide inside it will fall into the discharge shell 4 through the long strip opening at the bottom of the drying shell 3.

[0034] In the embodiment of the present disclosure, Figure 5 and Figure 6As shown, the interior of the drying drum 6 is provided with six arc grooves arranged in a ring shape, and the arc grooves correspond one to one to the long strip grooves on the outside of the drying drum 6. The heating wires 7 are equidistantly arranged in the arc grooves inside the drying drum 6. When in use, the heating wires 7 can be powered on. After the heating wires 7 are powered on, they will heat the drying drum 6. When the drying drum 6 rotates, it will drive the titanium dioxide in the long strip grooves on its outside to move downward. In this process, most of the heat emitted by the heating wires 7 will be transferred to the long strip grooves on the outside of the drying drum 6, so that the titanium dioxide can be preliminarily heated and dried.

[0035] Example 2, based on Example 1, Figures 1-6 As shown, the inner walls of the front and rear sides of the bottom of the titanium dioxide placement box 2 are both inclined surfaces, and the inner wall of the bottom of the titanium dioxide placement box 2 is inclined downward toward the long strip opening at the top of the drying shell 3. When the long strip groove on the outside of the drying drum 6 rotates to the top, the titanium dioxide in the titanium dioxide placement box 2 will fall into the long strip groove on the outside of the drying drum 6 through the long strip opening on the top of the drying shell 3. Then the drying drum 6 continues to rotate to drive the titanium dioxide in the long strip groove on its outside to move downward. The inclined inner wall at the bottom of the titanium dioxide placement box 2 facilitates the falling of the titanium dioxide.

[0036] The working principle of this embodiment is as follows: when in use, the device can be placed on the ground with the support of the base 1, and then a motor can be fixed to one side of the titanium dioxide placing box 2 through a bracket, and the main shaft of the motor can be connected to one end of the drying drum 6 for transmission, so that the drying drum 6 can be driven to rotate by the motor, and then one end of the hot air pipe 5 can be connected to the external hot air blower. When the titanium dioxide needs to be dried, the titanium dioxide can be poured into the titanium dioxide placing box 2 first, and then the motor, hot air blower and heating wire 7 can be powered on. After the heating wire 7 is powered on, it will heat the drying drum 6. When the motor rotates, it will drive the drying drum 6 to rotate synchronously in the drying shell 3, and when the elongated groove on the outside of the drying drum 6 rotates to the top, the titanium dioxide in the titanium dioxide placing box 2 will fall into the elongated groove on the outside of the drying drum 6 through the elongated opening at the top of the drying shell 3, and then the drying drum 6 continues to rotate. It can drive the titanium dioxide powder in the outer elongated groove to move downward, and because the outer wall of the drying drum 6 is in close contact with the inner wall of the drying shell 3, the titanium dioxide powder will not leak downward. In this process, most of the heat emitted by the heating wire 7 will be transferred to the elongated groove on the outside of the drying drum 6, so that the titanium dioxide powder can be preliminarily heated and dried. When the elongated groove on the outside of the drying drum 6 rotates to the bottom, the titanium dioxide powder inside it will fall into the discharging shell 4 through the elongated opening at the bottom of the drying shell 3 and slide obliquely downward. At the same time, the hot air pipe 5 will introduce the hot air into the cavity inside the discharging shell 4, so that the hot air can be evenly contacted with the titanium dioxide powder in the discharging shell 4, thereby further drying the titanium dioxide powder, and the hot air will be discharged outward through the opening on the front side of the discharging shell 4. When the hot air flows, it can also assist the titanium dioxide powder to slide forward, making it convenient for the dried titanium dioxide to flow out.
