[0023] See also Figure 1-4 The utility model provides an alumina powder raw material homogenizing tank, which is used to homogenize the alumina powder raw material. Compared with the prior art, it can automatically feed the material quantitatively without manual observation and confirmation. Technical solution:

[0024] An alumina powder raw material homogenizing tank comprises a homogenizing tank body 1 and a feeding part, the upper surface of the feeding part is fixedly connected with a top cover 2, the upper surface of the top cover 2 is rotatably connected with a rotating column 3, the upper surface of the rotating column 3 is provided with a plurality of quantitative openings 4 penetrating the bottom of the rotating column 3, the upper surface of the top cover 2 is provided with a feeding port 5 connected with the feeding part, and the quantitative opening 4 can quantitatively feed the raw material into the feeding part.

[0025] Specifically, a rotating column 3 is provided at the same time, and the rotating column 3 rotates so that several metering ports 4 correspond to the discharge pipe 8 in sequence, and at the same time, several metering ports 4 correspond to the feeding port 5 in sequence, so that after the metering ports 4 are filled with raw materials, they are put into the loading part through the feeding port 5. It is only necessary to set the number of revolutions of the motor 20 to control the required amount of raw materials to be put into the loading part, and no manual observation and confirmation is required. The number of metering ports 4 is at least two. In the illustrated embodiment, the number of metering ports 4 is four. At the same time, the number of metering ports 4 can also be any value not less than two.

[0026] It also includes a storage box 6, in which a screw feeder 7 is arranged, and a feed pipe 8 is fixedly connected to the surface of the screw feeder 7. The feed pipe 8 corresponds to one of the metering ports 4, and the inner diameter of the feed pipe 8 is equal to the inner diameter of the metering port 4. By arranging the storage box 6 and the screw feeder 7, the raw materials are fed into the metering port 4 through the feed pipe 8. By making the inner diameter of the feed pipe 8 equal to the inner diameter of the metering port 4, the feed pipe 8 can be used to smooth the raw materials in the metering port 4 when the rotating column 3 rotates, thereby improving the accuracy of the metering.

[0027] A rotating hole is provided on the lower surface of the top cover 2, and a rotating shaft 9 is rotatably connected to the inner wall of the rotating hole. The top end of the rotating shaft 9 is fixedly connected to the lower surface of the rotating column 3, and the bottom end of the rotating shaft 9 is fixedly connected to a driven gear 10. The lower surface of the top cover 2 is rotatably connected to a driving gear 11, and the driving gear 11 is meshed with the driven gear 10. The lower surface of the top cover 2 is fixedly connected to a frame 19, and the lower surface of the frame 19 is fixedly connected to a motor 20. The output end of the motor 20 is fixedly connected to the lower surface of the driving gear 11, and the driving gear 11 is driven to rotate by the output end of the motor 20, thereby driving the driven gear 10 to rotate, thereby driving the rotating shaft 9 to rotate, and thereby driving the rotating column 3 to rotate.

[0028] The driving gear 11 is a residual gear, and several metering ports 4 are evenly arranged in a circular array on the rotating column 3. The angle of the driving gear 11 is equal to the angle of the center lines of two adjacent metering ports 4. The driving gear 11 can make several metering ports 4 correspond to the feeding port 5 in sequence. By arranging the driving gear 11 with a residual gear, it can intermittently drive the driven gear 10 to rotate, and then drive the rotating shaft 9 to rotate, and then drive the rotating column 3 to rotate, so that several metering ports 4 correspond to the discharge pipe 8 in sequence, and at the same time, make several metering ports 4 correspond to the feeding port 5 in sequence. In the illustrated embodiment, the residual gear is a quarter gear.

[0029] A first material retaining ring 12 is fixedly connected to the upper surface of the rotating column 3, and a second material retaining ring 13 is fixedly connected to the upper surface of the top cover 2. The first material retaining ring 12 and the second material retaining ring 13 are provided to prevent the raw materials from leaking out.

[0030] The feeding part includes a feeding barrel 14, the upper surface of which is fixedly connected to the top cover 2, a feeding pipe 15 is fixedly connected to the bottom of the feeding barrel 14, the feeding pipe 15 is communicated with the homogenizing tank body 1, and a first supporting leg 16 is fixedly connected to the bottom of the feeding barrel 14. By arranging the feeding barrel 14 and the feeding pipe 15 to cooperate, the raw materials are fed into the homogenizing tank body 1.

[0031] A discharge pipe 17 is fixedly connected to the bottom of the homogenizing tank body 1 , a valve is provided on the surface of the discharge pipe 17 , and a second supporting leg 18 is fixedly connected to the bottom of the homogenizing tank body 1 .

[0032] Working principle: When the alumina powder raw material homogenizing tank is used, the user first starts the homogenizing tank body 1, and starts the screw feeder 7 to feed the raw material in the storage box 6 into the corresponding quantitative port 4 through the feed pipe 8. When the quantitative port 4 is full, the material cannot be transported further, and the motor 20 is started at the same time. The output end of the motor 20 drives the driving gear 11 to rotate, and the driving gear 11 intermittently drives the driven gear 10 to rotate, and the driven gear 10 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the rotating column 3 to rotate, and the rotating column 3 moves the quantitative port 4 to the next position, and at the same time the next quantitative port 4 is moved to the next position. The metering port 4 is moved to a position corresponding to the feeding pipe 8 for loading. During the movement, the feeding pipe 8 smoothes the raw materials in the metering port 4 to improve the quantitative accuracy. At the same time, the upper surface of the rotating column 3 fits with the bottom end of the feeding pipe 8, so that the raw materials are not easy to leak out. In this way, the materials are loaded in sequence until the first metering port 4 filled with raw materials moves to the position corresponding to the feeding port 5. The raw materials in the metering port 4 enter the loading barrel 14 through the feeding port 5, and then enter the homogenizing tank body 1 through the feeding pipe 15. The homogenizing tank body 1 homogenizes it, so that the alumina powder raw material homogenizing tank has a quantitative feeding effect.
