[0032] Reference Figures 1 to 5 This utility model discloses a vibratory grinding device, including: a base frame 100, a grinding disc 200 and a vibratory motor 300.

[0033] Reference Figure 1 and Figure 4The grinding disc 200 is mounted on the base frame 100. The grinding disc 200 includes a first grinding body 210 and a second grinding body 220. The second grinding body 220 is disposed within the first grinding body 210. A grinding space 230 is defined between the first grinding body 210 and the second grinding body 220. The grinding space 230 is used to load powder and grinding media. The base frame 100 is used to provide support for this vibratory grinding device. The grinding disc 200 includes a first grinding body 210 and a second grinding body 220, and a grinding space 230 is defined between the first grinding body 210 and the second grinding body 220. The grinding space 230 is used to load powder and grinding media. The grinding disc 200 is used to transmit vibration to the grinding space 230, so that the powder in the grinding space 230 is ground by vibration. The grinding space 230 is used to carry the powder.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The output end of the vibration motor 300 abuts against the lower end of the first grinding body 210. The vibration motor 300 is used to vibrate the grinding disc 200 so that the powder in the grinding disc 200 is ground by the grinding medium. The output shaft of the vibration motor 300 abuts against the lower side of the grinding disc 200. The vibration motor 300 is used to provide vibration force.

[0035] In some embodiments, refer to Figure 1 , Figure 2 and Figure 5 The grinding media is grinding balls 231, and several grinding balls 231 are set. The grinding balls 231 move at high speed under vibration and directly impact the powder particles, causing them to break and plastically deform, thus achieving the initial crushing of coarse particles. The rolling and sliding between the grinding balls 231 and with the container wall generate shear force, which can further peel off the particle surface or refine the broken particles. It can be understood that the grinding balls 231 can also play a role in improving grinding efficiency and uniform grinding.

[0036] In some embodiments, refer to Figure 1 and Figure 5 The inner side of the first grinding body 210 is provided with grinding protrusions 211. The grinding protrusions 211 are used to cooperate with the grinding media to promote grinding. The setting of the grinding protrusions 211 can effectively enhance the dynamic interaction between the powder and the grinding media. The concave and convex structure formed by the grinding protrusions 211 disrupts the movement trajectory of the powder and the grinding balls 231, avoids stratification or dead corners caused by laminar flow, and promotes uniform dispersion of the powder. The blocking effect of the grinding protrusions 211 slows down the downward speed of the powder and increases the collision frequency and duration of the powder with the grinding balls 231. It is understood that a rotating arm can also be set above the grinding space 230 and inserted into the powder to assist in promoting the dispersion of the powder and increasing the collision frequency between the grinding balls 231 and the powder.

[0037] In some embodiments, refer to Figure 1 and Figures 3 to 5 It also includes a water inlet device, which includes a water storage tank 400 and a water supply pipe 410. The water storage tank 400 is located on either side of the grinding disc 200. One end of the water supply pipe 410 is connected to the water storage tank 400, and the other end of the water supply pipe 410 is used to inject water into the grinding space 230. The water supply pipe 410 is used to transport the water in the water storage tank 400 to the grinding space 230. The water storage tank 400 and the water supply pipe 410 work together to transport water to the grinding space 230. In wet grinding, water needs to be added to the mixture of powder and grinding balls 231. Water molecules form a lubricating film between the grinding balls 231 and the powder, reducing direct friction loss during dry grinding. For example, the wear rate of alumina balls can be reduced by 30%. At the same time, it buffers violent collisions and avoids the degeneration of powder caused by local overheating, such as oxidation of metal powder.

[0038] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 A shut-off valve 411 is installed on the water supply pipe 410. The shut-off valve 411 is used to control the connection or disconnection of water in the water supply pipe 410. The shut-off valve 411 is a conventional setting in this field and will not be described in detail.

[0039] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 The first grinding body 210 is provided with a discharge pipe 500. One end of the discharge pipe 500 is connected to the grinding space 230, and the other end of the discharge pipe 500 is connected to the outside. The discharge pipe 500 is used to discharge the powder and grinding balls 231 after grinding from the grinding space 230. It can be understood that the discharge pipe 500 and the water supply pipe 410 should be symmetrically arranged along the central axis of the grinding disc 200. During the discharge, water can be sprayed through the water supply pipe 410 to promote the discharge.

[0040] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 A baffle 510 is slidably inserted into the discharge pipe 500. A baffle 510 socket is provided above the discharge pipe 500. The baffle 510 is inserted into the discharge pipe 500 through the baffle 510 socket. The baffle 510 is used to control the discharge and cut-off of powder. During grinding, the baffle 510 is inserted downward to close the discharge pipe 500. During discharge, the baffle is pulled out, the discharge pipe 500 is opened, and the grinding space 230 is connected to the outside. The powder and grinding balls 231 are discharged from the grinding space 230 together. It is understood that a sealing component should be provided at the edge of the baffle 510 to prevent the powder from leaking out of the grinding space 230 during vibration grinding. The sealing component is generally made of rubber or silicone.

[0041] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 A baffle 510 is slidably inserted into the discharge pipe 500, and a baffle inlet 520 is provided above the discharge pipe 500. The baffle 510 is inserted into the discharge pipe 500 through the baffle inlet 520. The baffle 510 is used to control the discharge and cut-off of powder.

[0042] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 The device also includes a receiving box 600, which is located below the discharge pipe 500. The receiving box 600 is used to receive the powder output from the discharge pipe 500. The receiving box 600 can be placed on the ground.

[0043] In some embodiments, refer to Figure 1 , Figure 2 and Figure 5 The receiving box 600 is equipped with a filter screen 610. The filter screen 610 is used to pass the powder and retain the grinding balls 231 on the filter screen 610. The filter screen 610 is used to separate the grinding balls 231 from the ground powder. The powder is placed under the filter screen 610, and the grinding balls 231 are retained on the filter screen 610. The filter screen 610 is a conventional setting in this field and will not be described in detail.

[0044] In some embodiments, refer to Figure 1 , Figure 3 and Figure 4 The base frame 100 includes four support legs 110. The four support legs 110 are evenly arranged along the outer circumference of the base frame 100. The even arrangement of the support legs 110 along the outer circumference of the first grinding body 210 makes the base frame 100 more stable. It is understood that the number of support legs 110 can also be set to other numbers, at least three, and the other number of support legs 110 are evenly arranged along the outer circumference of the first grinding body 210.
