Abstract
Description
TECHNICAL FIELD
[0001] The application relates to the technical field of grinding machines, in particular to a grinding disc structure for a grinding machine. BACKGROUND
[0002] Traditional grinding disc structures of grinding machines are mostly designed in a conventional disc type. In this design, a transmission shaft drives the grinding disc to rotate, and the feed liquid enters the grinding area through a feed inlet for grinding. Although this design can realize the grinding of the feed liquid to a certain extent, the traditional grinding disc often lacks effective feed liquid guiding and backflow mechanisms, which leads to uneven distribution of the feed liquid in the grinding cavity. This uneven distribution not only reduces the grinding efficiency, but also may cause local over-grinding or under-grinding, affecting the quality of the final product, and because the grinding medium is easily pushed by the feed liquid during the grinding process, it is easy to concentrate and rush to the discharge outlet, causing the discharge outlet to be blocked, increasing the pressure in the cavity, and increasing the temperature of the feed liquid, thereby accelerating the wear of the discharge part and affecting the long-term stable operation of the equipment. CONTENT OF THE UTILITY MODEL

[0016] The following will be described in detail in combination with the accompanying Figures 1-2 The application is further described in detail.
[0017] The application embodiment discloses a grinding disc structure for a grinding machine. Figure 1 A grinding disc structure for a grinding machine, comprising a housing 1, a cavity 9 is installed on the inner side of the housing 1, and a transmission shaft 2 is rotatably installed on the inner side of the cavity 9. One end of the transmission shaft 2 penetrates through the housing 1 and is connected with a power input, and a mechanical sealing mechanism is installed between the transmission shaft 2 and the housing 1, for ensuring the sealing property of the connection.
[0018] Referring to Figure 1 The other end of the transmission shaft 2 is detachably installed with a pearl stirring wheel 3, and the inner side of the pearl stirring wheel 3 is installed with a separation screen 6. A discharge port 8 is installed on the housing 1 away from the pearl stirring wheel 3, and a feed port 7 is also installed on the housing 1, which is located on the inner side of the separation screen 6. The liquid is added into the cavity 9 through the discharge port 8, and the ground liquid is discharged through the feed port 7. The installation of the pearl stirring wheel 3 enables the grinding media to be pushed outwards when subjected to force, while the liquid is pushed to the separation screen 6 and flows out from the feed port 7. The separation screen 6 effectively prevents the outflow of the grinding media, ensuring the purity of the liquid after grinding.
[0019] Referring to Figure 2A plurality of grinding discs 4 are sleeved on the transmission shaft 2, the grinding disc 4 comprises a disc body 401 with a shaft hole 402 in the center, the disc body 401 is provided with four backflow holes 403, and the backflow holes 403 have a certain angle; the design enables the grinding disc 4 to generate directional force when rotating, and guides the liquid to move regularly in the cavity 9; meanwhile, the backflow holes 403 optimize the flow path of the liquid, and improve the uniformity of grinding.
[0020] With reference to Figure 1 A shaft sleeve 5 is arranged between the adjacent two disc bodies 401, and whether the adjacent two disc bodies 401 are circumferentially dislocated or not can be set according to requirements.
[0021] The implementation principle of the grinding disc structure of the grinding machine is as follows: the cavity 9 is filled with a certain proportion of grinding medium, when the transmission shaft 2 rotates, the liquid enters the cavity 9 from the discharge port 8, is subjected to thrust force, and is subjected to high-efficiency grinding and shearing crushing along the high-energy area between the grinding disc 4 and the inner wall of the cavity 9, and moves regularly to the pearl pushing wheel 3; when passing through the pearl pushing wheel 3, the grinding medium is pushed outwards along the force of the pearl pushing wheel 3, and the liquid is pushed to the separation screen 6 to flow out from the inlet 7; meanwhile, part of the liquid that is not well ground is mixed with the grinding medium, is pushed out along the shaft sleeve 5 to the direction of the discharge port 8 under the action of the backflow hole 403 on the grinding disc 4, and reaches the discharge port 8 and flows into the liquid along the grinding disc 4 and the high-energy area between the inner wall of the cavity 9, is subjected to high-efficiency grinding and shearing crushing, so that the liquid is sufficiently ground in the cavity 9, and the ground liquid is very uniform.
