Abstract
Description
TECHNICAL FIELD
[0001] The application relates to the technical field of sand mills, in particular to a dynamic discharging device of a sand mill. BACKGROUND
[0002] In the current market of grinding equipment, conventional equipment and low-end equipment generally adopt a traditional discharging and separating structure. Such equipment usually relies on large grinding media for material grinding, because the large-size grinding media are more likely to achieve preliminary material grinding and separation in terms of physical properties and movement trajectories.
[0003] However, this design has obvious defects: first, the large-size grinding media need to be frequently screened and replaced, which not only increases the operation complexity, but also increases the operation cost; second, due to the large size of the grinding media, the wear speed is fast, and the worn media often cannot be used, resulting in resource waste; third, the use of large grinding media limits the improvement of grinding efficiency, increases the operation time of the equipment, and further increases the energy consumption and labor cost. CONTENT OF THE UTILITY MODEL
[0004] In order to solve the problem that conventional equipment generally adopts a traditional discharging and separating structure and usually relies on large grinding media for material grinding, the application provides a dynamic discharging device of a sand mill.

[0006] The dynamic discharging device of the sand mill comprises a grinding cavity for material grinding, the inner side of the grinding cavity is provided with a grinding disc, the outer side of the grinding disc is provided with a discharging dynamic ring, the outer side of the discharging dynamic ring is provided with a discharging static ring, one end of the grinding disc close to the discharging dynamic ring is provided with a separating screen, and the outer side of the separating screen is provided with a centrifugal wheel.
[0007] Preferably, a gap is reserved between the discharging dynamic ring and the discharging static ring, a discharging port is arranged on the grinding cavity, and the discharging port is in communication with the gap.
[0008] Preferably, a feeding port is arranged on the grinding cavity away from the separating screen.
[0009] In summary, the application has the following beneficial technical effects:
[0010] The cooperation of the grinding disc, centrifugal wheel, separation screen, discharge dynamic ring and discharge static ring is used to separate the grinding medium and grinding material by the vortex centrifugal force generated by the rotation of the centrifugal wheel, and the further separation of the mixture is realized by the small separation gap between the discharge dynamic ring and the discharge static ring, without using large-size grinding medium, reducing the frequent screening and replacement of the grinding medium, prolonging the service life of the grinding medium, saving the use cost, improving the grinding efficiency of small grinding medium, reducing the equipment operation time, saving labor and energy consumption, avoiding the damage caused by the wear of the grinding medium into the separation gap, and reducing the maintenance cost.

[0013] The following will be described in detail in combination with the accompanying Figure 1 The application is further described in detail.
[0014] The embodiment of the application discloses a dynamic discharge device of a sand mill. Figure 1 A dynamic discharge device of a sand mill comprises a separation screen 1, a centrifugal wheel 2, a discharge dynamic ring 3, a discharge static ring 4, a grinding disc 5 and a grinding cavity 6. The grinding cavity 6 is a main area for grinding, the grinding disc 5 is installed on the inner side of the grinding cavity 6 and is used for material grinding, and the grinding medium is circulated back to the grinding area under the action of the separation screen 1.
[0015] The discharge dynamic ring 3 is installed on the grinding disc 5, the discharge static ring 4 is located on the grinding cavity 6, and the separation gap is formed by cooperation, so that the flow direction of the grinding material and a small amount of grinding medium mixture is controlled.
[0016] The separation screen 1 is detachably installed on the grinding disc 5, such as being installed by bolts, is located on the outer side of the grinding disc 5 close to one end of the discharge dynamic ring 3, is used for separating the grinding material and the grinding medium, and makes the grinding material flow to the discharge port.
[0017] The grinding cavity 6 is detachably installed on the grinding disc 5, such as being installed by bolts, is sleeved on the outer side of the separation screen 1, generates vortex centrifugal force when rotating, and realizes the separation of the grinding medium and the grinding material.
[0018] The feed port 7 is arranged on one end of the grinding cavity 6 away from the discharge dynamic ring 3 and is used for the entry of the grinding material and the grinding medium.
[0019] The discharge port 8 is communicated with the separation gap, and the discharge of the grinding material is realized through the gap between the separation screen and the discharge dynamic ring and the discharge static ring.
[0020] The implementation principle of the dynamic discharge device of the sand mill is as follows: the grinding material enters the grinding cavity 6 from the feeding port, and flows to the centrifugal wheel 2 through the grinding disc 5 area together with the grinding medium, the centrifugal wheel 2 generates vortex centrifugal force when rotating to separate the grinding medium and the grinding material, the grinding medium is pushed to the grinding disc 5 area by the action of the centrifugal wheel 2, and the grinding material flows to the discharge port along the separation screen 1, and a part of the mixture of the grinding medium and the grinding material flows to the separation gap between the discharge dynamic ring 3 and the discharge static ring 4, since the separation gap is very small, the grinding material in the mixture of the grinding medium and the grinding material flows to the discharge port along the separation gap, and the grinding medium cannot be discharged due to the large volume, and is pushed to the grinding disc 5 area by the rotation of the centrifugal wheel 2.
