[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0030] An embodiment of the present application provides a separation device 10, see Figure 1 、 Figure 2 and Figure 3 The separation device 10 is used to cooperate with the discharge hole 20a of the grinding cylinder 20. The grinding cylinder 20 has a grinding chamber 20b connected to the discharge hole 20a. The separation device 10 includes a supporting body 11 and an upper end plate 12.

[0031] The supporting body 11 is used to be installed at the discharge hole 20a.

[0032] The upper end plate 12 is disposed at one end of the support body 11 and encloses the support body 11 to form a separation chamber 10 a . An end of the separation chamber 10 a facing away from the upper end plate 12 is communicated with the grinding chamber 20 b .

[0033] A partial area of ​​the upper end plate 12 is penetrated to form a feed hole 12a, and the hole wall of the feed hole 12a extends toward the separation chamber 10a to form a blocking wall 121. The bottom end of the blocking wall 121 is lower than the top cavity wall of the separation chamber 10a to guide the grinding medium in the separation chamber 10a to move toward the side away from the feed hole 12a.

[0034] Specifically, the separation device 10 refers to a component disposed at the discharge hole 20 a of the grinding cylinder 20 and used to guide the grinding media separated from the grinding cylinder 20 back to the grinding cylinder 20 .

[0035] The grinding cylinder 20 refers to a component in the grinding machine for accommodating and grinding the material to be ground, and has a grinding chamber 20b inside.

[0036] The discharge hole 20 a refers to a channel through which the ground material is discharged from the grinding cylinder 20 .

[0037] The supporting body 11 is a main structural part of the separating device 10 and is used to be installed at the discharge hole 20a of the grinding cylinder 20 to play a supporting and fixing role.

[0038] The upper end plate 12 refers to a component provided at one end of the support body 11 , and the upper end plate 12 and the support body 11 together enclose a separation chamber 10 a .

[0039] The upper end plate 12 has any structural type. For example, the upper end plate 12 is a plate-shaped structure. Of course, it can also be other types of structures as long as it can be enclosed with the support body 11 to form the separation cavity 10a.

[0040] The material passage hole 12a refers to a channel that passes through the upper end plate 12 and is used for allowing the ground material to pass through and leave the separation chamber 10a.

[0041] The blocking wall 121 refers to a structure formed by the hole wall of the feed hole 12a extending into the separation chamber 10a, and is used to block the grinding medium and prevent it from passing through the feed hole 12a and entering the subsequent process.

[0042] The direction in which the hole wall of the feed hole 12a extends into the separation chamber 10a is not limited.

[0043] For example, the hole wall of the feeding hole 12a extends toward the separation chamber 10a along the height direction of the separation device 10. That is, the extending direction of the blocking wall 121 is parallel to the direction away from the upper end plate 12 to close to the upper end plate 12.

[0044] For example, the wall of the feed hole 12a extends obliquely toward the separation chamber 10a relative to the height of the separator 10. In other words, as it moves away from the upper end plate toward the upper end plate 12, the outer wall of the barrier wall 121 tilts away from the center of the feed channel 121a. This, on the one hand, expands the range of the barrier wall 121 that blocks the grinding media. On the other hand, it more effectively guides the grinding media toward the side away from the feed hole 12a, reducing the grinding media's residence time within the separation chamber 10a and improving grinding efficiency.

[0045] Specifically, the outer wall of the barrier wall 121 refers to the surface of the barrier wall 121 on the side close to the separation chamber 10 a .

[0046] The separation device 10 of the embodiment of the present application is used to cooperate with the discharge hole 20a of the grinding cylinder 20. The grinding cylinder 20 has a grinding chamber 20b connected to the discharge hole 20a. The separation device 10 includes a support body 11 and an upper end plate 12. The support body 11 is used to be installed at the discharge hole 20a. The upper end plate 12 is arranged at one end of the support body 11 and is enclosed with the support body 11 to form a separation chamber 10a. The end of the separation chamber 10a facing away from the upper end plate 12 is connected to the grinding chamber 20b. A partial area of ​​the upper end plate 12 is penetrated to form a feed hole 12a. The hole wall of the feed hole 12a extends into the separation chamber 10a to form a blocking wall 121. The bottom end of the blocking wall 121 is lower than the top cavity wall of the separation chamber 10a to guide the grinding medium in the separation chamber 10a to move toward the side away from the feed hole 12a. Thus, on the one hand, the blocking wall 121 blocks the grinding media, preventing them from escaping from the grinding chamber 20b and entering the subsequent process with the material, thereby improving the purity of the ground material. On the other hand, the blocking wall 121 can guide the grinding media that has escaped from the grinding chamber 20b through the discharge hole 20a back into the grinding chamber 20b, reducing the possibility of insufficient material grinding due to a reduction in the amount of grinding media, thereby improving grinding efficiency and the grinding effect of the material.

[0047] In one embodiment, please refer to Figure 1 and Figure 4The barrier wall 121 encloses a feed channel 121a. The end of the feed channel 121a facing away from the feed hole 12a communicates with the separation chamber 10a. The cross-sectional area of ​​at least a portion of the feed channel 121a gradually increases from away from the upper end plate 12 to closer to the upper end plate 12. This prevents the risk of material blockage caused by narrow space during flow.

[0048] Specifically, when the material enters the feed channel 121a from the feed hole 12a, the feed channel 121a becomes wider, so that the material can be dispersed in the feed channel 121a, reducing the risk of blockage, and thus allowing the ground material to be smoothly discharged from the feed channel 121a.

[0049] The material passing channel 121 a refers to a channel formed by the inner wall of the barrier wall 121 for materials to pass through.

[0050] The cross-sectional area of ​​at least a part of the transfer channel 121a gradually increases, which means that along the direction away from the upper end plate 12 to the direction close to the upper end plate 12, the cross-sectional area of ​​the entire area of ​​the transfer channel 121a gradually increases, or the cross-sectional area of ​​a part of the transfer channel 121a gradually increases.

[0051] In one embodiment, please refer to Figure 1 and Figure 4 The end of the support body 11 near the grinding cylinder 20 is partially curved, and the degree of curvature of the support body 11 is the same as the curvature of the wall of the grinding cylinder 20. This allows the support body 11 to better conform to the shape of the grinding cylinder 20, making the connection between the separation device 10 and the grinding cylinder 20 tighter and reducing the connection gap. This effectively prevents material and grinding media from leaking from the connection between the support body 11 and the grinding cylinder 20 during the grinding and separation process, thereby improving the sealing of the entire grinding system.

[0052] Specifically, the degree of curvature of the support body 11 being the same as the curvature of the wall of the grinding cylinder 20 means that the curvature of the area where the support body 11 and the grinding cylinder 20 meet and the curvature of the wall of the grinding cylinder 20 form a concentric circle. In other words, the circle defined by the arc formed by the area where the support body 11 and the grinding cylinder 20 meet and the circle defined by the arc formed by the wall of the grinding cylinder 20 are concentric circles, i.e., the radius of the circular surface defined by the area where the support body 11 and the grinding cylinder 20 meet and the radius of the circular surface defined by the grinding cylinder 20 are the same.

[0053] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3The support body 11 is partially open to form an observation port 11a that communicates with the separation chamber 10a. Thus, through the observation port 11a, the operator can intuitively observe the working conditions in the separation chamber 10a, promptly identify and address problems, thereby improving the stability and reliability of the equipment operation.

[0054] Specifically, the shape and size of the observation port 11 a are not limited, as long as the operator can visually observe the working conditions in the separation chamber 10 a through the observation port 11 a.

[0055] For example, the shape of the observation port 11 a is circular.

[0056] For another example, the shape of the observation port 11a is rectangular.

[0057] In one embodiment, a cover plate is provided at the observation port 11a and is movable relative to the observation port 11a, thereby preventing foreign matter from entering the separation chamber 10a through the observation port 11a, thereby reducing the purity of the material or affecting the stability of the equipment operation.

[0058] Specifically, the material type of the cover plate is not limited.

[0059] For example, the cover plate is made of a transparent material, thereby protecting the working environment in the separation chamber 10a and facilitating observation.

[0060] The viewing port 11 a is provided in any region of the support body 11 .

[0061] For example, the observation port faces the connection between the separation chamber 10a and the feed channel 121a, so that the connection is exposed to the outside field of view. In this way, the operator can intuitively observe the working conditions of the connection between the separation chamber 10a and the feed channel 121a, and promptly discover and deal with problems, thereby improving the stability and reliability of the equipment operation.

[0062] In one embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 The upper end plate 12 is partially recessed to form a mounting groove, and a portion of the mounting groove is penetrated to form a feed hole 12a. The mounting groove is used to install the screen. As a result, the mounting groove makes the screen installation process more convenient, allowing the screen to be installed quickly and accurately, reducing errors and difficulties during the installation process and improving the installation efficiency of the screen.

[0063] Specifically, the screen refers to a component with a filtering function. The screen can screen the ground material, allowing the qualified material to pass through and intercepting the material that does not meet the screening conditions.

[0064] In a specific embodiment, a seal is provided at the connection between the installation slot and the screen, thereby improving the sealing effect and reducing the risk of material leakage from the connection between the installation slot and the screen.

[0065] There is no limit to the connection method between the installation trough and the screen.

[0066] For example, the mounting trough and the screen are connected by fasteners.

[0067] For another example, the mounting slot and the screen mesh are connected by snap-fit.

[0068] In one embodiment, please refer to Figure 1 and Figure 3 The wall of the feed hole 12a extends into the mounting groove to enclose the wall of the mounting groove to form a fixing groove 12b, which is used to fix the screen. This can make the connection between the screen and the separation device 10 more stable and prevent the screen from shifting and shaking during operation of the device.

[0069] Specifically, the fixing groove 12b refers to the space formed by the hole wall of the feeding hole 12a extending into the installation groove and enclosed by the wall of the installation groove, which is used to firmly fix the screen to ensure the stable position of the screen during operation.

[0070] In one embodiment, please refer to Figure 4 and Figure 5 The top wall of the separation chamber 10a is arc-shaped, thereby preventing the grinding media and the materials that have not left the material passage 121a from forming a dead corner or piling up at the top of the separation chamber 10a, thereby reducing the agglomeration of the materials.

[0071] Specifically, the arc angle of the top wall of the separation chamber 10a is not limited, as long as the grinding media and the materials that have not left the material passage 121a can be returned to the grinding chamber 20b.

[0072] Another embodiment of the present application provides a grinding machine. Figure 4 and Figure 5 , including the separation device 10 of any of the above-described embodiments, the separation device 10 is located on top of the grinding cylinder 20. This allows the grinding media blocked by the barrier wall 121 to return to the grinding chamber 20b under the guidance of the barrier wall 121 and the action of its own gravity, thereby improving grinding efficiency. It also reduces the impact force of the material during discharge, thereby extending the service life of the equipment.

[0073] Specifically, the separation device 10 is located at the top of the grinding cylinder 20, which means that the extension direction of the grinding cylinder 20 is horizontal, and the separation device 10 is located on the cylinder wall at the top of the grinding cylinder 20. In other words, the discharging mode of the grinder is a top discharging mode.

[0074] In the description of this application, the descriptions with reference to the terms "in one embodiment", "in some embodiments", "in a specific embodiment", or "exemplary" etc. mean that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application.
