[0051] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0052] First, refer to Figure 1-Figure 21 A ball mill according to an embodiment of the second aspect of the utility model is briefly described. The ball mill includes a cylinder and an end cover 100. The cylinder is horizontally arranged and provided with a ball milling chamber. The ball milling chamber is open at one end of the cylinder axis, and the end cover 100 is arranged at the open opening. The horizontal arrangement here means that the axis of the cylinder can be parallel to the horizontal plane, and the axis of the cylinder can also have a certain angle with the horizontal plane. It can be understood that the arrangement of the cylinder in the ball mill can be adjusted according to needs when the ball mill is installed and arranged. For example, the cylinder can have a slight inclination angle with the horizontal plane to facilitate the discharge of the slurry.

[0053] Reference below Figure 1-Figure 21 An end cover 100 for a ball mill according to an embodiment of the first aspect of the present utility model is described.

[0054] like Figure 1-Figure 4As shown, the end cover 100 for a ball mill according to the embodiment of the first aspect of the utility model comprises: a cover body 10 and a feed pipe 30. The cover body 10 is provided with a feed inlet 101 and a discharge port 102; the feed pipe 30 is in communication with the ball mill chamber, one end of the feed pipe 30 is connected to the cover body 10, and the other end of the feed pipe 30 is connected to the open port of the ball mill chamber, and the feed pipe 30 is configured to be deformable so that the cover body 10 can move between a working position and a discharge position. In the working position, the cover body 10 is arranged opposite to the open port, and in the discharge position, the discharge port 102 of the cover body 10 is lower than the bottom of the ball mill chamber.

[0055] In this embodiment, a cover body 10 and a feed pipe 30 are arranged on the end cover 100, and the feed pipe 30 is connected to the ball mill chamber. Specifically, one end of the feed pipe 30 is connected to the cover body 10, and the other end of the feed pipe 30 is connected to the open port. A feed port 101 and a discharge port 102 are arranged on the cover body 10. When the ball mill is loaded, the experimenter can deliver the material formed after batching into the ball mill chamber from the feed port 101. Specifically, the slurry enters the feed pipe 30 from the feed port 101 and enters the ball mill chamber from the open port along the feed pipe 30. When the ball mill is unloaded, the ground slurry can flow out from the discharge port 102 along the feed pipe 30 for subsequent processing.

[0056] In this embodiment, the feed pipe 30 is configured to be deformable, and the feed pipe 30 can be stretched or bent. Specifically, one end of the feed pipe 30 can be tightened toward the other end or stretched away from the other end, and one end of the feed pipe 30 can be bent toward other directions relative to the other end, so that the position of the cover body 10 and the open mouth can be changed, and then the position of the feed port 101 and the discharge port 102 in space can be changed.

[0057] In this embodiment, the cover body 10 is arranged to move between a working position and a unloading position. When in the working position, the cover body 10 is arranged opposite to the open opening, and the end cover 100 and the cylinder body operate as a whole to perform the grinding operation. The feed port 101 and the discharge port 102 on the cover body 10 can be blocked, so that the cover body 10 can seal the feed pipe 30 and further seal the ball mill chamber.

[0058] When in the unloading position, the discharge port 102 of the cover body 10 is lower than the bottom of the ball mill chamber, and the discharge port 102 can be partially or completely lower than the bottom of the ball mill chamber. When the cover body 10 moves toward the unloading position, the end of the feed pipe 30 connected to the cover body 10 can bend and stretch downward, so that the cover body 10 moves downward as a whole, so that the discharge port 102 is partially or completely lower than the bottom position of the ball mill chamber in the up and down directions. The open port and the discharge port 102 of the cover body 10 are reliably connected through the feed pipe 30. Under the action of gravity, the slurry ground in the ball mill chamber can flow along the inner wall surface of the ball mill chamber into the feed pipe 30 and flow toward the lower discharge port 102, so as to be discharged from the ball mill.

[0059] Furthermore, after the slurry is unloaded, when the experimenter cleans the ball mill chamber, the cover body 10 can also be in a unloading state. The experimenter sprays the cleaning liquid into the ball mill chamber from the liquid inlet, and the cleaning liquid sprays the inner wall of the ball mill chamber, so that the residual slurry flows out from the discharge port 102 with the cleaning liquid, thereby completing the cleaning of the ball mill chamber.

[0060] In this embodiment, a deformable material delivery pipe 30 is arranged on the end cover 100, and the material delivery pipe 30 is connected to the open mouth of the ball mill chamber and is connected to the cover body 10. A discharge port 102 is arranged on the cover body 10, so that when the experimenter unloads and cleans the ball mill, the experimenter can move the position of the cover body 10 to make the discharge port 102 on the cover body 10 lower than the bottom of the ball mill chamber, so as to unload and clean the ball mill. The operation is simple and convenient, and the physical loss and safety risks when manually lifting the cylinder body are avoided, and the time spent on lifting the cylinder body for unloading and cleaning is saved, thereby greatly reducing the workload of the experimenter and greatly improving the unloading efficiency of the experimenter.

[0061] According to the end cover 100 for a ball mill according to the embodiment of the utility model, a feed pipe 30 and a cover body 10 are arranged, and the cover body 10 is provided with a feed port 101 and a discharge port 102 which are connected to the feed pipe 30. The feed pipe 30 is deformable and connected to the cover body 10 and the open opening of the cylinder body, so that the cover body 10 can be moved to the unloading position for unloading and cleaning operations. The operation is convenient and fast, manpower is saved, the workload of the experimenters is greatly reduced, and the work efficiency is improved.

[0062] In some embodiments of the present invention, reference Figure 1 As shown, the material delivery pipe 30 may be a corrugated pipe.

[0063] In this embodiment, the feed pipe 30 is configured as a bellows, which has good expansion and contraction deformation capabilities and can well meet the use requirements of the feed pipe 30 for expansion and contraction deformation and bending deformation.

[0064] In some embodiments of the present invention, the material delivery pipe 30 may be a rubber member, or the material delivery pipe 30 may be a plastic member.

[0065] In this embodiment, the feed pipe 30 is set as a rubber part or a plastic part. In this embodiment, the feed pipe 30 is set as a rubber part or a plastic part, which can make the feed pipe 30 have good elastic properties and enable the feed pipe 30 to be stably and reliably connected between the cover body 10 and the cylinder body during use.

[0068] In one embodiment of the present invention, Figure 1 As shown, the connecting pipe 20 may be provided with a connecting flange 21, and the connecting flange 21 extends in a ring shape along the circumference of the connecting pipe 20. In the working position, the cover body 10 is detachably connected to the connecting flange 21.

[0069] In this embodiment, a connecting flange 21 is provided on the connecting pipe 20, and the cover body 10 is detachably connected to the connecting flange 21. When the end cover 100 is assembled with the cylinder body, the portion of the connecting pipe 20 with the connecting thread extends into the open port and is threadedly connected with the open port, so that the connecting pipe 20 is fixed to the cylinder body, and the connecting flange 21 extends in a ring shape along the circumference of the connecting pipe 20. The connecting flange 21 can play a role of limiting and fixing when the connecting pipe 20 is threadedly connected with the open port, so that the connecting pipe 20 can be screwed into place with the open port, and the connecting flange 21 can abut against the outer edge of the open port, so that it can have a sealing effect to a certain extent.

[0070] The cover body 10 and the connecting flange 21 are detachably connected, so that the relative positions of the two ends of the feed pipe 30 are fixed. Specifically, when the cover body 10 and the connecting flange 21 are fixed, the feed pipe 30 can be in a tightened state, so that the overall structure of the feed pipe 30 can be in a relatively stable state, and the cover body 10 can be stably in the working position, so that the end cover 100 can be stably and reliably assembled with the cylinder for grinding operations.

[0071] When the experimenter feeds the material into the ball mill chamber, the slurry enters from the feed port 101 and can quickly flow into the ball mill chamber through the tightened feed pipe 30. When the experimenter performs the unloading operation, the cover body 10 can be disassembled and separated from the connecting flange 21, so that the feed pipe 30 can be freely extended and bent, so that the cover body 10 can be conveniently moved to the unloading position as needed.

[0072] In some embodiments of the present invention, Figure 5-Figure 8 As shown, the end cover 100 may further include a fixing member 80, which is sleeved on the circumferential outer side of the feed pipe 30, and the fixing member 80 is detachably connected to the cover body 10 and the cylinder body.

[0073] In this embodiment, a fixing member 80 is provided, and the fixing member 80 is sleeved on the circumferential outer side of the material delivery pipe 30. Specifically, the fixing member 80 can extend in a ring shape along the circumference of the material delivery pipe 30. In this embodiment, the fixing member 80 is detachably connected to the cover body 10 and the cylinder body, the fixing member 80 is detachably connected to the cylinder body, and the cover body 10 is detachably connected to the fixing member 80, so that the two ends of the material delivery pipe 30 are relatively fixed, and the cover body 10 can be stably and reliably in the working position. When the ball mill is unloading, the cover body 10 can be disassembled and separated from the fixing member 80, so that the material delivery pipe 30 can be freely stretched and bent, so that the cover body 10 can move to the unloading position.

[0074] In this embodiment, the fixing member 80 is sleeved on the circumferential outer side of the feed pipe 30, and the fixing member 80 can play a good protective role on the feed pipe 30, so that the feed pipe 30 remains stable when the cylinder is running. The fixing member 80 is fixedly connected to the cover body 10 and the connecting flange 21, which can play a good fixing role on the feed pipe 30, so that the feed pipe 30 can be stably kept in a tightened state, thereby reducing the impact of vibration on the feed pipe 30 during the movement of the ball mill, and making the end cover 100 more stable and reliable when the ball mill is running. It can be understood that the feed pipe 30 has a certain thickness after tightening. In this embodiment, the cover body 10 and the cylinder are connected and fixed by the fixing member 80, and the fixing member 80 can fill the gap of the feed pipe 30, so that the connection and fixation of the cover body 10 and the cylinder are more stable and reliable.

[0092] In this embodiment, a feed funnel 60 is provided, and the feed funnel 60 is threadedly connected with the feed port 101. When the experimenter feeds into the ball mill chamber, the connection portion 62 of the feed funnel 60 is threadedly connected with the feed port 101, and the slurry can be poured from the funnel portion 61 of the feed port 101, so that the slurry can flow into the ball mill chamber along the feed funnel 60. The funnel portion 61 and the connection portion 62 can cooperate to play a good guiding role for the slurry, mitigate the impact of the slurry on the inner wall surface when it flows into the ball mill chamber, and play a good role in blocking the splashing of the slurry when it enters the ball mill chamber, so that the experimenter can conveniently and smoothly feed the ball mill. The feed funnel 60 is arranged on the side of the cover body 10 away from the feed pipe 30, that is, the feed funnel 60 is arranged on the outside of the end cover 100. The feed funnel 60 has a simple structure and good use effect.

[0093] In some embodiments of the present invention, Figure 13-Figure 15 As shown, the funnel portion 61 and the connecting portion 62 may have an angle. It is understandable that when the experimenter feeds into the ball milling chamber, the cover body 10 of the end cover 100 is generally in the working position, and the feed port 101 of the end cover 100 is located on one side of the cylinder axial direction. It is inconvenient to feed into the ball milling chamber along the cylinder axial direction. In this embodiment, the funnel portion 61 and the connecting portion 62 are set to have an angle, so that after the feed funnel 60 is connected to the feed port 101, the opening of the funnel portion 61 of the feed funnel 60 can be arranged upward, and the experimenter can conveniently pour the material from the funnel portion 61 of the feed funnel 60, and the material flows stably into the ball milling chamber under the diversion effect of the feed funnel 60, so that the experimenter is more convenient and quick when feeding.

[0095] In this embodiment, a guide member 12 is provided at the discharge port 102, so that when the ball mill is unloading, the slurry can flow out along the guide member 12 after flowing out of the discharge port 102, so as to avoid the slurry flowing on the surface of the cover body 10, thereby reducing the loss of the slurry and the contamination of the cover body 10 by the slurry. When unloading, the end of the guide member 12 can extend into the unloading bucket for storing the slurry, so as to effectively reduce the splashing of the slurry, so that the ball mill can keep the end cover 100 and the external environment clean during the unloading process, thereby reducing the cleaning time and reducing the workload of the experimenter. Optionally, the guide member 12 is a guide nozzle.

[0096] In some embodiments of the present invention, Fig.11 and Fig.12 As shown, the end cover 100 may further include an inlet connector 70 , which is a tube body, and the inlet connector 70 is detachably connected to the feed port 101 .

[0097] In this embodiment, an inlet connector 70 is provided, which can guide the external cleaning equipment when the ball milling chamber is cleaned. For example, when the external cleaning equipment is an alcohol spray gun, the alcohol spray gun can be inserted into the inlet connector 70, and the alcohol spray gun sprays alcohol from the inlet connector 70 into the ball milling chamber, and the alcohol rinses the inner wall of the ball milling chamber and carries the participating slurry out from the discharge port 102. The inlet connector 70 of this embodiment is a tube body, which can facilitate the insertion of the spray gun. The end of the inlet connector 70 that cooperates with the spray gun can be set according to the size of the spray gun, so that the inlet connector 70 can better cooperate with the spray gun for cleaning operations.

[0098] In this embodiment, the inlet connector 70 is provided to facilitate cooperation with an external cleaning device, so that the external cleaning device can conveniently and reliably spray from the feed port 101 into the ball mill chamber for cleaning. The inlet connector 70 has a simple structure and is easy to use. Optionally, the inlet connector 70 is threadedly connected to the feed port 101.

[0099] In one embodiment of the present invention, Fig. 20 As shown, the inlet connector 70 may be provided with a third sealing ring 71, and the third sealing ring 71 abuts against the inner wall of the feed port 101. In this way, the gap between the outer peripheral surface of the inlet connector 70 and the inner wall surface of the feed port 101 can be reliably sealed, thereby preventing the dirty materials generated during the cleaning process of the ball mill chamber from flowing out of the feed port 101 and polluting the environment.

[0100] In some embodiments of the present invention, Figure 1 As shown, the cover body 10 may be provided with an armrest 11, which makes it easy for the experimenter to move and control the cover body 10, and has a simple structure and is easy to use.
