[0026] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] The following is a reference to the appendix. Figures 1 to 2 This invention provides a detailed description of the volleyball recovery device 100 and the vertical mill 1000 according to embodiments of the present invention.

[0028] The vertical mill 1000 of this utility model embodiment includes a body 200 and a volleyball recovery device 100.

[0029] The volleyball recovery device 100 of this embodiment includes a collection tank 1, a drainage channel (not shown in the figure), and a mesh screen 2. The collection tank 1 has a collection chamber, which is open and located below the volleyball outlet 2001 of the main body 200 to collect the slurry and steel balls discharged from the main body 200. The collection tank 1 is positioned in a first direction (e.g., in the first direction). Figure 1The vertical mill 1000 has a first retaining wall 11 and a ramp 12 at its two ends (in the front-back direction). The first retaining wall 11 is adjacent to or attached to the body 200 of the vertical mill 1000. The height of the ramp 12 gradually increases in the direction away from the body 200 of the vertical mill 1000, and the height of the ramp 12 is lower than that of the first retaining wall 11. The drain channel is located at the bottom of the collection tank 1, with the inlet of the drain channel located inside the collection tank 1 and the outlet of the drain channel located outside the collection tank 1. The partition net 2 is located inside the collection tank 1 and covers the inlet of the drain channel.

[0030] In use, the volleyball recovery device 100 of this embodiment is installed below the volleyball inlet 2001 of the body 200 of the vertical mill 1000, with the first direction located in the horizontal direction, for example, the front-to-back direction. Figure 1 As shown. The volleyball recycling device 100 forms a surrounding collection chamber through the collection pool 1. The open side of the collection chamber faces the ball discharge port 2001 of the main body 200 of the vertical mill 1000. When the ball discharge port 2001 of the main body 200 is opened to discharge slurry and steel balls, the slurry and steel balls fall naturally into the collection pool 1. The slurry is discharged from the collection pool 1 through the drainage channel at the bottom of the collection pool 1, and the steel balls are blocked by the mesh 2 and naturally accumulate in the collection pool 1. After the main body 200 is emptied of slurry and steel balls, the ball discharge port 2001 is closed. Then, personnel push a trolley along the ramp 12 into the collection pool 1 to load the steel balls into the trolley for recycling and reuse.

[0031] The height of the first retaining wall 11 is higher than that of the ramp 12, which facilitates the movement of personnel on the ramp 12 and ensures that the front side of the collection pool 1 (that is, the side adjacent to the volleyball opening 2001) is higher, thus forming a protection to prevent slurry and steel balls from splashing outside the collection pool 1.

[0032] The volleyball recycling device 100 of this embodiment protects the falling slurry and steel balls in the collection pool 1, preventing splashing. It effectively separates the slurry and steel balls through the drainage channel and the mesh 2, allowing the steel balls to accumulate naturally for easy retrieval. This improves recycling efficiency, avoids multiple transfers of the steel balls, and reduces losses and safety hazards associated with such transfers. Furthermore, the volleyball recycling device 100 has a simple structure, facilitating compact configuration and saving floor space, thus reducing construction and maintenance costs.

[0033] In some embodiments, the two ends of the collection pool 1 in the second direction are a second baffle wall 13 and a third baffle wall 14, respectively, and the second direction is perpendicular to the first direction. Figure 1As shown, the second direction is the same as the left-right direction. The two ends of the second retaining wall 13 are connected to the first retaining wall 11 and the ramp 12, respectively, and the two ends of the third retaining wall 14 are connected to the first retaining wall 11 and the ramp 12, respectively. The second retaining wall 13, the ramp 12, the third retaining wall 14, the first retaining wall 11, and the bottom of the collection pool 1 form a collection cavity. The collection pool 1 is located in the middle of this second direction opposite to the volleyball outlet 2001. The drainage channel is adjacent to or passes through the second retaining wall 13 or the third retaining wall 14. Correspondingly, the partition net 2 is adjacent to the second retaining wall 13 or the third retaining wall 14.

[0034] During the discharge of slurry and steel balls from the volleyball outlet 2001, the drop area of ​​the slurry and steel balls is mainly located in the middle of the collection pool 1 in the second direction, while the partition net 2 is located at the edge of the collection pool 1 in the second direction (second retaining wall 13 or third retaining wall 14). This avoids direct impact of slurry and steel balls on the partition net 2, reduces the stress on the partition net 2, thereby reducing wear, maintenance frequency and maintenance costs of the partition net 2, and extending the service life of the partition net 2. This further reduces the maintenance costs of the volleyball recycling device 100 and the vertical mill 1000 in this embodiment of the present invention.

[0035] Furthermore, the partition 2 is a steel mesh, which connects the bottom of the collection tank 1 and the second retaining wall 13 or the third retaining wall 14. That is, when the drainage channel is adjacent to or passes through the second retaining wall 13, the steel mesh connects the bottom of the collection tank 1 and the second retaining wall 13; or when the drainage channel is adjacent to or passes through the third retaining wall 14, the steel mesh connects the bottom of the collection tank 1 and the third retaining wall 14.

[0036] Specifically, the reinforcing mesh is made of multiple welded steel bars, and the mesh size is smaller than the diameter of the steel ball. Steel bars have high strength, good wear resistance, and good corrosion resistance. The use of steel bars in mesh 2 further reduces wear, maintenance frequency, and maintenance costs, thus extending its service life.

[0037] Specifically, the front end of the second retaining wall 13 is at the same height as the first retaining wall 11, the rear end of the second retaining wall 13 is at the same height as the highest point of the ramp 12, the front end of the third retaining wall 14 is at the same height as the first retaining wall 11, and the rear end of the third retaining wall 14 is at the same height as the highest point of the ramp 12.

[0038] In some embodiments, if the size of the first retaining wall 11 in the second direction is greater than or equal to the size of the vertical mill 1000 in the second direction, then the collection pool 1 has a certain size in the second direction, thereby reducing the splashing of slurry and steel balls outside the collection pool 1 during the falling process.

[0039] Specifically, the body 200 has a base 2002, and the dimension of the first retaining wall 11 in the second direction is greater than or equal to the dimension of the base 2002 of the body 200 in the second direction.

[0040] In this embodiment, the dimension of the first retaining wall 11 in the second direction is equal to the dimension of the base 2002 of the body 200 in the second direction.

[0041] Furthermore, the dimensions of the second retaining wall 13 and the third retaining wall 14 in the first direction are greater than or equal to the dimension of the first retaining wall 11 in the second direction.

[0042] The bottom of the collection pool 1 is located 0.4-0.6m below the ground line. On the one hand, this facilitates the connection between the drainage channel and the trench in the workshop where the vertical mill is located, so that the slurry can be discharged into the trench and recycled and reused by the trench pipe network. On the other hand, it facilitates the connection between the ramp 12 and the workshop floor, so that the upper end of the ramp 12 is located at or near the ground line, which makes it easier for personnel to push carts from the ground to enter and exit the ramp 12, improving the convenience of personnel collecting steel balls.

[0043] For example, the bottom of collection pool 1 is located 0.4m, 0.5m, or 0.6m below the ground level. In this embodiment, the bottom of collection pool 1 is located 0.5m below the ground level.

[0044] Furthermore, the slope of ramp 12 is 4%-6%, which facilitates personnel pushing carts on ramp 12 while controlling the length of ramp 12, i.e., controlling the size of ramp 12 in this first direction, thus preventing slurry and steel balls from colliding in the direction of ramp 12 (e.g., Figure 2 The volleyballs splash out of the collection pool 1 in the front and back directions, thus controlling the floor space occupied by the collection pool 1 and saving the construction investment cost of the volleyball recycling device 100 of this utility model embodiment.

[0045] Specifically, the ramp 12 is provided with multiple anti-slip ribs 3, which are arranged at intervals along the first direction. The first anti-slip rib 3 protrudes from the surface of the ramp 12, which can increase friction and thus improve the safety of personnel walking on the ramp 12 and the safety of personnel in the process of retrieving steel balls.

[0046] In some embodiments, the volleyball recycling device 100 further includes a flushing assembly 4, which includes an inlet pipe 41, a valve 42, and a hose 43. One end of the inlet pipe 41 is connected to a water source, and the other end of the inlet pipe 41 is located on one side of the collection tank 1 in the second direction. The other end of the inlet pipe 41 is connected to the inlet of the valve 42, and the outlet of the valve 42 is connected to the hose 43. After the main body 200 of the vertical mill 1000 has completed discharge and the volleyball port 2001 has been closed, the valve 42 can be opened, and personnel can use the hose 43 to flush the steel balls in the collection tank 1 and the bottom of the collection tank 1, flushing the slurry on the surface of the steel balls, thereby facilitating the subsequent recycling and reuse of the steel balls. At the same time, flushing the bottom of the collection tank 1 prevents the presence of unremoved slurry at the bottom of the collection tank 1, and also facilitates the recycling of slurry.

[0047] Specifically, the hose 43 has a certain length, and the end of the hose 43 can be moved above the collection pool 1, so that personnel can rotate the end of the hose 43 to rinse different parts of the collection pool 1.

[0048] Therefore, the vertical mill 1000 of this utility model embodiment has a concentrated ball-collecting area, which can realize the separation of slurry and steel balls, and the recycling operation of slurry and steel balls is convenient. It has a simple structure, a relatively compact configuration, saves floor space, and has low construction investment and maintenance costs.
