[0028] It should be understood that the embodiments of the present utility model shown in the exemplary embodiments are merely illustrative. Although only a few embodiments have been described in detail in the present utility model, those skilled in the art can easily appreciate that various modifications are feasible without substantially departing from the teachings of the subject matter of the present utility model. Accordingly, all such modifications should be included within the scope of the present utility model. Without departing from the gist of the present utility model, other substitutions, modifications, variations and deletions can be made to the design, operating conditions and parameters, etc. of the following exemplary embodiments.
[0029] To make the objectives, technical solutions and advantages of the present utility model more clear and understandable, the following further elaborates on the embodiments of the present utility model in detail with reference to specific embodiments and the accompanying drawings.
[0030] As Figure 1 and 2 shown, Figure 1 and 2 respectively show the front view and top view of the structure of the rear cover of a small ball mill used in a laboratory in the prior art. The structure of the rear cover of the small ball mill in the prior art is generally in the shape of a conical tower, which consists of three components: a plug 1 with a sealing gasket (not shown), a snap device 2, and a screw 5. The snap device 2 is in the shape of a conical tower. A first circular gripping ring 3 is provided at the upper end of the snap device 2, and two protruding parts 4 are provided at the lower end of the snap device 2 on opposite sides. One end of the screw 5 is connected to the plug 1, which is a movable connection here, not fixedly dead. The other end needs to rotate through the snap device 2 and be exposed. The top of the other end of the screw 5, that is, the top end, is exposed and is designed as a square, and is loosened or tightened by a special tool. During operation, when raw materials are added to the small ball mill, the operator holds the snap device 2 by grasping the first circular gripping ring 3 of the rear cover, aligns the two protruding parts 4 of the snap device 2 with two special grooves (not shown) at the rear feed port of the small ball mill. When the snap device 2 is rotated, the protruding parts 4 move to other areas outside the grooves, and then the operator rotates the screw 5 clockwise with a special tool. At this time, the screw 5 pushes the plug 1 to block the rear feed port of the small ball mill, so as to ensure that the pulp will not leak out during the operation of the small ball mill.
[0031] However, in the above-mentioned rear cover of the small ball mill used in the laboratory in the prior art, the designed first circular gripping ring 3 is short and shallow. During the grinding process, water droplets often adhere to it. During the taking operation, the rear cover is prone to slipping and causing injury to people's feet. Therefore, the present utility model has been improved based on the structure of the rear cover of the existing small ball mill used in the laboratory. An additional gripping ring structure needs to be added to the structure of the rear cover of the small ball mill in the prior art to make it more convenient, labor-saving and safe to grip and take the rear cover.
[0032] As Figure 3 and 4 shown,Figure 3 and 4 respectively show the front view and top view of the structure of the rear cover of the small ball mill for laboratory provided by the present utility model. As shown in the figure, the present utility model provides a rear cover of a small ball mill for laboratory, including: a plug 1; a snap device 2, the snap device 2 is in the shape of a conical tower, a first circular grip ring 3 is arranged at the upper end of the snap device 2, and two protruding parts 4 located on opposite sides are arranged at the lower end of the snap device 2; a screw rod 5, one end of the screw rod 5 is movably connected to the plug 1, and the other end of the screw rod 1 is rotatably connected to the snap device 2 and passes through the upper end of the snap device 2 and is exposed outside; and a second circular grip ring 6, the second circular grip ring 6 is connected to the snap device 2 and is adjacent to the first circular grip ring 3.
[0033] Compared with the structure of the rear cover of the small ball mill in the prior art, an additional structure of a second circular grip ring 6 is added to the structure of the rear cover of the small ball mill provided by the present utility model, making it more convenient, labor-saving and safe to grip and take the rear cover.
[0034] In the rear cover of the small ball mill for laboratory provided by the present utility model, as Figure 3 and 4 shown, the second circular grip ring 6 is welded to the snap device 2 through at least four upright posts (not shown). Preferably, the second circular grip ring 6 is welded to the snap device 2 only through four upright posts. Of course, the number of upright posts can also preferably be six or eight. This structure enables the second circular grip ring 6 to better connect to the snap device 2.
[0035] In the rear cover of the small ball mill for laboratory provided by the present utility model, as Figure 3 and 4 shown, when the second circular grip ring 6 is welded to the snap device 2 only through four upright posts, one ends of the four upright posts are welded at the four symmetric corners of the second circular grip ring 6, and the other ends of the four upright posts are welded on the snap device 2 and are adjacent to the first circular grip ring 3. The design of this structure ensures the stability of the design of the second circular grip ring 6 and is convenient for the staff to better grip or pick up the rear cover through the second circular grip ring 6.
[0036] In the rear cover of the small ball mill for laboratory provided by the present utility model, as Figure 3 and 4 shown, preferably, the second circular grip ring 6 and all the upright posts can be made of stainless steel solid round bars. This ensures the firmness or solidity of the second circular grip ring 6 and all the upright posts.
[0037] In the rear cover of the small ball mill for laboratory use provided by the present utility model, the stainless-steel solid round bar is a 304 stainless-steel solid round bar with a diameter of 6 mm, the diameter of the second circular gripping ring 6 is 49 mm, and the lengths of the columns are all 50 mm. On the one hand, this can save the materials of the second circular gripping ring 6 and the columns, and on the other hand, designing structural components with appropriate sizes is more convenient for the staff to use.
[0038] In the rear cover of the small ball mill for laboratory use provided by the present utility model, as Figure 3 and 4 shown, preferably, the plug 1 is provided with a sealing gasket (not shown). This can make the plug have stronger sealing performance when blocking the feed inlet of the ball mill, ensuring that the pulp will not leak out during the operation of the ball mill.
[0039] In the rear cover of the small ball mill for laboratory use provided by the present utility model, as Figure 3 and 4 shown, preferably, the top (tip) of the other end of the screw 5 is designed in a square shape. This is convenient for the screw 5 to be loosened or tightened using a special tool.
[0040] In the rear cover of the small ball mill for laboratory use provided by the present utility model, as Figure 3 and 4 shown, the convex part 4 aligns with the groove of the rear feed inlet of the small ball mill and moves to other areas outside the groove as the buckle device 2 rotates. First, the convex part 4 aligning with the groove of the rear feed inlet facilitates the installation of the entire rear cover onto the small ball mill. Secondly, the convex part 4 moving to other areas outside the groove as the buckle device 2 rotates enables the rear cover of the small ball mill to be buckled onto the small ball mill through the buckle device 2.
[0041] In the rear cover of the small ball mill for laboratory use provided by the present utility model, as Figure 3 and 4 shown, preferably, the screw 5 is designed to rotate clockwise to push the plug 1 to block the rear feed inlet of the small ball mill. This design is convenient for the staff to apply force to fix the relevant structure.
[0042] When the rear cover of the small ball mill for laboratory use provided by the present utility model is in use, after the raw materials are added to the small ball mill, the staff can directly hold the second circular gripping ring 6 and the first circular gripping ring 3 of the rear cover to hold the buckle device 2, align the two convex parts 4 of the buckle device 2 with the two special grooves of the rear feed inlet of the small ball mill. When rotating the buckle device 2, the convex parts 4 move to other areas outside the grooves, and then use a special tool to rotate the screw 5 clockwise. The screw 5 pushes the plug 1 to block the rear feed inlet of the small ball mill, thereby ensuring that the pulp will not leak out during the operation of the small ball mill.
[0043] Therefore, adding a second circular grip ring 6 to the rear cover structure of the present utility model is the main innovation point of the present utility model. The newly added second circular grip ring 6 is designed as a circular ring, preferably connected to the buckle device by four columns and adjacent to the existing first circular grip ring 3. The second circular grip ring 6 is designed as a circle because when the small ball mill is running, the rear cover will rotate accordingly. If it is designed as a square, it is prone to collision accidents during rotation, while a circle can avoid such accidents.
[0044] For the second circular grip ring 6 and the columns added to the rear cover structure of the present utility model, their sizes and manufacturing methods are both made of 304 stainless steel solid round bars with a diameter of 6 mm. The second circular grip ring 6 is made into a ring with a diameter of 49 mm, and the length of the columns is 50 mm. Specifically, one end of the four columns is first welded to the four symmetric corners of the ring, and then the other end of the columns is welded to the buckle device 2 and adjacent to the existing first circular grip ring 3.
[0045] Therefore, an additional second circular grip ring 6 is provided in the structure of the rear cover of the small ball mill provided by the present utility model, making it more convenient, labor-saving and safe to grip and take the rear cover.
