Description

Technical Field

[0001] This utility model belongs to the field of ball mill technology, and in particular relates to a ball mill end cap split device. Background Technology

[0002] A ball mill works by placing materials and grinding balls inside a drum. The drum rotates, and the agitator blades inside stir, mix, and grind the materials and grinding balls. After grinding, dust adheres to the inner wall of the drum. Before grinding different materials, the inside of the drum must be cleaned. Ball mill drums typically have a window for cleaning the interior. For large ball mills, workers can enter the drum through this window for cleaning. However, for small and medium-sized ball mills, due to their size, it is difficult or impossible for workers to enter the drum through the window for cleaning. Therefore, cleaning the interior of small and medium-sized ball mills... The general procedure is to first remove the bolts connecting the end cap to the drum body, then use an overhead crane in the workshop to lift the end cap open. Workers then enter the drum body to clean the inside of the drum. After cleaning, the overhead crane lifts the end cap back to the designated position and connects it to the drum body with bolts. However, this process presents several problems. Due to the weight of the end cap, after the overhead crane lifts it open, the vertical height of the end cap needs to be lowered to prevent the crane chain from breaking and causing the end cap to fall, which would pose a safety hazard. Furthermore, when lifting the end cap back to its original position, the top, bottom, left, and right positions of the end cap must be considered, making the operation very cumbersome and labor-intensive.

[0003] To this end, the applicant developed a small to medium-sized ball mill that is easy to open the end cover for cleaning the inside of the drum. Utility Model Content

[0020] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0021] In the description of this utility model, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," and "right," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] As attached Figures 1 to 6As shown, this utility model provides a ball mill end cover separation device, including a base 1 and a moving component 2 disposed on the base 1. The moving component 2 is connected to the ball mill end cover assembly 3 and is used to drive the end cover assembly 3 to close one end opening of the ball mill cylinder 4 and open one end opening of the ball mill cylinder 4. Specifically, after grinding the previous batch of material, the inside of the cylinder 4 needs to be cleaned to facilitate grinding the next batch of material. First, the worker removes the bolts connecting the end cover assembly 3 and the cylinder 4. The moving component 2 is used to regularly separate and close the end cover assembly 3 connected to the cylinder 4. After the end cover assembly 3 is separated from the cylinder 4, the worker can enter the inside of the cylinder to clean it. After cleaning, the moving component 2 is used to reattach the end cover assembly 3 to the cylinder 4, and the worker then uses bolts to lock the end cover assembly 3 and the cylinder 4 together.

[0024] Preferably, this embodiment provides a scheme for opening the end cap assembly 3 from the cylinder body 4. The moving component 2 is a horizontal moving mechanism 21, which is used to move the end cap assembly 3 in the horizontal direction so that the end cap assembly 3 fits and separates from the cylinder body 4. Under the drive of the horizontal moving mechanism 21, the end cap assembly 3 moves back and forth in the axial direction, which has the advantages of facilitating the opening of the cylinder body 4 and facilitating the connection between the end cap assembly 3 and the cylinder body 4.

[0025] Specifically, the end cap assembly 3 reciprocates relative to the cylinder body 4. The horizontal moving mechanism 21 includes a moving frame 211, an end cap connecting frame 212, a power unit 213, a sliding sleeve 214, and a slide rail 215. The sliding sleeve 214 is connected to the crossbeam of the base 1, and the slide rail 215 is fitted inside the sliding sleeve 214. The end cap assembly 3 is connected to the free end of the slide rail 215 through the end cap connecting frame 212. The power unit 213 is connected to the slide rail 215 for driving the slide rail 215 to reciprocate within the sliding sleeve 214. The crossbeam consists of two horizontal plates spaced at a predetermined distance, with through grooves to allow the sliding... The sleeve 214 is set and fixed in the through groove. The slide rail 215 is clearance-fitted with the sliding sleeve 214. The slide rail 215 slides in the sliding sleeve 214 through the power unit 213 to drive the end cover connecting frame 212 to perform reciprocating movement. The slide rail 215 sleeve and the slide rail 215 can also be in the form of a linear guide pair or a linear bearing. It should be noted that there can be two sets of sliding sleeves 214 and slide rails 215 in the moving component 2. The two sets of sliding sleeves 214 and slide rails 215 are set parallel to each other at a predetermined distance. Of course, there can also be only one set of sliding sleeves 214 and slide rails 215. However, the stability of setting two sets is better than that of setting one set.

[0026] It is understandable that the slide rail 215 and the sliding sleeve 214 are clearance-fitted. However, due to the weight of the end cap connecting bracket 212 and the end cap assembly 3, the free end of the slide rail 215 experiences greater gravity as the end cap assembly 3 moves further away from the cylinder body 4. This can cause the slide rail 215 and the sliding sleeve 214 to not move in parallel. When the slide rail 215 moves at an angle relative to the sliding sleeve 214, it may cause the reciprocating motion of the slide rail 215 within the sliding sleeve 214 to be impeded. Therefore, the horizontal moving mechanism 2... 1 also includes a first balance adjustment unit 216 and a second balance adjustment unit 217. The first balance adjustment unit is located on the side of the sliding sleeve 214 near the cylinder body 4, and the second balance adjustment unit 217 is located on the side of the sliding sleeve 214 near the end cap assembly 3. The first balance adjustment unit 216 presses down the slide rail 215 located near the end of the cylinder body 4, and the second balance adjustment unit 217 pushes up the slide rail 215 located away from the end of the cylinder body 4. This arrangement can ensure that the reciprocating movement of the slide rail 215 in the sliding sleeve 214 is smooth.

[0027] Specifically, the first balance adjustment unit 216 includes a balance frame 2161, a balance wheel 2162, and an adjustment screw 2163. The balance wheel 2162 is movably connected to the balance frame 2161 via an adjustment block 2164. The balance frame 2161 has an adjustment threaded hole, and the free end of the adjustment screw 2163 passes through the adjustment threaded hole and abuts against the adjustment block 2164. The structure of the second balance adjustment unit 217 is the same as that of the first balance adjustment unit 216. The balance wheel 2162 is a rotating shaft with a bearing. A wheel is mounted on the bearing. Both ends of the rotating shaft are connected to the adjustment block 2164 via a bearing. The transverse interface of the balance frame 2161 is shaped like a "U". The balance frame 2161 is shaped like a "" and fitted onto the sliding sleeve 214. Long, narrow grooves are provided on the vertical plates on both sides of the balance frame 2161. Adjusting blocks 2164 are located inside the vertical plates. Bolts pass through the long, narrow grooves and are threadedly connected to the adjusting blocks 2164. The upper and lower horizontal plates of the balance frame 2161 have threaded holes. Adjusting screws 2163 are threaded through the upper or lower horizontal plate and then abut against the adjusting blocks 2164. By turning the adjusting screws 2163, the axial position of the adjusting blocks 2164 can be adjusted, thereby ensuring that the balance wheel 2162 is in the appropriate position. With the cooperation of the first balance adjustment unit 216 and the second balance unit, the axial reciprocating movement of the slide rail 215 within the sliding sleeve 214 can be ensured to be smooth.

[0028] Understandably, the balancing unit ensures smooth axial reciprocating movement of the slide rail 215 within the sliding sleeve 214. However, during reciprocating movement, it may wobble left and right, causing the slide rail 215 to move awkwardly within the sliding sleeve 214. To address this, the balancing wheel 2162 has a radially arranged annular groove 2165. The upper and lower ends of the slide rail 215 are each provided with an elongated protrusion 2166 that matches the width of the annular groove 2165. The sliding sleeve 214 has a through groove, and part of the structure of the balancing wheel 2162 passes through the through groove. The elongated protrusion 2166 matches the annular groove 2165. The cooperation between the elongated protrusion 2166 and the groove ensures the reciprocating movement of the slide rail 215 within the sliding sleeve 214.

[0029] It is understood that the end cap assembly 3 includes a feed end cap assembly 3 and a discharge end cap assembly 3, which are respectively located at both ends of the cylinder body 4. The feed end cap assembly 3 and the discharge end cap assembly 3 are each driven by a set of moving units.

[0030] The above embodiments describe how the end cap assembly 3 is horizontally reciprocated by the moving component 2 to fit or open the cylinder body 4.

[0031] As attached Figure 7 and Figure 8 As shown, this embodiment provides a scheme for a flip-type opening end cap assembly 3. The moving component 2 is an axial flipping mechanism 22, which is used to flip the end cap assembly 3 so that the end cap assembly 3 fits and opens relative to the cylinder body 4. The flipping mechanism 22 is pivotally connected to the base 1 via a rotating shaft, and the end cap assembly 3 is connected to the flipping mechanism 22 via a connecting frame. When the end cap assembly 3 needs to be opened, the worker removes the bolts connecting the end cap assembly 3 to the cylinder body 4, and then opens the end cap assembly 3 at an angle to the cylinder body 4 with the rotating shaft as the center. After cleaning the inside of the cylinder body 4, the end cap assembly 3 is reset with the rotating shaft as the center.

[0032] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of the appended claims of this utility model.
