Description

Technical Field

[0001] This utility model belongs to the field of ball mill technology, and in particular relates to a ball mill that is easy to clean the drum chamber. Background Technology

[0002] A ball mill works by placing materials and grinding balls into a drum, rotating the drum, and using agitator blades inside to 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 are usually equipped with a window for cleaning the inside. For large ball mills, workers can enter the drum through this window to clean it. 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. Therefore, for cleaning the inside of small and medium-sized ball mills, workers typically use a crane in the workshop to lift open the feed or discharge end cover, and then enter the drum through the opened end cover to clean the inside.

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

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] 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.

[0028] As attached Figures 1 to 10 As shown, this utility model provides a ball mill that facilitates cleaning of the drum chamber, including a base 1, a rotating assembly 2, a drum assembly 3, a feed end cover assembly 4, a discharge end cover assembly 5, and a first moving assembly 6. The drum assembly 3 is connected to the base 1. The rotating assembly 2 is used to drive the drum assembly 3 to rotate. The first moving assembly 6 is located at one end of the base 1 and is connected to the feed end cover assembly 4, used to drive the feed end cover assembly 4 to move closer to or away from one end of the drum assembly 3. Specifically, after grinding the previous batch of material, the inside of the drum assembly 3 needs to be cleaned to facilitate grinding the next batch of material. First, the worker removes the bolts connecting the feed end cover assembly 4 and the drum assembly 3. Then, the first moving assembly 6 can move the feed end cover assembly 4 away from the end of the drum assembly 3. After moving away, the worker can enter the inside of the drum assembly 3 to clean the inside of the drum assembly. After cleaning, the first moving assembly 6 is used to attach the feed end cover assembly 4 to the drum assembly 3. The worker then uses bolts to lock the feed end cover assembly 4 and the drum assembly 3 together.

[0029] Preferably, the first moving component 6 includes a moving frame 61, an end cap connecting frame 62, a first power unit 63, a sliding sleeve 64, and a slide rail 65. The sliding sleeve 64 is connected to the crossbeam of the base 1, and the slide rail 65 is sleeved inside the sliding sleeve 64. The feed end cap assembly 4 is connected to the free end of the slide rail 65 through the end cap connecting frame 62. The first power unit 63 is drivenly connected to the slide rail 65 to drive the slide rail 65 to reciprocate within the sliding sleeve 64. The crossbeam consists of two horizontal plates spaced at a predetermined distance, with through grooves provided to hold the sliding sleeve 64. The slide rail 65 is set and fixed in the through groove and is fitted with a clearance fit in the sliding sleeve 64. The slide rail 65 slides in the sliding sleeve 64 through the first power unit 63 to drive the end cover connecting frame 62 to perform reciprocating movement. The slide rail 65 sleeve and the slide rail 65 can also be in the form of a linear guide pair or a linear bearing. It should be noted that there are two sets of sliding sleeves 64 and slide rails 65 in the first moving component 6. The two sets of sliding sleeves 64 and slide rails 65 are arranged in parallel. Of course, there can also be only one set of sliding sleeves 64 and slide rails 65. However, the stability of setting two sets is better than setting one set.

[0030] Preferably, it is understood that the slide rail 65 and the sliding sleeve 64 are in clearance fit. Due to the weight of the end cap connecting bracket 62 and the end cap assembly, the free end of the slide rail 65 experiences greater pressure as the end cap assembly moves further away from the roller assembly 3. This can cause the slide rail 65 and the sliding sleeve 64 to not move in parallel. When the slide rail 65 moves at an angle relative to the sliding sleeve 64, the reciprocating motion of the slide rail 65 within the sliding sleeve 64 becomes unsmooth. Therefore, the first moving component 6 further includes a first balance adjustment unit 66 and a second balance adjustment unit 67. The first balance adjustment unit is located at the upper end of the sliding sleeve 64 near the roller assembly 3, and the second balance adjustment unit 67 is located at the lower end of the other side of the sliding sleeve 64. The first balance adjustment unit 66 presses down the slide rail 65 located near the roller assembly 3, and the second balance adjustment unit 67 pushes up the slide rail 65 located away from the roller assembly 3. This arrangement ensures that the reciprocating motion of the slide rail 65 within the sliding sleeve 64 is smooth.

[0031] Preferably, the first balance adjustment unit 66 includes a balance frame 661, a balance wheel 662 and an adjusting screw 663. The balance wheel 662 is movably connected to the balance frame 661 via an adjusting block 664. The balance frame 661 is provided with an adjusting threaded hole, and the free end of the adjusting screw 663 passes through the adjusting threaded hole and then abuts against the adjusting block 664. The structure of the second balance adjustment unit 67 is the same as that of the first balance adjustment unit 66. The balance wheel 662 is a rotating shaft provided with a bearing, and a wheel is arranged on the bearing. Both ends of the rotating shaft are respectively connected to the adjusting block 664 through one bearing. The transverse cross section of the balance frame 661 is in a shape of a Chinese character "kou" (mouth). The vertical plates on both sides of the balance frame 661 are provided with elongated through grooves, the adjusting block 664 is arranged on the inner side of the vertical plates, and a bolt passes through the elongated through grooves and is in threaded connection with the adjusting block 664. The two upper and lower horizontal plates of the balance frame 661 are provided with threaded holes, and the adjusting screw 663 is in threaded connection through the upper horizontal plate or the lower horizontal plate and then abuts against the adjusting block 664. By screwing the adjusting screw 663, the axial position of the adjusting block 664 can be adjusted, so that the balance wheel 662 is located at a proper position. Under the coordination of the first balance adjustment unit 66 and the second balance unit, the reciprocating movement of the slide rail 65 in the sliding sleeve 64 can be ensured to be smooth.

[0032] Preferably, it can be understood that the balance unit can ensure the smooth axial reciprocating movement of the slide rail 65 in the sliding sleeve 64. However, during the reciprocating movement, left-right shaking may still occur, which leads to unsmooth reciprocating movement of the slide rail 65 in the sliding sleeve 64. For this purpose, the balance wheel 662 is radially provided with an annular groove 6621. Both the upper end surface and the lower end surface of the slide rail 65 are provided with an elongated protrusion 651 adapted to the width of the annular groove 6621. The sliding sleeve 64 is provided with a through groove, part of the structure of the balance wheel 662 passes through the through groove, the elongated protrusion 651 is adapted to the annular groove 6621, and the cooperation of the elongated protrusion 651 and the groove can ensure the reciprocating movement of the slide rail 65 in the sliding sleeve 64.

[0033] Preferably, it can be understood that when cleaning the inside of the drum assembly 3, only the feeding end cover assembly 4, the discharging end cover assembly 5 can be opened, or both end cover assemblies can be opened. The device further includes a second moving assembly 7 connected to the discharging end cover assembly 5, the second moving assembly 7 is arranged at the other end of the base 1, and the structure of the second moving assembly 7 is the same as that of the first moving assembly 6.

[0034] Preferably, the rotating assembly 2 includes a driving motor 21, a driving wheel 22, a driven wheel 23 and a transmission belt 24. The driving wheel 22 is connected to the output shaft of the driving motor 21, the driven wheel 23 is connected to the drum assembly 3, and the driving wheel 22 is in transmission connection with the driven wheel 23 via the transmission belt 24.

[0035] Preferably, the roller assembly 3 includes a cylinder body 31, stirring bars 32, and four sets of rotating wheels 33. The four sets of rotating wheels 33 are respectively located at the four corners of the base 1. The cylinder body 31 is placed on the four sets of rotating wheels 33, and the stirring bars 32 are located on the inner wall of the cylinder body 31. The driven wheel 23 is connected to the cylinder body 31. It can be understood that the transmission belt 24 can be a belt, gear, or chain drive. Since the driven wheel is sleeved on the cylinder body, and the diameter of the cylinder body is significantly different from the diameter of the driving wheel, using a belt drive may cause the belt to slip. Using a gear drive is not conducive to the manufacturing and installation of the driven wheel. Using a chain drive is a more suitable solution.

[0036] Preferably, it is understood that the cylinder body 31 is placed directly on the four sets of rotating wheels 33. To prevent the cylinder body 31 from moving unplanned in the axial direction, the roller assembly 3 also includes two sets of limiting rings 34 and two sets of limiting wheels 35. The two sets of limiting rings 34 are respectively located at both ends of the cylinder body 31 and are located on the base 1. The side wall of one set of limiting wheels 35 abuts against the inner side wall of one set of limiting rings 34.

[0037] Preferably, it also includes a pneumatic hammer 8 mounted on the base 1 for hammering the cylinder 31; during the grinding process of the cylinder 31 rotating, some material will adhere to the cylinder 31, and if it is not treated for a long time, it will stick more and more, thus affecting the grinding effect and grinding time.

[0038] 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.
