Description

Technical Field

[0001] This utility model belongs to the field of ball milling devices, and specifically relates to an aluminum ash ball milling device. Background Technology

[0002] Aluminum ash refers to the waste residue and dust generated during aluminum smelting, casting, and processing. It is mainly composed of aluminum oxide, metallic aluminum, silicon, iron, and other impurities.

[0003] A search revealed a utility model patent with authorization announcement number CN215464877U, which discloses a ball mill for aluminum ash. The ball mill includes a cylinder, an inlet communicating with its inner cavity on the side wall of the cylinder, and a door communicating with the inner cavity inside the inlet. The ball mill cylinder is connected to a frame for fixing the cylinder via a coupling. A roller gear is fitted on the side wall of the ball mill cylinder, and a drive gear meshes with the lower part of the roller gear. A motor is also located on one side of the ball mill cylinder, and an outlet is located at one end of the cylinder. A receiving device is located below the outlet, including a receiving bucket containing a filter bucket. Several filter holes are perforated on the bottom plate of the filter bucket. This receiving bucket facilitates the collection of aluminum ash, and the filter bucket inside filters out unqualified aluminum ash through the filter holes at its bottom. The unqualified ash is then poured into the ball mill for secondary processing, improving the quality of the aluminum ash product.

[0004] Currently, conventional ball mill structures directly convey or screen the milled material during discharge. However, since aluminum ash waste generates a large amount of dust during ball milling, if dust prevention and dust reduction treatment are not carried out during discharge, a large amount of dust can easily overflow during ball milling, causing harm to the surrounding environment. Summary of the Invention

[0005] The purpose of this invention is to provide an aluminum ash ball milling device that solves the problems of conventional ball milling structures. It treats dust during the discharge of aluminum ash after ball milling and can stably collect the aluminum ash material after ball milling.

[0006] To achieve the above objectives, this utility model provides an aluminum ash ball milling device, including a base. Two legs are fixedly connected to the upper end of the base, and each leg has a dust cover fixedly installed at its upper end. Symmetrically distributed sealing plates are fixed to both ends of the dust covers. The sealing plates primarily serve a load-bearing function during the ball milling process. Lubricating grease can be applied to the rotating connection between the sealing plates and the ball milling cylinder to help reduce wear from sliding friction. The ball milling cylinder is rotatably connected to the center of the two sealing plates. The surface is perforated with several sieve holes, which serve as a material leakage structure. The diameter of the sieve holes is smaller than the diameter of the grinding media balls used in the ball mill to prevent the media balls from leaking out during ball milling. A cylinder cover is provided at one end of the ball mill cylinder. A motor is fixedly connected to the surface of the support legs via a bracket. The output shaft of the motor is fixedly connected to the closed end of the ball mill cylinder. A discharge port penetrating through the interior is provided at the lower end of the dust cover. A material collection mechanism is also provided at the lower end of the dust cover, with the material collection mechanism corresponding to the position of the discharge port. A dust suppression mechanism is provided at the upper end of the dust cover.

[0007] The principle of this utility model is as follows: During ball milling, the grinding media balls are fed into the ball mill cylinder through the feed inlet beforehand. Then, the aluminum ash material to be ball milled is fed into the ball mill cylinder. The feed inlet is sealed by the external thread of the cylinder cover and the internal thread of the ball mill cylinder feed inlet. The sieve holes are mainly used for ball milling and screening, so that the final ball-milled particles can pass through the sieve holes. The sieve holes can also simultaneously allow the particles produced during ball milling to pass through, achieving unified screening of granular and powdered materials. When the motor power is turned on, the motor can drive the ball mill cylinder to rotate, so that the grinding media balls and aluminum ash waste slag can be ball-milled in contact. The material falling through the sieve holes will enter the material box for collection. The dust cover can achieve closed processing to prevent dust from overflowing.

[0008] After the ball milling process has finished for a certain period of time, the material box completes material collection. By rotating the knob, the threaded sleeve and the threaded post are separated, allowing the threaded post to disengage from the collar. This separates the material box from the dust cover, completing the cleaning of the material box. To further collect the floating dust inside the dust cover, the air pump is powered on when the material box needs cleaning. The air pump generates suction, and through the cooperation of the two suction pipes and the suction interface, the dust is sucked into the dust collection bag for collection, completing the dust reduction work.

[0009] The beneficial effects of this utility model are as follows: materials and grinding media can be normally fed in through the opening of the ball mill cylinder, and the opening can be closed through the cylinder cover. When the motor power is turned on, the ball mill cylinder can be driven to rotate through the output shaft of the motor. Based on the sealing plate and protective cover, the stability of the ball mill cylinder and the prevention of dust overflow can be ensured when grinding aluminum ash materials.

[0010] During the continuous ball milling process, the aluminum ash material is continuously crushed into smaller pieces. The powder and slag will continuously fall through the sieve holes into the material box in the material collection mechanism for dust collection. The material box is also easy to disassemble and assemble quickly through the locking method of threaded column and threaded cap.

[0011] When materials need to be removed from the material box, in order to prevent dust from overflowing from the dust cover, the power of the air pump is turned on. The air pump can generate suction to achieve the effect of air extraction. Through the two combined suction pipes and the suction interface at the end, the dust in the dust cover can be extracted and sent into the dust collection bag in the cylinder by the air pump for collection, thus realizing the dust reduction operation.

[0012] Furthermore, both the dust cover and the ball mill cylinder are tilted cylindrical structures, and the dust cover covers the outside of the sieve holes. During ball milling, the dust cover provides dust protection and covers all sieve holes.

[0013] Furthermore, the inner wall of the opening end of the ball mill cylinder is a conical structure, and an internal thread is provided on the inner wall of the opening. The surface of the cylinder cover is provided with an external thread, and the external thread and the internal thread are threaded together. The cylinder cover can be quickly disassembled and assembled with the opening position of the ball mill cylinder by means of threaded connection, so as to ensure the stable feeding and discharging of aluminum ash material and media balls.

[0014] Furthermore, the material collection mechanism includes a material box, a collar, a threaded column, and a threaded sleeve. The end face of the material box is attached to the outer surface of the dust cover, and the material box covers the port position of the discharge port. The material box is mainly used for powder and granular materials after ball milling of aluminum ash waste residue, and can achieve dustproof and sealed collection.

[0015] Furthermore, each end of the material box is fixed with a collar, and the lower end of the dust cover is fixed with a threaded post corresponding to the collar and fitted together. The surface of the threaded post is threadedly connected to a threaded sleeve that is tightly fitted to the collar. The surface of the threaded sleeve is provided with a knob, which can be used to manually rotate the threaded sleeve and has a point of force.

[0016] Furthermore, the dust suppression mechanism includes a dust suction interface, a first dust suction pipe, a second dust suction pipe, an air pump, a cylinder, a frame, and a dust collection bag. The dust suction interface is connected to and fixed to the upper end of the dust cover. Several dust suction interfaces are provided and are arranged side by side at equal intervals. Several dust suction interfaces are connected to and fixedly connected to the first dust suction pipe. The other end of the first dust suction pipe is flanged to the second dust suction pipe. The dust suppression mechanism can be started in advance when the material in the material box needs to be processed, so as to prevent dust from overflowing through the discharge port after the material box is removed. The discharge port is based on the inner arc shape of the dust cover and the funnel shape at both ends, which can ensure that the material after ball milling falls stably into the material box.

[0017] Furthermore, an air pump is fixed to the upper end of the base. The air inlet of the air pump is connected to the end flange of the second dust suction pipe. A cylinder is connected to the air outlet flange of the air pump. A frame is fixedly embedded inside the cylinder. A dust collection bag is fixedly embedded inside the frame. The air pump provides sufficient suction effect to send the dust into the dust collection bag for collection. The dust collection bag is made of non-woven fabric. Attached Figure Description

Detailed Implementation

[0024] like Figure 1 , Figure 2As shown, this embodiment provides an aluminum ash ball milling device, including a base 1. Two legs 2 are fixedly connected to the upper end of the base 1, and a dust cover 3 is fixedly installed on the upper end of each leg 2. Symmetrically distributed sealing plates 4 are fixed to both ends of the dust cover 3. The sealing plates 4 mainly serve a bearing function during the ball milling process, allowing the ball milling cylinder 5 to rotate. Lubricating grease can be applied to the rotating connection between the sealing plates 4 and the ball milling cylinder 5 to help reduce sliding friction losses. The ball milling cylinder 5 is rotatably connected to the center of the two sealing plates 4. Several sieve holes 6 are provided through the surface of the ball milling cylinder 5. Both the dust cover 3 and the ball milling cylinder 5 are tilted cylindrical structures, with the dust cover 3 covering the outside of the sieve holes 6. During ball milling, the dust cover 3 serves as a... The dustproof protection covers all the sieve holes 6, which can be used as a material leakage structure. The diameter of the sieve holes 6 is smaller than the diameter of the media balls used for ball milling, so as to prevent the media balls from leaking out during ball milling. A cylinder cover 7 is provided at one end of the ball mill cylinder 5. The inner wall of the opening end of the ball mill cylinder 5 is a conical structure and is provided with internal threads. The surface of the cylinder cover 7 is provided with external threads. The external threads and internal threads are threaded together. The cylinder cover 7 can be easily disassembled and reassembled with the opening of the ball mill cylinder 5 by means of threaded connection, so as to ensure the stable feeding and discharging of aluminum ash material and media balls. The surface of the support leg 2 is fixedly connected to the motor 8 through the bracket. The output shaft of the motor 8 is fixedly connected to the closed end of the ball mill cylinder 5. The lower end of the dust cover 3 is provided with a discharge port 11 that penetrates its interior.

[0025] See Figure 2 and Figure 3 The lower end of the dust cover 3 is also equipped with a material collection mechanism 9. The material collection mechanism 9 includes a material box 91, a collar 92, a threaded post 93, and a threaded sleeve 94. The end face of the material box 91 is attached to the outer surface of the dust cover 3, and the material box 91 covers the port of the discharge port 11. The material box 91 is mainly used for collecting powder and granular materials after ball milling of aluminum ash waste residue, and can achieve dustproof and sealed collection. The material collection mechanism 9 is positioned corresponding to the discharge port 11. The two ends of the material box 91 are respectively fixed with collars 92. The lower end of the dust cover 3 is fixed with a threaded post 93 that corresponds to and is fitted with the collar 92. The surface of the threaded post 93 is threadedly connected to a threaded sleeve 94 that is tightly fitted with the collar 92. The surface of the threaded sleeve 94 is provided with a knob, which can be used to manually rotate the threaded sleeve 94 and provides a point of force.

[0026] See Figure 2 and Figure 4The upper end of the dust cover 3 is equipped with a dust suppression mechanism 10. The dust suppression mechanism 10 includes a suction port 101, a first suction pipe 102, a second suction pipe 103, an air pump 104, a cylinder 105, a frame 106, and a dust collection bag 107. The suction port 101 is inserted through and fixed to the upper end of the dust cover 3. Several suction ports 101 are provided and are arranged side by side at equal intervals. Several suction ports 101 are inserted through and fixedly connected to the first suction pipe 102. The other end of the first suction pipe 102 is flanged and connected to the second suction pipe 103. The dust suppression mechanism 10 can be activated in advance when the material in the material box 91 needs to be processed, avoiding the need to process the material in the material box 91 after it is removed. Afterwards, the dust will overflow through the discharge port 11. The discharge port 11 is based on the inner arc shape of the dust cover 3 and the funnel shape at both ends, which can ensure that the material after ball milling falls stably into the material box 91. An air pump 104 is fixed at the upper end of the base 1. The air inlet of the air pump 104 is connected to the end flange of the dust suction pipe 103. The air outlet flange of the air pump 104 is connected to a cylinder 105. A frame 106 is fixedly embedded inside the cylinder 105. A dust collection bag 107 is fixedly embedded inside the frame 106. The air pump 104 provides sufficient suction effect to send the dust into the dust collection bag 107 for collection. The dust collection bag 107 is made of non-woven fabric.

[0027] The specific implementation process of this utility model is as follows: During ball milling, the media balls are fed in through the feed inlet of the ball mill cylinder 5 beforehand. Then, the aluminum ash material to be ball milled is fed into the ball mill cylinder 5. The feed inlet is sealed by the external thread of the cylinder cover 7 and the internal thread of the feed inlet of the ball mill cylinder 5. The sieve hole 6 is mainly used for ball milling and screening, so that the final ball milled particle size can pass through the sieve hole 6. The sieve hole 6 can also simultaneously leak out the ball milling process, realizing the unified screening of granular materials and powder materials. When the power of the motor 8 is turned on, the motor 8 can drive the ball mill cylinder 5 to rotate, so that the media balls and aluminum ash waste slag can be ball milled in contact. The material falling through the sieve hole 6 will enter the material box 91 for collection. The dust cover 3 can realize closed processing to prevent dust from overflowing.

[0028] After the ball milling process has been completed for a certain period of time, the material box 91 completes the material collection. By rotating the knob, the threaded sleeve 94 and the threaded post 93 are separated from each other, and the threaded post 93 is disengaged from the collar 92. Thus, the material box 91 can be separated from the dust cover 3, and the material box 91 can be cleaned. In order to further collect the floating dust in the dust cover 3, when it is necessary to clean the material box 91, the power supply of the air pump 104 is turned on. The air pump 104 can draw air to generate suction. Through the cooperation of the two suction pipes and the suction interface 101, the dust can be sucked into the dust collection bag 107 for collection, thus completing the dust reduction work.

[0029] This solution allows for the normal input of materials and grinding media through the opening of the ball mill cylinder 5. The opening can be closed by the cylinder cover 7. When the power of the motor 8 is turned on, the output shaft of the motor 8 can drive the ball mill cylinder 5 to rotate. Based on the sealing plate 4 and the protective cover 3, the stability of the ball mill cylinder 5 and the prevention of dust overflow can be ensured when grinding aluminum ash materials.

[0030] During the continuous ball milling process, the aluminum ash material is continuously crushed into smaller pieces. The powder and slag will continuously fall through the sieve holes 6 into the material box 91 in the material collection mechanism 9 for dust collection. The material box 91 can also be easily and quickly disassembled and assembled by the locking method of the threaded column 93 and the threaded cap 94.

[0031] When it is necessary to remove the material from the material box 91, in order to prevent the dust from overflowing from the dust cover 3, the power of the air pump 104 is turned on. The air pump 104 can generate suction to achieve the air extraction effect. Through the two combined suction pipes and the suction port 101 at the end, the dust in the dust cover 3 can be extracted and sent to the dust collection bag 107 in the cylinder 105 for collection, thereby realizing the dust reduction operation.
