[0002] Some applications, such as manufacturing high-precision manganese alloys or using it as a raw material for certain chemical reactions, require electrolytic manganese to have a specific particle size. Crushed electrolytic manganese allows for better mixing with other raw materials, improving product quality. For example, in the production of manganese-based materials for the electronics industry, fine electrolytic manganese particles help ensure consistent material properties.

[0003] Chinese patent publication number CN 208878709 U provides a ball mill specifically for electrolytic manganese crushing, comprising a housing with a discharge port formed below the housing; a rotating drum connected to the housing via a bearing shaft; one end of the rotating drum is connected to a screw feeder via a shaft connection; the other end is connected to a magnetic transmission device, which is connected to a motor; the magnetic transmission device includes a housing; an input shaft connected to the rotating drum is mounted within the housing; the input shaft is connected to a passive rotor; and a plurality of passive magnetic strips are evenly mounted on the passive rotor from the top.

[0004] When the electrolytic manganese crushing ball mill described in the aforementioned patent crushes electrolytic manganese, simple grinding cannot guarantee the particle size of the electrolytic manganese. Furthermore, electrolytic manganese has a high hardness, with a Mohs hardness of approximately 4. This hardness gives it a certain degree of wear resistance and deformation resistance at room temperature. The single-stage grinding method in the aforementioned patent does not allow for a good grinding process of the electrolytic manganese. Furthermore, grinding electrolytic manganese in a ball mill generates a large amount of dust, which, if not effectively handled, can be harmful to the health of operators and the environment.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1-7 In the embodiment of the present invention, a crushing device for electrolytic manganese is provided, comprising:

[0031] A jaw crusher 1 is provided with an elevator 2 at the discharge end of the jaw crusher 1, and a storage hopper 3 is provided at the discharge port of the elevator 2; the storage hopper 3 is located above the belt conveyor 4 and is fixed to a prefabricated foundation 12 by a bracket;

[0032] The end of the belt conveyor 4 is located at the feed port of the grinding mill 5, and is connected to the centrifugal separator 7 through the extraction pipe 8 at the top of the grinding mill 5, and the centrifugal separator 7 is also connected to the feeding fan 6 through the negative pressure pipe 9; the feeding fan 6 is installed in conjunction with the grinding mill 5, and a discharge pipe 11 is vertically connected above the air outlet of the feeding fan 6; the upper end of the discharge pipe 11 is connected to the storage tank 10.

[0033] By adopting the above technical solution, when crushing electrolytic manganese, larger pieces of electrolytic manganese are initially crushed by a jaw crusher 1. Through the periodic movement of the movable jaw and the static jaw, the electrolytic manganese pieces entering the crushing chamber are subjected to forces such as extrusion and splitting, thereby breaking them into smaller pieces. The crushing ratio is large, and large pieces of electrolytic manganese can be quickly crushed into medium-sized particles. The crushed electrolytic manganese is then transferred to a storage hopper 3 by an elevator 2, and then released to a belt conveyor 4 through the storage hopper 3. The belt conveyor 4 is then used to transport the electrolytic manganese to a grinding mill 5 for further crushing of the medium-sized electrolytic manganese.

[0034] The ground electrolytic manganese powder is then drawn out from the top and collected by a centrifugal separator 7 , thereby achieving both pulverization of the electrolytic manganese powder and ensuring environmental protection at the work site.

[0035] In this embodiment, the storage tank 10 is used to store small particles of electrolytic manganese, eliminating the crushing process of the jaw crusher 1; the extraction pipe 8 is connected to the feed nozzle at the upper end of the centrifugal separator 7; and the negative pressure pipe 9 is connected to the air inlet end of the feed fan 6.

[0036] By adopting the above technical solution, when the feed fan 6 is working, it can provide a negative pressure to the centrifugal separator 7, so that dust can be extracted from the mill 5. With the cooperation of the centrifugal separator 7, the separation of air and electrolytic manganese powder is achieved. Secondly, the air outlet end of the feed fan 6 blows air into the mill 5 and can form a wind force at the lower end of the discharge pipe 11, which can directly transport small particles of electrolytic manganese into the mill 5.

[0037] The coordinated use of the centrifugal separator 7 and the feeding fan 6 enables the crushing production line to form a closed loop, thereby greatly ensuring the cleanliness of the work site.

[0038] In this embodiment, the grinding mill 5 includes a grinding mill housing 51, within which a grinding roller assembly 52 is disposed. A rotating disk 521 is centrally located within the grinding roller assembly 52, and multiple grinding rollers 522 are movably connected to the exterior of the rotating disk 521 via rotating shafts. The grinding rollers rotate in contact with a grinding ring 56, which is fixed to the grinding mill housing 51. Multiple beveled scrapers 53 are disposed below the grinding roller assembly 52, arranged in a circular array on the exterior of the rotating disk 531.

[0039] Specifically, the rotating disk 521 and the rotating disk 531 are mounted on a transmission shaft 50. The transmission shaft 50 is mounted on a feed bottom housing 55 via a bearing, and the lower end of the transmission shaft 50 is connected to the grinding motor 54 via a coupling. The feed bottom housing 55 is fixed to the bottom of the mill housing 51 by bolts and is connected to the air outlet of the feed fan 6.

[0040] By adopting the above technical solution, when the feeding fan 6 transports the electrolytic manganese particles to the inside of the feeding bottom shell 55, the grinding motor 54 drives the transmission shaft 50 to rotate, and the oblique scraper 53 scoops up the electrolytic manganese particles. Under the action of centrifugal force, the electrolytic manganese particles are thrown between the grinding roller assembly 52 and the grinding ring 56, thereby achieving the grinding and crushing of the electrolytic manganese particles.

[0041] In this embodiment, a rotating shaft 58 is connected to the middle position of the top of the grinding mill housing 51 through a bearing, and a fan blade 57 is installed at the lower end of the rotating shaft 58; the upper end of the rotating shaft 58 is connected to the driving motor 59 through a pulley and a belt.

[0042] By adopting the above technical solution, after the electrolytic manganese particles are ground into powder, the drive motor 59 drives the rotating shaft 58 to rotate through the cooperation of the pulley and the belt, and the fan blades 57 exhaust air from the interior of the mill housing 51. In addition, the negative pressure of the centrifugal separator 7 cooperates to facilitate the extraction of the powder into the centrifugal separator 7 for the collection of the electrolytic manganese powder.

[0043] The working principle of the utility model is as follows: when crushing electrolytic manganese, for larger pieces of electrolytic manganese, a jaw crusher 1 is used for preliminary crushing. Through the periodic movement of the movable jaw and the static jaw, the electrolytic manganese pieces entering the crushing chamber are subjected to forces such as squeezing and splitting, thereby crushing them into smaller pieces. The crushing ratio is large, and the large pieces of electrolytic manganese can be quickly crushed into medium-sized particles. Then, the crushed electrolytic manganese is transferred to the storage hopper 3 by the elevator 2, and then released to the belt conveyor 4 through the storage hopper 3. The belt conveyor 4 is used to transport the electrolytic manganese to the grinding mill 5 for further crushing the medium-sized electrolytic manganese.

[0044] The storage tank 10 is used to store small particles of electrolytic manganese, eliminating the crushing process of the jaw crusher 1. When the feed fan 6 is working, it can provide a negative pressure to the centrifugal separator 7, so that dust can be extracted from the mill 5. With the cooperation of the centrifugal separator 7, the separation of air and electrolytic manganese powder is achieved. Secondly, the air outlet end of the feed fan 6 blows air into the mill 5, and can form a wind force at the lower end of the discharge pipe 11, which can directly transport the small particles of electrolytic manganese into the mill 5.

[0045] When the feeding fan 6 conveys the electrolytic manganese particles into the feeding bottom shell 55, the grinding motor 54 drives the transmission shaft 50 to rotate, and the oblique scraper 53 scoops up the electrolytic manganese particles. Under the action of centrifugal force, the electrolytic manganese particles are thrown between the grinding roller assembly 52 and the grinding ring 56, thereby achieving grinding and crushing of the electrolytic manganese particles.

[0046] After the electrolytic manganese particles are ground into powder, the drive motor 59 drives the rotating shaft 58 to rotate through the cooperation of the pulley and the belt, and the fan blades 57 exhaust air into the inside of the grinding mill housing 51. In addition, the negative pressure of the centrifugal separator 7 facilitates the extraction of the powder into the centrifugal separator 7 for the collection of the electrolytic manganese powder.
