Description

Technical Field

[0001] This utility model relates to the field of manganese alloy pulverization technology, specifically to a pulverization device for developing manganese alloy additives. Background Technology

[0002] Manganese additives are typically composed of manganese and other metallic elements, and the composition varies among different manganese additives. Common manganese additives include aluminum-manganese alloys, silicon-manganese alloys, ferromanganese alloys, and ferromanganese alloys, each with different applications in various fields. Manganese additives can improve the properties of metallic materials, mainly by increasing hardness and strength, improving wear resistance, improving corrosion resistance, and promoting grain refinement.

[0003] As disclosed in Publication No. CN207402108U, a superalloy powder pulverizing device includes a crushing body, which includes a crushing base. The crushing base has a groove-shaped structure with protrusions on both sides and a concave center. Rotating shafts are supported on both sides of the crushing base. A crushing cylinder, a transition cylinder, and a discharge cylinder are provided in the middle of the crushing base and are hinged to the rotating shafts and connected in sequence. A drive pulley is connected to one end of the rotating shaft. An inclined discharge port is connected to one side of the crushing cylinder. A feed hopper is connected above the inclined discharge port. A discharge pipe is connected to the side of the discharge cylinder. The sequentially connected crushing cylinder, transition cylinder, and discharge cylinder can continuously discharge the pulverized alloy powder, thus improving efficiency.

[0004] Existing technologies have limitations. First, sieving is not possible during the crushing process, resulting in uneven particle size after crushing, which affects the efficient use of subsequent alloy additives. Second, dust or fine debris generated during crushing can easily mix into the surrounding air environment, causing PM particulate air pollution. Therefore, it is necessary to recycle the dust particles to improve the clean preparation of alloy additives.

[0005] Therefore, it is necessary to develop a crushing device for manganese alloy additives. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a manganese alloy additive development and pulverizing device, which aims to solve the technical problems mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a manganese alloy additive development and pulverizing device, comprising two-stage pulverizing equipment, an outlet pipe I, and an outlet pipe II. Manganese alloy particles crushed by the first-stage pulverizing equipment are conveyed to the second-stage pulverizing equipment via a guide plate. The manganese alloy particles crushed by the second-stage pulverizing equipment are then conveyed to a storage tank via the guide plate. The particles crushed by both stages are screened by the guide plate and then conveyed to a conveyor belt for recycling via a support plate. One side of the pulverizing equipment is configured as a dust outlet, with a filter plate inserted inside. The dust outlet's outlet direction is configured as a conical-cylindrical outlet pipe I. The larger side of outlet pipe I has its inlet end connected to the outlet end of the dust outlet. The smaller side of outlet pipe I has its outlet end connected to the inlet end of outlet pipe II, which is configured as a cylindrical structure. The outlet end of outlet pipe II is connected to a pump, and the outlet end of the pump is connected to a dust filter box.

[0008] Preferably, the side of the dust outlet is provided with an inlet, and the upper and lower sides of the inlet are provided with sliding grooves. The upper and lower sides of the filter plate are provided with slider protrusions, which are slidably installed with the sliding grooves to limit the installation of the filter plate.

[0009] Preferably, the bottom of the crushing equipment is set as the discharge port, and baffles are set on both sides of the bottom of the discharge port, with guide plates set between the baffles.

[0010] Preferably, the middle part of the guide plate is provided with filter holes for screening the crushed manganese alloy particles.

[0011] Preferably, a support plate is provided on one side surface of the guide plate at the bottom of the filter hole.

[0012] Preferably, the width of the support plate is greater than the width of the guide plate.

[0013] In summary, this utility model provides a manganese alloy additive development and pulverizing device. Qualified particles screened out by a guide plate are further pulverized by a second-stage pulverizing device. The particles processed by the second-stage pulverizing device are then screened again by the guide plate, and the screened qualified particles are conveyed to a storage tank. Waste particles are conveyed by a support plate to a conveyor belt for recycling, achieving graded pulverization and waste particle screening and recycling, resulting in uniform particle size of the pulverized manganese alloy additive. Dust particles are conveyed from outlet pipe one to outlet pipe two, and then pumped into a dust filter box for dust treatment and filtration. The dust filter box preferably uses a composite fiber cartridge dust collector to achieve high filtration efficiency and good wear resistance.

[0014] The dust particles inside the crushing equipment are drawn and recovered. Due to the conical structure of the outlet pipe, a siphon structure is realized to accelerate the extraction and recovery of dust particles, thereby improving the efficiency of dust recovery and further improving the uniformity of particle size in the development of manganese alloy additives.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown:

[0021] This utility model relates to a manganese alloy additive development and pulverizing device, comprising a two-stage pulverizing device 1, an outlet pipe 1 2, and an outlet pipe 2 3. The manganese alloy particles crushed by the first-stage pulverizing device 21 are conveyed to the second-stage pulverizing device 22 via a guide plate 4. The manganese alloy particles crushed by the second-stage pulverizing device 22 are conveyed to a storage tank 5 via the guide plate 4. The particles crushed by the two-stage pulverizing device 1 are screened by the guide plate 4 and then conveyed to a conveyor belt 7 for recycling via a support plate 6. One side of the pulverizing device 1 is configured as a dust outlet 11, and a filter plate 12 is inserted and installed inside the dust outlet 11. The outlet direction of the dust outlet 11 is configured as a conical-cylindrical outlet pipe 1 2. The inlet end of the larger side of the outlet pipe 1 2 is connected to the outlet end of the dust outlet 11, and the smaller side of the outlet pipe 1 2 is configured as the outlet end, which is connected to the inlet end of the outlet pipe 2 3. The outlet pipe 2 3 is configured as a cylindrical structure. The outlet end of the outlet pipe 2 3 is connected to a pump device 13, and the outlet end of the pump device 13 is connected to a dust filter box 14.

[0022] To address the lack of screening and dust collection technologies in existing technologies, this utility model patent adopts the following technical structure: a two-stage crushing device 1 is used to crush manganese alloy. The first-stage crushing device 21 performs pre-crushing, and the large particles after crushing are conveyed to the second-stage crushing device 22 by a guide plate 4. The waste particles screened by the guide plate 4 are conveyed to the conveyor belt 7 for recycling by a support plate 6 at its bottom. The qualified particles screened by the guide plate 4 are further crushed by the second-stage crushing device 22. The particles processed by the second-stage crushing device 22 are screened by the guide plate 4, and the qualified particles are conveyed to the storage tank 5 by the guide plate 4. The waste particles screened are conveyed to the conveyor belt 7 for recycling by the support plate 6. This achieves graded crushing and waste particle screening and recycling, resulting in uniform particle size of the crushed manganese alloy additive.

[0023] By setting a dust outlet 11 on one side of the crushing equipment 1, and inserting a filter plate 12 inside the dust outlet 11, large particles of manganese alloy are filtered. After the fine dust particles are screened by the filter plate 12, air is drawn in by the pump equipment 13. The dust particles are transported from the outlet pipe 1 to the outlet pipe 2, and then drawn into the dust filter box 14 by the pump equipment 13 for dust treatment and filtration. The dust filter box 14 is preferably a composite fiber cartridge dust collector to achieve high filtration efficiency and good wear resistance.

[0024] The key technical feature is that outlet pipe 2 has a conical structure. The larger diameter end of outlet pipe 2 connects to the outlet end of dust outlet 11, while the smaller diameter end connects to the inlet end of outlet pipe 3. Outlet pipe 3 has a cylindrical structure. This design creates a negative pressure environment inside outlet pipes 2 and 3 during the pumping process, enabling the extraction and recovery of dust particles from the crushing equipment 1. The conical structure of outlet pipe 2 utilizes a siphon mechanism to accelerate the extraction and recovery of dust particles, thereby improving dust recovery efficiency and further enhancing the uniformity of the manganese alloy additive particle size.

[0025] In at least one embodiment, in order to achieve the detachable replacement of the filter plate 12 and the dust outlet 11, as well as the snap-fit ​​installation and fixation, an insertion port 15 is opened on the side of the dust outlet 11. Sliding grooves 16 are opened on both the upper and lower sides of the insertion port 15. Sliding slider protrusions 17 are provided on both the upper and lower sides of the filter plate 12. The sliding slider protrusions 17 are slidably installed with the sliding grooves 16 to limit the installation of the filter plate 12.

[0026] In at least one implementation, in order to prevent leakage of the crushed particles, a discharge port 211 is set at the bottom of the crushing equipment 1, and baffles 222 are set on both sides of the bottom of the discharge port 211, with a guide plate 4 between the baffles 222.

[0027] In at least one implementation, in order to achieve the screening of the crushed particulate material, a filter hole 23 is provided in the middle of the guide plate 4 to screen the crushed manganese alloy particles.

[0028] In at least one implementation, in order to achieve the sieving and recycling of crushed particles, a support plate 6 is provided on one side surface of the guide plate 4 located at the bottom of the filter hole 23; the width of the support plate 6 is greater than the width of the guide plate 4.

[0029] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
