Description

Technical Field

[0001] This utility model relates to the field of ore pretreatment, specifically to a manganese ball production and forming system. Background Technology

[0002] Manganese spheres, a product playing a crucial role in the industrial field, are made from manganese-bearing ore through specific processes. Their main component contains varying proportions of manganese, and may also contain other associated elements such as iron, silicon, and phosphorus. Manganese spheres are typically spherical, possessing a certain degree of hardness and density, which allows them to adapt to various industrial production environments. Due to their excellent reducing and alloying properties, manganese spheres have extremely important applications in metallurgy, chemical engineering, and other fields.

[0003] In the metallurgical industry, manganese spheres are an important deoxidizer and alloying additive in steelmaking. Adding manganese spheres during the steelmaking process effectively removes oxygen from molten steel, improving its quality and performance. Simultaneously, manganese can undergo alloying reactions with other elements in steel, improving its strength, toughness, wear resistance, and many other properties, making it widely used in the production of various types of construction steel and machinery manufacturing steel. In the chemical industry, manganese spheres are also frequently used as a raw material for catalysts. The manganese they contain can act as a catalyst in some chemical reactions, accelerating the reaction process and improving the production efficiency and quality of chemical products. For example, they are used in certain organic synthesis reactions and catalytic reactions in waste gas treatment.

[0004] In the production of manganese balls, the raw materials for making manganese balls are first mixed with adhesive to form a mixed adhesive powder, which is then fed into a briquetting machine to be pressed into manganese balls. The manganese balls discharged from the briquetting machine usually contain poorly formed manganese balls and unformed raw material particles, requiring screening to separate the poorly formed manganese balls and unformed raw material particles. Existing technology discloses a coal briquetting device and production line, which screens the formed coal balls and then transports the screened unformed coal balls to a coal briquetting machine for further pressing.

[0005] After careful research, the inventors discovered the following problems when the production line was used in the molding of manganese balls: when the mixed raw materials, unformed manganese balls, and unformed raw material particles were transported on the conveyor belt, they were very likely to fall off the conveyor belt due to their own characteristics and vibrations during the transport process, which generated dust. This not only caused waste of raw materials, but also may pollute the production environment and even affect the normal operation of subsequent production processes. Utility Model Content

[0006] The present invention aims to provide a manganese ball production and molding system to solve the problem that raw materials are easily dropped during the transport of raw materials for making manganese balls in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] The manganese ball production and forming system includes a feeding hopper and a briquetting machine. A raw material conveyor belt connects the inlet of the feeding hopper and the briquetting machine. A screening mechanism is installed at the outlet of the briquetting machine. A return conveyor belt connects the screening mechanism and the raw material conveyor belt. The surfaces of the raw material conveyor belt and the return conveyor belt are arc-shaped with a downward concave center. The screening mechanism includes a downwardly inclined screen that is connected to the outlet of the briquetting machine. Screen baffles are installed on both sides of the screen, and a vibrating motor is installed on the side of the screen. The system also includes a dust removal mechanism, which includes a screening dust removal hood installed above the screen. The screening dust removal hood is connected to a screening dust removal pipe, which is connected to a dust collector. Dust curtains are connected around the screening dust removal hood, and the dust curtains cover the edges of the screen.

[0009] Preferably, as an improvement, the raw material conveyor belt is inclined, with the discharge end of the raw material conveyor belt at the high end. The return material conveyor belt is also inclined and in the opposite direction to the inclination of the raw material conveyor belt, with the discharge end of the return material conveyor belt at the high end. The raw material conveyor belt and the return material conveyor belt are respectively set on both sides of the briquetting machine. The dust removal mechanism also includes a return material dust removal hood set above the high end of the return material conveyor belt. The return material dust removal hood is connected to a return material dust removal pipe, which is connected to a dust collector.

[0010] Preferably, as an improvement, the dust removal mechanism further includes a conveyor dust removal hood disposed above the connection between the raw material conveyor belt and the return material conveyor belt, the conveyor dust removal hood being connected to a conveyor dust removal pipe, and the conveyor dust removal pipe being connected to a dust collector.

[0011] Preferably, as an improvement, the high end of the return conveyor belt is connected to a guide hopper, the guide hopper is inclined and the free end is downward, and a guide trough is inclined below the guide hopper, the high end of the guide trough is located below the guide hopper, and the bottom end of the guide trough is connected to the raw material conveyor belt.

[0012] Preferably, as an improvement, vertical material baffles are provided around the feed end of the material conveyor belt.

[0013] Preferably, as an improvement, both the raw material conveyor belt and the return material conveyor belt are provided with anti-slip structures.

[0014] Preferably, as an improvement, the anti-slip structure is an anti-slip ridge, anti-slip bump, or anti-slip groove.

[0015] Preferably, as an improvement, the two sides of the guide hopper are rotatably connected to the frame of the return conveyor belt by bolts, and the bolts are threaded with locking nuts.

[0016] The principles and beneficial effects of this solution are as follows:

[0017] 1. After mixing, the manganese sphere raw material is fed into the feed hopper. The feed hopper continuously conveys the raw material to an inclined material conveyor belt, which then transports it to a briquetting machine to be pressed into manganese spheres. The formed manganese spheres roll off the briquetting machine outlet onto a downward-sloping screen for sieving. Screen baffles on both sides of the screen prevent the manganese spheres from rolling off. Dust generated during sieving is collected by a screening dust hood and dust curtain, and sent to a dust collector through a screening dust removal pipe. Qualified manganese spheres are collected at the bottom of the screen, while broken manganese spheres or powder fall below the screen and are transported back to the raw material conveyor belt via a return conveyor belt, then fed back into the briquetting machine for pressing.

[0018] 2. In this solution, the surfaces of the raw material conveyor belt and the return material conveyor belt are V-shaped. Compared with ordinary flat conveyor belts, the V-shaped structure can better restrict the position of mixed raw materials, unformed manganese balls and unformed raw material particles on the conveyor belt, so that the materials are concentrated in the groove of the conveyor belt, which greatly reduces the possibility of materials falling off the conveyor belt due to vibration, inertia and other factors, and effectively solves the problem of raw materials easily falling off during the conveying process in the prior art.

[0019] 3. In addition, vertical raw material baffles are installed around the feed end of the raw material conveyor belt to prevent the material from scattering in all directions due to feeding impact when it first enters the conveyor belt, further reducing the occurrence of raw material falling.

[0020] 4. The surfaces of the raw material conveyor belt and the return material conveyor belt are equipped with anti-slip structures, such as anti-slip strips, anti-slip bumps, or anti-slip grooves. These anti-slip structures increase the friction between the conveyor belt surface and the material, making the material more stable during transmission and less prone to slipping and falling, thus playing a supporting role in solving the problem of raw material falling.

[0021] 5. The screening dust hood installed above the screening mechanism is connected to the screening dust removal pipe and the dust collector, and the screening dust removal hood is surrounded by dust-blocking curtains that cover the edges of the screen. During the manganese ball screening process, the dust generated can be effectively collected by the screening dust removal hood and transported to the dust collector for treatment through the screening dust removal pipe. The dust-blocking curtains further prevent dust from escaping, greatly reducing dust pollution caused by screening in the workshop, improving the workshop working environment, and solving the problem of dust generation during finished product screening mentioned in the background technology.

[0022] 6. In addition, a return material dust hood is installed above the high end of the return material conveyor belt, which connects the return material dust collection pipe to the dust collector. When the crushed manganese balls or powder are conveyed by the return material conveyor belt, the dust generated during the conveying process can be collected by the return material dust hood and sent to the dust collector, reducing dust pollution during the return material conveying process and further improving the dust removal effect of the entire production system.

[0023] 7. Furthermore, a dust collection hood is installed above the connection between the raw material conveyor belt and the return material conveyor belt, connecting the dust collection pipe to the dust collector. The dust generated here is mainly due to vibrations that may occur during the mixing and transmission of the return material and the raw material. The dust collection hood can collect this dust in a timely manner, preventing it from spreading into the workshop and effectively reducing dust pollution at the connection point.

[0024] 8. The design of the raw material conveyor belt and return material conveyor belt, with their discharge ends at the higher end and in opposite directions, and positioned on both sides of the briquetting machine, offers significant advantages in space utilization. This layout cleverly utilizes the vertical space of the workshop, avoiding a large-area extension of the conveyor belt on the horizontal plane, thus greatly reducing the footprint of the entire production system. Simultaneously, the dual-sided distribution design allows for more compact material flow around the briquetting machine, with close connections between different conveying links, reducing the detours of materials within the workshop. Overall, this creates a compact and rationally laid-out production system, maximizing the efficient use of workshop space.

[0025] 9. The installation of guide hoppers and guide troughs can guide the material on the return conveyor belt to the raw material conveyor belt more accurately and stably, avoiding spillage of material during the transfer process. It also optimizes the process of remixing return material with raw material and improves the continuity of production.

[0026] 10. The guide hopper is rotatably connected to the frame of the return conveyor belt on both sides by bolts, and the bolts are threaded with locking nuts. This design allows the tilt angle of the guide hopper to be adjusted according to actual production conditions to adapt to different material flow rates and conveying requirements, thus improving the flexibility and applicability of the equipment.

[0030] The following detailed description illustrates the specific implementation method:

[0031] The reference numerals in the accompanying drawings of the instruction manual include: feed hopper 1, raw material baffle 2, raw material conveyor belt 3, conveyor wheel 31, belt 32, anti-slip convex strip 321, frame 33, return conveyor belt 4, guide hopper 41, guide trough 42, return dust hood 5, return dust pipe 51, conveying dust pipe 52, conveying dust hood 53, screening dust hood 54, screening dust pipe 55, dust curtain 56, briquetting machine 6, screen 7, and screen baffle 71.

[0032] Example 1:

[0033] like Figure 1 As shown, the manganese briquette production and forming system includes a feeding hopper 1 and a briquetting machine 6, which is a double-roller briquetting machine 6. An inclined raw material conveyor belt 3 connects the bottom of the feeding hopper 1 and the inlet of the briquetting machine 6. The feeding end of the raw material conveyor belt 3 is at the bottom and below the feeding hopper 1, while the discharging end is at the top and connected to the inlet of the briquetting machine 6. Vertical raw material baffles 2 are arranged around the feeding end of the raw material conveyor belt 3.

[0034] Combination Figure 2 As shown, a screening mechanism is provided at the outlet of the briquetting machine 6. The screening mechanism includes a downwardly inclined screen 7, the high end of which is connected to the outlet of the briquetting machine 6. Vertical screen baffles 71 are welded to both sides of the screen 7, and a vibrating motor (not shown in the figure) is installed on the side of the screen 7. A return conveyor belt 4 is connected between the screening mechanism and the raw material conveyor belt 3. The return conveyor belt 4 is also inclined and in the opposite direction to the inclination of the raw material conveyor belt 3, that is, the discharge end of the return conveyor belt 4 is at the high end. The raw material conveyor belt 3 and the return conveyor belt 4 are respectively set on both sides of the briquetting machine 6 to save space. A guide hopper 41 is connected to the high end of the return conveyor belt 4. The guide hopper 41 is inclined and the free end is downward. A guide trough 42 is inclined below the guide hopper 41. The high end of the guide trough 42 is located below the guide hopper 41, and the bottom end of the guide trough 42 is connected to the raw material conveyor belt 3.

[0035] gather Figure 3 As shown, the surfaces of the raw material conveyor belt 3 and the return material conveyor belt 4 are arc-shaped with a downward concave center. Specifically, both the raw material conveyor belt 3 and the return material conveyor belt 4 include a frame 33, conveyor wheels 31, and a belt 32. In this embodiment, the belts 32 of both the raw material conveyor belt 3 and the return material conveyor belt 4 are made of soft belts 32. Two rows of conveyor wheels 31 are arranged along the conveying direction, and both rows of conveyor wheels 31 are inclined towards the center, so that when the belt 32 is tensioned on the conveyor wheels 31, it forms an arc-shaped concave center to collect the raw material in the groove of the belt 32 and prevent the raw material from falling. The surfaces of both the raw material conveyor belt 3 and the return material conveyor belt 4 are provided with anti-slip structures. In this embodiment, the anti-slip structure is an anti-slip protrusion 321 integrally formed on the belt surface. In other embodiments, the anti-slip structure can also be an anti-slip protrusion or an anti-slip groove integrally formed on the belt surface.

[0036] This embodiment also includes a dust removal mechanism, comprising a screening dust removal hood 54 installed above the screen 7, a screening dust removal pipe 55 connected to the screening dust removal hood 54, and a dust collector, which is a bag filter dust collector. Dust-blocking curtains 56 are connected around the screening dust removal hood 54, covering the edges of the screen 7. The dust removal mechanism also includes a return material dust removal hood 5 installed above the high end of the return material conveyor belt 4, connected to a return material dust removal pipe 51, which is connected to the dust collector. The dust removal mechanism also includes a transmission dust removal hood 53 installed above the connection between the raw material conveyor belt 3 and the return material conveyor belt 4, connected to a transmission dust removal pipe 52, which is connected to the dust collector.

[0037] In practical application, the mixed manganese sphere raw material is fed into the feed hopper 1, where it is stored and continuously fed onto the raw material conveyor belt 3. The raw material conveyor belt 3 then transports the material to the briquetting machine 6 to be pressed into manganese spheres. After pressing, the manganese spheres are discharged from the outlet of the briquetting machine 6 onto an inclined screen 7 for sieving. Qualified manganese spheres fall along the screen 7 and are collected, while unqualified manganese spheres or unformed granular raw materials fall below the screen 7 and are transported via the return conveyor belt 4. They are then conveyed through the guide hopper 41 and guide trough 42 back onto the raw material conveyor belt 3, and finally transported back to the briquetting machine 6 for pressing.

[0038] Dust generated during the screening process is adsorbed into the dust collector by the screening dust hood 54 and screening dust pipe 55. Dust is easily generated when the recycled material falls from the high end of the return conveyor belt 4 into the guide chute 42; this dust is removed by the return dust hood 5 and return dust pipe 51. Dust is also easily generated when the recycled material falls from the guide chute 42 onto the raw material conveyor belt 3; this dust is removed by the conveyor dust hood 53 and conveyor dust pipe 52.

[0039] Example 2:

[0040] The difference between this embodiment and Embodiment 1 is that the guide hopper 41 is rotatably connected to the frame 33 of the return conveyor belt 4 on both sides by bolts, and locking nuts are threaded onto the bolts. With this configuration, the tilt angle of the guide hopper 41 can be adjusted by loosening the locking bolts as needed, and then locked in place by tightening the locking bolts.
