Description

Technical Field

[0001] This application relates to ferroalloy production technology, and more particularly to a ferroalloy product processing device. Background Technology

[0002] In the production of ferrosilicon alloys, after the molten alloy is cast and cooled, it needs to be crushed and screened to process the ferrosilicon alloy into the particle size required by the steel plant (generally 10mm-50mm).

[0003] Currently, to improve the processing efficiency of ferrosilicon alloy products, crushing and screening production lines are commonly used to process the ferrosilicon alloy. One existing ferroalloy product processing line includes a crusher, a screening machine, and a ton bag packaging machine. In operation, the ferrosilicon alloy is crushed by the crusher and then conveyed to the screening machine via conveyor I. The screening machine screens the crushed ferrosilicon alloy, separating out ferrosilicon alloy blocks that meet the requirements. These compliant ferrosilicon alloy blocks are then conveyed to the ton bag packaging machine via conveyor II for packaging.

[0004] However, when processing silicon-manganese alloy products, the crusher and screening machine in this ferroalloy product processing line are both semi-enclosed, resulting in a large amount of dust generation at these locations. Moreover, since the crusher and screening machine are set up separately, there are many dust leakage points. A significant amount of dust is generated at the feed point of the crusher, between the crusher and conveyor I, between conveyor I and the screening machine, and at each discharge port of the screening machine. To prevent dust, dust collection hoods need to be installed at these dust generation points. In addition, to ensure the dust collection effect at each dust collection point, high-power bag filters are also required. This not only results in a large number of dust collection hoods and high costs, but also in high energy consumption for high-power bag filters. Utility Model Content

[0005] This application provides a ferroalloy product processing device to solve the problems of existing ferroalloy product processing lines having a large number of dust hoods, high cost, and high energy consumption of bag filters when processing silicon-manganese alloy products.

[0006] This application provides a ferroalloy product processing device, including a box and a ton bag packaging machine. The upper end of the box is provided with a feeding hopper, one end of the box is provided with a temporary storage bin that is connected and sealed thereto, the outer wall of the box is provided with a conveying device that extends into the feeding hopper and has a closed structure, and the conveying device is connected and sealed to the temporary storage bin. The lower end of the box is sealed with a collection box.

[0007] The interior of the box is provided with a crushing structure located below the feed hopper and a vibrating mounting frame from top to bottom. The mounting frame is provided with screen plate I and screen plate II from top to bottom.

[0008] One end of the sieve plate I is connected to a material guiding structure that extends from the inside of the temporary storage bin to the inside of the conveying device, and one end of the sieve plate II is connected to a material guiding trough that extends into the inside of the temporary storage bin.

[0009] Below the temporary storage bin is a conveyor I for feeding materials to the ton bag packaging machine;

[0011] Optionally, the feeding hopper includes a hopper body that runs vertically through the top and bottom, and a dust cover. The dust cover is a hollow structure with openings at the bottom and one side, and the bottom of the dust cover is sealed to the top of one end of the hopper body.

[0012] The conveying device extends into the interior of the dust cover.

[0013] Optionally, the conveying device includes a conveying channel, which is a hollow structure with one end open. The open end of the conveying channel extends into the interior of the dust cover. The conveying channel is connected to and sealed with a temporary storage bin. The interior of the conveying channel is equipped with a conveyor II that can convey materials to the hopper.

[0014] The material guiding structure extends above the feed section of conveyor II.

[0015] Optionally, the material guiding structure includes a trough I, which is connected to a screen plate I and extends into the interior of a temporary storage bin. Below the trough I, there is a trough II located inside the temporary storage bin and distributed at an incline.

[0016] The trough II extends above the feed section of the conveyor II.

[0017] Optionally, the mounting frame is a hollow structure, and both sieve plate I and sieve plate II are installed in the hollow position of the mounting frame. The mounting frame is connected to the inner wall of the box through a spring assembly, and a vibrator is installed at the upper end of the mounting frame.

[0018] Optionally, the lower end of the box is sealed with a discharge valve, and the lower end of the discharge valve is connected to a sealing cover adapted to the collection box through a corrugated rubber telescopic tube. The sealing cover is connected to two electric push rods that can move up and down.

[0019] The ferroalloy product processing device provided in this application includes a feeding hopper at the top of a housing, a temporary storage bin at one end of the housing that is connected to and sealed thereto, a conveying device extending into the feeding hopper and forming a closed structure on the outer wall of the housing, and the conveying device being connected to and sealed to the temporary storage bin. A collection bin is sealed to the bottom of the housing. Inside the housing, from top to bottom, there is a crushing structure located below the feeding hopper and a vibrating mounting frame. The mounting frame has two screen plates, I and II, arranged from top to bottom. One end of screen plate I is connected to a guide structure extending from the inside of the temporary storage bin into the conveying device, and one end of screen plate II is connected to a guide structure extending into the temporary storage bin into the conveying device. The storage hopper has a guide chute, and below the temporary storage hopper is a conveyor I for feeding materials to the ton bag packaging machine. Dust collection hoods are installed at the feed hopper and between the temporary storage hopper and conveyor I. The dust collection hoods are connected to bag filters through dust collection pipes, so that when ferroalloy products are crushed and screened, dust only leaks out at the feed hopper and between the temporary storage hopper and conveyor I. Compared with existing ferroalloy product processing lines, this reduces the number of dust leakage points, thereby reducing the number of dust collection hoods and lowering dust control costs. Moreover, with fewer dust collection hoods, a lower-power bag filter can be used to ensure dust collection efficiency while also reducing energy consumption. Attached Figure Description

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0029] like Figures 1-6 As shown:

[0030] An embodiment of this application provides a ferroalloy product processing device, including a box body 1 and a ton bag packaging machine 2. A feed hopper 3 is fixed to the upper end of the box body 1, and a temporary storage chamber 4 is provided at one end of the box body 1 and is connected and sealed thereto. Specifically, the temporary storage chamber 4 includes a chamber body, which is integral with the box body 1, and a gate valve 5 is installed at the lower end of the chamber body.

[0031] The outer wall of the box 1 is equipped with a conveying device 6 that extends into the inside of the feed hopper 3 and has a closed structure. The conveying device 6 is connected to and sealed to the temporary storage bin 4.

[0032] The lower end of the box 1 is sealed with a collection box 9.

[0033] The interior of the housing 1 is provided with a crushing structure 10 located below the feed hopper 3 and a vibrating mounting frame 11 from top to bottom. The mounting frame 11 is provided with a screen plate I 12 and a screen plate II 13 from top to bottom. Specifically, the screen hole diameter of the screen plate I 12 is larger than that of the screen hole diameter of the screen plate II 13, and both the screen plate I 12 and the screen plate II 13 are inclined.

[0034] In this embodiment, the crushing structure 10 includes two symmetrically distributed crushing rollers with opposite rotation directions. The crushing rollers are rotatably connected to the housing 1 via bearings, and each crushing roller is connected to a motor via a belt drive mechanism.

[0035] One end of the sieve plate I 12 is connected to a material guiding structure extending from the inside of the temporary storage bin 4 to the inside of the conveying device 6, and one end of the sieve plate II 13 is connected to a material guiding trough 15 extending into the inside of the temporary storage bin 4.

[0036] Below the temporary storage bin 4 is a conveyor I16 for conveying materials to the ton bag packaging machine 2.

[0037] Dust collection hoods 17 are provided at the feeding hopper 3 and between the temporary storage bin 4 and the conveyor I 16. The dust collection hoods 17 are connected to a bag filter 19 through a dust collection pipe 18.

[0038] In this embodiment, a dust suction hood 17 is provided between the conveyor I 16 and the ton bag packaging machine 21, and the dust suction hood 17 is connected to the dust suction pipe 18.

[0039] In use, the cooled ferrosilicon manganese alloy is conveyed to the feed hopper 3 via a conveying device. The ferrosilicon manganese alloy in the feed hopper 3 enters the crushing structure 10 for crushing. The crushed ferrosilicon manganese alloy falls directly onto the screen plate I12. The screen plate I12 screens out the ferrosilicon manganese alloy particles that are too large. The oversized ferrosilicon manganese alloy particles flow along the screen plate I12 to the guide structure and then enter the conveying device 6. The conveying device 6 conveys the oversized ferrosilicon manganese alloy particles back to the feed hopper 3 for further crushing. The ferrosilicon manganese alloy particles that meet the particle size requirements and the oversized ferrosilicon manganese alloy particles exit from the screen plate I12. The material falls onto screen plate II13, which separates the silicon-manganese alloy particles that meet the required particle size. The silicon-manganese alloy particles that meet the required particle size flow along screen plate I12 and guide chute 15 into temporary storage bin 4 (the silicon-manganese alloy particles that meet the required particle size are temporarily stored in temporary storage bin 4 to provide a stable material supply for conveyor I16). The silicon-manganese alloy particles that are too small fall from screen plate II13 to the bottom of box 1 and enter collection bin 9. Collection bin 9 collects the silicon-manganese alloy particles that are too small. The silicon-manganese alloy particles in temporary storage bin 4 fall onto conveyor I16 and are transported by conveyor I16 to ton bag packaging machine 2 for packaging.

[0040] While processing the silicon-manganese alloy, the bag filter 19 is activated. The bag filter 19 sucks up dust from the feed hopper 3, the temporary storage bin 4 between the conveyor I 16, and the ton bag packaging machine 2 through the suction pipe 18 and the suction hood 17, preventing dust from spreading into the workshop and affecting the workshop environment.

[0041] The ferroalloy product processing device provided in this embodiment crushes and screens the ferrosilicon manganese alloy within the housing 1. Dust generated during crushing and screening processes will not leak into the workshop. With the enclosed conveyor 6 and temporary storage bin 4 sealed and connected, dust leakage only occurs at the feed hopper 3 during the process of large-sized ferrosilicon manganese alloy particles moving from the screen 1 to the feed hopper 3. With the housing 1 and temporary storage bin 4 connected and sealed, dust generated during the process of ferrosilicon manganese alloy particles of the appropriate size moving from the screen plate II 13 to the temporary storage bin 4 will not leak into the workshop. The collection bin 9... After being sealed to the lower end of the housing 1, the dust generated during the process of the silicon-manganese alloy housing 1 to the collection box 9 with excessively small particles will not leak into the workshop. Therefore, when the ferroalloy products are crushed and screened, dust will only leak from the feed hopper 3 and the temporary storage bin 4 between the feed hopper 16 and the conveyor I. Compared with the existing ferroalloy product processing line, the number of dust leakage points can be reduced, thereby reducing the number of dust collection hoods 17 and reducing dust prevention costs. Moreover, after reducing the number of dust collection hoods 17, the dust collection effect can be guaranteed by using a bag filter 19 with lower power, while also reducing energy consumption.

[0042] In some embodiments of this application, the feed hopper 3 includes a hopper body 301 that runs vertically through the hopper and a dust cover 302. The dust cover 302 is a hollow structure with openings at the lower end and one side end. The lower end of the dust cover 302 is sealed to the top of one end of the hopper body 301. The conveying device 6 extends into the interior of the dust cover 302.

[0043] In this embodiment, the dust cover 302 has openings at the front and lower ends, so that the dust generated at the feed hopper 3 can only be discharged from the hopper body 301 at the front end of the dust cover 302. The dust suction cover 17 at the feed hopper 3 is located at the right end of the feed hopper 3 and at the front end of the dust cover 302, which facilitates the suction of the dust generated at the feed hopper 3.

[0044] In some embodiments of this application, the conveying device 6 includes a conveying channel 601, which is a hollow structure with one open end, and the open end of the conveying channel 601 extends into the interior of the dust cover 302. Specifically, the opening of the conveying channel 601 penetrates through the right end of the dust cover and is sealed and fixedly connected to the right end of the dust cover.

[0045] The conveying channel 601 is connected to and sealed to the temporary storage chamber 4. Specifically, the front end of the conveying channel 601 has a connecting hole I7, and the rear end of the temporary storage chamber 4 has a connecting hole II8. The edges of the connecting hole I7 and the edges of the connecting hole II8 are sealed and fixedly connected.

[0046] The conveying channel 601 is equipped with a conveyor II 602 that can convey materials to the bucket 301;

[0047] The material guiding structure extends above the feed section of conveyor II 602. Specifically, the material guiding structure extends from connecting holes I 7 and II 8 above the feed section of conveyor II 602.

[0048] During use, excessively large silicon-manganese alloy particles fall from the guide structure onto conveyor II 602, which then transports them into feed hopper 3.

[0049] In some embodiments of this application, the material guiding structure includes a trough I, which is fixedly connected to a screen plate I12 and extends into the interior of a temporary storage bin 4. Below the trough I, a trough II1402 is located inside the temporary storage bin 4 and is inclined. The trough II1402 extends above the feed section of the conveyor II602. The trough II1402 passes through connecting holes I7 and II8 and extends above the feed section of the conveyor II602.

[0050] During use, excessively large silicon-manganese alloy particles flow from sieve plate I12 into tank I, then from tank I into tank II1402, and finally from tank II1402 into the conveyor.

[0051] In some embodiments of this application, the mounting frame 11 is a hollow structure, and the sieve plate I 12 and sieve plate II 13 are both fixedly installed in the hollow position of the mounting frame 11. The mounting frame 11 is connected to the inner wall of the box 1 through the spring assembly 20, and a vibrator 21 is installed at the upper end of the mounting frame 11.

[0052] When in use, after the vibrator 21 is working, the mounting frame 11 vibrates under the action of the spring assembly 20, which in turn drives the screen plate I 12 and screen plate II 13 to vibrate. The vibration of the screen plate I 12 and screen plate II 13 can improve the screening effect of silicon-manganese alloy.

[0053] In some embodiments of this application, a discharge valve 22 is sealed to the lower end of the housing 1, and a sealing cover 24 adapted to the collection box 9 is connected to the lower end of the discharge valve 22 via a corrugated rubber telescopic tube 23. Specifically, the upper end of the corrugated rubber telescopic tube is sealed to the discharge valve 22, and the lower end of the corrugated rubber telescopic tube is sealed to the sealing cover 24.

[0054] The sealing cover 24 is connected to two electric push rods 25 that can move up and down. The electric push rods 25 are fixed to the lower end of the housing.

[0055] In use, the collection box 9 is placed under the sealing cover 24. Then, the two electric push rods 25 extend synchronously, the sealing cover 24 moves down, and after the sealing cover 24 presses tightly against the upper end of the collection box 9, the downward movement of the sealing cover 24 is stopped, and the discharge valve 22 is opened. The excessively small-sized silicon-manganese alloy falls from the box 1 into the collection box 9. After the collection box 9 is full of excessively small-sized silicon-manganese alloy, the discharge valve 22 is closed. At this time, the excessively small-sized silicon-manganese alloy falling from the sieve plate II 13 is temporarily stored at the bottom of the box 1. After the dust generated between the collection box 9 and the sealing cover 24 settles, the sealing cover 24 is moved up, and then the collection box 9 is transferred to the storage warehouse. Finally, the collection box 9 is placed under the sealing cover 24 again, and the sealing cover 24 presses tightly against the upper end of the collection box 9. The discharge valve 22 is opened to continue collecting excessively small-sized silicon-manganese alloy.

[0056] In this embodiment, the discharge valve 22 is a slide gate valve. The collection box 9 is transported by forklift.

[0057] In the embodiments of this application, both conveyor I16 and the conveyor are belt conveyors.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
