Description

Technical Field

[0001] This invention relates to the field of nickel-iron production technology, and in particular to a feeding and screening device for nickel-iron production. Background Technology

[0002] As a core raw material for stainless steel production, ferronickel requires several key processes, including raw material pretreatment, smelting, and refining. The feeding and grading of raw materials directly impact subsequent smelting efficiency, product quality, and energy consumption control. In the raw material processing stage of ferronickel production, ferronickel ore and other raw materials often contain impurities of varying particle sizes. Directly feeding these into the smelting furnace can lead to uneven reactions within the furnace, reduced nickel recovery, and potentially equipment malfunctions due to the accumulation of large impurities, increasing production and maintenance costs.

[0003] Chinese patent CN214383541U discloses a feeding mechanism for nickel-iron production. The device's first rotating shaft allows for easy control of the amount of material entering the feeding cavity. The spiral block continuously conveys the material upwards to achieve a continuous feeding effect. The device is simple and can effectively control the material feeding. However, the material tends to accumulate after entering the feeding cavity, causing blockage at the first discharge port. Moreover, some wet, clumped, or large-shaped nickel-iron materials are prone to jamming in the device, affecting the normal operation of the equipment. Therefore, a feeding and screening device for nickel-iron production is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding and screening device for nickel-iron production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A feeding and screening device for nickel-iron production includes a base plate, a support frame mounted on the base plate, a feeding hopper mounted on the top of the support frame, a screening component on one side of the feeding hopper, multiple support rods on the outer side of the screening component, a fixing plate mounted on the support rods, a second motor mounted on the fixing plate, a housing mounted on one side of the screening component, a rotating disk rotatably connected inside the housing, and a second conveyor belt mounted on the bottom side of the housing.

[0006] Preferably, multiple support frames are provided, and the multiple support frames are vertically arranged and installed on the top surface of the base plate. The feeding hopper is installed between the tops of the multiple support frames, and an electrically driven and controlled first conveyor belt is installed inside the bottom side of the feeding hopper.

[0007] Preferably, the bottom ends of the support rods are all fixedly installed on the top surface of the base plate, and multiple pressure blocks are provided on the outer side of the screening component. Each pressure block has a through hole, and the multiple pressure blocks are respectively connected to the outer side of the multiple support rods. Each support rod is welded and installed with a fixing plate, which is located on the bottom side of the pressure block. A first spring is connected between the pressure block and the fixing plate, and the screening component is movably connected to the outer side of the support rod.

[0008] Preferably, there are two fixing plates, which are horizontally installed between the support rods on one side. Each fixing plate is equipped with a second motor, and an eccentric disc is connected to the output end of each second motor. Both sides of the screening component are equipped with abutment wheels, and the eccentric disc is connected to the bottom side of the abutment wheels.

[0009] Preferably, an upper screen plate and a lower screen plate are installed obliquely between the inner walls of the screening component. Both the upper and lower screen plates are provided with screen holes. The diameter of the screen holes in the upper screen plate is larger than that in the lower screen plate. A feeding receiving plate is installed on one side of both the upper and lower screen plates. The bottom side of the lower screen plate corresponds to the position of the second conveyor belt, and a baffle is installed between the two.

[0010] Preferably, bases are installed on both sides of the housing, and the bases are fixedly installed on the bottom plate. An outward opening is installed at the inlet of the housing, and the position of the outward opening corresponds to the position of the unloading plate. A drive shaft is rotatably connected between the inner walls of the housing, and the rotary disk is installed on the outside of the drive shaft. A unloading port is opened on the bottom side of the housing, and the position of the unloading port corresponds to the position of the second conveyor belt, and a baffle is also provided between them.

[0011] Preferably, a drive wheel is mounted on the outer end of the drive shaft, and a first motor is also provided on the base plate, with a synchronous drive belt connecting the output end of the first motor and the drive wheel.

[0012] The beneficial effects of this invention are: This solution facilitates continuous material transport through the installation of a feeding hopper and a first conveyor belt. The rotation of the second motor allows for easy control of the screen components to continuously vibrate up and down. The two screen plates facilitate multiple filtrations of the material, and the rotating disc can break up large volumes of material, thus enabling continued feeding.

[0013] This solution reduces the possibility of material blockage in the device during the nickel-iron feeding and conveying process, reduces the possibility of material forming lumps or being too large to handle, improves the device's screening effect on materials before feeding, can separate materials to reduce the possibility of blockage, and also improves the device's ability to break up large-volume materials, thus enabling them to continue feeding without the need for secondary processing.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0017] Example: Refer to Figure 1-5 A feeding and screening device for nickel-iron production includes a base plate 1, a support frame 2 mounted on the base plate 1, a feeding hopper 3 mounted on the top of the support frame 2, a screening component 7 on one side of the feeding hopper 3, multiple support rods 11 on the outer side of the screening component 7, a fixing plate 23 mounted on the support rods 11, a second motor 13 mounted on the fixing plate 23, a housing 8 mounted on one side of the screening component 7, a rotating disk 16 rotatably connected inside the housing 8, a second conveyor belt 10 also mounted on the bottom side of the housing 8, multiple support frames 2 are provided, all of which are vertically arranged and mounted on the top surface of the base plate 1, the feeding hopper 3 is installed between the tops of the multiple support frames 2, and an electrically driven first conveyor belt 4 is installed inside the bottom side of the feeding hopper 3 to continuously convey the material forward for screening.

[0018] Specifically, the bottom ends of the support rods 11 are all fixedly installed on the top surface of the base plate 1. Multiple pressure blocks are provided on the outer side of the screening component 7. Each pressure block has a through hole. The multiple pressure blocks are respectively connected to the outer side of the multiple support rods 11. Fixing plates are welded and installed on the support rods 11. The fixing plates are located on the bottom side of the pressure blocks. A first spring 19 is connected between the pressure blocks and the fixing plates. The screening component 7 is movably connected to the outer side of the support rods 11.

[0019] Furthermore, there are two fixing plates 23, which are horizontally installed between the support rods 11 on one side. A second motor 13 is installed on each fixing plate 23, and an eccentric disk 14 is connected to the output end of each second motor 13. Abutting wheels 5 are installed on both sides of the screening component 7, and the eccentric disk 14 is connected to the bottom side of the abutting wheel 5.

[0020] Furthermore, an upper screen plate 6 and a lower screen plate 22 are installed obliquely between the inner walls of the screening component 7. Screen holes are opened on both the upper screen plate 6 and the lower screen plate 22. The diameter of the screen holes in the upper screen plate 6 is larger than the diameter of the screen holes in the lower screen plate 22, thereby achieving the effect of screening the material twice. A discharge receiving plate 21 is installed on one side of both the upper screen plate 6 and the lower screen plate 22. The bottom side of the lower screen plate 22 corresponds to the position of the second conveyor belt 10, and a baffle is installed between the two to reduce the possibility of leakage during the material falling.

[0021] In this embodiment, bases 12 are installed on both sides of the housing 8, and the bases 12 are fixedly installed on the base plate 1. An outward opening 17 is installed at the inlet of the housing 8, and the position of the outward opening 17 corresponds to the position of the unloading plate 21. A drive shaft 15 is rotatably connected between the inner walls of the housing 8. A rotating disk 16 is installed on the outside of the drive shaft 15. An unloading port 18 is opened on the bottom side of the housing 8, and the position of the unloading port 18 corresponds to the position of the second conveyor belt 10, and a baffle is also provided between them. A drive wheel 20 is installed on the outer end of the drive shaft 15. A first motor 9 is also provided on the base plate 1. A synchronous drive belt is connected between the output end of the first motor 9 and the drive wheel 20.

[0022] Working principle: When the equipment is working, the first conveyor belt 4 is controlled to work, and the material in the feeding hopper 3 will start to be conveyed. The material will be input into the screening component 7. At this time, the second motor 13 is controlled to rotate, and the eccentric disk 14 will start to rotate. During the rotation, the contact wheel 5 will be pushed up and down continuously. At this time, under the action of the first spring 19, the screening component 7 will continuously vibrate up and down. After the material falls onto the upper screen plate 6, it will be screened for the first time. The screened material will fall into the lower screen plate 22 for a second screening. The screened material will fall into the second conveyor belt 10 for conveying and feeding. Under the continuous vibration of the screening component 7, the screened material falls into the outer opening 17 through the discharge receiving plate 21. The rotation of the first motor 9 will drive the rotating disk 16 to rotate, thereby rotating and breaking up large pieces of material. The broken material will fall directly onto the second conveyor belt 10 through the discharge port 18 for feeding.
