Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of steel preparation and processing, and specifically to a high-quality steel preparation apparatus for precise removal of impurities. Background Technology

[0002] High-quality steel requires extremely high purity. Large particulate impurities in the raw materials (such as metal oxides and ore fragments) can directly cause defects such as cracks and inclusions inside the steel, seriously affecting its mechanical properties and service life. Therefore, the removal of raw material impurities is a core pre-process in the preparation of high-quality steel. As the steel industry develops towards high-end products, the shortcomings of traditional raw material screening equipment are becoming increasingly apparent: existing equipment has a single screening method for large particulate impurities, which is inefficient and makes it difficult to quickly and accurately separate large particulate impurities from the raw materials, thus restricting the quality and production efficiency of high-quality steel.

[0003] The drawbacks of traditional screening equipment are particularly prominent: most of them adopt a single vibrating screen screening mode, which makes it easy for large particles of impurities to clog the screen holes, causing the screening process to be interrupted and requiring frequent shutdowns for cleaning, further reducing processing efficiency; some equipment has poor screen aperture adjustment flexibility and cannot adapt to large particles of impurities of different sizes, resulting in incomplete separation. The remaining large particles of impurities will enter the subsequent smelting and rolling processes with the raw materials, increasing the defect rate of steel; in addition, traditional equipment lacks targeted grading screening design. The screening of large particles of impurities mixed with raw materials is not only time-consuming, but also causes raw material loss due to impurity collisions, increasing production costs.

[0004] Therefore, developing a high-quality steel preparation device that can accurately separate large particulate impurities and improve processing efficiency has become an urgent need to solve the pain points of traditional equipment and ensure the purity of high-quality steel. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a high-quality steel preparation device for precise removal of impurities, which solves the technical problem that the existing equipment has a single screening method for large particulate impurities, low efficiency, and difficulty in quickly and accurately separating large particulate impurities in raw materials.

[0006] According to one aspect, at least one embodiment of this disclosure provides a high-quality steel preparation apparatus for precise removal of impurities, characterized in that it comprises: The outer casing and the feeding hopper, wherein the feeding hopper is installed at one end of the top of the outer casing; A screening assembly, wherein the screening assembly is disposed inside the housing; A material separation and discharge assembly is disposed at one end of the bottom of the housing; The screening assembly includes a pair of side frames, which are movably fitted inside the outer shell on both sides. Several buffer springs are connected between the inner surface of the side frame and the outer surface of the outer shell. A screen plate is provided between the side frames, and a vibration motor is installed on the outer side of the side frame.

[0007] As a further technical solution, a mounting bracket is provided on one side of the side frame, one end of the mounting bracket is inclined downward, and a slot is opened on the side surface of the mounting bracket, and the sieve plate is slidably inserted between the slots.

[0008] As a further technical solution, a baffle plate is rotatably connected to the side end face of the mounting frame, the baffle plate is attached to the outer end face of the screen plate, and a conveyor belt is provided inside the outer shell, the conveyor belt being inclined at the same angle as the screen plate.

[0009] As a further technical solution, the surface of the conveyor belt is provided with several push plates, and a certain gap is left between the lower end face of the push plate and the surface of the screen plate. A pressure plate is fixedly connected inside the outer shell, and the pressure plate slides against the inner bottom surface of the conveyor belt.

[0010] As a further technical solution, an operation port is provided on the side surface of the outer shell, the operation port is located on the side of the highest point of the sieve plate, a sleeve is provided on the side surface of the outer shell, a door panel is inserted and connected in the sleeve, and the door panel covers the operation port.

[0011] According to another aspect, in at least one embodiment of the present invention, the separating discharge component includes a pair of bottom covers, each of which is disposed at one end of the bottom of the outer shell and is connected to the interior of the outer shell, and a pushing auger is installed inside the bottom cover.

[0012] As a further technical solution, a discharge pipe is provided on the side surface of the bottom cover, one end of the pusher auger extends into the discharge pipe, and a partition is provided on one end of the bottom surface of the outer shell. The partition is located at the interval between the bottom covers, and the upper end of the partition is located below the lowest point of the screen plate.

[0013] As a further technical solution, a large gap is left at the connection between the side frame and the outer shell.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: This disclosure addresses the problems of limited screening methods and low efficiency in traditional equipment by using a screening assembly. The side frame, in conjunction with buffer springs, provides a stable high-frequency vibration space for the screen plate. A vibration motor drives the screen plate to vibrate rapidly, accelerating the separation of raw materials from large particles of impurities, preventing impurities from clogging the screen holes, eliminating the need for frequent shutdowns for cleaning, and the buffer springs effectively absorb the vibration impact, reducing damage to the main body of the equipment and extending its service life.

[0015] The inclined structure of the mounting frame guides the raw material to slide naturally. Slots and baffles allow for quick assembly and disassembly of the screen plate, enabling flexible replacement of the screen plate according to the raw material particle size, improving equipment adaptability. The conveyor belt and screen plate are inclined at the same angle. The push plate moves in the opposite direction with the conveyor belt, pushing the raw material back to slow down the rolling speed and ensure sufficient time for screening, avoiding incomplete separation due to excessively fast material movement. The pressure plate ensures a stable distance between the push plate and the screen plate, further improving screening accuracy. The design of the operating port and door panel simplifies screen plate maintenance, eliminating the need for complex disassembly. Overall, it achieves efficient and precise impurity screening, significantly improving raw material processing efficiency. Attached Figure Description

[0024] like Figures 1-4 As shown, it illustrates a high-quality steel preparation apparatus for precise impurity removal according to an embodiment of the present disclosure, comprising: The outer casing 1 and the feeding hopper 2 are installed at one end of the top of the outer casing 1; Screening component 3, wherein the screening component 3 is disposed inside the outer casing 1; A material separation and discharge component 4 is disposed at one end of the bottom of the outer casing 1; The screening assembly 3 includes a pair of side frames 3-1, which are movably fitted into the two sides of the outer shell 1. Several buffer springs 3-2 are connected between the inner surface of each side frame 3-1 and the outer surface of the outer shell 1. A screen plate 3-3 is positioned between the side frames 3-1. A vibration motor 3-4 is mounted on the outer side of each side frame 3-1. A mounting bracket 3-5 is provided on one side of each side frame 3-1, with one end of the mounting bracket 3-5 tilting downwards. A slot 3-6 is formed on the side surface of the mounting bracket 3-5, and the screen plate 3-3 is slidably inserted into the slot 3-6. A baffle plate 3-7 is rotatably connected to the side end face of the mounting bracket 3-5, and the baffle plate 3-7 is attached to the outer end face of the screen plate 3-3. The outer casing 1 is equipped with a conveyor belt 3-8, which is inclined at the same angle as the sieve plate 3-3. Several push plates 3-9 are provided on the surface of the conveyor belt 3-8, and a certain gap is left between the lower end face of the push plate 3-9 and the surface of the sieve plate 3-3. A pressure plate 3-10 is fixedly connected inside the outer casing 1 and slides against the inner bottom surface of the conveyor belt 3-8. An operation port 3-11 is opened on the side surface of the outer casing 1 and is located on the highest point of the sieve plate 3-3. A sleeve 3-12 is provided on the side surface of the outer casing 1, and a door panel 3-13 is inserted and connected in the sleeve 3-12, covering the operation port 3-11.

[0025] In some examples, in order to achieve precise separation of steel raw materials and impurities and avoid the problem of incomplete screening caused by the excessively fast rolling of raw materials in traditional screening, a screening component 3 is designed. This component includes a pair of side frames 3-1 inside the outer shell 1, which are movably fitted by sliding sleeves. Several buffer springs 3-2 between the inner side of the side frame 3-1 and the outer side of the outer shell 1 are connected by hooks, which not only provide vibration space for the side frame 3-1, but also absorb the impact of vibration on the shell. The vibration motor 3-4 on the outer side of the side frame 3-1 is fixed by a motor base. When running, it drives the side frame 3-1 and the screen plate 3-3 to vibrate at high frequency, accelerating the separation of raw materials and impurities.

[0026] The mounting bracket 3-5 on one side of the side frame 3-1 is welded and fixed to the side frame 3-1. The tilt angle is adapted to the natural rolling direction of the raw material. The slot 3-6 on the side surface is precisely matched with the thickness of the screen plate 3-3. The screen plate 3-3 can be slidably inserted along the slot 3-6. The baffle plate 3-7 on the side end face of the mounting bracket 3-5 is rotatably connected by a pin and fits against the outer end face of the screen plate 3-3 to achieve limit fixation and prevent the screen plate 3-3 from shifting during vibration.

[0027] The conveyor belt 3-8 inside the outer casing 1 is installed via roller brackets, with the same inclination angle as the screen plate 3-3. Several push plates 3-9 on the surface are welded to the belt body, pushing the raw material in the opposite direction as the conveyor belt 3-8 rotates, slowing down the rolling speed and ensuring screening time. The pressure plate 3-10 is fixed to the inner bottom surface of the conveyor belt 3-8 by brackets, ensuring a stable distance between the push plates 3-9 and the screen plate 3-3 when the conveyor belt 3-8 is running. The operation port 3-11 on the side surface of the outer casing 1 is aligned with the highest point of the screen plate 3-3. The door plate 3-13 inside the sleeve 3-12 is inserted to cover the operation port 3-11. The screen plate 3-3 can be removed and replaced by opening the door plate 3-13, which is suitable for screening raw materials of different particle sizes. All components work together to improve the thoroughness and adaptability of screening.

[0028] like Figures 1-4 As shown in the figure, the present embodiment proposes that the distinguishing discharge component 4 includes a pair of bottom covers 4-1, each of which is disposed at one bottom end of the outer shell 1 and is connected to the interior of the outer shell 1. A pusher auger 4-2 is installed inside the bottom cover 4-1, and a discharge pipe 4-3 is provided on the side surface of the bottom cover 4-1. One end of the pusher auger 4-2 extends into the discharge pipe 4-3. A partition 4-4 is provided at one end of the bottom surface inside the outer shell 1. The partition 4-4 is located at the interval between the bottom covers 4-1, and the upper end of the partition 4-4 is located below the lowest point of the screen plate 3-3.

[0029] In some examples, in order to achieve separate collection of raw materials and impurities after screening and avoid the problem of impurity removal failure caused by mixing of materials in traditional discharge, a separation discharge component 4 is designed. This component includes a pair of bottom covers 4-1 at one end of the bottom of the outer shell 1, which are fixed by bolts. The top opening is connected to the inside of the outer shell 1, corresponding to the impurity drop area and the raw material drop area below the screen plate 3-3, respectively, to achieve classified collection. The push auger 4-2 inside the bottom cover 4-1 is horizontally rotatably connected by a bearing seat. One end is driven by an external drive motor through a coupling, and the other end extends into the discharge pipe 4-3 on the side surface of the bottom cover 4-1 to form a stable conveying link.

[0030] The discharge pipe 4-3 is rigidly connected to the bottom cover 4-1 via a flange, and can receive the collection device externally. When the auger 4-2 is running, it accurately transports the material in the bottom cover 4-1 to the pipe for discharge, avoiding accumulation and blockage. The partition plate 4-4 at one end of the bottom surface of the outer shell 1 is welded and fixed to the shell. It is located at the interval between the two bottom covers 4-1, and its upper end extends to the bottom of the screen plate 3-3, forming a physical separation barrier.

[0031] After screening, fine impurities fall through the mesh of screen plate 3-3 into one side of the bottom cover 4-1, while qualified raw materials roll along screen plate 3-3 to the other side of the bottom cover 4-1. The partition plate 4-4 prevents the two from mixing, ensuring accurate classification. The spiral blades of the pushing auger 4-2 have a small gap with the inner wall of the bottom cover 4-1, allowing for thorough conveying of residual materials and preventing cross-contamination. The double bottom covers 4-1 and the double augers operate independently, adapting to different discharge requirements for raw materials and impurities, ensuring high precision in impurity removal.

[0032] For example, such as Figure 1 As shown, there is a large gap between the side frame 3-1 and the outer shell 1.

[0033] In some examples, the side frame 3-1 is movably fitted inside the outer casing 1 on both sides via guide posts and sliding sleeves. A large gap is reserved at the connection between the side frame 3-1 and the outer casing 1, the size of which is adapted to the maximum vibration stroke of the vibrating motor 3-4 driving the side frame 3-1. This gap provides sufficient vibration space for the side frame 3-1, avoiding collision and friction between the side frame 3-1 and the inner wall of the outer casing 1 during vibration, thus preventing component wear or vibration attenuation. The buffer springs 3-2 between the inner side of the side frame 3-1 and the outer side of the outer casing 1 are evenly distributed circumferentially along the side frame 3-1, forming a stable vibration guiding structure with the gap, ensuring that the side frame 3-1 drives the screen plate 3-3 to vibrate at high frequency in a preset direction. Flexible dustproof covers are installed at the gaps to seal and prevent screening dust from entering and affecting the sliding fit, ensuring smooth movement of the side frame 3-1 and screening efficiency.

[0034] In actual use: Securely fix the outer casing 1 in the preset position, check that the connection between the side frame 3-1 and the movable assembly of the outer casing 1 is smooth and that the buffer spring 3-2 is firmly connected, slide the screen plate 3-3 into place through the slot 3-6 of the mounting bracket 3-5, rotate the blocking plate 3-7 to fit the outer end face of the screen plate 3-3 to achieve limiting, close the door panel 3-13 of the operating port 3-11 for sealing, start the vibration motor 3-4 on the outside of the side frame 3-1 to drive the side frame 3-1 and the screen plate 3-3 to vibrate at high frequency, the buffer spring 3-2 absorbs the vibration impact to protect the equipment, at the same time start the conveyor belt 3-8 inside the outer casing 1, the pressure plate 3-10 fits against the inner bottom surface of the conveyor belt 3-8 to ensure its smooth operation, the push plate 3-9 moves synchronously with the conveyor belt 3-8; put the steel raw material into the feeding hopper 2. The raw material slides naturally down the inclined screen plate 3-3. During the vibration, small qualified raw materials pass through the screen holes, while large impurities are trapped on the surface of the screen plate 3-3. The reverse push plate 3-9 pushes the raw material in the opposite direction to slow down the sliding speed and ensure thorough screening. After screening, the small raw materials and large impurities fall into the corresponding bottom covers 4-1 on both sides under the obstruction of the partition plate 4-4. The push auger 4-2 in the bottom cover 4-1 is started to transport the raw materials and impurities to the collection device through the corresponding discharge pipes 4-3. After the operation is completed, the vibration motor 3-4 and the conveyor belt 3-8 are turned off, the door plate 3-13 in the sleeve 3-12 is pulled out, the operation port 3-11 is opened, and the screen plate 3-3 can be pulled out for cleaning or replacement by rotating the baffle plate 3-7, thus completing one precise impurity removal process.

Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
