Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of steel slag processing, and in particular, to a vibrating feeder and a steel slag processing method. Background Art

[0002] In modern industrial production, vibrating feeders, as an important material conveying and screening equipment, are widely used in many fields such as mining, metallurgy, building materials, and chemicals. In the process of slag processing, the vibrating feeder is responsible for the key tasks of evenly and stably conveying materials to subsequent processing equipment and performing preliminary screening of materials. The quality of its working performance directly affects the efficiency of the entire production process and product quality.

[0003] The most prominent problem of traditional vibrating feeders is that the screen plate is very easy to wear during the screening process. When the existing vibrating feeder is actually working, the material continuously impacts the screen plate, and the screen plate is subjected to huge impact force. If it is in this working state for a long time, the screen plate will wear very quickly, and the screen hole deformation, screen plate rupture and other damages will frequently occur.

[0004] Frequent replacement of sieve plates not only increases the maintenance cost of the equipment, including the cost of purchasing new sieve plates and the production stagnation losses caused by stopping the machine to replace the sieve plates; on the other hand, frequent maintenance and replacement work reduces production efficiency, affects the continuity and stability of the entire production line, and cannot meet the needs of large-scale, high-efficiency production. In addition, the screening accuracy of the worn sieve plate decreases, which will lead to incomplete material screening, affect the quality of subsequent products, and reduce the effective utilization of resources.

[0026] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0027] like Figure 1 to Figure 9 As shown, it shows a vibrating feeder in one embodiment of the present disclosure, including a frame 1; a device body 2 is vibratingly arranged on the frame 1; a screening device 3 is arranged in the device body 2, and the screening device 3 divides the interior of the device body 2 into a coarse material chamber 201 and a fine material chamber 202, and the screening device 3 includes: a mounting frame 301 is arranged in the device body 2, and the upper and lower ends of the mounting frame 301 are respectively abutting part 1 3011 and abutting part 2 3012, the abutting part 1 3011 is located above the abutting part 2 3012, and a sliding space is formed between the abutting part 1 3011 and the abutting part 2 3012; a plurality of sieve plates 302 are arranged adjacent to each other in the sliding space in sequence, and are respectively arranged to slide vertically relative to the mounting frame 301; a plurality of first elastic members 304, and the two ends of the first elastic member 304 act on the abutting part 2 3012 and the sieve plate 302 respectively, so as to provide a force for the sieve plate 302 to move away from the abutting part 2 3012.

[0028] For example, Figure 1-Figure 5As shown, in order to solve the technical problem that the screen plate is easily worn by the continuous impact of materials when the vibrating feeder is screening in the prior art. The vibrating feeder is mainly composed of a frame 1, a device body 2 and a screening device 3. The frame 1 serves as the supporting base of the entire device, and the device body 2 is arranged on the frame 1 through an elastic component (such as a spring). A vibration motor is arranged on the device body 2, so that the device body 2 can generate stable vibration. The screening device 3 is arranged inside the device body 2, and the mounting frame 301 is fixed in the device body 2. A space for the screen plate 302 to slide is formed between the abutment part 1 3011 and the abutment part 2 3012 at the upper and lower ends. Several screen plates 302 are placed adjacent to each other in this sliding space, and can slide vertically along the mounting frame 301. A first elastic member 304 is installed between the abutment part 2 3012 and each screen plate 302. The first elastic member 304 has good elasticity and wear resistance, and can effectively buffer the impact force on the screen plate 302.

[0029] Specifically, after the equipment is started, the device body 2 starts to vibrate, and the material enters the coarse material chamber 201 from the feed port. Under the action of vibration, the material moves stably in the coarse material chamber 201, smaller material particles pass through the sieve holes and fall into the fine material chamber 202, and larger material particles remain on the sieve plate 302 and leave the coarse material chamber 201 from the outlet. During the screening process, when the sieve plate 302 slides downward, the first elastic member 304 is compressed to store elastic potential energy; when the sieve plate 302 rebounds upward, the first elastic member 304 releases elastic potential energy, providing an upward thrust to the sieve plate 302, thereby reducing the hard collision between the sieve plate 302 and the material.

[0030] The advantage is that the first elastic member 304 can effectively buffer the impact force of the material on the screen plate 302 , reduce the hard collision between the screen plate 302 and the material, thereby reducing the degree of wear of the screen plate 302 and extending the service life of the screen plate 302 .

[0031] In some examples, the screening device 3 further includes a plurality of positioning columns 303 , which are arranged on the second abutment portion 3012 , and the sieve plate 302 is vertically slidably arranged on the positioning columns 303 ; the first elastic member 304 is sleeved on the positioning columns 303 .

[0032] For example, Figure 4-Figure 5 As shown, a plurality of positioning posts 303 are evenly distributed and installed on the second abutment portion 3012. A through sliding hole is provided on the sieve plate 302 at the position corresponding to the positioning post 303, and the sieve plate 302 is sleeved on the positioning post 303 through the sliding hole to achieve vertical sliding. The first elastic member 304 is sleeved on the positioning post 303 and is located between the second abutment portion 3012 and the sieve plate 302, ensuring that the force of the elastic member can be accurately transmitted to the sieve plate 302.

[0033] The advantage is that the positioning column 303 provides a precise guide for the sliding of the screen plate 302, ensuring the stability and accuracy of the screen plate 302 during the vertical sliding process, and preventing the screen plate 302 from being worn due to shaking. At the same time, the buffering effect of the first elastic member 304 further reduces the impact force between the screen plate 302 and the material, protecting the screen plate 302 from excessive wear.

[0034] In some examples, a cleaning rod 4 is also included, which is located in the fine material chamber 202 and is arranged to cyclically move relative to the screening device 3 along the length direction of the screening device 3; the cleaning rod 4 has a plurality of air jets 401, and the air jets 401 face the screen plate 302; after the cleaning rod 4 moves relative to the screening device 3, the air jets 401 clean the plurality of screen plates 302 in turn.

[0035] For example, Figure 6 As shown, a cleaning rod 4 is added. The cleaning rod 4 is located in the fine material chamber 202 and can be cyclically moved along the length direction of the screening device 3. The cyclic movement of the cleaning rod 4 is moved by a chain and a sprocket installed on the inner wall of the device body. A mounting block is set on the chain, and the cleaning rod 4 is set on the mounting block. As the external motor drives the sprocket to rotate, the chain is driven to rotate, and the cleaning rod 4 is driven to move. The cyclic movement of the cleaning rod 4 can be achieved by the forward and reverse rotation of the external motor. The cleaning rod 4 is provided with a plurality of air jets 401 facing the screen plate 302.

[0036] Specifically, when the screen plate needs to be cleaned after the vibrating feeder has been working for a period of time, the moving mechanism of the cleaning rod 4 is started to move the cleaning rod 4 along the length direction of the screening device 3. At the same time, high-pressure gas is introduced into the cleaning rod 4 through an external gas source, and the high-pressure gas is ejected from the air jet 401 to clean the plurality of screen plates 302 in sequence.

[0037] The advantage is that the high-pressure gas ejected from the jet port 401 can directly act on the sieve holes on the sieve plate 302, blowing off the materials blocked in the sieve holes, effectively solving the problem of sieve hole blockage. The circular movement of the cleaning rod 4 can ensure that each sieve plate 302 is fully cleaned, thereby improving the cleaning efficiency and effect.

[0038] In some examples, the screening device 3 is vertically slidably disposed in the device body 2 , and the screening device 3 moves closer to or away from the air jet 401 after vertically sliding.

[0039] For example, Figure 2As shown, the screening device 3 is vertically slidably arranged in the device body 2 through the guide rail and the slider structure. In this way, the screening device 3 can move up and down in the device body 2, so as to approach or move away from the air jet 401 located in the fine material chamber 202. Specifically, when it is necessary to clean the sieve plate 302, the screening device 3 is vertically slid by the driving mechanism, approaching or moving away from the air jet 401. The air jet 401 sprays high-pressure gas to clean the sieve plate 302.

[0040] The advantage is that the screening device 3 can slide vertically toward or away from the air jet port 401, and the distance between the air jet port 401 and the sieve plate 302 can be adjusted according to actual conditions, so as to achieve the best air jet cleaning effect.

[0041] In some examples, it also includes a bellows 5, which is arranged in the fine material chamber 202 and below the screening device 3; the side wall of the bellows 5 is provided with a first air inlet 501 and a first air outlet 502, the first air inlet 501 is located outside the device body 2 and is connected with the high-pressure gas, and the first air outlet 502 is connected with the cleaning rod 4; the rotating shaft 6 is rotatably arranged in the bellows 5, and one end extends out of the bellows 5; there are a number of fan blades 7, and a number of fan blades 7 are arranged on the rotating shaft 6 and located in the bellows 5; after the high-pressure gas enters the bellows 5 through the first air inlet 501, it impacts a number of fan blades 7 in turn, so that the rotating shaft 6 rotates; the cam 8 is arranged at one end of the rotating shaft 6, outside the bellows 5, after the rotating shaft 6 rotates, the cam 8 contacts with the abutment part 2 3012, driving the screening device 3 to slide vertically.

[0042] For example, Figure 6 As shown, the high-pressure gas enters the wind box 5 from the first air inlet 501, impacts the fan blades 7, and rotates the shaft 6. The rotation of the shaft 6 drives the cam 8 to rotate, and the cam 8 contacts the second abutment portion 3012 during the rotation process, pushing the screening device 3 to slide vertically. At the same time, the high-pressure gas entering the wind box 5 flows from the first air outlet 502 to the cleaning rod 4, and is ejected from the air jet 401 to clean the sieve plate 302.

[0043] The advantage is that the energy of high-pressure gas is used to drive the rotating shaft 6 to rotate, thereby driving the screening device 3 to slide vertically, achieving effective use of energy, reducing the use of additional power sources, and reducing the energy consumption of the equipment. The rotation of the cam 8 can make the screening device 3 slide vertically periodically, which cooperates with the cleaning action of the air jet 401 to further improve the cleaning effect of the screen plate 302. The setting of the bellows 5 combines the flow of gas and power transmission, making the structure of the entire cleaning and screening device 3 more compact and saving equipment space.

[0044] In some examples, the screening device 3 also includes a locking rod 305, which is rotatably set on the abutment part 2 3012, and a number of tightening blocks 306 are set on the locking rod 305, and both ends of the tightening blocks 306 are tightening parts 3061; after the locking rod 305 is rotated, the two tightening parts 3061 respectively contact the sieve plate 302 and the abutment part 2 3012, so as to limit the relative position of the sieve plate 302 and the mounting frame 301.

[0045] For example, Figure 5 As shown, a rotation connection point is provided at the abutment part 3012, and the locking rod 305 is rotatably installed on the abutment part 3012 through the connection point. A plurality of tightening blocks 306 are installed at intervals on the locking rod 305, and the shapes of these tightening blocks 306 are specially designed, and the two ends farthest apart are both tightening parts 3061. The edge of the sieve plate 302 is provided with an abutment area adapted to the tightening part 3061. Under normal working conditions, the locking rod 305 is in a loosened position, and the tightening part 3061 does not contact the sieve plate 302, so that the sieve plate 302 can slide vertically freely in the mounting frame 301; when cleaning is required, the locking rod 305 is manually rotated to make the tightening block 306 rotate with the locking rod 305 until the tightening part 3061 tightly abuts against the edge and abutment part of the sieve plate 302, so as to The sieve plate 302 is fixed in the mounting frame 301, and a limit rod is also provided on the abutment portion 3012. The limit rod can limit the rotation range of the locking rod 305 by contacting the tightening portion 3061. At the same time, a telescopic rod is also provided on the abutment portion 3012. When the locking rod 305 is rotated into place, the telescopic rod is adjusted to make the telescopic rod contact with the tightening block 306 to limit the rotation of the locking rod 305 and avoid accidental touch when the locking rod 305 does not need to rotate.

[0046] Specifically, during normal operation, the sieve plate 302 freely slides vertically in the mounting frame 301 under the action of the vibration of the device body 2 to screen the material. When the sieve plate 302 needs to be cleaned, the feeding of the vibrating feeder is first stopped, and then the locking rod 305 is manually rotated to fix the sieve plate 302. Then, high-pressure gas is injected into the bellows 5 to rotate the cam 8, so that the entire screening device 3 repeatedly slides vertically close to the cleaning rod 4 with the air jet 401 to clean the sieve plate 302. After the cleaning is completed, the screening device 3 is reset, the locking rod 305 is rotated in the opposite direction, the sieve plate 302 is released, the free sliding state of the sieve plate 302 is restored, the feeding is restarted, and the screening work is continued.

[0047] The advantage is that the state of the sieve plate 302 can be accurately controlled: through the design of the locking rod 305 and the top tightening block 306, the relative position of the sieve plate 302 and the mounting frame 301 can be accurately controlled in both normal working and cleaning states to meet the needs of different working stages. When cleaning, the sieve plate 302 is fixed to allow the screening device 3 to slide as a whole, thereby ensuring the stability of the sieve plate 302 during the cleaning process, while maximizing the sliding range of the sieve plate 302, improving the cleaning efficiency, and avoiding energy loss and travel waste caused by the sliding of the sieve plate 302 alone.

[0048] In some examples, a limit block 9 is also included, which is arranged on the inner wall of the device body 2 and is located above the screening device 3; one end of the rotating handle 10 is arranged on the side of the cam 8 away from the bellows 5, and the other end is located outside the frame 1; after the rotating handle 10 is rotated, the cam 8 is driven to rotate, so that the screening device 3 slides vertically upward, so that the abutment part 3011 contacts the limit block 9, which is used to limit the relative position of the screening device 3 and the frame 1.

[0049] For example, Figure 1 and Fig. 9 As shown, a limit block 9 is installed on the inner wall of the frame 1, corresponding to the position above the screening device 3. The limit block 9 can be fixed to the frame 1 by bolts, and its position is precisely measured and adjusted to ensure that the vertical sliding position of the screening device 3 can be accurately limited. A rotating handle 10 is installed on the side of the cam 8 away from the bellows 5 by key connection or welding. The rotating handle 10 has a moderate length, one end is tightly connected to the cam 8, and the other end extends to the outside of the frame 1, which is convenient for operators to operate outside the equipment.

[0050] Specifically, when the vibrating feeder is ready for normal processing, the operator stands outside the frame 1, holds the rotating handle 10 with both hands and rotates it clockwise. The rotating handle 10 drives the cam 8 to rotate synchronously. The special profile of the cam 8 continuously pushes the abutment part 2 3012 at the bottom of the screening device 3 during the rotation process. Under the push of the cam 8, the screening device 3 overcomes its own gravity and friction and slides vertically upward. As the screening device 3 continues to rise, the abutment part 1 3011 at its top gradually approaches the limit block 9. When the abutment part 1 3011 is in close contact with the limit block 9, the vertical movement of the screening device 3 is restricted. At this time, the operator can limit the position of the rotating handle 10 by a simple fixing device (such as a latch, a lock, etc.), thereby stably fixing the screening device 3 in the device body 2 to ensure that the screening device 3 will not be displaced during the processing.

[0051] The advantage is that, through the cooperation of the limit block 9 and the rotating handle 10, the screening device 3 can be accurately fixed, thereby preventing the screening effect and the stability of the equipment operation from being affected by the displacement of the screening device 3.

[0052] In some examples, the screening device 3 also includes a sliding mounting plate 307, which is slidably set on the abutment portion 3012, and the positioning column 303 is set on the sliding mounting plate 307; the screen plate 302, the positioning column 303, the first elastic member 304 and the sliding mounting plate 307 together form a number of disassembly parts; after the sliding mounting plate 307 slides, the number of disassembly parts are separated from the mounting frame 301 in turn.

[0053] For example, Figure 5 As shown, two linear slide rails parallel to each other are installed on the abutment part 2 3012 at the bottom of the screening device 3, and the slide rails are firmly fixed on the abutment part 2 3012 by high-strength bolts. Slide blocks adapted to the slide rails are installed on both sides of the bottom of the sliding mounting plate 307 to ensure that the sliding mounting plate 307 can slide smoothly on the slide rails. The positioning column 303 is vertically installed on the sliding mounting plate 307, and then the first elastic member 304 and the sieve plate 302 are sequentially put on, so that the sieve plate 302, the positioning column 303, the first elastic member 304 and the sliding mounting plate 307 together constitute a complete disassembly and assembly component. A plurality of positioning pin holes are set on the side of the mounting frame 301, and positioning pins are set at corresponding positions on the sliding mounting plate 307. When the sliding mounting plate 307 slides into the mounting frame 301, the positioning pins can be accurately inserted into the positioning pin holes to ensure that the installation position of the disassembly and assembly component is accurate.

[0054] Specifically, when it is necessary to replace or maintain the sieve plate 302 and other components, first release the lock of the positioning pin, and then pull the sliding mounting plate 307 outward along the slide rail to gradually separate the entire disassembly assembly from the mounting frame 301. During the pulling process, the slider slides smoothly on the slide rail to ensure smooth movement of the disassembly assembly. The staff will take out the disassembly assembly as a whole, place it on a workbench that is easy to operate, and perform operations such as replacing the sieve plate 302, checking the first elastic member 304, or repairing the positioning column 303. After the replacement is completed, align the disassembly assembly with the slide rail and the positioning pin hole, push the sliding mounting plate 307, and accurately insert the positioning pin into the positioning pin hole to complete the installation. After the installation is completed, check the sliding condition of the sieve plate 302 and the elasticity of the first elastic member 304 to ensure that the equipment can operate normally.

[0055] The advantage is that it can be quickly maintained and replaced: the screen plate 302 and other components are combined into an integral disassembly assembly, which greatly shortens the time for equipment maintenance and replacement of components, reduces equipment downtime, and improves production efficiency.

[0056] like Fig.10As shown, it shows a steel slag processing method in another embodiment of the present invention, which is used for the sorting and transportation of converter steel slag, using a vibrating feeder, including a first circuit and a second circuit; the first circuit includes a tipping screening device 11, a storage bin 12, a vibrating feeder 13, a magnetic separator 14, a vibrating feeder 15 and a storage bin 16 connected in sequence to the material source; the second circuit includes a buffer bin 17 and a rod mill 18 connected in sequence to the coarse material outlet of the vibrating feeder 13; the discharge port of the rod mill 18 leads to the magnetic separator 14.

[0057] For example, Fig.10 As shown, a complete slag processing system is constructed at the production site of converter slag sorting and transportation. A first line is set up to connect the material source (such as the converter slag discharge port) to the tilting screening device 11 through a conveying pipeline or a belt conveyor. The tilting screening device 11 performs preliminary screening on the slag, removes large impurities and unqualified materials, and then transports the screened slag to the storage bin 12 through a discharge pipe. The bottom discharge port of the storage bin 12 is connected to a vibrating feeder 13, and the vibrating feeder 13 evenly transports the slag to a magnetic separator 14. The magnetic separator 14 separates the magnetic material and non-magnetic material in the slag through the magnetic field. The separated magnetic material and non-magnetic material are respectively connected to the vibrating feeder 2 15 through the discharge pipe, and the vibrating feeder 2 15 then transports the material to the storage bin 2 16 for storage. At the same time, a second line is set up, the coarse material outlet of the vibrating feeder 13 is connected to the buffer bin 17 through a pipeline, the bottom of the buffer bin 17 is connected to the rod mill 18, and the discharge port of the rod mill 18 is connected to the magnetic separator 14 through a pipeline.

[0058] Specifically, the steel slag enters the tilting screening device 11 from the material source. In the tilting screening device 11, large impurities and unqualified materials are separated through mechanical flipping and screening mechanisms, and the steel slag after preliminary screening falls into the storage bin 12. The steel slag in the storage bin 12 is evenly entered into the magnetic separator 14 under the vibration of the vibrating feeder 13. In the magnetic separator 14, the magnetic material and non-magnetic material of the steel slag move in different directions under the action of the magnetic field to achieve separation. The separated magnetic and non-magnetic materials enter the vibrating feeder 15, and the vibrating feeder 15 transports the materials to the storage bin 16 for storage. The coarse material of the vibrating feeder 13 enters the buffer bin 17, and after short-term storage and buffering in the buffer bin 17, it enters the rod mill 18 for grinding. The rod mill 18 grinds the coarse slag into smaller particles through the impact and grinding action of the grinding medium. The ground material enters the magnetic separator 14 through a pipeline for secondary magnetic separation, thereby further improving the separation accuracy of the slag.

[0059] The benefit is that through multi-link screening and processing, the different components in the steel slag are gradually separated, the sorting accuracy and efficiency of the steel slag are improved, and the steel slag is more fully utilized. Through reasonable connection between the equipment and the function of the vibrating feeder, the smooth transportation of materials is achieved, the blockage and accumulation of materials are reduced, and the continuity of the production process is guaranteed. The efficient sorting and transportation process improves the utilization rate of steel slag, reduces resource waste, reduces equipment failures and maintenance costs, and reduces overall production costs.

[0060] In some examples, a third circuit, a fourth circuit and a fifth circuit are also included; the third circuit is located between the discharge port of the rod mill 18 and the magnetic separator 14; the third circuit includes a vibrating feeder 3 19 and a vibrating feeder 4 20 which are sequentially connected to the discharge port of the rod mill 18, and the fine material outlet of the vibrating feeder 4 20 is connected to the magnetic separator 14; the fourth circuit includes a magnetic separator 21 which is sequentially connected to the coarse material outlet of the vibrating feeder 3 19; the non-magnetic discharge port of the magnetic separator 21 is connected to the vibrating feeder 2 15; the fifth circuit includes a buffer bin 22 and a rod mill 23 which are sequentially connected to the coarse material outlet of the vibrating feeder 4 20, and the discharge port of the rod mill 23 leads to the magnetic separator 14.

[0061] For example, Fig.10 As shown, the slag processing system is further improved. A third line is set between the discharge port of the rod mill 18 and the magnetic separator 14, and the vibrating feeder 3 19 and the vibrating feeder 4 20 are connected in sequence. The feed port of the vibrating feeder 3 19 is connected to the discharge port of the rod mill 18 through a pipeline, and the discharge port of the vibrating feeder 3 19 is connected to the feed port of the vibrating feeder 4 20 through a pipeline, and the fine material outlet of the vibrating feeder 4 20 is connected to the magnetic separator 14 through a pipeline. A fourth line is set, and the coarse material outlet of the vibrating feeder 3 19 is connected to the magnetic separator 2 21 through a pipeline, and the non-magnetic discharge port of the magnetic separator 2 21 is connected to the vibrating feeder 2 15 through a pipeline. A fifth line is set, and the coarse material outlet of the vibrating feeder 4 20 is connected to the buffer bin 2 22 through a pipeline, and the bottom of the buffer bin 22 is connected to the rod mill 2 23, and the discharge port of the rod mill 23 is connected to the magnetic separator 14 through a pipeline.

[0062] Specifically, the material ground by the rod mill 18 enters the vibrating feeder 3 19, and the vibrating feeder 3 19 preliminarily divides the material into fine material and coarse material according to the particle size and other characteristics of the material. The fine material enters the vibrating feeder 4 20, and the vibrating feeder 4 20 further screens and conveys the fine material, and conveys the fine material that meets the requirements to the magnetic separator 14 for magnetic separation. The coarse material of the vibrating feeder 3 19 enters the magnetic separator 2 21, and the magnetic separator 2 21 magnetically separates the coarse material to separate the magnetic material from the non-magnetic material. The non-magnetic material enters the vibrating feeder 2 15 and is conveyed to the storage bin 2 16 together with other fine materials. The coarse material of the vibrating feeder 4 20 enters the buffer bin 2 22, and after being buffered and stored in the buffer bin 2 22, it enters the rod mill 2 23 for grinding again. The rod mill 2 23 further grinds and refines the coarse material, and the ground material enters the magnetic separator 1 14 through a pipeline for processing, thereby improving the sorting quality and recovery rate of the steel slag.

[0063] The advantage is that by adding multiple lines and equipment, the steel slag can be classified and processed more finely, the sorting quality and recovery rate of the steel slag can be further improved, and the useful components in the steel slag can be more fully recycled. Targeted treatment of steel slag with different particle sizes and magnetic properties avoids the waste of resources, improves the comprehensive utilization value of steel slag, and conforms to the production concept of energy conservation and environmental protection. The multi-line design enables the system to be flexibly adjusted according to the different characteristics and production needs of steel slag, adapt to different production conditions, improve the stability and reliability of the production system, and reduce the impact of changes in steel slag characteristics on production.
