Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electrolytic slag secondary utilization, in particular to a device capable of realizing electrolytic slag secondary utilization. BACKGROUND

[0002] The device for electrolytic slag secondary utilization is commonly referred to as a slag treatment device or an electrolytic slag recovery device, which is used to treat and recover the generated slag to realize resource reuse and environmental protection. Before the electrolytic slag secondary utilization, the slag needs to be pretreated by using the slag treatment device for crushing, screening and other steps, so as to better perform subsequent treatment and recovery.

[0003] In the process of crushing and screening the slag by the existing slag treatment device, the crushed slag directly falls onto the upper side of the screen plate for screening. However, since the volume of the slag to be put in is generally different in size, when the volume of the slag is large, the amount of the crushed slag is also relatively large. When too much slag falls onto the upper side of the screen plate, not only will the screen plate and screen mesh be excessively worn due to the high-speed impact and friction of the slag, which will shorten the service life of the equipment and increase the cost of equipment maintenance and replacement, but also the excessive slag will be accumulated on the upper side of the screen plate, which will cause the screen mesh to be blocked, affect the screening effect, make the fine particles unable to pass through the screen mesh, reduce the screening yield, and the slag accumulated on the upper side of the screen plate will be disturbed by mechanical vibration or airflow, causing dust to be scattered, which will cause dust pollution to the working environment, have a negative impact on the health of the operators, and also pollute the surrounding environment.

[0004] Secondly, when the slag is crushed by using the crushing roller, part of the slag may not be completely crushed and directly fall onto the lower screen plate, which not only makes the impact force on the screen plate during the screening process larger, causing the screen mesh on the screen plate to be damaged, but also the larger volume of the slag falling onto the upper side of the screen plate is more likely to block the screen holes on the screen plate, further affecting the screening effect of the screen plate.

[0018] (Three) beneficial effects

[0019] Compared with the prior art, the present application provides a device capable of realizing secondary utilization of electrolytic slag, which has the following beneficial effects:

[0020] 1. The quantitative feeding mechanism can control the amount of the crushed slag falling above the screen plate, thereby reducing the abrasion caused by the impact force of the slag on the screen plate due to the excessive amount of the slag, prolonging the service life of the screen plate, reducing the maintenance cost, avoiding the blockage of the screen plate caused by the excessive amount of the slag, reducing the cleaning and maintenance time of the screen plate, ensuring the particle size and uniformity of the slag after screening, facilitating the subsequent secondary utilization of the slag by the staff, and reducing the generation of waste and dust, thereby reducing the impact of the dust and waste on the environment and the health of the staff.

[0021] 2. Through the flexible rack and toothed plate and transmission gear, the molten slag inside the storage box can be periodically added to the screen plate. This not only helps control the screening rhythm of the molten slag, ensuring the stable operation of the screen plate and improving the screening efficiency, but also makes the molten slag evenly distributed on the screen plate, which is beneficial to the uniformity of particles and the stability of product quality during the screening process. In addition, it can reduce manual intervention and reduce the opportunity for operators to come into contact with molten slag, thereby reducing the problem of too much or too little molten slag being added due to operator error, avoiding the situation of too much residual molten slag on the screen plate, and reducing the risk of screen plate blockage.

[0022] 3. Through the slag discharge mechanism, during the reciprocating sieving motion of the screen plate, the pusher plate can be driven to slide horizontally back and forth on the surface of the screen plate, pushing out the slag that is not completely crushed and cannot be screened from the discharge port. This not only cleans up the incompletely crushed slag in time, preventing it from mixing into the screened slag and ensuring the uniformity and stability of the screened slag, but also prevents large volumes of slag from jumping back and forth on the surface of the screen plate, protecting the safety of the screen plate and thus extending its service life.

[0023] 4. Through the anti-clogging screening mechanism, during the reciprocating screening process of the screen plate, the tapping plate below the screen plate can be driven to tap the bottom of the screen plate in turn. This can not only effectively remove impurities and agglomerates in the screen holes, reduce screen hole clogging, and reduce the risk of screen plate damage, but also make the slag evenly distributed on the screen plate, improve the screening effect of the screen plate, and improve the particle distribution and quality of the slag.

[0041] In this embodiment, as shown in Figure 2 Quantitative feeding mechanism 6 includes storage tank 601, both sides of storage tank 601 are fixedly connected with mounting plate 602, mounting plate 602 away from the storage tank 601 side are fixedly connected to the inner wall of slag treatment box 1, storage tank 601 is located between the crushing roller 3 and sieve plate 8, by setting the storage tank 601, can avoid the slag directly drop to the sieve plate 8 above, so as to buffer the impact force of the slag falling.

[0042] In this embodiment, as shown in Figure 4 The inside of the storage tank 601 is rotatably connected with a rotating shaft 605, the outer surface of the rotating shaft 605 is fixedly connected with a stirring plate 606 at equal intervals, and the side of the rotating shaft 605 away from the storage tank 601 is rotatably connected with the slag treatment box 1. When the rotating shaft 605 rotates, it can drive the stirring plate 606 to rotate synchronously in the storage tank 601, and push the slag in the storage tank 601 out.

[0043] In this embodiment, as shown in Figure 4 And Figure 5 The end of the rotating shaft 605 penetrating the slag treatment box 1 is fixedly connected with a transmission gear 608, one side of the transmission gear 608 is meshingly connected with a flexible rack plate 607, the side of the flexible rack plate 607 away from the transmission gear 608 is fixedly connected with a belt 604, the inside of the belt 604 is symmetrically transmission connected with a transmission pulley 603, and the transmission pulley 603 is fixedly connected to the outer surfaces of the driving shaft 501 and the connecting shaft 4, respectively. When the driving shaft 501 rotates, it can drive the connecting shaft 4 to rotate synchronously through the transmission pulley 603 and the belt 604, and make the flexible rack plate 607 move synchronously around the two transmission pulleys 603, and intermittently contact the transmission gear 608.

[0044] In this embodiment, as shown in Figure 3As shown, the driving shaft 501 is fixedly connected with a poking rod 504 close to one end of the slag treatment box 1, the poking rod 504 is provided with a frame 505 away from the driving shaft 501, the frame 505 is fixedly connected to the side wall of the sieve plate 8, and the poking rod 504 is slidably connected to the frame 505 away from the driving shaft 501. During the rotation of the driving shaft 501, the one end of the poking rod 504 can reciprocate in the frame 505 to push the sieve plate 8 to reciprocate left and right.

[0045] In this embodiment, as shown in the figure, Figure 9 As shown, the slag treatment box 1 is provided with a beating plate 506 symmetrically below the sieve plate 8, the beating plate 506 is fixedly connected with a connecting column 507 on both sides, the connecting column 507 is fixedly connected with a lifting block 502 away from the beating plate 506, the lifting block 502 is vertically slidably connected to the inner wall of the slag treatment box 1, and the connecting column 507 is rotatably connected with an elastic expansion plate 503 on the outer surface, the elastic expansion plate 503 is rotatably connected to the side wall of the sieve plate 8 away from the connecting column 507. During the reciprocating movement of the sieve plate 8, the two beating plates 506 can be sequentially reciprocated to beat the sieve plate 8 below through the elastic expansion plate 503, the connecting column 507 and the lifting block 502.

[0046] In the prior art, when too much slag falls on the sieve plate 8, not only will it cause excessive wear of the sieve plate 8 and the screen, but also the high-speed impact and friction of the slag will damage the sieve plate 8 and the screen, shorten the service life of the equipment, and increase the cost of equipment maintenance and replacement. In addition, too much slag will accumulate on the sieve plate 8, which will cause the screen to be blocked, affect the screening effect, make fine particles unable to pass through the screen, reduce the screening yield, and the slag accumulated on the sieve plate 8 will be disturbed by mechanical vibration or airflow, causing dust to be scattered, which will cause dust pollution to the working environment, negatively affect the health of the operators, and also pollute the surrounding environment. Compared with the prior art, the amount of crushed slag falling on the sieve plate 8 can be controlled, which not only reduces the wear caused by the increased impact force of the slag on the sieve plate 8 due to the excessive amount of slag falling during the falling process, thereby prolonging the service life of the sieve plate 8 and reducing maintenance costs, but also avoids the situation that the sieve plate 8 is blocked due to too much slag, reduces the cleaning and maintenance time of the sieve plate 8, ensures the particle size and uniformity of the slag after screening, so as to facilitate the subsequent secondary utilization of the slag by the workers, and reduces the generation of waste and dust, thereby reducing the impact of dust and waste on the environment and the health of the workers;

[0047] Secondly, the flexible rack plate 607 and transmission gear 608 can periodically feed the molten slag inside the storage box 601 onto the screen plate 8. This not only helps control the slag screening rhythm and ensures the stable operation of the screen plate 8, but also improves the slag screening efficiency and makes the molten slag evenly distributed on the screen plate 8, which is beneficial to the uniformity of particles and the stability of product quality during the screening process. Furthermore, it can reduce manual intervention and reduce the opportunity for operators to come into contact with the molten slag, thereby reducing the problem of too much or too little molten slag being fed due to operator error, avoiding the situation of too much residual molten slag on the screen plate 8, and reducing the risk of screen plate 8 clogging.

[0048] Furthermore, during the reciprocating sieving motion of the drive sieve plate 8, the tapping plate 506 below the sieve plate 8 can be driven to tap the area below the sieve plate 8 in turn. This not only effectively removes impurities and agglomerates from the sieve holes, reduces sieve hole blockage, and lowers the risk of damage to the sieve plate 8, but also ensures that the molten slag is evenly distributed on the sieve plate 8, improving the sieving effect of the sieve plate 8 and improving the particle distribution and quality of the molten slag.

[0049] At other levels, this embodiment also provides a slag discharge mechanism 7 for discharging incompletely crushed slag from inside the slag processing tank 1, such as... Figure 6 - Figure 8 As shown, the slag discharge mechanism 7 includes a pusher plate 704, which is slidably connected to the upper end face of the screen plate 8. Inclined plates 701 are symmetrically arranged below the screen plate 8. The inclined plates 701 are all fixedly connected to the inner side wall of the slag treatment box 1. The slag treatment box 1 is provided with a discharge port 10 on the side near the inclined plate 701.

[0050] In this embodiment, as Figure 7 and Figure 8 As shown, a support column 705 is slidably connected through the pusher plate 704, and the support column 705 is fixedly connected to the screen plate 8. A bidirectional threaded rod 702 is threadedly connected through the side of the pusher plate 704 away from the support column 705. One end of the bidirectional threaded rod 702 is rotatably connected to the screen plate 8, and the bidirectional threaded rod 702 penetrates the side wall of the slag treatment box 1. A hollow column 703 is sleeved on the outer surface of the end of the bidirectional threaded rod 702 penetrating the slag treatment box 1. The hollow column 703 is fixedly connected to the side wall of the slag treatment box 1. An annular reciprocating groove 706 is opened on the inner wall of the hollow column 703. A connecting rod 707 is slidably connected inside the annular reciprocating groove 706. The end of the connecting rod 707 away from the annular reciprocating groove 706 is fixedly connected to the bidirectional threaded rod 702. During the process of the screen plate 8 driving the bidirectional threaded rod 702 to move back and forth, the bidirectional threaded rod 702 can push the connecting rod 707 to slide back and forth along the path of the annular reciprocating groove 706 opened on the inner wall of the hollow column 703. In this way, the bidirectional threaded rod 702 can rotate synchronously while moving horizontally, and through the threaded connection between the bidirectional threaded rod 702 and the screen plate 8, it drives the screen plate 8 to slide back and forth on the outer surface of the support column 705.

[0051] Compared with the prior art, in the process of reciprocating screening of the screen plate 8, the pushing plate 704 can be driven to slide horizontally on the surface of the screen plate 8, so that the molten slag that is not completely crushed and cannot be screened out of the discharge port 10, not only can clean the molten slag that is not completely crushed in time, avoid mixing with the screened molten slag, ensure the uniformity and stability of the screened molten slag, but also can avoid the situation that the molten slag of large volume reciprocates on the surface of the screen plate 8, so as to protect the safety of the screen plate 8, thereby prolonging the service life of the screen plate 8.

[0052] The working process and principle involved in the above embodiment are as follows:

[0053] When the staff needs to crush and screen the molten slag, first, the driving source is opened to drive the driving shaft 501 to rotate, the driving shaft 501 drives one of the crushing rollers 3 to rotate synchronously through the belt 604 connected between the two transmission pulleys 603, and then the other crushing roller 3 is driven to rotate synchronously through the transmission of the prior art between the two crushing rollers 3, so that the two crushing rollers 3 cooperate with each other to crush the molten slag. The crushed molten slag falls into the storage tank 601. In the process of movement of the belt 604 around the two transmission pulleys 603, the flexible rack plate 607 connected to the outer surface of the belt 604 moves synchronously, drives the flexible rack plate 607 and the transmission gear 608 to contact, and through the meshing connection of the flexible rack plate 607 and the transmission gear 608, drives the rotating shaft 605 connected to the transmission gear 608 to rotate on the molten slag treatment tank 1 and the storage tank 601, so as to drive the stirring plate 606 arranged inside the storage tank 601 to rotate synchronously with the rotating shaft 605 as the center, and the molten slag stored in the storage tank 601 is successively stirred out from the inside of the storage tank 601 and falls onto the screen plate 8 below, so as to control the amount of the crushed molten slag falling onto the screen plate 8 above. Not only can reduce the impact of the molten slag on the screen plate 8 due to the excessive amount of the molten slag falling, thereby prolonging the service life of the screen plate 8 and reducing the maintenance cost, but also can avoid the blockage of the screen plate 8 due to the excessive amount of the molten slag, thereby reducing the cleaning and maintenance time of the screen plate 8, ensuring the particle size and uniformity of the molten slag after screening, so as to facilitate the subsequent secondary use of the molten slag by the staff, and can reduce the generation of waste and dust, thereby reducing the influence of the dust and waste on the environment and the health of the staff;

[0054] When the flexible rack plate 607 and the transmission gear 608 are separated, the transmission gear 608 cannot drive the rotating shaft 605 and the stirring plate 606 to rotate. When the flexible rack plate 607 moves one circle along with the belt 604, the flexible rack plate 607 will be in contact with the transmission gear 608 again, driving the transmission gear 608 to rotate, so that the molten slag in the storage tank 601 can be discharged onto the screen plate 8 at regular time intervals. This can not only help to control the screening rhythm of the molten slag, ensure the stable operation of the screen plate 8, improve the screening efficiency of the molten slag, make the molten slag evenly distributed on the screen plate 8, and be beneficial to the uniformity of particles and the stability of product quality in the screening process, but also can reduce manual intervention and reduce the opportunity for the operator to contact the molten slag, thereby reducing the problem of too much or too little molten slag caused by the mistake of the operator, avoiding the situation that there is too much residual molten slag on the screen plate 8, and reducing the risk of clogging of the screen plate 8;

[0055] In the process of rotating the driving shaft 501, the driving shaft 501 drives the stirring rod 504 to slide reciprocally in the frame 505 away from one end of the driving shaft 501, and the stirring rod 504 is connected with the molten slag treatment tank 1 through the slide column 9. The stirring rod 504 drives the screen plate 8 to slide reciprocally in the molten slag treatment tank 1. In the process of reciprocally sliding the screen plate 8, the elastic expansion plate 503 connected with one side of the screen plate 8 is extruded, and the lifting block 502 is driven to slide downward on the inner wall of the molten slag treatment tank 1 through the connection column 507 connected with the other end of the elastic expansion plate 503, and the beating plate 506 connected between the connection columns 507 is lowered. At the same time, the elastic expansion plate 503 connected with the other side of the screen plate 8 is pulled. When the screen plate 8 slides reversely, the lowered beating plate 506 is pulled by the connection column 507 and the elastic expansion plate 503, and is raised again to beat the lower end surface of the screen plate 8. Thus, in the process of reciprocally driving the screen plate 8, the beating plate 506 below the screen plate 8 is driven to slide reciprocally in turn, which can not only effectively remove the impurities and agglomerates in the screen holes, reduce the clogging of the screen holes, and reduce the risk of damage to the screen plate 8, but also can make the molten slag evenly distributed on the screen plate 8, improve the screening effect of the screen plate 8, and improve the particle distribution and quality of the molten slag;

[0056] When the screen plate 8 reciprocates, the bidirectional threaded rod 702 connected with the screen plate 8 can be driven to move synchronously, so that one end of the bidirectional threaded rod 702 reciprocates horizontally in the hollow column 703, and the connecting rod 707 is driven to move synchronously in the process of movement of the bidirectional threaded rod 702, at this time, the connecting rod 707 slides along the annular reciprocating groove 706 on the inner wall of the hollow column 703, so that the bidirectional threaded rod 702 is rotated while the connecting rod 707 moves horizontally, and the push plate 704 is driven to move horizontally on the upper end surface of the screen plate 8 through the threaded connection between the bidirectional threaded rod 702 and the push plate 704, so that the molten slag that is not completely crushed and cannot be screened on the screen plate 8 is pushed to both sides and falls on the inclined plate 701, slides along the inclined surface of the inclined plate 701, and is discharged from the discharge port 10 in the side wall of the molten slag treatment box 1. Not only can the molten slag that is not completely crushed be cleaned in time to avoid mixing with the screened molten slag, but also the uniformity and stability of the screened molten slag can be ensured, and the safety of the screen plate 8 can be protected, thereby prolonging the service life of the screen plate 8.
