The elastic member 392 can act on the adjusting rod 391 and the slag crushing shell 31, that is, the elastic member 392 is sleeved on the periphery of the adjusting rod 391 and acts on the end of the adjusting rod 391 facing the jaw 37 and the slag crushing shell 31, so that the adjusting rod 391 can elastically adjust the gap between the jaw 37 and the roller 36.
The elastic member 392 may also act on the adjustment rod 391 and the jaw 37, that is, both ends of the elastic member 392 are respectively connected to the jaw 37 and the end of the adjustment rod 391, so that the adjustment rod 391 elastically adjusts the gap between the jaw 37 and the roller 36.
According to different application scenes, the granularity of the slag to be crushed is different, the granularity of the crushed slag after crushing is also different, and the adjusting device 39 can change the gap between the jaw plate 37 and the roller wheel 36 according to different requirements so as to crush the slag into the crushed slag with different granularity, protect the gear teeth of the roller wheel 36 and prolong the service life of the crushed slag. In addition, due to the existence of the elastic piece 392, when the roller 36 breaks hard slag lumps, the elastic piece 392 can well buffer the impact force of the roller 36, and further protect the gear teeth of the roller 36.
The slag crushing device 300 also has a slag cleaning and blocking function, when the slag crushing device 300 is blocked by large slag through the reverse rotation mode of the slag crushing motor 32, the slag crushing motor 32 drives the roller wheel 36 to rotate reversely through the transmission mechanism 34, the large slag is cleaned, if the blocked slag cannot be cleaned successfully through one reverse rotation, the slag crushing motor 32 performs the second reverse rotation action, if the blocked slag cannot be cleaned successfully through the second reverse rotation, the slag crushing motor 32 performs the third reverse rotation action, and if the blocked slag cannot be cleaned successfully through the third reverse rotation, the slag crushing device 300 stops working, and an alarm signal is sent out to prompt a worker to overhaul.
The slag crushing device 300 is used for crushing the slag to obtain crushed slag with smaller granularity, so that the slag crushing device is convenient to transport, improves the conveying efficiency and is easy for subsequent separation of the slag and the waste iron; the automatic cleaning of the large block of blocked slag through the reversing function of the slag crushing device 300 saves manual work for entering the internal cleaning, not only saves the maintenance cost, but also avoids the risk of injury when cleaning personnel clean the blocked slag.
Referring to fig. 2 and 11, the separating device 400 includes a frame 41, a transfer motor 42, a transmission shaft 43, a magnetic separation roller 44, a transmission wheel 45 and a conveying belt 46. The frame 41 is a frame structure and is fixedly disposed below the slag crushing device 300. The transferring motor 42 is fixedly arranged on the frame 41 and provides driving force for transferring the crushed slag by the separating device 400.
The transmission shaft 43 is rotatably provided on the frame 41, and one end of the transmission shaft 43 is connected to the output end of the transfer motor 42, so that the transfer motor 42 drives the transmission shaft 43 to rotate.
The transmission shaft 43 is rotatably connected to the frame 41 through a bearing.
The magnetic separation roller 44 and the transmission wheel 45 are rotatably arranged on the frame 41, and the magnetic separation roller 44 and the transmission wheel 45 are arranged at intervals, so that the falling point of the crushed slag discharged from the slag discharge port 312 is positioned between the transmission wheel 45 and the magnetic separation roller 44.
The conveyor belt 46 connects the magnetic separation drum 44 and the transmission wheel 45 and can move around the magnetic separation drum 44 and the transmission wheel 45 to convey the crushed slag discharged from the slag discharge port 312.
The transmission shaft 43 is connected with any one of the magnetic separation roller 44 and the transmission wheel 45, so that the transfer motor 42 drives the transmission shaft 43 to rotate, the magnetic separation roller 44 and the transmission wheel 45 are driven to be linked, and the conveying belt 46 moves to transfer the crushed slag.
The transmission shaft 43 can be connected with the magnetic separation roller 44, and can also be connected with the transmission wheel 45, which can be determined according to the actual situation on site, as long as the transfer motor 42 can move the conveying belt 46 through the transmission shaft 43. The following description will be made by taking an example in which the magnetic separation drum 44 is fixedly connected to the transmission shaft 43 and the transmission wheel 45 is rotatably provided on the frame 41.
The magnetic separation roller 44 can be fixedly connected to the transmission shaft 43 through a key and a key groove, and can also be fixedly connected in other modes such as welding, as long as the transmission shaft 43 can drive the magnetic separation roller 44 to synchronously rotate.
The width of the conveyor belt 46 is greater than the width of the slag discharge port 312, and may be greater than or equal to 1m, so as to prevent the crushed slag from falling out of the conveyor belt 46.
When the crushed slag moves to the vicinity of the magnetic separation roller 44 along with the conveyor belt 46, the second type material 492 which can be magnetically attracted and such as iron sheet in the crushed slag can be adsorbed on the conveyor belt 46 due to the adsorption effect of the magnetic separation roller 44 on the magnetic material, the second type material 492 is conveyed to the second position 482 through the conveyor belt 46, and the first type material 491 which cannot be magnetically attracted and such as the crushed slag is separated from the second type material 492 when moving to the first position 481.
The first position 481 is a position where the magnetism of the magnetic separation roller 44 is strong, the second position 482 is a position where the magnetism between the magnetic separation roller 44 and the transmission wheel 45 is weak, and the second position 482 is on the lower surface of the conveyor belt 46.
When the slag is moved to the magnetic separation drum 44 via the conveyor belt 46, the first type material 491 which cannot be magnetically attracted falls freely at the first position 481 since the conveyor belt 46 is changed from horizontal movement to downward movement at this position. The second type of material 492 can be attracted by the magnetic separation roller 44, so that the second type of material 492 can be attracted to the conveyor belt 46 to move continuously.
As the second type of material 492 is attracted to the conveyor belt 46 and moves further and further away from the magnetic separation roller 44 as the conveyor belt 46 moves, the magnetic separation roller 44 becomes less attractive to the second type of material 492 until the second type of material 492 moves to a second location 482 where the magnetic attraction is insufficient to attract the second type of material 492 to the conveyor belt 46, causing the second type of material 492 to fall.
The recycling device 47 includes a first material box 471 and a second material box 472, and the first material box 471 and the second material box 472 are arranged below the magnetic separation roller 44 at intervals along the moving direction of the conveyer belt 46 to collect the first material 491 and the second material 492 respectively, so as to facilitate subsequent processing.
Specifically, first material tank 471 and second material tank 472 are located below first position 481 and second position 482, respectively, such that first material 491 and second material 492 are free to fall into first material tank 471 and second material tank 472 at first position 481 and second position 482, respectively.
When the first material tank 471 or the second material tank 472 is full of material, the empty material tank can be directly replaced to continue collecting, and the full material tank is transferred to the next processing technology.
The separating device 400 separates the first type material 491 and the second type material 492 in the slag, and the first type material 491 and the second type material 492 are respectively collected, so that the subsequent treatment is convenient.
In conclusion, the slag continuous processing equipment synchronously and continuously executes the respective independent slag collecting, crushing and separating processes, so that the working efficiency and the safety and stability coefficient are greatly improved, and the labor cost is greatly reduced.
In addition, other changes may be made by those skilled in the art within the spirit of the present application, and it is understood that such changes are encompassed within the scope of the present disclosure.
