Obviously, the described embodiments are some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present application.

[0024] According to Figure 1 , 2 , 3, 4, a gradient heating chain sintering kiln is provided in the embodiments, which comprises a kiln main body 1, a front support 2 and a rear support 5, the front support 2 and the rear support 5 are fixedly arranged on the left and right sides of the kiln main body 1, and the left and right sides of the kiln main body 1 are provided with inlets and outlets 8;

[0025] The front support 2 and the rear support 5 are provided with frame grooves 3 at the upper ends, and the frame grooves 3 are paved with chain plate conveying belts 4, and the chain plate conveying belts 4 pass through the inlets and outlets 8;

[0026] The workpiece to be sintered is placed on the chain plate conveyor belt 4, the chain plate conveyor belt 4 runs along the frame groove 3, and the workpiece is conveyed into the furnace from the left side inlet and outlet of the furnace main body 1, and after the sintering is completed in the gradient heating area in the furnace, it is conveyed to the rear support 5 area from the right side inlet and outlet, realizing continuous sintering and conveying of the workpiece. Compared with the traditional intermittent conveying mode, the chain plate conveyor belt 4 can realize continuous feeding and discharging of the workpiece into the furnace, greatly improving the sintering production efficiency. The chain sintering furnace is a relatively common type of furnace, which will not be described in detail here.

[0027] The front support 2 is provided with a rotating shaft 10, the rotating shaft 10 is arranged on one side of the chain plate conveyor belt 4 and detachably connected with the front support 2, two spiral bristles 11 are sleeved outside the rotating shaft 10, the spiral bristles 11 are fixedly connected with the rotating shaft 10 and in contact with the chain plate conveyor belt 4, the spiral directions of the two spiral bristles 11 are opposite, and the outer side of the front support 2 is provided with a power assembly for controlling the rotation of the rotating shaft 10.

[0028] The power assembly drives the rotating shaft 10 to rotate, and the two spiral bristles 11 outside the rotating shaft 10 rotate synchronously. Since the bristles are in contact with the surface of the chain plate conveyor belt 4, the sintering residues, dust and other impurities adhered to the surface of the conveyor belt can be cleaned during rotation. The spiral directions of the two spiral bristles 11 are opposite, the left bristle pushes the impurities to the outside of the conveyor belt when rotating, and the right bristle simultaneously pushes the impurities to the other side when rotating, so that the impurities are separated from the two sides of the conveyor belt. The spiral bristle 11 rotating cleaning mode has no dead angle and higher residue discharge efficiency, and avoids continuous adhesion of residues.

[0029] It is worth noting that the left and right ends of the rotating shaft 10 are respectively provided with a connecting cylinder 12 and a connecting column 17, one end of the connecting cylinder 12 is rotatably connected with the inner side wall of the frame groove 3, the other end of the connecting cylinder 12 is detachably connected with the rotating shaft 10 through a first lock pin structure, one end of the connecting column 17 is rotatably connected with the inner side wall of the frame groove 3, and the other end of the connecting column 17 is detachably connected with the rotating shaft 10 through a second lock pin structure.

[0030] When assembling, the two ends of the rotating shaft 10 are respectively connected with the connecting cylinder 12 and the connecting column 17, and then the first and second lock pin structures are locked to make the rotating shaft 10, the connecting cylinder 12 and the connecting column 17 form a whole that rotates synchronously. When disassembling, the two lock pin structures are unlocked to separate the rotating shaft 10 from the connecting cylinder 12 and the connecting column 17. When the bristles are worn out or the rotating shaft fails, they can be quickly replaced, reducing maintenance costs.

[0031] More specifically, the inner side of the connecting cylinder 12 is provided with a prismatic pin 13, the prismatic pin 13 penetrates through the connecting cylinder 12 and is slidably connected with the connecting cylinder 12, and the side of the rotating shaft 10 facing the connecting cylinder 12 is provided with a polygonal slot 14, the prismatic pin 13 is plug-connected with the polygonal slot 14.

[0032] More specifically, the rotating shaft 10 is provided with a slot 18 on the side close to the connecting column 17, and the connecting column 17 is plug-connected with the slot 18.

[0033] The first locking pin structure comprises a first lug 15 fixedly arranged on the end of the rotating shaft 10 close to the prismatic pin 13, the first lug 15 is staggered with the prismatic pin 13, and a second fixing pin 16 is assembled on the first lug 15 and passes through the first lug 15 and is threadedly connected with the pin hole arranged on the outer side of the prismatic pin 13.

[0034] When the rotating shaft 10 is assembled with the connecting cylinder 12, the prismatic pin 13 is slid to insert one end thereof into the polygonal slot 14 of the rotating shaft 10, the polygonal structure can transmit torque, so as to ensure that the connecting cylinder 12 and the rotating shaft 10 rotate synchronously, then the second fixing pin 16 on the first lug 15 is tightened to be threadedly matched with the pin hole on the outer side of the prismatic pin 13, so as to lock the position of the prismatic pin 13 and prevent it from being separated from the slot during rotation. When disassembling, the second fixing pin 16 is unscrewed, the prismatic pin 13 is slid to be separated from the polygonal slot 14, and then the rotating shaft 10 and the connecting cylinder 12 can be separated.

[0035] The second locking pin structure comprises a second lug 19 fixedly arranged on the end of the rotating shaft 10 close to the connecting column 17, the second lug 19 is staggered with the slot 18, and a third fixing pin 20 is assembled on the second lug 19 and passes through the second lug 19 and is threadedly connected with the pin hole arranged on the outer side of the connecting column 17.

[0036] When the rotating shaft 10 is connected with the connecting column 17, the connecting column 17 is inserted into the slot of the rotating shaft 10 to realize preliminary positioning and torque transmission, then the third fixing pin 20 on the second lug 19 is tightened to be threadedly connected with the pin hole on the outer side of the connecting column 17, so as to firmly lock the rotating shaft 10 and the connecting column 17 and avoid relative sliding. When disassembling, the third fixing pin 20 is loosened, and then the connecting column 17 can be pulled out of the slot 18 to complete the separation.

[0037] Regarding the power assembly:

[0038] The power assembly comprises a motor 6 fixedly arranged on the outer side of the front support 2, and the output end of the motor 6 is fixedly connected with the end of the connecting column 17 away from the rotating shaft 10.

[0039] The motor 6 outputs torque after starting, and the torque is directly transmitted to the connecting column 17. Since the connecting column 17 is fixed with the rotating shaft 10 through the second locking pin structure, and the rotating shaft 10 is fixed with the connecting cylinder 12 through the first locking pin structure, the torque is sequentially transmitted to the rotating shaft 10 and the connecting cylinder 12, so as to drive the rotating shaft 10 and the spiral brush 11 on the outer side to stably rotate and provide power for cleaning work.

[0040] In the preferred scheme, a dust cover plate 7 is arranged above the rotating shaft 10, and first fixing pins 9 are arranged at the left and right ends of the dust cover plate 7, penetrating the dust cover plate 7 and being threadedly connected with pin holes arranged at the upper end of the front support 2.

[0041] The arrangement of the dust cover plate 7 can effectively block impurities from the outside from entering the rotating connection part of the rotating shaft 10, avoid the jamming or wear caused by impurities, and ensure the smooth operation of the clean structure. The detachable connection mode of the dust cover plate 7 facilitates the inspection and maintenance of the clean structure below the dust cover plate 7 by the staff.

[0042] The working principle of the present application is as follows:

[0043] The workpiece to be sintered is placed on the chain plate conveyor belt 4, the chain plate conveyor belt 4 runs along the frame groove, and the workpiece is conveyed into the furnace from the left side inlet and outlet of the kiln main body 1, and after the sintering is completed in the gradient heating area in the furnace, the workpiece is conveyed to the rear support 5 area from the right side inlet and outlet, realizing continuous sintering and conveying of the workpiece;

[0044] During the sintering process, the power assembly drives the rotating shaft 10 to rotate, and the two spiral bristles 11 on the outside are synchronously rotated. Since the bristles are in contact with the surface of the chain plate conveyor belt 4, the sintering residues, dust and other impurities attached to the surface of the conveyor belt can be cleaned during the rotation. The spiral directions of the two spiral bristles 11 are opposite, and the impurities are pushed to the outside of the conveyor belt when the left bristle rotates, and the impurities are simultaneously pushed to the other side when the right bristle rotates, so that the impurities are separated from the conveyor belt on both sides. The spiral bristle 11 rotates and cleans the area without dead angles, and the residue removal efficiency is higher, avoiding the continuous attachment of residues.
