Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-5 In this embodiment of the utility model, a box-type sintering furnace includes a base 1, a support leg 2 fixedly connected to the bottom of the base 1, a heat insulation platform 3 fixedly connected to the base 1, a sintering furnace 4 fixedly connected to the heat insulation platform 3, a tail plate 5 at the tail end of the sintering furnace 4, a flue gas outlet 6 fixedly connected to the tail plate 5, a head plate 19 at the head of the sintering furnace 4, a lifting frame 23 fixedly connected to the base 1 at the head of the sintering furnace 4, a plurality of rollers 24 rotatably connected inside the lifting frame 23, a telescopic support rod 25 above the rollers 24, a limit block 26 fixedly connected to the bottom of the telescopic support rod 25, the limit block 26 and the rollers 24 cooperate with each other, a grab hook 27 rotatably connected to the side of the telescopic support rod 25 near the sintering furnace 4, and a spring 28 connected between the grab hook 27 and the telescopic support rod 25;

[0024] The sintering furnace 4 is provided with multiple sets of gas outlet pipes 12, and multiple sets of equally spaced nozzles 13 are provided in the gas outlet pipes 12. A connecting pipe 11 is fixedly connected in the gas outlet pipe 12, a gas supply pipe 15 is fixedly connected to the connecting pipe 11, an inlet pipe 16 is fixedly connected to the gas supply pipe 15, a mixing valve 17 is connected between the inlet pipe 16 and the gas supply pipe 15, and a check valve 14 is provided in the connecting pipe 11.

[0025] A rotating opening and closing assembly is installed between the head plate 19 and the sintering furnace 4; a telescopic drive assembly is installed between the telescopic support rod 25 and the base 1.

[0026] This invention first feeds the material into the sintering furnace 4, and then controls the head plate 19 and tail plate 5 to close by rotating the opening and closing assembly, thereby sealing the sintering furnace 4 through the head plate 19 and tail plate 5. Then, fuel and oxidant are injected into the mixing valve 17 through the air inlet pipe 16, thereby mixing the fuel and oxidant through the mixing valve 17. The mixed fuel is then injected into multiple sets of air outlet pipes 12 simultaneously through the air supply pipe 15 and connecting pipe 11, and then sprayed into the sintering furnace 4 through the nozzle 13. At this time, the material in the sintering furnace 4 can be heated and sintered by the combustion of fuel. During the sintering process, the heat is isolated by the head plate 19 and tail plate 5, and the exhaust gas generated by combustion is discharged through the flue gas outlet 6.

[0027] After sintering is completed, the head plate 19 is opened by rotating the opening and closing assembly. At this time, the telescopic drive assembly drives the telescopic support rod 25 to extend into the sintering furnace 4. During the extension process, the grab hook 27 is kept pressed down by the material rack. Then, when the grab hook 27 passes the material rack, the grab hook 27 is elastically raised by the elastic push of the spring 28. Then, the telescopic drive assembly drives the telescopic support rod 25 to be pulled out of the sintering furnace 4. At this time, the telescopic support rod 25 pulls the material out of the sintering furnace 4 through the grab hook 27.

[0028] In one instance of this embodiment, please refer to Figures 1-5 The rotating opening and closing assembly includes a fixed frame 18 fixedly connected to the sintering furnace 4, the top of the head plate 19 is rotatably connected to the fixed frame 18, a second hydraulic telescopic mechanism 21 is fixedly connected to the fixed frame 18, a rotating connector 22 is fixedly connected to the output shaft of the second hydraulic telescopic mechanism 21, one end of a rotating connecting rod 20 is rotatably connected inside the rotating connector 22, and the other end of the rotating connecting rod 20 is rotatably connected to the head plate 19;

[0029] The rotating opening and closing assembly first achieves the rotational installation and fixation of the head plate 19 through the rotational connection between the fixed frame 18 and the head plate 19. Then, when it is necessary to control the opening and closing of the head plate 19, the rotating connector 22 is driven to rise and fall by the second hydraulic telescopic machine 21. The rotating connector 22 drives the rotating connecting rod 20 to drive the head plate 19 to rotate and rise and fall around the rotational connection between the fixed frame 18 and the head plate 19 as the center, thereby controlling the rotational opening and closing of the head plate 19.

[0030] A fixed rod 7 is fixedly connected to the base 1, a sliding cylinder 8 is slidably connected to the fixed rod 7, a connecting frame 9 is fixedly connected to the sliding cylinder 8, the connecting frame 9 is fixedly connected to the tail plate 5, a first hydraulic telescopic machine 10 is fixedly connected to the base 1, and the output shaft of the first hydraulic telescopic machine 10 is fixedly connected to the connecting frame 9.

[0031] The rotating opening and closing assembly first achieves a sliding connection between the tail plate 5 and the fixed rod 7 and the sliding cylinder 8. Then, the first hydraulic telescopic machine 10 drives the connecting frame 9 to slide and extend horizontally. The connecting frame 9 drives the tail plate 5 to slide and extend at the tail of the sintering furnace 4, thereby achieving control over the opening and closing of the tail of the sintering furnace 4.

[0032] In one instance of this embodiment, please refer to Figures 1-5 The telescopic drive assembly includes a third hydraulic telescopic mechanism 29 fixedly connected to the bottom of the base 1. A drive frame 30 is fixedly connected to the output shaft of the third hydraulic telescopic mechanism 29, and the drive frame 30 is fixedly connected to the telescopic support rod 25.

[0033] The telescopic drive assembly drives the drive frame 30 to extend and retract via the third hydraulic telescopic machine 29, and the drive frame 30 drives the telescopic support rod 25 to slide and extend.
