Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a calcining furnace for preparing a carburizer, comprising a furnace body 1, a heating device for heating the furnace body 1 is arranged outside the furnace body 1, and the technology is a prior art and can be implemented by technicians in this field, so it will not be described in detail in this case.

The top of the bracket 2 is fixedly connected with a motor 35, and the output shaft of the motor 35 is fixedly connected with the rotating shaft of the gear 2 34. The rotating shaft of the gear 2 34 is at the center position of the gear 2 34. The outer wall of the rotating rod 32 passes through and is rotatably connected with the inner wall of the furnace body 1.

[0034] Reference Figure 2 . Figure 4 and Figure 5The fixing rod 31 passes through the inner wall of the furnace body 1, and the outer wall of the rotating rod 32 is fixedly connected with a mounting frame 36. The mounting frame 36 is in a frame shape, and the inner side of the mounting frame 36 matches the outer wall shape of the rotating rod 32, and the outer side of the mounting frame 36 matches the inner wall of the furnace body 1. The number of mounting frames 36 is set to be several, and several mounting frames 36 are in different vertical positions. The outer wall of the mounting frame 36 is fixedly connected with a scraper 37. The shape of the scraper 37 is arc-shaped, and the end of the scraper 37 away from the mounting frame 36 is set to a tip. The setting of the tip ensures that the scraper 37 can better scrape the raw materials adhering to the inner wall of the furnace body 1. The position setting of the mounting frame 36 ensures that the mounting frame 36 and the scraper 37 can scrape off the raw materials adhered to the inner wall of the furnace body 1 at different heights. The inner wall of the mounting frame 36 is penetrated by and rotatably connected with a rotating rod 38. The rotating rod 38 is located in the middle of the inner wall of the mounting frame 36. The outer wall of the rotating rod 38 is fixedly connected with a stirring blade 39. The outer wall of the rotating rod 38 is fixedly connected with a bevel gear three 310. The outer wall of the fixed rod 31 is fixedly connected with a bevel gear four 311. The bevel gear three 310 is meshed with the bevel gear four 311. The meshing relationship is set to ensure that the bevel gear three 310 can rotate under the control of the teeth of the bevel gear four 311.

[0035] Reference Figure 2 , Figure 4 and Figure 6 The interior of the furnace body 1 and the exterior of the rotating rod 32 are jointly provided with an anti-precipitation component 4, and the anti-precipitation component 4 includes a movable plate 41, the outer wall of the movable plate 41 is slidably connected to the inner wall of the furnace body 1, the sliding direction of the movable plate 41 is up and down sliding, and the bottom end of the movable plate 41 is fixedly connected with an extrusion block 42, the top view shape of the extrusion block 42 is a semi-circular shape, and the side view shape of the extrusion block 42 is a right-angled trapezoid, the outer wall of the rotating rod 32 at the lower end of the extrusion block 42 is fixedly connected with a rotating block 43, and the shape of the combination of the rotating block 43 and the extrusion block 42 when they are in the same plane is a semi-circular shape, and the outer wall of the rotating rod 32 at the upper end of the movable plate 41 is slidably connected with an anti-sticking rod 44, the length of the anti-sticking rod 44 is consistent with the diameter of the movable plate 41, and the bottom end of the anti-sticking rod 44 is rotatably connected to the top of the movable plate 41.

[0036] Working principle: During use, when the raw material is calcined inside the furnace body 1, the motor 35 drives the gear 2 34 to rotate clockwise, so that the gear 2 34 drives the gear 1 33 to rotate counterclockwise, so that the gear 1 33 drives the rotating rod 32 to rotate counterclockwise, and the rotating rod 32 drives the mounting frame 36 to rotate counterclockwise, so that the scraper 37, driven by the mounting frame 36, enables its tip to scrape off the raw material adhering to the inner wall of the furnace body 1.

[0037] At the same time, during the rotation of the mounting frame 36, since the bevel gear three 310 contacts the teeth of the bevel gear four 311 during the rotation, the bevel gear three 310 cannot only rotate with the mounting frame 36, but also rotates on its own, and drives the rotating rod 38 to rotate, so that the rotating rod 38 drives the stirring blade 39 to rotate, so that the stirring blade 39 drives the raw material to generate a force to move in the up and down directions, thereby preventing the raw material from moving downward due to the action of gravity, resulting in different heating effects of the raw materials in the upper and lower areas.

[0038] At the same time, during the rotation of the rotating rod 32, the rotating rod 32 drives the rotating block 43 to rotate. During the rotation of the rotating block 43, when the inclined surface of the rotating block 43 rotates in the direction of the movement of the inclined surface of the extruding block 42, the rotating block 43 drives the extruding block 42 to move upward, thereby causing the movable plate 41 to move upward, and drives the raw material on the movable plate 41 to move upward. When the rotating block 43 moves to a point where it is no longer in contact with the extruding block 42, the extruding block 42 and the movable plate 41 move downward under the action of gravity. Since the mass of the raw material is lighter than the weight of the movable plate 41, and the mounting frame 36 and the stirring blade 39 can drive the gas flow above the movable plate 41 when they rotate, the raw material is easier to enter the stirring area of ​​the stirring blade 39 and the mounting frame 36 under the action of the airflow driven by the stirring blade 39 and the mounting frame 36.

[0039] At the same time, the anti-sticking rod 44 is driven to rotate during the rotation of the rotating rod 32, so that the anti-sticking rod 44 can separate the raw materials adhering to the moving plate 41 from the moving plate 41, thereby preventing the raw materials from adhering to the upper surface of the moving plate 41 and affecting the calcination effect.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
