[0027] See also Figure 1-Figure 6The present invention provides a technical solution: an energy-saving ferrite sintering kiln, comprising a support plate 1, a furnace body 2 is arranged above the support plate 1, and the furnace body 2 is fixedly connected to the support plate 1; a plurality of ferrite trays 3 are arranged on the support plate 1; sealing doors 4 are arranged at the inlet and outlet positions on both the front and rear sides of the furnace body 2; a feeding mechanism is arranged on the support plate 1, and the feeding mechanism is used to push the ferrite tray 3 filled with ferrite into the furnace body 2; an arranging mechanism is arranged in the furnace body 2, and the arranging mechanism is used to arrange the ferrite trays 3 pushed into the furnace body 2 by the feeding mechanism at equal intervals; a material withdrawal mechanism is arranged in the furnace body 2, and the material withdrawal mechanism is used to push the ferrite tray 3 at the rearmost position in the furnace body 2 out of the furnace body 2;

[0028] During operation, a proper amount of ferrite is stacked in the ferrite tray 3, and then the ferrite tray 3 is placed in front of the furnace body 2 on the support plate 1. At this time, the sealing door 4 in front of the furnace body 2 is opened, and then the feeding mechanism is started. The feeding mechanism can push the ferrite tray 3 into the furnace body 2, and then the sealing door 4 is closed, which can effectively prevent the heat loss in the furnace body 2; when the feeding mechanism pushes the ferrite tray 3 into the furnace body 2, all the ferrite trays 3 in the furnace body 2 can be arranged at equal intervals under the action of the arrangement mechanism in the furnace body 2; when the ferrite tray 3 in the furnace body 2 is full, when the feeding mechanism pushes a new ferrite tray 3 into the furnace body 2 again, the ferrite tray 3 located at the rear side of the furnace body 2 that has completed sintering will be pushed out by the unloading mechanism. When the ferrite tray 3 is pushed out, the sealing doors 4 on the front and rear sides of the furnace body 2 are immediately closed, which can preserve the heat in the furnace body 2 to the greatest extent and achieve the effect of saving energy.

[0029] As a further solution of the present invention, the feeding mechanism comprises a first cylinder 5, the first cylinder 5 is fixedly connected to the support plate 1 and a push plate 6 is fixedly connected to the telescopic end of the first cylinder 5;

[0030] During operation, when a new ferrite tray 3 needs to be pushed into the furnace body 2, the sealed door 4 on the front side of the furnace body 2 is opened, and the first cylinder 5 is started at the same time. The first cylinder 5 will drive the push plate 6 to move forward, and the push plate 6 will push the ferrite tray 3 on the support plate 1 directly into the furnace body 2.

[0031] As a further solution of the present invention, the arrangement mechanism includes a first connecting frame 7, four baffles 8 are provided at the bottom of the first connecting frame 7, the distances between the four baffles 8 are equal, and the distance between two adjacent baffles 8 is equal to the width of the ferrite tray 3, the first three baffles 8 are fixedly connected to the first connecting frame 7, and the rear baffle 8 is rotatably connected to the first connecting frame 7; a reciprocating mechanism is provided on the first connecting frame 7, and the reciprocating mechanism is used to drive the four baffles 8 to move forward a distance of the width of the ferrite tray 3 without pushing the ferrite tray 3 backward;

[0032] During operation, when the ferrite tray 3 is pushed into the furnace body 2 by the push plate 6, the ferrite tray 3 will push the frontmost baffle 8 to move backward, and the frontmost baffle 8 will drive the other three baffles 8 to move backward at the same time through the first connecting frame 7; when the ferrite tray 3 is completely pushed into the furnace body 2, the push plate 6 is reset and the sealing door 4 of the furnace body 2 is closed. When the reciprocating mechanism drives the first connecting frame 7 to move upward, the first connecting frame 7 drives the four baffles 8 to move upward to the position above the ferrite tray 3. At this time, the reciprocating mechanism drives the first connecting frame 7 to move forward. After the first connecting frame 7 drives the four baffles 8 to move forward a distance of the width of the ferrite tray 3, the reciprocating mechanism will drive the first connecting frame 7 and the four baffles 8 to move downward. At this time, the frontmost baffle 8 is again in the frontmost position in the furnace body 2.

[0033] As a further solution of the present invention, the reciprocating mechanism includes a sliding frame 9, the sliding frame 9 is slidably connected to the furnace body 2, and the first connecting frame 7 is slidably connected to the sliding frame 9; the sliding frame 9 is rotatably connected to a first gear 10, the upper edge position of the first gear 10 is rotatably connected to a connecting rod 11, and the bottom end of the connecting rod 11 is rotatably connected to the first connecting frame 7; the sliding frame 9 is provided with a moving mechanism, and the moving mechanism is used to drive the sliding frame 9 to move forward when the first connecting frame 7 moves upward to the uppermost position;

[0035] The teeth of the first gear 10 are distributed in the lower part; the height distance from the connection point between the connecting rod 11 and the first gear 10 to the center of the first gear 10 is greater than the height of the ferrite tray 3;

[0036] The distribution length of the teeth on the rack 12 that are equal to the number of teeth on the first gear 10 is equal to the width of the ferrite tray 3;

[0037] When working, by driving the first gear 10 to rotate, since the first gear 10 is an incomplete gear, the first gear 10 will not mesh with the rack 12 when it rotates at the beginning, so it will remain in place. When the first gear 10 rotates, the first connecting frame 7 will be pulled to slide upward through the connecting rod 11. When the first gear 10 rotates ninety degrees, the connecting rod 11 drives the four baffles 8 to move to the position above the ferrite tray 3 through the first connecting frame 7; at this time, as the first gear 10 continues to rotate, the teeth on the first gear 10 begin to mesh with the rack 12, and the first gear 10 moves forward along the rack 12. When the first gear 10 moves forward, it will drive the sliding frame 9 to move forward, and the sliding frame 9 drives the first connecting frame 7 and the four baffles 8 to move forward; when the sliding frame 9 and the first connecting frame 7 move forward by the width of a ferrite tray 3, the first gear 10 is just disengaged from the rack 12. As the first gear 10 continues to rotate, the connecting rod 11 finally slowly drives the first connecting frame 7 and the four baffles 8 to move downward.

[0038] As a further solution of the present invention, the driving mechanism includes a motor 13, the motor 13 is located outside the furnace body 2 and the motor 13 is fixedly connected to the furnace body 2; the rear end of the output shaft of the motor 13 is fixedly connected to a telescopic rod 14, the telescopic end of the telescopic rod 14 is fixedly connected to a first bevel gear 15, the first bevel gear 15 is rotatably connected to the sliding frame 9 and the first bevel gear 15 is meshed with a second bevel gear 16, and the second bevel gear 16 is fixedly connected to the first gear 10;

[0039] During operation, the telescopic rod 14 can be driven to rotate by starting the motor 13. When the telescopic rod 14 rotates, the first bevel gear 15 is driven to rotate. The first bevel gear 15 drives the second bevel gear 16 to rotate. The second bevel gear 16 drives the first gear 10 to rotate.

[0040] As a further solution of the present invention, the material return mechanism includes a second cylinder 17, the second cylinder 17 is located outside the furnace body 2 and the second cylinder 17 is fixedly connected to the furnace body 2, and the telescopic end of the second cylinder 17 is fixedly connected to a push rod 18; a push block 19 is fixedly connected to the upper position of the rearmost side baffle 8, and the push block 19 is located behind the push rod 18; a torsion spring 20 is fixedly connected to the rearmost side baffle 8 at the connection position with the first connecting block, and the other end of the torsion spring 20 is fixedly connected to the first connecting frame 7;

[0042] During operation, when the ferrite tray 3 at the rear side of the furnace body 2 needs to be pushed out, the sealed door 4 at the rear side of the furnace body 2 is opened and the second cylinder 17 is started. The second cylinder 17 drives the push rod 18 to move backward. When the push rod 18 contacts the push block 19, it pushes the push block 19 to rotate. When the push block 19 rotates, it drives the baffle 8 at the rear side to rotate. When the baffle 8 at the rear side rotates, since the ferrite tray 3 is limited by two limit rods 21, the baffle 8 at the rear side will push the ferrite tray 3 at the rear side backward out of the furnace body 2 when it rotates; after the ferrite tray 3 at the rear side is pushed out, the push rod 18 is driven to reset, and at this time, the baffle 8 at the rear side will reset under the action of the torsion spring 20.
