DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Refer to the attached Figure 1 -Attached Figure 9 A segmented rotary roasting furnace includes a first furnace body 1 and a second furnace body 2. The first furnace body 1 and the second furnace body 2 have the same structure. In specific implementation, furnace bodies can be added in series as needed. A feeding hopper is provided at the feeding end of the furnace body at the head end for feeding materials, and a burner is provided at the discharging end of the furnace body at the end for heating the furnace so as to roast the materials in the furnace; and further includes: A connecting ring 6 is used to connect the first furnace body 1 and the second furnace body 2 end to end, and the cross section of the connecting ring 6 is a "T"-shaped structure; A temperature monitoring mechanism is used to monitor the temperature inside the first furnace body 1 and the second furnace body 2 in real time. The temperature monitoring mechanism is installed on the connecting ring 6; The inclination angle adjustment mechanism and the temperature monitoring mechanism form an electrical connection, and are used to adjust the inclination angles of the first furnace body 1 and the second furnace body 2 according to the temperature changes in the first furnace body 1 and the second furnace body 2, so as to control the material flow rate; A plurality of guide plates 9 are installed on the inner walls of the first furnace body 1 and the second furnace body 2 to change the flow path of the material; when the first furnace body 1 and the second furnace body 2 rotate, the guide plates 9 will be driven to rotate synchronously, so that the guide plates 9 can stir the material at the bottom of the first furnace body 1 and the second furnace body 2, change the flow path of the material, promote mutual mixing between the materials, and improve the uniformity of heating.

[0021] In this embodiment, the temperature monitoring mechanism includes a temperature sensor 7, which is fixedly mounted on the inner wall of the connecting ring 6, and the temperature sensor 7 is located at the upper part of the connecting ring 6. The inclination adjustment mechanism includes an adjusting plate 3 and a bottom plate 28. The adjusting plate 3 is rotatably mounted on one end close to the second furnace body 2 and the upper surface of the bottom plate 28. An electric telescopic rod 29 is rotatably mounted between the lower surface of the other end of the adjusting plate 3 and the upper surface of the bottom plate 28. The electric telescopic rod 29 and the temperature sensor 7 are controlled by a matching external controller. The control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and is only used without improvement. In addition, the present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail; the upper surface of the adjusting plate 3 is equipped with a driving mechanism for driving the first furnace body 1 and the second furnace body 2 to rotate forward and reverse.

[0022] The temperature inside the first furnace body 1 and the second furnace body 2 is monitored in real time by a temperature sensor 7 installed on the inner side of the connecting ring 6. The tilt angle of the first furnace body 1 and the second furnace body 2 is adjusted by the tilt adjustment mechanism according to the temperature change, thereby regulating the flow rate of the material in the first furnace body 1 and the second furnace body 2 (when the temperature is high, the tilt angle of the first furnace body 1 and the second furnace body 2 is increased to speed up the flow rate of the material; when the temperature is low, the opposite is true); The temperature inside the first furnace body 1 and the second furnace body 2 is monitored by the temperature sensor 7. When the temperature changes, the temperature sensor 7 will turn on the electric telescopic rod 29 through the external controller, so that the telescopic end of the electric telescopic rod 29 is extended or shortened, and the end of the adjustment plate 3 away from the second furnace body 2 is raised or lowered, thereby achieving the effect of adjusting the inclination angle of the first furnace body 1 and the second furnace body 2.

[0023] In this embodiment, the driving mechanism includes a door-shaped plate 20 fixedly mounted on the upper surface of the adjusting plate 3, and the outer peripheries of the first furnace body 1 and the second furnace body 2 are respectively fixedly mounted with a first driven gear 101 and a second driven gear 201, and the outer surfaces of the opposite sides of the door-shaped plate 20 are respectively rotatably mounted with a first driving gear 21 and a second driving gear 27 correspondingly meshed with the first driven gear 101 and the second driven gear 201, and the outer surface of the door-shaped plate 20 close to the first driving gear 21 is rotatably mounted with a reversing gear 22, which meshes with the first driving gear 21, and the outer surface of the other side of the door-shaped plate 20 is fixedly mounted with a stepping motor 23, and the output end of the stepping motor 23 passes through the outer surface of the door-shaped plate 20 and is fixedly mounted with a transmission shaft 24, and the transmission shaft 24 is fixedly mounted to the rotation center of the reversing gear 22, and the transmission shaft 24 and the rotation center of the second driving gear 27 are both fixedly mounted with a transmission pulley 25, and the outer surfaces of the two transmission pulleys 25 are provided with a transmission belt 26.

[0024] When the material is roasted, the transmission shaft 24 is driven to rotate by the stepping motor 23, so that the transmission shaft 24 drives the second driving gear 27 to rotate through the transmission pulley 25 and the transmission belt 26, so that the second driving gear 27 drives the second driven gear 201 meshing with it to rotate, thereby causing the second furnace body 2 to rotate forward; while the transmission shaft 24 rotates, it will also drive the reversing gear 22 to rotate, so that the reversing gear 22 drives the first driving gear 21 meshing with it to rotate, so that the first driving gear 21 drives the first driven gear 101 meshing with it to rotate, thereby causing the first furnace body 1 to reverse. Through the forward and reverse rotation of the first furnace body 1 and the second furnace body 2, the movement trajectory of the material in the furnace body can be made more complex and dispersed, ensuring that each material particle can contact the heat source and enhancing the roasting effect.

[0025] In this embodiment, a support assembly for supporting the first furnace body 1 and the second furnace body 2 is installed on the top of the adjustment plate 3, and the support assembly includes a plurality of retaining frames 4 fixedly installed on the upper surface of the adjustment plate 3. The first furnace body 1 and the second furnace body 2 are both arranged through the corresponding bottom retaining frames 4, and a plurality of support rollers 5 are evenly rotated and installed on the inner side of the retaining frames 4. The support rollers 5 are in contact with the outer sides of the first furnace body 1 and the second furnace body 2, and an annular groove is opened on the outer periphery of the first furnace body 1 and the second furnace body 2 near the support rollers 5, and the support rollers 5 are embedded in the annular groove.

[0026] When in use, the furnace body is supported by the retaining frame 4 and the supporting rollers 5 to ensure normal and stable rotation of the furnace body.

[0027] In this embodiment, a plurality of strip grooves 8 matching the guide plates 9 are equidistantly provided on the inner walls of the first furnace body 1 and the second furnace body 2 in the circumferential direction. The guide plates 9 are slidably installed on the inner walls of the strip grooves 8. A gravity adjustment mechanism for adjusting the protruding height of the guide plates 9 is installed inside the first furnace body 1 and the second furnace body 2. The gravity adjustment mechanism includes a transverse plate 10 fixedly installed on the inner wall of the first furnace body 1. A support rod 11 is fixedly installed on the outer surface of the transverse plate 10 near the feeding end of the first furnace body 1. A sleeve 12 is provided on the outer surface of the support rod 11. A connecting rod 13 is rotatably installed between the outer surface of the sleeve 12 and the plurality of guide plates 9. A toggle assembly is installed between the support rod 11 and the sleeve 12. The toggle assembly includes a support ring 14 rotatably installed on the outer periphery of the sleeve 12. A limiting groove is provided on the outer periphery of the sleeve 12, and the support ring 14 is rotatably installed with the inner wall of the limiting groove. The position of the support ring 14 is limited by the limiting groove, so that the support ring 14 can drive the sleeve 12 to move synchronously. A guide column 15 is fixedly installed on the outer periphery of the support ring 14, and a swivel 16 is rotatably installed on the outer periphery of the support rod 11. Two limiting rings are fixedly installed on the outer surface of the support rod 11 near the two sides of the swivel 16, and the axial position of the swivel 16 can be limited by the two limiting rings. A bending frame 17 is rotatably installed on the bottom of the swivel 16, and a counterweight 19 is fixedly installed on the bottom end of the bending frame 17. A guide groove 18 matching the guide column 15 is penetrated by the outer surface of the bending frame 17 above its rotation center, and the guide column 15 is slidably installed on the inner wall of the guide groove 18.

[0028] When the temperature of the first furnace body 1 and the second furnace body 2 is high and the inclination angle needs to be increased, the counterweight block 19 installed inside the first furnace body 1 and the second furnace body 2 will drive the bending frame 17 to produce relative deflection under the action of its own gravity, so that the guide groove 18 provided on the bending frame 17 cooperates with the guide column 15 and the support ring 14 to push the sleeve 12 toward the feeding end of the furnace body, so that the sleeve 12 can push the guide plate 9 toward the inside of the strip groove 8 through the connecting rod 13, so as to reduce the protruding height of the guide plate 9, thereby reducing the disturbing effect of the guide plate 9 on the material, accelerating the flow speed of the material inside the first furnace body 1 and the second furnace body 2, shortening the roasting time of the material, and avoiding the overheating temperature inside the first furnace body 1 and the second furnace body 2 causing overburning of the material; when the temperature of the first furnace body 1 and the second furnace body 2 drops and the inclination angle decreases, the above steps are reversed to increase the protruding height of the guide plate 9, and the disturbing effect on the material will also increase accordingly, extending the roasting time of the material and ensuring the roasting effect of the material.

[0029] From the above description, it can be seen that the above embodiment of the present invention achieves the following technical effects: when in use, the material to be roasted is put into the first furnace body 1 for roasting, and the roasted material is discharged from the discharge end of the second furnace body 2; When the material is roasting, the transmission shaft 24 is driven to rotate by the stepping motor 23, so that the transmission shaft 24 drives the second driving gear 27 to rotate through the transmission pulley 25 and the transmission belt 26, so that the second driving gear 27 drives the second driven gear 201 meshing with it to rotate, thereby causing the second furnace body 2 to rotate forward; while the transmission shaft 24 rotates, it will drive the reversing gear 22 to rotate, so that the reversing gear 22 drives the first driving gear 21 meshing with it to rotate, so that the first driving gear 21 drives the first driven gear 101 meshing with it to rotate, thereby causing the first furnace body 1 to reverse. Through the forward and reverse rotation of the first furnace body 1 and the second furnace body 2, the movement trajectory of the material in the furnace body can be made more complex and dispersed, ensuring that each material particle can contact the heat source, thereby enhancing the roasting effect; The temperature inside the first furnace body 1 and the second furnace body 2 is monitored in real time by a temperature sensor 7 installed on the inner side of the connecting ring 6. The tilt angle of the first furnace body 1 and the second furnace body 2 is adjusted by the tilt adjustment mechanism according to the temperature change, thereby regulating the flow rate of the material in the first furnace body 1 and the second furnace body 2 (when the temperature is high, the tilt angle of the first furnace body 1 and the second furnace body 2 is increased to speed up the flow rate of the material; when the temperature is low, the opposite is true); When the temperature of the first furnace body 1 and the second furnace body 2 is high and the inclination angle needs to be increased, the counterweight block 19 installed inside the first furnace body 1 and the second furnace body 2 will drive the bending frame 17 to produce relative deflection under the action of its own gravity, so that the guide groove 18 provided on the bending frame 17 cooperates with the guide column 15 and the support ring 14 to push the sleeve 12 toward the feeding end of the furnace body, so that the sleeve 12 can push the guide plate 9 toward the inside of the strip groove 8 through the connecting rod 13, so as to reduce the protruding height of the guide plate 9, thereby reducing the disturbing effect of the guide plate 9 on the material, accelerating the flow speed of the material inside the first furnace body 1 and the second furnace body 2, shortening the material roasting time, and avoiding the overheating temperature inside the first furnace body 1 and the second furnace body 2 causing overburning of the material; When the temperature of the first furnace body 1 and the second furnace body 2 drops and the inclination angle decreases, the above steps are reversed to increase the protruding height of the guide plate 9, which will increase the turbulence effect on the material, extend the roasting time of the material, and ensure the roasting effect of the material.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
