Description

Technical Field

[0001] This invention relates to the field of roasting furnace technology, and more particularly to a segmented rotary roasting furnace. Background Technology

[0002] The segmented rotary roasting furnace is a common industrial piece of equipment widely used in high-temperature processing in industries such as ore, fertilizer, and building materials. Its main function is to uniformly heat materials during rotation, thereby achieving purposes such as drying, roasting, and calcination.

[0003] The existing segmented rotary kiln (announcement number: CN215638786U) has at least the following drawbacks: The above-mentioned patent has installed in-furnace burners in each segment of the rotary kiln, and the material is continuously processed through multiple segments of the rotary kiln, resulting in complete combustion, high thermal efficiency, and stable heating temperature, which is conducive to ensuring product quality; However, due to the lack of temperature monitoring structure in the multi-segment rotary kiln, the material flow rate cannot be adjusted in time when the temperature in the rotary kiln changes, which makes the material prone to local overheating or undercooling when the kiln temperature is too high or too low, affecting product quality. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a segmented rotary roasting furnace.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A segmented rotary roasting furnace includes a first furnace body and a second furnace body, the first furnace body and the second furnace body having the same structure, and further includes:

[0007] A connecting ring is used to rotatably connect the first furnace body and the second furnace body end to end. The cross-section of the connecting ring is a "T" shaped structure.

[0008] A temperature monitoring mechanism is used to monitor the temperature inside the first furnace body and the second furnace body in real time. The temperature monitoring mechanism is installed on the connecting ring.

[0009] The tilt angle adjustment mechanism is electrically connected with the temperature monitoring mechanism to adjust the tilt angle of the first furnace body and the second furnace body according to the temperature changes in the first furnace body and the second furnace body, so as to control the material flow rate.

[0010] A plurality of guide plates are installed on the inner walls of the first furnace body and the second furnace body to change the flow path of the material.

[0011] As a further embodiment of the present invention, the temperature monitoring mechanism includes a temperature sensor, which is fixedly installed on the inner wall of the connecting ring and is located at the upper part of the connecting ring.

[0012] As a further embodiment of the present invention, the tilt adjustment mechanism includes an adjustment plate and a base plate. One end of the adjustment plate near the second furnace body is rotatably mounted to the upper surface of the base plate. An electric telescopic rod is rotatably mounted between the lower surface of the other end of the adjustment plate and the upper surface of the base plate. The electric telescopic rod and the temperature sensor are controlled by a matching peripheral controller. A drive mechanism for driving the first and second furnace bodies to rotate forward and backward is mounted on the upper surface of the adjustment plate.

[0013] As a further embodiment of the present invention, the driving mechanism includes a portal plate fixedly mounted on the upper surface of the adjusting plate. A first driven gear and a second driven gear are fixedly mounted on the outer periphery of the first furnace body and the second furnace body, respectively. A first driving gear and a second driving gear, which mesh with the first driven gear and the second driven gear, are rotatably mounted on the outer surfaces of opposite sides of the portal plate, respectively. A reversing gear is rotatably mounted on the outer surface of the portal plate near the first driving gear. The reversing gear meshes with the first driving gear. A stepper motor is fixedly mounted on the outer surface of the other side of the portal plate. The output end of the stepper motor passes through the outer surface of the portal plate and is fixedly mounted with a drive shaft. The drive shaft is fixedly mounted with the rotation center of the reversing gear. A drive pulley is fixedly mounted on both the rotation center of the drive shaft and the second driving gear. A drive belt is sleeved on the outer surface of the two drive pulleys.

[0014] As a further embodiment of the present invention, a support assembly for supporting the first furnace body and the second furnace body is installed on the top of the adjusting plate. The support assembly includes a plurality of retainers fixedly installed on the upper surface of the adjusting plate. The first furnace body and the second furnace body are both disposed through the corresponding bottom retainer. A plurality of support rollers are uniformly rotatably installed on the inner side of the retainer.

[0015] As a further embodiment of the present invention, the inner walls of the first furnace body and the second furnace body are provided with a plurality of strip grooves that match the guide plate at equal intervals in the circumferential direction. The guide plate is slidably installed on the inner wall of the strip groove. The first furnace body and the second furnace body are both equipped with a gravity adjustment mechanism to adjust the protrusion height of the guide plate.

[0016] As a further embodiment of the present invention, the gravity adjustment mechanism includes a horizontal plate fixedly installed on the inner wall of the first furnace body, a support rod fixedly installed on the outer surface of the horizontal plate near the feeding end of the first furnace body, a sleeve sleeved on the outer surface of the support rod, a connecting rod rotatably installed between the outer surface of the sleeve and multiple guide plates, and an actuating component installed between the support rod and the sleeve.

[0017] As a further embodiment of the present invention, the actuating assembly includes a support ring rotatably mounted on the outer periphery of the sleeve, a guide post fixedly mounted on the outer periphery of the support ring, a rotating ring rotatably mounted on the outer periphery of the support rod, a bending frame rotatably mounted on the bottom of the rotating ring, a counterweight fixedly mounted on the bottom end of the bending frame, and a guide groove matching the guide post extending through the outer surface of the bending frame above its rotation center, wherein the guide post is slidably mounted on the inner wall of the guide groove.

[0018] As a further embodiment of the present invention, a limiting groove is formed on the outer periphery of the sleeve, and the support ring is rotatably installed on the inner wall of the limiting groove.

[0019] As a further embodiment of the present invention, two limiting rings are fixedly installed on the outer surface of the support rod near both sides of the rotating ring.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. By driving the first and second furnace bodies to rotate in both directions through the drive mechanism, the movement trajectory of the material in the furnace body can be made more complex and dispersed, ensuring that each material particle can come into contact with the heat source and enhancing the roasting effect;

[0022] 2. The temperature inside the first and second furnace bodies is monitored in real time by a temperature sensor installed inside the connecting ring. Based on temperature changes, the tilt angle adjustment mechanism adjusts the inclination angle between the first and second furnace bodies, thereby regulating the material flow rate within them (increasing the tilt angle at higher temperatures accelerates material flow; conversely, decreasing it at lower temperatures). This ensures more uniform material residence time and heating temperature within the furnace bodies, preventing localized overheating or undercooling that could affect product quality.

[0023] 3. When the temperature of the first and second furnace bodies is high and an increased tilt angle is required, the counterweights installed inside the first and second furnace bodies will cause the bending frame to deflect relatively under their own weight. This causes the guide grooves on the bending frame, together with the guide posts and support rings, to push the sleeve towards the feed end of the furnace body. The sleeve can then push the guide plate into the groove through the connecting rod, thereby reducing the protrusion height of the guide plate and reducing the turbulence effect of the guide plate on the material. This accelerates the flow rate of the material inside the first and second furnace bodies, shortens the roasting time of the material, and avoids overheating of the material due to excessive temperature inside the first and second furnace bodies.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] See attached document Figure 1 - Appendix 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 implementations, furnace bodies can be added in series as needed. A feeding hopper is provided at the feeding end of the first furnace body for feeding, and a burner for heating the material inside the furnace is provided at the discharging end of the second furnace body to roast the material inside the furnace; it also includes:

[0037] The connecting ring 6 is used to rotatably connect the first furnace body 1 and the second furnace body 2. The cross-section of the connecting ring 6 is a "T" shaped structure.

[0038] 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.

[0039] The tilt angle adjustment mechanism is electrically coordinated with the temperature monitoring mechanism to adjust the tilt angle 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.

[0040] Several 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, they will drive the guide plates 9 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 the mixing between the materials, and improve the uniformity of heating.

[0041] In this embodiment, the temperature monitoring mechanism includes a temperature sensor 7, which is fixedly installed on the inner wall of the connecting ring 6 and located at the upper part of the connecting ring 6. The tilt adjustment mechanism includes an adjustment plate 3 and a base plate 28. One end of the adjustment plate 3 near the second furnace body 2 is rotatably installed on the upper surface of the base plate 28. An electric telescopic rod 29 is rotatably installed between the lower surface of the other end of the adjustment plate 3 and the upper surface of the base plate 28. The electric telescopic rod 29 and the temperature sensor 7 are controlled by a matching peripheral controller. The control circuit can be easily programmed by those skilled in the art and is common knowledge in the field. It is only used and not improved. Furthermore, this invention is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail. A drive mechanism for driving the first furnace body 1 and the second furnace body 2 to rotate forward and backward is installed on the upper surface of the adjustment plate 3.

[0042] Temperature sensors 7 installed inside the connecting ring 6 monitor the temperature inside the first furnace body 1 and the second furnace body 2 in real time. Based on temperature changes, the tilt angle adjustment mechanism adjusts the tilt angle of the first furnace body 1 and the second furnace body 2, thereby regulating the flow rate of materials inside the first furnace body 1 and the second furnace body 2 (increasing the tilt angle of the first furnace body 1 and the second furnace body 2 when the temperature is high, and increasing the flow rate of materials; and vice versa when the temperature is low).

[0043] Temperature sensor 7 monitors the temperature inside the first furnace body 1 and the second furnace body 2. When the temperature changes, temperature sensor 7 will activate electric telescopic rod 29 through an external controller, causing the telescopic end of electric telescopic rod 29 to extend or shorten. This will raise or lower the end of adjustment plate 3 away from the second furnace body 2, thereby achieving the effect of adjusting the tilt angle of the first furnace body 1 and the second furnace body 2.

[0044] In this embodiment, the driving mechanism includes a portal plate 20 fixedly mounted on the upper surface of the adjusting plate 3. A first driven gear 101 and a second driven gear 201 are fixedly mounted on the outer periphery of the first furnace body 1 and the second furnace body 2, respectively. A first driving gear 21 and a second driving gear 27, which mesh with the first driven gear 101 and the second driven gear 201, are rotatably mounted on the outer surfaces of opposite sides of the portal plate 20. A reversing gear 22 is rotatably mounted on the outer surface of the portal plate 20 near the first driving gear 21. The reversing gear 22 meshes with the first driving gear 21. A stepper motor 23 is fixedly mounted on the outer surface of the other side of the portal plate 20. The output end of the stepper motor 23 passes through the outer surface of the portal plate 20 and is fixedly mounted with a transmission shaft 24. The transmission shaft 24 is fixedly mounted with the rotation center of the reversing gear 22. Transmission pulleys 25 are fixedly mounted on the rotation centers of the transmission shaft 24 and the second driving gear 27. Transmission belts 26 are sleeved on the outer surfaces of the two transmission pulleys 25.

[0045] During the roasting of materials, the stepper motor 23 drives the transmission shaft 24 to rotate, which in turn drives the second drive gear 27 to rotate via the transmission pulley 25 and the transmission belt 26. The second drive gear 27 then drives the second driven gear 201 meshing with it to rotate, thereby causing the second furnace body 2 to rotate forward. At the same time, the rotation of the transmission shaft 24 drives the reversing gear 22 to rotate, which in turn drives the first drive gear 21 meshing with it to rotate. The first drive gear 21 then drives the first driven gear 101 meshing with it to rotate, thereby causing the first furnace body 1 to rotate in reverse. By rotating the first furnace body 1 and the second furnace body 2 in both forward and reverse directions, the movement trajectory of the materials in the furnace body can be made more complex and dispersed, ensuring that each material particle can come into contact with the heat source and enhancing the roasting effect.

[0046] 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 adjusting plate 3. The support assembly includes multiple retainers 4 fixedly installed on the upper surface of the adjusting plate 3. The first furnace body 1 and the second furnace body 2 are both set through the corresponding bottom retainers 4. Multiple support rollers 5 are evenly rotatably installed on the inner side of the retainers 4. The support rollers 5 are in contact with the outer side of the first furnace body 1 and the second furnace body 2. The first furnace body 1 and the second furnace body 2 are provided with annular grooves near the outer periphery of the support rollers 5. The support rollers 5 are embedded in the annular grooves.

[0047] During use, the furnace body is supported by the retainer 4 and the support roller 5 to ensure the normal and stable rotation of the furnace body.

[0048] In this embodiment, the inner walls of the first furnace body 1 and the second furnace body 2 are each equidistantly provided with multiple strip-shaped grooves 8 that match the guide plates 9. The guide plates 9 are slidably installed on the inner walls of the strip-shaped grooves 8. The interiors of the first furnace body 1 and the second furnace body 2 are each equipped with a gravity adjustment mechanism to adjust the protrusion height of the guide plates 9. The gravity adjustment mechanism includes a horizontal 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 horizontal plate 10 near the feed end of the first furnace body 1. A sleeve 12 is sleeved 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 multiple guide plates 9. An actuating assembly is installed between the support rod 11 and the sleeve 12. The actuating assembly includes a support ring 14 rotatably installed on the outer periphery of the sleeve 12. A limiting groove is formed on the outer periphery of the sleeve 12. The support ring 14 is rotatably installed on 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 post 15 is fixedly installed on the outer periphery of the support ring 14. A rotating ring 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 rotating ring 16. The axial position of the rotating ring 16 can be limited by the two limiting rings. A bending frame 17 is rotatably installed at the bottom of the rotating ring 16. A counterweight 19 is fixedly installed at the bottom end of the bending frame 17. A guide groove 18 matching the guide post 15 is formed on the outer surface of the bending frame 17 above its rotation center. The guide post 15 is slidably installed on the inner wall of the guide groove 18.

[0049] When the temperature of the first furnace body 1 and the second furnace body 2 is high and the tilt angle needs to be increased, the counterweight 19 installed inside the first furnace body 1 and the second furnace body 2 will drive the bending frame 17 to deflect relatively under its own weight. This causes the guide groove 18 on the bending frame 17 to work with the guide column 15 and the support ring 14 to push the sleeve 12 towards the feed end of the furnace body. This allows the sleeve 12 to push the guide plate 9 into the strip groove 8 through the connecting rod 13, thereby reducing the protrusion height of the guide plate 9. This reduces the turbulence effect of the guide plate 9 on the material, accelerates the flow speed of the material inside the first furnace body 1 and the second furnace body 2, shortens the roasting time of the material, and avoids overheating of the material inside the first furnace body 1 and the second furnace body 2. When the temperature of the first furnace body 1 and the second furnace body 2 decreases and the tilt angle shrinks, the above steps are reversed to increase the protrusion height of the guide plate 9. The turbulence effect on the material will also increase accordingly, prolonging the roasting time of the material and ensuring the roasting effect of the material.

[0050] As can be seen from the above description, the above embodiments of the present invention achieve 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.

[0051] During the roasting of materials, the stepper motor 23 drives the transmission shaft 24 to rotate, which in turn drives the second drive gear 27 to rotate via the transmission pulley 25 and the transmission belt 26. The second drive gear 27 then drives the second driven gear 201 meshing with it to rotate, thereby causing the second furnace body 2 to rotate forward. At the same time, the rotation of the transmission shaft 24 drives the reversing gear 22 to rotate, which in turn drives the first drive gear 21 meshing with it to rotate. The first drive gear 21 then drives the first driven gear 101 meshing with it to rotate, thereby causing the first furnace body 1 to rotate in reverse. By rotating the first furnace body 1 and the second furnace body 2 in both forward and reverse directions, the movement trajectory of the materials in the furnace body can be made more complex and dispersed, ensuring that each material particle can come into contact with the heat source and enhancing the roasting effect.

[0052] Temperature sensors 7 installed inside the connecting ring 6 monitor the temperature inside the first furnace body 1 and the second furnace body 2 in real time. Based on temperature changes, the tilt angle adjustment mechanism adjusts the tilt angle of the first furnace body 1 and the second furnace body 2, thereby regulating the flow rate of materials inside the first furnace body 1 and the second furnace body 2 (increasing the tilt angle of the first furnace body 1 and the second furnace body 2 when the temperature is high, and increasing the flow rate of materials; and vice versa when the temperature is low).

[0053] When the temperature of the first furnace body 1 and the second furnace body 2 is high and the tilt angle needs to be increased, the counterweight 19 installed inside the first furnace body 1 and the second furnace body 2 will drive the bending frame 17 to deflect relatively under its own weight. This causes the guide groove 18 on the bending frame 17 to work with the guide column 15 and the support ring 14 to push the sleeve 12 towards the feed end of the furnace body. This allows the sleeve 12 to push the guide plate 9 into the strip groove 8 through the connecting rod 13, thereby reducing the protrusion height of the guide plate 9 and reducing the turbulence effect of the guide plate 9 on the material. This accelerates the flow speed of the material inside the first furnace body 1 and the second furnace body 2, shortens the roasting time of the material, and avoids the overheating temperature inside the first furnace body 1 and the second furnace body 2 from causing overburning of the material.

[0054] When the temperature of the first furnace body 1 and the second furnace body 2 decreases and the tilt angle decreases, the above steps are reversed to increase the protrusion height of the guide plate 9, which will also increase the turbulence effect on the material, prolong the roasting time of the material, and ensure the roasting effect of the material.

[0055] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
