[0038] The spiral drum 2 transports the crushed and screened material to the connecting box 8. The calcining furnace 18 is used for heating the material.
[0039] Specifically, the axis of the spiral cylinder 2 is inclined. The height of the end of the spiral cylinder 2 closer to the connecting box 8 is higher than the height of the end farther away from the connecting box 8.

[0042] Specifically, the crushing and screening device includes: a feed hopper 5, a crushing roller 6, and a screen plate 7.
[0043] The feed hopper 5 is fixedly installed at the end of the spiral cylinder 2 away from the connecting box 8, and the feed hopper 5 is in communication with the inner cavity of the spiral cylinder 2.
[0044] The crushing roller 6 is rotatably mounted inside the feed hopper 5. The crushing roller 6 is used to crush the raw materials entering the feed hopper 5.
[0045] The screen plate 7 is fixedly installed inside the feed hopper 5, and is located below the crushing roller 6. The screen plate 7 is inclined, and the inclination direction of the screen plate 7 is the same as that of the spiral drum 2. A discharge chute is provided on the feed hopper 5, and the discharge chute is located on the side wall of the feed hopper 5 near the side with the lower height of the screen plate 7. The lower end of the screen plate 7 protrudes outward from the feed hopper 5.
[0046] Please see the appendix Figure 2 When the material entering the feed hopper 5 is crushed by the crushing roller 6, the crushed material falls onto the screen plate 7 and rolls on the screen plate 7. During the rolling process, the small crushed particles fall into the screw drum 2 through the screening action of the screen plate 7. Larger, incompletely crushed materials are discharged from the feed hopper 5 through the discharge chute.
[0047] A first motor 3 is fixedly mounted on the side wall of the spiral cylinder 2 away from the connecting box 8.

[0051] Specifically, the feeding device includes two rotating plates 10. The two rotating plates 10 are located on the front and rear side walls of the connecting box 8, respectively.
[0052] The rotating plate 10 is rotatably connected to the connecting box 8. Furthermore, two second motors 9 are fixedly installed on the side wall of the connecting box 8. The two second motors 9 are respectively fixed to the front and rear side walls of the connecting box 8. The rotating plate 10 is fixedly connected to the output shaft of the corresponding second motor 9. When the second motor 9 is started, it drives the rotating plate 10 to rotate.
[0053] A push plate 17 is rotatably mounted between the two rotating plates 10, and a drive assembly is installed between the rotating plates 10 and the push plate 17 to drive the push plate 17 to move along a rectangular trajectory.
[0054] As an optional embodiment, please refer to the appendix. Figure 3 and attached Figure 4 The driving assembly includes: a sliding rod 11, a connecting plate 13, a connecting sleeve 14, a limiting rod 15, and a limiting plate 16.
[0055] Specifically, two sliding rods 11 are provided. Each sliding rod 11 corresponds to one of the rotating plates 10. The axis of each sliding rod 11 is perpendicular to the axis of the output shaft of the second motor 9, and the sliding rod 11 is slidably connected to the corresponding rotating plate 10.
[0056] Two connecting plates 13 are provided. Each connecting plate 13 corresponds one-to-one with a sliding rod 11. Both ends of the sliding rod 11 pass through the rotating plate 10 and are located on the outer side of the corresponding rotating plate 10. Each connecting plate 13 is fixedly installed at one end of the corresponding sliding rod 11. A spring 12 is sleeved on the sliding rod 11; one end of the spring 12 is fixed to the connecting plate 13, and the other end of the spring 12 is fixed to the rotating plate 10.
[0057] Two connecting sleeves 14 are provided, each corresponding to one of the connecting plates 13. The connecting sleeves 14 and the corresponding connecting plates 13 are rotatably connected. The axis of rotation between the connecting sleeves 14 and the connecting plates 13 is parallel to the axis of the output shaft of the second motor 9.
[0058] The push plate 17 is fixedly installed between the two connecting sleeves 14.
[0059] Two limiting plates 16 are provided, each corresponding to one of the connecting sleeves 14. The limiting plates 16 and the corresponding connecting sleeves 14 are vertically slidably connected.
[0060] Two limiting rods 15 are provided, each corresponding to one of the limiting plates 16. The axis of the limiting rod 15 is set in the horizontal direction. The limiting rod 15 is fixedly installed in the connecting box 8. The limiting rod 15 and the limiting plate 16 are slidably connected.
[0061] When the second motor 9 drives the axis of the sliding rod 11 to rotate vertically via the rotating plate 10 and the connecting plate 13 is positioned above, the lower end of the limiting plate 16 abuts against the bottom wall of the connecting box 8. The end of the limiting rod 15 near the calcining furnace 18 abuts against the side wall of the connecting box 8. At this time, the push plate 17 is located on the limiting plate 16 near the end of the limiting rod 15, and the spring 12 is in a state of compression and deformation.
[0062] When the second motor 9 drives the rotating plate 10 to rotate counterclockwise, the rotating plate 10 and the connecting plate 13 will cause the connecting sleeve 14 to move away from the calcining furnace 18 along the limiting rod 15. That is, the push plate 17 moves away from the calcining furnace 18. During this process, the sliding rod 11 drives the connecting plate 13 to move closer to the rotating plate 10, and the spring 12 gradually returns to its original state. At the same time, due to the pressure of the spring 12, the connecting sleeve 14 does not move downward along the limiting plate 16.
[0063] When the second motor 9 drives the rotating plate 10 to rotate counterclockwise until the axis of the sliding rod 11 is parallel to the axis of the limiting rod 15, the connecting plate 13 moves to the position furthest from the rotating plate 10. As the second motor 9 continues to drive the rotating plate 10 to rotate counterclockwise, the connecting sleeve 14 moves downward along the limiting plate 16, i.e., the push plate 17 moves downward. Simultaneously, the connecting plate 13 moves again towards the rotating plate 10. The spring 12 is compressed and deformed again.
[0064] When the second motor 9 drives the rotating plate 10 to rotate counterclockwise until the axis of the sliding rod 11 is perpendicular to the axis of the limiting rod 15, the push plate 17 moves to its lowest displacement position. At this time, the connecting plate 13 is directly below the rotating plate 10. When the second motor 9 drives the rotating plate 10 to continue rotating counterclockwise, the rotating plate 10 and the connecting plate 13 will drive the connecting sleeve 14 to move along the limiting rod 15 towards the calcining furnace 18. That is, the push plate 17 moves towards the calcining furnace 18. During this process, the sliding rod 11 drives the connecting plate 13 to move towards the rotating plate 10, and the spring 12 gradually returns to its original state. At the same time, due to the pressure of the spring 12, the connecting sleeve 14 does not move upward along the limiting plate 16.
[0065] When the second motor 9 drives the rotating plate 10 to rotate counterclockwise until the axis of the sliding rod 11 is parallel to the axis of the limiting rod 15 again, the connecting plate 13 moves to the position furthest from the rotating plate 10. As the second motor 9 continues to drive the rotating plate 10 to rotate counterclockwise, the connecting sleeve 14 moves upward along the limiting plate 16, i.e., the push plate 17 moves upward. Simultaneously, the connecting plate 13 moves again towards the rotating plate 10. The spring 12 is compressed and deformed again.
[0066] At this point, the cycle of the pusher plate 17's movement is complete. When the pusher plate 17 is at its lowest displacement position, it moves along the limiting rod 15 towards the calcining furnace 18, pushing the material in the connecting box 8 towards the calcining furnace 18. When the pusher plate 17 is at its highest displacement position, it moves along the limiting rod 15 away from the calcining furnace 18, disengaging from the material in the connecting box 8 and unable to push the material in the connecting box 8.
[0067] As an alternative embodiment, two sets of electric telescopic rods can be installed on the push plate 17, and the electric telescopic rods are slidably connected to the connecting box 8. One set of electric telescopic rods has its axis arranged vertically, and the other set has its axis arranged horizontally. The telescopic ends of the electric telescopic rods are all fixedly connected to the push plate 17. A vertical groove is formed on the left side wall of the connecting box 8, and a horizontal groove is formed on the upper side wall of the connecting box 8. The electric telescopic rods with their axes arranged vertically are slidably connected to the horizontal grooves, and the electric telescopic rods with their axes arranged horizontally are slidably connected to the vertical grooves.
[0068] Intermittent activation of the electric telescopic rod can also move the pusher plate 17 along a rectangular trajectory. Specifically, extending the electric telescopic rod located in the horizontal slot moves the pusher plate 17 downwards. Extending the electric telescopic rod located in the horizontal slot moves the pusher plate 17 downwards. Extending the electric telescopic rod located in the vertical slot moves the pusher plate 17 closer to the calcining furnace 18. Re-activating the electric telescopic rod located in the horizontal slot shortens the pusher plate 17 upwards. Shortening the electric telescopic rod located in the vertical slot moves the pusher plate 17 away from the calcining furnace 18. The pusher plate 17 moves along a rectangular trajectory using the above method.
[0069] The calcining furnace 18 is equipped with a heating device.
[0070] Specifically, the heating device includes: a gas pipe 20, a third motor 21, and a heating rod 22.
[0071] The calcining furnace 18 contains a rotating shaft that is coaxially mounted inside. Multiple heating rods 22 are provided. The axes of the heating rods 22 are arranged radially along the calcining furnace 18, and the heating rods 22 are evenly distributed and fixedly mounted on the rotating shaft.
[0072] The third motor 21 is fixedly installed on the calcining furnace 18, and the output shaft of the third motor 21 is fixedly connected to the rotating shaft.
[0073] The gas pipe 20 is installed on the side wall of the calcining furnace 18, and the gas pipe 20 is connected to the inner cavity of the calcining furnace 18.
[0074] Starting the third motor 21 and heating rod 22 allows the heating rod 22 to stir the material inside the calcining furnace 18 during the heating process, resulting in more uniform heating. Introducing inert gas into the calcining furnace 18 through the gas pipe 20 prevents oxygen and other gases from reacting with the material during heating, thus improving reaction quality.
[0075] The specific operating principle of this application is as follows:
[0076] The material is poured into the feed hopper 5. The crushing roller 6 is started and rotates to crush the material into small pieces. The crushed material falls onto the screen plate 7. Unqualified material moves out of the feed hopper 5 through the inclined screen plate 7, while qualified material passes through the screen plate 7 and enters the screw drum 2.
[0077] The first motor 3 is started, which drives the conveyor rod 4 to rotate. The conveyor rod 4 conveys the material evenly. The material falls into the connecting box 8 through the first discharge port.
[0078] When the second motor 9 is started, and the axis of the sliding rod 11 is rotated vertically via the rotating plate 10 and the connecting plate 13 is positioned above, the lower end of the limiting plate 16 abuts against the bottom wall of the connecting box 8. The end of the limiting rod 15 near the calcining furnace 18 abuts against the side wall of the connecting box 8. At this time, the push plate 17 is located on the limiting plate 16 near the end of the limiting rod 15, and the spring 12 is in a compressed and deformed state.
[0079] When the second motor 9 drives the rotating plate 10 to rotate counterclockwise, the rotating plate 10 and the connecting plate 13 will cause the connecting sleeve 14 to move away from the calcining furnace 18 along the limiting rod 15. That is, the push plate 17 moves away from the calcining furnace 18. During this process, the sliding rod 11 drives the connecting plate 13 to move closer to the rotating plate 10, and the spring 12 gradually returns to its original state. At the same time, due to the pressure of the spring 12, the connecting sleeve 14 does not move downward along the limiting plate 16.
[0080] When the second motor 9 drives the rotating plate 10 to rotate counterclockwise until the axis of the sliding rod 11 is parallel to the axis of the limiting rod 15, the connecting plate 13 moves to the position furthest from the rotating plate 10. As the second motor 9 continues to drive the rotating plate 10 to rotate counterclockwise, the connecting sleeve 14 moves downward along the limiting plate 16, i.e., the push plate 17 moves downward. Simultaneously, the connecting plate 13 moves again towards the rotating plate 10. The spring 12 is compressed and deformed again.
[0081] When the second motor 9 drives the rotating plate 10 to rotate counterclockwise until the axis of the sliding rod 11 is perpendicular to the axis of the limiting rod 15, the push plate 17 moves to its lowest displacement position. At this time, the connecting plate 13 is directly below the rotating plate 10. When the second motor 9 drives the rotating plate 10 to continue rotating counterclockwise, the rotating plate 10 and the connecting plate 13 will drive the connecting sleeve 14 to move along the limiting rod 15 towards the calcining furnace 18. That is, the push plate 17 moves towards the calcining furnace 18. During this process, the sliding rod 11 drives the connecting plate 13 to move towards the rotating plate 10, and the spring 12 gradually returns to its original state. At the same time, due to the pressure of the spring 12, the connecting sleeve 14 does not move upward along the limiting plate 16.
[0082] When the second motor 9 drives the rotating plate 10 to rotate counterclockwise until the axis of the sliding rod 11 is parallel to the axis of the limiting rod 15 again, the connecting plate 13 moves to the position furthest from the rotating plate 10. As the second motor 9 continues to drive the rotating plate 10 to rotate counterclockwise, the connecting sleeve 14 moves upward along the limiting plate 16, i.e., the push plate 17 moves upward. Simultaneously, the connecting plate 13 moves again towards the rotating plate 10. The spring 12 is compressed and deformed again.
[0083] At this point, the cycle of the pusher plate 17's movement is complete. When the pusher plate 17 is at its lowest displacement position, it moves along the limiting rod 15 towards the calcining furnace 18, pushing the material in the connecting box 8 towards the calcining furnace 18. When the pusher plate 17 is at its highest displacement position, it moves along the limiting rod 15 away from the calcining furnace 18, disengaging from the material in the connecting box 8 and unable to push the material in the connecting box 8.
[0084] During the above process, the pusher plate 17 will not push the material away from the calcining furnace 18 during its movement, thus not affecting the feeding speed and improving work efficiency.
[0085] After the material is pushed into the calcining furnace 18, the sealing plate 19 is closed. The interior of the calcining furnace 18 is sealed, and the third motor 21 and heating rod 22 are started. The third motor 21 drives the heating rod 22 to rotate, stirring and heating the material inside the calcining furnace 18, allowing it to be fully dispersed and dried. At the same time, by injecting inert gas into the gas pipe 20, contact between the material and oxygen can be further avoided, reducing the possibility of elemental loss due to oxidation.
[0086] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
