Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically to a material feeding mechanism for a low-carbon roasting device. Background Technology

[0002] In low-carbon roasting processes, the efficiency and stability of the material feeding stage have a crucial impact on the smooth progress of the entire roasting process and product quality. Traditional feeding devices are often simple in structure and single in function, making it difficult to meet the needs of modern low-carbon roasting production. During low-carbon roasting, depending on the different material characteristics and roasting process requirements, the material needs to be accurately fed to a designated height. However, most traditional feeding devices lack an effective lifting mechanism, or the lifting mechanism is complex to operate and has poor stability, making it difficult to achieve precise lifting and lowering of the feeding rack. This results in inaccurate material feeding positions, affecting the roasting effect and product quality. Therefore, a new feeding mechanism for low-carbon roasting devices is proposed to solve the above problems. Utility Model Content

Therefore, a feeding mechanism for a low-carbon roasting device is proposed.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] In the embodiments, by Figure 1-3 A feeding mechanism for a low-carbon roasting apparatus is provided, comprising a feeding base frame 1, with two rotating shafts 13 rotatably connected to the inner side of the feeding base frame 1, and wheels 2 fixedly connected to the outer sides of the two rotating shafts 13. A support rod 3 is fixedly connected to the left end of the feeding base frame 1, and a rotating seat 4 is fixedly connected to the bottom end of the support rod 3. A roller 5 is rotatably connected to the inner side of the rotating seat 4. A top frame 6 is fixedly connected to the top end of the feeding base frame 1, and a sliding sleeve 7 is slidably connected to the outer side of the top frame 6. A feeding frame 8 is fixedly connected to the right end of the sliding sleeve 7. A lifting mechanism 9 for lifting the feeding frame 8 is provided on the top frame 6, and a driving mechanism 10 for driving the two wheels 2 to rotate is provided on the feeding base frame 1.

[0016] With the above setup, the entire feeding mechanism, driven by the drive mechanism 10, moves along the track via two wheels 2, proceeding to below the feed inlet of the roasting furnace. The position of the mechanism is adjusted to ensure the discharge port of the feeding rack 8 is accurately aligned with the feed inlet of the roasting furnace. Rollers 5 at the bottom of the support rod 3 roll on the track or ground, providing stable support to the left end of the mechanism and ensuring smooth movement and positioning. After the mechanism is in place, the lifting mechanism 9 (likely a hydraulic cylinder, electric push rod, or chain lifting device) begins operation, driving the sliding sleeve 7 to slide upwards along the top frame 6. The sliding sleeve 7 drives the feeding rack 8 (usually a hopper or chute) fixed to it to rise synchronously, lifting it to the preset feeding height. Once the feeding rack 8 reaches the designated height, the material inside (such as roasting raw materials) begins to flow smoothly and accurately into the roasting furnace under gravity, completing the feeding process. After feeding is complete, the lifting mechanism 9 reverses its direction, driving the feeding rack 8 to descend to the initial transport position. Subsequently, the drive mechanism 10 restarts, moving the entire mechanism away to make way for the next work cycle or other equipment operations. Through the cooperation of the drive mechanism 10 and the lifting mechanism 9, the entire process of moving, positioning, lifting, and unloading the feeding mechanism is mechanized, significantly reducing manual intervention and physical labor, and improving production efficiency. The mechanism can move and position precisely, ensuring a tight connection between the outlet of the feeding rack 8 and the inlet of the roasting furnace. This "point-to-point" feeding method effectively reduces material spillage and dust escape, while minimizing the time and area of ​​the furnace door opening during feeding, which helps maintain stable temperature and atmosphere inside the furnace and reduces heat loss.

[0017] Reference Figure 1-3 The lifting mechanism 9 includes a mounting base 91. The top of the top frame 6 is fixedly connected to the mounting base 91. The top of the mounting base 91 is fixedly connected to the lifting motor 92. The output end of the lifting motor 92 is fixedly connected to the steering gear 93. The steering gear 93 is fixedly connected to the top of the mounting base 91. The output end of the steering gear 93 is fixedly connected to the lead screw 94. The outer side of the lead screw 94 is fixedly connected to the threaded sleeve 95. The threaded sleeve 95 is fixedly connected to the left end of the unloading frame 8. With the above structural setup, when the unloading rack 8 needs to be lifted, the lifting motor 92 starts. The output shaft of the lifting motor 92 begins to rotate, and the generated torque is directly transmitted to the steering gear 93 fixedly connected to it. The steering gear 93 (usually a 90-degree angle worm gear reducer or gearbox) has two main functions: reducing the input speed and increasing the output torque, making the lifting more powerful and smoother. The vertical rotation of the motor output is converted into the rotation of the horizontal lead screw 94. At this time, the horizontal lead screw 94 begins to rotate together with the output end of the steering gear 93. A threaded sleeve 95 (i.e., a nut) is fitted on the outside of the lead screw 94. Since the lead screw 94 is fixed to the mounting base 91 by bearings, it can only rotate and cannot move axially. According to the principle of threaded transmission, when the lead screw 94 rotates, the threaded sleeve 95 cannot rotate with the lead screw 94 due to the constraints of the unloading rack 8 and the sliding sleeve 7 (the sliding sleeve 7 is fitted on the top frame 6 and can only slide up and down, not rotate). Therefore, the rotational motion of the lead screw 94 is converted into the strictly linear up and down motion of the threaded sleeve 95. When the lead screw 94 rotates in a specific direction (e.g., clockwise), it pushes the threaded sleeve 95 upward. When the lead screw 94 rotates in the opposite direction (counterclockwise), it pushes the threaded sleeve 95 downward. The threaded sleeve 95 is fixedly connected to the left end of the unloading frame 8. Therefore, when the threaded sleeve 95 moves linearly upward or downward, it directly pushes or pulls the entire unloading frame 8 together. The right end of the unloading frame 8 is slidably connected to the top frame 6 via the sliding sleeve 7. This ensures that the unloading frame 8 remains stable throughout the entire lifting process, without swaying or deflection, and can only perform smooth vertical lifting.

[0018] Reference Figure 1-3 The drive mechanism 10 includes a drive motor 101. The top of the unloading base 1 is fixedly connected to the drive motor 101. The output end of the drive motor 101 is connected to the rear rotating shaft 13 through a first sprocket and chain transmission mechanism 102. A driven shaft 103 is rotatably connected to the unloading base 1. The driven shaft 103 is fixedly connected to the output end of the drive motor 101. The driven shaft 103 is connected to the front rotating shaft 13 through a second sprocket and chain transmission mechanism 104. With the above structural setup, the drive motor 101 starts, and its output end begins to rotate. Power is transmitted from the output end to two paths simultaneously: Path 1: directly driving the rear rotating shaft 13 via the first sprocket and chain transmission mechanism 102. Path 2: the output end simultaneously drives the driven shaft 103, which is fixed to it, to rotate together. The rotation of the driven shaft 103 transmits power to the front rotating shaft 13 via the second sprocket and chain transmission mechanism 104. Crucially, since both the front and rear rotating shafts 13 are driven by the same drive motor 101 and the same driven shaft 103, this ensures that the rotational speed and direction of the two rotating shafts 13 are completely synchronized. The synchronized rotation of the front and rear rotating shafts 13 drives the wheels 2 fixed to their outer sides to rotate together. The wheels 2 roll on the track or ground, thereby propelling the entire unloading mechanism smoothly forward or backward. The rotation direction of the motor can be changed by altering the power phase (for a three-phase motor) or polarity (for a DC motor) of the drive motor 101. When the motor rotates forward, the mechanism moves forward; when the motor rotates in reverse, the mechanism moves backward.

[0019] Reference Figure 1-3 The top of the unloading base frame 1 is fixedly connected to a counterweight platform 11; With the above structural arrangement, when the lifting mechanism 9 lifts and extends the fully loaded unloading rack 8, the center of gravity of the entire equipment shifts to the right (usually towards the roasting furnace), generating a huge overturning moment. The counterweight platform 11 is located at the left end of the unloading base frame 1 (on the side opposite to the direction of the unloading rack 8's extension). By installing heavy counterweights on it, it generates an anti-overturning moment in the opposite direction. These two moments balance each other, ensuring that the entire mechanism will not tip forward during lifting and unloading, which is the most important safety guarantee.

[0020] Reference Figure 1-3 The top frame 6 has handles 12 fixedly connected to both the front and rear ends; With the above structural design, during equipment installation, commissioning, or routine maintenance, maintenance personnel may need to slightly move or stabilize components such as the sliding sleeve 7 and the unloading rack 8. Directly pushing or pulling these components by hand may be unsafe or inconvenient. The handle 12 provides an ideal point of force application, facilitating precise manual adjustments.
