Description

Technical Field

[0001] This utility model relates to the field of waste metal recycling technology, specifically a drying device for waste metal recycling. Background Technology

[0002] Scrap metal recycling mainly includes collection, sorting, crushing, cleaning (deoxidation), drying, and smelting. Crushing yields scrap metal blocks of a specific size.

[0003] The drying process involves using a drying device to dry scrap metal. Common drying methods include heating and ventilation. A common drying device is a drying drum, where scrap metal blocks are fed into the drum body and dried by heating. Some drying drums can also rotate, causing the material to move within the drum.

[0004] In the existing technology, the drying cylinder is a closed system that cannot feed or discharge materials during the drying process, which results in drying in batches each time. Moreover, the waste metal blocks are not evenly distributed along the length of the drying cylinder during the drying process, which means that the heat cannot be evenly and quickly removed from the surface of the waste metal blocks. Utility Model Content

[0005] The purpose of this invention is to provide a drying device for waste metal recycling to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying device for waste metal recycling, comprising a drying cylinder, a feeding cylinder, a feeding mechanism, and a base; The feeding mechanism is located at the feeding end of the feeding cylinder and is used to control the feeding port of the feeding mechanism to face directly upward; The discharge end of the feed cylinder is connected to the drying cylinder and is used to quantitatively feed waste metal into the drying cylinder; The drying cylinder is rotatably mounted on the base to adjust its tilt. The tilt of the drying cylinder and the weight of the scrap metal are used to control the scrap metal to pass through the drying cylinder in sections.

[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] See Figures 1-5 This utility model provides a technical solution: a drying device for waste metal recycling, including a drying cylinder 1, a feeding cylinder 2, a feeding mechanism 3 and a base 4; The feeding mechanism 3 is located at the feeding end of the feeding cylinder 2 and is used to control the feeding port of the feeding mechanism 3 to face directly upward; The discharge end of the feed cylinder 2 is connected to the drying cylinder 1 and is used to quantitatively convey waste metal into the drying cylinder 1. The drying cylinder 1 is rotatably mounted on the base 4 to adjust the inclination of the drying cylinder 1. The inclination of the drying cylinder 1 and the weight of the waste metal are used to control the waste metal to pass through the drying cylinder 1 in sections. The hot air flow inside the drying cylinder 1 carries away the moisture on the surface of the waste metal. The base 4 is equipped with a motor 5.

[0016] It should be noted that in the previous process, a pile of scrap metal blocks is conveyed to the inlet of the feeding mechanism 3. After the drying cylinder 1 rotates, the inclination of the inlet of the feeding mechanism 3 will change, resulting in a smaller projected area of ​​the inlet of the feeding mechanism 3 on the ground. Consequently, the previous process cannot accurately convey the scrap metal to the inlet of the feeding mechanism 3, and some scrap metal will fall down. However, by setting the feeding mechanism 3, the inlet of the feeding mechanism 3 can be controlled to face directly upward. For the feeding mechanism 3 with any inclination, its horizontal cross section of the inlet remains unchanged, ensuring that the scrap metal is stably conveyed into the feeding mechanism 3.

[0017] To prevent all the scrap metal from sliding directly into the drying cylinder 1 at once, and to avoid a large accumulation of scrap metal in one place, which would result in very small and difficult-to-adjust gaps between the scrap metal blocks, allowing only a small amount of hot air to pass through, leading to low drying efficiency, a controlled amount of scrap metal is fed into the drying cylinder 1 each time. This ensures that the gaps between the scrap metal blocks are within a controllable range, thereby improving drying efficiency. Rotary shafts 131 are located on both sides of the drying cylinder 1, and are rotatably mounted on a base 4. The base 4 provides support for the drying cylinder 1. A motor 5 is mounted on the base 4, and the output shaft of the motor 5 is connected to one of the rotating shafts 131, thereby controlling the tilt of the drying cylinder 1.

[0018] The scrap metal passes through the drying drum 1 in sections. "Sectional passage" means that after the scrap metal arrives at a certain section of the drying drum 1, it stays in that section for a period of time before entering the next section. This also serves to prevent the scrap metal from accumulating in any one section of the drying drum 1.

[0019] In one embodiment, the feeding mechanism 3 includes an inner material cylinder 30 and an outer material cylinder 31. The inner material cylinder 30 is a spherical shape with openings at the top and bottom. The inner material cylinder 30 includes an outer arc surface, on which sliders 34 are symmetrically arranged. The outer material cylinder 31 has symmetrically arranged grooves 32 inside. The outer material cylinder 31 is provided with a power component 33, which controls the sliders 34 to slide in the grooves 32. The sliders 34 drive the inner material cylinder 30 to rotate. The outer material cylinder 31 is located at the top of the feeding cylinder 2, and the inner material cylinder 30 is connected to the feeding cylinder 2.

[0020] This design is for reference. Figure 1-2The inclination range of the drying cylinder 1 is 0-90 degrees, and the inclination range of the inner material cylinder 30 is -45 to 45 degrees. The slider 34 is driven by the power component 33 to slide along the slide groove 32. The center of the slide groove 32 coincides with the center of the inner material cylinder 30. The inner material cylinder 30 rotates along the slide groove 32, thereby adjusting the angle between the upper opening of the inner material cylinder 30 and the upper opening of the outer material cylinder 31, so that the upper opening of the inner material cylinder 30 faces upwards at any angle of the drying cylinder 1.

[0021] In one embodiment, the discharge port of the feed cylinder 2 is provided with a baffle 6 for partially blocking the discharge port of the feed cylinder 2; the drying cylinder 1 includes an inner cylinder 10, and the inlet of the inner cylinder 10 is provided with a baffle 7 for partially blocking the inlet of the drying cylinder 1. When the unblocked parts of the feed cylinder 2 and the drying cylinder 1 coincide, the scrap metal enters the drying cylinder 1 from the feed cylinder 2.

[0022] This design is for reference. Figure 2 When the inner cylinder 10 rotates, it will drive the second baffle 7 to rotate synchronously. When the second baffle 7 and the first baffle 6 overlap and fit together, the discharge area of ​​the feed cylinder 2 is at its maximum. When the second baffle 7 and the first baffle 6 block the discharge area of ​​the feed cylinder 2 together, the discharge area of ​​the feed cylinder 2 is at its minimum, which is zero. As the second baffle 7 rotates, the discharge area of ​​the feed cylinder 2 will decrease from large to small and then increase again, and the discharge volume will correspondingly decrease from large to small and then increase again.

[0023] In one embodiment, the drying cylinder 1 further includes an outer cylinder 11, a power component 2 12, and several material segmentation components 13. The outer cylinder 11 is rotatably disposed at the discharge end of the feeding cylinder 2, and the inner cylinder 10 is rotatably disposed in the outer cylinder 11. An air inlet chamber 14 is provided between the inner cylinder 10 and the outer cylinder 11. The outer cylinder 11 is provided with a plurality of air inlets 15 and air outlets 16; Several material segmentation components 13 are arranged side by side inside the inner cylinder 10 to separate the scrap metal at different locations within the inner cylinder 10. The material segmentation component 13 includes a partition 130, a rotating shaft 131, a torsion spring, and a rotating plate 132. The partition 130 is located in the inner cylinder 10. The rotating shaft 131 is fixed on the rotating plate 132. The rotating shaft 131 is rotatably connected to the partition 130 through the torsion spring. After the partition 130 and the rotating plate 132 are spliced ​​together, they seal the cross section of the inner cylinder 10.

[0024] This design is for reference. Figure 2-3 and Figure 5On the cross-section of the inner cylinder 10, the area ratio of the baffle 130 and the rotating plate 132 is determined by the volume and weight of the scrap metal blocks to be conveyed. After determining the area ratio of the baffle 130 and the rotating plate 132, the equipment is installed and put into use. During use, the hot airflow enters the air inlet chamber 14 through the air inlet 15 and is discharged through the air outlet 16. In the air inlet chamber 14, heat is transferred to the inner cylinder 10 to dry the scrap metal. Regarding the material segmentation component 13, during the rotation of the inner cylinder 10, the partition plate 130 and the rotating plate 132 will rotate synchronously. During the rotation, when the partition plate 130 is below the rotating plate 132, scrap metal will accumulate at the partition plate 130; when the partition plate 130 is above the rotating plate 132, scrap metal will accumulate at the rotating plate 132. The torsion spring has a fixed bearing capacity, and the required torsion spring specifications are used when designing the equipment. When the scrap metal accumulated at the rotating plate 132 exceeds the bearing capacity of the torsion spring, the weight of the scrap metal will drive the rotating plate 132 to rotate, creating a gap between the rotating plate 132 and the inner cylinder 10, and the scrap metal will fall through the gap. After the excess scrap metal has fallen off, the elasticity of the torsion spring itself will drive the rotating plate 132 to rotate in the opposite direction and reset, and the rotating plate 132 will reconnect with the partition plate 130 and close. Several material segmentation components 13 are arranged in parallel in an inner cylinder 10, thereby dividing the inner cylinder 10 into several working spaces. When the excess scrap metal falls from one working space to the next working space, it will eventually fall out from the bottom of the inner cylinder 10. It can fall directly into the external collection bucket or directly onto the external conveyor belt. If the feeding of scrap metal to the feeding mechanism 3 is stopped, the last scrap metal in each working space of the inner cylinder 10 that has not exceeded the limit needs to be discharged. At this time, the discharge requires adjusting the tilt angle of the drying cylinder 1 so that the end of the drying cylinder 1 with the feeding mechanism 3 rotates upward. At this time, the tilt angle of the drying cylinder 1 increases. Alternatively, the drying cylinder 1 can be driven to swing back and forth by the forward and reverse rotation of the motor 35. The swing amplitude does not exceed 15 degrees. By swinging, the acceleration of the scrap metal is increased, and the force of the scrap metal hitting the rotating plate 132 is increased, thereby promoting the scrap metal to fall from the gap after pushing the rotating plate 132 to rotate.

[0025] The scrap metal is evenly distributed in each section of the working space. When the power component 12 drives the inner cylinder 10 to rotate, it will rotate under the action of centrifugal force, causing the scrap metal to be evenly distributed in the working space. Moreover, by adjusting the rotation speed of the inner cylinder 10 to control the centrifugal force from large to small, the position distribution of the scrap metal in the working space can be changed, thereby avoiding the scrap metal from piling up and sticking together, accelerating the heat transfer to the scrap metal, and quickly and evenly removing the moisture from the scrap metal, thus improving the efficiency of drying the scrap metal.

[0026] In one embodiment, the power component 33 includes a motor 330, a spur gear 331, and a rack 332. The rack 332 is located on the slider 34, and the motor 330 is located on the outer material cylinder 31. The output shaft of the motor 330 is connected to the spur gear 331, and the spur gear 331 meshes with the rack 332.

[0027] This design is for reference. Figure 4 The output shaft of motor 330 drives the spur gear 331 to rotate. The spur gear 331 meshes with the rack 332, which in turn drives the rack 332 to rotate. The rack 332 drives the slider 34 and the inner material cylinder 30 to rotate synchronously. Motor 330 can rotate in reverse and forward, thereby adjusting the tilt range of the inner material cylinder 30.

[0028] In one embodiment, the second power component 12 includes a second motor 120, a second spur gear 121, and an external gear ring 122. The second spur gear 121 is located at one end of the inner cylinder 10, and the second motor 120 is located on the outer cylinder 11. The output shaft of the second motor 120 is connected to the second spur gear 121, and the second spur gear 121 meshes with the external gear ring 122, thereby driving the inner cylinder 10 to rotate.

[0029] This design is for reference. Figure 3 The output shaft of motor 120 drives spur gear 121 to rotate. Spur gear 121 meshes with external gear ring 122, which in turn drives external gear ring 122 to rotate. External gear ring 122 drives inner cylinder 10 to rotate synchronously. The rotation of inner cylinder 10 provides centrifugal force for the waste metal inside.

[0030] In one embodiment, the inner cylinder 10 is provided with several through holes, and hot air enters the inner cylinder 10 through the air inlet chamber 14 to contact the scrap metal.

[0031] This design is for reference. Figure 3 The hot airflow enters the air inlet 14 through the air inlet 15, enters the inner cylinder 10 through the through hole, and directly transfers the heat to the scrap metal. Finally, it is discharged from the inlet, outlet or air outlet 16 of the inner cylinder 10.

If the specific posture changes, the directional indicators will also change accordingly.
