Description

Technical Field

[0001] This invention belongs to the field of tryptophan crystal processing technology, and in particular relates to a stirring structure for drying tryptophan crystals. Background Technology

[0002] Tryptophan crystal drying refers to the process of treating tryptophan crystals using specific drying equipment and processes. By utilizing environments such as hot air and vacuum, combined with structures such as agitation and airflow dispersion, the crystals are brought into full contact with the heat medium to quickly remove moisture. At the same time, the design of graded and circulating drying ensures the uniformity of drying. It is a key link in the production and purification of tryptophan to ensure product quality and stability.

[0003] In tryptophan crystal drying equipment, the rotating agitator inside the dryer creates a strong rotating airflow. However, the discharge hopper is mostly a fixed structure. When receiving material, changes in the crystal discharge flow rate and agglomeration state can easily lead to material deviation or accumulation, affecting collection efficiency. When not receiving material, the fixed hopper occupies space and creates cleaning dead zones, where residual crystals can become damp and deteriorate, increasing the difficulty of equipment maintenance. Therefore, we need to design an agitator structure for tryptophan crystal drying that can rotate the discharge hopper. When receiving material, the angle can be flexibly adjusted to precisely match the discharge trajectory of the tryptophan crystals, avoiding material deviation and accumulation, ensuring smooth collection. When not receiving material, the hopper can be retracted, reducing space occupation, eliminating cleaning dead zones, facilitating equipment maintenance and residue cleaning, improving the efficiency and cleanliness of the post-drying processing, and contributing to a more stable and efficient tryptophan crystal production process. Utility Model Content

[0004] The purpose of this invention is to provide a stirring structure for drying tryptophan crystals, which has the advantages of a rotatable receiving hopper that can flexibly adjust the angle, accurately adapt to the discharge trajectory when receiving material, and retract to reduce space occupation and cleaning dead corners when not receiving material, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A stirring structure for drying tryptophan crystals includes a support frame fixedly connected to the right side of the dryer. A receiving hopper is provided on the top of the support frame, and the receiving hopper is located on the right side of the dryer's discharge port. A fixed shell is fixedly connected to the right side of the support frame. A rotating rod is provided at the bottom of the inner cavity of the fixed shell. The rotating rod passes through the front and rear sides of the fixed shell and is rotatably connected to the fixed shell through a rotating shaft. A rotating plate is fixedly connected to the front side of the rotating rod. A large gear is fixedly connected to the rear side of the rotating rod. A rotating rod is provided at the top of the inner cavity. The rotating rod passes through the front and rear sides of the fixed shell and is rotatably connected to the fixed shell through a rotating shaft. A small gear is fixedly connected to the rear side of the rotating rod. The small gear meshes with the large gear. A cylinder is provided on the front side of the fixed shell. Connecting side plates are fixedly connected to both the front and rear sides of the rotating rod. The two facing side plates are fixedly connected to the receiving hopper.

[0006] Preferably, the end of the rotating plate away from the rotating rod is rotatably connected to a rotating block via a rotating shaft.

[0007] Preferably, a connecting block is fixedly connected to the bottom of the rotating block, and the output end of the cylinder is fixedly connected to the connecting block.

[0008] Preferably, a support member is fixedly connected to the front side of the bottom of the fixed shell, and the cylinder is mounted on the top of the support member.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model dries tryptophan crystals using a dryer. Through the coordinated use of a rotating rod, a rotating block, and a large gear, the rotating rod drives the two connecting side plates to rotate, thereby allowing the receiving hopper to be adjusted to a suitable angle on the right side of the dryer.

[0023] In the following description, embodiments of the stirring structure for drying tryptophan crystals according to the present invention will be described with reference to the accompanying drawings.

[0024] Figure 1-6This invention illustrates an embodiment of a stirring structure for drying tryptophan crystals, comprising a support frame 2 fixedly connected to the right side of a dryer 1. A receiving hopper 3 is located at the top of the support frame 2, to the right of the dryer 1's outlet. A fixed housing 4 is fixedly connected to the right side of the support frame 2. A rotating rod 5 is located at the bottom of the inner cavity of the fixed housing 4, extending through the front and rear sides of the fixed housing 4 and rotatably connected to it via a rotating shaft. A rotating plate 6 is connected to the front of the rotating rod 5, and the rotating plate 6 is located away from the rotating shaft. One end of rod 5 is rotatably connected to a rotating block 7 via a rotating shaft. A large gear 9 is fixedly connected to the rear side of the rotating rod 5. A rotating rod 10 is provided at the top of the inner cavity. The rotating rod 10 extends through the front and rear sides of the fixed housing 4 and is rotatably connected to the fixed housing 4 via a rotating shaft. A small gear 11 is fixedly connected to the rear side of the rotating rod 10, and the small gear 11 meshes with the large gear 9. A cylinder 13 is provided at the front side of the fixed housing 4. A connecting block 8 is fixedly connected to the bottom of the rotating block 7. The output end of the cylinder 13 is fixedly connected to the connecting block 8. The design ensures that the connecting block 8 guides the rotating block 7 during rotation, guaranteeing a stable position for the rotating block 7 as it drives the rotating plate 6, thus improving the stability of the rotating block 7. A support member 12 is fixedly connected to the front bottom of the fixed shell 4, and a cylinder 13 is mounted on top of the support member 12. Connecting side plates 15 are fixedly connected to both the front and rear sides of the rotating rod 10. The opposite side of the two connecting side plates 15 is fixedly connected to the receiving hopper 3. Two symmetrical connecting sleeves 14 are fixedly connected to both the front and rear sides of the fixed shell 4. The connecting sleeves 14 are rotatably connected to the rotating rod 5 and the rotating rod 10. Circular grooves for the rotating rod 5 and the dryer 1 to rotate are provided on both the front and rear sides of the fixed shell 4. The connecting sleeves 14 limit the rotation of the rotating rod 5 and the rotating rod 10 during rotation, ensuring that the rotating rod 5 and the rotating rod 10 do not wobble when rotating within the inner cavity of the fixed shell 4, thus improving the stability of the rotating rod 5 and the rotating rod 10.

[0025] Working Principle: In use, the dryer 1 serves as the main equipment for drying tryptophan crystals. The support frame 2 is used to stably support the dryer 1 and the subsequent receiving structure. During operation, hot air enters the bottom of the dryer 1 tangentially. The motor drives the stirring structure inside the dryer to rotate, creating a strong rotating airflow. Tryptophan crystals are fed into the dryer 1 through the feeding device. Under the action of the high-speed rotating stirring structure, they are rapidly dispersed by impact, friction, and shear force. The dispersed crystals come into full contact with the hot air, and the heat transfer causes the moisture in the crystals to vaporize. The water vapor flows with the hot airflow, and the dehydrated dry material rises with the hot airflow. After being processed by the grading structure inside the dryer, large particles are retained, and small particles are discharged from the center of the ring. Large pieces of material that are not completely dried or thrown against the wall fall back to the bottom and are crushed and dried again by the stirring structure. After the drying process is completed, the tryptophan crystals are discharged from the outlet of the dryer 1. When receiving material, cylinder 13 is activated. The cylinder 13 drives the rotating block 7 to move through the connecting block 8. The rotating block 7 is linked to the rotating plate 6, causing the rotating rod 5 to rotate inside the fixed shell 4. The large gear 9 on the rotating rod 5 rotates synchronously. Because the large gear 9 meshes with the small gear 11, it will drive the rotating rod 10 to rotate. The connecting sleeves 14 at both ends of the rotating rod 10 ensure its stable rotation. The rotating rod 10, through the fixedly connected connecting side plate 15, drives the receiving hopper 3 to rotate and adjust its angle so that it is accurately aligned with the discharge port of the dryer 1, adapting to the discharge trajectory of tryptophan crystals, avoiding material deviation and accumulation, and ensuring smooth collection. When not receiving material, the cylinder 13 is controlled in reverse, and the receiving hopper 3 can be recycled to a space-saving position, eliminating cleaning dead corners and facilitating equipment maintenance and residue cleaning. Throughout the process, the support 12 firmly supports the cylinder 13, and the connecting sleeve 14 limits the rotation of the rotating rod 5 and the rotating rod 10, ensuring the stable operation of the structure and ultimately realizing the flexible adjustment of the angle of the receiving hopper.

[0026] In summary, the stirring structure for drying tryptophan crystals uses dryer 1 to dry the crystals. Through the coordinated use of rotating rod 5, rotating block 7, and large gear 9, rotating rod 10 drives the two connecting side plates 15 to rotate, thereby allowing the receiving hopper 3 to be adjusted to a suitable angle on the right side of dryer 1. This achieves the purpose of flexibly adjusting the angle of the rotating receiving hopper, accurately matching the discharge trajectory when receiving material, and retracting it when not receiving material to reduce space occupation and clean dead corners.
