Description

Technical Field

[0001] This utility model relates to the field of salt drying, and in particular to a stable unloading device for a salt drying machine. Background Technology

[0002] In the salt production process, the drying bed is one of the key pieces of equipment, and the stability of its salt output directly affects the production efficiency, product quality, cost control, and stable operation of the entire production line in the subsequent packaging workshop. However, the current drying bed has a large fluctuation range in salt output, which makes it difficult to accurately control the dosage in the subsequent iodization process, thereby increasing the risk of substandard product quality. Utility Model Content

[0003] To address the shortcomings or deficiencies of the existing technology, this utility model provides a stable unloading device for a salt drying machine, which can uniformly discharge salt, making the salt output from the drying bed stable, thereby facilitating precise dosage in subsequent salt production processes and improving product quality.

[0004] The technical implementation scheme of this utility model is as follows: a stable unloading device for a salt drying machine, comprising a drying bed, a cold air inlet and two hot air inlets on the drying bed, a feed hopper and a discharge hopper fixedly connected to the drying bed, the drying bed being connected to both the feed hopper and the discharge hopper, a servo motor fixedly connected to the outer wall of the discharge hopper, a star-shaped propeller rotatably connected inside the discharge hopper, a bevel gear set between the output shaft of the servo motor and one end of the star-shaped propeller, the bevel gear set being located outside the discharge hopper, a rotating disk fixedly connected to the other end of the star-shaped propeller, the rotating disk being located outside the discharge hopper, a protruding column fixedly connected to the rotating disk, two fixed blocks fixedly connected to the outer wall of the discharge hopper, the two fixed blocks being symmetrically arranged, a sliding frame slidably connected between the two fixed blocks, a screen frame slidably connected inside the discharge hopper, the screen frame being fixedly connected to the sliding frame, and a scraper frame fixedly connected inside the discharge hopper, the scraper frame passing through the screen frame.

[0005] Optionally, the bevel gear set consists of a driving bevel gear and a transmission bevel gear. The driving bevel gear is fixedly connected to the output shaft of the servo motor, and the transmission bevel gear is fixedly connected to one end of the star-shaped propeller. The driving bevel gear meshes with the transmission bevel gear.

[0006] Optionally, the carriage has a straight groove, and the protrusion is located in the straight groove on the carriage.

[0007] Optionally, the screen frame is located above the star-shaped paddle.

[0008] Optionally, the top of the scraper frame contacts the screen frame.

[0009] The beneficial effects of this utility model are as follows: wet salt particles are fed into the drying bed through the feed hopper. After being dried in the drying bed, the wet salt particles enter the discharge hopper. The dry salt particles fall onto the screen frame. At the same time, the servo motor drives the star-shaped paddle to rotate, and the slide frame drives the screen frame to move horizontally back and forth. The horizontal back and forth movement of the screen frame screens the dry salt particles that fall onto the screen frame. The scraper frame continuously scrapes away the coarse salt particles that are blocking the screen frame, keeping the screen frame unobstructed and improving the screening efficiency. The sieved dry salt particles fall downward into the lower part of the discharge hopper. The rotation of the star-shaped paddle evenly discharges the dry salt particles in the lower part of the discharge hopper. In this way, the star-shaped paddle can stabilize the salt output of the drying bed, making the salt output of the drying bed discharge hopper uniform. At the same time, the screen frame screens out larger salt particles, which can prevent the salt particles from blocking the star-shaped paddle. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0017] Example 1 A stable unloading device for a salt drying machine, such as Figures 1-5As shown, the system includes a drying bed 1, on which a feed hopper 2 and a discharge hopper 3 are fixedly connected. The drying bed 1 has one cold air inlet and two hot air inlets. The drying bed 1 is connected to both the feed hopper 2 and the discharge hopper 3. A servo motor 4 is fixedly connected to the outer wall of the discharge hopper 3. A star-shaped propeller 5 is rotatably connected inside the discharge hopper 3. A bevel gear set 61 is provided between the output shaft of the servo motor 4 and one end of the star-shaped propeller 5. The bevel gear set 61 is located outside the discharge hopper 3. 5. A rotating disk 62 is fixedly connected to the other end. The rotating disk 62 is located outside the discharge hopper 3. A protruding post 7 is fixedly connected to the rotating disk 62. Two fixing blocks 8 are fixedly connected to the outer wall of the discharge hopper 3. The two fixing blocks 8 are symmetrically arranged. A slide frame 9 is slidably connected between the two fixing blocks 8. A screen frame 10 is slidably connected inside the discharge hopper 3. The screen frame 10 is fixedly connected to the slide frame 9. A scraper frame 11 is fixedly connected inside the discharge hopper 3. The scraper frame 11 passes through the screen frame 10.

[0018] The bevel gear set 61 consists of a driving bevel gear and a transmission bevel gear. The driving bevel gear is fixedly connected to the output shaft of the servo motor 4, and the transmission bevel gear is fixedly connected to one end of the star propeller 5. The driving bevel gear meshes with the transmission bevel gear.

[0019] The carriage 9 has a straight groove, and the protruding post 7 is located in the straight groove on the carriage 9.

[0020] The sieve frame 10 is located above the star-shaped paddle 5.

[0021] The top of the scraper frame 11 is in contact with the sieve frame 10.

[0022] First, wet salt particles are fed into the drying bed 1 through the feed hopper 2. After being dried in the drying bed 1, the wet salt particles enter the discharge hopper 3, where they fall onto the screen frame 10. Simultaneously, the servo motor 4 starts, driving the star-shaped propeller 5 to rotate via the bevel gear set 61. The rotation of the star-shaped propeller 5 drives the rotating disk 62 to rotate, which in turn drives the convex column 7 to rotate. The rotation of the convex column 7 causes the slide 9 to move horizontally back and forth, which in turn causes the screen frame 10 to move horizontally back and forth. This horizontal back and forth movement of the screen frame 10 then refracts the dry salt particles falling onto it. During the sieving process, as the screen frame 10 moves horizontally back and forth, the scraper frame 11 continuously scrapes away the coarse salt particles clogging the screen frame 10, keeping the screen frame 10 unobstructed and improving sieving efficiency. The sieved dry salt particles fall into the lower part of the discharge hopper 3. The rotating star-shaped paddle 5 evenly discharges the dry salt particles from the lower part of the discharge hopper 3. In this way, the star-shaped paddle 5 can stabilize the salt output of the drying bed 1, ensuring that the salt is discharged evenly from the discharge hopper 3 of the drying bed 1. At the same time, the larger salt particles are sieved out by the screen frame 10, preventing the salt particles from clogging and jamming the star-shaped paddle 5.

Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
