Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of industrial salt preparation equipment, specifically a disc dryer for industrial salt preparation. Background Technology
[0002] As an important basic chemical raw material, the drying process in the preparation of industrial salt plays a decisive role in product quality and production efficiency. Disc dryers are widely used in industrial salt preparation due to their advantages such as high thermal efficiency and small footprint. However, existing disc dryers still have many problems in practical applications.
[0003] In the prior art, traditional disc dryers have limited capacity to handle unqualified particles or impurities generated during the drying process. For example, industrial salt is prone to sticking and clumping when it is damp, resulting in the dried industrial salt often containing lumps, sticking particles and other impurities. These impurities cannot be effectively separated, which reduces the quality of the product. Therefore, this utility model proposes a disc dryer for industrial salt preparation to solve the above problems. Utility Model Content

By optimizing the structure of the drying disc and incorporating efficient scraping and impact mechanisms, this invention solves problems such as low drying efficiency, uneven material handling, and difficulty in separating impurities found in existing drying equipment. This improves the drying quality and production efficiency of industrial salt, reduces equipment maintenance costs, and enhances the applicability and reliability of the equipment.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: It includes a tank body, inside which a first drying tray and a second drying tray are arranged from top to bottom. Heat-conducting strips are fixedly connected to the side walls at both ends of the first and second drying trays. Multiple heat-conducting strips pass through and are fixedly connected to the side walls of the tank body. A through hole is opened at the center of the first drying tray. The diameters of both the first and second drying trays are smaller than the inner diameter of the tank body. A scraping mechanism for scraping material off the first and second drying trays is provided inside the tank body. A filter screen is fixedly connected to the inner wall of the tank body below the second drying tray. An impact mechanism for impacting the filter screen is provided at the lower end of the second drying tray. The impact mechanism includes two symmetrically arranged telescopic rods fixedly connected to the lower end of the second drying tray. A moving plate is fixedly connected to the telescopic ends of the two telescopic rods. Two symmetrically arranged impact rods are fixedly connected to the lower end of the moving plate. An impact head, made of rubber, is fixedly connected to the lower end of each of the two impact rods.
[0008] Preferably, the scraping mechanism includes a rotating rod rotatably connected to the top of the tank body, and four first stirring paddles distributed circumferentially at equal intervals are fixedly sleeved on the rotating rod. The lower ends of the four first stirring paddles are in contact with the upper end surface of the first drying tray. Four second stirring paddles distributed circumferentially at equal intervals are fixedly sleeved on the rotating rod.

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a disc dryer for industrial salt preparation, which has the following beneficial effects:
[0015] 1. Through the setting of the impact mechanism, driven by the reciprocating screw, the filter screen can be periodically impacted. When industrial salt material passes through the filter screen, impurities are intercepted. The impact mechanism can cause the filter screen to vibrate by continuously impacting the filter screen. The vibration can facilitate the rapid passage of dried salt through the filter screen. At the same time, the agglomerated material can be shaken apart under the action of shaking, which can greatly improve the product quality.
[0016] 2. By setting up a first drying tray and a second drying tray, and fixing heat-conducting strips to their side walls, heat energy can be utilized more fully, allowing heat to be evenly transferred to all parts of the drying tray. This effectively avoids problems such as localized overheating or insufficient drying of the material. The design of the first and second stirring paddles in the scraping mechanism, driven by the rotating rod, can continuously stir and scrape the material on the first and second drying trays, causing the material to constantly change position, increasing the contact area with hot air, accelerating moisture evaporation, thereby significantly improving drying efficiency, ensuring uniform drying of industrial salt, and improving product quality and purity. The design of the first stirring paddle is as follows: Figure 4 As shown, when rotated clockwise, the first stirring paddle forms an inclined angle with the material on the first drying tray. During rotation, the material on the first drying tray is gradually scraped off through the through-hole. The design of the second stirring paddle is as follows... Figure 5 As shown, its inclined surface is designed opposite to that of the first stirring paddle. When rotated clockwise, it can make the second stirring paddle form an inclined angle with the material on the second drying tray, scraping the material on the second drying tray from the edge of the second drying tray.

[0026] This utility model provides a technical solution:
[0027] Please see Figure 1-6A disc dryer for industrial salt preparation includes a tank body 1, inside which a first drying disc 9 and a second drying disc 10 are arranged from top to bottom. Heat-conducting strips 8 are fixedly connected to the side walls at both ends of the first drying disc 9 and the second drying disc 10. Multiple heat-conducting strips 8 pass through and are fixedly connected to the side walls of the tank body 1. The heat-conducting strips 8 are used to transfer heat from an external heat source to the drying discs, providing thermal energy for the drying of the industrial salt material. A through hole 12 is provided at the center of the first drying disc 9 to allow the material dried on the first drying disc 9 to fall onto the second drying disc 10 for further drying. The diameters of both the first drying disc 9 and the second drying disc 10 are smaller than the inner diameter of the tank body 1, ensuring that the material can be fully distributed on the drying discs and fall smoothly.
[0028] Specifically, the tank body 1 is equipped with a scraping mechanism inside for scraping off the material on the first drying tray 9 and the second drying tray 10. The scraping mechanism includes a rotating rod 14 rotatably connected to the top of the tank body 1. Four first stirring paddles 13, evenly spaced circumferentially, are fixedly sleeved on the rotating rod 14. The lower ends of the four first stirring paddles 13 contact the upper surface of the first drying tray 9, and are used to stir and scrape off the material on the first drying tray 9 during rotation. Four second stirring paddles 15, also evenly spaced circumferentially, are also fixedly sleeved on the rotating rod 14. The lower ends of the four second stirring paddles 15 contact the upper surface of the second drying tray 10, and are used to stir and scrape off the material on the second drying tray 10. A motor 3 is fixedly connected to the upper end of the tank body 1. The output shaft of the motor 3 is fixedly connected to the upper end of the rotating rod 14, providing power to the scraping mechanism. The design of the first stirring paddles 13 is as follows... Figure 4 As shown, when rotated clockwise, the first stirring paddle 13 forms an inclined angle with the material on the first drying tray 9. During rotation, the material on the first drying tray 9 is gradually scraped off through the through hole 12. The design of the second stirring paddle 15 is as follows... Figure 5 As shown, its inclined surface is designed opposite to that of the first stirring paddle 13. When rotated clockwise, it can make the second stirring paddle 15 form an inclined angle with the material on the second drying tray 10, scraping the material on the second drying tray 10 from the edge.
[0029] Specifically, a filter screen 7 is fixedly connected to the inner wall of the tank 1 located below the second drying tray 10 to filter impurities in the dried industrial salt material. An impact mechanism for impacting the filter screen 7 is provided at the lower end of the second drying tray 10. The impact mechanism includes two symmetrically arranged telescopic rods 16 fixedly connected to the lower end of the second drying tray 10. The telescopic ends of the two telescopic rods 16 are fixedly connected to a moving plate 19. Two symmetrically arranged impact rods 17 are fixedly connected to the lower end of the moving plate 19. An impact head 18 is fixedly connected to the lower end of each of the two impact rods 17. The impact head 18 is made of rubber. A reciprocating screw 20 is fixedly connected to the lower end of the rotating rod 14. The reciprocating screw 20 passes through the moving plate 19 and cooperates with it. When the rotating rod 14 rotates, it drives the reciprocating screw 20 to rotate, so that the moving plate 19 reciprocates under the guidance of the telescopic rods 16, realizing the impact of the impact head 18 on the filter screen 7. The clumps of material can be shaken apart under the action of shaking, which can greatly improve the product quality.
[0030] Specifically, a hopper 5 is provided at the lower end of the tank body 1. The hopper 5 is funnel-shaped and has a discharge port 6 at its lower end for collecting and discharging dried and qualified industrial salt material. A feed port 2 is provided at the upper end of the tank body 1 for feeding in industrial salt material to be dried. Four support legs 4 are fixedly connected to the side wall of the hopper 5 and are arranged at equal intervals in a circumferential direction to support the entire device.
[0031] In practical use, the working principle of this utility model is as follows:
[0032] Industrial salt material enters through the feed inlet 2 at the top of tank 1 and first falls onto the first drying tray 9. The heat-conducting strips 8 on the side wall of tank 1 transfer heat to the first drying tray 9 and the second drying tray 10, providing a heat source for the drying process. After the motor 3 starts, its output shaft drives the rotating rod 14 to rotate. The four first stirring paddles 13 fixedly sleeved on the rotating rod 14 rotate accordingly. The lower ends of the first stirring paddles 13 contact the upper surface of the first drying tray 9, stirring and scraping the industrial salt material on the first drying tray 9 during rotation. This continuous movement of the material increases the contact area with hot air. Finally, the material on the first drying tray 9 is gradually scraped out through the through-hole 12 under the push of the first stirring paddles 13, accelerating moisture evaporation and achieving initial drying. After drying on the first drying tray 9, the material falls onto the second drying tray 10 through the through-hole 12 at the center of the first drying tray 9. The four second stirring paddles 15 on the rotating rod 14 continue to stir and scrape the material on the second drying tray 10, further drying the material. The rotation of the second stirring paddles 15 drives the second drying tray... The material on the second drying tray 10 is discharged from its edge onto the filter screen 7. During the falling process of the industrial salt material after being dried by the second drying tray 10, unqualified particles, clumps, and impurities are intercepted by the filter screen 7. At the same time, the lower end of the rotating rod 14 is fixedly connected to the reciprocating screw 20, which passes through the moving plate 19 and cooperates with it. When the rotating rod 14 rotates, it drives the reciprocating screw 20 to rotate, causing the moving plate 19 to reciprocate under the guidance of the telescopic rod 16. The impact rod 17 and impact head 18 fixedly connected to the lower end of the moving plate 19 move together with the moving plate 19, periodically impacting the filter screen 7. Since the impact head 18 is made of rubber, it can avoid damaging the filter screen 7 while ensuring the impact force. Through continuous impact, the vibration discharged from the hopper 5 and the discharge port 6 at the lower end of the tank 1 can facilitate the rapid passage of the dried salt material through the filter screen 7. At the same time, the clumps of material can be shaken apart by the vibration, which can greatly improve the product quality.
[0033] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
