Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to an anti-stick single-drum dryer. Background Technology

[0002] Single-drum dryers are mainly used in mineral processing, building materials, metallurgy, and chemical industries to dry materials with a certain moisture content or particle size. Rotary dryers are highly adaptable to materials and can dry various materials. Moreover, the equipment is simple and reliable to operate, so it is widely used. A single-drum dryer consists of a cylindrical drum as the main body of the dryer. When using a single-drum dryer, some materials (such as slurry materials and wet coal) have strong adhesive properties and are prone to adhering to the inner wall of the drum at high temperatures. When the material adheres to the inner wall of the drum, it will reduce the efficiency of heat transfer, resulting in a decrease in drying effect. The adhered material will form a heat insulation layer, which will hinder the conduction of heat and prolong the drying time.

[0003] When drying materials, the amount of material added each time varies. During the drying process, the heat needs to be evenly distributed in the drying drum. Therefore, when the amount of material is small, the heat is relatively dispersed, resulting in greater energy consumption. It is difficult to concentrate the heat according to the amount of material, thus generating more energy waste.

[0004] Therefore, a non-stick single-drum dryer is proposed. Utility Model Content

[0024] like Figure 1-4As shown, an anti-stick single-drum dryer includes a base plate 1, two support plates 2 at the top of the base plate 1, a sealed box 3 between the two support plates 2, an exhaust filter 301 on the exhaust port of the sealed box 3, a collection box 4 slidably disposed at the bottom of the sealed box 3, a first drying drum 7 and a second drying drum 701 rotatably disposed and fixedly connected to each other inside the sealed box 3, a discharge hopper 705 disposed on the second drying drum 701, a second solenoid valve 706 disposed on the discharge hopper 705, a feed hopper 707 extending into the first drying drum 7 disposed on the support plate 2, a limiting member 6 for limiting the drying distance disposed on the support plate 2, the limiting member 6 including a sealing plate 602 slidably disposed inside the second drying drum 701, and a blowing drying member 5 disposed on the sealed box 3 for drying the material inside the second drying drum 701, the blowing drying member 5 including a hot air blower 501, a connecting plate 502 and multiple air blowing plates 503; specifically The exhaust port can be equipped with appropriate air purification or condensation equipment to condense and purify the steam discharged during drying, thus preventing pollution of the factory environment. Further details are omitted here. To avoid interference from the exhaust, the air inlet of the hot air blower 501 can be positioned far from the exhaust port. The air blowing plate 503 is spaced a certain distance from the second drying cylinder 701. When the second drying cylinder 701 rotates, it drives the discharge hopper 705 to rotate, thus not interfering with its normal rotation. The second solenoid valve 706 is powered by a battery, so there is no problem of wire tangling when it rotates. Before drying the material, a weighing machine can be used to detect the material weight. Based on the detected material weight, the drying distance is adjusted by the limiting component 6, and the drying range of the blowing drying component 5 is also adjusted. This allows for adjustment of the drying distance according to the material weight, thus saving energy.

[0025] like Figure 4 As shown, the output end of the hot air blower 501 extends into the interior of the connecting plate 502. The air blowing plate 503 is located inside the sealed box 3, directly above the second drying cylinder 701. Each air blowing plate 503 is provided with a connecting branch pipe 504 that is connected to the connecting plate 502. A first solenoid valve 505 is provided on the connecting branch pipe 504. Specifically, when the corresponding first solenoid valve 505 is opened, the corresponding air blowing plate 503 can blow air, thus allowing the air blowing range to be adjusted.

[0026] like Figure 4 As shown, the lower surface of the air blowing plate 503 is arc-shaped, and multiple evenly arranged air blowing holes are opened on its lower surface; specifically, the air blowing plate 503 wraps around the second drying cylinder 701 to dry it, increasing the air blowing area and thus accelerating the drying of the material.

[0027] like Figure 3 As shown, an electric telescopic rod 601 is provided on the support plate 2. The sealing plate 602 is connected to the telescopic end of the electric telescopic rod 601. A telescopic scraper 603 is provided on one side of the sealing plate 602. One end of the telescopic scraper 603 is connected to a fixing plate 604. The fixing plate 604 is fixedly connected to one side of the sealing box 3. The bottom of the telescopic scraper 603 is in contact with the inner side of the second drying cylinder 701. Specifically, the extension and retraction of the electric telescopic rod 601 can drive the sealing plate 602 to slide inside the second drying cylinder 701, thus limiting the drying distance of the material. The telescopic scraper 603 can scrape the material inside the second drying cylinder 701, thus removing the material stuck inside the second drying cylinder 701 and playing a role in preventing sticking. Since one side of the telescopic scraper 603 is connected to the sealing box 3 through the fixing plate 604, one side of the telescopic scraper 603 is fixed. Therefore, when the sealing plate 602 moves, the telescopic scraper 603 can move and retract accordingly.

[0028] like Figure 2 As shown, the second drying cylinder 701 has multiple evenly arranged slots, the outer surface of the first drying cylinder 7 is fitted with a toothed ring 702, and a motor 703 is installed on one side of the inside of the sealed box 3. The main shaft end of the motor 703 is connected to a gear 704, and the gear 704 and the toothed ring 702 are meshed together. Specifically, the slots on the second drying cylinder 701 facilitate the entry of hot air, and small particles can also be collected inside the collection box 4. The inside of the first drying cylinder 7 is conical, which allows the material to slide into the second drying cylinder 701, avoiding the accumulation of material inside the first drying cylinder 7 and making it difficult to discharge.

[0029] like Figure 1 As shown, the collection box 4 is located directly below the first drying cylinder 7 and the second drying cylinder 701, and the top of the collection box 4 is designed to be open.

[0030] In summary: The material to be dried is first weighed, and the length of the electric telescopic rod 601 is adjusted according to the amount of material. This allows the sealing plate 602 to be pushed to the corresponding position, thereby adjusting the drying distance. Simultaneously, the drying range can be adjusted by opening and closing the corresponding first solenoid valve 505. Therefore, when the amount of material is small, the drying distance can be shortened, allowing heat to be concentrated on the surface of the material, thus saving energy. During the drying process, the motor 703 drives the gear 704 to rotate. The gear 704 meshes with the gear ring 702, which in turn drives... The first drying cylinder 7 and the second drying cylinder 701 rotate, thus causing the material to roll. Under the blowing action of the hot air blower 501, the material can be dried. During drying, the telescopic scraper 603 can scrape the inner wall of the rotating second drying cylinder 701, thus removing the material adhering to the inside of the second drying cylinder 701 and playing a role in preventing sticking. Subsequently, the humidity of the gas discharged from the exhaust port can be detected. When the humidity reaches the set value, the drying process is stopped and the material is discharged. The drying time can be controlled by various methods, which will not be elaborated on here.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
