Description

Technical Field

[0001] This utility model relates to the field of disc dryer technology, and in particular to a high-efficiency disc dryer. Background Technology

[0002] A disc dryer is a type of indirect heating continuous drying equipment. Its core consists of multiple layers of hollow heating discs through which a heat source is introduced to heat the material. Specially arranged scrapers guide the material in a zigzag flow between the upper and lower discs, extending the residence time and achieving uniform and efficient drying. It is suitable for powdery, granular, and filter cake materials.

[0003] The angle of the scraper in a disc dryer is crucial. Different materials have different drying characteristics, requiring adjustment of the scraper angle to optimize the process. For materials prone to overheating or coking, the scraper angle should be reduced to allow them to pass quickly across the disc, shortening their residence time. Conversely, for materials requiring deep drying, the angle should be increased to extend their residence path and time on each disc, achieving thorough drying. Therefore, targeted adjustment of the scraper angle is a key operation for improving drying efficiency and product quality.

[0004] However, the existing scraper angle adjustment process of disc dryers is extremely cumbersome and inefficient. It not only requires a complete shutdown and cooling, but also requires operators to enter the equipment and adjust each scraper distributed on the multi-layer disc surface. This consumes a lot of time and manpower, and causes production interruption, which seriously restricts the operating efficiency of the entire production line. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0006] Therefore, one objective of this utility model is to propose a high-efficiency disc dryer, which, by setting an angle adjustment mechanism, enables the synchronous adjustment of the angle of all scrapers during the production process, thereby greatly improving the production efficiency of the equipment.

[0007] To achieve the above objectives, the first aspect of this utility model proposes a high-efficiency disc dryer, comprising: a tank body, a feeding assembly, a drying assembly, and a pushing assembly. The tank body includes a fixed base, a discharge pipe, and a glass cover. The discharge pipe is fixedly connected to the front side of the fixed base, and the glass cover is fixedly connected to the top of the fixed base. The feeding assembly is disposed at the top of the glass cover, and the drying assembly is disposed inside the glass cover. The pushing assembly includes a drive unit, a rotating tube, multiple support tubes, multiple scrapers, and an angle adjustment mechanism. The drive unit is mounted at the top of the glass cover. The rotating tube is rotatably connected to the fixed base and the inside of the glass cover, and is connected to the drive unit. The multiple support tubes are respectively fixedly connected to the outside of the rotating tube, and the multiple scrapers are respectively rotatably connected to the bottom end of the corresponding support tube. The angle adjustment mechanism is disposed inside the rotating tube and the support tubes, and is connected to the multiple scrapers.

[0008] In addition, the high-efficiency disc dryer proposed above according to this utility model may also have the following additional technical features: Specifically, the drying assembly includes multiple flow pipes, two connecting rings, multiple drying trays, and a discharge ring. The multiple flow pipes are vertically fixedly connected to the inside of the tank. The two connecting rings are fixedly connected to the top and bottom of the corresponding flow pipes. The multiple drying trays are fixedly connected between the corresponding flow pipes. The discharge ring is fixedly connected to the inside of the fixed base, and one end of the discharge ring is connected to the discharge pipe.

[0009] Specifically, the angle adjustment mechanism includes multiple first bevel gears, multiple first rotating shafts, multiple support frames, multiple second rotating shafts, and a first motor. The multiple first bevel gears are respectively fixedly connected to the top of the scraper; the multiple first rotating shafts are respectively rotatably connected to the inner side of the corresponding support tube; multiple second bevel gears are fixedly connected to the outer side of the first rotating shafts, and the first bevel gears mesh with the second bevel gears; the multiple support frames are respectively fixedly connected to the inner side of the rotating tube. Multiple second rotating shafts are vertically rotatably connected to the inner side of the corresponding support frame, and a fourth bevel gear is fixedly connected to both ends of the second rotating shaft. A third bevel gear is fixedly connected to one end of the first rotating shaft, and the third bevel gear meshes with the fourth bevel gear. The first motor is fixedly installed at the bottom end of the inner side of the rotating tube, and a fifth bevel gear is fixedly connected to the top end of the first motor drive shaft, and the fifth bevel gear meshes with the corresponding third bevel gear.

[0010] Compared with the prior art, the present invention has the following beneficial effects: The high-efficiency disc dryer has an angle adjustment mechanism, which is driven by a motor and works in conjunction with a bevel gear transmission system to synchronously adjust the tilt angle of all scrapers, solving the problem that the existing disc dryer must be stopped to cool down before manual adjustment can be made, thus greatly improving production efficiency.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The high-efficiency disc dryer of this utility model is described below with reference to the accompanying drawings.

[0020] like Figures 1-5 As shown in the figure, a high-efficiency disc dryer according to an embodiment of the present invention includes: a tank 1, a feeding assembly 2, a drying assembly 3, and a pushing assembly 4.

[0021] Tank 1 includes a fixed base 11, a discharge pipe 12, and a glass cover 13. The discharge pipe 12 is fixedly connected to the front side of the fixed base 11, and the glass cover 13 is fixedly connected to the top of the fixed base 11. It should be noted that the glass cover 13 in this embodiment is made of high temperature resistant material, which can withstand the high temperature generated by the drying component 3 during operation, and a metal cover is fixedly connected to the top of the glass cover 13 to facilitate the connection of the feeding component 2.

[0022] The feeding component 2 is located at the top of the glass cover 13.

[0023] It should be noted that the feeding assembly 2 in this embodiment includes a feeding funnel 21, a spiral feeding shaft 22, and a second motor 23. The feeding funnel 21 is fixedly connected to the bottom of the metal cover of the glass cover 13, the spiral feeding shaft 22 is rotatably connected to the inside of the feeding funnel 21, and the second motor 23 is fixedly installed on the top of the metal cover, and the drive shaft of the second motor 23 is fixedly connected to the spiral feeding shaft 22.

[0024] The drying assembly 3 is located inside the glass cover 13. The drying assembly 3 includes multiple flow pipes 31, two connecting rings 32, multiple drying trays 33, and a discharge ring 34.

[0025] Among them, multiple flow pipes 31 are vertically fixedly connected to the inside of the tank 1, two connecting rings 32 are fixedly connected to the top and bottom of the corresponding flow pipes 31, multiple drying trays 33 are fixedly connected between the corresponding flow pipes 31, and a discharge ring 34 is fixedly connected to the inside of the fixed base 11, with one end of the discharge ring 34 connected to the discharge pipe 12.

[0026] It should be noted that the drying tray 33 in this embodiment is divided into an outer push tray and an inner push tray. The outer push tray and the inner push tray are arranged vertically at intervals. The outer diameter of the outer push tray is smaller than the outer diameter of the inner push tray, and the inner diameter of the outer push tray is smaller than the inner diameter of the inner push tray. When the scraper 43 pushes the material on the outer push tray, it pushes the powder from the outer edge of the outer push tray into the inner push tray. When the scraper 43 pushes the material on the inner push tray, it pushes the powder from the inner edge of the inner push tray into the outer push tray, thereby increasing the movement path of the powder.

[0027] It should be noted that, in this embodiment, two of the multiple flow pipes 31 are connected to the external heating system and control valve respectively. The heating system sends high-temperature steam into the drying tray 33 through the flow pipes 31 for heating, and the control valve controls the steam discharge, so that the drying tray 33 maintains high pressure and improves heating efficiency.

[0028] The pushing component 4 includes a drive unit, a rotating tube 41, multiple support tubes 42, multiple scrapers 43, and an angle adjustment mechanism 44.

[0029] The drive unit is installed at the top of the glass cover 13. The rotating tube 41 is rotatably connected to the fixed base 11 and the inner side of the glass cover 13, and the rotating tube 41 is connected to the drive unit. Multiple support tubes 42 are fixedly connected to the outer side of the rotating tube 41, and multiple scrapers 43 are rotatably connected to the bottom end of the corresponding support tube 42. An angle adjustment component is set inside the rotating tube 41 and the support tube 42, and the angle adjustment component is connected to the multiple scrapers 43.

[0030] It should be noted that the driving unit in this embodiment is a drive motor, and the drive motor is installed on the top of the metal cover. The drive shaft of the drive motor is fixedly connected to the top of the rotating tube 41, and the rotating tube 41 can be driven to rotate by the drive motor.

[0031] Specifically, when technicians need to dry powder materials, they can use this high-efficiency disc dryer.

[0032] First, employees need to turn on the external heating system to heat up the drying tray 33. Employees can use a thermometer to monitor the internal temperature of the tank 1 at all times. After the temperature rises to the required temperature, they stop heating and maintain that temperature.

[0033] Next, the employee introduces the powder into the feeding hopper 21 and starts the second motor 23, which drives the spiral feeding shaft 22 to rotate inside the feeding hopper 21, spreading the powder evenly on the drying tray 33 below.

[0034] Then, the worker starts the drive motor, which drives the rotating tube 41 to rotate. The powder is scraped onto the drying tray 33 by the scraper 43 at the bottom of the support tube 42, so that the powder is conveyed from top to bottom on each drying tray 33.

[0035] Finally, the powder falls into the discharge ring 34 and is discharged from the discharge pipe 12. As the powder is continuously poured into the feed funnel 21, the powder is continuously dried.

[0036] In one embodiment of this utility model, such as Figure 4 and Figure 5 As shown, the angle adjustment mechanism 44 includes multiple first bevel gears 441, multiple first rotating shafts 442, multiple support frames 445, multiple second rotating shafts 446, and a first motor 448.

[0037] In this system, multiple first bevel gears 441 are fixedly connected to the top of scraper 43, multiple first rotating shafts 442 are rotatably connected to the inner side of corresponding support tubes 42, multiple second bevel gears 443 are fixedly connected to the outer side of the first rotating shafts 442, and the first bevel gears 441 mesh with the second bevel gears 443, multiple support frames 445 are fixedly connected to the inner side of rotating tubes 41, multiple second rotating shafts 446 are vertically rotatably connected to the inner side of corresponding support frames 445, and the two ends of the second rotating shafts 446 are fixedly connected to fourth bevel gears 447, one end of the first rotating shafts 442 is fixedly connected to a third bevel gear 444, and the third bevel gear 444 meshes with the fourth bevel gear 447, a first motor 448 is fixedly installed at the bottom of the inner side of rotating tubes 41, and the top of the drive shaft of the first motor 448 is fixedly connected to a fifth bevel gear 449, which meshes with the corresponding third bevel gear 444.

[0038] It should be noted that the first bevel gear 441, the second bevel gear 443, the third bevel gear 444, and the fourth bevel gear 447 in this embodiment have the same specifications. During rotational transmission, they improve the accuracy of adjusting the scraper 43. Furthermore, the first bevel gear 441 is equipped with a rotation angle sensor, which can detect the rotation angle of the scraper 43. The rotation angle sensor has signal transmission with a remote receiver, and the data from the rotation angle sensor can be read by the remote receiver to determine the rotation angle of the scraper.

[0039] Specifically, when it is necessary to adjust the angle of the scraper 43, the employee only needs to start the first motor 448. The drive shaft of the first motor 448 can synchronously drive the multiple third bevel gears 444 meshing with it to rotate through the fixedly connected fifth bevel gear, thereby causing the first rotating shaft 442 to rotate. The first rotating shaft 442 drives the corresponding first bevel gear 441 to rotate through the multiple external second bevel gears 443, thereby allowing the scraper 43 to adjust its angle.

[0040] Since the connected scrapers 43 are set at opposite angles, when the third bevel gear 444 rotates, it can drive the fourth bevel gear 447 to rotate, which in turn causes the second rotating shaft 446 to rotate. The second rotating shaft 446 is equipped with the fourth bevel gear 447 at both ends, so that the rotation directions of the first rotating shaft 442 of the adjacent upper and lower layers are opposite, which in turn causes the scrapers 43 of the two adjacent upper and lower layers to rotate in different directions, achieving precise adjustment.

[0041] In summary, the high-efficiency disc dryer of this invention can simultaneously adjust the angle of all scrapers 43. Through the gear layout, it can automatically achieve reverse adjustment of the angle of adjacent scrapers 43, solving the problem that traditional equipment must be stopped and manually adjusted one by one, thus significantly improving drying efficiency.
