Description

Technical Field

[0001] This utility model relates to the field of chemical product manufacturing technology, and in particular to a drying device for chemical product manufacturing. Background Technology

[0002] Drying equipment for chemical product manufacturing is a device that removes moisture or solvents from materials through physical means. Its core is to use heat conduction, heat convection, heat radiation and other methods to bring the material to a specified moisture content. Common equipment includes chamber dryers, fluidized bed dryers, spray dryers and so on. It is widely used in chemical, pharmaceutical, food and other fields and can meet the drying needs of different materials (such as granules, solutions and pastes) to ensure product quality and production efficiency.

[0003] Traditional granular chemical drying equipment mostly relies on direct contact between heat sources (such as steam or hot air) and materials to achieve drying. However, this has significant drawbacks for materials with high moisture content: a large amount of moisture in the material needs to be gradually evaporated, and the heat source can only slowly conduct heat from the surface of the material to the interior, resulting in slow migration of moisture in the inner layer. To accelerate moisture evaporation, the temperature of the heat source needs to be continuously increased or the drying time extended, leading to a significant increase in energy consumption. To solve the above problems, we have proposed this drying equipment for chemical product production. Utility Model Content

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figs. 1-3As shown, a drying device for chemical product production includes a drying chamber 1, a hot air blower 3, a dehydration chamber 8, and a top cover 17. The drying chamber 1 contains a rotating drum 2, an air outlet box 4, and multiple support plates 5. The drying chamber 1 is equipped with a discharge pipe 6 and an air outlet pipe 7 that communicate with its interior. The support plates 5 are rotatably connected to the rotating drum 2. The rotating drum 2 has multiple discharge ports on its side wall. The drying chamber 1 has a drive assembly for the rotating drum 2 on its side wall. The air outlet box 4 has multiple air outlets at its upper end (not shown in the figure). The hot air blower 3 is connected to the air outlet box 4 through a hot air pipe. Valves are provided on the discharge pipe 6, the connecting pipe 11, and the drain pipe 10.

[0021] The dehydration chamber 8 is equipped with a dehydration mechanism for removing moisture from the product. The dehydration mechanism includes a sieve cylinder 9 rotatably connected to the side wall of the upper cover 17. A first motor 16 is fixedly connected to the lower end of the dehydration chamber 8. A rotating shaft 15 is fixedly connected to the output shaft of the first motor 16. Gears and gear rings are respectively provided on the side wall of the rotating shaft 15 and the sieve cylinder 9. A drain pipe 10 and a connecting pipe 11 are provided on the dehydration chamber 8. A vertical pipe 14 is connected to the lower end of the sieve cylinder 9. The vertical pipe 14 and the connecting pipe 11 are rotatably connected. A material guide shell 12 is provided on the drying chamber 1. The material guide shell 12 is rotatably connected to the rotating drum 2.

[0022] The drying oven 1 has a stirring mechanism on its side wall for stirring products. The stirring mechanism includes a second motor 19 fixedly connected to the side wall of the drying oven 1. The output shaft of the second motor 19 is fixedly connected to a rotating shaft 20. Multiple lifting plates 21 are fixedly connected to the side wall of the rotating shaft 20.

[0023] In this invention, two guide plates 18 are fixedly connected to the bottom of the drying chamber 1. The two guide plates 18 are symmetrically distributed opposite the central axis of the discharge pipe 6, which can speed up the discharge of materials from the discharge pipe 6.

[0024] In this invention, the bottom of the dehydration tank 8 is provided with an inclined surface to facilitate the rapid discharge of water, and the inner wall of the sieve cylinder 9 is provided with an inclined surface to facilitate the discharge of the product.

[0025] In this utility model, observation openings are provided on both sides of the dehydration tank 8, and observation windows 13 are provided in the observation openings to facilitate observation of the dehydration situation inside the dehydration tank 8.

[0026] In this utility model, the upper end of the sieve cylinder 9 is connected to a feeding hopper, which can reduce the product falling when it is poured in. The air outlet pipe 7 is equipped with a fan 22. The side wall of the drying chamber 1 is equipped with a temperature sensor (not shown in the figure). The side wall of the drying chamber 1 is equipped with a control box. The temperature sensor monitors the temperature inside the drying chamber 1 in real time. The control box automatically adjusts the air volume of the hot air blower 3 and the rotation speed of the rotating cylinder 2 according to the set parameters to ensure drying efficiency and product quality.

[0027] During use, the material enters the dewatering tank 8 through the feed hopper at the top of the screen cylinder 9. The first motor 16 drives the rotating shaft 15, which drives the screen cylinder 9 to rotate at a high speed of 500~1000 r / min through the gear ring transmission. Under the action of centrifugal force, the water in the material is thrown out through the mesh of the screen cylinder 9 and discharged through the drain pipe 10 along the bottom slope of the dewatering tank 8. The dewatered material slides down the inner wall slope of the screen cylinder 9 to the vertical pipe 14, and then enters the guide shell 12 through the connecting pipe 11 to complete the pre-dewatering process.

[0028] The material guide shell 12 feeds the pre-dehydrated material into the rotating drum 2. The hot air blower 3 delivers hot air (temperature adjustable from 60 to 150°C) to the air outlet box 4. The hot air enters the rotating drum 2 through the air outlet. The second motor 19 drives the lifting plate 21 to rotate, lifting and scattering the material to form a uniform material curtain that fully contacts the hot air. During the drying process, the moisture in the material evaporates into water vapor, which is discharged through the blower 22 of the air outlet pipe 7. The dried material falls to the bottom of the drying chamber 1 through the discharge port on the side wall of the rotating drum 2 and is guided by the material guide plate 18 to be discharged from the discharge pipe 6.
