Description

Technical Field

[0001] This utility model belongs to the field of drying technology, specifically a three-in-one dryer. Background Technology

[0002] The three-in-one dryer is a device that integrates mixing, reaction, and drying functions, and is widely used in many industries such as chemical, pharmaceutical, and food. However, existing three-in-one dryers have the problem of being difficult to clean during use.

[0003] Due to the complex internal structure of the three-in-one dryer, after the mixing, reaction, and drying of materials, material tends to remain in various corners inside the equipment, such as the connection between the agitator and the drying cylinder, and in the material conveying channels. This residue not only affects the quality of subsequent material processing but can also breed bacteria, produce unpleasant odors, and even cause equipment malfunctions. Currently, cleaning the three-in-one dryer mostly requires manual entry, which is not only inefficient but also poses certain safety hazards. Furthermore, manual cleaning is insufficient to thoroughly clean every corner inside the equipment.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a three-in-one dryer, including a drying cylinder body 1, which consists of a tank and a cover. The cover is detachably installed on top of the tank using a threaded design, facilitating inspection and cleaning of the interior of the drying cylinder body. A support frame 2 is installed on the bottom surface of the drying cylinder body 1 to support the entire dryer and ensure its stability. A feed pipe 3 is installed at the top of the drying cylinder body 1 where the feed inlet is located, and a discharge pipe 4 is installed at the bottom where the discharge outlet is located. Both the feed pipe 3 and the discharge pipe 4 are equipped with electromagnetic control valves. By controlling the opening and closing of the electromagnetic control valves, automatic feeding and discharging of materials can be achieved. The drying cylinder body 1 is equipped with a stirring paddle 5, which is connected to the output shaft of a drive motor 6. The drive motor 6 is fixedly installed at the top of the drying cylinder body 1. The stirring paddle 5 consists of two helical blades of different sizes, and the two helical blades are in opposite directions. This unique structural design allows the stirring paddle to generate stirring forces in different directions on the material when rotating, thereby achieving full mixing and tumbling of the material, which greatly improves the uniformity and efficiency of drying. The drying cylinder body 1 is equipped with a detachable wear-resistant coated tube 7. Two locking blocks 9 are symmetrically installed on the outer surface of the wear-resistant coated tube 7. The inner wall of the drying cylinder body 1 has a locking groove 10 that matches the locking blocks 9. The wear-resistant coated tube 7 slides on the inner wall surface of the drying cylinder body 1 via the locking blocks 9 and the locking groove 10, and the wear-resistant coated tube 7 is compatible with the inner wall surface of the drying cylinder body 1. This detachable wear-resistant coated tube design effectively prevents material from wearing down the inner wall of the drying cylinder body, extending the service life of the drying cylinder body. Furthermore, when the wear-resistant coated tube wears to a certain extent, it can be easily and quickly disassembled and replaced. The inner wall surface of the wear-resistant coated tube 7 is provided with a spiral-shaped guide groove 8, which guides residual material towards the discharge port, preventing material residue inside the drying cylinder and reducing cleaning workload. A hot air conveying pipe 13 is installed at an opening on the lower side surface of the drying cylinder body 1. A hot air generator 14 is installed at the end of the hot air conveying pipe 13. The hot air generated by the hot air generator 14 enters the interior of the drying cylinder body 1 through the hot air conveying pipe 13 to dry the material. A hot air recovery mechanism 15 is installed at an opening on the upper side surface of the drying cylinder body 1. The hot air recovery mechanism 15 is used to recover the waste heat generated during the drying process and transfer the waste heat to the hot air generator 14 for reuse, effectively improving energy utilization and reducing energy consumption.

[0023] A cleaning door 11 is provided on the side of the drying cylinder body 1. The cleaning door 11 is hinged to the drying cylinder body 1 and is equipped with a sealing strip to ensure the airtightness of the drying cylinder body. A handle 12 is provided on the edge of the cleaning door 11 for easy opening and closing by operators, facilitating cleaning and maintenance of the interior of the drying cylinder body. Both the feed pipe 3 and the discharge pipe 4 are equipped with feed and discharge filters, both made of stainless steel, which effectively filter impurities in the material and ensure the quality of the output. The bottom of the drying cylinder body 1 has a conical structure, which facilitates material concentration at the discharge port, accelerates the discharge speed, and reduces material residue.

[0024] Working principle and process: When using this three-in-one dryer, the material is first conveyed into the drying cylinder body 1 through the feed pipe 3, and the electromagnetic control valve is opened to control the feed rate. Then, the drive motor 6 is started, which drives the stirring paddle 5 to rotate and mix the material. At the same time, the hot air generator 14 is started, and hot air enters the drying cylinder body 1 through the hot air delivery pipe 13 to dry the material. During the drying process, the stirring paddle 5 continuously stirs the material, ensuring full contact between the material and the hot air, improving drying efficiency and uniformity.

[0025] The waste heat generated during the drying process is recovered by the hot air recovery mechanism 15 and transported to the hot air generator 14 for reuse. After the material is dried, the drive motor 6 and the hot air generator 14 are turned off, and the electromagnetic control valve of the discharge pipe 4 is opened. Under the guidance of its own gravity and the guide groove 8 on the inner wall of the wear-resistant coated pipe 7, the material is discharged through the discharge pipe 4.

[0026] After the equipment has been used for a period of time, if it is necessary to clean the inside of the drying cylinder body or check the wear condition of the wear-resistant coating tube 7, the cleaning door 11 can be opened by the handle 12. If the wear-resistant coating tube 7 is severely worn, it can be removed from the inner wall of the drying cylinder body 1 by the locking block 9 and the locking groove 10 for replacement.
