Description

Technical Field

[0001] This utility model relates to the field of vacuum dryer technology, and in particular to a material turning mechanism for a vacuum dryer. Background Technology

[0002] Vacuum dryers are widely used in industries such as chemical, food, pharmaceutical and bioengineering to remove moisture or volatile components from materials, improve product stability and shelf life. They transfer heat efficiently at low temperature under low pressure, promoting rapid evaporation of moisture. The drying process is carried out in a sealed container to avoid external contamination and reduce the risk of thermal degradation of heat-sensitive materials. They are suitable for processing materials that are easily deteriorated, oxidized or deactivated.

[0003] However, in practical applications, traditional vacuum dryers generally suffer from uneven heating and low drying efficiency when processing granular, powdery, or viscous materials. This is because most existing equipment adopts a static drying method and lacks an effective dynamic turning device, making it impossible to achieve continuous stirring or periodic turning of the material. This design defect leads to prolonged drying time and reduced production efficiency. At the same time, the material is prone to accumulation, clumping, or even adhering to the cylinder wall during the drying process, further affecting heat transfer efficiency and drying uniformity, ultimately resulting in unstable product quality and difficulty in meeting the requirements of precision manufacturing processes.

[0004] Therefore, it is necessary to design a material turning mechanism for a vacuum dryer to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional vacuum dryers, such as uneven heating of materials, low drying efficiency, and unstable product quality due to the lack of dynamic turning function, this utility model provides a material turning mechanism for a vacuum dryer.

[0006] The technical solution is as follows: A material turning mechanism for a vacuum dryer includes a foot frame, a first support, a drum, bearings, a motor, a stirring shovel, a second support, a pulley set, a gear, a gear ring, a rotating shaft, and a cylinder cover. The first support is fixedly connected to the top left and right sides of the foot frame. Multiple bearings are evenly installed on the inner walls of the two first supports. The drum is rotatably connected between the two first supports through the bearings. Multiple connecting holes are evenly opened along the circumferential direction on the right outer wall of the drum. The second support is fixedly connected to the top left side of the foot frame. A motor is fixedly connected to the top of the second support. The output shaft of the motor extends into the drum and is connected to the stirring shovel. A rotating shaft is rotatably connected to the top left side of the foot frame. A pulley set is connected between the output shaft of the motor and the rotating shaft. A gear is fixedly connected to the right side of the rotating shaft. A gear ring is fixedly connected to the left outer wall of the drum. The gear meshes with the gear ring. A cylinder cover is installed on the right side of the drum.

[0007] Furthermore, both the roller and the mixing spatula are made of stainless steel.

[0008] Furthermore, the bearings are made of chrome steel.

[0009] Furthermore, it also includes an air valve, which is installed on the right side of the middle part of the cylinder cover.

[0010] Furthermore, it also includes a pressure detector, which is fixedly connected to the right side of the front of the cylinder cover.

[0011] Furthermore, it also includes locking screws. Multiple locking screws are evenly threaded along the circumferential direction on the outer wall of the cylinder cover. After passing through the cylinder cover, the locking screws are threadedly connected to the connecting holes on the roller.

[0012] The beneficial effects are: 1. This utility model uses a motor to drive the stirring shovel to rotate, and combined with the gear ring transmission to drive the drum to rotate slowly, to achieve a double tumbling effect on the material, so that the material is continuously stirred and rolled inside the drum, effectively improving the uniformity of heating and the efficiency of moisture evaporation, thereby significantly improving the overall drying effect.

[0013] 2. This utility model uses evenly distributed locking screws on the outer wall of the cylinder cover to cooperate with the roller connection hole to ensure a sealing effect; at the same time, it is equipped with an air valve and an air pressure detector to achieve precise control and real-time monitoring of the vacuum degree inside the roller, ensuring the stable operation of the drying process.

[0014] 3. This utility model uses stainless steel for both the drum and the mixing shovel, which has excellent corrosion resistance. It is especially suitable for processing materials containing water or chemical components, and can effectively prevent equipment damage caused by long-term contact with corrosive substances, thus extending the service life of the equipment.

[0015] 4. This utility model uses chromium steel for the bearings, which has high hardness, high strength and good wear resistance, and can maintain a long working life under heavy load and high speed operation, thereby improving the stability and reliability of the whole machine operation.

Detailed Implementation

[0022] Example: A material turning mechanism for a vacuum dryer, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a leg 1, a support 101, a roller 2, bearings 201, a motor 4, a mixing shovel 5, a second support 6, a pulley set 7, a gear 8, a gear ring 9, a rotating shaft 10, and a cylinder cover 11. Supports 101 are screwed onto the top left and right sides of the leg 1. Multiple bearings 201, made of chrome steel, are evenly installed on the inner walls of the two supports 101. The roller 2 is rotatably connected between the two supports 101 via the bearings 201. Multiple connecting holes 3 are evenly distributed along the circumference on the right outer wall of the roller 2. The leg 1... A bracket 2 6 is installed on the top left side by screws. A motor 4 is installed on the top of the bracket 2 6 by screws. The output shaft of the motor 4 extends into the inside of the drum 2 and is connected to a stirring shovel 5. Both the drum 2 and the stirring shovel 5 are made of stainless steel. A rotating shaft 10 is rotatably connected to the top left side of the foot 1. A pulley group 7 is connected between the output shaft of the motor 4 and the rotating shaft 10. A gear 8 is connected to the right side of the rotating shaft 10 by welding. A gear ring 9 is connected to the outer wall of the left side of the drum 2 by welding. The gear 8 meshes with the gear ring 9. A drum cover 11 is installed on the right side of the drum 2.

[0023] like Figure 1 and Figure 5 As shown, it also includes an air valve 12, an air pressure detector 13, and a locking screw 14. The air valve 12 is installed on the right side of the middle part of the cylinder cover 11, and the air pressure detector 13 is installed on the right side of the front part of the cylinder cover 11 by means of screws. Multiple locking screws 14 are evenly threaded along the circumferential direction on the outer wall of the cylinder cover 11. After passing through the cylinder cover 11, the locking screws 14 are threadedly connected to the connecting hole 3 on the roller 2.

[0024] When using this device, first place the material turning mechanism of the vacuum dryer on a flat surface, connect the power supply, and check whether the motor 4, air valve 12, air pressure detector 13, and other components are operating normally. Then, open the cylinder cover 11, confirm that the inside of the drum 2 is clean and free of debris, put the material to be dried into the drum 2, close the cylinder cover 11, and tighten the locking screw 14 on the outer wall to ensure a firm connection between the cylinder cover 11 and the drum 2, thereby ensuring good sealing and structural stability. Next, use the air valve 12 to evacuate the inside of the drum 2 to form the desired vacuum. A low-pressure environment is required. Simultaneously, the reading of the pressure detector 13 is observed. After confirming that the set vacuum level has been reached, the drying operation begins. After starting the motor 4, its output shaft drives the stirring shovel 5 to rotate inside the drum 2, turning the material and promoting uniform evaporation of moisture. At the same time, the pulley assembly 7 mounted on the output shaft of the motor 4 transmits power to the rotating shaft 10. A gear 8 is fixed to the right end of the rotating shaft 10, and this gear 8 meshes with a gear ring 9 on the outer left side of the drum 2, thereby driving the drum 2 to rotate slowly. Under the combined action of the rotating stirring shovel 5 and the rotating drum 2, the material is continuously turned over. The process significantly improves drying efficiency and uniformity. Both the drum 2 and the stirring shovel 5 are made of stainless steel, offering excellent corrosion resistance and hygiene, making them particularly suitable for materials containing water or chemicals. This effectively prevents corrosion from prolonged contact with these substances, extending the equipment's lifespan. Furthermore, the bearing 201 is made of chromium steel, possessing high hardness, high strength, and excellent wear resistance, ensuring a long service life under heavy loads and high-speed operation, guaranteeing stable equipment operation. Throughout the drying process, the pressure detector 13 must be monitored in real-time to ensure a stable vacuum environment inside the drum 2. Adjustments to the drum 2's speed or stirring frequency can be made through the control system. After drying, the motor 4 is turned off, and the air valve 12 is slowly opened to release the vacuum. Once the internal and external pressures are balanced, the locking screw 14 is loosened, and the drum cover 11 is opened to remove the dried material. Finally, the residue inside the drum 2 is cleaned, the equipment surface is wiped, and the moving parts such as the bearing 201, gear 8, and pulley group 7 are checked for wear. If necessary, lubricating oil is added or easily worn parts are replaced. The above preparation work can be repeated before the next use.
