Description

Technical Field

[0001] This utility model belongs to the field of vacuum drying oven technology, and specifically relates to a surround-type water-cooled rapid cooling vacuum drying oven device. Background Technology

[0002] A vacuum drying oven is a device that uses vacuum technology to dry materials under negative pressure. By reducing the air pressure around the material, it causes the moisture or other volatile components in the material to evaporate rapidly at a lower temperature. It is particularly suitable for drying heat-sensitive, easily decomposed and easily oxidized substances, as well as items with complex compositions.

[0003] A search revealed a vacuum drying oven disclosed in Chinese utility model patent publication number CN215832316U. This vacuum drying oven, by incorporating an air exchange component, extracts moisture from the drying chamber to the outside of the chamber, reducing the risk of moisture condensing and falling back into the material, thus improving drying efficiency. The inclined top wall of the drying chamber allows condensate to flow into a water storage tank under its own gravity, facilitating the storage of condensate and minimizing its fall into the drying chamber. Heating elements facilitate temperature increases within the drying chamber, increasing the vaporization rate of moisture and decreasing the condensation rate, thereby improving the drying efficiency of the material.

[0004] However, this vacuum drying oven does not have a rapid cooling function. After drying the items, the vacuum drying oven heats the samples. The temperature inside the oven is high after drying, so it is necessary to wait for the internal temperature of the oven to cool down before the next vacuum drying process can be carried out. This greatly reduces the efficiency of the device. Therefore, a surround water-cooled rapid cooling vacuum drying oven device is proposed. Utility Model Content

[0005] To address the aforementioned problems in the prior art, namely the slow cooling speed of vacuum drying ovens, this invention provides a surround-type water-cooled rapid cooling vacuum drying oven device.

[0006] This application discloses a surround-type water-cooled rapid cooling vacuum drying oven device, which adopts the following technical solution:

[0007] A surround-type water-cooled rapid cooling vacuum drying oven device includes a box body, a vacuum treatment component installed on the box body to perform vacuum treatment inside the box body, and a first cooling component and a second cooling component to perform external and internal cooling of the box body.

[0008] The first cooling assembly includes a water tank fixedly connected to the housing, a partition fixedly connected to the water tank dividing the water tank into upper and lower layers, a semiconductor cooler arranged in the water tank and located below the partition to cool the coolant filled in the water tank, a submersible pump installed in the water tank, and a heat exchange coil connected to the submersible pump.

[0009] One end of the heat exchange coil is connected to the submersible pump, and the other end is connected to the water tank and communicates with the coolant in the water tank.

[0010] A heat exchange box is also installed on the outside of the box body. The heat exchange coil is inserted into the heat exchange box. A heat exchange fan is installed in the heat exchange box. The air blown out by the heat exchange fan comes into contact with the heat exchange coil. Ventilation holes are provided on the heat exchange box.

[0011] By adopting the above technical solution, the operation is carried out according to the following steps: First, the interior of the chamber is vacuum-dried using the vacuum treatment component; then, the interior temperature is initially cooled by conducting cold air from the outside using the first cooling component; finally, the interior temperature is further cooled by directly generating cold air and sending it into the chamber using the second cooling component. When cooling the chamber using the first cooling component, the semiconductor cooler is turned on to cool the coolant in the water tank. Then, the submersible pump is turned on to extract the cooled coolant and transfer it to the heat exchange coil inside the coolant heat exchange tank. The heat exchange fan is then turned on to blow the cold air generated by the coolant heat exchange onto the chamber, thereby conducting cold air onto the outer surface of the chamber and initially reducing the interior temperature. The cooled coolant returns to the storage chamber through the other end of the heat exchange coil and is cooled again, thus achieving recycling.

[0012] Optionally, a drive motor is installed in the water tank. The drive motor is fixedly connected to the partition, and a stirring rod is fixedly connected to the shaft of the drive motor. The top end of the stirring rod penetrates the partition, and the coolant is stirred by the drive motor.

[0013] By adopting the above technical solution, the drive motor is turned on to drive the stirring rod to rotate, and the rotation of the stirring rod ensures that the coolant undergoes a uniform cooling process.

[0014] Optionally, two heat exchange boxes are provided, respectively arranged on both sides of the box body; a Y-shaped pipe communicating with the submersible pump is installed on the top of the submersible pump, the lower end of the Y-shaped pipe is connected to the submersible pump, and the other two ends are respectively connected to two heat exchange coils; each heat exchange coil is connected to a heat exchange box.

[0015] Optionally, the heat exchange coils are arranged in a tortuous manner within the heat exchange box.

[0016] Optionally, the second cooling assembly includes an equipment box fixedly connected to the housing, a compressor installed in the equipment box and connected to the outside of the equipment box via an air intake pipe, an air exchanger connected to the compressor via a first air supply pipe, an oil-free converter connected to the air exchanger via a second air supply pipe and a third air supply pipe, a dryer connected to the air exchanger via a fourth air supply pipe, and a partition plate dividing the equipment box into upper and lower layers; the compressor, air exchanger, dryer, and oil-free converter are installed on the lower side of the partition plate and arranged in the equipment box; the air outlet of the dryer is connected to the upper side of the partition plate; the front of the equipment box is connected to the back of the housing via a valve pipe.

[0017] By adopting the above technical solution, when using the second cooling component to cool the box, the compressor is turned on to draw air into the compressor for compression. The compressed air is then sent to the air exchanger for preheating. After preheating, the air is sent to the oil-free converter for further filtration and purification, making it drier and cleaner. Finally, this air is sent back to the air exchanger for cooling. The cooled compressed air then enters the dryer to remove moisture. Finally, this cold air is sent into the interior of the box for rapid heat dissipation and cooling from the inside.

[0018] Optionally, a second fan is installed on the enclosure, and multiple second fans are provided. The front of the equipment enclosure is fixedly connected to the back of the enclosure through multiple valve pipes, and a second fan is fixedly installed inside each valve pipe.

[0019] By adopting the above technical solution, the second fan accelerates the entry of cold air into the cabinet for cooling.

[0020] Optionally, the vacuum processing assembly includes a vacuum pump fixedly connected to the housing; the housing is equipped with a temperature sensor and a vacuum sensor to detect the internal environment of the housing.

[0021] Optionally, the temperature sensor and vacuum sensor are mounted on the inner wall of the enclosure.

[0022] Optionally, a vent valve is fixedly connected to the upper part of the box, and the vent valve communicates with the inside of the box.

[0023] The beneficial effects of this utility model are as follows: The surround-type water-cooled rapid cooling vacuum drying oven device can perform vacuum drying on the items inside the oven through the set vacuum treatment components. After vacuum drying, the set first cooling component conducts cold air from the outside to initially cool down the internal temperature of the oven. Then, the set second cooling component generates cold air and sends it into the interior of the oven to perform secondary cooling from the inside. By using two different methods, the internal temperature is cooled down simultaneously, which facilitates the rapid reduction of the temperature of the oven. Attached Figure Description

[0038] Reference Figure 4 , Figure 5 Two heat exchange boxes 309 are installed on the outside of the housing 1, one on each side of the housing 1. Heat exchange coils 308 extend into the heat exchange boxes 309 and are arranged in a zigzag pattern within them to increase their length. A heat exchange fan 310 is installed in each heat exchange box 309, blowing air that contacts the heat exchange coils 308. Ventilation holes are provided on the heat exchange boxes 309. Both the water tank 301 and the heat exchange boxes 309 are flush with the outer wall of the housing 1, and the heat exchange coils 308 are also flush with the outer wall of the housing 1.

[0039] When the first cooling component 3 is used to cool the housing 1, the semiconductor cooler 305 is turned on to cool the coolant inside the water tank 301. At the same time, the drive motor 303 is turned on to drive the stirring rod 304 to rotate. The rotation of the stirring rod 304 ensures that the coolant undergoes a uniform cooling process. Then, the submersible pump 306 is turned on to extract the cooled coolant and send it into the heat exchange coils 308 inside the two heat exchange boxes 309 through the Y-tube 307. Then, the heat exchange fan 310 is turned on to blow the coolant-generated cold air towards the housing 1, thereby conducting cold air onto the outer surface of the housing 1 and initially reducing the temperature inside the housing 1. The cooled coolant will return to the inside of the liquid storage chamber through the other end of the heat exchange coil 308 and be cooled again. This process is repeated to achieve the purpose of recycling.

[0040] Reference Figure 4 , Figure 6 The second cooling assembly 4 includes an equipment box 401 fixedly connected to the back of the housing 1, which is mounted on the upper side of the water tank 301. A compressor 402 is installed in the equipment box 401. An air intake pipe 407 is installed on one side of the compressor 402, with one end connected to the compressor 402 and the other end extending out of the equipment box 401 to draw in outside air. A first air supply pipe 408 is installed on the other side of the compressor 402, with one end connected to the compressor 402 and the other end connected to an air exchanger 403. An oil-free converter 404 is connected to the air exchanger 403 via a second air supply pipe 409 and a third air supply pipe 410, and is installed in the equipment box 401. A dryer 405 is also connected to the air exchanger 403 via a fourth air supply pipe 411, and is also located in the equipment box 401.

The front of the equipment box 401 and the back of the housing 1 are fixedly connected by multiple valve pipes, and a second fan 406 is fixedly installed inside each valve pipe.

[0041] When using the second cooling component 4 to cool the housing 1, the compressor 402 is turned on to draw air into the compressor 402 for compression. The compressed air is then sent to the air exchanger 403 for preheating. After preheating, the air is sent to the oil-free converter 404 for further filtration and purification, making it drier and cleaner. Finally, this air is sent back to the air exchanger 403 for cooling. The cooled compressed air then enters the dryer 405 to remove moisture. Finally, this cold air is sent into the housing 1 by the second fan 406 for rapid heat dissipation and cooling from the inside.

[0042] In practice, the following steps are followed: First, the vacuum processing component 2 performs a vacuum drying process on the inside of the chamber 1; then, the first cooling component 3 conducts cold air from the outside to initially cool the inside of the chamber 1; finally, the second cooling component 4 generates cold air and, through a valve pipe and a second fan 406, sends the cold air into the inside of the chamber 1 for secondary cooling. In summary, this surround-type water-cooled rapid cooling vacuum drying oven device can perform vacuum drying on the items inside the chamber 1 using the vacuum processing component 2. After vacuum drying, the first cooling component 3 conducts cold air from the outside to initially cool the inside of the chamber 1. Then, the second cooling component 4 generates cold air and sends it into the inside of the chamber 1 for secondary cooling. These two different methods achieve simultaneous internal cooling, facilitating a rapid decrease in the temperature of the chamber 1.
