Description

Technical Field

[0001] This utility model relates to the field of drying devices for refrigerant dehydration, and more specifically, to a refrigerant dehydration drying device. Background Technology

[0002] Refrigerant is the working fluid that completes the thermodynamic cycle in a refrigeration machine. It absorbs heat from the object being cooled at a low temperature and then transfers it to cooling water or air at a higher temperature. In vapor compression refrigeration machines, refrigerants that can be liquefied at room temperature or lower are used, such as Freon (fluorine, chlorine, and bromine derivatives of saturated hydrocarbons), azeotropic mixtures (azeotropic solutions composed of two Freon compounds mixed in a certain proportion), hydrocarbons (propane, ethylene, etc.), ammonia, etc. The water content in the refrigerant is an important indicator of its quality; therefore, dehydration and drying are necessary during refrigerant processing.

[0003] After searching, it was found that application number CN202221476700.4, entitled "A Drying Device for Removing Water from Fluorine Refrigerants," addresses the issue that existing dehydration drying devices rely on a single drying method, resulting in insufficient drying of the refrigerant. Furthermore, it is inconvenient to monitor the humidity of the dried refrigerant at any time, failing to promptly detect the desiccant's reduced effectiveness and leading to the leakage of large amounts of insufficiently dried refrigerant. This application proposes a multi-stage drying process to achieve more thorough dehydration and significantly reduce the water content in the refrigerant. Simultaneously, a humidity meter can continuously monitor the humidity of the discharged refrigerant to prevent the leakage of large amounts of insufficiently dried refrigerant, thus ensuring refrigerant quality. However, this application uses absorbent cotton, a dehydrating filter element, and a desiccant for drying the refrigerant. The absorbent cotton and dehydrating filter element become saturated, requiring shutdown and replacement, causing discontinuous operation. Similarly, the desiccant also needs replacement after saturation, which is cumbersome. Moreover, the desiccant becomes ineffective after saturation and is a consumable; frequent replacement of consumables increases production costs, affecting work efficiency and economy. Further improvements are warranted.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0008] To achieve the aforementioned advantages of high work efficiency and improved production economy, the specific technical solution adopted by this utility model is as follows:

[0009] A refrigerant dehydration and drying device includes a tunnel-type quick-freezing machine and a separation chamber. The separation chamber is installed on one side of the tunnel-type quick-freezing machine, and a liquid delivery pipe is arranged through the inside of the tunnel-type quick-freezing machine, with the liquid outlet of the liquid delivery pipe extending into the separation chamber.

[0011] Furthermore, a first drive motor is fixedly installed on the front face of the separation box, and the output end of the first drive motor is fixedly connected to one end of the roller shaft of the drive roller.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a refrigerant dehydration and drying device, which has the following beneficial effects:

[0019] (1) This utility model employs a tunnel-type quick-freezing machine and a separating mesh belt. The refrigerant flows inside the delivery pipe. When passing through the tunnel-type quick-freezing machine, the low temperature inside causes the water inside the refrigerant to freeze into ice crystals. Since the freezing point of the refrigerant is much lower than that of water, the refrigerant remains in a liquid state. When flowing out of the delivery pipe, the ice crystals and refrigerant flow to the top surface of the separating mesh belt. The ice crystals remain on the top surface of the separating mesh belt, while the refrigerant flows to the bottom of the separation chamber on the left side of the partition and is discharged along the drain pipe, completing the dehydration and drying process. Driven by the drive roller, the device rotates continuously, and the ice crystals are transported to the right side of the partition and fall into the separation box inside the partition. At the same time, the water pump pumps cleaning water, which is sprayed out through the nozzle to melt and clean the remaining ice crystals. The blower generates airflow, which is blown out through the nozzle to dry the separation mesh belt, thus completing the continuous separation. This device utilizes the different freezing points of the refrigerant and the internal water to achieve continuous and uninterrupted separation. At the same time, it eliminates the problem of increased enterprise costs caused by the use of desiccants and other consumables, significantly improving work efficiency and economy.

[0020] (2) This utility model adopts ball hitting. During separation, the second drive motor drives the rotating shaft to rotate, which drives the ball hitting to hit the separation mesh belt, thereby improving the vibration effect of the separation mesh belt, accelerating the screening process, improving separation efficiency, reducing clogging, and further improving work efficiency.

Figure 1-4As shown, a refrigerant dehydration and drying device according to an embodiment of the present invention includes a tunnel-type quick-freezing machine 2 and a separation chamber 3. The separation chamber 3 is installed on one side of the tunnel-type quick-freezing machine 2, and a liquid delivery pipe 1 is arranged through the tunnel-type quick-freezing machine 2. The tunnel-type quick-freezing machine 2 is a common device. The liquid delivery pipe 1 adopts a continuous S-shaped structure to improve the quick-freezing effect, and the liquid outlet end of the liquid delivery pipe 1 extends into the separation chamber 3.

The surface of the separation mesh belt 5 is densely covered with... The separation chamber 3 has a screen and a partition 9 is fixedly installed below the separating mesh belt 5 on the bottom surface. A water pump 10 is fixedly installed on the top surface of the separation chamber 3, and a water supply pipe 11 is connected to the output end of the water pump 10.

A blow pipe 13 is connected to the surface of the air supply pipe 20. A blow pipe 13 is connected to the surface of the blow pipe 13. At nozzle 14, the refrigerant flows inside the liquid delivery pipe 1. As it passes through the tunnel-type quick-freezing machine 2, the low temperature inside causes the water inside the refrigerant to freeze into ice crystals. Since the freezing point of the refrigerant is much lower than that of water, the refrigerant remains in a liquid state. As it flows out of the liquid delivery pipe 1, the ice crystals and refrigerant flow to the top surface of the separating mesh belt 5. The ice crystals remain on the top surface of the separating mesh belt 5, while the refrigerant flows to the bottom of the separating box 3 on the left side of the partition 9 and is discharged along the drain pipe 15, completing the dehydration and drying process. The separating mesh belt 5 is driven by the drive roller 4. As the system continues to rotate, ice crystals are transported to the right side of partition 9 and fall into the separation chamber 3 on the right side of partition 9. At the same time, water pump 10 pumps cleaning water, which is sprayed out through nozzle 12 to melt and clean the remaining ice crystals. Blower 19 generates airflow, which is blown out through nozzle 14 to dry the separation mesh belt 5, thus completing continuous separation. This device utilizes the different freezing points of refrigerant and internal water to achieve continuous and uninterrupted separation. At the same time, it eliminates the problem of increased enterprise costs caused by the use of desiccants and other consumables, significantly improving work efficiency and economy.

[0031] In one embodiment, a rotating shaft 6 is rotatably connected inside the separation box 3, and a striking rod 7 is fixedly connected to the surface of the rotating shaft 6. A striking ball 8 is fixedly connected to the other end of the striking rod 7. A second drive motor 18 is fixedly installed on the front of the separation box 3, and the output end of the second drive motor 18 is fixedly connected to one end of the rotating shaft 6. Multiple sets of rotating shafts 6 are arranged, and the distance between the rotating shaft 6 and the top surface of the separation mesh belt 5 is less than the length of the striking rod 7, ensuring that the striking ball 8 can hit the separation mesh belt 5. During separation, the second drive motor 18 drives the rotating shaft 6 to rotate, which in turn drives the striking ball 8 to rotate, hitting the separation mesh belt 5, improving the vibration effect of the separation mesh belt 5, thereby accelerating the screening process, improving separation efficiency, reducing clogging, and further improving work efficiency.

[0032] In one embodiment, a first drive motor 17 is fixedly installed on the front of the separation box 3, and the output end of the first drive motor 17 is fixedly connected to one end of the roller shaft of the drive roller 4, which is a common drive structure.

[0034] In one embodiment, multiple sets of nozzles 14 are arranged, and the air outlet direction of the nozzles 14 is directly facing the separating mesh belt 5, which facilitates the rapid drying of the separating mesh belt 5.

[0035] In one embodiment, both the nozzle 12 and the blowhole 14 are located on the right side of the partition 9, and both ends of the partition 9 are sealed to the inner wall of the separation box 3 to facilitate the separation of water and refrigerant.

[0036] In one embodiment, the bottom of the separator 3 is connected to a drain pipe 15 and a drain pipe 16 at both ends to facilitate the discharge of water and refrigerant.

[0037] Working principle:

[0038] The refrigerant flows inside the delivery pipe 1. When it passes through the tunnel-type quick-freezing machine 2, the low temperature inside the tunnel-type quick-freezing machine 2 causes the water inside the refrigerant to freeze into ice crystals. Since the freezing point of the refrigerant is much lower than that of water, the refrigerant remains in a liquid state. When it flows out of the delivery pipe 1, the ice crystals and refrigerant flow into the top surface of the separating mesh belt 5. The ice crystals remain on the top surface of the separating mesh belt 5, while the refrigerant flows into the bottom of the separating box 3 on the left side of the partition 9 and is discharged along the drain pipe 15, completing the dehydration and drying process. The separating mesh belt 5 continues to rotate under the drive roller 4, and the ice crystals are transported to the right side of the partition 9 and fall into the separating box 3 on the right side of the partition 9. At the same time, the water pump 10 pumps cleaning water through the nozzle 1. 2. The airflow is sprayed out to melt and clean the residual ice crystals. The blower 19 generates airflow, which is blown out through the nozzle 14 to dry the separation mesh belt 5, thus completing continuous separation. This device utilizes the different freezing points of the refrigerant and the internal water to achieve continuous and uninterrupted separation. At the same time, it eliminates the problem of increased enterprise costs caused by the use of desiccants and other consumables, significantly improving work efficiency and economy. Meanwhile, during separation, the second drive motor 18 drives the rotating shaft 6 to rotate, which in turn drives the ball 8 to rotate, striking the separation mesh belt 5, improving the vibration effect of the separation mesh belt 5, thereby accelerating the screening process, improving separation efficiency, reducing clogging, and further improving work efficiency.
