Description

Technical Field

[0001] This utility model relates to the field of evaporator technology, specifically a multi-effect evaporator. Background Technology

[0002] In the field of refrigeration and heat exchange, the evaporator is a crucial piece of equipment used to convert liquid refrigerant into gas by absorbing heat. It is widely used in air conditioning, refrigeration equipment, the chemical industry, and many other sectors. However, with increasing usage time, many existing evaporators exhibit a series of problems during operation, including poor evaporation efficiency, unsatisfactory condensation, and frequent blockages. These problems not only lead to reduced refrigeration efficiency but can also cause system failures, increase maintenance costs, and affect the long-term stability of the equipment.

[0003] The core function of an evaporator is to allow the coolant or refrigerant to absorb heat and evaporate rapidly through contact with a heat source. However, many evaporators suffer from insufficient heat exchange efficiency during design or use, resulting in poor cooling performance. Common causes include insufficient heat exchange surface area, uneven refrigerant flow, surface fouling, or inadequate heat transfer.

[0004] The condensation process in the evaporator is crucial to the overall heat exchange efficiency of the system. When the evaporator's condensation is ineffective, the transition of the refrigerant between its gaseous and liquid states becomes obstructed, preventing the efficient release of heat. This can be caused by factors such as improper condenser piping design, insufficient heat exchange area, or mismatched condensing pressure, thus affecting the overall system's operating efficiency.

[0005] Evaporators are prone to blockage during prolonged use, especially when the refrigerant contains impurities, grease, or scale. These solid substances or deposits gradually accumulate on the evaporator pipes or fins, obstructing refrigerant flow and significantly reducing heat exchange efficiency. Blockage not only increases the burden on the equipment but can also lead to overheating, unstable operation, and in severe cases, even system failure. Currently, no solution has been proposed to address these technical problems. Utility Model Content

[0006] To address the problems in related technologies, this utility model proposes a multi-effect evaporator to overcome the aforementioned technical issues in existing technologies. The purpose of this utility model is to improve heat exchange efficiency, ensure that the refrigerant fully absorbs heat and transforms into a gaseous state during the evaporation process, accelerate the evaporation rate, improve the overall system cooling efficiency, reduce energy loss, avoid overheating problems caused by poor condensation, extend the service life of the equipment, reduce the risk of equipment failure, and at the same time maintain the uniformity of wastewater, prevent solid impurities from settling at the bottom of the wastewater tank, avoid sediment clogging the drainage pipes, and ensure that wastewater can be smoothly discharged into the external treatment system.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-effect evaporator, comprising a wastewater tank, an evaporator connected to the top of the wastewater tank via a pipe, a support provided on one side of the wastewater tank, a condensation mechanism provided on the support, several water inlets connected to the top of the wastewater tank, a sleeve fitted around the outside of the wastewater tank, a cooling pipe provided between the wastewater tank and the sleeve, a cylinder installed on the outer wall of the sleeve, a movable plate movably connected to the outer wall of the wastewater tank, the output end of the cylinder movably connected to the movable plate, and a driving stirrer provided on the movable plate.

The drive motor is fixedly mounted on a movable plate. One end of the rotating shaft is fixedly connected to the output end of the drive motor, and the other end of the rotating shaft passes through the top of the wastewater tank and extends into the interior of the wastewater tank.

[0009] Preferably, the condensation mechanism includes a second drive motor, a fan blade, a second cooling pipe, and a protective shell. The protective shell is mounted on a bracket, the second drive motor is mounted on the protective shell, the fan blade is mounted on the output end of the second drive motor, the second cooling pipe is disposed on the inner wall of the protective shell, and the interior of the second cooling pipe is filled with coolant.

[0011] Preferably, a water level sensor is installed inside the wastewater tank.

[0012] Preferably, the wastewater tank, pipes, sleeves, and protective shell are all made of metal materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This utility model is a multi-effect evaporator. By setting up a driving agitator, the uniformity of wastewater is maintained, and solid impurities are prevented from settling at the bottom of the wastewater tank. This effectively avoids the blockage of drainage pipes by sediments, ensuring that wastewater can be smoothly discharged into the external treatment system. The maintenance frequency of the evaporator and wastewater system is greatly reduced, reducing pipe blockage and system failures caused by sediments and dirt. This ensures smooth wastewater treatment, avoids the corrosive effect of impurities in the wastewater on the equipment, and thus extends the service life of the evaporator and other related equipment. This invention relates to a multi-effect evaporator. By incorporating a condensation mechanism, it effectively improves heat exchange efficiency, ensuring that the refrigerant fully absorbs heat and transforms into a gaseous state during evaporation, thereby accelerating the evaporation rate, improving the overall system's refrigeration efficiency, reducing energy loss, and ensuring that the refrigerant can smoothly transform into a liquid state during condensation, releasing excess heat. This, in turn, improves the energy efficiency and stability of the entire refrigeration system. Effective condensation not only maintains the system's temperature balance but also avoids overheating problems caused by poor condensation, extending the equipment's service life and reducing the risk of equipment failure.

[0018] Please see Figure 2 As shown, the driving agitator 9 further includes a driving motor 901, a rotating shaft 902, and a stirring rod 903 disposed on the outer surface of the rotating shaft 902. The driving motor 901 is fixedly mounted on the movable plate 8. One end of the rotating shaft 902 is fixedly connected to the output end of the driving motor 901, and the other end of the rotating shaft 902 passes through the top of the wastewater tank 1 and extends into the interior of the wastewater tank 1.

[0019] In this embodiment, the drive motor 901 is started to drive the rotating shaft 902 fixedly connected to it to rotate, thereby causing the stirring rod 903 on the outer surface of the rotating shaft 902 to stir the wastewater and prevent the pipe 2 from becoming blocked.

[0020] Please see Figure 1 and Figure 3 As shown, the condensation mechanism further includes a second drive motor 10, a fan blade 11, a second cooling pipe 12, and a protective shell 13. The protective shell 13 is mounted on the bracket 4, the second drive motor 10 is mounted on the protective shell 13, the fan blade 11 is mounted on the output end of the second drive motor 10, and the second cooling pipe 12 is disposed on the inner wall of the protective shell 13.

[0021] In this embodiment, the second drive motor 10 is started to drive the fan blade 11 fixedly connected to it to rotate, thereby cooling the pipe 2. The coolant inside the second cooling pipe 12 can further improve the cooling effect.

[0022] Please see Figure 1 As shown, a pump body 14 is further installed on the pipeline 2.

[0028] The working principle of this utility model: By setting up a drive agitator 9, the drive motor 901 is started to drive the rotating shaft 902 fixedly connected to it to rotate, thereby causing the stirring rod 903 on the outer surface of the rotating shaft 902 to stir the wastewater and prevent the pipe 2 from becoming blocked.

Effective condensation not only maintains the system temperature balance but also avoids overheating caused by poor condensation, extending the equipment's service life and reducing the risk of equipment failure. It maintains the uniformity of wastewater, prevents solid impurities from settling at the bottom of the wastewater tank, effectively avoids sediment clogging of drainage pipes, and ensures that wastewater can be smoothly discharged into the external treatment system. Because clogging is effectively prevented, the maintenance frequency of the evaporator and wastewater system is greatly reduced, reducing pipe blockage and system failures caused by sediment and dirt, ensuring smooth wastewater treatment, and avoiding the corrosive effect of impurities in the wastewater on the equipment, thereby extending the service life of the evaporator 2 and other related equipment.
