Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of evaporator cleaning, and in particular to a rapid evaporator cleaning device. Background Technology
[0002] Evaporator cleaning equipment is a specialized device or system used to remove dirt, mineral deposits, and other impurities accumulated inside the evaporator. Over time, these deposits can affect the evaporator's efficiency, increase energy consumption, and potentially damage the equipment.
[0003] A plate evaporator, disclosed in CN206488511U, includes a left end cover (4) and a right end cover (2). A heat exchange zone (1) and a drying zone (3) are located between the left end cover (4) and the right end cover (2). The heat exchange zone (1) consists of stacked heat exchange plates. The drying zone (3) is a plate with an internal cavity containing a drying channel. A first fluid inlet (31) is located on one side of the drying zone (3) near the heat exchange zone (1), and a first fluid outlet (32) is located on the other side. The first fluid inlet (31) and the first fluid outlet (32) are connected by the drying channel. A through hole (33) not connected to the drying channel is also provided on the drying zone (3). In this invention, the refrigerant in the heat exchanger is dried through the drying zone, and the drying process can be cyclical, ensuring no impact on the low-temperature system. Furthermore, any residual moisture in the drying zone can be carried away by other fluids when not in use, resulting in a long service life.
[0004] While plate heat exchangers in the aforementioned technologies possess high heat exchange efficiency, their complex and tightly packed stacked structure makes regular cleaning of the heat exchange plates difficult. This leads to the accumulation of deposits, such as impurities and dirt, on the surface of the heat exchange plates, severely impacting heat exchange efficiency. The accumulation of deposits not only reduces the heat exchange performance of the heat exchanger but may also cause damage due to localized overheating, thereby affecting the stable operation and service life of the overall system. Utility Model Content
[0005] This invention solves the problems in related technologies and proposes a rapid evaporator cleaning device. The cleaning components use backwashing force to physically clean the inner wall of the heat exchange plate, while the ultrasonic generator performs ultrasonic cleaning on the surface of the heat exchange plate and the protective shell from the outside. Finally, the wastewater after cleaning is discharged through the drain pipe, thereby achieving automatic, efficient and thorough cleaning of the heat exchange plate, ensuring that the heat exchange efficiency is not affected and effectively extending the service life of the equipment.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a rapid evaporator cleaning device, comprising an upward-facing protective shell, a liquid inlet on one side of the protective shell, a liquid outlet on the other side of the protective shell, pressure sensors respectively installed on the liquid inlet and the liquid outlet, a heat exchange plate installed in the inner cavity of the protective shell, a mounting base fixedly installed in the inner cavity of the protective shell for installing the heat exchange plate, a handle installed on the upper surface of the heat exchange plate, a sealing cover plate installed on the upper surface of the protective shell, a cleaning component penetrating the sealing cover plate and installed in the inner cavity of the heat exchange plate, an ultrasonic generator installed in the inner cavity of the protective shell, a drain pipe installed on the lower surface of the protective shell, and a drain valve installed on the drain pipe.
[0007] By adopting the above technical solution, condensate enters the inner cavity of the protective shell through the inlet, exchanges heat through the heat exchange plates, and is discharged through the outlet. During long-term use, deposits will accumulate on the inner wall of the heat exchange plates. The pressure sensor detects the pressure difference between the inlet and outlet in real time. When the pressure difference increases, it indicates that the resistance caused by the deposits has increased. At this time, the drain valve opens, and the cleaning components use backwashing force to physically clean the inner wall of the heat exchange plates. At the same time, the ultrasonic generator performs ultrasonic cleaning on the surface of the heat exchange plates and the protective shell from the outside. Finally, the wastewater after cleaning is discharged through the drain pipe, thereby achieving automatic, efficient, and thorough cleaning of the heat exchange plates, ensuring that the heat exchange efficiency is not affected, and effectively extending the service life of the equipment.
[0008] As a preferred embodiment, the sealing cover is detachably connected to the protective housing, and the cleaning mechanism is connected to the sealing cover.
[0009] By adopting the above technical solution, the sealing cover and the protective shell are designed to be detachably connected, and the cleaning mechanism is connected to the sealing cover, so that the sealing cover can be moved easily. This allows the cleaning mechanism to be removed from the protective shell for maintenance, ensuring that the cleaning components can efficiently complete the cleaning task and maintain a good cleaning effect.
[0010] As a preferred embodiment, the heat exchange plate and the inner cavity of the protective shell are configured with the same curvature, and the heat exchange plate and the mounting base are connected by a snap-fit structure.
[0011] By adopting the above technical solution, the heat exchange plate and the inner cavity of the protective shell are set with the same curvature and connected to the mounting base through a snap-fit structure, making the heat exchange plate easy to disassemble and assemble, thus facilitating its maintenance, ensuring that it can effectively perform heat exchange operations, and guaranteeing the normal operation of the entire system.
[0012] As a preferred embodiment, the cleaning component is rotatably connected to the sealing cover plate, a drive motor is fixedly connected to the sealing cover plate and connected to the rotating shaft, a cleaning main pipe is connected to the other end of the rotating shaft, a water inlet port is provided on the lower end face of the cleaning main pipe, a support base is provided on the outer periphery of the water inlet port, a limiting bracket is evenly provided on the outer periphery of the support base and between it and the mounting base, and a cleaning brush is provided on the cleaning main pipe and communicates with it.
[0013] By adopting the above technical solution, when the pressure difference increases, the liquid inside the protective shell enters the cleaning main pipe through the water inlet port. The cleaning liquid in the cleaning main pipe enters the cleaning brush connected to it, and the drive motor starts, driving the rotating shaft to rotate. When the rotating shaft rotates, it drives the cleaning main pipe to rotate, thereby causing the cleaning main pipe to drive the cleaning brush to scrub the inner wall of the heat exchange plate.
[0014] As a preferred embodiment, a sealed bearing is provided at the connection between the support base and the water inlet port.
[0015] By adopting the above technical solution, a sealed bearing is installed between the support base and the water inlet port when the cleaning main pipe is rotating, ensuring that the liquid can pass smoothly through the water inlet port when the cleaning main pipe is rotating, and preventing the liquid from accumulating in the cleaning main pipe.
[0016] As a preferred embodiment, one end of the limiting bracket is fixedly connected to the support base, and the other end of the limiting bracket is tangential to the inner wall of the mounting base.
[0017] By adopting the above technical solution, one end of the limiting bracket is fixed to the support base, and the other end is tangent to the inner wall of the mounting base. This fixes the position of the cleaning component within the heat exchange plate cavity, facilitating the opening of the sealing cover and removal of the cleaning component from the protective shell for maintenance when needed. When the pressure difference increases, the liquid inside the protective shell enters the cleaning main pipe through the water inlet port, and is then transported by the cleaning main pipe to the cleaning brush. At this time, the drive motor starts, driving the rotating shaft and the cleaning main pipe to rotate, thereby achieving an effective scrubbing effect on the inner wall of the heat exchange plate.
[0018] As a preferred embodiment, the lower part of one end of the rotating shaft relative to the main cleaning pipe is configured as a hollow pipe, and spray branch pipes connected to it are evenly arranged on the outer periphery of the rotating shaft.
[0019] By adopting the above technical solution, the spray branch pipe facilitates the spraying of cleaning fluid into the main cleaning pipe, thereby facilitating the rinsing of deposits on the inner wall of the heat exchange plate during the cleaning process. The rinsed deposits automatically enter the drain pipe due to their own weight, thus thoroughly removing dirt from the surface of the heat exchange plate and improving the working efficiency and cleaning quality of the cleaning brush.
[0020] As a preferred embodiment, the cleaning brush includes a hollow cleaning frame, cleaning bristles disposed on one side of the cleaning frame relative to the inner wall of the heat exchange plate, a water inlet branch pipe connected to the other end of the cleaning frame, a connecting seat disposed at the connection between the water inlet branch pipe and the cleaning frame, a water inlet pipe slidably connected to the water inlet branch pipe, a limiting ring disposed on the outer periphery of the water inlet pipe, and an adjusting spring disposed between the limiting ring and the water inlet branch pipe. The water inlet pipe is connected to the main cleaning pipe, and a sealing bushing is provided at the connection between the water inlet pipe and the water inlet branch pipe.
[0021] By adopting the above technical solution, when deposits accumulate on the inner wall of the heat exchange plate, the adjusting spring, due to the force exerted by the cleaning brush bristles, drives the cleaning frame away from the inner wall of the heat exchange plate. This ensures that the cleaning brush remains tangential to the inner wall of the heat exchange plate, facilitating cleaning. Specifically, when deposits accumulate inside the heat exchange plate, the cleaning brush cleans through the hollow cleaning frame and the cleaning bristles on one side. The inlet branch pipe is connected to the inlet main pipe, and the inlet main pipe is equipped with an adjusting spring that cooperates with the limiting ring, ensuring that the position of the inlet main pipe within the inlet branch pipe is adjustable.
[0022] As a preferred embodiment, one end of the adjusting spring is fixedly connected to the end of the water inlet pipe away from the cleaning frame, and the other end of the adjusting spring is fixedly connected to the limiting retaining ring.
[0023] By adopting the above technical solution and adjusting the spring, the cleaning brush bristles can always maintain contact with the inner wall of the heat exchange plate, thereby effectively removing deposits on the inner wall and achieving efficient cleaning.
[0024] As a preferred embodiment, the system further includes a controller electrically connected to the signal output terminal of the pressure sensor, the signal output terminal of the controller being electrically connected to the signal input terminal of the drain valve, and the signal output terminal of the drain valve being electrically connected to the signal input terminal of the drive motor.
[0025] By adopting the above technical solution, the pressure sensor monitors the pressure difference between the inlet and outlet ports in real time. When the pressure difference increases, the drain valve opens, causing the drive motor to rotate the cleaning brush and physically scrub the inner wall of the heat exchange plate.
[0026] Compared with the prior art, the beneficial effects of this utility model are: This utility model;
[0027] Condensate enters the inner cavity of the protective shell through the inlet, exchanges heat through the heat exchange plate, and is discharged through the outlet. During long-term use, deposits will accumulate on the inner wall of the heat exchange plate. The pressure sensor detects the pressure difference between the inlet and outlet in real time. When the pressure difference increases, it indicates that the resistance caused by the deposits has increased. At this time, the drain valve opens, and the cleaning component uses the backwashing force to physically clean the inner wall of the heat exchange plate.
[0028] At the same time, the ultrasonic generator performs ultrasonic cleaning on the surface of the heat exchange plate and the protective shell from the outside. Finally, the wastewater after cleaning is discharged through the drain pipe, thereby realizing automatic, efficient and thorough cleaning of the heat exchange plate, ensuring that the heat exchange efficiency is not affected and effectively extending the service life of the equipment.

[0042] like Figures 1 to 5 As shown, a rapid evaporator cleaning device includes a protective housing 100 with its opening facing upwards, an inlet 11 disposed on one side of the protective housing 100, an outlet disposed on the other side of the protective housing 100, pressure sensors 2 disposed on the inlet 11 and the outlet respectively, a heat exchange plate 3 disposed in the inner cavity of the protective housing 100, a mounting base 4 fixedly disposed in the inner cavity of the protective housing 100 for mounting the heat exchange plate 3, a handle 31 disposed on the upper end face of the heat exchange plate 3, and a sealing cover plate 5 disposed on the upper end face of the protective housing 100.
[0043] Please refer to details. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The sealing cover 5 is detachably connected to the protective housing 100, and the cleaning mechanism is connected to the sealing cover 5. By designing the sealing cover 5 and the protective housing 100 to be detachably connected, and connecting the cleaning mechanism to the sealing cover 5, the sealing cover 5 can be moved easily, so that the cleaning mechanism can be removed from the protective housing 100 for maintenance, ensuring that the cleaning components can efficiently complete the cleaning task and maintain a good cleaning effect.
[0044] Please refer to details. Figure 1 and Figure 2The heat exchange plate 3 and the inner cavity of the protective shell 100 are set with the same curvature, and the heat exchange plate 3 and the mounting base 4 are connected by a snap-fit structure. The heat exchange plate 3 and the inner cavity of the protective shell 100 are set with the same curvature, and are connected to the mounting base 4 by a snap-fit structure, which makes the heat exchange plate 3 easy to disassemble and assemble, thereby facilitating its maintenance, ensuring that it can effectively carry out heat exchange operations, and ensuring the normal operation of the entire system.
[0045] Please refer to details. Figure 2 , Figure 3 , Figure 4 and Figure 5 The invention comprises a cleaning component penetrating the sealing cover plate 5 and disposed within the inner cavity of the heat exchange plate 3, an ultrasonic generator disposed within the inner cavity of the protective housing 100, a drain pipe 62 disposed on the lower end face of the protective housing 100, and a drain valve 621 disposed on the drain pipe 62. In this invention, condensate enters the inner cavity of the protective housing 100 through the liquid inlet 11, exchanges heat through the heat exchange plate 3, and is discharged through the liquid outlet. During long-term use, deposits will accumulate on the inner wall of the heat exchange plate 3. The pressure sensor 2 detects the pressure difference between the liquid inlet 11 and the liquid outlet in real time. When the pressure difference increases, it indicates that the resistance caused by the deposits has increased. At this time, the drain valve 621 opens, and the cleaning component uses backwashing force to physically clean the inner wall of the heat exchange plate 3. At the same time, the ultrasonic generator performs ultrasonic cleaning on the surface of the heat exchange plate 3 and the protective housing 100 from the outside. Finally, the wastewater after cleaning is discharged through the drain pipe 62, thereby achieving automatic, efficient, and thorough cleaning of the heat exchange plate 3, ensuring that the heat exchange efficiency is not affected, and effectively extending the service life of the equipment.
[0046] For details, please refer to Figure 3 , Figure 4 and Figure 5 The system includes a rotating shaft 63 rotatably connected to the cleaning component and the sealing cover plate 5, a drive motor 8 fixedly connected to the sealing cover plate 5 and connected to the rotating shaft 63, a cleaning main pipe 61 connected to the other end of the rotating shaft 63, a water inlet port 611 located on the lower end face of the cleaning main pipe 61, a support base 612 located on the outer periphery of the water inlet port 611, a limiting bracket evenly distributed on the outer periphery of the support base 612 and between it and the mounting base 4, and a cleaning brush 7 located on the cleaning main pipe 61 and connected to it. When the pressure difference increases, the liquid in the protective shell 100 enters the cleaning main pipe 61 through the water inlet port 611, and the cleaning liquid in the cleaning main pipe 61 enters the cleaning brush 7 connected to it. The drive motor 8 starts, driving the rotating shaft 63 to rotate. When the rotating shaft 63 rotates, it drives the cleaning main pipe 61 to rotate, thereby causing the cleaning main pipe 61 to drive the cleaning brush 7 to scrub the inner wall of the heat exchange plate 3.
[0047] Please refer to details. Figure 4 and Figure 5A sealed bearing is provided at the connection between the support base 612 and the water inlet port 611. When the cleaning main pipe 61 rotates, the sealed bearing between the support base 612 and the water inlet port 611 ensures that the liquid can pass smoothly through the water inlet port 611 when the cleaning main pipe 61 rotates, and avoids the liquid from accumulating in the cleaning main pipe 61.
[0048] Please refer to details. Figure 5 One end of the limiting bracket is fixedly connected to the support base 612, and the other end of the limiting bracket is tangentially set to the inner wall of the mounting base 4. This fixes the cleaning component in the inner cavity of the heat exchange plate 3, facilitating the opening of the sealing cover 5 and removal of the cleaning component from the protective housing 100 for maintenance when needed. When the pressure difference increases, the liquid inside the protective housing 100 enters the cleaning main pipe 61 through the water inlet port 611, and is then transported by the cleaning main pipe 61 to the cleaning brush 7. At this time, the drive motor 8 starts, driving the rotating shaft 63 and the cleaning main pipe 61 to rotate, thereby achieving an effective scrubbing effect on the inner wall of the heat exchange plate 3.
[0049] Please refer to details. Figure 3 , Figure 4 and Figure 5 To ensure the cleaning effect of the cleaning brush 7, the lower part of the rotating shaft 63 relative to the main cleaning pipe 61 is set as a hollow pipe, and spray branch pipes 631 connected to it are evenly arranged on the outer periphery of the rotating shaft 63. The spray branch pipes 631 facilitate the spraying of cleaning liquid into the main cleaning pipe 61, thereby facilitating the rinsing of the deposits on the inner wall of the heat exchange plate 3 during the cleaning process. The washed deposits automatically enter the drain pipe 62 due to their own weight, thereby thoroughly removing the dirt on the surface of the heat exchange plate 3 and improving the working efficiency and cleaning quality of the cleaning brush 7.
[0050] Please refer to details. Figure 3 and Figure 4The cleaning brush 7 includes a hollow cleaning frame 71, cleaning brush bristles 7 disposed on one side of the cleaning frame 71 relative to the inner wall of the heat exchange plate 3, a water inlet branch pipe 721 connected to the other end of the cleaning frame 71, a connecting seat 72 disposed at the connection between the water inlet branch pipe 721 and the cleaning frame 71, a water inlet pipe 73 slidably connected to the water inlet branch pipe 721, a limiting ring 731 disposed on the outer periphery of the water inlet pipe 73, and an adjusting spring 74 disposed between the limiting ring 731 and the water inlet branch pipe 721. The water inlet pipe 73 is connected to the main cleaning pipe 61, and a sealing bushing is provided at the connection between the water inlet pipe 73 and the water inlet branch pipe 721. When deposits are deposited on the inner wall of the heat exchange plate 3, the adjusting spring 74, due to the force exerted by the cleaning brush bristles, drives the cleaning frame 71 to move away from the inner wall of the heat exchange plate 3, thereby ensuring that the cleaning brush 7 is always tangent to the inner wall of the heat exchange plate 3, facilitating the cleaning brush 7 to clean the inner wall. The specific working principle is as follows: When deposits accumulate inside the heat exchange plate 3, the cleaning brush 7 cleans the interior through the hollow cleaning frame 71 and the cleaning brush bristles on one side. The water inlet branch pipe 721 is connected to the water inlet main pipe 73. The water inlet main pipe 73 is equipped with an adjusting spring 74 that cooperates with the limiting ring 731, ensuring that the position of the water inlet main pipe 73 within the water inlet branch pipe 721 is adjustable. Under normal operating conditions, the water inlet main pipe 73 is connected to the main cleaning pipe 61, and the connection is sealed by a sealing bushing. When the cleaning process begins, water flow transmits pressure through the water inlet branch pipe 721 to the water inlet main pipe 73. Due to the force of the cleaning brush bristles, the cleaning frame 71 moves within the water inlet main pipe 73. Through the action of the adjusting spring 74, the cleaning brush bristles maintain constant contact with the inner wall of the heat exchange plate 3, effectively removing deposits and achieving efficient cleaning.
[0051] One end of the adjusting spring 74 is fixedly connected to the end of the water inlet pipe 73 away from the cleaning frame 71, and the other end of the adjusting spring 74 is fixedly connected to the limiting ring 731. Through the action of the adjusting spring 74, the bristles of the cleaning brush 7 can always maintain contact with the inner wall of the heat exchange plate 3, thereby effectively removing the deposits on the inner wall and achieving efficient cleaning.
[0052] Additionally, a controller is electrically connected to the signal output terminal of the pressure sensor 2. The signal output terminal of the controller is electrically connected to the signal input terminal of the drain valve 621. The signal output terminal of the drain valve 621 is electrically connected to the signal input terminal of the drive motor 8. The pressure sensor 2 monitors the pressure difference between the inlet port 611 and the outlet port in real time. When the pressure difference increases, the drain valve 621 opens, causing the drive motor 8 to drive the cleaning brush 7 to rotate and physically scrub the inner wall of the heat exchange plate 3.
[0053] In this embodiment, during use, condensate enters the inner cavity of the protective housing 100 through the inlet 11, undergoes heat exchange through the heat exchange plate 3, and is discharged through the outlet. During prolonged use, deposits accumulate on the inner wall of the heat exchange plate 3. The pressure sensor 2 monitors the pressure difference between the inlet 11 and the outlet in real time. When the pressure difference increases, it indicates increased resistance due to the deposits. At this time, the drain valve 621 opens. When deposits accumulate inside the heat exchange plate 3, the cleaning brush 7 cleans it using the hollow cleaning frame 71 and the cleaning brush bristles on one side. The water inlet branch pipe 721 is connected to the water inlet main pipe 73. The water inlet main pipe 73 is equipped with an adjusting spring 74 that cooperates with the limiting retaining ring 731, ensuring that the position of the water inlet main pipe 73 within the water inlet branch pipe 721 can be adjusted. Under normal operating conditions, the water inlet main pipe 73 is connected to the main cleaning pipe 61, and the sealing bushing ensures the seal at the connection. When the cleaning process begins, the water flow transmits pressure to the inlet water pipe 73 through the inlet branch pipe 721. Due to the force of the cleaning brush bristles 7, the cleaning frame 71 moves in the inlet water pipe 73. Through the action of the adjusting spring 74, the cleaning brush bristles 7 can always maintain contact with the inner wall of the heat exchange plate 3. The spray branch pipe 631 facilitates the spraying of the cleaning liquid entering the cleaning main pipe 61, thereby facilitating the rinsing of the deposits on the inner wall of the heat exchange plate 3 during the cleaning process. The rinsed deposits automatically enter the drain pipe 62 due to their own weight, thereby thoroughly removing the dirt on the surface of the heat exchange plate 3 and effectively removing the deposits on the inner wall, achieving efficient cleaning. At the same time, the ultrasonic generator performs ultrasonic cleaning on the surface of the heat exchange plate 3 and the protective shell 100 from the outside. Finally, the wastewater after cleaning is discharged through the drain pipe 62, thereby achieving automatic, efficient and thorough cleaning of the heat exchange plate 3, ensuring that the heat exchange efficiency is not affected and effectively extending the service life of the equipment.
