Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to an integrated device for cleaning and air-cooled drying of vehicle-mounted plate-fin heat exchangers. Background Technology

[0002] Due to various reasons, plate-fin heat exchangers can accumulate fouling such as coke, oil, scale, deposits, and corrosion products. This fouling can easily lead to equipment and pipeline failures, increased energy and material consumption, and other adverse effects. Therefore, it is necessary to clean plate-fin heat exchangers.

[0003] Existing plate-fin heat exchanger cleaning devices typically employ chemical cleaning and high-pressure water jet cleaning. The plate-fin heat exchanger is placed in an immersion tank, into which chemical agents such as descaling agents, surface strippers, corrosion inhibitors, and passivating coating agents are added. The plate-fin heat exchanger is then sprayed with water for cleaning. However, existing devices struggle to automatically flip the plate-fin heat exchanger during the cleaning process, increasing manpower consumption and reducing cleaning efficiency. Therefore, this invention proposes an integrated vehicle-mounted plate-fin heat exchanger cleaning and air-cooled drying device to solve these problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes an integrated vehicle-mounted plate-fin heat exchanger cleaning and air-cooled drying device. This solves the problem in existing technologies where it is difficult to automatically flip the plate-fin heat exchanger during the cleaning process, which increases manpower consumption and reduces cleaning efficiency.

[0005] To achieve the purpose of this utility model, the following technical solution is adopted: an integrated cleaning and air-cooled drying device for vehicle-mounted plate-fin heat exchangers, including a cleaning tank, a first frame, and a second frame. The first frame is fixedly connected to the left side of the cleaning tank, and a drying mechanism is provided on the top of the first frame. The second frame is fixedly connected to the right side of the cleaning tank, and a cleaning mechanism is provided on the top of the second frame. A water outlet valve is connected to the top of the right side of the cleaning tank, and a water inlet valve is connected to the bottom of the right side of the cleaning tank. A filter screen is fixedly connected to the top of the cleaning tank. A driving mechanism is provided on the top of the cleaning tank, and a fixed frame is installed on the driving mechanism. A movable frame is rotatably connected inside the fixed frame through a rotating shaft. A limiting component is provided between the fixed frame and the movable frame. A partition is provided inside the cleaning tank.

[0006] A further improvement is that the limiting component includes a support frame, a pin, a pivot, a rotating knob, and a spring. The support frame is fixedly connected to one side of the fixed frame, and the pin is slidably connected inside the support frame. One end of the pin is hinged to a rotating knob via a pivot, and a spring is sleeved on one end of the pin.

[0007] A further improvement is that: the movable frame has symmetrical fixing holes on both sides, one end of the pin is inserted into the fixing hole, and the movable frame has symmetrical rounded corners on both sides.

[0008] A further improvement is that: the movable frame is provided with symmetrical sliding grooves on both sides, and a clamping block is slidably connected inside the sliding groove; threaded rods are symmetrically threaded on both sides of the movable frame, and one end of the threaded rod is rotatably connected to one side of the clamping block.

[0009] A further improvement is made in that: the driving mechanism includes a guide plate, a movable plate, a lead screw, and a motor; a guide plate is fixedly connected to one side of the top of the cleaning tank; a movable plate is slidably connected to the outer side of the guide plate; the top of the movable plate is fixedly connected to the bottom of the fixed frame; a lead screw is rotatably connected to the other side of the top of the cleaning tank; one end of the lead screw passes through the interior of the movable plate and is threadedly connected to it; a motor is fixedly installed on the left side of the cleaning tank; the output end of the motor is fixedly connected to the left end of the lead screw; a baffle is fixedly connected above the lead screw and the guide plate, and the positions of the baffle and the movable plate are offset from each other.

[0010] A further improvement is made in that: the cleaning mechanism includes a spray plate, a water pipe, a water pump and a filter; the spray plate is fixedly installed on the top of the second frame; the water pump is fixedly installed on one side of the second frame; the output end of the water pump is connected to the top of the spray plate through a water pipe; the input end of the water pump is connected to the bottom of the cleaning tank through a water pipe; and a filter is provided at the connection between the water pipe and the cleaning tank.

[0011] A further improvement is that the air-drying mechanism includes an air distribution plate, a fan, and a ventilation plate. The air distribution plate is fixedly installed on the top of the first frame, and the fan is fixedly installed on one side of the first frame. The output end of the fan is connected to the top of the air distribution plate through the ventilation plate.

[0012] The beneficial effects of this utility model are as follows: When the rotating pin is in a vertical state, the pin can pull the pin to move outward from the support frame, and remove the pin from the fixing hole on one side of the movable frame, releasing the limit between the fixed frame and the movable frame. At this time, the movable frame can rotate inside the fixed frame with the rotation axis center to flip the vehicle-mounted plate-fin heat exchanger. At this time, the spring in the compressed state is further compressed, pushing the rotating knob to reset. The elastic force generated by the spring drives the pin to insert into the corresponding fixing hole, and re-locks the position of the fixed frame and the movable frame. This solves the problem in the prior art that it is difficult to automatically flip the plate-fin heat exchanger during the cleaning process, which increases manpower consumption and reduces cleaning efficiency.

[0021] according to Figure 1-6As shown, this embodiment proposes an integrated cleaning and air-cooled drying device for vehicle-mounted plate-fin heat exchangers, including a cleaning tank 1, a first frame 2, and a second frame 3. The first frame 2 is fixedly connected to the left side of the cleaning tank 1, and a drying mechanism is provided on the top of the first frame 2. The second frame 3 is fixedly connected to the right side of the cleaning tank 1, and a cleaning mechanism is provided on the top of the second frame 3. A water outlet valve 20 is connected to the top of the right side of the cleaning tank 1, and a water inlet valve 21 is connected to the bottom of the right side of the cleaning tank 1. A filter screen 4 is fixedly connected to the top of the cleaning tank 1. A driving mechanism is provided on the top of the cleaning tank 1, and a fixed frame 7 is mounted on the driving mechanism. A movable frame 9 is rotatably connected inside the fixed frame 7 via a rotating shaft 8. A limiting component 11 is provided between the fixed frame 7 and the movable frame 9. A partition is provided inside the cleaning tank 1, and the bottom of the cleaning tank 1 is drained through the water inlet valve 21. Water is injected into the tank, and the vehicle-mounted plate-fin heat exchanger is fixed on the movable frame 9. The vehicle-mounted plate-fin heat exchanger is driven by the drive mechanism to pass under the cleaning mechanism and the drying mechanism in sequence. The cleaning mechanism draws water from the bottom of the cleaning tank 1 to clean one side of the vehicle-mounted plate-fin heat exchanger, and the drying mechanism dries one side of the vehicle-mounted plate-fin heat exchanger. The limiting component 11 is released from the restriction between the fixed frame 7 and the movable frame 9. The movable frame 9 rotates inside the fixed frame 7 through the rotating shaft 8 to flip the vehicle-mounted plate-fin heat exchanger. Then, the position of the fixed frame 7 and the movable frame 9 is locked by the limiting component 11. The above steps are repeated to clean and dry the other side of the vehicle-mounted plate-fin heat exchanger. The partition divides the interior of the cleaning tank 1 into two parts. After cleaning, the sewage flows through the filter screen 4 to the top of the partition and is discharged to the outside of the cleaning tank 1 through the outlet valve 20.

[0022] The limiting component 11 includes a support frame 12, a pin 13, a pin 14, a rotating knob 15, and a spring 16. The support frame 12 is fixedly connected to one side of the fixed frame 7. The pin 13 is slidably connected inside the support frame 12. One end of the pin 13 is hinged to the rotating knob 15 via the pin 14. The spring 16 is sleeved on one end of the pin 13. Fixed holes 10 are symmetrically provided on both sides of the movable frame 9. One end of the pin 13 is inserted into the fixed hole 10. Rounded corners are symmetrically provided on both sides of the movable frame 9. The rotating pin 14 is vertical. In the straight state, the pin 14 can pull the pin 13 to move outward of the support frame 12, and remove the pin 13 from the fixing hole 10 on one side of the movable frame 9, releasing the limit between the fixed frame 7 and the movable frame 9. At this time, the movable frame 9 can rotate inside the fixed frame 7 with the center of the rotation shaft 8 to flip the vehicle plate fin heat exchanger. At this time, the spring 16, which is in a compressed state, is further compressed, pushing the rotary knob 15 to reset. The elastic force generated by the spring 16 drives the pin 13 to insert into the corresponding fixing hole 10, and re-lock the position of the fixed frame 7 and the movable frame 9.

[0023] The movable frame 9 has symmetrically arranged sliding grooves 17 on both sides. Clamping blocks 18 are slidably connected inside the sliding grooves 17. Threaded rods 19 are symmetrically threaded on both sides of the movable frame 9. One end of the threaded rod 19 is rotatably connected to one side of the clamping block 18. After the vehicle-mounted plate-fin heat exchanger is placed inside the movable frame 9, both threaded rods 19 are turned in the same direction. The threaded rods 19 can drive the clamping blocks 18 to gradually approach the vehicle-mounted plate-fin heat exchanger. The clamping blocks 18 cooperate with the movable frame 9 to clamp the two sides of the vehicle-mounted plate-fin heat exchanger, thereby fixing the vehicle-mounted plate-fin heat exchanger inside the movable frame 9. After cleaning, both threaded rods 19 are turned in opposite directions to drive the clamping blocks 18 away from the vehicle-mounted plate-fin heat exchanger, allowing the vehicle-mounted plate-fin heat exchanger to be removed from inside the movable frame 9.

[0024] The driving mechanism includes a guide plate 5, a movable plate 6, a lead screw 22, and a motor 23. The guide plate 5 is fixedly connected to one side of the top of the cleaning tank 1. The movable plate 6 is slidably connected to the outer side of the guide plate 5. The top of the movable plate 6 is fixedly connected to the bottom of the fixed frame 7. The lead screw 22 is rotatably connected to the other side of the top of the cleaning tank 1. One end of the lead screw 22 passes through the interior of the movable plate 6 and is threadedly connected to it. The motor 23 is fixedly installed on the left side of the cleaning tank 1. The output end of the motor 23 is fixedly connected to the left end of the lead screw 22. A baffle 24 is fixedly connected above the guide plate 5 to the lead screw 22, and the baffle 24 is connected to the movable plate... The positions of 6 are staggered. The lead screw 22 is threadedly engaged with the moving plate 6, and the guide plate 5 restricts the movement trajectory of the moving plate 6. The motor 23 can drive the lead screw 22 to rotate on one side of the top of the cleaning tank 1. When the lead screw 22 rotates forward and backward, it can drive the moving plate 6 to move back and forth in a straight line along the guide plate 5. The fixed frame 7 is connected to the moving plate 6 as a whole, and is used to drive the fixed frame 7 to move back and forth in a straight line. The vehicle-mounted plate-fin heat exchanger is fixed inside the fixed frame 7 through the movable frame 9. The fixed frame 7 can drive the vehicle-mounted plate-fin heat exchanger to move back and forth in a straight line at the top of the cleaning tank 1, so that the vehicle-mounted plate-fin heat exchanger is cleaned and dried in sequence below the cleaning mechanism and the drying mechanism.

The output end of the water pump 27 is connected to the top of the spray plate 25 through the water pipe 26, and the input end of the water pump 27 is connected to the bottom of the cleaning tank 1 through the water pipe 26. A filter 28 is provided at the connection between the water pipe 26 and the cleaning tank 1. The water pump 27 can draw clean water from the bottom of the cleaning tank 1 through the water pipe 26 to the interior of the spray plate 25. The spray plate 25 sprays clean water onto the vehicle-mounted plate-fin heat exchanger inside the fixed frame 7 for automatic rinsing of the vehicle-mounted plate-fin heat exchanger. The filter 28 can purify the water at the bottom of the cleaning tank 1 to ensure the purity of the clean water.

The air distribution plate 29 is fixedly installed on the top of the first frame 2, and the fan 30 is fixedly installed on one side of the first frame 2. The output end of the fan 30 is connected to the top of the air distribution plate 29 through the ventilation plate 31. The ventilation plate 31 can draw in outside air and deliver it to the interior of the air distribution plate 29. The air distribution plate 29 blows the air onto the vehicle-mounted plate-fin heat exchanger to quickly dry the moisture on the vehicle-mounted plate-fin heat exchanger, thereby saving cleaning time and speeding up the cleaning efficiency.

[0027] The device fills the bottom of the cleaning tank 1 with water through the inlet valve 21, fixes the vehicle-mounted plate-fin heat exchanger on the movable frame 9, and drives the vehicle-mounted plate-fin heat exchanger to pass under the cleaning mechanism and the drying mechanism in sequence through the drive mechanism. The cleaning mechanism draws water from the bottom of the cleaning tank 1 to clean one side of the vehicle-mounted plate-fin heat exchanger, and the drying mechanism dries one side of the vehicle-mounted plate-fin heat exchanger. The limiting component 11 is released from the restriction between the fixed frame 7 and the movable frame 9, and the movable frame 9 rotates inside the fixed frame 7 through the rotating shaft 8 to flip the vehicle-mounted plate-fin heat exchanger.
