Description

Technical Field

[0001] This utility model relates to the field of heat exchanger cleaning technology, and in particular to an automatic heat exchanger cleaning and drying device. Background Technology

[0002] Plate heat exchangers typically consist of multiple corrugated plates. The stacking of these plates creates thin rectangular channels between adjacent plates, facilitating heat exchange. However, the corrugated shape makes it prone to fouling, which can impede fluid flow and reduce heat exchange efficiency.

[0003] To improve heat exchange efficiency, the corrugated plates need to be cleaned. The corrugated shape is complex, typically requiring manual cleaning, which is inefficient. Furthermore, the corrugated plates are heavy, and the cleaning process is dangerous. In addition, drying the plates after cleaning further increases labor costs, necessitating improvements. Utility Model Content

[0004] The purpose of this invention is to provide an automatic cleaning and drying device for heat exchangers, which can automatically clean and dry heat exchangers, improving ease of operation and efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution: An automatic cleaning and drying device for heat exchangers includes: a cleaning tank, a motor, a floating plate, a hanging rod, and a suspension assembly. The floating plate is vertically mounted above the cleaning tank. The motor is vertically mounted on the floating plate. The hanging rod is mounted at the bottom of the motor's shaft and extends downward. The suspension assembly is arranged in a circular array on the hanging rod. The suspension assembly includes a cantilever, a crossbeam, a hanging rod, and a stop pin. The cantilever is spaced vertically on the hanging rod and extends radially along the hanging rod. The crossbeam is horizontally mounted at the end of the cantilever. The hanging rod is spaced along the length of the crossbeam on its front side and is parallel to the cantilever. The stop pin is vertically mounted at the top of the hanging rod.

[0006] The corrugated plate is provided with through holes at intervals on the top and bottom. The corrugated plate is suspended on the hanging rod through the through holes and is limited by the stop pin. The diameter of the through holes is larger than the diameter of the hanging rod.

[0007] The cantilever is perpendicularly connected to the midpoint of the crossbeam.

[0008] The cleaning tank has wing plates on both sides of its top, and guide rods that extend upward through the floating plate are provided on the wing plates.

[0009] The floating plate is provided with a guide sleeve corresponding to the guide rod.

[0010] The wing plate is equipped with a hydraulic cylinder that drives the floating plate to rise and fall.

[0011] The cleaning tank is equipped with a liquid inlet pipe on one side.

[0012] The bottom of the cleaning tank is equipped with a drain pipe.

[0013] The beneficial effects of this utility model are as follows: An automatic cleaning and drying device for heat exchangers, in which the corrugated plate is suspended on the hanging rod through the through hole and limited by the stop pin, ensuring high safety. The floating plate drives the hanging rod to descend, allowing the corrugated plate to be immersed in the cleaning liquid below for rotational cleaning, which is highly efficient. After cleaning, the corrugated plate first rises a short distance with the floating plate and is removed from the cleaning liquid, while still in the cleaning tank. The rotation of the hanging rod drives the rotation of the corrugated plate, shaking off the surface water and quickly drying it. Finally, the floating plate rises back to its original position, allowing the corrugated plate to be disassembled. The operation is simple. Attached Figure Description

Detailed Implementation

[0015] The following is combined with Figures 1-4 The technical solution of this utility model will be further illustrated through specific embodiments.

[0016] like Figure 1 The heat exchanger automatic cleaning and drying device shown is used for automatic cleaning of the corrugated plate 6 in the heat exchanger. It includes: a cleaning tank 1, a motor 10, a floating plate 9, a hanging rod 2, and a suspension assembly. The floating plate 9 is movably mounted above the cleaning tank 1. The cleaning tank 1 has wing plates 8 on both sides of its top. The wing plates 8 are provided with guide rods 11 that extend upward through the floating plate 9. In this embodiment, the floating plate 9 is provided with guide sleeves 12 corresponding to the guide rods 11 to guide the floating plate 9 in raising and lowering.

[0017] A hydraulic cylinder 7 is provided on the wing plate 8 to drive the floating plate 9 to rise and fall, such as Figure 2 and Figure 3 As shown, the floating plate 9 is raised and lowered by the extension and retraction of the hydraulic cylinder 7. The extension and retraction of the hydraulic cylinder 7 can be controlled by a PLC, improving the level of automation.

[0018] The motor 10 is vertically mounted on the floating plate 9, and the suspension rod 2 is located at the bottom of the rotating shaft of the motor 10 and extends downwards. The motor 10 drives the rotation of the suspension rod 2. The rotation speed of the motor 10 can be controlled by a PLC.

[0019] The suspension components are arranged in a circular array on the hanger 2. Each suspension component can suspend one corrugated plate 6. In this embodiment, 2 to 4 suspension components are used, which can suspend 2 to 4 corrugated plates 6 at the same time and clean them synchronously, thereby improving production efficiency.

[0020] like Figure 1 and Figure 4 As shown, the suspension assembly includes a cantilever 3, a crossbeam 4, a hanging rod 5, and a stop pin 13. The cantilever 3 is spaced vertically on the hanging rod 2 and extends radially along the hanging rod 2. It can be welded and fixed, resulting in a robust structure. The crossbeam 4 is horizontally positioned at the end of the cantilever 3. In this embodiment, the cantilever 4 and the midpoint of the crossbeam 4 are perpendicularly connected and welded together to form a T-shaped structure.

[0021] The hanging rods 5 are spaced apart along the length of the crossbeam 4 on the front side of the crossbeam 4. In this embodiment, the hanging rods 5 are parallel to the cantilever 3. The corrugated plate 6 is provided with through holes 16 spaced apart vertically. Specifically, the corrugated plate 6 is provided with 2 through holes at the top and 2 through holes at the bottom, for a total of 4 through holes, which correspond one-to-one with the hanging rods 5 on the upper and lower crossbeams 4.

[0022] like Figure 4 As shown, the stop pin 13 is vertically positioned at the top of the hanging rod 5. In this embodiment, the corrugated plate 6 is suspended on the hanging rod 5 via the through hole 16, and is limited by the stop pin 13 to prevent the corrugated plate 6 from loosening during the rotation of the hanging rod 2. The diameter of the through hole 16 is larger than the diameter of the hanging rod 5, which facilitates the suspension of the corrugated plate 6 on the hanging rod 5 via the through hole 16, and allows it to move upwards during suspension to avoid the stop pin 13.

[0023] like Figure 3 As shown, an inlet pipe 14 is provided on one side of the cleaning tank 1 to facilitate the introduction of cleaning solution into the cleaning tank 1. A drain pipe 15 is provided at the bottom of the cleaning tank 1, and a valve can be installed on the drain pipe 15. After cleaning is completed, the valve is opened to discharge wastewater.

[0024] Operating steps: The floating plate 9 is used to drive the motor 10 and the boom 2 to descend, such as... Figure 1 As shown, the corrugated plate 6 is immersed in the cleaning solution in the cleaning tank 1 below for rotational cleaning, which is highly efficient. After cleaning, the corrugated plate 6 rises a short distance with the floating plate 9 and detaches from the cleaning solution, while still remaining in the cleaning tank 1. Figure 2As shown, the motor 10 drives the hanging rod 2 to rotate, which in turn drives the corrugated plate 6 to rotate, throwing off the surface moisture and quickly drying it. like Figure 3 As shown, finally, the floating plate 9 rises and resets, the corrugated plate 6 moves upward, and the top position is higher than the top of the cleaning tank 1, which facilitates the disassembly of the corrugated plate 6. Then, the corrugated plate to be cleaned is installed, and the operation is repeated.

For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
