Description

Technical Field

[0001] The utility model relates to the technical field of cleaning of plate - fin heat exchangers for agricultural machinery, in particular to a cleaning device for plate - fin heat exchangers for agricultural machinery. Background Technique

[0002] The cleaning of plate - fin heat exchangers for agricultural machinery is considered for multiple aspects such as improving heat transfer efficiency, extending equipment life, reducing production costs, and ensuring production safety and environmental health. After being used for a period of time, dirt and scale will accumulate on the surface and inside of the plate - fin heat exchanger. These dirt not only increase the thermal resistance but also reduce the heat conduction area, thus reducing the heat transfer efficiency. Therefore, a cleaning device for plate - fin heat exchangers for agricultural machinery is needed.

[0003] Patent Publication No. CN 220625032 U discloses an automatic cleaning device for plate - fin heat exchangers. The device clamps objects through clamping parts, uses a spraying component for flushing, and completes the rotation of objects through the connection of a second gear to achieve the effect of all - around flushing. However, in agricultural machinery, the dust and impurities in some heat exchangers have accumulated for a long time and are relatively hard. During the soaking process, the liquid only gradually penetrates in. The impurities on the surface will become loose under soaking, but it is difficult for the liquid to penetrate into the impurities in the central position, resulting in the impurities still being rigid on the object, thus increasing the cleaning time and cleaning difficulty. And the spraying component sprays in a horizontal manner, and the impurity liquid is easy to remain in the object. Therefore, a cleaning device for plate - fin heat exchangers for agricultural machinery is proposed. Summary of the Invention

[0025] Specifically, a plurality of limiting rods 6 are installed in the device body 1. One end of the limiting rod 6 is fixed on the top surface of the immersion tank 7, and the other end of the limiting rod 6 is erected on the inner wall of the device body 1. The lifting frame 25 is slidably connected to the outer surface of the limiting rod 6 to prevent shaking during the movement process.

[0026] Furthermore, the support frame 2 is in an "I" shape. A plurality of fixed bottom plates are welded and installed on the support frame 2 for convenient placement of objects. Clamping pieces 22 are movably connected to the top surfaces of the fixed bottom plates, and the cooperation between the two achieves a clamping effect. A threaded clamping rod 21 is rotatably connected to the top surface of one end of the clamping piece 22. The threaded clamping rod 21 is threadedly connected inside the support frame 2 to act on the adjustment of the position of the clamping piece 22. A heat exchanger is clamped between the clamping piece 22 and the fixed bottom plate. Shaking rods 23 are welded and installed on the outer side surfaces of both ends of the support frame 2. The shaking rods 23 are movably connected inside the support plate 24 to achieve the effect of the support frame 2 moving back and forth.

[0027] In this embodiment, a plurality of connecting rods 3 are horizontally installed on both sides of the support frame 2.

[0028] Working principle: Place the plate-fin heat exchanger into the support frame 2, rotate the threaded clamping rod 21 to clamp the object with the clamping piece 22. After clamping, control the first motor 9 to rotate. Under the meshing of the toothed pieces, the wire-releasing roller 5 will start to release the wire, and the lifting frame 25 will slide down along the limiting rod 6 until the connecting rod 3 is placed into the shaking frame 10. At this time, the object will be soaked in the soaking pool 7. Then control the second motor to rotate. The limit bottom frame 12 will be pushed back and forth, and the shaking frame 10 will move back and forth between the limit blocks 11, and the support frame 2 will also shake. Under the continuous shaking, the impurities soaked on the surface will loosen and disperse, and the soaking liquid can penetrate into the impurities more quickly, achieving the effect of quickly softening and loosening. After soaking, control the pull rope 8 to pull the support frame 2 upward. After pulling to the specified height, press down one end of the pressing clamping plate 26. At this time, the adjusting roller 27 can be rotated to keep the support frame 2 rotated by ninety degrees and in the vertical state, and then release the pressing clamping plate 26 to limit the adjusting roller 27 again. At this time, control the high-pressure flushing head 41 to flush, and the flushing liquid will directly flow into the soaking pool 7 for collection.
