[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-5 , the present invention provides a technical solution: a dust-proof net assembly for a split welded plate-type circulating water flow channel heat exchanger, including a heat exchanger main body 1, a dust-proof net main body 2 fixedly connected to the outside of the heat exchanger main body 1, mesh holes 3 provided inside the dust-proof net main body 2, a reciprocating mechanism 4 provided between the dust-proof net main body 2 and the heat exchanger main body 1, and an elastic mechanism 5 provided on one side of the reciprocating mechanism 4;

[0022] The reciprocating mechanism 4 includes a rotating disk 401 rotatably connected to the inner wall on one side of the dust-proof net main body 2. A rotating blade 402 is fixedly connected to the outside of the rotating disk 401. A chute 403 is provided inside the rotating disk 401. A slider 404 is provided inside the chute 403. One end of the chute 403 away from the second connecting plate 406 is larger than the end of the chute 403 close to the second connecting plate 406. The outer side surface of the slider 404 fits with the inner side surface of the chute 403, so that the slider 404 will not shake when moving inside the chute 403. A first connecting plate 405 is fixedly connected to one side of the slider 404. The thickness of the rotating disk 401 is smaller than the length of the slider 404, so that the slider 404 can always control the rotating disk 401. The end of the first connecting plate 405 away from the rotating disk 401 is fixedly connected to a second connecting plate 406. A guiding groove 407 communicates with the inner wall on the other side of the dust-proof net main body 2. A guiding rod 408 is provided inside the guiding groove 407. The guiding rod 408 is fixedly connected to the second connecting plate 406. The central axis of the chute 403 is perpendicular to the center of the rotating disk 401. The guiding groove 407 is composed of an arc opening inward and an arc opening outward. And multiple groups of the arc opening inward and the arc opening outward are provided, and multiple groups of the arc opening inward and the arc opening outward are communicated with each other, so that when the guiding rod 408 moves inside the guiding groove 407, it can drive the first connecting plate 405 and the slider 404 to move vertically outward along the central axis of the chute 403.

[0023] The elastic mechanism 5 includes a first support plate 501 fixedly connected to the outside of the first connecting plate 405. A first groove 502 is provided inside the first support plate 501. An elastic rubber pad 503 is provided inside the first groove 502. One end of the elastic rubber pad 503 is fixedly connected to a second support plate 504. A fourth support plate 505 is rotatably connected to the inside of the second support plate 504. The other end of the fourth support plate 505 is fixedly connected to a third connecting plate 506. The other end of the third connecting plate 506 is fixedly connected to a ejector rod 507. A torsion spring 508 is fixedly connected between the second support plate 504 and the fourth support plate 505. The outer structure of the second support plate 504 is a cuboid, and the outer side surface of the second support plate 504 fits with the outer side surface of the first groove 502, so that the second support plate 504 will not rotate or turn when moving inside the first groove 502.

[0024] When there is water flow entering the inner side of the dust-proof net main body 2 from the mesh holes 3, it pushes the rotating blades 402 and the rotating disc 401 to rotate, causing the sliding grooves 403 and the slider 404 and the first connecting plate 405 to rotate, and causing the second connecting plate 406 and the guide rod 408 to rotate. Since the guide groove 407 is composed of an arc with an opening inward and an arc with an opening outward, and multiple groups of arcs with an opening inward and an arc with an opening outward are arranged, and multiple groups of arcs with an opening inward and an arc with an opening outward are interconnected, the first connecting plate 405, the second connecting plate 406 and the slider 404 perform reciprocating motions outward, driving the first support plate 501, the second support plate 504, the fourth support plate 505, the third connecting plate 506 and the ejector rod 507 to perform reciprocating motions. When the ejector rod 507 moves outward and does not directly move to the inner side of the mesh hole 3 at this time, the ejector rod 507, the third connecting plate 506, the fourth support plate 505 and the second support plate 504 are compressed. When the ejector rod 507 coincides with the mesh hole 3, the ejector rod 507 moves to the inner side of the mesh hole 3 to clean the impurities inside the mesh hole 3. At this time, the ejector rod 507 cannot directly move out of the inner side of the mesh hole 3, enabling the fourth support plate 505 to rotate inside the second support plate 504, causing the torsion spring 508 to store energy. When the guide rod 408 moves back to the apex in the guide groove 407, the ejector rod 507 can be completely moved out of the inner side of the mesh hole 3, and the elastic rubber pad 503 and the torsion spring 508 are both reset, preparing for the next cleaning. The entire cleaning process does not require the participation of staff, making the cleaning process simple.
