Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a cold energy recovery heat exchanger with a surface condensate cleaning structure. Background Technique

[0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in many industrial productions such as chemical industry, petroleum, power, food and others. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators, reboilers, etc., and are widely used.

[0003] After the cold energy recovery heat exchanger in the prior art is used for a period of time, more condensates will be generated on its surface due to temperature difference. The long-term adhesion of condensates on the surface of the heat exchanger is likely to affect the normal use of the heat exchanger and lead to a decline in the use performance of the heat exchanger.

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1-3 and the present utility model provides a technical solution: A cold energy recovery heat exchanger with a surface condensate cleaning structure, including a housing 1 and a pressing plate 2. Symmetrically arranged scraping rings 3 are slidably connected to the housing 1. Symmetrically arranged chutes 4 are provided inside both of the two scraping rings 3. Springs 5 are fixedly connected inside multiple chutes 4. Telescopic rings 6 are slidably connected inside both of the two chutes 4. Symmetrically arranged vertical blocks 7 are fixedly connected to one side of both of the two scraping rings 3. Round rods 8 are fixedly connected to the opposite surfaces of multiple vertical blocks 7. A mounting bracket 9 is fixedly connected to one side of the housing 1. A guide rod 10 is fixedly connected between the top wall and the bottom wall of the mounting bracket 9. A limiting rod 11 is fixedly connected to one side of the mounting bracket 9. Symmetrically arranged support rods 12 are rotatably connected to the pressing plate 2. Linkage rods 13 are rotatably connected to both of the two support rods 12.

[0017] Further, the opposite ends of the telescopic ring 6 are both arc-shaped. The telescopic ring 6 is fixedly connected to the spring 5 at the corresponding positions inside the sliding groove 4. The spring 5 facilitates driving the telescopic ring 6 to move back to its original position.

[0018] Further, the specific shape of the mounting bracket 9 is C-shaped.

[0019] Further, one side of the scraping ring 3 is slidably connected to the guide rod 10, and the pressing plate 2 is slidably connected to the limiting rod 11. A pulling handle 14 is fixedly connected to one side of the pressing plate 2. The guide rod 10 facilitates guiding the movement of the scraping ring 3, and the limiting rod 11 facilitates guiding the movement of the pressing plate 2.

[0020] Further, one side of the linkage rod 13 is rotatably connected to the round rod 8. The linkage rod 13 facilitates driving the scraping ring 3 to move through the round rod 8.

[0021] Specifically, when using the present utility model, first, the pressing plate 2 is pushed towards the housing 1 through the pulling handle 14. The movement of the pressing plate 2 will drive the two support rods 12 to move together. The movement of the two support rods 12 will drive the linkage rod 13 to move together. At this time, the connection position between the linkage rod 13 and the support rod 12 moves towards the housing 1. When the connection position between the linkage rod 13 and the support rod 12 moves, it will also rotate. The vertically arranged linkage rods 13 will rotate in opposite directions. At this time, the round rods 8 connected to the linkage rod 13 will all be affected. The top round rods 8 will drive the top scraping ring 3 to move upward through the upright blocks 7, and the bottom round rods 8 will drive the bottom scraping ring 3 to move downward through the upright blocks 7. At this time, when the two scraping rings 3 move away from each other, they will both perform scraping work on the surface of the housing 1. When the scraping ring 3 drives the telescopic ring 6 to move to the connection port position on the housing 1, the arc-shaped positions of the telescopic ring 6 will abut against the connection port. Due to the abutment of the connection port, when the telescopic ring 6 follows the scraping ring 3 to move, it will retract into the sliding groove 4 due to the abutment of the connection port. The retraction of the telescopic ring 6 will compress and contract the spring 5. And the retraction of the telescopic ring 6 enables the scraping ring 3 to be unrestricted by the connection port on the housing 1. Just repeatedly push the pressing plate 2 to make the scraping ring 3 clean the surface of the housing 1 back and forth.
