[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid, also known as heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used. Various types of domestic heat exchangers have been put into actual production and application and achieved good results.

[0003] At present, the existing heat exchangers are usually energy-saving heat exchangers. However, after a long period of use, impurities in the fluid are easily attached to the inside of the heat exchanger to form a large amount of scale, which affects the heat exchange work.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-Figure 6 , an anti-scaling energy-saving heat exchanger, comprising a heat exchanger shell 1, both end walls of the heat exchanger shell 1 are provided with heads, the heat exchanger shell 1 is divided into two chambers through a partition plate 2 for passing cold and hot fluids respectively, the heat insulation plate 2 is made of a material with good thermal conductivity, so that the cold and hot fluids in the two chambers can exchange heat, and a cleaning component is provided in both chambers, the cleaning component comprises a limit rod 3 fixedly connected to the head on one side of the heat exchanger shell 1, the side wall sliding sleeve of the limit rod 3 is provided with a cleaning plate 4, and the limit rod 3 can clean The plate 4 plays a limiting role, so that the cleaning plate 4 can move along the heat exchanger shell 1. The side wall of the cleaning plate 4 is provided with cleaning bristles 5 that abut against the inner wall of the heat exchanger shell 1 and the side wall of the partition 2. The front and rear bristles of the cleaning bristles 5 are staggered, which can fully perform the cleaning work and reduce dead angles. The cleaning plate 4 moves in the heat exchanger shell 1 and can clean the inner wall of the heat exchanger shell 1 and the side wall of the partition 2 to prevent scaling. The cleaning component, the driving component and the side wall of the partition are coated with a protective coating to avoid rust.

[0024] The two cleaning components are driven to move by a driving component installed on the heat exchanger housing 1. The driving component includes two threaded rods 6 that are sealed and rotatably connected to the head on one side. The two threaded rods 6 are respectively threaded through the corresponding cleaning plates 4. The threaded rods 6 rotate to move the cleaning plates 4 under the action of their thread engagement. The two threaded rods 6 are connected by a transmission belt 7 so that the two threaded rods 6 can rotate synchronously. A T-shaped plate 8 is fixedly connected to the side wall of the head. A servo motor 9 that drives one of the threaded rods 6 to rotate is installed on the side wall of the T-shaped plate 8.

[0025] The heat exchanger housing 1 is penetrated with a water inlet pipe 10 and a water outlet pipe 16 which are respectively connected to the two chambers. The two water inlet pipes 10 are connected with a filter pipe 11. A filter assembly is arranged in the filter pipe 11. The filter assembly includes a plurality of support blocks fixedly connected to the inner wall of the filter pipe 11. A filter plate 12 which is slidably connected to the filter pipe 11 and abuts against the support block is slidably connected to the filter pipe 11. The filter plate 12 is detachably fixed to the support block. The filter plate 12 is fixed to the support block by screws, so that it is easy to remove it for cleaning or replacement. A plurality of filter screens are penetrated with the filter plate 12. The filter screens can filter the fluid entering the heat exchanger housing 1 through the water inlet pipe 10, thereby reducing the impurities in the fluid from being attached to the filter. The inner wall of the heat exchanger shell 1 is used to cause scaling. The side wall of the filter plate 12 is rotatably connected to a rotating rod 13. The side wall of the rotating rod 13 is fixedly connected to a cleaning brush 14 that abuts against the filter plate 12. The cleaning brush 14 can rotate to clean the filter plate 12 to avoid clogging of the filter screen. The side wall of the rotating rod 13 is fixedly connected to an impeller 15 with inclined blades. When the fluid enters the filter tube 11, due to the inclined setting of the impeller 15, the fluid will impact the impeller 15 to rotate, thereby driving the rotating rod 13 to rotate. The ends of the filter tube 11 and the water outlet pipe 16 are both provided with external threads. Through the setting of the external threads, the liquid guide tube can be connected to the filter tube 11 and the water outlet pipe 16.

[0026] The functional principle of the utility model can be explained through the following operation modes:

[0027] In the utility model, when the anti-scaling energy-saving heat exchanger is working, the cold and hot fluids enter the two chambers through the two filter tubes 11 and the water inlet pipe 10 respectively and are discharged through the corresponding water outlet pipe 16, the cold and hot fluids are heat exchanged through the partition plate 2, the cleaning plate 4 blocks the fluid, reduces the fluid flow rate, and the fluid flows through the gap between the cleaning bristles 5, thereby increasing the heat exchange time;

[0028] When the fluid enters the filter tube 11, the filter screen can filter the fluid entering the heat exchanger housing 1 through the water inlet pipe 10, thereby reducing the impurities in the fluid from adhering to the inner wall of the heat exchanger housing 1 and the side wall of the partition plate 2 to cause scaling. Since the impeller 15 is arranged obliquely, the fluid will impact the impeller 15 to make it rotate, thereby driving the rotating rod 13 to rotate, so that the cleaning brush 14 rotates to clean the filter plate 12, thereby avoiding clogging of the filter screen.

[0029] The servo motor 9 drives one of the threaded rods 6 to rotate. Under the connection of the transmission belt 7, the two threaded rods 6 rotate synchronously, so that the cleaning plate 4 moves back and forth along the heat exchanger shell 1, and the cleaning bristles 5 clean the inner wall of the heat exchanger shell 1 and the side wall of the partition 2, further preventing scaling.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
