Description

Technical Field

[0001] The utility model belongs to the field of heat exchange equipment, in particular to a heat exchange device for a heat exchange station. Background Art

[0002] The plate heat exchange station automatically and continuously converts the heat obtained from the primary network into domestic water and heating water required by users; that is, hot water (or steam) enters the plate heat exchanger from the primary side inlet of the unit for heat exchange and flows out from the primary side outlet of the machine; the secondary side return water passes through the filter to remove dirt, and then enters the plate heat exchanger through the secondary side circulating water pump for heat exchange, producing hot water of different temperatures such as heating, air conditioning, floor heating or domestic water to meet the needs of users; water-water direct mixing heat exchange group is one of them. The unit mainly consists of a mixing tank, a circulating pump, and a return water pressure pump. , temperature control device, control instrument and control cabinet and other parts; this unit has high heat exchange efficiency, low manufacturing cost and significant energy saving effect. Its main feature is that the primary high-temperature water and the low-temperature secondary water are directly mixed in the mixing tank for heat exchange, and the pressure of the primary water is fully utilized to minimize the power of the circulating water pump of the secondary water. However, when the existing heat exchange group is in use, the turbulence and diffusion of water are usually used to mix the primary high-temperature water and the low-temperature secondary water. However, the turbulence and diffusion of water alone cannot achieve a good mixing effect. Therefore, we designed a heat exchange station heat exchange device with good mixing effect.

The tank body 1, the rotating shaft 8, the box body 10 and the stirring rods 11 are coaxially arranged. The utility model has a simple structure and an ingenious design. The stirring rods 11 stir the primary high-temperature water and the low-temperature secondary water entering the box body 10, which can better mix them and achieve a better heat exchange effect. It can meet actual needs and is suitable for promotion. When using the present utility model, first connect the primary high-temperature water inlet pipe 4 and the low-temperature secondary water inlet pipe 5 and the outlet pipe 6 to the outside world, and the primary high-temperature water and the low-temperature secondary water enter the box body 10 through the corresponding pipes respectively. Start the motor 9, and the output shaft of the motor 9 drives the rotating shaft 8 to rotate, and the rotating shaft 8 drives the stirring rod 11 to rotate. The stirring rod 11 stirs the primary high-temperature water and the low-temperature secondary water in the box body 10 to fully mix them to achieve a better heat exchange effect. The fully mixed water escapes from the top of the box body 10 and enters the interior of the tank body 1. Open the valve 7, and the mixed water is discharged through the outlet pipe 6.

[0017] Specifically, as shown in the figure, one end of the primary high-temperature water inlet pipe 4, the low-temperature secondary water inlet pipe 5, and the outlet pipe 6 of this embodiment is provided with a first flange 20. During use, the first flange 20 can more conveniently connect the primary high-temperature water inlet pipe 4, the low-temperature secondary water inlet pipe 5, and the outlet pipe 6 to external pipes.

[0018] Specifically, as shown in the figure, the bottom of the rotating shaft 8 described in this embodiment is rotatably connected to the first annular plate 30 via a first one-way bearing. A plurality of first scrapers 31 are fixedly mounted on the outer periphery of the first annular plate 30, which are in sliding contact with the interior of the tank body 1. The first annular plate 30 and the first scrapers 31 are coaxially arranged with the rotating shaft 8. When the output shaft of the motor 9 drives the rotating shaft 8 to rotate in the forward direction, the rotating shaft 8 cannot drive the first annular plate 30 and the first scraper 31 to rotate via the first one-way bearing. When the output shaft of the motor 9 drives the rotating shaft 8 to rotate in the reverse direction, the rotating shaft 8 drives the first annular plate 30 and the first scraper 31 to rotate via the first one-way bearing, thereby scraping off impurities or scale attached to the inner wall of the tank body 1.

[0019] Furthermore, as shown in the figure, a vertical tube 41 is fixedly mounted at the bottom of the box body 10 in this embodiment via a plurality of connecting rods 40.

The rotating shaft 8, the vertical tube 41, and the spiral blade 42 are coaxially arranged. When the output shaft of the motor 9 drives the rotating shaft 8 to rotate, the rotating shaft 8 drives the spiral blade 42 to rotate. The spiral blade 42 transports the water at the bottom of the tank body 1 upward along the vertical tube 41, and finally re-enters the tank body 1 from the top of the vertical tube 41, thereby circulating the water in the tank body 1 and making the water inside the tank body 1 more evenly mixed.

[0020] Furthermore, as shown in the figure, the outer periphery of the cover 2 and the tank body 1 of this embodiment is respectively provided with a second flange 50, and the second flange 50 is provided with a bolt hole 51, and the bolt hole 51 is matched with a bolt 52. During installation, the cover 2 is placed on the tank body 1, the bolt holes 51 on the second flanges 50 are aligned, and the two second flanges 50 are connected by the bolts 52. The cover 2 and the tank body 1 are installed. After long-term use, the bolts 52 can be unscrewed, and the cover 2 can be removed from the tank body 1. The cover 2 drives the box body 10 out of the tank body 1, and the box body 10 can be cleaned.

[0021] Furthermore, as shown in the figure, the box body 10 described in this embodiment is provided with several second scrapers 60 that are in sliding contact with the inner wall of the box body 10. The second scrapers 60 are fixedly mounted on the second annular plate 61, and the second annular plate 61 is rotatably mounted on the rotating shaft 8 through a second one-way bearing. The second annular plate 61, the second scraper 60, and the rotating shaft 8 are coaxially arranged, and a slag discharge groove 62 is opened at the bottom of the box body 10, and a sealing cover 63 is provided in the slag discharge groove 62. When the output shaft of the motor 9 drives the rotating shaft 8 to rotate in the forward direction, the rotating shaft 8 cannot drive the second annular plate 61 and the second scraper 60 to rotate through the second one-way bearing. When the output shaft of the motor 9 drives the rotating shaft 8 to rotate in the reverse direction, the rotating shaft 8 drives the second annular plate 61 and the second scraper 60 to rotate through the second one-way bearing, and can scrape off impurities or scale attached to the inner wall of the box body 10. When the box body 10 is removed from the tank body 1, the sealing cover 63 is opened, and the impurities or scale in the box body 10 are discharged through the slag discharge groove 62, and then the sealing cover 63 is reinstalled in the slag discharge groove 62.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
