[0020] In order to clearly illustrate the technical features of the present application, the utility model is described in detail below, and the utility model is described in detail below by combining with the drawings.

[0021] It should be noted that, in the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from the description. Therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0022] For example, Figures 1-3The utility model provides a high salt wastewater heat exchange device, including horizontal heat exchange bin 100, cooling liquid circulating pump 200 and cleaning and heat exchange component.

[0023] Among them, cleaning and heat exchange component includes motor 310 who sets outside horizontal heat exchange bin 100, hollow rotating shaft 320 who sets in horizontal heat exchange bin 100 and several scrapers 330 who sets in horizontal heat exchange bin 100.

[0024] Specifically, the output shaft of motor 310 is fixedly connected with a belt pulley one. The two ends of hollow rotating shaft 320 are rotatably connected with the two ends of horizontal heat exchange bin 100. The two ends of hollow rotating shaft 320 pass through the horizontal heat exchange bin 100 and are connected with the liquid inlet pipe and the liquid outlet pipe of cooling liquid circulating pump 200 through rotary joints respectively. The end of hollow rotating shaft 320 is fixedly sleeved with a belt pulley two, and the belt pulley two is connected with the belt pulley one through a belt 340. The scrapers 330 are arranged close to the inner wall of horizontal heat exchange bin 100 and are parallel to hollow rotating shaft 320. The two ends of scrapers 330 are fixed on hollow rotating shaft 320 through connecting rods 350.

[0025] The top of one end of horizontal heat exchange bin 100 is provided with a feeding port 110, and the bottom of the other end of horizontal heat exchange bin 100 is provided with a discharge port 120. A control valve 130 is installed on the discharge port 120.

[0026] During operation, high-salt wastewater is added to horizontal heat exchange bin 100 from feeding port 110, and cooling liquid is pressed into hollow rotating shaft 320 by cooling liquid circulating pump 200. The high-salt wastewater is cooled by the cooling liquid, and the high-salt wastewater after heat exchange is discharged from discharge port 120 for collection. The opening of control valve 130 can be adjusted to adjust the heat exchange time of high-salt wastewater.

[0027] After the cooling liquid is discharged from hollow rotating shaft 320, it is sent to a cooling unit for cooling and then returned to hollow rotating shaft 320 for use.

[0028] At the same time, the rotation of motor 310 drives the rotation of belt pulley one, which in turn drives the rotation of belt pulley two through belt 340, and further drives the rotation of hollow rotating shaft 320. The rotation of scrapers 330 with hollow rotating shaft 320 can scrape off the salt and impurities attached to the inner wall of horizontal heat exchange bin 100, avoiding the corrosion of the inner wall of horizontal heat exchange bin 100 and greatly improving the service life of the equipment.

[0029] Further, a spiral blade 400 is arranged on hollow rotating shaft 320 to feed the discharge port 120. During the rotation of spiral blade 400 with hollow rotating shaft 320, it plays a role in stirring and conveying high-salt wastewater.

[0030] Furthermore, the spiral blade 400 is hollow, and the cavity inside the spiral blade 400 is connected to the hollow rotating shaft 320. Due to centrifugal force, the coolant inside the hollow rotating shaft 320 can easily enter the cavity of the spiral blade 400, increasing the effective heat exchange area and improving the heat exchange efficiency.
