working principle:

When the chemical sewage enters the heat exchange tank 30 through the sewage inlet pipe 1, the manual steering adjustment handle 311 drives the driving rod 310 to rotate at a certain angle, and the driving rod 310 drives the corresponding rotating shaft 342 to rotate, so that the rotating shaft 342 drives the gear 341 to rotate and also drives the The metal gear ring 314 rotates, and the metal gear ring 314 drives several gears 341 and the rotating shaft 342 to rotate synchronously, and then drives the heat recovery fan 344 fixedly connected to the rotating shaft 342 to rotate at a certain angle. At this time, the hot sewage passes through every two adjacent heat recovery fans. Flow between the sheets 344 to the bottom of the heat exchange tank 30, clean water enters into the water collection tank 321 through the water inlet pipe 320, and enters the water inlet arc column 3447 and the inside of the water inlet arc tube 3445 along the water inlet pipe 321, when the heat recovery fan When the sheet 344 rotates, the water inlet arc tube 3445 slides in an arc-shaped limit along the water inlet arc column 3447, avoiding the disadvantages of the hose being easily fatigued by long-term stretching, so that the clean water flows along the water inlet arc tube 3445 through the water inlet 3444 Enter the water inlet tank 3441 inside the heat recovery fan 344, and enter the water outlet tank 3442 along the four water delivery channels 3443 connected with the water inlet tank 3441. During this period, the clean water in the four water delivery channels 3443 absorbs After the heat energy of the sewage on the heat recovery fan 344, the immersion tanks 3440 on both sides of the heat recovery fan 344 increase the contact area with the sewage to achieve the purpose of sufficient heat exchange. After the clean water enters the water outlet tank 3442, it passes through the conduit The water channel 3430 in the shaft 343 enters into the water collecting ring 331, enters into the four-way pipe 332 from three inlets along the water collecting ring 331, and then flows out to the water outlet pipe 333 through the bottom of the four-way pipe 332 , and then the clean water after recovering heat energy can be used as water for the factory area or provide hot water for nearby residents, which saves cost and energy consumption. The indicated scale value is the angle at which the heat recovery fan 344 rotates. The staff can observe through the transparent observation window 316. Through the scale value indicated by the pointer 312 on the dial 313, they can observe while rotating and adjusting the hand 311. View through the window 316, so as to accurately judge the angle of rotation.
