After the multistage centrifugal booster pump II 2-8 is started, wastewater to be treated in the water tank 2-26 sequentially passes through the filter cup 2-9, the multistage centrifugal booster pump II 2-8 and the atomizing nozzle 2-23 under the action of the multistage centrifugal booster pump II 2-8, and finally the wastewater to be treated in the water tank 2-26 is filtered by the filter cup 2-9 and is atomized by the atomizing nozzle 2-23 after being pressurized by the multistage centrifugal booster pump II 2-8 and then is sprayed to the surface of the rotating heating barrel 2-16.
The atomized wastewater to be treated is evaporated on the surface of the rotary heating barrel 2-16 to form steam and crystals, the crystals are adhered to the surface of the rotary heating barrel 2-16, the crystal removing device 2-17 is connected with the evaporation chamber of the lower box 2-22, the scraper 2-17-3 is contacted with the surface of the rotary heating barrel 2-16, the crystals adhered to the surface of the rotary heating barrel 2-16 are separated from the surface of the rotary heating barrel 2-16 by the crystal removing device 2-17, and fall into the crystal temporary storage chamber 2-22-4 of the lower box 2-22 through the iron sheet 2-17-2 and the blanking plate 2-17-1 of the crystal removing device 2-17.
Steam formed by evaporating the atomized wastewater to be treated on the surface of the rotary heating barrel 2-16 sequentially passes through the
In the evaporation process, when the wastewater in the water tanks 2-26 reaches the lowest water level, the multistage centrifugal booster pump I4 is started, the wastewater to be treated is injected into the water tanks 2-26 through the water inlet pipelines 2-10, and when the wastewater to be treated reaches the highest water level of the water tanks 2-10, the multistage centrifugal booster pump I4 is closed.
After crystal bodies in the crystal temporary storage chambers 2-22-4 of the lower box body 2-22 are fully stored, the temporary storage chamber door 2-22-6 is closed and opened, the crystal bodies in the temporary storage chambers 2-22-4 are cleaned manually, and finally the temporary storage chamber door 2-22-6 is closed.
Closing the motor 2-3, the multistage centrifugal booster pump I4 and the multistage centrifugal booster pump II 2-8 at intervals of 7 days (the time can be changed within a certain range, the range is 2 days to 15 days), opening the evaporation chamber door 2-22-1 of the lower box body 2-22, taking the water tank 2-26 in the lower part of the evaporation chamber 2-22-3 out of the evaporator 2 along the slide block guide rail 2-22-5, cleaning the sediment in the water tank 2-26, then loading the water tank 2-26 into the evaporator 2 along the slide block guide rail 2-22-5, closing the evaporation chamber door 2-22-1, and finally opening the motor 2-3, the multistage centrifugal booster pump I4 and the multistage centrifugal booster pump II 2-8.
The top of the scraper 2-17-3 of the crystal removing device 2-17 is contacted with the surface of the heating barrel 2-16, the scraper 2-17-3 is pushed back because of the circular runout of the surface of the heating barrel 2-16, the bolt for fixing the scraper 2-17-3 is sleeved with a spring 2-17-4, when the surface of the heating barrel 2-16 pushes the scraper 2-17-3, the spring 2-17-4 is compressed, when the surface of the heating barrel 2-16 is separated from the scraper 2-17-3, the spring 2-17-4 pushes the scraper 2-17-3, and the contact between the scraper 2-17-3 and the heating barrel 2-16 is kept all the time.
The brush 2-15 is contacted with the heating barrel 2-16, the brush 2-15 and the heating barrel 2-16 rotate simultaneously, and the brush 2-15 cleans the surface of the heating barrel 2-16 to remove residual crystals attached to the surface of the heating barrel 2-16 due to inconsistent linear velocity.
The foregoing shows and describes the general principles and features of the present invention. The present invention is not limited to the above-described embodiments, which are merely illustrative of the principles of the invention, but rather, various changes and modifications may be made therein without departing from the spirit and scope of the invention, which are to be protected thereby.
