China Resources Snow Beer Bottle Washing Machine Project
China Resources Snow Breweries (China) Co., Ltd. was established in 1994 and is a national professional beer company engaged in the production and operation of beer. Jinan Fumide Environmental Protection signed a contract with China Resources Snow Breweries to apply self-cleaning filters in the wastewater system of Snow Beer bottle washing machines for recycling and reuse. The filters mainly remove pulp and solid impurities from high-temperature alkaline cleaning liquid. The self-cleaning filter uses PLC control for short backwash time, low sewage water consumption, and water resource saving. The automatic cleaning control reduces manual cleaning time and workload, greatly improving the efficiency of the production system and completely replacing the previously used Y-type ordinary filter device.
Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle. Cleaning process: The cleaning mechanism of the fully automatic negative pressure suction filter is a stainless steel spiral up-and-down moving suction scanner. It is hollow in structure, with several suction nozzles vertically distributed at certain distances along its axis. The inside of the suction scanner communicates with the 3” drain valve. When the drain valve opens, the pressure difference between the internal water pressure of the filter and the external atmospheric pressure generates strong suction at each suction nozzle. At each suction nozzle, water flows rapidly from outside to inside in reverse, washing impurities attached to the inner wall of the filter screen into the suction nozzle, through the hollow shaft of the suction scanner, then discharged through the drain valve, completing the cleaning process which takes about 30-60 seconds. At this time, the pressure difference returns to normal, the cleaning process ends, and filtration resumes. During cleaning, the system continues to flow.
