原水进水管101的远端连通自来水管或原水储水桶。The far end of the raw water inlet pipe 101 is connected to a tap water pipe or a raw water storage bucket.
中间滤芯2为超滤膜滤芯。The middle filter element 2 is an ultrafiltration membrane filter element.
工作原理:当净水机开启后,原水从原水进水管101依次通过稳压阀和单向阀流进前置滤芯1。原水经过前置滤芯1过滤后得到净水。净水通过净水管一105进入中间滤芯2进一步进行过滤,过滤后的净水再通过净水管二201进入RO反渗透滤芯3中进行过滤得到纯水。Working principle: When the water purifier is turned on, raw water flows from the raw water inlet pipe 101 through the pressure stabilizing valve and the one-way valve into the pre-filter element 1. The raw water is filtered through the pre-filter element 1 to obtain purified water. The purified water enters the intermediate filter element 2 through the water purification pipe 105 for further filtration. The filtered water then enters the RO reverse osmosis filter element 3 through the water purification pipe 201 for further filtration to obtain pure water.
前置滤芯1进行过滤得到净水时,会在原水端产生废水,废水经过废水排出管103排进废水桶5,同时,RO反渗透滤芯3过滤得到纯水的同时在反渗透净水端会产生浓水,浓水通过浓水排出管301排进废水桶5中。When the pre-filter element 1 performs filtration to obtain purified water, wastewater will be generated at the raw water end. The wastewater will be discharged into the wastewater barrel 5 through the wastewater discharge pipe 103. At the same time, when the RO reverse osmosis filter element 3 filters to obtain pure water, wastewater will be generated at the reverse osmosis purified water end. Concentrated water is generated, and the concentrated water is discharged into the waste water barrel 5 through the concentrated water discharge pipe 301.
浊度检测器8以及液位传感器9会实时采集浊度和液位,并将数据上传至中控器。The turbidity detector 8 and the liquid level sensor 9 will collect the turbidity and liquid level in real time and upload the data to the central controller.
当位于前置滤芯1内的浊度检测器8检测到原水端的浊度大于中控器内预设的浊度上限,且废水桶5内的浊度检测器8检测的浊度小于废水桶5预设浊度时,中控器会发出指令打开废水回水管102上的电磁阀6和增压泵7,这时废水桶5内的废水回流至前置滤芯1并对前置滤芯1进行冲洗,冲洗后的废水通 过废水排出管103排放至废水桶5。当前置滤芯1内的浊度检测器8检测到的浊度低于预设浊度下限时,中控器接收到该信息并发出指令关闭废水回水管102上的电磁阀6和增压泵7,停止对前置滤芯1的冲洗。此时,废水桶5内的浊度检测器8检测到的浊度大于废水桶5预设的浊度值时,中控器打开污水排出管501上的电磁阀6,将废水桶5内的污水排放至下水道,反冲洗结束。若此时废水桶5内的浊度检测器8检测到的浊度低于废水桶5预设的浊度值时,反冲洗结束。When the turbidity detector 8 located in the pre-filter element 1 detects that the turbidity of the raw water end is greater than the preset turbidity upper limit in the central controller, and the turbidity detected by the turbidity detector 8 in the waste water barrel 5 is less than the waste water barrel 5 When the turbidity is preset, the central controller will issue instructions to open the solenoid valve 6 and booster pump 7 on the wastewater return pipe 102. At this time, the wastewater in the wastewater barrel 5 will flow back to the pre-filter 1 and flush the pre-filter 1. , the flushed wastewater is discharged to the wastewater barrel 5 through the wastewater discharge pipe 103. When the turbidity detected by the turbidity detector 8 in the front filter element 1 is lower than the preset turbidity lower limit, the central controller receives this information and issues an instruction to close the solenoid valve 6 and booster pump 7 on the wastewater return pipe 102 , stop flushing the pre-filter element 1. At this time, when the turbidity detected by the turbidity detector 8 in the waste water barrel 5 is greater than the preset turbidity value of the waste water barrel 5, the central controller opens the solenoid valve 6 on the sewage discharge pipe 501 to discharge the turbidity in the waste water barrel 5. The sewage is discharged to the sewer and backwashing is completed. If the turbidity detected by the turbidity detector 8 in the waste water barrel 5 is lower than the preset turbidity value of the waste water barrel 5 at this time, the backwashing ends.

At the same time, the central controller issues instructions to open the solenoid valve 6 and the water pump on the backwash return pipe 104. At this time, the clean water filtered by the pre-filter 1 is returned through the backwash return pipe 104 to flush the pre-filter 1. The flushed wastewater is discharged into the wastewater barrel 5 through the wastewater discharge pipe 103. When the turbidity detected by the turbidity detector 8 in the front filter element 1 is lower than the preset turbidity lower limit, the central controller issues an instruction to close the backwash return. The solenoid valve 6 and booster pump 7 on the water pipe 104, and at the same time, if the turbidity value detected by the turbidity detector 8 in the waste water barrel 5 is less than the preset turbidity value of the waste water barrel 5, the central controller will issue a command to close Solenoid valve 6 on the sewage drainage pipe. At this time, backwashing ends.
当废水桶5上的液位传感器9检测到液位达到设定的液位上限时,中控器发出指令开启污水排水管上的电磁阀6,将废水桶5中的废水排出。当的液位传感器9检测到液位小于设定的液位下限时,中控器发出指令关闭污水排水管上的电磁阀6,继续收集废水。When the liquid level sensor 9 on the waste water barrel 5 detects that the liquid level reaches the set upper limit, the central controller issues an instruction to open the solenoid valve 6 on the sewage drainage pipe to discharge the waste water in the waste water barrel 5. When the liquid level sensor 9 detects that the liquid level is less than the set lower limit of the liquid level, the central controller issues an instruction to close the solenoid valve 6 on the sewage drainage pipe and continue to collect wastewater.
