Embodiment Construction
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.
[0021] Such as figure 1 with 2 As shown, the intelligent automatic water purification system based on the PLC controller provided by the present invention has simple structure, scientific and reasonable design, and is easy to use. The operating efficiency of the purification system can effectively reduce the pressure in the pipeline connecting the fine filter and the reverse osmosis tank, thereby prolonging the service life of the pipeline, saving the use cost, effectively preventing the backflow of purified water, and effectively improving the reverse osmosis of the reverse osmosis tank effect to improve purification efficiency. The present invention comprises a water supply pipe 1 for purified water, a first primary filter 2 connected to the water supply pipe ...

Abstract
The invention discloses an intelligent automatic water purification system based on a PLC controller, which solves the problems of the filter in the prior art, which needs to be stopped for maintenance after failure, the pipeline water pressure is too high to shorten the service life of the pipeline, the purified water is prone to backflow, and automation low level problem. The present invention comprises a water delivery pipe for purified water, a first primary effect filter, a first fine filter, a reverse osmosis tank, an activated carbon filter, a centrifugal pump, a second primary effect filter, a second fine filter, a waste water collection tank, and a water supply pipe , the first booster tube, the first booster pump, the second booster tube, the second booster pump, a check solenoid valve, a pressure sensor and a PLC controller. The invention can carry out fault maintenance online, can effectively reduce the pressure in the pipeline connecting the fine filter and the reverse osmosis tank, prolongs the service life of the pipeline, saves the use cost, can effectively prevent the backflow of purified water, and can effectively improve the performance of the reverse osmosis tank Excellent reverse osmosis effect to improve purification efficiency and high degree of automation.
Description
technical field [0001] The invention relates to the technical field of water treatment, in particular to an intelligent automatic water purification system based on a PLC controller. Background technique [0002] The water purification system is a system that uses multi-stage filtration devices to purify water quality. Its function is to remove floating objects, heavy metals, bacteria, viruses, etc. in the water through filtration. It has high filtration technology. With the improvement of people's living standards, water purification systems have begun to enter people's families in large numbers, and have become household or indispensable supplies. In the prior art, the water purification system generally adopts multi-stage filtration, mainly including a pre-filter unit and a reverse osmosis filter unit. The reverse osmosis filter unit generally includes RO reverse osmosis membrane filtration technology. The output from the pure water port is pure water. The pre-filtratio...
