Movable water purifier and control method thereof

Abstract

The invention provides a movable water purifier and a control method thereof. The movable water purifier comprises a raw water tank, a pure water tank, a control panel, a pure water pipe and a concentrated water pipe, the pure water pipe and the concentrated water pipe are controlled by a PLC, the starting end of the pure water pipe is connected with the raw water tank, and the end, connected withthe raw water tank, of the pure water pipe is provided with a filter screen, the stopping end of the pure water pipe is connected to a reverse osmosis membrane group, a water suction pump, a low-pressure switch, a first water quality sensor, a float switch, an ultrafiltration membrane group, a third electromagnetic valve, a high-pressure water pump and the reverse osmosis membrane group are sequentially arranged on the pure water pipe, a pure water port of the reverse osmosis membrane group is connected with the starting end of a water production pipe, and the stopping end of the water production pipe is connected with the pure water tank. The invention further discloses the movable water purifier and the control method thereof, water changing can be reminded in time when the raw water tank lacks water, standby protection is achieved, sufficient water resources are guaranteed, forward and reverse flushing and standby protection are conducted when the pure water tank is full of water,the interior of a pipeline is kept clean, waste of the water resources and excessive consumption of the system are avoided, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a mobile water purifier and a control method thereof. Background technique [0002] At present, the water inlet end of the pure water system used by the tea bar machine in the prior art is to use a water pump to extract the raw water in the water tank or bucket for filtration. This method needs to check frequently whether there is water shortage in the water tank or bucket, and then replace the water tank or water tank. Raw water in the bucket, at the same time, after the filtered water tank is filled with water, the pumping from the water tank or bucket is not stopped in time, resulting in the overflow of the filtered water tank, resulting in waste of water resources and excessive consumption of the system, consuming a lot of resources and Not conducive to use. Contents of the invention [0003] The invention provides a mobile water purifier and its control ...
