Abstract

The invention discloses an intelligent full-automatic pre-filter. The pre-filter comprises a cover body, a cylindrical body, a filter screen and an electronic control system, wherein the cylindrical body is mounted at the lower end of the cover body; the filter screen is arranged inside the cylindrical body; a water inlet valve and a water outlet valve are arranged at two ends of the cover body; a sewage outlet is formed in the lower end of the cylindrical body; the electronic control system is mounted inside the cover body; the electronic control system comprises a power source, an LCD screen, a time setting module, a washing module and connecting wires, and is used for selecting working modes and setting the period, time and water consumption of back washing. The pre-filter has the following advantages: 1) the pre-filter is intelligent, automatic in back washing, free from manual operation, adjustable in period and time of back washing and high in adaptive capacity; 2) the automatic working mode and the manual working mode are available, and the operation flexibility is high; 3) by adopting the dual functions of DC and AC, the phenomenon that the pre-filter cannot be used in areas without power sources is avoided; 4) the pre-filter is relatively high in filter precision, east to wash, firm and durable; 5) the pre-filter is high in visual degree; 6) a water inlet is provided with a pressure reducing valve, and the working stability is improved.

Description

technical field [0001] The invention relates to the field of water purification equipment, in particular to an intelligent fully automatic pre-filter. Background technique [0002] At present, due to the outdated urban water supply pipelines, the production pipelines are corroded and contain silt, a large amount of precipitated impurities are produced in the tap water pipe network, which is harmful to human health. The pre-filter is a reliable impurity filtering device. It is usually installed behind the water meter in the water inlet pipe. Its main function is to filter the sediment, rust, and large particles in the tap water, restore the tap water to the standard before leaving the factory, and protect the downstream Equipment, and play a positive role in protecting hidden pipelines, faucets, electrical appliances, etc. Existing pre-filter products do not have an automatic backwashing function. Usually, it is necessary to remove the pre-filter to flush or perform backwash...
