A kind of composite tap water filter device

Abstract

The invention discloses a combined type tap water filter device. The filter device comprises an upper shell, a lower shell, an intermediate, a water inlet, a water outlet, a drain outlet, an ultrafiltration membrane filament, an activated carbon fiber layer and a micro-filtration membrane layer; a plurality of purification filter devices for different uses are integrated into the combined type tap water filter device, the material cost is lowered, and the excessive pressure drop loss caused by the multi-stage filter device is avoided, the electric energy loss is reduced, and the device is environment-friendly and energy-saving. Furthermore, in combination of the reasonable shell device, the external pressure type ultrafiltration device is easy for draining and cleaning; and meanwhile, the user can unpick and wash the activated carbon fiber layer and the micro-filtration membrane layer, the device is simple and practicable, the activated carbon fiber can be cleaned with boiling water to be reused. In general, the service life of the filter device can be effectively increased, the cost of the existing whole tap water purification filter system can be greatly lowered, the material can be recycled, and the device is more economical and environment-friendly.

Description

technical field [0001] The invention relates to the technical fields of tap water filtration and purification of direct drinking water equipment, energy saving and environmental protection, and in particular to a composite tap water filtering device. Background technique [0002] Since the tap water is simply filtered and sterilized in the water plant, there are still many harmful substances in the water, such as: rust, sediment, colloid and other particles, bacteria, and odor, pesticide residues, residual chlorine, heavy metals, etc. Moreover, after the long-distance transmission of the pipeline, the rust and aging of the water pipeline, as well as the breeding of algae and bacteria, etc., are harmful to the human body. Therefore, it is necessary to filter the tap water layer by layer. At present, many domestic tap water filtration and purification In order to remove these harmful substances in the water, the filter equipment and the filter equipment on the direct drinking ...

Problems solved by technology

Moreover, after the long-distance transmission of the pipeline, the rust and aging of the water pipeline, as well as the breeding of algae and bacteria, etc., are harmful to the human body. Therefore, it is necessary to filter the tap water layer by layer. At present, many domestic tap water filtration and purification In order to remove these harmful substances in the water, the filter equipment and the filter equipment on the direct drinking water equipment basically adopt hierarchical and multi-stage filtration, and once the filter element is replaced, the entire filter device needs to be replaced or the entire filter element needs to be replaced. The waste of resources and the pressure on the environment will increase the cost of use for customers. At the same time, graded filtration will cause excessive pressure loss during the filtration process, requiring a booster, which will increase the power loss.
