Embodiment Construction

[0014] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0015] Such as figure 1 , figure 2 As shown, the bathing wastewater filtering sewage device is located between the water accumulation pan for bathing wastewater drainage and the waste hot water recovery device, and includes a water accumulation pan 1 , an overflow filter 3 and a reversing valve 2 . in:

[0016] The water accumulation tray 1 is a body for collecting waste water, its bottom is connected with a reversing valve device 2, and the overflow filter 3 of the present invention is built in its body. The water collecting tray 1 can be made of acrylic material by injection molding.

[0017] The reversing valve device 2 includes an inner casing 21 , an outer casing 22 and a sealing ring 23 between the inner casing 21 and the outer casing 22 . Among them: such as image 3 , as shown in Figure 4, the above-mentioned inner sleeve body 21 is the...

Abstract

A filter and drainage apparatus for the used bath water is composed of water collector, overflow filter in the water collector, and a commutating valve connected to the bottom of water collector for communicating the filter to either recovering unit or sewer. Its method includes such steps as filtering, backflushing the filter, and delivering the used water to either recovering unit or sewer.

Description

technical field [0001] The invention relates to a device and method for filtering and discharging sewage from bathing, in particular to a device and method for filtering and discharging sewage, which can filter and purify bathing wastewater and have the function of backwashing, and are used in conjunction with recovery devices such as heat exchangers and waste water reuse. Background technique [0002] In order to save water resources and heat energy, bath wastewater can be recycled and reused. An indispensable link in the process of recycling bath wastewater is the filtration and purification of wastewater. For example, the existing heat exchangers can fully recycle the waste heat generated by bathing wastewater in households and public places, etc., and have high heat exchange efficiency, so they have been recognized by people, but they have not been used in actual use. achieve the best application effect. The reason is that the bathing wastewater directly enters the hea...
