Problems solved by technology

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 heat exchanger for water heat exchange without filtering and sewage treatment. Over time, the waste in the bathing wastewater will block and corrode the heat exchange tubes, so that the heat exchanger will not reach its service life. stop working

Embodiment Construction

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

[0015] As shown in Fig. 1 and Fig. 2, the bathing waste water filtering sewage device is matched with the waste hot water recovery device, and includes a water accumulation tray 1, an overflow filter 3 and a reversing valve 2. in:

[0016] The water storage tray 1 is a body for collecting waste water, and its bottom is assembled and connected with the lower part of the reversing valve device 2, and the overflow filter 3 of the present invention is placed in its inner cavity. 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 . Wherein: as shown in Fig. 3 and Fig. 4, the above-mentioned inner sleeve body 21 is an intermediate connection structure between the fi...

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...
