The pressure in the middle section of the industrial water pipe is monitored by a second pressure gauge until the pressure reaches the preset value, thereby achieving a constant pressure supply of greywater.

Description

Technical Field

[0001] This utility model relates to the field of greywater reuse, specifically a constant pressure device for a greywater reuse system. Background Technology

[0002] Reclaimed water (also known as recycled water or reused water) is a type of water between tap water and sewage. Its core purpose is to alleviate water shortages through wastewater reuse. The treated water must meet standards such as the "Standardized Testing Method for Domestic Miscellaneous Water Use" to achieve the dual goals of water conservation and pollution reduction. Reclaimed water reuse refers to the technology of treating domestic sewage or industrial wastewater to meet specific water quality standards and reusing it in non-potable water applications. However, maintaining constant pressure during reclaimed water reuse can be challenging, thus affecting the supply efficiency.

[0003] To address the aforementioned issues, a constant pressure device for a greywater reuse system is proposed here. Utility Model Content

The inlet end of the first water pump is fixedly connected to a first inlet pipe, and the inlet end of the second water pump is fixedly connected to a second inlet pipe.

The water pressure at the end of the industrial water pipe is monitored by the first pressure gauge. If the pressure is lower than the preset value, the first pressure gauge will feed the information back to the corresponding control mechanism, thereby controlling the opening of the second and fourth solenoid valves, and the reclaimed water is introduced into the second outlet pipe through the second water pump, and then into the industrial water pipe. The pressure in the middle section of the industrial water pipe is monitored by the second pressure gauge until the pressure reaches the preset value, thereby achieving a constant pressure supply of reclaimed water.

[0020] Please see Figure 1-4This utility model provides a constant pressure device for a greywater reuse system, including a fixed base plate 1.

A filter box 9 is fixedly connected to one end of the greywater reuse pipe 8. A sealing tank 10 is snapped onto the end of the filter box 9 away from the greywater reuse pipe 8. A water guide pipe 11 is fixedly connected to the end of the sealing tank 10 away from the filter box 9. A first water outlet pipe 12 is fixedly connected to the outlet end of the first water pump 2, and a second water outlet pipe 16 is fixedly connected to the outlet end of the second water pump 3. An industrial water pipe 13 is fixedly connected to one end between the first water outlet pipe 12 and the second water outlet pipe 16. A first pressure gauge 14 is fixedly installed at the connection between the industrial water pipe 13 and the first water outlet pipe 12. A second pressure gauge 17 is fixedly installed at the connection between filter box 9 and the second outlet pipe 16. A mounting base 28 is fitted inside the filter box 9. The first filter screen 19, the second filter screen 20 and the third filter screen 21 are fixedly installed inside the mounting base 28 from left to right. By controlling the opening of the first solenoid valve 7 and the third solenoid valve 15, the greywater in the greywater recycling pipe 8 is introduced into the first outlet pipe 12 through the first water pump 2, and then into the industrial water pipe 13. The water pressure at the end of the industrial water pipe 13 is monitored by the first pressure gauge 14. If the pressure is lower than the preset value, the first pressure gauge 14 will feed the information back to the corresponding control mechanism, which will then control the opening of the second solenoid valve 6 and the fourth solenoid valve 18. The greywater is then introduced into the second outlet pipe 16 through the second water pump 3, and then into the industrial water pipe 13. The pressure in the middle section of the industrial water pipe 13 is monitored by the second pressure gauge 17 until the pressure reaches the preset value, thereby achieving a constant pressure supply of greywater.

[0021] A third solenoid valve 15 is fixedly installed at the connection between the first water outlet pipe 12 and the industrial water pipe 13. A fourth solenoid valve 18 is fixedly installed at the connection between the second water outlet pipe 16 and the industrial water pipe 13. A sealing ring 27 is fixedly installed at the connection between the filter box 9 and the sealed tank 10. A mounting bracket 23 is fixedly installed at the connection between the filter box 9 and the mounting base 28. A mounting slot 22 is opened at the connection between the mounting base 28 and the filter box 9. The mounting slot 22 and the mounting bracket 23 are engaged and connected.

[0022] In use, the third solenoid valve 15 and the fourth solenoid valve 18 facilitate the control of the introduction of the medium water in the first water outlet pipe 12 and the second water outlet pipe 16 into the industrial water pipe 13. The sealing ring 27 can play a sealing role. The limiting engagement of the mounting slot 22 and the mounting seat 23 facilitates the initial limiting of the mounting seat 28.

A first solenoid valve 7 is fixedly installed in the middle of the first water inlet pipe 5.

[0024] In use, the mounting base 28 is further limited by the limiting engagement of several connecting holes 24 with several connecting blocks 25. The arc-shaped chamfer 26 makes it easy to snap the connecting blocks 25 into the connecting holes 24. The introduction of water is controlled by the first solenoid valve 7 and the second solenoid valve 6.

[0025] In this embodiment, the following steps are taken: By controlling the opening of the first solenoid valve 7 and the third solenoid valve 15, the reclaimed water in the reclaimed water recycling pipe 8 is introduced into the first outlet pipe 12 via the first water pump 2, and then into the industrial water pipe 13. The water pressure at the end of the industrial water pipe 13 is monitored by the first pressure gauge 14. If the pressure is lower than the preset value, the first pressure gauge 14 will feed the information back to the corresponding control mechanism, thereby controlling the opening of the second solenoid valve 6 and the fourth solenoid valve 18. The reclaimed water is then introduced into the second outlet pipe 16 via the second water pump 3, and then into the industrial water pipe 13. The pressure in the middle section of the industrial water pipe 13 is monitored by the second pressure gauge 17 until the pressure reaches the preset value, thereby achieving a constant pressure supply of reclaimed water.
