Description

Technical Field

[0001] The utility model belongs to the technical field of building water saving, and more specifically, relates to a wastewater collection and reuse device. Background Art

[0002] my country's total freshwater resources amount to 2.8 trillion cubic meters, ranking sixth in the world. However, per capita water availability is only one-quarter of the global average, ranking 109th globally. my country is a severely water-scarce country, ranking among the top of over 40 countries facing severe water shortages. Industrial pollution has further exacerbated the shortage of available freshwater resources. Currently, most sections of my country's seven major river systems are severely polluted, and 86% of urban river sections exceed water standards.

[0003] At the same time, as my country's urban population grows, domestic water consumption is increasing. Households, as the smallest water-using unit in society, suffer from significant water waste. Water utilization is low, clean water is discharged into the groundwater system after only one use, and water with varying degrees of contamination is discharged uniformly without differentiation. This crude water use approach not only increases water waste but also places a greater strain on urban sewage treatment plants. Furthermore, there are currently no water-saving devices for households. Therefore, increasing water utilization and achieving multiple uses for water, with households as the water-saving unit, is becoming a future trend. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention.

In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "setting" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be a communication between the internal parts of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood based on specific circumstances.

[0024] Figure 1 The schematic diagram of the structure of one embodiment of the present invention is shown, specifically illustrating the structure of this embodiment. This embodiment relates to a closed water tank for collecting and reusing household wastewater. The suction function of the fan is used to reduce the air in the water tank, thereby changing the pipe pressure, forming a suction force, overcoming gravity, and collecting shower wastewater. When pressurized water is used, the blowing function of the fan is used to increase the gas pressure in the water tank, forming a pressurized water supply. When pressurized water is not required, it is only necessary to open the drain valve, and the gravity of the liquid level in the water tank can be used to make the water in the water tank flow out by gravity for cleaning the floor, etc. While improving the utilization rate of water resources, the fan increases the water tank pressure to achieve wastewater reuse. Pressurized flushing can be selected for toilets and floor adhesions.

[0025] A wastewater collection and reuse device, such as Figure 1-2 As shown, it includes a water tank and a power device, wherein the water tank is set to a cubic shape in this embodiment, and an air inlet and outlet are set on the top of the water tank. The fan is set on the outside of the top of the water tank and is fixedly connected to the air inlet and outlet; a water inlet and a water outlet are set on both sides of the bottom of the water tank, and the water inlet is connected to the water inlet device set on the outside of the water tank, and the water outlet is connected to the water outlet hose. Pipe interfaces are set at the water inlet and water outlet positions, which can be firmly connected to the water outlet pipe to prevent water from leaking out of the pipe body.

[0026] The water inlet device includes a first electric valve, a second electric valve, and a pressure detection device, which are arranged on the body of the water inlet pipe. The first electric valve and the second electric valve are arranged at different positions on the water inlet pipe and are respectively connected to the pressure detection device. The pressure detection device can detect the pressure level of the water inlet pipe and determine the amount of water flow based on the pressure level to control the opening and closing of the first and second electric valves and the degree of opening and closing. A liquid level detection device is provided in the water storage tank. In this embodiment, it is arranged at the top of the water storage tank and is respectively connected to the first electric valve, the second electric valve, and the third electric valve. When the water level in the water storage tank does not reach the position of the liquid level detection device, the first and second electric valves can be controlled to open and the third electric valve can be closed to allow water to enter and be stored. When the water level in the water storage tank reaches the position of the liquid level detection device, the first and second electric valves are closed. At this time, the third electric valve is closed to store water. At this time, the third electric valve is opened to allow wastewater to flow out, acting on the wastewater circulation.

[0027] When installing the device of this embodiment, the water tank needs to be placed on the ground, and the wash basin and shower pipes need to be laid along the ground; the shower as a whole is raised by 200 mm; and the drain valve 10 is connected to the drainage main.

[0028] The implementation process includes the following steps:

[0029] 1. When water is used for bathing and washing, waste water flows into the water storage tank 7 by gravity. When the pressure sensor 11 on the pipeline detects that the pressure is greater than the set value, the pipeline valve 9 is opened, the electric air outlet 2 is started in conjunction with the exhaust function of the fan 1, the air in the water storage tank is removed, the pressure increases, and suction is formed on the water inlet pipe.

[0030] 2. When the wastewater stops being discharged, the pressure sensor 11 on the water inlet pipe senses that the pressure drops to the set value, closes the pipe valve 9, stops the fan 1, closes the electric air vent 2, and stops the water inlet.

[0031] 3. When the water storage tank 7 reaches the maximum water storage capacity, the liquid level detector 3 links the water inlet pipe electric valve 9 to close, the air outlet 2 to close, the fan 1 to stop working, and the electric valve 10 to open. The water flows through the valve 10 and is discharged into the drainage pipe.

[0032] 4. When it is needed, open valve 6 and the water in the water storage can flow out by gravity.

[0033] 5. If pressurized water supply is required, turn on the blowing and pressurizing function of fan 1 to obtain pressurized water flow, which can be used for flushing toilets, washing the floor, etc.

[0034] The advantages and positive effects of this utility model are: due to the adoption of the above technical solution, the utilization rate of water is effectively improved, from the original single use to double use, the utilization rate is doubled, and the effectiveness of water resources is better utilized. While collecting wash basin drainage, it further solves the problem of shower drainage that is difficult to collect by gravity flow, so that shower wastewater can be reused twice.

[0035] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
