Description

Manual Water-saving water tank

technical field

The utility model relates to a reclaimed water device for buildings.

Background technique

In order to realize urban sewage and wastewater recycling, save water, control pollution, and protect the environment, people began to pay attention to setting up reclaimed water systems in construction projects. Reclaimed water system refers to an organic combination composed of engineering facilities such as collection, storage, treatment and supply of reclaimed water. It is one of the functional supporting facilities of a building or a building community. The raw water of reclaimed water mostly adopts high-quality miscellaneous drainage, that is, drainage with a low degree of pollution, such as cooling drainage, swimming pool drainage, bathing drainage, toilet drainage, laundry drainage, etc. When high-quality miscellaneous drainage or miscellaneous drainage is used as the reclaimed water source, the technological process mainly based on physical and chemical treatment, or the technological process combining biological treatment and physical and chemical treatment is adopted. Reclaimed water in buildings is mostly used to flush toilets. That is to say, for residential buildings, it collects the drainage of kitchen sinks, bathtubs, washing machines and other equipment, rainwater, and air-conditioning cooling drainage through the special indoor drainage pipes to the reclaimed water treatment station after treatment and then uses the reclaimed water supply pipes. Delivered to restrooms. It can be seen that this kind of reclaimed water system has a large investment, including the drainage system for collecting raw water, reclaimed water treatment equipment and station buildings, reclaimed water supply system, etc., and the maintenance and operation costs are high. Therefore, reclaimed water projects are still difficult to implement and difficult to promote.

Detailed ways

In conjunction with the accompanying drawings, the utility model is further described through embodiments.

The water-saving water tank includes a tank body 4, a water inlet mechanism, a water outlet mechanism and accessories.

The box body 4 can be made of plastic or ceramic material, and the production cost is low. The box body 4 is provided with a scum opening, an overflow pipe, a flushing pipe and a shelf 1, which can improve the strength and rigidity of the box body 4. The bottom surface of the box body 4 is designed as an inclined plane to facilitate the accumulation and removal of silt, as shown in Fig. 1 and Fig. 2 .

Its water inlet mechanism includes three horizontal tap water inlet pipes 10, a raw water inlet pipe 11 and a vertical water inlet pipe 12 installed on one side of the upper part of the tank; a floating ball 16 is installed at the pipe end of the tap water inlet pipe 10, which is sprayed by a special nozzle. The flushing filter screen 22 is also used as the supply water when the water level of the tank is lower than the critical water level; the vertical water inlet pipe 12 can be used to collect the drainage of equipment such as washing boxes, upper drainage washing machines and the like. A high-pressure water inlet pipe 24 with a water pump 23 is installed on the other side of the upper part of the casing. A vertically downward flushing pipe 9 is installed on the casing 4 at the water outlet of the water pump 23. The lower port of the flushing pipe 9 is a wedge-shaped mouth. With the help of the flushing water flow of the flushing pipe 9, the sediments such as silt on the bottom surface of the box body are removed through the mud discharge port 6, the drain elbow 19 and the drain valve 14. Water pump 23 is used for extracting the drainage of equipment such as bathtub, shower tray, lower drainage washing machine that water level is lower, and water pump 23 can be manually controlled by switch, also can be automatically controlled by control box.
