Description

Technical Field

[0001] This utility model relates to the field of factory water supply technology, specifically to a multi-container stepped water supply device. Background Technology

[0002] Large factories typically have water tanks for water supply. Since factories require various water sources, such as tap water, boiler feedwater (water after waste heat recovery), and circulating water for compressor cooling, and because these three water sources may have different temperature requirements, multiple water tanks are usually installed within the factory to hold different water sources. However, because multiple water tanks occupy a large amount of space, some factories may combine all three into one tank. This can easily lead to heat exchange between the three different temperatures, thereby lowering the temperature of the boiler feedwater and increasing the energy required for boiler heating, thus increasing energy consumption.

To achieve the above objective, this utility model provides the following technical solution: it includes several water storage chambers located inside a centralized tank, with adjacent water storage chambers connected by a connecting pipe. A buoyancy valve assembly is provided on the connecting pipe. Each water storage chamber is equipped with an inlet pipe and an outlet pipe.

[0019] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0020] Example: Please refer to Figure 1-2 A multi-container stepped water supply device includes several water storage chambers 1 located inside a centralized tank 2. Adjacent water storage chambers 1 are connected by a connecting pipe 15, which is equipped with a buoyancy valve assembly 6. Each water storage chamber 1 has an inlet pipe 5 and an outlet pipe 3. There are three water storage chambers, arranged from bottom to top as a boiler return water chamber, a circulating water chamber, and a tap water chamber. This prevents heat exchange between the three types of water, thus avoiding impact on the boiler feedwater temperature, reducing the energy required for boiler heating, and decreasing energy consumption. The inlet pipe 5 of the boiler return water chamber is connected to the outlet of the boiler waste heat recovery system, and the outlet pipe 3 of the boiler return water chamber is connected to the boiler heating water tank. The boiler waste heat recovery system uses a conventional plate heat exchanger, which will not be elaborated further here. This connection method greatly improves energy utilization and reduces the amount of natural gas used in the boiler. The inlet pipe 5 of the circulating water chamber is connected to the outlet of the compressor's cooling chamber, and the outlet pipe 3 of the circulating water chamber is connected to the radiator. The inlet pipe 5 of the tap water chamber is connected to the municipal water supply, and the outlet pipe 3 of the tap water chamber is connected to the inlet of the compressor's cooling chamber. The outlet pipe 3 of the tap water chamber is also connected to the domestic water supply pipe, ensuring that the compressor can effectively dissipate heat while providing domestic water. Each water storage chamber 1 has a water level scale on its side wall for easy water level monitoring. The outlet pipe 3 of the boiler return water chamber is also connected to the cleaning water network for easy cleaning inside the factory. The outer wall of the boiler return water chamber is also equipped with an insulation layer to prevent heat loss from the boiler return water. Several inlet pipes 5 and outlet pipes 3 are equipped with water pumps, and each water storage chamber 1 is equipped with a liquid level sensor. Both the water pumps and the liquid level sensors are connected to the controller to control the water inlet and outlet of the water storage chamber 1. Further details are omitted here.

[0021] In this embodiment, the connecting pipe 15 is provided with a water outlet groove 13 and a limiting boss 14. The limiting boss 14 is located above the water outlet groove 13. The buoyancy valve assembly 6 includes a piston head 8 that is slidably connected to the inside of the connecting pipe 15. A buoyancy rod 10 is fixedly connected to the bottom of the piston head 8. A float ball 4 is fixedly connected to the end of the buoyancy rod 10 away from the piston head 8. Under the buoyancy generated by the float ball 4, the piston head 8 is tightly attached to the limiting boss 14. When the flow rate of the inlet pipe 5 of the boiler return water chamber is lower than the flow rate of the outlet pipe 3 of the boiler return water chamber, and the water level drops to the set minimum water level, the piston rod will move downward. This allows water (at a higher temperature than tap water) in the circulating water chamber to flow into the boiler return water chamber for replenishment; a baffle 9 is provided at the bottom of the connecting pipe 15, a buoyancy rod 10 passes through the baffle 9, a support plate 11 is provided on the buoyancy rod 10, and a compression spring 12 is sleeved on the buoyancy rod 10 between the support plate 11 and the baffle 9, which improves the reset quality of the piston head 8 when it moves down to expose the water tank 13, ensuring that water can flow from the upper water storage chamber 1 into the lower water storage chamber 1; and several reinforcing ribs 7 are distributed circumferentially at the bottom of the partition between adjacent water storage chambers 1 to prevent the partition from breaking under water pressure.

[0022] The working principle of the embodiment: This utility model has three water storage chambers 1, and the connection between two adjacent water storage chambers 1 is controlled by the buoyancy valve assembly 6; thereby preventing direct heat exchange between the three types of water and affecting the temperature of the boiler feedwater; thereby reducing the energy used for boiler heating and reducing energy consumption.
