Description

Technical Field

[0001] This utility model relates to the field of water storage tank technology, and in particular to an energy-saving water storage tank without negative pressure. Background Technology

[0002] The box-type negative pressure-free water supply system mainly consists of a sealed water tank, a water intake device, a booster device, a main pump unit, a frequency converter control cabinet, a pressure maintaining device, a negative pressure-free flow controller, a flow stabilizing tank, and pipelines. Its working principle is to store tap water in a sealed water tank before pressurizing it for users. During off-peak hours, the tap water pressure meets user needs and is supplied through the municipal water network. During peak hours, when the tap water pressure is insufficient, the water in the sealed tank is pressurized and supplied to users, thus meeting their water needs at any time.

[0003] Chinese Patent Publication No. CN218116634U discloses a negative pressure-free water supply tank, comprising four sets of rectangular plate seats, with one additional plate seat mounted on top of each of the four sets of plate seats, and nine mounting seats mounted on each set of plate seats. A base frame is mounted at the bottom of each plate seat, and the base frame is composed of a "W"-shaped frame and a "V"-shaped frame. Bases located on both sides of the base frame are fixedly installed at the bottom of each plate seat, and pump seats are fixedly installed on the outer walls of the bases. Nine circular water troughs are formed on the inner side of each plate seat, and nine mounting slots are formed on the outer walls of the plate seats, located outside the water troughs. Through the base frame at the bottom of the plate seats, when water in the inner space of the four sets of plate seats settles for a long time, it automatically falls into the "V"-shaped slots on the inner side of the base frame. The pump seats, in conjunction with the drain seat, then output the water containing sediment from the inner side of the base frame, ensuring the device's sewage discharge effect and solving the problem of poor sewage discharge in existing flat-bottomed water tanks.

[0004] The existing technical solutions have the following shortcomings: during use, the lack of a measuring device in the component design makes the control of negative pressure inaccurate, resulting in over-pressurization or under-pressurization, which also indirectly leads to resource waste. There is room for optimization. Therefore, it is necessary to design an energy-saving negative pressure-free water tank to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide an energy-saving negative pressure-free water storage tank to solve the problem mentioned in the background art, where the lack of a measuring device in the component design leads to inaccurate control of negative pressure, resulting in over-pressurization or under-pressurization, which also indirectly causes resource waste.

The top of the water storage tank is connected to the water outlet pipe, and the top of the water outlet pipe is connected to the water supply pipe. A water exchange pump is fixed to one side inside the water storage tank. The water supply pipe and the water outlet pipe are connected by a connecting flange and a first bolt. The two ends of the water exchange pump are respectively connected to a first connecting water pipe and a second connecting water pipe. A water purification filter cartridge is fixed to one side inside the water storage tank. One end of the first connecting water pipe is connected to...

An air tank is set at the top of the water storage tank, and a cover plate is connected to the top of the tank.

[0024] Please see Figures 1-6 An embodiment of this utility model is provided: an energy-saving negative pressure-free water storage tank, including a water supply pipe 1, a water storage tank 13, and a water outlet pipe 19;

[0025] A pressure gauge 12 is connected to the top of the water storage tank 13, and an inspection door 20 is hinged to one side of the water storage tank 13. The output end of the pressure gauge 12 is electrically connected to the input end of the controller 24 through a wire. The output end of the controller 24 is electrically connected to the input ends of the first solenoid valve 3, the second solenoid valve 7, the water exchange pump 9, and the air exchange pump 17, respectively.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, during use, the inside of the water storage tank 13 is inspected through the inspection door 20, and the pressure inside the water storage tank 13 is measured by the pressure gauge 12 and the data is input to the controller 24 to issue instructions.

[0027] A water outlet pipe 19 is connected through the top of the water storage tank 13, and a water supply pipe 1 is connected to the top of the water outlet pipe 19. A water exchange pump 9 is fixed inside the water storage tank 13 on one side. The water supply pipe 1 and the water outlet pipe 19 are connected by a connecting flange 4 and a first bolt 5. The two ends of the water exchange pump 9 are respectively connected to a first connecting water pipe 10 and a second connecting water pipe 11. A water purification filter cartridge 8 is fixed inside the water storage tank 13 on one side. One end of the first connecting water pipe 10 is connected to the bottom end of the water purification filter cartridge 8. A three-way pipe 6 is fixedly connected to the top of the water purification filter cartridge 8. A water storage tank 2 is connected to the top of the water storage tank 13, and the bottom end of the water storage tank 2 is connected to the three-way pipe 6. A top air tank 25 is fixed to the top of the water storage tank 13.

[0028] Air passages 26 are evenly provided on the top of the outer side of the top air tank 25, and the cross-section of each air passage 26 is circular.

[0029] Specifically, such as Figure 2 As shown, during use, the external gas is absorbed through the top air tank 25 to replenish the pressure of the water storage tank 13. Due to its circular structure, it has a large surface area in contact with the air, resulting in a good replenishment effect.

[0030] Furthermore, an air exchange pump 17 is fixed inside the top air tank 25. One end of the air exchange pump 17 is connected to a first air pipe 16, and the other end of the air exchange pump 17 is connected to a second air pipe 18. The bottom end of the second air pipe 18 penetrates the interior of the water storage tank 13. A controller 24 is connected to the outside of the water storage tank 13, and the controller 24 is electrically connected to a first solenoid valve 3 and a second solenoid valve 7.

The top of the air filter element 15 is evenly provided with mounting grooves 23, and the inside of each mounting groove 23 is threadedly connected to a second bolt 21 through the cover plate 14.

[0032] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, when in use, first install the air filter element 15 inside the top air tank 25, and then seal the cover plate 14 to the top of the air filter element 15 with the second bolt 21 and the gasket 22.

[0033] Working principle: When this utility model is in use, when the water supply pipe 1 stops supplying water, the water storage tank 13 generates negative pressure, which is monitored by the pressure gauge 12 and fed back to the controller 24, which starts the air exchange pump 17 to draw air from the outside to replenish the inside of the water storage tank 13.

[0034] Secondly, when water accumulates in the storage tank 13, the water exchange pump 9 is started to drive water into the water purification filter cartridge 8 for circulation filtration, absorbing the substances precipitated in the storage tank 13 into the water purification filter cartridge 8. At this time, the second solenoid valve 7 is opened and the first solenoid valve 3 is closed.

[0035] Finally, after the circulation filtration ends, the first solenoid valve 3 is activated and the second solenoid valve 7 is closed to fill the water tank 2 with water for replenishment. Then, the water exchange pump 9 and the first solenoid valve 3 are turned off, thereby achieving the function of energy saving and no negative pressure.
