Description

Technical Field

[0001] This utility model relates to the technical field of heat exchange station equipment, and in particular to a branch water supply device for a heating pipeline network. Background Technology

[0002] Central heating systems are generally closed pressurized systems, and leaks are very common due to various reasons such as loose pipe welds or pipe aging.

[0003] Existing heating network branch water supply devices, such as the automatic energy-saving constant pressure water supply device for heating networks disclosed in utility model patent application number 201821495473.3, mainly include a water supply component and a constant pressure component. The water supply component includes a boiler and a heating network, with the heating network connected to the boiler. The heating network is divided into two sections, front and rear. A first pressure transmitter and a second pressure transmitter monitor the water pressure of the front and rear sections of the heating network, respectively. In use, hot water is drawn from the boiler by the first water supply pump, then flows along the front section of the heating network to the second water supply pump, and then the second water supply pump discharges the hot water to the rear section of the heating network. As the hot water flows through the heating network, it exchanges heat with the outside through the heating network.

[0004] However, most existing water supply devices directly replenish the heating network with tap water, which not only leads to a decrease in network temperature, failing to meet heating requirements, but also causes scale and rust to form inside the pipes due to hard water, reducing the service life of the pipes. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a heating network branch water supply device that can not only generate insoluble precipitates of calcium and magnesium ions in tap water, preventing them from forming precipitates or altering the pipes and extending the service life of the pipe network, but also heat soft water to ensure the water temperature in the heating network.

[0006] This utility model discloses a heating network branch water replenishment device, comprising a heating mechanism; it also includes a filtration mechanism, a stirring mechanism, a water replenishment mechanism, and a detection mechanism. The filtration mechanism is installed on the heating mechanism to separate soft and hard water; the stirring mechanism is installed on the heating mechanism to stir the water; the water replenishment mechanism is installed on the heating mechanism to quantitatively deliver hot water to the heating network branch; and the detection mechanism is installed on the water replenishment mechanism to detect the temperature and pressure of the heating network branch. Tap water is delivered to the filtration mechanism, and sodium phosphate is added to cause calcium and magnesium ions in the tap water to form insoluble precipitates. The precipitated soft water is then delivered to the heating mechanism for heating. The stirring mechanism is activated to stir the water, accelerating the formation of insoluble precipitates of calcium and magnesium ions in the filtration mechanism, while simultaneously ensuring that the soft water in the heating mechanism is heated evenly. The detection mechanism detects the temperature and pressure of the heating network branch. Hot water heated to a specified temperature in the heating mechanism is delivered to the detection mechanism for replenishment.

[0007] Preferably, the heating mechanism includes a heating base, a heating cylinder, a water inlet pipe, a hinge, a sealing cover, and a handle. The bottom end of the heating base is connected to the ground, and the bottom end of the heating cylinder is connected to the top end of the heating base. The heating cylinder has an internal cavity. The bottom end of the water inlet pipe communicates with the inside of the top end of the heating cylinder. The hinge is installed on the heating cylinder, the sealing cover is installed on the hinge, and the handle is installed on the sealing cover. The water inlet pipe is connected to tap water, which is then delivered to the filtration mechanism. The handle is then pulled to open the sealing cover, and sodium phosphate is injected into the cavity of the heating cylinder. This causes the calcium and magnesium ions in the tap water to form insoluble precipitates, turning the water into soft water, which is then delivered to the cavity of the heating cylinder through the filtration mechanism. The heating base heats the soft water.

[0008] Preferably, the filtration mechanism includes a baffle, an inclined baffle, a connecting pipe, and a valve. The baffle is installed in the cavity of the heating base and divides the cavity into upper and lower parts. The inclined baffle is installed in the upper cavity of the heating base. The connecting pipe is installed on the inclined baffle and communicates with the lower cavity of the heating base. The valve is installed on the connecting pipe. After the calcium and magnesium ions in the tap water precipitate, the valve is opened, and soft water enters below the baffle through the connecting pipe. The inclined baffle prevents the precipitate from entering the connecting pipe.

[0009] Preferably, a filter screen is installed at the connection between the inclined baffle and the connecting pipe; by setting the filter screen, sediment is prevented from entering the connecting pipe, ensuring the water softening effect and preventing impurities from entering the heating network.

[0010] Preferably, the stirring mechanism includes a motor, a reducer, a drive shaft, and multiple sets of stirring rods. The bottom end of the motor is connected to the top end of the heating base, and the bottom end of the reducer is also connected to the top end of the heating base. The drive shaft is rotatably installed in the cavity of the heating base and longitudinally connected to the reducer. All sets of stirring rods are mounted on the drive shaft. When the motor is started, it drives the drive shaft to rotate through the reducer. The drive shaft then drives the multiple sets of stirring rods to rotate. The multiple sets of stirring rods stir the tap water above the partition, accelerating the precipitation of calcium and magnesium ions. At the same time, the multiple sets of stirring rods stir the soft water below the partition, making the soft water heat up more evenly.

[0011] Preferably, the water replenishment mechanism includes a water replenishment pipe, a metering valve, and a check valve. The water replenishment pipe is installed on the heating cylinder and communicates with the interior of the heating cylinder cavity. The metering valve is installed on the water replenishment pipe, and the check valve is installed on the water replenishment pipe. When the operator opens the metering valve, the hot water in the cavity of the heating cylinder is transported to the testing mechanism through the water replenishment pipe for water replenishment. The check valve is used to prevent the hot water in the testing mechanism from flowing back.

[0012] Preferably, the detection mechanism includes a branch pipe, a sleeve, a thermometer, and a pressure gauge. The branch pipe is connected to the heating network, the sleeve is installed on the branch pipe and is connected to the inside of the water supply pipe, the thermometer is installed on the sleeve, and the pressure gauge is installed on the sleeve. Hot water in the water supply pipe is supplied to the branch pipe through the sleeve. The thermometer detects the temperature in the branch pipe, and the pressure gauge detects the pressure in the branch pipe, which facilitates timely water replenishment and temperature adjustment.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: tap water is transported to the filtration mechanism, sodium phosphate is added to cause calcium and magnesium ions in the tap water to form insoluble precipitates, the precipitated soft water is transported to the heating mechanism for heating, the stirring mechanism is activated to stir the water, accelerate the formation of insoluble precipitates of calcium and magnesium ions in the filtration mechanism, and at the same time ensure that the soft water in the heating mechanism is heated evenly, the detection mechanism detects the temperature and pressure of the heating network branches, and the hot water heated to the specified temperature in the heating mechanism is transported to the detection mechanism for replenishment.
