[0005] To solve the above-mentioned technical problems, this utility model provides a heat exchange station water preheating device.

[0006] This utility model discloses a preheating device for water replenishment in a heat exchange station, comprising a preheating tank, support legs, an inlet pipe, an outlet pipe, and electric heating elements. The preheating tank has multiple sets of support legs at its bottom, an inlet pipe at its input end, and an outlet pipe at its output end. Multiple sets of electric heating elements are installed inside the preheating tank. The device also includes a stirring assembly and a dosing assembly. The stirring assembly is located inside the preheating tank, and the dosing assembly is installed at its top. During use, water enters the preheating tank through the inlet pipe. The multiple electric heating elements are activated to heat the water inside the preheating tank. The dosing assembly injects a corrosion and scale inhibitor into the preheating tank. The stirring assembly is then activated, allowing the corrosion and scale inhibitor to mix rapidly with the water while simultaneously enabling the multiple electric heating elements to heat the water evenly and quickly. The heated water is then pumped out through the outlet pipe, improving service life and heating efficiency.

[0007] Preferably, the stirring assembly includes a mounting base, a pump body, a water pumping pipe, a reflux assembly, and a venting assembly. The mounting base is installed on the preheating box, and the pump body is installed on the mounting base. A water pumping pipe is provided at the input end of the pump body, and the input end of the water pumping pipe is connected to the bottom end of the preheating box. A reflux assembly is provided at the output end of the pump body, and a venting assembly is provided on the reflux assembly. When the pump body is started, the water at the bottom of the preheating box is transported to the top of the preheating box through the water pumping pipe and the reflux assembly, thereby allowing the water inside the preheating box to circulate internally. This allows the water to mix quickly with the corrosion and scale inhibitor, while multiple sets of electric heating tubes uniformly and rapidly heat the internally circulated water.

[0008] Preferably, the dosing assembly includes a medicine tank, a delivery pipe, a delivery valve, and a cover plate. The medicine tank is installed at the top of the preheating box, and a cover plate is provided at the top of the medicine tank. A delivery pipe is provided at the output end of the medicine tank, and the output end of the delivery pipe is connected to the top of the preheating box. A delivery valve is installed on the delivery pipe. The medicine tank stores corrosion and scale inhibitors. Opening the delivery valve allows the corrosion and scale inhibitors to be injected into the preheating box through the delivery pipe, completing the dosing and improving convenience.

[0009] Preferably, the reflux assembly includes a reflux pipe, a reflux valve, a hollow disc, L-shaped nozzles, and a rotary joint. A reflux pipe is provided at the pump body output end, extending into the preheating chamber and rotatably connected to the top of the L-shaped nozzles via the rotary joint. Multiple sets of L-shaped nozzles are provided on the outer wall of the hollow disc, and a reflux valve is installed on the reflux pipe. When the pump body is started, water from the bottom of the preheating chamber enters the reflux pipe through the pumping pipe and then enters the hollow disc through the rotary joint. Water inside the hollow disc is sprayed outwards through the multiple sets of L-shaped nozzles. The recoil force of the sprayed water causes the hollow disc to rotate, rapidly mixing the corrosion and scale inhibitor with the water and circulating the water, thereby heating the water through the multiple sets of electric heating elements.

[0010] Preferably, the venting assembly includes a venting pipe and a venting valve. The venting pipe is provided on the return pipe, and the venting valve is installed on the venting pipe. When it is necessary to drain the water inside the preheating tank for maintenance, the return valve is closed, the venting valve is opened, and the pump body is started, so that the water inside the preheating tank is discharged through the venting pipe.

[0011] Preferably, it also includes supports, with a set of supports provided at the bottom of each set of legs; multiple sets of legs and multiple sets of supports work together to provide stable support for the preheating box and improve stability.

[0012] Preferably, it also includes a level gauge, which is installed on the medicine tank; the level gauge displays the level of the corrosion and scale inhibitor inside the medicine tank.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, water enters the preheating box through the inlet pipe, multiple sets of electric heating tubes are activated to heat the water inside the preheating box, the dosing component injects the corrosion and scale inhibitor into the preheating box, and the stirring component is activated, so that the corrosion and scale inhibitor and water are quickly mixed, and the multiple sets of electric heating tubes heat the water evenly and quickly. The heated water is then pumped out through the outlet pipe, which improves the service life and heating efficiency. Attached Figure Description
