The dosing cylinder 403 serves as a transfer container for the softening agent. It has a transparent structure and graduations on its outer wall to facilitate the determination of its internal capacity for quantitative delivery. The valve pipe 404 is equipped with a valve to facilitate the delivery of the agent inside the dosing cylinder 403 into the inlet pipe 501 when water is being supplied.

[0019] like Figure 1 and Figure 3As shown, a water inlet assembly 5 is installed on the upper side of one side of the softening treatment tank 1. The water inlet assembly 5 includes an inlet pipe 501 and a spiral guide plate 502. The inlet pipe 501 is fixedly connected to the softening treatment tank 1, and the spiral guide plate 502 is fixed to the inner wall of the inlet pipe 501. The water inlet assembly 5 also includes an annular box 503, a connecting pipe 504, and a water delivery pipe 505. The annular box 503 is fixed to the upper outer side of the inlet pipe 501, and the inner side of the annular box 503 near the inlet pipe 501... The wall is fixed with connecting pipes 504 in an array, and a water supply pipe 505 is connected to the outside of the annular box 503. The water supply pipe 505 facilitates the delivery of boiler water into the interior of the annular box 503, so that the water flow is delivered into the interior of the liquid inlet pipe 501 through the array of connecting pipes 504. The inner wall of the liquid inlet pipe 501 is provided with a spiral guide plate 502, which can play a guiding role, so that the softening agent can be initially mixed with the boiler water when it is introduced, thereby improving the subsequent mixing efficiency.

[0020] like Figures 2-3 As shown, a stirring assembly 6 is installed in the middle of the softening treatment tank 1. The stirring assembly 6 includes a drive motor 601, a stirring shaft 602, and a stirring blade 603.

The drive motor 601 and the stirring shaft 602 facilitate the rotation of the stirring blade 603, thereby promoting the full mixing of boiler water and softening agent in the softening treatment tank 1 to achieve softening of boiler water.

[0021] like Figures 2-3 As shown, a filter assembly 7 is installed inside the filter box 2. The filter assembly 7 includes a first filter screen 701, a first drain pipe 702, a second filter screen 703, and a second drain pipe 704. The first filter screen 701 and the second filter screen 703 are fixed inside the filter box 2 from top to bottom. The first drain pipe 702 is connected to the lower middle part of the first filter screen 701, and the second drain pipe 704 is connected to the lower middle part of the second filter screen 703. A sludge collection box 8 is threaded to the bottom of the second drain pipe 704. Both the first filter screen 701 and the second filter screen 703 have a funnel-shaped structure. The first drain pipe 702... Both the first and second drain pipes 704 have a hollow structure. The first drain pipe 702 is located in the middle of the second drain pipe 704, and the first drain pipe 702 and the second drain pipe 704 have a concentric circular structure. The first filter screen 701 and the second filter screen 703, which have a funnel-shaped structure, facilitate secondary filtration of the boiler water inside the filter box 2. The impurities after the two filtrations enter the first drain pipe 702 and the second drain pipe 704 under the action of gravity and water flow, and finally settle into the sludge collection box 8 on the lower side. The sludge collection box 8 is sealed and screwed to the bottom of the second drain pipe 704, so it is easy to disassemble and clean the impurities inside.

[0022] In summary, as Figures 1-3 As shown, in use, the boiler feed water softening device first uses a metering pump 401 and a delivery pipe 402 to send the softening agent from the agent tank 3 into the dosage cylinder 403, making the dosage cylinder 403 a transfer container for the softening agent. Then, boiler water is sent into the annular box 503 through the water delivery pipe 505, and the water flows through the array of connecting pipes 504 into the inlet pipe 501. The valve pipe 404, equipped with a valve, allows the agent from the dosage cylinder 403 to be sent into the inlet pipe 501 during water intake. The inner wall of the inlet pipe 501 is equipped with a spiral guide plate 502, which guides the flow, allowing the softening agent to initially mix with the boiler water during intake, thereby improving subsequent mixing efficiency. The drive motor 601 and the stirring shaft 602 drive the stirring blades 603 to rotate, thereby promoting the full mixing of boiler water and softening agent in the softening treatment box 1 to achieve boiler water softening. After mixing, the valve of the drain pipe 9 is opened to allow the boiler water to enter the filter box 2. At this time, the first filter screen 701 and the second filter screen 703, which have a funnel-shaped structure, can perform secondary filtration on the boiler water inside the filter box 2. The impurities after the two filtrations enter the first drain pipe 702 and the second drain pipe 704 under the action of gravity and water flow, and finally settle into the sludge collection box 8 at the bottom. The sludge collection box 8 is sealed and screwed to the bottom of the second drain pipe 704, so it is easy to disassemble and clean the impurities inside. This completes the use process of the boiler water softening device.
