Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figures 1-4 The utility model provides a technical solution: a dosing device for boiler water treatment that can prevent precipitation, comprising: a tank body 1 and a stirring blade 9, a motor 2 is installed on the top of the tank body 1, and a stirring shaft 3 is fixedly connected to the output end of the motor 2.

[0020] The bottom of the tank body 1 is connected to a metering pump 4 through a pipeline, a delivery pipe 5 is fixed to the output end of the metering pump 4, and a feed port 6 is connected to the top of the delivery pipe 5. The bottom of the stirring shaft 3 is fixedly connected to a connecting frame 8, and both ends of the connecting frame 8 are movably connected to stirring blades 9 through a rotating shaft. One end of the stirring blade 9 is fixedly connected to a bevel gear a10, and the outer side of the bevel gear a10 is meshed with a bevel gear b11. A distributing mechanism 12 for uniform feeding is provided on the top of the tank body 1. The bevel gear a10 and the bevel gear b11 form a meshing transmission structure, and the connecting frame 8 forms a rotating structure with the stirring blade 9 through the rotating shaft;

[0021] The bottom of the bevel gear b11 is fixedly connected to the tank body 1 through a connecting shaft, and the end of the stirring blade 9 near the bevel gear a10 is fixedly connected to the support rod 7, and the bottom of the support rod 7 is rollingly connected to the tank body 1 through a ball bearing; the distributing mechanism 12 includes a driving gear 121 fixedly connected to the outer side of the output shaft of the motor 2; the outer side of the driving gear 121 is meshedly connected to the driven gear 122, and the outer side of the driven gear 122 is meshedly connected to the gear ring 123; the outer side of the gear ring 123 is fixedly connected to a distributing disk 124, and the cross-section of the distributing disk 124 is conical, and the inside of the distributing disk 124 is fixedly connected with multiple groups of distributing blades 125, and the distributing blades 125 are inclined; the inner and outer sides of the distributing disk 124 are fixedly connected to the limiting block 13, and the bottom of the limiting block 13 is rollingly connected to the tank body 1 through a ball bearing, the driving gear 121 and the driven gear 122 constitute a meshing transmission structure, and an annular groove is provided on the top of the tank body 1, and the annular groove and the limiting block 13 constitute a sliding structure.

[0022] During specific implementation, when treating the water in the boiler, it is necessary to add chemical agents through the doser to maintain the stability of the water quality. When mixing the agents in the tank body 1, the stirring shaft 3 is driven to rotate by the starting motor 2. When the stirring shaft 3 rotates, the agents inside the tank body 1 can be mixed. At the same time, the stirring shaft 3 will drive the connecting frame 8 to rotate, so that the bevel gear a10 at one end of the stirring blade 9 at the bottom of the connecting frame 8 is engaged with the bevel gear b11, driving the stirring blade 9 to rotate. In this way, when the stirring shaft 3 rotates, the stirring blade 9 can not only rotate with the stirring shaft 3, but also drive the stirring blade 9 to rotate, so as to transport the agents precipitated at the bottom of the tank body 1 to the top, mix with the agents at other positions in the tank body 1, and maintain a uniform concentration of the agents in the tank body 1.

[0023] When feeding the tank body 1, the material is sent into the tank body 1 through the feed port 6, and the material will first enter the distributing mechanism 12, and the motor 2 will drive the driving gear 121 to engage with the driven gear 122 when rotating, so that the driven gear 122 drives the gear ring 123 and the distributing disk 124 to rotate. Since the number of teeth of the driven gear 122 is smaller than that of the gear ring 123, it can drive the gear ring 123 and the distributing disk 124 to perform deceleration motion. When the material enters the rotating distributing disk 124, it can be sprinkled by the internal inclined distributing blades 125, so that the material enters the tank body 1 evenly, completing uniform feeding. The uniform feeding can improve the effect of the doser in mixing the medicine. In this way, the doser can be treated with anti-sedimentation through the above operation, thereby improving the effect of the medicine mixing.

[0024] To sum up: when using a dosing device for boiler water treatment that can prevent precipitation, first, the agent is fed into the feed port 6, and then enters the interior of the tank body 1 through the feed port 6. Then, the motor 2 can be started to drive the stirring shaft 3 to stir and mix the agent inside the tank body 1. After the mixing is completed, the agent can be transported to the boiler through the metering pump 4 and the delivery pipe 5 for water treatment. This is the characteristic of the dosing device for boiler water treatment that can prevent precipitation. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
