[0022] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0023] Example 1:

[0024] A boiler dosing device, such as Figure 1 It includes a reagent tank assembly 1, a stirring assembly 2, and a pump assembly 4.

[0025] In this embodiment, the medicine box group 1 includes two medicine boxes, namely the upper medicine box 11 and the lower medicine box 12. If three kinds of medicine are needed, three medicine boxes can be set. The two medicine boxes are stacked in the height direction. A connecting structure can be set between the two medicine boxes to ensure the integrity. At the same time, in order to ensure stability, a steel structure support 6 is set, and the support 6 is connected to the medicine box.

[0026] like Figure 4 The stirring assembly 2 includes a stirring motor 21, a stirring shaft 22 connected to the stirring motor 21, and a stirring blade 23 connected to the stirring shaft 22. The stirring motor 21 is installed on the upper reagent tank 11 and is connected to the stirring shaft through a reduction module. The stirring shaft 22 extends from the upper reagent tank 11 to the lower reagent tank 12. Waterproof seals should be provided at both the position where the stirring shaft 22 passes through and enters the reagent tank. The stirring blade 23 is provided in all reagent tanks.

[0027] The above structural design allows multiple medicine tanks to be stacked in the height direction, thus solving the problem of large area occupation caused by the traditional side-by-side arrangement of medicine tanks. In addition, multiple medicine tanks can share the stirring components, eliminating the need to set up multiple sets of stirring components and saving costs.

[0028] Pump assembly 4 is connected to the chemical tank and is used to add the chemicals in the chemical tank to the boiler.

[0029] In this embodiment, a set of pump body assemblies 4 is provided, and all medicine tanks are connected to the pump body assembly 4. The pump body assembly 4 includes a valve body 43, a metering pump 41, and a medicine outlet 42. Figure 2 Each chemical tank is equipped with a corresponding valve body 43. When adding chemicals, the corresponding valve body 43 is opened, and the chemical solution is pumped into the boiler through the chemical solution outlet 42 by the metering pump 41.

[0030] The boiler dosing device also includes a chemical addition structure 3, which includes a dosing port 34 on the top chemical tank, a dosing pipe connected to the dosing port 34, and a cover 31 installed on the dosing port 34. The number of dosing pipes is the same as the number of chemical tanks, and each chemical tank is connected to a dosing pipe.

Pipe 1 33 connects to the upper medicine tank 11, and pipe 2 32 extends into the lower medicine tank 12. When adding medicine to the medicine tank, the medicine is added to the corresponding dosing pipe. Traditionally, adding medicine to medicine tanks placed side by side requires workers to walk to each medicine tank to add medicine. This solution can complete the dosing operation of multiple medicine tanks at one dosing port 34, improving efficiency.

[0032] Preferably, such as Figure 5 Each dosing tube has a flip cover 36 at its outer end opening. The flip cover 36 has an identification area 35 for marking the name of the medicine to avoid adding the wrong medicine. When adding medicine, first unscrew the cap 31, and then flip open the corresponding flip cover 36 to add the medicine.
