[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides a phosphate fertilizer packaging agent production blending tank, such as Figure 1-Figure 3 As shown, it includes a tank body 20, a first coil 1 and a second coil 3 are arranged inside the tank body 20, a set of bottom coils 5 are arranged at the bottom of the tank body 20, a first feed port 11 and a second feed port 16 are arranged on both sides of the top of the tank body 20, a first stirring paddle 2 is arranged in the middle of the first coil 1, and a second stirring paddle 4 is arranged inside the second coil 3, and a first blending material outlet 8, a second blending material outlet 9 and a third blending material outlet 10 are arranged on the outer wall of one side of the tank body 20 from bottom to top.

[0021] In this embodiment, the first coil 1 and the second coil 3 are spiral structures arranged from bottom to top, a first coil heat medium inlet 7 is provided on the bottom side of the first coil 1, a second coil heat medium inlet 17 is provided on the bottom side of the second coil 3, a first coil heat medium outlet 13 is provided on the top side of the first coil 1, and a second coil heat medium outlet 14 is provided on the top side of the second coil 3, so as to facilitate the entry and discharge of the heating medium.

[0022] Specifically, the bottom coil 5 is a horizontally arranged corrugated coil, one end of the bottom coil 5 is provided with a bottom coil heat medium inlet 6, and the other end of the bottom coil 5 is provided with a bottom coil heat medium outlet 18 for the entry and discharge of the heat medium.

[0023] Furthermore, the top of the first stirring paddle 2 is driven by the first stirring motor 12, and the top of the second stirring paddle 4 is driven by the second stirring motor 15. The bases of the first stirring motor 12 and the second stirring motor 15 are fixed on the top of the tank body 20 to facilitate stable stirring action.

[0024] Furthermore, the first blending material outlet 8, the second blending material outlet 9 and the third blending material outlet 10 are arranged at equal intervals from bottom to top to ensure discharge of materials at different heights.

[0025] Furthermore, a thermometer 19 is provided in the middle of the tank body 20 for monitoring the temperature inside the tank body 20 .

[0026] Furthermore, a plurality of positioning hooks 21 are installed on the inner wall of the trough body 20, and the first coil 1 and the second coil 3 are clamped at the positioning hooks 21. Two parallel fixing rods 22 are installed at the bottom of the trough body 20, and positioning buckles 23 are installed on the fixing rods 22. The bottom coil 5 is clamped on the positioning buckles 23, which facilitates the respective fixation of the first coil 1, the second coil 3 and the bottom coil 5. The outer ends of the bottom coil heat medium inlet 6 and the bottom coil heat medium outlet 18 are installed with connecting pipes 51, which are convenient for external connection of heating pipelines.

[0027] When the phosphate fertilizer coating production blending tank of the utility model is in use, the tank body uses the first coil 1, the second coil 3 and the bottom coil 5 to uniformly heat the phosphate fertilizer coating raw material, and at the same time, the first stirring paddle 2 and the second stirring paddle 4 are used to efficiently mix and stir, so as to ensure that the raw materials are fully mixed and reach the desired viscosity and fluidity. The heating medium (such as steam) is input into the first coil 1 and the second coil 3 through the first coil heat medium inlet 7 and the second coil heat medium inlet 17. At the same time, the heating medium is input into the bottom coil 5 through the bottom coil heat medium inlet 6.

[0028] The heating medium flows in the coil and transfers heat to the raw materials of the phosphate fertilizer coating in the tank. The spiral structure design of the first coil 1 and the second coil 3, as well as the corrugated design of the bottom coil 5, ensures uniform distribution and efficient transfer of heat. When the heating temperature reaches the set constant target value, the raw materials of the phosphate fertilizer coating are respectively added through the first feed port 11 and the second feed port 16. The first stirring motor 12 drives the first stirring paddle 2, and the second stirring motor 15 drives the second stirring paddle 4 to fully stir the raw materials in the tank.

[0029] The design of the stirring paddle ensures that the raw materials are evenly mixed in the tank body, and cooperates with the heating coil to reduce the viscosity of the raw materials and improve fluidity. The evenly mixed phosphate fertilizer package is discharged in sequence through the first blending material outlet 8, the second blending material outlet 9 and the third blending material outlet 10. These outlets are arranged at equal intervals from bottom to top to ensure that materials at different heights can be discharged evenly.

[0030] After the production is completed, all the heat medium inlets (the first coil heat medium inlet 7, the second coil heat medium inlet 17, and the bottom coil heat medium inlet 6) are closed to stop heating. At the same time, the first stirring motor 12 and the second stirring motor 15 are stopped to end the stirring process. Through this design and working principle, the tank body can achieve efficient and uniform heating and mixing effects, and improve the production efficiency and quality of the phosphate fertilizer coating agent.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
