[0026] As Figure 1 , Figure 3 shown, the mixing device 4 includes a mixing chamber, the mixing chamber is provided with a water inlet 43 and a first auxiliary material inlet 44, and the mixing device 4 is used to dilute the first auxiliary material. The first auxiliary material inlet 44 is located above the water inlet 43. When dissolving and diluting the first auxiliary material, first quantitatively add water into the mixing chamber through the water inlet 43, then add the first auxiliary material into the mixing chamber through the first auxiliary material inlet 44, and then use the stirring device for stirring.

[0027] The grinding device is connected to the second auxiliary material container 3, and the grinding device is used to grind the second auxiliary material; the first reaction kettle 7 is connected to the carbon source container 1 and the mixing device 4, and the first reaction kettle 7 is used to react the materials stored in the carbon source container 1 with the diluted first auxiliary material; the second reaction kettle 8 is connected to the grinding device and the first reaction kettle 7, and the second reaction kettle 8 is used to produce liquid fertilizer.

The carbon raw material inlet is communicated with the carbon source container 1, and the diluted auxiliary material inlet is communicated with the mixing chamber of the mixing device 4. The diluted first auxiliary material enters the first reaction kettle 7 to react with the carbon raw material, and the reaction product is transported to the second reaction kettle 8. The second auxiliary material is also added to the second reaction kettle 8 to participate in the reaction after being ground by the grinding device. Finally, the second reaction kettle 8 generates liquid fertilizer.

[0029] According to the liquid fertilizer production line of the above embodiment, the mixing device 4 can fully mix water and the first auxiliary material. During the mixing process, water can dissolve some solid components in the first auxiliary material and dilute some liquid components, preventing large pieces of the first auxiliary material from entering the first reaction kettle 7; the grinding device can grind the second auxiliary material with large particle size to the fineness that meets the production requirements, and the ground second auxiliary material enters the second reaction kettle 8; the liquid fertilizer produced by the liquid fertilizer production line has smaller particle size of the auxiliary material and is more evenly mixed, and is not easy to block the fertilization pipeline.

[0030] In some embodiments, as Figure 1 , Figure 2 shown, the grinding device includes a pulverizer 5 and a colloid mill 6. The discharge port of the pulverizer 5 is communicated with the feed port of the colloid mill 6. The pulverizer 5 is used for primary grinding of the second auxiliary material, and the colloid mill 6 is used for secondary grinding of the second auxiliary material after primary grinding.

[0031] Specifically, the pulverizer 5 may include a jaw crusher 51, a storage bin 52, a feeder (not shown in the figure), a main machine 53, an analyzer 54, a collector 55, and a blower 56. The second auxiliary material first enters the jaw crusher 51 for preliminary crushing, and the crushed material enters the storage bin 52. Subsequently, it is conveyed to the main machine 53 through the feeder. The main machine 53 grinds the material, and the ground material is screened by the analyzer 54 to select the material with qualified fineness. Subsequently, the selected material enters the collector 55, and the blower 56 plays a role in conveying the material during the above process.

[0032] The colloid mill 6 may include a rotating tooth and a stationary tooth. The motor drives the rotating tooth to rotate at a high speed. The material ground by the pulverizer 5 enters between the rotating tooth and the stationary tooth and is effectively emulsified, dispersed, homogenized, and pulverized under the action of shear force. After being ground once by the pulverizer 5 and then by the colloid mill 6, the particle size of the second auxiliary material is small, and the liquid fertilizer produced by the liquid fertilizer production line is not likely to block the fertilization pipeline.

[0033] In some embodiments, the finished product mesh number of the pulverizer 5 is 300 - 400 mesh.

[0034] In some embodiments, as Figure 1 shown, the second reaction kettle 8 is provided with a second auxiliary material inlet, which is arranged at the top of the second reaction kettle 8 and is communicated with the grinding device.

[0035] In some embodiments, as Figure 1 shown, the liquid fertilizer production line includes a transfer container 9. The transfer container 9 is provided with a first interface and a second interface. The first interface is communicated with the outlet of the first reaction kettle 7, and the second interface is communicated with the inlet of the second reaction kettle 8. Setting the transfer container 9 can temporarily store the slurry produced by the first reaction kettle 7, and the slurry temporarily stored in the transfer container 9 can be stably supplied to the second reaction kettle 8. In addition, the transfer container 9 can also buffer the slurry produced in the first reaction kettle 7 to prevent the slurry produced in the first reaction kettle 7 from directly impacting the second reaction kettle 8.

[0036] In some embodiments, as Figure 1 、 Figure 3 shown, the mixing device 4 includes a stirring paddle 41 and a driving member 42. The stirring paddle 41 is arranged in the mixing chamber, and the driving member 42 is used to drive the stirring paddle 41 to rotate.

The first auxiliary material solution produced in the mixing chamber can be pumped to the first reaction kettle 7.

[0037] In some embodiments, asFigure 1 As shown in the figure, the liquid fertilizer production line includes a heating unit, which includes a first heating element and a second heating element. The first heating element and the second heating element are respectively arranged in the first reaction kettle 7 and the second reaction kettle 8. Setting the heating unit can heat the slurry in the first reaction kettle 7 and the second reaction kettle 8 to meet the temperature conditions required for the reaction and improve the reaction speed at the same time.

[0038] In some embodiments, such as Figure 1 As shown in the figure, the first heating element is the first heating coil 71, and the second heating element is the second heating coil 81. The first heating coil 71 and the second heating coil 81 have cavities for passing a heat-conducting medium. The contact area between the coil and the slurry is relatively large. When the heat-conducting medium is passed through the cavity, the heat exchange speed between the heat-conducting medium and the slurry is faster, and the heating effect on the slurry is better.

[0039] In other embodiments, the first heating element and the second heating element can also be electric heaters.

[0040] In some embodiments, such as Figure 1 As shown in the figure, the heating unit includes a steam source device 10. The steam source device 10 is connected to the first heating coil 71 and the second heating coil 81, and the steam source device 10 is used to supply steam to the first heating coil 71 and the second heating coil 81.

[0041] In other embodiments, other heat-conducting media, such as heat-conducting oil, can also be provided in the first heating coil 71 and the second heating coil 81.

[0042] In some embodiments, such as Figure 1 As shown in the figure, a first flow valve 72 is arranged on the first heating coil 71, and a second flow valve 82 is arranged on the second heating coil 81. Setting the first flow valve 72 and the second flow valve 82 can respectively adjust the steam flow rates of the first heating coil 71 and the second heating coil 81, and thus facilitate the regulation of the slurry temperatures in the first reaction kettle 7 and the second reaction kettle 8.
