[0025] Reference Figures 1-4 A crystallization device for producing humic acid-containing water-soluble fertilizer includes an evaporator 1, a combustion chamber 2 fixedly installed on the top surface of the evaporator 1, and a heat recovery component disposed on the top surface of the evaporator 1 for heat recovery. The heat recovery component includes a heat exchange tank 3 disposed on the top surface of the evaporator 1. The top surfaces of the evaporator 1 and the heat exchange tank 3 are respectively provided with first circular through holes. A first connecting pipe 5 is fixedly sleeved on the inner wall of the first circular through hole. Two partitions 4 and a plurality of spiral heat exchange tubes 22 are fixedly sleeved on the inner wall of the heat exchange tank 3. A plurality of support holes 24 are provided on the top surface of the partitions 4, and the support holes 24 are fixedly connected to the spiral heat exchange tubes 22. The heat exchange tank 3 has two second circular through holes on its outer circular wall. The first circular through hole on the right is fixedly fitted with a second connecting pipe 6, and the second circular through hole on the left is fixedly fitted with a second fixing pipe 10. The outer circular wall of the second connecting pipe 6 is fixedly fitted with a circulation pump 7, and the inner circular wall of the outlet of the circulation pump 7 is fixedly fitted with a first fixing pipe 8. The outer circular wall of the evaporator 1 has two third circular through holes. The inner circular wall of the evaporator 1 is fixedly fitted with a spiral pipe 9, which is fixedly fitted with the third circular through holes, the first fixing pipe 8, and the second fixing pipe 10. The evaporation assembly is used to evaporate water.

[0026] In use, the water vapor generated by evaporation enters the heat exchange tank 3 through the first connecting pipe 5 and then enters several spiral heat exchange tubes 22. The space between the two partitions 4 is filled with heat-conducting liquid. The steam spirals upward along the inner wall of the spiral heat exchange tubes 22, releasing heat and heating the spiral heat exchange tubes 22. Some of the steam is discharged upward, and the other part is condensed and discharged from the heat exchange tank 3 through the condensate pipe 15. The heat-conducting liquid is indirectly heated by the water vapor, allowing the heat-conducting liquid to temporarily store heat. When new humic acid-containing water-soluble fertilizer is added, the temperature of the material is detected by the temperature detector 11. When the temperature is low, the circulation pump 7 is started to circulate the heat-conducting liquid in the loop formed by the partitions 4, the second connecting pipe 6, the spiral tubes 9, and the second fixed pipe 10. The circulating heat-conducting liquid preheats the new material, reducing the fuel consumption of the burner 12.

[0027] In this embodiment, the evaporation assembly includes: a plurality of heat-conducting plates 13, all of which are fixedly installed on the bottom surface of the evaporator tank 1; a fourth circular through hole is opened on the outer circular wall of the combustion chamber 2; a burner 12 is fixedly sleeved on the inner circular wall of the fourth circular through hole; an exhaust pipe 14 is connected through the outer circular wall of the combustion chamber 2; a threaded hole is opened on the outer circular wall of the evaporator tank 1; a temperature detector 11 is threadedly connected to the inner circular wall of the threaded hole; a fourth circular through hole is opened on the outer circular wall of the heat exchange tank 3; a condensate pipe 15 is fixedly sleeved on the inner circular wall of the fourth circular through hole; a fixing hole 25 is opened on the outer circular wall of the heat exchange tank 3; a water supply pipe 16 is fixedly sleeved on the inner circular wall of the fixing hole 25; and a float valve 17 is fixedly sleeved on the inner circular wall of the water supply pipe 16.

[0028] In use, the burner 12 is activated to heat the bottom of the evaporator 1. Several heat-conducting plates 13 increase the heat absorption area and conduct heat to the bottom of the evaporator 1, thereby heating the humic acid-containing water-soluble fertilizer inside the evaporator 1, promoting water evaporation, and gradually crystallizing the humic acid-containing water-soluble fertilizer to achieve the water evaporation process. The float valve 17 is connected to the water supply pipe 16. When the liquid level is lower than the detection position, the float valve 17 can automatically replenish the liquid, eliminating the need for manual operation.

[0029] In this embodiment, a fixed cover 18 is fixedly installed on the top surface of the heat exchange tank 3, and several support plates 23 are fixedly installed on the top surface of the evaporator 1. The support plates 23 are fixedly installed with the heat exchange tank 3. The circulating pump 7 is fixedly installed with the top surface of the evaporator 1. A support frame 19 is fixedly installed on the outer circular wall of the evaporator 1. A PLC controller is fixedly installed on one side of the support frame 19. The circulating pump 7 and the temperature detector 11 are electrically connected to the PLC controller. A discharge valve pipe 21 is fixedly sleeved on the inner circular wall of the outlet of the evaporator 1. The discharge valve pipe 21 refers to the discharge pipe and the discharge valve connected together as a whole. A feed pipe 20 is fixedly sleeved on the inner circular wall of the inlet of the evaporator 1.

[0030] When in use, the temperature detector 11 can monitor the material temperature in real time, intelligently adjust the heating power of the burner 12 and start the heat transfer fluid preheating function.

[0031] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: When the user needs to heat the humic acid-containing water-soluble fertilizer to separate water, the humic acid-containing water-soluble fertilizer is fed into the evaporator 1 through the feed pipe 20. The burner 12 is activated to heat the bottom of the evaporator 1. Several heat-conducting plates 13 increase the heat absorption area and conduct heat to the bottom surface of the evaporator 1, thereby heating the humic acid-containing water-soluble fertilizer inside the evaporator 1, promoting water evaporation, and gradually crystallizing the humic acid-containing water-soluble fertilizer, thus realizing the water evaporation process. The water vapor generated by evaporation enters the heat exchange tank 3 through the first connecting pipe 5 and enters several spiral heat exchange tubes 22. The space between the two partitions 4 is filled with a heat-conducting liquid. Steam spirals upwards along the inner wall of the spiral heat exchange tube 22, releasing heat and heating the tube. Part of the steam is discharged upwards, while the other part condenses and is discharged from the heat exchange tank 3 through the condensate pipe 15. The steam heats the heat transfer fluid, allowing it to temporarily store heat. When new humic acid-containing water-soluble fertilizer is added, the material temperature is detected by the temperature detector 11. When the temperature is low, the circulation pump 7 is started to circulate the heat transfer fluid in the loop formed by the partition 4, the second connecting pipe 6, the spiral tube 9, and the second fixed pipe 10. The circulating heat transfer fluid preheats the new material, reducing the fuel consumption of the burner 12. This achieves the effect of heat energy recovery from the steam generated when heating the humic acid-containing water-soluble fertilizer. The recovered heat energy is used to preheat the newly added humic acid water, reducing fuel consumption and saving energy, making it quite practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
