[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] A urea solution preparation system 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0026] like Figure 1 As shown, a urea solution preparation system 100 according to an embodiment of the present invention includes a first storage tank 1 , a transport component 2 and a dissolution tank 3 .

[0027] The first storage tank 1 is used to store urea granules. Figure 1 As shown, the first storage tank 1 is a urea storage tank 4 for storing urea granules.

[0028] The transport assembly 2 includes a transport pipe 21 and a compressor 22. The transport pipe 21 is connected to the first storage tank 1 so that the urea granules in the first storage tank 1 flow into the transport pipe 21. The compressor 22 is used to generate compressed air. The compressor 22 is connected to the transport pipe 21 so that the compressed air flows into the transport pipe 21 to transport the urea granules. Specifically, Figure 1 As shown, the inlet of the transport pipe 21 is connected to the first storage tank 1, so that the urea granules in the first storage tank 1 flow into the transport pipe 21, and the compression member 22 can be compressed to generate compressed air. The compression member 22 can be connected to the transport pipe 21, so that the compressed air flows into the transport pipe 21, and the urea granules are transported by the compressed air.

[0029] The dissolving tank 3 is connected to the transport pipe 21 so that the urea granules in the transport pipe 21 flow into the dissolving tank 3 to dissolve the urea granules into a urea solution. Figure 1 As shown, the inlet of the dissolving tank 3 is connected to the outlet of the transport pipe 21 , and the urea granules in the transport pipe 21 are transported to the dissolving tank 3 through the transport pipe 21 , so that the urea granules are dissolved in the deionized water in the dissolving tank 3 to form a urea solution.

[0030] The urea solution preparation system 100 according to an embodiment of the present invention is provided with a first storage tank 1, a transport assembly 2, and a dissolution tank 3. Urea granules in the first storage tank 1 are transported to the dissolution tank 3 by compressed air. This has high transportation efficiency, saves manpower, reduces transportation costs, and thus reduces the preparation cost of the urea solution preparation system 100.

[0031] In some embodiments, the urea solution preparation system 100 further includes a stirring assembly 31 , a first heating assembly 32 , and an exhaust assembly 11 .

[0032] The stirring assembly 31 is rotatably disposed in the dissolution tank 3 so that the stirring assembly 31 stirs the urea solution in the dissolution tank 3. Specifically, the stirring assembly 31 can be a stirring blade and is rotatably disposed in the dissolution tank 3. The stirring assembly 31 is located at the center of the bottom of the dissolution tank 3 and is driven by a motor to rotate in the dissolution tank 3 to ensure that the urea granules are fully dissolved.

[0033] The first heating assembly 32 is disposed within the dissolution tank 3 and at the bottom of the dissolution tank 3. When the temperature of the dissolution tank 3 falls below a first preset value, the first heating assembly 32 is used to dissolve the urea solution within the tank 3. Specifically, the first heating assembly 32 is a steam coil or an electric heating element disposed at the bottom of the dissolution tank 3. Since urea dissolution is an endothermic process, the first heating assembly 32 must be activated to heat the solution within the dissolution tank 3 to approximately 50°C. When the ambient temperature is too low, the first heating assembly 32 must be activated to raise the solution temperature above 28°C to prevent crystallization of the urea solution.

[0034] An exhaust assembly 11 is provided on and at the top of the first storage tank 1 to exhaust air from the first storage tank 1. Specifically, the exhaust assembly 11 is an axial flow fan or an exhaust fan provided at the top of the first storage tank 1 and connected to the outside through a duct, thereby exhausting air from the first storage tank 1 through the exhaust assembly 11 to prevent urea granules from absorbing moisture and agglomerating.

[0035] In some embodiments, the urea solution preparation system 100 further includes a second storage tank 8, which is disposed on one side of the dissolution tank 3 and communicates with the dissolution tank 3 so that the urea solution in the dissolution tank 3 flows into the second storage tank 8 for storage. Figure 1 As shown, the second storage tank 8 is provided downstream of the dissolution tank 3 , and the inlet of the second storage tank 8 is connected to the outlet of the dissolution tank 3 , so that the urea solution dissolved in the dissolution tank 3 flows into the second storage tank 8 and the urea solution is stored through the storage tank 4 .

[0036] In some embodiments, the urea solution preparation system 100 further includes a connecting pipe 5, the two ends of which are connected to the dissolution tank 3 and the second storage tank 8, respectively, so that the urea solution in the dissolution tank 3 flows into the second storage tank 8 through the connecting pipe 5. Specifically, Figure 1 As shown, the inlet of the connecting pipe 5 is connected to the outlet of the dissolving tank 3 , and the outlet of the connecting pipe 5 is connected to the inlet of the second storage tank 8 , so that the urea solution of the Rong structure flows into the second storage tank 8 through the connecting pipe 5 to store the urea solution.

[0037] In some embodiments, the urea solution preparation system 100 further includes a third heating assembly 6, which surrounds the outer periphery of the connecting pipe 5 so that the third heating assembly 6 heats the urea solution in the connecting pipe 5. Specifically, Figure 1 As shown, the third heating assembly 6 is a steam coil or an electric heating element and the second heating assembly surrounds the outer periphery of the connecting pipe 5, so that the connecting pipe 5 is heated by the second heating assembly to prevent the urea solution from crystallizing during transportation.

[0038] In some embodiments, the urea solution preparation system 100 further includes a second heating assembly disposed at the bottom of the second storage tank 8. When the temperature within the second storage tank 8 is lower than a preset value, the second heating assembly heats the urea solution within the second storage tank 8. Specifically, the second heating assembly is a steam coil or an electric heating element disposed at the bottom of the second storage tank 8 to heat the urea solution within the second storage tank 8 and prevent crystallization of the urea solution during storage.

[0039] In some embodiments, the urea solution preparation system 100 further includes a base having a height of no less than 100 mm, on which the first storage tank 1 is mounted. Specifically, the base can be cast concrete and have a height of no less than 100 mm to ensure that the first storage tank 1 is away from ground moisture, thereby preventing ground moisture from affecting the storage of urea granules.

[0040] In some embodiments, the urea solution preparation system 100 further includes a temperature sensor, a liquid level sensor, and a density sensor.

[0041] A temperature sensor is provided in the dissolution tank 3 to detect the temperature therein. When the temperature in the dissolution tank 3 falls below a predetermined value, the first heating assembly 32 is activated to heat the urea solution. Thus, the temperature in the dissolution tank 3 is detected by the temperature sensor to prevent the urea solution from crystallizing.

[0042] A liquid level sensor is provided in the dissolving tank 3 and is used to detect the urea solution in the dissolving tank 3. Thus, the liquid level in the dissolving tank 3 is detected by the liquid level sensor. When the liquid level in the dissolving tank 3 is low, water and urea granules can be added to the dissolving tank 3 to ensure that the liquid level in the dissolving tank 3 is within the normal liquid level range.

[0043] The density sensor is provided in the dissolving tank 3, and is used to detect the density of the urea solution in the dissolving tank 3. Thus, the density of the urea solution is detected by the density sensor, and the concentration of the urea solution is detected by the density of the urea solution.

[0044] In some embodiments, the urea solution preparation system 100 further includes a circulation pump 7, which is provided on one side of the dissolution tank 3, and one end of the circulation pump 7 is connected to the bottom of the dissolution tank 3 so that the urea solution in the dissolution tank 3 flows into the circulation pump 7, and the other end of the circulation pump 7 is connected to the top of the dissolution tank 3 so that the urea in the circulation pump 7 flows into the dissolution tank 3. Specifically, Figure 1 As shown, the inlet of the circulation pump 7 is connected to the bottom of the dissolution tank 3, and the outlet of the circulation pump 7 is connected to the top of the dissolution tank 3, so that the urea solution circulates through the circulation pump 7 to improve the dissolution efficiency of the urea particles and reduce the dissolution time of the urea.

[0045] In some embodiments, the transport assembly 2 further includes a lifting member, which is disposed in the first storage tank 1. One end of the lifting member is located at the bottom of the first storage tank 1, and the other end of the lifting member cooperates with the transport pipe 21, so that the urea granules in the first storage tank 1 are transported to the transport pipe 21 through the lifting member. Specifically, Figure 1 As shown, the lifting member can be a chain hoist, and the chain hoist is arranged in the first storage tank 1 to transport the urea granules in the first storage tank 1 to the transport pipe 21. The lifting member can continuously lift the urea granules from the storage tank 4 to the transport pipe 21 to ensure the continuity and stability of the entire transportation process.

[0046] In some embodiments, the urea solution preparation system 100 further includes a water storage tank 9 , in which deionized water is stored and which is in communication with the dissolution tank 3 , thereby providing deionized water to the dissolution tank 3 .
