[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] Depend on Figure 1 and Figure 2 As shown, this is a schematic diagram of the structure of the dust removal and gas scrubbing box of the compound fertilizer granulation tower in this embodiment. It includes a processing box 1, a conical top plate 2 and a conveying component 3. The processing box 1 is installed as a whole at the top of the granulation tower. The conveying component 3 connected to the exhaust port of the granulation tower is installed inside the processing box 1. The conical top plate 2 is installed at the top of the processing box 1. A spraying mechanism 4 for treating the exhaust gas discharged from the granulation tower is installed inside the processing box 1.

[0026] During use, the entire equipment is installed at the top of the granulation tower, and the conveyor 3 is connected to the exhaust port of the granulation tower through the cooperation of the conveyor 3, so that the exhaust gas discharged from the granulation tower can stably enter the processing box 1. The exhaust gas entering the processing box 1 is dusted and cleaned by the operation of the spray mechanism 4, and the particulate compound fertilizer dust mixed in the exhaust gas is treated to achieve secondary filtration of the exhaust gas, thus ensuring the stability of the equipment during operation.

[0027] From the appendix Figure 3As shown, this is a schematic diagram of the spraying mechanism 4 in this embodiment. The spraying mechanism 4 includes a delivery pump 41, a connecting pipe 42, a curved pipe 43, and a spraying component 44. The delivery pump 41 is installed on the side of the processing box 1. The connecting pipe 42 is installed at the output end and the input end of the delivery pump 41, respectively. There are two sets of connecting pipes 42. The curved pipe 43 is connected to the end of one set of connecting pipes 42. The spraying component 44 is installed on the inner wall of the conical top plate 2 and is connected to the curved pipe 43.

[0028] During use, a certain amount of water is stored inside the processing box 1. The water is extracted from the processing box 1 by the operation of the delivery pump 41, and then the water enters the spray component 44 through the curved pipe 43. The spray component 44 is used to treat the exhaust gas inside the processing box 1 and the conical top plate 2 to reduce dust.

[0029] From the appendix Figure 3 As shown, the spray component 44 consists of a cross bracket and multiple sets of atomizing nozzles. The cross bracket is installed inside the conical top plate 2, and the atomizing nozzles are installed at equal intervals at the bottom of the cross bracket. In use, the design of the cross bracket and multiple sets of atomizing nozzles expands the spraying range of the nozzles themselves and ensures the stability of the equipment during operation.

[0030] From the appendix Figure 4 As shown, the spraying mechanism 4 also includes a dividing plate 45 and a filter plate 46. The dividing plate 45 is fixedly installed inside the processing box 1, and the filter plate 46 is installed between the dividing plate 45 and the inner wall of the processing box 1.

[0031] During use, the dividing plate 45 divides the internal space of the processing box 1. The water source falling from the upper spray will fall between the processing box 1 and the dividing plate 45. When the water level exceeds the dividing plate 45, the water source will automatically pass through the filter screen plate 46 under the action of gravity and enter the space on the side of the dividing plate 45 to filter the water source, which is convenient for the subsequent delivery pump 41 to circulate the water source.

[0032] From the appendix Figure 3 As shown, the curved tube 43 is Z-shaped, and the bottom end of the curved tube 43 is in contact with the outer surface of the conical top plate 2. During use, after the water source is sprayed multiple times, the water source temperature will gradually rise. The shape of the curved tube 43 itself can extend the water source transportation path. By utilizing the height of the granulation tower itself and the external wind force, the water source inside the curved tube 43 can be cooled.

[0033] From the appendix Figure 5 As shown, it is a structural schematic diagram of the conveying component 3 in this embodiment. The conveying component 3 includes a conveying pipe 31 and a connecting groove 32. The conveying pipe 31 is installed on the inner wall surface of the processing box 1. The conveying pipe 31 and the interior of the processing box 1 are provided with a connecting groove 32 that communicates with the exhaust port of the granulation tower.

[0034] During use, the opening of the connecting groove 32 facilitates the entry of the exhaust gas discharged from the granulation tower into the processing box 1. The height of the pipe wall of the conveying pipe 31 can prevent the water source stored inside the processing box 1 from entering the conveying pipe 31. Subsequently, the water source wraps around the outer wall of the conveying pipe 31 to perform preliminary cooling treatment on the exhaust gas.

[0035] From the appendix Figure 5 As shown, this is a structural schematic diagram of the conveying component 3 in this embodiment. The conveying component 3 also includes a support rod 33 and a protective top cover 34. The support rod 33 is fixedly installed at equal intervals on the upper surface of the conveying pipe 31, and the protective top cover 34 is installed on the top of the support rod 33. During use, the installation of the protective top cover 34 blocks the opening at the top of the conveying pipe 31, preventing the water sprayed by the spraying component 44 from directly entering the interior of the conveying pipe 31. The conveying pipe 31 can guide the conveyed exhaust gas to spray out to both sides, which is convenient for subsequent spraying treatment.

[0036] From the appendix Figure 2 As shown, an extraction fan 5 is installed at the top opening of the conical top plate 2. During use, the extraction fan 5 can guide the exhaust gas inside the processing box 1 for transportation and extraction, so that the exhaust gas can be stably discharged from the processing box 1.

[0037] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
