[0028] The spray assembly 2 includes a granulation liquid tank 201, a liquid filling port 202 is arranged on the top surface of the granulation liquid tank 201, a liquid infusion tube 206 is connected to the side wall of the granulation liquid tank 201, a support frame 203 is arranged on the side of the granulation liquid tank 201, a switch 204 and a water pump 205 are arranged on the top surface of the support frame 203, the power output end of the switch 204 is electrically connected to the water pump 205, the output end of the water pump 205 is connected to the liquid infusion tube 207, the body of the liquid infusion tube 207 passes through the side wall of the fluidized bed box 1, the output end of the liquid infusion tube 207 is connected to the liquid infusion elbow 208, and the output end of the liquid infusion elbow 208 is connected to a plurality of spray heads 209;

[0029] The heat flow component 3 includes a fan 301, the power output end of the switch 2 400 is electrically connected to the fan 301, the output end of the fan 301 is connected to the main air duct 303, the output end of the main air duct 303 is connected to multiple branch air ducts 304, and the output end of the branch air duct 304 is connected to the inside of the heat flow chamber 101;

[0030] In the embodiment of the present utility model, the operation of the fan 301 is controlled by the switch 2 400, and the airflow of the fan 301 is transported to the main air duct 303 through the output end, and the main air duct 303 transports the airflow to the four branch air ducts 304, and the four branch air ducts 304 transport the airflow to the four heat flow bins 101 inside the fluidized bed box 1, and the heating tubes 102 in the four heat flow bins 101 are further controlled by the switch 2 400 to heat and generate high temperature, and the airflow generates a hot air flow due to the high temperature effect of the heating tubes 102, and the airflow is continuously transported by the fan 301, so that the hot air flow moves upward from the four heat flow bins 101 and is discharged from the four exhaust pipes 106, forming a continuous upward hot air flow inside the fluidized bed box 1, and small particle raw materials are added to the interior of the fluidized bed box 1 through the feed port 105. Under the action of the continuous upward hot air flow, the small particle raw materials are lifted by the hot air flow to form a fluidized state, just like boiling. Further, the water pump 205 is controlled to work through the switch 204, and the water pump 205 transports the granulation liquid in the granulation liquid box 201 to the infusion tube 2 207 through the infusion tube 206, and further transports it to the infusion elbow 208, and sprays the granulation liquid through multiple spray heads 209 to form a mist. After these mist-like granular liquids come into contact with the small-particle raw materials, they adhere to each other and gradually form larger and larger large-particle nest materials. At the same time, the hot air flow continuously exchanges heat with the large-particle nest materials, taking away the moisture in the large-particle nest materials to achieve the purpose of drying. As the drying proceeds, the large-particle nest materials gradually reach the specified degree of dryness. By designing the infusion elbow 208, the granulation liquid can be more evenly filled in the entire boiling bed box 1, thereby improving the degree of full contact between the boiling small-particle raw materials and the granulation liquid, which is conducive to rapid bonding to form large-particle nest material products, greatly improving production efficiency.

[0031] Specifically, a steel mesh 107 is provided at the bottom of the exhaust pipe 106, and a steel mesh 2 108 is provided at the top of the exhaust pipe 106. The function of the steel mesh 107 is to prevent small particles of raw materials from boiling into the exhaust pipe 106, and the function of the steel mesh 2 108 is to prevent external impurities from entering the exhaust pipe 106.

[0032] Furthermore, the bottom of the fan 301 is screwed to a base 302 , and the base 302 is fixed to the ground by bolts, thereby enhancing the stability of the fixing structure of the fan 301 .

[0033] It is worth noting that the cross-section of the top of the fluidized bed box 1 is a trapezoidal structure, and six diverter plates 109 are arranged on the top of the fluidized bed box 1. The six diverter plates 109 can guide the hot air flow more evenly into the exhaust pipe 106, so that the hot air flow has a better boiling effect on the small particle raw materials, further improving the production efficiency.

[0034] It is worth noting that the infusion elbow 208 is arranged on the inner wall of the boiling bed box 1. The infusion elbow 208 has a corrugated structure. The corrugated structure allows multiple spray heads 209 to be evenly dispersed on the inner wall of the boiling bed box 1. When the spray head 209 sprays the mist granulation liquid, the spraying range is more comprehensive, which can make the granulation liquid evenly distributed on each small particle raw material to the greatest extent, thereby enhancing the granulation effect and improving production efficiency.

[0035] It is worth mentioning that the side wall of the bed bottom plate 103 is connected to the inner wall of the boiling bed box 1, and the other side wall of the bed bottom plate 103 is connected to the discharge port 104. The bed bottom plate 103 is inclined at a 30-degree angle in the horizontal direction. A plurality of air holes are provided on the top surface of the bed bottom plate 103.

[0036] Working principle: This embodiment provides a horizontal square fluidized bed granulating dryer. When in use, the fan 301 is controlled to work through the switch 2 400. The airflow of the fan 301 is transported to the main air duct 303 through the output end. The main air duct 303 transports the airflow to the four branch air ducts 304. The four branch air ducts 304 transport the airflow to the four heat flow bins 101 inside the fluidized bed box 1. The heating tubes 102 in the four heat flow bins 101 are further controlled by the switch 2 400 to heat and generate high temperature. The airflow generates a hot air flow through the high temperature effect of the heating tubes 102. The airflow is continuously transported by the fan 301, so that the hot air flow moves upward from the four heat flow bins 101 and is discharged from the four exhaust pipes 106, forming a continuous upward hot air flow inside the fluidized bed box 1. The small particle raw materials are added to the interior of the fluidized bed box 1 through the feed port 105. In the continuous upward hot air Under the action of the flow, the small-particle raw materials are lifted up by the hot air flow to form a fluidized state, just like boiling. Further, the water pump 205 is controlled to work through the switch 204. The water pump 205 transports the granulating liquid in the granulating liquid tank 201 through the infusion tube 206 to the infusion tube 207, and further transports it to the infusion elbow 208, and sprays the granulating liquid through multiple spray heads 209 to form a mist. After these mist-like granular liquids come into contact with the small-particle raw materials, they adhere to each other and gradually form larger and larger large-particle nests. At the same time, the hot air flow continuously exchanges heat with the large-particle nests, taking away the moisture in the large-particle nests to achieve the purpose of drying. As the drying proceeds, the large-particle nests gradually reach the specified degree of dryness. After the small-particle raw materials are formed by the granulation work, they fall on the bed bottom plate 103 and slide through the bed bottom plate 103 to the lower discharge port 104.
