[0032] By putting the raw materials into the inside of the fluidization assembly 1, at this time the inclined air blowing assembly 2 can be inclined to blow the raw materials in the inside of the fluidization assembly 1 upwards, so that the raw materials can be constantly moved to the discharge assembly 3, and at the same time the liquid spraying assembly 4 can spray the granulation liquid to the outer surface of the raw materials which are constantly moving, so that the raw materials can form granular products, and when the products move to the discharge assembly 3, the rotating end of the discharge assembly 3 can drive the products to rotate, so that the products directly fall from the inside of the fluidization assembly 1.

[0033] By continuously inclining the raw materials in the inside of the fluidization assembly 1 through the inclined air blowing assembly 2, the raw materials are constantly moved to the discharge assembly 3 while being fluidized. At the same time, the liquid spraying assembly 4 can spray the granulation liquid to the outer surface of the raw materials which are constantly moving, so that the raw materials can form granular products. The above arrangement enables the raw materials to constantly move in the inside of the fluidization assembly 1, avoiding the situation that the raw materials are wrapped with too much granulation liquid on the surface due to staying in the inside of the fluidization assembly 1 for too long time, so that the overall size of the products produced can be kept consistent.

[0034] In an embodiment, for the above-mentioned fluidization assembly 1, the fluidization assembly 1 comprises a barrel 101, one side of the barrel 101 is fixedly connected with a feeding pipe 102, the inner wall bottom of the barrel 101 is fixedly connected with an airflow distribution plate 103, and the airflow distribution plate 103 is integrally inclined.

[0036] In an embodiment, for the above-mentioned inclined air blowing assembly 2, the inclined air blowing assembly 2 comprises a mounting box 201, the barrel 101 is fixedly installed on the top of the mounting box 201, the inner wall of the mounting box 201 is fixedly connected with a partition plate 202, the partition plate 202 is integrally inclined, a plurality of partition plates 202 are arrayed in the inside of the mounting box 201, a plurality of airflow holes 203 are formed in the inner wall bottom of the mounting box 201 corresponding to the partition plate 202, a shunt box 204 is fixedly connected to the bottom of the mounting box 201, and an airflow pipe 205 is fixedly connected to one side of the shunt box 204.

[0038] In one embodiment, for the above-mentioned discharging assembly 3, the discharging assembly 3 comprises a mounting groove 301 opened on the other side of the barrel 101, an arc-shaped shell 302 fixedly installed inside the mounting groove 301, a rotating shaft 303 rotationally connected inside the arc-shaped shell 302, a discharging plate 304 fixedly connected to the outer surface of the rotating shaft 303, a plurality of discharging plates 304 arranged in a circular array, a motor 305 fixedly installed on the outer surface of the barrel 101, an output end of the motor 305 fixedly connected with the rotating shaft 303, and a discharging hopper 306 fixedly connected to the bottom end of the arc-shaped shell 302.

[0039] The granular product in the barrel 101 wrapped by the granulation liquid can float to the bottom of the discharging plate 304 under the blowing of the inclined air flow, at this time, the motor 305 can drive the plurality of discharging plates 304 to rotate upward through the rotating shaft 303, and the discharging plate 304 continuously rotating upward can drive the product to rotate upward together, when the adjacent discharging plates 304 rotate from the mounting groove 301 to the outside of the barrel 101 and the opening is inclined downward, the product between the discharging plates 304 can roll downward under the action of its own gravity and directly fall into the discharging hopper 306, and the product in the discharging hopper 306 can directly fall to the outside of the barrel 101 under the guidance of the discharging hopper 306; the granular product is easily directly attached to the inner wall of the barrel 101 under the blowing of the inclined air flow, once the product is attached to the inner wall, it is extremely likely to cause accumulation, blockage and other problems, which seriously affects the normal discharge of the product, and even may cause the entire production process to be forced to stop, which is quite troublesome and time-consuming to clean up. The discharging plate 304 arranged to continuously rotate and unload the product can effectively avoid the problem that the product directly contacts and accumulates on the inner wall of the barrel 101 under the blowing of the inclined air flow, ensuring the smoothness and continuity of the product discharge process, so that the product can be stably and normally discharged from the inside of the barrel 101, greatly improving the production efficiency and reducing many production risks and additional maintenance costs caused by poor discharging.

[0041] One end of the conveying pipe 401 is connected with a container outside the barrel 101 for containing granulation liquid. When the raw materials move in the interior of the barrel 101 under the blowing of the inclined gas flow, the granulation liquid can be directly shunted into the interiors of the shunt pipes 402 through the conveying pipe 401, and the granulation liquid in the interiors of the shunt pipes 402 can be directly sprayed onto the outer surfaces of the raw materials in constant movement through the spray heads 403, so that the granulation liquid can be wrapped on the outer surfaces of the raw materials. When the conveying pipe 401 and the gas flow distribution plate 103 have the same inclination, when the gas flows upward from a certain direction, the flow direction of the liquid sprayed from the conveying pipe 401 is similar to the flow direction of the gas, so that the flow directions of the gas and the liquid can be more coordinated, and in this way, the liquid can be better distributed in the barrel 101 along the direction of the gas flow.

[0042] In one embodiment, for the above-mentioned air exhaust assembly 5, the air exhaust assembly 5 comprises an air exhaust box 501 fixedly connected to the top of the barrel 101, a box cover 502 fixedly installed on the top of the air exhaust box 501, a plurality of filter cartridges 503 fixedly connected to the bottom of the box cover 502, and an air exhaust groove 504 formed in the top of the box cover 502.

[0044] In one embodiment, for the above-mentioned mounting box 201, the bottom of the mounting box 201 is fixedly connected with a support leg 6.

[0045] The support leg 6 can provide powerful support to the entire device by means of the mounting box 201. Under the stable support of the support leg 6, the stability of the device during operation can be effectively guaranteed.

[0046] Through the technical scheme, 1, the inclined blowing assembly 2 continuously inclines and blows the raw materials in the fluidization assembly 1, so that the raw materials continuously move to the discharge assembly 3 while being fluidized. At the same time, the liquid spraying assembly 4 can spray the granulation liquid to the outer surface of the continuously moving raw materials, so that the raw materials form granular products. The above arrangement enables the raw materials to continuously move in the fluidization assembly 1, avoiding the situation that the granulation liquid wraps too much on the surface of the raw materials due to the long stay of the raw materials in the fluidization assembly 1, so that the overall size of the produced products can be kept consistent; 2, the motor 305 and the rotating shaft 303 can drive the plurality of discharge plates 304 to rotate upwards, at this time, the continuously rotating discharge plates 304 can drive the products blown by the inclined airflow to rotate together, so that the products can be discharged from the inside of the barrel 101. The above arrangement can effectively avoid the problem that the products directly contact and accumulate on the inner wall of the barrel 101 under the blowing of the inclined airflow, ensuring the smoothness and continuity of the product discharge process, so that the products can be stably and normally discharged from the inside of the barrel 101, greatly improving the production efficiency and reducing many production risks and additional maintenance costs caused by poor discharging.
