[0027] Please see Figure 1-5 This utility model provides a technical solution: a granulation processing spiral feeding device, including a shell 1, a shell cover 2, a connecting bin 3, a magnetic rod 4, a spiral conveying rod 5, a first gear 6, a second gear 7, a motor 8, a receiving plate 9, a controller 10, a pressure sensor 11, a breathable membrane 12, a connecting mesh 13, a solenoid valve 14, a fixing strip 15, and a limiting plate 16. The shell 1 is fitted with a hinged shell cover 2 and a connecting bin 3 fixedly connected to the upper left side of the shell cover 2. A spiral feeding structure is provided inside the shell 1 and the shell cover 2, wherein the spiral feeding structure includes the spiral conveying rod 5. The first gear 6, the second gear 7, the motor 8, and the receiving plate 9 are arranged in a staggered manner on the inner sides of the front and rear ends of the housing 1 and the cover 2. A pressure-sensing exhaust structure is provided on the inner side of the right end of the housing 1.

The detachable connection structure includes a fixing strip 15 and a limiting plate 16. The fixing strip 15 is symmetrically fixed on the lower left side of the cover 2. Specific Implementation Example 1

[0029] To address the problem of existing technologies' difficulty in adsorbing and removing iron substances from the feed material, this embodiment employs the following technical solution: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5First, the raw material to be granulated can be placed in the connecting chamber 3 fixedly connected to the shell cover 2, so that the raw material falls into the shell cover 2 under the action of gravity. It is also convenient for the raw material to be adsorbed and removed by the magnetic rods 4 that are nested and attached at equal intervals on the inner side of the middle of the connecting chamber 3. Then, the controller 10 embedded in the inner side of the upper right rear end of the shell 1 can control the motor 8 nested in the receiving plate 9 to operate. The motor 8 drives the second gear 7 connected to its right side via a coupling to rotate. Since the first gear 6 is meshed on both the front and rear sides of the second gear 7, and the right side of the first gear 6 is fixedly connected to the spiral conveying rod 5 that engages with the shell 1 and the shell cover 2, and the spiral conveying rod 5 is staggered and attached to the shell 1 and the shell cover 2, the operation of the motor 8 makes it easy for the second gear 7 to drive the first gear 6 to rotate, and the first gear 6 to drive the spiral conveying rod 5 to rotate in the shell 1 and the shell cover 2, thereby facilitating the double spiral feeding of the raw material for granulation. Specific Implementation Example 2

[0031] To address the problems in existing technologies, such as difficulty in pressure-sensing exhaust, ineffective reduction of air content in powders, and limited particle density, this embodiment employs the following technical solution: Figure 1 , Figure 2 , Figure 3 and Figure 5 During the conveying process, a breathable membrane 12 and a connecting net 13 are attached and fixed to the inner side of the upper right end of the housing 1. This facilitates the ventilation of the breathable membrane 12 under the protection and limitation of the connecting net 13. The controller 10 can control the pressure sensor 11 embedded in the inner side of the rear right end of the housing 1 and the solenoid valve 14 fixed in the inner side of the lower right end of the housing 1 to work together. After the pressure sensor 11 senses the pressure, the controller 10 controls the solenoid valve 14 to discharge the raw material conveyed by the spiral conveyor in the housing 1 and the cover 2. This facilitates pressure-sensing ventilation, effectively reduces the air content in the powder, and increases the particle density. Specific Implementation Example 3

[0033] To address the problem of inconvenient internal cleaning of the device in existing technologies, this embodiment employs the following technical solution: Figure 2 , Figure 3 and Figure 4 After the device is used up, the limiting plate 16 of the damping connection on the left side of the housing 1 can be rotated outward to disconnect the buckle between the upper end of the limiting plate 16 and the lower left side of the housing cover 2. Then the housing cover 2 can be rotated to disconnect the housing cover 2 and its lower hinge connection to the housing 1, so as to clean the inside of the device. After cleaning, the housing cover 2 and the limiting plate 16 can be rotated in sequence. The limiting plate 16 and the fixing strip 15 are fastened together to limit the housing cover 2 and the housing 1.
