[0031] In the embodiment, as shown in Figure 2 , Figure 3 and Figure 5 , the activated air injection device 51 continuously extracts the air outside, and completes the filtering and heating treatment of the air, then injects the air into the soft tube 521, and the hot air is guided by the soft tube 521 to the bottom end of the storage cylinder 1, and finally the air is discharged from the one-way valve 523, and due to the effect of air flow inertia force, most of the hot air discharged from the one-way valve 523 passes through the gaps of part of the raw materials, flows into the circular tube 31, and flows upward in the circular tube 31, which can exert a pushing force on part of the raw materials, and cooperate with the pressing of the raw materials on the outer circumferential side of the circular tube 31 on the raw materials on the bottom side of the circular tube 31, so that the raw materials below the circular tube 31 can be more easily pushed into the circular tube 31, and the other part of the hot air discharged from the one-way valve 523 passes through the gaps of the raw materials on the outer circumferential side of the circular tube 31, and flows upward in the storage cylinder 1, which can heat the raw materials in the storage cylinder 1, so that the peculiar smell on the raw materials can be quickly dissipated, and the blowing of the hot air on the raw materials can remove the water vapor and small particle impurities on the raw materials together;
[0032] It should be noted that after the heating time of the air injection device 51 reaches, the air injection device 51 injects normal temperature air into the soft tube 521, so as to maintain the effect of removing small particle impurities in the raw materials.

[0034] In the embodiment, as shown in Figure 3 , after the air flows out of the gaps between the raw materials in the storage cylinder 1, the air flows out of the storage cylinder 1 through the air exhaust holes 61, and the air discharged from the storage cylinder 1 can carry out small particle impurities such as peculiar smell, water vapor and dust from the storage cylinder 1, so as to avoid the small particle impurities from re-attaching to the raw materials.
[0035] In further preferable embodiments of the utility model, as shown in Figure 1 and Figure 3As shown, the outer periphery of the top of the storage cylinder 1 is fixedly sleeved with a ring pipe 62, and the inside of the ring pipe 62 communicates with the inside of the exhaust hole 61, and the outer periphery wall of the ring pipe 62 is fixedly provided with an exhaust pipe 63 penetratingly arranged;
[0036] In this embodiment, please refer to Figure 3 As shown, the gas flowing out of the exhaust hole 61 will not be emitted to the space outside the periphery of the device due to the interception of the ring pipe 62, and then the gas is guided by the exhaust pipe 63 to the corresponding maintenance discharge or harmless treatment, so that the space around the device will not be full of odors or sundries such as dust, affecting the health of the operator;
[0037] It should be noted that when installing the device of the present application, the exhaust end of the exhaust pipe 63 is installed outside the factory building, or connected to the gas harmless treatment equipment.
[0038] Working principle: the operator reversely twists the cover 34 to screw out the cover 34 from the wall of the storage cylinder 1, at this time various raw materials can be directly poured into the storage cylinder 1 through the opening at the top end of the storage cylinder 1, and then the cover 34 is screwed into the top opening of the storage cylinder 1 again, so that a closed space is formed in the storage cylinder 1, and the raw material feeding operation is completed;
[0039] After the raw material feeding is completed, the driver 33 drives the spiral blade 32 to continuously rotate, which is because the raw material at the top of the storage cylinder 1 presses and pushes the raw material at the bottom of the storage cylinder 1, so that the outer periphery of the bottom end of the spiral blade 32 is always accumulated around the main shaft of the spiral blade 32, at this time the rotating spiral blade 32 pushes part of the raw material at the bottom of the storage cylinder 1 into the circular pipe 31, pushes the raw material into the circular pipe 31 and moves upward along the circular pipe 31, and finally the raw material at the top opening of the circular pipe 31 emerges and falls to the top side of the supporting ring 41, and the spiral blade 32 can also synchronously drive the push plate 42 located on the top side of the supporting ring 41 to continuously make circular motion around the main shaft of the spiral blade 32 during rotation, the moving push plate 42 pushes the raw material at the corresponding position on the supporting ring 41 to make circular motion, changes the position of the raw material on the supporting ring 41, and makes the raw material slide to the inner wall of the storage cylinder 1 through the centrifugal force of the rotating raw material, finally makes the raw material continuously fall from the top in the storage cylinder 1 to complete the stirring and mixing of the raw material in the storage cylinder 1, at this time small particle impurities attached to the surface of the raw material fall off from the raw material due to the mutual friction of the raw material;
[0040] At the same time when the driver 33 starts, the gas injection device 51 starts at the same time, continuously extracts the external gas, and completes the filtering and heating treatment of the gas, then injects the gas into the soft tube 521, and guides the hot gas to the bottom end of the storage cylinder 1 by the soft tube 521, and finally the gas is discharged at the one-way valve 523. The hot gas discharged at the one-way valve 523 is affected by the gas flow inertia force, most of the gas passes through the gap of part of the raw materials, flows into the circular tube 31, and flows upward in the circular tube 31. A pushing force can be applied to part of the raw materials, so that the raw materials below the circular tube 31 can be more easily pushed into the circular tube 31. At the same time, another part of the hot gas discharged at the one-way valve 523 passes through the gap of the raw materials on the outer periphery of the circular tube 31, flows upward in the storage cylinder 1, and performs a suitable strength heating treatment on the raw materials in the storage cylinder 1. Remove the water vapor on the raw materials, and make the peculiar smell of the raw materials quickly dissipate. At the same time, the hot gas carries small particles, water vapor and peculiar smell gas in the process of passing through, and is discharged from the raw materials and flows into the annular pipe 62 at the exhaust hole 61. Then the gas is guided to the exhaust pipe 63. Discharge to a suitable position.
