[0002] Although the existing phenolic resin powder temporary storage equipment has been continuously innovated and developed, basically meeting people's needs, there is still room for improvement.

[0003] For example, the patent document with the publication number CN214645033U discloses a phenolic resin moisture-proof and anti-blocking device, including a crushing bin. The top of the crushing bin is provided with a drying chamber through a support rod. One side of the drying chamber is connected with a feed inlet in a penetrating manner, and a cavity is opened inside the drying chamber. The bottom of the cavity is connected with a feeding pipe in a penetrating manner, and the cavity is connected with the crushing bin in a penetrating manner through a feeding port and the feeding pipe. An air outlet is opened on one side of the cavity, and a heating sheet is correspondingly arranged on the other side of the air outlet. An air inlet hole is opened on the heating sheet, and a fixed shell is correspondingly arranged on the other side of the heating sheet opposite to the drying chamber. The fan blades rotated on one side driven by the motor fixed inside the connecting plate cooperate with the heating heating sheet to blow the moisture on the phenolic resin placed in the cavity, so that the moisture is discharged through the air outlet arranged on one side of the drying chamber, thereby achieving the effect of reducing the caking, agglomeration and blocking of the discharge port of the raw material due to moisture.

[0004] For the above resin temporary storage equipment, although hot air is used to assist in drying the resin and the agglomerated raw materials are dispersed by the auger shaft, the fine particles and powders of the resin are likely to overflow and generate dust from the filter screen, and at the same time, the interface between the storage bin and the auger bin is still prone to blockage. Therefore, a phenolic resin powder fluidized anti-blocking bin is urgently needed to solve the above problems. Content of the Utility Model

[0033] The following will clearly and completely describe the technical solutions in the present utility model in conjunction with the drawings in the present utility model.

[0034] Embodiment 1:

[0035] Referring to the accompanying drawings in the specification Figures 1-4, the utility model provides a phenolic resin powder fluidized anti-blocking silo, wherein the temporary storage mechanism 100 is mainly composed of a storage bin 110 for resin storage. The storage bin 110 serves as a temporary storage space for phenolic resin powder, providing raw material reserves for subsequent discharging operations;

[0036] The discharging mechanism 200 takes the auger bin 210 connected to the discharging port of the storage bin 110 as the core. An auger shaft 211 is arranged inside the auger bin 210, which is responsible for outputting the phenolic resin raw materials in the storage bin 110. The rotation of the auger shaft 211 pushes the internal resin raw materials towards the discharging port of the auger bin 210, realizing the function of continuous discharging;

[0037] A hole frame 213 is connected to the feeding port of the auger bin 210, and a dredging rod 214 is inserted into the hole frame 213. The dredging rod 214 is located at the midpoint of the interface between the storage bin 110 and the auger bin 210. An eccentric ring 212 is arranged on the auger shaft 211 below the dredging rod 214. As the auger shaft 211 rotates, the eccentric ring 212 rotates together. Due to its eccentric design, it will intermittently lift the dredging rod 214, causing the dredging rod 214 to move up and down in the hole frame 213, thereby assisting in dredging the interface between the storage bin 110 and the auger bin 210 and preventing materials from accumulating and blocking at this place. The eccentric ring 212 and the auger shaft 211 are connected by a cross-shaped or rice-shaped bracket, which not only ensures the synchronous rotation of the eccentric ring 212 and the auger shaft 211 but also enhances the structural stability. The bottom end of the dredging rod 214 is spherical, and a ring-shaped groove for the bottom end of the dredging rod 214 to sink into is opened on the eccentric ring 212, making the lifting of the dredging rod 214 by the eccentric ring 212 smoother and ensuring the stability of the dredging rod 214 during the up and down movement. Auxiliary rods are symmetrically distributed on the surface of the dredging rod 214, enhancing the dredging effect of the dredging rod 214. At the same time, the overall width of the dredging rod 214 is smaller than the aperture of the discharging port of the storage bin 110, ensuring that it can effectively dredge the interface without affecting the normal falling of materials;

[0038] A cutter bar 215 is connected to the spiral blade of the auger shaft 211, and the cutting edge direction of the cutter bar 215 faces the rotation direction of the auger shaft 211. During the process of the auger shaft 211 rotating to push materials, the cutter bar 215 can break up the agglomerated resin, ensuring that the materials can smoothly pass through the auger bin 210 and further avoiding the occurrence of blockage.

[0039] Temporary storage stage: Raw materials are added to the storage bin 110 through a pipeline connected to the feeding port of the storage bin 110 for storage, preparing for subsequent discharging operations;

[0040] Discharging stage: When discharging is required, the auger shaft 211 starts to rotate. On the one hand, the auger shaft 211 continuously pushes the internal resin raw material towards the discharge port of the auger bin 210. On the other hand, the cutter bar 215 rotates along with the spiral blade of the auger shaft 211 to break up the agglomerated resin and ensure the smooth conveying of the material. As the resin at the starting position of the auger shaft 211 decreases, the resin in the storage bin 110 continues to fall into the auger bin 210 under the action of gravity to complete continuous discharging. Meanwhile, during the discharging process, the rotation of the auger shaft 211 drives the eccentric ring 212 to rotate, and the eccentric ring 212 intermittently jacks up the dredging rod 214, causing the dredging rod 214 to rise and fall, and assisting in dredging the interface between the storage bin 110 and the auger bin 210 to prevent the material from clogging at this part and ensuring the stable operation of the phenolic resin powder fluidized anti-blocking bin.

[0041] Embodiment 2:

[0042] Referring to the accompanying drawings of the specification Figure 3 , the difference between this embodiment and the above embodiment is that the storage bin 110 and the auger bin 210 adopt a split structure and are fixed by flange bolts, which not only ensures the tightness and stability of the connection between the two bins, ensuring that there is no leakage or loosening during the material storage and transportation process, but also when maintenance work is carried out, the operator only needs to remove the flange bolts between the storage bin 110 and the auger bin 210 to easily separate the two, enabling the maintenance personnel to comprehensively inspect, clean and repair the components inside the storage bin 110 and the auger bin 210 respectively;

[0043] The inside of the storage bin 110 is connected with electric heating tubes 111, and its control panel extends to the surface of the storage bin 110 for convenient operation by the operator. The electric heating tubes 111 are located below the feeding port of the storage bin 110 and are distributed in a spiral shape so that the electric heating tubes 111 can heat the phenolic resin raw material in the storage bin 110 more evenly.
