Technical Field

[0001] The utility model relates to the technical field of resin feeding, in particular to a phenolic resin feeding device with a protection structure. Background Technique

[0002] Although the existing resin feeding components are constantly innovated and developed, basically meeting people's needs, there is still room for improvement.

[0003] For example, the patent document with the publication number CN214526306U discloses a screw conveyor with a material turning and cooling function. The rotating shaft is fixedly arranged in the middle position inside the conveying box body. The left end of the rotating shaft extends to the outside of the left side of the conveying box body and is fixed through a shaft seat. The right end of the rotating shaft extends to the outside of the right side of the conveying box body and is fixed through a fixed shaft seat. The spiral scraper is fixedly arranged on the rotating shaft. The turning plates are fixedly arranged at each interval position of the spiral scraper. The rubber strips are fixedly arranged at the upper positions of the turning plates. The air blowing ports are evenly and equidistantly fixedly arranged at the upper positions of the cover plate. The air extraction ports are correspondingly arranged at the upper positions of the sides of the conveying box body corresponding to the air blowing ports. It improves the full cooling of phenolic resin fragments, prevents dust pollution, and improves the cooling effect of phenolic resin fragments.

[0004] For the above-mentioned phenolic resin conveying equipment, although the relative air blowing ports and air extraction ports improve the cooling effect of the resin, the screw shaft and the turning plates are prone to block the air flow and change its flow path when rotating, resulting in the resin debris still being easily lifted out from the feeding port or the discharging port along with the air flow. The actual dust prevention effect is still lacking. Therefore, there is an urgent need for a phenolic resin feeding device with a protection structure to solve the above problems. Content of the Utility Model

[0005] In order to overcome the above technical problems, the purpose of the utility model is to provide a phenolic resin feeding device with a protection structure to solve the problem that for the above-mentioned phenolic resin conveying equipment, although the relative air blowing ports and air extraction ports improve the cooling effect of the resin, the screw shaft and the turning plates are prone to block the air flow and change its flow path when rotating, resulting in the resin debris still being easily lifted out from the feeding port or the discharging port along with the air flow, and the actual dust prevention effect is still lacking as mentioned in the above background technique.

[0006] The utility model provides the following technical solution: A phenolic resin feeding device with a protection structure, including a conveying mechanism, and the conveying mechanism includes a conveying bin and a screw shaft with turning plates inside.

[0007] It also includes a cooling mechanism. The cooling mechanism includes a cooling box with liquid inside and its surface attached to the conveying bin. The top end of the cooling box is connected to an exhaust duct connected to an external blower, and several return ducts that communicate the inside of the cooling box and the conveying bin are connected to the cooling box on the outside of the exhaust duct.

[0008] To implement the above technical solution, with liquid stored in the cooling box, in combination with the exhaust duct and the return ducts, the hot air flow in the conveying bin can be sucked into the cooling box, so as to use the liquid for temperature reduction and dust removal. Compared with the prior art, when the device sucks air, the inlet and outlet of the conveying bin will become air inlets, avoiding accidental dust emission at these two places.

[0011] As a further improvement of the present utility model, the bottom end of the bin body of the conveying bin is inclined towards the cooling box, and the inclination angle is less than ten degrees.

[0012] To implement the above technical solution, it makes the resin particles move closer to the cooling box during movement, improving the heat conduction effect.

[0013] As a further improvement of the present utility model, two water pipes are connected to the outside of the cooling box, and the two water pipes are respectively connected to a clean water pipe and a sewage pipe.

[0015] As a further improvement of the present utility model, a water level sensor is installed inside the cooling box, and the distance between the highest liquid level and the bottom end of the exhaust duct is not less than ten centimeters.

[0016] To implement the above technical solution, the water supply speed of the water pipe is controlled by the water level sensor to avoid the liquid level inside the cooling box being too high.

[0017] As a further improvement of the present utility model, the bottom end of the cooling box is inclined towards the sewage drain pipe.

[0018] To implement the above technical solution, it makes the resin debris easier to approach the sewage drain pipe.

[0019] As a further improvement of the present utility model, the air inlet of the return duct is at the top end inside the conveying bin, and a filter screen that blocks the resin particles is connected at the air inlet of the return duct.

[0020] Implementing the above technical solution can prevent resin particles with a larger diameter from entering the return air duct.

[0021] As a further improvement of the present utility model, the air outlet of the return air duct is below the liquid level of the cooling tank.

[0035] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention.

[0036] Embodiment 1:

[0037] Referring to the accompanying drawings in the specification Figures 1-4 , the present invention provides a phenolic resin feeding device with a protection structure, wherein the conveying mechanism 100 is composed of a conveying bin 110 and an auger shaft 111 with a turning plate inside. The conveying bin 110 serves as a channel for material conveying, providing space for the transmission of phenolic resin particles. The auger shaft 111 rotates inside the conveying bin 110, and the turning plate on it pushes the phenolic resin particles to move along the conveying bin 110, conveying from the feeding port to the discharging port;

[0038] The cooling box is connected to the pipeline: The cooling mechanism 200 is mainly the cooling box 210, which contains a water liquid inside, and its surface is attached to the conveying bin 110, capable of exchanging heat with the conveying bin 110. The top of the cooling box 210 is connected to an exhaust duct 211 connected to an external fan. Through the suction of the external fan, the air pressure above the water liquid in the cooling box 210 is reduced. A number of return air ducts 212 are connected to the outside of the cooling box 210, and these return air ducts 212 connect the inside of the cooling box 210 and the conveying bin 110, enabling the hot air flow in the conveying bin 110 to enter the cooling box 210;

[0039] Water level control and water pipe connection: Two water pipes 214 are connected to the outside of the cooling box 210, respectively connected to the clean water pipe and the sewage pipe. Water is supplied to the cooling box 210 through the clean water pipe, and the used water is discharged through the sewage pipe, forming a flowing water liquid in the cooling box 210 to ensure the continuity of the cooling effect. A water level sensor is installed inside the cooling box 210 to ensure that the distance between the highest liquid level and the bottom end of the exhaust duct 211 is not less than ten centimeters, preventing the water liquid from being sucked into the exhaust duct 211. The bottom end of the cooling box 210 is inclined towards the sewage drain pipe 214, which is beneficial to the discharge of sewage and avoids the accumulation of sewage in the cooling box 210;

[0040] Return air duct and extension piece design: The air inlet of the return air duct 212 is located at the inner top of the conveying bin 110. A filter screen is connected at the air inlet to block resin particles from entering the return air duct 212, ensuring the smooth entry of hot air into the cooling tank 210 while preventing material loss and pipeline blockage. The air outlet of the return air duct 212 is below the liquid level of the cooling tank 210, allowing the hot air flow to fully contact the water liquid, enhancing the cooling effect. An extension piece 213 is connected to the outside of the cooling tank 210 and is in contact with the bottom end of the conveying bin 110. Both the cooling tank 210 and the extension piece 213 are made of copper. Copper has good thermal conductivity and can more effectively transfer the heat of the resin particles from the conveying bin 110 to the water liquid in the cooling tank 210.

[0041] Feeding process: When feeding, phenolic resin particles enter from the feeding port of the conveying bin 110. As the auger shaft 111 rotates, the particles are gradually pushed by the turning plate and move to the discharge port, completing the material conveyance.

[0042] Cooling process: In the cooling stage, the exhaust duct 211 is externally connected to a high-power fan for air suction, reducing the air pressure above the water liquid in the cooling tank 210. At this time, the hot air flow in the conveying bin 110 is sucked into the water in the cooling tank 210 through the return air duct 212 under the action of the air pressure difference. The water liquid adheres to the heat and possible resin debris carried in the hot air flow, achieving the cooling and purification of the hot air flow. At the same time, the heat of the resin particles is transferred from the conveying bin 110 to the cooling tank 210 and the extension piece 213 in close contact with it, and then transferred to the water liquid in the cooling tank 210 by them. In this process, the two water pipes 214 supply water and discharge water respectively, making the water liquid in the cooling tank 210 flow continuously, continuously taking away heat, and ensuring the stability and high efficiency of the cooling effect.

[0043] Example Two:

[0044] Referring to the attached drawings of the specification Figure 3 , the difference between this example and the above example is that the conveying bin 110 adopts a structural form composed of a bin body and a bin cover, and is fixed by bolts. This design not only ensures the stability of the overall structure of the conveying bin 110, ensuring that there will be no loosening or leakage during the conveying of phenolic resin particles, but also provides convenience for the maintenance of the equipment. The bolt connection method enables the bin body and the bin cover to be easily separated when needed, facilitating the inspection, cleaning, and maintenance of internal components. The feeding port of the conveying bin 110 is set at the top of the bin cover;

[0045] The bottom end of the bin body of the conveying bin 110 is inclined towards the cooling tank 210, and the inclination angle is less than ten degrees, which helps to better transfer heat to the cooling tank 210 during the cooling process.
