[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0030] Reference Figure 1-6 A continuous dewaxing furnace for fiberglass cloth includes an outer shell 1 with material feeding openings 11 on both sides. A conveying mechanism for moving the fiberglass cloth is located within the outer shell 1. Multiple partitions 2 within the outer shell 1 sequentially divide the inner cavity of the outer shell 1 along the feeding direction into a preheating chamber 21, a dewaxing chamber 22, and a curing chamber 23. The preheating chamber 21 preheats the fiberglass cloth, eliminating moisture on its surface and reducing material melting, thus improving energy efficiency. Gradient heating can also eliminate internal stress generated during roll storage, improving the flatness of the fiberglass cloth.
[0031] The dewaxing chamber 22 controls temperature and airflow to melt and evaporate the wax. The fiberglass cloth is then cured in the curing chamber 23.
[0032] The preheating chamber 21 is equipped with a preheating mechanism, the dewaxing chamber 22 is equipped with a dewaxing mechanism 4, and the curing chamber 23 is equipped with a cooling mechanism. Each of the three chambers has a recovery tank 6 at the bottom. The dewaxed wax is recovered through the recovery tank 6. To facilitate the recovery of wax, pure water can be placed in the recovery tank 6 to facilitate the collection of wax and the subsequent separation and extraction of wax.
[0033] The dewaxing mechanism 4 includes heating plates 41 evenly arranged on the upper part of the dewaxing chamber 22, flow equalization pipes 42 arranged between the heating plates 41, an exhaust port 431 located at the rear of the dewaxing chamber 22, and a circulating fan 43 extending out of the dewaxing chamber 22 and connected to the exhaust port 431. Air outlets 421 are evenly opened on the bottom wall of the flow equalization pipe 42, and an air inlet 422 is connected through the flow equalization pipe 42. The other end of the air inlet 422 is connected to a hot air blower. The heating plates 41 can be silicon carbide infrared heating plates. Heating is achieved through the heating plates 41, and the hot air delivered from the air outlets 421 simultaneously heats the fiberglass cloth evenly, ensuring effective heating and efficient wax removal.
[0034] Based on the above technical solution, when dewaxing the fiberglass cloth, the fiberglass cloth is driven by the conveying mechanism to pass through the preheating chamber 21, the dewaxing chamber 22 and the curing chamber 23 in sequence to preheat, dewax and cure the fiberglass cloth. The heat is evenly distributed on the surface of the fiberglass cloth by the uniformly arranged heating plates 41 and the air outlets 421 designed between the heating plates 41, so as to ensure uniform heating effect and ensure the removal effect of wax.
[0035] In this technical solution, such as Figure 1-6 As shown, the outlet of the circulating fan 43 is connected to an air supply pipe 432, and the other end of the air supply pipe 432 extends into the preheating chamber 21 and is provided with an air outlet. The circulating fan 43, in conjunction with the air supply pipe 432, sends the hot air extracted from the dewaxing chamber 22 into the preheating chamber 21, and uses the residual heat to heat the preheating chamber 21, thereby improving energy utilization.
[0036] In this technical solution, such as Figure 1-6 As shown, multiple air guide plates 433 are rotatably installed at the air outlet. The adjustable design of the air guide plates 433 facilitates the adjustment of the airflow direction to uniformly preheat the fiberglass cloth and ensure a uniform gradient heating effect.
[0037] In this technical solution, such as Figure 1-6 As shown, the preheating mechanism includes multiple heating tubes 3 horizontally arranged on the upper part of the preheating chamber 21. The heating tubes 3 can be resistance heating tubes, arranged along the feeding direction of the fiberglass cloth to ensure uniform heating of the fiberglass cloth.
[0038] In this technical solution, such as Figure 1-6 As shown, the conveying mechanism includes support frames 12 arranged on both sides of the housing 1, an air shaft 13 rotatably mounted on the support frame 12, a plurality of conveying rollers 14 arranged in the housing 1, and a drive assembly 15 for driving the air shaft 13 and the conveying rollers 14 to rotate.
[0039] In this technical solution, such as Figure 1-6As shown, the exhaust port 431 is positioned below the horizontal position of the conveyor roller 14. This facilitates adjustment of the hot air duct, guiding heat through the fiberglass cloth to remove evaporated wax and ensuring thorough dewaxing.
[0040] In this technical solution, such as Figure 1-6 As shown, the cooling mechanism includes a cooling pipe 5 positioned above the conveyor roller 14 and heat-conducting plates 51 fitted around the outside of the cooling pipe 5. Both ends of the cooling pipe 5 extend out of the outer casing 1 and are connected to a circulating water pump. Cooling liquid at a suitable temperature is pumped into the cooling pipe 5 by the circulating water pump to control the cooling temperature of the fiberglass cloth in the curing chamber 23, ensuring a suitable curing temperature and guaranteeing the curing effect of the fiberglass cloth.
[0041] In this technical solution, such as Figure 1-6 As shown, multiple guide plates 61 are arranged at the upper end of the recycling tank 6. The guide plates 61 guide the wax to flow into the recycling tank 6. Since the guide plates 61 are located below the conveyor roller 14, there is still a high temperature at the guide plates 61, which can prevent the wax from solidifying on the guide plates 61 and ensure its good fluidity.
[0042] In this technical solution, such as Figure 1-6 As shown, each of the recycling tanks 6 is provided with a wax discharge port 62 and a waste discharge port 63 on its rear side. The wax discharge port 62 is used to discharge and recycle the mixture of wax and water, while the waste discharge port 63 facilitates the cleaning of the recycling tank 6.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
