The filtering is performed in layers so as not to hinder the filtering of the epoxy resin, thereby maintaining the filtering efficiency of the epoxy resin. When the filter unit 200 structure needs to be maintained, the filter unit 200 structure is pulled out from the filter chamber 102 by lifting the round frame 201. The round frame 201 is located above the filter box 1 and is provided with a groove for easy lifting. Then it is lifted to the designated cleaning location and the round frame 201 on the right is pulled, so that the round frame 201 drives the plug plate 205 to separate from the ring 202, and then the filter bottom plate 203 is separated from the ring 202, so as to clean and maintain the filter unit 200 structure in all directions. Through the mutual cooperation between the structures, the solid impurities contained in the epoxy resin mixture can be effectively and continuously filtered with high efficiency, thereby maintaining the production efficiency of the epoxy resin and the efficient use of the device.

[0033] Working principle: When the epoxy resin mixture needs to be filtered through the filtering device, the epoxy resin mixture needs to be poured through the top of the filter box 1 located above the filter unit 200 structure, and then filtered through the conical filter plate 204. The conical filter plate 204 is set to a cone shape so that even if the filtered impurities are piled together, they can be filtered through the higher conical filter plate 204 layers, so as not to hinder the filtration of the epoxy resin, thereby maintaining the filtration efficiency of the epoxy resin. When the filter unit 200 structure needs to be maintained, the filter unit is driven by lifting the round frame 201. The structure 200 is pulled out from the filter chamber 102, and the circular frame 201 is located above the filter box 1 and is provided with a groove for easy lifting. Then it is lifted to the designated cleaning location and the circular frame 201 on the right is pulled, so that the circular frame 201 drives the plug plate 205 to separate from the circular ring 202, and then the filter bottom plate 203 is separated from the circular ring 202, so that the filter unit 200 structure is cleaned and maintained in all directions. Through the mutual cooperation between the structures, the solid impurities contained in the epoxy resin mixture can be effectively and continuously filtered with high efficiency, so as to maintain the production efficiency of the epoxy resin and the efficient use of the device.
