Detailed Description
Embodiment 1, refer to fig. 1-2, a crushing and drying device for waste fishing net recovery comprises a barrel 1 and a plurality of layers of crushing cutters 2 arranged in the barrel 1, wherein an electric heating device 3 is arranged on the inner side wall of the barrel 1, an exhaust device 4 is arranged on the top of the barrel 1, the plurality of layers of crushing cutters 2 are rotatably connected with the bottom of the barrel 1, and a rotary driving mechanism 5 is arranged at the bottom of the barrel 1 and is in driving connection with the plurality of layers of crushing cutters 2.
In this embodiment, set up multilayer crushing sword 2 in barrel 1 and can smash the fishing net fast, the fishing net is got rid of on the barrel 1 lateral wall by electric heater unit 3 heating stoving after being smashed, and the fishing net can be by rebound to multilayer crushing sword 2 department again by cutting smashing after striking on the barrel 1 lateral wall to this circulation is repeated to realize smashing fast and stoving the fishing net. The fishing net at different height positions in the barrel 1 can be crushed by the multilayer crushing knife 2, and the speed is high in the process of being cut and thrown out to collide with the side wall of the barrel 1, so that a certain amount of heat is generated by collision, and the fishing net can be heated and dried in an auxiliary manner. The exhaust device 4 arranged at the top of the barrel 1 can exhaust the water vapor in the barrel 1 which is heated and evaporated by the water in the fishing net, so that the drying speed of the fishing net is accelerated. Specifically, the exhaust device 4 includes a cover 41, an exhaust port 42 is disposed on the cover 41, a baffle filter mechanism 43 is disposed below the cover 41, and an exhaust mechanism 44 is disposed at the exhaust port 42. The cover 41 is provided with a plurality of air inlets 45. The baffle filter mechanism 43 arranged below the cover 41 at the air outlet 42 can prevent the fishing net from flying out of the air outlet 42.
Specifically, the multi-layer crushing cutter 2 comprises a plurality of groups of annular crushing cutters 21 from top to bottom, the diameters of the annular crushing cutters 21 are sequentially increased from top to bottom, the plurality of groups of annular crushing cutters 21 are fixedly connected through a rotating shaft 22, wherein the annular crushing cutters 21 comprise rotating shaft connecting holes 211 and annular supports 212, and the rotating connecting holes 211 are in supporting connection with the annular supports 212 through a plurality of cutting cutters 213. The multilayer crushing sword 2 comprises the annular crushing sword 21 that multiunit diameter is different, and the annular crushing sword 21 is connected between pivot connecting hole 211 and ring support 212 cuts 213 can realize the effective cutting crushing to the fishing net, because crushing drying device of this embodiment is industrial processing equipment, its size is great, utilizes pivot connecting hole 211 and ring support 212 cooperation to connect the setting to cutting knife 213, can improve the stability of cutting knife 213 in the rotation crushing in-process, avoids cutting knife 213 to cause the fracture damage because of quick rotation cutting.
