Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for recycling and recycling a used fish net, in particular to a method in which the recovered waste fish net is soaked in water to precipitate and separate foreign matter such as dust and sand. The segment type is heated and melted, and the heating temperature of the different sections (from low to high to low) is used to discharge the water vapor, and then the plastic pellets are obtained by a process such as extrusion and pelletizing. [Prior Art] At this stage, the recycling process of used fish nets [please refer to the first picture]: (a) cut the used fish nets into appropriate lengths by using a chopper, and (b) cut them by conveyor belts. The broken waste fish net is sent to the crusher for crushing; (c) the conveyor belt is transported to the screening machine to remove the mud sand and the stone particles; (d) the waste fish net is sorted and placed in the washing tank for cleaning; Putting the used fish net into a dewatering tank for dehydration; (1) placing the used fish net into the mixing tank; (g) discharging the used fish net into the heating device through the feeding device and then discharging the turbulent material after heating; (h) The flow is sent to an extruder to be extruded into a noodle-like shape and then cooled to (i) the noodle-like shape is drawn to a cutting device, and the extruded plastic is cut into pellets. The above-mentioned S uses the recycling procedure of the used fish net. When the broken waste fish net enters, the moon's first towel is washed and the dewatering tank is dehydrated, the common broken fish net is pulled out of the dewatering tank with the centrifugal force of the rotation of the dewatering tank, resulting in The problem of poor recycling efficiency of used fish nets. (4) f: 'The recycling procedures of the used waste fish nets are complicated, resulting in the high cost of setting up the waste fish nets and not meeting the industrial utilization. 200934633 [Summary of the Invention] This month's people have developed a "recycling method for waste fish nets" in view of the problems faced in the process of recycling used fish nets. They cut the used fish nets into several nets to soak the water to make dust and sediment. After the foreign matter is separated, the several mesh pieces are sent to the crusher to be crushed into crushed net materials, and then the broken net materials are sent to the heating device to be heated and melted and extruded into a flowing material, and then discharged, and then cooled and crushed. The feeding device is again fed into the heating device and is heated and melted to form a flowing material, and then the raw material is sent to an extruder to be extruded into a noodle-like plastic, and then the noodle-shaped plastic is cooled by cooling water. Finally, the cooled noodle-like plastic is pulled to a pelletizer to cut into pellets. The purpose, function, and features of the method for recycling the waste fish net of the present invention will be further described in the following detailed description of the embodiments. [Embodiment] In order to make the present invention further clarify the content of the present invention, the following is a detailed description of the preferred embodiment of the present invention, together with the following description: The method for recycling and recycling the waste fish net of the present invention [Please refer to the second figure] According to a first preferred embodiment of the present invention, the method comprises the following steps: (A) first cutting the recovered waste fish net into a plurality of mesh sheets and then immersing the water to precipitate and separate foreign matter such as dust and sediment, and then feeding the plurality of mesh sheets. The crusher is broken into broken mesh materials; (B) the crushed mesh material is sent to the heating device, so that it passes through different sections of the temperature (the temperature is from low to high and then low), and the melt is melted and extruded into a fluid, and The filter of 60mesh mesh is filtered and discharged. The temperature of the section is 200°C+350°C+220°C. (This step has evaporated the water contained in the broken fishing net and discharged the residual silt filter 200934633. ). However, since the influence of the moisture contained in the process on the product particles is manifested by the evaporation of water, pores are left in the particles. The more water content, the more pores remain in the product particles, which affects the compactness of the particles to some extent. The tensile strength is reduced, and the melt flow rate is also high. In actual operation, the water content should be reduced as much as possible. Therefore, the two-stage melting discharges the water vapor to reduce the water content; therefore, the step (c) is that the above-mentioned fluid is cooled and crushed, sent to the heating device again, and heated to a different section temperature. Dissolved into a stream and filtered through a 60 mesh mesh screen. The temperature of the section is 200t: +350°C + 220°C. (This step further evaporates the water contained in the broken fishing net. Discharge and remove the residual muddy sand), so 'two times of hot melt extrusion to evaporate water to avoid the formation of plastic pores during granulation; step (D) to send the above-mentioned stream into the extrusion At this time, the temperature of the fluid is extruded between TC-21 (TC) and filtered through a mesh of 80 mesh mesh, and then extruded into a noodle-like plastic; in step (E), the above-mentioned noodle-shaped plastic is cooled by cooling water ( The cooling water temperature range of this embodiment is about -35-45 C)'. Next step (F) is to send the cooled noodle-like plastic to a pelletizer to cut into pellets of plastic pellets. Please also refer to the third figure, which is A second embodiment of the present invention, which differs from the first embodiment described above In this embodiment, it is considered that when the amount of waste fish nets is not much recycled, plastic recyclable materials (here, waste thermoplastic i·reservoir reclaimed materials are taken as an example) may be mixed, wherein the surface of the plastic recyclable materials is included. Those who are covered with a printed plastic film (such as pvc material) or made of plastics of different materials can be washed with water by crushing the coarse-rolled crushed material. Separation (for example, ρπ材7 200934633 will sink and the 'PE material will float up'), and then dehydrated and dried. Here, the waste fish net recovered in this embodiment is exemplified by PE material, and the plastic recovery recyclate is relatively When the thermoplastic PE material is required to participate in the recycling, it is the case that the step (A) is used to cut the waste fish net into several pieces of mesh and then soak the water to separate the foreign matter such as dust and sediment. Then, the plurality of mesh sheets are sent to the crusher to be crushed into crushed net materials; and step (B') is sent to the heating device to make it pass through different sections of the temperature (the temperature is from low to high and then low). Hot melt pressure In the form of a fluid, the temperature of the section is 2〇〇+350 •>220°C, and is filtered through a filter of 60mesh mesh, and this step also evaporates the water contained in the broken fishing net. Discharge and remove the residual muddy sand. However, if the process still contains water, the effect of the moisture on the product particles will be reflected in the pores remaining in the particles after evaporation. The more water content, the product particles remain. The more pores, the degree of density of the particles to a certain extent 'reduces the tensile strength, the melt flow rate is also relatively high, the water content should be reduced as much as possible in the actual operation. Therefore, the two-stage melting will steam the water. The crucible is discharged to reduce the water content; therefore, the step (C) is to cool the above-mentioned stream and then mix it with the plastic reclaimed pieces and then feed it into the heating device to pass the temperature of the different sections (low to high and then low). The product is heated and melted and extruded into a stream, and is filtered through a filter of 60 mesh mesh, and the temperature of the section is 200 Χ: +350 Χ:·»22 (Γ(:. If the plastic recyclate in the above step (c,) still has a part of PVC material adhered to the crucible, the heating device of the step (C') can be used for 2 〇 (TC + 35 (TC · > 22 (Γ (: heating and melting into a stream, and filtering through the filter of 60mesh mesh, and then discharging, in order to achieve the effect of removing PVC material, because of the high melting point of pe, the melting point of pvc is low, at 2〇〇°c 200934633 PVC will be sintered into a block shape due to temperature, and then it can be taken into consideration during the transition of the filter screen. At the same time, this step further evaporates the water contained in the broken fishing net and filters out the residual mud sand; then the step (D) ,) the above-mentioned stream is sent to the extruder> At this time, the temperature of the stream is extruded between l90_2i〇°c, and filtered through a filter of 80 mesh mesh, and then extruded into a noodle-like plastic; step (E') After the above-mentioned noodle-shaped plastic is cooled by cooling water (the cooling water temperature range of the embodiment is about 35-45. 〇; then the step (F,) is to send the above-mentioned noodle-shaped plastic into a pelletizer to cut into pellets. Finished product. However, it must be emphasized here that due to the recycling of used fish nets due to its material Different (for example, PE specific gravity: 0.92~0. 94 g/cm3, PP specific gravity 92·92g/cm3 or Nylon specific gravity 1.14 g/cm) 'Recycled thermoplastic recyclables (eg pp, 叩, Nylon) ) must also be separated, using the same plastic recycled material as the recycled waste fish net material's, which are mixed and then involved in the recovery. The second embodiment is exemplified by containing pVC (specific gravity about 1.39~152 g). /cm) and the PE (specific gravity 92·92~0. 94 g/cm3) material of the plastic recyclate is broken into broken pieces, and then the broken matter is put into a solution (such as water) to make different proportions The crushed material exhibits different suspension heights in the solution, which can be separated and taken out. In addition, the heating and melting temperature in the process must be adjusted according to the different materials to be recycled, and the other steps are as described above. It can be clearly seen from the first and second embodiments described above that after the secondary waste net is recovered and heated and melted, the water contained in the waste net that has not been dehydrated and dried only by water washing is completely discharged, thereby Production of recycled plastic particles There is a better compactness 'again, after three times of filter filtration and then discharging', the sand, water and air contained in the melted stream are filtered out, resulting in recycled plastic pellets. Good quality. [Overview of the effect of the characteristics of this creation structure] 1.
