Description

Technical Field

[0001] This invention belongs to the field of waste fishing net wire recycling and processing technology, specifically, it relates to a waste fishing net wire recycling device. Background Technology

[0002] The recycling and processing of waste fishing net wire is an important industrial sector at the intersection of resource recycling and environmental governance. Its core is to transform waste fishing net wire into reusable industrial raw materials through physical and chemical technologies, achieving the dual goals of "waste reduction" and "regeneration of resource value," while simultaneously alleviating environmental pollution problems caused by discarded fishing net wire in the ocean and on land. Currently, the recycling and processing process in this field mainly includes five stages: "collection, dismantling, crushing, sorting, and deep processing," with the crushing stage being the key link between "primary processing" and "deep processing."

[0003] However, traditional equipment mostly performs single-stage crushing. Due to the high toughness of fishing net wire, the degree of crushing is limited, resulting in large particle size and poor uniformity of the crushed material, which cannot meet the requirements for subsequent granulation and directly affects the quality of recycled products. Although some equipment attempts to achieve secondary crushing through a transfer structure, it requires re-feeding through the hopper, which is complicated and reduces recycling efficiency. It may also cause material accumulation inside the hopper. Furthermore, the crushed fishing net wire is light and easily adsorbed, and the material easily adheres to the inner wall, which not only blocks the feeding channel and affects continuous operation, but also causes mold and contamination of raw materials if left for a long time. Frequent manual disassembly and cleaning are required, which increases operating costs and reduces recycling rate due to material loss, thus driving up costs and hindering the large-scale development of the industry.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0006] A waste fishing net wire recycling device includes a support frame and a crushing shell disposed on the side wall of the support frame.

[0007] The crushing shell is equipped with a pair of crushing rollers rotating in opposite directions. The top and bottom of the crushing shell are rotatably connected to guide storage hoppers. The guide storage hopper at the top is used to guide the material to fall into the crushing rollers, and the guide storage hopper at the bottom is used to collect the crushed material. The rotation of the pair of guide storage hoppers is used to rotate the guide storage hopper that collects the crushed material to the top, so that the material falls back onto the crushing rollers to complete the secondary crushing.

[0008] A positioning plate is installed on the side wall of the crushing shell. A pair of protrusions corresponding to the guide storage hopper are installed on the side wall of the positioning plate. The protrusions are in contact with the top rod inserted into the side wall of the guide storage hopper. A sealing plate is rotatably installed inside the guide storage hopper, and a rocker arm is installed on the sealing plate. When the guide storage hopper rotates, the protrusions separate from the top rod, and the push rod pulls the rocker arm to deflect. In turn, the rocker arm drives the sealing plate to seal the guide storage hopper and prevent the crushed material from falling prematurely.

[0009] An airbag is installed at both ends of the pair of guide storage hoppers. A connecting pipe is installed on the airbag and connected to the other guide storage hopper. After the airbag and the guide storage hopper rotate synchronously, the airbag is squeezed against the support, which drives the gas to be sprayed onto the guide storage hopper located at the top, so that the material adsorbed on the inner wall can fall freely.

[0010] In a preferred embodiment of the present invention, the support consists of a pair of upright plates and a base plate connected to each other, and the pair of upright plates are connected to the side wall of the crushing shell. The pair of upright plates are symmetrically mounted on the base plate. A reinforcing rib is installed at the connection between the upright plate and the base plate, and the reinforcing rib is triangular. Positioning holes are installed around the base plate, and the positioning holes are used for later connection with external components.

[0011] In a preferred embodiment of the present invention, a crushing chamber is provided inside the crushing shell, the crushing roller is rotatably disposed in the crushing chamber, a feed inlet is provided at the top of the crushing chamber, and a discharge outlet is provided at the bottom of the crushing chamber. Both the feed inlet and the discharge outlet are conical. The feed inlet is connected to a guide storage hopper located at the top, and the discharge outlet is connected to a guide storage hopper located at the bottom.

[0012] In a preferred embodiment of the present invention, a synchronous shaft is installed at the center of the pair of crushing rollers. The synchronous shaft is movably connected to the crushing shell and the support. A synchronous motor is installed on the outer wall of the support. The output end of the synchronous motor is connected to one of the synchronous shafts. Gears are installed at the other ends of the pair of synchronous shafts, and the gears mesh with each other. A protective cover is installed on the side wall of the support, covering the outside of the gears. A bending frame is installed on the side wall of the support, and the bending frame is connected to the synchronous motor. An inclined plate is installed on the bending frame.

[0013] In a preferred embodiment of the present invention, the guide hopper is provided with a conical surface, which facilitates material discharge, and the connecting pipe is connected to the conical surface. A sealing door is installed on the end face of the guide hopper by bolts, and a positioning frame is installed on the side wall of the bracket. A drive motor is installed on the positioning frame, and a pressure arm is installed on the drive motor. The end of the pressure arm is connected to the guide hopper.

[0014] In a preferred embodiment of the present invention, a synchronization frame is installed between a pair of guide hoppers. The synchronization frame is located on the side wall of the crushing shell. A sliding plate is installed at the bottom of each guide hopper. The sliding plate is attached to the side wall of the crushing shell. A slide rail is installed on the crushing shell. The slide rail is arc-shaped and is slidably connected to the sliding plate.

[0015] In a preferred embodiment of the present invention, a pair of protrusions are located at the top and bottom of the positioning disk, and a sleeve is installed at the end of the push rod. A ball is installed inside the sleeve, and the end of the ball is in contact with the surface of the protrusion.

[0016] In a preferred embodiment of the present invention, an arched bracket is installed on the inner wall of the guide storage hopper, the top rod passes through the arched bracket, a pressure plate is installed on the top rod, and a compression spring is sleeved on the top rod. One end of the compression spring is engaged with the pressure plate, and the other end of the compression spring is installed on the arched bracket. The compression spring is used to compress the top rod and the positioning plate to fit together.

[0017] In a preferred embodiment of the present invention, a push rod is installed at the end of the push rod, and protrusions are installed at both ends of the push rod. A strip groove is provided on the rocker arm, and the protrusions are slidably disposed in the strip groove.

[0018] In a preferred embodiment of the present invention, a positioning shaft is installed at the rotation center of the sealing plate, the positioning shaft is connected to the rotation center of the rocker arm, and both ends of the positioning shaft are rotatably connected to the side wall of the guide storage hopper.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] This invention features a pair of rotatable guide hoppers that transfer the initially crushed material to the top and re-enter the crushing chamber for secondary crushing by the crushing rollers. Compared to single-stage crushing, this significantly reduces the particle size of the fishing net wire material, making it more suitable for subsequent granulation, recycled fiber production, and other recycling processes, thus laying the foundation for improving the quality of recycled products. Simultaneously, the sealing control mechanism of the guide hoppers prevents premature material fall during rotation, ensuring the crushing process proceeds in an orderly rhythm of "initial crushing - transfer - secondary crushing." Furthermore, the airbag and connecting pipe assembly... The air-blowing structure can spray and remove materials adsorbed on the inner wall by airflow when the guide storage hopper rotates. The airflow can break the adhesion between the material and the inner wall and form disturbance, avoiding problems such as poor material discharge or mold growth caused by material residue. This design not only reduces the frequency of manual disassembly and cleaning of the guide storage hopper, reducing maintenance workload and time costs, but also works in conjunction with the closed-loop process of secondary crushing and the precise control of materials by the sealing plate to ensure that all the waste fishing net wire material put in can enter the crushing chamber and be crushed, without material waste caused by residue or leakage.

[0021] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0036] Example 1:

[0037] like Figures 1 to 8 As shown, a waste fishing net wire recycling device includes a support 11 and a crushing shell 1 disposed on the side wall of the support 11.

[0038] Inside the crushing shell 1, a pair of crushing rollers 13 rotating in opposite directions are installed. Guide hoppers 14 are rotatably connected to the top and bottom of the crushing shell 1. The top guide hopper 14 guides material into the crushing rollers 13, while the bottom guide hopper 14 collects the crushed material. Rotating the pair of guide hoppers 14 rotates the guide hopper 14 collecting the crushed material to the top, causing the material to fall back onto the crushing rollers 13, completing secondary crushing. This secondary crushing achieved through the rotation of the guide hoppers 14 significantly reduces the particle size of the material, meeting the needs of subsequent processing and improving the quality of the recycled product.

[0039] A positioning disc 2 is installed on the side wall of the crushing shell 1. A pair of protrusions 21 corresponding to the guide storage hopper 14 are installed on the side wall of the positioning disc 2. The protrusions 21 are in contact with the top rod 22 inserted into the side wall of the guide storage hopper 14. A sealing plate 23 is rotatably installed inside the guide storage hopper 14, and a rocker arm 232 is installed on the sealing plate 23. When the guide storage hopper 14 rotates, the protrusions 21 and the top rod 22 separate, and the push rod 24 pulls the rocker arm 232 to deflect. Then, the rocker arm 232 drives the sealing plate 23 to seal the guide storage hopper 14, preventing the crushed material from falling prematurely. The sealing is achieved through the linkage of the protrusions 21, the top rod 22 and the sealing plate 23, which prevents the material from falling prematurely during transfer and ensures the orderly process.

[0040] A pair of guide hoppers 14 are equipped with airbags 3 at both ends. Connecting pipes 31 are installed on the airbags 3 and connected to the other guide hopper 14. When the airbags 3 and guide hoppers 14 rotate synchronously, the airbags 3 and support 11 compress, causing gas to be sprayed onto the top guide hopper 14, allowing material adsorbed on the inner wall to fall freely. This structure uses the airbags 3 to generate gas and remove material residue from the inner wall, preventing obstructed discharge and improving material utilization.

[0041] like Figures 1 to 8As shown, in a specific embodiment, the support 11 consists of a pair of upright plates 111 and a base plate 112 connected to each other. The pair of upright plates 111 are connected to the side wall of the crushing shell 1. The pair of upright plates 111 are symmetrically mounted on the base plate 112. A reinforcing rib 113 is installed at the connection between the upright plate 111 and the base plate 112, and the reinforcing rib 113 is triangular. Positioning holes 114 are installed around the base plate 112. The positioning holes 114 are used for later connection with external components. This structure enhances the stability of the support through the reinforcing rib 113, and the positioning holes 114 facilitate the fixing of the equipment, thereby improving the overall reliability of the equipment.

[0042] like Figures 1 to 8 As shown, furthermore, a crushing chamber 12 is provided inside the crushing shell 1, and a crushing roller 13 is rotatably disposed in the crushing chamber 12. A feed inlet 121 is provided at the top of the crushing chamber 12, and a discharge outlet 122 is provided at the bottom of the crushing chamber 12. Both the feed inlet 121 and the discharge outlet 122 are conical. The feed inlet 121 is connected to a guide hopper 14 located at the top, and the discharge outlet 122 is connected to a guide hopper 14 located at the bottom. The conical feed inlet 121 and discharge outlet 122 can guide materials to enter and exit quickly, avoiding material accumulation and ensuring crushing and collection efficiency.

[0043] like Figures 1 to 8 As shown, a synchronous shaft 131 is installed at the center of a pair of crushing rollers 13. The synchronous shaft 131 is movably connected to the crushing housing 1 and the support 11. A synchronous motor 132 is installed on the outer wall of the support 11. The output end of the synchronous motor 132 is connected to one of the synchronous shafts 131. Gears 135 are installed at the other end of each pair of synchronous shafts 131, and the gears 135 mesh with each other. A protective cover 136 is installed on the side wall of the support 11, covering the outside of the gears 135. A bending frame 133 is installed on the side wall of the support 11, and the bending frame 133 is connected to the synchronous motor 132. An inclined plate 134 is installed on the bending frame 133. The synchronous shaft 131 and the gears 135 ensure that the crushing rollers 13 rotate synchronously in opposite directions. The protective cover 136 protects the gears, the bending frame 133 fixes the motor, and the inclined plate 134 shields the dust, ensuring stable operation of the equipment.

[0044] like Figures 1 to 8 As shown, the guide hopper 14 is further provided with a conical surface 141, which facilitates material discharge. The connecting pipe 31 is connected to the conical surface 141. A sealing door 142 is bolted to the end face of the guide hopper 14. A positioning frame 145 is installed on the side wall of the bracket 11. A drive motor 144 is installed on the positioning frame 145, and a pressure arm 143 is installed on the drive motor 144. The end of the pressure arm 143 is connected to the guide hopper 14. The conical surface 141 accelerates the material descent, the sealing door 142 facilitates cleaning and maintenance, and the drive motor 144 and the pressure arm 143 drive the hopper to rotate, improving the convenience of operation.

[0045] like Figures 1 to 8 As shown, a synchronization frame 146 is further installed between a pair of guide hoppers 14. The synchronization frame 146 is located on the side wall of the crushing shell 1. A sliding plate 147 is installed at the bottom of each guide hopper 14, and the sliding plate 147 fits against the side wall of the crushing shell 1. A slide rail 148 is installed on the crushing shell 1. The slide rail 148 is arc-shaped and slidably connected to the sliding plate 147. The synchronization frame 146 ensures that the hoppers rotate synchronously, and the sliding plate 147 and the slide rail 148 reduce rotational friction, ensuring stable operation of the hoppers.

[0046] Example 2:

[0047] The difference between the above embodiments and this embodiment is that: Figures 1 to 8 As shown, a pair of protrusions 21 are located at the top and bottom of the positioning disk 2, and a sleeve 212 is installed at the end of the push rod 22. A ball bearing 211 is installed inside the sleeve 212, and the end of the ball bearing 211 is in contact with the surface of the protrusion 21. The ball bearing 211 converts sliding friction into rolling friction, reduces the wear between the push rod and the protrusion, and extends the service life of the component.

[0048] like Figures 1 to 8 As shown, in a specific embodiment, an arched bracket 221 is installed on the inner wall of the guide hopper 14. The top rod 22 passes through the arched bracket 221. A pressure plate 222 is installed on the top rod 22, and a compression spring 223 is sleeved on the top rod 22. One end of the compression spring 223 is engaged with the pressure plate 222, and the other end is installed on the arched bracket 221. The compression spring 223 is used to compress the top rod 22 and the positioning plate 2 to fit together. The compression spring 223 ensures that the top rod 22 always fits against the protrusion 21, ensuring stable triggering of the sealing mechanism and improving sealing reliability.

[0049] like Figures 1 to 8 As shown, further, a push rod 24 is installed at the end of the top rod 22, and protrusions 241 are installed at both ends of the push rod 24. A strip groove 233 is opened on the rocker arm 232, and the protrusions 241 are slidably disposed in the strip groove 233. A positioning shaft 231 is installed at the rotation center of the sealing plate 23, and the positioning shaft 231 is connected to the rotation center of the rocker arm 232. Both ends of the positioning shaft 231 are rotatably connected to the side wall of the guide storage hopper 14. The strip groove 233 converts the linear motion of the protrusions 241 into the rotational motion of the rocker arm 232, and the positioning shaft 231 ensures the stable rotation of the sealing plate 23, ensuring that the sealing action is accurately realized.

[0050] The implementation principle of the waste fishing net wire recycling device of the present invention is as follows:

[0051] The operator first opens the sealed door 142 of the top guide storage hopper 14 to remove the waste fishing net wire. Then, the material is fed into the top guide storage hopper 14. The material slides along the conical surface 141 of the guide storage hopper 14 into the feed inlet 121 and then into the crushing chamber 12. The synchronous motor 132 on the outer wall of the support 11 is started. The output end of the synchronous motor 132 drives one of the synchronous shafts 131 to rotate. Because the gears 135 at the ends of the pair of synchronous shafts 131 mesh with each other, the two synchronous shafts 131 rotate synchronously in opposite directions, which eventually drives the crushing roller 13 to operate and perform the initial crushing of the fishing net wire that has entered the crushing chamber 12. The crushed material falls into the bottom guide storage hopper 14 through the discharge port 122.

[0052] After the bottom guide hopper 14 collects a certain amount of initially crushed material, the drive motor 144 on the side wall positioning frame 145 of the bracket 11 is started. The drive motor 144 drives the pressure arm 143 to rotate, and the end of the pressure arm 143 drives the guide hopper 14 to rotate.

[0053] Before and after the guide hopper 14 rotates, its sealing control mechanism operates synchronously: Before the guide hopper 14 rotates, it is in an initial standby state: the protrusion 21 on the positioning plate 2 is in contact with the push rod 22. At this time, the ball 211 in the sleeve 212 at the end of the push rod 22 rolls in contact with the surface of the protrusion 21. Its core function is to convert the sliding friction between the two into rolling friction, which greatly reduces the frictional resistance before the guide hopper 14 starts rotating. At the same time, the push rod 22 passes through the arched bracket 221. The compression spring 223 between the pressure plate 222 on the push rod 22 and the arched bracket 221 is in a pre-compressed state. The compression spring 223 continuously applies a pushing force to the pressure plate 222 through its own elasticity, thereby driving the push rod 22 to always press the protrusion 21 tightly, ensuring that the two are in a stable contact state, and preparing for the subsequent sealing action to be triggered.

[0054] When the guide hopper 14 receives a rotation command and begins to rotate, the sealing action is triggered: as the guide hopper 14 rotates, the protrusion 21, which was originally in contact with the push rod 22, separates from the push rod 22 due to the change in relative position. At this time, the pre-compression state of the compression spring 223 is released, and the spring force pushes the push rod 22 to move along the through direction of the arched support 221; when the push rod 22 moves, it synchronously drives the push rod 24 connected to its end to move synchronously, and the protrusions 241 at both ends of the push rod 24 slide in the strip groove 233 of the rocker arm 232, whereby... The function of the strip groove 233 is to convert the linear motion of the protrusion 241 into the rotational motion of the rocker arm 232. Therefore, when the protrusion 241 slides, it will cause the rocker arm 232 to deflect around the positioning shaft 231. The rocker arm 232 is linked with the sealing plate 23. When the rocker arm 232 deflects, it directly drives the sealing plate 23 to rotate synchronously, so that the sealing plate 23 completely covers the feeding channel of the guide storage hopper 14, thereby sealing the guide storage hopper 14 and fundamentally preventing the internal crushed material from falling prematurely during the rotation of the guide storage hopper 14, ensuring the orderly progress of secondary crushing.

[0055] When the guide hopper 14 continues to rotate to the preset position (i.e., the original bottom guide hopper 14 reaches the top and the original top guide hopper 14 reaches the bottom), after rotating to the correct position, the push rod 22 on the side wall of the guide hopper 14 will change position with the guide hopper 14 and re-contact with the corresponding protrusion 21 on the positioning plate 2; the protrusion 21 generates a reverse thrust on the push rod 22, pushing the push rod 22 to move in the opposite direction along the through direction of the arched bracket 221. When the push rod 22 moves, it drives the pressure plate 222 to squeeze the compression spring 223, causing the compression spring 223 to re-enter the pressure plate. The material enters the pre-compression state; at the same time, the push rod 22 moves in the opposite direction, synchronously driving the push rod 24 and the protrusions 241 at both ends to slide in the opposite direction. The protrusions 241 slide in the opposite direction in the strip groove 233 of the rocker arm 232, causing the rocker arm 232 to deflect in the opposite direction around the positioning shaft 231. The rocker arm 232 then drives the sealing plate 23 to rotate in the opposite direction, causing the sealing plate 23 to disengage from the feeding channel of the guide storage hopper 14, releasing the seal on the guide storage hopper 14. At this time, the material in the top guide storage hopper 14 can slide normally along the conical surface 141 into the feed inlet 121 and enter the secondary crushing stage.

[0056] During the rotation of the guide hopper 14, the slide plate 147 slides along the slide rail 148 to ensure the stability of the rotation process; after the seal is released, the material in the top guide hopper 14 (original bottom) slides again along the conical surface 141 into the feed inlet 121 and enters the crushing chamber 12 to be crushed twice by the crushing roller 13, so as to achieve fine processing of the material.

[0057] When the airbag 3 rotates synchronously with the guide hopper 14, the airbag 3 at the top is squeezed by the support 11 when it rotates at the bottom, which reduces the internal volume of the airbag 3 and creates a certain pressure in the internal gas, forming a propulsive airflow. This pressurized gas is directionally transported to the guide hopper 14 at the top through the passage formed by the connecting pipes 31, and finally sprayed out from the conical surface 141 connected to the connecting pipes 31. Because the fishing net wire material is light and has a certain degree of adsorption, it easily adheres to the inner wall of the guide hopper 14 after being crushed. The sprayed airflow can directly act on the adsorbed material, breaking the adsorption force between the material and the inner wall through the impact force of the airflow. At the same time, the airflow can also create disturbance on the surface of the conical surface 141, causing the material to detach from the inner wall and slide down the conical surface 141, completely avoiding the problem of poor material discharge caused by material residue, ensuring that all the material can fall smoothly into the crushing chamber 12, and ensuring the continuity of the crushing process and the material utilization rate.
