Abstract
Description
Technical fields:
[0001] This utility model belongs to the technical field of metal recycling equipment, specifically referring to a copper granulator. Background technology:
[0002] As a key piece of equipment for processing waste wires and cables, the copper granulator mechanically separates the outer plastic sheath of the wires from the inner copper conductor to obtain high-purity copper granules (commonly known as "copper granules") and plastic particles.
[0003] Most copper granulators on the market currently adopt a modular design: the front end uses a crusher to break the material into mixed particles, and then the mixture is transferred to an independent vibrating screen, air classifier, or water separator for copper-plastic separation. However, this staged processing method has significant drawbacks: First, the series operation of multiple independent devices results in a large production line footprint and high equipment procurement costs, which is difficult for small metal recycling plants with limited funds and space to afford; second, dust pollution and metal loss are easily generated during material transfer between devices; and third, the complex system configuration increases energy consumption and maintenance difficulty. Summary of the Invention:
[0004] The purpose of this utility model is to provide a copper granulator that integrates the crushing component and the vibrating screening component in the same housing, effectively reducing the overall size of the copper granulator and lowering equipment costs, thus meeting the operational needs of small metal recycling plants with limited funds and space.
[0005] A copper granulator includes a housing, a crushing chamber and a screening chamber disposed above and below the housing. The crushing chamber is equipped with a crushing component, and the upper part of the crushing chamber has a crushing inlet communicating with the outside, and the lower part has a crushing outlet communicating with the screening chamber. The screening chamber is equipped with a vibrating screening component with a screening vibration surface located directly below the crushing outlet, and the screening surface of the vibrating screening component is inclined vertically. The screening chamber has a plastic outlet communicating with the outside and the lower inclined end of the screening surface, and a copper particle outlet communicating with the outside and the upper inclined end of the screening surface.
[0006] In the aforementioned copper granulator, the crushing assembly includes a crushing shaft rotatably connected within the crushing chamber and a movable blade disposed on the outer wall of the crushing shaft. A fixed blade that can cooperate with the movable blade is fixed on the inner wall of the crushing chamber. A filter screen is provided in the crushing chamber between the crushing shaft and the crushing feed inlet, and the filter screen has an arc-shaped structure and is arranged around the outer periphery of the crushing shaft and the movable blade.
[0007] In the aforementioned copper granulator, the vibrating screening assembly includes a screening vibrating screen plate that is tilted vertically and mounted on the screening chamber, and a vibrating motor assembly fixed on the machine casing. The screening action surface is the upper surface of the screening vibrating screen plate. The vibrating motor assembly is connected to the screening vibrating screen plate via a crank, and the vibrating motor assembly drives the screening vibrating screen plate to vibrate via the crank.
[0008] In the aforementioned copper wire granulator, an air supply duct and a screening fan are provided on the casing located below the screening vibrating screen plate. The upper port of the air supply duct covers directly below the mesh of the screening vibrating screen plate, and the lower port of the air supply duct is connected to the air outlet of the screening fan. An air supply fan is provided inside the casing, and the air intake end of the air supply fan is connected to the screening chamber through an air intake duct. The corresponding port of the air intake duct is located above the screening vibrating screen plate. The air outlet of the air supply fan is connected to the outside through an exhaust duct, and a filter bag is provided at the outer port of the exhaust duct.
[0009] In the aforementioned copper granulator, a limiting screening plate is provided on the screening chamber located directly above the inclined upper end of the screening vibrating screen. The limiting screening plate has a limiting part and a passing part arranged along the inclined direction of the screening vibrating screen. The passing part and the screening vibrating screen form a conveying channel for the copper particles to be conveyed through by vibration. The limiting part is connected to the side of the passing part away from the copper particle outlet, and the limiting part can prevent the material particles from vibrating and passing over the limiting part.
[0010] In the aforementioned copper granulator, a limiting step surface is provided on the screening cavity located between the plastic discharge port and the inclined lower end of the screening vibrating screen plate. The limiting step surface and the upper surface of the screening vibrating screen plate form a stepped depression that can prevent material particles from continuing to vibrate and be conveyed, thus achieving accumulation.
[0011] In the aforementioned copper granulator, the crushing and feeding port is inclined toward the plastic discharge port.
[0012] This utility model is implemented as follows:
[0013] The outstanding advantages of this utility model compared to the prior art are:
[0014] This utility model has a simple structure, reasonable design and low cost. It integrates the crushing component and the vibrating screening component in the same housing.

[0017] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 :
[0018] A copper granulator includes a housing 1, a crushing chamber and a screening chamber disposed vertically within the housing 1. The crushing chamber is equipped with a crushing component, and the upper part of the crushing chamber has a crushing feed port 2 communicating with the outside, and the lower part has a crushing discharge port 3 communicating with the screening chamber. The screening chamber is equipped with a vibrating screening component with a screening vibration surface located directly below the crushing discharge port 3, and the screening surface of the vibrating screening component is inclined vertically. The screening chamber has a plastic discharge port 4 communicating with the outside and the lower inclined end of the screening surface, and a copper particle discharge port 5 communicating with the outside and the upper inclined end of the screening surface.
[0019] This utility model has a simple structure, reasonable design and low cost. It integrates the crushing component and the vibrating screening component in the same housing 1. The material particles crushed by the crushing component can fall directly into the vibrating screening component for screening, reducing dust and material particle leakage, effectively reducing the overall size of the copper granulator, reducing equipment cost, and meeting the operational needs of small metal recycling plants with limited funds and space.
[0020] Furthermore, the crushing assembly can directly adopt existing common crushing structures. In this embodiment, the specific structure of the crushing assembly is as follows: the crushing assembly includes a crushing shaft 6 rotatably connected in the crushing chamber, and a moving blade 7 disposed on the outer wall of the crushing shaft 6. A fixed blade 8 that can cooperate with the moving blade 7 is fixed on the inner wall of the crushing chamber. A filter screen 9 is arranged vertically between the crushing shaft 6 and the crushing feed inlet 3 in the crushing chamber. The filter screen 9 has an arc-shaped structure and is arranged around the outer periphery of the crushing shaft 6 and the moving blade 7. At the same time, three open blade slots are evenly distributed circumferentially on the outer wall of the crushing shaft 6 and arranged along the axial direction of the crushing shaft 6. The moving blade 7 is also provided with three slots and is fixed in the corresponding open blade slots. Several adjusting slots are opened on the moving blade 7 along the axial direction perpendicular to the crushing shaft 6. The tail end of the fastener passes through the adjusting slot and is screwed into the open blade slot to realize the fixed connection between the moving blade 7 and the open blade slot and the relative displacement adjustment.
[0021] Furthermore, considering the different vibration amplitudes of copper particles and plastic particles on the vibrating screening assembly, in order to prevent plastic particles from vibrating upwards and being discharged from the copper particle outlet 5, thus affecting the purity of the copper particle screening, the crushing and feeding port 3 is inclined towards the plastic outlet 4.
[0022] Furthermore, in this embodiment, the specific structure of the vibration screening assembly is as follows: the vibration screening assembly includes a screening vibration mesh plate 10 that is tilted up and down on the screening chamber, and a vibration motor assembly 11 fixed on the housing 1. The screening action surface is the upper surface of the screening vibration mesh plate 10. The vibration motor assembly 11 is connected to the screening vibration mesh plate 10 through a crank 12, and the vibration motor assembly 11 drives the screening vibration mesh plate 10 to vibrate through the crank 12.
[0023] In order to effectively remove dust from the screening chamber, an air supply duct 13 and a screening fan 14 are provided on the housing 1 below the screening vibrating screen plate 10. The upper port of the air supply duct 13 covers the mesh directly below the screening vibrating screen plate 10, and the lower port of the air supply duct 13 is connected to the air outlet of the screening fan 14. An air supply fan is provided inside the housing 1. The air intake end of the air supply fan is connected to the screening chamber through an air intake duct, and the corresponding port of the air intake duct is opened above the screening vibrating screen plate 10. The air outlet of the air supply fan is connected to the outside through an exhaust duct, and a filter bag is provided at the outer port of the exhaust duct.
[0024] Meanwhile, in order to prevent the copper particles from jumping too much during vibration conveying and splashing at the copper particle outlet 5, which would increase the difficulty of copper particle recycling and cause copper particle waste that cannot be effectively recycled, a limiting screening plate 15 is provided on the screening cavity located directly above the inclined upper end of the screening vibration screen plate 10. The limiting screening plate 15 has a limiting part 16 and a passing part 17 arranged along the inclined direction of the screening vibration screen plate 10. The passing part 17 and the screening vibration screen plate 10 form a conveying channel for the copper particles to pass through through vibration. The limiting part 16 is connected to the side of the passing part 17 away from the copper particle outlet 5, and the limiting part 16 can prevent the material particles from vibrating and passing over the limiting part 16.
[0025] Considering that some copper particles might slide directly into the plastic outlet 4 when falling from the crushing chamber into the screening chamber, a limiting step surface 18 is provided on the screening chamber between the plastic outlet 4 and the inclined lower end of the screening vibrating screen 10. The limiting step surface 18 and the upper surface of the screening vibrating screen 10 form a stepped depression that prevents material particles from continuing to vibrate and be conveyed, thus achieving accumulation. That is, material particles accumulate at the stepped depression, ensuring that copper particles do not directly exit from the plastic outlet 4 and move upwards under vibration, while plastic particles continue to accumulate at the stepped depression until the accumulation height is higher than the stepped depression before entering the plastic outlet 4.
[0026] The above embodiments are only one of the preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes made in accordance with the shape, structure and principle of this utility model should be covered within the protection scope of this utility model.
