[0045] Specifically, one side of the mounting seat 201 is connected with the second motor 205 via bolts, and the output shaft of the second motor 205 is fixedly connected to the main shaft of the auxiliary roller 203 via a coupling.

[0046] Among them, a second motor 205 is added to the side wall of the mounting seat 201 and connected to the main shaft of the auxiliary roller 203. The power of the second motor 205 is turned on by the control device. The second motor 205 drives the auxiliary roller 203 to rotate, and then drives the main roller 202 to rotate through the belt 204, continuously absorbing the magnetic material, and conveying the material to the rear storage area through the belt.

[0047] Furthermore, a latch rod 206 is inserted into the side wall of the mounting seat 201 , and the end of the latch rod 206 is inserted into the middle of the latch hole of the side wall of the connecting member 106 . A retaining edge structure matching the mounting seat 201 is installed at the bottom of the connecting member 106 .

[0048] Among them, a latch rod 206 is added to the side wall of the mounting seat 201 to connect with the connecting piece 106, and the latch rod 206 is installed in different through holes on the side wall of the connecting piece 106. The height of the mounting seat 201 can be adjusted to adapt to adjusting the distance between the mounting seat 201 and the base 104, and to adapt to the refining pretreatment of copper materials in different states.

[0053] In summary, the present application adds components such as a main roller 202 and an auxiliary roller 203 connected by a mounting base 201 for magnetic separation of the scrap copper raw materials transported on the conveyor belt 105. The magnetic material will be adsorbed on the surface of the belt 204 by the main roller 202, and driven by the auxiliary roller 203 to be transported to the storage device, and transported separately from the conveyor belt 105, so as to facilitate the subsequent transfer and processing of the magnetic material.

[0054] Example 3

[0055] Reference Figure 1-5 , which is the third embodiment of the present invention, is different from the second embodiment in that a screening component 300 of a scrap copper refining device is provided.

[0056] Specifically, the screening assembly 300 includes a shell 301, a hopper 302 installed on the side wall of the shell 301, and a discharge chute 303 installed at the end of the shell 301. The side wall of the shell 301 is connected to the end of the bracket 101 by bolts, one side of the discharge chute 303 is fixedly connected to the bracket 101 by bolts, and the lower end of the discharge chute 303 extends to the bottom of the bracket 101.

[0057] Among them, the shell 301 is a perforated groove structure, which is used to screen the waste copper material, so that large particles of material fall along the end surface of the shell 301, and are collected by the discharge chute 303 for further processing. Small particles of material will fall from the shell 301 onto the conveyor belt 105 installed in the middle of the bracket 101, and are transported backward by the conveyor belt 105 for magnetic separation treatment. The hopper 302 is used to guide the material to ensure that the material can be stably transported to the side wall of the shell 301. The shell 301 is installed at the end of the bracket 101 to pre-treat the material, improve the magnetic separation efficiency, effectively remove impurities in the waste copper raw materials, and realize the recovery of high-purity copper. At the same time, large particles of harmful substances in the waste copper are isolated, which is convenient for refining the copper raw materials with flotation equipment, reducing the pollution of waste copper to the environment, saving limited metal mineral resources, and improving the recovery efficiency. At the same time, it also reduces the demand for incineration and landfill of waste copper, fundamentally reducing the generation of waste and damage to the environment.

[0058] Furthermore, through groove structures are provided at equal intervals in the middle of the shell 301 , and a scraper 304 is slidably mounted on the inner wall of the lower end of the shell 301 , and the side wall strips of the scraper 304 are inserted into the inner side of the through groove in the middle of the shell 301 .

[0059] A through slot is provided in the middle of the shell 301 for screening materials, and a scraper 304 is added at the bottom of the shell 301 for scraping the materials stuck in the middle of the through slot of the shell 301 to avoid the materials from clogging the shell 301 and maintain the normal use of the shell 301.

[0060] Furthermore, a push rod 305 is movably inserted in the middle position of the end of the shell 301, and the end of the push rod 305 is fixedly connected to the side wall of the scraper 304 by bolts.

[0061] A push rod 305 is installed in the middle of the shell 301 to connect with the scraper 304 , so as to facilitate the scraper 304 to move along the shell 301 to clean the through groove inside the shell 301 .

[0062] Preferably, a first motor 306 is fixedly mounted on the end side wall of the housing 301 , and a gear meshing with the teeth of the side wall of the push rod 305 is mounted on the end of the output shaft of the first motor 306 .

[0063] Among them, a first motor 306 with gears is installed on the side wall of the shell 301, and the first motor 306 is driven to operate by a control device. The first motor 306 can cooperate with the gear to drive the top rod 305 to move along the side wall of the shell 301, thereby driving the scraper 304 to operate on the bottom side wall of the shell 301.

[0064] During use, materials are added from the hopper 302 into the shell 301. Small particles of materials will fall along the through groove inside the shell 301 onto the conveyor belt 105 installed in the middle of the bracket 101, and will be transported backward by the conveyor belt 105 for magnetic separation. Large particles of materials will fall along the side wall of the shell 301 into the discharge chute 303, and will be transported to the storage device via the discharge chute 303. Then, materials are transferred according to demand. When the inside of the shell 301 is clogged with a lot of materials that affect its use, the control device turns on the power of the first motor 306, and the first motor 306 cooperates with the gear to drive the push rod 305 to move along the side wall of the shell 301, thereby driving the scraper 304 to run on the bottom side wall of the shell 301, scraping out the materials stuck in the through groove inside the shell 301, and keeping the shell 301 unobstructed.

[0065] In summary, the shell 301 is a perforated groove structure, which is used to screen the waste copper materials, so that large particles of materials fall along the end surface of the shell 301, and are collected by the lower chute 303 for further processing. Small particles of materials will fall from the shell 301 onto the conveyor belt 105 installed in the middle of the bracket 101, and are transported backward by the conveyor belt 105 for magnetic separation. The hopper 302 is used to guide the materials to ensure that the materials can be stably transported to the side wall of the shell 301. The shell 301 is installed at the end of the bracket 101 to pre-treat the materials, improve the magnetic separation efficiency, and effectively remove impurities in the waste copper raw materials. The high-purity copper can be recycled, and the large particles of harmful substances in the waste copper can be isolated, so that the copper raw materials can be refined with the flotation equipment, which reduces the pollution of the waste copper to the environment and saves the limited metal mineral resources. By improving the recycling efficiency, the demand for the incineration and landfill of waste copper can be reduced, which fundamentally reduces the generation of waste and the damage to the environment. A through groove is provided in the middle of the shell 301 for screening the materials, and a scraper 304 is added at the bottom of the shell 301 for scraping the materials stuck in the middle of the through groove of the shell 301, so as to avoid the materials blocking the shell 301 and maintain the normal use of the shell 301.
