[0002] With the rapid development of metallurgical industry, the amount of metallurgical waste is increasing year by year, how to effectively handle and reuse these waste has become an important issue in the field of environmental protection. Metallurgical waste usually includes metal chips, slag, oxides and various residues generated during smelting. These waste contains recyclable metals such as iron, aluminum, copper, etc., and impurities such as oxides, non-metallic materials, etc. that are difficult to handle. Therefore, how to efficiently separate recyclable metal materials from these mixed waste and reduce the discharge of useless waste has become a major challenge for the metallurgical industry.

[0003] The existing metallurgical waste treatment method mostly relies on traditional physical crushing and screening process, although it can preliminarily process the waste to a certain extent, but there are the following main problems:

[0005] 2. High energy consumption and cost: The traditional separation equipment has complex structure and cumbersome operation, and when processing a large amount of waste, the equipment has high energy consumption, and the maintenance and wear cost of the equipment is high, which increases the production cost of enterprises.

[0006] 3. Environmental pressure: A large amount of waste that has not been effectively separated is directly discharged or stacked, which is easy to cause secondary pollution to the environment, especially harmful substances (such as heavy metals and toxic oxides) in the waste, if not treated, will cause serious pollution to the soil and water source.

[0007] Therefore, to develop a simple structure, high efficiency and intelligent separation function equipment to effectively treat metallurgical waste, improve resource recovery rate, reduce enterprise operating cost and reduce environmental pollution, is one of the problems to be solved in the metallurgical industry.

[0032] Equipment structure:

[0033] The composite separation equipment of metallurgical waste recycling includes feeding port 1, crushing device, magnetic separation device, driving device, first collecting mechanism and second collecting mechanism from top to bottom.Specific structure is as follows:

[0034] Feeding port 1:

[0035] Feeding port 1 is arranged at the top end of crushing device, for the input of metallurgical waste.Metallurgical waste enters crushing device inside through feeding port, ready for subsequent crushing treatment.

[0036] Crushing device:

[0037] Crushing device includes shell 2, support frame 201, discharge port 202, first shaft 203 and crushing roller 204.The main function of crushing device is to preliminarily crush large pieces of metallurgical waste, for subsequent separation.

[0038] Shell 2 is fixed on the upper end of second collecting mechanism through support frame 201, the top of shell is connected with feeding port 1, and the bottom is provided with discharge port 202.

[0039] Crushing roller 204 is installed in shell 2 through first shaft 203, and is driven to rotate by driving device, and crushing roller 204 crushes metallurgical waste into smaller particles.The crushed waste falls into magnetic separation device through discharge port 202.

[0040] Driving device:

[0041] Driving device includes motor 3 and transmission belt 301, for providing power for crushing device and magnetic separation device.

[0042] Motor 3 is installed on second collecting mechanism, and drives first shaft 203 in crushing device and second shaft 402 in magnetic separation device to rotate through transmission belt 301.

[0043] To prevent metallurgical waste from causing damage during the operation of transmission belt, protective shell 302 is arranged outside transmission belt 301, to ensure the operation safety of equipment.

[0044] Magnetic separation device:

[0045] The magnetic separation device is composed of a magnetic disc 4, a push rod 401 and a second rotating shaft 402, which is used to separate ferromagnetic materials from the crushed waste materials.

[0046] The magnetic disc 4 is installed on the first collecting mechanism through the second rotating shaft 402 and rotates under the drive of the motor 3. The center of the magnetic disc 4 is a convex arc surface structure. When the waste materials pass through the magnetic disc 4, the ferromagnetic materials are adsorbed on the surface of the magnetic disc 4, and the non-ferromagnetic materials slide into the second collecting mechanism.

[0047] The push rod 401 is installed above the magnetic disc 4, which is used to uniformly distribute the waste materials on the magnetic disc 4 and help separate the waste materials during the rotation of the magnetic disc 4.

[0048] First collecting mechanism:

[0049] The first collecting mechanism is used to collect the ferromagnetic materials adsorbed by the magnetic disc. The mechanism includes a ferromagnetic material collecting hopper 5, a discharge port 501, a first storage area 502, a first material taking door 503, a scraper 504 and an inclined table 505.

[0050] The ferromagnetic materials enter the collecting hopper 5 through the magnetic disc 4, and the materials are scraped into the collecting hopper 5 by the cooperation of the scraper 504 and the rotation of the magnetic disc 4.

[0051] The bottom of the collecting hopper 5 is provided with an inclined table 505, which is used to guide the ferromagnetic materials into the discharge port 501, so as to enter the first storage area 502.

[0052] When the first storage area 502 is full, the operator can take out the collected ferromagnetic materials through the first material taking door 503.

[0053] Second collecting mechanism:

[0054] The second collecting mechanism is provided with a second storage area 601 and a second material taking door 601, which is used to collect the non-ferromagnetic materials that slide off the magnetic disc 4.

[0056] Device working process:

[0057] The metallurgical waste materials enter the crushing device from the feeding port 1. The crushing roller 204 starts to rotate under the drive of the motor 3, crushing the large waste materials into smaller particles. The crushed materials fall into the magnetic separation device through the discharge port 202.

[0058] The magnetic disc 4 in the magnetic separation device rotates under the driving of the second rotating shaft 402, and adsorbs the ferromagnetic material in the waste material. The arc surface design of the surface of the magnetic disc 4 ensures that the non-ferromagnetic material can smoothly slide to the second collecting mechanism.

[0059] In the magnetic separation process, the ferromagnetic material is adsorbed on the magnetic disc 4 and enters the ferromagnetic material collecting hopper 5 with the help of the lever 401. The ferromagnetic material in the ferromagnetic material collecting hopper 5 enters the discharge port 501 through the inclined table 505 and is stored in the first storage area 502.

[0060] The non-ferromagnetic material is not adsorbed when passing through the magnetic disc, and directly falls into the second storage area 601 for subsequent processing. The operator can collect and process the non-ferromagnetic material through the second material taking door 601.

[0061] Through the specific operation of the above embodiment, the device of the utility model can efficiently separate the ferromagnetic material and the non-ferromagnetic material in the metallurgical waste material, and reduces the difficulty and cost of manual sorting. The device has compact structure, simple operation, and can be adjusted according to different waste treatment requirements. In addition, each component of the device can be maintained and replaced individually, greatly improving the service life and economic benefit of the device.

[0062] The device of the utility model can not only effectively separate valuable metals in metallurgical waste material, but also reasonably process useless waste material, and has important environmental protection and economic benefits.

[0063] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same and similar parts of each embodiment can be referred to each other.
