Description

Technical Field

[0001] This utility model relates to the field of metallurgical waste treatment, and more specifically to a high-efficiency and energy-saving slag treatment device. Background Technology

[0002] With the rapid development of the metallurgical industry, the amount of metallurgical waste generated is increasing year by year. How to effectively treat and reuse this waste has become an important issue in the field of environmental protection. Metallurgical waste typically includes metal scrap, slag, oxides, and various residues generated during the smelting process. These wastes contain both recyclable metals, such as iron, aluminum, and copper, and difficult-to-treat impurities, such as oxides and non-metallic materials. Therefore, how to efficiently separate recyclable metal materials from these mixed wastes and reduce the emission of useless waste has become a major challenge facing the metallurgical industry.

[0003] Existing methods for treating metallurgical waste mostly rely on traditional physical crushing and screening processes. While these methods can provide some initial treatment of the waste, they suffer from the following main problems:

[0004] 1. Low separation efficiency: Because the metallic and non-metallic components in the waste are tightly mixed, traditional screening methods are difficult to effectively separate ferromagnetic and non-ferromagnetic materials, resulting in low resource recovery rate.

[0005] 2. High energy consumption and high cost: Traditional separation equipment has a complex structure and is cumbersome to operate. When processing large amounts of waste, the equipment consumes a lot of energy and has high maintenance and wear costs, which increases the production costs of enterprises.

[0006] 3. Environmental pressure: The direct discharge or accumulation of large amounts of unseparated waste can easily cause secondary pollution to the environment. In particular, harmful substances in the waste (such as heavy metals and toxic oxides) can cause serious pollution to soil and water sources if they are not treated.

[0007] Therefore, developing a simple, efficient, and intelligent separation device to effectively treat metallurgical waste, improve resource recovery rates, reduce enterprise operating costs, and reduce environmental pollution is one of the urgent problems that the metallurgical industry needs to solve.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1

[0042] like Figure 1 and Figure 2 As shown in the figure, this embodiment details the specific structure and working process of a high-efficiency and energy-saving slag treatment device.

[0043] Specific structure of the equipment

[0044] 1. Broken parts

[0045] Crushing barrel 1: The crushing barrel is a hollow cylindrical structure, and its interior is used to contain and process slag. The crushing roller 101 inside the crushing barrel achieves the initial crushing of the slag.

[0046] Crushing roller 101: The crushing roller is installed inside the crushing barrel 1 and is connected to the motor 6 via a rotating shaft 601. The motor drives the crushing roller to rotate, crushing the slag entering the crushing barrel.

[0047] Crushing teeth 103: These are staggered between the outer wall of the crushing roller 101 and the inner wall of the crushing barrel 1, which can enhance the crushing force and improve the crushing efficiency. The serrated crushing teeth increase the contact area, enabling the slag to be efficiently crushed into the required particle size.

[0048] 2. Anti-clogging design

[0049] Inclined platform 102: Located at the upper end of crushing roller 101, its inclined structure prevents slag from accumulating on top of crushing roller 101 during the crushing process. Guided by the inclined platform 102, the slag will slide off naturally, avoiding affecting the continuous operation of the equipment.

[0050] 3. Thermal Management Section

[0051] Heat insulation cover 2: Installed at the top of the crushing barrel 1, heat insulation cover 2 is used to prevent the heat generated during the crushing process from dissipating outward, reducing energy loss and improving thermal energy utilization efficiency. Heat insulation cover 2 adopts a double-layer structure and is filled with heat insulation material inside to further enhance the heat insulation effect.

[0052] Waste heat collection tank 3: Fixedly installed on the outer wall of crushing tank 1. It is equipped with waste heat collection blades 301 inside. The blades have a spiral structure to increase the contact area with the heat of the slag and accelerate heat absorption.

[0053] Heat transfer pipe 302: connected to waste heat collection tank 3, used to transfer the absorbed heat to an external system through circulating liquid, so as to realize the recycling of waste heat.

[0054] 4. Slag Collection and Screening Section

[0055] Screen plate 5: Installed between crushing drum 1 and slag collection drum 4. The screen plate is used to screen the crushed slag by particle size, so that slag that meets the particle size requirements enters the slag collection drum 4, while slag that does not meet the requirements will continue to remain in the crushing drum for further processing. Screen plate 5 is linked to motor 6, and the vibration screening is achieved by driving motor 6.

[0056] Slag Collection Bucket 4: Used to store crushed and screened slag for centralized processing. It has a material handling door 401 on one side, allowing users to periodically clean the slag and prevent excessive accumulation from affecting equipment operation.

[0057] 5. Protection and Maintenance Design

[0058] Isolation sleeve 403: Installed on the outside of motor 6, it protects the motor from slag and high temperatures, ensuring normal operation of the motor. The isolation sleeve is detachable, facilitating motor inspection and maintenance.

[0059] Turntable 402: Installed on the upper end of isolation sleeve 403, its rotation prevents slag from accumulating on isolation sleeve 403. The continuous rotation of turntable 402 removes the attached slag, avoiding equipment blockage and ensuring stable operation of the equipment.

[0060] Equipment working process

[0061] 1. Slag Crushing

[0062] Motor 6 drives shaft 601 to rotate crushing roller 101. Crushing teeth 103 on crushing roller 101 interlock with crushing teeth 103 on the inner wall of crushing barrel 1, crushing slag into smaller particles. During the crushing process, inclined platform 102 guides slag down to prevent it from sticking to the top of crushing roller 101.

[0063] 2. Screening and Collection

[0064] The crushed slag is screened through screen plate 5, and qualified particles enter slag collection bin 4. Screen plate 5 is driven by motor 6 to vibrate continuously, improving screening efficiency. The slag in collection bin 4 can be cleaned periodically through discharge gate 401.

[0065] 3. Waste heat recovery

[0066] The heat generated during the crushing process is conducted to the waste heat collection tank 3 through the outer wall of the crushing barrel 1. The waste heat collection blades 301 quickly absorb the heat and transfer it to the external system through the heat transfer pipe 302 to heat other equipment or systems and improve energy efficiency.

[0067] 4. Prevention and Maintenance

[0068] The isolation sleeve 403 protects the motor 6 from high temperatures and slag. The rotation of the turntable 402 prevents slag from accumulating on the surface of the isolation sleeve 403, ensuring long-term stable operation of the equipment. Furthermore, both the isolation sleeve 403 and the turntable 402 are detachable for easy maintenance and repair.

[0069] In summary, this utility model provides a highly efficient and energy-saving slag treatment device with a reasonable structure, complete functions, and simple operation. Through efficient crushing, waste heat recovery, and anti-clogging design, it achieves efficient slag treatment and energy utilization. This device is suitable for the slag treatment needs in the metallurgical industry and has high practical value and promising prospects for promotion.
