Description

Technical Field

[0001] The present invention relates to a sorting method of a sorter, and particularly to an iron sorter and its installation and sorting method. Background Art

[0002] In the systematic production of large-scale pre-baked anodes for aluminum, the raw materials used are: petroleum coke, spent anodes, etc., and granular materials or fine powders of different particle sizes. After being processed through different processes to meet the required dimensions for use, they are respectively transported and stored in corresponding bins, so as to be mixed evenly according to the set formula and then used for production. Since the production processes of the above various materials in processing and transportation are long, various iron substances can be mixed into the materials. At the same time, during the maintenance operations of process equipment and facilities, it is also inevitable that various iron substances are artificially mixed into the materials. Through long-term production practice, the iron substances mixed into the materials range from steel plates, bolts, and welding electrodes to iron pins and iron powders. They can be said to have different sizes and shapes. Even some materials contain encapsulated and permeable iron substances. Against the background of large-scale continuous production with large amounts of material processing and transportation, it is simply impossible to meet the need for scientific iron removal by relying on manual labor. And the various iron substances mixed in not only affect the quality indicators of pre-baked anodes and the quality of downstream electrolytic aluminum and related aluminum products, but especially pose a serious hidden danger of damage to the entire machine equipment for the safe operation of high-precision imported equipment such as continuous kneaders and continuous batching scales in the green anode manufacturing process. At present, the common method in the same industry is to suspend and install an electromagnetic iron remover above the belt conveyor. However, for a large-scale and multi-process production system, the limitations of this single iron removal method simply cannot cover the iron removal of the entire process. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: to overcome the deficiencies of the prior art and provide an iron sorter and its installation and sorting method that are novel in design and reasonable in structure, and can achieve online screening and separation of the mixed iron substances in each technological link such as the processing and transportation of pre-baked anode materials in large-scale continuous production, so as to improve the quality of pre-baked anodes and the quality of downstream electrolytic aluminum and related aluminum products.

[0004] The technical solution adopted by the present invention to solve the technical problem is:

[0005] An installation and sorting method of an iron sorter includes the following steps:

[0006] S1: Assemble the iron sorter. First, weld a quadrilateral frame, and then weld a U-shaped connecting rod, ensuring that the opening of the U-shaped connecting rod faces upward. Drill fourth bolt holes on the first and third support rods of the quadrilateral frame, and drill a first bolt hole at the lower part of the U-shaped connecting rod;

[0007] S2: Drill second bolt holes symmetrically at both ends of the opening on the inverted U-shaped wear-resistant stainless steel plate. The positions of the second bolt holes correspond to the positions of the first bolt holes on the U-shaped connecting rod.

[0008] S3: After drilling the second bolt holes, inlay the high-magnetic-force magnet on the U-shaped connecting rod.

[0009] S4: Wrap the inlaid high-magnetic-force magnet with the inverted U-shaped wear-resistant stainless steel plate. After complete wrapping, use the second bolt holes on the inverted U-shaped wear-resistant stainless steel plate and the first bolt holes on the U-shaped connecting rod to fix the inverted U-shaped wear-resistant stainless steel plate, the high-magnetic-force magnet, and the U-shaped connecting rod together through the first connecting bolt.

[0010] S5: Fabricate a "ji"-shaped fixing steel plate, drill third bolt holes on the fixing steel plate. The sizes of the third bolt holes match the sizes of the fourth bolt holes. The fixing steel plate is connected and fixed to the frame through the third bolt holes and the fourth bolt holes on the frame by the second connecting bolt.

[0011] S6: Install the assembled iron separator between the material accumulation partitions inside the discharge pipe. The distance between every two iron separators is 1 m, and the last separator is installed at the outlet of the discharge pipe.

[0012] S7: After installing the iron separator, set the material flow rate so that the thickness of the material during flow is lower than the height of the high-magnetic-force magnet.

[0013] S8: Turn on the power. The belt conveyor transports the material to the inlet of the discharge pipe. An electromagnetic iron remover is installed above the belt conveyor to remove iron from the material for the first time.

[0014] S9: The material that has been de-ironed by the electromagnetic iron remover enters the inside of the discharge pipe under the transportation of the conveyor. The separators inside the discharge pipe shunt the material and perform the second iron removal at the same time. The shunting can separate the iron contained in the material inside the material. Multiple iron separators are arranged inside the discharge pipe, and multiple shuntings are performed, so as to stir the material multiple times and make the iron separation more thorough.

[0015] S10: After multiple shunt separations inside the discharge pipe, the iron separator installed at the outlet of the discharge pipe performs the last shunt separation to completely separate the iron in the material.

[0016] S11: The sorted material enters the next process.

[0017] S12: After sorting is completed, turn off the power and clean the surface of the iron separator to completely clean the adsorbed iron.

[0018] An iron separator, comprising a frame and a high-magnetic-force magnet. The frame includes a first support rod, a second support rod, a third support rod, and a fourth support rod. The first support rod, the second support rod, the third support rod, and the fourth support rod are sequentially and vertically connected end to end. The first support rod is parallel to the third support rod, and the second support rod is parallel to the fourth support rod. A connecting rod is arranged between the second support rod and the fourth support rod, and both ends of the connecting rod are respectively connected to the second support rod and the fourth support rod. A U-shaped groove is arranged on the connecting rod, and the opening of the U-shaped groove faces upward. A first bolt hole is arranged at the lower part of the connecting rod. The high-magnetic-force magnet is embedded in the U-shaped groove. An inverted-U-shaped wear-resistant stainless steel plate is arranged on the periphery of the high-magnetic-force magnet. Second bolt holes are symmetrically arranged at both ends of the opening of the inverted-U-shaped wear-resistant stainless steel plate. After the inverted-U-shaped wear-resistant stainless steel plate completely wraps the high-magnetic-force magnet, a first connecting bolt uses the first bolt hole and the second bolt hole to fix the inverted-U-shaped wear-resistant stainless steel plate, the high-magnetic-force magnet, and the connecting rod together.

[0019] "Ji"-shaped fixing steel plates are symmetrically arranged at both ends of the first support rod and the third support rod. A third bolt hole is arranged on the upper end surface of the fixing steel plate. Fourth bolt holes with the same specifications as the third bolt hole are arranged on the first support rod and the third support rod at positions corresponding to the third bolt hole. The third bolt hole and the fourth bolt hole respectively connect the fixing steel plate with the first support rod and the third support rod by using a second connecting bolt. The frame is welded to a conveyor for conveying materials that need to separate iron by using the two side wings of the fixing steel plate.

[0020] The first support rod, the second support rod, the third support rod, and the fourth support rod are all made of stainless steel square steel and are on the same horizontal plane. The heights of the first support rod, the second support rod, the third support rod, and the fourth support rod are all 5 cm. After the first support rod, the second support rod, the third support rod, and the fourth support rod are vertically connected end to end, they enclose an accumulation grid.

[0021] At least two connecting rods are provided, and the first bolt hole penetrates through both ends of the connecting rod.

[0022] The positive and beneficial effects of the present invention are:

[0023] 1. In the present invention, the inverted-U-shaped wear-resistant stainless steel plate completely wraps the high-magnetic-force magnet. Without affecting its magnetic force, it can also prevent the direct contact between the high-magnetic-force magnet and steel during the installation and use process, scientifically avoiding the attenuation of the magnetic force.

[0024] 2. In the present invention, a plurality of connecting rods are provided. Each connecting rod is provided with a high-magnetic-force magnet wrapped with an inverted-U-shaped wear-resistant stainless steel plate, and iron products can be adsorbed on the circumference of the high-magnetic-force magnet. This not only realizes a scientific and reasonable diversion of the material flow rate but also increases the contact area between the material and the iron separator, making the on-line separation of iron substances more sufficient and thorough.

[0025] 3. In the present invention, the inverted-U-shaped wear-resistant stainless steel plate and the "Ji"-shaped fixing steel plate are preformed and then installed with bolts. This allows for random replacement after wear without damaging the high-magnetic-force permanent magnet and the frame, reducing the replacement frequency of the high-magnetic-force permanent magnet and the frame, improving production efficiency, reducing production input, and saving production time.

[0026] 4. The setting of the material accumulation grid in the present invention can form a material accumulation buffer layer here, avoiding the friction and impact of the flowing material on the bottom plate of the conveyor where this device is located, and achieving the extension of the service life of the target body and this device.

[0027] 5. The present invention is novel in design and reasonable in structure. It realizes on-line screening and separation of the mixed iron substances in each technological link such as the processing and transportation of pre-baked anode materials for large-scale continuous production, thereby improving the quality of pre-baked anodes and the quality of downstream electrolytic aluminum and related aluminum products. At the same time, it also maximally avoids the safety hazards caused by iron substances to high-precision imported equipment such as continuous kneading machines and continuous batching scales.

[0028] 6. The present invention can be flexibly processed, manufactured, and arranged according to the operating conditions, and can be widely and scientifically applied to any required part. Under the same operating conditions, it can achieve the complete separation of various physical iron substances mixed in the material. For a medium-sized pre-baked anode company, it can increase efficiency by more than 3 million yuan per year by improving product quality. Moreover, since the present invention realizes the complete separation and filtration of the iron substances mixed in the material, it provides strong guarantee for the safe operation of high-precision process equipment such as continuous kneading machines and continuous batching scales in the green anode manufacturing system, avoiding direct accident costs of more than 4.8 million yuan each time. It not only has wide applicability but also can bring good economic benefits. BRIEF DESCRIPTION OF THE DRAWINGS
