A scrap steel processing and recycling equipment and recycling process

Abstract

The invention relates to the technical field of scrap steel processing, and in particular to a scrap steel processing and recycling device and a recycling process. The cleaned scrap steel is crushed by a crushing unit, and the obtained small-volume crushed materials are conveyed by a conveying unit. When conveyed to the rightmost end, intermittent feeding is performed, and finally the crushed materials are melted by a smelting unit. In the above process, intermittent feeding is performed through a gap feeding part, and the crushed materials can be fed in batches, which is convenient for rapid melting of the crushed materials. At the same time, the crushed materials in the smelting furnace are magnetically guided by a magnetic suction component, so that the crushed materials can move toward the wall surface where the magnetic suction component is located. The closer the crushed materials are to the heating layer, the faster they melt. Since the movement of the crushed materials in the molten steel liquid will drive the liquid flow, the heating and melting of the crushed materials are further promoted, so that the overall smelting process is faster and more sufficient, and the smelting efficiency of the scrap steel is improved.

Description

Technical Field

[0001] The present invention relates to the technical field of scrap steel processing, and in particular to scrap steel processing and recycling equipment and a recycling process. Background Art

[0002] Scrap steel refers to scrapped or obsolete steel products, mainly including surplus materials and waste products generated during the production process due to the end of their service life, as well as obsolete products updated due to technological progress or backward economic indicators. The generation of scrap steel involves various industries and production fields in society, such as machinery and equipment, transportation vehicles, agricultural machinery, buildings, military supplies, daily necessities, etc.

[0003] The recycling and treatment of scrap steel is of great significance. The recycling of scrap steel can not only effectively save resources and reduce environmental pollution, but also can be reused through smelting and other methods, thereby saving production costs and improving resource utilization efficiency.

[0004] In the prior art, when smelting scrap iron and steel, a fixed amount of scrap iron and steel is usually put into a smelting furnace for smelting at one time. When the accumulated scrap iron and steel is melted at a fixed time, the obtained molten liquid may contain scrap iron and steel that has not been completely melted. It takes a long time for the accumulated scrap iron and steel to be completely melted.

[0014] In summary, the present invention includes at least one of the following beneficial technical effects:

[0015] 1. The present invention provides a scrap iron and steel processing and recycling equipment and a recycling process. The cleaned scrap iron and steel is crushed by a crushing unit, and the obtained small-volume crushed materials are conveyed by a conveying unit. When conveyed to the rightmost end, intermittent unloading is performed, and finally the crushed materials are melted by a smelting unit.

When the weight of the crushed materials accumulated in the loading frame is greater than the counterweight, the loading frame will tilt to the right. At this time, the opening and closing door will open due to the tilt angle and the falling direction of the crushed materials, realizing intermittent batch unloading, which is conducive to the full melting of the crushed materials.

The bottom slider 41 is symmetrically slidably arranged on the upper end of the mounting platform 1 and located on the right side of the conveying unit 3. The positioning bracket 42 is fixedly installed on the upper end of the bottom slider 41. The connecting shaft 43 is rotatably connected to the positioning bracket 42. The smelting furnace 44 is fixedly installed between the connecting shafts 43. The smelting furnace 44 is provided with a magnetic guide part 45. The rear end of the rear positioning bracket 42 is fixedly installed with a motor 46 through a motor seat. The output shaft of the motor 46 is fixedly connected to the connecting shaft 43 on the rear side.

[0035] See also Figure 5 , Figure 7 and Figure 8 The smelting furnace 44 includes an insulating cylinder 441, a feeding funnel 442, a heating layer 443, an inner lining layer 444, a discharging cylinder 445 and an arc guide groove 446. The insulating cylinder 441 is fixedly installed between the connecting shafts 43. The feeding funnel 442 is fixedly installed on the upper end of the insulating cylinder 441. The inner wall of the insulating cylinder 441 is provided with a heating layer 443. The inner wall of the heating layer 443 is provided with an inner lining layer 444. A discharging cylinder 445 is fixedly installed on the upper side of the right end of the insulating cylinder 441. The discharging cylinder 445 is connected to the inner lining layer 444. The outer wall of the insulating cylinder 441 is symmetrically provided with an arc guide groove 446.

[0036] See also Figure 5 , Figure 7 and Figure 8 The magnetic guide part 45 includes an extended positioning plate 451, a driving component 452, a fixed collar 453, an installation gear ring 454, a connecting column 455, a longitudinal guide groove 456 and a magnetic attraction component 457. The left end of the heat insulating cylinder 441 is fixedly installed with extended positioning plates 451 at the upper and lower ends respectively, and a driving component 452 is arranged between the extended positioning plates 451. A fixed collar 453 is symmetrically fixedly installed at the outer end of the heat insulating cylinder 441 and located between the extended positioning plates 451. The fixing collar 453 is rotatably connected to the installation gear ring 454, and connecting columns 455 are symmetrically fixedly installed between the installation gear rings 454. A longitudinal guide groove 456 is opened on the connecting column 455, and a magnetic attraction component 457 is slidably arranged in the longitudinal guide groove 456. The magnetic attraction component 457 slides with the arc guide groove 446.

[0037] The cleaned scrap steel is crushed by the crushing unit 2, and the obtained crushed materials are conveyed by the conveying unit 3. When conveyed to the rightmost end, intermittent feeding is carried out. The crushed materials falling into the lining layer 444 from the feeding funnel 442 are continuously heated by the heating layer 443 until they are melted. The two mounting gear rings 454 are driven by the driving component 452 to rotate synchronously in the same direction (forward and reverse rotation are performed alternately, with a fast forward rotation speed and a slow reverse rotation speed), and then the mounting gear ring 454 drives the connecting column 455 to rotate synchronously.

[0038] During the process of installing the gear ring 454 for uniform reversal, the magnetic component 457 moves upward along the longitudinal guide groove 456 under the drive of the support column, and slides along the arc guide groove 446, so that the magnetic component 457 performs uniform upward movement on the outer wall of the insulation cylinder 441. Due to the magnetic effect of the magnetic component 457, the fragments in the lining layer 444 can move toward the wall where the magnetic component 457 is located. The closer the fragments are to the heating layer 443, the faster they melt. During the movement, the fragments can drive the molten steel liquid to flow, further promoting the melting of the fragments. As the liquid level of the molten steel liquid gradually rises, the magnetic component 457 rises slowly accordingly, which is used to guide the fragments that intermittently fall into the upper layer, thereby promoting melting.

[0039] After completing the smelting of a batch of scrap steel, the gear ring 454 is installed to rotate forward so that the magnetic suction component 457 returns to the starting point from top to bottom along the arc guide groove 446, and then the bottom slider 41 is controlled to move to the right. After it moves to the specified position and stops, the connecting shaft 43 is driven to rotate by the motor 46, so that the smelting furnace 44 as a whole rotates clockwise by a certain angle, so that the molten steel in the smelting furnace 44 can be poured out from the discharge barrel 445 (the molten steel is poured into the prepared mold for cooling to facilitate subsequent processing).

[0040] See also Figure 1 , Figure 3 and Figure 4 The crushing unit 2 includes a four-legged support frame 21, a square positioning frame 22, a square feed hopper 23, a square discharge hopper 24 and a crushing part 25. The four-legged support frame 21 is fixedly installed on the left side of the upper end of the installation platform 1, and the square positioning frame 22 is fixedly installed on the four-legged support frame 21. The square feed hopper 23 is fixedly installed on the upper end of the square positioning frame 22, and the square discharge hopper 24 is fixedly installed on the lower end of the square feed frame. The crushing part 25 is provided on the square positioning frame 22.

[0041] See also Figure 3 and Figure 4The crushing part 25 includes a crushing roller 251, a knife plate 252, a matching gear 253 and a motor three 254. The crushing roller 251 is symmetrically connected to the front and rear walls in the square positioning frame 22 for rotation. The blades on the two crushing rollers 251 are staggered. Knife plates 252 are evenly arranged on the front and rear walls of the square positioning frame 22. The knife plates 252 and the blades on the adjacent crushing rollers 251 are staggered. The rear end of the crushing roller 251 is fixedly connected to a matching gear 253. The left and right matching gears 253 are meshed with each other. The rear end of the square positioning frame 22 is fixedly installed with a motor three 254 through a motor seat. The output shaft of the motor three 254 is fixedly connected to the matching gear 253 on the left.

[0042] Scrap iron and steel is put into the square positioning frame 22 from the square feed hopper 23, and then the motor 3 254 drives the matching gear 253 to rotate, so that the crushing roller 251 rotates relatively, thereby crushing the scrap iron and steel put therein, and the obtained crushed materials fall from the square discharge hopper 24 onto the conveying unit 3.

[0043] See also Figure 1 , Figure 3 and Fig. 9 The conveying unit 3 includes an elevator 31, a fixed plate 32, a reinforcing rib 33, a fixed support 34, a central round rod 35 and an intermittent unloading part 36. The elevator 31 is fixedly installed on the upper end of the mounting platform 1 and on the right side of the crushing unit 2. The fixed plate 32 is fixedly installed on the right end of the rightmost support frame of the elevator 31. The reinforcing rib 33 fixedly connected to the rightmost support frame of the elevator 31 is symmetrically fixedly installed on the lower end of the fixed plate 32. The fixed supports 34 are symmetrically fixedly installed on the right side of the upper end of the fixed plate 32. A central round rod 35 is fixedly installed between the fixed supports 34, and the intermittent unloading part 36 is rotatably connected to the central round rod 35.

[0044] See also Fig. 9 and Fig.10 The intermittent unloading part 36 includes a positioning connection block 361, a loading frame 362, a counterweight block 363, a connecting round rod 364 and an opening and closing plate 365. The positioning connection block 361 is rotatably connected to the center round rod 35, the loading frame 362 is fixedly installed on the upper end of the positioning connection block 361, the counterweight block 363 is fixedly installed on the left side of the lower end of the loading frame 362, a connecting round rod 364 is fixedly installed between the front and rear side plates of the loading frame 362, and the opening and closing plate 365 is hinged on the connecting round rod 364.

[0045] The crushed materials are transported to the right end by the elevator 31 and fall into the loading frame 362 from the right end. As the crushed materials gradually increase, when the weight of the crushed materials in the loading frame 362 is greater than the weight of the counterweight block 363, the positioning connection block 361 rotates to the right around the central round rod 35, that is, the loading frame 362 tilts to the right so that a batch of crushed materials are poured out from the right end of the loading frame 362; the weight of the counterweight block 363 is set to be constant. When the weight of the crushed materials accumulated in the loading frame 362 is greater than the counterweight block 363, according to the lever principle, the loading frame 362 will tilt to the right. At this time, the opening and closing door will open due to the tilt angle and the falling direction of the crushed materials, realizing intermittent batch unloading, which is helpful for the crushed materials to be fully melted.

[0046] See also Figure 5 and Figure 7 The driving assembly 452 includes a driving gear 4521, a transmission shaft 4522 and a second motor 4523. The opposite end of the extended positioning plate 451 is rotatably connected with the driving gear 4521. The driving gears 4521 are fixedly connected through the transmission shaft 4522. The upper end of the extended positioning plate 451 on the upper side is fixedly installed with a second motor 4523 through a motor seat. The output shaft of the second motor 4523 is fixedly connected to the upper driving gear 4521. The rotation of the second motor 4523 drives the uppermost driving gear 4521 to rotate. Under the action of the transmission shaft 4522, the upper and lower driving gears 4521 rotate synchronously in the same direction, which can drive the installation gear ring 454 to rotate at a uniform speed within a certain angle. After a period of time, the second motor 4523 reverses to make the installation gear ring 454 rotate in the opposite direction. The positive and negative rotations are performed alternately. The angle of each rotation is the same but the speed is different. The positive rotation speed is much faster than the reverse rotation speed.

[0047] See also Figure 5 , Figure 6 and Figure 8 The magnetic attraction component 457 includes a cylindrical slider 4571, a magnetic attraction block 4572 and a matching slider 4573. The cylindrical slider 4571 is slidably arranged in the longitudinal guide groove 456. The end of the cylindrical slider 4571 close to the insulation cylinder 441 is fixedly connected with the magnetic attraction block 4572. The end of the magnetic attraction block 4572 close to the smelting furnace 44 is fixedly installed with the matching slider 4573, and the matching slider 4573 is connected to the corresponding arc guide groove 446 in a sliding manner; the reverse rotating installation gear ring 454 drives the connecting column 455 to move synchronously. Since the cylindrical slider 4571 is in the longitudinal guide groove 456 and the matching slider 4573 is in the arc guide groove 446, the magnetic attraction block 4572 finally makes a circumferential upward movement on the outer wall of the insulation cylinder 441; when the installation gear ring 454 rotates forward, the magnetic attraction block 4572 will return to the starting position.

[0048] In addition, the present invention also provides a waste steel processing and recycling process, comprising the following steps:

[0049] S1. Collection and sorting: sorting of scrap steel recovered from various fields.

[0050] S2. Cleaning and impurity removal: Clean the sorted scrap steel to remove impurities and pollutants.

[0051] S3, scrap smelting: the cleaned scrap steel is put into the crushing unit 2 for crushing, and the scrap is put into the smelting unit 4 by the conveying unit 3 to obtain molten steel liquid through smelting.

[0052] S4. Finished product processing: After further treatment and processing, the molten steel can be made into various steel products, such as steel plates and rebars.

[0053] The working principle of the present invention is as follows: the cleaned scrap iron and steel is crushed by the crushing unit 2, and the obtained crushed materials are conveyed by the conveying unit 3. When conveyed to the rightmost end, intermittent unloading is carried out. The crushed materials falling into the inner lining layer 444 from the feeding funnel 442 are continuously heated by the heating layer 443 until they are melted, and the two mounting gear rings 454 are driven by the driving component 452 to rotate synchronously in the same direction (forward and reverse rotation are performed alternately, with a fast forward rotation speed and a slow reverse rotation speed), and then the mounting gear ring 454 drives the connecting column 455 to rotate synchronously; during the process of the mounting gear ring 454 reversing at a uniform speed, the magnetic suction component 457 moves upward along the longitudinal guide groove 456 under the drive of the support column, and slides along the arc guide groove 446 at the same time, so that the magnetic suction component 457 performs a uniform upward motion on the outer wall of the heat-insulating cylinder 441. Due to the magnetic attraction of the magnetic suction component 457 The action can make the crushed materials in the lining layer 444 move toward the wall where the magnetic suction component 457 is located. The closer the crushed materials are to the heating layer 443, the faster they melt. During the movement, the crushed materials can drive the molten steel liquid to flow, further promoting the melting of the crushed materials. As the level of the molten steel liquid gradually rises, the magnetic suction component 457 rises slowly accordingly, and is used to guide the crushed materials that intermittently fall into the upper layer, thereby promoting melting. After completing the smelting treatment of a batch of scrap steel, the gear ring 454 is installed to rotate forward so that the magnetic suction component 457 returns to the starting point from top to bottom along the arc guide groove 446, and then the bottom slider 41 is controlled to move to the right. After it moves to the specified position and stops, the connecting shaft 43 is driven to rotate by the motor 1 46, so that the smelting furnace 44 as a whole rotates clockwise by a certain angle, so that the molten steel liquid in the smelting furnace 44 can be poured out from the discharge barrel 445.
