[0002] In the entire steel industry, about 30% to 40% of resources come from the recycling of scrap steel. Doing a good job in recycling scrap steel can reduce environmental pollution and improve social and economic benefits. The production process of hot-pressed steel blocks of slag particle steel includes raw material preparation, mixing, heating and melting, hot pressing and cooling.

[0003] The prior art still has the following deficiencies when heating slag particle steel: 1. When heating slag, multiple drivers are often required to cooperate with each other for loading, unloading and heating. A large number of driving devices are used, which significantly increases production costs; 2. When the slag is heated, the heat energy in it is easy to dissipate, resulting in energy consumption, and when the heated and molten slag is discharged, the slag splashes, which is easy to cause harm to the workers; In view of the above problems, the present invention document proposes a production device for hot-pressed steel blocks of slag particle steel and a method for using the same.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Example

[0023] Reference Figure 1-Figure 3 , production equipment, which is used in the field of slag steel processing equipment, mainly includes a bottom plate 1, the top of the bottom plate 1 is designed with a sliding connection structure, so that the moving platform 3 and the moving frame 5 can slide freely on it. Above the bottom plate 1, a rotary furnace body 2 is provided, and the rotary furnace body 2 is cleverly placed between the moving platform 3 and the moving frame 5 for subsequent operations.

[0024] Reference Figure 2 and Figure 8 A first through hole 15 and a second through hole 16 are respectively provided at both ends of the rotary furnace body 2. A burner 4 is fixed on one side of the movable platform 3. The burner 4 can pass through the first through hole 15 and extend into the interior of the rotary furnace body 2. Its function is to heat the raw materials in the rotary furnace body 2.

[0025] Reference Figure 2 , Figure 5 and Figure 8 A preheating bucket 6 is fixed on the top of the movable frame 5, and a chimney 24 is connected to the bottom of the preheating bucket 6. One end of the chimney 24 can be closely matched with the second through hole 16, so that the hot air in the rotary furnace body 2 is discharged into the preheating bucket 6 to achieve preheating of the raw materials. A first discharge pipe 26 is also provided on one side of the preheating bucket 6, and the first discharge pipe 26 can also be matched with the second through hole 16 to inject raw materials into the rotary furnace body 2. A valve is also provided on the first discharge pipe 26 to control the injection amount of the raw materials.

[0026] Reference Figure 2 and Figure 8 In order to transport the heated raw materials to the next process, the equipment is also provided with a feed pipe 32 on the top of the bottom plate 1. The feed pipe 32 is fixed on the bottom plate 1 by supporting legs to ensure its stability.

[0027] Reference Figure 1-Figure 7In order to drive the mobile platform 3, the mobile frame 5 and the rotary furnace body 2 to move and rotate, a driving structure is set on the top of the bottom plate 1. This driving structure includes two mounting seats 8 fixed on the top of the bottom plate 1, and the mounting seat 8 is located between the mobile platform 3 and the mobile frame 5. In the two mounting seats 8, there is a rotating shaft 9 that rotates and penetrates, and the outer wall of the rotating shaft 9 is fixed with a first gear 10. On the side of the mobile platform 3 close to the mounting seat 8, two first racks 11 are fixed through a connecting plate, and the two first racks 11 are respectively engaged with the two first gears 10. At the same time, a cross plate 28 is fixed on the side of the mobile frame 5 close to the mounting seat 8, and two second racks 27 are fixed on one side of the cross plate 28, and the two second racks 27 are also respectively engaged with the two first gears 10. Through such a design, when the rotating shaft 9 rotates, the first gear 10 can drive the first rack 11 and the second rack 27 to drive the mobile platform 3 and the mobile frame 5 to move toward or away from each other. A connecting arm 13 is fixed to the end of the two rotating shafts 9 close to each other, and the two connecting arms 13 are jointly fixed to a placement plate 12, and the rotary furnace body 2 is located above the placement plate 12. Therefore, when the rotating shaft 9 rotates, the rotary furnace body 2 can also be controlled to rotate. In order to drive this driving structure, a cylinder 7 is fixed on the top of the bottom plate 1, and the output shaft of the cylinder 7 is fixedly connected to one side of the moving platform 3, which is used to drive the moving platform 3 to move. In addition, a collection box 29 is also provided on the top of the bottom plate 1 to collect the residue in the rotary furnace body 2.

[0028] Specifically, during the working process, first, the output shaft of the cylinder 7 pulls the moving platform 3 in the direction away from the rotary furnace body 2, and the moving platform 3 simultaneously drives the first L-shaped support plate 34 to move, and the first L-shaped support plate 34 moves out from under the placement plate 12, releasing the support for the placement plate 12. At this time, the first rack 11 begins to mesh with the first gear 10, and the first gear 10 and the second rack 27 cooperate to drive the rotary furnace body 2 to rotate counterclockwise. When the rotary furnace body 2 rotates a certain angle, the first discharge pipe 26 on one side of the preheating bucket 6 is just aligned with the second through hole 16. At this time, the hollow metal plate 22 can be driven to vibrate by the vibration motor 23, and the steel slag on the hollow metal plate 22 can be discharged into the rotary furnace body 2 through the first discharge pipe 26.

[0029] Reference Figure 6 and Figure 7In order to drive the rotary furnace body 2 to rotate so that the raw materials inside can be heated evenly, the device sets a rotating structure on the outer wall of the rotary furnace body 2. This rotating structure includes two gear rings 17 fixed to the outer wall of the rotary furnace body 2, and two rotating rods 18 arranged under the rotary furnace body 2. The two rotating rods 18 are connected by a synchronous wheel and a synchronous belt to ensure that they can rotate synchronously. Two second gears 19 are fixedly sleeved on the outer wall of the rotating rod 18, and the two second gears 19 can mesh with the gear ring 17 to drive the rotary furnace body 2 to rotate. In order to provide driving force for the rotating rod 18, the device also fixes a driving motor 21 under the rotary furnace body 2, and the output shaft of the driving motor 21 is fixedly connected to one end of one of the rotating rods 18.

[0030] Specifically, the cylinder 7 drives the moving platform 3 and the moving frame 5 to move toward the middle until the moving platform 3, the rotary furnace body 2 and the moving frame 5 are reset. At this time, the burner 4 is inserted into the rotary furnace body 2 through the first through hole 15 to heat and melt the raw materials in the rotary furnace body 2. During the heating process, the driving motor 21 drives the two rotating rods 18 to rotate through the synchronous wheel and the synchronous belt, and the rotating rods 18 drive the rotary furnace body 2 to rotate through the engagement of the second gear 19 with the gear ring 17, thereby realizing uniform heating of the raw materials in the rotary furnace body 2.

[0031] Reference Figure 1 , Figure 2 and Figure 8 After heating is completed, the heated raw materials in the rotary furnace body 2 can be safely discharged through the discharge structure. The discharge structure includes a second discharge pipe 30 fixedly installed at one end of the rotary furnace body 2 close to the movable platform 3. On the outer wall of this second discharge pipe 30, we specially set a valve to control the discharge of raw materials. In order to further optimize the discharge process of raw materials, we rotatably sleeve a guide pipe 31 on the outer wall of the second discharge pipe 30. This guide pipe 31 can cooperate with the feed pipe 32, and its design purpose is to ensure that when discharging raw materials, the raw materials can be safely and smoothly injected into the feed pipe 32.

[0032] Specifically, after the heating process is completed, we will rotate the second discharge pipe 30 to the lower position. Then, open the valve on the second discharge pipe 30, and at this time, the raw materials in the rotary furnace body 2 will be discharged through the second discharge pipe 30. During the discharge process, the raw materials will first enter the guide pipe 31, and then be safely injected into the delivery pipe 32 through the guide pipe 31. The delivery pipe 32 is responsible for transporting the raw materials to the next process for processing. The existence of the guide pipe 31 effectively avoids the splashing of raw materials during the discharge process, thereby ensuring the stability and safety of the production process.

[0033] When the raw materials are discharged, the cylinder 7 is activated to drive the movable platform 3 and the movable frame 5 to move to both sides at the same time. This moving process will continue until the rotary furnace body 2 is in a vertical state. At this time, the residue in the rotary furnace body 2 will be discharged through the first through hole 15 set on the movable platform 3, and finally fall into the collection box 29 below for collection.

[0034] Reference Figure 7 On the top of the placement plate 12, we fixedly installed a plurality of arc-shaped support plates 20. These arc-shaped support plates 20 are rotatably connected to the outer wall of the rotary furnace body 2, and play a role in supporting the rotary furnace body 2. At the same time, on the top of the two connecting arms 13, we fixedly installed a limiting arc plate 14. The top inner wall of this limiting arc plate 14 is also rotatably connected to the outer wall of the rotary furnace body 2. The limiting arc plate 14 cooperates with the arc-shaped support plates 20 to limit the rotary furnace body 2 together, ensuring its stability and safety during rotation.

[0035] Reference Figure 2 Inside the preheating bucket 6, we fixedly installed a hollow metal plate 22. The main function of this hollow metal plate 22 is to hold the raw materials. At the bottom of the hollow metal plate 22, we also fixedly installed a vibration motor 23. This vibration motor 23 can vibrate the raw materials through the hollow metal plate 22, thereby improving the preheating effect of the raw materials.

[0036] Reference Figure 5 In addition, a rotating ring 25 is rotatably connected to one end of the chimney 24. The rotating ring 25 is matched with one end of the rotary furnace body 2 close to the moving frame 5. When the rotary furnace body 2 rotates, the rotating ring 25 can effectively reduce the friction between the rotary furnace body 2 and the chimney 24, thereby ensuring the smooth rotation of the rotary furnace body 2.

[0037] Reference Figure 1 , Figure 6 , Figure 7 and Figure 8 At one end of the rotary furnace body 2 close to the moving platform 3, a limit ring 33 is installed by welding or other fixing methods. The limit ring 33 is designed to ensure that the burner 4 can be effectively protected when extending into the rotary furnace body 2 for heating, so as to prevent the burner 4 from being damaged by high temperature or collision. At the same time, a PLC controller 37 is fixed on the top of the bottom plate 1. The PLC controller 37 serves as the control center of the entire device and is connected to the vibration motor 23, the drive motor 21, the burner 4 and the cylinder 7 respectively by electrical connection, so as to achieve precise control of these components.

[0038] Reference Figure 2 and Figure 3, two first L-shaped support plates 34 are installed on the side of the movable platform 3 close to the rotary furnace body 2 by bolts or other fixing methods, and the two first L-shaped support plates 34 are used to support one side of the bottom of the placement plate 12. At the same time, two second L-shaped support plates 35 are also fixed on the side of the movable frame 5 close to the rotary furnace body 2, and the two second L-shaped support plates 35 are used to support the other side of the bottom of the placement plate 12. Through the cooperation of the first L-shaped support plate 34 and the second L-shaped support plate 35, it can be ensured that the placement plate 12 and the rotary furnace body 2 thereon are in a horizontal and stable state. In addition, damping bearings 36 are fixed in the two mounting seats 8, and the ends of the two rotating shafts 9 that are away from each other extend into the two damping bearings 36 respectively. The design of the damping bearing 36 not only helps to reduce the friction and wear of the rotary furnace body 2 during the rotation process, but also further ensures the stability of the rotary furnace body 2.

[0039] Through the above specific implementation, we can clearly see how the production equipment realizes the production of hot pressed steel blocks of slag particle steel through the coordinated work of various components. The whole production process has a high degree of automation, simple and convenient operation, and greatly improves production efficiency. Example

[0040] refer to Fig. 9 , improved on the basis of Example 1: a filter box 38 is fixed on the side of the preheating bucket 6 away from the rotary furnace body 2, an exhaust pipe 39 is fixed on the top of the filter box 38, and one end of the exhaust pipe 39 extends into the preheating bucket 6 so as to guide the hot air in the preheating bucket 6 into the filter box 38. A filter cloth 40 is fixed in the filter box 38, and the function of the filter cloth 40 is to filter the dust in the hot air. At the same time, a plurality of exhaust holes 41 are provided at the bottom of the filter box 38 so as to discharge the filtered air. In addition, the chimney 24 is designed to be L-shaped, and a collecting cylinder 42 is detachably installed at its bottom.

[0041] Specifically, when the rotary furnace body 2 heats the raw materials, the hot air will enter the preheating bucket 6 to preheat the next batch of raw materials. At the same time, the vibration motor 23 vibrates the raw materials through the hollow metal plate 22 to make the raw materials looser and remove impurities therein. When the hot air in the preheating bucket 6 enters the filter box 38 through the exhaust pipe 39, the dust on the surface of the raw materials will be entrained into the filter box 38 and filtered through the filter cloth 40. When the hollow metal plate 22 vibrates, the dust and impurities on the surface of the raw materials will fall into the collection tube 42. Later, you only need to take out and empty the collection tube 42 to complete the dust removal work, thereby ensuring that the raw materials entering the rotary furnace body 2 later are relatively clean.

[0042] The method for using the production equipment of hot-pressed steel blocks made of slag particle steel comprises the following steps: S1. During loading, the output shaft of the cylinder 7 pulls the movable platform 3 away from the rotary furnace body 2, and the movable platform 3 synchronously drives the first L-shaped support plate 34 to move, and the first L-shaped support plate 34 moves out from under the placement plate 12, releasing the support for the placement plate 12, and the first rack 11 begins to mesh with the first gear 10. The first rack 11 drives the rotary furnace body 2 to rotate counterclockwise through the cooperation of the first gear 10 and the second rack 27, and the second rack 27 drives the movable frame 5 to move away from the rotary furnace body 2 until the rotary furnace body 2 rotates a certain angle, and the first discharge pipe 26 on one side of the preheating bucket 6 is just aligned with the second through hole 16, and the hollow metal plate 22 is driven to vibrate through the vibration motor 23, and the steel slag on the hollow metal plate 22 is discharged into the rotary furnace body 2 through the first discharge pipe 26; S2. During heating, the cylinder 7 drives the movable table 3 and the movable frame 5 to move toward the middle until the movable table 3, the rotary furnace body 2 and the movable frame 5 are reset. At this time, the first L-shaped support plate 34 and the second L-shaped support plate 35 support the placement plate 12, and the burner 4 is inserted into the rotary furnace body 2 through the first through hole 15 to heat and melt the raw materials in the rotary furnace body 2. During the heating process, the driving motor 21 drives the two rotating rods 18 to rotate through the synchronous wheel and the synchronous belt. The rotating rod 18 drives the rotary furnace body 2 to rotate through the meshing of the second gear 19 and the gear ring 17, so that the raw materials of the rotary furnace body 2 can be evenly heated. S3. During the heating process, the hot air in the rotary furnace body 2 enters the preheating bucket 6 through the cooperation of the second through hole 16 and the chimney 24 to preheat the raw materials to avoid heat energy waste. When the heating is completed, the second discharge pipe 30 rotates to the bottom, and the valve on the second discharge pipe 30 is opened. The raw materials in the rotary furnace body 2 can be discharged into the conveying pipe 32 through the second discharge pipe 30. The conveying pipe 32 conveys the raw materials to the next process, and the guide pipe 31 can avoid splashing when the raw materials are discharged. When the raw materials are discharged, the cylinder 7 drives the moving table 3 and the moving frame 5 to move to both sides until the rotary furnace body 2 is in a vertical state. At this time, the residue in the rotary furnace body 2 is discharged into the collection box 29 through the first through hole 15 for collection; S4. In addition, when the raw materials in the rotary furnace body 2 are heated, the hot air enters the preheating bucket 6 to preheat the next batch of raw materials. At the same time, the vibration motor 23 vibrates the raw materials through the hollow metal plate 22. When the hot air in the preheating bucket 6 enters the filter box 38 through the exhaust pipe 39, the dust on the surface of the raw materials can be entrained into the filter box 38, and the dust is filtered by the filter cloth 40. When the hollow metal plate 22 vibrates, the dust on the surface of the raw materials falls into the collecting tube 42. The collecting tube 42 is taken out later to complete the dust removal, thereby ensuring that the raw materials entering the rotary furnace body 2 later are relatively clean.
