Abstract
Description
Technical Field
[0001] This invention relates to the field of asphalt mixing and processing technology, and in particular to an energy-saving and environmentally friendly steel slag asphalt mixture pretreatment screening and processing equipment. Background Technology
[0002] Steel slag asphalt mixture is a solid waste recycling technology that uses steel slag, a byproduct of steelmaking, as aggregate to replace natural sand and gravel for road paving. This technology not only reduces project costs and increases the added value of steel slag, but also effectively improves the road performance of asphalt concrete, such as its high-temperature deformation resistance, water damage resistance, wear resistance, and skid resistance.
[0003] In the preparation of steel slag asphalt mixture, the steel slag needs to be screened in advance to select the appropriate material according to the mixture preparation requirements. Generally, the steel slag material is screened through a screening cylinder, which is inclined and has rotating rings on the outer walls of both ends of the cylinder that work with the drive wheels. The steel slag material enters from the top opening of the screening cylinder, which rotates to screen the material. The fine material falls from the side screen of the cylinder and is then conveyed; the coarse material falls from the bottom opening of the screening cylinder and is also conveyed.
[0004] During the mixing process, damp steel slag may adhere to the screen of the screening cylinder during screening, which not only affects the screening effect but also causes screen blockage, negatively impacting the mixing work. On the other hand, the screening cylinder lacks a mechanism to clean the material adhering to the screen to meet processing requirements.
[0005] Therefore, this invention proposes an energy-saving and environmentally friendly steel slag asphalt mixture pretreatment screening and processing equipment to solve the above problems. Summary of the Invention

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below. All other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present invention.
[0021] Example 1: Please refer to Figures 1-10 An energy-saving and environmentally friendly steel slag asphalt mixture pretreatment screening and processing equipment includes a screening cylinder body 1 and rotating rings 4 arranged on the outer sides of both ends of the screening cylinder body 1. The screening cylinder body 1 is arranged through the bearing rolling ring 2, and support legs 3 are symmetrically fixed on both sides of the bearing rolling ring 2. A baffle strip 11 is provided at equal intervals in a ring on the inner side wall of the screening cylinder body 1, and an auxiliary cone 12 is provided at equal intervals on the baffle strip 11. The auxiliary cone 12 and the baffle strip 11 work together to provide a material pushing effect in the screening cylinder body 1. A fixing body 5 is fixedly provided at the top of the outer side wall of the bearing rolling ring 2 near the bottom opening of the screening cylinder body 1. The fixing body 5 is fixedly connected to one end of the support rod 7, and the other end of the support rod 7 is provided with a loading clamp 8. The loading clamp 8 is connected to the drying mechanism, which provides a drying effect for the material in the screening cylinder body 1 and a cleaning effect for the material adhering to the screening cylinder body 1.
[0022] According to the appendix Figures 1-5 As shown, in the process of processing steel slag asphalt mixture, the steel slag material is screened. In addition to screening the steel slag material through the main body 1 of the screening cylinder, the air spray pipe 901 and the air spray head 903 are used in combination to provide a drying effect for the material in the main body 1 of the screening cylinder. On the one hand, this meets the drying requirements, and on the other hand, it prevents the accumulation and clogging of wet material on the screen of the screening cylinder during the screening process.
[0023] Furthermore, this solution also includes an auxiliary component at the top of the air duct 901. This auxiliary component works in conjunction with the connecting accessories to provide a material cleaning effect for the screen on the screening cylinder, which helps to prevent the material from clogging the screen. This is mainly achieved through the cooperation of the elastic tube 1107 and the cleaning cone 1110.
[0024] During the screening process, the material is screened by the rotation of the screening cylinder body 1. The baffle strip 11 and the auxiliary cone 12 located inside the screening cylinder body 1 work together to provide a material-pushing effect, which plays a positive role in the screening process. At the same time, the drying air conveyed from the drying air conveying pipe 902 enters the air spray pipe 901 and is then sprayed out from the air spray head 903 at the bottom of the air spray pipe 901 to provide a drying effect on the material in the screening cylinder body 1. The drying mechanism includes the air spray pipe 901, which is positioned by the loading clamp 8, and one end of the air spray pipe 901 is provided with the drying air conveying pipe 902. The air spray pipe 901 is located in the inner cavity of the screening cylinder body 1, and the air spray heads 903 are equidistantly arranged at the bottom of the air spray pipe 901. The axes of the air spray pipe 901 and the screening cylinder body 1 are coincident.
[0025] The material entering the screening cylinder body 1 will be located at the bottom of the inner cavity of the screening cylinder body 1. That is, as the screening cylinder body 1 rotates and is screened, the material will also flow along the screening cylinder body 1 until the screening work is completed.
[0026] Combined with the appendix Figure 3 and appendix Figures 6-9As shown, while the screening cylinder body 1 is screening the material, to prevent the material adhering to the screen from accumulating over a long period of time or even causing blockage, this solution uses a connecting accessory. This connecting accessory includes a support tube 1101; one end of the support tube 1101 is open, and the other end is sealed. A fixing ring 1102 is fixedly installed on the outer wall of the open end of the support tube 1101, and an auxiliary slot 1103 is provided on the inner side of the open end of the support tube 1101. This auxiliary slot 1103 is adapted to engage with the auxiliary retaining ring 1005 at the top of the air outlet 1004 to secure the support tube 1101. The installation of 1 provides a pre-positioning; wherein the fixing ring 1102 is connected to the sealing plate 1003 by screws; the sealing end of the support tube 1101 is provided with an installation port 1104 at equal intervals, and a retaining ring 1105 is provided in the installation port 1104; and the installation port 1104 is adapted to be inserted into the insertion ring 1106 at the bottom end of the elastic tube 1107; a side ring 1108 is also fixedly provided on the side of the bottom end of the elastic tube 1107, and the side ring 1108 is fixed to the support tube 1101 by screws; a screw groove 1109 is provided at the top end of the elastic tube 1107, and a cleaning cone 1110 is also provided at the top of the elastic tube 1107.
[0027] That is, when the screening cylinder body 1 rotates to screen the material, the cleaning cone 1110 will contact the screen on the screening cylinder body 1 to clean the material adhering to the screen. The cone tip of the cleaning cone 1110 can also extend into the mesh of the screen, which has an auxiliary effect on cleaning the material stuck in the mesh.
[0028] Then from the appendix Figure 6 and attached Figure 8 As shown, the cleaning cone 1110 is threadedly connected to the threaded groove 1109 at the top of the elastic tube 1107 via the external threaded connecting ring 1111 at the bottom, enabling individual disassembly and facilitating subsequent disassembly and maintenance. Furthermore, the connection between the cleaning cone 1110 and the elastic tube 1107 provides a flexible contact between the cleaning cone 1110 and the screen. In particular, as the screening cylinder body 1 rotates, the baffle strip 11 located inside the screening cylinder body 1 will also contact the cleaning cone 1110. To avoid rigid contact between the cleaning cone 1110 and the baffle strip 11, this prevents damage to the cleaning cone 1110 and avoids obstructing the rotation of the screening cylinder body 1.
[0029] Combined with the appendix Figure 10As shown, in order to further improve the cleaning effect of the screen on the main body 1 of the screening cylinder and provide a drying effect for the screen, this solution also provides an inner cavity in the cleaning cone 1110, which is also cone-shaped; an external threaded connecting ring 1111 is fixedly provided at the bottom end of the cleaning cone 1110, which is threadedly connected to the threaded groove 1109 at the top of the elastic tube 1107 to provide an installation function for the cleaning cone 1110; an air outlet 1112 is also provided on the cone surface of the cleaning cone 1110, which is connected to the inner cavity in the cleaning cone 1110, and the air outlet 1112 is used to spray out the drying air.
[0030] In other words, while cleaning the screen by scraping the material with the cleaning cone 1110, it also has a spray effect to assist in cleaning the material and to dry the screen.
[0031] In this solution, during material screening, the material accumulates at the bottom of the inner side of the screening cylinder body 1. The rotation of the screening cylinder body 1 then performs the screening action. Compared to existing technologies that rely solely on the screening cylinder for screening, this solution utilizes the combined use of the drying air conveying pipe 902 and the air spray head 903 to dry the moisture in the material, preventing excess moisture from clogging the mesh on the screening cylinder. Furthermore, this solution also employs a cleaning cone 1110 to remove adhesive residues. The cleaning cone 1110 provides a cleaning function for impurities attached to the main body of the screening cylinder 1, and also provides a material-discharging effect for materials adhering to the mesh of the screen body 1. This not only reduces the problem of material clogging the main body of the screening cylinder 1, but also avoids the waste of some materials that cannot be screened and recovered. Furthermore, by setting the first air guide head 1201 and the second air guide head 1202 on the cleaning cone 1110, it provides an auxiliary function for the material discharging work of the cleaning cone 1110, and also provides a drying effect for the screen on the main body of the screening cylinder 1.
[0032] The auxiliary components of the drying mechanism include air guide pipes 1001 equidistantly positioned at the top of the air spray pipe 901. The top of the air guide pipe 1001 is connected to the loading box 1002, which is sealed by a sealing plate 1003 and fixed with screws. Air outlets 1004 are equidistantly positioned on the sealing plate 1003, and auxiliary retaining rings 1005 are fixedly installed at the top of the air outlets 1004. The drying air entering the air spray pipe 901 is sprayed downwards through the air nozzle 903, and also enters the support pipe 1101 from the air guide pipe 1001 at the top of the air spray pipe 901, then enters the elastic pipe 1107, and finally is sprayed out from the air outlet 1112 on the side wall of the cleaning cone 1110. This effectively removes the material adhering to the screen and has a positive effect on cleaning the material.
[0033] Both the support tube 1101 and the flexible tube 1107 can be disassembled separately for easy replacement and maintenance. The auxiliary slot 1103 at the bottom of the support tube 1101 is inserted into the auxiliary retaining ring 1005 at the top of the air outlet 1004 on the sealing plate 1003, and then fixed by the fixing ring 1102 to secure the support tube 1101. For the installation of the flexible tube 1107, the insertion ring 1106 at the bottom of the flexible tube 1107 is inserted into the mounting port 1104 at the top of the support tube 1101, and then the side ring 1108 at the bottom of the flexible tube 1107 is fixed with screws. This design allows for the replacement of one or more parts of the support tube 1101, the flexible tube 1107, and the cleaning cone 1110 during future maintenance, providing greater operational flexibility.
[0034] Furthermore, since the sealing plate 1003 and the loading box 1002 are fixedly connected by screws, after disassembling the sealing plate 1003, all the supporting tubes 1101 connected to the sealing plate 1003 can be removed.
[0035] From the appendix Figure 10As can be seen from the diagram, this solution also includes a first air guide head 1201 fixedly installed at the outer opening of the air outlet body 1112 on the side wall of the cleaning cone 1110. This first air guide head 1201 is inclined towards the tip of the cleaning cone 1110. A second air guide head 1202 is also installed on one side of the first air guide head 1201, and the second air guide head 1202 is connected to the first air guide head 1201, with the second air guide head 1202 facing towards the cleaning cone 1110. The bottom of the 0 is tilted; a filter strip 1203 is also provided in the first air guide head 1201, and the filter strip 1203 is located near the connection port between the first air guide head 1201 and the second air guide head 1202. The filter strip 1203 is used to provide a filtering and blocking effect on the material; that is, when the drying air is sprayed outward through the air outlet body 1112, the first air guide head 1201 can better guide the drying air to the screen, and can better concentrate the air force to blow away the material.
[0036] Furthermore, this solution also includes a second air guide head 1202 on one side of the first air guide head 1201 and a filter strip 1203 in the first air guide head 1201. While the first air guide head 1201 is blowing air towards the screen, material may enter the first air guide head 1201. The filter strip 1203 can then block the material, preventing it from entering the cleaning cone 1110, and then filtering it out from the attached... Figure 10 It can be seen that the filter bar 1203 is also inclined, that is, the filter bar 1203 forms an angle with the axis of the first air guide head 1201, and the filter bar 1203 is inclined toward the position of the second air guide head 1202. In other words, the material blocked by the filter bar 1203 can be discharged from the second air guide head 1202 to avoid clogging the filter bar 1203 and affecting its air spraying operation.
[0037] Another purpose of setting up the second air guide head 1202 is that the air sprayed from the second air guide head 1202 can also provide a blowing effect on the material adhering to the adjacent cleaning cone 1110, so as to ensure the normal use of the cleaning cone 1110; that is, the air sprayed from the second air guide head 1202 will provide a blowing effect on the cleaning cone 1110 next to it, and provide a cleaning effect on the impurities adhering to the adjacent cleaning cone 1110.
