Description

Technical Field

[0001] This utility model relates to the technical field of mixture processing equipment, and in particular to a processing equipment for steel slag asphalt mixture. Background Technology

[0002] As a byproduct of steelmaking, steel slag has the characteristics of igneous rock, containing a variety of oxides and minerals. It has a similar physicochemical composition to silicates. The surface of steel slag is rough and porous, which can form good adhesion with asphalt, improve the thermal and water stability of the mixture. In addition, steel slag has high wear resistance and strength, which can significantly improve the service life of asphalt pavement.

[0003] A search revealed that patent CN111827047A discloses a steel slag asphalt mixture and its mixing equipment. Although the mixing equipment achieves the tumbling and mixing of the mixture in the mixing tank, which facilitates the full mixing of the mixture, the asphalt fluidity decreases as the asphalt temperature drops during the mixing process, making it difficult to ensure that the asphalt is evenly coated on the surface of aggregates such as steel slag, thus which is not conducive to ensuring the uniformity of the mixture.

[0004] To address the aforementioned problems, this utility model document proposes a processing equipment for steel slag asphalt mixture. Utility Model Content

[0005] This invention provides a processing equipment for steel slag asphalt mixture, which solves the shortcomings of the prior art where the fluidity of asphalt decreases as the temperature of asphalt drops during the mixing process, making it difficult to ensure that the asphalt is evenly coated on the surface of aggregates such as steel slag, thus making it difficult to ensure the uniformity of the mixture.

[0006] This utility model provides the following technical solution:

[0007] A processing device for steel slag asphalt mixture, comprising:

[0008] The mixing chamber has support legs welded and fixed at the four corners of its bottom. A reinforcing plate is welded and fixed at the other end of each support leg. The reinforcing plate has two reserved holes for reinforcement with the ground. The mixing chamber is equipped with a stirring component to improve the mixing effect of the mixture.

[0009] The mixing chamber has a matching cover snapped into the top opening. The top of the cover is symmetrically connected to two covered feeding hoppers. The cover is equipped with a heating component for heating the mixture. The bottom opening of the mixing chamber is rotatably installed with a discharge baffle.

[0010] In one possible design, the stirring assembly includes two drive rods whose ends are rotatably mounted on both ends of the inner wall of the mixing chamber via bearings. Multiple sets of cross-shaped stirring blades are staggered and welded onto the two drive rods. One end of each drive rod passes through the outer wall of the mixing chamber and is fixedly mounted with a drive gear. The two drive gears mesh with each other.

[0011] In one possible design, a mounting frame is welded and fixed to the outer wall of the mixing chamber, and both of the transmission gears are located inside the mounting frame. A drive motor for driving one of the transmission gears to rotate is fixedly mounted on the outer wall of the mounting frame, and the output shaft of the drive motor passes through the inner wall of the mounting frame and is fixedly connected to the center of the outer wall of one of the transmission gears.

[0012] In one possible design, the heating assembly includes two flame burners symmetrically fixedly installed on the top of the compartment cover. The output end of the flame burner passes through the bottom of the compartment cover and extends into the mixing compartment. An oil supply tank is fixedly installed on the top of the compartment cover. The oil supply tank is connected to the oil supply ends of the two flame burners through oil supply pipes.

[0013] In one possible design, the output end of the flame burner is threaded with a filter cap to prevent steel slag from entering the pipe.

[0014] In one possible design, a hinged seat is fixedly provided along the lower edge of the outer wall of the mixing chamber, and a connecting rod is hinged to the hinged seat. The other end of the connecting rod is fixedly connected to the bottom of the discharge baffle.

[0015] In one possible design, fixing blocks are welded and fixed to one side of the discharge baffle and the outer wall of the bottom opening of the mixing bin. The same bolt is installed through the through holes of the two fixing blocks, and the bottom end of the bolt passes through the two through holes and is threaded with a matching nut.

[0016] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the present invention.

[0017] The working principle and usage process of this technical solution are as follows:

[0018] Before use, align the pre-drilled holes on the reinforcing plates of the bottom support legs of the mixing chamber with the ground. Secure the equipment to the ground using anchor bolts through the pre-drilled holes. Open the cover of the feeding hopper on the chamber cover and add raw materials such as steel slag and liquid asphalt into the mixing chamber through the feeding hopper, ensuring that the raw materials do not submerge the flame burner output end. Then, close the cover of the feeding hopper. After starting the drive motor, the drive motor will drive one of the transmission gears to rotate. Because the two transmission gears mesh with each other, this will cause the two transmission rods and the cross-shaped stirring blades above them to rotate, thus mixing the materials in the mixing chamber. Stirring improves the mixing effect. After the flame burner is turned on, the oil supply tank supplies oil to the flame burner through the oil pipe. The output end of the flame burner sprays flames into the mixing chamber to heat the mixture that is constantly rolling to the top, preventing the asphalt from solidifying and allowing the asphalt to better coat aggregates such as steel slag. The filter cap can prevent steel slag from entering the flame burner tube. When the mixture is evenly mixed and reaches the required state, use a tool to unscrew the matching nut on the bolt, remove the bolt, and rotate the discharge baffle around the hinge seat through the connecting rod to open the bottom opening of the mixing chamber for discharge.

[0019] This utility model has the following beneficial effects:

[0020] This invention utilizes cross-shaped mixing blades staggered on two transmission rods in the mixing assembly, which rotate under the drive of a motor to fully mix the mixture and effectively improve the mixing effect. The flame burner in the heating assembly heats the constantly churning mixture during the mixing process, giving the asphalt good fluidity and allowing it to better coat aggregates such as steel slag, thus ensuring the uniformity of the mixture.

[0021] In this utility model, the discharge baffle is connected to the mixing chamber through a hinged seat and a connecting rod, and is fixed with bolts and nuts. The operation is simple during discharge, and it is convenient to discharge the mixed material from the mixing chamber. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0030] Example 1

[0031] Please refer to Figure 1-4 A processing device, comprising:

[0032] Mixing chamber 1, with support legs 3 welded and fixed at the four corners of the bottom of mixing chamber 1, and a reinforcing plate 4 welded and fixed at the other end of the support legs 3. The reinforcing plate 4 has two reserved holes 5 for ground reinforcement. Align the reserved holes 5 on the reinforcing plate 4 on the support legs 3 at the bottom of mixing chamber 1 with the ground, and fix the equipment to the ground with anchor bolts through the reserved holes 5 to improve the stability of the equipment during operation.

[0033] A matching bin cover 2 is snapped onto the top opening of the mixing bin 1. Two feeding hoppers 6 are symmetrically connected to the top of the bin cover 2. The top of the feeding hoppers 6 is equipped with an openable cover plate. Open the cover of the feeding hoppers 6 on the bin cover 2 and add raw materials such as steel slag and liquid asphalt into the mixing bin 1 through the feeding hoppers 6. Note that the raw materials should not submerge the output end of the flame burner 12. Then close the cover of the feeding hoppers 6 to prevent the raw materials from splashing out during the mixing process.

[0034] The mixing chamber 1 is equipped with a stirring assembly to improve the mixing effect of the mixture. The stirring assembly includes two horizontally arranged transmission rods 7. The two ends of the transmission rods 7 are rotatably mounted on the inner wall of the mixing chamber 1 through bearing sets. Multiple sets of cross-shaped stirring blades 8 are welded equidistantly along the axial direction on the surface of each transmission rod 7. The cross-shaped stirring blades 8 on the two sets of transmission rods 7 are spatially staggered. The ends of the transmission rods 7 extend to the outside of the mixing chamber 1 and are fixedly mounted with transmission gears 9. The two transmission gears 9 mesh with each other to form a gear transmission pair. A U-shaped mounting bracket 10 is welded to the outer wall of the mixing chamber 1. The drive motor 11 is fixed to the outside of the mounting bracket 10 by bolts. The output shaft of the drive motor 11 passes through the side wall of the mounting bracket 10 and is keyed to the center hole of one of the transmission gears 9. After the drive motor 11 is started, the drive motor 11 drives one of the transmission gears 9 to rotate. Since the two transmission gears 9 mesh with each other, the two transmission rods 7 and the cross-shaped stirring blades 8 on them rotate, stirring the mixture in the mixing chamber 1 and improving the mixing effect.

[0035] The silo cover 2 is equipped with a heating component for heating the mixture. The heating component includes two flame burners 12, which are symmetrically fixed on the top of the silo cover 2. The output end of the flame burner 12 passes through the bottom of the silo cover 2 and extends into the mixing chamber 1. An oil supply tank 13 is fixedly installed on the top of the silo cover 2. The oil supply tank 13 is connected to the oil supply end of the two flame burners 12 through an oil supply pipe. An electromagnetic control valve is installed in the middle of the oil supply pipe. After the flame burner 12 is turned on, the oil supply tank 13 supplies oil to the flame burner 12 through the oil supply pipe. The fuel forms a rotating airflow in the vortex chamber inside the nozzle, which mixes with the combustion air provided by the burner's own fan to form a combustible mixture. The high-voltage electronic ignition device built into the burner generates an electric spark to ignite the flame at the moment the mixture is ejected, forming a high-temperature diffusion flame that is sprayed into the mixing chamber 1 to heat the mixture that is constantly rolling to the top, preventing the asphalt from solidifying and allowing the asphalt to better coat aggregates such as steel slag.

[0036] A rectangular discharge port is provided at the bottom of the mixing chamber 1. An openable discharge baffle 15 is installed at the discharge port via a rotating shaft. A hinge seat 16 is welded to the lower part of the outer wall of the mixing chamber 1. The hinge seat 16 forms a rotating pair with one end of the connecting rod 17 via a pin. The other end of the connecting rod 17 is welded and fixed to the bottom of the discharge baffle 15. When the discharge baffle 15 is closed, the fixing block 18 welded to its side is aligned with the fixing block 18 welded to the outer wall of the mixing chamber 1. Hexagonal bolts 19 are inserted into the through holes of the two fixing blocks 18. Nuts 20 are threaded to the ends of the bolts 19. When the mixture is stirred evenly and reaches the required state, the nuts 20 on the bolts 19 are unscrewed with tools, the bolts 19 are removed, and the discharge baffle 15 is rotated around the hinge seat 16 via the connecting rod 17 to open the bottom opening of the mixing chamber 1 for discharge.

[0037] This application can be used for the production of steel slag asphalt mixtures, or for other fields applicable to this application.
