Abstract
Description
Technical Field
[0001] This utility model belongs to the field of mechanical technology and relates to a steel slag grinding device for asphalt concrete production. Background Technology
[0002] Asphalt concrete is a common building material widely used in road paving and construction projects. Steel slag, on the other hand, is an industrial waste product, a byproduct of steel production. To achieve resource recycling and effectively utilize steel slag in asphalt concrete, it can be ground into powder. This processed steel slag powder can then be added as an admixture to asphalt concrete, thus improving its performance and reducing environmental pollution.
[0003] In order to facilitate the addition of steel slag to the steel slag grinding device, and at the same time remove large pieces of steel slag that do not meet the requirements during the addition process, it is necessary to design a steel slag grinding device for asphalt concrete production. Summary of the Invention
[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a steel slag grinding device for asphalt concrete production.
[0005] The objective of this utility model can be achieved through the following technical solution: A steel slag grinding device for asphalt concrete production includes a main frame, on which a grinding mill body is fixed. The grinding mill body has an inlet on one side and an outlet on the other side. The device is characterized in that a secondary frame is arranged on the side of the main frame, and an outlet hopper is installed at the upper end of the secondary frame. The outlet hopper is connected to the inlet via a telescopic pipe. A storage box is installed at the lower end of the secondary frame. The storage box has a vertically continuous structure. A conveyor belt is installed on the secondary frame to lift the steel slag from the storage box to the outlet hopper. A vibrating screen plate is connected to the upper end of the storage box via multiple springs. Fixed baffles are fixedly connected to the front and rear sides of the vibrating screen plate. A vibrating motor is also fixedly installed at the bottom of the vibrating screen plate. Movable baffles are vertically slidably connected to the left and right sides of the storage box. The movable baffles are moved up and down by a push rod motor.
[0006] The push rod motor is fixed to the side of the storage box by a mounting block, and the push rod of the push rod motor is vertically upward. The end of the push rod motor is fixedly connected to the lower end of the movable baffle.
[0007] The storage box is also equipped with a guide block on its side, and a guide rod is vertically slidably connected to the guide block. The upper end of the guide rod is fixedly connected to the lower end of the movable baffle.
[0008] An elastic limiting block is also fixedly connected to the lower end of the guide rod.
[0009] An auxiliary cover is also provided between the storage box and the discharge hopper.
[0010] Compared with existing technologies, this steel slag grinding device for asphalt concrete production has the following advantages:
[0011] In this invention, a movable baffle is raised, and steel slag is manually placed onto the vibrating screen plate. Steel slag that meets the required size passes through the vibrating screen plate and enters the storage box. The movable baffle is lowered, and steel slag that does not meet the required size and remains on the vibrating screen plate falls to the ground from the side. At the same time, the steel slag in the storage box is lifted to the discharge hopper by a conveyor belt and enters the grinding mill body from the inlet through the telescopic pipe. The steel slag powder is output from the outlet, thus facilitating the grinding operation of steel slag. Attached Figure Description

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0017] like Figures 1-3As shown, this steel slag grinding device for asphalt concrete production includes a main frame 1, on which a grinding mill body 2 is fixed. The grinding mill body 2 has an inlet 201 on one side and an outlet 202 on the other side. The grinding mill body 2 adopts an existing structure. After the steel slag enters through the inlet 201, the steel slag powder is discharged through the outlet 202. A secondary frame 18 is arranged on the side of the main frame 1. An outlet hopper 4 is installed on the upper end of the secondary frame 18. The outlet hopper 4 is connected to the inlet 201 through a telescopic pipe 3. A storage box 14 is installed on the lower end of the secondary frame 18. The storage box 14 has a vertically continuous structure. The auxiliary frame 18 is equipped with a conveyor belt 15 for lifting steel slag from the storage box 14 to the discharge bucket 4. The conveyor belt 15 is an existing product. The upper end of the storage box 14 is connected to a vibrating screen plate 8 by multiple springs 9. Fixed baffles 7 are fixedly connected to the front and rear sides of the vibrating screen plate 8. A vibrating motor 6 is also fixedly installed at the bottom of the vibrating screen plate 8. Movable baffles 10 are vertically slidably connected to the left and right sides of the storage box 14. The movable baffles 10 are raised and lowered by a push rod motor 13. After the movable baffles 10 are raised, they can form a relatively closed screening area with the fixed baffles 7.
[0018] The push rod motor 13 is fixed to the side of the storage box 14 by the mounting block 16, and the push rod of the push rod motor 13 is vertically upward. The end of the push rod of the push rod motor 13 is fixedly connected to the lower end of the movable baffle 10. Specifically, a guide block 11 is also installed on the side of the storage box 14. A guide rod 12 is vertically slidably connected to the guide block 11. The upper end of the guide rod 12 is fixedly connected to the lower end of the movable baffle 10. An elastic limiting block 17 is also fixedly connected to the lower end of the guide rod 12. By using the guide block 11 and the guide rod 12 in cooperation, the movable baffle 10 can be stably raised and lowered.
[0019] An auxiliary cover 5 is also provided between the storage box 14 and the discharge hopper 4.
[0020] In this utility model, when the movable baffle 10 is raised, steel slag is manually placed onto the vibrating screen plate 8. Steel slag that meets the required size passes through the vibrating screen plate 8 and enters the storage box 14. When the movable baffle 10 is lowered, steel slag that does not meet the required size and remains on the vibrating screen plate 8 falls to the ground from the side. At the same time, the steel slag in the storage box 14 is lifted to the discharge hopper 4 by the conveyor belt 15 and enters the grinding mill body 2 from the inlet 201 along the telescopic pipe 3. The steel slag powder is output from the outlet 202, thus facilitating the grinding operation of steel slag.
[0021] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0022] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
