Description

Technical Field

[0001] This application relates to the field of dry quenched coke transportation technology, and in particular to a dust suppression transportation trolley for dry quenched coke in coking plants. Background Technology

[0002] In the production process of a coking plant, dry quenching is a crucial step. As a product of coke cooling, dry quenching needs to be transported to subsequent processing stations or storage areas by special transport vehicles.

[0003] In existing technologies, the material distribution function of traditional dry quenching coke transport trolleys has significant limitations. The distribution direction and range are often fixed and cannot be flexibly adjusted according to the needs of different workstations.

A U-shaped material distribution plate 19 connected to the discharge port 16 is fixedly installed on the left outer wall of the transport vehicle 12. The bottom inner wall of the U-shaped material distribution plate 19 has an inclined surface structure. The electric telescopic rod 17 can control the vertical lifting and lowering of the sealing plate 18, thereby realizing the rapid opening and closing of the discharge port 16. In conjunction with the inclined inner wall at the bottom of the transport vehicle 12, the dry quenched coke in the transport vehicle 12 can be continuously and smoothly discharged from the discharge port 16 and enter the U-shaped material distribution plate 19.

Figure 3 and Figure 5 As shown, the electric telescopic rod 17 is in the extended state.

[0028] In this embodiment, the rotation adjustment component is used to control the horizontal rotation of the transport vehicle 12, thereby changing the orientation of the U-shaped fabric plate 19.

[0029] In this embodiment, the walking assembly is used to control the transport frame and transport box 12 to move forward or backward along the track 13. The walking assembly includes two motors 9, two gears 10, and two racks 11. The two motors 9 are fixedly installed at the bottom of the base plate 1 and symmetrically distributed on both sides of the track 13.

[0030] In this embodiment, a plurality of support rods 14 are fixedly installed at the bottom of the top plate 4. The plurality of support rods 14 are distributed in a ring with equal spacing around the bearing seat 2. The bottom ends of the plurality of support rods 14 are in sliding contact with the top of the bottom plate 1. The design of the plurality of support rods 14 serves to support the top plate 4, making the rotation of the top plate 4 more stable.

[0031] In this embodiment, rollers 15 are rotatably installed at the four corners of the bottom of the base plate 1 to improve the stability of the transport frame and transport box 12 when they move, and to ensure the smooth transport of dry quenched coke.

[0032] In this embodiment, a dust collection assembly is provided on the transport vehicle box 12. The dust collection assembly is used to extract dust around the transport vehicle box 12. The dust collection assembly includes a dust collection box 20, an air pump 21, a filter screen 22, two dust conveying pipes 23, two L-shaped plates 24, two suction pipes 25, and multiple suction heads 26. The dust collection box 20 is fixedly installed at the bottom of the transport vehicle box 12 and located on the right side of the support base 5. The air pump 21 is fixedly installed at the top of the top plate 4, and the suction end of the air pump 21 extends into the dust collection box 20. The filter screen 22 is fixedly installed inside the dust collection box 20. The two dust conveying pipes 23 are respectively fixedly installed on the left and right side walls of the dust collection box 20. One end of each of the two dust conveying pipes 23 extends into the dust collection box 20 and is located above the filter screen 22. The two L-shaped plates 24 are respectively fixedly installed on the left and right side walls of the dust collection box 20. The dust collection box 20, the two dust conveying pipes 23 and the two dust collection pipes 24 are fixedly installed on the front and rear sides of the top of the transport box 12. The other ends of the two dust conveying pipes 23 are fixedly connected to the corresponding dust collection pipes 25. Multiple dust collection heads 26 are fixedly installed on the two dust collection pipes 25 and are evenly distributed. The suction force generated by the air pump 21 during operation can draw out the air in the dust collection box 20, the two dust conveying pipes 23 and the two dust collection pipes 25, so that negative pressure is generated inside. Then, multiple dust collection heads 26 can efficiently suck up dust from around the transport box 12 and transport it to the dust collection box 20 through the dust conveying pipes 23, which greatly reduces the spread of dust and reduces the impact on the workshop environment and personnel health. The filter screen 22 can intercept and filter dust to prevent it from entering the air pump 21 with the airflow.

[0033] In this embodiment, a dust removal port located above the filter screen 22 is provided on the inner right side wall of the dust collection box 20, and a sealing cover plate 27 is fixedly installed on the outer right side wall of the dust collection box 20 by screws. The sealing cover plate 27 is adapted to the dust removal port. The design of the dust removal port and the sealing cover plate 27 facilitates the periodic cleaning of dust in the dust collection box 20.

[0034] In this embodiment, a battery pack 28 is fixedly installed on the top of the base plate 1. The first motor 6, the two second motors 9, the electric telescopic rod 17, and the air pump 21 are all electrically connected to the battery pack 28. The battery pack 28 is used to supply power to the first motor 6, the two second motors 9, the electric telescopic rod 17, and the air pump 21. A multi-control switch is installed on the side wall of the base plate 1. The multi-control switch is electrically connected to the first motor 6, the two second motors 9, the electric telescopic rod 17, the air pump 21, and the battery pack 28. The first motor 6 and the two second motors 9 are both reversible motors. The multi-control switch is used to control the power supply and operation of the first motor 6, the two second motors 9, the electric telescopic rod 17, and the air pump 21 respectively. The wiring connection method and control method are conventional technologies in this field, so they will not be described in detail here.

[0035] Based on the above structure, the working principle of the coking plant dry quenching coke cloth dust suppression and transportation trolley provided in this application is as follows:

[0036] A suitable amount of dry-quenched coke is loaded into the transport car body 12. By controlling the operation of two motors 9 with the same speed but opposite direction, two gears 10 can be made to rotate in opposite directions at the same time. By using the meshing transmission action of the two gears 10 and the corresponding racks 11, the transport frame and transport car body 12 can be controlled to move along the track 13, and the dry-quenched coke can be transported to the next designated processing station. After the dry-quenched coke is transported to the next designated station, the operation of the two motors 9 is stopped.

[0037] Then, control the electric telescopic rod 17 to retract and reset, driving the baffle plate 18 to rise and return to its original position, thereby removing the obstruction to the discharge port 16. The dry-quenched coke in the transport box 12 flows automatically to the discharge port 16 under the action of gravity along its inclined bottom inner wall, and is then evenly discharged through the inclined bottom inner wall of the U-shaped cloth plate 19. During the discharge process, by controlling the operation of the motor 6, the gear 7 can be driven to rotate. Utilizing the meshing transmission action of the gear 7 and the external gear ring 8, the column 3 can be controlled to rotate, so that the transport box 12 rotates horizontally around the column 3 as the center, thereby changing the orientation of the U-shaped cloth plate 19. This allows for flexible adjustment of the cloth direction and range, meeting the cloth needs of different areas and avoiding uneven accumulation of dry-quenched coke.

[0038] During the loading, transportation, and distribution of dry-quenched coke, the air pump 21 is turned on to extract air from the dust collection box 20, the two dust conveying pipes 23, and the two suction pipes 25, creating a negative pressure inside. This allows multiple suction heads 26 to efficiently and comprehensively extract dust from around the transport vehicle 12. The extracted dust is then transported to the dust collection box 20 via the dust conveying pipes 23. The filter screen 22 intercepts and filters the dust, preventing it from entering the air pump 21 with the airflow. This significantly reduces dust diffusion and minimizes the impact on the workshop environment and personnel health.
