Description

Technical Field

[0001] This utility model relates to the field of dust adsorption technology, and in particular to a dust adsorption mechanism for a scrapped vehicle dismantling workshop. Background Technology

[0002] Vehicle dismantling refers to the process of dismantling, sorting, and recycling cars that have reached the end of their service life. Through dismantling, valuable parts of old cars can be recycled and reused, saving resources and reducing environmental pollution. However, the waste generated after dismantling also needs to be treated to protect the environment and human health. Currently, vehicle dismantling is carried out in workshops; however, this process generates a large amount of dust, so conventional dismantling workshops are equipped with dust collection systems for dust removal.

[0003] However, when conventional dust adsorption mechanisms are installed in dismantling workshops, they cause severe corrosion of the filtration equipment. Metal dust mixed with oil mist in the dismantling workshop will form acidic condensates, which will shorten the life of the filter media. Because it contains oil mist, it will clog the filter screen and reduce the filtration efficiency. Therefore, we have proposed a dust adsorption mechanism for end-of-life vehicle dismantling workshops to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a dust adsorption mechanism for scrap car dismantling workshops.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dust adsorption mechanism for a scrap vehicle dismantling workshop includes a protective box, inside which is a conical spray box. A spiral spray mechanism is provided on the circumference of the conical spray box. A filter box is connected to the lower end of the conical spray box. A collection mechanism is provided on the circumference of the filter box. A spherical filter screen is provided inside the filter box. A rotating mechanism is installed on one side of the filter box and connected to the spherical filter screen. An output structure is connected to the lower end of the filter box.

[0007] Preferably, the spiral spraying mechanism includes a spiral spray pipe wound at equal intervals around the side wall of a conical spray box. Multiple spray holes are provided at equal intervals on the side wall of the spiral spray pipe, and the spray holes and the conical spray box are connected through each other. A spray tank is fixed to one side of the protective box. One end of the spiral spray pipe passes through the side wall of the protective box and is connected to one side of the spray tank. A delivery pump is installed inside the spray tank.

[0008] Preferably, the collection mechanism includes a collection box installed on the side wall of the filter box, two guide grooves are provided on the side wall of the filter box, and the two guide grooves and the collection box are connected through each other. A collection pipe is connected to one side of the lower end of the collection box, the lower end of the collection pipe penetrates the side wall of the protective box, and a storage tank is connected to one side of the collection pipe.

[0009] Preferably, the rotating mechanism includes a protective box fixed to one side of the lower end of the filter box, a rotating rod rotatably connected to the bottom of the protective box, the rotating rod passing through the protective box and the side wall of the filter box and connected to one end of the spherical filter screen, a servo motor fixed to one side of the bottom of the protective box, and gears fixedly mounted on the output shaft of the servo motor and the rotating rod, and the two gears meshing with each other.

[0010] Preferably, the output structure includes U-shaped guide pipes connected to both sides of the lower end of the filter box, one end of the U-shaped guide pipe is connected to an output pipe, and the output pipe passes through the side wall of the protective box and extends to the lower end of the protective box.

[0011] Preferably, the upper end of the conical spray box is connected to an input pipe, the upper end of which penetrates the side wall of the protective box and extends to the upper end of the protective box.

[0012] In this invention, a modular design is adopted. The overall device can be configured in one or more groups according to usage requirements. When a single group performs filtration and dust removal, it first performs primary atomization and capture. The dust-laden airflow enters the conical spray box through the input pipe and comes into counter-current contact with the atomized droplets generated by the spiral spray pipe. Coarse particles and oil mist condensates are captured. Then, it performs secondary dynamic filtration. The remaining particles enter the rotating spherical filter screen, where fine metal dust is trapped. The spherical filter screen generates centrifugal force under the drive of the rotating mechanism. The centrifugal force throws the spray droplets containing oil mist into the guide grooves on both sides for recycling. The gas is released through the output structure.

[0013] This utility model has the following advantages:

[0014] 1. Modular design allows the overall device to be configured in one or more groups according to actual usage needs. In scrap car dismantling workshops of different sizes, the number of devices can be flexibly selected based on factors such as workshop size and dust generation to achieve the best filtration and dust removal effect.

[0015] 2. Easy to maintain and replace. When a module fails, it can be repaired or replaced individually without affecting the normal operation of other modules, which greatly shortens the equipment maintenance time and reduces maintenance costs.

[0016] 3. Through primary atomization and capture, most coarse particles and oil mist condensates are removed, which purifies the airflow entering the subsequent filtration stage, helps protect the subsequent filtration equipment, extends its service life, and reduces the frequency of filter media replacement.

[0017] 4. The rotating spherical filter screen can not only effectively trap the remaining fine metal dust, but also throw the spray droplets containing oil mist into the guide channels on both sides for recycling. The recycled spray liquid can be treated and reused, reducing operating costs.

[0018] In summary, this invention effectively removes dust and oil mist generated during the dismantling of scrapped vehicles through primary atomization capture and secondary dynamic filtration, reducing pollution to the air in the workshop. At the same time, by first removing coarse particles and oil mist condensates and then filtering fine dust, the burden and corrosion of the filtration equipment are reduced, effectively extending the service life of the filtration equipment and lowering the replacement cost.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-5The dust adsorption mechanism in the scrap vehicle dismantling workshop includes a protective box 18, a conical spray box 2 inside the protective box 18, a spiral spray mechanism on the side wall of the conical spray box 2, a filter box 10 connected to the lower end of the conical spray box 2, a collection mechanism on the side wall of the filter box 10, a spherical filter screen 17 inside the filter box 10, a rotating mechanism installed on one side of the filter box 10, the rotating mechanism and the spherical filter screen 17 connected, and an output structure connected to the lower end of the filter box 10.

[0027] The spiral spray mechanism includes a spiral spray pipe 3 wound at equal intervals around the side wall of a conical spray box 2. Multiple spray holes 13 are provided at equal intervals on the side wall of the spiral spray pipe 3, and the spray holes 13 and the conical spray box 2 are connected. A spray tank 11 is fixed on one side of a protective box 18. One end of the spiral spray pipe 3 passes through the side wall of the protective box 18 and is connected to one side of the spray tank 11. A delivery pump is installed in the spray tank 11. When the delivery pump is started, the liquid in the spray tank 11 is delivered to the spiral spray pipe 3, and then sprayed into the conical spray box 2 in the form of atomized droplets through the spray holes 13. After the dust-laden airflow enters the conical spray box 2 from the input pipe 1, it comes into contact with these atomized droplets in the opposite direction. Coarse particles and oil mist condensates are captured by the atomized droplets, thereby achieving first-level dust treatment. The spiral spray design can make the atomized droplets more evenly distributed in the conical spray box 2, improving the efficiency of dust capture.

[0028] The collection mechanism includes a collection box 4 installed on the side wall of the filter box 10. Two guide channels 12 are provided on the side wall of the filter box 10, and the two guide channels 12 are connected to the collection box 4. A collection pipe 5 is connected to the lower end of the collection box 4, and the lower end of the collection pipe 5 penetrates the side wall of the protective box 8. A storage tank 6 is connected to one side of the collection pipe 5. During the secondary dynamic filtration process, the spherical filter screen 17 generates centrifugal force under the drive of the rotating mechanism, throwing the spray droplets containing oil mist into the guide channels 12 on both sides. These droplets flow into the collection box 4 along the guide channels 12, and then enter the storage tank 6 through the collection pipe 5 for storage. This allows for the recycling of the spray droplets, saving resources and reducing environmental pollution.

[0029] The rotating mechanism includes a protective box 8 fixed to one side of the lower end of the filter box 10. A rotating rod 15 is rotatably connected to the bottom of the protective box 8. The rotating rod 15 passes through the protective box 8 and the side wall of the filter box 10 and is connected to one end of the spherical filter screen 17. A servo motor 16 is fixed to one side of the bottom of the protective box 8. Gears 14 are fixedly mounted on the output shaft of the servo motor 16 and the rotating rod 15, and the two gears 14 mesh with each other. When the servo motor 16 is started, the gear 14 on its output shaft rotates. By meshing with the gear 14 on the rotating rod 15, the rotating rod 15 is driven to rotate, thereby causing the spherical filter screen 17 to rotate. The rotating spherical filter screen 17 can trap fine metal dust in the remaining particles. At the same time, the centrifugal force generated throws the spray droplets containing oil mist into the guide channel 12. By controlling the speed of the servo motor 16, the rotation speed of the spherical filter screen 17 can be adjusted to adapt to different dust treatment needs.

[0030] The output structure includes U-shaped guide pipes 9 connected to both sides of the lower end of the filter box 10. One end of the U-shaped guide pipe 9 is connected to the output pipe 7. The output pipe 7 penetrates the side wall of the protective box 18 and extends to the lower end of the protective box 18. After primary atomization and secondary dynamic filtration, the dust is effectively removed. The treated gas is discharged from the protective box 18 through the U-shaped guide pipe 9 and the output pipe 7. The design of the U-shaped guide pipe 9 can play a certain buffering role, making the gas discharge more stable.

[0031] The upper end of the cone-shaped spray box 2 is connected to the input pipe 1. The upper end of the input pipe 1 penetrates the side wall of the protective box 18 and extends to the upper end of the protective box 18. The dust-laden airflow enters the cone-shaped spray box 2 through the input pipe 1, and the entire dust treatment process begins.

[0032] In this utility model, a modular design is adopted. The overall device can be configured in one or more groups according to usage requirements. When a single group performs filtration and dust removal, it first performs primary atomization capture. The dust-laden airflow input pipe 1 enters the conical spray box 2 and comes into counter-current contact with the atomized droplets generated by the spiral spray pipe 3. Coarse particles and oil mist condensates are captured. Then, it performs secondary dynamic filtration. The remaining particles enter the rotating spherical filter screen 17, where fine metal dust is intercepted. The spherical filter screen 17 generates centrifugal force under the drive of the rotating mechanism. The centrifugal force throws the spray droplets containing oil mist into the guide grooves 12 on both sides for recycling. The gas is released through the output structure.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
