Description

Technical Field

[0001] This utility model relates to the field of end-of-life vehicle dismantling technology, specifically to an airbag detonation device for end-of-life vehicles. Background Technology

[0002] When a car is scrapped, it needs to be dismantled. However, during the dismantling process, airbags may accidentally deploy, causing injury. Therefore, it is necessary to remove the airbags before safely detonating them. In existing technology, to ensure the safety of airbag detonation, a dust collection mechanism is usually installed inside the detonation box. For example, Chinese patent application CN202121699629.1 discloses an airbag detonation device, and Chinese patent application CN201920418312.2 discloses another airbag detonation device, both employing similar solutions. However, because the dust particles generated during airbag detonation are small, the traditional negative pressure extraction collection method has low dust collection efficiency, and a large amount of dust may still escape during subsequent transportation, making it impractical. Therefore, this case arose from in-depth research into these problems. Utility Model Content

[0010] This invention provides a device for detonating airbags in scrapped vehicles. It offers the following advantages: This device improves upon existing detonation boxes. After connecting the terminals of the airbag to be processed to the terminal clamp, it is placed inside the detonation box. The airbag is detonated via a controller and detonation control components. Simultaneously, a negative pressure fan is activated, drawing dust generated during the airbag explosion into a dust collection hopper. Through the synergistic action of a pressurized liquid supply mechanism and an atomizing spray component, the dust-laden airflow is atomized and dust is reduced. The water mist wet-adsorbs the dust, which then enters the lower sludge collection hopper under gravity. Compared to traditional interception methods, wet adsorption offers better filtration and interception of fine dust, eliminating the risk of subsequent dust escape. When the dust concentration sensor detects that the dust concentration inside the detonation box is below a set value, the signal processing module receives the corresponding signal and controls the indicator light to flash. Workers can then open the detonation box to replace the next airbag, effectively ensuring the environmental quality of the work area and minimizing the risk of workers inhaling explosive dust.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Refer to the appendix of the instruction manual Figure 1-3It is known that, in order to address the problem that existing technologies always use traditional negative pressure extraction and collection methods to collect dust during the airbag detonation process, the dust collection efficiency is low, and a large amount of dust may still be released during subsequent transportation, this application specifically designs a scrapped vehicle airbag detonation device. A wiring clamp 2 for connecting to the airbag wiring terminal is installed inside the detonation box 1. One end of the wiring clamp 2 is plugged into the detonation control component 3, and one end of the detonation control component 3 is connected to a controller 4 via a wire. A dust concentration sensor 5 is installed inside the detonation box 1. 5. Connected to the signal processing module, an indicator light 6 is installed on the outer wall of the detonation box 1. The indicator light 6 is connected to the signal processing module. A dust collection hood 7 is installed on the top of the detonation box 1. An L-shaped bend 8 is installed on the top of the dust collection hood 7. One end of the L-shaped bend 8 is connected to a negative pressure fan 9. The air outlet of the negative pressure fan 9 is connected to the dust collection silo 11 through a dust guide pipe 10. A pressurized liquid supply mechanism is installed on the outside of the dust collection silo 11. An atomizing spray assembly is installed inside the dust collection silo 11. The outlet of the pressurized liquid supply mechanism is connected to the inlet of the atomizing spray assembly. A mud collection device is connected to the lower end of the dust collection silo 11. The mud collection hopper 12 is equipped with a slurry discharge valve 13 at its bottom. After connecting the wiring terminals of the gasbag to be treated to the wiring clamp 2, it is placed in the detonation box 1. The gasbag is detonated by the controller 4 and the detonation control component 3. At the same time as the detonation, the negative pressure fan 9 is started, which can guide the dust generated during the gasbag explosion into the dust collection silo 11. Through the synergistic action of the pressurized liquid supply mechanism and the atomizing spray component, the dust-laden airflow is atomized and dust is reduced. After the water mist wet-adsorbs the dust, it enters the lower mud collection hopper 12 under the action of gravity. Compared with the traditional interception mode, Wet adsorption is more effective at filtering and intercepting fine dust and has no risk of subsequent dust dispersion. When the dust concentration sensor 5 detects that the dust concentration in the detonation box 1 is lower than the set value, the signal processing module receives the corresponding signal and controls the indicator light 6 to flash. The staff can then open the detonation box 1 and replace it with the next airbag. This can effectively ensure the environmental quality of the work area and minimize the risk of staff inhaling explosive dust. The specific composition and working principle of the detonation component are existing technologies and have been disclosed in the technical documents published in the background section, so they will not be described in detail here.

[0017] In a preferred embodiment, the aforementioned pressurized liquid supply mechanism includes a liquid storage tank 14, a booster pump 15, an inlet pipe 16, and a drain pipe 17. The booster pump 15 is located on top of the liquid storage tank 14. One end of the inlet pipe 16 is connected to the inlet end of the booster pump 15, and the other end extends into the liquid storage tank 14. One end of the drain pipe 17 is connected to the outlet end of the booster pump 15, and the other end is connected to the atomizing spray assembly. The atomizing spray assembly includes a mounting frame 18, an annular pipe 19, and an atomizing nozzle 20. The mounting frame 18 is located inside the dust collection silo 11, and the annular pipe 19 is located inside the mounting frame 18. The atomizing nozzles 20 are arranged coaxially with the dust guide pipe 10 and arranged in a ring array on the lower side wall of the ring pipe 19. In use, the liquid adsorbent in the storage tank 14 is extracted through the inlet pipe 16 by the booster pump 15, and after being pressurized, it is supplied to the ring pipe 19 through the drain pipe 17. Under the action of water head pressure, the liquid adsorbent is sprayed out through the atomizing nozzles 20. A large amount of liquid water mist comes into contact with the dust-laden airflow drawn in by the negative pressure fan 9, which can fully adsorb the particulate matter in the airflow. The adsorbed particulate matter enters the lower mud collection hopper 12 under the action of gravity. The structure is reliable and the operating cost is low.

[0018] In the specific implementation process, as a preferred setting, the above-mentioned liquid storage tank 14 is filled with water or alkaline solution. Different types of liquid adsorbents can be selected for different models of airbags. If the explosion dust is only talc or corn starch, it can be adsorbed with water; if it is some older models, the explosion dust may contain some toxic and harmful dust such as sodium azide, and it is necessary to use alkaline solution for adsorption.

[0019] In the specific implementation process, as a preferred configuration, the above-mentioned liquid storage tank 14 is equipped with a liquid level sensor, and the top of the liquid storage tank 14 is equipped with a liquid replenishment port 21, so as to facilitate timely replenishment of liquid adsorbent and ensure the overall stability of equipment operation.

[0020] In the specific implementation process, as a preferred configuration, the upper part of the dust collection silo 11 is a cylindrical silo with an exhaust hole 22 on the upper end face, and the lower part of the dust collection silo 11 is a cone-shaped hopper, which facilitates the collection and temporary storage of the sludge generated after adsorbing dust, and centralized transfer and treatment.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
