DETAILED DESCRIPTION

[0020] As Figures 1-4As shown, a chemical production safety dust falling device, stirring tank 7 is provided with mounting bracket 4, mounting bracket 4 is provided with liftable dust cover 1, dust cover 1 upper end necking is communicated with suction fan 12 through dust removal pipe 11, suction fan 12 is communicated with ash storage tank 13, dust cover 1 lower end opening is horn-shaped structure, dust cover 1 lower end opening circle is hinged with baffle 6, baffle 6 outer surface and dust cover 1 between being provided with cylinder 5;

[0021] Cylinder 5 drives baffle 6 to rotate and makes the end of baffle 6 close to the surface of stirring tank 7 body, a plurality of baffles 6 rotate and enclose the upper end of stirring tank 7 inside dust cover 1. First, dust cover 1 is set above stirring tank 7 through mounting bracket 4, and it is ensured that it can smoothly operate lifting. When dust control is needed for stirring tank 7, dust cover 1 is lowered to the appropriate position to cover the upper end opening part of stirring tank 7. In order to improve the effect of dust collection and dust falling, cylinder 5 is used to drive baffle 6 to rotate, so that one end of baffle 6 is close to the outer wall surface of stirring tank 7. In this way, a plurality of baffles 6 can form a closed space after rotating, which encloses the upper end of stirring tank 7 inside dust cover 1, and the necking structure formed between baffles 6 helps to further enhance the dust collection effect. Finally, start suction fan 12, connect to the upper end necking of dust cover 1 through dust removal pipe 11, and suck the generated dust into ash storage tank 13 for storage.

[0022] Because dust cover 1 can completely cover the upper part of stirring tank 7, and tightly fit with the stirring tank body through baffle 6, the overflow of dust is reduced.

[0023] Dust cover 1 can be adjusted in lifting according to actual needs, which facilitates the operation and maintenance of the equipment; improve the safety of working environment, effectively reduce the concentration of suspended dust in the air, reduce the risk of explosion and health; four is convenient for cleaning and dust treatment, the design of ash storage tank 13 makes it easy to clean and centralized treatment after dust collection, which is conducive to environmental protection.

[0024] In the preferred embodiment, the upper surface of the dust hood 1 is provided with at least one guide rod 2, which is slidably connected to the mounting frame 4. The mounting frame 4 is also provided with a lifting mechanism 9, which is connected to the dust hood 1 via a pull rope 8. First, the dust hood 1 is lifted to an appropriate height using the lifting mechanism 9 and the pull rope 8 on the mounting frame 4 to facilitate the operation of the mixing tank 7. When dust control of the mixing tank 7 is required, the lifting mechanism 9 is activated and the pull rope 8 is released, allowing the dust hood 1 to descend smoothly under its own weight to cover the upper opening of the mixing tank 7. During this process, the guide rod 2 plays a crucial guiding role, ensuring that the dust hood 1 descends accurately to the designated position along a predetermined trajectory. To prevent the dust hood 1 from falling too quickly and causing impact or damage, the lifting mechanism 9 can also limit its descent speed, ensuring the safety and stability of the operation. After completing the work, the dust hood 1 is lifted back to its original height using the lifting mechanism 9 and the pull rope 8, preparing for the next operation.

[0025] The height of the dust hood 1 can be easily adjusted by the lifting mechanism 9, which not only facilitates the operation and maintenance of the equipment but also improves work efficiency. Secondly, the presence of the guide rod 2 ensures the stability and accuracy of the dust hood 1 during the lifting process, reducing the risk of malfunctions or accidents caused by positional deviation. Furthermore, by controlling the descent speed of the dust hood 1, not only is the equipment protected from damage, but personnel safety is also guaranteed. Finally, the overall design makes the entire system more automated and intelligent, which helps to improve the safety level of the working environment and management efficiency.

[0026] In the preferred embodiment, the mounting bracket 4 is installed on the top wall via a hanger 401. The mounting bracket 4 is securely installed on the top wall via the hanger 401. This ensures a strong and reliable connection between the hanger 401 and the mounting bracket 4, capable of withstanding the weight of components such as the dust hood 1, guide rod 2, and elevator 9, as well as the forces generated during operation. After installation, the height of the dust hood 1 can be adjusted via the elevator 9 to maintain a high position when not in use, without obstructing the operation of the mixing tank 7. When dust control is required, the elevator 9 is activated to release the pull rope 8, allowing the dust hood 1 to descend smoothly under gravity to cover the upper opening of the mixing tank 7. During this process, the guide rod 2 plays a crucial guiding role, ensuring the dust hood 1 descends accurately to the designated position, and the elevator 9 limits the descent speed to ensure safety. The cylinder 5 drives the baffle 6 to rotate and approach the surface of the mixing tank 7, forming a closed space and improving dust collection efficiency.

[0027] In the preferred embodiment, the upper constricted pipe of the dust hood 1 is connected to the dust removal pipe 11 via the telescopic pipe 3. This adapts to the position changes of the dust hood 1 during lifting and lowering, ensuring a stable connection with the dust removal system regardless of whether the dust hood 1 is operating at a high or low position, thus preventing dust leakage.

[0028] In the preferred embodiment, the two ends of the baffle 6 are provided with bevels, and the plurality of baffles 6 form a necked structure after rotation, and the bevels of adjacent baffles abut each other. As shown in Figures 3-4 When dust control of the mixing tank 7 is needed, first, the dust hood 1 is lowered to the appropriate position to cover the upper end opening of the mixing tank 7. Then, the baffle 6 is driven to rotate by the cylinder 5, so that one end of the baffle 6 is close to the outer wall surface of the mixing tank 7, and because the two ends of the baffle 6 are provided with bevels, the bevels of adjacent baffles can abut each other after the plurality of baffles 6 are rotated, thereby forming a downward necked structure. This necked structure helps to further guide and concentrate the dust generated from the mixing tank 7 into the dust hood 1, and ultimately be collected by the dust storage tank 13 through the telescopic pipe 3 and the dust removal pipe 11.

[0029] In the preferred embodiment, the dust hood 1 is provided with a first support rod 501, the baffle 6 is provided with a second support rod 502, and the two ends of the cylinder 5 are hinged to the first support rod 501 and the second support rod 502, respectively. The first support rod 501 is longer than the second support rod 502. The first support rod 501 installed on the dust hood 1 and the second support rod 502 installed on the baffle 6 are correctly connected, and the two ends of the cylinder 5 are hinged to the first support rod 501 and the second support rod 502, respectively. When dust control of the mixing tank 7 is needed, the cylinder 5 is started, and the baffle 6 is driven to rotate by the telescopic action of the cylinder 5. Because the first support rod 501 is longer than the second support rod 502, it provides a larger range of rotation angle for the baffle 6, so that the baffle 6 can more effectively close to the outer wall surface of the mixing tank 7, ensuring that the plurality of baffles 6 can be closely fitted after rotation, forming an effective closed space. This not only improves the dust collection efficiency, but also prevents dust from escaping from the gap between the baffles.

[0030] In the preferred embodiment, the dust hood 1 is further provided with a distance sensor 10, and the distance sensor 10 is electrically connected to the elevator 9. When dust control of the mixing tank 7 is needed, the system is started, and the distance sensor 10 starts to monitor the distance between the dust hood 1 and the mixing tank 7 in real time. According to the pre-set safe distance or optimal operating distance, the distance sensor 10 sends a signal to the elevator 9 to automatically adjust the height of the dust hood 1.

[0031] When the dust hood 1 is lowered too much, the distance sensor 10 will trigger the elevator 9 to lift the dust hood 1 through the pull rope 8; on the contrary, if the dust hood 1 is too high, it can also be lowered to the appropriate height through the control system. In the whole process, the cylinder 5 drives the baffle 6 to rotate and close to the outer wall surface of the mixing tank 7, further optimizing the sealing effect.

[0032] The above-mentioned embodiments are only preferred technical solutions of the present application, and should not be regarded as limiting the present application, and the protection scope of the present application should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features recorded in the claims as the protection scope. That is, the equivalent replacement improvements within the scope are also within the protection scope of the present application.
