Description

Technical Field

[0001] This utility model relates to the field of diffusion welding fume filtration technology, and in particular to a diffusion welding fume filtration device. Background Art

[0002] Diffusion welding fume filtration technology is a method for treating fumes generated during diffusion welding processes. This technology utilizes high-efficiency filters and adsorption materials to capture and adsorb solid particles and gaseous pollutants in the fumes, purifying them through physical and chemical processes, thus protecting the working environment and the health of personnel.

[0003] A search revealed Chinese Patent Publication No. CN204043013U, which discloses an oil fume filtration device. This device includes a housing with an air inlet and an air outlet, a motor, and a fan. A guide ring is located on the front side of the air inlet of the centrifugal fan, and a support frame is mounted on the guide ring. A dynamic fan blade is installed on the support frame, and the dynamic fan blade is opposite to the air inlet direction of the centrifugal fan, allowing the airflow to drive the dynamic fan blade to rotate. An oil baffle is located on the outer side of the dynamic fan blade, and an oil cup is located at the bottom of the oil baffle. In this invention, oil droplets rub and condense on the rotating dynamic fan blade, and then are thrown towards the oil baffle under centrifugal force, separating the oil fumes from the airflow. This device features a simple structure, convenient cleaning, reliable operation, and long service life, effectively eliminating oil fume pollution to the air and building exteriors, thus contributing to environmental protection.

[0004] The beneficial effects mentioned in the aforementioned patent specification state that "since the dynamic fan blades are driven by airflow, the wind resistance caused by the airflow is very small, so no great noise is generated." Although the aforementioned patent does not generate great noise, it is impossible to quickly disassemble the filter screen in this filtration device during actual use. This means that after long-term use, the entire device needs to be disassembled for cleaning, which greatly increases the workload of the staff. Therefore, a diffusion welding fume filtration device is proposed to solve the above problems. Utility Model Content

At this time, spring 16, button 12 and limit block 13 will start to work, so as to reset them and complete the engagement. The oil fumes filtered by filter 9 will pass through filter 9. At this time, nozzle 26 can be started to spray oil fume purification liquid to settle the harmful substances in the oil fumes.

[0038] Then, the motor 19 on the inner wall of the bottom block 18 is started. At this time, the motor 19 will drive the turntable 20 to rotate. The support block 17 here serves to support the turntable 20. When the turntable 20 rotates, it drives the short shaft 21 and the long shaft 22 on it to rotate, thereby driving the scraper 23 to move back and forth on the left side of the area, pushing the sediment on it into the storage box 27 for collection. The clean gas will be discharged to the outside through the vent 25.
