[0017] Beneficial effects of the present invention:
[0018] 1. The smoke purification equipment for fastener production is provided with a purification module. The arc-shaped arrangement of the first purification sheet and the second purification sheet inside the purification column forms a multi-stage filtering and purification structure, which can filter and purify the smoke in multiple stages, can more effectively remove harmful substances in the smoke, and improve the purification effect. The arc-shaped arrangement of the first purification sheet and the second purification sheet increases the inner surface area of the purification column, effectively increases the surface area in contact with the smoke, and improves the purification efficiency. When the smoke passes through these purification sheets, it can more fully contact the purification medium, so that it can be purified more thoroughly. One end of the purification column is fixedly connected to one end of the cylinder, and a gap is left between the other end and the inner wall of the purification column. This arrangement can reduce the resistance loss of the smoke when passing through the purification column, ensure the smooth flow of the smoke, and improve the purification efficiency. One end of the purification column is fixedly connected to one end of the cylinder, and a gap is left between the other end and the inner wall of the purification column. This arrangement can increase the flow distance of the smoke, prolong its purification contact time, and achieve better purification effect.
[0019] 2. This type of smoke purification equipment for fastener production is equipped with a suction module. The smoke treated by the purification column is sucked into the suction box and enters the deposition room for further treatment. In the deposition room, the guide tube and the guide blade are arranged to make the smoke flow more evenly inside the suction module and guide the smoke to pass smoothly through the deposition room, ensuring that the inhaled smoke can fully contact the deposition area and improve the deposition efficiency. The guide blades can increase the contact area between the smoke and the air and increase the residence time of the smoke in the deposition room, which is conducive to the precipitation and separation of particulate matter and pollutants. The two arc-shaped return sheets can control the flow direction of the smoke inside the connecting pipe, prevent turbulence and eddy currents in the smoke during the flow, and maintain the stable flow of the smoke. At the same time, the gap between the two return sheets can ensure the smooth flow of the smoke, avoid blockage, and ensure the normal operation of the suction module.
[0020] 3. The smoke purification equipment for fastener production is provided with a filter component. The adsorption rod is a magnetic material that can absorb some tiny particles and enhance the filtering effect. The guide plate is located inside the first purification room, close to the side of the air inlet. The inclined setting of the guide plate helps to guide the smoke airflow entering the purification box to pass through the filter component smoothly, avoid uneven airflow and blockage, and improve the filtering efficiency. Through the synergistic effect of the filter element, the adsorption rod and the guide plate, the smoke processing process can be optimized to ensure that the smoke is fully contacted and processed inside the purification box, thereby improving the efficiency and thoroughness of smoke purification. When the filter element needs to be cleaned, the vacuum cleaner is started to generate negative pressure, and the negative pressure is transmitted to the inside of the filter element through the connecting pipe.

[0041] The untreated smoke passes through the filter assembly of the first purification room 5 for dust filtration, then enters the second purification room 6, passes through the air inlet net and enters the purification column 11, where the purification medium further purifies the smoke, and then enters the cylinder 14 through the air outlet net 15, and then passes through the purification cylinder 17 inside the cylinder 14 for treatment, and finally the purified air is discharged. In the purification column 11, the smoke contacts the purification medium and undergoes further chemical or physical treatment.
[0042] like Figure 5 , Figure 6 As shown, a plurality of first purification sheets 12 are arranged on the inner circumference of the purification column 11, and a second purification sheet 13 is arranged between two first purification sheets 12, the first purification sheet 12 is arranged in an arc shape, and the second purification sheet 13 is arranged in an arc shape opposite to the first purification sheet 12, one end of the purification columns 11 is fixedly connected to one end of the cylinder 14, and a gap is left between the other end of the purification columns 11 and the inner wall of the purification column 11, one end of the second purification sheet 13 is fixedly connected to the inner wall of the purification column 11, and a gap is left between the other end of the second purification sheet 13 and the outer wall of the cylinder 14;
[0043] Untreated smoke enters the second purification room 6, passes through the air inlet net and enters the purification column 11. The smoke passes through the arc-shaped arrangement of the first purification sheet 12, contacts with the purification medium and is filtered and purified. The first purification sheet 12, the second purification sheet 13 and the purification tube 17 can all be configured to be made of active manganese oxide material, which is a commonly used catalyst and adsorbent with high adsorption capacity and catalytic activity, and can effectively remove organic matter, gaseous pollutants and odor substances in the smoke. It is also often used as a purification medium, covering the surface of the purification sheet and the purification tube 17, and then purifying. After being purified by the first purification sheet 12, the smoke continues to pass through the arc-shaped arrangement of the second purification sheet 13 and is purified again.

Under the action of the negative pressure, the dust and dirt on the surface of the filter element 9 are sucked into the inside of the vacuum cleaner 30, and the cleaning process is completed. By cleaning the filter element 9 with the vacuum cleaner 30, the dust and dirt on the surface of the filter element 9 can be regularly removed, the permeability and filtration efficiency of the filter element 9 can be maintained, thereby ensuring the continuous and stable purification effect.
