Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment equipment, and in particular to a waste gas treatment device for the production of iron trough castable. Background Technology

[0002] Waste gas treatment equipment is a device used to treat waste gas generated during industrial production, aiming to reduce or eliminate pollutants in the waste gas to meet environmental protection standards.

[0003] Common waste gas treatment equipment typically uses wet scrubbing to wash waste gas, which can remove harmful impurities. However, it lacks cleaning components and cannot clean the filter plates inside the scrubbing drum. Over time, the surface of the filter plates can become clogged with impurities, affecting the air outlet efficiency of the scrubbing drum. Furthermore, the lack of a circulating filter component means that the water used for waste gas washing cannot be recycled, resulting in water waste, increased operating costs, and reduced practicality of the waste gas treatment equipment.

[0004] Therefore, to address the lack of cleaning and circulating filtration components in the aforementioned waste gas treatment equipment, which prevents the cleaning of the filter plates inside the washing drum and the recycling of water, a waste gas treatment device for iron trough casting production can be designed. By starting the drive motor, the rotating shaft and connecting pin can be rotated. When the connecting pin rotates, the scraper will rotate along the left side of the first filter plate, thereby scraping off impurities adhering to the left surface of the first filter plate, preventing the first filter plate from becoming clogged due to long-term use, thus achieving the effect of cleaning the filter plate. Furthermore, a water pump can transport the filtered water to the second control valve, which in turn can transport the water to the inside of the water pipe, achieving the purpose of circulating filtration and reuse, avoiding water waste and reducing operating costs. Utility Model Content

The positioning hole 44 facilitates the connection between the rotating shaft 42 and the connecting pin 45. When the connecting pin 45 rotates, the scraper 46 will rotate along the left side of the first filter plate 43. The rotation of the scraper 46 will scrape off the impurities adhering to the left side surface of the first filter plate 43. The fallen impurities will be discharged along with the water in the washing drum 3 through the guide pipe 21, thereby achieving the effect of cleaning the filter plate. This design improves practicality and allows the filtered water in the filter box 57 to be extracted via the water pump 56 and transported to the water supply pipe 53 via the water pump 55. The first control valve 54 controls the flow rate of the water in the water supply pipe 53, which then delivers water to the second control valve 52 on the top of the mounting base 51.

The purification box 17 can then perform final purification and filtration on the gas.

[0028] Please see 1- Figure 6In this embodiment, two carbon fiber adsorption mesh plates 18 are symmetrically arranged inside the purification box 17. A sealing door 19 is installed on the front side of the purification box 17, and an exhaust pipe 20 is connected to the lower right side of the purification box 17. The carbon fiber adsorption mesh plates 18 can adsorb harmful impurities in the gas. The sealing door 19 can be used to seal the purification box 17 to prevent gas leakage.

Part 25, guide blocks 26 are symmetrically arranged on the front and rear sides of the second filter plate 23 and the spherical carbon filter plate 24, and guide grooves are opened on the front and rear sides of the filter box 57 corresponding to the positions of the guide blocks 26. The second filter plate 23 can be used to filter larger impurities in the mixed liquid, and the spherical carbon filter plate 24 can filter harmful metal impurities and fine particles in the liquid. The U-shaped connector 25 and the guide blocks 26 facilitate the installation and removal of the second filter plate 23 and the spherical carbon filter plate 24, improving practicality.

By activating the electric push rod 27, it can push the connecting plate 22 to the left. When the connecting plate 22 moves to the left, it will drive the second filter plate 23 and the spherical carbon filter plate 24 to move synchronously, thereby facilitating the disassembly and cleaning of the second filter plate 23 and the spherical carbon filter plate 24.

[0029] During operation, exhaust gas is conveyed to the first fan 10 via the air inlet pipe 11. The first fan 10 then conveys the exhaust gas to the washing drum 3 via the air delivery pipe 12, facilitating the washing drum 3's removal of impurities from the exhaust gas. Water is conveyed from the water delivery pipe 53 to the distributor 7 via the water pipe 6, and the distributor 7 evenly distributes the water to multiple spray heads 8. The spray heads 8 spray water at high pressure, achieving the effect of removing impurities from the exhaust gas through sedimentation washing. Starting the drive motor 41 rotates the rotating shaft 42, which in turn rotates the connecting pin 45. The positioning hole 44 facilitates the connection between the rotating shaft 42 and the connecting pin 45. When the connecting pin 45 rotates, the scraper 46 rotates along the left side of the first filter plate 43, scraping off impurities adhering to the left surface of the first filter plate 43. The fallen impurities are discharged along with the water in the washing drum 3 through the guide pipe 21, thus cleaning the filter plate. At the same time, the second fan 14 and the exhaust pipe 13 can extract the gas after rinsing the washing drum 3, and deliver the gas to the purification box 17 through the air supply pipe 16. The purification box 17 can perform final purification and filtration on the gas, and the purified and filtered gas can be discharged through the exhaust pipe 20. The water filtered in the filter box 57 can be extracted through the water suction pipe 56 and delivered to the water supply pipe 53 through the water pump 55. The first control valve 54 can be used to control the flow rate of water in the water supply pipe 53. The water supply pipe 53 can deliver water to the second control valve 52 on the top of the mounting base 51, and the second control valve 52 can deliver water to the inside of the water pipe 6, thus achieving the purpose of recycling. This not only avoids the waste of water resources, but also reduces the operating cost.

[0030] Through the above steps, by setting up cleaning and circulating filtration components, not only can the filter plates inside the washing drum 3 be cleaned, but the water after the waste gas is washed can also be recycled. This solves the problem that common waste gas treatment equipment, due to the lack of cleaning and circulating filtration components, is prone to filter plate surface blockage by impurities, affecting the air outlet efficiency of the washing drum 3, and causing the washed water to be unable to be recycled, thus wasting water resources, increasing operating costs, and reducing the practicality of the waste gas treatment equipment.
