Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, and in particular to a waste gas purification treatment device. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted by humans during production and daily life. Emitted waste gas has a strong odor, seriously pollutes the environment and affects human health. Waste gas contains many types of pollutants with very complex physical and chemical properties and varying degrees of toxicity. Therefore, waste gas treatment equipment is needed to purify and treat waste gas.

[0003] In waste gas treatment, pipes are used to guide the waste gas. Since the waste gas contains large particulate impurities, it needs to be filtered. Generally, waste gas filter screens or filter cloths are used. However, after long-term use, the filter screens accumulate a lot of impurities, which reduces the efficiency of waste gas flow. Therefore, they need to be replaced. This means that each replacement requires stopping the waste gas flow and disassembling and reassembling. This is inconvenient for actual use. Utility Model Content

[0004] The purpose of this utility model is to provide a treatment device for exhaust gas purification, which solves the problem that after a long period of use, the filter screen in exhaust gas purification will accumulate a lot of impurities, which will reduce the efficiency of exhaust gas flow. Therefore, it is necessary to replace it, which means that each replacement requires stopping the exhaust gas flow and disassembling and reassembling, which is inconvenient for actual use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A waste gas purification treatment device includes a waste gas pipeline with extension shells on both sides. The waste gas pipeline is opened relative to the two extension shells, and a sealing plate is provided at the opening. A rotating shaft is rotatably connected inside each of the two extension shells. A roller is slidably sleeved on the surface of each of the two rotating shafts. A filter screen is wound on each of the two rollers. A cleaning mechanism for cleaning the filter screen is provided inside each extension shell. A motor is fixedly installed on the side wall of each extension shell, and the output shaft port of the motor is fixedly connected to the rotating shaft.

[0007] Preferably, a fixing block is fixedly installed on the top of each of the two extended shells, and a U-shaped rod is slidably connected to the surface of each fixing block. A screw rod is rotatably passed through the surface of the U-shaped rod, and the screw rod is threadedly connected to the fixing block. A sealing strip is fixedly installed on the surface of the sealing plate.

[0008] Preferably, the cleaning mechanism includes a cleaning roller and a driven turntable. A connecting shaft is fixedly inserted inside the cleaning roller and rotates through the extension shell. The driven turntable is fixedly installed on the surface of the connecting shaft. An active turntable is fixedly installed on the surface of the output shaft of the motor. The active turntable and the driven turntable are connected by belt drive. The cleaning roller is located at the bottom of the filter screen.

[0009] Preferably, a fixing rod is fixedly installed inside the two extended shells near the upper and lower inner walls, and a rubber strip is fixedly installed on the surface of each fixing rod, with the upper and lower sides of the filter screen in contact with the rubber strip.

[0010] Preferably, the cleaning mechanism further includes two nozzles, which are fixedly installed inside the extension shell near the upper and lower sides. Each of the two extension shells has a nozzle on the side closest to each other. A filter screen is located between the two nozzles. An air pump is fixedly installed on the side wall of the extension shell. The air outlet of the air pump is connected to a connecting pipe. Both nozzles are connected to the connecting pipe.

[0026] Reference Figure 1-5 A waste gas purification device includes a waste gas duct 1, with extension shells 2 on both sides of the waste gas duct 1. The waste gas duct 1 is open relative to the two extension shells 2, and a sealing plate 15 is provided at the opening. A rotating shaft 7 is rotatably connected inside each of the two extension shells 2. A roller 6 is slidably fitted onto the surface of each of the two rotating shafts 7. A filter screen is wound onto each of the two rollers 6. A cleaning mechanism for cleaning the filter screen is provided inside the extension shells 2. A motor 9 is fixedly installed on the side wall of the extension shell 2. The output shaft port of the motor 9 is fixedly connected to the rotating shaft 7. In use, waste gas is introduced from the bottom of the waste gas duct 1, and the two rollers 6 are respectively fitted onto the surfaces of the two rotating shafts 7. The two rollers 6 can be unwound and wound simultaneously. The roller 6 closer to the motor 9... The drum 6 is for winding. Therefore, after the filter screen in the exhaust gas duct 1 has been used for a period of time, the motor 9 can be started. The motor 9 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the drum 6 to rotate. The two drums 6 rotate synchronously through the filter screen, so that the fully used filter screen can be wound up, and the unused filter screen can be unwound and placed in the exhaust gas duct 1, thereby realizing automatic replacement of the filter screen without having to disassemble and replace it every time it is used, saving time and reducing labor. When the filter screen is completely used up, the sealing plate 15 can be opened, and then the two drums 6 can be pulled out from the two rotating shafts 7. During the filter screen replacement process, the cleaning mechanism can be used to clean the filter screen, thereby reducing the phenomenon that large particles of impurities are squeezed after the filter screen is wound up, which makes it inconvenient to clean after subsequent disassembly.

[0027] Furthermore, a fixing block 19 is fixedly installed on the top of each of the two extension shells 2. A U-shaped rod 17 is slidably connected to the surface of the fixing block 19. A screw 18 is rotatably passed through the surface of the U-shaped rod 17. The screw 18 and the fixing block 19 are threadedly connected. A sealing strip 16 is fixedly installed on the surface of the sealing plate 15. The sealing plate 15 is removable, which facilitates the replacement of the roll 6 and the filter screen. When disassembling, simply rotate the screw 18 to move the U-shaped rod 17, so that the U-shaped rod 17 no longer squeezes the sealing plate 15. When installing, simply align the sealing plate 15 with the opening, and then rotate the screw 18 in the opposite direction to squeeze the sealing plate 15 with the U-shaped rod 17.

[0028] Furthermore, the cleaning mechanism includes a cleaning roller 8 and a driven turntable 11. A connecting shaft is fixedly inserted inside the cleaning roller 8, and the connecting shaft rotates through the extension shell 2. The driven turntable 11 is fixedly installed on the surface of the connecting shaft. An active turntable 10 is fixedly installed on the surface of the output shaft of the motor 9. The active turntable 10 and the driven turntable 11 are connected by belt drive. The cleaning roller 8 is located at the bottom of the filter screen. During use, when the motor 9 drives the drum 6 to wind, its output shaft will also drive the active turntable 10 to rotate. The active turntable 10 drives the driven turntable 11 to rotate through the belt. The driven turntable 11 drives the connecting shaft to rotate, and the connecting shaft drives the cleaning roller 8 to rotate, thereby cleaning the filter screen.

[0029] Furthermore, fixing rods 4 are fixedly installed inside the two extended shells 2 near the upper and lower inner walls. Rubber strips 5 are fixedly installed on the surface of the fixing rods 4. The upper and lower sides of the filter screen are in contact with the rubber strips 5. By setting the rubber strips 5, the amount of exhaust gas entering the interior of the two extended shells 2 is reduced as much as possible.

[0030] Furthermore, the cleaning mechanism also includes two nozzles 12, which are fixedly installed inside the extension shell 2 near the upper and lower sides. Each of the two extension shells 2 has a nozzle on its side closest to each other. The filter screen is located between the two nozzles 12. An air pump 14 is fixedly installed on the side wall of the extension shell 2. The air outlet of the air pump 14 is connected to a connecting pipe 13. Both nozzles 12 are connected to the connecting pipe 13. The side wall of the extension shell 2 is provided with an exhaust port 20 with a valve. During the cleaning process, the air pump transmits high-pressure air to the connecting pipe 13, which then enters the nozzles 12. The nozzles 12 are used to clean the upper and lower sides of the filter screen, improving the cleaning effect. When using the air pump, the valve of the exhaust port 20 can be opened to allow the high-pressure gas to be discharged.

[0031] Furthermore, protruding rods 3 are fixedly installed inside the two extended shells 2 near the bottom wall. The protruding rods 3 can keep the impurities scraped off by the rubber strips 5 during the movement of the filter screen in a fixed space and prevent them from falling into the exhaust pipe 1.

[0032] In summary, during use, exhaust gas is introduced from the bottom of the exhaust duct 1. Two rollers 6 are respectively fitted onto the surfaces of two rotating shafts 7. The two rollers 6 can be used to unwind one roller and rewind the other. The roller 6 closer to the motor 9 is used for rewinding. Therefore, after the filter screen in the exhaust duct 1 has been used for a period of time, the motor 9 can be started. The motor 9 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the rollers 6 to rotate. The two rollers 6 rotate synchronously through the filter screen, so that the fully used filter screen can be wound up, and the unused filter screen can be unwound and placed in the exhaust duct. In channel 1, automatic filter replacement is achieved without the need for disassembly and replacement every time, saving time and reducing labor. Once all the filter screens are used, the sealing plate 15 can be opened, and the two rollers 6 can be pulled out from the two rotating shafts 7. During filter replacement, a cleaning mechanism can be used to clean the filter screens, reducing the problem of large particles being compressed after tangling, which would make subsequent cleaning difficult. The sealing plate 15 is removable, facilitating the replacement of the rollers 6 and filter screens; disassembly only requires turning the screw. 18. The screw 18 drives the U-shaped rod 17 to move, thus preventing the U-shaped rod 17 from pressing against the sealing plate 15. During installation, simply align the sealing plate 15 with the opening, then rotate the screw 18 in the opposite direction to cause the U-shaped rod 17 to press against the sealing plate 15. During operation, as the motor 9 drives the drum 6 to wind, its output shaft also drives the active turntable 10 to rotate. The active turntable 10 drives the driven turntable 11 to rotate via a belt. The driven turntable 11 drives the connecting shaft to rotate, and the connecting shaft drives the cleaning roller 8 to rotate, thereby cleaning the filter screen. To achieve cleaning, rubber strips 5 are installed to minimize the amount of exhaust gas entering the two extension shells 2 during the flow of exhaust gas. During the cleaning process, an air pump is used to transmit high-pressure air to the connecting pipe 13, which then enters the spray pipe 12. The spray pipe 12 is used to clean the upper and lower sides of the filter screen, improving the cleaning effect. When using the air pump, the valve of the exhaust port 20 can be opened to allow the high-pressure gas to be discharged. The protruding rod 3 is designed to keep the impurities scraped off by the rubber strips 5 during the movement of the filter screen in a fixed space, preventing them from falling into the exhaust gas pipe 1.
