Description

Technical Field

[0001] This utility model relates to the field of fiberglass exhaust gas treatment technology, and more specifically, it relates to a fiberglass exhaust gas treatment device. Background Technology

[0002] In the field of FRP (fiberglass reinforced plastic) exhaust gas treatment, the cleaning and maintenance of filter holes, the prevention of exhaust gas backflow, and the collection and treatment of foreign objects are key factors affecting the operating efficiency of the equipment. However, the FRP exhaust gas treatment devices currently on the market still have many technical defects in practical applications. These problems not only affect the exhaust gas treatment effect, but also increase the difficulty of equipment maintenance.

[0003] The primary problem is the significant deficiency in the cleaning and maintenance of filter pores. Existing waste gas treatment devices have significant defects in filtration system maintenance: First, the equipment mainly relies on the filter chamber for waste gas filtration, but long-term operation leads to gradual clogging of the filter pores; second, clogged filter pores need to be cleaned manually, increasing maintenance difficulty; third, manual cleaning not only consumes a lot of manpower, but may also affect the filtration effect due to incomplete cleaning. This deficiency in maintenance not only reduces the working efficiency of the equipment, but also increases operating costs, failing to meet the continuous operation requirements of industrial production.

[0004] More notably, there are significant deficiencies in the protection against backflow of exhaust gas. Although some equipment uses jet cleaning, this design still has significant problems in actual use: First, the built-in design of the exhaust port and nozzle results in a lack of effective isolation in the system structure; second, filtered exhaust gas can easily enter the cleaning equipment through the nozzle; third, the backflow of exhaust gas not only affects the normal operation of the cleaning equipment but may also cause secondary pollution. This inadequacy in the protection design not only affects the cleaning effect but may also lead to equipment failure and reduce the reliability of the system.

[0005] Most critically, the collection and handling of foreign objects is severely inadequate. Existing equipment has obvious defects in the unblocking process: First, the dust and foreign objects that are cleaned up fall directly to the bottom of the treatment chamber, forming a large accumulation; second, the accumulated pollutants need to be cleaned and collected manually; third, the manual cleaning process is not only time-consuming and labor-intensive, but may also cause secondary pollution due to improper operation. This inadequacy in the collection and handling method not only increases the maintenance workload, but may also affect the sanitary conditions of the working environment. Utility Model Content

[0031] Please see Figures 1-5A fiberglass reinforced plastic (FRP) waste gas treatment device includes a treatment chamber 1, a detachable cover 2 at the top of the treatment chamber 1, a movable chamber 3 rotatably disposed within the treatment chamber 1, multiple filter holes 4 on the side wall of the movable chamber 3, and a clogging removal device installed in the treatment chamber 1. The clogging removal device includes a connecting pipe 5, spray pipes 6, a connecting chamber 7, and a buffer chamber 8. The connecting pipe 5 is detachably installed on the outside of the treatment chamber 1. The input end of the buffer chamber 8 is connected to the output end of the connecting pipe 5. The input ends of the multiple connecting chambers 7 are connected to the output ends of the buffer chambers 8, and the connecting chambers 7 are installed inside the movable chamber 3. The input ends of the multiple spray pipes 6 are connected to one side of the connecting chamber 7, and a filter hole 4 is installed inside the spray pipes 6. The protective device includes a nozzle 9, a flow channel 10, an input channel 11, a sealing block 12, a fixed post 13, and a return spring 14. The nozzle 9 is located at one end of the fixed post 13 and is connected to the flow channel 10. The flow channel 10 is located inside the fixed post 13. Multiple input channels 11 are located on the side wall of the fixed post 13. The sealing block 12 is slidably disposed on the outside of the fixed post 13. The fixed post 13 is fixedly installed inside the nozzle 6. The return spring 14 is movably sleeved on the outside of the fixed post 13, and both ends of the return spring 14 are connected to the inner wall of the nozzle 6 and one side of the sealing block 12, respectively. A cleaning device is installed inside the treatment chamber 1.

[0032] An air inlet pipe 15 is connected to the side wall of the processing chamber 1. The output end of the air inlet pipe 15 is located outside the movable chamber 3. An output pipe 16 is connected to one side of the processing chamber 1. The input end of the output pipe 16 extends into the movable chamber 3.

[0033] A driven wheel 17 is detachably provided on the outside of the active chamber 3. A driving wheel 18 is provided on one side of the driven wheel 17. The driving wheel 18 meshes with the driven wheel 17. A second motor 19 is detachably provided on the outside of the processing chamber 1. The output end of the second motor 19 passes through the side wall of the processing chamber 1 and is connected to the driving wheel 18.

[0034] The processing chamber 1 is equipped with a detachable partition 20, which is located on one side of the drive wheel 18.

[0035] In this embodiment, when the device is needed, the external conveying device is first opened to deliver the exhaust gas to the processing chamber 1 through the inlet pipe 15. Then, the exhaust gas enters the movable chamber 3 through the filter hole 4. Dust and other impurities are isolated on the outside of the movable chamber 3. The filtered exhaust gas is then discharged through the output pipe 16 in the movable chamber 3 to the subsequent external equipment for further processing. When it is necessary to clean the filter hole 4, the external pressurizing device is first opened to draw in clean air. The pressurized air is then delivered to the buffer chamber 8 through the connecting pipe 5, and then delivered to each connecting chamber 7 through the buffer chamber 8. Finally, it is delivered to each nozzle 6 through the connecting chamber 7. The high-pressure gas then pushes the sealing block 12 to slide along the fixed column 13, and the sealing block 12 will squeeze the return spring 14 sleeved on the outside of the fixed column 13. The rear sealing block 12 moves to the other side of the input groove 11, and then the gas enters the flow groove 10 opened inside the fixed column 13 through the input groove 11. Then, the high-pressure gas is sprayed out through the nozzle 9. The high-pressure gas blows down the impurities blocking the filter hole 4, causing the impurities to fall to the bottom of the processing chamber 1. At the same time, the second motor 19 installed on one side of the processing chamber 1 is turned on. The second motor 19 drives the drive wheel 18 to rotate. Then, the drive wheel 18 drives the movable chamber 3 to rotate around the output pipe 16 through the driven wheel 17 that meshes with it. This causes the movable chamber 3 to drive the filter hole 4 to rotate, thereby achieving a complete cleaning of the filter hole 4. When the output pressure inside the nozzle 6 is lower than the external pressure, the reset spring 14 pushes the sealing block 12 to slide and reset, so that the sealing block 12 re-seals the nozzle 6, effectively preventing the exhaust gas from backflowing into the connecting chamber 7.

[0036] Please see Figures 1-3 As one embodiment of the cleaning device: the cleaning device includes a first motor 21, a lead screw 22 and a scraper 23. The first motor 21 is detachably installed on the outside of the processing chamber 1, the lead screw 22 is rotatably installed inside the processing chamber 1, the output end of the first motor 21 passes through the side wall of the processing chamber 1 and is connected to one end of the lead screw 22, and the scraper 23 is movably connected to the lead screw 22 through a thread.

[0037] The processing chamber 1 is detachably equipped with a slide bar 24, which is symmetrically arranged on both sides of the lead screw 22, and the scraper block 23 is slidably connected to the slide bar 24.

[0038] The bottom of the processing chamber 1 is fixedly provided with a slide rail 25, and a collection box 26 is detachably provided below the processing chamber 1. The collection box 26 is slidably installed in the slide rail 25.

[0039] Handles 27 are fixedly provided on one side of the collection box 26 and at the top of the cover 2.

[0040] More specifically, after the equipment has been used for a long time, dust and other impurities accumulate at the bottom of the processing chamber 1. At this time, the first motor 21, which can be detachably installed on the other side of the processing chamber 1, is opened. The first motor 21 drives the lead screw 22 connected to the output end to rotate. Since the scraper 23 and the lead screw 22 are connected by threads, and the scraper 23 is limited by the slide rods 24 on both sides, the scraper 23 will slide along the slide rods 24. The scraper 23 will push the dust and other impurities accumulated at the bottom of the processing chamber 1 to move, thereby pushing the accumulated dust and other impurities into the collection box 26. When the equipment stops running, the collection box 26 is pulled out from the slide rail 25 by the handle 27. Then, the dust and other impurities collected in the collection box 26 are processed and the collection box 26 is reinstalled inside the slide rail 25.

[0041] In summary, during the use or operation of the overall equipment: When the equipment needs to be used, firstly, the external conveying device is opened to transport the exhaust gas through the inlet pipe 15 to the treatment chamber 1. Then, the exhaust gas enters the movable chamber 3 through the filter hole 4. Dust and other impurities are isolated on the outside of the movable chamber 3. The filtered exhaust gas is then discharged through the outlet pipe 16 set in the movable chamber 3 to the subsequent external equipment for further treatment. When it is necessary to clean the filter hole 4, firstly, the external pressurizing device is opened to draw in clean air. Then, the pressurized air is transported to the buffer chamber 8 through the connecting pipe 5, and then through the buffer chamber 8 to each connecting chamber 7. Finally, through the connecting chamber 7, the air is transported to each nozzle 6. Then, the high-pressure gas pushes the sealing block 12 to slide along the fixed column 13, and the sealing block 12 will engage with the return spring 14 sleeved on the outside of the fixed column 13. The gas is compressed, and then the sealing block 12 moves to the other side of the input groove 11. The gas then enters the flow groove 10 inside the fixed column 13 through the input groove 11, and then the high-pressure gas is ejected through the nozzle 9. The high-pressure gas blows down the impurities blocking the filter holes 4, causing the impurities to fall to the bottom of the processing chamber 1. At the same time, the second motor 19 installed on one side of the processing chamber 1 is turned on. The second motor 19 drives the drive wheel 18 to rotate. The drive wheel 18 drives the movable chamber 3 to rotate around the output pipe 16 through the driven wheel 17, so that the movable chamber 3 drives the filter holes 4 to rotate, thereby achieving complete cleaning of the filter holes 4. When the output pressure inside the nozzle 6 is lower than the external pressure, the reset spring 14 pushes the sealing block 12 to slide and reset, so that the sealing block 12 re-seals the nozzle 6, effectively preventing the exhaust gas from flowing back into the connecting chamber 7.

[0042] After prolonged use, dust and other impurities accumulate at the bottom of the processing chamber 1. At this time, the first motor 21, which can be detachably installed on the other side of the processing chamber 1, is turned on. The first motor 21 drives the lead screw 22 connected to the output end to rotate. Since the scraper 23 and the lead screw 22 are connected by threads, and the scraper 23 is limited by the sliding rods 24 on both sides, the scraper 23 will slide along the sliding rods 24. The scraper 23 will push the dust and other impurities accumulated at the bottom of the processing chamber 1 to move, thereby pushing the accumulated dust and other impurities into the collection box 26. When the equipment stops running, the collection box 26 is pulled out from the slide rail 25 by the handle 27. Then, the dust and other impurities collected in the collection box 26 are processed and the collection box 26 is reinstalled inside the slide rail 25.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
