The key to this kind of dust collector lies in the material and structure of the filter bag, which jointly determine the dust removal efficiency and performance of the dust collector.
[0003] The main functions of the flat bag dust collector include: High-efficiency dust removal: The flat bag dust collector can effectively capture and remove dust particles in the gas, especially for the capture of fine, dry, and non-fibrous dust is particularly remarkable. Its high-efficiency dust removal ability helps to maintain the cleanliness of the production environment, protect the health of workers, and reduce the damage of dust to equipment. Environmental protection: By reducing dust emissions, the flat bag dust collector plays a positive role in environmental protection. It helps to reduce the dust concentration in the atmosphere, improve air quality, and reduce the occurrence of environmental pollution phenomena such as haze. Improving product quality: In some industries with high requirements for the production environment, such as food processing and pharmaceutical manufacturing, the flat bag dust collector can ensure the cleanliness of the production environment, thus avoiding dust pollution to products and improving the quality and safety of products. Energy conservation and emission reduction: During the operation of the flat bag dust collector, through optimized design and control strategies, it can reduce energy consumption and emissions. At the same time, due to its high-efficiency dust removal ability, the need for subsequent treatment processes can be reduced, further reducing production costs and energy consumption.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution for a pulse-jet system of a flat bag dust collector: including a dust collector main body 1 and a main body support frame 2, and the dust collector main body 1 is fixedly installed at the upper end of the main body support frame 2;

An interference connection is provided at the bottom opening of the ash discharge trough 4 with a sealed bottom cover 5, so as to block and seal the bottom opening of the ash discharge trough 4 through the sealed bottom cover 5. A rotating motor 6 is fixedly installed and supported at the rear end of the main body support frame 2. The front end transmission shaft part of the rotating motor 6 is fixedly installed with a driving long shaft 7, and the driving long shaft 7 is rotatably connected through a rotating shaft in the middle of the ash discharge trough 4. A plurality of ash discharge blades 8 are fixedly installed on the outer surface of the middle part of the driving long shaft 7, and the number of the ash discharge blades 8 is several, and they are symmetrically distributed in sequence on the outer surface of the middle part of the driving long shaft 7;
[0026] An air outlet groove 9 is provided at the upper side end of the dust collector main body 1, and the number of the air outlet grooves 9 is two, which are symmetrically distributed at the upper side end of the dust collector main body 1. An air outlet fan 10 is fixedly installed and supported on the inner wall of the air outlet groove 9, so that the air entering the dust collector main body 1 is discharged outward through the cooperation of the air outlet fan 10 and the air outlet groove 9. A horizontal support frame 11 is fixedly installed on the upper end inner wall of the dust collector main body 1, and a flat filter bag 12 for filtering the dust-containing flue gas is fixedly installed on the upper end of the horizontal support frame 11. A support side frame 13 is fixedly installed on the side of the upper end of the dust collector main body 1 away from the air outlet groove 9. A gas storage tank 14 is fixedly installed on the upper end of the support side frame 13, and compressed gas is filled in the gas storage tank 14. An air outlet 15 is provided at the lower end of the gas storage tank 14, and the number of the air outlets 15 is several, which are symmetrically distributed in sequence at the lower end of the gas storage tank 14. The lower end opening of the air outlet 15 is rotationally communicated with an air outlet pipe 16 through a blowing valve and a rotating joint, and the air outlet pipe 16 is rotationally connected to the upper top end of the dust collector main body 1 through a rotating shaft. A nozzle 17 for blowing and cleaning the flat filter bag 12 is fixedly installed and communicated at the bottom of the air outlet pipe 16. A driving motor 18 is fixedly installed and supported on the outer side of the support side frame 13. A first synchronous pulley 19 is fixedly installed on the inner side transmission shaft part of the driving motor 18. The outer end of the first synchronous pulley 19 is connected by a synchronous belt to a second synchronous pulley 20, and the second synchronous pulley 20 is fixedly installed on the outer curved surface of the side end of the air outlet pipe 16. The air outlet pipes 16 are mutually driven by the synchronous belt and the synchronous pulley.
[0027] Working principle: When in use, the utility model discharges the dust-containing flue gas into the ash hopper 3 through the air inlet pipe 21. When the dust-containing flue gas is discharged into the ash hopper 3, due to the sudden expansion of the air flow cross-section, the larger particle impurities in the dust-containing flue gas will fall to the inner bottom of the ash hopper 3 under the action of gravity. At the same time, by controlling the opening of the air outlet fan 10, when the air outlet fan 10 is opened, it will cooperate with the air outlet groove 9 to discharge the gas inside the dust collector main body 1 outward. When the gas inside the dust collector main body 1 is discharged outward, the dust-containing flue gas discharged into the ash hopper 3 will flow upward. When the dust-containing flue gas discharged into the ash hopper 3 flows upward, the flat filter bag 12 will block and filter the dust-containing flue gas, so as to realize the function of filtering and removing dust from the dust-containing flue gas.
[0028] Meanwhile, when the flat filter bag 12 blocks and filters the dusty flue gas, the filtered dust impurities will gradually accumulate and stay at the bottom of the flat filter bag 12. When it is necessary to clean the flat filter bag 12, the compressed gas inside the gas storage tank 14 is discharged into the inside of the outlet pipe 16 along the air outlet 15 by controlling the opening of the blowing valve. When the compressed gas inside the gas storage tank 14 is discharged into the inside of the outlet pipe 16 along the air outlet 15, the compressed gas is sprayed downward through the nozzle 17. When the compressed gas is sprayed downward, the dust impurities accumulated and staying at the bottom of the flat filter bag 12 will be blown and fall into the inner bottom of the ash hopper 3. At the same time, when the nozzle 17 sprays the compressed gas downward, the driving motor 18 is controlled to be turned on. When the driving motor 18 is turned on, it will drive the first synchronous wheel 19 to rotate. When the first synchronous wheel 19 rotates, it will drive the second synchronous wheel 20 to rotate through the synchronous belt drive. When the second synchronous wheel 20 rotates, it will drive the outlet pipe 16 to rotate. When the outlet pipe 16 rotates, it will drive the nozzle 17 to swing. When the nozzle 17 swings, it will swing and spray the compressed gas downward to the upper end of the flat filter bag 12, so as to realize the blowing and cleaning of the flat filter bag 12 and facilitate the uniform swinging and spraying of the compressed gas to the upper end of the flat filter bag 12 for cleaning;
[0029] Meanwhile, when it is necessary to clean the dust impurities collected at the inner bottom of the ash hopper 3, the opening at the bottom of the ash discharge trough 4 is opened by opening the sealed bottom cover 5. When the opening at the bottom of the ash discharge trough 4 is opened, the rotating motor 6 is controlled to be turned on. When the rotating motor 6 is turned on, it will drive the transmission long shaft 7 to rotate. When the transmission long shaft 7 rotates, it will drive the ash discharge blade 8 to rotate. When the ash discharge blade 8 rotates, it will slap and discharge the dust impurities collected at the inner bottom of the ash hopper 3, so as to facilitate the downward slapping and discharging of the dust impurities collected at the inner bottom of the ash hopper 3 and avoid the situation that the dust impurities are piled up and blocked at the inner bottom of the ash hopper 3 and difficult to clean when being discharged.
