Description

Technical Field

[0001] This utility model relates to the field of boiler equipment technology, and in particular to a gas purification device for boiler raw coal bunkers. Background Technology

[0002] A boiler coal bunker is a large container used to store the raw coal needed for boiler combustion. It is usually located near the boiler to facilitate the transport of the coal to the boiler for combustion. The design and construction of the coal bunker must take into account factors such as the amount of coal to be stored, the storage method, and the transportation method to ensure the normal operation of the boiler.

[0003] During the operation of a boiler's raw coal bunker, a large amount of dust-laden gas is generated. To reduce dust pollution to the environment and harm to human health, this dust-laden gas needs to be purified. Therefore, boiler raw coal bunkers are usually equipped with gas purification devices, such as bag filters, electrostatic precipitators, and cyclone dust collectors, to remove dust particles from the gas and meet environmental emission standards.

[0004] In existing technologies, some boiler raw coal bunker gas purification devices lack effective automatic cleaning and dust collection structures, resulting in short maintenance cycles. Frequent maintenance not only increases maintenance costs but also affects the normal operation of the boiler raw coal bunker, reduces production efficiency, and dust blockage can affect the stability of the entire device's operation. Once the filter components are blocked, gas flow is obstructed, affecting the purification effect of the entire device and even easily leading to device failure, increasing the risk of equipment operation. Therefore, a gas purification device for boiler raw coal bunkers is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a gas purification device for a boiler raw coal bunker, comprising a housing 1 and a housing 13. A cleaning and dust collection mechanism is fixedly connected inside housing 1, and a disassembly and assembly mechanism is fixedly connected inside housing 13. Housing 1, as part of the overall device, provides space for the cleaning and dust collection mechanism and other components. The disassembly and assembly mechanism, fixedly connected inside housing 13, is the location for secondary gas filtration, ensuring that the gas undergoes double-layer filtration, acting like a checkpoint to ensure that the final discharged gas is cleaner. A second exhaust fan 12 is fixedly connected to the left side of housing 1. When the exhaust fan 12 is turned on, it agitates the airflow, providing power for gas purification. The right side of housing 13 is fixedly connected to the left side of the exhaust fan 12. An air inlet pipe 24 is fixedly connected to the right side of housing 1, and an air inlet hood is fixedly connected to the bottom end of the air inlet pipe 24. The air inlet hood is used to transmit external gas into the purification device. An exhaust pipe is fixedly connected to the left side of housing 13, used to discharge the filtered and purified gas.

[0034] The cleaning and dust collection mechanism includes a dust filter plate 2, which is fixedly connected to the inner wall of the housing 1. The dust filter plate 2 is the first line of defense for purifying the gas, blocking dust and other impurities, and trapping dust in the gas on the surface of the dust filter plate 2, thus initially separating dust from the gas. An exhaust pipe 3 is fixedly connected to the top right side of the housing 1. An air nozzle 4 is fixedly connected to the output end of the exhaust pipe 3. An exhaust fan 5 is fixedly connected to the input end of the exhaust pipe 3. The bottom side of the exhaust fan 5 is fixedly connected to the top side of the housing 1. An air suction pipe 6 is fixedly connected to the left side of the exhaust fan 5. The external fixed connection is to the top left side of the housing 1. The bottom end of the suction pipe 6 is fixedly connected to the suction hood. The function of the suction hood is to expand the gas collection range and ensure that as much gas as possible after being filtered by the dust filter plate 2 is sucked into the suction pipe 6, thereby improving the gas collection efficiency. The gas extracted by the exhaust fan 5 reaches the jet head 4 through the exhaust pipe 3, ensuring that the jet head 4 has a stable air supply, thereby providing power for cleaning the dust filter plate 2. The gas sprayed by the jet head 4 can blow off the dust on the surface of the dust filter plate 2. The top inner wall of the housing 1 is fixedly connected to the electric slide rail 7. A sliding block 8 is slidably connected to the bottom of the slide rail 7. An electric motor 9 is fixedly connected to the left side of the sliding block 8. A cleaning brush 10 is fixedly connected to the drive end of the electric motor 9. The outside of the cleaning brush 10 is in contact with the outside of the dust filter plate 2. The electric slide rail 7 provides a track for the sliding block 8 to move. Driven by electricity, the sliding block 8 can move smoothly back and forth on its track. It is the key support structure for the back and forth movement of the cleaning brush 10. The electric motor 9 generates power to drive the cleaning brush 10 to rotate, providing the necessary power source for cleaning the dust filter plate 2. The cleaning brush 10 rotates under the drive of the electric motor 9. The dust on the surface of the dust filter plate 2 is swept off and works in conjunction with the gas sprayed from the jet nozzle 4 to complete the cleaning of the dust filter plate 2, ensuring the filtration effect of the dust filter plate 2. A dust collection box 11 is slidably connected to the inner wall of the housing 1. The top side of the dust collection box 11 is in contact with the bottom side of the dust filter plate 2. The main function of the dust collection box 11 is to collect the dust swept off the dust filter plate 2 by the cleaning brush 10 and blown off by the jet nozzle 4, to prevent the dust from spreading inside the housing 1 and to keep the inside of the housing 1 clean. The dust collection box 11 can be easily removed for cleaning, making the dust cleaning work more convenient.

[0035] Reference Figure 1 , Figure 2 and Figure 4The disassembly and assembly mechanism includes two fixing blocks 14, which are externally fixedly connected to the interior of the housing 13. Each fixing block 14 has an internal cavity, and a square plate 15 is slidably connected to the inner wall of the cavity. The fixing blocks 14, located inside the housing 13, provide space for the installation and movement of the square plate 15. Two transmission rods 16 are externally fixedly connected to the square plate 15, and their external surfaces are slidably connected to the interior of the fixing blocks 14. A locking block 17 is fixedly connected to the rear side of each transmission rod 16. A square groove 22 is formed on the rear side of the fixing block 14, and the outer wall of the locking block 17 is slidably connected to the inner wall of the square groove 22. Springs 18 are sleeved on the outside of each transmission rod 16, with their front sides fixedly connected to the front inner wall of the cavity, and their rear sides fixedly connected to the square groove 15. On the front side of plate 15, pull plates 19 are fixedly connected to the front sides of two transmission rods 16. The rear sides of the two pull plates 19 contact the front side of housing 13. Multiple guide frames 21 are fixedly connected inside housing 13. Filter plates 20 are slidably connected to the inner walls of two guide frames 21. Filter plates 20 are guided and installed by the guide frames 21. They are the core component for secondary gas filtration, further removing impurities from the gas, improving gas cleanliness, and ensuring that the final discharged gas meets requirements. The guide frames 21 provide guidance and sealing for the filter plates 20. A slot is provided at the bottom of the filter plates 20. The inner wall of the locking block 17 engages with the inner wall of the slot, providing a locking position for the locking block 17. Pulling the plate 19 releases the engagement between the locking block 17 and the slot inside the filter plate 20, making the disassembly of the filter plates 20 simpler and easier. During filter plate 20 installation, the pressure of the bottom of the filter plate 20 on the locking block 17 causes the square plate 15 to compress the spring 18, which stores energy. Once the filter plate 20 is fully installed, the spring 18 uses its own elasticity to push the locking block 17 back to its original position, so that it engages with the locking groove at the bottom of the filter plate 20, ensuring that the filter plate 20 is firmly installed. This is an important component that ensures the stable installation of the filter plate 20. The top of the housing 13 is provided with a top cover 23. When the filter plate 20 needs to be replaced, the top cover 23 must be opened to carry out the relevant operations. This is an important entry point for equipment maintenance, providing convenience for equipment maintenance.

[0036] Working principle: After prolonged use, the dust filter plate 2 is powered by the electric motor 9 to rotate the cleaning brush 10. The electric slide rail 7 drives the sliding block 8 to move back and forth. With the connection between the sliding block 8 and the electric motor 9, the cleaning brush 10 moves back and forth and rotates to clean the surface of the dust filter plate 2. At the same time, the exhaust fan 5 is turned on to generate power to stir the airflow. The gas filtered by the dust in the housing 1 passes through the suction hood and suction pipe 6 and enters the exhaust fan 5. Finally, the gas is sprayed out through the exhaust pipe 3 and the jet nozzle 4, blowing the dust on the surface of the dust filter plate 2 into the dust collection box 11. This achieves automatic dust collection and cleaning, reduces the maintenance cycle, separates dust and gas, and avoids clogging.

[0037] The exhaust fan 12 draws outside air into chamber 1 through the intake hood and intake pipe 24. After being filtered for dust, the air enters chamber 13, where it undergoes double-layer filtration using filter plates 20. Finally, the clean air is discharged through the exhaust port. When filter plates 20 need to be replaced or maintained, pulling the pull plate 19 in conjunction with the transmission rod 16 moves the locking block 17 forward, thereby releasing the locking block 17 from the groove inside the filter plate 20. Then, the top cover 23 is opened to remove the filter plate 20. At this time, the new filter plate 20 is slid down into the housing 13 by the guide frame 21. The bottom of the filter plate 20 will squeeze the locking block 17, causing the locking block 17 to slide into the square groove 22, which in turn drives the square plate 15 to squeeze the spring 18. When the filter plate 20 is completely slid into the housing 13, the locking block 17 loses the squeezing of the filter plate 20 and moves backward due to the pressure generated by the compression of the spring 18, and then engages with the locking groove at the bottom of the filter plate 20, thereby completing the installation of the filter plate 20.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
