Description

Technical Field

[0001] This invention relates to the field of dry ash bulk loading machines for ash silos, specifically a dust collection device for dry ash bulk loading machines for ash silos. Background Technology

[0002] A dry ash bulk loading machine is a professional unloading equipment installed at the bottom of an ash silo. It connects to tank trucks through a liftable bulk loading head and uses a level gauge to automatically detect when the silo is full and stop loading. This allows for the efficient and sealed loading of dry fly ash into transport vehicles.

[0003] For a specific example of a dry ash bulk loading machine in an existing ash silo, please refer to a self-made dust collection device with application number CN202121459416.1. This device includes an exhaust duct for a pulverizing system, a main dust collection pipe on both sides of the exhaust duct, several branch dust collection pipes connected to a dust collection hood, a main dust collection ball valve on the main dust collection pipe, and dust collection ball valves on the branch dust collection pipes. This invention utilizes the negative pressure of the exhaust duct of an intermediate storage pulverizing system to provide sufficient suction, effectively collecting coal dust from the coal feeding area through the dust collection hood, branch dust collection pipes, and main dust collection pipe. The cleaning effect is excellent, effectively reducing secondary pollution, significantly reducing the labor intensity of employees, minimizing harm to the human body, protecting the physical and mental health of employees, and lowering labor costs.

A filter element 2 is inserted inside the left end of the exhaust pipe 28. 9. On the right side end, the exhaust pipe 28 is slidably connected to a filter element 29. Two sets of sealing rings 30 are fixedly connected to the outside of the filter element 29. The outside of the sealing rings 30 abuts against the inner wall of the exhaust pipe 28.

One end of the second return spring 34 is fixedly connected to the inner wall of the fixing block 31. The other end of the second return spring 34 is fixedly connected to one end of the pressing rod 32.The upper and lower ends of the outer side of the pressing rod 32 are also fixedly connected to one end of the positioning rod 37. The other end of the positioning rod 37 passes through the fixing block 31 and is inserted into the sleeve block 35. The positioning rod 37 is also slidably connected to the fixing block 31 and the sleeve block 35. The positioning rod 37 is a round rod design. The front and rear ends of the outer side of the filter element 29 are also fixedly connected to one end of the fixing frame 36.

The sleeve block 35 is inserted on the outside of the fixing block 31, and the sleeve block 35 is slidably connected to the fixing block 31. During operation, the motor 12 on top of the main body 1 of the device is started. When the motor 12 starts, it will drive the turbine 13 inside the outer body 10 of the fan to rotate. When the turbine 13 rotates, it will generate suction. Through the cooperation of the first connecting pipe 14, the telescopic pipe 15 and the second connecting pipe 16, the dust is sucked into the outer body 10 of the fan through the dust suction head 17. The barrier head 18 at the bottom of the dust suction head 17 can effectively prevent larger debris from being sucked in and causing blockage. Then the outer body 10 of the fan transports the dust into the collection box 25 through the third connecting pipe 24. When it is necessary to remove the dust from the collection box 25... At this time, simply rotate the sealing cover 27 to move it downwards along the outside of the discharge pipe 26 until it is completely detached. The dust inside the collection box 25 will then flow downwards through the discharge pipe 26. When the turbine 13 rotates, it simultaneously drives the fixed platform 19 to rotate. When the fixed platform 19 rotates, it will drive the scraper 22 to rotate and scrape along the inner wall of the blower outer body 10, thereby preventing dust from sticking to the inner wall of the blower outer body 10. When the scraper 22 becomes worn and thin, the first return spring 23 inside the first fixed sleeve 20 will automatically rebound, pushing the first moving rod 2. 1. Move upwards, so that the first moving rod 21 will always be in contact with the inner wall of the outer body 10 of the fan, and the gas inside the third connecting pipe 24 will be discharged outwards through the exhaust pipe 28. During the discharge process, it will be filtered by the filter element 29. When the filter element 29 needs to be removed, simply press the pressing plates 33 at both ends inwards at the same time. When the pressing plates 33 are pressed inwards, they will drive the pressing rod 32 to retract and move along the inside of the fixing block 31. At the same time, the pressing rod 32 will squeeze the second return spring 34 inside the fixing block 31 to retract and press... When the pressure rod 32 moves, it will drive the positioning rod 37 to move along the inside of the sleeve block 35 and the fixing block 31 until the positioning rod 37 is completely disengaged from the inside of the collection box 25. Then, the filter element 29 is pulled outward, which will drive the fixing frame 36 and the sleeve block 35 to move outward at the same time. The sleeve block 35 will also move outward along the outside of the fixing block 31 until it is completely disengaged. Similarly, when the filter element 29 moves outward, it will move outward along the inside of the exhaust pipe 28. When the filter element 29 moves, it will also drive the sealing ring 30 to move outward along the inside of the exhaust pipe 28 until it is disengaged. Example 2

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 10 As shown in the comparative embodiment 1, as another implementation of the present invention, the upper and lower ends of the outer side of the exhaust pipe 28 are also fixedly connected to the first fixing plate 38.

A third return spring 42 is provided inside the second fixing sleeve rod 39. One end of the third return spring 42 is fixedly connected to the inner wall of the second fixing sleeve rod 39, and the other end of the third return spring 42 is fixedly connected to the second moving rod 40. The front and rear ends of the outer side of the second moving rod 40 are also fixedly connected to one end of the guide limiting block 43. The second moving rod 40 is a circular rod design. The other end of the guide limiting block 43 is inserted into the inner wall of the second fixing sleeve rod 39, and the guide limiting block 43 is slidably connected to the second fixing sleeve rod 39. During operation, the positioning rod 37 disengages from the sleeve block 35, and the third return spring 42 inside the second fixed sleeve rod 39 will automatically rebound, pushing the second moving rod 40 inside the second fixed sleeve rod 39 to move outward against the second fixed plate 41. When the second fixed plate 41 moves outward, it will simultaneously push the filter element 29 outward to assist in disassembly. At the same time, when the second moving rod 40 moves, it will also drive the guide limit block 43 to move along the inner wall of the second fixed sleeve rod 39, which can prevent the second moving rod 40 from disengaging from the second fixed sleeve rod 39. The first fixed plate 38 and the second fixed plate 41 respectively fix and support the positions of the second fixed sleeve rod 39 and the second moving rod 40.
