[0025] A pulse dust collector for cement preparation comprises a pulse dust collector housing 1, a pulse controller 4 and an air guide plate 10, a dust-containing gas inlet 2 is provided on the inner side of the pulse dust collector housing 1, a clean air outlet 3 is provided on the inner side of the pulse dust collector housing 1, an ash hopper 15 is fixedly connected to the bottom of the pulse dust collector housing 1, a dust outflow pipe 5 is slidably connected to the inner side of the ash hopper 15, a limit block 6 is fixedly connected to the outer side of the dust outflow pipe 5, a spring telescopic rod 7 is fixedly connected to the bottom of the limit block 6, a dust collecting box 8 is arranged on the outer side of the dust outflow pipe 5, a pressure gauge 9 is installed on the inner side of the dust collecting box 8, an alarm 16 is installed on the top of the dust collecting box 8, a filter bag frame placement rack 13 is fixedly connected to the inner side of the pulse dust collector housing 1, a filter bag frame 14 is arranged on the inner side of the filter bag frame placement rack 13, and a pulse device 12 is installed on the outer side of the pulse dust collector housing 1.

[0026] The spring telescopic rod 7 is arranged between the limit block 6 and the ash hopper 15, and the end of the spring telescopic rod 7 away from the limit block 6 is fixedly connected to the ash hopper 15. This arrangement allows the limit block 6 and the spring telescopic rod 7 to flexibly install the dust outflow pipe 5. When the dust collecting box 8 needs to be replaced, the dust outflow pipe 5 can be pushed upward. At this time, the dust outflow pipe 5 drives the limit block 6 to slide upward, and the limit block 6 and the ash hopper 15 stretch the spring telescopic rod 7, so that the dust collecting box 8 is easy to detach from the dust outflow pipe 5; the inner side of the ash hopper 15 is fixedly connected with a sealing gasket 11, which fits the dust outflow pipe 5. This arrangement enables the sealing gasket 11 to enhance the sealing between the dust outflow pipe 5 and the ash hopper 15, thereby reducing the occurrence of dust filling the air; the pulse device 12 includes a pulse valve 1201, a pulse tube 1202, a pulse nozzle 1203 and a compressed air storage bag 1204, and the compressed air storage bag 1204 is connected to the pulse valve 1201 The pulse valve 1201 is connected to the pulse tube 1202, the pulse tube 1202 is connected to the pulse nozzle 1203, and the pulse nozzle 1203 corresponds to the filter bag frame 14. This arrangement makes it possible for the pulse device 12 to start the pulse valve 1201 to open, and the pulse valve 1201 to extract the gas inside the compressed air storage bag 1204. The gas flows from the pulse tube 1202 to the pulse nozzle 1203, and the pulse nozzle 1203 sprays the gas in the direction of the filter bag frame placement rack 13. The gas acts on the filter bags inside the filter bag frame 14, and the filter bags inside the filter bag frame 14 will swell and vibrate due to the sudden pulse, thereby shaking off the dust attached to the filter bags inside the filter bag frame 14; there are five filter bag frames 14, and the filter bag frames 14 are evenly arranged on the inner side of the pulse dust collector housing 1. This arrangement allows the dust-containing gas to be filtered by the filter bags inside multiple filter bag frames 14, and finally can flow out of the pulse dust collector housing 1 from the clean gas outlet 3.

[0027] Working process: All electrical appliances in the utility model are equipped with an external power supply. When the pulse dust collector prepared by cement is used for dust reduction, the dust-containing gas enters the inner side of the pulse dust collector housing 1 from the dust-containing gas inlet 2. The air guide plate 10 inside the pulse dust collector housing 1 guides the dust-containing gas. After the action of the air guide plate 10, the heavier particles slide into the ash hopper 15, and then slide from the ash hopper 15 into the dust outflow pipe 5, and then slide from the dust outflow pipe 5 to the inner side of the dust collection box 8, and then act on the pressure gauge 9. The lighter particles adhere to the dust collector 8. On the filter bag inside the filter bag frame 14, the dust-containing gas passes through the filter bags inside the filter bag frame 14 for filtering, and finally flows out from the clean gas outlet 3. The pulse controller 4 outside the pulse dust collector housing 1 can control the pulse device 12 to start at a fixed time. The pulse device 12 starts to open the pulse valve 1201, and the pulse valve 1201 extracts the gas inside the compressed air storage bag 1204. The gas flows from the pulse tube 1202 to the pulse nozzle 1203, and the pulse nozzle 1203 sprays the gas in the direction of the filter bag frame placement frame 13. The gas acts on the filter The filter bag inside the bag frame 14 will swell and vibrate when subjected to a sudden pulse, thereby shaking off the dust attached to the filter bag inside the bag frame 14, and the shaken-off dust slides from the ash hopper 15 to the dust outflow pipe 5, and finally slides to the inside of the dust collection box 8. When the pressure gauge 9 detects that the weight of the dust inside the dust collection box 8 exceeds a preset range, the alarm 16 will light up to remind people around to replace the dust collection box 8, and the limit block 6 and the spring telescopic rod 7 flexibly secure the dust outflow pipe 5. When the dust collecting box 8 needs to be replaced, the dust outflow pipe 5 can be pushed upwards. At this time, the dust outflow pipe 5 drives the limit block 6 to slide upwards. The limit block 6 and the ash hopper 15 stretch the spring telescopic rod 7, so that the dust collecting box 8 is easy to detach from the dust outflow pipe 5, and the sealing gasket 11 enhances the sealing between the dust outflow pipe 5 and the ash hopper 15, reduces the occurrence of dust filling the air, and extends the service life of the dust outflow pipe 5 and the dust collecting box 8. The filter residue can be observed to determine whether it needs to be recycled.
