DETAILED DESCRIPTION

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] like Figure 1As shown, a bag dust collector pulse dust cleaning device in this embodiment includes a dust collecting box 5, and an air outlet pipe 3 is arranged in the dust collecting box 5, so that a part of the air outlet pipe 3 is arranged in the dust collecting box 5, and the other part is arranged outside the dust collecting box 5. The inlet of the air outlet pipe 3 is connected to the compressed air pipe 1 through an electromagnetic pulse valve 2. A first jet unit and two second jet units are arranged on the air outlet pipe 3, the first jet unit is arranged in the middle of an inner side wall of the dust collecting box 5, and the two second jet units are arranged on the other inner side wall of the dust collecting box 5, and the first jet unit and the second jet unit are arranged oppositely, and the second jet unit is arranged on the upper and lower sides of the first jet unit. A dust bag 4 is arranged in the dust collecting box 5, and the outlet of the first jet unit and the outlet of the second jet unit are respectively facing the dust bag 4. The electromagnetic pulse valve 2 pulses on and off the compressed air, and the compressed air is diverted to the first jet unit and the second jet unit through the air outlet pipe 3, and blown toward the dust bag 4. The dust attached to the wall of the dust bag 4 is repeatedly blown and shaken off by the compressed air blown out by the peripheral pulse.

[0016] like Figure 2 As shown, the first jet unit includes a first connecting pipe 6, and a first fixing seat 10 is fixedly arranged on an inner side wall of the dust collecting box 5, and the first connecting pipe 6 is fixed to the first fixing seat 10. The inlet of the first connecting pipe 6 is connected to the air outlet pipe 3 through the first interface 7, and the outlet of the first connecting pipe 6 serves as a first jet port 11, and the first jet port 11 faces downward and faces the dust collecting bag.

[0017] like Figure 3 As shown, the second jet unit includes a second connecting pipe 8, and a second fixing seat 12 is fixedly arranged on the other inner side wall of the dust collecting box 5, and the second connecting pipe 8 is fixed to the second fixing seat 12. The inlet of the second connecting pipe 8 is connected with the air outlet pipe 3 through the corresponding second interface 9, and the outlet of the second connecting pipe 8 serves as a second jet port 13, and the second jet port 13 faces downward and faces the dust collecting bag.

[0018] The above-mentioned air outlet pipe is made of PU material.

[0019] Three blowing points (the first jet port and two second jet ports) are arranged around the periphery of the nylon dust bag, divided into upper, middle and lower parts. A solenoid pulse valve (1 / 2" internal threaded pipe interface, one inlet and one outlet) is configured to connect compressed air (0.6-1MPa). The air source is arranged next to the electric control cabinet. The air inlet of the solenoid pulse valve is connected to the compressed air pipe, and the air outlet of the solenoid pulse valve is connected to the air outlet pipe to the dust collecting box.

The compressed air is blown out from three blowing points, and the dust attached to the wall of the nylon dust bag is repeatedly blown and shaken off by the compressed air blown out from the outer pulse. Through the strong spraying and vibration of high-pressure air pulses, the short fluff attached to the inner wall of the nylon mesh bag and the dust in the mesh are blown away and shaken off, which improves the dust cleaning effect and ensures the normal operation of the bag dust collector of the dust filtering equipment.

[0021] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
