This system saves costs while achieving good environmental protection.

[0027] The following section uses a bag-breaking and feeding system for packaged materials as an example to illustrate the entire technical process in detail.

[0028] Reference Figure 1 As shown, a bag-filled material breaking and feeding system includes a hopper 1 and a feed inlet 16. The feed inlet 16 is located at the top of the hopper 1 and is connected to the hopper 1. The system includes a bag breaking mechanism and a dust removal mechanism. The dust removal mechanism is located at the top of the hopper 1. The bag breaking mechanism includes a blade assembly and a screening grid 5. The blade assembly is located at the center of the feed inlet 16. The screening grid 5 is located at the bottom of the feed inlet 16 and is located on both sides of the blade assembly.

[0029] Reference Figure 1 and Figure 3 As shown, the blade 3 assembly includes multiple blade holder supports 2, multiple blade holders 15, and multiple blades 3. The bottom end of each blade holder support 2 is fixed to the side wall of the hopper 1, and the top ends of each blade holder support 2 are connected. The blade holder 15 is provided with a blade fixing hole 14. The blade holder 15 is fixed to the blade holder support 2 through the blade fixing hole 14, and the blade holders 15 are distributed in a circumferential shape at the top end of the blade holder support 2. The blade 3 is provided at the top end of the blade holder 15. The blade 3 is located at the center of the feed inlet 16, and the position of the blade 3 is lower than the feed inlet 16.

[0030] Continue to refer to Figure 1 and Figure 3 As shown, the blade 3 includes a beveled cutting edge 13, the outer side of the blade 3 is a beveled cutting edge 13, the top of the blade 3 is a pointed tip, and the bottom of the blade 3 is fixed to the handle 15.

[0031] The blade 3 has four blades in the hopper 1, and the blade holder 15 is provided with blade fixing holes 14. The blade holder 15 is fixed to the blade holder bracket 2 through the blade fixing holes 14 to facilitate maintenance and replacement.

[0032] The screening grid 5 is located at the bottom of the feed inlet 16, with one end connected to the hopper 1 and the other end connected to the cutter holder 2. Furthermore, the length of the screening grid 5 is greater than the width of the gap between the feed inlet 16 and the cutter holder 2, ensuring that the screening grid 5 can completely cover the gap.

[0033] Reference Figure 2 As shown, the dust removal mechanism includes a dust removal chamber 4, a dust removal pipe 12, a filter element 11, a dust removal fan 6, and a backflushing air mechanism. The dust removal fan 6 is located at the top of the dust removal chamber 4. The filter element 11 and the backflushing air mechanism are located inside the dust removal chamber 4. The backflushing air mechanism is located above the filter element 11. The dust removal pipe 12 is located at the bottom of the dust removal chamber 4. The dust removal pipe 12 extends from the top of the silo 1 and into the silo 1.

[0034] The backflush mechanism includes a backflush pulse valve 9, a backflush pipe 10, an air reservoir 8, and an oil-water separator 7. One end of the backflush pipe 10 is located above the filter element 11, and the other end of the backflush pipe 10 is connected to the air reservoir 8 through the backflush pulse valve 9. The oil-water separator is provided on the air reservoir 8.

[0035] Work process:

[0036] The bagged material is lifted by an overhead crane to the feed inlet 16 above the silo 1. With manual assistance, the ton bag is aligned with the feed inlet 16. The overhead crane slowly lowers the bagged material to the feed inlet 16, and the bottom of the bag is punctured by the blade 13 on the blade 3 for unloading. The screening grid 5 is set inside the silo 1 and located on the side of the blade 3 to prevent other objects from being mixed in with the material during unloading.

[0037] Dust generated during the feeding process is collected and recycled through the dust collection bin 4. The gas storage tank 8 stores gas through the oil-water separator 7. When the dust collection bin 4 is working, the dust collection fan 6 draws the dust into the dust collection bin 4 through the dust collection pipe 12. At this time, the gas discharged by the dust collection fan 6 after being filtered by the filter element 11 becomes clean gas. After feeding, the backflush pulse valve 9 intermittently backflushes the air pressure backflush to the filter element 11 through the backflush pipe 10, and then returns the material with dust to the silo 1 through the dust collection pipe 12.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
