BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for describing the embodiments. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. Among them:

[0014] Figure 1 It is a three-dimensional diagram of a preferred embodiment of a bag breaking bin of the present invention. DETAILED DESCRIPTION

[0015] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1 As shown, the embodiment of the utility model includes:

[0017] A bag breaking bin comprises a bag breaking bin body 1, a knife holder base 2, a knife holder 3 and a bag breaking knife 4.

[0018] The bag breaking bin body 1 is a hollow columnar structure for facilitating the placement of ton bags.

[0019] The outer wall of the bag breaking bin body 1 is provided with a plurality of bin body ear seats 5 distributed in an annular manner for easy lifting.

[0020] The top of the bag breaking bin body 1 is set as a circular opening and the bottom is set as a square opening. The circular opening design eliminates dust removal dead corners and improves dust removal efficiency.

[0021] The circular opening is a hollow composite structure and is tilted inward. A plurality of equally spaced dust removal holes 6 are arranged in a ring on the inner wall of the circular opening, and a dust collector docking port 7 is arranged on the outer wall. After the dust collector is connected, the air flow velocity around the top is higher than that in the middle area, thereby generating a pressure difference. When the bag is broken, the dust spreads upward from the bottom of the bag-breaking bin body 1 along the surrounding bin walls and is thereby absorbed.

[0022] The knife holder base 2 is in a cross-shaped structure and is horizontally fixed to the inner wall of the bag breaking bin body 1 to provide bottom support for the bag breaking knife 4.

[0023] A knife holder 3 is obliquely arranged on any of the knife holder bases 2 , and a bag breaking knife 4 is arranged on any of the knife holder bases 3 , and the tips of the four bag breaking knives 4 are above the center of the knife holder base 2 to facilitate bag breaking.

[0024] The bottom of the tool holder 3 is fixed or hinged to the tool holder base 2, depending on the needs.

[0025] Specifically, when the knife holder 3 is fixed on the knife holder base 2, it is used to provide a fixed bag breaking function.

[0026] When the knife holder 3 is hinged on the knife holder base 2, the knife holder base 2 is further provided with a cylinder (not shown in the drawings) to drive the knife holder 3 accordingly to provide movable bag breaking.

[0027] Working process: When the ton bag enters the bag-breaking silo 1, the ton bag is cut open by the bag-breaking knife 4 at the bottom, and the material is discharged from the bottom of the ton bag. Under the adsorption action of the dust collector, the dust spreads upward along the silo wall of the bag-breaking silo 1 and is absorbed by the dust removal holes 6 around the top of the silo wall.

[0028] To sum up, the bag breaking bin pointed out in the utility model can reduce the volume of the equipment and meet the needs of the renovation of old fly ash stabilization projects; it is easy to operate and can also stably remove dust; the bag breaking knife structure is flexible in design and can be optionally fixed or pneumatic, reducing labor intensity; the upper opening of the bag breaking bin adopts a circular design to eliminate dust removal dead corners and improve dust removal efficiency.

[0029] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
