The bottom of the bag-removing box 2 is provided with a lower jaw plate 21, and the top is provided with an upper jaw plate 22 which can be opened and closed relative to the box body; referring to fig. 3, one end of the upper jaw plate 22 is rotatably connected to the box body of the bag-removing box 2; the upper jaw plate 22 is also connected with a flap cylinder 25 for driving the upper jaw plate to open and close; a cutting knife assembly is arranged at the discharge port of the bag removing box 2;
the upper jaw plate 22 and the lower jaw plate 21 are respectively provided with an upper bayonet 23 and a lower bayonet 24 which are parallel to the conveying direction; further, the upper bayonet 23 is at least two groups, and the lower bayonet 24 is at least three groups. Preferably, the upper bayonet 23 of the present invention is in three groups and the lower bayonet 24 is in four groups.
In order to make the upper bayonet 23 cut the bag, it is preferable that the upper jaw plate 22 has an arc-shaped protrusion structure which fixes the upper bayonet 23;
the cement bag slides into the bag-removing box 2 at a certain speed, and then slides on the lower jaw plate 21 in an accelerating way, and then the cement bag is respectively slid out of the opening by the upper bayonet 23 and the lower bayonet 24, so that cement powder leaks out. And at the discharge port, the end part of the cement bag is cut by the cutting knife assembly. At this time, the vibration motor 31 is started, and the cement powder falls into the dropping hopper 300. Furthermore, the material collecting box 200 is provided with an air exhaust port, so that a certain negative pressure is generated in the box, and the dust is prevented from escaping from the bag removing box 2.

The windward plate is a Q235 steel plate and is welded on the inner wall of the inlet flue of the bag-type dust collector. The lower wall of the inlet flue of the bag-type dust collector is provided with a sewage discharge outlet, so that solid matters in the flue can be removed in time, and the residual solid matters are prevented from corroding the inner wall of the flue. Preferably, the horizontal distance from the welding position of the windward plate to the projection of the second spraying pipeline is 0-100 mm. Preferably, the included angle between the windward plate and the horizontal inlet flue is 30-90 degrees, so that the backflow of the smoke dust is blocked. Preferably, the solid powder adsorbent may be selected from lime and/or magnesium oxide.
The technical realization mechanism of the invention is that a first spray pipeline and a second spray pipeline are arranged at the inlet flue of the bag-type dust collector, and the water and the acidic substances in the low-temperature flue gas are absorbed by spraying the solid powder absorbent. The specific implementation process of the embodiment is as follows: when low-temperature flue gas containing moisture and acidic substances passes through an inlet flue of the bag-type dust collector, the first spraying pipeline and the second spraying pipeline are opened immediately to spray the solid powder absorbent, so that the solid powder absorbent is in full contact with the flue gas to be absorbed, and the solid absorbent absorbing the moisture and the acidic substances enters the bag-type dust collector along with the flow of the flue gas and then falls into the ash bucket. According to the invention, the spraying pipeline is arranged at the flue at the inlet of the bag-type dust remover, and the solid powder absorbent is sprayed to absorb the moisture and the acidic substances in the flue gas, so that the flue gas entering the bag-type dust remover has lower corrosivity and viscosity, and the dust removal efficiency and the service life of the bag-type dust remover are improved.
After the cement powder falls, the cutter cylinder 26 is started, and the upper jaw plate 22 is turned up and taken out of the waste bag.
Further, the upper and lower bayonet knives 23 and 24 each have a crescent-shaped puncturing tip, and the puncturing tips face the conveying direction; not only is beneficial to breaking and dismantling the bag, but also is beneficial to hooking out the waste bag.
Referring to fig. 4 again, the cutting knife assembly includes a cutting knife cylinder 26, a cutter seat 27 is fixed on the telescopic portion of the cutting knife cylinder 26, and a cutter head 28 is arranged on the cutter seat 27; further, the cutting head 28 has a triangular pyramid structure; is sharp and does not prevent the cement bag from being drawn back.
