DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.

[0019] like Figure 1 to Figure 4 As shown, a material injection device with negative pressure feeding and dust removal includes a bracket 1, a silo 2 is arranged on the bracket 1, a feeding seat 3 is connected above the silo 2, a pulse dust collector 4 is installed above the feeding seat 3, the feeding seat 3 is connected to the silo 2, a vacuum pump 5 and a negative pressure feeding pipe 6 are connected to the feeding seat 3 through a connecting pipe, when the vacuum pump 5 is working, negative pressure is passed into the negative pressure feeding pipe 6, filling materials such as vermiculite, perlite, etc. are sucked from the outside, and the filling materials are sent into the silo 2, and a position meter 7 and a position meter 8 are respectively installed on the lower side of the silo 2.

[0020] In this embodiment, the capacity of the silo 2 is 5 cubic meters, the level meter 1 7 is located on the bottom side of the silo for material shortage alarm, and the level meter 2 8 is located on the upper side of the silo for raw material excess alarm.
