DETAILED DESCRIPTION

[0017] In order to further expound the technical means and effects adopted by the present application to achieve the predetermined invention purpose, the specific embodiments, structure, features and effects according to the present application are described in detail as follows by combining with the drawings and preferred embodiments.

[0018] Embodiment: please refer to Figs. 1-2The dust removal device for adding additive premix includes a dust collecting mechanism 1 and a dust removal mechanism 2, the dust removal mechanism 2 is a pulse bag filter, the pulse bag filter has high purification efficiency and large gas treatment capacity. The dust collecting mechanism 1 is communicated with a mixer through a feeding port 3, and the dust collecting mechanism 1 is communicated with the dust removal mechanism 2 through a gas conveying pipe 4. The combination of the dust collecting mechanism 1 and the dust removal mechanism 2 enables the scattered feed raw materials and additives to be recycled and simultaneously dusted, thereby avoiding the pollution of the workshop environment. The dust collecting mechanism 1 includes a dust collecting box 5 and two dust filter screens 6, the dust collecting box 5 is divided into a first cavity 7 and a second cavity 8 by the dust filter screens 6, the first cavity 7 is communicated with the feeding port 3 of the dust collecting box 5, and the second cavity 8 is communicated with the gas conveying pipe 4. An induced draft fan 14 is installed on the gas conveying pipe 4. Under the action of the induced draft fan 14, when the feed raw materials and additives are premixed, the generated debris and dust are diffused from the mixer into the dust collecting box 5 through the feeding port 3, and then filtered in turn through the first cavity 7, the first-stage dust filter screen 6, the second-stage dust filter screen 6 and the second cavity 8, so that the scattered feed raw materials and additives can be recycled, and the materials will not be wasted.
