Dust suppression funnel

Abstract

The invention discloses a dust suppression funnel. The dust suppression funnel comprises a hopper and a material distributor, wherein a discharge hole is formed in the lower end of the hopper; the longitudinal section of an opening in the upper end of the hopper is tapered; the material distributor is arranged in the hopper; the shape of the cross section of the hopper comprises a quadrangle; thehopper comprises a side wall inclining towards the middle part; the shape of the discharge hole is a polygon; the shape of the material distributor is matched with that of the discharge hole; the material distributor is mounted on the hopper through a slide mechanism; a chamfer used for increasing a distance between the material distributor and the side wall is arranged on the lower end surface ofthe material distributor; and a notch used for increasing a distance between the material distributor and the inner edge of the hopper is formed in the material distributor. The dust suppression funnel solves the mounting problem that the conical hopper difficultly adapts to a square counter hopper, greatly improves use stability, is more suitable for a plurality of occasions, and has wide applicability.

Description

Technical field [0001] The invention relates to the field of transportation equipment, in particular to a dust suppression funnel. Background technique [0002] In daily production, for the transportation and loading and unloading of granular materials, dust-free funnel devices are generally used to suppress the dust generated when bulk materials fall, protect the environment and reduce waste. The cross-sectional shape of the dust-free funnel in the prior art Generally round, the shape of the discharge port at the lower end of the funnel is also set to be circular. Generally, a ball valve or cone valve is set on the discharge port to control the speed of bulk material entering and leaving the funnel, but the conical funnel is not suitable for square In working environments such as container hoppers, the stability during use is reduced. Summary of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to...
