Description

Portable transfer station dust absorption environmental protection magazine attachment

Technical Field

The utility model relates to machinery and mechatronic field, in particular to portable transfer station dust absorption environmental protection hopper device.

Background

When bulk stockpiles, clinkers or grain materials are unloaded from a bulk stockpile goods yard or a wharf, the claw bucket can generate great dust when the materials are transferred to the hopper, and environmental pollution can be caused. Secondary dust can be generated when the materials are discharged from a discharge hole of the hopper. Because the pecking and grinding performance of bulk stockpiles, clinker or grain materials is extremely strong, the hopper needs to be subjected to anti-wear treatment.

The mechanism of dust generation: the bulk material pile, clinker or grain material can extrude the air at the bottom in the falling process, the pressure reaches the maximum after contacting the wall surface of the hopper, and the extruded air rapidly moves upwards when releasing the pressure because the hopper is a conical container with a discharge valve and an opening at the upper part at the lower part, thereby driving fine particles in the material to be entrained into the air to generate great dust.

The hoppers of the transfer stations in the prior art are generally provided with a series of control devices such as dust collectors and fans to control environmental indexes of dust discharged into air, so that the hoppers are called as environmental protection hoppers.
