Description

Technical Field

[0001] The utility model relates to the technical field of desulfurized gypsum dropping, in particular to a dropping anti-blocking device for a desulfurized gypsum hopper. Background Art

[0002] Desulfurized gypsum is also called flue gas desulfurized gypsum, sulfurized gypsum or FGD gypsum. Its main component is the same as natural gypsum, which is calcium sulfate dihydrate CaSO4.2H2O, with a content of ≥93%. Desulfurized gypsum is an industrial by-product gypsum obtained by coal-fired or oil-fired industrial enterprises after treating sulfur dioxide in flue gas. Its processing and utilization are of great significance. In the process of desulfurized gypsum feeding, a desulfurized gypsum hopper is used.

[0003] Most of the existing desulfurized gypsum hoppers are made into terraces or cones to form a discharge port that gathers in the middle, so that the desulfurized gypsum can be accurately dropped onto the conveyor belt and transported to the production line. However, desulfurized gypsum absorbs moisture and easily forms blocks. When the desulfurized gypsum hopper is used to drop the desulfurized gypsum, the desulfurized gypsum can easily be blocked at the discharge port at the bottom of the hopper, making it inconvenient for the desulfurized gypsum to be dropped smoothly.
