Abstract

The invention discloses a moisture desulfurization gypsum stable discharging and metering system which comprises a support, a material storage barrel is arranged on the support, the material storage barrel is provided with a feeding port and a discharging port, the material storage barrel is provided with at least one layer of vibration disc, the vibration disc comprises a grating disc, more than one vibrator is arranged on the grating disc, a vibration spring is arranged between the grating disc and the inner wall of the material storage barrel, and the vibration spring is connected with the vibration disc. A ring beam is arranged outside the storage barrel, a weighing sensor is arranged on the support below the ring beam, at least two discharging wheels are arranged above the discharging port, each discharging wheel comprises a wheel shaft, blades are arranged on the wheel shafts, a discharging driving motor is arranged on the wheel shafts, a discharging detection device is arranged at the discharging port and comprises a rotating shaft, and more than six detection blades are arranged on the rotating shaft. And a speed measurement sensor is arranged on the rotating shaft. The problem that in the prior art, a storage barrel cannot conduct stable discharging is solved.

Description

technical field [0001] The invention relates to a feeding system capable of effectively controlling the feeding speed, in particular to a stable feeding and metering system for large-moisture desulfurized gypsum. Background technique [0002] In the process of cement production, it is generally necessary to add desulfurized gypsum to the raw materials as a retarder for cement. Desulfurization gypsum is a by-product of using lime-limestone to recover sulfur dioxide in coal or oil flue gas, and the final desulfurization gypsum generally has a relatively high water content (water content is about 20%). Since desulfurized gypsum is a powder material with very high fineness and high water content, it is easy to shed or flush when discharging, especially when discharging from the storage tank, it is difficult to ensure the stability of the discharging, even if The storage tank is equipped with a belt-type quantitative feeder to control the unloading, but when the material is punc...
