Problems solved by technology

[0002] The main mineral of desulfurized gypsum is calcium sulfate dihydrate crystals. Different from natural gypsum, the particle size of desulfurized gypsum is relatively uniform. Natural gypsum is in the form of lumps bonded together. Desulfurized gypsum exists in separate crystal particles. Coarse particles after grinding are impurities, while fine particles after desulfurization are powdered. Desulfurization gypsum often contains impurities such as carbonate, silicon dioxide, magnesium oxide, aluminum oxide, and sodium oxide, and the impurities exceed a certain content. It will affect its quality, and in a humid environment, the phenomenon of "returning frost" will also occur. The existing desulfurized gypsum storage device only mixes desulfurized gypsum and stacks them together. During the stacking process, not only will the accumulated Soil pollution occurs in local areas and impurities often appear, frost return, etc. Therefore, the existing technology needs further improvement

Embodiment 1

[0025] like Figure 1-9The shown storage device for desulfurization gypsum includes a support 1, on which is arranged a silo 2 that can rotate along the transverse axis direction, the silo 2 is cylindrical and has a cavity structure inside, and the transverse axis is connected to the silo. The bottom surface is parallel, the storage bin 2 is divided into two closed cavities up and down by the elastic soft plate 3, the upper layer is the storage chamber 4, the lower layer is the filter chamber 5, and the bottom surface of the filter chamber 5 is provided with a first motor 7, the first motor 7. The output shaft is connected to the first hydraulic cylinder 6. The end of the telescopic rod of the first hydraulic cylinder 6 is connected to the first rotating rod 9 through the first fixing member 8. The length direction of the first rotating rod 9 is parallel to the bottom surface of the filter cavity 5. The rod 9 is also connected to the second fixing member 10, the lower end of t...

Abstract

The invention belongs to the technical field of desulfurized gypsum storage, and particularly relates to a desulfurized gypsum storage device which comprises a support, a storage bin capable of rotating in the transverse axis direction is arranged on the support, the interior of the storage bin is divided into an upper closed cavity and a lower closed cavity through an elastic soft plate, the upper layer is a storage cavity, and the lower layer is a filtering cavity. The end of a telescopic rod of the first hydraulic cylinder is connected with a first rotating rod through a first fixing piece, the length direction of the first rotating rod is parallel to the bottom face of the filtering cavity, the first rotating rod is further connected with a second fixing piece, the lower end of the second fixing piece is further connected with a second hydraulic cylinder, and the second hydraulic cylinder is connected with a cleaning head. According to the flue gas desulfurization gypsum storage device, powdery impurities of flue gas desulfurization gypsum can be conveniently discharged, and it can be guaranteed that the storage environment is dry.

Description

technical field [0001] The invention belongs to the technical field of desulfurization gypsum storage, and in particular relates to a desulfurization gypsum storage device. Background technique [0002] The main mineral of desulfurized gypsum is calcium sulfate dihydrate crystals. Unlike natural gypsum, the particle size of desulfurized gypsum is relatively average, while natural gypsum is in the form of lumps that are bonded together. Coarse particles after grinding are impurities, while fine particles after desulfurization are impurities, and desulfurization gypsum often contains carbonate, silicon dioxide, magnesium oxide, aluminum oxide, sodium oxide and other impurities, and the impurities exceed a certain content. It will affect its quality, and in a humid environment, the phenomenon of "returning frost" will also occur. The existing desulfurization gypsum storage device only mixes the desulfurization gypsum and stacks it together. Local soil pollution and impurities,...
