Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization gypsum processing, in particular to a material stabilizing device applied to desulfurization gypsum. Background Art

[0002] Desulfurized gypsum, also known as flue gas desulfurization gypsum, sulfur gypsum, or FGD gypsum, is primarily composed of calcium sulfate dihydrate (CaSO₄.2H₂O), the same as natural gypsum, with a content of ≥93%. Desulfurized gypsum is an industrial byproduct obtained from coal- or oil-fired industrial plants after sulfur dioxide is removed from flue gases. It is widely used in industries such as building materials. In particular, desulfurized gypsum is used in cement processing as an additive to sulfur trioxide, adjusting cement setting time and improving strength.

[0003] However, desulfurized gypsum tends to aggregate into lumps during transportation, especially when unloading from the feeding silo. This can easily cause blockage and sticking during use. Therefore, the feeding silo needs to be frequently unblocked, which results in frequent maintenance of the gypsum feeding silo, affecting production batching and, in turn, the quality of cement products. Utility Model Content

[0004] The purpose of the present application is to provide a material stabilizing device for desulfurized gypsum, so as to solve the problem that the existing material unloading method requires frequent dredging of the feeding bin, which makes the gypsum feeding bin frequently inspected and repaired, affecting the production batching.

[0005] To solve the above technical problems, the present application provides a material stabilizing device for desulfurized gypsum, comprising:

[0008] Based on the above embodiment, as a preferred implementation manner, the bulk plates are arranged in pairs, and a pair of the bulk plates are arranged at an angle.

[0009] What needs to be explained in detail in the solution is that the inner bottom of the material stabilizing box is also provided with an inclined material guide plate corresponding to the discharge pipe.

[0010] On the basis of the above embodiment, as a preferred implementation manner, the lower hopper is a trumpet-shaped lower hopper.

[0011] It should be further explained that the support legs and the material stabilizing box are integrally formed.

[0012] Based on the above embodiment, as a preferred implementation manner, the cross section of the horizontal rod is arranged in a fan shape.

[0013] Compared with the prior art, the utility model provides a material stabilizing device for desulfurization gypsum, comprising a material stabilizing box body supported and fixed by supporting legs, the top of the material stabilizing box body being connected to a lower hopper, and two gears meshing with each other being rotatably installed in the lower hopper. When in use, the desulfurization gypsum can be put into the lower hopper, and the desulfurization gypsum is crushed by the rotation of the gears and then enters the material stabilizing box body. A sieve plate is provided in the stabilizing box, and a telescopic rod is fixed at a relative position on the outside of the stabilizing box through a support plate. A horizontal rod extending into the stabilizing box is fixed at one end of the telescopic rod, and a bulk material plate is fixed on the lower side of the horizontal rod.

The telescopic rod is controlled to extend and retract through the horizontal plate to drive the bulk material plate to move back and forth along the sieve plate.
