Description

Technical Field

[0001] The present application relates to the technical field of cement production, and in particular to a feeding and proportioning device for desulfurized gypsum powder. Background Art

[0002] Cement is a powdery, hydraulic, inorganic cementitious material. After adding water and stirring, it becomes a slurry, which can harden in the air or in water, and can firmly bind materials such as sand and stone together. As an important cementitious material, cement is widely used in civil engineering, water conservancy, national defense and other projects. Cement clinker is made of limestone, clay and iron raw materials as the main raw materials, which are prepared into raw materials in appropriate proportions, burned until partially or completely melted, and cooled to obtain a semi-finished product.

[0003] At present, cement enterprises are the largest "slag-eating" industry and the main force in realizing circular economy of solid waste. Industrial by-product gypsum powder can be used as a cement retarder to replace natural gypsum for cement retardation. Limited by the characteristics of industrial by-product gypsum powder, it can replace a part of natural gypsum powder as a cement retarder. However, phosphogypsum powder has heavy water content. In actual production, the gypsum powder cannot be discharged smoothly and is prone to blockage. At the same time, high-temperature dried desulfurized gypsum powder is used as a cement retarder. High-temperature drying can cause the crystal water in the desulfurized gypsum powder to completely volatilize, making its crystal structure more stable and making the desulfurized gypsum powder easier to mix with other raw materials. This helps to reduce the release of crystal water and crystal changes that may occur in subsequent cement production, thereby improving the stability and reliability of cement after good proportioning. To this end, a feeding and proportioning device for desulfurized gypsum powder with anti-blocking and heating drying is proposed. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a feeding and proportioning device for desulfurized gypsum powder, which can solve the technical problem of feeding blockage in a desulfurized gypsum storage tank.

[0005] An embodiment of the present application provides a feeding and proportioning device for desulfurized gypsum powder, comprising a tank body, a feeding pipe is provided on the top of the tank body, a discharge pipe is provided at the bottom of the tank body, an anti-blocking component is rotatably provided in the middle of the tank body, a drying component is provided in the middle of the tank body, and a closing component is provided at the bottom of the tank body.

[0006] Furthermore, the anti-blocking component includes a first motor, a rotating rod, a plurality of breaking rods and a spiral blade. The rotating rod is rotatably arranged on the top of the tank body, the first motor is fixedly arranged on the top of the tank body, and the first motor drives the rotating rod to rotate.
