Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, specifically a raw material premixing device for a slag remover used in steel casting. Background Technology

[0002] In the pre-mixing process of slag remover for steel casting, the mixing device refers to the equipment used to uniformly mix the various raw materials required for the slag remover according to a certain proportion and process requirements. The mixing device can uniformly mix the various raw materials of the slag remover together, ensuring that each raw material can give full play to its role and improve the overall performance of the slag remover. The mixing device plays a crucial role in the pre-mixing process of slag remover for steel casting. By reasonably selecting and designing the mixing device, the uniform mixing of raw materials and the production efficiency and product quality of the slag remover can be ensured.

[0003] Existing methods for mixing raw materials for slag removers typically involve simultaneously adding powdered and liquid raw materials to a mixing chamber. This approach lacks sufficient consideration of the characteristics of the raw materials. Powdered raw materials tend to agglomerate, while liquid raw materials are fluid. Direct mixing of the two can easily lead to uneven mixing, and some powdered raw materials may not be able to fully contact the liquid raw materials, thus affecting the performance of the slag remover. During the mixing process, a screen is used to filter impurities and agglomerates from the powdered raw materials, but after mixing, some raw materials often remain on the screen. These residues not only waste raw materials but may also affect the uniformity and consistency of subsequent batches. If only simple stirring is performed during the agitation process, the efficiency is often low, and the time required for the powdered and liquid raw materials to be fully mixed is long, which seriously reduces production efficiency.

[0004] Therefore, this utility model provides a raw material premixing device for slag removal agent used in steel casting to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0009] A stirring drum is located below the processing chamber. The inner cavity of the stirring drum is equipped with several reciprocating screws, which are fixedly connected by connecting cylinders. The outer ring of each reciprocating screw is threaded with a stirring ring. The inner cavity of the stirring ring is fixedly connected with several stirring blades in a ring shape. The processing chamber and the stirring drum are connected by several connecting pipes. A discharge pipe is fixedly connected to the bottom of the stirring drum.

[0010] As a preferred technical solution of this application, a T-shaped connecting block is fixedly connected to one side of the drive tooth plate, a fixing frame is fixedly connected to the bottom of the limiting frame, an electric telescopic rod is fixedly installed on the inner wall of one side of the fixing frame, and the output end of the electric telescopic rod is fixedly connected to one side of the adjacent T-shaped connecting block.

[0011] As a preferred technical solution of this application, the rotating gear and the drive gear plate mesh with each other through a locking tooth, and one side of the screen is rotatably connected to the inner wall of the adjacent processing chamber through a rotating shaft.

[0012] As a preferred technical solution of this application, a motor is fixedly installed on the top of the stirring drum, and the output shaft of the motor passes through the top of the stirring drum and is fixedly connected to one end of an adjacent reciprocating lead screw.

[0013] As a preferred technical solution of this application, several protrusions are fixedly connected to both sides of the stirring blade, and the outer surface of the stirring ring is in contact with the inner wall of the stirring cylinder.

[0015] As a preferred technical solution of this application, the processing chamber is fixedly connected to both sides of the support frame, and the bottom of the stirring cylinder is fixedly connected to several support legs.

[0016] (III) Beneficial Effects

[0017] The screen effectively disperses clumps of powdery raw materials, ensuring uniformity and consistency, and improving subsequent mixing. The drive plate and rotating gears rotate the screen, allowing residual powder to fall to the lower part of the processing chamber, preventing waste and increasing utilization. The reciprocating screw, connecting cylinder, stirring ring, and stirring blades provide multiple stirring forces within the mixing drum, enhancing mixing efficiency and uniformity. This ensures thorough and uniform mixing of the powdered and liquid raw materials of the slag remover, improving its quality stability and consistency, accelerating mixing time, and increasing production efficiency.

[0018] The design of the long plate, chute, and slider makes the displacement of the drive tooth plate more stable. The stirring blades further mix the liquid and powder materials inside the mixing drum. The stirring ring fits against the inner wall of the mixing drum, ensuring thorough mixing of the raw materials adhering to the inner wall and the materials inside the drum during displacement. The protrusions on the stirring blades increase the friction between the blades and the raw materials, reducing adhesion and thus minimizing mixing efficiency. The valve facilitates control over the outflow of the mixed materials. Attached Figure Description
