Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a cutting device for drying tough materials. Background Technology

[0002] In chemical equipment, the drying of tough materials, such as the drying of liquid materials by belt dryers, generally results in a loose solid material after drying. Although it may form large plates at the discharge end of the belt dryer, these plates are brittle and easily crushed by the blades and fall to the bottom of the discharge end, resulting in significant waste. However, sometimes the solid material after drying liquid materials may form hard plates that are difficult to cut by the blades, which can affect the normal operation of production. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a cutting device for drying tough materials, which can cut both loose and hard materials according to specifications, prevent waste, and ensure normal material feeding and normal production process.

[0004] The technical solution adopted in this utility model is:

[0005] A cutting device for drying tough materials includes a tough material dryer. A moving blade assembly and a fixed blade assembly are installed at the discharge end of the tough material dryer. The moving blade assembly includes a lifting power mechanism, a moving blade frame, and a moving blade. The moving blade is fixed on the moving blade frame, and the top of the moving blade frame is connected to and driven by the lifting power mechanism. The fixed blade assembly includes a fixed blade holder and a fixed blade. The fixed blade is fixed on the fixed blade holder, which is mounted on the body of the tough material dryer. The moving blade assembly and the fixed blade assembly slide together to cut the material discharged from the tough material dryer.

[0006] In the above technical solution, the tough material dryer is a belt dryer.

[0007] In the above technical solution, the lifting power mechanism of the moving knife assembly adopts a guillotine cylinder.

[0008] In the aforementioned technical application, the belt dryer adopts a multi-layer belt drying structure, and the corresponding moving blades and fixed blades are also multi-layered. The two ends of the multi-layered moving blades are fixed inside the moving blade frame, and the two ends of the multi-layered fixed blades are fixed inside the fixed blade holder.

[0009] In the above technical solution, the discharge end of the belt dryer is equipped with a sealing head, and the moving knife assembly and the fixed knife assembly are installed inside the sealing head.

[0010] In the above technical solution, the bottom of the end cap has a discharge port.

[0011] This invention features a moving blade assembly and a fixed blade assembly at the discharge end of a belt dryer. The fixed blade assembly is fixed to the cylinder at the discharge end of the dryer, and its fixed blade and the moving blade of the moving blade assembly form a scissor-like engagement. Based on the drying time of the material in the belt dryer, the time interval for the moving blades to cut is set in the program, such as once every 10 seconds. This causes the lumpy material to be cut off by the shearing force generated by the moving and fixed blades, and the material falls to the bottom of the dryer's discharge end. Because the newly designed fixed and moving blades of this invention work together to generate a very large shearing force with a small gap, there is no material deviation at the cutting point. Therefore, whether it is very brittle, loose slab material or hard, difficult-to-cut slab material, it can be cut cleanly and neatly, with no waste, and without affecting the normal production process.

[0016] Referring to the accompanying drawings, the present invention discloses a cutting device for drying tough materials, comprising a tough material dryer. A moving blade assembly and a fixed blade assembly are installed at the discharge end of the tough material dryer. The moving blade assembly includes a lifting power mechanism, a moving blade frame, and moving blades. The moving blades are fixed to the moving blade frame, and the top of the moving blade frame is connected to and driven by the lifting power mechanism. The fixed blade assembly includes a fixed blade holder and fixed blades. The fixed blades are fixed to the fixed blade holder, which is mounted on the body of the tough material dryer. The moving blade assembly and the fixed blade assembly slide together to shear the material discharged from the tough material dryer. The tough material dryer is a belt dryer, and the lifting power mechanism of the moving blade assembly is a guillotine cylinder. The belt dryer adopts a multi-layer belt drying structure, and correspondingly, the moving blades and fixed blades are also multi-layered. The two ends of the multi-layered moving blades are fixed to the inner side of the moving blade frame, and the two ends of the multi-layered fixed blades are fixed to the inner side of the fixed blade holder. A sealing head is installed at the discharge end of the belt dryer, and the moving blade assembly and the fixed blade assembly are installed inside the sealing head. The end cap has a discharge port at its bottom.

[0017] like Figure 1As shown, the belt dryer's track, driven by a track motor, moves towards the discharge end, conveying the dried material between the fixed blade assembly and the moving blade assembly. At set intervals, the moving blade, under the action of a cylinder, moves downwards to shear the dried material. The sheared material falls to the bottom of the dryer and is discharged via the discharge motor.
