Description

Technical Field

[0001] The utility model belongs to the technical field of drum dryers, and particularly relates to a water slag drying drum. Background Art

[0002] The water slag drying drum, also known as a drum dryer, is a drying device widely used in multiple industries. It is mainly used to process materials with high moisture content and large specific gravity, such as slag, limestone, clay, river sand, quartz sand, water slag, etc. It is a dryer for processing a large amount of materials, and realizes the drying of materials through processes such as heating, heat transfer, and mass transfer. It mainly consists of components such as a rotary cylinder, an air draft device, a high-speed dispersing device, lifting plates, a self-cleaning device, a transmission device, a conveying device, a hot air device, a speed reducer, a support device, and a sealing device.

[0003] For example, Chinese Patent with the publication number CN209944919U discloses a new type of drum dryer. In this new type of drum dryer, a roller is arranged inside the dryer body. A rotating shaft is fixed at the center of the rear sealing plate of the roller. The roller is driven to rotate and supported by the rotating shaft through a motor. In addition, the lower part of the roller is placed on supporting roller wheels. Both ends of the supporting roller wheels are arranged on the bottom plate inside the dryer body through roller bearings. The bottom sides of the roller are supported by the supporting roller wheels, so that the roller is more stable during operation and the drying efficiency is improved; multiple reinforcing ribs are arranged on the inner side surface of the roller, and the arrangement of the reinforcing ribs increases the strength of the roller, making the dryer more stable during operation.

[0004] The above patent has the following problems:

[0005] There are some disadvantages when using this patent. For example, when the above drum dryer dries wet water slag, some wet water slag will accumulate together. The simple rotation of the drum cannot disperse the accumulated water slag, which affects the drying speed. Moreover, when the wet water slag has a large viscosity, the wet water slag will adhere to the inner wall of the roller, resulting in the blockage of the heat dissipation holes. In view of this, we propose a water slag drying drum. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a water slag drying drum to solve the problems raised in the above background art.

[0007] In view of this, the utility model provides a water slag drying drum, including:

One ends of the plurality of sliders are respectively fixedly connected with a plurality of scraping plates, and the plurality of scraping plates are attached to the inner wall of the roller in the drying drum.

[0011] Based on the above structure, through the arranged annular groove and toothed ring, it is ensured that the toothed ring can rotate in the annular groove. Through the arranged driving component, it is ensured that the user can drive the toothed ring to rotate in the annular groove through the driving component. Through the arranged first fixing rod and the dispersing rod, it is ensured that when the toothed ring rotates, the toothed ring can drive the dispersing rod to rotate through the first fixing rod, so that the dispersing rod can disperse the accumulated water slag. Through the arranged chute, slider, tension spring and scraping plate, it is ensured that the plurality of sliders can be respectively affected by the pulling force of the plurality of tension springs, driving the scraping plates to always be attached to the inner wall of the roller of the drying drum. Through the arranged second fixing rod, it is ensured that when the first fixing rod rotates, the first fixing rod can drive the plurality of scraping plates to rotate through the plurality of second fixing rods, so that the plurality of scraping plates can scrape off the water slag attached to the inner wall of the roller of the drying drum.

[0012] In the above technical solution, further, the driving component includes:

[0013] A rotating groove, which is opened on the inner wall of the annular groove. A gear meshing with the toothed ring is rotatably connected in the rotating groove;

[0014] A through groove, which is opened between the drying drum and the fixed frame and communicates with the outside. A first sprocket is rotatably connected in the through groove, and one end of the first sprocket penetrates through the inner wall of the through groove and extends into the rotating groove to be fixed to the gear;

[0015] A motor, which is fixedly connected to one side of the drying drum. A second sprocket is fixedly connected to the output shaft of the motor, and a chain is meshed between the second sprocket and the first sprocket.
