Rolling drum dryer internally provided with toothed rolling wheels for treating molding sand

Abstract

The invention discloses a rolling drum dryer internally provided with toothed rolling wheels for treating molding sand. The rolling drum dryer comprises the plurality of rolling wheels, a plurality of rolling drums, two conveying rollers, a conveying belt, a huge hopper body and a connecting section, wherein bulged racks are arranged on the surface of each rolling wheel obliquely and spirally, and rotate for 180 degrees from one end of the corresponding rolling wheel to the other end of the corresponding rolling wheel; every two rolling wheels are arranged in the corresponding rolling drum; the bulged racks are arranged on the surface of each rolling wheel; the bulged racks on the surfaces of every two rolling wheels in the same rolling drum are engaged with each other, and the rolling wheels rotate oppositely; a through hole through which a central line penetrates is formed inside each rolling wheel; a forward extension section extending forwards is arranged at the lower end of the connecting section. The rolling drum dryer has the advantages that the rolling drums are simple in structure; the drying efficiency is high; the rolling drum dryer is efficient and uniform in drying, and low in energy consumption.

Description

technical field [0001] The invention relates to a drum drier equipped with toothed rollers for processing molding sand, in particular to a drier with two toothed rollers rolling and meshing with each other in the center of the drum, which belongs to the field of machinery. Background technique [0002] Drum dryer is widely used in chemical industry, brewing, manufacturing, pharmaceutical, fertilizer, municipal sludge treatment, etc. [0003] Drum dryer (also known as drum dryer, rotary dryer, etc.) is a contact type internal heating conduction drying machine. During the drying process, the heat is transferred from the inner wall of the drum to the outer wall, passing through the dried food materials attached to the outer wall of the drum, and evaporating the water on the materials. It is a continuous drying production machine. [0004] The drum of the drum dryer is a slightly inclined and rotatable cylinder. The wet material enters from the upper part of one end, and the dr...

AI Technical Summary

Problems solved by technology

[0007] 1. Driving the drum to rotate through the transmission structure requires a large amount of industrial electricity consumption, which is a waste of electricity, which does not conform to the concept of environmental protection and energy saving. At the same time, it is also a waste of resources and funds for users;

[0008] 2. The materials to be dried are scattered in the drum and turned over in the drum following the rotation of the drum, which may easily cause partial drying and uneven drying;

[0009] 3. There is a crushing device for the material to be dried inside the drum, the internal structure is complex, and it is difficult to maintain after being damaged;

[0010] Because the drum has to withstand the impact of the material to be dried, the ability of the drum to withstand the impact must be strong enough, so the quality of the drum is high, and the production cost and materials are high. After increasing the material cost, the quality of the drum will increase. Increase the power consumption of the drum and increase the power used
