Annular air knife for cleaning inner wall of material container barrel

Abstract

The invention discloses an annular air knife for cleaning the inner wall of a material container barrel. The annular air knife is used for achieving the functions of dedusting and blow-drying the inner wall of an industrial barrel. The air knife is composed of an air jet head, an annular air knife and a connecting five-way joint, wherein the connecting five-way joint is used for connecting the air jet head and the annular air knife and providing compressed air for the air jet head and the annular air knife, the air jet head is used for dedusting and blow-drying the bottom of the barrel, and the annular air knife is used for dedusting and blow-drying the inner side of the barrel; and dust and water attached to the inner wall of the barrel can be gradually blown out from a hole by moving while blowing. The novel annular air knife has the advantages of being large in air outlet amount, uniform in air force and adjustable in air amount direction, and has great practical significance in cleaning work of the inner wall of the industrial barrel.

Description

technical field [0001] The invention relates to the water removal, dust removal and cleaning of the plane or cylindrical surface of industrial products, in particular to an annular air knife used for cleaning the inner wall of the material container barrel for dust removal and water removal inside the industrial barrel. Background technique [0002] The air knife includes strip air knife and annular air knife, which is a product specially designed to blow out strong and high-speed airflow to blow off dust, dry water stains, and cool down. [0003] Faced with the problems of blowing off dust and drying water stains on the inner wall of the barrel, traditional methods such as dryers are usually used at present. Traditional air blowing application products have many disadvantages, such as: the blown airflow is uneven; the compressed air consumption is very large; although it has a strong impact force, the noise level is too high, which seriously affects the health of on-site op...

AI Technical Summary

Problems solved by technology

Traditional air blowing application products have many disadvantages, such as: the blown airflow is uneven; the compressed air consumption is very large; although it has a strong impact force, the noise level is too high, which seriously affects the health of on-site operators; Blowing products often require frequent maintenance and have short service life; however, the air knife designed according to the Coanda effect ideally solves the above-mentioned several technical problems

[0004] The patented air knife (patent application number: 201410857746.4) designed a linear air knife, including two bodies, multiple air pipes and at least one first bracket. The problem of adjusting the angle with a knife; a patented adjustable annular air knife device (patent application number: 201510984737.6) provides an air knife with adjustable air volume and low air consumption. It has good adaptability, but the structure is relatively complicated ;Patented a circular air knife (patent application number: 201711105507.3) The air knife is designed in a circular shape, the direction is the periphery pointing to the center of the circle, and the circular welding strip inside the air ring is processed through the form of circular air outlet, ensuring Uniform stress; a patented circular air knife (patent application number: 201810781163.6) is also designed for the treatment of circular welding ribbons. The patent designs the air knife as a hollow round table, and the circular welding ribbon passes through the middle , the wind area is larger than that of the wind ring, and the wind force is more uniform

[0005] According to the existing patent query, all the air knives are straight or ring-shaped, and the direction of the air curtain is blowing from the outside to the center of the circle, which cannot be applied to the dust removal and drying of the inner wall of the barrel; in view of this situation, the present invention discloses a method for cleaning materials The annular air knife on the inner wall of the container barrel is specially designed for dust removal and drying on the inner wall of the barrel. The air knife can clean and dry the bottom of the barrel and the inner wall of the barrel in all directions without dead ends
