Vibration air screen device applied to metal parts

Abstract

The invention is applicable to the technical field of screening devices, and provides a vibrating air screening device applied to metal parts, which comprises a shell, a vibrating screen barrel which is positioned in the shell, rotates automatically and vibrates up and down along the axis of the vibrating screen barrel, and a driving mechanism for driving the vibrating screen barrel to move; the vibrating screen barrel comprises an inner barrel and an outer barrel which are fixedly connected with each other; a plurality of sub storage spaces are uniformly distributed between the inner cylinder and the outer cylinder; the inner barrel is provided with a screen barrel inlet; a screen barrel outlet is formed in the outer barrel; a plurality of filter holes are formed in the outer wall of the outer cylinder, and bulges are arranged in the filter holes; a blowing nozzle is arranged on the outer wall of the outer cylinder; in this way, metal parts can be subjected to pile-dividing vibration treatment, the rust layer separation effect can be further promoted, and the rust layer separation efficiency is higher; centrifugal force generated by the vibrating screen barrel is matched with a vibrating effect to realize efficient separation of a rust layer; and during vibration, separated rust layers are blown out by utilizing airflow, so that the metal parts are treated more cleanly.

Description

technical field [0001] The invention relates to the field of screening devices, in particular to a vibrating air screen device applied to metal parts. Background technique [0002] Common metal parts include screws, bolts, nuts, etc. These parts are usually small in size. Common rust removal methods generally immerse these metal parts in a rust removal solution, and a chemical reaction occurs between the rust removal solution and the rust. To achieve the purpose of rust removal. [0003] However, when the rust of metal parts is serious, before chemical rust removal is used, it is necessary to use the physical method of vibrating screening to initially detach and screen out the easily separated rust layer on the surface of metal parts, so that the next chemical removal can be carried out. The rust effect is better (the same volume of rust removal liquid can remove rust on more metal parts), saving the rust removal liquid. [0004] The search patent number is CN202021613101....

AI Technical Summary

Problems solved by technology

[0004] The search patent number is CN202021613101.3, the name is a rust removal device for metal hardware, which discloses the use of a vibration motor to drive the rust removal cylinder to vibrate the metal parts placed in the rust removal cylinder, so that the metal parts Collide with each other, causing the rust layer to fall off

It has the following problems: 1. The vibration amplitude is not easy to control. When the vibration amplitude is too large, it is easy to cause parts to fall out of the derusting cylinder, and reducing the vibration amplitude will reduce the collision frequency between metal parts, resulting in Low rust removal efficiency

Second, the efficiency of rust layer peeling off only through the effect of vibration is not high

3. The fallen rust layer has not been screened out. After the work is completed, it is necessary to manually pick out the metal parts from the rust layer particles and clean them, which is inconvenient

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
