Abstract

The invention discloses a bolt acid pickling device with a good closed waste gas collection effect. The device comprises an acid pickling tank, an acid pickling tank upper cover, a feeding rack, an acid pickling basket, an acid pickling basket moving device, a cross rod, an acid pickling basket hanging bracket, a control panel, an exhaust chimney and an exhaust fan. The acid pickling tank is a rectangular tank body, and the feeding rack is arranged at the transverse end in the long edge direction of the acid pickling tank. The acid pickling basket moving device is arranged at the upper end ofthe acid pickling tank, the acid pickling basket moving device drives the acid pickling basket and bolts in the acid pickling basket to transversely move in the long edge direction of the acid pickling tank back and forth and ascend and descend, and the acid pickling basket moving device drives the bolts to be subjected to acid pickling, washing and drainage automatically, so that the acid pickling efficiency is improved, the acid pickling quality is improved, the labor intensity of workers is reduced, the production cost is reduced, the sealing performance is good in the acid pickling process, waste gas generated in the acid pickling process can be collected and guided into waste gas treatment equipment, and the harm of the waste gas to the human body and the environment is reduced.

Description

【Technical field】

[0001] The invention relates to the technical field of fasteners, in particular to the technical field of bolt pickling equipment. 【Background technique】

[0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. In the bolt production process, in order to improve the anti-rust and anti-corrosion properties of the bolt surface, the surface of the bolt is often treated. Pickling is a method of bolt surface treatment. Pickling uses acid solution to remove scale and rust on the steel surface. The method is called pickling. It is a method of cleaning metal surfaces. Generally, the workpiece is immersed in an aqueous solution such as sulfuric a...
