Application of ultrasonic cleaning machine in fastener hot galvanizing intelligent production line system

Abstract

The invention discloses an application process in the technical field of fastener hot galvanizing intelligent production. The application process comprises the following steps that spraying cleaning is conducted, specifically, a high-pressure pump is used for circularly spraying cleaning liquid to the surface of a fastener, and dust and the like on the surface of the fastener are flushed off; ultrasonic cleaning is conducted, specifically, the fastener reaches an ultrasonic cleaning station along with a crawler belt and is immersed in cleaning liquid, and an ultrasonic generator impacts the surface of the fastener through mechanical vibration with high ultrasonic cavitation seepage force and is combined with the decontamination effect of a cleaning agent to clean away oil stains on the surface of the fastener; slitting 1, high-pressure air is used for purging the surface of the fastener, so that liquid on the surface falls back into a groove, and the situation that the liquid is brought into the next procedure to pollute working liquid is avoided; and water washing 1, wind shearing 2, water washing 2, wind shearing 3 and acid pickling are conducted, and finally discharging is conducted. According to the application process, the oil removal effect is good, the oil removal speed is high, the subsequent acid time and the acid consumption are reduced, the subsequent waste acid cleanliness is high, resource utilization is facilitated, the subsequent acid pickling speed is increased, equipment integration is achieved, the occupied area is small, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanizing intelligent production of fasteners, in particular to the application of an ultrasonic cleaning machine in an intelligent hot-dip galvanizing production line system for fasteners. Background technique [0002] Before the fasteners are hot-dip galvanized, the surface needs to be pre-treated to remove oil stains, rust stains and oxide scales on the surface. [0003] For the removal of oil stains on the surface of fasteners, the most commonly used method at present is soaking cleaning method, specifically, chemical cleaning in containers, such as lye, emulsifier liquid, organic solvent, compound degreasing agent, etc., immerse the fasteners In the liquid, the chemical agent reacts with the oil on the surface of the fastener to make it fall off and achieve the purpose of cleaning. Other processes are also used by some manufacturers, such as electrolytic degreasing, sandblasting degreasing...

AI Technical Summary

Problems solved by technology

[0004] 1. The degreasing time is long, even if the temperature rises, the general time is not less than 40 minutes, and the time increases with the increase of oil pollution

[0005] 2. The equipment occupies a large area. Due to the long working hours, the equipment is relatively large and occupies a large area.

[0006] 3. The degreasing is not complete, the oil stains after cleaning float on the liquid surface, and the surface is contaminated with dirty oil again during the process of lifting the fasteners out of the container

[0007] 4. There are potential safety hazards in electrolysis and high energy consumption

[0008] 5. Sandblasting air pollution is serious

[0009] 6. Pickling together with degreasing and oxide skin will reduce the pickling speed, and will also cause more oil in the pickling solution, which cannot be used as a resource.

[0010] 7. The cleaning is not in place, and the hard-to-clean places such as the internal corners of fasteners and trachoma are easy to be not cleaned properly

[0011] The missing plating rate is high, the surface cleaning is not in place or the oil is polluted twice, resulting in the surface cleanliness of the fasteners not up to standard, missing plating occurs, and the product quality is unstable
