Embodiment 1

[0053] The present invention "a safe, environment-friendly, zero-emission metal continuous degreasing method and device" provides a metal degreasing agent, the composition of the solvent (degreasing agent) includes: butane 65%, acetone 15%, butanone 20%; first add water (sealing liquid) of a certain height in tank body one, tank body five, then above-mentioned solvent is added to tank body three in the degreasing working area of ​​device of the present invention. The workpiece is a hanger basket equipped with a small mold, and the hanger basket is placed on the workpiece track 11 of the device of the present invention, and the device automatically degreases and regenerates. After degreasing, hang it down for use.

Embodiment 2

[0055] The present invention "a safe, environment-friendly, zero-emission metal continuous degreasing method and device" provides a metal degreasing agent, and the components of the solvent (degreasing agent) include: gasoline 60%, acetone 40%; first come first Add a certain height of saline solution (sealing solution) into tank body 1 and tank body 5, and then add the above-mentioned solvent to tank body 3 in the degreasing working area of ​​the device of the present invention. The workpiece is a hanger basket equipped with an oil screw, and the hanger basket is put into the workpiece track 11 of the device of the present invention, and the device automatically degreases and regenerates. After degreasing, hang it down for use.

Embodiment 3

[0057] The present invention "a safe, environment-friendly, zero-emission metal continuous degreasing method and device" provides a metal degreasing agent, and the components of the solvent (degreasing agent) include: solvent naphtha 65%, cyclohexanone 35%; First add a certain height of water (sealing liquid) into tank body tank body one and tank body five, and then add the above-mentioned degreasing agent to tank body three in the degreasing working area of ​​the device of the present invention. The tool is a hanger basket equipped with small hardware pieces to be electroplated. The hanger basket is put into the workpiece track 11 of the device of the present invention, and the device automatically degreases and regenerates. After degreasing, hang it down for use.

[0058] The invention can quickly remove grease and wax on the metal surface, whether it is vegetable oil, mineral oil or sintered oil formed at high temperature; whether it is grease or wax, whether it is light oi...

Abstract

The invention relates to a metal degreasing method and the field of degreasing, in particular to a safe, environment-friendly, zero-emission continuous metal degreasing method and device. The invention solves the key technical problem that the solvent is easy to volatilize to pollute the environment and endanger the health of workers during the traditional degreasing method; at the same time, it realizes the satisfaction of each workpiece (a section of a piece of work piece or a hanging piece in a hanging basket) Hanging workpiece) for the purpose of continuous degreasing. The structure of the invention makes the solvent and the workpiece sealed in the degreasing working area and the sealing liquid when the equipment is in working state, which prevents the poisonous and harmful gas in the degreasing agent from volatilizing and polluting the environment. The device of the present invention adopts a sealing scheme in which a sealing area is arranged before and after the degreasing work area. The sealing is only a relative sealing, and the sealing liquid is used for sealing. The effect of the sealing liquid is to seal the solvent vapor and not directly contact with the solvent. This avoids mutual contamination between the blocking liquid and the solvent; in addition, the blocking liquid communicates with the atmosphere, which avoids the danger of explosion due to excessive solvent vapor pressure in the device.

Description

technical field [0001] The invention relates to a metal degreasing method and the field of degreasing, in particular to a safe, environment-friendly, zero-emission continuous metal degreasing method and device. Background technique [0002] In the process of metal production and processing, such as: forming, cutting, grinding... and many other processing methods in the manufacturing process of metal products, lubricating oil, cutting oil... and many other oil products are often used. During the stay of metal parts between processes , It is also often used to isolate the workpiece from contact with oxygen, water vapor and salt in the air by immersion oil (anti-rust oil) to achieve the purpose of anti-corrosion. In order to ensure the quality of the next process (such as: passivation, oxidation, phosphating, electroplating, painting, etc.), there must be a cleaning and degreasing process. [0003] There are two main types of various metal degreasing agents commonly used at pr...
