Embodiment 1

[0011] Example 1: Weigh 50g, 23g, 18g and 1000g of water respectively, mix tridecyl isomeric alcohol ether, coconut oil fatty acid acyldiethanolamine phosphate and polyoxyethylene oleate and stir evenly to obtain a grinding and cutting oil sludge cleaning solution; the above steps are obtained Mix 200mL of cleaning solution and appropriate amount of 303 stainless steel grinding and cutting sludge to prepare a slurry mixture with a solid content of 75%, place it in an ultrasonic disperser, and take out the mixture after ultrasonic dispersion for 10 minutes under mechanical stirring; the mixture obtained in the previous step Put it into a chip briquetting machine for briquetting, so that the metal shavings and the washing liquid are separated, and the metal shavings briquette separated from the oil is obtained.

Embodiment 2

[0012] Example 2: Weigh 50g, 23g, 18g and 1000g of water respectively, mix tridecyl isomeric alcohol ether, coconut oil fatty acid acyldiethanolamine phosphate and polyoxyethylene oleate and stir evenly to obtain a grinding and cutting oil sludge cleaning solution; the above steps are obtained Mix 200mL of the cleaning solution and an appropriate amount of 303 stainless steel grinding and cutting sludge to prepare a slurry mixture with a solid content of 40%, place it in an ultrasonic disperser, and take out the mixture after ultrasonic dispersion for 10 minutes under mechanical stirring; the mixture obtained in the previous step Put it into a chip briquetting machine for briquetting, so that the metal shavings and the washing liquid are separated, and the metal shavings briquette separated from the oil is obtained.

Embodiment 3

[0013] Example 3: Weigh 50g, 23g, 18g and 1000g of water respectively, mix tridecyl isomeric alcohol ether, coconut oil fatty acid acyldiethanolamine phosphate and polyoxyethylene oleate and stir evenly to obtain a grinding and cutting oil sludge cleaning solution; the above steps are obtained Mix 200mL of the cleaning solution and an appropriate amount of 303 stainless steel grinding and cutting sludge to prepare a slurry mixture with a solid content of 60%, place it in an ultrasonic disperser, and take out the mixture after ultrasonic dispersion for 10 minutes under mechanical stirring; the mixture obtained in the previous step Put it into a chip briquetting machine for briquetting, so that the metal shavings and the washing liquid are separated, and the metal shavings briquette separated from the oil is obtained.

Abstract

The invention provides a treatment method for grinding cutting oil sludge and belongs to the technical field of industrial solid waste comprehensive utilization. The novel treatment method for the grinding cutting oil sludge is provided so as to solve the problems existing during removal of the grinding cutting oil sludge through current treatment methods. According to the method, a proper surface active agent is selected and prepared into a cleaning solution with the proper concentration, and oil is separated from the surfaces of metal chips under the cleaning effect of the surface active agent. During actual operation, the cleaning solution and the grinding cutting oil sludge are mixed and prepared into paste with a certain solid content proportion; then ultrasonic cleaning is carried out; finally the cleaned grinding cutting oil sludge is put in a briquetting machine to be briquetted and dehydrated so as to remove the cleaning solution containing oil, and a metal chip compact briquetted block with extremely low oil content is obtained and can be conveniently conveyed and recycled to be put in a furnace.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of industrial solid waste. In particular, it relates to a processing method for grinding and cutting oil sludge. Background technique [0002] During the mechanical processing of metals (such as grinding, grinding, cutting), a large amount of metal shavings will be produced, and these metal shavings will be mixed with cutting oil, cutting fluid and waste mineral oil used in the processing to form grinding and cutting sludge . Due to the high oil content in this type of sludge, the reuse of metal scraps is hindered, and the effective utilization of metal scraps must be realized after the oil content therein must be effectively removed. The traditional treatment method is to remove the oil by burning, but in reality direct burning will produce a lot of thick smoke, and certain toxic substances will be produced when the burning is insufficient, causing pollution and damage to the ...
