Embodiment 1

[0031] like figure 1 and 2 As shown, embodiment 1 provides a kind of method for controlling electric spark oil fume, and it comprises the following steps:

[0032] Step S1, making a hexagonal prism rod by using a low-density porous material. Low density refers to 0.35-0.67g / cm 3 , the porous material is preferably charcoal, coke or machine-made charcoal, and the cross-section of the hexagonal prism rod is preferably a regular hexagon, and the hexagonal prism rod is used to make floating particles 1 .

[0033] Step S2, slicing the hexagonal prism bar material in step S1 to prepare floating particles 1, the floating particles 1 have a regular hexagonal sheet structure. The diameter of the circumscribed circle of the floating particle 1 is less than or equal to 5 / 18 of the diagonal length of the head section of the electric discharge machine tool, the diameter-thickness ratio of the circumscribed circle diameter and thickness of the floating particle 1 is 3-4, and the diameter...

Embodiment 2

[0044] like image 3 As shown, embodiment 2 provides a kind of floating particles for controlling electric spark oil fume. 3 The porous material is made of porous material, the porous material is preferably charcoal, coke or machine-made charcoal, the diameter-thickness ratio of the circumcircle diameter and thickness of the floating particles 1 is 3-4, and the preferred diameter-thickness ratio is 4.

[0045] The floating particles 1 provided in this embodiment are put into the processing fluid tank during use. When the floating particles 1 are in sufficient quantity, they will automatically cover the entire liquid surface under the action of buoyancy and tension.

[0046] Because the floating particle 1 is made of porous material, it has a large specific surface area and a well-developed pore structure, which is conducive to fully absorbing harmful soot substances. Especially the floating particles 1 made of charcoal or coke have a better effect of absorbing harmful oil fum...

Abstract

The invention discloses a method for treating electric spark lampblack. The method comprises the following steps: manufacturing a hexagonal prism bar by utilizing porosity material with density of 0.35 to 0.67g / cm<3>; slicing to prepare regular hexagon platy airborne particulates; quantitatively putting the airborne particulates in a processing liquid tank, wherein the airborne particulates are suspended on a liquid level; overspreading the suspended airborne particulates on the liquid level, and obstructing the bubbles rich in lampblack below the processing liquid level or adsorbing the samein the airborne particulates, wherein the lampblack cannot be diffused into the environment. The invention further discloses airborne particulates for treating the electric spark lampblack; each airborne particulate is a sheet with the section as a regular hexagon, and the density of the airborne particulate is made of the porosity material with density of 0.35 to 0.67g / cm<3>. Through the own adsorption of the airborne particulates, the lampblack absorption is more sufficient; an operation of singly arranging an exhaust fan and like mechanisms are unnecessary, and the noise pollution is avoided; the operations of adding an exhaust device for the equipment and maintaining and cleaning the exhaust device are unnecessary, and the cost of the complete machine and the running cost of the equipment are reduced.

Description

technical field [0001] The invention relates to the technical field of electrical discharge machining, in particular to a method and floating particles for controlling electric spark fume. Background technique [0002] EDM is a special processing method that utilizes the electric corrosion effect generated during the pulse discharge between the two poles immersed in the processing fluid to remove excess metal to meet the processing requirements for the size, shape and surface quality of the parts, also known as discharge processing. During spark discharge, under the action of heat source, bubbles are formed around the discharge channel rapidly. The bubbles are composed of metal vapor, processing fluid (mainly composed of kerosene) vapor and decomposed harmful gas. After the bubbles float to the surface of the processing fluid, they will gradually diffuse and float to the periphery and continue to expand. When the internal pressure of the bubbles is higher than the atmosphe...
