Abstract
The utility model provides a reflow soldering waste gas discharge oil storage ware which characterized in that: comprises an air inlet pipe section, a connecting section, a gradual change section and an air outlet pipe section; the air inlet pipe section, the connecting section, the gradual change section and the air outlet pipe section are sequentially connected; the utility model discloses a rational design intake pipe section, the linkage segment, the gradual change section, the cross-sectional diameter of exhaust pipeline section, make scaling powder steam discharge when emiting into the linkage segment by the intake pipe section, because the increase of sectional area, the velocity of flow of steam reduces, set up the gradual change section that the cross-section becomes little from bottom to top simultaneously, make steam and the casing of oil reservoir carry out the efficient heat-conduction, the temperature of steam descends the condensation fast and becomes oily liquid drop, down flow into the oil storage tank along the inner wall of oil reservoir, the appearance that oily liquid drop instiled into PCB board problem has effectively been avoided, the quality of PCB board has been promoted.
Description
Technical Field
The utility model relates to an electronic circuit board processing field, in particular to reflow soldering exhaust emission oil conservator.
Background
During the operation of the reflow soldering machine, solder paste on a PCB (printed circuit board) is melted at a high temperature to generate Flux vapor of Flux, which is mainly composed of resin and rosin. The flux steam is cooled in the exhaust pipe to gradually form oily viscous liquid drops, and the oily viscous liquid drops flow back to the equipment furnace chamber along the inner wall of the exhaust pipe to drop to pollute the PCB surface, so that the PCB is degraded and even scrapped.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's problem, provide a reflow soldering exhaust emission oil storage ware, aim at solving the reflow soldering in-process and form the problem of gluing thick liquid drop drippage PCB face, promote PCB's quality.
The technical scheme of the utility model: the utility model provides a reflow soldering waste gas discharge oil storage ware which characterized in that: comprises an air inlet pipe section, a connecting section, a gradual change section and an air outlet pipe section; the air inlet pipe section, the connecting section, the gradual change section and the air outlet pipe section are sequentially connected; the air inlet pipe section penetrates into the inner cavity of the connecting section to be connected with the connecting section, and the outer wall of the air inlet pipe section, the inner wall of the connecting section and the bottom surface of the connecting section enclose an annular oil storage groove; the lower end of the air inlet pipe section is provided with an air inlet; the sectional area of the gradual change section is gradually reduced from bottom to top; a connecting flange is arranged on the air inlet pipe section; and an exhaust port is arranged at the upper end of the exhaust pipe section.
Further, the diameter of the section of the air inlet pipe section is smaller than that of the section of the connecting section; the diameter of the section of the upper end of the transition section is larger than that of the section of the air inlet pipe section; the diameter of the section of the exhaust pipe section is equal to the diameter of the section of the upper end of the transition section.
Furthermore, an oil discharge port is formed in the bottom surface of the annular oil storage groove and is connected with an external oil collecting container through an oil discharge pipe.
The utility model has the advantages that: (1) The utility model discloses a rational design intake pipe section, the linkage segment, the gradual change section, the cross-sectional diameter of exhaust pipe section, when making scaling powder steam discharge into the linkage segment by intake pipe section, because the increase of sectional area, the velocity of flow of steam reduces, set up the gradual change section that the cross-section diminishes from bottom to top simultaneously, make steam and the casing of oil reservoir carry out efficient heat-conduction, the temperature of steam drops down into the condensation oily liquid drop fast, flow into the oil storage tank along the inner wall of oil reservoir down, effectively avoided the oily liquid drop to drip into the appearance of PCB board problem, the quality of PCB board has been promoted; (2) The utility model discloses an oil conservator simple to use directly is connected the waste gas vent of oil conservator lower extreme and equipment, and the upper end is connected with former exhaust duct and can be used.
