Detailed Description
The present invention will be further described with reference to the accompanying drawings.
1-3 metallographic test abrasive paper constant temperature and humidity drying system, take out wet case 301 and constant temperature and humidity case 302 including drying, drying takes out wet case 301 and carries out preliminary drying to abrasive paper to detach the moisture on the abrasive paper, constant temperature and humidity case 302 further dries the heat preservation to abrasive paper, and readjusts abrasive paper's humidity, prevents that abrasive paper's humidity from crossing excessively and causing easy the desiccation of abrasive paper. The arrangement of removing moisture firstly and then humidifying can better adjust the humidity of the finished sand paper and improve the quality of the finished sand paper.
The paper outlet of the drying and dehumidifying box 301 is communicated with the paper inlet of the constant temperature and humidity box 302, and the sandpaper passes through the drying and dehumidifying box 301 and then enters the constant temperature and humidity box 302. A drying heating pipe 303 for primarily drying the sandpaper, a dehumidifying fan 304 for removing moisture and waste gas generated by the drying and dehumidifying box 301, and a plurality of sandpaper turning rollers for adjusting the movement direction of the sandpaper are arranged in the drying and dehumidifying box 301. Be provided with in the constant temperature and humidity case 302 and carry out constant temperature heating pipe 305 that the secondary was dried to abrasive paper for adjust the atomizing humidifier 306 of the humidity of abrasive paper, and adjust a plurality of abrasive paper steering rolls of the direction of motion of abrasive paper. The box body shell of the constant temperature and humidity box 302 is provided with a hollow heat insulation layer 307, the hollow heat insulation layer 307 surrounds the inside of the constant temperature and humidity box 302 in a surrounding manner, the air outlet of the dehumidifying fan 304 is communicated with the air inlet of the hollow heat insulation layer 307, the air outlet of the hollow heat insulation layer 307 is communicated with the waste gas collecting device, the dehumidifying fan 304 extracts waste gas which is generated in the drying dehumidifying box 302 and conducts the waste gas into the hollow heat insulation layer 307, and the waste gas is discharged into the waste gas collecting device from the air outlet of the hollow heat insulation layer 307.
Constant temperature and humidity case 302 and stoving dehumidification case 301 are square cross-section's rectangular form box, the vertical setting of stoving dehumidification case 301, constant temperature and humidity case 302 level sets up. The upper end of the drying and dehumidifying box 301 is communicated with the horizontal end of the constant temperature and humidity box 302, and the whole body is in an L shape rotating ninety degrees.
The dehumidifying fan 304 is arranged at the upper end of the drying dehumidifying box 301, and because the upper end of the drying dehumidifying box 301 is communicated with one horizontal end of the constant temperature and humidity box 302, and the constant temperature and humidity box 302 can also generate waste gas in the process of drying and humidifying the sandpaper, the dehumidifying fan 304 can also extract the damp and hot waste gas in the constant temperature and humidity box 302 actually.
