Description

Oil-water separator's froth scraping device Technical Field The utility model relates to the technical field of oil-water separation, in particular to a foam scraping device of an oil-water separator. Background During the oil-water separation process, the separated oil droplets will generally float on the water surface. The existing oil-water separators have various problems when treating oil foam, such as low foam scraping efficiency, incapability of rapidly and effectively removing the oil foam on the water surface, and influence on the separation effect due to oil foam accumulation, and have the defects of complex structure, high installation and maintenance cost and inconvenience for large-scale application of part of foam scraping devices, and residual part of the oil foam in the separation liquid due to incomplete foam scraping of some foam scraping devices, so that the quality of oil-water separation is reduced. These problems are to be solved in order to improve the overall performance and the working efficiency of the oil-water separator. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a foam scraping device of an oil-water separator. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides an oil-water separator scrape foam device, includes separating tank, gyro wheel frame, scrape foam board and power device, the separating tank top is provided with the gyro wheel frame, install on the gyro wheel frame and scrape the foam board, the gyro wheel frame is fixed on the axostylus axostyle, the both ends of axostylus axostyle are fixed on the separating tank through the bearing, the bearing passes through the bearing frame to be fixed on the groove edge at separating tank top, one side end connection power device of axostylus axostyle, power device includes motor and transmission structure, the motor passes through transmission structure and connects the axostylus axostyle, provides power for the gyro wheel frame. The roller frame comprises a fixed frame, clamping plates and a fixed ring, wherein the fixed frame is a door-shaped fixed frame, two ends of the fixed frame are respectively fixed on the outer wall of the fixed ring, a plurality of groups of fixed frames are uniformly fixed on the outer wall of the fixed ring, the clamping plates are correspondingly arranged at the top of the fixed frame, foam scraping plates are arranged between the fixed frame and the clamping plates, a plurality of screws are uniformly arranged on the side wall of the top of the fixed frame, through holes are correspondingly formed in the foam scraping plates and the clamping plates which correspond to the screws, the foam scraping plates and the clamping plates are sleeved on the screws of the fixed clamps and are fixed through nuts, and the fixed ring of the roller frame is fixed on a shaft lever.
