Technical Field

The application relates to the field of sewage treatment, in particular to a treatment device for oily sewage.

Background

Along with the rapid development of the transportation industry, the discharge amount of oily sewage generated by the maintenance of garages and the maintenance of machine yards is increasing day by day, if the oily sewage is directly discharged into a sewage pipeline, not only can the water body be polluted, but also oil stains can be adhered to the pipe wall to influence the operation and the drainage capacity of the pipeline, and the maintenance and the cleaning of the pipeline are very difficult. Therefore, oily sewage generated in places such as garage maintenance and apron maintenance is generally pretreated by an oil separation tank before being discharged, so as to remove oil and fat substances contained in the sewage.

At present traditional oil interceptor utilizes the density difference of oil and water, makes the greasy dirt float to the top of sewage through the certain time that stews, through outlet pipe discharge lower floor sewage, the greasy dirt still remains in the pond, and after the greasy dirt accumulation in the pond was too much, need the manual work to clearly draw, get rid of the greasy dirt to the cell body. However, the method is easy to form oil vapor in the tank body, and potential safety hazards are generated when the upper cover of the tank body is opened.

Disclosure of Invention

In order to reduce the greasy dirt in the pond body, this application provides a processing apparatus of oily sewage.

The application provides a processing apparatus of oily sewage adopts following technical scheme:

the utility model provides a processing apparatus of oily sewage, includes the cell body, is located the guiding device of cell body and is located the oil tank of cell body, the cell body on peg graft and have the inlet tube of horizontal setting, the oil tank setting on the lateral wall of cell body and set up with the inlet tube is relative, the guiding device set up on the oil tank and be linked together with cell body and oil tank respectively, be provided with the outlet pipe that passes the cell body lateral wall on the guiding device, be provided with the overflow weir that makes the upper oil dirt in the oily sewage in the guiding device get into the oil tank in the guiding device.

Through adopting above-mentioned technical scheme, in oily sewage passed through the inlet tube entering pond, partial oily sewage got into the guiding device in, the upper greasy dirt of the oily aquatic in the guiding device passed through the overflow weir and got into the oil tank, and lower floor's sewage is blockked by the overflow weir and stays in the guiding device to outwards discharge through the outlet pipe. The guiding device that sets up, with the inside partial oily sewage water conservancy diversion of the internal portion of cell body to inside, reduced the oily sewage volume that contacts with the lateral wall of cell body to reduce the greasy dirt volume of adhesion in the cell body, also reduced the production of the interior oil steam of cell body, reduced the potential safety hazard.

Optionally, the flow guiding device comprises a body, and a water inlet is formed in the side wall of the body, which is close to the water inlet pipe;
