Technical Field

[0001] The utility model belongs to the field of oily sludge treatment, in particular to oily sludge reduction equipment. Background Art

[0002] Oily sludge is an emulsified system composed of petroleum hydrocarbons, colloids, asphaltene, mud, sand, inorganic flocs, organic flocs, water and other organic and inorganic substances firmly bonded together. It is a hazardous waste. Residual activated sludge comes from the sewage biochemical treatment unit. It is an extremely complex inhomogeneous body composed of organic matter fragments, bacterial cells, inorganic particles and colloids. At present, the residual activated sludge generated by most petrochemical enterprises is still managed and disposed of as hazardous waste.

[0003] Oily sludge is mixed with a large amount of grease and water stains. When collected and processed, the grease and water stains will occupy a large volume, which is not convenient to transport together with the sludge. It needs to be reduced in size in advance. The existing sludge reduction treatment equipment has a high efficiency in separating oil, water and sludge, but it usually needs to be taken out and separated one by one, and the separation efficiency is low.

A feed pipe is fixedly provided on the upper part of the centrifugal drum, and the feed pipe is rotatably connected to the upper part of the tank body and passes through the tank body. A mud discharge pipe is fixedly provided at the lower part of the feed pipe, and the mud discharge pipe is rotatably connected to the lower part of the tank body and passes through the tank body.

[0006] Furthermore, the bracket is fixedly connected to the lower inner part of the tank body, a rotating groove is provided on the bracket, and the centrifugal drum is rotatably connected to the rotating groove.

[0007] Furthermore, the centrifugal drum is configured as a cylindrical filter screen structure.

[0008] Furthermore, the control mechanism includes a driving gear and a driven gear, a motor is provided on the upper part of the tank body, the driving gear is rotatably connected to the cavity and passes through the tank body, the driving gear is axially connected to the motor, the driven gear is rotatably connected to the cavity, the feed pipe is fixedly connected to the driven gear and passes through the driven gear, and the driven gear and the driving gear are meshingly connected.

[0009] Furthermore, a drainage pipe is provided at the lower part of the side of the tank body.

[0010] The beneficial effects achieved by the utility model using the above structure are as follows:

[0011] The oil sludge reduction equipment proposed in this scheme connects the feed pipe to the upper part of the centrifugal drum, connects the sludge discharge pipe to the lower part of the centrifugal drum, and uses a control mechanism to control the rotation of the centrifugal drum. There is no need to stop the separation work, and the oil sludge to be separated can be continuously added to the centrifugal drum through the feed pipe, with high separation efficiency.
