The invention relates to oily sludge profile control equipment capable of realizing automatic feeding by using high-pressure hydraulic power and a working method of the oily sludge profile control equipment. The oily sludge profile control equipment comprises a feeder, a primary crushing device, a secondary crushing device, a crushing pump, a grinding machine and a tertiary crushing device which oily sludge enters sequentially, wherein the primary crushing device comprises a first storage tank, a grate is arranged at the tank bottom of the first storage tank, a screen is arranged on the grate, a plurality of holes are distributed in the screen, a first high-pressure pipeline is arranged on one side of the tank bottom inside the first storage tank and connected with a high-pressure water source, and a plurality of high-pressure nozzles are arranged on the first high-pressure pipeline. With the adoption of the oily sludge profile control equipment, the on-site high-pressure hydraulic power is fully utilized, through continuous impacting and crushing by high-pressure water, the feeding process of materials such as oily solid easy-to-cake waste and the like is realized, and in combination with equipment such as the crushing pump, the grinding machine and the like, the profile control injection process is realized finally. Operation is simple and convenient to implement, a large quantity of manpower and material resources are saved for profile control operation.
