The application discloses a high-level solid waste super-pressure machine pressure head structure, which comprises a pressure head, a pressure rod, a connecting rod and an operating mechanism, the pressure rod is internally provided with an axial through hole, the connecting rod is arranged in the through hole of the pressure rod, a T-shaped head is arranged on the tail section of the connecting rod on the inner side of a shielding plate, the head section of the connecting rod on the outer side of the shielding plate is connected with the operating mechanism, a T-shaped slot hole is arranged on the pressure head, the operating mechanism can drive the connecting rod to rotate and adjust the relative angle between the double wings and the slot opening of the T-shaped head, so that the T-shaped head can enter or exit the T-shaped slot hole, and the operating mechanism can drive the connecting rod to axially move the T-shaped head, so that the T-shaped head can pull the pressure head to the pressure rod or push the pressure head to separate from the pressure rod. The pressure head structure is reasonable in structure, can be replaced at a long distance, is convenient to disassemble and replace, and can guarantee production efficiency. The application further provides a replacement method of the high-level solid waste super-pressure machine pressure head structure and a waste treatment equipment.

The invention belongs to the field of oil and gas exploitation, and discloses an annulus pressure-bearing tool and method for high-pressure-grade reverse circulation drilling and workover treatment, and the annulus pressure-bearing tool comprises a sealing assembly, a rotating assembly, a connecting piece and a fastening device; a traditional static sealing mode is changed into a mode that the sealing assembly and the rotating assembly are limited on the kelly bar body and move up and down along with the kelly bar, a kelly bar connector does not need to pass through the position of the sealing assembly all the time, abrasion of a sealing rubber core is reduced, the problem that the sealing rubber core is frequently damaged, punctured and leaked can be solved, and the service life of the sealing rubber core is prolonged. The active sealing mode can actively adjust the excitation pressure according to the sealing working pressure requirement and can supplement the pressure at any time, so that the sealing is more reliable; due to the arrangement of the rotating assembly, the pressure bearing capacity of the tool is further improved, the reliable annular dynamic sealing capacity under the higher pressure during reverse circulation drilling and grinding is guaranteed, the higher upward return flow speed of drilling and workover fluid in a drilling tool water hole and the higher drilling cutting carrying efficiency are provided, and the drilling and grinding time efficiency is improved.
