The application provides a four-cavity pressure simulation evaluation method with a capillary design kettle body, a platform and a wellbore. The kettle body is internally and externally provided with a tool pipe column, a packer rubber tube and a test casing, a capillary injection port is arranged on the upper end of the kettle body, and the capillary passes through the space between the test casing and the kettle body and is connected with the lower end of the test casing. The platform comprises the kettle body. The method is realized based on the kettle body. When the high-temperature and high-pressure downhole tool detection and evaluation is carried out, the strength of the test casing tooling is not additionally increased due to the limited structure, and the overall cost of the test is saved. After the four cavities are independently realized, the leakage of each cavity can be judged in the test process, and the test working condition of the downhole tool sample can be more accurately judged. The system pump injection pressurization efficiency is improved, and the detection precision and speed are improved. The internal cooling is realized at the same time as the pressure maintenance in the casing and outside the casing, and the interference on the test working condition during the cooling period is reduced.

The invention relates to an electric furnace rock wool production waste residue recycling system and method.The waste residue recycling system comprises a residue ball recycling line, a waste wool recycling line and a residue bin, and the residue bin is connected with a rock wool electric furnace through a discharging pipe; the slag ball recycling line is provided with a heavy slag feeding screw, the waste cotton recycling line is provided with a light slag feeding screw, and the heavy slag feeding screw and the light slag feeding screw are each provided with two discharging ports. The slag bin comprises an upper cylindrical bin body and a lower conical bin bottom, and the bottom of the bin bottom is connected with a discharge valve; an annular partition plate is arranged in the bin body and divides the bin body into an inner bin body and an outer bin body, two discharging ports of the heavy slag feeding screw and the light slag feeding screw are connected with the inner bin body and the outer bin body respectively, and each discharging port is provided with a valve. The volume occupied by light slag can be reduced, and the storage utilization rate is increased.

The utility model discloses an oil refining wastewater treatment device, which relates to the technical field of wastewater treatment, and comprises an air floatation tank, a bottom plate mechanism is arranged in the air floatation tank, a storage mechanism is arranged on the side surface of the air floatation tank, a moving mechanism is arranged on the rear surface of the air floatation tank, a scraper mechanism is arranged on the moving mechanism, and the scraper mechanism is arranged on the air floatation tank. The bottom plate mechanism is arranged to control the height of the bottom plate, if the liquid level of entering wastewater is lower than the bottom of the opening, the height of the bottom plate can be moved through the bottom plate mechanism, so that the liquid level of the wastewater is increased to be flush with the bottom of the opening, scum can be scraped into the storage box by the scraper, and the device can adapt to wastewater of various volumes; the device is further provided with a storage mechanism, when the scum in a storage box is too much, a pressing plate can descend to press the scum in the storage box, the occupied volume of the scum is reduced, the storage box can contain more scum, and the cleaning frequency of the scum in the storage box is reduced.
