The invention provides a forging and pressing production system. The forging and pressing production system comprises a control platform, hot melting equipment, forging equipment and carrying equipment. At least one material is heated by the hot melting equipment, so that the material is heated to certain temperature. The forging equipment is controlled by the control platform to exert pressure tothe heated material, and then the material is forge-pressed and formed. The carrying equipment is controlled by the control platform to carry the material to circulate between the hot melting equipment and the forging equipment.

The invention relates to the technical field of fluorine chemical engineering and particularly relates to an operation method of a washing and absorbing device for preparing electronic-grade hydrogenfluoride. The method is characterized in that tail gas is fed through a gas feeding duct, with the temperature of the tail gas at this time being 19-21 DEG C; the tail gas flows upward through a filler and a liquid distributing grid tray in the washing and absorbing column and is subjected to mass and heat transfer with a hydrofluoric acid condensate sprayed by a spraying pipe member; the cooled tail gas enters a tail gas inlet of a condensation column through a gas discharging duct, is subjected to heat transfer with a condensation tube plate, then passes through a liquid removing device andis discharged through a tail gas discharging port; the temperature of the tail gas discharging port is controlled to be 9-10 DEG C; the hydrofluoric acid condensate condensed in the washing and absorbing column is gathered by the filler, and flows through a liquid collection tube along the wall of the washing and absorbing column to a circulation storage tank; the hydrofluoric acid condensate condensed in the condensation column flows to the circulation storage tank through a condensate outlet; and a circulation pump assembly allows the hydrofluoric acid condensate in the circulation storage tank to return to the spraying pipe member and to wash condensation tail gas.

The invention relates to the technical field of fluorine chemical engineering and particularly relates to a washing and absorbing device for preparing electronic-grade hydrogen fluoride. The device ischaracterized by including a washing and absorbing column, a circulating storage tank, a circulating pump assembly and a condensation column. The bottoms of the washing and absorbing column and the condensation column communicate with the circulation storage tank to form a U-shaped communicating vessel.

The invention relates to a self-adaption pipeline dredging robot. The self-adaption pipeline dredging robot comprises a shell, a reamer dredging mechanism, a camera and a plurality of traveling devices. The reamer dredging mechanism is arranged on the shell. The camera is arranged on the shell. Each traveling device comprises a variable diameter mechanism, a traveling mechanism and a pressure sensing module. The variable diameter mechanisms are arranged on the shell. The traveling mechanisms are arranged at the output ends of the corresponding variable diameter mechanisms. The pressure sensingmodules are matched with the corresponding lifting type variable diameter mechanisms. The self-adaption pipeline dredging robot has the beneficial effects that the robot is charged downward into a pipeline, and internal images of the pipeline can be acquired in real time so that working staff can know the environment of the robot conveniently and adjust the robot in time; data are monitored through the pressure sensing modules, the force condition and working conditions of the robot can be known conveniently, and the variable diameter mechanisms can be adjusted in time; thus, the robot can adapt to different pipeline diameters and can be stabilized in the most effective working condition all the time.
