This application discloses a separation device for radioactive waste liquid. Each separation component has a connected separation chamber and a storage chamber. The separation chamber is used to contain separation resin, and the storage chamber is used to store eluent. A connecting member is correspondingly disposed on the separation component and located on one side of the storage chamber. The connecting member has a through-hole pressurization port. The pressurization component is detachably connected to the connecting member, and the pressurization component can deliver a pressure medium to the storage chamber through the pressurization port. In this application, the pressurization component in the separation device can output a pressure medium, which is transmitted to the storage chamber through the pressurization port to pressurize the eluent, effectively solving problems such as slowed rinsing and stagnation of rinsing, quickly obtaining the analytical solution to be analyzed after removing the radioactive matrix, and improving the analytical detection efficiency. At the same time, it avoids interference with operation by stirring, eliminates the possibility of introducing other contaminants due to stirring, and ensures the accuracy of detection of the analytical solution.

The utility model discloses a kind of mould locking pressurizing hydraulic circuit and die-casting machine, it is related to die-casting equipment technical field, including oil supply device, oil tank, pressurizing cylinder and mould locking cylinder;Pressurizing cylinder includes pressurizing oil inlet chamber, pressurizing oil return chamber and pressure building chamber;Oil supply device supplies oil to pressurizing oil inlet chamber and pressure building chamber, loop between pressurizing oil inlet chamber and pressure building chamber is equipped with first check valve;Pressure building chamber is communicated with mould locking cylinder rodless chamber;Pressurizing oil return chamber is communicated with oil tank, and oil passage between pressurizing oil return chamber and oil tank is equipped with first reversing valve;When the pressure of pressure building chamber reaches first pressure threshold, first reversing valve is powered to control the oil liquid of pressurizing oil return chamber flows into oil tank, so that the pressure of pressurizing oil inlet chamber is greater than the pressure of pressurizing oil return chamber, so that pressurizing piston rod is pressed into mould locking cylinder rodless chamber with the hydraulic oil of pressure building chamber.The scheme cancels accumulator, improves the pressure of mould locking cylinder under the precondition of not increasing system complexity and space requirement, can reduce cylinder diameter, reduce manufacturing and maintenance cost.
