Residual liquid emptier

Abstract

The invention provides a residual liquid emptier. The residual liquid emptier comprises an air blower, a residual liquid vaporizing chamber, a heater, a residual liquid collector, an outlet temperature measuring device, an emptying tube, an inlet temperature measuring device and a residual liquid inlet tube, wherein the residual liquid collector is arranged on the upper part of the residual liquid vaporizing chamber; the air blower is connected to the bottom of the residual liquid vaporizing chamber; the heater is arranged in the residual liquid vaporizing chamber and is connected with the residual liquid collector; the residual liquid inlet tube is connected with the residual liquid collector; the emptying tube is connected with the residual liquid vaporizing chamber; the inlet temperature measuring device is arranged at the connected part of the residual liquid inlet tube and the residual liquid collector; and the outlet temperature measuring device is arranged at the connected part of the emptying tube and the residual liquid vaporizing chamber. The residual liquid emptier can be used for vaporizing liquid nitrogen within a short time for effectively avoiding influence on environmental and personal injury or device damage caused by direct emission of the liquid nitrogen, and has the beneficial effects of high vaporizing efficiency, energy conservation and an extensive applicable range.

Description

Technical field [0001] The invention relates to the field of space ring mold testing, in particular to a residual liquid emptying device for a space ring mold testing liquid nitrogen process. Background technique [0002] At present, the heat sink of the space ring die equipment is provided by the liquid nitrogen system as the cold source. According to the heat load of the heat sink and the equipment situation, different forms of liquid nitrogen processes can be selected. The function of the liquid nitrogen process is to keep the heat sink at a temperature lower than 100K during the entire vacuum thermal test. It can provide enough cold for the heat sink and make the temperature of the heat sink uniform. Common liquid nitrogen processes include open boiling systems, pressure throttling systems, and one-way closed circulation systems. However, no matter what process is used, in order to ensure the stable operation of the system, the heat sink and equipment must always be pre-cool...
