The utility model discloses a finished product storage device for aluminum profile processing, which belongs to the technical field of aluminum profile production, processing and storage, and adopts the technical scheme that the finished product storage device comprises a shell, a plurality of groups of placing assemblies are arranged in the shell, and partition assemblies are arranged in the placing assemblies. The silica gel drying block can fully permeate into the placing box under the moisture absorption effect to continuously absorb moisture in the air, so that the aluminum profile placed in the placing box is prevented from being oxidized and rusted due to damp, and a dry and stable storage environment can be provided for the aluminum profile; and the separation assembly can quickly adjust the position of each separation plate according to the size of the aluminum profile, and ensures that the separation plates are stable and do not move in the using process, so that the aluminum profiles of different specifications can be accurately separated, disordered stacking is avoided, the efficiency of taking and placing the profiles by workers can be improved, and the practicability and reliability of the device are remarkably enhanced.

The application relates to a liquid rocket engine test heating device, in particular to a liquid rocket engine inner cavity induction heat accumulation type hot nitrogen gas supply device and method, and solves the technical problem that the existing low-temperature liquid rocket engine usually adopts an external hot air forced convection or electric heating wire heating nitrogen gas mode to heat the pipeline and the engine inner cavity nitrogen gas, and it is difficult to meet the low-temperature liquid rocket engine pipeline and engine inner cavity rapid temperature recovery requirement. The liquid rocket engine inner cavity induction heat accumulation type hot nitrogen gas supply device comprises a heating unit, a pressure monitoring unit, a temperature monitoring unit and a control unit; the heating unit comprises a buffer tank and a heating assembly arranged on the buffer tank; an air inlet of the buffer tank is used for being connected with an air source; the pressure monitoring unit and the temperature monitoring unit are arranged on the buffer tank and are connected with the control unit respectively; and the control unit is used for controlling the heating assembly to work according to the inner cavity nitrogen gas temperature and the outer wall temperature of the buffer tank.

The present application belongs to the technical field of metal manufacturing, and particularly relates to a steam treatment product cooling device and a cooling method thereof, which comprises an outer barrel, an inner barrel, a top cover, a flow guide air supply assembly and an adjustment space assembly; the inner barrel is arranged in the inner part of the outer barrel, and a chamber for accommodating a cooling medium is formed between the inner barrel and the outer barrel; the top cover is arranged on the top of the outer barrel; the present application is designed by means of double cooling and non-direct blowing air flow, specifically, the cooling medium between the outer barrel and the inner barrel is used to indirectly reduce the ambient temperature of the inner barrel, so as to reduce the temperature difference between the part and the cooling environment, avoid sudden cooling, and divide the cold air of the air blower into two paths by the flow guide air supply assembly; the spiral flow guide plate guides the air flow to surround the outer side of the part, the injection rod is directionally injected into the gap between the parts, and the injection inclined plate and the air gathering ring are used to realize full-dimension air flow coverage; the air flow is uniformly and gently contacted with the surface of the part, and there is no local air sharp cooling, so that the condensate water generation condition is eliminated from the root, and then the oxidation and rust are avoided.
