Described inner tube 2-2 is made of stainless steel, and its top is provided with screw thread, and nut, nut bottom are provided with screw thread
With outer tube 2-1 top surfaces overlap so that inner tube 2-2 can freely be moved up and down in outer tube 2-1, and not with outer tube 2-1 rotation and
Rotate, (inner tube and the connected mode of outer tube are also changed to connect by rolling bearing herein, can also realize above-mentioned function), inner tube
2-2 external diameter is 45mm, and distance of wall thickness 9mm, inner tube the 2-2 bottom away from the inner bottom surface of heat storage can 4 is 35mm, inner tube 2-2
Bottom is provided with 90 ° of bending, and the passage 2-3 of tube wall is provided through on tube wall, and passage 2-3 diameter is less than inner tube 2-
2 internal diameter, passage 2-3 are provided with 2 groups by axial symmetry of inner tube 2-2 axis, are provided with passage 2-3 and inner tube 2-
The vertical breather pipe 2-4 of 2 setting directions, said inner tube 2-2 tops port connect with the high pressure air rifle muzzle of nitrogen pot when in use
Connect.
The utility model is that bottom phase-change material solid state is stirred to realize by being passed through high pressure nitrogen into heat storage can 4
Mix, due to the characteristic of nitrogen in itself, it is not chemically reacted with phase-change material；Inner tube 2-2 is set by the nut on top
It is placed in outer tube 2-1, it is freely moved up and down in outer tube 2-1, and do not rotated with outer tube 2-1 rotation；In inner tube
2-2 bottom is provided with 90 ° of bending, and the tube wall surrounding of inner tube 2-2 bottoms is provided with passage 2-3, set in passage 2-3
The breather pipe 2-4 vertical with inner tube 2-2 setting directions is equipped with, the phase-change material solid state in all directions can be stirred,
Stirring efficiency is increased, improves mixing quality；And nitrogen tube 2 is directly installed on heat storage can by screw thread when in use
On 4 upper lid 3, convenient installation, and nitrogen tube 2 is not easy to be blocked by the phase-change material in heat storage can 4, easily maintenance and more
Change.
Air bleeding valve (non-label in figure) is additionally provided with upper lid 3, pressure gauge is provided with the air bleeding valve, when heat storage can 4
When interior pressure exceeds setting value, control air bleeding valve, which starts, excludes nitrogen in heat storage can 4, ensures the safety of equipment.
When in use, the high pressure gas muzzle of the upper port of nitrogen tube 2 and nitrogen is connected, high pressure air rifle is soft by high pressure
Pipe is connected with nitrogen pot, the outer tube 2-1 of nitrogen tube 2 is connected with the through hole that the upper center of lid 3 opens up, by outer tube 2-1 outer walls
The screw thread of setting realizes the regulation of nitrogen tube 2 in the longitudinal direction in heat storage can 4, makes its equal energy in certain depth bounds
Fully it is blown into high pressure nitrogen；In heat storage can 4 for heat accumulation phase-change material through phase transformation after a while and temperature change it
Bottom has partial phase change material solid and can not liquefied afterwards, now opens high pressure air rifle and is passed through high pressure nitrogen to the bottom of heat storage can 4,
The phase-change material solid state for being deposited in bottom is blown and floated by the air blast that high pressure nitrogen is formed, and carries out the liquid phase on itself and top
Become liquid after sufficiently combining.
Compared with other existing phase transformations go out hot systems, the utility model has following more obvious advantage：Equipment is simple, storage
The thermal efficiency is high, cost is low, heat accumulation process is more environmentally-friendly, can effectively realize hot transformation of energy, be applied widely.
Exemplary description is done to the utility model above, it should explanation, do not departing from core of the present utility model
In the case of the heart, any simple deformation, modification or other skilled in the art can not spend creative work etc.
The scope of protection of the utility model is each fallen within replacing.
