The interior silo is mounted on the inside in compound storehouse.
1, the inner cylinder of the feed inlet end of the middle cylinder of the inner cylinder cylinder and compound storehouse of discharge port one end of interior silo connects solid It is set to one.
2, the external face deflector of the internal barrel of interior silo plays the role of the fixed interior silo of support and compound storehouse.Interior silo The feed inlet of discharge port and the middle silo in compound storehouse communicates.
3, the feed inlet of interior silo is the feed inlet of three dryness storehouses.
The helical blade is weldingly fixed on the inner cylinder cylinder inside interior silo, and helical blade is interior when can be to drying Material in silo storehouse is stirred, promotes, discharge.
1, the making material of helical blade is metal plate, and the thickness of helical blade is 1-3mm, and the height of helical blade is 150-300mm, the length of helical blade is depending on the length of interior silo.
2, layout of the helical blade on the inner cylinder cylinder in interior silo storehouse surround shape.
3, helical blade is fixedly welded on the inner cylinder cylinder inside interior silo；Helical blade plays the reinforcing rib of interior silo Effect, the helical blade being fixed on inner cylinder cylinder improves the compressive strength of the anti-negative pressure of inner cylinder cylinder.
The inner cylinder cylinder of the inside of described heat pipe one end and interior silo is connected to one, heat pipe arc surface One end is sufficiently fitted on the face of inner cylinder cylinder of interior silo.It will be in one end of heat pipe arc surface and interior silo by electric welding machine The inner cylinder cylinder in portion, which is welded and fixed, to be integrated.
1, the upper end of the heat pipe in interior silo is fixed with fixed strip, and fixed strip plays the role of fixed support heat pipe, avoids The junction of heat pipe and inner cylinder cylinder is caused a departure from because waving.
2, after the fixed fixed strip in heat pipe upper end is together in series, multiple heat pipes and the group that has been together in series is combined into an entirety, The heat pipe formed in this way just plays the role of reinforcing the anti-negative pressure of the inner cylinder cylinder of interior silo.
The compound storehouse and interior silo support fixing seal by deflector.
1, the height of deflector is the gap length between compound storehouse and interior silo.
2, the shape of spacing is flare shape between compound storehouse and interior silo, and the inner cylinder in compound storehouse and interior silo go out Material mouth end inner cylinder cylinder is fixed as one, and the spacing of the inner cylinder cylinder of compound storehouse and interior silo feed inlet end is progressive gets over Carry out bigger, such inside heat-conducting medium designed convenient for the inner cylinder in compound storehouse and the inner cylinder cylinder at inner cylinder bin discharge port external end It flows out.
3, the length of deflector is the length of the inner cylinder cylinder in compound storehouse.
The deflector is played the role of being to constrain heat-conducting medium to pass in and out space between compound storehouse and interior silo.
The space of the adjacent two deflector composition can be to avoid heat-conducting medium between compound storehouse and interior silo Inner end deposition do not flow.
If 1, being not provided with the space of deflector composition, inner end between compound storehouse and interior silo is like being not export Deep hole, the heat-conducting medium for releasing thermal energy of the inner end between compound storehouse and interior silo has no idea to flow out compound storehouse and inner cylinder Inner end between storehouse.Cause heat-conducting medium that can not be heated the heating of device again again in this way.
2, one end of the inner cylinder fixed closed of the middle silo of the inner cylinder cylinder and compound storehouse at inner cylinder bin discharge port external end is multiple Bottom end between He Cang and interior silo.
It 3, is not closed mouth between the inner cylinder of the middle silo of the inner cylinder cylinder and compound storehouse of interior silo feed inlet end, this A not closed mouth is exactly the space inlet and outlet of deflector composition, and heat-conducting medium is passed in and out from the inlet and outlet in the space that deflector forms Between compound storehouse and interior silo.
The caliber size of the feed inlet of the interior silo is smaller than the caliber size of the discharge port of interior silo, in compound storehouse The caliber size of the discharge port of the middle silo in the caliber size of the feed inlet of silo≤compound storehouse.
1, height of the height inside the inner cylinder cylinder at inner cylinder bin discharge port external than the inner cylinder cylinder at interior silo feed inlet It is high.
2, the external heat-conducting medium of internal barrel at inner cylinder bin discharge port external can be thermally conductive by the gravity of heat-conducting medium Inner cylinder cylinder of the medium flow field at interior silo feed inlet is spilt out.
3, the heat-conducting medium in the space of adjacent two deflectors composition with three dryness storehouses rotation when, work as water conservancy diversion Board group at space outlet when on the water level line of heat-conducting medium, deflector composition space below interior silo internal barrel Body is inner high outer low shape, and the heat-conducting medium in the space of deflector composition is constrained by the deflector of two sides, heat-conducting medium along The inner cylinder cylinder of interior silo, the inner cylinder cylinder through interior silo feed inlet end flow out fixed between the middle silo in compound storehouse and interior silo Deflector composition space.
With the rotation of three dryness storehouses, the space outlet of deflector composition led for heat-conducting medium in the heating cabinet When under the water level line of thermal medium, the heat-conducting medium in heating cabinet storehouse can flow into deflector between compound storehouse and interior silo and form Space.
The quantity of deflector between the compound storehouse and interior silo is 4-12.
1, adjacent deflector forms a space, and heat-conducting medium is in the space that adjacent deflector forms.
2, the thermally conductive of thermal energy is carried when the space of deflector composition is below water level line with the rotation of three dryness storehouses Medium flows into the space of deflector composition, carries inner cylinder of the heat-conducting medium of thermal energy by thermal energy conduction to compound storehouse, inner cylinder The inner cylinder cylinder in storehouse carries out thermally conductive heating, heat radiation heating.
It is the upper surface of deflector on the outside of longitudinal inner cylinder cylinder for being fixed on interior silo below the deflector On being supported on outside the inner cylinder in compound storehouse.
1, compound storehouse and interior silo are supported by deflector.
2, in the sealing space of the heat-conducting medium of heating cabinet deflector composition adjacent between compound storehouse and interior silo.
