Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
It please refers to shown in Fig. 1-3, specific embodiment provided by the utility model is as follows:
A kind of cell negative electrode material powder transfer tank of the present embodiment, transfer tank tank mouth diameter is less than tank diameter, described
Tank body includes top half and lower half portion, the top half be folding structure (it is a kind of specifically, tank body top half
Bigbore telescopic bellows can be used), the bottom end of the top half is fixed with the sealing-plug for sealing the tank mouth
4.Tank mouth is clogged using sealing-plug 4 by way of folding top half, it, will after transfer tank and drying chamber complete sealing fastening
Sealing-plug 4 takes out from tank mouth, it is possible to reduce the contact area and time of material and air.
Preferred embodiment scheme, the transfer tank tank mouth are provided with the first locking member 1, and first locking member 1 is used for object
When material transfer, the transfer tank and drying chamber are locked.Transfer tank and drying chamber are sealed locking by locking member,
It avoids air in material transfer process, tank interior is entered by tank mouth, is in contact with material.
Preferred embodiment scheme, the tank body lower half portion are foldable cylinder, and the cylinder uses flexible material, along column
Body short transverse is fixed with support rod 5, and the support rod 5 is embedded in tank wall, and the support rod 5 uses elastic material system
At 5 bottom end of support rod is fixed in the fixed pedestal 6 of tank base setting, and 5 top of support rod is fixed on tank body
The junction of upper and lower half point, the tank body lower half portion is along the direction rotary folding parallel with the tank mouth.As a kind of tool
Body, the junction of the tank body upper and lower half point is provided with rigid anchor (for example, steel ring), the supporting bar top with
The rigid anchor of tank body upper and lower half point junction is fixed.The mode of support rod 5 is inlayed in tank body lower half portion, can be with
Tank body is effectively supported.Support rod 5 is made using elastic material, and 5 both ends of support rod are all consolidated with tank body
Fixed mode can make when applying tank body along the parallel power in tank mouth direction, and tank body lower half portion can be along filling mouth side
To the mode of rotary folding, existing air in tank body can be excluded at this time, and the storage that also can be convenient transfer tank arranges.
