Description
Technical field
The utility model belongs to transportation system technical field, and in particular to a kind of slurry delivery system.
Background technique
In lithium battery pole slice production process, slurry as a raw material for production needs to carry out in conveyance conduit defeated over long distances
Send, conveying after the completion of also need to clear up conveyance conduit, with prevent residual slurry solidify after block conveyance conduit and influence
Conveying next time of slurry.
Pulp of lithium ion battery transportation system generally refers to slurry delivery apparatus of the slurry from agitator tank to coating die head.It is existing
The working method of the slurry delivery system (as shown in Figure 1) of technology is: opening the first ball valve 201 ' and the second ball valve 202 ', slurry
Material is transported to transfer tank 4 ' from blender 1 ' through the first diaphragm pump 2 '；The slurry of transfer tank 4 ' is transferred to by the second diaphragm pump 5 '
Head tank 7 ' is internal；The slurry of head tank 7 ' forms a closed loop circulating system by screw pump 8 ' and coating machine 9 ', is being coated with
When, reflux line 30 ' is closed, and the slurry of head tank 7 ' is constantly conveyed to coating machine 9 ', and when being coated with stopping, opening return pipe
Road 30 ', slurry just constantly recycle between head tank 7 ' and coating machine 9 ', to avoid slurry sediment and introduce bubble, influence subsequent
It is coated with pole piece quality.Since general 7 ' volume of head tank is much smaller than slurry transfer tank 4 ', so head tank 7 ' is equipped with level detection
Mechanism just exports a control signal when detecting the liquid level of head tank 7 ' lower than setting value, and control transfer tank 4 ' arrives head
Second diaphragm pump 5 ' of tank 7 ' is opened, and slurry is just transferred to head tank 7 ' from transfer tank 4 ', when 7 ' liquid level of head tank reaches highest
When limit, the second diaphragm pump 5 ' is shut off.Such slurry delivery system can have the disadvantage that one, second at work
When diaphragm pump 5 ' is closed, it is at static condition from transfer tank 4 ' to slurry in the pipeline of head tank 7 ', slurry is easy to happen heavy
It forms sediment, the defects of when coating is easy to produce bubble, scratch；Two, between transfer tank 4 ' and head tank 7 ' equipped with reflux line 30 ' and
The triple valve 6 ' manually controlled, but reflux line 30 ' is only enabled when being coated with and shutting down, and normally off is in when production, is caused
The deposition of 30 ' slurry of reflux line；Three, the triple valve 6 ' manually controlled needs manual operation by workers when working, and working efficiency is low,
Production cost is big；Four, the slurry delivery system of the prior art is conveyed using single channel, and working efficiency is low.
Meanwhile when producing line does not produce, whole slurry transportation system needs to clean, and the cleaning method that the prior art is taken is
Blender 1 ', transfer tank 4 ' and head tank 7 ' are manually cleaned, and by filter 31 ', filter core 103 ' and coating machine 9 ' into
Row disassembly, cleaning carry out circulation flushing to feeding pipe and the second diaphragm pump 5 ' by way of beating deionized water, by all groups
Part cleaning finishes to be assembled again.There are drawbacks for this cleaning way in the industrial production: instantly when secondary production, pipe-line system is past
It is past poor with slurry wetability because of dry, it causes coating generating bubble when reproducing, reduces production efficiency, cleaning way is urgently
Optimization.
