First hydraulic arm 41 and the second hydraulic arm 51 are connected with external hydraulic pump.
Operation principle：When in use, leading screw 31 can be driven to rise first with elevator 32, then driving reinforcing lid
3 rise to leakage feeding mouth 21, and after feeding mouth 21 puts into reactant, then reinforcing lid 3 can push again, in this state,
Need drive the first hydraulic arm 41 allow sealing cover 4 with fermentation 2 complete seal of tower body.At this point, make reinforcing lid 3 and fermentation tower body 2 with
And sealing cover 4 constitutes the space of an isolation, preferably anaerobic bacteria can be allowed to breed, so, when not feeding, need
Sealing cover 4 is buckled in the bottom position of fermentation tower body 2 always.And since reinforcing lid 3 is to push, on the one hand not only reinforce lid 3
Pressing action, the breeding and diffusion of microorganism can be convenient on the other hand to allow reinforcing the more closely knit of these reactant pressures
Lid 3 is also discharged the air among reactant, is conducive to the life of microorganism.It of courses, when reinforcing lid 3 pushes, also can
Play the role of similar hairbrush, the inner wall for the tower body 2 that ferments is clean.
Reinforcing lid 3 is of coursed during pushing, has a degree of compressed air, at high pressure, part
Air can be escaped from fermentation tower body 2 and reinforcing 3 edge slot of lid or the gap fermented between tower body 2 and sealing cover 4.But it sends out
2 inside of ferment tower body keeps the state of isolation air to play a very important role microorganism, therefore more reliable discharge is due to reinforcing
