Wherein: 1 is seal box, 2 is motor, and 3 is telescopic hydraulic cylinder, and 4 is gas shield curtain, and 5 is fermented liquid, and 6 is stirring body, and 601 is stirrer paddle, and 602 is hydraulic motor, and 7 is support post, and 8 is reactor, and 9 is pulley, and 10 is pull rope, and 11 is door。
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described。
As shown in Figure 1; the present invention includes seal box 1, motor 2, telescopic hydraulic cylinder 3, gas shield curtain 4, stirring body 6, support post 7, reactor 8, pulley 9 and pull rope 10; wherein being filled with fermented liquid 5 in reactor 8, the fermented liquid 5 of the present invention can be the anaerobic fermentation raw materials such as feces of livestock and poultry, agricultural wastes (straw) or trade waste (distiller grains)。
The top of reactor 8 has hole, and the lower surface at top is provided with telescopic hydraulic cylinder 3；The telescopic hydraulic cylinder 3 of the present invention is two, and one end of each telescopic hydraulic cylinder 3 is fixed on the lower surface at reactor 8 top, and the other end is outfan, and is connected to gas shield curtain 4 on the output, and this gas shield curtain 4 drives lifting by telescopic hydraulic cylinder 3。The material of gas shield curtain 4 is PVC (polrvinyl chloride) film, and gas shield curtain 4 also has hole, and corresponding with the hole that reactor 8 top is offered, and passes through for stirring body 6。
Reactor 8 top is sealedly connected with seal box 1, and the hole that reactor 8 top is offered is positioned at seal box 1, has the door 11 that can be taken off stirring body 6 in any surface of seal box 1。The lower end of support post 7 is rotatably installed in the bottom of reactor 8, and upper end is positioned at the top of reactor 8, and it is internal to cover in seal box 1。Support post 7 can manual rotation or by power source drive rotate, rotational angle is up to 270 °。Motor 2 and pulley 9 it is separately installed with in the upper end of support post 7。Stirring body 6 is positioned at reactor 8, and including stirrer paddle 601 and hydraulic motor 602, hydraulic motor 602 is arranged on support post 7 by slideway, and relative support column 7 liftable also can rotate with support post 7；Stirrer paddle 601 is connected with the outfan of hydraulic motor 602, hydraulic motor 602 drive stirring fermented liquid 5。One end of pull rope 10 is connected with the outfan of motor 2, and the other end is walked around by pulley 9, is connected with hydraulic motor 602。Stirring body 6 both can rotate with support post 7, it is also possible to is driven lifting by motor 2。
The operation principle of the present invention is:
When the agitating device of the present invention works, stirring body 6 is positioned at fermented liquid 5。Stirrer paddle 601 rotates under the driving of hydraulic motor 602, by the parameter set, fermented liquid 5 is stirred；According to technological requirement, stirring body 6 can also being made to rotate along with support post 7, support post 7 can drive stirring body 6 to carry out 270 ° of rotations in reactor 8, and different are axially stirred with normal direction position simultaneously；Under the driving of motor 2, pull rope 10 can also drive and move up and down, and be fixed on the height being arbitrarily designated, fermented liquid 5 is stirred, there is good stirring and hold concurrently shell breaking function。Thus the fermented liquid 5 in reactor 8 can be carried out all angles, being sufficiently stirred for of each position。
During the agitating device normal operation of the present invention, the telescopic hydraulic cylinder 3 that gas shield curtain 4 connects is in contraction state, and gas shield curtain 4 clings to the top of reactor 8。When stirring body 6 and needing to overhaul, motor 2 drives stirring body 6 to rise, and sequentially passes through telescopic hydraulic cylinder 3 and the hole at reactor 8 top, rises in seal box 1, and motor 2 quits work。In the process, telescopic hydraulic cylinder 3 drives the gas shield curtain 4 connected to decline, and covers fermented liquid 5, serves as the effect at interim reactor 8 top。Open the door 11 on seal box 1, stirring body 6 is taken out by seal box 1；After stirring body 6 is removed, seal box 1 is closed immediately, and reactor 8 is temporarily properly functioning。After stirring body 6 maintenance, stirring body 6 is sent back in seal box 1, and hydraulic motor 602 is connected with pull rope 10, motor 2 drive stirring body 6 to reset；Meanwhile, gas shield curtain 4 being promoted to by telescopic hydraulic cylinder 3 top clinging to reactor 8, reactor 8 recovers properly functioning。
In the process that the present invention overhauls outside stirring body 6 tank, the internal still proper motion of reactor 8, it is not necessary to fermented liquid 5 and biogas are bled off, it is to avoid cause waste and affect project benefit, not affecting during maintenance and normally produce biogas。
