The beneficial effects of the invention are as follows：The agitating device of agitating type composting reactor, which needs to stretch into inside compost, to be stirred
It mixes, sludge runner is worn on agitating device, sludge can be passed through in compost and be heated and make moisture evaporation, realize dehydration, reasonably
Design the length or circulation area of sludge runner, you can realize that moisture content when sludge discharge meets relevant criterion, it is highly practical,
It is energy saving.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples：
Fig. 1 is the structural schematic diagram of the present invention；
Fig. 2 is the operating diagram of sludge grinding device.
Specific implementation mode
Referring to Figures 1 and 2, the present invention is a kind of agitating type composting reactor, agitating device is equipped with, on the agitating device
It is equipped with sludge runner 3.
In the compost reactor applied to tube structure, agitating device includes mixing arm 2 and actuating arm 1, the drive
The middle part of 1 vertical connection mixing arm 2 of swing arm, actuating arm 1 are connected with transmission device, are rotated around actuating arm 1 with controlling mixing arm 2
And/or lifting.Specifically, the actuating arm 1 and mixing arm 2 are hollow structure, mixing arm 2 forms one by inner hollow and houses
Chamber, accommodating cavity be connected to actuating arm 1 inside it is hollow, the sludge runner 3 is arranged in accommodating cavity.Since mixing arm 2 passes through drive
Swing arm 1 is rotated and is rotated, and is stirred, is overturn to compost, and heat exchange, the sludge are carried out in order to make sludge come into full contact with compost
3 Spiral distribution of runner is on the side wall of accommodating cavity.When installation, the upper end of 3 slave drive arm 1 of sludge runner is passed through, then is arranged in appearance
Intracavitary is set, realizes the concealed design of sludge runner 3, it is beautiful, the work of agitating device is not influenced.In addition sludge runner 3 also may be used
1 outside of direct slave drive arm is inserted into accommodating cavity.In order to reinforce the stirring work of mixing arm 2, the mixing arm 2 is equipped with spiral
Paddle.The auger leaf can be both arranged around 1 spiral of actuating arm, can also be arranged around 2 spiral of mixing arm.The transmission device
Using common driving mechanism.
In the compost reactor applied to stacking type, the agitating device is equipped with a moving trolley, pacifies in moving trolley
Equipped with driving mechanism, the lower end of moving trolley is equipped with screw rod, the driving mechanism drive connection screw rod, to control screw rod
Rotation.Wherein moving trolley can move back and forth in the stacking reactor body of strip, stretched into compost and rotated by screw rod
And compost is overturn.The sludge runner 3 is arranged on screw rod, is carried out heat exchange to import sludge in compost, is heated
Evaporable water realizes dehydration.Specifically, the screw rod is hollow structure, the sludge runner 3 is penetrated from the upper end of screw rod
It is exported in it and from the upper end, the sludge runner 3 is arranged in screw rod inside spin, and the screw rod surface is equipped with spiral
Leaf.
Due to belonging to liquid when the moisture content of sludge is more than 85%, moisture content belongs to plastic state in 65%-85%, and is less than
65% belongs to solid-state.The sludge that sewage treatment plant has just generated, moisture content is usually 90% or more, and sludge in the present embodiment
When being discharged from sludge runner 34, moisture content is less than 80%, belongs to plastic state, in order to facilitate subsequent processing (as made fertilizer or filling out
It is full), the discharge end of sludge runner 3 connects a sludge grinding device, and the sludge grinding device is used for sludge fine crushing.Specifically,
The discharge end of the sludge grinding device is equipped with an orifice plate 4, and the orifice plate 4 is equipped with several discharge holes 5, and sludge passes through orifice plate 4
Shear action form the sludge of several fine strip shapes, realize processing fine crushing.Further, which is docked one
It is dehydrated conveyer belt, sludge fine crushing is conveyed from conveyer belt, and conveyer belt both ends setting dry-air blast road send the sludge on conveyer belt
The wind of wind, feeding first passes through dehumidifying, is re-fed into, and then takes away the moisture in sludge, realizes further dehydration.
In conclusion the hot environment of present invention combination compost reaction, the agitating device of agitating type composting reactor needs
It stretches into inside compost and is stirred, sludge runner 3 is worn on agitating device, sludge can be passed through in compost and be heated and moisture be made to steam
Hair realizes dehydration, the rational length or circulation area for designing sludge runner 3, you can realizes moisture content symbol when sludge discharge
Relevant criterion is closed, it is highly practical, it is energy saving.
