Pathogenic microorganism, parasitic ovum, heavy metal that border has undesirable effect etc..Sludge is carried out into innoxious, recycling treatment, is generation
An important topic of ecological environmental protection in the range of boundary.
Traditional method for sludge treatment includes throwing sea (or directly discharging), landfill and Composting, but all exists to ring
The negative effect (water pollution, soil layer pollution and air pollution etc.) in border and the occupancy of space resources (soil and Shui Chang) and
The shortcomings of waste, forbidden or discarded by increasing industrial country.
Some method for sludge treatment and device are developed successively at present, to expect that reducing the harmful substance in sludge contains
Amount, and secondary recovery utilization is carried out to it by Treatment of Sludge.Wherein, it is a kind of effective dirt that pyrohydrolysis treatment is carried out to sludge
Mud processing means.Existing sludge hot hydrolysis process for treating is primarily present following deficiency：（1）, sludge is heated in heating process
Speed is slow, and the heat time is long, and treatment effeciency is low；（2）, using sludge in tank body interlayer heating tank so that Sludge Surface temperature is high,
And it is less to be heated inside sludge, easily there is the halfway phenomenon for the treatment of.
The content of the invention
Shortcoming it is an object of the invention to overcome prior art, there is provided a kind of efficiency of heating surface it is high for sludge hydrolytic at
The hollow agitating shaft of reason equipment oil bath heating, while stirring, the surface of stirring vane is internally heated to sludge so that
Sludge is heated evenly, and pyrohydrolysis treatment is more thorough.
The purpose of the present invention is achieved through the following technical solutions：It is a kind of for sludge hydrolytic processing equipment oil bath heating
Hollow agitating shaft, including axis body and stirring vane, polylith stirring vane are laid on axis body along the axial direction of axis body, in the axis body
The hollow-core construction axially penetrated through along it is provided with, cavity is provided with the stirring vane, the shaft-body side being connected with the stirring vane
Wall is provided with the through hole that can connect cavity and hollow-core construction.
Further, feed tube is additionally provided with the cavity, the feed tube passes through through hole, and stretches into hollow-core construction.
Further, diameter of the diameter of the feed tube less than through hole.
Further, the side wall of the axis body being connected with same stirring vane is provided with multiple through holes, and each through hole is along axis body
Be radially arranged, and a feed tube is equipped with each through hole.
Further, the porch of the hollow-core construction is provided with a distributing damper.
Further, cross-sectional area of the size of the distributing damper less than hollow-core construction.
The present invention has advantages below：
1st, the present invention is respectively provided with hollow-core construction by by axis body and stirring vane, and to being passed through high-temp liquid in hollow-core construction（Than
Such as high-temperature oil liquid）, high-temp liquid flows in hollow-core construction so that realize heat with sludge inside in the surface of axis body and stirring vane
Transmission, completes to sludge inside agitating heating, it is to avoid because tank body interlayer heating sludge is heated uneven situation, improve plus
The thermal efficiency, while so that sludge hot hydrolysis process is more thorough.
2nd, feed tube is set in the cavity of stirring vane so that high-temp liquid is flowed into stirring vane by feed tube,
Be back in hollow-core construction by cavity again, into stirring vane high-temp liquid in the cavities when with the external world carry out heat friendship
Change, high-temp liquid is circulated in stirring vane, prevent high-temp liquid to be trapped in cavity, the heating of stirring vane
Continuation is good.
3rd, distributing damper is set in the porch of hollow-core construction so that the high-temperature oil liquid entered from hollow-core construction entrance is carried over
The surface of distributing damper shunts to both sides, consequently facilitating into the cavity of stirring vane.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
In figure：1- axis bodies, 2- stirring vanes, 3- hollow-core constructions, 4- through holes, 5- cavitys, 6- feed tubes, 7- distributing dampers.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to following institute
State.
As shown in figure 1, a kind of hollow agitating shaft for sludge hydrolytic processing equipment oil bath heating, including axis body 1 and stir
Blade 2 is mixed, polylith stirring vane 2 is laid on axis body 1 along the axial direction of axis body 1, be provided with what is axially penetrated through along it in the axis body 1
Hollow-core construction 3, is provided with concentric axle center pipe in hollow-core construction 3, cavity 5 is provided with the stirring vane 2, with the stirring
The side wall of axis body 1 of the connection of blade 2 is provided with the through hole 4 that can connect cavity 5 and hollow-core construction 3, sets hollow by by axis body 1
Structure 3 and stirring vane 2 set cavity 5, and to being passed through high-temp liquid in hollow-core construction 3（Such as high-temperature oil liquid）, high-temp liquid
The flowing in hollow-core construction 3, and enter in cavity 5 so that realize that heat is passed with sludge inside in the surface of axis body 1 and stirring vane 2
Pass, complete to sludge inside agitating heating, it is to avoid because tank body interlayer heating sludge is heated uneven situation, improve heating
Efficiency, while so that sludge hot hydrolysis process is more thorough.
Further, feed tube 6 is additionally provided with the cavity 5, the feed tube 6 passes through through hole 4, and stretches into hollow-core construction
In 3, feed tube 6 is connected with the axle center pipe in hollow-core construction 3, and cavity 5 is formed by through hole 4 and axle center pipe and axis body 1
Cavity is connected so that high-temp liquid enters in rear Lee's typing feed tube 6 from axle center pipe, and sky is exited into from the termination of feed tube 6
In chamber 5, high-temp liquid by through hole 4 from cavity 5 in the cavity that axle center is managed and axis body 1 is formed is flowed into so that is entered and is stirred
The high-temp liquid cyclicity for mixing blade 2 is strong, prevents high-temp liquid to be trapped in cavity 5, and the heating and continuous property of stirring vane 2 is good.
Further, diameter of the diameter of the feed tube 6 less than through hole 4.
Further, the side wall of the axis body 1 being connected with same stirring vane 2 is provided with multiple through holes 4, each edge of through hole 4
Axis body 1 is radially arranged, and is equipped with a feed tube 6 in each through hole 4.
The porch of the axle center pipe of the hollow-core construction 3 is provided with a distributing damper 7, and the size of the distributing damper 7 is less than
The cross-sectional area of axle center pipe so that the surface that the high-temperature oil liquid entered from axle center tube inlet carries over distributing damper 7 shunts to both sides,
Consequently facilitating into finally flowing into cavity 5 in the feed tube 6 of stirring vane 2.
The course of work of the invention is as follows：Axis body 1 is connected with swivel joint, axis body 1 in rotation process, by rotation
Joint to being passed through high-temperature oil liquid in the axle center pipe in hollow-core construction 3, in the porch of the axis pipe of hollow-core construction 3, by shunting
Baffle plate 7 is shunted to high-temperature oil liquid, and high-temperature oil liquid flows to the both sides of distributing damper 7, is entered in cavity 5 by feed tube 6,
So that being full of high-temperature oil liquid in cavity 5, heat exchange is carried out with sludge in whipping process, sludge receives pyrohydrolysis, heat exchange
During high-temperature oil liquid afterwards is back to the cavity that axle center pipe is formed with axis body 1 from through hole 4, so as to realize whole hollow agitating shaft pair
Sludge is stirred while heating.
