Description
Technical field
The present invention relates to sludge treatment device technical field, in particularly a kind of tank for sludge hydrolytic processing equipment
Agitating shaft gas blowing seal structure.
Background technology
Sludge is the byproduct produced in sewage disposal process, and the composition of sludge is extremely complex, mainly contain about 80~
90% moisture, and other organic matter, each type organic, the various trace elements and may be to ring that can be recycled
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.The pyrohydrolysis treatment of sludge is typically stirred under certain pressure, temperature conditionss, therefore in hydrolytic decomposition pot body
Portion is with pressure, and in stirring, the sealing structure between agitating shaft and tank body has following defect：（1）Pressure inside the tank is big, according to
Packing seal, filler easily fails under the erosion of silt, and replacement frequency is high, and sealing effectiveness is bad；（2）Sealed according to machine and installed
In tank body, although can improve sealing effectiveness, but once seal failure, it is very inconvenient that dismounting is safeguarded, maintenance cost is high.
The content of the invention
Shortcoming it is an object of the invention to overcome prior art, there is provided a kind of good sealing effect and easy to maintenance be used for
Agitating shaft gas blowing seal structure in the tank of sludge hydrolytic processing equipment.
The purpose of the present invention is achieved through the following technical solutions：Stirred in a kind of tank for sludge hydrolytic processing equipment
Axle gas blowing seal structure, including seal body, machine envelope and packing seal, the seal body is arranged on the side wall of tank body, close
It is provided with vertically in precipitation cavity, the seal body in envelope body and rotating shaft is installed along axis, near the sealing of tank interior
Body side is provided with stuffing-box, and packing seal is filled with stuffing-box, and gland is provided with the end locking of seal body,
Packing seal is pressed in stuffing-box, packing seal is contacted with rotating shaft cooperation, away from the seal body side peace of tank interior
Equipped with machine envelope, machine envelope is contacted with rotating shaft cooperation, and the air inlet pipe that cavity is connected, work are connected with and precipitated on the side wall of seal body
When making, by air inlet pipe to precipitation cavity in be passed through pressure higher than tank interior pressure gas.
In the seal body precipitation cavity near machine envelope side wall on also tapped hole, the screwed hole built with
Plug.
The screwed hole aligns with air inlet pipe.
The rotating shaft is hollow shaft.
The present invention has advantages below：
1st, packing seal is installed in the seal body on the inside of tank body, fitting machine envelope in the seal body on the outside of tank body, while
To be passed through in the precipitation cavity of seal body pressure higher than pressure inside the tank gas so that precipitation inside cavity gas in tank
Play blowback effect so that the gap that the silt of tank interior is not easy between packing seal and rotating shaft is leaked, greatly reduce
The destruction that silt is sealed to machine, so as to improve sealing effectiveness, and extends the service life of machine envelope.
2nd, using packing seal is built-in and by the way of machine envelope exterior, machine envelope safeguards very convenient, and if packing seal is lost
Effect, its more preferable sealing strip is also very simple, therefore, easy to maintenance, maintenance cost is low.
3rd, plug is additionally provided with seal body, when checking whether packing seal is effective, plug is taken apart, screw thread is observed
Whether there is silt to spray at hole, sealing failure of fillers is represented if having silt to spray, if being sprayed without silt, then it represents that filler is close
Envelope still effectively, plays a part of whether detection packing seal fails.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
In figure：1- seal bodies, 2- precipitation cavitys, 3- rotating shafts, 4- machines envelope, 5- packing seals, 6- glands, 7- air inlet pipe,
8- plugs, 9- tank bodies.
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, agitating shaft gas blowing seal structure in a kind of tank for sludge hydrolytic processing equipment, including sealing is originally
Body 1, machine seals 4 and packing seal 5, and the seal body 1 is arranged on the side wall of tank body 9, is provided with heavy vertically in seal body 1
Rotating shaft 3 is installed along axis in shallow lake cavity 2, the seal body 1, the side of seal body 1 inside tank body 9 is provided with filler
Letter, is filled with packing seal 5 in stuffing-box, gland 6 is provided with the end locking of seal body 1, and packing seal 5 is pressed
Tight in stuffing-box, packing seal 5 is contacted with the cooperation of rotating shaft 3, away from the organic envelope of the side of seal body 1 installation inside tank body 9
4, machine envelope 4 is contacted with the cooperation of rotating shaft 3, and the air inlet pipe 7 that cavity 2 is connected is connected with and precipitated on the side wall of seal body 1, work
When, by air inlet pipe 7 to precipitation cavity 2 in be passed through pressure higher than the internal pressure of tank body 9 gas.
Further, the also tapped hole on the side wall of machine envelope 4 of the precipitation cavity 2 in the seal body 1, at this
Screwed hole can be used to detect whether packing seal 5 fails that expression packing seal 5 is lost if having silt to spray built with plug 8
Effect, if being sprayed without silt, then it represents that packing seal 5 is still effective, so as to play the work whether detection packing seal 5 fails
With.
Preferably, the screwed hole is alignd with air inlet pipe 7, and when taking plug 8 apart, the alignment screwed hole of air inlet pipe 7 is carried out
Blow so that produce negative pressure in precipitation cavity 2, if having silt in precipitation cavity 2, be easier to remove, while so that
The failure of packing seal 5 is more readily detected out.
Further, the rotating shaft 3 is hollow shaft, can be to high-temp liquid is passed through in hollow shaft, in stirring in tank
Sludge is heated, and improves the efficiency of heating surface.
The course of work of the invention is as follows：During work, by air inlet pipe 7 to being passed through pressure higher than tank body 9 in precipitation cavity 2
The gas of internal pressure so that the gas inside precipitation cavity 2 is to playing blowback effect in tank so that the silt inside tank body 9
It is not easy the gap between packing seal 5 and rotating shaft 3 to be blown out under pressure inside the tank effect, so as to play one to packing seal 5
Determine protective effect.When routine inspection is carried out, plug 8 is taken apart, the alignment screwed hole of air inlet pipe 7 is blown so that precipitation cavity 2
Interior generation negative pressure, if having silt in precipitation cavity 2, is easier to remove, while so that the failure of packing seal 5 is easier
Detect, if there is silt to blow out, then it represents that packing seal 5 is failed, it is necessary to be changed to it.
