Description
Technical field
The invention belongs to pipeline processing technical fields, and in particular to one kind is carrying out water for workpiece such as boilers and pressure vessels
After pressure test, make the inner wall of the pipe Minton dryer of pipeline drying.
Background technology
The workpiece such as boilers and pressure vessel are after hydraulic pressure test is carried out, and particularly there are a large amount of bend pipes, bend pipe memories for workpiece
Water cannot be completely exhausted out, and ponding can cause corrosive pipeline to get rusty, and influence life of product, in addition product ponding may cause transport and
Low temperature icing in storage installation process causes the quality accident of frost crack pipe, therefore current way is blown using compressed air
It sweeps, it is impossible to fully erased pipeline internal moisture.
Invention content
The purpose of the present invention is to propose to a kind of inner wall of the pipe Minton dryers, overcome the above-mentioned deficiency of the prior art,
Its structure design is simple, easy to use, saves the time, improves efficiency, ponding is avoided to cause corrosion, avoids product ponding that from may leading
The low temperature icing in transport and storage installation process is caused to cause the quality accident of frost crack pipe.
In order to reach above-mentioned purpose of design, the technical solution adopted by the present invention is as follows：
A kind of inner wall of the pipe Minton dryer, including screw vacuum pump, pipeline, rubber plug, tracheae, air intake structure,
The bleeding point of the screw vacuum pump is connected by pipeline with the sealing of air intake structure one end, and the air intake structure other end, which is equipped with, to lose heart
Valve, the air intake structure side wall are tightly connected tracheae one end, and the tracheae other end is tightly connected pipeline, the spiral shell by rubber plug
The pipeline that bar vacuum pump is connected with air intake structure is equipped with ball valve, and needle-valve is connected in parallel on ball valve on the pipeline, and needle-valve passes through pipeline
Connect dew point hygrometer sensor.
The air intake structure seals cut-in pressure table, gauge measurement negative pressure of vacuum value.
The dew point hygrometer sensor passes through connection to electric cabinet.
The vacuum pump is equipped with cooling water inlet, cooling water outlet.
Silencer is additionally provided on the vacuum pump, is discharged containing water gas by silencer.
Inner wall of the pipe Minton dryer advantageous effect of the present invention is：Its structure design is simple, easy to use, section
Make an appointment, improve efficiency, ponding is avoided to cause corrosion, avoid product ponding may cause to transport and store it is low in installation process
Temperature, which freezes, causes the quality accident of frost crack pipe.
At normal temperatures, moisture flashes to steam under certain negative pressure of vacuum, this equipment establishes vacuum pick-up system, makes to deposit
Water evaporation by detecting the water content of exhaust outlet in real time, determines whether inner wall of the pipe is dried, reaches drying purpose.
Its advantage specifically further includes：
1st, the moisture evaporating completely in duct work can be come out at normal temperatures, ponding is avoided to cause corrosion.
2nd, the moisture evaporating completely in duct work can be come out at normal temperatures, avoids product ponding that from may causing to transport
Cause the quality accident of frost crack pipe with the low temperature icing in storage installation process.
3rd, it avoids workpiece slinging turn draining, saves the time, improve efficiency.
4th, duct work can slightly be heated, evaporation rate can be improved.
5th, rubber plug can form sealing under negative pressure of vacuum, and connection is quick.
Description of the drawings
Fig. 1 is the schematic diagram of inner wall of the pipe Minton dryer of the present invention.
Specific embodiment
