Abstract
A kind of device preventing vacuum tube from blocking in pop degasification process, for using during vacuum removal abnormal smells from the patient in producing POP, including degassing still and in parallel two set vacuum lines, the most a set of blocking, while blocking pipe can being cleared up, opening another set of vacuum tube to be operated, vacuum line slant setting, available gravity makes tamper flow out.The cleaning of vacuum pipe need not be stopped producing by this utility model, and efficiency is high, labor intensity is low, it is adaptable to industrialized production.
Description
Technical field
This utility model relates to a kind of proofing vacuum tube blocking device, for using during vacuum removal abnormal smells from the patient in producing POP,
Belong to the control technology field of general dirt.
Background technology
POP is polyethers based on polyether polyol (the most general soft bubble polyether triol, polyether polyol with high activity),
Add the vinyl monomer such as acrylonitrile, styrene and initiator, more than 100 DEG C and under nitrogen protection, carry out free radical grafting
The polyhydric alcohol containing organic filler being polymerized.It may replace inorganic filler, not only makes polyurethane foam have higher carrying
Ability and good resilience, also make the foam structure of foam, physical and mechanical properties be improved, and therefore, POP becomes molding
And slab-stock flexible and the important source material of semi-hard polyurethane foam plastic.It is widely used in auto industry, mat material, home decoration
In field.
Industrial conventional initiator is azodiisobutyronitrile, this initiator reaction temperature, efficiency of initiation, price,
The advantage that the aspects such as monomer conversion have uniqueness.But its catabolite is a kind of high-melting-point substances, when removing product odour,
This material can separate out solid particle because of cooling in vacuum line, makes vacuum line block.So, in actual production
In, generally require periodically stopping production, remove blocking material.For clean vacuum pipe pipeline, the most first take vacuum tube apart, will be stifled with instrument
Pipe material is cleaned out, and then reinstalls and could use.This cleaning mode labor intensity is big, and the time of cleaning requirement is relatively
Long.
Utility model content
This utility model provides the device preventing vacuum tube from blocking in a kind of pop degasification process, and it makes vacuum pipe clear up
Process efficiency is high, labor intensity is low, and need not stop when clearing up producing.
Described in the utility model technical problem is that solves by the following technical programs:
A kind of device preventing vacuum tube from blocking in pop degasification process, including degassing still and the first vacuum tube, described first
Vacuum tube connects degassing still by ball valve, and the first vacuum tube slant setting, inclination angle is 1～89 °.
The device preventing vacuum tube from blocking in above-mentioned pop degasification process, described first vacuum tube is arranged in parallel second true
Blank pipe, two vacuum tubes set gradually vacuum valve, steam valve, trimmer valve respectively, and the trimmer valve other end arranges surge tank, buffering
Pot bottom arranges wastewater valve, and surge tank top arranges vacuum gas discharge valve.
The device preventing vacuum tube from blocking in above-mentioned pop degasification process, described steam valve is passed through the pressure of steam and is more than
0.3MPa。
This utility model has the advantage that
This utility model arranges two set vacuum tubes of parallel connection, with one for one, when the most a set of blocking, can carry out blocking pipe
While cleaning, open another set of vacuum tube and be operated, so, it is to avoid need during cleaning to stop production.Vacuum tube 1～89 ° incline
Tiltedly placing, make the material of fouling automatically flow out from vacuum tube under gravity, when cleaning is needed, the top of vacuum tube leads to
Entering to have the steam of certain pressure, the high temperature of steam makes the material melting of plugging, and the plugging material of fusing is risen by the pressure of steam
To the effect rinsed.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure, each label is expressed as: 1, degassing still, and 2, ball valve, 3, vacuum valve, 4, steam valve, the 5, first vacuum tube,
6, trimmer valve, 7, surge tank, 8, wastewater valve, the 9, second vacuum tube, 10, vacuum gas discharge valve.
Detailed description of the invention
Refering to accompanying drawing 1, this utility model includes deaerate still 1 and the first vacuum tube 5, and described first vacuum tube 5 is by ball valve 2
Connect degassing still 1, the first vacuum tube 5 slant setting.Vacuum valve 3, steam valve 4 and trimmer valve is set gradually on first vacuum tube 5
6, trimmer valve 6 other end arranges surge tank 7, arranges wastewater valve 8 bottom surge tank 7.It is arranged in parallel second true on first vacuum tube 5
Blank pipe 9, described second vacuum tube 9 sets gradually vacuum valve 3, steam valve 4 and trimmer valve 6, and trimmer valve 6 other end arranges buffering
Tank 7, arranges wastewater valve 8 bottom surge tank 7.
The angle of inclination of the first vacuum tube 5 described in the utility model and the second vacuum tube 9 is 1～89 °, facilitates tamper profit
Discharge with self gravitation.Steam valve is passed through the pressure of steam more than 0.3MPa, only pressure more than 0.3MPa, vapor (steam) temperature ability
Enough conditions meeting partly or entirely fusing plugging material, play fusing plugging material and rinse the dual function of plugging material,
Surge tank 7 is for alleviating the pressure of the blowout vacuum mouth of pipe, and the flow velocity making waste water discharge is uniform.Vacuum gas discharge valve 10 is in buffering
When tank 7 pressure is excessive, prevents waste water from can not enter surge tank 7 because pressure is excessive and discharge.
During work, pop deaerates in degassing still 1, and after a period of time, vacuum line can block, and now closes blocking true
Blank pipe road, opens standby vacuum line, and now, degasification process is carried out in standby vacuum line, and blocked vacuum line
The most capable of washing.Open the steam valve 4 of blocked vacuum line, trimmer valve 6, wastewater valve 8, in vacuum line, be passed through steam,
Under the high temperature of steam, tamper being cleaned out, waste water is discharged from wastewater valve 8.
Claims (2)
1. preventing the device that vacuum tube blocks in pop degasification process, including degassing still (1) and the first vacuum tube (5), it is special
Levying and be, described first vacuum tube (5) connects degassing still (1), the first vacuum tube (5) slant setting, inclination angle by ball valve (2)
