Abstract
The utility model relates to a blockage-preventing polyester pipeline device, in particular to the blockage-preventing polyester pipeline device designed for a glycol conveying pipeline in polyester production. The blockage-preventing polyester pipeline device comprises a pump, a front scraping plate and a rear scraping plate which are orderly connected through pipelines. The blockage-preventing polyester pipeline device is structurally characterized in that: the pipeline between the front and rear scraping plates is provided with a front cleaning pipe and a rear cleaning pipe, wherein the front cleaning pipe is close to the front scraping plate and is provided with a cleaning agent inlet valve; and the rear cleaning pipe is provided with a cleaning agent outlet valve. The blockage-preventing polyester pipeline device has the advantages of rational structure design, convenience for cleaning the pipelines and little influence on production in cleaning.
Description
Technical field
The utility model relates to a kind of anti-blocking polyester tube duct device, particularly a kind of anti-blocking polyester tube duct device at ethylene glycol conveyance conduit design in the production of polyester.
Background technique
At present, in the production of polyester of China, the ethylene glycol pipeline is stopped up by polyester oligomer easily, causes the vacuum system cisco unity malfunction, and the traditional treatment method cost is higher, and bigger to producing steady influence.Through the analysis to original pipeline obstruction, we find that this obstruction Main Ingredients and Appearance is a polyester oligomer.The tradition sweep-out method comprises machinery, alkali cleaning etc.But when cleaning, often need whole system to quit work, therefore have the processing cost height, producing the big shortcoming of influence with chemical.
Summary of the invention
Technical problem to be solved in the utility model provides that a kind of reasonable in design, pipeline are convenient to clean, the anti-blocking polyester tube duct device of little impact on production when cleaning.
It is this anti-blocking polyester tube duct device that the utility model solves the problems of the technologies described above the technological scheme that is adopted, comprise the pump, front scrapping plate, the back scraper plate that link to each other by pipeline successively, its structural feature is: scavenge pipe and back scavenge pipe before the pipeline between described front scrapping plate and the back scraper plate is provided with, preceding scavenge pipe is near front scrapping plate, preceding scavenge pipe is provided with the washing agent cut-in valve, and back scavenge pipe is provided with washing agent and picks out valve.
The angle of scavenge pipe, back scavenge pipe and pipeline is 45 degree before described in the utility model.
The utility model is compared with prior art and is had the following advantages and effect: owing on pipeline, be provided with preceding scavenge pipe and the back scavenge pipe that is used for injecting with the sucking-off washing agent, pipe blow-through that can be convenient, little impact on production need not be stopped work basically.Angle between preceding scavenge pipe, back scavenge pipe and the pipeline is reasonable, work that can be convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with embodiment the utility model is described in further detail, following examples are to explanation of the present utility model and the utility model is not limited to following examples.
Embodiment 1: as shown in Figure 1, present embodiment is made up of pump line road 10, pump 2, front scrapping plate 3, connecting tube 1, preceding scavenge pipe 6, back scavenge pipe 7 and back scraper plate 4.Pump 2 is connected by pump line road 10 with front scrapping plate 3, and front scrapping plate 3 is connected by connecting tube 1 with back scraper plate 4.Before scavenge pipe 6 be arranged on the connecting tube 1 position near front scrapping plate 3, back scavenge pipe 7 is arranged on the connecting tube 1 position near back scraper plate 4, the angle of preceding scavenge pipe 6, back scavenge pipe 7 and connecting tube 1 is 45 to spend.Preceding scavenge pipe 6 is provided with washing agent cut-in valve 8.Back scavenge pipe 7 is provided with washing agent and picks out valve 9.
When system normally moves, washing agent cut-in valve 8 and washing agent pick out valve 9 and are in closed condition, when the polyester oligomer obstruction takes place when, open washing agent cut-in valve 8 and washing agent and pick out valve 9, washing agent is entered connecting tube 1 from washing agent cut-in valve 8, clean, then washing agent and the obstruction that washes out are picked out sucking-off the valve 9 from washing agent, reach the purpose of pipe blow-through. so, cleaning will be faster, convenient, little to the influence that production causes, processing cost also reduces.
The utility model is on probation in the permanent intra-company of containing of paulownia elder brother group, the processing of repeatedly removing obstruction, and effect is fine.
In addition, need to prove, the specific embodiment described in this specification, its zero, the shape of parts, institute's title of being named etc. can be different.Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
Claims (2)
