Abstract
The present invention relates to a kind of paper machine pressurized screen pipeline jointing construction, slurry pipeline and diluent liquid pipeline are installed in the side of pressurized screen, the opposite side of the pressurized screen installs pulp pipeline and tail slurry pipeline, the bottom of the pressurized screen is installed by Residue extraction pipeline, the pressurized screen outer casing inner wall spiral note covers one layer of cooling tube, and the two ends of the cooling tube connect cooling water inlet and coolant outlet respectively.By the parts such as valve, pressure transducer are provided with the pipeline of pressurized screen, it is ensured that pressurized screen is stable, reliably working, controllability is strong.By one layer of cooling tube being installed in pressurized screen outer casing inner wall, effectively reduce the operating temperature of pressurized screen, extend its service life.Present configuration is simple, design science is reasonable, be skillfully constructed, the value with wide popularization and application.
Description
Technical field
The invention belongs to field of papermaking, especially a kind of paper machine pressurized screen pipeline jointing construction.
Background technology
The pressurized screen of paper machine is, in an equipment with pressure step sizing slurry in the state of completely enclosed, to carry during operation
Pressure, unscreened slurry are by pulp-inlet pipe tangentially into the separation chamber on pressurized screen top, the work of heavier object in centrifugal force
The sedimentation that is separated with is discharged from slag-drip opening.The excessively circular weir plate of slurry overflow is downwardly into the screening between screen cylinder and rotation rotation cylinder
Area, qualified fiber are drawn by good slurry grout outlet by sieve aperture (seam)；Underproof fiber continues to move downward, in pressurized screen
Discharge from scum pipe bottom.
The handling difference of traditional pressurized screen, job insecurity, service life are short, and Jing often breaks down, and significantly reduces work
Efficiency.
The content of the invention
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of paper machine pressurized screen pipeline jointing construction.
What the solution of the present invention was realized in：
A kind of paper machine pressurized screen pipeline jointing construction, is installed into slurry pipeline and diluent liquid pipeline, the pressure in the side of pressurized screen
The opposite side of power sieve installs pulp pipeline and tail slurry pipeline, and Residue extraction pipeline, the pressurized screen inside the shell are installed in the bottom of the pressurized screen
Wall spiral note covers one layer of cooling tube, and the two ends of the cooling tube connect cooling water inlet and coolant outlet respectively.
And, pressure transducer and valve are installed on the pulp-inlet pipe road.
And, effusion meter is installed on the pulp pipeline.
And, valve is installed in the end of the pulp pipeline, and control valve, the scum pipe are installed on the diluent liquid pipeline
Valve is installed on road.
Advantages of the present invention and good effect are：
By the parts such as valve, pressure transducer are provided with the pipeline of pressurized screen, it is ensured that pressurized screen is stable, reliably working,
Controllability is strong.By one layer of cooling tube being installed in pressurized screen outer casing inner wall, effectively reduce the operating temperature of pressurized screen, extending which makes
Use the life-span.Present configuration is simple, design science is reasonable, be skillfully constructed, the value with wide popularization and application.
Description of the drawings
Fig. 1 is the attachment structure schematic diagram of the present invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings and by specific embodiment.
A kind of paper machine pressurized screen pipeline jointing construction, as shown in figure 1, being installed into slurry pipeline 1 and dilute in the side of pressurized screen 4
Fluid pipeline 13 is released, the opposite side of the pressurized screen installs pulp pipeline 5 and tail slurry pipeline 8, and deslagging is installed in the bottom of the pressurized screen
Pipeline 10.
The present invention innovative point be：
1st, pressure transducer 2 and valve 3 are installed on the pulp-inlet pipe road, to enter to starch pressure in time, operating pressure difference is distinguished
Whether operation is normal.
2nd, effusion meter 6 is installed on the pulp pipeline, to understand throughput, it is ensured that pressurized screen is stable, in grout outlet
The end in road is installed by valve 7.
3rd, control valve 12 is installed on the diluent liquid pipeline；Valve 9 is installed on the Residue extraction pipeline.
4th, the pressurized screen outer casing inner wall spiral note covers one layer of cooling tube (not shown), and the two ends of the cooling tube connect respectively
Cooling water inlet 11 and coolant outlet 11A, the structure design can effectively reduce the operating temperature of pressurized screen, increase the service life.
Advantages of the present invention effect is：
By the parts such as valve, pressure transducer are provided with the pipeline of pressurized screen, it is ensured that pressurized screen is stable, reliably working,
Controllability is strong.By one layer of cooling tube being installed in pressurized screen outer casing inner wall, effectively reduce the operating temperature of pressurized screen, extending which makes
Use the life-span.Present configuration is simple, design science is reasonable, be skillfully constructed, the value with wide popularization and application.
It is emphasized that embodiment of the present invention is illustrative, rather than it is determinate, therefore the present invention is including simultaneously
The embodiment being not limited to described in specific embodiment, it is every to be drawn by those skilled in the art's technology according to the present invention scheme
Other embodiment, also belongs to the scope of protection of the invention.
