Abstract
The utility model relates to a paper machine pressurized screen pipeline connecting structure advances to starch pipeline and dilute fluid pipeline at a side -mounting of pressurized screen, and thick liquid pipeline and tail slurry pipeline are installed out to the opposite side of this pressurized screen, the bottom installation scum pipe way of this pressurized screen, pressurized screen shell inner wall spiral card covers the one deck cooling tube, and cooling water inlet and coolant outlet are connected respectively to the both ends of this cooling tube. Through install parts such as valve, pressure sensor on the pipeline of pressurized screen, guaranteed stable, the reliable work of pressurized screen, the controllability is strong. Through install the one deck cooling tube at pressurized screen shell inner wall, effectively the operating temperature of pressure reduction sieve prolongs its life. The utility model discloses simple structure, the design scientific and reasonable, the design ingenious, have the value of extensive popularization and application.
Description
Technical field
The utility model 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 at an equipment with pressure step sizing slurry under complete totally enclosed state, tangentially entered the separation chamber on pressurized screen top during operation by pulp-inlet pipe with pressure, unscreened slurry, the sedimentation that is separated under the influence of centrifugal force of heavier object is discharged from slag-drip opening.Slurry overflow is crossed circular weir plate and is entered screen cylinder and rotation downwards and revolve screening area between cylinder, and qualified fiber is drawn by good slurry grout outlet by sieve aperture (seam); Underproof fiber continues to move downward, and discharges bottom pressurized screen from scum pipe.
The handling difference of traditional pressurized screen, job insecurity, service life are short, often break down, significantly reduce operating efficiency.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of paper machine pressurized screen pipeline jointing construction.
Scheme of the present utility model is achieved in that
A kind of paper machine pressurized screen pipeline jointing construction, slurry pipeline and diluent liquid pipeline is installed in the side of pressurized screen, the opposite side of this pressurized screen installs pulp pipeline and tail slurry pipeline, Residue extraction pipeline is installed in the bottom of this pressurized screen, described pressurized screen outer casing inner wall spiral note covers one deck cooling tube, and the two ends of this cooling tube connect cooling water inlet and coolant outlet respectively.
And, setting pressure sensor and valve on described pulp-inlet pipe road.
And, described pulp pipeline is provided with flowmeter.
And the end mounted valve of described pulp pipeline, by-pass valve control is installed by described diluent liquid pipeline, mounted valve on described Residue extraction pipeline.
Advantage of the present utility model and good effect are:
By being provided with the parts such as valve, pressure sensor on the pipeline of pressurized screen, ensure that pressurized screen is stable, reliably working, controllability is strong.By installing one deck cooling tube at pressurized screen outer casing inner wall, effectively reducing the operating temperature of pressurized screen, extending its service life.The utility model structure is simple, design science rationally, be skillfully constructed, there is the value of wide popularization and application.
Accompanying drawing explanation
Fig. 1 is syndeton schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail.
A kind of paper machine pressurized screen pipeline jointing construction, as shown in Figure 1, is installed into slurry pipeline 1 and diluent liquid pipeline 13 in the side of pressurized screen 4, the opposite side of this pressurized screen installs pulp pipeline 5 and tail slurry pipeline 8, and Residue extraction pipeline 10 is installed in the bottom of this pressurized screen.
Innovative point of the present utility model is:
1, setting pressure sensor 2 and valve 3 on described pulp-inlet pipe road, to enter to starch pressure in time, operating pressure difference, distinguish that whether operation is normal.
2, described pulp pipeline is provided with flowmeter 6, to understand throughput, ensures that pressurized screen is stable, at the end mounted valve 7 of pulp pipeline.
3, by-pass valve control 12 installed by described diluent liquid pipeline; Mounted valve 9 on described Residue extraction pipeline.
4, described pressurized screen outer casing inner wall spiral note covers one deck cooling tube (not shown), the two ends of this cooling tube connect cooling water inlet 11 and coolant outlet 11A respectively, this structural design effectively can reduce the operating temperature of pressurized screen, increases the service life.
The utility model has the advantages of for:
By being provided with the parts such as valve, pressure sensor on the pipeline of pressurized screen, ensure that pressurized screen is stable, reliably working, controllability is strong.By installing one deck cooling tube at pressurized screen outer casing inner wall, effectively reducing the operating temperature of pressurized screen, extending its service life.The utility model structure is simple, design science rationally, be skillfully constructed, there is the value of wide popularization and application.
It is emphasized that; embodiment described in the utility model is illustrative; instead of it is determinate; therefore the utility model comprises the embodiment be not limited to described in detailed description of the invention; every other embodiments drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope of the utility model protection equally.
