The specific embodiment

Explain with reference to Figure of description 1 with below 2 pairs of corrugated paper process unitss works of the present utility model of accompanying drawing.

Corrugated paper process units of the present utility model, its structure comprises conveyer, pulper, HC Cleaner, defibrator, decker and disc mill, described conveyer, pulper, HC Cleaner, defibrator is connected successively with decker, be provided with shake frame plansifter and pressurized screen between described defibrator and the decker, described pressurized screen links to each other with disc mill, described decker links to each other with wastewater treatment equipment, described wastewater treatment equipment comprises trench, collecting tank, elevator pump and sedimentation basin, be provided with grid between described trench and the collecting tank, be provided with elevator pump between collecting tank and the sedimentation basin, described collecting tank links to each other with pulper by sludge pump respectively with sedimentation basin, described grid links to each other with pulper by the waste residue pump, and the top of described sedimentation basin links to each other with defibrator with pressurized screen respectively.

Described sedimentation basin is further regulated water quality and quantity, makes it to be tending towards more balanced; Utilize sedimentation theory with mud and moisture from, make sludge settling, the clear liquid come-up; The bottom surface of described sedimentation basin is designed to inclined-plane 2, and inclined-plane 2 gradients are i=0.01, and puddle 3 at the bottom of the pond is set, and makes mud can concentrate on puddle 3 at the bottom of the pond, then with sludge pump with the pond at the bottom of the mud in puddle 3 be extracted into reuse in the pulper; Simultaneously above sedimentation basin one jiao be provided with clear liquid overfall 1, make the clear liquid after the processing flow automatically to defibrator and pressurized screen from overfall 1.

Described trench adopts brick mix structure, lays the cement groove face, is open type from the workshop to the collecting tank raceway groove, above the lay cover plate, be convenient to periodic cleaning, groove face is gradient from high to low, so that the smooth and easy mobile nothing of recirculated water is stopped up.

Described grid is installed according to 60-70 ° of inclination angle, interval of grid strip 20mm.After entering grid, most suspended substances is stopped, and relies on movable rack regularly to remove suspended matter at the grid place.

Described collecting tank structure is mixed cement plaster for the underground type brick.The water quality and quantity that sewage produces in the technological process process is all inhomogeneous, and therefore designing a collecting tank regulates water quality and quantity, makes it progressively to be tending towards balanced; The sewage water temperature difference that each stage produced in the process of pulping and paper-making, collecting tank can be regulated water temperature, makes it to reach consistent; It is standby that collecting tank is made accident pool simultaneously, when sedimentation basin in maintenance overhaul, cleaning during mud, collecting tank can temporarily be used for storage process sewage.

Described elevator pump adopts model: 250S-14S, flow: 420m3/h, lift: 10m, power: 18.5kw.Main effect is that the water after collecting tank is stablized is extracted in the sedimentation basin.

Slurrying workshop section:

1) waste paper is delivered to by conveyer and is carried out repulping of waste paper in the pulper, simultaneously waste residue and mud introducing pulverizer is pulverized simultaneously, is mixed.

2) send HC Cleaner to remove heavy seeds such as stone, iron filings;

The paper pulp that comes from pulper tangentially is pumped into HC Cleaner from the HC Cleaner top, by the impeller action of rotating at a high speed near the slurry porch, make slurry in scummer, do rotatablely moving of high speed, be subjected to action of centrifugal force accordingly, slurry moves downward by screw line, the heavy seeds that density is big in the slurry is subjected to action of centrifugal force to be thrown to wall greatly, slowly rotates the whereabouts along wall, is deposited in the dirt trap.Feed a certain amount of press water in dirt trap, the good fiber of sneaking in the impurity is reclaimed in dilution, and thick slag is regularly discharged by residual cake valve and transported to reuse in the pulper, and good slurry is done screw upwards and flowed out along middle grout outlet outer wall.

3) slightly starch after removing heavy seeds, discongest into fiber through defibrator.

4) paper pulp screens through the frame plansifter vibrations of shaking then; Good slurry feed pressure sieve, waste residue flows into the screenings pond and regularly transports to the pulper reuse.

5) through after the further screening of pressurized screen process, acceptable fiber enters machine hand's section after sending decker to concentrate to good slurry again;

In order to improve the corrugated paper product quality, in production technology, increased the pressure screening system, slurry utilizes the normal pressure of pressure differential inside and outside the screen cylinder and rotor head as screening power in pressurized screen, the pressure pulse that utilizes the rotor high speed rotary to be produced plays the self-cleaning effect, unscreened slurry tangentially enters screen cylinder continuously from stock inlet, acceptable fiber flows to outside the screen cylinder by sieve aperture, enter decker through good slurry pipe, slag slurry scum pipe through the bottom under the promotion under slurry stream and the rotor of staying in the screen cylinder is discharged, and returns the disc mill correct grinding.

After the good slurry that comes from pressurized screen enters the net groove of decker, because the inside and outside liquid level difference of net, make in water filter in the slurry networks.Discharge from the drainpipe of an end.Fiber is stayed online formation grout layer, and by being taken out of the water surface, is transported to pressure roller from rotary screen cage, will concentrate slurry from pressure roller with scraper again and blow off and enter stock tank and machine hand's section; The water of getting rid of from decker flows automatically to the wastewater treatment equipment processing through trench.

6) waste residue that comes from pressurized screen enters behind the disc mill under the huge centrifugal action of high speed rotating plate, mind-set circumferencial direction motion from disc mill, fiber is subjected to various effects such as frictional force, torsion, shearing, waterpower and heating power in this process, the processing that fiber was torn, divided silk, brooming, conquassation, bending and rubs.Sending pressurized screen after the processing back to recycles.

The grid of the whole waste water of slurrying workshop section before trench flows automatically to collecting tank stopped most suspended substances, relies on grid suspended matter regularly to be removed and delivered to the pulper reuse; And the waste water after filtering enters collecting tank, make water quality, the adjusted equilibrium of the water yield, most of mud sinks, and simultaneously also adjustable water saving temperature rises to sedimentation basin by sewage pump again, mud is further separated with water, mud sinks, and clear liquid rises, through the regular hour processing, supernatant directly is back to defibrator and pressurized screen by overfall 1, and the mud in collecting tank and the sedimentation basin is delivered to reuse in the pulper by slush pump.

Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
