Abstract
The invention discloses improved equipment and an improved method for separating a heavyweight part during waste paper conversion. The equipment is provided with a material dissolver (1) and a precipitator (16). The material dissolver (1) is connected with the precipitator (16) for separating the heavyweight part. The heavyweight part (10) in waste paper is deposited in a precipitation tower (15), and can be removed from the precipitation tower (15) by utilizing tongs (13). According to the equipment, the precipitator (16) is also provided with a heavyweight part valve (17) besides the tongs (13), and the heavyweight part valve (17) can also be used for removing the heavyweight part (10). The method is executed by the equipment. According to the equipment and the method, the heavyweight part can be separated in an improved way, and an operator is hardly required.
Description
Technical field
Formed present subject matter for leaching/dissolve waste paper, have material leach device (
) and the equipment of settler.At this, the heavies be included in waste paper deposits in precipitator tower, and handgrip then can be utilized to be removed.Same formation present subject matter be the method be separated with heavies for leaching/dissolving waste paper, described method rely on perform according to equipment of the present invention.
Background technology
When processing waste paper, often application precipitator tower carries out heavies separation, and in precipitator tower, the heavies be included in waste paper is deposited.This precipitator tower leaches device (pulper Pulper) by corresponding outlet greatly and material and is connected in lower area.The fibrous suspension discharged from thick heavies leaves precipitator tower by overflow part.The heavies be separated in precipitator tower is such as metallic member, as bolt, clip, nail, or stone, glass etc., even once found in precipitator tower complete motor sub-assembly (
).
Then, heavies periodic is removed by handgrip (such as many jaw handgrip) from precipitator tower, and this heavies is correspondingly processed.Although utilize handgrip to be removed by very large heavies without any problems, handle handgrip with needing operator's periodic.Which results in extra cost.
The heavies separator of same application not with handgrip.At this, relate to be close upward, with the deposition vessel of the heavies valve in bottom.In the upper area of this deposition vessel, have the overflow part for fibrous suspension, wherein, the overflow part of deposition vessel is in the below of liquid level in pulper.Although this deposition vessel works satisfactory, larger heavies may block described heavies valve.This obstruction occurs all the more continually owing to becoming more and more worse waste paper quality (especially in Asia), and whole pulper may be caused long for downtime.In addition, also may occur at overflow part place blocking in this deposition vessel, in this case, pulper must be cleared, and opens the inspection opening of deposition vessel, and this also spends with height and is associated.
Summary of the invention
Therefore, the present invention is based on following task, that is, provide following equipment, the heavies that described equipment achieves improvement is separated, and needs operator hardly.
Described task is resolved by the settler with precipitator tower, and this precipitator tower also has heavies valve except handgrip.In the device, separation of heavy part is carried out by heavies valve.Such heavies separation scheme needs operator hardly.Easily can remove large heavies by handgrip, and also can be removed the blocking of overflow part by handgrip, avoid longer downtime thus.
Heavies valve preferably has two valves, between two valves, have valve pocket.Thus, heavies can be discharged from heavies valve, and not affect heavies separation thus.
At this, preferably by bottom valve timing (getaktet) discharge heavies.
Advantageously, flushing line is passed in valve pocket.By this flushing line, can when bottom valve close and the valve on top open, water is flowed to valve pocket.Be attached to fiber residue on deposited heavies separated like this and be washed in fibrous suspension.
Also be contemplated that, above precipitator tower, be furnished with spray nozzle.Then, by this spray nozzle, the heavies utilizing handgrip to promote from precipitator tower can be discharged from fiber residue.
Same formation present subject matter be a kind of correlation method for leaching waste paper, wherein, leach in device at material and leach waste paper, and be removed with the heavies that material leaches in the settler (precipitator tower with handgrip is combined with the heavies valve on the bottom side at precipitator tower) that device is connected.According to the present invention, by the most heavies of heavies valve carrying-off.
Preferably, by settler, 20 to the 50 volume % being formed at the fibrous suspension that material leaches in device are guided, thus, can be ensured that good heavies is separated.
Advantageously, heavies valve timing ground runs.
Accompanying drawing explanation
Below, the present invention is introduced by reference to the accompanying drawings.Wherein:
Fig. 1 illustrates the diagrammatic side view of the conventional heavies separation scheme according to prior art;
Fig. 2 illustrates the schematic side elevation according to equipment of the present invention.
Detailed description of the invention
In these two accompanying drawings, identical Reference numeral represents identical element respectively.
The conventional equipment be separated for heavies shown in Figure 1.This equipment comprises material and leaches device l (pulper Pulper), and material leaches utensil rotor 2, sieve 3 and good slurry chamber 5.Be in operation, waste paper and water flowed to material and leaches device 1, leach at this waste paper and form fibrous suspension 4.At this, material leaches process and is assisted support by rotor 2.The major part of the fiber leached is arrived in good slurry chamber 5 by the sieve 3 below rotor 2.Then, in order to continue to process, good slurry 6 is flowed to other unit.
The part of the fibrous suspension 4 and heavies 10 be particularly included in waste paper leaves pulper as screening reject 11, and arrive in precipitator tower 15, there, heavies 10 is at the bottom deposit of precipitator tower 15.Suspension 12 leaves precipitator tower 15 by overflow part 14, and inputs to the hazardous waste handlers 7 (removing gob machine (De-Trasher)) for further processing procedure.Heavies 10 is removed with handgrip 13 by periodic from precipitator tower 15.
Exemplarily illustrate for according to the embodiment leaching the equipment be separated with heavies for material of the present invention in fig. 2.Here, settler 16 is equipped with heavies valve 17 extraly.This heavies separator 17 is arranged in the below of precipitator tower 15 and has two valves 8 and 9.Valve pocket 20 is defined by these two valves 8 and 9.
In normal operation, discharge most of heavies 10 by heavies valve 17.At this, generally open the valve 8 on top and close the valve 9 of bottom.So heavies 10 is accumulated continuously in valve pocket 20.By flushing line 18, above valve 9, water is imported in valve pocket 20.By these water by the fiber that is such as attached on heavies 10 from valve pocket 20 refunds to precipitator tower 15.
At regular intervals and at the latest when valve pocket 20 is full of by heavies 10, stop conveying flushing water, shutoff valve 8 and open valve 9, then, heavies 10 is fallen a container from valve pocket 20.Afterwards, shutoff valve 9 and again open flushing pipe 18 and valve 8 again.
Utilize handgrip 13 from settler 16, remove large heavies 10, this point can otherwise periodic ground carries out, or to carry out when heavies valve 17 blocks.In addition, handgrip 13 is utilized also easily can to remove the blocking of overflow part 14.
In the present embodiment, on precipitator tower 15, spray nozzle 19 is furnished with.Can by spray nozzle 19 by with Water spray by the heavies 10 that promotes from precipitator tower 15 with handgrip 13.Thus, so the fiber residue on heavies 10 is washed out by spray and arrives again in suspension circulation.
