Abstract
The utility model discloses a biological pulping system for papermaking, which comprises a biological treatment pond for preparing coarse pulp and a pressing crusher, and is provided with a condensation device, a pulp tower, a medium consistency refiner and a refining device which sequentially treat the coarse pulp. According to the biological pulping system, the coarse pulp is beaten into a first high consistency deslagger for deslagging and enters an oblique spiral condenser to be condensed, is regulated by the pulp tower and enters the medium consistency refiner by self-priming, so that 7 units and sets of motor equipment are reduced compared with the prior art, and an energy-saving purpose is achieved. Because the pulp is carried out slag removal and condensed in the early period of pulp refining, the pulp supply concentration is stabilized, the pulp forming quality of a paper machine when the paper machine runs at high speed is improved, the pulp forming first-level rate is improved from 94 percent to 99.8 percent, and high yield and high quality are realized.
Description
Technical field
The utility model relates to paper making equipment, relates in particular to a kind of bio-pulping system, is used to prepare the required paper pulp of paper.
Background technology
Paper pulp or its bullion generally are divided into low-consistency stock (below 7%, being generally 3-5%) according to solid content; Middle concentration paper pulp (7-15%) and high consistency pulp (more than 15%) are handled the paper pulp of variable concentrations and are just selected dissimilar fiberizers for use.
Referring to Fig. 1, at present the bio-pulping system utilizes biological treatment tank to carry out Biological Pretreatment raw material (like cotton stalk etc.), utilizes disintegrating mill with rolls to make thick slurry again, thick slurry handle through low dense fiberizer after filter, the defibrination apparatus processes obtains finished product paper pulp.
Filtration, defibrination device can be HC Cleaner, pressurized screen and the many disc pulping machines of successively material being handled.
Existing bio-pulping system not only energy consumption is high, and because low dense fiberizer can only be handled the thick slurry of low concentration, and the pulping fiber content is on the low side, and material is in the pump course of conveying, and flow is influenced by electric power and fluctuates, pulping concentration is unstable, influences quality of finished paper.
The utility model content
The utility model provides a kind of and can save energy and reduce the cost, the stable bio-pulping system that supplies slurry concentration.
A kind of bio-pulping system that is used for paper comprises the biological treatment tank and the disintegrating mill with rolls that are used to prepare thick slurry, is provided with enrichment facility, slurry tower, middle-density refiner and filtration, the defibrination device successively thick slurry handled.
As preferably, be provided with first HC Cleaner that is used to remove the gred between described disintegrating mill with rolls and the enrichment facility.
Described enrichment facility is the inclined screw thickener, can material concentration be increased to 6-8%, and described middle-density refiner can be increased to 8-12% with material concentration.
Described filtration, defibrination device can adopt prior art, for example adopt second HC Cleaner, pressurized screen and the many disc pulping machines of successively material being handled.
As preferably, be provided with the semi-finished product stock tank that is used to deposit material between described middle-density refiner and the filter.
As preferably, described middle-density refiner is that three parallel connections are used.
Each equipment of the utility model bio-pulping system is not strict restriction on the position, mainly is can be communicated with successively or be connected through material pipeline or conveyer according to the order to material.
The thick slurry of the utility model bio-pulping system is squeezed into first HC Cleaner slagging-off back entering inclined screw inspissator slurries is concentrated;, the slurry tower take the self-priming mode to get into middle-density refiner after regulating again; Reduce 7 covers of motor device according to original technology, realized energy-conservation purpose.Owing to taked defibrination to remove the gred in earlier stage, concentrate, stablized confession slurry concentration, improved the quality of paper machine pulping in high-speed cruising, the pulping ratio of first-grade products brings up to 99.8% by 94%, has realized high-yield high-quality.
Description of drawings
Fig. 1 is the structured flowchart of existing bio-pulping system;
Fig. 2 is the structured flowchart of a kind of bio-pulping of the utility model system.
The specific embodiment
Referring to Fig. 2; A kind of bio-pulping system that is used for paper of the utility model comprises and successively material being handled or biological treatment tank, disintegrating mill with rolls, first HC Cleaner, inclined screw thickener, slurry tower, middle-density refiner, semi-finished product stock tank, second HC Cleaner, pressurized screen and many disc pulping machines of transfer storage.
When using, the utility model bio-pulping system utilize biological treatment tank to carry out Biological Pretreatment raw material (like cotton stalk etc.); Utilize disintegrating mill with rolls to make thick slurry again; Thick slurry utilizes the inclined screw thickener that material concentration is increased to 6-8% after the slagging-off of first HC Cleaner; Behind the slurry tower, utilize middle-density refiner can material concentration be increased to 8-12%; And change the semi-finished product stock tank over to, obtain finished product paper pulp after handling through second HC Cleaner, pressurized screen and many disc pulping machines (for example two disc pulping machine) again.
The utility model bio-pulping system concentrates owing to taked defibrination to remove the gred in earlier stage, has stablized to supply slurry concentration, has improved the quality of paper machine pulping in high-speed cruising.
