Description
Technical field
The present invention relates to field of papermaking, particularly a kind of diffusing slurry system and a kind of diffusing sizing process that in this diffusing slurry system, looses and starch.
Background technology
The diffusing slurry of paper process (claiming pulping again) workshop section is known by in the industry.Through the slurry that looses, can make the fiber initial gross separation in the paper making raw materials such as solid-state slurry, waste paper or broken, for the beol of slurry is got ready.
Diffusing slurry is divided into diffusing slurry of batch (-type) and the diffusing slurry of continous mode.So-called batch (-type) looses after slurry is meant that a certain amount of slurry drops into starch dispensing machine and accomplishes the slurry that looses and be removed, and carries out the diffusing slurry of other one batch slurry again, and the loose process of slurry of each batch is discontinuous.
The diffusing slurry process process of present batch (-type) generally comprises following steps:
1) according to the size and the ability of starch dispensing machine, throw in the raw material of constant weight, wherein can comprise solid-state slurry, waste paper and broken, cooperate a certain amount of water, to reach optium concentration;
2) start starch dispensing machine, use mechanical mode to loose slurry to the purpose that reaches fiber separation fully;
3) if be necessary, heating (steam) or add the intensity agent of dissociating in the said process, or the agent of dissociating of heating and intensity is used simultaneously;
4) after diffusing slurry was accomplished, the slurry in the dilution starch dispensing machine pumped slurry to finite concentration again from the below;
5) get back to first step, the next circulation of beginning.
The defective that above-mentioned diffusing sizing process exists is:
1) broken is broken up at the state of doing, and the damage that fiber is caused is bigger, the character of influence process control and one-tenth paper.
2) broken has different forms, and diffusing paper is arranged, and the paper that breaks into bag is also arranged, and is difficult to the amount of the each charging of regulation and control.
3) inlet amount can't accurately estimate to cause the concentration meeting of diffusing slurry inaccurate.
4) when the slurry concentration demand of loosing is low; Interaction between fiber and the fiber is less; The fiber separation of broken relies on the effect of mechanical energy to reach fully; No matter how advanced the design of starch dispensing machine and rotor thereof is, all can cause injury to a certain degree to fiber, and then influence paper strength.
5) inlet amount can't accurately be estimated also can cause adding when intensity is dissociated agent and can't accurately estimate, thereby causes unnecessary waste or the not enough situation of addition.
6) broken is stacked and is taken more space.
Summary of the invention
In view of this, be necessary to provide a kind of diffusing sizing process that can eliminate above-mentioned defective and diffusing slurry system for implementing that this diffusing sizing process is provided with.
A kind of diffusing sizing process comprises the steps:
Utilize baling press, with the raw material packing, this raw material comprises broken under temperature and humidity condition;
With the wet feed material input block after the packing that needs quantity in advance and in buffering area, be detained certain hour;
Wet feed material is promoted through storing and the traffic zone by buffering area again, and gets in the starch dispensing machine, quantitatively adds to accomplish once behind the water reinforcedly, and slurry then looses;
In starch dispensing machine, accomplish diffusing slurry back and form slurry and taking-up.
A kind of diffusing slurry system comprises baling press, is used under temperature and humidity condition, raw material being packed; The buffering area that is connected with baling press; Be used for keeping in the wet feed material after packing, storage that is connected with buffering area and traffic zone reach the starch dispensing machine that links to each other with the traffic zone with storage; Said storage and traffic zone are used for wet feed material is passed in the starch dispensing machine, and starch dispensing machine is used to accomplish loose slurry and formation slurry.
Compared with prior art, diffusing sizing process provided by the invention has following advantage:
1) raw material broken thorough aquation under temperature and humidity condition is soft, expands, and hydrogen bond tentatively divides, and can reduce in the existing slurry process of loosing pure mechanism to the damage of fiber.
2) frictional force between paper and the paper reduces because of humidifying, can improve the normal slurry concentration 2-3% that looses.That is to say that reaching under the prerequisite of identical diffusing slurry concentration, technology of the present invention is compared with traditional technology, needs less time and energy, therefore the effect brought of diffusing sizing process of the present invention is the improvement of productivity, and the reduction of specific energy consumption.
3) fiber in the raw material is reduced by the infringement of mechanical force, has stablized production process and has improved the intensity that becomes paper.
4) humidity of the warm and humid packing process of broken is certain, has controlled each diffusing slurry amount effectively, thereby can stablize the diffusing slurry of control concentration, reduces the waste of energy and chemicals, has avoided the low fiber infringement that causes of diffusing slurry concentration.
5) sizing process can reduce the slurry intensity of loosing because the present invention looses, and therefore impurity in the raw material broken such as plastic sheet is also had the better protection effect, can make these impurity keep big relatively shape, is beneficial in follow-up technology its removal.
6) broken packing buffering has also been extenuated broken simultaneously and has been stacked the problem that takies more space.
With reference to the accompanying drawings, in conjunction with specific embodiment the present invention is done further description.
