Description
Technical field
The utility model belongs to paper making equipment technical field, particularly relates to a kind of outlet sieve of grass washing machine.
Background technology
At present, papermaking is mainly divided into wood pulp papermaking and papermaking straw pulp, wood pulp papermaking development is long, technology maturation, because wood pulp papermaking is raw material with forest, and the percentage of forest cover of China is on the low side, make the cost of wood pulp papermaking higher, and certain influence is produced to environment, along with the progress of paper technology, papermaking straw pulp technology obtains tremendous expansion, employing hair grass, cotton stalk, reed, corn stalk, the careless class such as straw is as pulping raw material, without the need to expending forest tree resource, and China is as a large agricultural country, there is abundant agricultural crop straw, these agricultural crop straw parts are by chopping and returning, part abandons waste, much be incinerated in addition, waste resource, and contaminated environment, therefore, development papermaking straw pulp not only can realize resource and make full use of, avoid waste, and energy protection of the environment, there is important social effect and economic benefit.
Inventor is in the practice that this area is long-term, through a large amount of experiment repeatedly, determine a new straw pulp paper making process, save boiling step, grinding and bleaching stage are united two into one, simplifies technique process, achieve fast low temperature to soften simultaneously, the waste water COD produced and colourity reduce greatly, and pollutional load reduces greatly, and waste water can fully recovering.
And in new technology, conveniently at paper industry, particularly can facilitate the pulping of raw material, above-mentioned raw material needs first to carry out break process before manufacture, then the raw material after fragmentation is passed through cleaning, softening, insulation, rub, reaction, grinding, shove, pulp washing, dehydration, the steps such as storage slurry, especially the silt in the papermaking material after fragmentation is removed in raw material cleaning, the impurity such as dust, the carrying out of the follow-up link of direct impact and the quality of paper pulp, in whole paper technology, there is very important effect, and select the wash mill being applicable to raw material cleaning just to seem particularly crucial.
The wash mill of current use is mostly provided with a tank, tank is provided with charging aperture and discharging opening, paper making raw material through necessarily processing enters tank through charging aperture and then discharges from discharging opening, be mingled in the silt in paper making raw material, the bottom that the impurity such as dust are deposited to tank because proportion is larger than water, the bottom of tank is provided with a blow-off pipe, and filter screen is set in the bottom of tank, when opening the switch of blow-off pipe, silt, the impurity such as dust are discharged with sewage through filter screen, for wood pulp papermaking, because first the raw material of wood pulp papermaking is processed into spile, spile generally has matchbox size, 3 ~ 5mm thickness, the impurity contained is less, material cleaning impurity-eliminating effect is fine, but for papermaking straw pulp, raw material due to papermaking straw pulp is all loose in disorder, volume is large, at water float, containing silt, the impurity such as dust are more, the effect of cleaning removal of impurities is undesirable, the material exported from grass washing machine discharging opening is still mingled with some impurity, so directly enter next processing link, affect papermaking quality.
Therefore, for the straw pulp paper making process of inventor's research and development, a kind of specific wash mill of necessary design, makes it meet the demand of technique.
