Description
Technical field
The invention belongs to pulp technology for making paper, specially a kind of wood chip Dynamic sampling machine.
Background technique
Large-scale slurrying enterprise usually purchases wood chip as primary raw material, and supposedly, a lot of wood chips seem one species,
But its inside contains wood chip of different sizes, light color and dark wood chip, the different wood chip of size and shape and countless rulers
Very little similar and end is the wood chip of angle or angle.The size distribution of wood chip in the non-uniform chip pile of a pile size,
It is extremely influential on subsequent process.For its size, the speed ratio of larger-size wood chip slurrying is lesser
Wood chip is slow, and slurrying speed difference is to the place of paper pulp after the production of paper pulp, the quality of paper pulp, the running of cooker, cooker
Reason, pulp sifting and cleaning, fine grinding etc. have very far-reaching influence.In addition, the chemical analysis of wood chip is also not consistent, i.e.,
Make to be same one tree, the fiber content in young timber than be in the timber grown up it is low, this represent with trunk central part
Wood chip made of part is different with wood chip made by the timber of trunk periphery.The density of timber is to mechanically manufacturing paper pulp
The lax raw material for having an important influence, and being used in machinery pulping process, its wooden content is than containing from autumn wood
Amount is lacked.Similarly, in terms of newsprint production, the color of timber is to paper pulp chemical treatments and bleached chemical processing side
Formula has a great impact, so using the wood chip of light color and keeping this light colour is particularly important to the quality of mechanical pulping
's.
In summary, the quality of wood chip has tremendous influence to pulping process in chip pile.It must acquire a series of
Sample analyzes them and is classified, and the NATURAL DISTRIBUTION situation of wood chip in chip pile is inferred to this.If at will selecting one
Heap wood chip simultaneously collects one bag of wood chip at its edge, cannot reflect and represent dividing naturally for wood plate size size in chip pile certainly
Cloth situation.In fact, to obtain a representational sample can be a very arduous and challenging thing: specific
Sampling plan, sampling spot, the sampling equipment specially designed, sample program and it is other etc. the problems such as, it is necessary to consider week
In detail, representative sample can be obtained.
Currently, Wood chips for the pulp sampling is (to be examined wood in every batch of according to " Wood chips for the pulp " national standard 2.4.1 sampling regulation
The top of piece heap and the front, rear, left and right among heap respectively select a sampled point in 400-500 grams of each point sampling, sample total amount not
Less than 2000 grams) carry out manual sampling.Artificial sample has the drawbacks of large labor intensity, inefficiency, and artificial sample meeting
Be considered being unfair because the corrupt practice of personnel can arbitrarily operate sampling as a result, causing supplier to appeal in turn
Or various disputes, the demand and management for not being able to satisfy feed stream development require, and are to perplex slurrying production and wood chip buying always
Problem.
Summary of the invention
The purpose of the present invention is in view of the above problems, providing a kind of wood chip Dynamic sampling machine, which is improved
Sampling precision, efficiency eliminate the cheating of manual sampling bring, realize the fair and just of sampling process.
In order to achieve the above object, the technical solution adopted by the present invention is that: a kind of wood chip Dynamic sampling machine, including rack, institute
