Description
Technical field
The present invention relates to paper making equipment technical fields, and in particular to a kind of pulping system of Environment-friendlyfood-grade food-grade true qualities bamboo pulp.
Background technology
At present, the fast development of paper industry makes the Chinese major producing country for having become world's papermaking product in global range
And country of consumption, output and consumption figure Jun Ju second places of the world.And the shortage of paper making raw material and the environmental pollution of paper industry are asked
Topic becomes the biggest problem for restricting China's Paper Industry Development already.
China is the most abundant country of world's bamboo resource, has the category of bamboo plant about 39, more than 500 plant, national bamboo grove and hair
Bamboo grove area ten thousand hm about more than 5002, resource very abundant is known as the title of " bamboo kingdom ".In order to alleviate the shortage of wood raw material,
Paper industry increasingly payes attention to the research application to bamboo class, and various bamboo class paper products come into being.In processing and fabricating food-grade sheet
During color bamboo pulp, without being bleached, only totally it can be used with by slurry washing.It produces and fills in existing food-grade true qualities bamboo pulp
In putting, in its conveying process, since the bamboo wood fines after slicer shreds is with moisture, conveying device is easily adhered to
On, and in conveying operation reverse-running section, the scraper plate of conveying device is in Open Side Down, the effects that due to gravity and mechanical shock
The influence of power, the tablet for sticking in scraper plate bottom originally are just easily shaken off to inside conveying device, in the course of time, it will cause
Tablet is accumulated in its bottom, is formed and blocked, and the components such as conveying device crash, damage motor are also resulted in when serious.The prior art
Also lack a kind of pulping system that can effectively prevent conveying device blocking.
Invention content
It is an object of the invention to：For the prior art pulping system conveying process due to bamboo wood fines have adhesion
Property and adhesion on a conveyor, are easy to cause bamboo wood fines and are deposited in conveying device bottom, cause conveying device dead when serious
Machine, the problem of burning motor, provide a kind of pulping system of Environment-friendlyfood-grade food-grade true qualities bamboo pulp, can effective guarantee conveying device not by
Bamboo wood fines blocks, and improves the stability of equipment operation.
The technical solution adopted by the present invention is as follows：
A kind of pulping system of Environment-friendlyfood-grade food-grade true qualities bamboo pulp, the pretreatment including being set gradually by bamboo material conveying track fill
Put, conveying device, steaming plant, spraying device, washing apparatus arranged and spin-drying device；
