Description

A kind of bamboo refines the pretreatment unit of lignin

Technical field

The utility model relates to pulp technology for making paper, especially a kind of bamboo refines the pretreatment unit of lignin.

Background technique

Traditional lignin production be bamboo is crushed, the black liquor that is formed after boiling is concentrated, and to concentration after Black liquor be modified, lignin is formed after spray drying.Although entire technique is highly developed, entire process costs Height, prime cost are the boiling of bamboo and the concentration of black liquor；Traditional bamboo boiling be steamed by water, such as: Title: the implementation method of broken bamboo boiling, the patent No.: 201410611620.9, due to being using steam spraying, which is produced The low black liquor of raw concentration is very more, substantially increases subsequent concentration cost, and the temperature steamed is not high, can generate half-cooked existing As.Bamboo will be made into fibrous raw material, it is necessary to be crushed to bamboo, existing be crushed using bamboo crusher, bamboo Sub- crusher includes conveyer belt, crushing device, storage compartment, motor and power supply, and existing bamboo crusher has no idea to detect bamboo Whether by artificial implanted metal in son, now some it is artificial be greedy for small gains, metal is implanted into bamboo, is be easy to cause brokenly in this way Broken machine damage；And there is no any limiting device on existing conveyer belt, and if root bamboo is put on the belt in this way, bamboo When entering crushing device, occasional is fallen on the ground, and this processing efficiency is low.Further, since bamboo chip amount needed for papermaking is more, Disposable boiling requires as unit of ton, and therefore, volume and efficiency to pot all require, i.e., existing digesting apparatus must The problems such as there is boiling efficiencies low, waste of human resource, charging and discharging bother.Such as patent name: broken bamboo chip boiling dress It sets, the patent No.: 201410611596.9；Although it solves the problems, such as charging, in digestion process since lye sprays not Uniformly (bamboo chip irregularly causes), and steam pipework can not accomplish that entire boiling cavity temperature is uniform, therefore, with steamed rice one There are half-cooked phenomenons for sample, and the broken bamboo chip that boiling comes out can all black not by lye spray, seriously affect product Quality increases significant cost for subsequent pulp washing.In addition, existing lye spray is to be mixed with boiling, will lead in this way The generation of more black liquor causes pressure for the processing of subsequent black liquor, and the cost of black liquor processing is the problem of entire industry, It does not handle well, will result in the destruction of environment；And using the time in one pond of technology boiling is usually 6 ~ 8 hours.There is mirror In this, the utility model proposes the pretreatment units that bamboo refines lignin.
