Description
Technical field
The present invention relates to a kind of reclaim equiment of pulp liquor, be specifically related to a kind of digester circulation heating structure.
Background technology
Modern paper industry is the third-largest processing industry occupied in the world after telecommunications manufacturing industry and auto industry, belongs to concentration degree high, fund, technology, energy-intensive large-scale modernization basic industry.Papermaking equipment industry is for paper industry provides the professional mechanical industry of production equipment special, spare parts and components and installation, maintenance service, and the output of papermaking equipment and equipment, level, quality play conclusive effect to the production and construction scale of China's paper industry, technical equipment, product quality class, production cost and economic benefit.
Digester is a kind of visual plant in paper-making process, the raw material such as China's big or middle paper mill many employings fixing vertical digester boiling timber, bamboo, reed, reed.The major advantage of vertical digester is: the volume of pot is large, and paste producing amount is large; Labor productivity is high; Compared with isometric rotary spherical digester, floor space is little.Existing digester, when boiling, after the raw material of boiling and liquid are added digester, is only in digester, pass into steam carry out boiling, although steam has the effect of stirring to liquid, but mixing effect is not good, not being utilized completely of liquid, thus cause cooking effect not good.
Summary of the invention
For the defect that above-mentioned prior art exists, the object of the present invention is to provide one can improve liquid utilization rate, thus make the better digester circulation heating structure of cooking effect.
For achieving the above object, technical scheme of the present invention is:
Digester circulation heating structure, comprise digester, described digester top and bottom are equipped with inlet, wherein, also be provided with annular filter screen, screen holder, connector, circulating pump and liquid adapter, described screen holder is connected in the middle part of digester, described annular filter screen is arranged on screen holder, the two ends of annular filter screen are connected with digester inwall by described connector, the digester inwall that described annular filter screen two ends are relative is equipped with pipe joint, a pipe joint is communicated with the inlet of digester upper end by liquid adapter, another pipe joint is communicated with the inlet of digester lower end by liquid adapter, two liquid adapters are equipped with circulating pump.
When adopting technique scheme, raw material is added digester from the charging aperture of digester upper end, in digester, passes into liquid from the inlet of digester top and bottom, bottom digester, then pass into steam boiling is carried out to raw material.In the process of boiling, open two circulating pumps, liquid in digester enters in annular filter screen, raw material is isolated in outside annular filter screen, the digester inwall that annular filter screen two ends are relative is equipped with pipe joint, a pipe joint is communicated with the inlet of digester upper end by liquid adapter, another pipe joint is communicated with the inlet of digester lower end by liquid adapter, so the liquid in one of them pipe joint enters in the inlet of digester upper end through liquid adapter, liquid in another pipe joint enters in the inlet of digester lower end through liquid adapter, thus the liquid in digester is circulated, reach the object making full use of liquid.The present invention is by the liquid circulation in digester, and the flowing of liquid in digester is more abundant, makes raw material fully contact liquid in digestion process, so can improve cooking effect.
Further, described screen holder comprises at least three cross bars and multiple clamping rings, and described many cross bars are arranged in parallel and are that regular polygon is arranged, described clamping rings surrounds on cross bar, and arrange along cross bar length direction, cross bar welds with clamping rings or screw is connected.During installation, annular filter screen is arranged in annular space that bar surrounds, and is connected by screw on cross bar, so just annular filter screen can be installed firmly.
Further, described annular filter screen is connected with screen holder by screw.The mode that screw connects is simple, is convenient to installation and removal.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of digester circulation heating structure embodiment of the present invention;
Fig. 2 is the schematic diagram of annular filter screen one end and digester coupling part in digester circulation heating structure embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
As depicted in figs. 1 and 2, a kind of digester circulation heating structure, comprise digester 1, digester 1 top and bottom are equipped with inlet 2, wherein, also be provided with annular filter screen 3, screen holder 4, connector 5, circulating pump 6 and liquid adapter 8, screen holder 4 is connected in the middle part of digester 1, annular filter screen 3 is arranged on screen holder 4, the two ends of annular filter screen 3 are connected with digester 1 inwall by connector 5, digester 1 inwall that annular filter screen 3 two ends are relative is equipped with pipe joint 7, a pipe joint 7 is communicated with by the inlet 2 of liquid adapter 8 with digester 1 upper end, another pipe joint 7 is communicated with by the inlet 2 of liquid adapter 8 with digester 1 lower end, two liquid adapters 8 are equipped with circulating pump 6.
In the present embodiment, screen holder 4 comprises three cross bars and three clamping rings, and three cross bars are arranged in parallel and are that equilateral triangle is arranged, clamping rings surrounds on cross bar, and arranges along cross bar length direction, and cross bar welds with clamping rings.During installation, annular filter screen 3 is arranged in annular space that cross bar surrounds, and is connected by screw on cross bar, so just annular filter screen 3 can be installed firmly.
