Abstract
The present invention relates to a kind of continuous steamer, with wood chip and digester, the lower end of described chip bin sets and is connected with wood chip feeder, wood chip feeder is connected with high pressure feeder, high pressure feeder is connected with digester, it is connected with digester at cooking liquor import, described digester is divided into soak band, heating zone, cooking zone and scrubbing section and cooling zone, the bottom of digester is provided with pipeline and is connected with spraying pot.The present invention is simple in construction, and easy to use, dehydrating effect is good, and feeder blade mass dryness fraction is big, and screw feed skidding is not easily caused and regurgitates failure, continuous production and person equipment safety is improved, fixed cost input is small, the big consumption of power is small, and cooking effect is good, improves boiling efficiency.
Description
Technical field
The present invention relates to a kind of continuous steamer.
Background technology
Boiling vessel is that the lignin in paper making raw material is dissolved in into cooking liquor, the equipment for making paper making raw material be separated into fiber.Boiling
It is divided into batch (-type) and the class of continous way two, continuously stewing is carried out continuously from being charged to blowing in digestion process, using even
Continuous boiling vessel, the wood chip feeding chip bin through screening enters boiling simultaneously through wood chip feeder and high pressure feeder with cooking liquor
Pot top, and with decoction together by soak band, heating zone, cooking zone, scrubbing section and the cooling zone of digester, paper pulp is by bottom
Discharge.In actual production operation, existing inclined helix dehydrator is limited because of water separation capability, causes into feeder blade mass dryness fraction
It is small, it is easily caused screw feed skidding and regurgitates failure, the continuous production of influence and person equipment safety.If increasing inclined helix dehydrator
Then fixed cost input is high, power is small consumes big.Boiling vessel is mainly used in the gelatinization of starch fluid.This boiling vessel digestion time is short,
Starch fluid can not be made thoroughly to be gelatinized.
The content of the invention
The technical problem to be solved in the present invention is：Overcome deficiency in the prior art good there is provided a kind of cooking effect, improve
The continuous steamer of safety coefficient.
The technical solution adopted for the present invention to solve the technical problems is：A kind of continuous steamer, with wood chip and boiling
Pot, the lower end of described chip bin, which is set, is connected with wood chip feeder, and wood chip feeder is connected with high pressure feeder, high pressure feed
Device is connected with digester, is connected with digester at cooking liquor import, and described digester is divided into soak band, heating zone, boiling
Area and scrubbing section and cooling zone, the bottom of digester are provided with pipeline and are connected with spraying pot.
The beneficial effects of the invention are as follows：The present invention is simple in construction, and easy to use, dehydrating effect is good, feeder blade mass dryness fraction
Greatly, screw feed skidding is not easily caused and regurgitates failure, continuous production and person equipment safety is improved, and fixed cost input is small, moves
The big consumption of power is small, and cooking effect is good, improves boiling efficiency.
Brief description of the drawings
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
At 1. chip bin in figure, 2. digesters, 3. wood chip feeders, 4. high pressure feeders, 5. cooking liquor imports, 6. spurt
Pot.
Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side
Formula illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of continuous steamer as shown in Figure 1, with chip bin 1 and digester 2, the lower end of described chip bin 1 is set
Put and be connected with wood chip feeder 3, wood chip feeder 3 is connected with high pressure feeder 4, and high pressure feeder 4 is connected with digester 2, steam
Be connected with saucepan 25 at cooking liquor import, 2 points of described digester be soak band, heating zone, cooking zone and scrubbing section and
Cooling zone, the bottom of digester 2 is provided with pipeline and is connected with spraying pot 6.
The technical concepts and features of above-mentioned embodiment only to illustrate the invention, its object is to allow be familiar with technique
Personage can understand present disclosure and be carried out, and it is not intended to limit the scope of the present invention, all according to this hair
The equivalent change or modification that bright Spirit Essence is made, should all cover within the scope of the present invention.
