Description

Spray quick-fried pulping device continuously

Technical field

The utility model relates to the quick-fried pulping device of a kind of continuous spray, and it is applicable to technical process such as paper-making pulping, tobacco leaf processing, feed processing.

Background technology

Industries such as present paper-making pulping, tobacco leaf processing, feed processing, especially paper-making pulping industry, the quick-fried equipment of used spray all is andnon-continuous operation manner, and the commercial scale that adopts present steam-explosion device production paper pulp does not satisfy the wilderness demand of paper industry far away generally all at ton.Paper industry is one of important industry of Chinese national economy, and China is consumption of the second largest paper of our times and big producing country, also is maximum in the world non-wood pulp producing country man.Therefore, though the steam-explosion pulping technique has environment friendly and pollution-free advantage, its device exists the low defective of production capacity to remain the bottleneck problem of paper industry development.

Summary of the invention

The purpose of this utility model provides a kind of practicality, energy-conservation, the inexpensive quick-fried pulping device of continuous spray just in order to overcome existing weak point in the above-mentioned prior art.

The quick-fried pulping device of continuous spray of the present utility model is to spray quick-fried device by two-stage at least to be composed in series; Wherein the first order is sprayed quick-fried device and is included in its upper cover crown center position and is provided with feed pipe, be provided with the tank body of discharge nozzle in its low head bottom, the inner chamber of this tank body is divided into material splendid attire cavity that is connected with feed pipe and the sandwich-type vapor chamber that is made of jointly inner tank wall and inner barrel outer wall by the inner barrel that is arranged in the tank inner chamber, be processed with the through hole of some connection sandwich-type vapor chamber and cavity on the barrel of described inner barrel, the lower end of this inner barrel is a funnel-shaped structure, and the outlet of its bucket bottom is provided with discharge nozzle and is connected bottom low head; The upper port of described inner barrel is the toroidal structure, and its edge mouth and inner tank wall Joint; The tank skin of tank body is provided with steam or the compressed air inlet pipe that is communicated with the sandwich-type vapor chamber; It is to be made of a tank body that seals that quick-fried device is sprayed in the second level, is provided with the discharging opening pipe in the low head bottom of tank body, is provided with the charging mouth of pipe at the upper cover crown center position of tank body, and tank skin is provided with steam or compressed air inlet pipe and pressure gauge connection pipe.

Operation principle of the present utility model is as follows:

Raw material of papermaking fiber such as wheat stalk, under certain saturated vapor effect, fiber is by water vapour institute swollen, and cellulose crystallity improves, be full of steam in the hole, lignin is softening under the high temperature, the degraded of half pars fibrosa, thus weakened interfibrous connection, when the material that is full of certain pressure reduces pressure suddenly, because the rapid expansion of medium is dissociated fiber, produce " explosion " effect.At different pulping raw materials,, can make qualified paper pulp by controlling certain technological parameter.

The pure water steam explosion pulping paper technology that the utility model adopts is the significant improvement to traditional pulp and paper technology, be medium with the saturated vapor in its pulping process, material " boiling " environmental protection does not produce black liquor, this technical equipment, not only be used for paper industry, can also be used for industries such as feed, alcohol, food, chemical industry.

When adopting device of the present utility model to carry out slurrying, continuously the material of pulverizing is got into the first order by charge door by feed screw and spray (material splendid attire cavity) in the quick-fried device cylindrical shell, sandwich-type vapor chamber inside and outside water vapour or compressed air feed via steam inlet between the cylindrical shell, and the through hole of some connection sandwich-type vapor chamber that process on the barrel by inner barrel and cavity is the material heating, along with temperature, the rising of pressure, material is swelling gradually, the semi-finished product spirt second level is sprayed in the quick-fried device tank body by bottom material outlet and connecting pipeline by the pressure in the tank body; Meanwhile, water vapour or compressed air spray quick-fried device tank skin by the second level and are provided with steam or compressed air inlet pipe additional steam or compressed air in quick-fried device is sprayed in the second level, and after pressure maintained certain level, finished product sprayed from lower part outlet.Whole process of production keeps continuous feed, and two-stage is sprayed quick-fried device and replaced input and output material, thereby realizes the serialization that slurrying is produced.

The utlity model has following beneficial effect:

1. continuous feed, two-stage are sprayed quick-fried device and are replaced input and output material, have realized the serialization that slurrying is produced, thereby the quick-fried pulping technology for paper-making industrialization of green spray is become a reality.

2. owing to realized serialization, production capacity increases substantially, and therefore, cost of investment reduces greatly.

3. because serialization charging, spray are quick-fried, and steam pressure maintains relatively stable level in the jetting and bursting cylinder, and steam thermal energy is utilized continuously, therefore, this device energy-saving effect highly significant.
