Abstract
The invention relates to a high-vacuum-degree pulp washer which comprises a vacuum pulp washer. The high-vacuum-degree pulp washer is characterized in that a pipeline which is connected to a pulp pool is installed at a water leg tube and a distribution valve of the vacuum pulp washer; and a vacuum pump and a water tank are installed in sequence on the pipeline. According to the high-vacuum-degree pulp washer provided by the invention, the pipeline is connected with the water leg tube and the distribution valve of the vacuum pulp washer, and the vacuum pump is adopted for suction to form a negative pressure to intensively suck discharged water, so that the water discharge acceleration is enhanced, the vacuum degree of the pulp washer is effectively improved, the capability and the efficiency of the pulp washer are greatly improved, and the beneficial foundation is laid for whitening and low chemical consumption quantity of the pulp. Due to the improvement, the vacuum degree of the pulp washer increases to 0.3MPa from original 0.1MPa, and residual alkali extracted from the pulp is reduced to be less than 1.0g/L from 1.5g/L.
Description
Technical field
The invention belongs to the pulping machinery technical field, specially refer to the improvement of the vacuum system of vacuum pulp washing machine.
Background technology
In the pulping and paper-making industry, vacuum pulp washing machine is the flat valve type at present, the discharge opeing of its rotary drum outlet communicates with the corresponding lattice chamber of drum surface respectively, and wherein spool has sealed section port whole circumference is divided into Liang Da district: region of no pressure and stripping are starched and exhaust area (spool covering part).When rotary drum often circles, each leakage fluid dram is successively by the vacuum filtration district, stripping slurry and exhaust area.Often circle and just realize suction strainer, stripping slurry and exhaust process.The sealing property of distributing valve seal box quality directly affects the vacuum of wash engine, and vacuum is whether good principal element of decision performance, thereby affects the production capacity of wash engine.Therefore keeping well and reach high vacuum is the key of this production efficiency.
Summary of the invention
The object of the present invention is to provide a kind of vacuum of further increase wash engine, thereby improve the condition of high vacuum degree wash engine of wash engine ability and operating efficiency.
The present invention realizes by following technology:
A kind of condition of high vacuum degree wash engine comprises vacuum pulp washing machine, it is characterized in that: at the water leg pipe of described vacuum pulp washing machine and distributing valve place, the pipeline that is connected to stock tank is installed, vavuum pump and water tank are installed on this pipeline successively.
Condition of high vacuum degree wash engine of the present invention is by at the water leg of vacuum pulp washing machine and distributing valve place connecting line, utilize vavuum pump to aspirate, form negative pressure like this and draining is produced strong suction, increased the draining acceleration, effectively increased wash engine vacuum, wash engine ability and efficient have greatly been improved, for bleaching and the chemical industry consumption consumption of slurry have been established favourable basis.By improvement of the present invention, wash engine vacuum is brought up to 0.3MPa by original 0.15MPa, and slurry extracts residual alkali has 1.5g/L to drop to below 1.0g/L.
Description of drawings
Fig. 1 is the structural representation sketch of condition of high vacuum degree wash engine of the present invention.
The specific embodiment
Condition of high vacuum degree wash engine of the present invention is in the water leg pipe of vacuum pulp washing machine and distributing valve 1 place's connecting pipe 2, and vavuum pump 3 and water tank 4 are installed on this pipeline 2 successively, and pipeline 2 finally leads to stock tank 5.
