Abstract
The utility model relates to a novel vacuum pulp washer which comprises a vacuum pulp washer. The novel vacuum pulp washer is characterized in that a pipeline connected with a pulp pool is arranged at a water leg pipe and distribution valves of the vacuum pulp washer; and a vacuum pump and a water tank are sequentially arranged on the pipeline. According to the novel vacuum pulp washer, the pipeline is connected at the water leg pipe and the distribution valves of the vacuum pulp washer, and the vacuum pump is used for sucking, so that the discharged water can be intensively sucked by the negative pressure, the drainage is accelerated, the vacuum degree of the vacuum pulp washer is effectively increased, the capability and the efficiency of the vacuum pulp washer are greatly improved, and good foundation is laid for bleaching of pulp and chemical consumption. Due to the improvement of the novel vacuum pulp washer, the vacuum degree of the pulp washer is increased to 0.3MPa from the original 0.15MPa, and the extract residual alkali of the pulp is reduced to be less than 1.0g/ L from 1.5g/ L.
Description
Technical field
The utility model belongs to the pulping machinery technical field, specially refers 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 purpose of this utility model is to provide a kind of vacuum of further increase wash engine, thereby improves the novel evacuated wash engine of wash engine ability and operating efficiency.
The utility model is realized by following technology:
A kind of novel evacuated 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.
Novel evacuated wash engine of the present utility model 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 utility model, 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 the novel evacuated wash engine of the utility model.
The specific embodiment
The novel evacuated wash engine of the utility model 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.
