Abstract
An auxiliary dehydrating devices for improving the dehydrating efficiency of a vacuum wash hollander. The device comprises revolving dehydrating net, guiding roller, dehydrating squeegee, collecting reservoir and vacuum dehydrating tank. The device could be installed upon the mesh cage of the vacuum wash hollander and be adjacent to the outlet for sizing agents. The revolving dehydrating net has a portion to engage with the outer arch of the mesh cage of the vacuum wash hollander. The paper sizing agent is dehydrated between two mesh. The dehydrating squeegee scrapes off the water film on the revolving net, and guides water into the collecting reservoir. The collecting reservoir collects filtrated water from dehydrating squeegee. The vacuum dehydrating tank dehydrates deeply the sizing agent. In the manner, the concentration of sizing agent dehydrated by the device increases greatly.
Description
Technical field
It is supporting to the present invention relates to a kind of and vacuum pulp washing machine, in order to the auxiliary dehydrating plant of the dehydration rate that improves vacuum pulp washing machine.
Background technology
In pulp and paper industry, vacuum pulp washing machine is to use visual plant the most widely, and its dewatering efficiency is the important indicator of vacuum pulp washing machine performance.The slurry outlet concentration of vacuum pulp washing machine is to weigh the basic parameter of dewatering efficiency, and slurry outlet concentration is high more, and it is many more to remove the amount of wanting washes, and slurry is washed totally more, and just the wash degree of vacuum pulp washing machine is high more, and dewatering efficiency is high more.
Traditional vacuum pulp washing machine is one and by the round cylinder mould that is partially immersed in the inner vacuum that can rotate continuously in the vat paper pulp that enters in the vat is carried out filtering means dehydration, reaches the purpose that improves pulp density.Under the vacuum action in cylinder mould, the diluted pulp that enters from the vacuum pulp washing machine outside the vat forms pulp layer at the cylinder mould outer surface filtering means dehydration of submergence part, along with the continuous thickening of rotation pulp layer of cylinder mould and expose diluted pulp liquid level in the vat.The cylinder mould (6) of the vacuum pulp washing machine described in accompanying drawing 1 is meant the part of the vacuum dehydration cylinder mould of non-submergence part, the pulp layer that exposes continues dehydration at the cylinder mould outer surface of non-submergence part, pulp material (7) after dehydration is discharged from the vacuum pulp washing machine outlet, finishes the dewatering of pulp overall process.
The slurry outlet concentration of traditional vacuum pulp washing machine generally is 8-10%, and the slurry outlet concentration of forcing to strengthen vacuum is difficult to further improve at 10-12% again.
Summary of the invention
The invention provides a kind of and the supporting auxiliary dehydrating plant of vacuum pulp washing machine, in order to improve the dewatering efficiency of vacuum pulp washing machine.
Whole auxiliary dehydrating plant provided by the present invention has a style of one's own, can arrange outside the top and the cylinder mould near slurry outlet one side of the cylinder mould that is installed in vacuum pulp washing machine, by the revolution dewatering net, in order to support and to make the revolution dewatering net produce the guide roller of continuous rotary motion, and dehydration scraper blade, collecting tank and vaccum dewatering box consists of, the revolution dewatering net has the mating part that coincide that forms the face veneer with the outer circle cambered surface of vacuum pulp washing machine cylinder mould, dehydration scraper blade, collection tank and vaccum dewatering box are arranged on the inboard of the cylinder mould mating part wire side of this revolution dewatering net and vacuum pulp washing machine, dehydration scraper blade has a side to be fixed by the axle center, its opposite side contacts with wire side and can freely swing, the collection tank is positioned at the below of dehydration scraper blade, and vaccum dewatering box and wire side are fitted and can be made elastic displacement along the axis direction of vacuum pulp washing machine cylinder mould.
Described guide roller guide roller consists of by being no less than two (two or more), wherein has one can be equipped with transmission device, moves consistent so that its rotating speed guarantees the revolution dewatering net with the cylinder mould of vacuum pulp washing machine.
The auxiliary dehydrating plant of this vacuum wash engine, its revolution dewatering net is made of wire netting or synthetic resin net, cooperates with the cylinder mould of vacuum pulp washing machine to form the pulp material double dewatering; Guide roller guarantees that the revolution dewatering net cooperates the cylinder mould of vacuum pulp washing machine to produce the continuous rotary motion, guide roller can consist of by being no less than two (two or more), wherein there is one can be equipped with transmission device, moves consistent so that its rotating speed guarantees the revolution dewatering net with the cylinder mould of vacuum pulp washing machine; Dehydration scraper blade is to be made of wear-resisting plate material, and the plate face keeps being not less than the angles of inclination of 5 degree, the moisture film that forms at the revolution wire side to wipe slurries filtration water off, and moisture film water is inducted into the collection tank; The effect of collecting tank is to collect the filtered water that dehydration scraper blade imports, and concentrates and discharge; Vaccum dewatering box is after the dehydration scraper blade dehydration slurry to be carried out deep dehydration.To greatly improve through the slurry outlet concentration after the auxiliary dehydration of this device.
Additional auxiliary dehydrating plant of the present invention on the cylinder mould of traditional vacuum pulp washing machine, the slurry outlet concentration of vacuum pulp washing machine can be brought up to 15-20%, improves the dewatering efficiency of vacuum pulp washing machine greatly.
Description of drawings
Fig. 1 is the structural representation of this vacuum wash engine auxiliary dehydrating plant.
The specific embodiment
In this vacuum wash engine auxiliary dehydrating plant embodiment, whole auxiliary dehydrating plant is installed in top and the close slurry outlet cylinder mould outside on one side of the cylinder mould 6 of vacuum pulp washing machine.Revolution dewatering net 1, adopt nylon polyester net, support and cooperate the cylinder mould 6 generation continuous rotary motions of vacuum pulp washing machine by 3 guide rollers 2, revolution dewatering net 1 is to be designed to coincideing of face veneer according to the outer circle arc shape of cylinder mould 6 with the mating part of the cylinder mould 6 of vacuum pulp washing machine, pulp material is sandwiched between two wire sides and dewaters, revolution dewatering net 1 can be regulated the degree of tightness of turning round dewatering net 1 with the relative distance of other roller by a roller of regulating in 3 guide rollers 2 with the cooperate degree of cylinder mould 6, varied in thickness according to pulp layer 7 is produced freely cooperate.Be provided with 33,1 of dehydration scraper plates in the inboard of revolution dehydration net 1 and collect tank 4 and 1 vaccum dewatering box 5.Dehydration scraper blade 3 is freely with the side that contact of wire side of revolution dewatering net 1, and opposite side is that the axle center is fixing, and dehydration scraper blade 3 is lower in gravity (or applied force) effect, the freely side oscillation that can fix with the axle center of a side and with to contact wire side identical; Collect tank 4 and link to each other with the 3rd dehydration scraper blade, the filtered water that imports in order to collect dehydration scraper blade, and concentrate and discharge; Vaccum dewatering box 5 is can be along the axis direction resilient movement of cylinder mould 6, can produce displacement with the size variation of vacuum, and vaccum dewatering box 5 and the inboard wire side formation face of revolution dewatering net 1 are fitted.
When starting this auxiliary dehydrating plant fully, slurry outlet concentration can reach 18-20% (size of concentration and vacuum and the sealing property of vacuum tank contact-making surface are relevant).
