Abstract
The utility model relates to an improved decker machine which comprises a decker machine, wherein a waste water buffer tank is connected onto the decker machine through a pipeline; and a draining centrifugal pump is arranged on a water draining pipe of the waste water buffer tank. According to the improved decker machine, a vacuum pulp washing principle is utilized to the decker machine; the waste water buffer tank and the draining centrifugal pump are additionally arranged on an original decker machine and the draining acceleration is increased by using negative pressure formed by sucking of the centrifugal pump, and thus the decker effect is effectively improved, the residual alkali before bleaching is reduced and a favorable foundation for chemical consumption of a bleaching machine for paper-making pulp is laid. According to the detection and due to the adoption of a condensing device disclosed by the utility model, the pulp discharging concentration can be increased by about 35-40 percent.
Description
Technical field
The utility model belongs to the papermaking equipment technical field, particularly relates to a kind of improved decker.
Background technology
In the pulping and paper-making industry; Decker be mainly used in slurry dehydration, concentrate; Its principle one relies on the inside and outside liquid level difference of cylinder mould to carry out, and secondly is to utilize the extruding force between pressure roller and the cylinder mould to dewater, but unsatisfactory on result of use; Its cylinder concentrated effect is poor, and discharging concentration is merely 3-4%.
Summary of the invention
The purpose of the utility model is to overcome the defective of above-mentioned prior art, and providing a kind of can effectively increase concentrated effect, reduces the improved decker of residual alkali before floating, and can discharging concentration be increased to 7-8%.
The utility model is realized through following technical scheme:
A kind of improved decker comprises decker, it is characterized in that on said decker, being connected with the waste water surge tank through pipeline, and the draining centrifugal pump is installed on the outlet pipe of this waste water surge tank.
The improved decker of the utility model uses vacuum pulp washing principle on the decker; Through setting up waste water surge tank and draining centrifugal pump at original decker; The negative pressure of utilizing the suction of centrifugal pump and forming increases the draining acceleration; Thereby effectively increased the cylinder concentrated effect, and reduced float before residual alkali, established favourable basis for the bleaching machine chemical industry of paper making pulp consumes consumption.Through detecting, adopt the enrichment facility of the utility model, pulp concentration can improve about 35-40%.
Description of drawings
Fig. 1 is the concentration flow path sketch map of prior art decker;
Fig. 2 is the structural representation sketch of the improved decker of the utility model.
The specific embodiment
The improved decker of the utility model is the improvement of on the basis of existing decker, carrying out, and promptly on decker 1, connects a waste water surge tank 2 through pipeline 5, and draining centrifugal pump 4 is installed on the outlet pipe 3 of waste water surge tank 2.
After above-mentioned improved decker application, conveying end slurry 25g is diluted to 100g, gets rid of to over dry with centrifuge, and the slurry after the drying multiply by centrifuge and dries coefficient, then divided by 25g, obtains pulp concentration machine raising degree.Experiment shows, use this device after, pulp concentration can improve 35-40%.
