Product Description
KPF closeddeinkingmachine
1. Overview
KPF-type flotation deinking tank is used mainly for the production of waste paper deinking to remove the ink particles in the slurry, gooey and fillers, thereby to obtain high pulp cleanliness, whiteness pulp material.The operation of the optimal concentration is from 1% to 2%, by a concentration of 2 to 5% of full deaeration tailings are excluded from the system, and it can greatly save energy, reduce the amount of chemicals.
The flotation tank is totally enclosed cylindrical vertical structure, internal section can be divided into 3 to 5 layers, the bottom of each layer has a smaller gap between the clapboard and clapboard.. When it works , the pulp of 1-1.2% concentration by the ejector is pumped to the feeding chamber of a primary flotation .(uppermost layer) The unique design of the ejector is able to self-breathing air and ensure that the high-quality mixing of air and pulp , forming a large number of foams to have a effective adsorption of ink particles. Thus, in a continuous work process, the pulp overflows weir plate into a good pulp chamber, the bubble is to float to the uppermost of the tank body. The good pulp of a primary flotation is pumped into feeding chamber of the next flotation to further processing. So different –level flotation repeat the above process, the good pulp of the last flotation (located in the groove of the lowermost layer) can enter into the design to the head box of flotation tank. The pulp flows from the head box to the next processing system under the gravity. The head box can ensure that the entire tank is filled and has a certain low pressure. The feed room structure of different flotation can make the foam progressively rise to the top of the flotation tank. The foam can be collected by ink ,pulp room, then rowing out from the bottom of the tank through the ink tube.
As shown in figure II
Under normal circumstances, each grade flotation should add 50% of the amount of air to enter the different level flotation air which can rise through the whole groove, so that the bubble density of the groove can increase progressively increases , in order to better collecting and removing the ink and other particles. The low pressure of the ink through the groove interior 0.02 ~ 0.035Mpa is discharged from the bottom of the ink cartridge of the flotation cells, while through the ink of the control valve, the gas can be degassing. The height of the foam layer can be controlled by the degree of opening of the ink control valve , this can make the fibers to achieve a minimum degree, so that the fiber losses and good quality can achieve a good circumstance.
