Abstract
The invention discloses mechanical equipment for collecting secondary fiber of paper pulp and separating water, ink and sludge. A frame consists of three parts which are interlinked; a motor drives a paper pulp separation barrel through a belt to continuously rotate to separate the paper pulp fiber from the water, the ink and the sludge; the paper pulp fiber passes through a collector, while the discharged water, the ink and the sludge pass through another collector below the separation barrel; through a water tank outlet, the paper pulp fiber enters a second part for secondary fiber collection; short fiber in the water, the ink and the sludge collected by the collector which is mounted below the paper pulp separation barrel enters a short fiber collection device through a discharging port; in the short fiber collection device, a worm gear gearbox is driven by the motor; the gearbox drives a stainless steel screen belt through a chain pitch wheel, wherein the two ends of the stainless steel screen belt are respectively provided with a roller; the screen belt continuously and cyclically rotates to fully filter and collect the short fiber in the water, the ink and the sludge flowing onto the screen belt; the bottom of a water tank is internally divided into two parts; the water tank is provided with an ink collection scraping plate inside; and the sludge is drained through a drain for recycling after the water gets clear.
Description
Technical field
The present invention relates to a kind of collecting secondary fiber of paper pulp and water.Printing ink.The machinery that mud separates.
Background technology
Along with economic development, social progress, people increase sharply to the demand of paper and paper products, because China's Forest Resources scarcity, so the recycling of waste paper seems particularly important to China's sustainable economic development, what particularly waste paper utilization brought reduces investment outlay, and the advantage of aspect such as reduce cost has created huge motive force for waste paper regenerated utilization, but people reproduce a large amount of waste water that produced to waste paper simultaneously.Printing ink.Pollution on the environments such as mud toxic substance have produced huge negative effect to society, make China's economic development pay huge cost.Though adopt multiple washing facility both at home and abroad, as vacuum pulp washing machine.The pressure wash engine.Press masters etc. remove the batch (-type) washing facility because production efficiency is low.Take up an area of big.Outside shortcomings such as fiber loss is big are tending towards being eliminated, continous mode rinsing maching development in recent years is very fast, detersive efficiency improves, but which kind of rinsing maching no matter, its operation principle all is a filter process, they can only collect in the low slurry than long fiber, and can't can not collect staple fibre in the paper pulp in other words simultaneously, so recycle in the paper pulp fiber loss late all more than 20% at waste paper.At above-mentioned situation, reach maximization if waste paper can be recycled paper pulp fiber by certain machinery through the paper pulp of chemical treatment, simultaneously with printing ink.The mud recycling utilizes making beating again with waste water, reaches zero-emission, and this will be that a kind of revolutionary change will change present paper-making industry at one stroke to paper-making industry, because pulp-water.Printing ink.The serious environmental pollution that the discharging of mud causes promotes the well-being of mankind.Simultaneously to China and human immeasurable society and the economic benefit of producing.
Summary of the invention
The collecting secondary fiber of paper pulp and the water that provide at domestic no this item technology still is provided.Printing ink.The machinery that mud separates.
For achieving the above object, the present invention has taked following technical scheme to realize.
The present invention relates to the machinery that a kind of collecting secondary fiber and aqueous ink mud separate
