Abstract
The utility model relates to a wax liquid directly applying device for fiber boards with an aluminum sulfate solution tank. The utility model is characterized in that the device is composed of a paraffin wax melting pot, a wax vapor pipe and an aluminum sulfate solution tank. A vapor inlet pipe is connected with one end of the wax vapor pipe through the paraffin wax melting pot, and a wax spraying device on the other end of the wax vapor pipe sprays wax towards the wood sheet feeding port of a defibrator. The device of the utility model has the advantages of no electricity consumption, no need of water, no need of emulsifier, no pollution, convenient operation and use, strong applicability and low manufacturing cost.
Description
The utility model relates to soft, hard and medium density fibre board (MDF) production technical field, the specifically straight wax liquid device of fiberboard of wet method, dry method.
In Fibreboard Production, need to add the paraffin that accounts for bone dry fiber weight about 1.5%, make it possess certain water resistance.The applying wax method that adopts is that paraffin wax emulsions applies method at present, as shown in Figure 1, with emulsifying agent (ammonium oleate, Tea Saponin, breast lark etc.) and paraffin molten paraffin emulsion reaction pot (1) in after the abundant stirring, make paraffin wax emulsions, again after paraffin wax emulsions dilution bucket (2) is by the water dilution, [the fiber vapour slurry that comes out from defibrator (4) enters stock tank (5) through vapour and pulp separating device to put into the fibre stuff of continuous size vat (3), (6), then in the suction continuous size vat], by precipitating reagent (aluminum sulfate solution) the paraffin wax emulsions breakdown of emulsion is deposited on the fiber surface at last.This applying wax method can make fiberboard obtain favorable waterproof property, but cost is higher, calculate (is example with the ammonium oil emulsifier) to produce 4500 cubic metres of fiberboards per year, need 12.8 tons of consumption ammonium oleates, 12 tons of ammoniacal liquor, electric 3000 remainings, 1200 tons in clear water, amount to surplus the RMB 70,000 yuan, and operation inconvenience, contaminated environment.
The purpose of this utility model is, provides a kind of and can overcome above-mentioned shortcoming, can fully guarantee the straight wax liquid device of fiberboard of fiberboard water resistance again.
The technical solution of the utility model is: this device is made up of melted paraffin wax pot, aluminum sulfate solution jar and wax steam pipe.An end that has a steam inlet pipe to pass melted paraffin wax pot and wax steam pipe links, the wax sprayer of the wax steam pipe other end is facing to the defibrator chip feed, wax steam pipe road is made up of wax conveying tube and steam transmitting pipe, the precious residual steam that the fiberboard hot press is discharged is after air inlet pipe adds, enter steam transmitting pipe in the wax steam pipe until wax sprayer through the melted paraffin wax pot, discharge from gland steam exhauster then, thereby make steam the part temperature of process all remain on 80-90 ℃, the solid paraffin that has melted in the melted paraffin wax pot is just uniform and stable with the form of liquation, flow to wax sprayer (even under the condition of subzero 40 ℃ of weathers also can so) by deadweight unblockedly.Behind the valve opening, wax sprayer sprays to paraffin as vaporific on the wood chip surface in the defibrator charging aperture.Be sprayed at the lip-deep paraffin of bone dry fiber weight about 1.2% that accounts for of wood chip in wood chip is pushed into defibrator, under when defibrator moves, acting in original pressure (0.98-1.27MPa), temperature (180-190 ℃) and the centrifugal force (the defibrator speed of grinding plate is 900r/min), combined processes such as paraffin process spreading wetting, immersion, dispersion, the absorption of single polymolecular, infiltration and this element are bonding are kept on wood-fibred with the form of particulate at last.This fiber is discharged by the defibrator blow-off valve, and after vapour and pulp separating device entered stock tank, partly desorption had been deposited on the wood-fibred surface under the effect of precipitating reagent (aluminum sulfate solution) again in the lip-deep paraffin particulate of wood-fibred.
Not power consumption of device of the present utility model, water does not need emulsifying agent, and pollution-free, easy for operation, applicability is strong, low cost of manufacture (only 500 yuan of package unit manufacturing, mounting costs), durable in use, the fiberboard water resistance can be up to state standards fully.
