Abstract
The utility model discloses a double-roller squeezing dewatering machine for extracting the black liquor of the paper pulp. Two pressing rollers whose rotary directions are opposite are installed on a machine frame whose upper part is a pulp groove in parallel way; the surface of each pressing roller is wrapped with a small-hole filter plate; the machine frame is provided with scraping plates corresponding to the two pressing rollers; the upper part of the front scraping plate is provided with a water spray pipe; the lower part of the machine frame is provided with a spiral conveyer; the spiral conveyer and the two pressing rollers are respectively driven by a stepless speed regulation electric motor. The utility model has the advantages of good dewatering effect, high extraction rate of black liquor, simple structure of whole machine, less investment, and convenient operation. The utility model is especially suitable for middle and small size papermaking enterprises for which the straw pulp can be used as the raw material.
Description
The utility model relates to the post processing equipment technical field of cellulose pulp, more particularly relates to a kind of Water Extraction Machinery that extracts black liquor.
At present China's paper industry is used to extract the equipment of black liquor and other dehydration procedure, and ubiquity pulp concentration is low, and extraction rate of black liquor is low, and one-time investment is big, not easy operation control, defective such as production capacity is low.The patent No. be 91218775.1 " a kind of Double screw pulp extruder " though improve to some extent, its dependability is poor, has the deficiency of production capacity difference equally.
The purpose of this utility model provides a kind of extraction rate of black liquor height, and operating maintenance is the paper pulp squeezing dewatering machine easily.
The utlity model has frame, the top of frame is stock tank, at preceding pressure roller that the switched in opposite on the frame of being installed in parallel in is arranged above the stock tank and back pressure roller, the surface of two pressure rollers is coated with the aperture filter plate, has groove below the aperture filter plate and the fluid hole of the circle distribution that communicates with groove.Preceding scraper that cooperates with preceding pressure roller and the back scraper that cooperates with the back pressure roller also are installed on frame, and preceding scraper top is equipped with sparge pipe.Conveying worm is installed below frame, and conveying worm is driven by a motor via reducer, and front and back two pressure rollers are driven by another motor via reducer.
The utility model has the advantages that press dewatering is effective, the extraction rate of black liquor height, pulp concentration can reach about 30%, production capacity and concentration can be adjusted easily by regulating motor speed, and to reach optimum state, overall structure is simple and reliable, use easy to maintenance, cost is low, small investment, and being particularly suitable for the straw pulp is the middle-size and small-size papermaking enterprise of raw material.
Fig. 1 is a longitudinal sectional view of the present utility model:
Fig. 2 is a vertical view of the present utility model.
In the embodiment that accompanying drawing provides, the utility model has a good frame 1 of globality, the top of frame 1 is semicircular stock tank, at the preceding pressure roller 4 and the back pressure roller 6 that have above the stock tank on frame of being installed in parallel in 1, two pressure roller switched in opposite are driven by reductor 11 by same stepless speed-regulating motor 12.The surface of two pressure rollers 4,6 all is coated with the aperture filter plate, and the groove of processing on pressure roller and the fluid hole of the circle distribution that communicates with groove are arranged below the filter plate.Preceding scraper 2 that cooperates with preceding pressure roller 4 and the back scraper 5 that cooperates with back pressure roller 6 also are installed on frame 1, and there is the sparge pipe 3 on frame of being installed in 1 preceding scraper 2 tops.The conveying worm 8 that spiral organ is housed in its that communicates with stock tank is installed below frame 1, and conveying worm 8 is driven by reductor by another motor with stepless speed regulation 10.
During work, slurry feeds from the charging aperture 9 on the conveying worm 8, pushed in the frame 1 top stock tank by spiral organ, by being extruded dehydration through out-of-date between preceding pressure roller 4 and the back pressure roller 6, the fluid hole of the black liquor that squeezes out on pressure roller flows in the frame 1, flow out by the black liquid outlet on the frame 17, send to the alkali recycle section.Slurry after the dehydration is scraped from front and back pressure roller 4,6 by front and back scraper 2.5, and scraper 2 is top through out-of-date in the past, by sparge pipe 3 water spray dilutions, flows to next procedure then.
