Abstract
Disclosed is a waveform flow passage head box with wide suitable driving speed range (80-800m/min), big concentration range (zero point five to one point eight percent), variety in runnability, good homogenate effect, small size of box body and high efficiency. A pulp inlet has a pulp-in square cone pipe and a step orifice plate, the bottom part of the utility model is provided with a base seat, the box body is equipped with an overflow chamber and an air chamber as well as a front lateral plate and a rear lateral plate, a spraying port has an upper labial lamina adjusting mechanism, an upper labial lamina, an erecting small labial lamina and a lower labial lamina, and the upper and the lower labial laminas form a nozzle. The structure is characterized in that a narrow flow passage inclining upward is arranged between the step orifice plate and the nozzle, and the wall of the flow passage is provided with a waveform leveling element. The utility model is used for paper machines in the paper industry.
Description
Technical field
The utility model relates to a mortar distributor of paper machine, especially a kind of waveform channel head box.Be applicable to the paper industry paper machine.
Background technology
Head box is as a mortar distributor of paper machine, and its effect is that the wet end to paper machine provides full width homodisperse slurry stream.Therefore require head box to guarantee the isobaric constant speed of full width slurry stream on the one hand, also need to make slurry stream to be in the microturbulent motion state on the other hand, disperse, the slurry stream of ejection is evenly distributed to guarantee slurry suspension.The homogenate way that present domestic head box makes the slurry miscarriage give birth to microturbulent motion mainly contains two kinds, and a kind of is flashboard group homogenate device, and as shown in Figure 2, its homogenate mechanism is that the contraction diffusion that slurry flows by plate group slit makes slurry produce tubulence energy, and this apparatus structure is simple.Shortcoming is that the casing volume is big, and slurry stream Turbulent Scales is low, and slurry homogenate weak effect is so can only be used for the low speed of a motor vehicle (below 100 meters/minute).Another kind is a rotation hole roller homogenate device, and as shown in Figure 3, its homogenate mechanism is that the contraction diffusion that slurry flows by the turnover aperture makes slurry produce turbulence, at present domestic more generally use.This apparatus structure is simple, and slurry stream Turbulent Scales is medium, and the homogenate effect is better, can adapt to the medium speed of a motor vehicle (120-400 rice/minute).Because roller surfaces, make stock pump go into air when shortcoming is the low speed of a motor vehicle,, and use the head box tank-volumes of a plurality of (more than two) doctor-roll bigger so should not be used for the low speed of a motor vehicle, the slurry stream phenomenon of in case, rolling, flow over, wadding is poly-more easily to make slurry.So higher slurry and long fiber of improper concentration.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of adaptation vehicle speed range wide (80-800 rice/minute), concentration range big (0.5-1.8%), the waveform channel head box wide in variety, that homogenate is effective, casing is little, efficient is high of manufacturing paper with pulp are provided.
The technical scheme that the utility model adopted is: the waveform channel head box, stock inlet has into slurry side's Taper Pipe, step orifice plate, base is arranged at the bottom, establish overflow, air chamber and front side plate and back side panel in the casing, mouth spray has top lip of slice guiding mechanism, top lip of slice, upright little labial lamina, aulaeum, labial lamina constitutes nozzle up and down, and its design feature is to be provided with the narrow runner that is tilted between described step orifice plate and the nozzle, and flow path wall is provided with the neat and well spaced element of waveform.
The utility model is shaped on pit on the base at narrow runner end place, it is built-in with doctor-roll.
It is shaped as semicircle the neat and well spaced element of waveform described in the utility model.Also can be triangle, zigzag, trapezoidal.
The beneficial effects of the utility model are: the utility model combines the advantage of flashboard group homogenate device and rotation hole roller homogenate device, on design theory, used narrow runner to carry the new ideas of slurry, and on runner, add fixing waveform turbulence element, replaced the doctor-roll after cloth is starched orifice plate, and make slurry stream in course of conveying, obtain neat and well spaced and produce the poly-microturbulent motion that prevents to wad a quilt with cotton, and, provide good condition for obtaining good horizontal cloth slurry and evenness owing to adopt narrow runner to carry to prevent slurry stream from rolling and flow over.Adapt to concentration range big (0.5-1.8%), it can adapt to dense, the low quantitative paper kind of low slurry, also can adapt to dense, the high quantitative paper kind of high slurry.Adapt to vehicle speed range wide (80-800 rice/minute),, can adapt to lower speed of a motor vehicle requirement owing to adopt at the bottom of the oblique case and the pit type doctor-roll, and can adopt the air cushion pressurization, when using the air cushion pressurization, remove overflow and doctor-roll, 800 meters/minute of car scooters, thus the higher speed of a motor vehicle adapted to.In addition, casing is little in addition, efficient is high, the advantage wide in variety of manufacturing paper with pulp.

Fig. 2 is the structural representation of the utility model background technology flashboard group homogenate device.
Fig. 3 is the structural representation of the utility model background technology rotation hole roller homogenate device.
The specific embodiment
As shown in Figure 1, the head box of present embodiment is located on the base 13, into slurry side's Taper Pipe 1 is arranged at the stock inlet place, its outlet connects step orifice plate 2, the exit of step orifice plate is connected with a narrow runner 3 that is inclined upwardly about 10 degree, be shaped on the neat and well spaced element 4 of semicircular waveform on its flow path wall, the end of narrow runner is shaped on a pit, built-in doctor-roll 5 also can not established doctor-roll, direct and nozzle 12 connections of narrow runner, the below of nozzle is an aulaeum 11, the top is a top lip of slice 9, and the front of top lip of slice is provided with upright microcheilia plate 10, and top lip of slice guiding mechanism 8 also is equipped with on top lip of slice top.Air chamber 7, overflow 6, front side plate 15 and back side panel 16 are arranged in the casing of base 13 tops.But above-mentioned overflow can not established yet, and the narrow runner 3 that the neat and well spaced element 4 of waveform is housed directly links to each other with nozzle 12.The below of aulaeum is a breast roll 14.
The shape of the neat and well spaced element 4 of waveform can also have triangle, zigzag, trapezoidal, also can be other geometry that needs.
The course of work of the present utility model is: slurry stream advances slurry from advancing the side's of slurry Taper Pipe, and step orifice plate cloth slurry from the slurry stream that pulp distributor comes out, is surfed the Net by nozzle ejection behind the narrow runner through the neat and well spaced element of waveform is housed.
