Abstract
The utility model discloses a kind of taper pulp distributor, comprise the transition conduit be connected with stock inlet, transition conduit is connected with taper house steward, the other end of taper house steward is connected with reflux, described taper house steward is made up of antetheca, rear wall and upper and lower two sidewalls, antetheca is evenly provided with some cloth be communicated with taper house steward and starches arm, rear wall is made up of the arc and the straight plate be connected between arc and reflux being connected to transition conduit, and described arc is inner concave shape arc.The utility model improves the efficiency of pulp distributor, cloth is starched more even, thus improves papermaking quality.
Description
Technical field
The utility model relates to the cloth slurry equipment in head box, is specifically related to a kind of taper pulp distributor, is uniformly distributed into the device in pond, head box weir by online paper pulp along net overall with.
Background technology
Pulp distributor is the inlet port of head box, and high efficiency pulp distributor makes paper pulp can obtain uniform distribution once entering paper machine.And the requirement of pulp distributor efficiently ensures that paper pulp can form stable equipressure distribution along paper machine full width is wide.The pressure distribution of slurry stream in Taper Pipe is subject to the impact of three principal elements: pressure recover, friction loss and the loss in head caused by aperture effect.The pulp distributing device with taper pipe that current production uses, particularly with the Taper Pipe sectional dimension of the rectangle pulp distributing device with taper pipe of orifice plate be by Bai Nasi equation calculate after again unit be made into linear cross-section varibility to manufacture.The straight line method of substitution can cause the change of the slurry stream pressure head along pipe range.
Utility model content
The purpose of this utility model is to provide a kind of taper pulp distributor, and to overcome the defect that above-mentioned prior art exists, the utility model improves the efficiency of pulp distributor, cloth is starched more even, thus improves papermaking quality.
For achieving the above object, the utility model adopts following technical scheme:
A kind of taper pulp distributor, comprise the transition conduit be connected with stock inlet, transition conduit is connected with taper house steward, the other end of taper house steward is connected with reflux, described taper house steward is made up of antetheca, rear wall and upper and lower two sidewalls, antetheca is evenly provided with some cloth be communicated with taper house steward and starches arm, rear wall is made up of the arc and the straight plate be connected between arc and reflux being connected to transition conduit, and described arc is inner concave shape arc.
Further, the bottom of taper house steward is provided with and can makes its inclined support, and arrange cloth slurry arm lopsidedness upwards.
Further, the angle between taper house steward and horizontal plane is 45 ° ~ 60 °.
Further, the radian of arc is 0.785rad ~ 3.14rad.
Further, the line at the center of cloth slurry arm forms some parallelogram.
Compared with prior art, the utility model has following useful technique effect:
The structure of taper house steward rear wall of the present utility model is not the linear structure in traditional sense in the straight line method of substitution, but in the linear beginning of taper house steward, reduce the difference in height between rear wall and antetheca, linear structure is become curvilinear structures, start-up portion by rear wall is designed to the arc of inner concave shape, from Bernoulli equation, the pressure of slurry stream when entering this segment structure diminishes, namely diminish with the pressure differential of transitional pipe section, thus the flow regime in taper house steward is relaxed relatively, such improvement simultaneously is also unfavorable for the generation of corner's whirlpool, pressure and energy loss are reduced, outlet pressure distribution also can be more even.
Further, the radian of arc is rationally set, effectively can reduces the generation of whirlpool and the loss of energy.
Further, the line at the center of cloth slurry arm forms some parallelogram, and the arrangement of cloth slurry arm parallelogram, and the slurry through cloth slurry arm can be made more even.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model;
Fig. 2 is right view of the present utility model;
Fig. 3 is the A-A direction view of Fig. 2.
Wherein, 1, transition conduit; 2, taper house steward; 3, cloth slurry arm; 4, reflux; 5, support.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
See Fig. 1 to Fig. 3, a kind of taper pulp distributor, comprise the transition conduit 1 be connected with stock inlet, transition conduit 1 is connected with taper house steward 2, the other end of taper house steward 2 is connected with reflux 4, described taper house steward 2 is by antetheca, rear wall and upper and lower two sidewalls composition, antetheca is evenly provided with some cloth be communicated with taper house steward 2 and starches arm 3, rear wall is made up of the arc and the straight plate be connected between arc and reflux 4 being connected to transition conduit 1, described arc is inner concave shape arc, the radian of arc is 45 ° ~ 60 °, the bottom of taper house steward 2 is provided with the support 5 that it can be made inclined, and arrange cloth slurry arm 3 lopsidedness upwards, angle between taper house steward 2 and horizontal plane is 0.785rad ~ 3.14rad.
Below implementation process of the present utility model is described in further detail:
The slurry come from starching pump passes through transition conduit 1, rear wall along taper house steward 2 flows into, flow out from cloth slurry arm 3 and reflux 4 respectively again, due to the existence of the loss in head that the pressure loss, friction loss and aperture effect cause, linear sectional dimension can impact the distribution of pressure and speed, in order to reduce friction loss and the pressure loss, the beginning part circular arc of the linearly connected between transition conduit 1 and taper house steward 2 is replaced, make cloth starch the port of export sectional pressure distribution of arm 3 more evenly, improve papermaking quality.It is excessive that slurry carries out secondary by arc in taper house steward 2, the loss of whirlpool generation and energy is reduced, thus make the pressure distribution in cloth slurry arm 3 exit more even, slurry flows through starching pump and flows into taper house steward from transition conduit, flowed out from cloth slurry element and reflux end by taper house steward, the quantity of reflux of reflux is 10% of entrance total amount.
