Description
Technical field
It the utility model is related to a kind of paper pulp process equipment, and in particular to a kind of pulp beating knife combination.
Background technology
Mashing (beating) is also known as beating.It is that the paper pulp fiber to suspend in water is handled using mechanism, makes it have
Adapt to produce required characteristic on a papermaking machine, and produced paper is reached the operating process of prospective quality.
Because paper pulp fiber is very flexible, as be not added with any processing just be used for copy paper, then be difficult to point when shaping on the net
Cloth is uniform, and the paper hardness being ferreted out is very low.In addition, the paper pulp without mashing, still containing unsegregated fibre bundle, these fibre bundles
Stiff, what is had is oversize, and some is too thick, and shortage is necessary to be prescinded and separate, and such as with its copy paper, then products obtained therefrom is loose, porous, table
Face is coarse, intensity is very low, it is impossible to meets requirement.The paper of pulp production by mashing processing, then tissue tight is uniform, by force
Spend larger.
In pulping process, due to the shear action of the blade of beating equipment, cut off fiber.Simultaneously in beating pressure
In the case that larger, concentration is higher, phase mutual friction between fiber, the transversely cutting of fiber will also result in.
Long fibre can improve the structural homogenity and flatness of paper through being appropriately cut off.Generally to cotton pulp, jute pulp etc.
Long stuff, require there is more cut-out in mashing；Softwood pulp (average fiber length is 2~3 millimeters) is being beaten
When, it should be required according to paper physical property, by fibre cutting to necessary degree.Current beater is as shown in Figure 1, electric
Machine 2 is with movable knife rack 1 in the internal rotation of chamber 3, and knife rest 1 is by rotary shaft 12 and is fixed on the cutter 11 of rotary shaft 12 and forms, knife rest 1
Blade 11 carries out cutting strike to the paper pulp in chamber 3 during rotation, and due to rotation at a high speed, the fiber in paper pulp is hit by blade
With cutting and be broken, reach cut-out paper pulp fiber purpose.
The knife rest of above-mentioned beater cuts paper pulp fiber with the banding cutting blade of high-speed rotation, reaches refinement paper pulp fiber
Purpose.Have the following disadvantages in actual use, concrete condition is as described below：
Because the paper pulp fiber in paper pulp is hit by the blade of high speed, there are two kinds of possibility that fiber is disconnected, one is
The strike of high speed causes fibrous fracture, and one is that the cutting of the knife edge causes fibrous fracture.Two kinds of fracture modes need one jointly
Condition be exactly：The paper pulp fiber being suspended in paper pulp is hit at a high speed by blade, and its essence is exactly paper of the blade relative to suspension
Pulp fibres have high speed.
Referring to the drawings 1, when knife rest 1 rotates at a high speed, under original state, paper pulp be it is static, knife rest 1 rotate after, blade 11
Cutting striking capabilities to static paper pulp are very strong, because knife rest 1 rotates at a high speed and paper pulp is static, the speed difference between them is very
Greatly, therefore blade 11 is very big to the hitting dynamics of paper pulp fiber, and beating resultses are fine.
But after having spent a period of time, paper pulp can be rotated drive by blade 11, paper pulp can flow in the internal rotation of chamber 3, this
When paper pulp and blade 11 between relative velocity will reduce because blade 11 hit to paper pulp fiber speed reduce beating resultses
It can decline.The 30%-50% of blade speed is can reach in the speed that the internal rotation of chamber 3 flows according to detection discovery paper pulp, significantly
The ability of blade attenuated fibers is reduced, reduces the pulping efficiency of beater.
Utility model content
The purpose of this utility model is to provide a kind of pulp beating knife combination, to solve what is mentioned in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of pulp beating knife combination, including base
Seat, three driven gears and a driving gear；Three driven gears engage with driving gear respectively, and three driven tooths
Wheel is equally spaced around driving gear, and driven gear and driving gear are installed in the top of pedestal；In three driven gears
The heart has been respectively fixedly connected with a rotary shaft, and rotary shaft is extended to below pedestal through pedestal, and bearing is provided with pedestal, is rotated
Axle is mounted on bearings；Multiple blades being equally spaced are fixedly connected with same rotary shaft, between any two rotary shaft
Blade be all distributed according to interlaced mode；The distance between no more than two rotary shafts of the length of blade, and be not less than
The half of distance between two rotary shafts.When driving gear rotates, driven gear is driven to rotate, driven gear, which rotates, drives rotation
Axle rotates, and the blade in rotary shaft rotates with rotary shaft.When adjacent rotary shaft rotates, on the position that blade interlocks, two
The staggeredly rotary motion in opposite directions of individual blade, therefore, can be in blade staggered place with the paper pulp of two rotary shaft cutter rotational flows
Head-on converge, this two strands of rotating flows can converge counteracting herein.Therefore, paper pulp will not be further with blade rotational flow.Compare
Paper pulp can improve blade and paper pulp fiber is beaten with the situation of blade high speed rotational flow, the utility model in the prior art
Dynamics and cutting efficiency are hit, improves mashing efficiency.Interlock due to needing blade to be rotated in motion process, the length of blade can not
The half of distance between less than two rotary shafts, it otherwise will not form the situation that blade interlocks；The length of blade can not be more than two
The distance between individual rotary shaft, otherwise blade can cut in rotary shaft.
Preferably, the spacing of the blade in same rotary shaft is 100mm~60mm.Blade arrangement is excessively sparse to be unfavorable for
Efficiently it is beaten；The arrangement of blade is overstocked, and load is excessive when rotary shaft rotates, and Energy Efficiency Ratio is not high.Blade in rotary shaft
Spacing for 100mm~60mm be Energy Efficiency Ratio is higher and can quickly be beaten blade arrangement.
Preferably, blade uses wolfram steel material.Blade is prone to wear out in use, using wear-resisting wolfram steel, can be kept
The knife edge it is sharp, blade is not easy to wear.
Preferably, the thickness of blade is not higher than 15 ° in 5mm~10mm, the blade basil of blade.Blade is blocked up, during rotation
Resistance is larger, it is excessively thin if rigidity of structure deficiency, therefore the thickness of blade can keep less resistance, together in 5mm~10mm
When can also holding structure rigidity.The blade basil of blade can ensure the sharp of blade not higher than 15 °, while can also reduce and cut
Cut resistance.
To sum up, the utility model compared with the prior art the advantages of it is as follows：
(1) the utility model can avoid the phenomenon that paper pulp rotates at a high speed with blade in the prior art, can significantly carry
Cutting of the high blade to paper pulp fiber in paper pulp and effect is smashed, improve pulping efficiency.
(2) blade connection and reasonable arrangement, higher Energy Efficiency Ratio can be ensured, while blade is wear-resistant.
