Description

A kind of fourdrinier wire machine conveyer trough of manufacturing paper with pulp

Technical field

The utility model relates to a kind of conveyer trough, particularly a kind of fourdrinier wire machine conveyer trough of manufacturing paper with pulp.

Background technology

As the important component part of purifying vehicle exhaust technology, three-way catalytic converter plays crucial effect in whole exhaust gas purification system.The three-way catalytic converter structure is made up of housing, liner, carrier three parts: housing is generally made by stainless steel, in case cause the obstruction of catalyst because of oxide skin comes off; Carrier is generally the noble metal cordierite thin wall honeycomb ceramic that is coated with platinum, rhodium, palladium, and purpose provides the high surface of tail gas conversion and the cleanser adhesion layer of conversion, reaches the purpose of cleaning of off-gas; Liner then is the ceramic sealing layer that is between the two, is bringing into play the multiple action of fixing, sealing, heat insulation, noise reduction, damping.

Three-way catalytic converter becomes crucial part in the automobile tail gas purification system by above three parts are effectively encapsulated combination.For encapsulation process, the uniformity of liner thickness and grammes per square metre on all directions helps the efficient and the quality of ternary catalyzing unit encapsulation; To ternary catalyzing unit in use, liner behind the expanded by heating has certain dilatancy, the power that produces after expanding has support and fastening effect to carrier and housing, and all even uniformity of expansive force also depends on the liner uniformity on thickness and grammes per square metre in process of production.After liner a certain position thickness and grammes per square metre occurring and exceeding standard, the fastening force that liner provided will want high with respect to standard value herein, thereby the back pressure that carrier is produced also will improve.Because carrier is cellular loose structure, the pressure that self institute can bear is limited, and after surpassing its maximum pressure that bears, carrier very likely occurs rupturing or the situation of fragmentation, thereby causes the inefficacy of whole ternary catalyzing unit.

As shown in Figure 1, the conventional flow stock tank comprises slag-drip opening 1, stock inlet 2, first-class slurry chamber 3, the second stream slurry chamber 4, flashboard 5, the 3rd stream slurry chamber 6, first doctor-roll 7, fourdrinier wire 8.The problem that prior art exists mainly is in the liner production process, and the even institute of starching mass flow discrepancy causes, and the basic reason of this phenomenon is that the fourdrinier wire unreasonable starching mass flow discrepancy that causes of machine flow channel design of manufacturing paper with pulp causes.

Summary of the invention

The utility model provides a kind of fourdrinier wire machine conveyer trough of manufacturing paper with pulp to solve prior art stream slurry and measure uneven problem.

The technical solution of the utility model is as follows;

A kind of fourdrinier wire machine conveyer trough of manufacturing paper with pulp, its structure comprise that slag-drip opening, stock inlet, first-class slurry chamber, the second stream slurry chamber, flashboard, the 3rd stream slurry chamber, first doctor-roll, fourdrinier wire form; Described conveyer trough also comprises second doctor-roll and the 4th stream slurry chamber; It is indoor that described second doctor-roll is arranged on the described second stream slurry, and described the 4th stream slurry chamber is arranged between described second stream slurry chamber and the 3rd stream slurry chamber, and described flashboard is placed between described the 4th stream slurry chamber and the second stream slurry chamber.

The technique effect that technique scheme reaches is as follows;

The utility model is by the improvement of machine conveyer trough that fourdrinier wire is manufactured paper with pulp, and emphasis is that traditional conveyer trough is improved, and by increasing the capacity of flow channel, the flow dispersion degree that increases exterior mechanical stirring and increase slurries changes the purpose of improving that reaches final.Thereby effectively control the flow of starching, it is reached unanimity on all directions of starching, guarantee the quality of liner end product, thereby solve the difference on liner thickness and the grammes per square metre direction.

Description of drawings

Further specify the utility model below in conjunction with the drawings and specific embodiments.

Fig. 1 is the structural representation of conventional flow stock tank.

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 2, a kind of fourdrinier wire of the utility model its structure of machine conveyer trough of manufacturing paper with pulp comprises slag-drip opening 100, stock inlet 101, first-class slurry chamber 102, the second stream slurry chamber 103, second doctor-roll 104, flashboard 105, the 4th stream slurry chamber 106, first doctor-roll 107, the 3rd stream slurry chamber 108, and fourdrinier wire 109 is formed.

The utility model conveyer trough second doctor-roll 104 is placed in the second stream slurry chamber 103, and second doctor-roll 104 is used for the horizontal stirring of slurries, helps the dispersion of slurries.

Flashboard 105 is placed between the 4th stream slurry chamber 106 and the second stream slurry chamber 103., flashboard 105 is used to control the stream slurry of slurries, and the slurries of big flow are partly stopped backflow, changes slurry direction, and can play the effect of deceleration current stabilization.

Simultaneously, the 4th stream slurry chamber 106 is arranged between the second stream slurry chamber 106 and the 3rd stream slurry chamber 108, first baffle plate 200 in the second baffle stream slurry chambers 103 201 to the second in the 3rd stream slurry chamber 108 is low, and it helps flowing forward of slurries, and baffle plate plays the effect of deceleration current stabilization herein.

The utility model conveyer trough can adopt stainless steel, also can adopt PVC sheet material to weld.

The utility model is when operation, and at first, the 2-3% ceramic fibre slurries that preparation finishes enter first-class slurry chamber 102 through the conveying of pump via stock inlet 101, and first baffle plate 200 of crossing the second stream slurry chamber 103 then enters the second stream slurry chamber 103.In the second stream slurry chamber 103, slurries are stopped by flashboard 105, flow velocity reduces, the slurries of big flow are running into flashboard 105 back backflows, in the second stream slurry chamber 103, form certain eddy current, add the horizontal stirring of second doctor-roll 104, thereby, improve the deployment conditions of slurries on the conveyer trough width slurries mixing dispersion.Through the slurries of flashboard 105, after entering the 3rd stream slurry chamber 108, run into second baffle 201, thereby can form little eddy current once more, and the current stabilization that slurries can be slowed down.108, the first doctor-rolls 107 laterally stir once more in the 3rd stream slurry chamber, disperse slurries, increase the uniformity of slurries on the conveyer trough width once more, finally disperse slurries process fourdrinier wire 109 completely, last net forming.

The utility model conveyer trough is the eddy current by slurries and laterally stir the degree of scatter of improving slurries mainly, and the processing by baffle plate, reduces the flow velocity of slurries, and plays the effect of current stabilization, thereby effectively improve slurries in conveyer trough distribution situation transversely.
