Description
Technical field
The invention belongs to celluloses to stir field, be related to a kind of stirring means of cellulose.
Background technique
Hollow extrusion molding cement plate, also referred to as ECP plate are that (paper pulp fiber, polypropylene are fine with portland cement, fiber
Dimension etc.), siliceous material (silica flour etc.) be primary raw material, through vacuum high-pressure extrusion molding, by low-temperature steam maintenance operating it
Afterwards, manufactured hollow profile board is conserved using high temperature and pressure.
The EPC plate of the current independent research of my company, is related to the processing to cellulose in process of production, specifically needs
The room temperature aqueous solution of cellulose is obtained, and must be uniform by cellulose dissolution, can guarantee the intensity of EPC plate.And cellulose
Be in room temperature it is insoluble, my company is in order to attempt to make cellulose be scattered in water using mixing plant by cellulose dissolution Yu Shuizhong
In.Commercially available agitator tank used in my company's production old type tube product is first attempted to, as a result cellulose point occurs in this mode
It dissipates not open, dissolves non-uniform problem, it is impossible to meet the production requirements of my company.Later my company arrange professional to I
State coastal area, main mixing plant manufacturer find suitable mixing plant, my associate tested a lot of stir
Mixing equipment, but the aqueous solution that these mixing plants obtain after continuously stirring 2 hours to cellulose, however it remains white point, naked eyes
Visible white point is not scattered cellulose, or even the case where burn during the test there have been motor.To fiber
The mixing time of element is too long and has the problem big, at high cost that consumes energy, and is not suitable for producing.So not having in existing technology
Meet the mixing plant of my companies needs.For this purpose, my company is merely able to self-organization research and development, fortunately, by a large amount of real
It tests and studies, my company finally realizes the product and method for meeting production requirement.
In conclusion existing at present can not all dissolve cellulose, there is, low efficiency poor to the dispersion effect of cellulose,
Motor is easy the problem of burning when stirring cellulose.
Goal of the invention
The object of the present invention is to provide a kind of stirring means of cellulose.The present invention can by cellulose all dissolve, have pair
The dissolved efficiency of cellulose is high, solute effect is good and motor is not easy the advantages of burning.
The present invention adopts the following technical scheme that realization goal of the invention:
A kind of stirring means of cellulose, which is characterized in that stirred this method comprises: room temperature in agitator tank is added in cellulose and water
It mixes；The amount ratio of the cellulose and water is 1:(90-110)；The revolving speed of the agitating shaft of the agitator tank is 1400-1600r/
Min, the dispersion disk diameter of shaft bottom are 0.35-0.45m；；The tank body internal diameter of the agitator tank is 1.4-1.6m, is highly
3-3.4m；The dispersion impeller is away from tank base 0.5-0.7m.
In the stirring means of cellulose above-mentioned, the amount ratio of the cellulose and water is 1:100.
In the stirring means of cellulose above-mentioned, the revolving speed of the agitating shaft of the agitator tank is 1480r/min.
In the stirring means of cellulose above-mentioned, the viscosity of the cellulose is 200,000 viscositys.
In the stirring means of cellulose above-mentioned, the additional amount of the water is 1.4-1.6t.
In the stirring means of cellulose above-mentioned, the agitator tank uses the variable-frequency motor of 37kW.
In the stirring means of cellulose above-mentioned, the time of the stirring is 4-6min.
In the stirring means of cellulose above-mentioned, it is highly 3.2m that the tank body internal diameter of the agitator tank, which is 1.5m,.
In the stirring means of cellulose above-mentioned, the dispersion impeller is away from tank base 0.6m.
In the stirring means of cellulose above-mentioned, the dispersion impeller is the tooth-like dispersion impeller in periphery, diameter 0.4m.
Compared with prior art, the invention has the following advantages:
1, dissolution can be stirred to the cellulose of 200,000 viscositys through the invention, and it is only necessary to 5min or so can be completed,
And the cellulose of 15kg disposably can be about dissolved in 1.5 tons of water, stirring efficiency is high.
2, it is observed that the cellulose solution finally obtained by the method for the invention is uniformly exquisitely carved, no white point has dissolution effect
The good advantage of fruit.And by after cellulose solution standing a few hours, solution is still transparent, and no white point occurs.
3, the present invention uses the variable-frequency motor of 37kW, and when to disperse disk rotating speed be 1400-1600r/min, it is ensured that final
Stirring efficiency, have the function of automatic frequency-conversion, protection realized to motor itself, motor is not easy to burn, long service life；Through trying
Test, if motor is non-frequency motor, since the viscosity of cellulose is very big, motor in driving mixing component in its dispersion process,
Motor can be burnt because of excess load；Energy consumption can be improved if the power of motor is higher, leads to the raising of production cost.
4, it is tested, has and be only 1.4-1.6m in the tank body internal diameter of agitator tank given to this invention, be highly 3-
3.4m；The dispersion disk diameter of shaft bottom is 0.35-0.45m；Dispersion impeller is away from tank base 0.5-0.7m parameters range
Interior, the dissolution of cellulose in water can be completed in 5min or so.Beyond or below tank body given to this invention and dispersion
The parameter area of disk is all unable to get optimal working efficiency and effect.As: dispersion impeller is arranged in away from tank base 90cm
Highly, cellulose can not all be dissolved continuous stirring in water cellulose 1 hour.
5, stirring jar structure defined by the present invention is simple, comprises only a motor and a dispersion impeller, is fabricated to
This low advantage；Existing agitator tank some is also additionally arranged in stirring pot bottom to fiber including at least two dispersion impellers, some
The crushing device of element, but in practical applications, these designs even can not all dissolve cellulose within 2 hours,
For stirring cellulose, these devices are the costs of manufacture for increasing equipment in vain.
6, the present invention can be achieved by cellulose uniform dissolution in normal-temperature water, and required energy consumption is very small.It is set in of the invention
Under the property room temperature for considering cellulose during meter, cellulose was not only not soluble in water, but also did not dissolved in general organic solvent, also not
It is dissolved in dilute alkaline soln.Therefore paid high-temperature water on probation improves the dissolubility of cellulose, when water temperature is improved to 90 DEG C or so, nothing
Need any stirring that can be directly dissolved in water with regard to cellulose, but water temperature needed for producing EPC plate cannot be excessively high, high temperature is molten
The solution of cellulose is solved in water temperature drop, cellulose will appear the phenomenon that gelling is layered, and be unable to meet production requirement.And
It improves water temperature and also results in greatly increasing for energy consumption, production is got up not cost-effective.Conversely, cellulose can be directly dissolved in by the present invention
Design in normal-temperature water has the advantages that low energy consumption.
In summary: the present invention can all dissolve cellulose in 5min, substantially increase the dissolution effect to cellulose
Rate；Obtained cellulose solution, uniform exquisitely carved, no white point, solute effect are fabulous；Pass through the restriction to motor, tank body, dispersion impeller
The finally solute effect to cellulose is directly ensured；And the dissolution equipment structure used is simple；Low manufacture cost；Can directly by
Cellulose is dissolved in the water of room temperature.
