In some embodiments, the second step area is provided with a baffle.
From this, the fender can slow down the speed of the flow direction play thick liquid mouth of thick liquids, reduces the impulsive force of giving the thick liquids when stirring roller and homogenate roller rotate, makes the more steady outflow play thick liquid mouth of thick liquids, improves out thick liquid stability and homogeneity.
In some embodiments, the slurry outlet is provided with a brushing flat roller and a steering roller.
The leveling roll and the turn roll are thereby matched to form the slurry into a plate shape.
In some embodiments, the turning roll is capable of conveying a felt.
Therefore, the felt is convenient for slurry to be adhered, and the slurry is uniformly formed into a plate shape.
In some embodiments, the slurry level in the tank is higher than both the stirring roller and the homogenizing roller.
From this, the liquid level of thick liquids is higher than stirring roller and homogenate roller for stirring roller and homogenate roller reduce when rotating to be drawn into the thick liquids with the air, reduce the thick liquids bubble and form, do benefit to and improve thick liquids quality, have solved stirring roller and homogenate roller and have rotated the easy problem of forming the bubble in being drawn into the thick liquids with the air when rotating, influence thick liquids quality.
The utility model has the advantages that: the stirring roller and the homogenizing roller are arranged, so that the slurry can be effectively stirred and homogenized, fiber flocculation is reduced, and the quality of the slurry is improved;
the slurry flows from bottom to top and then passes through the stirring roller and the homogenizing roller, so that the slurry is stirred and homogenized more fully in the flow from the slurry inlet to the slurry outlet;
finally, in the working state, the liquid level of the slurry is higher than that of the stirring roller and the slurry homogenizing roller, so that the entrainment of air can be reduced, the formation of bubbles is reduced, and the quality of the slurry is improved.
