Because fibrous suspension flows towards the direction of outlet in the mixing container, for the fibrous suspension cleaned
Multi step format input advantageously, suspension nozzle for liquid is arranged side by side along the longitudinal size of stainless steel.
For the fluid impact that is sparged into, on the gauge wall of hybrid chamber and further injection is mixed so as to further promote
Close and deaerate, suspension nozzle for liquid and/or diluent nozzle should be arranged on the bottom of stainless steel or be arranged in stainless steel
On side, and towards center or downwards alignment.
In addition, additionally aiding the mixing of fluid, each suspension nozzle for liquid is equipped with diluent nozzle as far as possible.Also make herein
The fibrous suspension that outlet must be flowed to dilutes step by step.
Here, being associated with the diluent nozzle of suspension nozzle for liquid can point to towards the direction of outlet, or it is associated with suspension
The diluent nozzle of nozzle is arranged to so that the jet of the two nozzles bumps against, and this provides extra vortex.
In order that expense and space requirement minimize, the fibrous suspension diluted should use up from the outlet of stainless steel
Degassing equipment may be directly inputted.
Because fibrous suspension can flow through mixing apparatus, fibrous suspension continues conveying hardly to degassing equipment
It can be adversely affected.Therefore also without the pump between mixing apparatus and degassing equipment.
Dilution at least substantially should be made up of plain boiled water.
Then, fibrous suspension is delivered in the head box of machine after degassing equipment advantageous by head box pump.
Multiple embodiments of the present invention are illustrated in detail below.

Fig. 5 is through the cross section of another stainless steel 14.
In the constant part of the paper machine shown in Fig. 1, fibrous suspension 1 sprays into plain boiled water collection vessel 10 with high pressure
In, and by the mixing with plain boiled water 3 by pre-dilution.By prediluted fibrous suspension 1 by suspension pump 7 from mixing apparatus
The outlet of the 2 direction sensing that becomes a mandarin towards fibrous suspension is delivered to cleaning equipment, and the cleaning equipment is by multiple hydrocyclones 4
Form.As shown in Figure 2 and Figure 4, multiple hydrocyclones 4 in parallel are combined into compact washer level herein.
Hydrocyclone 4 described herein be used for clean heavy constituent concentration be 2% to 3% between fibrous suspension 1.
Due to higher concentration, cleaning equipment can be designed to smaller.
The fixed shell of hydrocyclone 4 surrounds the chamber of the strip with circular cross section.
There is entrance in the end of the chamber, by the entrance, fibrous suspension 1 to be cleaned is to be up to 4bar even
6bar pressure tangentially sprays into the Cylindrical inlet section of chamber.Thus fibrous suspension 1 forms the track of circle, wherein, it is fine
Tie up the wall portion that suspension 1 pushes chamber.
By the centrifugal force and centrifugal force acted on herein, heavy constituent is gathered in the wall portion of chamber, and light component is assembled
At the center of chamber.
In this way, the heavy constituent in the wall portion of chamber helically reaches mutually opposing, chamber herein band
