Surface rank and the adjustment manner of concentration in the measuring tank of the component stock

摘要

(57) Abstract Surface rank (L20) and the adjustment manner of concentration (Cs₂₀) in the stock chest (20) for measurable variable of component stock (M₁). The stock as outside directions current (F₁₁) to the stock chest (20) the giving sending it does with the 1st pump (11) from cartridge head (10a) of the storage tower (10). The 1st dilution water flow (F₁₅) is made to pass to directions current (F₁₁) outside this, to the stock chest (20) concentration of the stock which the giving sending is done is adjusted the level of desire with this dilution water flow. This stock as measurable variables current (F₁) the paper machine or board paper machine the giving sending it does briefly to rotary flow from the stock chest (20) with the 3rd pump (21). It maintains uniformly the surface rank (L20) in the stock chest (20) due to the overflow (F₁₃) which is sent to the pumping tank (20a) from the stock chest (20). You reset to the cartridge head (10a) of the storage tower (10) the stock as returns current (F₁₂) due to the 2nd pump (12) from the pumping tank (20a), you adjust the concentration in the cartridge head (10_a) of the storage tower (10) with this the level of desire. In order to offer uniform concentration, it agitates strongly the stock (M₁) cartridge head (S₁₀) of the storage tower (10) and in the stock chest (20, S₂₀).
