The invention discloses a boiling device for papermaking. The boiling device comprises a boiling tank, wherein one side of the top end of the boiling tank is connected with a wood sheet feeding box through a wood sheet conveying pipeline; one side of the bottom part of a boiling liquid feeding box is connected with the top end of the boiling tank through a boiling liquid conveying pipe; one end of a hot medicine liquid conveying pipe is connected with a hot medicine liquid feeding box; a display screen is arranged at one side of the hot medicine liquid feeding box; a hot medicine liquid spraying pipe is arranged at the bottom end of a horizontal pipeline; a liquid level sensor is arranged at the inner wall of one side of the boiling tank, a controller is arranged at the bottom end of the boiling tank, and a flowmeter is arranged at the top end of a liquid drain pipe. The boiling device has the beneficial effects that the wood sheets, boiling liquid and hot medicine liquid can be conveniently conveyed, the hot medicine liquid can be quickly and uniformly dispersed into the boiling liquid, the working efficiency is improved, the output amount of boiling liquid can be conveniently recorded, the height of the boiling height can be acknowledged, the boiling liquid can be conveniently regulated and controlled in the later stage, and the calculation workload in the later stage can be reduced.
Description
technical field [0001] The invention relates to the field of papermaking machinery, in particular to a digester for papermaking. Background technique [0002] Many mechanical equipment are used in the papermaking process, including wood grinders, digesters, and pulp bleachers, and the digester dissolves the lignin in the papermaking raw materials into the cooking liquid to separate the papermaking raw materials into fibers. equipment. Although the digester plays a great role in the papermaking process, it also has certain disadvantages. For example, because of its large size, it is inconvenient to transport wood chips, cooking liquid and winding liquid, and it is inconvenient to quickly and evenly heat the liquid. Dispersed into the cooking liquid, often this process takes a long time, and it is inconvenient to record the output of the cooking liquid and understand the height of the cooking liquid, and then it will be more troublesome to control and count the cooking liquid...
