Abstract
The device for improving the concentration of the papermaking pulp comprises a pulp storage tower, a paper machine pulp pump and a pulp inlet pipe, wherein a backflow pulp pump is arranged on the other side of the pulp storage tower, backflow pulp pipes are arranged at two ends of the backflow pulp pump, one end of each backflow pulp pipe is connected with the bottom of the pulp storage tower, the other end of each backflow pulp pipe is located at the top of the pulp storage tower, an inclined screen is arranged between the lower surface of each backflow pulp pipe and the top of the pulp storage tower, and a white water pipe outside the pulp storage tower is connected with the inclined screen. When the concentration of the paper pulp is low, a reflux pump is started, and the inclined screen is used for dewatering, so that the concentration of the paper pulp is quickly improved. When the pulp concentration meets the papermaking requirement, the reflux pump is closed, the automatic control can be realized, the start and stop of the reflux pump are controlled by utilizing the signal of the concentration regulator, the stability of an oven dry quantity control system is facilitated after the pulp concentration is stabilized, and the quantitative deviation cannot be larger due to too low pulp concentration.
Description
Technical Field
The utility model relates to an effectively improve device of papermaking thick liquid concentration.
Background
The paper mill has strict requirements on the concentration of pulp in the papermaking process, the concentration regulator can be regulated by adding water when the concentration is high, the ration and the gram weight of finished paper can be seriously influenced when the concentration is low, the quality of the paper is seriously influenced, the flow can be increased by absolute dry quantity calculation when the concentration is low, more waste water is generated, water treatment is not facilitated, and the condition that the pulp concentration is smaller inevitably occurs in the beating process. It is necessary to invent a device for effectively increasing the concentration of paper pulp.
Disclosure of Invention
An object of the utility model is to provide an improve device of papermaking paper pulp concentration, solve the unstable problem of concentration.
The technical scheme of the utility model, improve the device of papermaking paper pulp concentration, including depositing thick liquid tower, paper machine stuff pump, advancing the thick liquid pipe, the opposite side of depositing the thick liquid tower is equipped with the backward flow stuff pump, and backward flow stuff pump both ends have backward flow thick liquid pipe, and the backward flow thick liquid pipe has valve one end to connect deposits thick liquid tower bottom, and the other end is located deposits thick liquid tower top, flows under the thick liquid pipe and deposits and be equipped with the inclined screen between the thick liquid tower top, deposits the plain boiled water union coupling inclined screen in the thick liquid tower outside. When the concentration of the paper pulp is low, a reflux pump is started, and the inclined screen is used for dewatering, so that the concentration of the paper pulp is quickly improved. A reflux pump is added at the bottom of the pulp tower, and the reflux pump is pumped to an inclined sieve above the pulp tower through a pulp pipe, so that the pulp is dewatered through filtration, and the pulp concentration is improved.
The utility model has the positive effects that; the investment is small, the structure is simple, the installation is rapid, and the pulp concentration is stable.
Drawings
Fig. 1 is a schematic structural diagram of the device of the present invention.
In the figure: 1 pulp storage tower, 2 pulp inlet pipes, 3 paper pulp, 4 pulp pump valves, 5 paper pulp pumps, 6 paper pulp pipes, 7 valves, 8 backflow pulp pumps, 9 backflow pulp pipes, 10 inclined sieves and 11 white water pipes.
Detailed Description
As can be seen from figure 1, the device for improving the concentration of the papermaking pulp comprises a pulp storage tower 1 and a pulp inlet pipe 2, wherein the pulp storage tower 1 is internally provided with the pulp 3, and the outer side of the pulp storage tower 1 is provided with a pulp machine pump 5 and a pulp machine pipe 6. The other side of depositing thick liquid tower 1 is equipped with backward flow stuff pump 8, and backward flow stuff pump 8 both ends have backward flow thick liquid pipe 9, and backward flow thick liquid pipe 9 has valve 7 one end to connect and deposits thick liquid tower 1 bottom, and the other end is located and deposits thick liquid tower 1 top, is equipped with inclined screen 10 below backward flow thick liquid pipe 9 and between depositing the thick liquid tower 1 top, deposits the white water pipe 11 in the thick liquid tower 1 outside and connects inclined screen 10.
When the concentration of the paper pulp is low, the reflux pump is started, the inclined screen is used for dewatering, the concentration of pulp is rapidly improved, white water which is separated from the paper pulp flows to the white water tank through the white water pipe, the reflux pump is closed after the concentration of the pulp meets the papermaking requirement, automatic control can be made, and the start and stop of the reflux pump are controlled by signals of the concentration regulator.
