The purpose of this utility model is achieved through the following technical solutions:
The vacuum dewatering system of a kind of papermaking press portion is provided, comprise the upper press and lower press and the top felt through described upper press and described lower press and the lower felt that are arranged at paper feed end, described top felt and described lower felt all form the pressed zone of circulation by multiple idler roller tensionings;
Described top felt is provided with upper suction box near a side of described paper feed end, the top of described upper suction box and described top felt close contact, described lower felt is provided with lower suction box near a side of described paper feed end, the top of described lower suction box and described lower felt close contact;
The top of described upper suction box and the top of described lower suction box are provided with cellular type vacuum panels, and described upper suction box is connected with vavuum pump respectively with described lower suction box.
Wherein, the surface of described cellular type vacuum panels offers multiple suction holes, and described suction hole sets in a row.
Wherein, the surperficial percent opening of described cellular type vacuum panels is greater than 90%.
Wherein, on the pipeline that described upper suction box is connected with described vavuum pump with described lower suction box, be respectively arranged with vacuum valve.
the beneficial effects of the utility model:
The vacuum dewatering system of papermaking press of the present utility model portion, comprise the upper press and lower press and the top felt through upper press and lower press and the lower felt that are arranged at paper feed end, top felt and lower felt all form the pressed zone of circulation by multiple idler roller tensionings; Top felt is provided with upper suction box near a side of paper feed end, the top of upper suction box and top felt close contact, and lower felt is provided with lower suction box near a side of paper feed end, the top of lower suction box and lower felt close contact; The top of the top of upper suction box and lower suction box is provided with cellular type vacuum panels, and upper suction box is connected with vavuum pump respectively with lower suction box.Compared with prior art, the upper suction box of vacuum dewatering system of the present utility model and the top of lower suction box have all adopted cellular type vacuum panels, this panel cut out rate is large, and contact smoothly with lower felt with top felt, can in time the water on felt be siphoned away, improve dewatering efficiency, reduce the moisture that splenium paper, saved steam, the power that under square one, vavuum pump needs can reduce half, thereby significantly reduces energy consumption.
