Description

Technical field:

[0001] The utility model belongs to the field of papermaking, in particular to a water collecting device for a pressing and dewatering roller of a papermaking machine. Background technology:

[0002] With the rapid development of society, the demand for paper in daily life and all walks of life is getting higher and higher, and the quality requirements for paper are becoming more and more stringent. In the paper production process, the wet paper strip coming out of the wire section has a large amount of moisture. Before drying, the wet paper strip needs to be pressed and dehydrated in the pressing section to make it less likely to crack in the drying cylinder section. At the same time, it can also reduce the energy consumption of the drying cylinder section and improve the drying efficiency of the paper sheets.

[0003] The existing papermaking press section usually places the wet paper stock on a dewatering conveyor cloth, and then uses two upper and lower pressing rollers to press and dehydrate the wet paper stock in the interlayer of the dewatering conveyor cloth. The squeezed water falls onto the lower pressing roller and splashes along the bottom arc surface of the lower pressing roller. It cannot fall into the water collection trough on the ground, causing the working ground to be seriously contaminated by the squeezed water, and on-site workers are prone to slipping and getting injured when walking. Utility model content:

[0004] The utility model aims to provide a water collecting device for a press dewatering roller of a paper machine, and overcomes the shortcomings of the above-mentioned prior art, and effectively solves the existing problem of turbulent flow of squeezed water.

[0005] Contents of the utility model: A water collecting device for a papermaking machine pressing and dewatering roller, comprising a frame, an upper pressing roller and a lower pressing roller are mounted on the frame, a dewatering conveying cloth is transmitted between the upper pressing roller and the lower pressing roller, a concave water collecting plate inclined downward is arranged below the dewatering conveying cloth, the outer end of the concave water collecting plate is fixedly connected to a water collecting trough, the outer end of the concave water collecting plate extends into the inner cavity of the water collecting trough, the water collecting trough is mounted on the frame, a drain pipe is connected to the bottom wall of the water collecting trough, and the bottom end of the drain pipe extends into the inner cavity of the water storage tank.

[0006] Furthermore, reinforcing ribs are installed between the concave water collecting plate and the water collecting trough.

[0007] Furthermore, guide oblique blocks are installed at both ends of the inner cavity of the water collecting tank.

[0008] Furthermore, the inner end of the concave water collecting plate is slidably fitted with the outer circumferential surface of the lower pressure roller.

[0009] Furthermore, the width of the concave water collecting plate is greater than the width of the dewatering transfer cloth.

[0010] Furthermore, the water storage tank is located below the lower pressing roller.

[0011] Furthermore, I-beam legs are installed at both ends of the water collecting trough, and the bottom ends of the I-beam legs are fixedly connected to the crossbeam of the frame.

[0012] The beneficial effects of the utility model are as follows: the water squeezed out by the dewatering conveying cloth can be collected into the water collecting trough through the concave water collecting plate, and finally concentrated into the water storage tank for temporary storage, thereby avoiding the contamination of the working ground caused by splashing of the squeezed dewatering water and preventing the workers from slipping and getting injured.
