Abstract

A kind of suction groovedpress roller, it comprises that a surface offers the squeezing roll body of vacuum hole, the surface of described squeezing roll body has also been equipped with the rill of water drainage; Described rill is radial arrangement on the surface of squeezing roll body, and every radially rill be all communicated in through vacuum hole, be formed with the vacuum hole of certain percent opening and the pressure roller surface that associated radially rill forms; The utility model is the one improvement to prior art, and it has and can, improving under the condition of the paper machine speed of a motor vehicle, ensure the raising of dewatering efficiency, reduces energy resource consumption, improves the features such as production capacity and product quality.

Description

A kind of suction groovedpress roller

Technical field

The utility model relates to a kind of suction groovedpress roller, belong to the pressing part technical field of paper machine press section.

Background technology

Conventionally the press section of paper machine to be to have the vacuum furnace press dewatering of vacuum hole as main, but along with the development of paper technology, the speed of a motor vehicle of papermaking equipment improves, but improve limited with the efficiency of vacuum hole dehydration merely, improve the speed of a motor vehicle, dewatering efficiency declines on the contrary, and can greatly improve energy resource consumption; Improve squeeze pressure, can bring various harmful effects.

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of technical improvement of carrying out at existing vacuum furnace, can improve under the condition of the paper machine speed of a motor vehicle, ensure the raising of dewatering efficiency, reduce energy resource consumption, improve the suction groovedpress roller of production capacity and product quality.

The purpose of this utility model completes by following technical solution, described suction groovedpress roller, and it comprises that a surface offers the squeezing roll body of vacuum hole, the surface of described squeezing roll body has also been equipped with the rill of water drainage.

Described rill is radial arrangement on the surface of squeezing roll body, and every radially rill be all communicated in through vacuum hole, be formed with the vacuum hole of certain percent opening and the pressure roller surface that associated radially rill forms.

The utility model is the one improvement to prior art, and it has and can, improving under the condition of the paper machine speed of a motor vehicle, ensure the raising of dewatering efficiency, reduces energy resource consumption, improves the features such as production capacity and product quality.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in detail: shown in Fig. 1, suction groovedpress roller described in the utility model, it comprises that a surface offers the squeezing roll body 2 of vacuum hole 1, and the surface of described squeezing roll body 2 has also been equipped with the rill 3 of water drainage.

Described rill 3 is radial arrangement on the surface of squeezing roll body 2, and every radially rill 3 be all communicated in through vacuum hole 1, be formed with the vacuum hole of certain percent opening and the pressure roller surface that associated radially rill forms.

Operation principle of the present utility model is: in the time that squeezing roll body 2 was pressed moisture paper, some water can squeezedly be compressed into rill, and rill can play the effect of drainage water on the one hand, will in the vacuum hole that wherein a part of water drainage enters to be communicated with, be siphoned away by negative pressure; And small part water can throw away under centrifugal action, thereby reach better dehydrating effect.

Claims (1)
