Abstract

The utility model relates to papermaking dehydration equipment and provides a squeeze dewatering device of a paper machine, which has the advantages that the structure is reasonable, the squeeze dewatering effect is good, water is not accumulated on the surface of a squeeze roll, moisture in wet paper sheets can be effectively removed and the quality of the formed paper is good. The squeeze dewatering device comprises a bracket, a squeeze roll and a suction roll, wherein the squeeze roll is designed to be rotatably arranged on the bracket through squeeze roll shafts on the two ends of the squeeze roll; the suction roll is wrapped with a layer of water-absorbing material layer on the outside of the circumference, the circumferential outer surface of the water-absorbing material layer contacts with the circumferential outer surface of the squeeze roll, the suction roll is rotatably arranged on the bracket through suction roll shafts on the two ends of the suction roll, and the suction roll shafts are connected with the squeeze roll shafts in a transmission way.

Description

A kind of paper machine squeeze dehydration unit

Technical field

The utility model relates to the papermaking dehydrogenation drying equipment, particularly a kind of paper machine squeeze dehydration unit.

Background technology

Development along with society; The raising of people's living standard, market have proposed increasingly high height to the quality of paper and have asked, in the paper-making process; The moisture of the l Water Paper page or leaf band that comes out from wet end is too big; Before getting into cylinder dried portion and drying, need further dewater with pressing mode to the l Water Paper page or leaf after being shaped through press section, make when the l Water Paper page or leaf gets into cylinder dried portion not easy fracture and cracking; L Water Paper page or leaf behind the further press dewatering of press section gets into cylinder dried portion can save the heat of cylinder dried portion, improves the drying efficiency of page.

Existing papermaking press section generally adopts the plain press roller that the l Water Paper page or leaf is carried out press dewatering, and the plain press roller has smooth smooth roll surface, and the l Water Paper page frame table after the plain press roll-in is pressed is smooth; But because its circumferential outer surface of plain press roller is very smooth; Moisture is prone to rest on the pressure roller surface, the normal phenomenon that squeezing roller strap water occurs, and the lip-deep moisture of pressure roller can be got back in the l Water Paper page or leaf of follow-up squeezing in the expressing process; Cause page to return wet phenomenon, influence the squeezing effect of l Water Paper page or leaf.

In order to solve the phenomenon of plain press roller surface area water; Those skilled in the art have developed the surface grooved press roller of water delivery groove and the blind press that the surface is provided with blind hole have been set; Though can play certain effect; But DeGrain, and the l Water Paper page frame table out-of-flatness after grooved press roller and blind press squeezing, the Forming Quality of paper is poor.

The utility model content

To the problems referred to above, but the utility model propose a kind of rational in infrastructure, press dewatering is effective, the good paper machine squeeze dehydration unit of moisture content, paper Forming Quality in the surperficial not ponding of the pressure roller effective elimination l Water Paper page or leaf.

For solving this technical problem; The utility model is taked following scheme: a kind of paper machine squeeze dehydration unit; Comprise support, pressure roller, said pressure roller are located on the support through the squeezing roll shaft of being located at its two ends is rotating, also comprise suction roll; Said suction roll periphery coats one deck absorbent material layer; Said absorbent material layer circumferential outer surface contacts with the circumferential outer surface of said pressure roller, and said suction roll is located on the support through the suction roll shaft of being located at its two ends is rotating, and said suction roll shaft is connected with pressure roller through-drive through belt drive unit.

Further improvedly be: said suction roll is one or more.

Further improvedly be: the diameter of said suction roll is littler than the diameter of pressure roller, the diameter of said suction roll be the pressure roller diameter 10 to 1 15 between.

Through adopting the aforementioned techniques scheme; The beneficial effect of the utility model is: the utility model paper machine squeeze dehydration unit has the suction roll of absorbent material layer and suction roll is contacted with the pressure roller circumferential surface through setting up a surface, when squeezing work like this; Just can absorb the moisture of pressure roller surface detention through the absorbent material layer of suction roll periphery; Make the pressure roller surface not be with water, solved prior art, the l Water Paper page or leaf is caused back wet phenomenon because of pressure roller surface band water; But the moisture content in the effective effective elimination l Water Paper of the press dewatering page or leaf, the paper Forming Quality that produces is good.

Description of drawings

Fig. 1 is the utility model example structure sketch map.

The specific embodiment

Combine accompanying drawing and specific embodiment that the utility model is further specified at present.

With reference to figure 1; Present embodiment discloses a kind of paper machine squeeze dehydration unit, comprises support 1, pressure roller 2, two squeezing roll shafts 21, suction roll 3, suction roll shaft 31; Squeezing roll shaft 21 rotating are located at support 1 on of said pressure roller 2 through being located at its two ends; Said suction roll 3 periphery coat one deck absorbent material layer 32, and said absorbent material layer 32 circumferential outer surfaces contact with the circumferential outer surface of said pressure roller 2, and suction roll shaft 31 rotating are located at support 1 on of said suction roll 3 through being located at its two ends; Said suction roll shaft 31 is in transmission connection through belt drive unit 4 and squeezing roll shaft 21, and suction roll 3 rotates with pressure roller 2 during work.

Said suction roll is 5, and a plurality of suction rolls are set, and soaking effect is better, has prolonged the time of changing suction roll, and simultaneously, when a suction roll was changed absorbent material layer, several in addition suction rolls can also work on.

The diameter of said suction roll 3 is littler than the diameter of pressure roller 2, and the diameter of said suction roll 3 is 1 15 of pressure roller 2 diameters, the suction roll dismounting of minor diameter, change more convenient.

This novel papermaking machine squeeze dehydration unit can also connect a drive unit in addition with the suction roll shaft; Pressure roller and suction roll are worked alone; When changing suction roll water absorbent surface material layer, just need not stop the work of pressure roller like this, can enhance productivity.

The utility model paper machine squeeze dehydration unit; Have the suction roll of absorbent material layer and suction roll is contacted with the pressure roller circumferential surface through setting up a surface; During squeezing work, just can absorb the moisture of pressure roller surface detention like this, make the pressure roller surface not be with water through the absorbent material layer of suction roll periphery; Solved prior art because of pressure roller surface band water; The l Water Paper page or leaf is caused back wet phenomenon, but the moisture content in the effective effective elimination l Water Paper of the press dewatering page or leaf, and the paper Forming Quality that produces is good.

The above record is merely the embodiment that utilizes this origination techniques content, anyly is familiar with modification, the variation that this creation of this art utilization is done, and all belongs to the claim of this creation opinion, and is not limited to embodiment announcement person.
