Background technology

Paper is the most frequently used article in our daily life, no matter reads, reads newspaper, or writes, draws a picture, and all obtains and paper connects Touch.In industry, agricultural and national defense industry produce, also it be unable to do without paper.Today, without paper, that is just not imaginable. Paper is rapping off, transmission of culture, develop science and technology and production in terms of, be a kind of strong instrument and material, in papermaking During need to use couch roll, suction couch roll is the important component part of papermaking equipment, and on forming net, paper web is taken off From place, as the roller of forming net impulse stroke segment endpoint.Suction couch roll dewatering Principle is：Set in the inside of suction couch roll Put vacuum tank, vacuum tank is connected with vacuum pump, vacuum tank arranges water sucking mouth, after vacuum pump startup, draw in suction couch roll Moisture and air, reach the purpose of forced dehydration.

But there are some defects using suction couch roll at present, leave moisture and even form water because suction couch roll surface has Drip, especially when paper machine speed is higher, l Water Paper page will produce certain Wetback at suction couch roll, causes wet Paper strength declines, and the paper defects such as embossing easily, greatly increased the disconnected paper rate of paper machine production, has had a strong impact on production effect Rate, and the normal operation of impact paper machine, thus reducing the quality of finished paper, and suction couch roll cost input is higher.

Utility model content

The purpose of this utility model is to provide a kind of couch roll dehydration device for paper machine, possesses the excellent of automatic dehydration Point, solve suction couch roll put into higher, l Water Paper page will produce certain Wetback at suction couch roll, causes l Water Paper Page intensity declines, and the problem of the paper defects such as embossing easily.

For achieving the above object, this utility model provides following technical scheme：A kind of couch roll dehydration dress for paper machine Put, including hollow roll body and l Water Paper main body, described hollow roll body two ends are separately installed with notch cuttype major axis and notch cuttype short axle, institute State notch cuttype major axis and notch cuttype short axle is located on the central axis of described hollow roll body, the roller wall of described hollow roll body is provided with Inlet opening, the inside of described hollow roll body is provided with V-type funnel, and the end face level of described V-type funnel is along the central shaft of hollow roll body Line is arranged, and the bottom of described V-type funnel is provided with treatment hole, described treatment hole be arranged right below water leg, described water leg position In the cambered surface of the bottom of hollow roll body, described water leg is provided with drainage pipeline in the one end near notch cuttype major axis, described row Waterpipe is communicated with water leg cell body, and is located at the bottom of water leg, and described water leg is structure as a whole with V-type funnel, and collects Tank and V-type funnel are movably arranged on notch cuttype major axis and notch cuttype short axle by left and right support.

Preferably, the contact internal walls of the two-arm of described V-type funnel and hollow roll body, and the two-arm of V-type funnel and hollow roller The contact portion of body is provided with water scraper plate.

Preferably, described water leg and the left and right support of V-type funnel are fixedly installed on the body of paper machine.

Preferably, described water leg is semicircular arc structure, and half curved end of water leg is less than the upper of l Water Paper main body Surface.

Preferably, the contact internal walls of half curved end of water leg and hollow roll body, and hollow roller body inner wall smooth.

Compared with prior art, the beneficial effects of the utility model are as follows：This utility model passes through to arrange water leg and V-type Funnel, by the globule of the inwall of type collection funnel hollow roll body, prevents the globule to be again introduced in paper, will be wet by water leg The water of paper extruding is collected, and the water of collection is discharged it is therefore prevented that Wetback in dehydration through drainage pipeline, thus keeping away Exempt from that the paper defects such as embossing occur, the disconnected paper rate of paper machine production having greatly reduced, improve production efficiency, thus improve finished product The quality of paper, low cost simple by this apparatus structure, practicality is high.
