Abstract
The utility model relates to the technical field of drying devices, in particular to a drying device for a paper machine. The drying device for the paper machine comprises a box which is inclosed all around, a plurality of hot wind rollers are mounted in the box, an air blower is connected to the lower portion of the left side of the box, the air blower is connected with hot air pipes, an air extractor is connected to the upper portion of the right side of the box, the other end of the air extractor is connected with a variable frequency motor, and each hot wind roller comprises a metal roller body, a stainless steel layer arranged on the outer surface of the circumference of the mental roller body and a ceramic layer arranged on the outer surface of the circumference of the stainless steel layer. According to the drying device for the paper machine, the rotating speed of the air extractor and the rotating speed of the air blower can be adjusted according to specific conditions, a great amount of electric energy is saved, and due to the fact that the structure of the hot wind rollers is novel, the hot wind rollers are low in cost, high in dehydration efficiency and long in service life.
Description
Technical field
The utility model relates to the technical field of drying unit, especially a kind of drying unit for paper machine.
Background technology
Paper machine is the equipment of combining of paper making, is mainly made up of the part such as net, pressing and drying.Two kinds of mesh portions cylinder and fourdrinier wires, press section is made up of pressure roller and papermaker's felt etc., and drying section is made up of one or several drying cylinder.Some fourdrinier is also equipped calender, to improve smoothness and the tightness etc. of paper.The type of paper machine is a lot, as manufacture machine glazing paper MG. machine, manufacture paper many drying cylinders of fourdrinier wire paper machine, manufacture typing paper and cigarette paper etc. thin-paper machine, manufacture the board machine etc. of cardboard.
Drying unit is one of parts very important in paper machine, drying unit is that the moisture that utilizes dry hot blast to make to be attached to the paper on hot air roll becomes steam and extracts out by air exhauster, but structurally there is certain defect in existing drying unit, the invariablenes turning speed speed change as requested of its air exhauster of existing drying unit and air blast, causes the unnecessary consumption of electric weight.
Simultaneously, use the material that is easy to peel off with paper to make because the hot air roll on existing paper machine is normal, mostly use granite, granitic main feature is in its tissue, to have many small holes, storing certain air, be conducive to peeling off of l Water Paper page, but that its shortcoming is cost is high, is easy to embrittlement.On-stream, as too fast in rotating speed or load that excessive may to produce spindle nose overheated, stone roll surface is produced axially or circumferential crack, when high-temperature expansion is serious, can cause axle center to come off, dewatering efficiency is low, service life is short.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the problem proposing in above-mentioned background technology, the utility model provides a kind of drying unit for paper machine, the rotating speed of its air exhauster and air blast can regulate according to specific circumstances, has saved a large amount of electric energy; Due to the novel structure of hot air roll, make the cost of hot air roll low, dewatering efficiency is high, long service life simultaneously.
The utility model solves the technical scheme that its technical problem adopts: a kind of drying unit for paper machine, comprise in casing that surrounding is airtight, casing some hot air rolls are installed, the below, left side of casing is connected with air blast, on air blast, be connected with hot air duct, the top, right side of casing is connected with air exhauster, the other end of air exhauster is connected with variable-frequency motor, and hot air roll comprises metallic roll body, be located at the stainless steel layer of metallic roll body circumferential outer surface and be located at the ceramic layer of stainless steel layer circumferential outer surface.
Further limit: electrically-controlled valve is installed on hot air duct.
Further limit: electrically-controlled valve is electric air control valve.
The beneficial effects of the utility model: this is used for the drying unit of paper machine, the rotating speed of its air exhauster and air blast can regulate according to specific circumstances, has saved a large amount of electric energy; Due to the novel structure of hot air roll, make the cost of hot air roll low, dewatering efficiency is high, long service life simultaneously.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
In figure: 1, casing; 2, hot air roll; 2-1, metallic roll body; 2-2, stainless steel layer; 2-3, ceramic layer; 3, air blast; 4, hot air duct; 5, air exhauster; 6, variable-frequency motor; 7, electrically-controlled valve.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The drying unit for paper machine as shown in Figure 1, comprise in casing 1 that surrounding is airtight, casing 1 some hot air rolls 2 are installed, the below, left side of casing 1 is connected with air blast 3, on air blast 3, be connected with hot air duct 4, the top, right side of casing 1 is connected with air exhauster 5, the other end of air exhauster 5 is connected with variable-frequency motor 6, and hot air roll 2 comprises metallic roll body 2-1, be located at the stainless steel layer 2-2 of metallic roll body 2-1 circumferential outer surface and be located at the ceramic layer 2-3 of stainless steel layer 2-2 circumferential outer surface.Wherein on hot air duct 4, electrically-controlled valve 7 is installed.Electrically-controlled valve 7 is electric air control valve.
This is used for the drying unit of paper machine, and the rotating speed of its air exhauster 5 and air blast 3 can regulate according to specific circumstances, has saved a large amount of electric energy; Due to the novel structure of hot air roll 2, make the cost of hot air roll low, dewatering efficiency is high, long service life simultaneously.
Taking above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this utility model technological thought, carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to claim scope.
