Abstract
The utility model relates to the technical field of heating rollers, in particular to a heating roller used on a paper making machine. The heating roller is provided with a fixing shaft of a hollow structure. The fixing shaft is sleeved with a roller body of a hollow structure in a rotatable mode. A plurality of hydrothermal solution feeding inlets are evenly distributed in the axial direction of the fixing shaft in the circumferential direction of the roller body. A plurality of bunchy hydrothermal solution flow passes are evenly distributed inside the fixing shaft in a surrounding mode. Hydrothermal solutions in the hydrothermal solution flow passes are consistent with the curve of the inner wall of the fixing shaft in moving direction. The heating roller used on the paper making machine is simple in structure, low in manufacturing cost, good in heating effect and capable of being widely used on the paper making machine.
Description
Technical field
The utility model relates to the technical field of warm-up mill, especially a kind of for the warm-up mill on paper machine.
Background technology
Papermaking apparatus is the equipment of combining of paper making, mainly net, pressing and drying etc., partly consists of.Two kinds of mesh portions cylinder and fourdrinier wires, press section is comprised of pressure roller and papermaker's felt etc., and drying section is comprised of one or several drying cylinder.Some fourdrinier is also equipped calender, to improve the smoothness of paper and tightness etc.The type of papermaking apparatus is a lot, as manufacture machine glazing paper MG. machine, manufacture paper many drying cylinders of fourdrinier wire paper machine, manufacture the thin-paper machine of typing paper and cigarette paper etc., manufacture the board machine etc. of cardboard.
Warm-up mill is one of parts important in paper machine, warm-up mill is divided into Electromechanic heating roller and conduction oil heating roller, Electromechanic heating roller adopts solenoid mode of heating, its complex structure, involve great expense, be mainly used in the occasion that temperature accuracy is had relatively high expectations, conduction oil heating roller is to utilize conduction oil as adding thermal medium, conduction oil after heating is injected into roll body inside, by heat, conduct and make roll body heat temperature raising, conduction oil heating roller is current conventional warm-up mill, interlayer warm-up mill is a typical case in conduction oil heating roller, the way of interlayer warm-up mill is first to carry out interior roller and outer roller at present, again interior roller is inserted in outer roller, then weld main shaft and two side seal boards, the mezzanine space of this interlayer warm-up mill is larger, conduction oil consumption is still relatively many, the both sides seal plate welding of the two ends of interior roller and outer roller and roll body, in order to reach good bonding strength, outer roller is relatively thick, especially for the longer warm-up mill of roll body, the thickness of outer roller barrel is too thin is easy to cause roll surface to be out of shape, and conduction oil enters another from one end of roll body and brings out, therefore the temperature difference at roll body two ends is larger, heating effect is also bad.
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, it is a kind of for the warm-up mill on paper machine, simple in structure that the utility model provides, low cost of manufacture, and heating effect is good, can on paper machine, be widely used.
The utility model solves the technical scheme that its technical problem adopts: a kind of for the warm-up mill on paper machine, the fixed axis with hollow structure, the rotatable roll body that is set with hollow structure in periphery of fixed axis, on the axial direction of fixed axis, along roll body circumferencial direction, be evenly distributed with a plurality of hydrothermal solution feeding mouths, the inner loop of fixed axis is around being evenly equipped with many hydrothermal solution runners that are pencil, and the heated fluid stream of hydrothermal solution runner moves towards consistent to the inwall curve with fixed axis.
Further limit: fixed axis comprises interior straight section, is arranged in the cone section at straight section two ends and lays respectively at two bores the section outer straight section at two ends in addition, and the diameter dimension of interior straight section is greater than the diameter dimension of outer straight section.
Further limit: the region division that the inner chamber of fixed axis and many are between the hydrothermal solution runner of pencil has heat-insulation layer.
The beneficial effects of the utility model: be somebody's turn to do for the warm-up mill on paper machine, simple in structure, low cost of manufacture, uniformity of temperature profile, heating effect is good, can on paper machine, be widely used.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1, fixed axis; 1-1, interior straight section; 1-2, middle cone section; 1-3, outer straight section; 2, roll body; 3, hydrothermal solution feeding mouth; 4, hydrothermal solution runner.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1 for the warm-up mill on paper machine, the fixed axis 1 with hollow structure, the rotatable roll body 2 that is set with hollow structure in periphery of fixed axis 1, on the axial direction of fixed axis 1, along roll body 2 circumferencial directions, be evenly distributed with a plurality of hydrothermal solution feeding mouths 3, the inner loop of fixed axis 1 is around being evenly equipped with many hydrothermal solution runners 4 that are pencil, and the heated fluid stream of hydrothermal solution runner 4 moves towards consistent to the inwall curve with fixed axis 1.
The outer straight section 1-3 that wherein fixed axis 1 comprises interior straight section 1-1, is arranged in the cone section 1-2 at straight section 1-1 two ends and lays respectively at two cone section other two ends of 1-2, the diameter dimension of interior straight section 1-1 is greater than the diameter dimension of outer straight section 1-3.The region division that the inner chamber of fixed axis 1 and many are between the hydrothermal solution runner 4 of pencil has heat-insulation layer.
Be somebody's turn to do for the warm-up mill on paper machine, simple in structure, low cost of manufacture, uniformity of temperature profile, heating effect is good, can on paper machine, be widely used.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification 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.
