Abstract
The utility model relates to the technical field of rollers, in particular to hot-press roller for a paper machine. The hot-press roller for the paper machine comprises a roller body. A conical main flow channel is formed in the roller in the axial direction of the center axis. The size of a water inlet of the conical main flow channel is larger than the size of a water outlet of the conical main flow channel. A plurality of conical branch flow channels are evenly formed in the perpendicular direction of the conical main flow channel. The diameter of an opening formed in the bottom of each conical branch flow channel is smaller than that of an opening in the top of the conical branch flow channel. According to the hot-press roller for the paper machine, due to the fact that the structure of the flow channels formed in the roller body is quite reasonable, the surface of the roller body is fully heated, and it is guaranteed that the surface temperature of the roller body is even.
Description
Technical field
The utility model relates to the technical field of roll, especially a kind of thermal press rolls for 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, the utility model provides a kind of thermal press rolls for paper machine, structure by the chute that portion offers is within it very reasonable, allow roll body surface be heated fully simultaneously, guarantee that the temperature on roll body surface keeps being uniformly distributed.
The utility model solves the technical scheme that its technical problem adopts: a kind of thermal press rolls for paper machine, comprise roll body, on the axial direction of the central shaft of roll body, offer a taper sow (channel), the size of the water inlet of taper sow (channel) is greater than the size of delivery port, in the vertical direction of taper sow (channel), evenly offer many tapered shunting grooves, the bottom opening diameter dimension of tapered shunting groove is less than open top diameter dimension.
Further limit: the open top that is evenly opened in many tapered shunting grooves in the vertical direction of taper sow (channel) equates to the distance of the axis of central shaft.
Further limit: the water outlet end periphery on central shaft offers two supplementary chutes.
The beneficial effects of the utility model: this thermal press rolls for paper machine, by portion within it, offer structure and more reasonably add heated launder, heated in roll body surface simultaneously fully, cause the temperature on roll body surface to keep equal state, temperature keeps being uniformly distributed, do not cause temperature difference phenomenon, extended the service life of roll.
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, roll body, 2, central shaft, 3, taper sow (channel), 3-1, water inlet, 3-2, delivery port, 4, tapered shunting groove, 5, supplement chute.
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.
Thermal press rolls for paper machine as shown in Figure 1, comprise roll body 1, on the axial direction of the central shaft 2 of roll body 1, offer a taper sow (channel) 3, the size of the water inlet 3-1 of taper sow (channel) 3 is greater than the size of delivery port 3-2, in the vertical direction of taper sow (channel) 3, evenly offer many tapered shunting grooves 4, the bottom opening diameter dimension of tapered shunting groove 4 is less than open top diameter dimension.
The open top that is wherein evenly opened in many tapered shunting grooves 4 in the vertical direction of taper sow (channel) 3 equates to the distance of the axis of central shaft 2.Water outlet end periphery on central shaft 2 offers two supplementary chutes 5.
When heating oil enters after the water inlet 3-1 of taper sow (channel) 3, because the size of the water inlet 3-1 of taper sow (channel) 3 is greater than the size of delivery port 3-2, so except a part of heating oil flows to the direction of delivery port 3-2, remaining heating oil will be got into be uniformly distributed in taper sow (channel) 3 many tapered shunting grooves 4 around, in addition the water outlet end periphery on central shaft is offered supplementary chute, can avoid, because of the lower phenomenon of the narrow temperature of taper sow (channel) 3 chute herein, temperature supplementary heating having been carried out in this position, place.
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.
