Abstract

The utility model relates to a heating roll, including the body of roll and roller, the roller setting is equipped with oil inlet and oil -out respectively at the both ends of the body of roll on the roller at body of roll both ends, and the body of roll is inside to be the cavity, and the cavity all communicates with oil inlet and oil -out, and the cavity tip is for leaking hopper -shaped, and the flare opening at cavity both ends is relative, and flare opening department is equipped with network structure's speed reduction layer, still is equipped with a plurality of reinforcing plates in the cavity, has seted up on the reinforcing plate and has led the oilhole. The utility model discloses set up the oil feed end of the body of roll into relative hourglass hopper -shaped with the end that produces oil to addding reticular speed reduction layer at the flare opening, having slowed down the velocity of flow of heating oil, prolonged the oily time that stops at body of roll cavity of heating, the heat obtains make full use of, has improved the utilization ratio of the energy.

Description

Heated roll

Technical field

The utility model relates to roll technology field, especially a kind of heated roll.

Background technology

Heated roll a kind of to be heated it by certain heater means, so its by the mode of roll extrusion, converted products is heated, compressing device.Current, there are three kinds to the mode that hot roll heats: Steam Heating, electrical heating and oil heating.Steam Heating must arrange condensed water constantly outward, electrical heating utilizes heating wire to heat hot roll, and these mode of heatings are difficult to the temperature controlling hot roll, make being heated of whole piece hot roll very uneven, temperature difference loss is comparatively large, and the larger temperature difference can affect the quality of hot roll sizing.And common oily heated roll, the flowing velocity of deep fat in roll is very fast, and the heat of oil is not fully used, and causes the waste of the energy.

Utility model content

The technical problems to be solved in the utility model is: existingly to have in heated roll the flowing velocity of oil very fast to solve, heat is not fully utilized, and causes the problem of energy waste, provides a kind of and slows down flow of hot, heated roll that oily heat utilization efficiency is high.

The utility model solves the technical scheme that its technical problem adopts: a kind of heated roll, comprise the body of roll and roll shaft, described roll shaft is arranged on the two ends of the body of roll, the roll shaft at described body of roll two ends is respectively equipped with oil-in and oil-out, described body of roll inside is cavity, described cavity is all communicated with oil-out with oil-in, described cavity end is funnel-form, the bell mouth at cavity two ends is relative, bell mouth place is provided with cancellated deceleration layer, also be provided with some stiffeners in cavity, described stiffener offers oil guiding hole.Heating oil enters body of roll cavity from the oil-in roll shaft, the end of cavity is funnel-form, the runner that heating oil enters cavity broadens gradually, its flow is constant, therefore flow velocity reduces, lural deceleration layer reduce further the flow velocity of heating oil, and heating oil is slowly flowed at body of roll cavity, and heat is fully used; When heating oil flows to oil-out end, deceleration layer and bell mouth slow down the flow velocity of heating oil again, add the time of staying of heating oil at body of roll cavity, improve the utilization rate of heating oil heat.

Oil guiding hole on adjacent stiffening plates, in being crisscross arranged, forms cross-flow, slows down the flow velocity of heating oil.

The edge of described stiffener both ends of the surface is equipped with projection, and the lateral surface of described projection and the inwall of cavity are fitted, and add the width of stiffener periphery, increase the contact area of stiffener and the body of roll, improve the Rigidity and strength of roll.

The beneficial effects of the utility model are, the oil inlet end of the body of roll and oil outlet end are set to relative funnel-form by the utility model, and set up netted deceleration layer in bell mouth, slow down the flow velocity of heating oil, extend the time that heating oil stops at body of roll cavity, heat is fully used, and improves the utilization rate of the energy.

In figure: 1. roll shaft, 2. oil-in, 3. deceleration layer, the 4. body of roll, 5. stiffener, 6. oil guiding hole, 7. protruding, 8. oil-out.

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, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.

As shown in Figure 1, a kind of heated roll, comprise the body of roll 4 and roll shaft 1, roll shaft 1 is arranged on the two ends of the body of roll 4, the roll shaft 1 at the body of roll 4 two ends is respectively equipped with oil-in 2 and oil-out 8, the body of roll 4 inside is cavity, cavity is all communicated with oil-out 8 with oil-in 2, cavity end is funnel-form, the bell mouth at cavity two ends is relative, bell mouth place is provided with deceleration layer 3, as shown in Figure 3, deceleration layer 3 is network structure, stiffener 5 is also provided with in cavity, as shown in Figure 2, stiffener 5 offers oil guiding hole 6, oil guiding hole 6 on adjacent stiffening plates 5 is in being crisscross arranged, form cross-flow, slow down the flow velocity of heating oil.Heating oil enters the body of roll 4 cavity from the oil-in 2 roll shaft 1, the end of cavity is funnel-form, the runner that heating oil enters cavity broadens gradually, its flow is constant, therefore flow velocity reduces, lural deceleration layer 3 reduce further the flow velocity of heating oil, and heating oil is slowly flowed at the body of roll 4 cavity, and heat is fully used; When heating oil flows to oil-out 8 end, deceleration layer 3 and bell mouth slow down the flow velocity of heating oil again, add the time of staying of heating oil at the body of roll 4 cavity, improve the utilization rate of heating oil heat.

The edge of stiffener 5 both ends of the surface is equipped with protruding 7, and lateral surface and the cavity inner wall of protruding 7 are fitted, and add the width of stiffener 5 periphery, increases stiffener 5 and the contact area of the body of roll, improves the Rigidity and strength of roll.

With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can 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 right.
