Abstract
The present invention discloses a hot-pressing roller for paper-making machine. It includes a metal roller self-body, every end of two ends of said metal roller self-body is equipped with a roller shaft, the external peripheral surface of said metal roller self-body is covered with a layer of stainless steel material, and the external surface of the described stainless steel layer is covered with a ceramic layer, and in the interior of said metal roller self-body is set a heating device for raising roller surface temperature.
Description
Technical field
The present invention relates to the thermal press rolls that paper machine is used.
Background technology
The effect of paper machine press section is to make the dehydration of l Water Paper page or leaf.Accompanying drawing 4 is depicted as the paper machine pressing device, and l Water Paper page or leaf 6 advances people's first nip between rubber roll C and the suction press roll B, and a moisture part of extruding is taken away with woollen blanket C1, B1, and a part is taken away through the vacuum of suction press roll B; Page enters second nip, directly meets main press roller A, through the pressurization of suction press roll B and main press roller A, and dehydration rapidly, a moisture part is taken away by woollen blanket B1, and a part is taken away by suction press roll B; Page enters the 3rd nip with main press roller A, and through the pressurization of the rubber roll D and the main press roller A of the 3rd nip, moisture is taken away with woollen blanket D1 then, and page is drawn press section, finishes the dehydration of press section.
At the paper machine press section, there are following four kinds of measures can improve the mass dryness fraction that page leaves press section: 1, to increase nip pressure; 2, increase the time of staying of nip; 3, improve the page temperature; 4, reasonable vacuum.Wherein increase the pressure of pressor areas and the limitation that adopts reasonable vacuum to possess skills, just can not continue to increase work efficiency after adjusting to optimum state, the time of staying that increases nip then can be reduced production efficiency greatly, and removes the technical barrier that moisture content becomes the puzzlement engineers and technicians always by the temperature that the temperature that improves pressure roller improves page then.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, thermal press rolls for paper machine that dewatering efficiency is high.
For achieving the above object, technical scheme of the present invention is: thermal press rolls for paper machine, comprise the metallic roll body, be fixedly installed on the roll shaft at described metallic roll body two ends, be coated with the stainless steel bed of material on the external peripheral surface of described metallic roll body, the extexine of the described stainless steel bed of material is coated with ceramic layer, is provided with the heater that improves roll surface temperature in the described metallic roll body.
As a kind of improvement, described heater comprises and is arranged in the metallic roll body and the some heat medium circulation passages parallel with its axis that described roll shaft is provided with the thermal medium inlet and the thermal medium that are communicated with the heat medium flow circulation passage and exports.
As a kind of further improvement, described thermal medium inlet and thermal medium outlet are arranged on the roll shaft of metallic roll body one side, and the described roll shaft that is arranged on metallic roll body opposite side is provided with the connection chamber that is communicated with thermal medium feed pathway and liquid outlet channel.
Owing to adopt technique scheme, thermal press rolls for paper machine, comprise the metallic roll body, be fixedly installed on the roll shaft at described metallic roll body two ends, be coated with the stainless steel bed of material on the external peripheral surface of described metallic roll body, the extexine of the described stainless steel bed of material is coated with ceramic layer, is provided with the heater that improves roll surface temperature in the described metallic roll body; Page 6 advances people's first nip between rubber roll C and the suction press roll B, and a moisture part of extruding is taken away with woollen blanket C1, B1, and a part is taken away through the vacuum of suction press roll B; Page enters second nip, directly contacts main press roller A, through the pressurization of suction press roll B and main press roller A, under the situation that the page temperature raises, moisture viscosity descends, dehydration rapidly, a moisture part is taken away by woollen blanket B1, and a part is taken away by suction press roll B; Page enters the 3rd nip with main press roller A, and then through the pressurization of the rubber roll D and the main press roller A of the 3rd nip, the page temperature raises, moisture viscosity descends, and moisture is taken away with woollen blanket D1, and page is drawn press section, finishes the dehydration of press section.The present invention has improved the temperature of page, helps the page dehydration, thereby improves the mass dryness fraction that page goes out press section, and has therefore improved the operating efficiency and the product quality of paper machine.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, thermal press rolls for paper machine, comprise metallic roll body 1, be fixedly installed on the roll shaft 4,5 at described metallic roll body 1 two ends, be coated with the stainless steel bed of material 2 on the external peripheral surface of described metallic roll body 4,5, the extexine of the described stainless steel bed of material 2 is coated with ceramic layer 3, is provided with the heater that improves roll surface temperature in the described metallic roll body 1.
Described heater comprises and is arranged in the metallic roll body 1 and some heat medium circulation passage as, the b parallel with its axis that described roll shaft 4,5 is provided with thermal medium inlet 41 and the thermal medium outlet 42 that is communicated with heat medium flow circulation passage a, b.
Described thermal medium inlet 41 and thermal medium outlet 42 are arranged on the roll shaft 4 of metallic roll body 1 one sides, and the described roll shaft 4 that is arranged on metallic roll body 1 opposite side is provided with and is communicated with thermal medium feed pathway a1, a2, a3, a4, a5, a6 and liquid outlet channel b1, b2, b3, b4, connection chamber ab1, the ab2 of b5, b6, ab3, ab4, ab5, ab6.
Described metallic roll body 1 adopts the cast iron manufacturing, bore the system aperture at vertical periphery, be used for by deep fat with the heating roll body, roll body surface spray aluminum oxide or zirconia ceramics, its effect one is that abrasion resistance is good, the 2nd, ceramic surface has the micropore of 2-7%, can prevent from that page is adsorbed on to be difficult on the roll body peel off.Spindle nose and bearing are equipped with in the thermal press rolls two ends, and wherein transmission side is equipped with into adapter.The deep fat heating can be adopted the mode of steam preheating, electrothermal tube heating.
