Abstract
The utility model discloses a steam cover for a drying cylinder of a paper making machine. A steam heater is arranged in the steam cover. Since the steam heater which can maintain stability of the temperature in the steam cover is arranged in the steam cover, the temperature in the steam cover can be maintained relatively constant under the heating effect of the steam heater. Therefore, the steam cover is prevented from the impact of cold and wet environments in autumn and winter, the inner wall of the steam cover is prevented from condensation, and the quality of base paper is guaranteed.
Description
Technical field
The utility model relates to a kind of protective cover, refers to a kind of paper machine dryer vapour cover especially.
Background technology
Be the paper quality that guarantees that paper machine dryer is dried out, all be provided with the vapour cover in the paper machine dryer outside.But north cold weather autumn and winter, humidity is bigger in the paper machine room, and drying cylinder vapour cover internal temperature height, and drying cylinder vapour cover wet end is drawn into clammy air, adheres to the globule at vapour cover inwall easily, causes paper that the water droplet hole is arranged, and has a strong impact on original paper quality.
The utility model content
At the problem that prior art exists, the utility model provides a kind of paper machine dryer vapour cover that can prevent vapour cover inwall dewfall.
For achieving the above object, be provided with steam heater in the paper machine dryer vapour cover of the present utility model.
Further, described steam heater is welded as crooked shape for the multistage stainless steel tube.
Further, described steam heater is arranged on the vapour cover inwall at vapour cover wet end air inlet place.
Further, the shared steam source of the gas of described steam heater and paper machine dryer or have independently steam source of the gas.
Be provided with in the paper machine dryer vapour cover of the present utility model and keep the stable steam heater of vapour case temperature, under the heat effect of steam heater, can guarantee that the vapour case temperature is constant relatively, avoid the vapour cover influenced by cold wet environment of autumn and winter, in the problem of vapour cover inwall dewfall, guaranteed the quality of body paper.
Description of drawings
Fig. 1 is the structural representation of paper machine dryer vapour cover of the present utility model;
Fig. 2 is the schematic diagram of steam heater among Fig. 1.
The specific embodiment
As shown in Figure 1, schematic diagram for paper machine dryer and vapour cover thereof, drying cylinder 1 is cylindrical, drying cylinder 1 is by covering with the adaptive vapour cover 2 of drying cylinder 1, during paper machine dryer work, drying cylinder 1 rotation, paper tape wet end air inlet 21 from vapour cover 2 under the drive of drying cylinder 1 enters, cadre's air inlet 22 from vapour cover 2 is discharged, and under the heating of drying cylinder 1 wet pulp is dried.In order to prevent vapour cover 2 inwall dewfall, the globule drips on paper, at the vapour cover inwall at wet end air inlet 21 places a plurality of steam heaters 3 of arranging, keeps in the vapour cover 2 temperature constant relatively under the effect of steam heater 3, has reduced the probability of vapour cover 2 interior dewfall.Steam heater 3 not only can be arranged on wet end air inlet 21 places, also can be arranged on vapour cover 2 inwall optional positions, and can be provided with a plurality of in order to strengthen effect.
As shown in Figure 2, the curved pipe that steam heater 3 is welded into from beginning to end for the multistage stainless steel tube, stainless steel tube are provided with air inlet 31 and exhaust outlet 32, wherein feed high-temperature steam.The high-temperature steam source of steam heater 3 can be shared with drying cylinder 1, also can independently be provided with.
It is to be noted and any distortion of making according to the specific embodiment of the present utility model all do not break away from the scope that spirit of the present utility model and claim are put down in writing.
