Abstract
The utility model relates to a drying hood for production of household paper, which covers the top of a dryer, the drive side top of the drying hook is provided with two parallel steam holes as a steam inlet and a steam outlet, and four coils which are made of stainless steel tubes are arranged beside the steam holes, and are fixed on the lowest bottom in the drying hook. Compared with the prior art, the drying hood has the advantages that: the structure is simple, the application range is wide, the drying hood is convenient to operate, only four stainless steel steam tubes need to be mounted, and the drying hood is safe and reliable; the drying hood can timely bring away a great deal of wet steam evaporated in the process of drying a wet paper web by the dryer, increase the drying efficiency and effectively reduce the phenomenon of surface drip holes, consequently, the product quality is stabilized, the frequent paper-breaking phenomenon of a paper machine, which is caused by continuous big drip holes, is reduced, and the stability of output capacity is guaranteed.
Description
Technical field
The utility model relates to papermaking apparatus, especially relates to the oven dry gas hood of a kind of productive life with paper.
Background technology
Paper machine in the winter time in the production process regular meeting dripping phenomenon occurs and cause bad product.Reason is that the gas hood internal-external temperature difference is bigger, a large amount of steam are run into the lower gas hood inwall of temperature and are formed the globule, the increasing globule gathers the gathering that produces condensed water, drops onto on the paper that is pasting drying cylinder when arriving the gas hood minimum point, and causing has the hole of dripping on the page.The hole of dripping not only makes the non-conformity of quality of paper close requirement, and the big hole of dripping also can cause frequently disconnected paper, influence the paper machine ordinary production, causes the production capacity loss, therefore is badly in need of the problem that solution causes paper to have because of gas hood drips to drip the hole.
The utility model content
The purpose of this utility model is exactly to provide a kind of simple in structure for the defective that overcomes above-mentioned prior art existence, and is applied widely, easy to operate, the productive life that drying efficiency the is high oven dry gas hood of paper.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of productive life oven dry gas hood of paper, be located at the top of drying cylinder, it is characterized in that, the transmission side top of this oven dry gas hood offers that two parallel pores enter the hole as steam and steam portals, sidepiece at pore is provided with the four road coil pipes that curve through stainless steel tube, and this four roads coil pipe is fixed on the bottommost in the oven dry gas hood.
It is 21mm that described steam advances the diameter that hole and steam portals.
It is 180mm that described steam advances hole and the steam distance between portalling.
The diameter of described stainless steel tube is 20mm.
The length of described four road coil pipes is 2900mm, and width is 60mm.
Compared with prior art, the utlity model has following advantage:
(1) simple in structure, applied widely;
(2) easy to operate, only need that 4 stainless steel steam pipes are installed and get final product, safe and reliable;
(3) in time take away a large amount of wet steam that evaporate in the cylinder dried wet web process, improve drying efficiency, effectively reduce the drip phenomenon in hole of paper, stablized product quality;
(4) reduce the frequently disconnected paper of the paper machine that causes because of the continuous big hole of dripping that occurs, guarantee that production capacity is stable, realizes ordinary production.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
1 is that drying cylinder, 2 is that drying cylinder gas hood, 21 is that pore, 22 is that coil pipe, 3 is airduct among the figure.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of productive life oven dry gas hood of paper, be located at the top of drying cylinder 1, its structure as shown in Figure 1, the pore 21 that it is 21mm that the transmission side top of this oven dry gas hood 2 offers two parallel diameters, enter the hole as steam respectively and steam portals, it is 180mm that steam advances hole and the steam distance between portalling, being provided with through diameter at the sidepiece of pore 21 is that the four road coil pipes 22 that curve of the stainless steel tube of 20mm are as steam pipe, this four roads coil pipe 22 is fixed on the bottommost in the oven dry gas hood 2, the length of four road coil pipes 22 is 2900mm, width is 60mm, and logical at last upward steam gets final product.The utility model mainly utilizes the heat of steam pipe with condensate evaporation, is in time taken away by the blower fan that is connected on the airduct 3 again, efficiently solves the phenomenon that the little globule gathers at oven dry gas hood 2 inwalls.
After having added the four road coil pipes 22 that are connected with steam, the wet steam that wet web comes out is difficult for being condensed into the globule, also can be flashed to water vapour once more even there is condensed water to form, and is and then taken away by blower fan.Solve condensed water and be accumulated into the problem that the big globule drops onto paper.
Claims (5)
