Description
Technical field
The utility model relates to papermaking equipment field, particularly relates to the drying device in papermaking dry operation.
Background technology
In papermaking dry operation, dry temperature, humidity, uniformity etc. all can have influence on the quality of page, for example excess Temperature or the too fast meeting that heats up make page overdrying easily occur pleat, and can affect smoothness, tightness and the glossiness of the page of press polish operation below, the inhomogeneous meeting of paper page drying position causes shrinks the inhomogeneous part partial relaxation that compacts and also can easily produce pleat, therefore will under applicable temperature, damp condition, be dried, the page of producing could be more attractive in appearance.
At present, the drying device structure using in common paper machine has multiple, increases structure for addressing the above problem at the architecture basics of former drying device again, drying device is become increasingly complex, long-term use easily hidden and polluted page, installs not easy care, and manufacturing cost is also more and more higher.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, low cost of manufacture, and the good paper machine drying box of drying effect.
For achieving the above object, the technical solution of the utility model is: a kind of paper machine drying box, comprise casing, be arranged on many air-out roll shafts in casing, around dryer felt and electric control system on air-out roll shaft, the two ends of described air-out roll shaft are arranged on respectively on the two side that casing is relative, on another relative two side of described casing, offer respectively input port and delivery outlet for dryer felt input and output, described casing comprises dry section and Hui Runqu, in described dry section, be provided with the temperature sensor that connects electric control system, the air-out roll shaft of described dry section connects air blast output hot blast, the casing top of described dry section and Hui Runqu is offered suction opeing and is connected air exhauster, described air blast connects frequency converter, described frequency converter is connected with electric control system, the air-out roll shaft of described Hui Runqu connects air blast output cold wind.
Separate by vertical clapboard in the Yu Huirun district, dry section of described casing, and described vertical clapboard offers delivery port.
Described air-out roll shaft is interior outer double-layer structure, and internal layer and outer interval arrange, and on internal layer and outer field sidewall, are evenly distributed with respectively multiple exhaust vents.
Bottom, described dry section is distributed with many warm-air pipes, offers multiple vents on described warm-air pipe, and one end of described warm-air pipe is provided with valve and is connected with air blast.
By adopting technique scheme, the beneficial effects of the utility model are: pass through said structure, page under the leading of dryer felt from input dry section, casing input port, with dryer felt on air-out roll shaft, hot blast is delivered into air-out roll shaft by air blast, discharge page is dried by air-out roll shaft, then discharge from the suction opeing at casing top, owing to being provided with temperature sensor in casing, can monitor the temperature in casing and be transferred to electric control system, when temperature overrate, electric control system regulates the motor speed of air blast to reduce the conveying capacity of hot blast by controlling frequency converter, so just can avoid excess Temperature dry too fast, drying effect is better, then, run into cold wind because also enter Hui Runqu with hot gas on page, make page surface have the effect of getting damp, be conducive to like this reach better the calendaring effect in next step press polish operation.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of paper machine drying box of the utility model embodiment.
Detailed description of the invention
Below by describing in conjunction with the accompanying drawings and embodiments embodiment of the present utility model in detail, to of the present utility model fully understanding.
As shown in Figure 1, a kind of paper machine drying box, comprise the drying box 1, the two ends that are divided into 11He Huirun district, dry section 12 be arranged on respectively many air-out roll shafts 2 on the interior relative two side of casing 1, around the dryer felt 3 on air-out roll shaft 2, be arranged on temperature sensor 4 on casing 1 dry section 11 inwalls, connect the electric control system (not shown) that air exhauster 6 that suction opeing that hot air duct offers to the air blast 5 of air-out roll shaft 2 heat air deliveries of dry section 11, with 12 casing tops, 11He Huirun district, dry section is connected and control drying box 1 turn round.
On the 11 head end box body sidewalls of described dry section, offer input port 13, on described Hui Run district 12 rear end wall box, offer delivery outlet 14, dryer felt 3 is inputted from input port 13, on air-out roll shaft 2, exports from delivery outlet 14; Described casing is also separated by vertical clapboard 15 between 1 11Yu Huirun district of inner drying district 12, offers the delivery port 16 passing for dryer felt 3 on vertical clapboard 15.
Described temperature sensor 4 connects electric control system; What the air-out roll shaft 2 of described dry section 11 connected is, and hot air duct carries is hot blast, Er Huirun district 12 air-out roll shaft 2 connect what be that cold air duct carries is cold wind; Described air blast 5 connects frequency converter 7, and frequency converter 7 is connected with electric control system.
Described air-out roll shaft 2 is interior outer double-layer structure, and internal layer 21 arranges with outer 22 intervals, on internal layer 21 and outer 22, is evenly distributed with respectively multiple exhaust vents 23.11 bottoms, described dry section are also distributed with many warm-air pipes 8, offer multiple vents 81 on described warm-air pipe 8, and one end of described warm-air pipe 8 is provided with valve 9 and is connected with air blast 5.
Vertical clapboard 15 between 11Yu Huirun district, described dry section 12 can further effectively prevent that the hot blast in 11He Huirun district, dry section 12 from intersecting with cold wind, avoids producing condensation vapor and causes dripping phenomenon, makes paper page drying position inhomogeneous; The double-decker of described air-out roll shaft 2, can make hot blast or cold wind disperse output, is not concentrated in somewhere output, so also can be more even to the dry or Hui Run of page; For will be dried the higher page of some humidity time, increase the dispersion face of casing 1 interior hot blast, can pass through Open valve 9, the hot blast that air blast 5 is carried is distributed in many warm-air pipes 8 and discharges.
When work: page is inputted dry section 11 from casing 1 input port 13 under the leading of dryer felt 3, with dryer felt 3 on air-out roll shaft 2, hot blast is delivered into air-out roll shaft 2 and warm-air pipe 8 by air blast 5, discharge page is dried by air-out roll shaft 2 and warm-air pipe 8, then discharge from the suction opeing at casing 1 top, temperature sensor 4 is monitored the temperature in casing 1 and is transferred to electric control system, when temperature overrate, electric control system regulates motor 5 rotating speeds of air blast 5 to reduce the conveying capacity of hot blast by controlling frequency converter 7, then, enter Hui Run district 12, run into because also enter Hui Run district 12 with hot gas on page the cold wind of exporting on output roll shaft 2, make page surface have the effect of getting damp, cold wind is discharged from the suction opeing at casing 1 top, then page output enters next papermaking operation.
Be only this origination techniques content preferred embodiment in sum, be not used for limiting practical range of the present invention, the equivalence that Fan Yiben author content is done changes and modifies, and all should belong to the technology category that this creation is advocated.
