Description
Technical field:
It is in particular a kind of for drying the mica paper of mica paper the utility model relates to the drying equipment of dry fiber web
Drying cylinder component.
Background technique:
In the prior art, in process for mica paper, the paper web of mica paper in forming area by
Fibrous suspension formed and first in roll squeezer or shoe press mechanically dehydration until the specific index of aridity, with
Afterwards using heated drying to the final index of aridity.
And the process of heated drying is mainly realized by drying cylinder, this drying is manufactured by steel, especially forged steel or cast steel,
Be made of cylindrical parts, be mainly used for the drying of paper web, tissue paper web or other fiber webs, thus also usually by with
Mica paper is dried in mica paper manufacturing field.This cylindrical dryer is closed in two side ends, and steaming is consequently formed
Steam chest.It uses condensable gaseous state heat-carrying agent (most often using steam as heat medium) to heat outside the vaporium, is then introduced into
In vaporium, undergone phase transition by radiating in fiber web drying process, and condensate liquid is consequently formed.Under common machine speed,
The condensate liquid is since centrifugal force is in the condensation pendular ring being closed in drum shell, and paper web, tissue paper web or other fibers
Web contacts hot drying cylinder by wrapping mode and realizes drying by the energy of the steam release of condensation inside drying cylinder.But
This to there is a problem that drying efficiency is not high by way of heating to drying cylinder steam medium, energy-efficient performance is poor, and
Steam is easy leakage, and the general steam that generates can be consumed lot of materials, be discharged bulk gas, meeting by the way of combustion heating
Environment is affected greatly.
Utility model content:
The technical issues of the utility model is solved is to provide a kind of mica paper drying cylinder component, to solve above-mentioned technology back
The defects of scape.
The technical issues of the utility model is solved is implemented with the following technical solutions:
A kind of mica paper drying cylinder component, including circulation line drying cylinder (1) and be connected with drying cylinder, which is characterized in that institute
Stating drying cylinder is the hollow cylinder made of steel, especially forged steel or cast steel, and the hollow cylinder both ends are by being equipped with oil pocket (2) and carrying out
Closing connects rotary joint (3) by pipeline in the middle part of drying cylinder, while rotary joint is followed with electrothermal chamber and oil circulating pump formation
Ring piping connection；And using conduction oil as heat-carrying agent in the circulation line and the hollow cylinder, meanwhile, in circulation pipe
Road further include have the solid-state relay of an oil circulating pump and a power adjustable, and rotary joint downstream line and circulation
Pipeline is separately connected the both ends of high tank (7) between oil pump (5) and electrothermal chamber (6).
In the present invention, the dosage of the conduction oil is to fill up entire circulation line and 1/4~1/3 capacity
Subject to drying cylinder.
In the present invention, the circulation line in the upstream line of access oil circulating pump and picks out solid-state relay
A temperature sensor is all connected in the downstream line of device, to carry out to the temperature conditions in circulation sections different in circulation line
Monitoring.Its control principle are as follows: electrical control cabinet starts oil circulating pump and heating agent conduction oil is driven circulation, and oil goes out from oil circulating pump
Hydraulic fluid port successively exports by electric heating pack, rotary joint oil inlet, oil pocket to oil pocket, rotary joint center flowline and pump into
Hydraulic fluid port.So constitute a closed-loop flow.Next heating system could be opened, because anti-dry and local temperature are excessively high, oil pump
Electrical interlocks are provided with heater, at this moment solid-state relay is reached in the given starting voltage signal of oil outlet temperature controller
Afterwards, start to export electric current to heat-generating pipe heating conduction oil, until oil temperature reaches setting operating temperature, temperature controller is given
Starting voltage gradually decreases, and the output electric current of solid-state relay also slowly reduces, and heat-generating pipe heating power also becomes smaller therewith, also
It is to say that solid-state relay is gradually closed when temperature is high, when temperature is low, just slowly opens, forever temperature automatic control in a temperature
The operating temperature or so for spending controller setting provides given drying thermal energy to mica paper dry on drying cylinder is constantly transmitted to,
And the setting temperature value is determined according to the production technology and paper sheet thickness of mica paper to be dried, preferably 175 DEG C~180 DEG C.
Preferably, the hollow structure volume of the drying cylinder is 4.2m3, the pump power of the oil circulating pump is
7.5KW, and the general power of the solid-state relay is 180KW, including two groups or three groups independent controls and power is consistent
Semiconductor thyristor is become as heating unit, solid-state relay by controlling the unlatching group number of heating unit to control its power
Change.
Preferably, when conduction oil oil mass has consumption, oil is filled by high tank by filling oil pump (8), then by height
Position oil groove passes through the pipeline that is connected thereto to corresponding position.
The utility model has the advantages that
1, a kind of mica paper drying cylinder component described in the utility model carries out drying cylinder bucket using sensor technology and conduction oil
The control of face temperature, by thermally conductive oil temperature in temperature sensor acquisition system, and controls solid-state relay and adds to conduction oil
Heat, to automatically control the operating temperature in drying cylinder bucket face, when sensor can carry out temperature automatic constant and avoid using steam
The switch steam boiler air valve for wanting artificial not timing, alleviates labor intensity, improves production efficiency.
2, economical environment-protective, first, boiler in addition to fuel consumption greatly other than, it is also essential with water, with oil heating do not have to one drop
Water, second, with boiler per tour will special fireman, oil oven heat automatically can be achieved it is unattended, environmental protection aspect without exhaust gas,
Useless cigarette, discharge of wastewater.
It 3, is not in high temperature, the high pressure even danger of explosion because using the normal pressure method of operation.
4, long service life, maintenance cost and allowance for depreciation are low.
5, in terms of production scheduling, when supplying steam with boiler heat supplying, an equipment supplies whole paper machines.With oil cylinder heat supply
Afterwards, whole respective independent heatings, reduce the passive situation of one Ting Quan factory of boiler shutdown, and personnel are not enough or when repair apparatus stops one
When platform or more machines, corresponding heating equipment can be also shut off, but boiler is uncontrollable.
6, occupied space is few, and to place without particular/special requirement, pipeline path is short, sets up simple, complete machine installation, installation week
Phase is short, without the installation of special commission installation company.
In conclusion substitute traditional boiler heat supplying with conduction oil heating system, although unit cost is slightly higher, from long-range
From the perspective of, it will be environmentally friendly, safety is taken up an area, and manipulation, production scheduling and maintenance of equipment depreciation etc. account for, society
Before benefit and economic benefit are much larger than transformation.
