Abstract
An electric heating paper dryer. The drying device is composed of a roller 1 and a rotating shaft 2, wherein an inner sleeve 4 is arranged on the inner side of a shell 3 of the roller to form a closed heat-conducting medium cavity 5, and heat-conducting oil and other media are filled in the cavity and are heated by an electric heating tube 6 to perform drying operation. Simple structure, high heat efficiency, no pollution and energy saving of over 40-70%.
Description
Technical field: the utility model is a kind of paper making equipment, promptly a kind of electric heating paper dryer.
Background technology: in paper-making process, after the paper moulding, need dry.Present drying plant is a drying cylinder, and drying cylinder is made of cylinder and rotating shaft, and the cylinder axle head is provided with air inlet pipe and blast pipe, joining with boiler forms the steam drying system, and during work, cylinder charges into steam, drum shell is in high hot state, carries out paper oven dry operation in rotation.The shortcoming of this mode is, in order to guarantee the temperature stabilization of cylinder, steam wherein must ceaselessly fill into and discharge, and the steam of discharging has then been thrown away in vain, and thermal loss is bigger, thereby has strengthened the cost of product.In addition, produced by fire coal because steam is many, coal-fired flue gas can pollute air, does not conform with environmental requirement.
Summary of the invention: the purpose of this utility model is that development is a kind of simple in structure, thermal efficiency height, free of contamination paper drying plant.Above-mentioned purpose is realized by following technical scheme: develop a kind of electric heating paper dryer, also be to constitute by cylinder, rotating shaft etc., different is, the shell inboard of said cylinder, it is a dielectric cavity that is used for the splendid attire heat-conducting medium, be provided with electrothermal tube in the dielectric cavity, be connected by electric slip ring between the power line of electrothermal tube and the power supply.
Said heat-conducting medium chamber is shell and the interior cover of shell inboard and the cavity that both ends of the surface form of cylinder.
In said cylinder the inside, motor and oil pump are housed, oil pump communicates with the dielectric cavity of cylinder by two branch oil pipes.
On said electrothermal tube power line, be provided with automatic temperature control switch.
On said cylinder, also be provided with regulator valve and warning device.
The both ends of the surface of cover and dielectric cavity outside is equipped with heat-insulation layer in said cylinder.
Said heat-conducting medium can adopt conduction oil.
The dryer that adopts such scheme to make, original steam is changed into heat conduction wet goods heat-conducting medium, boiler heating having become electrothermal tube heating, thereby structure is greatly simplified, thermal loss reduces, and electrothermal efficiency reaches more than 90%, and its expense can reduce 40-70%, also omit boiler and place simultaneously, avoided burning the coal contaminated environment.
Description of drawings: Fig. 1 is the front view of first kind of embodiment, and Fig. 2 is its left view, and Fig. 3 is the front view of second kind of embodiment, and Fig. 4 is its left view.
Among the figure as seen: cylinder 1, rotating shaft 2, shell 3, interior cover 4, dielectric cavity 5, electrothermal tube 6, heat-insulation layer 7, power line 8, electric slip ring 9, oil pipe 10, oil pump 11, oil pipe 12, gearbox 13, motor 14.
Embodiment: enumerate three embodiment.
First kind of embodiment: as shown in Figure 1 and Figure 2, this dryer also has a cylinder 1 and a rotating shaft 2, there is cover 4 in one deck shell 3 the insides of cylinder, outer 3 and interior cover 4 between formed the heat-conducting medium chamber 5 of a sealing, electrothermal tube 6 is equipped with in 5 the insides, heat-conducting medium chamber, the power line 8 of electrothermal tube 6 engages with the slip power supply electric slip ring 9 of axle 2 in the outside in heat-conducting medium chamber 5.In the heat-conducting medium chamber 5 li, fill conduction oil.During work, electrothermal tube improves the drum shell temperature heat-conducting oil heating, can carry out paper oven dry operation as existing drying cylinder cylinder.
For further saves energy, all be added with heat-insulation layer 7 at the interior cover 4 and heat conduction oil pocket 5 two ends of cylinder.
In addition, also be provided with attemperating unit and regulator valve and warning device on the cylinder.
Second kind of embodiment: shown in Figure 4 as Fig. 3, in the cylinder the inside, motor 14 is housed also, motor 14 drives oil pump 11 by gearbox 13, and oil pump 11 links to each other with two oil pipes, and two oil pipes all communicate with heat-conducting medium chamber 5.During work, two oil pipes can be squeezed into from another side with conduction oil from extracting out on one side, thereby can make the temperature equalization in the conduction oil chamber.This mode is applicable to the state that the high temperature and high speed trip changes.
The third embodiment, whole spaces of cylinder the inside are the heat-conducting medium chamber of sealing, this mode conduction oil large usage quantity, but temperature stability is good.
