Description
Technical field
The present invention relates to drying tunnel steam heater in corrugated machine, more specifically to a kind of steam heater.
Background technique
Currently, in corrugated paper board production line, single face corrugated board is after preheating, gluing and after facial tissue preheating, together into
Enter to carry out compound, compound corrugated board in drying tunnel by being passed through saturated vapor heater, heat is transmitted to corrugated board, will
Corrugated board bonding is formed and evaporates excessive moisture, and guarantee obtains qualified corrugated board.Conventional heater generally uses steel plate
Welding, inside is a chamber.Because processing technology limits, heating plate cannot be divided into several head and the tail communicate chamber, cause to steam
Vapour exchanges insufficient with splice device, and steam service efficiency is low, has some vapor to be discharged from the condensation mouth of a river, causes condensing water conduit pressure
Power is high, influences the normal hydrophobic and condensing hot air furnace of condensed water.Heater upper surface does not have fin simultaneously, and heat exchange area is limited,
In the case of corrugated board high speed operation, heter temperature compensation not enough, causes heter temperature to decline, corrugated board water content
Height, corrugated board bending deformation.
It is continuously improved, and fluting medium grammes per square metre gradually decreases, quality of corrugated is required more next with corrugation machine speed
It is higher.Corrugated board production speed improves, and heater and cardboard time of contact are shorter and shorter, and heater heat and heat is needed to mend
It fills in time, it is therefore desirable to improve heater, improve heater heat transfer efficiency；Body paper grammes per square metre lightweight, it is desirable that heater group by
It is deformed uniformly after heat, needs to improve heater structure and positioning method.Having heaters is heated evenly, and just can guarantee paperboard bonding
Sizing.
Summary of the invention
The purpose of the present invention is to the above-mentioned deficiencies of heater in current drying tunnel, and provide a kind of steam heater.
The present invention is made of a pair of of support base 1 and cavity 2, and it is fixed to be respectively equipped with located lateral face 3 and longitudinal direction in 2 bottom of cavity
Plane 4, and two positioning surface bottoms are respectively equipped with groove seam allowance, cavity 2 is horizontal by located lateral face 3 and longitudinal register face 4
Ground is mounted on support base 1, and is positioned by the groove seam allowance on located lateral face 3 and longitudinal register face 4, is equipped in cavity 2
One group of partition 5, one group of partition 5 divides the container into one group of chamber respectively, and each chamber head and the tail communicate, in each chamber inner top
It is respectively equipped with fin 6, has air intake 7 and condensation-water drain 8, air intake 7 and condensation-water drain in 2 bottom side of cavity
8 communicate with the chamber in cavity 2 respectively, another side end face of cavity 2 be equipped with one group of exhaust-valve 9, one group of exhaust-valve 9 respectively with
One group of chamber communicates.
The invention has the advantages that improved heater uses the principle of coil heat exchanger.If inner cavity is divided by partition
Dry room, each room are that head and the tail are connected to, and have fin on plate on the heaters, the saturated vapor being passed through is flowed along intracavitary each room
It is dynamic, sufficient heat exchange is carried out with hot plate.Since upper panel surface increases fin, increase upper plate absorption area 20%, guarantees upper plate
Absorb more heats, while fin is also beneficial to the water conservancy diversion of upper plate condensed water and falls, this arrangement enhances the utilization rate of steam,
Heater thermal energy is improved, is conducive to keep steady heater temperature when heater carries out heat exchange with cardboard again.
Improved heater is by positioning surface on the inside of hot plate, and two positioning surfaces of hot plate have a groove seam allowance,
The seam allowance of positioning surface 2 can control heater and laterally thermally expand；It is swollen to can control the longitudinal heat of heater for the seam allowance of positioning surface 10
Swollen, heating plate location structure improves, and effectively controls deformation of the heater under high temperature, high-pressure situations, while can also reduce and add
The deformation of hot device under the condition of self-weight guarantees heater normal operation, and every piece of heater texturing is uniform, is not in tradition
There is concave phenomenon in heater, and heater upper surface is normally contacted with corrugated board, improves heater heat transfer efficiency and cardboard matter
Amount.
Detailed description of the invention
Attached drawing 1 is schematic structural view of the invention.
Attached drawing 2 is the test figure structure schematic representation of attached drawing 1.
Attached drawing 3 is the A-A of attached drawing 1 to structural schematic diagram.

Specific embodiment
As shown in Figure 1, the present invention is made of a pair of of support base 1 and cavity 2, located lateral is respectively equipped in 2 bottom of cavity
Face 3 and longitudinal register face 4, and two positioning surface bottoms are respectively equipped with groove seam allowance, cavity 2 passes through located lateral face 3 and longitudinal direction
Positioning surface 4 is horizontally mounted on support base 1, and is positioned by the groove seam allowance on located lateral face 3 and longitudinal register face 4,
One group of partition 5 is equipped in cavity 2, one group of partition 5 divides the container into one group of chamber respectively, and each chamber head and the tail communicate, every
A chamber inner top is respectively equipped with fin 6, has air intake 7 and condensation-water drain 8, air intake 7 in 2 bottom side of cavity
Communicated respectively with the chamber in cavity 2 with condensation-water drain 8, another side end face of cavity 2 be equipped with one group of exhaust-valve 9, one group
Exhaust-valve 9 is communicated with one group of chamber respectively.
Usage mode: in use, saturated vapor is first entered heater by air intake, exhaust-valve 9 is opened simultaneously, is waited until
In heater after gas-liquid equilibrium, exhaust-valve is turned off.
Working method: saturated vapor enters heater by air intake, and steam is along each room circuitous flow, and and heater
Sufficient heat exchange is carried out, after saturated vapor discharges latent heat, condensed water is gathered on bottom plate along fin.Make in gravity and cavity pressure
Under, condensation-water drain is flowed to steam, condensed water is discharged from condensation-water drain, completes and the entire heat exchange of heater
Journey.Heater of the present invention, improves conventional heater structure, and steam circuitous flow in heater comes into full contact with, steam with hot plate
Latent heat discharges completely, improves the steam thermal efficiency；Also it avoided steaminess from entering condensing water conduit, and formed back pressure, and influenced normally to dredge
Water and condensing hot air furnace, plate increases fin on the heaters, increases hot plate heat exchange area, therefore increases hot in upper plate
Source is conducive to heater thermal compensation and increases heat output.
