Description
Technical field
The utility model is related to rotary press field, more specifically, it relates to a kind of rotary press chilling roll
Anti-condensation system.
Background technology
The cooling unit configured on rotary press is one of indispensable main accessories, and its main function is by from drying oven
In the paper of high temperature out cool rapidly.Cooling unit is in respect of six chilling rolls, and cooling water is not in roller when equipment is run
Disconnected circulation, the heat in the paper being in contact with it is taken away, but because of chilling roll surface temperature（12℃）Less than environment temperature
（25-30℃）, the steam in air will constantly condense into the globule on chilling roll surface.When equipment is run, condensed water can not
It is disconnected to be taken away and evaporated by the paper of high temperature, and when within the short a few minutes for shutting down plate change, because cooling water is rested in roller,
Therefore condensed water may proceed to produce, and soaks static paper onto a chilled roll, among other applications, paper will be broken when rotary press starts again,
The paper soaked is even set to enter plug bad lateral paper guide in folding machine.So just must splicing again, or get rid of before start leaching
Wet paper, this needs 2-3 people to cooperate, and takes about 5 minutes, and changes lateral paper guide and be then additionally required four minutes, and this gives birth to board
Production efficiency and paper all cause larger waste.
Utility model content
The purpose of this utility model is to provide a kind of rotary press chilling roll anti-condensation system, can avoid cooling down
Condensed water is condensed on roller.
Above-mentioned purpose of the present utility model technical scheme is that：
A kind of rotary press chilling roll anti-condensation system, including chilling roll, it is connected to entering for chilling roll two ends
Water pipe and outlet pipe, water inlet pipe and outlet pipe connect cold flow pipe, and water inlet pipe and outlet pipe are also respectively connected with hot-fluid pipe, two heat
Flow tube is connected to the boiler formation loop of storage hot water, water inlet pipe and cold flow pipe, the intersection of hot-fluid pipe and outlet pipe with
Cold flow pipe, the intersection of hot-fluid pipe are provided with for gating water inlet pipe, outlet pipe, cold flow pipe to form cooling channel, or choosing
Logical water inlet pipe, outlet pipe, hot-fluid pipe are to form the sluice valve of heating circuit, and heating circuit is provided with water pump, the rotary printing
Machine chilling roll anti-condensation system also includes waste heat recovery thermal source, waste heat recovery thermal source connection heat-exchange tube, heat-exchange tube position
In in boiler.
Using such scheme, when rotary press is normally run, sluice valve gating water inlet pipe, outlet pipe, cold flow pipe are cold
Water normal circulation, chilling roll cools rapidly to high temperature paper, when rotary press is shut down, and sluice valve gates water inlet pipe, gone out
Water pipe, hot-fluid pipe constitute heating circuit, drive the hot water in boiler to be circulated in heating circuit by water pump, to chilling roll plus
Heat, reaches chilling roll surface temperature basically identical with ambient temperature, non-condensing condensed water, paper is kept drying, improves
Production efficiency, reduction paper waste and cost of parts.
Further, water inlet pipe and cold flow pipe, the sluice valve of the intersection of hot-fluid pipe are one-in-and-two-out magnetic valve, outlet pipe with
Cold flow pipe, the sluice valve of the intersection of hot-fluid pipe enter one for two and go out magnetic valve.
Further, waste heat recovery thermal source is baker.
Further, heat-exchange tube is serpentine coil.
In summary, the utility model has the advantages that：The principle condensed to the cold from condensed water, by setting
Put heating water tank, water pump, hot-fluid pipe, shut down when to chilling roll carry out heating be allowed to surface reach it is consistent with ambient temperature,
Avoid condensing water condensation from heat, improve production efficiency.

Embodiment
As shown in figure 1, a kind of anti-condensation system of rotary press chilling roll 1, including be arranged in rotary press
Chilling roll 1, chilling roll 1 is used to quickly cool down high temperature paper, and the two ends of chilling roll 1 connect water inlet pipe 11 respectively
With outlet pipe 12, water inlet pipe 11 connects cold flow pipe 2 with two outsides of outlet pipe 12, and cold flow pipe 2 is passed through water temperature for 12 degrees Celsius
Cold water, when water inlet pipe 11, outlet pipe 12, cold flow pipe 2 turn on when constitute cooling channel, chilling roll 1 is quickly cooled down.
The junction of water inlet pipe 11, outlet pipe 12 and cold flow pipe 2 is also associated with hot-fluid pipe 3, and two hot-fluid pipes 3 are connected to storage
Deposit hot water（30 degrees Celsius）The formation of boiler 4 loop, be provided on loop providing the water pump 5 that hot water flows driving force, enter
Water pipe 11 is connected with the intersection of cold flow pipe 2, hot-fluid pipe 3 by one-in-and-two-out magnetic valve 6, outlet pipe 12 and cold flow pipe 2, hot-fluid
