The specific embodiment
Shown in Fig. 1 to 5, condensed water of the present utility model is discharged and retracting device, be arranged on the end of separating out of tilting pipeline baker roller 18, the axle tube sealing 5 that connects the cast steel shaft collar 4 of baker roller 18 and is communicated with cast steel shaft collar 4 120 is spent angles and is arranged on the outflow pipeline that baker roller 18 separates out the dip-tube group of end and can regulate air pressure and forms at interval respectively by three groups.The injection end of described tilting pipeline baker roller 18 comprises the initial steam pipeline 11 and the material inlet 12 of central authorities.
Described dip-tube group comprises two tap holes 1, a collecting tank 2 and a pumping elbow pipe 3.Described tap hole 1 ring is located at described baker roller 18 and separates out on the barrel of end.Described collecting tank 2 is arranged on described baker roller 18 and separates out on the outer wall of end, is communicated with described tap hole 1.One end of described pumping elbow pipe 3 connects described collecting tank 2, and the other end connects described cast steel shaft collar 4; The bending direction of described pumping elbow pipe 3 is identical with the gyratory directions of described baker roller 18.Described outflow pipeline comprises the condensed water pressure duct 9 that has valve 14, built on stilts pipeline 10 of condensed water and the threeway branched pipe 6 that has valve 15, and this threeway branched pipe 6 connects described axle tube sealing 5, described condensed water pressure duct 9 and the built on stilts pipeline 10 of condensed water respectively.
In the process that reality is used, the particularly important is and avoid in condensate line, occurring the backflow situation.The backflow situation produces because of the pressure reduction between baker roller 18 and condensed water pressure duct 9.It can cause condensed water to gather in baker roller 18, and condensed water gathers and then causes the drive motor overload and may cause that drive motor is malfunctioning.When the power consumption of drive motor rises suddenly, should temporarily open the gate valve 15 of the built on stilts pipeline 10 of described condensed water and the safety excess pressure valve is checked.
As shown in figure 15, described pumping elbow pipe 3 is U type pipes, the length difference of its two side branch, and the pipe 34 of drawing money on credit connects described collecting tank 2, and short arm 35 connects described cast steel shaft collar 4.
Shown in Fig. 6 to 14, first pumping elbow pipe 31, second pumping elbow pipe 32 and the 3rd pumping elbow pipe 33 in the utility model all is U-shaped pipes that a side is long, a side is short, effectively prevent the backflow situation of condensed water in the baker roller rotary course, guaranteed that condensed water flows among the cast steel shaft collar incessantly in the rotary course of pipeline baker 360 degree.
Described condensed water is maked somebody a mere figurehead pipeline 10 drainers 17 in parallel, and the two ends of described drainer 17 are respectively equipped with valve.
Described threeway branched pipe 6 connects a ventilation valve 7 and only enters described threeway branched pipe 6 for air check valve 8.
Described ventilation valve 7 is used for baker is ventilated and exhaust, promptly is used for the cooling preheating in other words of described baker.As ventilation valve 7 automatics blow off valve valve air relief, check valve 8 has been installed, if be lower than atmospheric pressure in baker, so described check valve 8 just responds, and puts into air.In addition, on the roll circumference of the outside of described baker, three condensed water dump valves are arranged on discharge side.Can when baker is shut down, condensed water be discharged by these three condensed water dump valves.
Using method of the present utility model is as follows:
In service in standard, only open the gate valve 19 of described initial steam pipeline 11 and the gate valve 14 of condensed water pressure duct 9.Condensed water flows in the condensed water collecting box by condensed water pressure duct 9 and pushes back in the boiler room therefrom.
When shutting down, baker the steam in baker still need be discharged in the built on stilts pipeline of described condensed water.Therefore the gate valve 14 that must close condensed water pressure duct 9 earlier just can be opened the gate valve 15 of the built on stilts pipeline 10 of described condensed water afterwards.In this case, must in advance the admission gate valve on the charging side of baker (being the gate valve 19 of initial steam pipeline 11) be closed.In case when steam flowed out, steam pressure was lower than atmospheric pressure, that just independently opens described check valve 8 (being the ventilation valve of unidirectional air inlet), makes air to flow in the baker.
When starting baker once more, open the bypath valve 20 in the initial steam bypass line.Close condensed water simultaneously and flow out the valve 14 of condensed water pressure duct 9 in the pipeline, the valve 15 of the built on stilts pipeline 10 of condensed water and the valve 13 of drainer 17 leading portions.When the starting beginning, only open described ventilation valve 7 at discharge side.Flowing into the air that the initial steam in the baker will enter when baker is shut down in this start-up period during this period squeezes out from baker roller 18.Then, as replenishing of ventilation valve 7, also open the valve 13,16 of drainer 17 front and back.It is necessary doing like this, because the valve 19 in the initial steam pipeline 11 often continues to open, until preheating is finished.If also only flow out pure steam from described ventilation valve 7, that is just closed it.
The condensed water that then produces in warm-up phase in baker flows in the built on stilts pipeline 10 of described condensed water by the valve 13,16 of drainer 17 and front and back thereof.Guarantee do not have steam to flow in the described built on stilts pipeline 10 by the mode of inserting described drainer 17.Significantly reduce the condensed water loss thus between warming up period, energy savings helps the protection to environment.Guarantee that simultaneously the steam pressure in the baker slowly rises under the situation of valve regulated targetedly not carrying out in warm.If will there not be the baker of drainer 17 to put into operation in contrast, that just must regulate pressure in the baker by the valve 15 of the built on stilts pipeline 10 of condensed water.
After the baker preheating reaches operating pressure, close the valve 13 (valve 15 of the built on stilts pipeline 10 of condensed water in other words) of described shutoff drainer front end and open gate valve 14 in the described condensed water pressure duct 9.Open the valve 19 in the described initial steam pipeline 11 simultaneously and close bypath valve 20 in the described bypass line.So far, baker is in the operative condition.
