Description
Technical field:
The present invention relates to a kind of discharger of condensed water, particularly relate to a kind of discharger of high speed paper machine drying cylinder condensed water, belong to the paper making equipment field.
Background technology:
Condense into condensed water after the steam heat release in the paper machine dryer, condensed water will accumulate in the drying cylinder bottom when drying cylinder rotating speed was low, under the drive of drying cylinder inwall, will rotate to condensed water to a certain degree when rotating speed is high, form one deck water ring at the drying cylinder inwall, the heat transfer of obstruction drying cylinder with drying cylinder.Traditional processing method is: install to destroy bar (flow-disturbing rod) to destroy the formation of water ring at the drying cylinder inwall, make condensed water accumulate in the drying cylinder bottom, re-use the siphon head and utilize the drying cylinder inside and outside differential pressure that condensed water is discharged cylinder to see (referring to Fig. 1 and Fig. 2) outward.Though conventional method can be destroyed water ring, make inwall can not form continuous water ring, effect and not obvious on high-speed paper machine.Raising along with rotating speed, the destruction bar can drive condensed water and rotate with drying cylinder, form the thick discontinuous water ring of one deck 10～20mm at the drying cylinder inwall, siphon pipe could draining when only condensed water gathers certain depth in drying cylinder in addition, so just has a strong impact on the heat-transfer effect of casing wall.The conventional method drying cylinder must will produce the part vapour losses like this in that ability draining under the condition of inside and outside differential pressure is arranged in addition.
Summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, a kind of paper machine drying cylinder condensate water extraction device is provided, this device strikes off moisture film from the drying cylinder inwall, in time removes condensed water, can not produce water ring; By gravity drainage, do not utilize pressure reduction, can increase substantially heat transfer efficiency, reduce steam consumption.
The technical scheme that the present invention is taked for the technical solution problem is:
A kind of high speed paper machine drying cylinder condensate water extraction device, comprise drying cylinder, the transmission side of described drying cylinder end cap is provided with swivel joint and drainpipe, the inboard of described drying cylinder two ends end cap is respectively arranged with a bearing, a central tube is installed between two bearings, be connected for rotary type between described central tube and two bearings, the one end is connected and is communicated with the drainpipe that runs through end cap, its other end is a cecum, be arranged at intervals with row's conduit on the axial tube wall of described central tube, all outer end of conduit all are connected and are communicated with header tank, and the outer end of described header tank is provided with Wiper blade, and the outer end of this Wiper blade contacts with described drying cylinder inner surface.
The quantity of described conduit is more than two.
Each conduit all is made up of two arms, the upper end of two arms is connected and is communicated with header tank respectively, is connected and is communicated with described central tube after its lower end crosses, perhaps, the lower end of two arms is connected and is communicated with central tube respectively, and two tie points are positioned on the same radial section of described central tube.
One is linear pattern in described two arms, and another is a broken line shape.
The shape of cross section of described header tank is the U type, and described Wiper blade is made by the wear-resistant flexible material, and its lower side is fixed on the outer side edges of described header tank, its upper side edge and described drying cylinder inner surface Elastic Contact.
High speed paper machine drying cylinder condensate water extraction device of the present invention, its Wiper blade is fixed on the header tank, makes of softer and high-abrasive material, and the drying cylinder that neither weares and teares can use for a long time again and needn't change; Header tank is used to collect the moisture film that scrapes; Conduit is used for water is imported central tube and support set water tank; The central tube bearing is fixed on the drying cylinder end cap, is used for centre of support Guan Bingneng and central tube and produces relative rotation; Central tube links to each other with the drainpipe of swivel joint and is responsible for water is discharged drying cylinder.This device strikes off moisture film from the drying cylinder inwall, can in time remove condensed water, eliminate the condensed water water ring, improve the heat-transfer effect of casing wall, improve the utilization rate of steam, reduce steam consumption, and this device relies on gravity drainage, does not utilize pressure reduction, can increase substantially heat transfer efficiency, reduce steam consumption, reduce vapour losses.

Fig. 2 is the cross section structure schematic diagram of Fig. 1;
Fig. 3 is the structural representation of high speed paper machine drying cylinder condensate water extraction device of the present invention;
Fig. 4 is the cross section structure schematic diagram of Fig. 3.
The specific embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing:
Wherein: 1---swivel joint, 2---transmission side, 3---drainpipe, 4---header tank, 5---conduit, 6---bearing, 7---central tube, 8---fore side, 9---Wiper blade, 10---condensation film.
Embodiment: referring to Fig. 3 and Fig. 4, a kind of high speed paper machine drying cylinder condensate water extraction device, comprise drying cylinder, the transmission side 2 of described drying cylinder end cap is provided with swivel joint 1 and drainpipe 3, the inboard of described drying cylinder two ends end cap is respectively arranged with a bearing 6, a central tube 7 is installed between two bearings, be connected for rotary type between described central tube 7 and two bearings, the one end is connected and is communicated with the drainpipe 3 that runs through end cap, and its other end is a cecum, is arranged at intervals with row's conduit 5 on the axial tube wall of described central tube 7, the outer end of all conduits 5 all is connected and is communicated with header tank 4, conduit 5 has two effects, and the one, carry condensed water, the 2nd, the support fixation header tank; The outer end of described header tank 4 is provided with Wiper blade 9, and the outer end of this Wiper blade 9 contacts with described drying cylinder inner surface; The quantity of described conduit is more than two; Each conduit all is made up of two arms, the upper end of two arms is connected and is communicated with header tank 4 respectively, be connected and be communicated with described central tube 7 after its lower end crosses, perhaps, the lower end of two arms is connected and is communicated with central tube 7 respectively, and two tie points are positioned on the same radial section of described central tube 7; One is linear pattern in described two arms, and another is a broken line shape; The shape of cross section of described header tank 7 is the U type, and described Wiper blade 9 is made by the wear-resistant flexible material, and its lower side is fixed on the outer side edges of described header tank 4, its upper side edge and described drying cylinder inner surface Elastic Contact.
