Abstract
The utility model belongs to the technical field of paper machines, in particular to a drainage device for a paper machine drying cylinder, and mainly aims at breaking a water ring which blocks the heat supply for the drying cylinder and saving steam so as to reduce production energy consumption and provide the drainage device for the paper machine drying cylinder. The drainage device comprises the drying cylinder and a drainage pipe, wherein multiple water-collecting horizontal pipes in parallel with each other are uniformly distributed on the inner wall of the drying cylinder; the two ends of each water-collecting horizontal pipe are fixed on the inner wall of the drying cylinder through supports; water absorption holes with a diameter of 4 mm are uniformly formed in each water-collecting horizontal pipe; helix type vertical pipes are further arranged at the inner part of the drying cylinder; the two ends of each vertical pipe are communicated with the water-collecting horizontal pipes and the drainage pipe respectively through flanges. According to the drainage device, the water ring formed by condensate water in the drying cylinder is broken effectively, and large quantity of steam is saved, so that the mechanical production efficiency is improved, the production energy consumption is reduced, and the production cost of an enterprise is reduced.
Description
Technical field
The utility model belongs to paper machine technology field, relates to specifically a kind of paper machine dryer drainage arrangement.
Background technology
In the process of paper machine running, after its inner steam heat release, condense into condensed water, in the time that drying cylinder rotating speed is lower, condensed water will be gathered in drying cylinder bottom, in the time that drying cylinder rotating speed is higher, condensed water forms one deck water ring on drying cylinder inwall, has hindered the heat supply of drying cylinder; In solution in the past, there is the mode that is provided with U-shaped header tank on paper machine dryer inwall, break water ring, but adopt in this way, although water ring is broken, but also inevitably waste the ability of a large amount of water vapours, thereby energy consumption consumption is increased, increased the production cost of enterprise.
Summary of the invention
Goal of the invention of the present utility model:
Be mainly in order to solve paper machine dryer in running, the water ring that hinders drying cylinder heat supply can either be broken, condensed water can be discharged smoothly again, steam saving, thus reduce energy consumption.
The technical solution of the utility model is:
A kind of paper machine dryer drainage arrangement is provided, comprise drying cylinder and drainpipe, dispersedly on drying cylinder inwall be provided with multiple transverse tubes that catchment that are parallel to each other, the catchment two ends of transverse tube fix by bearing and drying cylinder inwall, uniformly on transverse tube be provided with the suction hole that diameter is 4mm catchmenting, also be provided with the standpipe of spiral form in the inside of drying cylinder, the two ends of standpipe are connected with catchment transverse tube and drainpipe respectively by flange, be 20mm in the distance of catchmenting between every two suction holes of offering on transverse tube, each transverse tube that catchments is at least fixed by two triangular supports.
The utility model beneficial effect is:
Can either effectively the water ring forming in drying cylinder operation process in paper machine be broken, improve the capacity of heat transmission of drying cylinder, again can be for manufacturing enterprise saves a large amount of steam, thus reduce production costs and energy consumption.

Fig. 1 is the structural representation that analyse and observe in front of the present utility model;
Fig. 2 is the structural representation that analyse and observe side of the present utility model;
Fig. 3 is the structural representation of transverse tube of originally catchmenting.
In figure, 1 is the transverse tube that catchments; 2 is flange; 3 is bearing; 4 is drainpipe; 5 is drying cylinder; 6 is triangular supports; 7 is standpipe; 8 is suction hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
As shown in Figures 1 to 3, a kind of paper machine dryer drainage arrangement is provided, comprise drying cylinder 5 and drainpipe 4, dispersedly on drying cylinder 5 inwalls be provided with multiple transverse tubes 1 that catchment that are parallel to each other, the catchment two ends of transverse tube 1 fix by bearing 3 and drying cylinder inwall, uniformly on transverse tube 1 be provided with the suction hole 8 that diameter is 4mm catchmenting, on transverse tube, offer suction hole catchmenting, mainly in order to reduce scattering and disappearing of steam in drying cylinder, thereby reduction energy consumption, , also be provided with the standpipe of spiral form in the inside of drying cylinder, it is mainly to consider that drying cylinder is in rotary course that standpipe is set to spiral line type, the conditional curve of current warp, if linear pattern of being set to, condensed water also can be adsorbed on the inwall of standpipe because of inertia, and be unfavorable for the discharge of condensed water, the two ends of standpipe are connected with catchment transverse tube and drainpipe respectively by flange, be 20mm in the distance of catchmenting between every two suction holes of offering on transverse tube, in order to keep the catchment stability of transverse tube and the stationarity of running, each transverse tube that catchments is at least fixed by two triangular supports.
Claims (3)
1. a paper machine dryer drainage arrangement, comprise drying cylinder and drainpipe, it is characterized in that: dispersedly on drying cylinder inwall be provided with multiple transverse tubes that catchment that are parallel to each other, the catchment two ends of transverse tube fix by bearing and drying cylinder inwall, uniformly on transverse tube be provided with the suction hole that diameter is 4mm catchmenting, also be provided with the standpipe of spiral form in the inside of drying cylinder, the two ends of standpipe are connected with catchment transverse tube and drainpipe respectively by flange.
