The drying device of the paper machine solves the problems that occupied space of a drying cylinder of a paper machine in the prior art is large, and when manufacture area is limited, the drying cylinder is hard to install and drying equipment with overlarge size is troublesome to operate. The drying device comprises a main control drying cylinder set (1), a secondary drying cylinder (2) and a water containing tank (5), wherein the secondary drying cylinder (2) is connected with the main control drying cylinder set (1) through a main control gas-water separator (3), and the water containing tank (5) is connected with the secondary drying cylinder (2) through a secondary gas-water separator (4). The drying device of the paper machine is characterized in that the main control drying cylinder set (1) is composed of two main control drying cylinders which are mutually connected, a condenser pump (6) which is arranged on the bottom of the water containing tank (5) in a communicated mode, three condenser pumps (6) are arranged between the main control gas-water separator (3) and the secondary gas-water separator (4) and are communicated with the main control gas-water separator (3) and the secondary gas-water separator (4) through pipelines, and the condenser pumps (6) are all communicated with the water containing tank (5) through guide pipes.
Description
Technical field
The utility model relates to a kind of drying equipment, specifically, is a kind of drying device of paper machine.
Background technology
Paper machine mainly is made of sections such as net, pressing and dryings.Two kinds of mesh portions cylinder and fourdrinier wires; Press section then is comprised of pressure roller and papermaker's felt etc.; Drying section then is comprised of one or several drying cylinder, and this part also is vital part in the paper industry link, and along with the development of technology, drying section of paper machine equipment has also obtained complete upgrading and adjustment.At present, the normal drying equipment that adopts all is to cooperate drying by multi-cylinder on the market, and it is dry thoroughly, efficient is high; But the multilevel drying cylinder takes up room greatly, when production site is limited, be difficult to install, and the excessive drying equipment of volume, operation is trouble very; On the other hand, because dry cylinder is the semi-hermetic type environment, it is in dry run, and steam is difficult to condense fully and is retained in the pipeline of drying equipment, has a strong impact on drying efficiency, to such an extent as to affect the quality of paper.
The utility model content
The purpose of this utility model is to overcome that the dry cylinder of paper machine takes up room greatly in the prior art, when production site is limited, be difficult to install, and the excessive drying equipment of volume, operation is the defective of trouble very, provide a kind of simple in structure, realize the easily drying device of paper machine.
To achieve these goals, the scheme of the utility model employing is as follows:
The drying device of paper machine, comprise master control oven dry cylinder group, dry the secondary oven dry cylinder that the cylinder group is connected by the master control moisture trap with master control, the jug that is connected by the secondary oven dry cylinder of secondary moisture trap and this, described master control oven dry cylinder group is made of two interconnective master control oven dry cylinders, and also be provided with the condensate pump that is communicated with it in the bottom of jug, and between master control moisture trap and secondary moisture trap, be provided with three condensate pumps that are communicated with it by pipeline, and described condensate pump is communicated with jug by conduit all.
Further, on described secondary moisture trap, also be provided with a conduit that is communicated with it, and the external vavuum pump of an end of this conduit.
Further, described jug is uncovered shape.
Further, described master control oven dry cylinder is in parallel by pipeline.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is not only simple in structure, and with low cost, realization convenience;
(2) master control oven dry cylinder group is made of two equal master control oven dry cylinders in the utility model, it is reduced to the two-stage oven dry with traditional multistage oven dry, when guaranteeing drying effect, has reduced widely the shared area of oven dry cylinder, not only simplify operation, and reduced production cost;
(3) the utility model also is provided with a jug that is connected with secondary oven dry cylinder by secondary moisture trap, jug is in order to receive condensed steam, by the condensate pump that is arranged on its bottom it is cooled off again, steam after being cooled can be recycled again, saving water resource;
(4) the utility model and be provided with three condensate pumps that are communicated with it by pipeline between master control moisture trap and the secondary moisture trap, and described condensate pump all is communicated with jug by conduit.Condensate pump can be cooled to rapidly liquid state with steam, again in the jug by the pipeline inflow, has effectively avoided being difficult to steam and has been difficult to condense and is retained in the pipeline of drying equipment, affects the defective of drying efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, the parts name that Reference numeral is corresponding is called: 1-master control oven dry cylinder group, 2-level oven dry cylinder, 3-master control moisture trap, 4-level moisture trap, 5-jug, 6-condensate pump, 7-valve.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment
As shown in Figure 1, the drying device of paper machine, comprise master control oven dry cylinder group 1, dry the secondary oven dry cylinder 2 that cylinder group 1 is connected by master control moisture trap 3 with master control, the jug 5 that is connected by the secondary oven dry cylinder 2 of secondary moisture trap 4 and this, described master control oven dry cylinder group 1 is made of two interconnective master control oven dry cylinders, and also be provided with the condensate pump 6 that is communicated with it in the bottom of jug 5, and between master control moisture trap 3 and secondary moisture trap 4, be provided with three condensate pumps 6 that are communicated with it by pipeline, and described condensate pump 6 is communicated with jug 5 by conduit all.Condensate pump can be cooled to rapidly liquid state with steam, again in the jug by the pipeline inflow, has effectively avoided being difficult to steam and has been difficult to condense and is retained in the pipeline of drying equipment, affects the defective of drying efficiency.
In the present embodiment, in order further to guarantee drying effect, on described secondary moisture trap 4, also be provided with a conduit that is communicated with it, and the external vavuum pump of an end of this conduit.Vavuum pump is used for detaching fixed gas, has effectively guaranteed the operating pressure in the oven dry cylinder.
In the present embodiment, between the oven dry cylinder, between oven dry cylinder and the moisture trap and is connected by pipeline between the moisture trap, and on pipeline, also be provided with valve 7 in order to the control switching; During work, steam enters in the equipment from the pipeline that is connected with master control oven dry cylinder group 1.
In the present embodiment, described jug 7 is uncovered shape, and also is provided with the condensate pump 6 that is communicated with it in described jug 7 bottoms.Jug is in order to receive condensed steam, and the condensate pump by being arranged on its bottom 6 cools off it again, and the steam after being cooled can be recycled again, saving water resource.
