Abstract
The invention discloses a windless dryer, solving the problems that a drying cylinder of a papermaking machine occupies a large space and is difficult to install when a production field is limited, and operation is also very complicated due to overlarge volume of drying equipment in the prior art. The drying equipment comprises a main control drying cylinder group (1), a secondary drying cylinder (2) connected with the main control drying cylinder group (1) through a main control gas-water separator (3) and a water containing tank (5) connected with the secondary drying cylinder (2) through a secondary gas-water separator (4), and is characterized in that the main control drying cylinder group (1) consists of two main control drying cylinders which are mutually connected, a condensate pump (6) which is communicated with the water containing tank (5) is also arranged at the bottom of the water containing tank (5), three condensate pumps (6) which are communicated with the main control gas-water separator (3) and the secondary gas-water separator (4) are also arranged between the main control gas-water separator (3) and the secondary gas-water separator (4), and the condensate pumps (6) are all communicated with the water containing tank (5) through catheters.
Description
Technical field
What the present invention relates to is a kind of drying equipment, specifically, is a kind of calm drying machine.
Background technology
Paper machine mainly is made up of portions such as net, squeezing and dryings.Two kinds of mesh portions cylinder and fourdrinier wires; Press section then is made up of pressure roller and papermaker's felt etc.; Drying section then is made up of one or several drying cylinder, and this part also is a 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 influence the quality of paper.
Summary of the invention
The objective of the invention 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, and a kind of simple in structure, calm easily drying machine of realization is provided.
To achieve these goals, the scheme of the present invention's employing is following:
Calm drying machine; Comprise master control oven dry cylinder group, dry the secondary oven dry cylinder that the cylinder group is connected with master control, the jug that is connected through the secondary oven dry cylinder of secondary moisture trap and this through the master control moisture trap; Said master control oven dry cylinder group is made up 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 through pipeline, and said condensate pump all is communicated with jug through conduit; And in master control oven dry cylinder, secondary oven dry cylinder, be equipped with temperature sensor, this temperature sensor is connected with outside central controlling chamber.
Further, on said 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 again, said jug is uncovered shape.
Further, said master control oven dry cylinder is in parallel through pipeline.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention is not only simple in structure, and with low cost, realization convenience;
(2) master control oven dry cylinder group is made up of two equal master control oven dry cylinders among the present invention; It is reduced to the two-stage oven dry with traditional multistage oven dry, when guaranteeing drying effect, has reduced the shared area of oven dry cylinder widely; Not only simplify operation, and reduced production cost;
(3) the present invention also is provided with a jug that is connected with secondary oven dry cylinder through secondary moisture trap; Jug is in order to receive condensed steam; Through the condensate pump that is arranged on its bottom it is cooled off again; Steam after being cooled can be recycled once more, the conserve water resource;
(4) the present invention and be provided with three condensate pumps that are communicated with it through pipeline between master control moisture trap and the secondary moisture trap, and said condensate pump all is communicated with jug through conduit.Condensate pump can be cooled to liquid state rapidly with steam, again in the jug by the pipeline inflow, has avoided being difficult to steam effectively and has been difficult to condense and is retained in the pipeline of drying equipment, influences the defective of drying efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention.
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, 8-temperature sensor.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing thereof the present invention is done to specify further, but embodiment of the present invention is not limited thereto.
Embodiment
As shown in Figure 1; Calm drying machine; Comprise master control oven dry cylinder group 1, dry the secondary oven dry cylinder 2 that cylinder group 1 is connected with master control, the jug 5 that is connected through the secondary oven dry cylinder 2 of secondary moisture trap 4 and this through master control moisture trap 3; Said master control oven dry cylinder group 1 is made up 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 through pipeline, and said condensate pump 6 all is communicated with jug 5 through conduit.Condensate pump can be cooled to liquid state rapidly with steam, again in the jug by the pipeline inflow, has avoided being difficult to steam effectively and has been difficult to condense and is retained in the pipeline of drying equipment, influences the defective of drying efficiency.
In the present embodiment; In master control oven dry cylinder, secondary oven dry cylinder 2, be equipped with temperature sensor 8; This temperature sensor 8 is connected with outside central controlling chamber; The staff can be instant the temperature in the oven dry cylinder monitor, avoided in the oven dry cylinder the too high oven dry that causes of temperature excessively or dry halfway defective effectively.
In the present embodiment,, on said secondary moisture trap 4, also be provided with a conduit that is communicated with it in order further to guarantee drying effect, and the external vavuum pump of an end of this conduit.Vavuum pump is used to detach fixed gas, has guaranteed the operating pressure in the oven dry cylinder effectively.
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, said jug 7 is uncovered shape, and also is provided with the condensate pump 6 that is communicated with it in said jug 7 bottoms.Jug is in order to receive condensed steam, and the condensate pump through being arranged on its bottom 6 cools off it again, and the steam after being cooled can be recycled once more, the conserve water resource.
According to the foregoing description, can well realize the present invention.
