Definitions

• the present invention relates to a drier for drying fire-hoses or other similar hoses. More particularly, the invention relates to such a drier, comprising an elongated horizontal receptacle in which a plurality of wet hoses may be placed side by side in extended positions to undergo drying in said receptacle upon closure of the space in which the hoses have been placed.
• a drier of said kind usually forms part of a complete hose cleaning plant, also including a washing equipment, located at one end of said receptacle.
• Hoses to be cleaned are drawn slowly one by one through said washing equipment and are then laid down in the receptacle of the drier through a longitudinal opening, provided at the upper end of said receptacle, when a drying process is to be initiated, said opening is closed by means of a suitable cover.
• the washing operation successively performed on the hoses as well as the step of laying down the hoses in the receptacle takes considerable time. Additional time is spent on testing the hoses, before the drying process can be started.
• An object of the invention is to provide an improved drier of the kind initially specified, which facilitates an almost continuous operation of the drier itself as well as of a complete hose cleaning plant wherein the drier is included.
• a drier of said kind which is primarily characterized in that the receptacle is divided into two parallell drying chambers, extending in side by side relationship along the length of the receptacle and having individually closable longitudinal openings at their upper ends .
• drying operations to be effected in the drying chambers may suitably be obtained by blowing hot air through the hoses as well as around them within said chambers.
• the necessary equipment for generating hot air and for providing moistur separation, etcetera may suitably be common to both drying chambers.
• the drier may be provided with a single cover which is common to both drying chambers and adapted to close only one of said chambers at a time.
• the drier may be provided with two covers, one for each drying chambers, in which case the two covers may be connected to each other so as to permit only one drying chamber at a time to be closed by its cover.
• Such an inter connection between the two covers will make it possible to operate them by means of a common driving element and eliminates the need for separate driving elements for the two covers.
• the two covers may be mounted on a common carrier and be arranged to act as counterweights for each other. Such an arrangement will result in a reduction of the required driving power for the driving member of the two covers. Both covers may suitably be rigidly mounted on a common rotatable shaft, located between them.
• the covers may extend in such directions from said shaft as to form an angle exceeding 90 between their upper surfaces. Said angle may preferably amount to about 120 .
• the maximum resultant torque on said shaft, caused by the two covers, will then amount to a value corresponding to half the value of the maximum torque on the shaft, caused by one of said covers.
• the drier shown in the drawing, comprises an elongated box-like body of sheet metal, generally designated 10. At its upper end, the drier is provided with two parallell drying chambers 11 which extend in the longitudinal direction of body 10 and are slightly spaced apart in the transversal direction of body 10. Said two drying chambers 11 are formed by elongated tubs 12 having heat-insulated side walls and bottom walls. The longitudinal openings provided at the upper ends of drying chambers 11 are individually closable, each by means of an appurtenant cover 13. These two covers 13 are carried by a common shaft 14, located- between the two covers and extending in the longitudinal direction of body 10. The two covers 13 are rigidly mounted on shaft 14 by means of a number of supporting arms 15 evenly distributed along the length of shaft 14.
• Reference numeral 16 designates a driving motor for shaft 14, mounted on body 10.
• the driving motor 16 which suitably may consist of a hydraulic motor, has been shown to be connected to shaft 14 by means of a chain transmission 17.
• a grid-like supporting member 18 is provided on some distance above the bottom of the chamber and extending along the whole length of the chamber.
• hoses 19 may be placed side by side in extended positions to undergo a drying operation upon closure of chamber 11 by means of its appurtenant cover 13.
• the drying operation may suitably be effected by blowing hot air through hoses 19 as well as around said hoses within drying chamber 11.
• said air may suitably be caused to circulate within a closed system, comprising necessary means for separating moisture from the air when leaving the drying chamber. Since the two drying chambers 11 are intended to operate in an alternating manner, said system, which may be common to both drying chambers, need not have a larger capacity than required for one of said chambers.
