W. S. BOWEN OPEN STEAM Box DRIER oct. 1o, 1944.
2 sheets-sheet? Filed Nov. 24, 1941 flu/en for fa/4M .Spf/raf# aon/m' Patented Oct. 10, 1944 UNITED j STATES ATENT OFFICE OPEN STEAM BOX DRIER William Spencer Bowen, Westfield, N. J. Application November 24, 1941, Serial No. 420,181 y 4 claims.l (o1. :s4-22a) The `present invention relates to drying mechanisms and embodies, ymore specically, a drier by means of which continuous drying of material may be accomplished in a highly eilective manner.
,Belt drying mechanisms have long been inuse, such mechanisms including a chamber arrangement by means of Which a drying medium may be circulated about the material on the belt in order to accomplish its drying. The present invention utilizes these broad and general features of belt drying mechanisms and incorporates therewith further structure bymeans of which drying may be accomplished effectively and at Very low cost. l
An object of the invention, accordingly, is to provide an improved belt drying mechanism which is simple and relatively inexpensive in construction and highly efcient in operation in order that desired drying operations may be accomplished.
A further object of the invention is to provide a drier of the above character wherein the heat of condensation of a medium may be utilized to eiect the drying operation.
Further objects of the invention will be apparent from a description of the manner in which these objects are attained, which, generally speaking, consists in the provision of a steam box so related to a movable heat transmitting belt that the heat of condensation is utilized as an effective drying means. This structure is assembled in such fashion that the belt passes over and forms generally the top of the open steam box, the entire mechanism being included within a chamber in which air or gas currents may be circulated. A
The foregoing objects and structure will be understood more fully from a detailed description of the invention which, for present purposes, is shown as embodied in the structure illustrated in the accompanying drawings, wherein Figure l is a View in vertical section, taken longitudinally of a drying mechanism constructed in accordance with the present invention, and
Figure 2 is a View in cross-section taken on line 2 2 of Figure 1.
Referring to the above drawings, a housing is shown at i to provide a drying chamber 2 Within which an endless belt 3 is mounted. The belt is supported over pulleys 4 and 5, pulley 5 being driven by a belt 6 from a variable speed gear mechanism 'I that is driven by a motor 8. The details of the foregoing mechanism are comparatively unimportant except that the belt 3 ispreferably formed of metal'such as aluminum or stainless steel in order that it may be a `good heat conductor;A SideV guides 9 are provided, if desired, and a feed hopper I0 is formed in the top Wall of the housing I in order to'feed the ma'- terial to be dried onto the belt at Vone end thereof.
Beneath the upper span of the belt 3 a steam box I I is mounted, the box being open at its top I2. Rubber gaskets I3 or other sealing means may be provided about the periphery of the top of the box in order that the moving belt 3 may form Va reasonably good closure for the box. Steam is introduced` into the box II through a pipe I4 and the condensate is discharged therefrom through an outlet pipe I5.
An inlet pipe I6 is provided to introduce drying air into the chamber 2, the air being discharged from the opposite end through outlet pipe I"I.
A rotary brush I8 and scraper I9 are provided to remove the dried material on the belt 3 at the end of the drying cycle of the operation. A discharge hopper 20 is provided to receive. the dried material removed from the belt.
In operation, it will be observed that the heat of condensation of the steam in the open steam box II will function as an effective drying agent to dry the material that has been applied to the top span of the belt 3 by the feed hopper I0. The material will dry in a flat condition on the belt and then, as the belt moves about the pulley 5, the material will co-act so that it will be capable of being removed easily by the brush I8 and scraper I9. The construction is such that a counter current of drying air may be utilized not only to aid in drying but also to remove the moisture in the chamber 2, resulting from the drying. It will be apparent that, with the structure above referred to, dry air will be in contact with dry material, while the more moist air will be in contact with the moister material, the tem- .perature of the air decreasing as it progresses through the chamber 2.
While the invention has been described with reference to the specic structure shown in the accompanying drawings, it is not to be limited save as dened in the appended claims.
I claim:
