"A dryer for drying wet hank yarn"

Abstract

A hank dryer is proposed for drying hank yarn or other products by exposure to hot air. The dryer primarily works on solar energy but has also the capability to function on conventional energy when solar energy is not available. It can also work partly with solar energy and partly with conventional energy when solar energy is not available in full intensity. The dryer has a set of solar flat plate collectors (1) with hot air pipe line (2) connected thereto, blower motor (11) to blow hot air thus collected, into the drying chamber (6) through series of nozzles (9) fixed on hot air pipe (14). A trolley (7) is provided within the drying chamber (6) which has means by which wet hank yarn to be dried can be hung. Hot air pipe (3), regulating valve (4), radiator (5) fitted with fan (13) are provided to receive hot air generated through the use of conventional energy and to blow into the drying chamber (6).

FIELD OF INVENTION This invention relates to a dryer for drying wet hank yarn or other products by exposure to hot air which works primarily based on solar energy and has also alternative arrangement to use conventional energy when solar energy is not available. PRIOR ART Due to rapidly depleting availability of fossil fuels like coal, petroleum fuels, efforts are being make world over to conserve conventional energy sources by using alternate sources of energy. Though use of solar energy is reported in the art for various applications, no device is reported for use for drying of textile yarn, particularly which can work both on solar energy as well as on conventional energy. OBJECTS OF PRESENT INVENTION The main object of the present invention is to propose a hank dryer which is designed to work both with solar energy as well as with conventional source of energy. DESCRIPTION OF FIGURES The invention will now be illustrated with an accompanying figure which is intended to illustrate an embodiment of the present invention and is not intended to be taken restrictively to imply any limitation on the scope of the present invention. It is to be noted that the principles and features of the present invention can be employed in variant embodiments by those skilled in art. Such variant embodiments are intended to be within the scope of the present invention. In the accompanying figure:- (c) blower-motor (11) which blows hot air received through pipeline (2) from solar flat plate collectors (1), into the drying chamber (6); (d) regulating valve (10) to regulate hot air inflow from solar plate collectors (1) to the drying chamber (6); (e) regualting valve (4) to regualte the inflow of hot air/steam into the radiator using conventional enegy through pipeline (3); (f) a series of hot air nozzles (9) fixed on hot air pipe (14) through which hot air under pressure is pressed into the drying chamber (6); (g) a trolley (7) with racks (15) for hanging wet hank yarn (8). DESCRIPTION OF FIGURES The invention will now be illustrated with an accompanying figure which is intended to illustrate an embodiment of the present invention and is not intended to be taken restrictively to imply any limtation on the scope of the present invention. It is to be noted that the principles and features of the present invention can be employed in variant embodiments by those skilled in art. Such variant embodiments are intended to be within the scope of the present invention, tn the accompanying figure: Fig. 1 shows the schematic layout of a dryer for drying wet hank yarn; PESCR1TP1ON OF INVENTION W.R.T DRAWINGS Referring to fig. 1, the hank dryer of the present invention comprises a set of solar flat plate collectors like the plate collector (1). Each flat plate collector (1) has opening (12) which connect each of the plat collector (1) to the insulated main hot air pipeline (2). Each flat plate collector (1) is designed to absorb solar heat and transfer it to the air which flows below through the annular space and the individual opening (12). At the other end of hot air pipeline (2), a blower-motor (11) is provided which blows the hot air into the drying chamber (6) which is prferably transparent so as to retain the heat of air. The flow of hot air from the system of flat plate collectors (1) is regulates by valve (10). The hot air which is blows inside the chamber (6) at a high pressure, is passed through series of nozzles (9) fixed on pipe (14). The wet hank yams (8) which are to be dried, are hung in a trolley (7) which has racks arrangement to hang the yarns. The hot air generated with conventional energy is led to the drying chamber (6) through pipe (3) which is provided with regulating valve (4). This valve (4) is opened when required to supply and regulate hot air generated by conventional source of energy to radiator (5) fitted with fan (13), whenever solar energy is not available. The valve (4) may also kept partially open to slow down the hot air through pipe (3) from conventional source of energy, when solar intensity is low, so that dryer works partly with solar energy and partly with conventional energy. So the hybrid hank system of the present invention is flexible in the sense that it can work either exclusively on solar energy when solar energy is available with full intensity or it can work exclusively with conventional energy or it can work simultaneously with solar energy as well as conventional energy using hot air partly generated with solar energy and partly with conventional energy, by regulating the valves (4) and (10). So the Dryer of the present inventionremains operational whether solar energy is available with full intensity or available in low intensity or when solar energy is not available, thereby avoids production losses. It is to be understood that the dryer of the present invention is susceptible to modifications, amendments, changes by those skilled in the art. Such variations in the construction of the dryer, are intended to be within the scope of the present invention, which is further set forth under the following claims:- WE CLAIM; 1 . A dryer for drying wet hank yarn comprising: (a) solar flat plate collectors (1) provided with openings (12) which connect each of said solar flat plate collector (1) to the hot air pipeline(2); (b) a drying chamber (6) provided with a radiator (5) fitted with a fan (13); (c) blower-motor (11) which blows hot air received through pipeline (2) from solar flat plate collectors (1), into the drying chamber (6); (d) regulating valve (10) to regulate hot air inflow from solar plate collectors (1) to the drying chamber (6); (e) regulating valve (4) to regulate the inflow of hot air/ steam into the radiator using conventional energy through pipeline (3); (f) a series of hot air nozzles (9) fixed on hot air pipe (14) through which hot air under pressure is pressed into the drying chamber (6); (g) a trolley (7) with racks (15) for hanging wet hank yarn (8). 2. A dryer for drying wet hank yarn as herein substantially described and illustrated in accompanying drawing.
