DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a drying device for continuously drying a long fabric with hot air.

(Prior Art) As a fabric drying device, a large number of guide rollers are vertically arranged at the front and rear of a box-shaped drying chamber, and hot air is blown between the guide rollers in the front row and the guide rollers in the rear row. It is known that a main duct for circulation is erected, and blowing ducts for blowing hot air in the vertical direction are branched in the width direction and in multiple stages at opposing portions of the left and right main ducts. As an example of such a type of drying device, Japanese Utility Model Laid-Open No. Sho 59-195494 discloses that the above-mentioned main ducts are provided with a blower fan for circulating hot air at each upper end of the left and right main ducts. , A plurality of box-shaped ducts adjacent to each other in the vertical direction and independent of each other are formed, and a ventilation fan is attached to each of these box-shaped ducts.

(Problems to be solved by the invention) In the case where the blower fan and its drive motor are attached to the upper end of the main duct, the blower fan and the drive motor must be raised above the drying chamber when the drying device is assembled. Since it does not occur, there is a problem that there is a lot of work at a high place and it is dangerous, and a work at a high place is required for maintenance work such as bearing replacement and cleaning.

In addition, since a plurality of box-shaped ducts are arranged vertically, the above-mentioned blower fan and drive motor are mounted on the outside of these box-shaped ducts, so the overall width of the dryer is wide and the installation area is wide. In addition, the installation position of the blower fan or the like is higher than the floor surface for the box-shaped duct having the second or more stages from the bottom, which requires work at a high place.

This invention provides a fabric drying device that does not require widening of the entire drying device and does not require work at a high place for mounting the blower fan and its drive motor.

(Means for solving the problem) A large number of guide rollers are arranged in the vertical direction at the front and rear of the box-shaped drying chamber, and hot air circulates between the guide rollers in the front row and the guide rollers in the rear row. The main duct for the erection is provided upright, and the branch ducts for blowing hot air in the vertical direction are provided in the opposing portions of the left and right main ducts in the width direction and in a multi-stage manner in the drying device, under the drying chamber. A fan chamber is provided adjacent to the fan chamber, and blower fans for circulating hot air are provided at the front and rear of the fan chamber so that their outlets face each other, and the lower ends of the left and right main ducts serve as suction ports. Is provided on the left and right of the upper part, and a rectifying plate is provided in the middle of the front and rear air blowers for guiding the hot air in the front-rear direction outward in the width direction and guiding it to the suction port of the main duct.

(Function) The fabric introduced into the upper part of the drying chamber is guided by the guide rollers of the air as in the conventional case, and is guided back and forth while being guided from the top to the bottom, while the hot air blown out from the branch duct is moved up and down. It is dried on both sides and then discharged from the bottom of the drying chamber.

On the other hand, the hot air blown from the branch duct, after colliding with the cloth in the front-rear direction, flows forward and backward along both the upper and lower surfaces of the cloth, further descends along the front and rear walls, and enters the front and rear of the fan chamber, The air is blown from the front and rear fans toward the center, and the direction is changed outward in the width direction by the current plate, and the air is circulated to the main duct. The hot air is reheated according to a conventional method until it collides with the cloth and enters the fan chamber.

(Example) In FIG. 1, a box-shaped chamber 1 is made of a heat insulating material,
It is vertically divided by a horizontal partition plate 2 located in the lower part in the height direction, and the upper side thereof is formed in the drying chamber 3 and the lower side thereof is formed in the fan chamber 4. The horizontal partition plate 2 is
Made to cross the widthwise center in the front-back direction (3rd
(See the drawing), the drying chamber 3 and the fan chamber 4 communicate with each other on the side of the horizontal partition plate 2.

The above-mentioned drying chamber 3 is provided with the front, rear, left and right vertical partition plates 5 (see FIG. 3) protruding upward from the front and rear portions of the left and right side edges of the horizontal partition plate 2 so that the left, the center, and the right are separated. It is divided into three chambers, and a large number of guide rollers 6 (see FIG. 1) are vertically arranged at the front and the rear of the central chamber, respectively, and introduced from an inlet 1a opening at the upper front of the chamber 1. The fabric F is guided back and forth while reciprocating back and forth, and is discharged from the outlet 1b that opens at a position near the lower rear surface of the chamber 1. Then, the left and right chambers have front and rear vertical partition walls 5, 5 respectively.
A main duct 7 for circulating hot air is provided so as to span, and branch ducts 8 for blowing hot air up and down to the left and right main ducts 7, 7 are branched in the width direction and in multiple stages. In FIG. 3, reference numeral 8a is an outlet provided in the branch duct 8. Further, heaters 9 which are long in the vertical direction are attached to the vertical partition walls 5 on the front, rear, left and right, and the hot air in the central chamber is heated by the heaters 9.
It passes through and goes out to the left and right chambers, and is heated at that time. As is apparent from FIG. 2, the main duct 7 is formed in a triangular shape whose width becomes narrower from bottom to top, the upper end is closed, and the lower end is opened toward the fan chamber 4. There is.

The fan chamber 4 is divided into three chambers, front, center and rear, by front and rear partition plates 10 parallel to the front and rear wall surfaces of the chamber 1 (see FIG. 3). A blower fan 11 for circulating hot air, a motor casing 12, and a drive motor 13 are provided at each center so that the outlet 11a of the blower fan 11 faces the central chamber. And in the center of the central chamber (3rd
(Refer to the drawing) Straightening vanes 14 and 15 are provided for changing the hot air in the front-rear direction outward in the width direction.

In the above structure, the hot air blown toward the center from the front and rear blower fans 11 changes the direction to the width direction outward by the straightening vanes 14 and 15 and reaches the bottom of the main duct 7, and then the main duct 7 It rises up inside and is jetted from the branch duct 8 into the drying chamber 3 and collides with the fabric F, then changes direction and is divided into two parts, that is, the front part and the rear part of the drying chamber 3. And is reheated and introduced into the lower fan chamber 4 and is circulated again by the blower fan 11.

In the above-mentioned embodiment, one blowing fan 11 is provided at each of the front part and the rear part of the fan chamber 4, but two or three blowing fans 11 may be provided side by side in the width direction.

(Effects of the Invention) The invention is to provide a fan chamber adjacent below the drying chamber, to provide ventilation fans in front of and behind the fan chamber, and to use the lower ends of the left and right main ducts as suction ports for the fan chamber. The upper part of the air duct is opened to the left and right, and a straightening vane is provided in the middle of the front and rear air blowers to change the hot air in the front-back direction outward in the width direction and guide it to the suction port of the main duct. The hot air that has been supplied and reheated is sent out in a front-to-back opposed manner by the front and rear blowing fans in the fan chamber, and then the flow direction is changed outward in the width direction by the middle straightening plate. Therefore, the hot air is smoothly guided to the suction port at the lower end of the main duct without causing turbulence and is circulated in the main duct. Further, since the fan chamber is provided adjacent to the lower part of the drying chamber, the front wall and the rear wall of the drying chamber can be extended downward and the ventilation fan can be provided inside the extended portion, so that the installation area can be reduced. Does not increase. And, since the blower fan and the drive motor are installed at the bottom of the chamber, it is not necessary to work at a high place for mounting, replacing parts, cleaning, etc.
