る。The vacuum belt dryer has a constant-rate drying area, a decreasing-rate drying area, and a cooling area, which are sequentially arranged in the vacuum container, and a belt-conveying device for conveying the material to be dried to these areas. A material to be dried prepared in a liquid, slurry or paste form is dispersedly supplied onto the endless conveyor belt of the apparatus, and the material to be dried is rotated by the endless conveyor belt to obtain the constant rate drying area, the rate reduction area and the cooling area. It is configured to be vacuum-dried under relatively low temperature drying conditions. Due to this vacuum drying, the material to be dried supplied onto the endless conveyor belt undergoes a vigorous evaporation phenomenon of water contained therein, and the material to be dried expands and forms a large number of vent holes inside, As a porous intermediate product, it is sent to a crushing device provided at the end of the rotation path of the endless conveyor belt, and is taken out in a crushed state into granules.

欠陥を発生せしめる。By the way, the belt conveying device used as a conveying means for the material to be dried in the vacuum belt dryer moves at a constant speed from the material supplying station for the material to be dried to the drying station supplied on the endless conveying belt. Although configured to transfer heat energy for drying to the material, in practice the endless conveyor belt is often placed in an unstable drive condition due to meandering. Once such a phenomenon occurs, the conditions for supplying the material to be dried onto the endless conveyor belt become extremely unstable, and variations in the drying conditions cause defects in the final product, such as quality deterioration and component deterioration. Excuse me.

力の作用下で回動自在に支持させている。Therefore, in order to eliminate the adverse effect caused by the meandering of the endless conveyor belt, a belt conveyor device having a function of preventing the endless conveyor belt from meandering has been proposed. As shown in FIG. 4 and FIG. 5, this belt conveying device includes a drive roller (2) rotationally driven by a motor (1) and a hemispherical receiver (4) on a block (3). An endless conveyor belt (7) is wound between a driven roller (6) rotatably supported by a support frame (5) slidably mounted, and at both ends of the support frame (5). , A set of two air cylinder devices (8a) (8b) which are activated by a signal from a belt meandering detection sensor (not shown) are connected in series, and the endless conveyor belt (7) is driven by the drive roller (2). The roller (6) is rotatably supported under the action of a predetermined tensile force.

帰し、片寄りのない定常走行状態が再現される。When the meandering phenomenon does not occur in the endless conveyor belt (7), the feeding strokes of the piston rods of the two air cylinder devices (8a) and (8b) are equal, and the air cylinder devices (8a) and (8b) move from the support frame ( 5) and the tension force transmitted to the endless conveyor belt (7) via the driven roller (6) are equal. As a result, the endless conveyor belt (7) is supported by being wound around the center of the driven roller (6). On the other hand, when the meandering phenomenon occurs in the endless conveyor belt (7), the sensor sends a belt meandering detection signal, and the belt meandering detection signal is converted into an output signal by a control circuit (not shown) to be air cylinder device. (8a)
It is sent to (8b). For example, when the endless conveyor belt (7) meanders to the lower side in the drawing of FIG. 5, as shown in FIG. 6, the feeding stroke of the piston rod of the air cylinder device (8a) causes the other end of the other air cylinder device ( It becomes shorter than the payout stroke of the piston rod in 8b), which causes the driven roller (6) to tilt counterclockwise,
The endless conveyor belt (7), which is wound and supported on the driven roller (6), slides on the surface of the driven roller (6) due to the difference in pulling force at both edges, and as shown by arrow A, the meandering amount decreases. Move to. As a result, the steady winding support state shown in FIG. 5 in which the widthwise center of the endless conveyor belt (7) coincides with the widthwise center of the driven roller (6) is automatically reproduced. On the other hand, when the endless conveyor belt (7) meanders upward in FIG. 5, the air cylinder (8b)
By making the feeding stroke of the piston rod of No. 2 shorter than the feeding stroke of the piston rod of the other air cylinder device (8a), the posture control operation opposite to the above occurs, and the endless conveyor belt (7) is driven by the drive roller (7). 2) and the driven roller (6) are automatically returned to the center portion in the width direction, and a steady running state without deviation is reproduced.

張り力差が大きくなり、無端搬送ベルト(7)の強度劣
化が激しい。従って、無端搬送ベルト(7)の耐用期間
が著しく低減する。By the way, in the belt transport device, the endless transport belt (7) is prevented from meandering by inclining the driven roller (6) with the air cylinder devices (8a) and (8b). However, when the endless conveyor belt (7) is reversed by 180 ° on the driven roller (6) side, the endless conveyor belt (7) closely contacts the driven roller (6) by 180 ° and has a large contact area. ) And endless conveyor belt (7)
The frictional resistance with For this reason, when the driven roller (6) is inclined at a small inclination angle when the belt is prevented from meandering, the endless conveyor belt (7), as shown in FIG. Move to
In the latter half of the 90 ° reversal, the frictional resistance with the driven roller (6) is large, so it moves greatly in the direction opposite to the direction of decrease in meandering amount, and the decrease in meandering amount is small. Therefore, in order to move the endless conveyor belt (7) in the direction of decreasing the meandering amount and prevent the meandering, the driven roller (6) needs to be inclined at a large inclination angle. If the endless conveyor belt (7) is tilted at an angle, the difference in tensile force between both end edges of the endless conveyor belt (7) becomes large, and the strength of the endless conveyor belt (7) deteriorates significantly. Therefore, the service life of the endless conveyor belt (7) is significantly reduced.

のである。In order to solve the above-mentioned problems, the present invention winds an endless conveyor belt between a drive roller and a driven roller, and rotatably supports the driven roller on a tilting support frame. In a belt conveyor of a vacuum belt dryer configured to incline the driven roller in a direction in which the meandering amount is reduced by tilting the support frame when meandering, in the supporting frame, the traveling assist is provided in a position parallel to the driven roller. The rollers are rotatably or integrally supported, and the endless conveyor belt is composed of a lower end portion of the driven roller, a lower 1/4 circumferential surface of the traveling auxiliary roller and an upper 1/4 circumferential surface of the driven roller.
It is wound around the driven roller so that it sticks closely at the point.

動するようになった。When the endless conveyor belt is turned over 180 degrees on the driven roller side, the endless conveyor belt consists of the lower end of the driven roller, the lower 1/4 circumferential surface of the traveling auxiliary roller and the upper part 1 of the driven roller.
/ 4 The three sides of the circumference are closely contacted, and the 90 ° reversal of the first half is performed by the traveling auxiliary roller and the 90 ° reversal of the latter half is performed by the driven roller, which reduces the contact area between the endless conveyor belt and the driven roller. During that time, the frictional resistance was reduced, and when the belt was prevented from meandering, the amount of movement of the belt by the driven roller was suppressed to a small amount, and the endless conveyance belt moved greatly in the direction of decreasing the amount of meandering.
