Description

[Detailed Description of the Invention] The present invention relates to a drying device that dries the tile material by sending hot air into a drying path while transporting a drying cart loaded with tile material in a drying oven.

Conventional tile drying equipment transports a drying cart loaded with tile blanks in one direction in a drying oven, blows hot air into the spaces on both sides of the transport path, and blows hot air along the transport direction on both sides of the transport path. A pair of moving frames are provided which repeat reciprocating motion at the same time.Blowing fans and suction fans are placed on both moving frames at alternating intervals and facing each other, so that the hot air crosses the conveyance path at right angles. There is a known drying device that can dry the tile base evenly by moving the hot air across the conveyor path in the conveying direction, but in the case of conventional devices, both moving frames Because the space between the blowout fan and the suction fan was open, some of the hot air blown by the blowout fan hit the tile base and escaped to the outside through the open opening, creating negative pressure in the blowout. This creates a swirling flow that appears to flow on the back side of the fan, and a portion of the hot air sucked out by the suction fan also flows through the open opening to the back side of the suction fan, where negative pressure is created. This resulted in a reduction in the amount of hot air involved in drying the tile base, resulting in poor drying efficiency.

The object of the present invention is to provide a drying device that can eliminate the above-mentioned problems and efficiently apply hot air to the tile base.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

Two pairs of rails 3, 3 are laid on the top surface of the base 2, which is fixed across the entire length of the tunnel-shaped drying oven 1 in the center of the width direction.
A large number of columns 4 are erected at regular intervals on both sides of the column, and a top plate 5 is spanned and rotated between the upper ends of the columns 4 on both sides, and a conveyance path 6 is formed therein. , multi-tiered drying rack 9 for loading tile material
A large number of drying carts 8 having a partition plate 10 attached to the front surface are successively placed on the rails 3, 3 in two rows, and the drying carts 8 are inserted into the drying furnace 1 from the entrance side. By sequentially pushing them in, they are conveyed along the conveyance path 6 in the direction of arrow A in FIG.

On both sides of the conveyance path 6, a pair of left and right moving frames 12, 12, which are elongated in the conveyance direction A, are provided with an upper guide rail 15, which has a roller 13 pivotally supported on the upper edge of each frame, and is fixed to the outer surface of the support column 4. Also, by sandwiching the lower guide rail 16 between a pair of rollers 14, 14 pivotally supported on the lower edge, both guide rails 15, 1
A plurality of pairs of shafts 18 are attached so as to be movable along the conveyance path 6, and a shaft 18 is supported on the upper surface of the conveyance path 6 across the conveyance path 6, corresponding to each pair of moving frames 12, 12. A chain 22 is stretched between a sprocket 19 fixed to the shaft 18 and a sprocket 21 fixed to the output shaft of the motor 20, and a sprocket 24 fixed to both ends of the shaft 18.
and a sprocket 28 fixed to a shaft 27 supported by a bracket 26, and a sprocket 30 fixed on the same shaft 27 inside the sprocket 28.
An endless chain 33 is stretched between sprockets 32 that are pivotally supported by a bracket 31 that is attached to the rear of the bracket 26 in the transport direction A, and each moving frame 1 is connected to a straight running section below the sprocket 32.
A connecting member 35 fixed to the upper edges of 2 and 12 is connected, and the pair of moving frames 12 and 12 are moved along the conveying direction A by driving the motor 20 forward or backward for a certain period of time. It is designed to simultaneously repeat reciprocating movements over a fixed distance.

The movable frames 12, 12 are partitioned into a plurality of sections in the length direction by a vertical frame 37, and two blow-off fans 38 and two suction fans 39, each consisting of two upper and lower sections, are arranged alternately between the three sections. , and one of the blowing fans 3 of both moving frames 12
8 is arranged to face the other suction fan 39, and a closing plate 40 is stretched between the blow-off fan 38 and the suction fan 39 of both movable frames 12.

Further, at the bottom of the space on both sides of the conveyance path 6 in the drying oven 1, a hot air supply duct 42 having discharge ports 43 formed at regular intervals on the upper surface is arranged.

Next, the operation of this embodiment will be explained. At the same time as the drying cart 8 is transported in the direction of the arrow A in FIG. , balloon fan 38
The hot air blown into the conveying path 6 is sucked in by the opposing suction fan 39, so that the hot air flows across the conveying path 6, and the blowing fans 38 and suction fans 39 are arranged alternately. The hot air flows alternately in opposite directions perpendicular to the transport direction A and is applied to the tile base, and the movable frames 12, 12 equipped with both fans 38, 39 repeat reciprocating motions, causing hot air to flow across the transport path 6. Since it moves along the conveying direction A, hot air is applied to the tile base continuously and evenly, not intermittently, and furthermore, each of the fans 38 and 39 of the moving frame 12
Since the closing plate 40 is stretched between the sections,
The hot air blown by the blowing fan 38 hits the tile base and is prevented from escaping to the outside of the conveyance path 6.
Furthermore, since the hot air sucked in by the suction fan 39 is prevented from entering the conveyance path 6 again, it is possible to ensure a sufficient amount of hot air involved in drying the tile base.

Further, in this embodiment, since the partition plate 10 is attached to the cart 8, the hot air can smoothly flow between the partition plates 10 of the adjacent carts 8 without being dispersed.
It is possible to dry the tile base more efficiently.

As specifically explained in the above embodiment,
The tile drying apparatus of the present invention includes a hot air supply duct having discharge ports formed at appropriate intervals in a space on both sides of a conveyance path through which a drying cart loaded with tile blanks passes in a drying oven. A pair of elongated moving frames in the conveying direction are provided on both sides of the conveying path, and a pair of moving frames that are elongated in the conveying direction are provided that simultaneously repeat reciprocating motions over a certain distance along the conveying direction of the drying cart, and a plurality of blowing fans and suction fans are installed on both moving frames. at alternating intervals, and
The apparatus is arranged so as to face each other, and the space between the respective fans of both the moving frames is closed with a closing plate, and when hot air is discharged from the outlet of the hot air supply duct, The hot air is blown out by the blowout fan, and because of the blocking plate, it does not escape to the outside of the conveyance path, but instead is drawn in across the conveyance path at right angles to the opposite suction fan.The hot air sucked in by the suction fan is , because there is also a blocking plate, the air passes through between the blocking plate and the furnace wall, without returning to the conveyance path, to the adjacent blow-off fan, and from that blow-off fan to the suction fan facing it, in the opposite direction to the above. A circular flow is created in which the flow is blown across the conveying path at right angles, passes between the blocking plate on the opposite side and the furnace wall, and is blown in again from the first blowing fan. As the tile material reciprocates along the conveyance path, the flow of hot air in opposite directions across the drying cart reciprocates along the conveyance direction, drying the tile base. Since it can be applied evenly over the tile base, it has the effect of drying the tile base evenly and evenly.
