Description

[Detailed explanation of the invention] (Purpose of the invention) The invention is based on the invention: the clay tile molded material, which is automatically molded and transported on a pallet, is loaded onto a drying trolley and circulated on a circulation track while blowing hot air. The present invention relates to a drying device for clay tile molded materials, which is designed to dry under controlled conditions.

(Prior art) Although clay tiles have been manufactured since ancient times,
The manufacturing method is manual, and in recent years, mechanization has progressed up to the molding stage, but the drying process is still a natural drying method or a drying method similar to it. Most of it was dried in the sun.

Recently, the molding process has been automated and mass-produced, and solar drying cannot be applied, so we have no choice but to dry it naturally on the floor directly above the kiln, which takes 4 to 5 days, and then evaporates from the kiln downstairs. Drying was carried out by allowing the moisture in the substrate to evaporate naturally using rising high-temperature gas.

However, as production equipment for mass production becomes larger, the above-mentioned natural drying method on the floor takes too many days, and the drying space for the large amount of substrates being dried becomes vast, making it difficult to handle the drying process with just the space on the floor. In other places, there is insufficient residual heat, so residual heat drying is not possible, making it unsuitable for mass production of clay tiles, and this drying problem is a major bottleneck.
A solution to this problem was strongly requested in the tile industry. (Structure of the invention) In order to solve the above-mentioned problems all at once, this invention arranges drying carts so that they can run freely on a circuit that circulates in a fixed direction. A hot air inlet is provided on the exit side of the drying chamber, which is equipped with a drying chamber, and a hot air outlet is provided on the inlet side.A drying cart is operated facing the flow of hot air, and the exhaust heat of the kiln is utilized. , the hot air forcibly guided by a duct is blown in a closed drying room under rational control to perform forced drying, thereby obtaining ideal drying conditions and drying in a short time and completely unattended.

It is transferred to the return tracks 9, 9, towed by the towing cable 10 and proceeds in the downward direction of the arrow, transferred onto the traverser 6 on the entrance 3 side, sent in the direction of the arrow R, and loaded onto the dry substrate by the loading/unloading device 5.
', and transported to the firing process by a conveyor.The trolley that has been cycled again is loaded with a new undried material M by the loading device 5 onto the drying trolley 4, and sent to the drying room 1, as described above. Drying takes place.

Next, to explain the drying action in detail, hot air H is sent from a hot air source (not shown) through a hot air inlet duct 23 provided on the outlet lower side of the drying chamber 1 to an outlet in the main body 24 of the drying chamber 1. Ventilation ducts 21.21 and 22, 22, 22, 22, 22, 22, 22 and 22, 22, 22 and 22, 21.21, 22, 22 and 22, 22, 22 and 22, 22, 22 and 22.
When entering the main body 24 from..., the blocking wall 27.27
A force fan 31 installed facing inward in the first compartment 30 separated by 30 is used to force hot air H through the tile base M in the final stage of drying at that position while performing final drying. Then, it enters the facing compartment 30 arranged in a staggered pattern, is further energized by the biasing fan 31 there, passes between the tile base M of the drying cart 4 on the tracks 2, 2, and is staggered. The hot air H enters the facing compartment 30 arranged in the space 26 and is blown into the space 26 by the blower fan 32 installed in the direction opposite to the longitudinal direction (arrow P) of the drying cart 4 provided in the space 26. The direction is changed in the direction of the entrance 3, but it is blocked by the blocking wall 27 in front of it, changes its direction inward, passes between the tile bases M of the drying cart 4, and passes through the opposite sides arranged in a staggered manner. Section 30 of
The hot air H enters the interior and is redirected by the blower fan 32 installed in the direction of conveyance of the drying cart 4.
Blocked by the blocking wall 27, they change direction inward and enter the opposing compartments 30 arranged in a staggered manner.

In the space 26.26 of the main body 24, there is a compartment 3 having a blower fan 32 installed opposite to the conveying direction of the drying cart 4.
0.30, . . . are the blocking walls 27, 27. ...
Since the hot air H is provided in a staggered manner in the main body 24 in many pairs, the hot air H moves inside the main body 24 toward the population 3 in the direction of transportation of the 4 groups of drying carts 4 as shown by the arrows. While drying the upper tile base M, move it in a zigzag pattern, and
19.1 The air is collected in the air collection chamber 16 near the side shutter 14 and is discharged from the air outlet 18゜18, ...... 19.1
9 and then dissipates from the exhaust pipe 20 to the outside world.

Since the hot air H is blown into the drying chamber 1 from the output lower side of the drying chamber 1, the nearer the end of drying, the more the tile material M is hit by the hot air H with high temperature and low humidity, and becomes undried with a high moisture content on the side 3. The higher the tile base, the more it will be exposed to the relatively low temperature and high humidity hot air H.

This is because the hot air H is transported inside the drying chamber 1 in a direction opposite to the flow direction of the drying cart 4, so the temperature is absorbed by the tile material M on the way and gradually decreases, and the moisture in the tile material M is transferred to the hot air H. Evaporation causes humidity to rise gradually, and in the early stages of drying, the temperature is low and high humidity.
In addition, at the final stage of drying, hot air H with high temperature and low humidity is applied, so that ideal drying is performed and the product does not crack or warp.

FIG. 21 shows an example of a relationship diagram between the temperature t of the hot air H and the humidity in each part of the drying chamber 1.

(Example 2) In FIGS. 5 and 6, the hot air H sent in from the hot air inlet duct 23 provided on the outlet lower side of the drying chamber 1 is delivered to the spaces 26 on both sides in the main body 24 near the outlet lower. .26 air duct) 22.22 air outlet 21.21. ...

Some of the hot air H' is sent to an extension duct 37 that is connected and arranged above the ceiling 29 of the main body 24, and the other hot air H is sent to the air outlet 21° 21, 22.22. ... to enter the main body 24.

(Effects of the invention) With the above-mentioned configuration and operation, the present invention effectively guides hot air from an economical heat source that can be used, such as the exhaust heat of a kiln, to the vicinity of the exit of the drying chamber through the duct, and aligns it with the transport direction of the drying cart. Since the air is passed backwards through the closed drying chamber in a zigzag pattern and dissipated from the entrance side of the drying chamber to the outside world, the effect of rationally controlling the amount of heat, air volume, temperature, and humidity in the closed chamber is significant. As a result, the uneven drying of the product is eliminated, the quality is constant, the yield is extremely high, and the economic effect is tremendous.

In addition, this device's completely controlled forced drying greatly shortens the drying time. Conventional drying took about 4 days, but with this device, it takes about 8 hours, which can be done in a short period of time. The drying process has been completed, and the major bottleneck in mass production of clay tiles has been resolved, making mass production possible.The effect is once again tremendous.

Furthermore, since the present invention requires less space for drying, the extra space can be used to add other equipment, which is a unique advantage of the present invention.

In addition, since this invention dries in a closed room, there is no heat dissipation to the outside, and no heat radiation phenomenon occurs within the building where the drying room is located. Another great advantage is that there is no negative impact on equipment.
