Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a simple dryer for drying a moisture-containing solid desiccant.

[Prior Art] Conventionally, silica gel as a desiccant is white hard fine particles obtained by neutralizing an aqueous solution of water glass with hydrochloric acid.
It is used by solidifying.

[Problems to be solved by the invention] Since this desiccant is extremely hygroscopic and harmless, it has a wide range of use and its used moisture content is 150 ° C.
It is regenerated by drying before and after, and can be used repeatedly. However, since the price is extremely low, it is rarely recovered and is thrown away, and there is a point that effective use of resources is insufficient.

The present invention has been made to solve this problem, and an object thereof is to provide a simple dryer capable of easily drying a moisture-containing solid desiccant.

[Means for Solving the Problems] A simple desiccant dryer of the present invention made to achieve the above object has an electric wire insertion hole in a side wall thereof, and has an exhaust amount in an upper opening and a lower opening. A bottle body that covers the cap-shaped upper and lower lids, each of which has a ventilation port that can freely adjust the intake air amount, and a heater with a thermostat for drying the moisture-containing solid desiccant inside the bottle. And a net-shaped heat-resistant bag body which is hung from above the opening edge of the bottle and above the lower opening with a gap therebetween.

[Operation of the device] A mesh-shaped heat-resistant bag body having a built-in heater with a thermostat is hung above the rim of the upper opening of the bottle with a gap above the opening, and is provided on the heater and the side wall of the bottle. Connected with the electric wire through the inserted hole, the moisture-proof solid desiccant is stored in the heat-resistant bag, and the exhaust volume is set in the upper opening of the bottle.
If you cover each cap-type lid with a vent that allows you to adjust the amount of intake air in the lower opening, and heat the moisture-containing solid desiccant to a predetermined temperature by energizing the heater, the water vapor will rise above the bottle. Therefore, if the vent of the upper lid is made large and the vent of the lower lid is slightly opened, the water vapor is discharged from the vent of the upper lid. If the amount of water vapor released becomes small, the air pressure inside the upper part of the bottle will be lowered if the vent of the lower lid is enlarged, and there will be a gap between the bag and the lower opening of the bottle. By having
A large amount of air rises through the mesh of the bag body, and the residual moisture inside the bag body is released all at once, thus completing the drying of the desiccant.
Since the heater inside the bag has a thermostat, it does not generate heat above a predetermined temperature.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a sectional view showing the entire structure of the embodiment,
Reference numeral 1 denotes a container for a desiccant simple dryer, which is a bottle body formed in a horizontal body having an upper opening 1c and a lower opening 1d having wide mouths at the top and bottom. Reference numeral 1b is an insertion hole for an electric wire which is opened at the top and bottom of the side wall 1a of the bottle body 1. Reference numeral 1f denotes an upper lid body which covers the upper opening 1c of the bottle body 1 in a cap type, and 1g denotes a lower lid body which also covers the lower opening 1d in a cap type. The upper lid 1f controls the displacement
The lower lid 1g has a vent 1e that allows you to freely adjust the intake air volume.
have. (Note that the lid body will be described later.) 2 is glued inside the bottle body 1 to the rim 1h of the upper opening 1c of the bottle body 1 and a gap is formed above the lower opening 1d from the rim 1h.
It is a net-shaped heat-resistant bag body that is hung via 1i. The heat-resistant bag body 2 has a built-in heater 2b with a thermostat, and the heat generation temperature of the heater 2b is kept at about 150 ° C during use. . 2a is a silica gel as a moisture-containing solid desiccant contained in the heat-resistant bag 2. In addition, 2c in the figure shows a plug for connection with a power supply.

FIG. 2 shows the relationship between the bottle body 1 and the lid bodies 1f and 1g, but the lid body will be particularly described. The upper lid 1f and the lower lid 1g have the same shape, and a circular cap body 3 and a disc 4 are provided.
Is mounted, and the disc 4 is rotatably fixed to the central portion from above the disc 4 with a screw 5, and the cap body 3 of the cap type is
A vent hole 3a is opened in the peripheral portion, and the vent hole 3a communicates with the openings 1c and 1d of the bottle body 1 from the inside of the cap body 3. The bottom of the cap body 3 is provided with a ring-shaped wall body 3b for inserting into the openings 1c and 1d of the bottle body 1. The disc 4 is provided with a knob 4a for rotating the disc 4 at one corner on the disc 4, and a tongue piece 4b for making the opening area of the vent 3a of the cap 3 larger than the peripheral edge of the disc 4b. Is installed vertically.

Next, the usage method will be described.

(A) Cover the bottle 1 with the lower lid 1g.

(B) The moisture-containing solid desiccant 2a is filled and stored in the heat-resistant bag 2 through the upper opening 1c of the bottle 1 with a space above.

(C) The upper opening 1c of the bottle 1 is covered with the upper lid 1f, and the vent 1e of the upper lid 1f is made large and the vent 1e of the lower lid 1g is made small.

(D) Next, turn on the heater 2b to turn on the moisture-containing solid desiccant 2a.
To heat.

(E) When the amount of water vapor discharged from the ventilation port 1e of the upper lid 1f becomes small, the ventilation port 1e of the lower lid 1g is opened to allow the outside air to circulate upward from the lower lid 1g all at once. The residual moisture of the wet solid desiccant 2a is released.

(F) After the completion of drying, the heater 2b is turned off, the bottle 1 is reversed, and the wet solid desiccant 2a is taken out and cooled.

By using the desiccant simple dryer of this embodiment, the wet solid desiccant can be completely dried easily, and the heater is equipped with a thermostat, which is safe.

[Effects of the Invention] The present invention not only has an extremely simple structure and is easy to manufacture, but also has a high drying capacity and is capable of completely drying a moisture-containing solid desiccant, which is beneficial for resource reuse. It has a practical effect.
