ている。BACKGROUND ART Water heaters, instantaneous water heaters, heating devices, and the like that heat water or air using the sensible heat of a heated solid heat storage body are known. For example, Japanese Patent Application Laid-Open No. 63-105362 describes a solid heat storage body, an electric heater that heats the solid heat storage body to store heat, a blower that blows air toward the solid heat storage body, and a blower that blows air toward the solid heat storage body. An electric water heater is disclosed that includes a heat exchanger that exchanges heat between the air heated by the solid heat storage body and water and converts the water into hot water.
No. 311046 discloses a heat medium duct that circulates a heat medium between a heat storage body that incorporates a heat generating body and can store the electric energy of the heat generating body as thermal energy, and a heat exchanger that heats water. A heat storage type hot water supply device is disclosed.

、けい石煉瓦、鉄酸化物煉瓦等のセラミックス煉瓦、砕
石、砂質土壌、純鉄、鋳鉄等の金属材料等が挙げられて
いる。Solid heat storage bodies that can be used in these water heaters include ceramic bricks such as magnesia bricks, alumina bricks, chrome bricks, silica bricks, and iron oxide bricks, crushed stone, sandy soil, and metals such as pure iron and cast iron. Materials etc. are listed.
上記の固体蓄熱体のうち、セラミックス煉瓦は、蓄熱体
としての高比重、高比熱の特性を得るために、成形圧力
の増大、焼成温度の野温度化、長時間化が必要であり、
また、耐火煉瓦等と同じ煉瓦製造工程により製造される
ので、製造条件の制約が大きく、製造コストも高いとい
う問題があった。Among the solid heat storage bodies mentioned above, ceramic bricks require increased molding pressure, lower firing temperature, and longer firing time in order to obtain the characteristics of high specific gravity and high specific heat as a heat storage body.
Furthermore, since they are manufactured using the same brick manufacturing process as refractory bricks, etc., there have been problems in that manufacturing conditions are severely restricted and manufacturing costs are high.
また、砕石や砂質土壌は、一定形状の単体として用いる
ことができず、金属材料は製造コストが高いという問題
があった。In addition, crushed stone and sandy soil cannot be used as single bodies of a certain shape, and metal materials have the problem of high manufacturing costs.
本発明において解決すべき課題は、製造条件の制約が少
なく、かつ、安価な固体蓄熱体を得ることにある。The problem to be solved in the present invention is to obtain an inexpensive solid heat storage body with fewer restrictions on manufacturing conditions.
本発明のセラミックス蓄熱体は、鉄分含有量が50〜8
0重量%の鉄鉱石100重量部に対して成形・焼結助剤
と有機添加剤のいずれか一方または両方を合計で0.1
〜40重量部配合し、成形した後、650〜1500℃
で焼成したものである。The ceramic heat storage body of the present invention has an iron content of 50 to 8
A total of 0.1 of either or both of a forming/sintering aid and an organic additive per 100 parts by weight of iron ore containing 0% by weight.
After blending ~40 parts by weight and molding, 650~1500℃
It was fired in
本発明のセラミックス蓄熱体は、鉄鉱石を主原料とした
ものである。鉄鉱石は、安価に人手でき、しかも蓄熱能
は従来の高価な酸化鉄を主成分とした鉄酸化物煉瓦と大
差ない。The ceramic heat storage body of the present invention uses iron ore as a main raw material. Iron ore can be produced by hand at low cost, and its heat storage capacity is not much different from conventional, expensive iron oxide bricks, which are made mainly of iron oxide.
鉄鉱石としては、代表的なものとして磁鉄鉱、赤鉄鉱、
磁鉄鉱等があるが、すべての鉄鉱石を用いることができ
る。これら鉄鉱石の鉄分含有量が50%未満だと蓄熱能
が不足し、80%超の高品位の、鉄鉱石は人手が困難な
ので、鉄分含有量が50〜80%のものを用いる。Typical iron ores include magnetite, hematite,
There are magnetite, etc., but all iron ores can be used. If the iron content of these iron ores is less than 50%, the heat storage capacity will be insufficient, and high-grade iron ores of more than 80% are difficult to handle, so those with an iron content of 50 to 80% are used.
この鉄鉱石100重量部に対して、成形・焼結助剤上有
機添加剤のいずれか一方または両方を合計で0.1〜4
0重量部配合する。成形・焼結助剤と有機添加剤のいず
れか一方または両方を少なくとも0.1 重量部配合す
ることにより、原料粉体に可塑性やグリン強度を与え、
粒子を均一に分散させ、粒子間の潤滑性および離形性を
与え、成形を容易にする。また、焼成時に液相を生成し
て焼結を促進させる。しかし、配合量が40重量部を超
えて鉄鉱石の割合が減少すると、蓄熱能が不足するので
、配合の上限は40重量部とする。For 100 parts by weight of this iron ore, a total of 0.1 to 4% of one or both of a forming/sintering aid and an organic additive is added.
Add 0 parts by weight. By blending at least 0.1 part by weight of either or both of a molding/sintering aid and an organic additive, plasticity and green strength are imparted to the raw material powder,
Uniformly disperses particles, provides interparticle lubricity and mold releasability, and facilitates molding. In addition, a liquid phase is generated during firing to promote sintering. However, if the blending amount exceeds 40 parts by weight and the proportion of iron ore decreases, the heat storage capacity will be insufficient, so the upper limit of the blending amount is 40 parts by weight.
成形・焼結助剤としては、長石、粘土、フリット等を用
いることができる。As the shaping/sintering aid, feldspar, clay, frit, etc. can be used.
また、有機添加剤としては、ポリビニル・アルコール、
カルボキシ・メチル・セルローズ、メチル・セルローズ
、アクリル酸系重合体等の解膠剤、結合剤、可塑剤、潤
滑剤として作用するものを用いることができる。これら
の有機添加剤は、配合量が多過ぎると焼成後の気孔率が
増加し多孔質になって蓄熱能が低下するので、配合割合
は5重量部以下とすることが好ましい。In addition, organic additives include polyvinyl alcohol,
Those that act as deflocculants, binders, plasticizers, and lubricants, such as carboxymethyl cellulose, methyl cellulose, and acrylic acid polymers, can be used. If the amount of these organic additives is too large, the porosity after firing will increase, the material will become porous, and the heat storage capacity will decrease, so the mixing ratio is preferably 5 parts by weight or less.
配合物の成形は、塑性成形法、加圧成形法、鋳込み成形
法等の、−数的なセラミックスの各種成形法を採用する
ことができる。For molding the compound, various ceramic molding methods such as plastic molding, pressure molding, and cast molding can be employed.
成形後は、窯炉内で650〜1500℃に加熱して焼成
する。After shaping, it is heated and fired at 650 to 1500°C in a kiln.
