Abstract

PROBLEM TO BE SOLVED: To solve a structural problem of a conventional cremains tray in a cinerator, having the configuration obtained by attaching a fireproof inorganic material to a dish-shaped frame constituted of a metallic plate member, that it has a structure to be subject to deform by heat as a temperature of the frame is quickly increased by a heating means, though a temperature of the inorganic material increases slower in comparison with the frame.SOLUTION: A framework section is constituted of a metallic grid-like member, and both sides of the framework section are wrapped with the fireproof inorganic material.

Description

      The present invention relates to an improvement of a cremation furnace facility in a factory.

      Generally, in a cremation furnace, a cocoon that arrives at a place is placed on a carriage and is put on a cradle in a cremation furnace after the last farewell of a relative. The firewood is cremated by a burner or electricity in the furnace, and the remains are received by a bone tray placed on the firewood stand. After being cooled sufficiently, it is pulled out from the crematory furnace and transferred to the cradle for picking up by relatives. Served on bone.

      Bone trays are generally constructed by attaching a fire-resistant inorganic material to a metal frame. However, since the inside of the cremation furnace is exposed to severe temperature changes such as a high temperature of 1000 ° C or higher during cremation and a low sound of around 50 ° C after completion, all the components in the furnace have the same temperature change. Exposed to. The bone saucer is no exception. However, the coefficient of expansion due to temperature differs greatly between metal and refractory inorganic material, and as a result, the damage is severe, often hindering access to and from the furnace. The work in the cremation furnace is hard work, and it is a series of heat and hard work. It can be said that it is a harsh work because the cremation carts in and out of the cremation furnace and the bone tray must be taken in and out in a high temperature atmosphere. In particular, the bone tray that has been deformed by heat in the furnace takes time to put in and out, and when thinking about the bereaved family waiting in the bone picking room, there is a conflict with the desire to deliver the remains to the bereaved family as soon as possible. There is.

      Such deformation of the bone tray is caused by the structure of the bone tray that has been generally used in the past. In other words, it is a shape in which a refractory inorganic material is attached to a dish-shaped frame made of a metal plate-like member. The temperature of the frame pair rises quickly with heating means, and the inorganic material lags behind the frame. As the temperature rises, the structure is easily deformed by heat.

      In the present invention, a skeleton portion is formed of a metal lattice member, and both sides of the skeleton portion are wrapped with a fireproof inorganic material.

      By comprising in this way, the temperature of the whole bone saucer rises and falls equally, there is no deformation | transformation by a temperature difference, and both front and back can be used effectively, and the durability of a bone saucer improves remarkably.

  A plan view with a part broken away   AA sectional view in FIG.   It is BB sectional drawing in FIG.

      A description will be given based on the preferred embodiment illustrated. 1 is an iron frame disposed so as to surround the periphery of the bone tray 10, 2 is a lattice-shaped core member, 3 and 4 are reinforcing members, 5 is a handle, and 6 is a fireproof inorganic material.

      The reinforcing material 4 is fixed to the inside of the frame 1 by an appropriate method such as welding. For the frame 1, an iron flat steel is effective. The reinforcing member 4 is preferably an iron round bar. The reinforcing material 4 is preferably inside the frame 1 and in the vicinity of the central portion of the thickness. The core member 2 has a size that fits inside the frame 1, and so-called expanded metal, punching metal, a wire mesh with a large wire diameter, and the like are effective. Lattice reinforcing bars for reinforced concrete can be used but are expensive. The core member 2 is preferably fixed by welding or the like at appropriate positions of the frame 1 and the reinforcing material 4.

      Even if only one core member 2 can be secured, it is effective to arrange the two core members in parallel so that the reinforcing member 4 is sandwiched from both sides in consideration of deformation over time. The two core members 2 are preferably fixed to the frame 1 and the reinforcing member 4 by welding or the like at appropriate positions.

      The reinforcing material 3 reinforces the deformation of the bone tray 10 in the longitudinal direction, and an iron flat bar can be used. The reinforcing material 3 is preferably arranged on both sides so as to sandwich the core member 2, and the width of the reinforcing material 3 is fixed to the inside of the frame 1 so as not to protrude in the thickness direction of the frame 1. It is necessary to cover the refractory inorganic material 6 with the refractory inorganic material 6.

      After the structural members are assembled in this way, the inside of the frame 1 is filled with a refractory inorganic material. Concrete is usually used as the refractory inorganic material. In order to further improve the heat resistance, heat-resistant high-strength concrete is effective. It is used after a curing period so that the refractory inorganic material is dried and has sufficient strength.

      The present invention can be used in general cremation furnaces and animal cremation furnaces. In addition, it can also be used in pottery and heating furnaces for scientific experiments.
