[Conventional technology]

Recently, large-scale thermal storage devices that utilize cheap late-night electricity have been gradually put into practical use as commercial heat sources. It has been done. This heat storage device is made by laminating magnesia refractory bricks in a lattice pattern. It consists of a heat storage body, a heat exchanger, and an electric heater, with air flowing between them. During rotation, low-temperature air sent by a fan is heated by an electric heater and becomes high-temperature air. and transfers heat to the heat storage body. On the other hand, during heat dissipation operation, the The air is heated in the heat storage element, reaches a high temperature, transfers heat to the heat exchanger, and is sent to the heat exchanger. The water is used as high-temperature water or steam.

A frame, 2 is a panel insulation material filled so as to wrap the same frame, 3 is made up of the above-mentioned parts, which are laminated in a lattice pattern. 4 is a panel exterior plate that covers the outside of the panel insulation material; 11 is a fire brick heat storage body; a top plate frame 7a attached to the upper part of the panel frame frame 1 with bolts; , 7b is the insulation material for the top plate that wraps around the same top plate frame, and A is the lower top plate. An air space that functions as an air flow path between the lower surface of the heat insulating material 7a and the upper surface of the heat storage body 3 The intermediate part 8 is a top plate exterior material that covers the outside of the upper top plate heat insulating material 7b. air flow path The surface of the heat insulating material is exposed around the circumference B of the space A.

0004 In the above device, during heat storage, high-temperature air heated by an electric heater is The structure is such that low-temperature air flows through A and during heat dissipation, flows through the same space. Above space The top plate part (top plate frame 11, top plate insulation materials 7a, 7b) forming the upper part of the storage It has a structure in which it is supported by a panel frame 1 of the heat tank. Figure 4 shows the top plate frame. A perspective view showing the structure of the frame 11, FIG. 5 is a perspective view showing the structure of the top plate frame 11. FIG. 3 is a perspective view of the attached state.

[Problem that the idea aims to solve]

The structure of conventional heat storage tanks has the following drawbacks. (1) At the top of the heat storage body 3, there is an air flow path space A, so the top plate part (frame + heat insulation Since the weight of the panel frame is supported by the panel frame, the support span becomes longer. The top frame is treated as a strength member, so it needs to be strong, and as mentioned above, it needs to be strong. Since the sea urchin is supported over a large span, it is heavy and has a complicated structure. (2) Since the inside of the heat insulating material 7a for the top plate has the surface of the insulating material exposed as it is, air cannot escape. The surface is broken and scattered by the flow of water, and it gets caught on the fins of the heater and heat exchanger. This can cause problems.

[0006] This invention was made to eliminate this drawback, and the top plate part has a lightweight and simple structure. It is intended to provide a heat storage tank which has the following properties and which does not cause loss or scattering of the heat insulating material for the top plate. It is.

[0007]

[Means to solve the problem]

The present invention solves the above problems and relates to a heat storage body having the following characteristics. It is something. (1) A recessed portion consisting of a heat storage body and a portion provided with a heat insulating material surrounding the side surface of the heat storage body; A heat storage tank in which an air flow path is formed by a top plate part with a heat insulating material covering the recessed part. , a plurality of groove-shaped refractory bricks are placed on the upper surface of the heat storage body so as not to obstruct air circulation. The above-mentioned top plate part is supported by the same firebrick. (2) a recessed portion consisting of a heat storage body and a portion provided with a heat insulating material surrounding the side surface of the heat storage body; A heat storage tank in which an air flow path is formed by a top plate part with a heat insulating material covering the recessed part. , attach the metal cover to the bottom surface of the top insulation material adjacent to the air flow path. to prevent the insulation material from being exposed to the air flow path.

[0008]

[Effect] (1) A groove-shaped refractory brick is placed above the heat storage body, and the weight of the top plate of the heat storage tank is supported by the heat storage body. As a result, the support span of the top plate is significantly shortened, and a frame for the top plate is no longer required. The insulation material is simply attached to the board. (2) Place a metal cover in contact with the insulation material at the boundary between the lower part of the insulation material for the top plate and the air flow path. By installing the insulation material in parallel, damage to the surface layer of the insulation material is prevented.
