[Industrial applications]

 The present invention relates to a treatment material charging / extracting apparatus for a batch type fluidized bed furnace.

[0002]

[Prior Art]

 Conventionally, batch type fluidized bed furnaces have been used for heat treatment of steel parts or heat removal of adhered organic matter. In this batch type fluidized bed furnace, a lid for opening and closing the upper opening of the fluidized tank forming the fluidized bed is provided inside, and when the processing material is charged, the processing material is completely loaded in the fluidized bed. When the treatment material is extracted, the lid body is closed and then the lid body is completely opened, the treatment material is extracted from the fluidized bed, and then the lid body is closed. is there.

[0003]

[Problems to be solved by the device]

 In this way, the lid is opened prior to the charging of the treatment material into the fluidized bed or the extraction from the fluidized bed, that is, the opening time of the fluidized bed furnace is long, the heat release is increased, and the fluidized particles are removed. (Sand) scattering increases. Further, when the adhered organic matter is removed by heating, there is a problem that the emission of flammable fumes increases and the working environment deteriorates. Therefore, it is an object of the present invention to provide a treatment material charging / extracting device for a batch type fluidized bed furnace which can shorten the opening time of the opening of the fluidized bed furnace with a simple mechanism.

 In order to achieve the above object, the present invention relates to a batch type fluidized bed furnace equipped with a treatment material charging / extracting device of a batch type fluidized bed furnace, which includes a lid for opening and closing an upper opening of a fluidized tank. A platform having a traveling rail is provided above the traveling rail, a traveling carriage is provided on the traveling rail, and a processing material supporting member is hung and held on the traveling carriage so that the processing material supporting member can be lifted up and down. The structure is such that a lid with a heat insulating material is provided on the lower surface side.

【Example】

 Next, an embodiment of the present invention will be described with reference to FIG. FIG. 1 shows a fluidized bed type heating and cleaning apparatus 1 equipped with a processing material charging / extracting apparatus according to the present invention, which is roughly composed of a furnace main body 2, a loading tray 14, and a processing material charging / extracting apparatus 15.

The furnace body 2 is lined with a heat insulating material 3, and inside the furnace body 2, a flow tank 4 having an open top and a cleaning tank 12 are arranged. Further, in the vicinity of the flow tank 4, the furnace body 2 is provided with a rotatable lid 6 on the lower surface side of which a heat insulating material 7 is stretched, and an upper opening 5 of the flow tank can be opened and closed. In the lower part of the fluid tank 4, a fluidizing gas supplied from a blower (not shown), for example, air is jetted upward to fluidize fluid particles 8 such as alumina in the fluid tank 4 to form a fluidized bed 9. The gas distribution means 10 is provided. Further, a sealing material 11 is provided on the upper end of the flow tank 4. Hot water W is stored in the cleaning tank 12, and the hot water W is supplied to the nozzle 13 by a circulation pump (not shown) and circulates in the cleaning tank 12.

If the heater (not shown) or the processing material S is an organic substance-adhered component, the fluidized tank 4 and the cleaning tank 12 are provided with an incinerator that burns and incinerates the organic gas generated in the fluidized tank 4. It is designed to be heated by exhaust heat.

The treatment material charging / extracting device 15 includes a pedestal 16 having a traveling rail 17 provided above the flow tank 4, the cleaning tank 12, and the cargo receiving base 14, and traveling traveling on the traveling rail 17. It is composed of a carriage 18 and a processing material support member 19 suspended from the traveling carriage 18 so as to be able to move up and down, and an insulating material 21 is stretched on the lower surface side above the processing material support member 19. It has a lid 20 capable of opening and closing the opening 5 of the flow tank 4.

Next, the operation of the treatment material charging / extracting device having the above-described configuration will be described. Now, the fluidized tank 4 is heated by a heater or the like (not shown), and the fluidized particles 8 are fluidized by the fluidizing air from a blower (not shown) to form a fluidized bed 9, while the cargo bed 14 is Then, a component (hereinafter referred to as a treatment material) S to which an organic substance is attached is loaded on the treatment material support member 19, and the treatment material S is held at a position shown by a solid line in the drawing by a hoist (not shown) provided on the traveling carriage 18. It is assumed that it is waiting.

First, the flow tank lid 6 is rotated upward to open the opening 5 of the flow tank 4, and at the same time, the traveling carriage 18 is moved above the flow tank 4 to drive the hoist. Thus, the processing material S is charged into the fluidized bed 9 of the fluidized tank 4. Simultaneously with the completion of the charging, the lid 20 attached to the processing material support member 19 closes the opening 5 of the flow tank 4. Then, when the treatment material S is charged into the fluidized bed 9 and heated with the fluidized particles 8 as a heat medium, the organic matter attached to the surface thereof is immediately thermally decomposed or vaporized to contain this organic gas. The exhaust gas is removed from fluid particles contained in the exhaust gas by a cyclone from an exhaust port (not shown), and then burned by an incinerator or the like (not shown).

After heating for a predetermined time, the hoist is driven to pull up the processing material S above the fluid tank 4, and the traveling carriage 18 travels to be positioned above the cleaning tank 12. At the same time, the fluid tank lid 6 is rotated to close the opening 5 of the fluid tank 4. Further, the treated material S heated as described above is immersed in the warm water W in the cleaning tank 12 by driving the hoist, so that the adhered residue and the adhered fluid particles 8 are removed from the surface of the treated material S. Clean and remove from. After that, the treatment material S is pulled up from the warm water W, loaded and unloaded on the load receiving base 14, a new treatment material is loaded, and the above operation is repeated.

During cleaning of the processing material S, loading and unloading on the loading tray 14, loading of the processing material S, etc., the opening 5 of the fluid tank 4 is closed by the fluid tank lid 6, so that heat dissipation and sand Scattering is prevented. In the above description, the fluidized bed furnace that heats and cleans the organic matter adhering to the processing material S has been described, but the same applies to the fluidized bed furnace that heats and heats the processing material.

[Effect of the device]

 As is clear from the above description, according to the present invention, since the lid for opening and closing the opening of the fluid tank is provided on the upper portion of the treatment material support member, the treatment material flows into the fluidized bed at the same time. The opening of the tank is closed and the treatment material is charged into the fluidized bed as in the past, but it is not closed after a predetermined time.The opening time of the fluid tank is shorter than that of the conventional one, reducing heat dissipation and scattering of sand. Can be reduced. In addition, when the treated material is an organic substance attached, the emission of the vaporized organic gas can be reduced and the working environment can be improved accordingly.

Further, according to the present invention, when the processing material is extracted from the fluidized tank, the opening of the fluidized tank is also opened. The opening time of the fluidized tank is shortened in this respect as well because it does not open prior to discharge.
