しを防止する遮蔽装置に関するものである。[Detailed description of the invention] (Field of industrial application) The present invention relates to a shielding device that prevents outside air from entering through the seal portion of a trolley-type continuous heating furnace and prevents combustion gas from blowing out from inside the heating furnace. .

き出しを防止している。(Prior Art) As a method for heating objects of various shapes or large and heavy objects, a cart-type heating furnace, in which the materials to be heated are loaded on a cart and heated, is generally employed. In these cart-type heating furnaces, the cart and the furnace body are generally sealed to prevent outside air from entering the furnace and blowing out the gas inside the furnace.

板に干渉して台車の走行を不可能としていた。 There are two types of sealing methods: water sealing and sand sealing. In the sand seal method, a seal box placed below the cart is filled with sand, and a seal plate is inserted into the seal box to seal it. Sand spills from the seal box as the train runs, so sand needs to be replenished from time to time. In addition, in the water method, the seal box placed below the cart is filled with seal water and sealed by the seal plate and seal water. A partition plate is installed on the side to prevent water leakage. However, when the truck was running, the seal plate of the truck interfered with the partition plate, making it impossible for the truck to run.

る。 In order to solve this problem, in Utility Model Publication No. 57-18633, a notch is provided in the partition plate so that the seal plate installed on the bogie does not interfere with the partition plate, and a partition with a similar notch is provided inside the partition plate. A plate is provided, and a water supply passage is provided between the two partition plates, and a water supply port is provided below the drainage passage to drain the water, and a water supply port is provided in the seal box to maintain the water level above the lower end surface of the cutout of the partition plate. This seals the truck and the furnace body, allowing the truck to move.

（考案が解決しようとする問題点）しかしこれらの従来法であつても以下のような
問題点がある。(Problems to be solved by the invention) However, even these conventional methods have the following problems.

を図つている。 In other words, in a trolley-type continuous heating furnace in which a plurality of trolleys are connected and moved on rails using wheels installed on the bottom surface of the trolley using a drive device, a door that can be opened and closed at the entrance and exit of the furnace body is provided, and the furnace body is loaded on the trolley. This door opens the door for charging heated material into the furnace or extracts it out of the furnace, and closes the door when charging and extraction is completed, thereby reducing opening loss at the charging and extraction ports. .

しかし台車を複数連結して炉内を走行させる場

シール方式、あるいはサンドシール方式を採用し
ても扉により台車の上部は閉じられるが台車と炉
体間の炉幅方向の間隙は閉じることができない。 However, when a plurality of carts are connected together and run inside the furnace, even if the cart stops and the door is closed, the door remains on the top of the cart, and the door can only be closed up to the top of the cart. This is because even if the above-mentioned water seal method or sand seal method is adopted, the upper part of the cart can be closed by the door, but the gap in the oven width direction between the cart and the furnace body cannot be closed.

従つて台車と炉体の側部は間隙が生じ大気が炉
内へ侵入したり、あるいは炉内ガスが吹き出した
りして炉内熱効率が著しく悪化し、さらには被熱
材の過冷却が発生するという難点がある。 Therefore, a gap is created between the sides of the cart and the furnace body, allowing air to enter the furnace or gas inside the furnace to blow out, resulting in a significant deterioration in the thermal efficiency within the furnace and, furthermore, overcooling of the heated materials. There is a drawback.

である。(Means for Solving the Problems) The present invention is to load a heated material 1 on a cart 4, and surround the heated material 1 with a furnace body 2 lined with a heat insulating material. A seal box 5 is disposed at the lower side in the furnace width direction of a trolley-type continuous heating furnace that heats the furnace body 1, and a seal plate 6 disposed below the furnace body 2 is immersed in the seal box 5, and a seal plate 6 is inserted from below the trolley 4. A seal plate 7 is also provided vertically, and a shielding plate 9 for shielding the gap between the furnace body 2 and the carriage 4 from the outside of the furnace is sealed at the charging port and the extraction port in the seal portion formed by immersing in the seal box 5. This is a shielding device for a trolley-type continuous heating furnace characterized by being disposed on a plate 6.

が生じる。(Example) In FIGS. 1 and 2, the material to be heated 1 is loaded on a cart 4, the door 3 provided at the charging port of a continuous heating furnace is opened, and the cart 4 is charged into the heating furnace. Here, since a plurality of carts 4 are connected, a plurality of heated materials 1 loaded on the carts 4 are also arranged in a row in the heating furnace. For this reason, the heat-receiving material 1 loaded onto the trolley 4 from the charging port
When the heated material 1 is loaded, the heated material 1 is extracted from the extraction port while being loaded on the cart 4. At this time, the gap below the sides of the cart 4 and the furnace body 2 is
Sealing is achieved by immersing seal plates 6 and 7 placed below the furnace body 2 and carriage 4 into a seal box 5 placed below. Further, the charging port and the extraction port of the furnace body are also sealed by the door 3. but,
At the charging inlet and extraction port of the continuous heating furnace, even if the door 3 is lowered, the door 3 is lowered only to the upper surface of the cart 4, and a gap is created between the cart 4 and the furnace body 2 at the lower side of the furnace width direction.

As a result, the charging port and extraction port of the furnace body 2 can be sealed with the door 3, the sides of the furnace body 2 and the truck 4 can be sealed with the seal plates 6 and 7, and the sides of the furnace body 2 and the truck 4 can be sealed with the door 3. The lower part of the third part is sealed by a shielding plate 9 fixed to the seal plate 6, thereby preventing outside air from entering the furnace or blowing out of the furnace gas.
