支持されている。 In this device, raw material 15 is distributed from a conveyor 16 through a rotating chute 1 to a fixed hopper 17, and then charged into a vertical furnace through a gate valve 18, sequentially through a seal valve 19, a small bell 20, and a large bell 21. Ru. However, when the raw material is charged into the fixed hopper 17 via the rotating chute 1, the conveyor 16
Due to the influence of
As shown in the figure, since the falling conditions from the conveyor 16 to the discharge port of the rotating chute 1 are different at positions A and B, the distribution of the raw material in the fixed hopper 17 has uneven mountain shape and particle size distribution. This uneven distribution cannot be completely eliminated even if the raw materials are sequentially charged into the furnace through the small bell 20 and the large bell 21, resulting in unstable furnace conditions and increased fuel costs. This poses a serious operational obstacle. In FIG. 4, a small bell 20 and a large bell 21 are supported by a bell drive rod 22.
原料不均一分布の発生防止策としては過去に
種々の流量調整器の考案がなされて来た。第６図

By appropriately selecting the opening degree of the flow rate regulator 4, the directionality of the conveyor can be eliminated, and the charging distribution of raw materials can be greatly improved. According to this method, the fixed hopper 1
The uniform distribution of the raw material 7 is very preferable in terms of operation because it can be uniformly charged into the furnace in the same manner as explained in FIG. 4 above. However, in this system, the opening/closing mechanism of the flow rate regulator is complicated, as will be explained below with reference to FIG. 7, and this is a drawback in terms of equipment costs and maintainability.

れる。(Effects of the invention) According to the invention, the installation of a flow rate regulator at the outlet of the rotating chute, that is, the improvement of operation by uniform distribution of raw materials, can be achieved with a simple drive mechanism, which reduces equipment costs and maintainability. Very preferred. Furthermore, the present invention has the advantage that it can be easily installed in existing equipment because the drive mechanism is simple. In the conventional drive system explained in FIG. 7, a double-tooth large gear 29 and an annular bearing 3 supporting the gear
Therefore, when installing the flow regulator, it was necessary to temporarily remove the bell drive rod 22, install a newly modified swing chute, and then reinstall the rod. This resulted in a large-scale construction work, increased construction costs, and required long periods of suspension of operating equipment. According to the new drive method of the present invention, the above-mentioned drawbacks of the conventional method are eliminated, and the desired flow rate can be easily achieved by additionally installing the flow regulator and its drive device on the existing swing chute without temporarily removing the bell drive rod. You can reach your goal. In addition, in this method, the flow rate regulator cannot be opened and closed during the rotation of the rotating chute as in the conventional method explained in Fig. 7, but this does not necessarily impede the uniform distribution of the charged material. No. In other words, raw materials are normally charged intermittently in batches due to the charging sequence that involves equalizing the exhaust pressure of the gas in the hopper, so the opening degree of the flow rate regulator is controlled using each charging batch as a unit. This sufficiently improves the charging distribution.

化できるため極めて好ましい条件が付与される。 As explained above, according to the present invention, in order to improve raw material distribution, it is possible to install a flow rate regulator with a very simple mechanism, which not only reduces equipment costs and maintenance costs, but also allows modification of existing equipment. Therefore, even when installing a flow rate regulator, the construction work can be simplified, which provides extremely favorable conditions.
