ことは避けられなかった。An example of a discharge device for a vertical cooling furnace for powder and granular materials that requires airtightness is a discharge device for discharging cooled coke from a vertical cooling furnace of a coke dry extinguishing facility. In these facilities, it is important to reduce the height of the equipment in order to reduce equipment costs, but in the past, as in the case of the Soviet Union's Giprocoke, coke metal match type was used from the bottom of the vertical cooling furnace through the cut gate. The material is cut out, sealed airtight with a seal gun with a double seal valve, and once unloaded to Cork Wharf, it is continuously discharged to a delivery belt conveyor at the wharf gate, which avoids increasing the height of the entire discharge device. I couldn't.

は変シない。In addition, Japanese Patent Application Laid-Open No. 57-36184 proposes a method for continuous cutting using a vertical cooling furnace, but the airtight means for this method is also a seal hole with a double seal valve. There is no change in the fact that the height of the ejection device will be increased because of this.

点があるため、実用化は困難である。Furthermore, as shown in FIG. 1, a method is known in which a rotary valve 1 is placed directly in front of the powder outlet 5 of a vertical cooling furnace 2, but this method may cause crushing due to undesired coke entrainment.
It is difficult to put it into practical use because of the drawbacks of increased load, significant wear on the rotor 3° casing 4, and airtightness no longer guaranteed after a short period of operation.

ことを特徴とするものである。The present invention solves the above-mentioned problems and provides an inexpensive discharging device that can continuously discharge powder and granular materials without maintaining airtightness, and can further reduce the height of the entire equipment. A conveying device that continuously and quantitatively sends out the powder and granules is installed in an airtight chamber below the powder outlet of the shaped cooling furnace, and a rotary valve is installed at the discharge part of the conveying device. In addition, the conveying device is characterized in that it is configured to be able to control the supply amount to be smaller than the capacity of each chamber that constitutes the entire rotary valve.

への粉粒体のかみこみを防止できる。The vibrating feeder 7 has a particularly large particle size (200 trrs
Except for the above), the quantitative cutting performance is good, so that each space (room) composed of the rotor blade 8 and the side plate 9 will not be supplied in excess of its capacity. It is possible to introduce granules by controlling the feed rate. Furthermore, by providing the vibrating feeder 7 on the upstream side of the rotary valve 1, the supply port 5 of the rotary valve 1
It is possible to make the width of the falling flow rate of the granular material small with respect to the opening width a, and it is possible to prevent the granular material from being caught between the rotor blade 8 and the casing 4.

き、ローター羽根８先端部の摩耗条件を有利にできる。In addition, wear of the tips of the rotor blades 8 exposed to the falling flow of powder and granular material at the supply port 5 poses a problem, but the falling speed of the powder and granular material supplied to the supply port 5 of the rotary valve 1 by the vibrating feeder 7 is a problem. Since it can be minimized, it can be supplied softly and the wear conditions at the tip of the rotor blade 8 can be made favorable.

If high-pressure airtightness is required, use a super wear-resistant material such as silicon nitride ceramic for this part, or use a replacement structure and replace it periodically to maintain a high degree of airtightness. can.

な点は、本発明にとって重要であわ、排出装置のみなら
ず冷却炉全体を低くできるので設備費が低減される。Furthermore, the vibrating feeder 7 is inexpensive, has sufficient durability, and is highly practical. Particularly important for the present invention is the fact that the quantitative cutting device is con- nected, and not only the discharge device but also the entire cooling furnace can be made low-priced, thereby reducing equipment costs.

けた方がよい。The features of the roll feeder 12 are that it has a simple structure and is durable.
It has excellent personnel and is inexpensive. Further, as in the case of the combination of the apron feeder and the rotary valve, it is preferable to provide a small chute 11 at the discharge portion of the roll feeder 12 in order to prevent the rotary valve 1 from getting caught in the powder.
以上説明したように構成される本発明によれば以下の効
果がある。The present invention configured as described above has the following effects.
■ 竪型式冷却炉の気密を保ちなから粉粒体を連続的に
排出できるので、コークワーフやシールホン／ξ−等、
粉粒体を一時的に貯蔵する設備が不要である。■ Powder and granules can be continuously discharged while maintaining the airtightness of the vertical cooling furnace, so it can be used for coke wharfs, seal horns/ξ-, etc.
No equipment is required to temporarily store powder or granular material.
