Description
【発明の詳細な説明】 ＜産業上の利用分野＞ この発明は圧縮により含有水分を排除する必要のある
産業廃棄物特に製紙粕を脱水と定量供給とを同時にして
燃焼装置に供給する装置に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial application field> The present invention relates to a device for supplying industrial combustion waste, particularly papermaking lees, which requires removal of water content by compression to a combustion device while simultaneously dehydrating and quantitatively supplying the waste. .

するもので、この対策も必要とするまである。<Conventional technology and its problems> The purpose of the conventional feeder for papermaking lees is to continuously discharge (supply) quantitatively. Therefore, as shown in FIGS. A device using a single-axis or single-axis screw feeder is employed. However, in this case, no consideration is given to the quantitative supply of dewatering in the process of continuously discharging high-moisture papermaking lees with a screw feeder to reduce the water content of the discharged lees and to achieve more stable combustion. . This means that the quantitative supply from the hopper to the skewer is based on the shape of the hopper and the bridging inside the hopper as a major factor in the supply of the material from the hopper to the skewer.
また、製紙粕の脱水機としては、従来第７図に示すよ
うな、やはりスクリユーフイーダを使用するものもある
が、この種の脱水機はあくまでも脱水のみを目的とした
ものであるため排出後（脱水後）の水分は非常に小さく
なるように設計されており、このため、所要動力が非常
に大きいことより長時間の連続定量排出に対する配慮、
すなわち使用による利得としての電力費の低減という点
に対する配慮が不足していると言える。また定量供給す
るためには別の装置を必要とするという問題もある。As a dewatering machine for papermaking cakes, there is also a conventional one which uses a screw feeder as shown in FIG. 7; however, this type of dewatering machine is only for the purpose of dewatering. The water after (dehydration) is designed to be very low, so that the power required is very large, so consideration for long-term continuous quantitative discharge,
In other words, it can be said that there is a lack of consideration for reducing the power cost as a gain due to use. In addition, there is a problem that another device is required to supply a fixed amount.
上記の２つの従来技術は、定量排出と脱水を個々に達

費が増大するという問題点があつた。The above two prior arts are technologies for individually achieving the quantitative discharge and the dehydration, and no consideration is given to having both functions, and two devices are required to satisfy both. Need to be installed separately, which causes problems such as an increase in equipment cost, an increase in installation space, and an increase in power cost as utility.

水型廃棄物供給装置を提供することにある。<Object of the Invention> An object of the present invention is to provide a dewatering-type waste supply apparatus having both a continuous quantitative discharge function and a dehydration function in order to solve the above-mentioned problems of the conventional technology.

水型廃棄物供給装置である。<Summary of Means> In short, the present invention relates to a wing pitcher of a screw which is connected to a lower part of a hopper for storing a material capable of separating a liquid by compression and which can discharge the separated liquid from its outer surface, and inserts the cylindrical body. An outlet cone is provided so as to gradually reduce the volume toward the discharge end, and has an apex on the discharge end side of the screw so that the top is opposed to the transfer direction of the transported object and elastically enables sliding displacement on the screw shaft. And a dewatering-type waste supply apparatus provided with a scraper blade for scraping off a transported object downstream of the outlet cone.
＜実施例＞ この発明の一実施例を第１図及び第１図のＢ部詳細を
示す第２図及び第３図、第４図により以下に示す。<Embodiment> An embodiment of the present invention will be described below with reference to FIGS. 2, 3 and 4 showing details of the portion B in FIG. 1 and FIG.
スクリユーの羽根は、ホツパー下部は第３図、第４図
に示す如く羽根径Ｄ、羽根ピツチＰ、軸径は変化なしと
する。分離した水をケーシング外に排出できる多孔のケ
ーシング５で脱水を行なうようにした。As for the screw blades, the blade diameter D, the blade pitch P, and the shaft diameter are unchanged at the lower part of the hopper as shown in FIGS. The dewatering was performed in the porous casing 5 capable of discharging the separated water out of the casing.
第２図に示すごとくケーシング５に対応するスクリユ
ーはホツパー側よりD2＞D1、ピツチはP2＞P1、軸計は変
化なしとし、羽根ピツチ間の容積（１ピツチの羽根間容
積をピツチ容積と称す。）が減少する第１段目の脱水段
階とする。ついで排出端側に羽根なし部11を設け第２段
目としての排水を行なう。As shown in FIG. 2, the screw corresponding to the casing 5 is D 2 > D 1 from the hopper side, the pitch is P 2 > P 1 , the axle is unchanged, and the volume between the blade pitches (the volume between the blades of one pitch is This is the first dehydration stage in which the pitch volume is reduced. Next, a bladeless portion 11 is provided on the discharge end side to perform drainage as a second stage.
ホツパー下部のスクリユーは数ピツチあり製紙粕はい
わゆるブリツジングすることはない。従つてケーシング
５の接続部には円滑に少なくとも１ピツチ分の製紙粕が
充分に羽根間に充填して送り込まれるのでスクリユーが
脱水前の状態で供給されることとなる。なおケーシング

をもつ。なおホツパー下部で中間の数ピツチはホツパー
内製紙粕の前記接続部側の製紙粕レベルのある値から順
次機能してくる。The screw at the bottom of the hopper has several pitches and the papermaking lees do not cause so-called bridging. Therefore, at least one pitch of papermaking residue is sufficiently filled between the blades and sent to the connection portion of the casing 5, so that the screw is supplied before dewatering. The screw blade on the side wall opposite to the connection of the casing also has a function of supplying papermaking lees. Note that the middle pitches at the lower part of the hopper function sequentially from a certain value of the level of papermaking lees on the connection side of the papermaking lees in the hopper.
これはスクリユー排出の場合（輸送）の特質として観
察により確認された処である。This is a place confirmed by observation as a characteristic of screw discharge (transportation).
次にこの連続定量排出されている高水分製紙粕（以下
単に粕と称す）の脱水の機能について説明する。前述の

であるが、このケーシング部に当る部のスクリユー羽根
１はケーシング部の出口側に行くに従い羽根径をD2＞
D1、羽根ピツチをP2＞P1と徐々に小さくしている。Next, the function of dehydrating the high-moisture paper waste (hereinafter simply referred to as the waste) discharged continuously and quantitatively will be described. As described above, the high-moisture residue charged into the hopper 4 is conveyed to the casing 5 on the discharge side by the screw feeder. The screw blade 1 at the portion corresponding to the casing portion is connected to the outlet side of the casing portion. As you go, change the blade diameter to D 2 >
D 1 , the blade pitch is gradually reduced to P 2 > P 1 .
このように羽根径と羽根ピツチを徐々に小さくしてい

ることにより、羽根間に入つている粕の容積を減少させ
る、すなわち圧縮することにより第１段階の脱水を図る
ことにある。またこれだけでも予定する脱水はできる。The reason why the blade diameter and the blade pitch are gradually reduced in this way is that the volume between the blades (pitch volume) is gradually reduced, thereby reducing the volume of the lees interposed between the blades, that is, compressing. Thus, the first stage of dehydration is intended. In addition, the dehydration can be performed by this alone.

ることができるようにしたものである。The partially dehydrated cake is conveyed to the outlet of the casing portion. In the present invention, the second stage of dehydration is further performed at this outlet. That is, a bladeless portion 11 is provided at the outlet portion, and since there is no screw blade 1 to pass this portion (length L), there is no conveying force by the blade, so that the blade is sent from the downstream side. Leafless part 11
The stagnant cake passes through it under the force of pushing out the stagnant cake, and is discharged while being further compacted (compressed) and dewatered. During the second stage of dehydration,
As means for further improving the dewatering effect, an outlet cone 8 is provided at the outlet 3 to adjust the gap with the outlet casing.
The outlet cone 8 can be elastically moved by the ridge 7. For this purpose, the exit cone 8 is
Even when the operation is performed with the gap 1 set to the optimum position, the discharge and dehydration characteristics may change depending on the properties of the lees. Therefore, it is possible to always obtain a constant discharge characteristic.

In the prior art, two apparatuses each having a single function must be installed. Dehydration and provision and supply can be performed by a single device, which has the effect of reducing equipment costs, installation space, and power costs as effectiveness.
