水したもので回収量は原炭の３〜４％に相当する
量にのぼつている。このスラツジ炭を流動層ボイ
ラ内に安定に燃焼させるためにはスラツジ炭を一
定形状に成形させる必要がある。 With recent changes in the fuel situation, the value of coal as a fuel is being reconsidered, and as one method of utilizing coal, a method of using sludge coal as a fuel in a fuel device such as a fluidized bed boiler has been proposed.
This sludge coal is made by coagulating and precipitating fine particles in coal preparation wastewater using chemicals, and dewatering the coal under pressure using a filter press, and the amount recovered is equivalent to 3 to 4% of raw coal. In order to stably burn this sludge coal in a fluidized bed boiler, it is necessary to form the sludge coal into a certain shape.

一般造粒が必要な場合にはヌードル切断機を併
設する必要がある。(2) As a result of (1) above, natural cutting of the forming feed 6 becomes difficult to occur, and only strong string-like noodles (udon-like noodles) are produced. Therefore, if general granulation is required when continuous noodles are required, a noodle cutting machine must be installed.
このようなことはスラツジ炭を流動層ボイラで
燃料として使用するときには好ましくない。 This is not preferable when sludge coal is used as a fuel in a fluidized bed boiler.
例えば第７図に示すように、従来の成形用板４
の材料供給孔５から成形される成形供給物６は連
続した成形供給物６となるために、流動層ボイラ
の燃料として用いると流動が不安定になる。 For example, as shown in FIG.
Since the molded feed 6 formed from the material supply hole 5 becomes a continuous molded feed 6, the flow becomes unstable when used as fuel for a fluidized bed boiler.
この発明の目的はこのような従来技術の欠点を
除き自然切断が生ずるスラツジ炭として好ましい
粘着物押し出し装置を提案することにある。 The object of the present invention is to eliminate the drawbacks of the prior art and to propose a sticky material extrusion device which is suitable for sludge coal and which causes natural cutting.
要するに本発明は、成形用板に隣接して押し出
し羽根を配置し、かつ、この成形用板に成形供給

ードル状となつて排出される。 An embodiment of this invention will be explained with reference to FIG. Reference numeral 1 is the material inlet of the extrusion molding machine, reference numeral 2 is the material extrusion screw, reference numeral 3 is the extrusion blade,
4 is a forming plate. A large number of material supply holes 5 are bored in the molding plate 4, and when the material passes through these, the molding supply 6 is discharged from the exit side of the material supply holes 5 in the form of noodles.
５は材料供給孔、６は成形供給物、７は成形供
給物６のくびれ部である。 5 is a material supply hole, 6 is a molding supply, and 7 is a constriction of the molding supply 6.
この発明においては材料供給孔の拡大縦断面は
第４〜第６図に示すような形状をし、材料の下流

６は小間切れになつて落下する。 This shape prevents the material from being crimped by the extrusion blades 3 and increasing its density, and also due to the extrusion action of the extrusion blades 3 and the shape of the material supply hole 5 of the forming plate 4. Then,
As shown in FIG. 8, a constriction 7 is formed in the forming supply 6 discharged from the material supply hole 5, and due to this constriction 7 and the weight of the forming supply 6, the forming supply 6 is broken into small pieces. and fall.

ことが実験でたしかめられた。 According to the results of experiments, the effective length w of the material supply hole 5 was preferably 0 to 3 mm. It has been found that this constriction phenomenon occurs when the extrusion blade 3 presses the material into the material supply hole 5. It has been confirmed through experiments that the dimension between the constrictions 7 of the extruded noodles, ie, the length (l) of the constrictions 7, is expressed by the following formula.
