つた。 Conventionally, a so-called Fourdrinier papermaking method has been known as one of the methods for producing inorganic plate materials. This fourdrinier papermaking method uses a belt conveyor equipped with a dewatering device to transport and dehydrate cement slurry of a constant thickness, and then molds it into a molded product shape. Although it has the advantage of being able to be manufactured by assembly line operations, it has the problem that the dehydration process takes time and it is difficult to expect an improvement in manufacturing efficiency per unit time.

問題があつた。 In other words, in the Fourdrinier method, cement slurry with a water content of about 80% is generally fed down onto a belt conveyor, and a suction force of about 300 mmhg is applied to it.
The water is dehydrated while being transported on a conveyor.
To dehydrate this to a moisture content of about 60%, it takes about 3 minutes at a belt conveyor speed of 10 m/min, and the final moisture content is 50-45%.
In order to do this, it was necessary to further perform compression dehydration using a press machine, which caused the problem that the molding speed could not be increased.

置されて成ることを特徴とするものである。 In view of the above-mentioned drawbacks, this invention aims to shorten the belt line required for dewatering, improve manufacturing efficiency, and provide a preliminary dewatering device for an inorganic plate manufacturing equipment that can perform effective dewatering at low cost. This is an inorganic belt conveyor that dewaters cement slurry of a certain thickness while conveying it, and a press device that performs final dewatering of the cement slurry at the end of the belt conveyor. In the plate manufacturing device, a mounting plate having a water absorption surface is provided between the end of the belt conveyor and the press device, and a load plate for compressing cement slurry is placed on the mounting plate so as to be transferable. It is characterized by:

載置されて構成されている。 The preliminary dewatering device (hereinafter simply referred to as the pre-dehydrating device) A in the inorganic board manufacturing equipment of this invention is:
A belt conveyor 2 has a hopper 1 at its starting end that supplies cement slurry with a moisture content of about 80%, and dewaters the cement slurry B by a suction device 2A while transporting the cement slurry B supplied to a constant thickness T from the hopper. In an inorganic plate manufacturing apparatus equipped with a press device 3 for finally dewatering the cement slurry B at the end of the belt conveyor 2, a water absorption surface 4A is provided between the end of the belt conveyor 2 and the press device 3.
A loading plate 4 is provided, and a load plate 5 for compressing a cement molded product is placed on the loading plate 4 so as to be transferable.

板などとされている。 As shown in FIG. 2, the above-mentioned mounting plate 4 is provided with a large number of minute through holes 6...6 for water passage, and the load plate 5 placed thereon is It is made of, for example, an iron plate with a weight of about 20 to 30 kg/cm 2 that can compress and dewater the cement molded product placed on the mounting plate 4 .
尚、図中５Ａは荷重板５の吊り下げ支持用の把
手である。 In addition, 5A in the figure is a handle for suspending and supporting the load plate 5.
又、図示を省略するが、載置盤４下面にベルト
コンベヤ２と同様な吸水装置を付設しても良い。 Further, although not shown, a water absorption device similar to the belt conveyor 2 may be attached to the lower surface of the mounting plate 4.
次に、この考案のプレ脱水装置の作用について
説明する。 Next, the operation of the pre-dehydration device of this invention will be explained.
まず、セメントスラリーＢがコンベヤ２上に供
給されセメントスラリーＢが脱水されつつ移送さ
れる。 First, the cement slurry B is supplied onto the conveyor 2, and the cement slurry B is transferred while being dehydrated.
このとき、当初80％の含水率が吸引装置２Ａに
より徐々に脱水され、ベルトコンベヤ２末端で
は、ほぼ60％程度にまで脱水される。 At this time, the initial water content of 80% is gradually removed by the suction device 2A, and at the end of the belt conveyor 2, the water content is reduced to approximately 60%.
次いでベルトコンベヤ２末端においてセメント
スラリーＢは載置盤４上に移載され、次いでその
上に荷重板５が載置される。 Next, at the end of the belt conveyor 2, the cement slurry B is transferred onto the mounting plate 4, and then the load plate 5 is placed thereon.
そして、次のセメントスラリーB′がコンベヤ
末端に到着するまでセメントスラリーＢが荷重板

程度の含水率にまで脱水され、以後養生工程へと
移送されるのである。 Then, the cement slurry B is preliminarily dewatered by the load of the load plate 5 until the next cement slurry B' arrives at the end of the conveyor, and after this preparatory dewatering, the cement slurry B is sent to the press device 3, and the cement slurry B is fed to the press device 3 to produce a 100kg/ Finally 45% due to pressure around cm2
It is dehydrated to a certain level of moisture content and then transferred to the curing process.

引装置２Ａの脱水によりスランプ値は０とされる
ので、載置盤４への移載、並びに荷重板５の載置
による成形品の型くずれは全く生じない。 In the above, when the cement slurry B reaches the end of the belt conveyor 2, the slump value is set to 0 due to dewatering by the suction device 2A, so the cement slurry B is transferred to the loading plate 4 and the load plate 5 is The molded product does not lose its shape at all when placed.
この考案は以上のように構成されているので、

間当りの製造数量を増しても充分な脱水が行える
など種々の実用的効果を有する。 This idea is structured as above, so
Even if the length of the belt line of the belt conveyor is shortened, if the slump value of the cement slurry is approximately 0, the subsequent lack of dehydration will be sufficiently covered by preliminary dewatering using the mounting plate 4 and the load plate 5. ,
In addition, since the preliminary dewatering is carried out only by the weight of the load plate 5, no special equipment is required and it is easy to carry out. However, it has various practical effects such as sufficient dehydration even if the production quantity per unit time is increased.
