構成される。DETAILED DESCRIPTION OF THE INVENTION The present invention uses a moving endless filter cloth or the like, the sludge is fed onto the filter cloth at specific feeding points, and the solid cake is moved in the direction of rotation of the filter. It is constructed as a sequential operation rover technique that will be removed from political trading in a later section.

とは、極めて重要である。連続操作の公知のr過技法に
おける一般的な1つの欠点は、フィルタ布の急速な閉塞
であり、これは、政商に埋込まれる粒子によって生じる
。この理由により、フィルタ布は、工程中、連続的に洗
滌されねばならず、該洗滌は、所謂逆流法で最も効果的
に実施可能である。To obtain high efficiency, it is extremely important that the filter cloth, screen or other media remain as constant as possible throughout the process. One common drawback of known filtration techniques of continuous operation is rapid blockage of the filter cloth, which is caused by particles becoming embedded in the filter cloth. For this reason, the filter cloth must be washed continuously during the process, which washing can be carried out most effectively by the so-called backflow method.
本発明の目的は、フィルタ布またはその他のフィルタ媒

自動的に布を清掃することを可能にし、このため、特別
な清掃操作な必要としない。It is an object of the present invention to provide a continuously operating filtering technique in which filter cloths or other filter media are cleaned by the use of backflow methods in a simpler and more effective manner than previously. A feature of the invention is that the sludge is removed twice on different sides of the fabric.
Particles which are fed onto the fabric at points and which the removal unit fails to remove are therefore washed away by the liquid passing through the fabric. In other words, the invention makes it possible to automatically clean the fabric during the process, so that no special cleaning operations are required.
従って、フィルタ布の両側を使用する着想は。Hence the idea of using both sides of the filter cloth.
公知の方法である。しかしながら、該濾過工程は。This is a known method. However, the filtration step.
連続操作を包含せず、また、関連する装置は、工程自体
によって充分な清掃を与え°る様に構成されていない。It does not involve continuous operation, and the associated equipment is not configured to provide adequate cleaning by the process itself.
従って、該装置は、濾過の段階の間で布の両側へ洗浄剤

ある。A feature in another application of the invention is that pressure is applied to the sludge between the feeding point and the removal point by rollers that press the filter cloth into a bag-like shape. In this way, sludge is prevented from escaping from the sides, which is particularly important if the internal friction of the solid particles is low.

ラッジに圧力を加えるローラを備えてもよい。A device constructed according to the invention may include a compression belt that moves in the same direction as the fabric between the feeding unit and the removal unit, and that is installed between the feeding unit and the removal unit. A roller may be provided to apply pressure to the sludge by compressing it into the cloth T-bag-like shape.
本発明は、その実施例に関し添付図面tt診照して下記

通過する。It is followed by a removal unit 5 which removes the solid cake 6 from the fabric 1 with a scraper 7. The sludge is compacted between the feed unit and the removal unit by means of a suppression belt 8 or rollers 9 moving in the same direction as the fabric 1, and additional support is provided by a support belt 10 moving under the fabric. Given. When the sludge is compressed, the liquid passes through the filter cloth 1 and the support belt 10, as shown by arrow 11 in FIG.

体物質を除去する。The essential point of the filtration process shown in FIGS. 1 and 2 is that the sludge 3 is fed by a feeding unit 2 to different sides of the fabric 1. In this process, the cloth 1 is separated from the sludge 3.
The liquid passing through removes any solid material embedded in the cloth during the preceding stages of filtration.
従って、該工程は、布の逆流洗浄を提供し、別個の洗浄
ユニットを必要としない。The process thus provides backwashing of the fabric and does not require a separate washing unit.

保持される。The filtration process shown in FIG. 6 to FIG.
It differs from those shown in FIGS. 1 and 2 in that the net-like belt and the core support are pressed into a bag-like shape between the feeding unit and the removal unit. The pressing is accomplished by a roller 12 which simultaneously separates the liquid from the solid material, as indicated by the arrow 11 in FIGS. 6-6. Backwashing of the fabric is carried out as described above, and this process is particularly suitable for sludges with low internal friction, which are retained in the fabric during the compression stage in a temple-like manner.
