〔産業上の利用分野〕
本考案は、無端帯状ろ布を重力脱水部から強制

を設けた脱水機に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides an endless band-shaped filter cloth that is rotatably provided from a gravity dewatering section to a forced dewatering section, and the filter cloth is provided rotatably from the gravity dewatering section to the forced dewatering section. This invention relates to a dehydrator equipped with a roll that acts on a cake on a filter cloth so that the thickness of the cake becomes constant.
従来、ロールにより滞留しているケーキは、な
んら特別な処理を受けずに、自然とロールとろ布
間に引き込まれるように構成していた。
Conventionally, the structure was such that the cake retained by the rolls was naturally drawn between the rolls and the filter cloth without any special treatment.
しかし、重力脱水部からろ布に貼りついて送ら

とんど脱水処理されず、脱水性能向上の面からよ
り一層の改良の余地があつた。
However, the cake stuck to the filter cloth from the gravity dewatering section passes through the rolls, and the cake is disturbed by the rotation of the filter cloth and rolls. However, the cake stuck to the filter cloth is in a state where it is difficult for moisture to pass through, so even if the cake is squeezed between the roll and the filter cloth, it is hardly dehydrated. There was room for further improvement in terms of improved dewatering performance.
本考案の目的は、ロールによる滞留で水分が抜
けやすくなつたケーキを、重力脱水やロールとろ
布による挾圧脱水によつて十分に脱水処理できる
ようにする点にある。 The purpose of the present invention is to make it possible to sufficiently dehydrate a cake whose moisture easily comes out due to retention in the rolls by gravity dehydration or clamping pressure dehydration using the rolls and filter cloth.
本考案の特徴構成は、重力脱水部からのろ布上

あり、その作用効果は次の通りである。
The characteristic configuration of the present invention is that a member for scraping back the cake staying on the filter cloth from the gravity dewatering section to the gravity dewatering section by means of a roll for making the thickness of the cake on the filter cloth constant is provided by a large number of scrapers. The return action portions are arranged in a line in the width direction of the filter cloth, and a drive device is provided for reciprocating the scraping action portions in the longitudinal direction of the filter cloth and approaching the filter cloth during scraping back. , its functions and effects are as follows.
つまり、滞留時にろ布やロールで撹乱されて水
分が抜けやすくなつたケーキを重力脱水部側に掻
戻すと、掻戻し作用部がろ布に接近して掻戻し動

In other words, when a cake that has been disturbed by the filter cloth or rolls during retention and whose moisture is easily removed is scraped back to the gravity dehydration section, the scraping-back action section approaches the filter cloth and performs the scraping operation, so it is attached to the filter cloth. A portion of the cake that was sent along with the filter was scraped off, and drainage points where dehydration easily occurs through the filter cloth were formed in a row in the width direction of the filter cloth, and the cake that had accumulated was scraped off near the drainage point. Since the moisture in the cake is easily drained by being placed and retained, the moisture in the cake is sufficiently removed from the draining point by gravity and the clamping pressure between the filter cloth and the roll. Furthermore, the cake stuck to the filter cloth is partially turned over and a drainage point is formed nearby, so that water is sufficiently dehydrated.
その結果、ロールから強制脱水部に送るケーキ
の含水率を従来に比して十分に低くでき、強制脱
水部においてケーキを、そのはみだし等による制

As a result, the moisture content of the cake sent from the rolls to the forced dehydration section can be sufficiently lowered compared to the conventional method, and the cake can be strongly squeezed and pressure dehydrated in the forced dehydration section with fewer restrictions due to protrusion, resulting in an extremely low water content. A dehydrated cake with a high water content can now be obtained.
