管路の閉塞事故を解消できるようになる。(Operation) As described above, in the pressure crystallizer according to the present invention, the raw material supply port is formed in the inner peripheral wall of the pressure-resistant cylindrical body on the piston entrance side, and further, the inner peripheral wall and the outer peripheral portion of the piston are respectively provided. A cylindrical seal member is provided which is fitted and which moves forward and backward independently of the piston member to close or open the supply port. Therefore, the inner wall side opening of the raw material supply port (hereinafter referred to as the supply port) can be closed by the tubular seal member. In this closed state, high pressure is applied to the pressure resistant cylinder due to crystallization and filtration / squeezing. However, since this high pressure does not act on the supply port, the cross-sectional area of the supply port should be sufficiently large. it can. Therefore, the raw material supply time can be shortened. Further, when the raw material is supplied in the form of a slurry, it becomes possible to eliminate the blockage accident of the raw material supply pipe which is often experienced in the conventional apparatus.

に、ケーキＣの取出しができるようになる。Further, the pressure-resistant cylindrical body, the lid and the piston are arranged (horizontal type) so that their respective axes are in the horizontal direction. Further, at least one of the pressure resistant cylinder and the lid is movable in the axial direction of the pressure resistant cylinder, and the piston is movable in the pressure resistant cylinder. Therefore, after the completion of filtration and squeezing, the pressure resistant cylinder can be horizontally retracted from the lid, or the lid, the cake C and the piston can be horizontally retracted from the pressure resistant cylinder. By doing so, the cake C can be sandwiched between the lid and the piston, and the pressure-resistant cylindrical body does not exist around the cake C. Next, if the piston is retracted, the cake C falls by its own weight (that is, the cake C is taken out). As described above, the cake C can be taken out by advancing and retracting at least one of the pressure resistant cylinder and the lid and by advancing and retracting the piston, and without using the chute (8) and pusher (7). Therefore, the cake C can be taken out easily in a short time.

Ｃの純度低下の問題点が解消される。In addition, since the pressure crystallizer according to the present invention is of the horizontal type as described above, the residual liquid in the pressure-resistant cylinder does not drop in the cake C removal step, and therefore the problem of deterioration of the purity of the cake C due to the residual liquid occurs. The points are eliminated.
更に、本発明に係る圧力晶析装置は、上記の如く、横型

易になる。Further, since the pressure crystallizer according to the present invention is of the horizontal type as described above, there is no height restriction, and the forward / backward stroke of the pressure resistant cylinder or the piston can be made sufficiently long. As a result, the pressure-resistant cylindrical body and the piston can be separated from each other, so that the filter and the like in the pressure-resistant cylindrical body can be easily cleaned and replaced. Further, since it is horizontal, the height (height) of the device can be reduced, which further facilitates cleaning of the pressure resistant cylinder.
尚、耐圧性筒体および蓋体の少なくとも一方が耐圧性筒
体の軸心方向に進退可能であるので、両方とも進退可能
にしてもよいし、またいずれか一方だけを進退可能な構
成としてもよい。これらの中、何れの構成とするかは、
設置現場の状況に応じて選定すればよい。Since at least one of the pressure resistant cylinder and the lid can move back and forth in the axial direction of the pressure resistant cylinder, both of them can move forward or backward, or only one of them can move forward or backward. Good. Which of these configurations should be used
It may be selected according to the situation of the installation site.
原料（スラリ状液体）の注入方法に関し、供給口の断面
積を充分大きくできるので、原料の自重で注入してもよ
いし、或いは加圧手段を用いて注入してもよい。Regarding the method of injecting the raw material (slurry liquid), since the cross-sectional area of the supply port can be made sufficiently large, the injection may be performed by the weight of the raw material, or by using a pressurizing means.
耐圧性筒体の内面形状に関し、耐圧性の観点から円形が
最も望ましいが、場合によっては楕円形でもよく、また
六角形などの多角形状とすることも可能である。Regarding the shape of the inner surface of the pressure resistant cylinder, a circular shape is most preferable from the viewpoint of pressure resistance, but in some cases it may be an elliptical shape or a polygonal shape such as a hexagonal shape.

制限がなく、公知のパッキンを適用できるものである。The seal member closes the inner wall side opening of the supply port when it is fitted to the inner peripheral wall of the pressure resistant cylinder. In order to fulfill this function, a seal packing may be provided between the inner wall side opening of the supply port and the pressure resistant cylinder in which high pressure is applied. The shape and structure of this packing are not particularly limited, and known packing can be applied.

た。Next, the cake C is carried out, the piston (4) is retracted to the right in the drawing, and the pressure resistant cylinder (1) is also removed.
Was advanced to the left in the drawing, and its left end was fitted to the lid (3). By this operation, the pressure crystallizer is in the state before the raw material injection described in FIG. After that, the raw material was injected into the pressure-resistant cylindrical body (1), pressure crystallization, filtration and compression, and cake C was dropped and carried out by the same procedure as described above.

As a result, compared with the case where pressure crystallization was performed by the conventional apparatus, the time required for the repeated operation cycle was greatly reduced to several percent to several tens percent. Moreover, the product purity was improved. Further, although the inside of the pressure resistant cylinder was inspected during the repetition of the above operation, the inspection was extremely easy.

なる。(Effect of the Invention) According to the pressure crystallizer according to the present invention, the raw material supply time can be shortened, and since the cake C can be taken out easily in a short time, the time required for the repeated operation cycle can be reduced. It can be greatly shortened and the productivity can be made extremely excellent. Further, since the problem of the product purity lowering due to the residual liquid in the pressure resistant cylinder is solved, the product purity can be improved. Furthermore, maintenance and inspection of the pressure resistant cylinder can be easily performed.
上記に加えて、原料をスラリ状で供給する場合に、従来
