Description

Evakuierbare Nutsche mit Deckel, der in einen Flüssigkeitsverschluß taucht.Evacuable suction filter with a lid that fits into a liquid seal dives.

Zusatz zum Patent 328877. Addendum to patent 328877.

In der Hauptpatentschrift 328877 ist eine evakuierbare Nutsche beschrieben, bei welcher der bewegliche Nutschendeckel mit seinem Boden bei der Senkung auf das abzunutschende Gut drückt, während zur Herstellung eines luftdichten Verschlusses die äußeren Seitenwände des Deckels in einen Flüssigkeitsverschluß tauchen. Der. Boden der Nutsche kann durchlässig sein, um Dampf u. dgl. in das abzunutschende Gut zu führen. In the main patent specification 328877 an evacuable suction filter is described, in which the movable groove cover with its bottom when lowering onto the Presses the product to be sucked off while producing an airtight seal immerse the outer side walls of the lid in a liquid seal. Of the. The bottom of the suction filter can be permeable to allow steam and the like to enter the suction pipe Good to lead.

Während nach dem Hauptpatent lediglich der Boden der Nutsche zum Filtrieren benutzt wird, sind nach der vorliegenden Erfindung die Seitenwände der Nutsche derartig ausgestaltet, daß auch die Seitenwände zur Filtration dienen. Außerdem ist der Boden derartig eingerichtet, daß er nicht nur durch eine horizontale Fläche filtrieren wird, sondern daß eine größere Fläche für die Filtration ausgenutzt werden kann. While according to the main patent only the bottom of the nutsche Filtration is used, according to the present invention, the side walls of the Nutsche designed in such a way that the side walls are also used for filtration. aside from that the floor is set up in such a way that it is not only covered by a horizontal surface will filter, but that a larger area can be used for the filtration can.

Die Neuerung ist in den Fig. I,2 und 3 der beiliegenden Zeichnung im senkrechten Schnitt beispielsweise veranschaulicht. The innovation is in Figs. I, 2 and 3 of the accompanying drawings illustrated in vertical section, for example.

In der Fig. I stellen die schraffierten Flächen bt, b2 die Gesamtfüllung der Nutsche dar. Die Fläche bl zeigt beispielsweise den Raum, um welchen das gesamte Nutschgut während der Filtration verringert wird, während die Fläche b2 den Rückstand anzeigt, welcher in der Nutsche schließlich verbleibt. In FIG. I, the hatched areas bt, b2 represent the total filling the Nutsche. The area bl shows, for example, the space around which the entire Filter material is reduced during the filtration, while the area b2 the residue indicates which one will ultimately remain in the nutsch.

Der Boden a ist nach. oben geneigt, hochgezogen, wie bei a1 gezeigt, und besitzt Durchlochungen, damit hierdurch Flüssigkeit abfließt. Bei der Einrichtung des Hauptpatents sind die Seitenwandungen vertikal und schließen mit den senkrechten Wandungen der Nutsche ab. Durch die neue Gestaltung der Seitenwände nach der vorliegenden Erfindung wird die Nutschfläche erheblich vermehrt, beispielsweise um etwa 50 Prozent.The bottom a is after. tilted up, pulled up, as shown at a1, and has perforations so that liquid can flow through it. When setting up of the main patent, the side walls are vertical and close with the vertical ones Walls of the nutsche. Due to the new design of the side walls according to the present Invention, the groove area is increased considerably, for example by about 50 percent.

Zur Steigerung der Filterwirkung wird auch der Boden a vorteilhaft in der Mitte nach der Linie a2 hochgezogen (Fig. 2), wodurch eine weitere Vermehrtmg der wirksamen Filterfläche erreicht wird. To increase the filter effect, the bottom a is also advantageous pulled up in the middle after the line a2 (Fig. 2), whereby a further increase the effective filter area is achieved.

Man kann auch den Nutschendeckel zur Erhöhung der Leistungsfähigkeit der Nutsche heranziehen, indem man den Boden d vorteilhaft in der Mitte nach unten senkt und eine Vertiefung d1 anbringt (Fig. 3). Die Wandungen dieser Vertiefung sind dann mit Durchlochungen versehen. You can also use the groove cover to increase performance the nutsche draw by pulling the bottom d advantageous down the middle lowers and makes a recess d1 (Fig. 3). The walls of this recess are then provided with perforations.

Mit dem Fortschreiten des Nutschverfahrens senkt sich der mit Flüssigkeitsverschluß versehene Deckel c mit dem Zusammendrücken des Nutschgutes, beispielsweise bis zu der punktierten Linie, welche die schraffierten Flächen b1 und b, trennt. Es dringt also der mit der Vertiefung versehene Boden d (Fig. 3) dauernd zuerst in den schraffierten Raum bl und dann in den schraffierten Raum b2. Hierdurch wird ermöglicht, daß beim Nachbehandeln des Nutschgutes mit Gasen, Dampf oder Flüssigkeiten der in der Nutsche verbliebene Kern b2 wirksam behandelt wird. As the suction process progresses, that with the liquid seal decreases provided lid c with the compression of the suction material, for example up to the dotted line separating the hatched areas b1 and b. It penetrates So the bottom d provided with the depression (Fig. 3) is always first in the hatched Room bl and then into the hatched room b2. This enables that when post-treating the filter material with gases, steam or liquids in the Nutsche remaining core b2 is effectively treated.

Der Boden a der Nutsche (Fig. I) kann mit einer Untenentleerung s derart versehen sein, daß nach Hebung des Deckels t für diese Untenentleerung der Inhalt b2 der Nutsche durch den Untenablaß s entfernt werden kann. The bottom a of the nutsche (Fig. I) can s with a bottom emptying be provided in such a way that after lifting the lid t for this bottom emptying of the Content b2 of the suction filter can be removed through the bottom drain s.

Der Deckel c der Nutsche kann eine mit Absperrhahnx versehene, durch den Deckelraum sich erstreckende Röhre o. dgl. y erhalten, welche gestattet, die Nutsche auch bei geschlossenem Deckel zu füllen oder bei vorgeschrittenem Nutschprozeß neues Filtergut einzubringen. Diese Möglichkeit ist von besonderer Wichtigkeit, wenn es sich um leicht verdunstende Flüssigkeiten handelt oder die Entwicklung giftiger Gase eintreten kann. The cover c of the nutsche can be provided with a shut-off valve the cover space extending tube o. The like. Y received, which allows the The suction filter can also be filled with the lid closed or when the suction process is advanced to bring in new filter material. This possibility is of particular importance if it is a question of easily evaporating liquids or the development of toxic ones Gases can enter.

Claims

According to the main patent, the cover of the nutsche is with a single one Lateral approach provided, which is immersed in liquid, creating a secure closure should be achieved. Especially when working with a high vacuum is this type of closure is not sufficient. According to the present invention the lid is not provided with a single vertical wall g, which is in a single liquid closure h is immersed, rather the lid, as shown in FIG and Fig. 4 illustrate several side walls (e.g. 3) which in turn again immerse in three liquid containers. The lid can be -direction, such as pawls w and racks v, are held (Fig.). the Latches w can also be directed upwards and downwards, so that the cover depending on the purpose can be prevented from going up or down. This retention Certain layers are used especially in the case of treating the suction material with Washing liquids or gases under pressure.

In this case, the shut-off liquid in the multi-way closure is the achieve the required degree. One can take advantage of this liquid seal work once only in a vacuum and then in a known manner in a vacuum with pressure. This results in a significant increase in the suction effect. In the upper part 1 of the suction filter, for example, there is an evacuation of about S14 atmospheres while In the upper part of the nutsch in the cover c there is an overpressure of S14 atmospheres can. In this way, the rest of the suction material, which is between the two Areas a and d is clamped, just like you can handle in a filter press. One is, for example, with the nutsche that with the present liquid seal is provided, can perform the following tasks.

The nutsche is with the lid open or closed, like in FIG. I, with the lid held up, filled, in the latter case through the tube y; if necessary a refilling of the goods is carried out through this pipe - the nutsche can either be emptied by shoveling with the lid open, as has been done before, or using the bottom drain S. The use of evacuated and atmospheric or pressure higher than that of the atmosphere can go on in such a way that there is no air in the lower part of the nutsche 1 and in the upper part of the nutsche c, and that in another case in the lower part of the nutsche 1 air void prevails and in Upper part of the nutsche c lower vacuum or atmospheric pressure. But it can Atmospheric or higher pressure also prevail in the lower part of the nutsche I and in the upper part of the nutsche c air empty, if the subsequent vacuum and pressure lines be connected accordingly in a manner not shown here. The Nutsche can be heated, cooled, the omissions and steam treatments are done like until now.

The height of the liquid seal M is determined from the height the vacuum used and the specific weight of the used coming shut-off liquid. Liquids are advantageously used as such of high specific weight, e.g. B. Solutions of calcium chloride or magnesium chloride, so that the height ht does not exceed a practically permissible level.
