Grease trap. Patented in the German Empire on January 13, 1916.

Grease separators are already known which are used for steaming carcasses and the like find and cause an uninterrupted separation of the glue broth from the fat.

A special embodiment of such a fat separator consists of a vessel in which a second one is in the form of a bell or a hood Vessel is inserted; in the latter the emulsion of glue and fat comes from below

ίο her one, being the lighter fat in which inner vessel rising upwards, displacing the glue broth, so that it is finally below from the inner vessel into the outer, while the fat is pushed through a top on the inner vessel located tube is derived.

However, such grease traps have the previously known versions Deficiency that from the outside one can see the process of separating the fat from the glue broth difficult to see and track by leaving the inner vessel free in the outer vessel is arranged, and therefore both vessels through lateral tubes and outside taps are connected to this located trial, which device is only an imprecise Determination of the respective height of the fat-liquid level and the height of the fat layer allows.

According to the present invention, it is now possible to separate the fat from the Glue broth and the respective level of both liquid layers consistently from the outside to be able to observe, namely by the fact that the inner vessel is not on all sides as before is arranged standing freely in the outer vessel, i.e. a free one between the two vessels Space remains, but the vessel is divided into two rooms by a partition, of which one represents the fat container, the other the container for the glue broth. The jacket surface of the outer vessel thus partly forms the outer surface of the grease trap, partly that of the glue stock container. This makes it possible to participate in the common lateral surface a slot and a continuous from top to bottom To attach liquid level indicator.

However, it would not be advisable to simply create a flat septum for making it to choose of the two rooms; rather, it is expediently curved in such a way that it provides a large heating surface for the contents of the grease separator and this from that in the other Hot glue broth located in the compartment, as in the previous arrangements, if possible is highly heated.

The drawing shows several exemplary embodiments of the invention is a vertical section, Fig. 2 is a horizontal section; Figs. 3 and 4 show such of slightly different designs.

It is α according to FIGS. 1 and 2 the outer vessel, b the fat separator divided into this. According to FIG. 2, the partition t is a cylindrical body provided with a conical hood at the top, which has a longitudinal slot on the common outer side and is riveted with its edges to the circumference of the vessel α, which is also correspondingly slotted.

This slot opening has a body on the outside

per c, which is covered by the sight glass c ¹ . The glue broth containing the fat passes through the pipe g, coming from the upright digester, into the vessel b and rises in this, the fat collecting on top of the liquid layer. When δ is finally completely filled, the fat displaces the glue broth located below it more and ίο more downwards, where it is forced into the vessel α through the tube f located on the outside, which is provided with an adjusting valve there. This tube is initially kept closed. The glue broth now collects more and more in α , while the fat, the level of which ^{can be observed through the sight glass c 1} , is drained off at the top through the appropriately set tap d. The glue liquor can be pushed up through the pressure pipe i with the aid of steam or compressed air, entering through i; k is a vent cock. The show body cc ¹ does not have to go through completely from top to bottom, but can also consist of several shorter bodies in order not to weaken the vessel α so much through the continuous slot. The device can, however, also be expediently made according to FIG. 3, where the body or bodies c lie on the inside between α and δ, which arrangement facilitates the production of the connection of δ with α by means of riveting. One can also c all the way up to the apex let go of δ and the tap d side near the top of c Connect. According to the embodiment of FIG. 4, the fat separator is formed by a curved plate t , which embodiment is practically simpler; the more curved one chooses this plate, the more 'it approximates the embodiment according to FIG. 2 and offers a larger heating surface. However, grease traps are also known which contain them The glue stock container rest on one side on the inside and with the two parts of the outer surface that are in contact Take off the connector for the liquid level indicator located on the outside; in these known arrangements, however, forms the grease trap has a small, open-topped kettle, which is in the upper part of the glue broth kettle is freely suspended. This also contains a second vessel, which either has a kettle-like insert that is also open at the top represents, or this insert forms a bell that is open at the bottom and closed at the top. In In both cases the fat rising in the glue container flows over the upper edge of the open top insert; these arrangements therefore have the disadvantage that at the beginning, if the liquids have not yet separated, it is easy to add glue broth to the separating vessel especially if the liquid is very low in fat and the one Part of the fat layer, which is on the top side of the insert, not at all more can get into this, but has to be drained downwards. Also the arrangement nor an insert in the vessel intended as a grease trap, either Open at the top or at the bottom, as is the case with the arrangements mentioned, corrects this Not disadvantages, but only increases the unfavorable effect, such as the process of separation of the grease and its level can only be seen with difficulty or hardly at all from the outside. According to the present new facility on the other hand, all fat collects immediately from top to bottom without any residue fat separator that goes smoothly through the glue stock container; it can get the fat in this completely separated from the glue broth and discharged to the outside without the risk of the glue broth being carried along; it's just a ■ The only sharp dividing line between fat and glue broth exists and is this on the outside easily recognizable at any liquid level, so that the device is not permanent requires careful observation. ■ Patent claim: Fat separator in which one vessel is arranged inside another and the emulsion of the liquids to be separated is introduced into the inner vessel so that the lighter component (the fat) rises in this and the other liquid (the glue broth) rises down and is pushed into the other vessel, characterized in that within the outer vessel (a) there is arranged a plate (if) designed as a partition, possibly strongly curved, which together with part of the casing of the vessel (a) forms the fat separating space (δ) forms, which is connected to the glue stock vessel (a) below by a detachable pipe (ef) , and the outer, common jacket part is provided with a slot for attaching a device (cc ¹ ) reaching from top to bottom for monitoring the liquid level.
