Definitions
- the invention relates to a separating device and a method for producing a separating device.
- Separating devices are necessary in many canteen kitchens, gas stations and other businesses to separate grease from (waste) water before the cleaned water gets into the sewage system.
- Separating devices are known from the prior art, which, particularly in the case of an underground application, comprise a plurality of structures. For example, a first structure is often provided for separating fat from (waste) water, a second structure for sampling the cleaned water and a third structure for a lifting plant or pumping station. Separating devices of this type have an increased space requirement and increased production and assembly costs.
- separating devices have been developed which enable fat separation, sampling and the arrangement of a lifting station in a single structure. Separating devices of this type often have a concrete shaft as the base body and separate components for dividing the interior of the concrete shaft. However, the production of the basic structure of the separating device is complex here.
- US Pat. No. 9,932,247 B1 discloses a grease separating device which has a tank-shaped base body and a horizontal baffle made of plastic.
- the baffle serves to calm the flow of the inflowing waste water and forms a separate component that is installed in the base body. There is thus an increased installation effort.
- a hydraulic tank made of plastic is known from WO 01/83307 A1, which is provided for use in a hydraulic system of machines, for example.
- the hydraulic tank has a baffle wall, which is designed as a protrusion in the tank housing and protrudes halfway into the interior of the tank housing.
- the baffle is formed in one piece with the tank housing.
- the baffle serves to homogenize the flow in the hydraulic tank.
- the invention is based on the object of specifying a separating device which has a compact design and can be produced easily and inexpensively. Furthermore, the invention is based on the object of specifying a method for producing a separating device.
- this object is achieved with regard to the separating device by the subject matter of claim 1.
- the above object is achieved by the subject matter of claim 15 or 16, respectively.
- the object is achieved by a separating device with at least one inlet for a contaminated liquid, in particular greasy water, and a receiving body which has at least a first chamber for receiving the contaminated liquid and at least a second chamber for receiving the cleaned liquid.
- the inlet opens into the first chamber.
- the first chamber is fluidly connected to the second chamber for transferring the cleaned liquid.
- the two chambers are separated from one another by at least one partition.
- the partition wall is formed integrally with the receiving body.
- the separating device preferably serves to separate a liquid mixture, in particular greasy (waste) water.
- the separating device is preferably used to separate fats from water.
- the separating device can generally be referred to as a fat separating device.
- the contaminated liquid is referred to as greasy (waste) water and the cleaned liquid as cleaned water.
- Fatty water is a mixture of liquids that Has water content and at least one fat content.
- Purified water means water from which the fat content has been separated.
- the invention is not limited to the separation of fat from water. It is possible that the separating device can be used to separate light liquids, such as oil, petrol and/or diesel, from a liquid, in particular water. Other areas of application are possible.
- the receiving body has the first chamber and the second chamber, which are separated from each other by the partition wall.
- the receiving body is designed as a hollow body, with the dividing wall dividing an interior space of the receiving body into the first chamber and the second chamber.
- the first chamber is used to hold the water containing fat and to separate the fat from the water.
- the greasy water flows through the inlet into the first chamber of the receiving body.
- the fat is separated from the water in the first chamber.
- the fat settles on the water surface in the first chamber.
- the portion of fat contained in the water containing fat rises to the surface of the water in the first chamber and forms a layer of fat that floats on the portion of water below.
- the water content corresponds to the cleaned liquid, which is then transferred to the second chamber.
- the two chambers are fluidly connected to one another.
- the second chamber is used to receive the purified water from the first chamber. Furthermore, the second chamber serves to collect the purified water.
- the collected water can be discharged from the second chamber by at least one conveying device, in particular a liquor system.
- the conveying device can be arranged in the second chamber.
- the delivery device can be a pumping station, for example, which pumps the cleaned water out of the second chamber during operation.
- the second chamber is used for sampling the cleaned water.
- the separating device according to the invention has a compact design due to the described chamber structure of the receiving body, which allows the separating of fat from water, a sampling of the cleaned water as well as the integration of a conveyor device for discharging the cleaned water into a waste water system in a small space.
- the partition separates the two chambers from each other.
- the partition wall is arranged between the two chambers.
- the partition wall is designed in such a way that, during operation, fat separated from the fat-containing water is held in the first chamber and the cleaned water can flow into the second chamber.
- the dividing wall thus separates the first chamber from the second chamber, which dividing wall, in use, prevents the flow of separated fat from the first chamber into the second chamber and at the same time allows a flow of purified water from the first chamber into the second chamber.
