Definitions

• the invention discloses a method for emptying containers with an integrated cleaning, pumping and spraying device.
• German Offenlegungsschrift DE 2401 764 A1 discloses a system for storing and treating wine or fruit juice.
• the plant is characterized by the fact that the storage tanks on the upper side have openings over which arranged on a crane or a monorail machines or apparatuses by means of this or these movable and through the openings vertically from above into the tank cavities telescopically and / or by Wire cables are retractable. With these machines and apparatus, procedural operations can be carried out within the empty and full tanks.
• the patent DE 102 56 560 B4 discloses a cleaning device for large containers.
• spray nozzles for cleaning fluids and rotating brushes are known. It is obvious to apply these principles also for the internal cleaning of large containers. But these containers are mainly accessible only through small openings. Entering and using cleaning devices by persons inside the container endangers them. There have therefore been developed various cleaning devices that are to be operated from the outside.
• the container in the cleaning area about one of the container axes are rotatable by 90 degrees, wherein the rotational movement by acting on the container fluid pressure of at least one high-pressure cleaning liquid nozzle under application of the container a stop takes place. Due to the rotational movement of the containers, it is possible to clean them thoroughly from all sides by means of the water pressure applied vertically to the side surface.
• the cleaning nozzle thus fulfills a double effect, namely on the one hand the cleaning of the container and on the other hand, the implementation of the rotational movement. Due to the Device according to the invention, the linear shape of the car wash is maintained and the construction proves to be extremely space-saving.
• a plurality of nozzles may be provided, which act on the container from two opposite sides with the cleaning liquid or the water. This simultaneously cleans two sides of the container, thus saving cleaning time.
• the linear shape of the cleaning device is retained.
• several nozzles can be switched on for thorough cleaning.
• the invention has for its object to provide a method for economical and reliable emptying and cleaning of containers.
• a method for emptying and cleaning containers is disclosed, wherein the following steps are performed in carrying out the method.
• the device according to the invention is placed on a container. Subsequently, a pump is lowered by means of a lifting device in the container. During lowering of the pump, the product is pumped out of the container. During the lowering and pumping of the product, a fluid is injected from a distribution device into the container. Preferably, this fluid is sprayed against the inner wall of the container. However, it is also possible to arrange the outlet openings so that the fluid is sprayed to the container lid, the container bottom and / or for holding and thus to the pump. Such a nozzle arrangement would also clean all components of the device which have come into contact with material from the container.
• the introduced fluid is pumped out of the container together with the product.
• the device according to the invention also completely cleans the container during complete emptying. If the container is provided with an inliner, this is also completely cleaned and emptied.
• the device of the present invention is capable of minimizing this residual amount Residual amount of product in the container again reduced, so that if possible only fluid remains in the container.
• the fact that the inliner is supported by a fixing system, which is located on the container lid, the inliner can be removed after cleaning and emptying from the container together with the device. All you have to do is remove the container lid together with the lifting device and the pump from the container.
• the product is pumped out of the container after lowering the pump.
• the cleaning of the container may take place during or immediately after the final unloading operation. If a fluid is used for cleaning, which also applies to the dilution of the material from the container, in the further processing, application, so this can be introduced during emptying. By the exact adjustment of the amount of fluid, a desired mixing ratio of material and fluid can be adjusted.
• the method according to the invention could be carried out with a device for complete and economical emptying and cleaning of containers, which has the following features.
• the device consists of a lifting device with a pump and a support frame. At least one distribution device for fluids is arranged on the lifting device, this at least one distribution device being fastened to the lifting device.
• at least one distribution device is firmly connected to the carrier frame.
• only the pump in the container is opened and shut down for pumping and cleaning, but the distribution device remains stationary.
• the distribution device is laterally spaced from the container. The distance between the distribution device and the inner wall of the container is ensured by spacers. Also, the distance between the distribution device and an inliner introduced into the container is ensured by these spacers.
• the distribution device has the same shape as the inner wall of the container.
• the distribution device is provided at its top and / or on its underside with outlet openings.
• the outlet openings are designed in a preferred embodiment as nozzles.
• the distribution device is a so-called spray ring. It is clear to the person skilled in the art that the spray ring does not necessarily have to be round. Depending on the geometry of the container, the spray ring can also be made oval or square.
• the nozzles described above may be special nozzle arrangements or simple holes located in the distribution device. Depending on the embodiment, it is possible to supply the outlet openings all with fluid via a supply line or to connect each outlet opening separately and thus to supply fluid. In the supply of each outlet opening via a separate supply line, it would also be conceivable to use different fluids.
• the distribution device is fixed or releasably connected to the lifting device.
• the lifting device is provided with a first distribution device and with a second distribution device.
• the first distribution device is fixedly attached to the lifting unit below a container lid.
• the second distribution device is arranged at a lower end of the lifting device. The amount of fluid dispensed from the first distribution device and the second distribution device into the container is adjustable.
• the container lid is provided with holders for fixing the inliner. With the help of these brackets it is also possible to remove the inliner from the container.
• the inliner may be a bag made of foil or a solid body made of a corresponding material which is introduced into the container.
• the lower end of the lifting device is designed as an intake.
• a pump is arranged, with which the emptying of the container is performed.
• the pump is designed as an eccentric screw pump.
• Fig. 1 shows a device according to the invention.
• Fig. 2 shows a preferred embodiment of the device according to the invention.
• Fig. 3 shows the structure of a distribution device according to the invention.
• FIG. 1 shows a device 10 according to the invention.
• the device 10 consists of a lifting device 14, in which a pump 16 is integrated.
• the device 10 is placed on a container 12 which is closed by a container lid 30.
• FIG. 2 shows a preferred embodiment of the device 10 according to the invention.
• the device 10 consists of a lifting device 14 with an integrated pump 16.
