Definitions
- the invention relates to a system for emptying a container filled with a flowable medium.
- flowable medium here means a product which no longer flows when it is only exposed to the gravitational force.
- the system of the present invention is intended to be particularly suitable for use with such high viscosity media.
- DE 352 172 A shows a container for lacquers, paints, etc., which can be sealed airtight
- DE 362 557 A shows a syringe for medical purposes with a screw connection between the piston rod guide and the glass cylinder.
- DE 37 24 277 C2 shows a device for mixing and / or drying of pourable materials, wherein a lifting device is provided, with which a lid mounted on this can be extended.
- the closest document DE 30 25 241 C2 shows a system for emptying a container filled with a flowable medium, comprising: a container in which a homogenization of product mass takes place by mixing; a discharge device, which is formed wall-wise with an inner wall of the container and after the completion of the mixing is introduced into the container and a device for pressurizing the Discharge device, so that this presses the homogenized / mixed product mass toward the bottom of the container down where the homogenized / mixed product mass is discharged through an outlet opening of the container.
- the discharge device is designed form flexible.
- the system according to the invention for emptying a container filled with a flowable medium has in particular the following:
- a discharge device which is formed in a wall-like manner with an inner wall of the container and is introduced into the container after the completion of the mixing;
- the system for emptying a filled container with a flowable medium further comprises a first lifting device mounted on a first lid with flanged mixer, with which mixing for homogenizing the product mass takes place, the first lid with flanged mixing after mixing by means of the first lifting device is fully extended.
- the system for emptying a container filled with a flowable medium as a means for pressurizing the
- Discharge device further comprises a second lifting device on a second lifting device away from the container and rotatably mounted to the container second lid, which is pivoted after inserting the discharge device to the container and the container pressure-tight manner, after which the discharge is pressurized in the container.
- the discharge device is preferably a disc or a cylinder which is made of pressure-resistant material by manufacturing with the highest precision on the inner diameter of the container wall-mounted with the inner wall of the container.
- the disk or cylinder can be placed as a discharge device on the homogenized / mixed product mass.
- the discharge device is preferably flexible in shape and adapts ideally to the bottom geometry of the container at the end of the discharge.
- LDPE low-density polyethylene
- PTFE polytetrafluoroethylene
- the product yield can be further increased in a simple manner compared to the discharge rate achievable with a system according to the prior art.
- Fig. 1 shows a system according to the invention for emptying a container filled with a flowable medium
- Fig. 2 is a plan view of a discharge device according to the present invention.
- Fig. 3 shows a side view of a discharge device according to the present invention.
- FIG. 1 shows a system according to the invention for emptying a container filled with a flowable medium.
- the system has a container 3, in which a homogenization of highly viscous / flowable product mass takes place.
- the system is here shown in a state of mixing in which a first lid 1 closes the container.
- the first cover is mounted on a first lifting device 11.
- On the first cover 1 is a on this flanged mixing plant provided, with which a mixing to homogenize the product mass takes place.
- the first cover 1 with flanged mixing unit is fully extended after mixing by means of the first lifting device 11.
- FIG. 1 also shows a second cover 2 mounted on a second lifting device 21 with pivoting function away from the container 3 and pivotable relative to the container 3, which is turned away from the container 3 during the mixing shown in FIG.
- a discharge device 4 shown in Figures 2 and 3 is introduced into the container 3 and the homogenized / mixed Product mass laid.
- the discharge device 4 is formed with the inner wall of the container 3 wall-mounted. It is preferably formed as a disc or a cylinder, as shown in Figure 2 in a plan view in the case of a cylindrical container 3 with an annular inner diameter. It is made of pressure-resistant material by manufacturing with highest precision on the inner diameter of the container 3 wall-shaped with the inner wall of the container 3.
- the discharge device 4 is, as it is indicated in the side view of Figure 3, also preferably flexible in shape and so adapts to the end of the discharge ideally to the bottom geometry of the container 3. Due to the shape-flexible design of the discharge device, which is preferably made of polyethylene (LDPE (low-density polyethylene)), polytetrafluoroethylene (PTFE) or similar materials, thus provided for a further reduction in residual amount remaining in the container homogenized / mixed product mass.
- LDPE low-density polyethylene
- PTFE polytetrafluoroethylene
- the discharge device 4 After the discharge device 4 is placed in the container 3 and the homogenized / mixed product mass, it is by means of a device. 5 pressurized to pressurize so that it pushes down the homogenized / mixed product mass towards the bottom of the container 3 where the homogenized / mixed product mass is discharged through an opened outlet valve 31 of the container 3.
- FIG. 1 For the pressurization of the discharge device 4 is shown in Figure 1 on a second lifting device 21 with pivoting away from the container 3 and hinfbar mounted to the container 2 second cover 2 is provided, which is pivoted to the container 3 after inserting the discharge device 4 and the Container 3 pressure-tight closes, after which then the discharge device 4 is pressurized in the container 3 with pressure.
- the first lid 1 with flange-mounted mixing mechanism is thus removed from the container 3 after a mixing of product mass.
- the discharge device 4 which is wall-going with the inner wall of the container 3, placed in the open and unpressurized container 3 and on the product mass.
- the discharge device 4 is pressurized.
- the second cover 2 is pivoted in the direction of the container opening in order to then close the container.
- the discharge device 4, which is formed in particular as a disc or cylinder made of pressure-resistant material pressurized and thereby pressed in the direction of the bottom of the container 3.
- the product mass is discharged through an open outlet valve at the bottom of the container 3.
- a pressure release takes place.
- a pressure release of the container 3 and the second lid 2 is opened, so that the discharge device 4 can be removed from the container 3 (manually).
- receptacles 41 are preferably mounted on the discharge device, which facilitate manual removal from the container 3.
