Definitions
- the invention relates to a method for handling Bulk goods and suitable container constructions for Implementation of the procedure, especially for poorly flowing ones Bulk goods according to the type of process and the device claims.
- the invention has for its object a method and to further develop a container of the type specified at the beginning, that residual emptying in a simple way the container is guaranteed even with poorly flowing material is.
- the method according to the invention can be advantageous Way a good residual emptying by the air flow between the fixed outer wall of the container and the flexible Inner part can be reached.
- the air flow pulsates at a relatively high rate Frequency, so that adhering bulk particles on the inner part be removed reliably and the container as such almost residue-free even with poor flowing Bulk material is emptied.
- the intensity of this activation can be the air flow in the simplest way through an in the air supply built-in, preferably manually operated, throttle valve regulate.
- the air supply and discharge can in an advantageous manner in a closed system respectively.
- the process is called the container for the bulk material operated a suction scale, where it is particularly important that a complete emptying of the bulk goods after every weighing process is guaranteed.
- the Container which is preferably on load cells, load cells or is stored in a weighing frame, by means of a pneumatic conveyor system filled in suction or pressure mode and when the desired target weight is reached Promotion in a manner known per se by means of valves and controls switched off.
- This process can for one or more components.
- the air circuits caused by a blower for the suction or Printing process in an advantageous manner with the further Air circuit for residual emptying described above can be combined by an appropriate valve control.
- FIG. 1 shows a schematic side view of a container construction which is said to have a container 1 for the metering of bulk material with an almost circular container cross section of> 1 m 2 .
- the container 1 shown here consists of a cylindrical Upper part 2 and a conical lower part 3 and is lined with a flexible inner part made of rubber 4 into one, not shown here, for example difficult-to-flow bulk goods can be introduced.
- the Inner part 4 is fully conical, so that in In the idle state, an air space 5 between the flexible inner part 4 and the outer wall (parts 2,3) of the rigid container 1 forms.
- the flexible inner part 4 lies against the rigid container parts 2.3 so that the entire contents of the container 1 can be used.
- the container 1 is filled over one or more inlet connections 6 on a cover 7.
- the container can also be operated open if the material to be handled permits.
- the Container 1 can be at the bottom of an outlet 8 with a shut-off device 9, which as a slide, as a rotary flap, or can be designed as a pinch valve, closed will.
- This mechanical activation of the inner part 4 takes place evenly rotating with a relatively high vibration frequency, so that even adhering hard-flowing bulk material particles reliable on the inside of the inner part 4 be removed and the container 1 as such almost emptied residue-free even under difficult conditions becomes.
- the intensity of this activation can be for example by a built in the air supply 11, Regulate the manual throttle valve 15.
- the Frequency of vibration leading to this activation results from the design rules of a mechanical Resonant circuit, in addition to the dimensions in particular also the material properties of the inner part 4 and the bulk solids still play a role.
- FIG. 3 In the embodiment of Figure 3 is the container construction executed as a suction balance 21.
- a suction balance 21 This exists from a metallic container wall 22, a flexible Inner part 23 (comparable to the inner part 4 according to Figure 1), a built-in filter 24 and one pneumatically operated outlet flap 25.
- the metallic Container wall 22 of the suction balance 21 is here at least 3 pressure cells 26 stored and via a delivery line 27 with a storage silo, not shown, or also with connected several silos for the bulk material to be fed.
- Suction balance is connected to a through a clean air line 28 Blower 29 connected.
- the blower discharge line 30 29 leads to the outside via a valve 31 or via a valve 32 into the air space 33 (comparable to the air space 5 1) between the container wall 22 and the inner part 23.
- a return air line leads from this air space 33 34 to the blower 29. All described above Air lines 28,30,34 are each with elastic connecting elements 35 connected to the container 21 to be weighed, so that no interference with weighing he follows.
- valves 31 and 36 opened and valves 32 and 38 closed.
- the fan 29 sucks air out of the Atmosphere and indicates this air via the valve 31 the atmosphere.
- the shut-off valve 38 is now opened and the ventilation valve 37 and the bypass valve 36 are closed, this creates a conveying air flow in the clean air line 28 or suction that is in the filter 24 in the container 21 and continues in the delivery line 27, so that this results in a pneumatic filling of the container 21 of the suction balance is effected.
- An air space 33 prevails during this filling process negative pressure greater by the air resistance of the filter 24 than inside the container 21 or the inner part 23. Because of this and due to the weight of the bulk material, the flexible inner part 23 becomes close to the container wall 22 pressed and it is so during the filling optimal use of the container volume.
- the aforementioned idle mode is also activated.
- the drain valve is now used to empty the suction scale 25, the ventilation valve 37 and the valve 32 opened and there will be shut-off valve 38, valve 36 and the valve 31 closed. Then it works over the ventilation line (comparable to the air intake 8 according to Figure 1) in the lower end of the cone of the container 21 entering air flow a strong vibration of the elastic Inner part 23, thereby emptying the container 21 in the same way as in the first embodiment is supported.
