Definitions

  • the invention relates to a device for receiving bulk material, granules or blasting material for blasting systems with an inlet opening and an outlet opening and a closing device at least at the outlet opening.
  • the invention is based on the object of designing the device for receiving bulk material in such a way that, among other things, continuous blasting is possible and higher pressures can also be used.
  • the device for receiving bulk material consists of at least a first container and a second container connected to it, which are connected to one another via a connecting piece or a connecting line in order to forward the bulk material, with the bulk material being supplied from the first Container can be interrupted in the second container connected to it by means of a closure device associated with the connecting line.
  • blasting material can be supplied to the blasting system continuously with the pressure in the second container remaining the same, which can be adjusted accordingly, since the second container can be separated from the first container.
  • the first container when using two containers, the first container can also be refilled with blasting material without the second container being affected or pressure fluctuations occurring in the second container. This ensures that the blasting system can always work with constant pressure.
  • the blasting system can advantageously work continuously and at the same time there is always sufficient blasting material available through the first container, since the first container can also be refilled during blasting work.
  • the two containers With the device according to the invention, it is possible for the two containers to be positioned one below the other or one behind the other with respect to the direction of fall of the bulk material are arranged or two or more containers are connected in parallel.
  • the containers arranged one below the other or one behind the other can thus be accommodated in a space-saving manner in an upright or vertically aligned device or a support frame. If the containers are arranged in parallel, the blasting material can be made available to the work process more quickly by switching from one container to another. Furthermore, there is also the possibility to keep different blasting materials in stock in order to call up the corresponding blasting material at short notice depending on the blasting object.
  • blasting material can be made available to the blasting system without long waiting times.
  • the two containers are designed in such a way that they can be supported on a standing surface or are accommodated in a support frame which has at least one support column or two or more support columns which are connected to one another via connecting elements.
  • the connecting elements can be transverse struts or, with respect to the base of the device, horizontally arranged plates which are once connected to the support columns and thus contribute to stiffening the support frame, but which can also be used to accommodate or support the containers.
  • the closure device for the individual containers is designed as a valve, in particular as a pinch valve, which is brought into a closed position and a flow position manually or with the aid of an actuating device can be, so that one container can be easily separated from the other container and thus no mutual influencing of the container during the work process takes place.
  • Pinch valves or hose pinch valves consist of a tubular, round or elliptical passage housing and a piece of elastomer hose inserted in it as a collar, which is sealed at both ends by a flange or a sleeve to the housing. They can be built into the device according to the invention at low cost.
  • a measuring device is provided with regard to the flow direction of the bulk material, which controls the flow rate and/or records the quantity and also ensures that blasting material is always available for the work process.
  • the blasting material discharged from the second container is fed to a blasting device in a time-saving manner.
  • valves are controlled with the aid of a control device and/or actuating device, and the flow rate of the granulate accommodated in the container is thus regulated.
  • Fig.1 shows a device 1 for receiving bulk material, granules or blasting material for blasting systems with an inlet opening 2 and an outlet opening 3, as well as at least one closure device 4, 8 at least at the outlet opening 3 of a first container 5 and a second container 6.
  • the device 1 for receiving bulk material consists at least of the first container 5 and the second container 6 connected to it, which are connected to one another via a connecting piece or a connecting line 7 in order to transfer the bulk material from the first container 5 to the second, with the supply of the Bulk material from the first container 5 into the second container 6 connected to it can be interrupted with the aid of the closing device 8 assigned to the connecting line 7 .
  • the two containers 5, 6 are arranged one below the other or one behind the other with respect to the direction of fall of the bulk material, or two or more containers connected in parallel are provided, one container can be coated with blasting material and the downstream container 6, which is effectively separated from the first container 5, for the blasting process is available.
  • the two containers 5, 6 are designed and arranged in such a way that they can be supported on a standing surface or can be accommodated in a support frame 9, which has at least one support column or two or more support columns 10, which are connected to one another via connecting elements 11.
  • the connecting elements 11 are designed as plates which are connected to the support columns 10 and on which the containers 5, 6 can also be supported.
  • a closure device 4 is provided, which is designed as a valve, in particular as a pinch valve, which can be operated manually or with the aid of a controllable or adjustable device, not shown in the drawing , Actuating device can be brought into a closed and a flow position.
  • the bulk material or granules can be fed to the first container 5 via an inlet funnel 13 .
  • the closure device 4 is provided between an outlet opening 3′ of the inlet funnel 13 and the first container 5, as well as at an outlet opening 3′′ of the first container 5. This makes it possible to separate the first container 5 from the second container 6 during the blasting process and to to supply the upper or first container 5 with blasting material without influencing the downstream container 6, which can then also work with a different or even working pressure.
  • By using at least two containers there is always sufficient blasting agent in the first container 5, which can then be fed to the second container when this has been emptied during the working process.
  • a measuring device 12 which controls the flow rate and/or records the quantity and also monitors the work process and also ensures that there is always sufficient blasting agent available in the first container.
  • the opening times of at least one of the valves can be controlled with the aid of a control device and/or adjusting device and the measuring or regulating device, and the flow rate of the granulate contained in the container (5, 6) can thus be regulated.
