Definitions

  • the invention relates to a device for removing predetermined amounts of liquid lead from a molten bath with the aid of at least one movable measuring container which, depending on its position, can either be filled with the molten material or from which the molten material can be emptied.
  • valve devices are used which allow the flow of a certain amount of material by specifying the opening time of the valve.
  • GB-PS 1 115 395 valve valves working in this sense are described.
  • their control mechanism is complex and, apart from the risk of incrustation and dripping errors, is not very reliable.
  • valve arrangement according to DE-PS 25 30 102 may be mentioned as an example of another dosing principle in which a flow for the lead is opened or closed again by a rotary movement.
  • a rotatable valve head is placed on a valve body with outlet bores that is firmly inserted into the molten bath tank and has peripheral free cutouts with axial recesses in the form of slots that have to be made to coincide with the outlet bores in order to open the valve.
  • the liquid lead can thus flow directly from the valve into the molds.
  • Such a device is a rotating measuring valve known from DE-OS 1 902 489. It consists in its core of two came arranged on a rotating valve part along a circular line Mer-like recesses, which are rotated alternately with an inlet channel and an outlet channel in connection with the rotation over a work surface, wherein one recess fills, the other empties, but never a recess is connected to both channels simultaneously, so that the volume of the Different filling quantities are excluded.
  • the invention has for its object to provide a metering device for molten lead according to the generic term that initially allows the exact removal of larger portions of liquid lead from a bath tank, is easy to use and still works with great repeatability. Furthermore, if possible, several doses should be possible at the same time.
  • the core of the invention is a box-shaped metering slide which, sliding back and forth on the bottom of a melt pool container, absorbs as much lead as its volume in the one end position from the surrounding and projecting melt pool, and this content in the other end position through a discharge channel emptied in the bottom of the melt tank, which then covers an opening in the bottom part of the metering slide.
  • the metering device consists of a steel container 1 equipped with heating coils 2 and thermal insulation 3, which contains the lead 4 to be metered and on the bottom of which a metering slide 5 slides along a guide 6 between two end positions.
  • the metering slide can also comprise several chambers 7, which are in front of or behind the plane of the drawing.
  • the chambers can also be staggered in the longitudinal direction and assigned to one another at fixed intervals, as required by a plurality of casting molds predetermined in a specific orientation. In this way, for example, all forms to be poured out with lead for the cell connectors, pole bridges and end poles of a multi-cell battery can be filled in a single work cycle.
  • an emptying channel 8 is provided in the bottom of the steel container and an outlet opening 9 is provided in the bottom part of the chamber itself, while the cover part 10 of the metering slide has an inlet opening 11 and an additional opening 12 for each chamber.
  • the metered amount can be adapted to changing conditions via the thickness of the cover part 10. With the force of a spring 13, a pressure piece 14 presses on this cover part 10, which is held in an immovable position by a steel plate 15 firmly connected to the steel container 1 and which provides the upper slide and sealing surface for the metering slide with free play.
  • the pressure piece contains in the form of bores a filling channel 16 and a ventilation channel 17 for each chamber.
  • an inert gas can be applied to the ventilation duct.
  • the pressure piece is a steel part
  • the metering slide and associated cover are expediently made of gray cast iron.
  • a pneumatic cylinder 18 is very favorable for moving the metering slide between two end positions.
  • FIG. 2 shows the outline or the width of the metering device according to FIG. 1 when the metering slide is equipped with a double chamber (the metering slide itself is not visible) and the guidance of the heating coils 2.
  • the amount of lead in the chamber 7 runs straight through the outlet opening 9 and the emptying channel 8. At the same time, the chamber is ventilated via the inlet opening 11 and bore 17.
  • the metering slide is then moved into its left end position, at which outlet opening 9 is closed, whereas inlet opening 11 with filling channel 16 and the additional opening 12 with ventilation channel 17 are in register. By filling the chamber with lead, it also vents through channel 17.
  • the device After moving to the right starting position and emptying, the device is ready for the next dosing process.
  • the new lead metering device has a number of significant advantages. It enables the casting molds to be supplied with precisely measured quantities of lead, without having to adjust or readjust anything. The nominal thicknesses of pole bridges can therefore be adhered to exactly. This saves lead, and the welding of the plate flags is more even due to constant amounts of lead and therefore constant amounts of heat.
  • the structure of the device allows easy adjustment and change of the dosing quantity.
  • the outlet openings or emptying channels can be selected to be large, which means that small dosing times are possible. They can be folded closely together for filling points that are close together. They are short and are fully opened so that hardly any slag can settle. They can be cleaned during operation with a tool that fills the entire hole.
  • the device is easy to dismantle for maintenance work because most of the individual parts are inserted. No narrow tolerances have to be observed when manufacturing the individual parts.
  • the sealing surfaces are easy to manufacture because they are flat surfaces. Cheap materials are used. The sealing surfaces are always free of play due to the spring action.
