Definitions
- the invention relates to an electrical separator according to the preamble of claim 1.
- Such a device is known from DE 197 01 463 C1.
- the invention has for its object to support the cheapest possible production, reliable operation and space-saving design of the separator.
- the invention proposes instead of in
- Ceramic insulation usually used in the high-voltage range to use a plastic component which receives the electrodes themselves and the contact surface via which the electrodes can be connected to an electrical lead, the plastic component also being used within this plastic component electrical connecting lines between the contact surface and the electrodes are arranged.
- plastic as an insulator ensures excellent vibration resistance.
- the plastic component with its vibration-damping properties can extend the life of the electrodes, which may be sensitive to vibration.
- the plastic component can be manufactured using the injection molding process, with the remaining components being able to be encapsulated with the aid of this plastic.
- an efficient production of the entire assembly is made possible, in which in particular a complex assembly of electrodes, contact area and the electrical connection lines between them can be omitted, and on the other hand a particularly space-saving design of the assembly is possible because the molding around the components mentioned is a more space-saving arrangement enables as if they were fixed to be mounted on the electrode holder.
- Electrodes can also be particularly advantageously designed as a one-piece component, for example in injection molding or in die casting.
- the electrodes are connected to one another and form a one-piece component which also forms the contact surface to which the electrical lead can be connected.
- the electrodes consist of plastic. If these electrodes are embedded in the plastic component mentioned at the beginning, the optimally low-stress behavior of the assembly as a whole results due to similar material properties (e.g. coefficient of thermal expansion), so that their functional reliability and susceptibility to malfunction are further improved.
- a design of the electrodes made of plastic is surprisingly possible, since the functioning of the Electro-separator is based on the electrical conductivity of the electrodes and even plastics that are set to be conductive have a comparatively high resistance to metallic materials that is generally regarded as unfavorable. In view of the low currents, this comparatively higher resistance of plastic electrodes does not play a role that is relevant to the function, so that good separation performance can also be ensured with such a design of the electrodes made of plastic.
- the electrodes, their connecting lines and the contact surface are designed as a one-piece workpiece, a particularly inexpensive manufacture of this workpiece in the plastic injection molding process is possible, so that the electrical separator is particularly favorable in terms of both its manufacturing costs and its operating behavior.
- FIG. 1 shows a schematic, perspective view of an electrode holder of an electrostatic precipitator designed according to the invention and provided with spray electrodes, and
- FIG. 2 shows a vertical section through the electrode holder from FIG. 1.
- the electrode holder 1 denotes an electrode holder in general.
- the electrode holder 1 is made of plastic, it has four bores 2, with the aid of which the electrode holder can be attached, for example in an oil mist-containing component, so that the electrode holder 1 shown is used for separating oil, for example in crankcase ventilation in internal combustion engines can so that the separated oil particles can be returned to the engine in an environmentally friendly manner.
- three electrodes 3 are provided, which are designed as two-stage spray electrodes: These spray electrodes each have a corona area 4, which is designed with a needle-like small diameter, and an electrostatically active area 5 with a considerably larger diameter.
- electrostatically active regions 5 of the electrodes 3 are hollow. These areas of the electrodes 3 consist of an electrically conductive plastic, with 5 metal needles inserted in the tips of these areas, which form the corona areas 4 of the electrodes 3.
- a total of three electrodes 3 are provided, these being connected to one another by a curved ring line 6, and furthermore the electrodes 3 and the ring line 6 are formed in one piece by an injection molded part.
- this component made of electrically conductive plastic is extended radially outwards. In this outer area, the component forms a contact surface 7, which is used to contact an electrical lead.
- the electrode holder 1 is also made of plastic, but from an electrically insulating plastic, with which the electrode assembly is molded. Overall, the assembly shown can therefore be handled in one piece and enables a quick assembly of an electrical separator.
- the electrode holder 1 In the area of the contact surface 7, the electrode holder 1 has a recess 8 which is designed in two stages and which can accommodate the electrical supply line and its insulation, the fastening of this electrical insulation to the electrode holder 1 not being discussed in more detail here.
- a latching surface can be provided on the sleeve formed by the electrode holder 1 and surrounding the recess 8 in order to secure the electrical insulation to the electrode holder 1 by means of a latching or snap connection and to ensure the electrical contacting of the contact surface 7.
- the material of the electrode holder 1 can be configured in two components in order to have both the intended insulating properties and the desired dimensional stability.
- it may be provided not to inject a single material around the electrically conductive components, but instead to use a first material for the electrode holder 1 adjacent to the electrically conductive components and this material surrounding a second material, which is the outer contour of the electrode holder 1 trains.
- the injection-molded, electrically conductive components 3, 6 and 7 are not made from a conductive plastic, but from metal.
- the electrode holder formed from plastic can also have other functions, such as for receiving seals, for receiving fasteners and the like.
