Definitions

  • the invention relates to a sieve frame for an ultrasonic sieve with the features of the preamble of claim 1 protection and an ultrasonic sieve with the features of the preamble of claim 5 protection.
  • Ultrasonic sieving especially of plastic powders in the powder coating process, has two major problems:
  • the sieve frame according to the invention for an ultrasonic sieve has an upper side for fastening a sieve fabric, an underside lying opposite the upper side and an opening enclosed by the sieve frame, through which the sieve material, when the sieve - e.g. is used in a screening machine, flows through it.
  • the respective size is always in the direction of the direct th path between the top and bottom of the screen frame to mes ⁇ sen.
  • the invention is characterized in that the screen frame has at least one running around the opening groove, so that the interim ⁇ rule which faces the opening edge of the groove and the opening lying part of the screen frame forms a fabric sound conductor, the one with regard to the transmission of ultrasound from The outer screen frame formed by the unmodified rest of the screen frame is at least partially decoupled.
  • groove is broad and functionally interpreted.
  • a groove in the sense of this protective rights application is present both when the depression has been produced by removing material from the sieve frame and when the sieve frame consists of a first part forming the tissue sound conductor, an outer frame and one between the tissue sound conductor and the outer frame disposed and connected to or connected to the web having a thickness that is less than the thickness of tissue sound conductor and outer frame composed.
  • the use of the term "bar" should not imply that the interim ⁇ 's fabric sound conductor and outer frame extending rib in a direction lateral to its extending direction of an edge must have, in particular, is the complement to a running order ⁇ groove whose beginning and end coincide, also called bridge.
  • a sieve frame comprising an outer sieve frame, which is connected to a fabric sound conductor only via individual struts, between which a material passage from the Top to bottom of the screen frame is possible, not the invention.
  • the groove is arranged on the upper side of the screen frame.
  • the top of the screen frame is, as already defined above, the side of the screen frame over which the screen cloth is pulled.
  • an adhesive ⁇ layer can be used in the attachment of the mesh fabric, which covers the groove, so that can penetrate from any side of the groove to sieving material in this, which significantly simplifies the cleaning of the sieve frame ⁇ .
  • the ultrasound sieve according to the invention has a sieve frame, a screen fabric stretched on the sieve frame, a tissue sound conductor for introducing ultrasound into the screen fabric stretched on the screen frame, an ultrasound converter for generating ultrasound and a feed sound conductor for supplying the ultrasound generated by the ultrasound converter to the tissue sound conductor.
  • the screen frame to-least an upper surface on which the mesh is attached, a top surface opposite the bottom and surrounded by the screen frame opening through which can flow the material to be sieved when it hin mange ⁇ reached through the screen.
  • the sieve frame has at least one groove running around the opening, so that the part of the sieve frame lying between the edge of the groove facing the opening and the opening forms a tissue sound conductor which is unmodified with regard to the transmission of ultrasound.
  • the rest of the screen frame formed outer screen frame of the screen frame is at least partially decoupled.
  • the tissue in other words, the invention sound conductor a defi ⁇ ned by being a sealed from the screen frame aperture current, arranged in the screen frame groove portion of the screen frame, the transmission with regard to the Ü of ultrasound at least partially from the remainder of the screen frame is decoupled.
  • the sieve cloth is fastened to the sieve frame with an adhesive layer and the adhesive layer extends over the groove so that the groove or its opening in the direction of the top of the sieve frame is closed by the adhesive layer.
  • the adhesive layer extends over the groove so that the groove or its opening in the direction of the top of the sieve frame is closed by the adhesive layer.
  • Figure la shows a top view obliquely from above of an ultra ⁇ schallsieb 10 defining an opening 20 and 6, with a sieve frame on top of the screen mesh disposed reasonable Furthermore, one recognizes an ultrasonic ⁇ converter 5 for generating ultrasound with a screen frame 1, and a feed sound conductor 4. How the ultrasound from the ultrasonic converter 5 is introduced into the screen cloth 6 using the feed sound conductor 4 will be explained below in detail.
  • FIG. 1a The construction of the screen frame 1 shown in FIG. 1a can be explained particularly well in the cross-sectional view of FIG. 1b. Since it is a cross-section through a symmetrically structured structure, only the right side of the figure has been provided with reference numerals, but the left side of FIG. 1b is constructed identically from outside to inside as the right side is viewed from outside to inside , This figure reveals that the screen frame 1 has a groove 9 whose bottom is formed by a web 2, which is shown for better illustration or emphasis in Figure lb as a bold line.
  • This groove 9 divides the screen ⁇ frame 1 in a tissue sound conductor 3 through the area of the screen frame 1, between the opening 20 facing the edge 8 of the screen frame 1 and the opening 20 facing (that is, the opening 20 nearer) edge 22 the groove 9 and an outer screen frame 23, which is formed by the unmodified rest of the screen frame 1 on.
  • the feeding sound conductor 4 is such ent ⁇ coupled through the outer screen frame 23 passed through, that it does not transmit vibrations to this part of the screen frame over ⁇ so that only a direct excitation of the tissue ⁇ sound conductor 3 forming part of the screen frame 1 is performed.
  • This can be achieved in a particularly advantageous manner, when the feed sound conductor 4 is passed through a hole in the outer screen frame 23, and the area of this passage is sealed by the sealant with a hole, because so the penetration of powder is effectively prevented, although a extensive vibrational decoupling between Feed sound conductor 4 and outer screen frame 23 consists.
  • the tissue sound conductor 3 then initiates the ultrasound into the mesh screen 6.
  • Sieve frame 1 from, but it has proved to be particularly useful to set a web thickness of 1 mm.

Abstract

L'invention concerne un cadre de tamis (1, 51) pour un tamis à ultrasons (10, 50), qui comprend une face supérieure permettant la fixation d'une toile de tamisage (6, 56), une face inférieure opposée à la face supérieure et une ouverture (20, 60) entourée par le cadre (1, 51) du tamis. Selon l'invention, le cadre de tamis (1, 51) comporte au moins une rainure (9, 59) s'étendant autour de l'ouverture (20, 60), de sorte que la partie du cadre (1, 51) qui est située entre le bord (22, 62) de la rainure (9, 59) orienté vers l'ouverture (20, 60) et l'ouverture (20, 60) forme un conducteur acoustique de toile (3, 53) qui est au moins partiellement découplé du reste (23, 63) du cadre (1, 51) du point de vue de la transmission des ultrasons.
