[0032] See Figure 1 and Figure 2 , the present utility model discloses an ultrasonic transducer fixing bracket for fixing an ultrasonic transducer on a screen frame 1 of an ultrasonic vibrating screen, comprising an annular fastener 4, an annular buffer member 9 and a fixing rod 2.
[0033] The annular fastener 4 is an annular clamp, and the clamp comprises an annular clamp body 8 and a lock 7 for tightening the clamp body 8. The clamp body 8 comprises a first arc plate 81 and a second arc plate 82 which are hinged to each other. Both the first arc plate 81 and the second arc plate 82 are semi-circular. The free ends of the first arc plate 81 and the second arc plate 82 can be separated away from each other or buckled towards each other. The free ends of the first arc plate 81 and the second arc plate 82 respectively have wings extending therefrom, and through holes are formed in the wings. A lock 7 which can be opened and closed is arranged in the through holes to apply a radially inward tightening force to the first arc plate 81 and the second arc plate 82. Annular grooves are formed in the inner circumferences of the first arc plate 81 and the second arc plate 82, and the two annular grooves are butted to form an annular groove, and the annular buffer member 9 is embedded in the annular groove.
[0034] The material of the annular buffer 9 can be selected from one of polytetrafluoroethylene, rigid polyurethane foam, glass fiber reinforced rigid foam, etc. It includes a first buffer part 91 and a second buffer part 92 which are oppositely arranged. Both the first buffer part 91 and the second buffer part 92 are semi-circular. Both the first buffer part 91 and the second buffer part 92 include a semi-circular first recess located at their centers. The first buffer part 91 and the second buffer part 92 also include a semi-circular second recess located at one end of each of their respective sides. The two oppositely arranged first recesses form a transducer fixing hole 10, and the two oppositely arranged second recesses form a high-frequency data line fixing hole 11. The dividing line between the first buffer part 91 and the second buffer part 92 divides the transducer fixing hole 10 and the high-frequency data line fixing hole 11 into two equal parts, and this dividing line is collinear with the central connection line of the transducer fixing hole 10 and the high-frequency data line fixing hole 11. The first buffer part 91 and the second buffer part 92 can be separated from each other or fastened under the action of a tightening force. The transducer fixing hole 10 is located at the center of the annular buffer 9, and the high-frequency data line fixing hole 11 is located on the radial side of the transducer fixing hole 10 and axially penetrates the annular buffer 9. The first buffer part 91 is embedded in the annular groove of the first arc plate 81, and the second buffer part 92 is embedded in the annular groove of the second arc plate 82. By fixing the high-frequency data line 5 through the high-frequency data line fixing hole 11, the phenomenon of loose connection between the male and female connectors of the high-frequency data line 5 and the transducer body 3 can be avoided.
[0035] Four fixing rods 2 are provided. The four fixing rods 2 are equally spaced in the circumferential direction of the annular fastener 4. Among them, the first arc plate 81 is provided with insertion holes. One end of each of the four fixing rods 2 is respectively connected to the sieve frame. The other ends (free ends) of three of the fixing rods 2 are fixed to the second arc plate 82, and the other end (free end) of the other fixing rod 2 is inserted into the insertion hole of the first arc plate 81, that is, the other end of this fixing rod 2 is detachably connected to the first arc plate 81. The annular fastener 4 and the sieve frame 1 are respectively fixedly connected to both ends of the fixing rod 2. Compared with the traditional structure of two horizontal fixing rods 2, the structural stability is significantly improved, and the loosening of the connection between the transducer and the sieve wire frame caused by the loosening of the fixing rod can be effectively avoided. When it is necessary to open the first arc plate 81 and the second arc plate 82, first pull out one of the fixing rods 2 from the insertion hole of the first arc plate 81. Conversely, when it is necessary to fasten the first arc plate 81 and the second arc plate 82, after the first arc plate 81 and the second arc plate 82 are fastened and locked, then insert one of the fixing rods 2 into the insertion hole of the first arc plate 81.
[0036] In some embodiments, two or more groups of fixing rods 2 are respectively provided on the first arc plate 81 and the second arc plate 82. The free ends of the fixing rods 2 are fixed to the sieve frame, and adjacent two groups of fixing rods are equally spaced.
[0037] The buckle 7 includes a fastening bolt and a nut. The fastening bolt passes through the through hole on the wing plate, and the fastening bolt is in threaded engagement with the nut. Tightening the nut can force the first arc plate 81 and the second arc plate 82 to approach each other, causing the clamp body 8 to tighten towards its center to squeeze the annular buffer 9, and forcing the annular buffer 9 to tighten towards the centers of the transducer fixing hole 10 and the high-frequency data line fixing hole 11. It can be seen that the present disclosure can apply a radial tightening force to the free ends of the first arc plate 81 and the second arc plate 82 by the cooperation of the nut and the fastening bolt.
[0038] During use, the transducer body 3 and the high-frequency data line 5 are installed in the annular buffer 9, and then the two dockable parts of the clamp body 8 are closed, and the clamp body 8 is locked by the buckle 7. The transducer body 3 is connected to the screen frame by the waveguide rod 6.
[0039] Furthermore, multiple deformation notches 12 are axially formed through the annular buffer 9. The deformation notches 12 can be evenly distributed around the circumference of the transducer fixing hole 10 or evenly distributed around the circumference of the high-frequency data line fixing hole 11. The setting of the deformation notches 12 improves the compatibility of the annular buffer 9 with transducer bodies 3 of different models or high-frequency data lines 5 of different models.
[0040] In summary, the utility model fixes the transducer body 3 and the high-frequency data line 5 simultaneously, avoiding the virtual connection between the high-frequency data line 5 and the male and female connectors of the transducer caused by the vibration generated during the operation of the ultrasonic vibrating screen, which can extend the service life of the transducer. Moreover, the clamp body 8 contains the annular buffer 9 made of non-metallic material. The annular buffer 9 can not only effectively fix the transducer body 3 and the high-frequency data line 5, but also, being made of non-metallic material, can effectively prevent the metal shell of the transducer from being worn. It solves problems such as frequent damage of the transducer, scorching of the screen, and damage of the screen frame, extends the service life of the transducer, more than doubles the service life of the transducer, and improves the working efficiency of the ultrasonic vibrating screen.
[0041] In a second aspect of the present utility model, there is provided an ultrasonic vibrating screen, including a screen frame 1, an ultrasonic transducer fixing bracket, and an ultrasonic transducer. The ultrasonic transducer fixing bracket includes any one of the ultrasonic transducer fixing brackets in the first aspect of the present utility model. The ultrasonic transducer includes a transducer body 3, a waveguide rod 6 connected to the transducer body 3, and a high-frequency data line 5. The transducer body 3 is arranged in the transducer fixing hole 10, the high-frequency data line 5 is arranged in the high-frequency data line fixing hole 11, and the waveguide rod 6 is connected to the screen frame of the ultrasonic vibrating screen.
