Description

Screen frame fastening structure on ultrasonic material inspection screen

Technical Field

The utility model belongs to inspection sieve equipment field relates to a reel fastening structure on ultrasonic wave material inspection sieve particularly.

Background

The existing inspection sieve for screening precision detection mainly depends on a vibrating motor or a vibrator to drive a screen to vibrate, and the screen is vibrated and the screening time is prolonged to achieve the purposes of more accurate data information and screening. In the screening process, the existing inspection screen mostly utilizes ultrasonic waves to generate high-frequency vibration, so that the adsorption force among material particles can be effectively stripped, the vibration force of the material on the screen surface is increased, and the material is enabled to pass through the screen quickly, so that the screening efficiency and precision are improved.

The prior patent "03209035.8" granted by the national intellectual property office is named as: an ultrasonic vibration inspection screening machine. The locking device comprises a screening head, a locking pull rod and a tray, wherein the screening head and the tray are respectively positioned at the upper end and the lower end of the screening tool, and the screening head and the tray are connected with each other by penetrating through the locking pull rod. This locking device fastening effect is not good, and the sieve utensil is whole easily to remove in the tray plane or the sieve utensil easily takes place the dislocation each other during the vibration, and then influences the screening result.

SUMMERY OF THE UTILITY MODEL

To the technical problem, the utility model aims to provide an use can fix a position the fastening structure of fastening reel on ultrasonic wave material inspection sieve.

The utility model aims to solve the problems that the screen frame is divided into an upper screen frame body and a lower screen frame body by a screen, the inner diameter of the lower screen frame body is equal to the outer diameter of the upper screen frame body, two clamping grooves are arranged at the relative position of the bottom of the lower screen frame body, two clamping blocks are arranged at the relative position of the upper part of the upper screen frame body, and the at least two screen frames are superposed up and down through the clamping blocks and the clamping groove structures to form the screen body; the central position is equipped with circular constant head tank on the tray, and the bottom card of screen frame is in this constant head tank, and two sleeves vertical fixation are in the both sides of the circular constant head tank on the tray, and the lower extreme of screw rod inserts in this sleeve and is fastened by fastening screw, and the upper end is pressed the clamp plate tightly in the upper end of screen frame through fastening nut. The screen is formed by stamping a steel plate.

The utility model discloses has following effect: this technical scheme adopts sleeve, screw rod, clamp plate can be with the whole body pressure of screen frame to on the tray, can fix a position the screen frame on the tray through the constant head tank, through upper and lower screen frame body and fixture block, draw-in groove mechanism between each screen frame, can fold each screen frame firmly together, consequently, this technical scheme can guarantee that the screen frame is not in disorder at the vibration in-process to improve final screening precision.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 and 2, a screen frame fastening structure on an ultrasonic material inspection screen comprises a tray 2, a screw 6 and a pressing plate 7. The screen frame 9 is divided into an upper screen frame body 93 and a lower screen frame body 94 by a screen 95, the inner diameter of the lower screen frame body 94 is equal to the outer diameter of the upper screen frame body 93, two clamping grooves 91 are arranged at opposite positions of the bottom of the lower screen frame body 94, two clamping blocks 92 are arranged at opposite positions of the upper part of the upper screen frame body 93, and the at least two screen frames 9 are overlapped up and down through the clamping blocks 92 and the clamping grooves 91 to form the screen body 10; the central point puts and is equipped with circular constant head tank 3 on tray 2, and the bottom card of screen frame 10 is in this constant head tank 3, and two sleeves 4 vertical fixation are in the both sides of circular constant head tank 3 on tray 2, and the lower extreme of screw rod 6 inserts in this sleeve 4 and is fastened by fastening screw 5, and the upper end is pressed the clamp plate 7 tightly in the upper end of screen frame 10 through fastening nut 8. The sleeve 4, the screw 6, the fastening screw 5, the fastening nut 8 and the pressing plate 7 can integrally press the screen body 10 on the tray 2, so that the screen body 10 is prevented from moving in the vertical direction during vibration; the positioning groove 3 can position the sieve body 10 on the tray 2 to prevent the sieve body 10 from moving on the tray 2; the frames 9 are vertically stacked by an upper frame 93, a lower frame 94, a latch 92 and a catch groove 91 to prevent the frames 9 from being misaligned during vibration. The screen 95 is stamped from sheet steel and can screen heavy, large particle materials and improve the durability of the screen.
