Background

Oxytetracycline hydrochloride, also known as oxytetracycline, is a spectrum bacteriostatic agent. The existing oxytetracycline hydrochloride particle size detection method is a manual screening method, and the method is long in time consumption and low in detection result accuracy.

At present, the international mechanical screening method mainly comprises a dry screening method and an acoustic velocity screening method. Review of the relevant data reveals that dry screening is long in service and is unlikely to be reproducible using mechanical dry screening if the particles remaining on the screen are aggregate rather than single particles.

Sonic sieving, which uses an ultrasonic vibrating sieve to sieve, is a method in which a sample is placed in a vertically oscillating gas column that lifts the sample at a given pulse frequency and returns it through a mesh, is shorter in use than dry sieving, and may be more effective for sieving powders or particles.

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The invention will be further elucidated with reference to the drawing.

As shown in fig. 1, the utility model discloses an ultrasonic vibration sieve for particle size detection of oxytetracycline hydrochloride, including base 1, pendulum 3, support frame 4, underframe 5, reel 6, shield 7, ultrasonic connector 13 and closing device 14.

The base 1 is fixedly arranged on the ground feet 2; can set up the ground callus on the sole under lower margin 2, the ground callus on the sole is the rubber material, plays the cushioning effect, reduces ultrasonic vibration sieve's loss.

A vibrating body 3 is arranged on the base 1, and the vibrating body 3 is driven by a vibrating motor; the underframe 5, the reel 6 and the shield 7 are arranged on the vibrating body 3 from bottom to top, the reel 6 is at least one, the screen is arranged inside the reel, the number of the reels can be selected according to actual needs, and when the reel is larger than one, the screen falls from top to bottom, the aperture of the screen in the reel is reduced in sequence, and automatic screening is realized.

The pressing device comprises a pull rod and a pressing strip; the pull rod 8 is positioned on the outer sides of the bottom frame 5, the screen frame 6 and the dustproof cover 7, is arranged on the support frame 4, and can be fixedly connected with the pull rod 8 and the support frame 4 through bolts; the layering 9 is located the shield 7 top to establish the draw-in groove 10 in, draw-in bar 8 in layering 9 draw-in groove 10 removes, and adjustment layering 9 and shield 7 interval are fastened through knob 11 on the layering 9, keep the position of underframe 5, reel 6, shield 7 fixed.

The ultrasonic generator 12 is arranged on the outer side of the bottom frame 5 and is connected with the bottom frame 5 through the ultrasonic connector 13, ultrasonic waves are combined with the vibrating body to shock the bottom frame, the screening capacity and the working efficiency are improved, and time and labor are saved.

The utility model discloses still can set up damping spring between underframe and pendulum according to actual need.

During actual operation, the dustproof cover is opened, the oxytetracycline hydrochloride is placed in the screen frame, the dustproof cover is covered, the distance between the pressing strip and the dustproof cover is adjusted, the pull rod is fastened through the knob on the pressing strip, the bottom frame, the screen frame and the dustproof cover are kept fixed in position, and screening operation is carried out.
