DETAILED DESCRIPTION

[0018] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

[0019] like Figures 1 to 4 In one embodiment of the screening device for high-efficiency desulfurizer processing of the present invention shown in the figure, a feed port 11, a vibration motor 12, and a shock-absorbing strut 13 supporting the body 1 are provided on the body 1, and are characterized in that: it includes at least two levels of stacked screening devices 3; the screening device 3 includes a screen frame 31 hinged on the inner wall of the body 1 and capable of swinging back and forth, a discharge bin 32 on the side away from the feed port 11, and a driving device 33 for driving the screen frame 31 to swing back and forth; a discharge port 321 is provided on the discharge bin 32; a guide rod 311 extending out of the side wall of the body 1 is provided at the end of the screen frame 31 close to the discharge bin 32; a guide hole 14 for the guide rod 311 to pass through is provided on the side wall of the body 1; the driving device 33 includes a hydraulic rod 331 fixed on the outer wall of the body 1, and a guide block 332 arranged at the moving end of the hydraulic rod 331; the guide block 332 is provided with a through hole 333 for the guide rod 311 to pass through; the guide rod 311 can slide horizontally in the through hole 333. By designing a swingable screen frame controlled by a telescopic hydraulic rod, the screen is divided into two parts, ensuring sufficient screening time, and ensuring the transmission and collection efficiency of the screened materials, thereby ensuring screening efficiency.

[0020] Specifically, a hinge shaft 34 is provided on the inner wall of the body 1, articulating the middle portion of the screen frame 31. The hinge shaft 34 is positioned between one-quarter and one-half of the side of the screen frame 31 near the discharge bin 32. By designing the hinge shaft in the middle portion of the screen frame near the discharge bin, the screen frame is supported while ensuring that a relatively short extension and retraction distance of the hydraulic rod allows the screen frame to be deflected at a relatively large angle, further enabling rapid collection of the desulfurizer particles after screening.

[0021] Specifically, a support platform 15 for supporting the end of the sieve frame 31 is provided on the inner wall of the machine body 1 ; an arc-shaped wall 16 is provided on the inner wall of the machine body 1 to fit with the end of the sieve frame 31 when the sieve frame 31 swings.

[0022] Specifically, the body 1 is provided with a material guiding device 2 for guiding the material into the feed port 11; the material guiding device 2 includes two material guiding plates 21 respectively arranged on opposite side walls; the two material guiding plates 21 are arranged to be inclined downward in the direction away from their fixed ends; the lowermost material guiding plate 21 is inclined downward in the direction away from the unloading bin 32.

[0023] Specifically, an upward arc-shaped guard plate 312 is provided at one end of the screen frame 31 close to the feed port 11 .

[0024] Specifically, when the end of the sieve frame 31 away from the discharge bin 32 is placed in the lowest position, the angle between the sieve frame 31 and the horizontal plane is 4° to 6°.

[0025] Specifically, the bottom plate of the discharge bin 32 is arranged to be inclined downward in a direction close to the discharge port 321; and two adjacent discharge ports 321 are arranged on opposite side walls.

[0026] Working principle: The staff conveys the material into the feed port 11. The desulfurizer is guided by two staggered guide plates 21. The desulfurizer particles are dispersed and slide on the guide plates 21 under the action of the vibrating body 1, and the material is scattered on the screen frame 31 away from the discharge bin 32. The vibrating screen frame 31 screens the material. During use, the hydraulic rod 331 contracts, driving the screen frame 31 away from the discharge bin 32 to swing to a horizontal position. After that, the hydraulic rod 331 extends, driving the screen frame 31 away from the discharge bin 32. 2 falls again, and while vibrating and screening, the inclination angle of the screen frame 31 is adjusted to disperse and screen the materials gathered at the end of the screen frame 31 again, and re-aggregate them. The appropriate screening time is set according to the material particle size ratio. After the feeding is suspended and the preset time is reached, the hydraulic rod 331 continues to contract, driving the end of the screen frame 31 close to the discharge bin 32 to fall to the lowest position. The vibrating screen frame 31 drives the materials to quickly gather towards the discharge bin 32, which ensures the screening time while improving the collection efficiency of the screened materials at all levels.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
