[0003] In the process of refractory material screening, how to achieve multi-stage screening while maintaining the effect of vibratory screening is an urgent problem to be solved.

[0004] Therefore, it is essential to provide a material screening device for refractory material processing to address the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a material screening device for refractory material processing. This device uses four vibrating screen components and screening scrapers in movable cooperation to achieve vibration screening of refractory materials according to aperture size within the multi-stage vibrating screen plate components. By utilizing the actuation cooperation of the screening scrapers and movable balls, and by using the connection of return springs and limiting baffles, the vibration screening effect can be maintained, and multi-stage screening can be achieved, thereby improving the screening efficiency of refractory materials.

[0006] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0007] A material screening device for refractory material processing is provided, including a screening positioning ring plate, several support columns fixedly installed at the bottom of the screening positioning ring plate, a positioning cover plate fixedly installed above the screening positioning ring plate, a feed inlet and a rotating motor fixedly installed above the positioning cover plate, a rotating shaft fixedly installed at the output end of the rotating motor, the rotating shaft rotatably extending into the interior of the positioning ring plate, a screening actuating scraper fixedly installed on the side wall of the rotating shaft, a multi-stage vibrating screen plate assembly movably sleeved on the rotating shaft, and a limit ring plate fixedly installed at the bottom of the rotating shaft.

[0008] Specifically, the multi-stage vibrating screen plate assembly includes an outer tube, on which four limiting baffles are installed in a circumferential array. The ends of the four limiting baffles away from the outer tube are movably fitted with the side wall of the positioning ring plate. Between adjacent limiting baffles, a first-stage vibrating screen assembly, a second-stage vibrating screen assembly, a third-stage vibrating screen assembly, and a direct-exhaust vibrating screen assembly are installed on the side wall of the outer tube along the rotation direction of the rotating shaft.

[0009] The inner wall of the positioning ring plate is also equipped with four upper limit plates and four lower limit plates of the same height.

[0038] The present invention will be further described in conjunction with the following embodiments.

[0039] Example 1:

[0040] like Figures 1-4As shown, a material screening device for refractory material processing includes a screening positioning ring plate 1. Several support columns 2 are fixedly installed at the bottom of the screening positioning ring plate 1. A positioning cover plate 3 is fixedly installed above the screening positioning ring plate 1. An inlet 4 and a rotating motor 5 are fixedly installed above the positioning cover plate 3. A rotating shaft 6 is fixedly installed at the output end of the rotating motor 5. The rotating shaft 6 extends rotatably into the interior of the positioning ring plate. A screening actuating scraper 7 is fixedly installed on the side wall of the rotating shaft 6. A multi-stage vibrating screen plate assembly is also movably sleeved on the rotating shaft 6. A limit ring plate 8 is fixedly installed at the bottom of the rotating shaft 6.

[0041] This application is used for vibratory multi-stage screening of refractory materials. First, the refractory material is positioned as a whole by the screening positioning ring plate 1 and the support column 2, and enters the interior of the screening positioning ring plate 1 through the feed port 4. At the same time, the rotation of the rotating motor 5 and the rotation of the positioning ring plate realizes the sieving of the refractory material. The multi-stage screen plate assembly supports the refractory material raw material entering from the feed port 4, and the bottom limiting ring plate 8 can prevent the multi-stage vibrating screen plate assembly from falling off.

[0042] The multi-stage vibrating screen plate assembly includes an outer tube 9. Four limiting baffles 10 are installed in a circumferential array on the outer wall of the outer tube 9. The ends of the four limiting baffles 10 away from the outer tube 9 are movably fitted with the side wall of the positioning ring plate. A first-stage vibrating screen assembly, a second-stage vibrating screen assembly, a third-stage vibrating screen assembly, and a direct-exhaust vibrating screen assembly are installed on the side wall of the outer tube 9 between adjacent limiting baffles 10 along the rotation direction of the rotating shaft 6.

[0043] The multi-stage vibrating screen plate assembly is movably connected to the rotating shaft 6 through the outer sleeve 9, and forms a basic structure through four limiting partitions 10. The first-stage vibrating screen assembly, the second-stage vibrating screen assembly, the third-stage vibrating screen assembly and the direct-exit vibrating screen assembly are interspersed in the middle to perform multi-stage vibrating screening of refractory materials.

[0044] Four upper limit plates 11 and four lower limit plates 12 of the same height are also installed on the inner side wall of the positioning ring plate. The top of the four limit plates 10 is movably embedded in the upper limit plates 11, and a return spring 13 is installed between the bottom of the four limit plates 10 and the four lower limit plates 12.

[0045] The upper limit plate 11 is embedded in the upper surface of the four limit partitions 10, which can avoid obstructing the movement of the screening scraper 7. At the same time, the installation of the lower limit plate 12 and the return spring 13 allows the four limit partitions 10 to move up and down elastically to achieve a vibration effect.

[0046] The primary vibrating screen assembly, the secondary vibrating screen assembly, the tertiary vibrating screen assembly, and the direct-exhaust vibrating screen assembly all include two vibrating support rods 14 extending from the outer sleeve 9 to the positioning ring plate, and several movable ball bearings 15 are installed above the vibrating support rods 14.

[0047] The upper surfaces of the primary screen 16, the secondary screen 17, the tertiary screen 18, the vibrating strut 14, and the limiting partition 10 are at the same height, while the top of the movable ball 15 is higher than the height of the upper surface of the vibrating strut 14.

[0048] When the screening scraper 7 rotates, it drives the refractory material to rotate and move. The movable ball 15 on the vibrating support rod 14 comes into contact with the screening scraper 7, and the screening scraper 7 generates downward pressure on the vibrating support rod 14. After the screening scraper 7 passes the movable ball 15, the vibrating support rod 14 returns to its original height, which drives the entire multi-stage vibrating screen plate assembly to vibrate up and down, achieving the effect of vibrating screening.

[0049] The primary vibrating screen assembly also includes a primary screen 16 installed outside the vibrating strut 14, the secondary vibrating screen assembly also includes a secondary screen 17 installed outside the vibrating strut 14, and the tertiary vibrating screen assembly also includes a tertiary screen 18 installed outside the vibrating strut 14.

[0050] The apertures of the primary screen 16, secondary screen 17, and tertiary screen 18 increase sequentially along the rotation direction of the screening scraper 7. The direct-leak vibrating screen assembly does not have screens, allowing the large-aperture refractory material to pass directly through. The discharge pipe is directly connected below the primary screen 16, secondary screen 17, tertiary screen 18, and the direct-leak vibrating screen assembly.

[0051] This invention utilizes four vibrating screen components in conjunction with the screening actuating scraper 7 to enable refractory materials to be vibrated and screened according to aperture size within the multi-stage vibrating screen plate assembly. By utilizing the actuating cooperation between the screening actuating scraper 7 and the movable ball bearing 15, and by connecting the return spring 13 and the limiting partition 10, the vibrating screening effect can be maintained while multi-stage screening is achieved, thereby improving the screening efficiency of refractory materials.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
