Description

Technical Field

[0001] The utility model relates to the technical field of corundum screening, in particular to screening equipment for corundum production. Background Art

[0002] Carborundum is a material made of quartz sand, petroleum coke and sawdust in a resistance furnace through high-temperature smelting. It has the characteristics of good toughness, high microhardness, high volume density and high temperature resistance, and is widely used in various aspects of industrial production.

[0003] Before use, corundum needs to be screened to classify particles of different sizes. However, the current screening work is generally done manually, which is time-consuming and labor-intensive. After screening, it needs to be collected manually, which is troublesome. In addition, the screening is not detailed enough. When screening, a certain amount of dust and debris may be generated, which affects the staff and the working environment.

[0004] For example, the publication number "CN214183979U" provides a device for screening corundum in the production process of diamond wire. The device is provided with a placement box, a connecting shaft and a shaking rod. The rotating motor is started to make the shaking rod hit the placement box, thereby causing the corundum inside the placement box to shake, so that the dust and impurities in the corundum pass through the filter net and fall into the storage box, making it convenient for the staff to screen the corundum.

[0005] However, the above device still has the following problems during implementation:

[0006] When the device is in use, it is unable to screen corundum of different sizes, and screening is required again in subsequent use, which increases the subsequent workload. At the same time, the device is unable to work continuously when in use. After a batch of corundum is filtered, the corundum in the placement box needs to be taken out before the next filtering, which is inefficient. Utility Model Content

[0028] For example, see Figure 1-4 A screening device for producing corundum includes a screening box 1, a feed box 11 is fixedly installed on the top of the screening box 1, and the feed box 11 is connected to the inside of the screening box 1, a screening assembly 3 is arranged inside the screening box 1, and the screening assembly 3 is arranged in an inclined shape, and the screening assembly 3 includes two fixed frames 31, and the inner walls on both sides of the screening box 1 are provided with slide grooves for the two fixed frames 31 to slide, and the two fixed frames 31 are slidably connected to the inner wall of the screening box 1 through adjacent slide grooves, and screening plates 32 are fixedly installed on the two fixed frames 31, and the aperture of the upper screening plate 32 is larger than the aperture of the lower screening plate 32, and one side of the screening box 1 Two discharge ports 12 are also provided on the surface of the screening box 1, and a collecting box 5 is provided below the two discharge ports 12. A plurality of connecting plates 33 are provided between the two fixed frames 31, and the two fixed frames 31 are connected by a plurality of connecting plates 33. A bottom dust collecting box 13 is also slidably connected to the screening box 1, and the bottom dust collecting box 13 is located directly below the screening plate 32.

[0029] When the device is needed, firstly, the corundum to be screened is put into the screening box 1 through the feed box 11, and the corundum falls on the screening plate 32 in the screening box 1. The corundum is screened by the two screening plates 32, and the screened corundum falls on the two discharge plates 34 and is discharged through the discharge port 12 and falls into the collection box 5;

[0030] By providing two screening plates 32, corundum of different sizes can be screened quickly and collected and stored in the collecting box 5, which is simple and convenient to use.

[0031] For example 2, please refer to Figure 1 and Figure 4A water tank 2 is also fixedly installed on the top of the screening box 1, and a water supply pipe 21 is connected to the water outlet end of the water tank 2. A water delivery plate 14 is fixedly installed on the side of the screening box 1 close to the collecting box 5. The end of the water delivery pipe 21 away from the water tank 2 penetrates and extends into the water delivery plate 14. A water delivery pipe is arranged inside the water delivery plate 14, and the water delivery pipe 21 is connected to the water delivery pipe in the water delivery plate 14. The water delivery plate 14 is divided into two horizontal plates and one vertical plate. The two horizontal plates are fixedly installed above the two discharge ports 12 respectively, and one side of the two horizontal plates is connected by the vertical plate. A water inlet pipe 24 is also arranged at the water inlet end of the water tank 2. A plurality of water outlet pipes 22 are fixedly installed at the bottom of the two horizontal plates, and a nozzle 23 is arranged at the bottom of each water outlet pipe 22. The water outlet pipe 22 and the nozzle 23 are both connected to the water delivery pipe in the water delivery plate 14;

[0032] When the screened corundum is discharged through the discharge port 12, the water tank 2 is started to make the water in the water tank 2 flow to the water pipe in the water supply plate 14 through the water supply pipe 21, and sprayed out through the water outlet pipe 22 and the nozzle 23 on the two horizontal plates. By arranging the two horizontal plates above the two discharge ports 12, during discharge, the water mist sprayed downward by the nozzle 23 can absorb the dust and debris generated during discharge, thereby reducing the dust during discharge.

[0033] For example 3, please refer to Figure 1 and Figure 3 , an equipment box 4 is also fixedly installed on the side of the screening box 1 away from the discharge port 12, a servo motor 41 is fixedly installed inside the equipment box 4, the output end of the servo motor 41 is fixedly connected to a rotating disk 42 through a coupling, a connecting shaft 45 is fixedly installed on the top of the rotating disk 42, and the connecting shaft 45 is arranged at an eccentric position of the rotating disk 42, a connecting block 43 is rotatably connected to the top of the connecting shaft 45, one end of the connecting block 43 away from the rotating disk 42 passes through the side wall of the screening box 1 and extends to the inside of the screening box 1, a limiting groove for sliding the connecting block 43 is provided on the side of the screening box 1 close to the connecting block 43, an extended end of the connecting block 43 is fixedly connected to the connecting shaft 45, a connecting frame 44 is fixedly installed on the side of the fixed frame 31 close to the connecting shaft 45, and the connecting shaft 45 is rotatably connected to the connecting frame 44;

[0034] When the corundum falls on the screening plate 32, the servo motor 41 in the equipment box 4 is started, so that the servo motor 41 drives the rotating disk 42 to rotate. When the rotating disk 42 rotates, the connecting block 43 is driven to move outward through the rotating shaft, so that the connecting block 43 pulls the fixed frame 31 to move on the inner wall of the screening box 1 through the connecting frame 44 and the connecting shaft 4545. The rotating disk 42 continuously rotates to drive the fixed frame 31 to move back and forth, so that the screening plate 32 screens the corundum. The two fixed frames 31 can be moved at the same time by the provided connecting plate 33, so that the upper and lower screening plates 32 can screen the corundum at the same time.

[0035] By setting the inclined fixed frame 31 and the screening plate 32, during the continuous movement of the fixed frame 31, the diamond sand moves to a lower position under the action of gravity, falls on the discharge plate 34, and is finally discharged into the collection box 5 through the discharge port 12;

[0036] By setting the rotating disk 42 and the connecting block 43, when in use, the rotating disk 42 can be rotated to make the connecting block 43 pull the fixed frame 31 to move, thereby accelerating the screening speed. At the same time, by continuously moving the fixed frame 31, the corundum on the screening plate 32 can fall onto the unloading plate 34 under the action of gravity, which is convenient for collection.

[0037] Working principle: When in use, first pour the corundum into the screening box 1 through the feed box 11, start the servo motor 41, and make the servo motor 41 drive the rotating disk 42 to rotate. When the rotating disk 42 rotates, the connecting block 43 is driven to move outward through the rotating shaft, so that the connecting block 43 pulls the fixed frame 31 to move on the inner wall of the screening box 1 through the connecting frame 44 and the connecting shaft 4545. The rotating disk 42 continuously rotates to drive the fixed frame 31 to move back and forth, so that the screening plate 32 screens the corundum. The two fixed frames 31 can be moved at the same time through the provided connecting plate 33, so that the upper and lower screening plates 32 can screen the corundum at the same time.

[0038] The fixed frame 31 is constantly moving, so that the corundum on the screening plate 32 falls on the unloading plate 34 under the action of gravity and is discharged through the discharge port 12. When the corundum is discharged from the discharge port 12, the water tank 2 is started, so that the water in the water tank 2 flows to the water pipe in the water delivery plate 14 through the water delivery pipe 21, and is sprayed out through the water outlet pipes 22 and the nozzles 23 on the two horizontal plates. The water mist sprayed downward by the nozzles 23 can absorb the dust and debris generated during the discharge, thereby reducing the dust during the discharge.

[0039] When screening, the corundum on the screening plate 32 falls onto the unloading plate 34 under the action of gravity, and falls into different collecting boxes 5 through the discharge port 12 for collection. At the same time, the dust and impurities falling from the screening plate 32 below can be collected through the bottom dust collecting box 13 at the bottom.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
