Description

Technical Field

[0001] The utility model relates to the technical field of sodium silicate production, in particular to a raw material screening device for sodium silicate production. Background Art

[0002] Commonly known as sodium silicate, it is a water-soluble silicate. Its aqueous solution is commonly known as water glass, which is a mineral adhesive. Sodium silicate needs to be crushed during production, and a ball mill is usually used for crushing.

[0003] After searching, it was found that the announcement number is CN218690065U, and the name is a high-efficiency ball mill for preparing sodium silicate powder. The application proposes that the existing ball mill for preparing sodium silicate powder cannot be screened synchronously after the powder is discharged after crushing and grinding, and the powder will be mixed with large particles of insufficiently ground materials, which will not only affect the quality of the sodium silicate powder, but also reduce the working efficiency of grinding. The driving motor drives the rotating rod to rotate, and the rotating rod drives the eccentric wheel to rotate. The rotation of the eccentric wheel can squeeze the first mounting frame and the second mounting frame up and down. In conjunction with the setting of the first damping rod and the second damping rod, the first screening plate and the second screening plate will vibrate, and the steel balls and the powder are screened respectively. The first screening plate and the second screening plate are easy to install and disassemble, so as to facilitate the screening of the ground materials and improve the working efficiency of grinding. However, when the application is actually used, the raw materials staying on the top surface of the screening plate need to be removed by the staff to clean the screening plate. Frequent disassembly and cleaning are very troublesome, affecting the working efficiency and wasting labor. Further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

As Figures 1-4 shown, the raw material screening device for sodium silicate production according to an embodiment of the present utility model includes a bottom box 1 and a top ring 2. The top surface of the bottom box 1 is fixedly connected to the top ring 2 through a support rod 12, and insertion rings 6 are integrally connected to the top surfaces of both the top ring 2 and the bottom box 1. Moreover, a first screening plate 4 and a second screening plate 7 are respectively rotatably connected to the inner sides of the top openings of the top ring 2 and the bottom box 1 outside the insertion rings 6. The first screening plate 4 and the second screening plate 7 have the same vertical cross-sectional dimensions and are both in a disc-shaped structure. A servo motor 11 is fixedly installed on the bottom surface of the bottom box 1, and a shaft rod 10 is installed at the output end of the servo motor 11. Moreover, the shaft rod 10 is fixedly connected to the second screening plate 7 and the first screening plate 4 respectively. First screening holes 5 and second screening holes 8 are respectively formed on the surfaces of the first screening plate 4 and the second screening plate 7, which play a role in multiple screenings. The purpose of arranging the second screening plate 7 is to reduce the screening pressure on the first screening plate 4 and avoid material accumulation from reducing the screening efficiency. When screening the crushed sodium silicate raw materials, the staff can put the crushed sodium silicate raw materials into the first screening plate 4. The servo motor 11 drives the shaft rod 10 to rotate in a small-angle reciprocating manner, so that the sodium silicate raw materials in the first screening plate 4 shake for screening. The raw materials with a particle size smaller than the first screening holes 5 enter the second screening plate 7, and the second screening plate 7 simultaneously rotates in a small-angle reciprocating manner to continue screening the raw materials, completing multi-stage screening. After the screening is completed, the staff can start the servo motor 11 to drive the shaft rod 10 to rotate at a high speed, thereby driving the first screening plate 4 and the second screening plate 7 to rotate at a high speed, and the large-particle raw materials remaining inside the first screening plate 4 and the second screening plate 7 are thrown out by centrifugal force, completing automatic cleaning, saving the trouble of manual disassembly and cleaning, and improving the convenience of use.

[0031] In one embodiment, ring seats 9 are fixedly connected to the top edges of the top surfaces of the first screening plate 4 and the second screening plate 7. The top ring 2 is inserted into the inner side of the ring seat 9 and is rotationally connected to the ring seat 9 through a bearing. The insertion ring 6 extends into the ring seat 9 to limit and guide the ring seat 9. When the servo motor 11 performs screening, it shakes and screens the raw materials through small-angle reciprocating rotation, which produces less noise and operates more stably compared with traditional vibration screening, improving the convenience of use and work efficiency.

[0032] In one embodiment, the aperture of the first screening holes 5 is larger than that of the second screening holes 8, and both the first screening holes 5 and the second screening holes 8 are densely and evenly distributed, which is a common screening structure and will not be elaborated here.

[0033] In one embodiment, multiple support rods 12 are arranged at equal angles, and the support rods 12 are made of metal round rods that are not easily deformed. The support rods 12 have little problem of blocking the thrown raw materials, avoiding affecting the cleaning and discharging.

[0034] In one embodiment, the shaft rod 10, the first screening plate 4, the second screening plate 7, the top ring 2 and the bottom box 1 are coaxially arranged, and the shaft rod 10 is rotationally connected to the bottom box 1 through a bearing. The shaft rod 10 penetrates through the second screening plate 7 and is fixedly connected to the second screening plate 7, and the top surface of the shaft rod 10 is fixedly connected to the center position of the bottom surface of the first screening plate 4.

[0035] In one embodiment, a discharge port 14 is opened on the bottom surface of one end of the bottom box 1, and the bottom surface of the bottom box 1 is an inclined surface. The bottom box 1 facilitates the raw materials to gather and flow out through the discharge port 14 for collection, and legs 13 are fixedly installed on the bottom surface of the bottom box 1 for convenient placement.

[0036] In one embodiment, the inner wall of the first screening plate 4 is polished, and the top openings of the first screening plate 4 and the second screening plate 7 are flush with the top surface of the ring seat 9, facilitating the large-particle raw materials to slide outward and move out of the first screening plate 4 and the second screening plate 7.

[0037] In one embodiment, slopes 3 are opened on the top surface of the bottom box 1 and the top surface of the top ring 2, and the top of the slope 3 is flush with the top surface of the ring seat 9. The slopes 3 facilitate the large-particle raw materials to slide out of the bottom box 1 and the top ring 2.

[0038] Working principle:

[0039] When screening the crushed sodium silicate raw material, the staff can put the crushed sodium silicate raw material into the first screening tray 4. The servo motor 11 drives the shaft rod 10 to rotate reciprocally at a small angle, so that the sodium silicate raw material in the first screening tray 4 shakes for screening. The raw material with a particle size smaller than the first screening hole 5 enters the second screening tray 7, and the second screening tray 7 rotates reciprocally at a small angle synchronously to continue screening the raw material, completing multi-stage screening. After the screening is completed, the staff can start the servo motor 11 to drive the shaft rod 10 to rotate at high speed, and then drive the first screening tray 4 and the second screening tray 7 to rotate at high speed, and use centrifugal force to throw out the large-particle raw materials remaining inside the first screening tray 4 and the second screening tray 7, completing automatic cleaning, saving the trouble of manual disassembly and cleaning, and improving the convenience of use.
