The rubber gasket 24 and the rubber ring 22 cooperate with the pressing groove 11 to effectively reduce the vibration of the screen 3, thereby preventing the screen 3 from being damaged and improving the use efficiency of the screen 3; the rubber gasket 24 and the rubber ring 22 have a certain elasticity, which reduces the vibration of the screen 3, thereby reducing the collision between the screen 3 and the upper frame 1 and the lower frame 2 of the vibrating screen, thereby reducing the damage rate of the screen 3 and improving the service life of the screen 3.

[0031] Specifically, the rubber ring 22 and the rubber gasket 24 are both annular and can undergo elastic deformation. The rubber ring 22 and the rubber gasket 24 are used to reduce the vibration of the screen 3. When the upper frame 1 of the vibrating screen cooperates with the lower frame 2 of the vibrating screen, the top wall of the pressure groove 11 of the upper frame 1 of the vibrating screen is held on the surface of the screen 3, so that the screen 3 squeezes the rubber ring 22 and the rubber gasket 24, causing the rubber ring 22 and the rubber gasket 24 to deform. When the upper frame 1 of the vibrating screen and the lower frame 2 of the vibrating screen vibrate to screen the ceramic slurry poured into the upper frame 1 of the vibrating screen, the screen 3 also vibrates with the upper frame 1 and the lower frame 2 of the vibrating screen, and at the same time, the rubber ring 22 and the rubber gasket 24 are used to reduce vibration, thereby reducing the collision and friction between the screen 3 and the upper frame 1 and the lower frame 2 of the vibrating screen.

[0032] In one embodiment of the present application, the upper frame 1 of the vibrating screen and the lower frame 2 of the vibrating screen are connected by bolts. The upper frame 1 of the vibrating screen and the lower frame 2 of the vibrating screen can be fixed by the bolts, while reducing the relative vibration between the two.

[0033] In this application, an embodiment is shown in the attached Figure 4 As shown, a first step groove is provided on the outer side of the annular protrusion 21, the rubber gasket 24 is located in the first step groove, the inner side wall of the screen 3 is in contact with the side wall of the first step groove, and the bottom wall of the screen 3 is in contact with the rubber gasket 24 on the first step groove; the annular protrusion 21 is provided to facilitate the fixing of the screen 3.

[0034] In this application, an embodiment is shown in the attached Figure 5 As shown, the screen 3 includes a plane screen 31 and an annular screen 32. The plane screen 31 is arranged on the surface of the rubber ring 22, and the side of the plane screen 31 away from the rubber ring 22 abuts against the top wall of the pressure groove 11, and the plane screen 31 is fixed by the pressure groove 11 and the rubber ring 22. The annular screen 32 is vertically arranged at the bottom of the plane screen 31, and the annular screen 32 is coaxially arranged with the annular protrusion 21. The inner wall of the annular screen 32 cooperates with the outer wall of the annular protrusion 21 to prevent the plane screen 31 from deflecting, thereby forming a gap so that the screened mud falls directly into the lower frame 2 of the vibrating screen, and the bottom wall of the annular screen 32 abuts against the rubber gasket 24 to reduce the vibration and friction between the annular screen 32 and the lower frame 2 of the vibrating screen.

[0035] In this embodiment, both the flat screen 31 and the annular screen 32 are provided with screen holes.

[0036] In this embodiment, two hoops 4 are provided on the outer surface of the annular screen 32 for fixing the annular screen 32 on the side wall of the annular protrusion 21, so as to prevent the annular screen 32 from shaking; by providing the hoops 4, the screen 3 can be further prevented from vibrating.

[0037] In one embodiment of the present application, a fixing ring 23 is provided on the inner side of the annular protrusion 21, and the fixing ring 23 extends toward the middle along the inner wall of the annular protrusion 21. An annular groove is provided on one side of the rubber ring 22, and the annular groove cooperates with the fixing ring 23 so that the rubber ring 22 is sleeved on the annular protrusion 21. The top of the rubber ring 22 can be used to cover the top wall of the annular protrusion 21, and the rubber ring 22 is in contact with the screen 3 to avoid direct contact between the screen 3 and the annular protrusion 21, thereby causing the screen 3 to be worn or damaged.

[0038] In this embodiment, the fixing ring 23 may not be provided on the inner side of the annular protrusion 21, and the annular groove of the rubber ring 22 is sleeved on the top of the annular protrusion 21, that is, the opening of the rubber ring 22 faces the annular protrusion 21, and the end of the rubber ring 22 away from the annular protrusion 21 is in contact with the screen 3.

[0040] In this application, an embodiment is shown in the attached Figure 3 As shown, a supporting boss 28 is further provided inside the lower frame 2 of the vibrating screen, and the upper surface of the supporting boss 28 is in the same horizontal plane as the upper surface of the rubber ring 22; when the screen 3 is arranged on the upper part of the rubber ring 22, the supporting boss 28 is also in contact with the bottom wall of the screen 3, and is used to support the screen 3 to prevent the screen 3 from being deformed due to the heavy mud, resulting in damage to the screen 3.

[0041] In one embodiment of the present application, a slag outlet 12 is provided on one side of the upper frame 1 of the vibrating screen; impurities in the slurry inside the upper frame 1 of the vibrating screen that have not passed through the screen 3 can be discharged through the slag outlet 12 to prevent clogging of the sieve holes of the screen 3.

[0042] Specifically, the mud is poured into the upper frame 1 of the vibrating screen manually or with auxiliary equipment, and then the vibration motor 27 is started. The vibration motor 27 drives the upper frame 1 and the lower frame 2 of the vibrating screen to vibrate, so that the mud inside the upper frame 1 of the vibrating screen shakes and flows through the screen 3 to the collecting tank of the lower frame 2 of the vibrating screen. The mud or impurities that have not passed through the screen 3 can be discharged through the slag outlet 12, and the mud that flows into the collecting tank 25 can be discharged from the slurry outlet 26 through the connecting pipe until all the mud is screened and the vibration motor 27 stops working.
