Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-4, a high-efficiency replaceable double-layer slurry vibrating screen comprises an upper frame 1 and a lower frame 2, wherein the upper frame 1 is fixedly connected above the lower frame 2 through epoxy resin or rubber powder in a staggered manner, a # -shaped support rod is arranged on the upper frame 1, a plurality of support ribs arranged in parallel are arranged on the lower frame 2, and the distance between every two adjacent support ribs is equal.
The upper screen plate 4 and the lower screen plate 5 are mounted on the upper surface of the upper frame 1 and the lower surface of the lower frame 2 through special mounting nails 3, sealing rings 8 are arranged between the special mounting nails 3 and the upper frame 1 and the lower frame 2, the sealing rings 8 can be used repeatedly, and mud is prevented from flowing out from gaps between the special mounting nails 3 and the screen plates by the aid of the sealing rings 8, so that the mud pump is prevented from being damaged by the mud. When the sieve plate is disassembled, the special mounting nails 3 are pulled out, then the sieve plate is replaced, the rivets are nailed again, the replacement is more convenient, and the cost is saved.
And the upper sieve plate 4 and the lower sieve plate 5 are both provided with three layers of screen meshes 7, and the screen meshes 7 are bonded on the upper sieve plate 4 and the lower sieve plate 5 through epoxy resin. The material of the screen 7 is 304, 316 or 316L stainless steel net, which is selected according to the requirement.
The screen cloth 7 on the upper screen plate 4 is a coarse screen cloth, the screen cloth on the lower screen plate 5 is a fine screen cloth, mud is filtered by the coarse screen cloth and then is directly filtered by the fine screen cloth through the screen cloth 7 with different diameters, the workload of workers is reduced, the working efficiency is improved, and the screen cloth 7 on the upper screen plate 4 and the screen cloth 7 on the lower screen plate 5 are staggered due to the fact that the upper frame 1 and the lower frame 2 are staggered, and vertical shunting is achieved.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
