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 to 5, a wavy double-layer replaceable vibrating screen comprises an upper frame 1 and a lower frame 2, wherein the upper frame 1 is connected above the lower frame 2 in a staggered manner, the upper frame 1 is fixedly connected to the lower frame 2 through epoxy resin or rubber powder, a # -shaped support bar 9 is arranged on the upper frame 1 to enhance firmness, a plurality of support ribs 10 arranged in parallel are arranged on the lower frame 2, the distance between two adjacent support ribs 10 is equal, and firmness is enhanced through the # -shaped support bar 9 and the support ribs 10.
The upper surface of the upper frame 1 and the lower surface of the lower frame 2 are respectively provided with a wavy upper sieve plate 4 and a wavy lower sieve plate 5 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 repeatedly used, and the sealing rings 8 are utilized to prevent mud from flowing out from gaps between the special mounting nails 3 and sieve plates and prevent mud from damaging a mud pump. 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.
