Description

Technical Field

[0001] The utility model relates to the technical field of mud cake conveying, in particular to a mud cake conveying system. Background Art

[0002] Filter press mud cake refers to a solid substance produced in the filter press process, which is a piece of solid substance formed by squeezing out solid particles in the suspended liquid by the filter press. Filter press mud cake has high dryness, consistency and hardness, and usually has good physical and chemical stability. Filter press mud cake is particularly widely used in environmental protection, mining, chemical industry, food manufacturing and other fields. Since the water content of the mud cake is low after filtration, the shape and hardness of the mud cake are relatively fixed. When the mud cake needs to be recycled, the mud cake needs to be effectively crushed and used. Prior art, such as the patent with announcement number "CN115959492 A", proposes a mud cake conveying matching system, including a conveyor, a transfer bucket and a crushing head, wherein the conveyor has a conveying space, and has an inlet and an outlet connected to the conveying space, the inlet is used to be installed below the filter press; the transfer bucket is installed below the outlet; the crushing head is rotatably installed in the conveying space, which solves the current technical problem that the mud cake formed after the mud is pressed is not convenient for transportation. Prior art, for example, the patent with announcement number "CN 110052065A" proposes a conveying device for the mud cake discharged from a plate and frame filter press. A grid is added below the mud bucket. The grid has a great destructive force on the mud cake. Under the action of gravity, the mud cake is divided into small pieces with smaller particle sizes through the grid for easy transportation. The above two patents both solve the problem that the mud cake is too large and hard to be transported. However, during the transportation process of the first patent, the mud cake is easily stuck in the spiral blade and cannot be removed. In the second patent, since the mud cake is continuously falling, the amount of mud cake passing through the grid is limited, and the mud cake is easily accumulated on the grid to cause blockage.
