Description

Technical Field

[0001] The utility model belongs to the technical field of sludge drying machines, in particular to a sludge drying machine capable of preventing sludge accumulation. Background Art

[0002] Sludge drying, also known as sludge dehydration, refers to the process of removing most of the water in the sludge through filtration or evaporation. Sludge dryers are generally used. After the sludge is concentrated, physical methods are used to further reduce the water content of the sludge to facilitate the transportation, accumulation, utilization or further treatment of the sludge. There are two types of dehydration: natural evaporation and mechanical dehydration.

[0003] After searching, the patent with publication number CN115259620A discloses a sludge low-temperature belt dryer with stable drying performance, including a drying box, a crushing mechanism is fixedly installed on the top of the feeding port of the drying box, the top of the crushing mechanism is fixedly connected with the feeding port, the first spiral roller and the second spiral roller are movably sleeved inside the crushing mechanism, and stainless steel mesh belt conveyor 1 and stainless steel mesh belt conveyor 2 are installed inside the drying box. The sludge low-temperature belt dryer with stable drying performance, through the coordinated use of the dividing block and the dividing plate, uses the dividing block to separate the sludge discharged from the crushing mechanism into two parts, and then the triangular teeth at the bottom of the dividing plate further separate the two parts of sludge, so that the sludge can be more evenly distributed on the top of the stainless steel mesh belt conveyor 1.

[0004] However, since the sludge contains a large amount of water and colloidal substances, these substances easily form a network structure, causing the sludge particles to stick to each other to form clumps, thereby causing the sludge to lose fluidity and easily coagulate. In the above patent, after the sludge enters the inner side of the triangular teeth at the bottom of the dividing plate, it is easy to adhere to the inside of the dividing plate and accumulate in clumps, which can easily cause blockage inside the dryer.
