Description

[Technical field]

[0001] The invention belongs to the technical field of material drying equipment, and specifically refers to a peristaltic propulsion type material conveying device for drying equipment. [Background technology]

[0002] Material drying equipment is widely used in the drying process of chemical, food, pharmaceutical, building materials and other industries. In the field of sludge treatment, the mud cake produced by the sludge dewatering machine, after granulation or strip making, falls freely onto the mesh crawler, and is transported by multiple layers of reciprocating mesh belts. The mud cake on the mesh belt gradually evaporates, and finally forms a material with a lower moisture content for discharge.

[0003] Chinese invention patent 201810369116.0 discloses a return air circulation heating drying device, and Chinese invention patent 201810953665.2 discloses a closed belt dryer. The material conveying devices in these two patent documents both use a conveyor belt to convey materials, wherein the conveyor belt is a mesh belt. The heat source inlet is set below the bottom of the drying chamber, and the discharge port is open.

[0004] This type of drying equipment in the prior art has the following disadvantages: 1. The drying efficiency is extremely low for mud cakes with high moisture content that cannot be formed. 2. After the mud cake falls onto the mesh belt, it cannot be evenly spread in a short period of time, and often piles up together, and even blocks the ventilation mesh of the filter on the mesh belt, affecting the ventilation and evaporation effect. 3. The shape of the mud cake will not change during the transportation process, and the moisture inside the mud cake cannot be discharged. The mud cake at the bottom cannot always be in contact with the hot air during a transportation process, resulting in uneven evaporation. [Summary of the invention]
