A feeding device for sludge drying equipment

Abstract

The invention discloses a feeding device of sludge drying equipment. The feeding device comprises a sludge feeding end, a feeding buffer and storage device, a quantitative feeder, a squeezing machine and an automatic control device. The feeding device has the advantages that the feeding device is provided with the feeding buffer and storage device, and sludge can be delivered to sludge quantitative distributors in the quantitative feeder by a sludge distribution opening and can be intermediately stored and quantitatively fed; the feeding device is provided with the quantitative feeder, so that the sludge can be turned into sludge cakes, the sludge cakes can be fed into the squeezing machine at certain intervals, the quantitative feeding speeds can be changed, and production of the sludge drying equipment can be adjusted; the feeding device is provided with the squeezing machine, and the sludge cakes which are quantitatively fed into the squeezing machine can be squeezed to obtain sludge strips, so that materials are consistent in piling height, the porosity can be improved, the contact area of the sludge and hot air can be enlarged after the sludge is fed into the sludge drying equipment, flow resistance on the hot air in drying procedures can be reduced, and drying effects and the drying efficiency can be improved after the sludge is fed into the sludge drying equipment; the feeding device is simple in structure, convenient to operate and high in automation degree.

Description

Technical field: [0001] The invention belongs to the technical field of sludge treatment equipment, and in particular relates to a feeding device of sludge drying equipment. Background technique: [0002] At present, sludge disposal in large cities has become difficult and expensive, long-distance sludge haulage, fuel and transportation costs have increased, sludge landfills consume a lot of land resources, and costs have increased, wet sludge direct incineration is expensive, and because Due to problems such as smog, citizens opposed the construction of incinerators in the city. Thermal drying of sludge is a safe, reliable, fast, efficient and large-scale sludge reduction technology. Sludge drying refers to the process of removing most of the water content from sludge through percolation or evaporation. After the sludge is thermally dried, the following effects can be achieved: the sludge is dried from 25% DS to 90% DS, the weight is reduced by about 78%, the product is ea...
