Description

Technical Field

[0001] The utility model relates to the technical field of drying agent drying equipment, in particular to a sludge drying agent rapid drying equipment. Background Art

[0002] Sludge drying is one of the most common sludge treatment methods. In addition to rapid stirring and other methods, the drying process also requires the addition of sludge drying agents to further reduce the moisture content of the dried sludge product. Drying treatment is required during the sludge drying agent processing process.

[0003] The prior art discloses a rapid sludge drying device with application number 202221481438.2, comprising a drying device, a hot air blower, an exhaust gas filter box, and support legs. The hot air blower is detachably connected to the left outer surface of the drying device, the exhaust gas filter box is detachably connected to the right outer surface of the drying device, and the support legs are fixedly mounted on the bottom outer surface of the drying device. The utility model starts an exhaust fan and uses the exhaust fan in conjunction with a ventilation duct to draw the water vapor, odor, and harmful gases generated during the drying process inside the drying device into the exhaust gas filter box through the ventilation duct, and then passes through the exhaust gas filter element for filtration and is discharged from the air outlet. This solves the problem that traditional sludge drying equipment does not have an exhaust gas filtering and collecting device, which easily causes the exhaust gas generated during the sludge drying process to be emitted, thereby affecting the health of the staff, so as to achieve the effect of filtering the exhaust gas before discharge. However, the drying method is single, which makes the material drying efficiency low. Utility Model Content
