High sludge drying dehydration device and using method thereof

Abstract

The invention discloses a high sludge drying dehydration device which comprises a bracket, a rotating shaft, a filter pressing component, a rotating motor, a transverse hydraulic cylinder, a drainagepipe, a cleaning component and a sludge storage component, wherein the filter pressing component comprises a plurality of filter pressing plates, a plurality of filter bags, a filter pressing frame, shaft levers, calipers and a longitudinal hydraulic cylinder; the filter pressing plates and the filter bags are arranged at intervals; perforations are formed in the bottoms of the filter pressing plates; the shaft levers penetrate through the perforations; locking units are arranged on the side faces at the upper ends of the filter pressing plates; the locking units comprise bolt columns and concave holes; clamping grooves are formed in the tops of the filter pressing plates; the calipers are connected into the clamping grooves; pressure levers are fixedly connected to the upper end of the calipers; two ends of the pressure levers are fixedly connected with the longitudinal hydraulic cylinder; feeding holes are formed in the middles of the filter pressing plates; drainage holes are formedin the lower ends of the filter pressing plates and correspond to the drainage pipe. The using method of the equipment comprises the following steps: feeding, filter pressing, mud cake discharging and filter bag cleaning. The equipment is convenient to use, the operating cost is low, and industrialization is easily realized.

Description

technical field [0001] The invention relates to a high-dry sludge dehydration device and a use method thereof, belonging to the technical field of sewage sludge treatment. Background technique [0002] With the increasing emphasis on sewage treatment in various countries and the continuous construction of urban sewage treatment plants, the output of sludge continues to increase, and the rapid and effective treatment of sludge is urgent. Sludge has the characteristics of high water content, harmful organisms such as a large number of pathogens and microorganisms, and high content of heavy metals and organic matter. If it is not treated before discharge, it will cause secondary pollution to the environment. The principle of sludge treatment is to realize the reduction, stabilization, harmlessness and recycling of sludge. Among them, sludge reduction is undoubtedly the key to subsequent sludge treatment and the focus of sludge disposal. There are two ways to reduce sludge, one...
