Solid liquid high-efficiency separation device for filter mud of sugar refinery

Abstract

The invention relates to a solid liquid high-efficiency separation device for filter mud of a sugar refinery and belongs to a solid liquid separation device. The device comprises a conveying belt, a mud separating hopper, a double-wheel roller, a mud water separator, a mud block chopper, a screw extruder, a mud strip scraping device, a spiral conveyer with a heating component and a dry mud crusher which are driven to operate by a transmission device, wherein the conveying belt is arranged above the mud separating hopper; the mud separating hopper is arranged above the double-wheel roller; the mud water separator is arranged below the double-wheel roller; the mud block chopper is arranged between the mud water separator and the screw extruder; the mud strip scraping device is arranged at the outlet end of the screw extruder; the spiral conveyer is arranged below the screw extruder; the heating component is arranged on a shell; and the dry mud crusher and a bagging mechanism are arranged below the spiral conveyer. The device repeatedly extrudes wet filter mud, dries, crushes, separates sugar-containing water from the filter mud, prepares dry mud powder into fertilizer powder or building materials, and is energy-saving in dehydration and deodorization of the wet filter mud.

Description

technical field [0001] The invention relates to a solid-liquid separation device, in particular to a high-efficiency solid-liquid separation device for filter mud in a sugar factory. Background technique [0002] So far, there are more than 100 sugar-making enterprises in my country, with an annual sugar output of about 13 million tons. In 2010, the sales revenue of sugar products in the whole industry was about 91 billion yuan. About 3.5 million tons of filter mud are produced in the sugar industry every year. Calculated according to the proportion of sugar content in the water in the filter mud, about 350,000 tons of sugar are lost, and the total value of the loss is 2.45 billion yuan. In these sugar-making enterprises, more than 90% use non-filter cloth suction filter to process the sugar-making waste residue. The filter mud processed by the suction filter contains 60-70% water and about 10% sugar. The sugar in the filter mud will ferment, which will make the filter mud...

AI Technical Summary

Problems solved by technology

If a large amount of sugary water in the filter mud is not removed, the above method still cannot be implemented; if the common drying method is used to remove the sugary water in the filter mud, its energy consumption and cost are considerable, even unaffordable to producers
