Granulator for producing ceramsites by using municipal sludge

Abstract

The invention discloses a granulator for producing ceramsites by using municipal sludge. The granulator comprises a production box body; a stirring chamber is arranged in the production box body; thelower side of the stirring chamber is provided with an extrusion chamber; a stirring blade capable of stirring and mixing sludge and other additives is arranged in the stirring chamber; a closed platecan be opened by rotating a rotating rod, so that raw materials in the stirring chamber are sampled; when the raw materials in the stirring chamber is relatively dried, water is introduced to a waterinjection pipe to humidify the raw materials in the stirring chamber, so that the sludge and other raw materials can be mixed, and a great deal of working time can be saved; the mixed raw materials can be subjected to sampling inspection during mixing treatment, and the water can be sprayed into the stirring chamber, so that the viscosity of the raw materials is increased; when the ceramsites areproduced by using the granulator, the sizes of particles are regulated, in this way, the ceramsites can be directly delivered after being produced so as to be prevented from being adhered to each other.

Description

technical field [0001] The invention relates to the field of sludge treatment, in particular to a granulator for producing ceramsite by using urban sludge. Background technique [0002] When cleaning the rivers in some cities and towns, the main treatment object is the sludge in the river. At present, when sludge is treated, the sludge is generally treated as fertilizer, and the sludge can also be used Make ceramsite. [0003] When using sludge to make ceramsite, the raw materials used are different from those used in traditional ceramsite. When ceramsite is granulated, the added granulated raw materials are mixed by other mixing equipment and then transferred over for production. It is easy to waste a lot of time when working with ceramsite, and the work efficiency is low. When the raw materials are mixed, the effect of the mixed raw materials cannot be checked by sampling. When the ceramsite is granulated, it is impossible to control the granules made. The size of the ce...

Problems solved by technology

[0003] When using sludge to make ceramsite, the raw materials used are different from those used in traditional ceramsite. When ceramsite is granulated, the added granulated raw materials are mixed by other mixing equipment and then transferred over for production. It is easy to waste a lot of time when working with ceramsite, and the work efficiency is low. When the raw materials are mixed, the effect of the mixed raw materials cannot be checked by sampling. When the ceramsite is granulated, it is impossible to control the granules made. The size of the ceramsite is controlled. After some ceramsite particles are made, because they are not calcined, they are bonded together after falling together, and the ceramsite particles are not separated.
