Device for blending pulverized fuel ash and cement

Abstract

The invention relates to a device for blending pulverized fuel ash and cement. The device for blending pulverized fuel ash and cement comprises a metering tank, a primary mixing tank, a batch mixing tank, a dust removing tank, dust removers, a fan, a pulverized fuel ash tank, a cement tank, a fished product bin, a pressure air tank, pneumatic adjusting valves, a sampling ball valve, a stop valve and a safety valve, wherein the pressure air tank is connected with the bottoms and lateral portions of the metering tank, the primary mixing tank and the batch mixing tank; the pulverized fuel ash tank is connected with the bottom of the metering tank, the bottom of the cement tank and the bottom of the metering tank are connected with the bottom of the primary mixing tank, and the bottom of the finished product bin and the bottom of the primary mixing tank are connected with the bottom of the batch mixing tank; the top of the metering tank, the top of the primary mixing tank and the top of the batch mixing tank are each connected with one dust remover and then connected with the top of the dust removing tank, and the top of the dust removing tank is connected with the fan; and pipeline connection is used as the connection mode. By means of the device for blending pulverized fuel ash and cement, the problem that pulverized fuel ash and cement are not mixed evenly is solved.

Description

technical field [0001] The invention belongs to the field of mixing fly ash and cement, in particular to a device for mixing fly ash and cement. Background technique [0002] As for the products mixed with fly ash and cement, there are also some finished products that have been produced and sold at home and abroad, and have been applied in some decommissioning projects. [0003] Internationally, the design, processing and manufacturing technology of large-scale mixing of fly ash and cement is mainly derived from the solidification of large-volume pouring of medium-level radioactive waste liquid in the United States. Its mixing process is a commercial technology secret, and the specific parameters are unknown. [0004] In China, there is no special fly ash mixing technology with independent intellectual property rights, and there are no relevant national standards or industry standards. The mixing device used in the project is reusable. The initial investment is relatively...
