Preparation device for coal water slurry additive

Abstract

The invention discloses a preparation device for a coal water slurry additive. The preparation device comprises a drying box body, wherein a first feeding funnel is arranged at the top end of the drying box body, a first conveying mechanism, a second conveying mechanism and a third conveying mechanism are arranged in the inner cavity of the drying box body, and a grinding mechanism is arranged between the discharging end of the first conveying mechanism and the feeding end of the second conveying mechanism; and the grinding mechanism is composed of a first material collecting bin, an inclined material guiding plate, a vibration filtering net sieve, a grinding roller and a rotating motor, wherein a heating plate is arranged on the inner side end wall of the drying box body, a gas filtering box body is arranged on the outer side end wall of the drying box body, a filter frame, a screw rod, a movable frame and a water absorption layer are arranged in the filter box body, an air supply box body is arranged at the bottom of the outer side of the drying box body, and an air supply fan is arranged in the air supply box body.

Description

technical field [0001] The invention relates to the field of coal-water slurry additives, in particular to a preparation device for coal-water slurry additives. Background technique [0002] The drying process in the preparation process of coal-water slurry additives is related to its storage quality in the later stage. The existing drying equipment for coal-water slurry additives generally adopts airflow drying, and uses manual stacking and drying. If the materials are piled up into agglomerates, it will cause Insufficient drying of internal materials and low drying efficiency affect the quality of CWS additives; the high-heat gas in the drying equipment for CWS additives is directly discharged, which will not only make the operating environment of the equipment hot and humid, but also cause heat energy A large amount of waste; CWS additives need to be ground and screened for particle size in the preparation process. The grinding and screening is usually carried out with sp...

[0002] The drying process in the preparation process of coal-water slurry additives is related to its storage quality in the later stage. The existing drying equipment for coal-water slurry additives generally adopts airflow drying, and uses manual stacking and drying. If the materials are piled up into agglomerates, it will cause Insufficient drying of internal materials and low drying efficiency affect the quality of CWS additives; the high-heat gas in the drying equipment for CWS additives is directly discharged, which will not only make the operating environment of the equipment hot and humid, but also cause heat energy A large amount of waste; CWS additives need to be ground and screened for particle size in the preparation process. The grinding and screening is usually carried out with special equipment, which not only has a cumbersome process, increases the production cost, but also increases the processing time and reduces production efficiency; After the coal water slurry additive is dried, it is inevitable that a small amount of material will adhere to the drying shelf, which will not only cause material loss, but also interfere with the subsequent preparation of the additive. Therefore, a coal water slurry additive is now needed Preparation device
