Description
TECHNICAL FIELD
[0001] The utility model relates to coal washing processing technical field, especially is wet sticky material buffer even mixes device. BACKGROUND
[0002] Now the coal preparation plant widely uses filter press for coal slime dewatering. When the filter press is discharged, the filter plate is pulled open, the material is separated from the filter plate and directly falls into the scraper machine below through the machine under the chute, and then all the coal slime is directly transported to the product system by the scraper machine in a short time. A working cycle of the filter press is 20-30 min, and the discharge time is only 3-5 min. The moisture content of the coal slime after filtration is 20-28%.
[0003] The fine coal slime dewatering equipment of the coal preparation plant mostly adopts a quick-opening diaphragm filter press. The equipment is an intermittent working device. The main feature of the discharge is that the discharge is concentrated in a short time. The filtered coal slime is composed of very fine particles, has high moisture content and high viscosity. If the coal slime is evenly mixed into the coal product, the influence on the product quality is small. However, since the filter press is an intermittent working device, the coal slime is mixed into the coal product in a short time, which causes the product quality to be uneven, the local moisture content to be high, the ash content to be high, and the viscosity to be large. After being stored in the warehouse, the coal is prone to be bonded and difficult to be discharged. After being stored in the coal yard, the coal is prone to be frozen into blocks in winter, which causes many problems in loading and transportation. UTILITY MODEL CONTENTS
