Technical Field

[0001] The utility model belongs to the technical field of water-coal slurry fine grinding machines, and in particular relates to a novel water-coal slurry fine grinding machine. Background Art

[0002] Coal-water slurry is a slurry fuel made of coal, water and a small amount of chemical additives. Specifically, it is mainly composed of about 65% coal, 34% water and 1% additives. The production process of coal-water slurry includes mixing coal powder with water and adding a certain proportion of dispersants and stabilizers to ensure its fluidity and stability.

[0003] Chinese patent announcement No. CN216368223U discloses a water-coal slurry fine grinder, including a cylinder, a motor, an inspection door, a feed pipe, a discharge pipe, and a tool holder. The motor is vertically installed on the upper end of the cylinder, and an inspection door is installed on the lower right end of the cylinder. A feed pipe is fixed to the lower side of the front end of the cylinder, and the rear side of the feed pipe passes through the cylinder. A discharge pipe is fixed to the upper side of the front end of the cylinder, but the discharge pipe lacks a cleaning device for the internal filter plate, which makes it easy for the filter plate to be blocked when filtering and discharging in the discharge pipe, causing the coal slurry to easily overflow from the shaft seal of the rotating rod main shaft, causing roof caving or main shaft locking accidents. Therefore, a new water-coal slurry fine grinder is needed to solve the above problems. Utility Model Content

The material in the lower layer will continue to be crushed and stirred, thereby realizing the crushing and stirring process of the material.
