Description

Technical Field

[0001] The utility model relates to the technical field of feeders, and more specifically, to a cleaning device for a wet ball mill feeder. Background Art

[0002] Power plants and industrial boilers typically use fossil fuels such as coal and oil. Since these fossil fuels generally contain sulfur, harmful substances such as sulfur dioxide are produced during the combustion process. Limestone-gypsum wet flue gas desulfurization units are widely used in large power plant boilers to remove sulfur dioxide from boiler flue gas. Limestone-gypsum wet flue gas desulfurization units require limestone slurry as an absorbent to absorb sulfur dioxide in the flue gas. Limestone slurry is made by mixing limestone powder of a certain particle size with water, so the preparation of limestone powder is the most important process in slurry preparation. Generally, in the mining and metallurgical fields, there are two systems for the preparation of ore powder and its slurry: dry pulping system and wet pulping system.

[0003] The process flow of a conventional wet pulping system is as follows: after the limestone is initially crushed, it is stored in a high-position limestone silo, and the limestone is fed into a wet ball mill below the limestone silo through a belt feeder at the bottom of the limestone silo for grinding with water. The limestone slurry coming out of the mill enters a limestone slurry tank set on the ground, and is sent to a primary limestone slurry cyclone through a horizontal limestone slurry circulation pump for preliminary screening of the limestone slurry. The slurry mainly containing coarse particles at the bottom of the cyclone returns to the mill for re-grinding, and the slurry above the cyclone is collected in a secondary slurry circulation tank and sent to a secondary limestone slurry cyclone for separation through a secondary horizontal circulation slurry pump. The bottom slurry returns to the mill, and the overflow slurry is stored in a limestone product slurry tank and is pumped to an absorption tower to participate in the desulfurization reaction.

[0004] However, after the feeder is loaded, some residue will be generated inside the feeder, which is not easy to clean. For example, a feeder proposed in announcement No. CN220033177U includes a transmission box, an auger and a hopper detachably arranged on the transmission box, and a fastening bolt. The hopper includes a feeding part, a twisting part arranged at the bottom of the feeding part, a discharge part arranged at one end of the twisting part away from the feeding part, and a connecting plate connected between the feeding part and the twisting part, and the connecting plate is located at the end of the feeding part and the twisting part away from the discharge part. The auger extends into the twisting part, and one end of the fastening bolt passes through the connecting plate and is threadedly connected to the transmission box. The feeder of the utility model uses fastening bolts to connect the connecting plate with the transmission box through threads, so that the hopper and the transmission box can be connected at the same time, and the auger is clamped on the transmission box and is not easy to separate. Therefore, when the feeder is disassembled, the hopper and the auger are separated from the transmission box together. Even if there is residual material in the hopper, it will not cause the residual material to be scattered on the site. However, the internal residue is still difficult to clean and the workload is large. Therefore, a wet ball mill feeder cleaning device is proposed. Utility Model Content
