Description

Technical Field

[0001] The utility model belongs to the technical field of acrylic resin production, and specifically relates to a wet sand mill for acrylic resin production. Background Art

[0002] In the production and processing of acrylic resin coatings, a grinding device is required to wet-grind the acrylic resin raw materials. The horizontal sand mill is one of the commonly used grinding devices. It uses a material pump to input the solid-liquid phase mixture that has been pre-dispersed and wetted by the mixer into the cylinder. The material and the grinding medium in the cylinder are stirred by the high-speed rotating disperser, so that the solid particles in the material and the grinding medium produce stronger collision, friction, and shearing effects with each other, so as to accelerate the grinding of particles and disperse aggregates. In the production process, the material will be mixed with a large amount of fine iron impurities when entering the sand mill, so it is often treated with iron removal before processing. At present, a magnetic ring is usually set on the inner wall of the feed pipe to adsorb iron impurities, and the material passes through the hollow part of the magnetic ring. When feeding, the magnetic ring adsorbs the iron impurities in the material to achieve the purpose of impurity removal.

[0003] However, since the adsorption force on the fine iron impurities contained in the material passing through the inner part of the feed pipe near the central axis is weak, some fine iron impurities are not easily adsorbed by the magnetic ring and are missed. Therefore, the single-channel magnetic ring adsorption structure is not suitable for effectively adsorbing iron on long and thick feed pipes, while the simple arrangement of multiple magnetic ring adsorption structures will cause difficulties in disassembly and assembly and affect the efficiency of material passage.

[0004] Therefore, a wet sand mill for acrylic resin production is needed to solve the problems in the prior art that some fine iron impurities are not easily adsorbed by the magnetic ring and are missed, and the existing magnetic attraction structure is not well adaptable to long and thick feed pipes.
