Description

Horizontal sand mill for processing water-based paint Technical Field The utility model relates to the field of sand mills, in particular to a horizontal sand mill for processing water-based paint. Background Any coating that uses water as a solvent or as a dispersion medium may be referred to as an aqueous coating. According to the kind of binders in the paint, the aqueous paint is classified into two main kinds, namely, natural aqueous paint of natural substances or minerals and petrochemical aqueous paint of artificial synthetic resin. In the production of the aqueous paint, it is necessary to grind the aqueous paint, and therefore, it is necessary to use a horizontal sand mill for the aqueous paint. For example, the patent with the publication number of CN222855584U discloses a cooling mechanism of a horizontal sand mill, which relates to the technical field of cooling mechanisms and comprises a machine table, wherein a mounting plate is fixedly arranged on the top surface of the machine table. According to the utility model, cooling water is introduced into the cooling pipe, so that heat of the grinding cylinder body can be effectively taken away, temperature control in the grinding process is ensured, grinding effect and product quality are prevented from being influenced due to overhigh temperature, a water source entering the cooling pipe can be filtered by the filter screen, large-particle impurities and foreign matters are prevented from entering the cooling pipe, the possibility of blockage and damage is reduced, the service life of the cooling pipe is prolonged, meanwhile, a worker can easily complete the replacement of the filter screen by designing a convenient filter screen replacement mechanism, complex operation is avoided, maintenance efficiency is improved, equipment downtime is reduced, the filter screen can be quickly replaced when the filter screen is blocked or damaged, continuous and stable operation of a cooling system is ensured, and equipment faults or shutdown caused by cooling failure are avoided.
