A coating sand mill for producing environmentally friendly low-carbon coatings

Abstract

The invention belongs to the technical field of coating production equipment, and in particular relates to a coating sand mill for producing environmentally friendly low-carbon coatings. The interior of the chamber is provided with a drainage impeller, and the drainage impeller is fixedly sleeved on the output end of the motor. A sand grinding cylinder is arranged under the cold water chamber, and a plurality of grinding sheets are fixedly connected to the side of the output end of the motor. The outer side of the grinding cylinder is covered with a cooling outer partition, and a water-passing cooling layer is provided between the cooling outer partition and the sand grinding cylinder. The upper end of the water-passing cooling layer communicates with the lower side of the cold water chamber, and the sand The bottom of the grinding cylinder is provided with a plurality of sieve holes which are distributed circularly with the output end of the motor as the center, the sieve holes are provided with a screen, and the lower end of the sand grinding cylinder is provided with a material storage chamber. The invention can greatly save cooling water, and at the same time ensure the cooling effect of the sand mill cylinder.

Description

technical field [0001] The invention belongs to the technical field of paint production equipment, in particular to a paint sand mill for producing environmentally friendly low-carbon paint. Background technique [0002] The paint sand mill is a processing equipment for stirring and grinding the paint during the paint production process. The currently used paint sand mill includes a grinding cylinder with a feed inlet and a discharge outlet, a cooling jacket is provided outside the grinding cylinder, and a water inlet and a water outlet are provided on the cooling jacket. The body is provided with grinding beads, a rotating shaft, and a screen. One end of the rotating shaft passes through the grinding cylinder and is connected to the motor through a mechanical transmission mechanism. Several grinding discs are welded on the rotating shaft located in the grinding cylinder. When working, the paint is input into the grinding cylinder from the feed port, and the motor drives th...

Problems solved by technology

[0003] When the above-mentioned paint sanding machine is in use, the temperature is cooled by water cooling. Since the drive of the water cooling system operates independently, the inflow and outflow of water flow is carried out at a constant speed. When the water flow speed is controlled too high, although it can achieve better cooling effect, but it will cause a great waste of water resources, and the water heat absorption efficiency is not high; when the speed of the controlled water flow is too small, the cooling effect on the cylinder is not good, and it is difficult to achieve the purpose of cooling; at the same time, due to the sand mill During the stacking process, the material storage device is prone to compaction, which is not conducive to the discharge and transportation of paint. In addition, in the process of discharging materials from the storage device, it is often necessary to rely on external forces for suction. To complete the unloading, it not only needs to consume additional power, but also cannot achieve a good conveying effect for the paint inside the storage device
