Description

Technical Field

[0001] The utility model relates to the technical field of spray coating material screening, in particular to a raw material screening device for producing fire-resistant anti-slag spray coating material. Background Art

[0002] Paint is applied to the surface of the object to be protected or decorated, and can form a continuous film that is firmly attached to the coated object. It is usually a viscous liquid based on resin, oil, or emulsion, with or without pigments, fillers, and corresponding additives, prepared with organic solvents or water. Any paint that uses water as a solvent or dispersion medium can be called water-based paint. In the production process of water-based paint, in order to ensure the quality of the paint, the raw materials need to be screened in advance, so a raw material screening device is required.

[0003] After massive searches, it was found that the prior art, such as the publication number CN216728150U, is a raw material screening device for water-based paint production, including a device shell, a receiving hopper, a vibration motor, a feed hopper and a screening drawer, the feed hopper is fixed at the top of the device shell, the receiving hopper is arranged at the bottom of the device shell, a discharge port is arranged on the outer wall of the device shell at the position of the receiving hopper, the screening drawer is arranged inside the device shell above the receiving hopper, a drawer opening is arranged on the outer wall of the device shell at the position of the screening drawer, and leakage holes at equal intervals are arranged on the bottom of the screening drawer, and support seats are fixed on both inner walls of the device shell below the screening drawer, the vibration motor is installed inside the support seat, and the output end of the vibration motor extends to the top of the support seat and is fixed with a push plate. The utility model can not only effectively prevent the leakage hole from being blocked by the raw material, making the feeding of the raw material smoother and realizing the intermittent feeding function, but also prevent the dust from being blown out during the feeding. Although this method can play a good screening role for the raw materials, in actual operation, the coating dropped after screening is easy to contact with the vibration motor. Once the raw material enters the inside of the vibration motor, it is easy to affect the normal operation of the vibration motor and reduce its service life.
