Description

Technical Field

[0001] The utility model relates to the technical field of coating production equipment, in particular to a mixing device for processing fire-retardant coatings. Background Art

[0002] In the prior art, steel structure is a structure composed of steel materials and is one of the main types of building structures. After production and assembly, each assembly part of the steel structure will be sprayed with various coatings. The so-called coating 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 made of resin, oil or emulsion, with or without pigments, fillers, and corresponding additives, and prepared with organic solvents or water. Fire retardant coating improves the fire resistance of the structure.

[0003] After searching, the Chinese patent application number 202021911861.2 discloses a mixing device for the production and processing of fire retardant coatings, including a hydraulic column, a top box arranged above the hydraulic column, a driving gear arranged inside the top box and located on one side of the top box, a driven gear arranged on the other side of the top box and maintained a transmission connection with the driving gear, a drive motor maintained a transmission connection with the driving gear and fixedly arranged under the top box, a stirring shaft coaxially connected to the driven gear, a stirring blade arranged on the stirring shaft, a paint bucket used in conjunction with the stirring blade and located directly below the stirring shaft and the stirring blade for holding the paint, and a clamping assembly used in conjunction with the paint bucket and used to fix the paint bucket; two lugs are arranged on the outside of the paint bucket, and a roller is arranged at the bottom of the paint bucket.

[0004] The above patent has the following shortcomings: the device is provided with a hydraulic column to ensure that the stirring blades can move up and down while the paint is rotating during the stirring process, fully ensuring that the paint can be stirred evenly; however, in actual use, the purpose of controlling the reciprocating lifting and lowering of the stirring blades is achieved by controlling the repeated extension and retraction of the hydraulic column. Although its overall structure is relatively simple, the hydraulic column needs to lift too many structures, and it is relatively unsafe during use, which is not conducive to the long-term use of the overall device.
