Description

Technical Field

[0001] The utility model relates to the technical field of fire retardant coating spraying equipment, in particular to a non-expansion type gypsum-based steel structure fire retardant coating spraying device. Background Art

[0002] As the main form of modern architecture, steel structure has the advantages of light weight, high strength, good seismic performance, etc. However, the disadvantage of poor fire resistance of steel structure buildings is also very obvious. Because steel is a good conductor of heat, it will lose its bearing capacity at a temperature of 450-650℃ and undergo a large deformation, causing steel columns and beams to bend and even collapse. Therefore, in order to improve the fire resistance of steel structures, a fire retardant coating is usually sprayed on the surface of steel structures. The main types of fire retardant coatings are expansion type and non-expansion type. Non-expansion fire retardant coatings are mixed with suitable inorganic binders, inorganic lightweight insulating aggregates, flame retardants, additives and reinforcing materials. At present, gypsum is generally used as an inorganic binder to make non-expansion gypsum-based steel structure fire retardant coatings.

[0003] In the conventional fire retardant coating spraying construction process, the main materials used are fire retardant coating powder and water. The construction process is: first, the fire retardant coating is prepared, that is, the fire retardant coating powder and water are mixed and stirred into slurry through a mixer, and then sprayed, that is, the prepared slurry is poured into the sprayer hopper and the slurry is sprayed on the surface of the steel structure by the sprayer. Since this construction process uses two separate equipment for stirring and spraying, there are problems such as low construction efficiency and serious environmental pollution in the workplace.

[0004] At the same time, when non-expanding gypsum-based steel structure fire retardant coating is sprayed onto the surface of the steel structure, in order to make the coating quickly solidify and cure, a quick-setting agent needs to be added to the coating, but traditional sprayers do not have a device for effectively adding quick-setting agents.

[0005] Therefore, it is particularly important to improve the existing spraying device and design a new non-expanding gypsum-based steel structure fire retardant coating spraying device to solve the above-mentioned technical defects and improve the practicability of the overall spraying device.

[0006] The purpose of the utility model is to provide a non-expanding gypsum-based steel structure fire retardant coating spraying device, which adopts an integrated design of coating preparation and spraying, and also designs an accelerator mixing device.

The outlet of the delivery pump is connected with a coating spray pipe;

[0009] The hydraulic lifting and stirring assembly is used for stirring the coating inside the main material barrel.

The drive motor is fixedly connected to one end of the connecting frame away from the main material barrel. The rotating rod is rotatably connected to one end of the connecting frame close to the main material barrel. The transmission belt is located inside the connecting frame.
