Description

Technical Field

[0001] This utility model relates to the field of fire-retardant coating processing technology, specifically a fire-retardant coating preparation and mixing device with automatic proportioning function. Background Technology

[0002] Fire-retardant coatings, as an important fire protection material, are widely used in construction, petroleum, chemical, and power industries. They slow down the combustion rate of the substrate by forming a fire-resistant protective layer, thus buying valuable time for personnel evacuation and firefighting rescue. The performance of fire-retardant coatings depends not only on their formulation composition but also on the accuracy of raw material proportioning and the uniformity of mixing during the preparation process. Currently, the preparation of fire-retardant coatings mostly uses traditional mixing equipment, and the raw material proportioning mainly relies on manual operation, i.e., manually weighing each component raw material and then adding it to the mixing equipment for stirring. To improve the processing efficiency of fire-retardant coatings, some new types of mixing equipment have emerged on the market.

[0003] For example, utility model patent CN217568363U discloses a fire-retardant coating preparation device for cabinet processing. The device features a sealing cover on top of a mixing tank, a stirring motor on the cover, a stirring rod below the cover, a scraping mechanism inside the mixing tank, a discharging mechanism below the tank, a support plate above the tank, symmetrically arranged material buckets above the support plate, a metering valve below the material buckets, and a flexible hose connecting the support plate to the bottom of the sealing cover. The support plate is symmetrically connected to the sealing cover via telescopic rods. This fire-retardant coating preparation device, through the metering valve and material buckets, enables simultaneous automatic metering and dispensing of multiple raw materials, avoiding the need for pre-mixing in traditional methods and significantly saving time in paint mixing. Simultaneously, the scraping mechanism inside the mixing tank automatically cleans the inner walls without manual opening, providing convenience and preventing workers from inhaling harmful gases emitted by the paint, thus ensuring employee health.

[0004] The fire-retardant coating preparation device provided by the aforementioned patent has the advantages of improving preparation efficiency and automatically cleaning the inner wall of the mixing tank. The device controls the amount of material through a metering valve and uses gravity to allow the material to enter the mixing tank. However, this design has a drawback—if the raw material becomes blocked in the pipeline, it cannot enter the mixing tank smoothly by gravity alone, thus affecting the processing flow of the fire-retardant coating.
