Description

Technical Field

[0001] The utility model relates to the technical field of fire retardant coating production, in particular to a dry mortar mixer for fire retardant coating production. Background Art

[0002] Fire retardant coating is used on the surface of combustible substrates. It can reduce the flammability of the coated material surface, block the rapid spread of fire, and improve the fire resistance of the coated material. It is a special coating that can change the combustion characteristics of the material surface and block the rapid spread of fire. It is often used on building components to improve the fire resistance of the components. In the process of preparing fire retardant coating, the raw materials need to be mixed evenly by a mixer.

[0003] For example, the patent document with the announcement number CN220968936U discloses a premix dry powder mixing equipment for the production of fire retardant coatings. The fire retardant coating dry powder is fully premixed through the cooperation of a frame, a connecting column, a premixing box, a sealing plate, a stirring roller, an adjustment component, a crushing ball, etc., and by opening the air inlet valve, it is convenient to blow air into the premixing box so as to blow out and collect the fire retardant coating adhered to the inner wall of the premixing box, thereby reducing the influence of the fire retardant coating dry powder on the subsequent premixing efficiency.

[0004] However, during use, although the above patent can blow air into the premixing box through the air inlet pipe, so as to facilitate the collection of the adhered paint dry powder through the discharge pipe, the air inlet pipe is not located at the center of the premixing box, and the air inlet pipe can only discharge air downwards and cannot change the air outlet angle. Therefore, the air inlet pipe cannot completely clean the fire retardant paint adhered to the inner wall of the premixing box. Utility Model Content
