Description

Technical Field

[0001] The utility model belongs to the technical field of fire retardant coatings, and particularly relates to a spraying device for fire retardant coatings. Background Art

[0002] Most of the current buildings are built with steel structures. In order to improve the fire resistance of buildings, it is necessary to spray fireproof materials on the surface of steel structures. The so-called fireproof coating is to brush the coating on the surface of those flammable materials to improve the fire resistance of the materials, slow down the spread of flames, or prevent combustion within a certain period of time. This type of coating is called fireproof coating, or flame retardant coating. Fireproof coating is a special coating used on the surface of combustible substrates to reduce the flammability of the surface of the coated material, block the rapid spread of fire, and improve the fire resistance limit of the coated material. It is applied to the surface of combustible substrates to change the combustion characteristics of the material surface and block the rapid spread of fire; or applied to building components to improve the fire resistance limit of the components. In actual operation, operators need to spray steel structures at least 2 or 3 times, and in order to improve the fire protection efficiency, the concentration of the paint for the second or third spraying should be higher. However, most of the spraying equipment on the market can only be filled with paint of the same concentration, which affects the spraying efficiency. In addition, the nozzle structure of the spraying equipment is single in shape, resulting in a small spraying range and low spraying efficiency, which objectively increases the workload of operators.

[0003] In response to the above problems, the Chinese utility model patent with application number 202020295696.6 discloses a steel structure fire retardant coating spraying equipment, including a shell, a first coating tank is installed in the shell, a second coating tank is installed on the right side of the first coating tank, a coating intermediate tank is installed below the first coating tank and the second coating tank, the first coating tank is connected to the coating intermediate tank through a first discharge valve, the second coating tank is connected to the coating intermediate tank through a second discharge valve, a delivery pipe is connected to the bottom of the right side of the coating intermediate tank, a delivery pump is installed on the delivery pipe, one end of the delivery pipe is connected to the coating intermediate tank, and the other end is connected to the nozzle; the nozzle is provided with a large diameter part and a small diameter part, a guide frame is installed on the nozzle, and the shell is placed horizontally on a mobile platform. The equipment can effectively expand the spraying range of the nozzle and improve the spraying efficiency.

[0004] However, the equipment still requires the operator to move the nozzle to spray the fire retardant coating. The spraying effect depends on the operator's construction level, which can easily cause uneven spraying. In addition, the spraying operation construction environment is poor, which can easily affect the health of the construction workers. Therefore, it is necessary to provide a semi-automatic spraying equipment to ensure the fire retardant coating spraying effect and reduce the work intensity of the construction workers.
