Cleaning equipment

Abstract

As shown in the [Reference Diagram Showing the State of Use], the "cleaning device" of the present design is attached to a container, such as a reaction tank, in a state of hanging down from the upper wall to remove objects adhering to at least the inner surface of the upper wall. As shown in the [Reference Diagram Showing the Basic Configuration of the Spray Unit], the "cleaning device" comprises a cleaning device main body, a cleaning liquid supply pipe that supplies cleaning liquid to the pressure chamber of the cleaning device main body (see the [Reference Diagram Showing the Inclined State of the Spray Nozzle]), a diffusion spray unit that diffuses and sprays the cleaning liquid from the pressure chamber, and a linear spray unit that sprays the cleaning liquid from the pressure chamber in a straight line. The cleaning device main body has a diverging portion, a cylindrical portion, and a tapered portion. The diverging portion has eight diffusion spray units spaced at 45-degree intervals. The cylindrical portion also has five linear spray units spaced at 45-degree intervals, and the tapered portion has two linear spray units spaced apart in the direction of the centerline of the cleaning device main body when viewed from the front. As shown in the [Enlarged View of the MN Part], the diffusion spray unit sprays cleaning liquid in a straight line and has a pair of spray holes formed in the cleaning device body so that the sprayed cleaning liquid collides with each other and diffuses. The straight spray unit is a simple through-hole, and users can add additional straight spray units to the factory-manufactured basic cleaning device as needed. For example, as shown in the [Reference Diagram Showing a First Additional Straight Spray Unit], three additional straight spray units can be added. Furthermore, as shown in the [Reference Diagram Showing a Second Additional Straight Spray Unit], four additional straight spray units can be added.
