[0023] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a single-unit device for cleaning the inner cavity of castings.

[0024] like Figures 1-5 As shown, this utility model includes: a workbench 0, a part of the equipment placed below the workbench 0, and a fixture 9 placed on the workbench 0; wherein,

[0025] The workbench frame is divided into several layers: (in this embodiment, there are two layers: upper and lower); it is composed of a vertical rectangular workbench placed below and a conical platform placed above; (in this embodiment, the vertical rectangular workbench is a vertical rectangular frame composed of four steel, stainless steel, and iron plates, and its four sides are inlaid with vertical cabinets composed of steel, stainless steel, and iron plates; the conical platform is a frustum-shaped frame with a wider bottom and a narrower top composed of four steel, stainless steel, and iron plates, and its four sides are inlaid with frustum-shaped cabinets composed of steel, stainless steel, and iron plates; and its four wider bottom sides are fastened to the top plate on the vertical rectangular workbench).

[0026] The middle part of the workbench frame 0 is equipped with a double-control start switch 2 and an emergency stop button; the double-control start switch 2 and the emergency stop button are connected to the single-opening safety door 1; (in this embodiment, the connection is made by electrical connection; the opening and closing of the single-opening safety door 1 is controlled by the double-control start switch 2 and the emergency stop button).

[0027] In front of the vertical rectangular workbench below is a double or single safety door 1 (in this embodiment, it is a single safety door 1; inside, from front to back, on the bottom plate of the vertical rectangular workbench, there are air tanks 3, steel shot bins 4, and steel shot screens 5); (in this embodiment, two air tanks 3 are installed at the top and bottom positions of the single safety door 1, and the two air tanks 3 are welded together by two steel plates; on top of the two air tanks 3, there are two steel plates welded together with hollow steel plates perpendicular to and parallel to them).

[0028] Gas tank 3: Provides the gas needed for cleaning operations to nozzle 7;

[0029] The placement of the steel shot hopper 4 and the steel shot screen 5 is as follows: the steel shot hopper 4 and the steel shot screen 5 are placed on a vertical rectangular workbench from bottom to top, and are parallel to the gas tank 3.

[0030] Several diaphragm valves 6 are connected to the bottom of the steel shot bin 4 and the steel shot screen 5 (in this embodiment, there are three diaphragm valves 6, which are respectively connected to three pipes; the nozzles 7 are respectively installed on the three pipes).

[0031] Diaphragm valve 6: Affects the operation of nozzle 7. Nozzle 7 will only work when the diaphragm valve 6 is turned on. The opening and closing of diaphragm valve 6 can also be adjusted depending on the type of casting being cleaned.

[0032] Shot chamber 4: Provides the steel shot needed for cleaning operations by nozzle 7;

[0033] Steel shot screen 5: Used to separate steel shot from sand.

[0034] The dual-control start switch 2 requires the operator to press both hands simultaneously for the equipment to operate normally. Pressing the emergency stop button will stop the equipment from operating, preventing employees from placing their hands in dangerous positions and causing work-related injuries or affecting the operation of the nozzle 7.

[0035] Nozzle 7: Sprays out steel shot to clean the inner cavity of the casting.
