Specific Embodiments
[0013] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.
[0014] Embodiment
[0015] As Figure 1 and Figure 2 shown, the rotatable solution flushing device provided in this embodiment includes a fuel tank 1 and an oil receiving tank 2. Uniformly distributed universal wheels with a self-locking mechanism are installed at the bottom edge of the fuel tank 1. A drain pipe is connected to one side of the fuel tank 1; the oil receiving tank 2 is located above the fuel tank 1, and a pipeline 3 connecting the oil receiving tank 2 and the fuel tank 1 is installed between the bottom of the oil receiving tank 2 and the top of the fuel tank 1;
[0016] Bearing support seats 7 and support plates are respectively installed on the opposite side edges of the oil receiving tank 2. A rotating platform 4 is provided above the oil receiving tank 2. In this embodiment, the rotating platform 4 is located directly above the oil receiving tank 2. Fixed seats 5 with an L-shaped cross-section are fixedly connected to the middle parts of the opposite sides of the rotating platform 4. One of the fixed seats 5 corresponds to the bearing support seat 7, and a rotating shaft 6 is connected between this fixed seat 5 and the bearing support seat 7. One end of the rotating shaft 6 is fixedly connected to the fixed seat 5, and the other end is rotatably matched with the bearing support seat 7. A rotating main shaft 8 coaxial with the rotating shaft 6 is fixedly connected to the other fixed seat 5. The rotating main shaft 8 passes through the support plate, and a bearing cooperating with the rotating main shaft 8 is installed on the support plate. The rotating platform 4 is made of a perforated plate, and two clamping seats 12 are fixedly installed on the surface and bottom of the rotating platform 4 respectively. In this embodiment, two clamping seats 12 are a group and are installed on a connecting plate. The connecting plate is also made of a perforated plate. Through the connecting plate, the quick installation and disassembly between the clamping seat 12 and the rotating platform 4 can be realized. Similarly, for different products, different clamping seats 12 can be fixed on the connecting plate and then quickly fixedly installed with the rotating platform 4. The clamping seat 12 is used to horizontally fix the product to be cleaned. For the four clamping seats 12, four corresponding cleaning liquid pipes 13 are provided. The cleaning liquid pipes 13 can be made of flexible hoses to reduce the load on the rotating platform 4. In this embodiment, the cleaning liquid pipes 13 are made of flexible hoses and there are four, which are respectively located at the top and bottom of both sides of the rotating platform 4. The cleaning liquid pipes 13 are clamped and fixed by hose clamps fixed at the top and bottom of both sides of the rotating platform 4. One end of the cleaning liquid pipe 13 is fixedly connected and communicated with the outer wall of the rotating main shaft 8 near the support plate. The ends of the four cleaning liquid pipes 13 are evenly distributed in a cross shape on the rotating main shaft 8. A quick connector is installed at the other end of the cleaning liquid pipe 13. When the product to be cleaned is fixed on the clamping seat 12, the quick connector is connected to the oil inlet connector of the product to be cleaned through a hose. By opening the oil outlet connector of the product, the flip flushing can be realized; Since a sealing cover body is covered above the oil receiving tank 2, the solution flipped and spilled from the oil outlet connector 20 of the product will finally fall into the oil receiving tank 2 and finally flow into the fuel tank 1;
[0017] The interior of the rotating main shaft 8 is hollow, and the end connected to the fixed seat 5 is closed, while the other end is open. A rotary joint 9 is connected to the open end of the rotating main shaft 8. One end of the rotary joint 9 is a fixed end, and the other end is a rotating end. This component is an existing mature product. In this embodiment, the rotary joint 9 used is the DN91-60 model produced by Zaozhuang Shenglong Metal Products Company. The fixed end of the rotary joint 9 is fixedly connected to the liquid inlet pipe 10, and the rotating end of the rotary joint 9 is fixedly connected to the open end of the rotating main shaft 8. A support platform 15 fixed to the frame is provided below the rotating main shaft 8. Several main shaft support seats 14 are evenly installed on the support platform 15 corresponding to the rotary joint 9 and the rotating main shaft 8. A rotating gear 11 is fixedly sleeved on the rotating main shaft 8. A driven gear is meshed with the rotating gear 11, and a driving gear 17 is also meshed with the driven gear. The driving gear 17 is fixedly connected to the driving shaft of the servo motor 16. By the forward and reverse rotation of the servo motor 16, the rotating main shaft 8 is driven to rotate forward or reverse. Due to the use of the rotary joint 9, the liquid inlet pipe 10 will not rotate, thus realizing stable liquid supply. The rotation of the rotating main shaft 8 drives the rotating platform 4 to rotate. At the same time, the liquid inlet pipe 10 supplies liquid, which is transported through the rotating main shaft 8 to the cleaning liquid pipe 13. The cleaning liquid pipe 13 rotates with the rotating platform 4 and flushes the cleaning medium into the product to be cleaned through the hose. After the cleaning medium flushes inside the product, it leaks out from the oil outlet joint of the product, and finally flows to the fuel tank 1 for recycling through the oil receiving tank 2.
[0018] The above description is only the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification and replacement based on the technical solution and inventive concept provided by the present invention should be covered within the protection scope of the present invention.
