Description

Technical Field

[0001] The utility model relates to the technical field of casting surface cleaning, in particular to an automatic cleaning device for castings after demoulding. Background Art

[0002] In the casting manufacturing process, a large amount of sand and impurities often remain on the surface of large castings after demoulding, which not only affects the appearance quality of the castings, but also affects their subsequent performance. After demoulding, effective cleaning of large castings is a crucial link. The traditional method is to use a spray gun to clean them manually, which is inefficient and the cleaning effect is difficult to guarantee.

[0003] The prior art also provides some automated cleaning equipment, which flushes the castings by setting spray guns or nozzles in multiple directions to minimize surface residues. The cleaning efficiency is much higher than manual cleaning. However, due to the complex structure of the castings, the setting of the spray guns or nozzles is difficult to fully meet the flushing requirements. After the automated flushing is completed, it is often necessary to manually use a spray gun to flush specific locations again. When dealing with castings of different structures, the spray guns or nozzles need to be readjusted, affecting production efficiency.

[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0025] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "front", "back", "horizontal", "vertical", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention. They cannot indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0026] See also Figures 1 to 4 , the first embodiment of the utility model provides an automatic cleaning device for a casting 4 after demoulding, comprising: a traveling crane 1, a cleaning tank 2 and a water pump;

[0027] The crane 1 is a double-track crane 1, which is erected above the water tank, and lifts the casting 4 from the position after demoulding, moves it and places it into the cleaning tank 2;

[0028] An ultrasonic cleaning area is provided in the cleaning tank 2 to perform ultrasonic cleaning on the passing casting 4 to remove sand and impurities on the surface;

[0029] The ultrasonic cleaning area is set in the middle left area of ​​the entire cleaning tank 2. In the ultrasonic cleaning area, ultrasonic transducers are evenly distributed on both side walls and the bottom. The ultrasonic transducers on the same side wall or bottom are grouped together and controlled independently. One or more groups of ultrasonic transducers can be turned on according to the specific structure of the casting 4 to achieve the corresponding cleaning requirements.

[0030] The output end of the water pump is connected to the right end of the water tank, and the input end is connected to the left end of the water tank. By pumping the cleaning liquid 21, the liquid in the tank flows from right to left, and the flow rate is controlled at 1-1.2 m / s. The sand and impurities separated from the casting 4 will flow away with the liquid;

[0031] A filter structure 3 is also provided in the cleaning tank 2, located at the left end of the cleaning tank 2, to filter out washed sand and impurities.

[0032] Specifically, the double-track vehicle 1 includes two pairs of hooks, which hook the four directions of the casting 4 to keep it balanced during lifting. The casting 4 can be lifted by replacing the hooks with different shapes and structures, and the vertical and horizontal directions of the casting 4 can also be adjusted to adapt to the lifting.

[0033] Specifically, a pair of guide bars are provided in the cleaning tank 2, and corresponding guide grooves 31 are provided on both sides of the filter structure 3. The filter structure 3 is placed along the direction of the guide bars to stabilize it in the cleaning tank and block sand and impurities.

[0034] The filter structure 3 is L-shaped, like a dustpan. When the device is working, sand and impurities will accumulate in the filter structure 3. When the filter structure 3 is pulled upward, the blocked sand and impurities can be taken out together, so the filter structure 3 can be replaced online to make the device work normally.

[0035] Specifically, the filter structure 3 adopts a polypropylene filter, which has the advantages of being light and easy to process. In this embodiment, the casting 4 is a ship's electric propulsion shell casting 4, and the cleaning liquid 21 is tap water without strong acid and strong alkali components. The use of a polypropylene filter is more economical.

[0036] A filter is also provided at the input end of the water pump to filter out the small amount of sand and impurities remaining in the cleaning liquid to avoid clogging.

[0037] In order to better control the energy consumption of the device, a pair of sensing devices are also set on the cleaning tank:

[0038] A pair of sensing devices are located before and after the ultrasonic cleaning area. When the casting 4 enters the ultrasonic cleaning area, the corresponding ultrasonic transducer group is activated, and when the casting 4 leaves the ultrasonic cleaning area, it is turned off.

[0039] The beneficial effects of the automatic cleaning device after demoulding of a casting in the utility model are:

[0040] 1. Use a crane to hoist the castings, and use the dual effects of ultrasound and water flow in the cleaning tank to clean large castings. The high degree of automation effectively improves the cleaning efficiency and cleaning effect. Usually, the cleaning time of a single casting is within ten minutes;

[0041] 2. It can be applied to all kinds of large castings, has high adaptability to casting structures, is easy to operate and has high production efficiency;

[0042] 3. A removable filter structure is set up to clean the sand and impurities in the tank in time to ensure the normal operation of the device.

[0043] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
