Description

Technical Field

[0001] This utility model relates to the field of aluminum casting parts processing technology, and more specifically, to an automatic cleaning device for aluminum casting parts. Background Technology

[0002] In modern manufacturing, cast aluminum parts are widely used in the automotive, aerospace, and machinery manufacturing industries due to their lightweight, high strength, and corrosion resistance. However, during the casting process, some impurities remain on the surface of cast aluminum parts, such as dust adhering during demolding or transportation, or impurities adhering from other equipment during demolding. These impurities not only affect the appearance quality of the parts but also reduce their assembly accuracy and performance. Therefore, the cleaning process is an indispensable and crucial step in the production process of cast aluminum parts.

[0003] Currently, the cleaning methods for cast aluminum parts mainly include manual cleaning and mechanical cleaning. Manual cleaning is not only labor-intensive and inefficient, but its effectiveness is also greatly affected by the operator's experience and skill level, making it difficult to guarantee consistent cleaning quality. It also poses problems such as dust pollution and safety hazards. While existing mechanical cleaning equipment, such as drum cleaning machines and shot blasting machines, improves cleaning efficiency to some extent, it still has many shortcomings. For example, these machines have poor adaptability to cast aluminum parts of different shapes and sizes, making it difficult to achieve all-around cleaning; the cleaning process can easily cause surface damage to parts, affecting product qualification rates. Therefore, we propose an automatic cleaning device for cast aluminum parts. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-3This utility model provides a technical solution: an automatic cleaning device for cast aluminum parts, including a cleaning tank 1. The left and right side plates of the cleaning tank 1 are provided with inlet and outlet holes 10. A mesh conveyor belt 11 is installed inside the cleaning tank 1. Both ends of the mesh conveyor belt 11 pass through the two inlet and outlet holes 10 to the outside of the cleaning tank 1. The mesh conveyor belt 11 is driven by a sprocket on an external drive shaft, which is driven by an external motor. The surface of the mesh conveyor belt 11 has a mesh-like structure, allowing it to pass through the inlet and outlet holes 10 and rotate continuously via the sprocket on the external drive shaft. This automatically transports the cast aluminum parts into the cleaning tank 1 for cleaning, replacing manual handling, improving cleaning efficiency, and the mesh-like structure facilitates sewage leakage, which is beneficial for subsequent sewage discharge.

[0030] like Figure 1 and Figure 2 As shown, a rinsing and cleaning assembly 2 is provided on the cleaning tank 1. The rinsing and cleaning assembly 2 includes two symmetrical cylinders 20 fixedly installed on the top surface of the cleaning tank 1 and a delivery pump 24 fixedly installed on the cleaning tank 1. The telescopic shaft ends of the two cylinders 20 extend into the cleaning tank 1 and are detachably installed with anti-splash sleeves 21. An inner arrangement pipe 22 is fixedly installed on the inner wall of the anti-splash sleeve 21. Multiple high-pressure nozzles 23 are fixedly installed on the inner arrangement pipe 22. The delivery pump 24 is connected to the inner arrangement pipe 22 and is used to deliver water to the high-pressure nozzles 23 for rinsing. A suction pipe 241 is fixedly installed at the water inlet end of the delivery pump 24 and a delivery hose 25 is fixedly installed at the water outlet end of the delivery pump 24. The end of the delivery hose 25 is flange-connected to the inner arrangement pipe 22. The cylinder 20 can drive the anti-splash sleeve 21 to rise and fall to accommodate cast aluminum parts of different heights; the delivery pump 24 draws water through the suction pipe 241, delivers the water to the inner arrangement pipe 22 through the delivery hose 25, and then sprays high-pressure water flow from multiple high-pressure nozzles 23 to achieve efficient rinsing and cleaning of impurities on the surface of the cast aluminum parts, thus meeting the cleaning requirements.

[0031] like Figure 1 As shown, a drain pipe 13 is fixedly installed at the bottom of the cleaning tank 1. The drain pipe 13 is used for the discharge of sewage. A drain slope 12 is provided on the bottom wall of the cleaning tank 1. The drain slope 12 is set at a downward angle of 30° to 45° towards the drain pipe 13 to guide the sewage generated during cleaning to the drain pipe 13, so that the sewage can be discharged from the cleaning tank 1 quickly and smoothly, and avoid the sewage from accumulating in the tank and affecting the cleaning effect and normal operation of the equipment.

[0032] like Figure 1As shown, drip collection hoppers 14, which communicate with the interior of the cleaning tank 1, are fixedly installed on the outer walls of both the left and right sides of the cleaning tank 1. The drip collection hoppers 14 are located below the mesh conveyor belt 11. A drip slope 141 is provided on the bottom wall of the drip collection hopper 14. The drip slope 141 is set at a downward angle of 30° to 60° on the side of the drip slope 14 closest to the cleaning tank 1. This allows the water dripping from the upper part of the drip collection hopper 14 to be collected and discharged in a concentrated manner, keeping the surrounding environment of the equipment dry and reducing the safety hazards caused by the slippery ground.

[0033] like Figure 1 and Figure 3 As shown, side baffles 15 are fixedly installed on the outer walls of the left and right sides of the cleaning tank 1. Multiple water curtains 16 are fixedly installed on the side baffles 15. The water curtains 16 are located above the mesh conveyor belt 11. The side baffles 15 and the water curtains 16 work together to form a protective barrier, effectively blocking the water sprayed from the high-pressure nozzles 23 from splashing outwards during the cleaning process, improving the working environment, reducing water waste, and preventing water from splashing onto the operators. In addition, the water curtains 16 are made of flexible material, so that they will not affect the normal conveying of cast aluminum parts on the mesh conveyor belt 11.

[0034] like Figure 2 As shown, steel plates 201 are fixedly installed at the ends of the telescopic shafts of the two cylinders 20. The splash sleeve 21 is detachably installed on the bottom surface of the steel plate 201 by multiple fastening bolts, which facilitates the disassembly and installation of the splash sleeve 21 and makes it convenient to inspect and maintain the internal components such as the inner arrangement pipe 22 and the high-pressure nozzle 23.

[0035] It is worth noting that after the cast aluminum parts are transported to the cleaning area via the mesh conveyor belt 11 for cleaning, the cleaned cast aluminum parts can be further air-dried or oven-dried to avoid residual moisture affecting the performance of the cast aluminum parts.

[0036] Finally, it should be noted that the cylinder 20 and delivery pump 24 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0037] When using the automatic aluminum casting parts cleaning device of this utility model, the aluminum casting parts to be cleaned are first placed at one end of the mesh conveyor belt 11 located outside the cleaning box 1. The sprocket on the external drive shaft drives the mesh conveyor belt 11 to rotate, and the parts are sent into the cleaning box 1 through the inlet and outlet holes 10.

[0038] Based on the height of the cast aluminum parts, the cylinder 20 is activated, and the telescopic shaft of the cylinder 20 drives the steel plate 201 and the splash sleeve 21 to rise and fall to a suitable position. The delivery pump 24 is then activated, and the delivery pump 24 draws water through the suction pipe 241 and delivers it to the inner arrangement pipe 22 through the delivery hose 25. Then, multiple high-pressure nozzles 23 spray high-pressure water jets onto the parts for a comprehensive rinsing and cleaning.

[0039] During the cleaning process, the wastewater generated is guided by the drainage slope 12 and discharged from the cleaning tank 1 through the drainage pipe 13. Water dripping from the mesh conveyor belt 11 is collected by the drip collection bucket 14 below and discharged along the drip slope 141. The side baffles 15 and the water curtain 16 prevent water splashing, ensuring a clean and safe working environment. After cleaning, the mesh conveyor belt 11 sends the parts out of the cleaning tank 1. The cleaned parts can then be air-dried or oven-dried to prevent residual moisture from affecting the performance of the parts.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
