Abstract
Description
Technical Field
[0001] This utility model belongs to the field of metal cleaning technology, and specifically relates to a metal casting cleaning device. Background Technology
[0002] Metal casting is a common industrial production process, involving pouring molten metal into prefabricated molds to form parts of the desired shape. Metal castings offer advantages such as low manufacturing cost, complex shapes, and wide applications, finding widespread use in machinery, automotive, military, and aerospace industries. Cleaning metal castings removes surface contaminants such as oxide layers, rust, grease, lubricants, foundry sand residue, welding marks, spatter, and old coatings or paints. These contaminants affect the appearance quality of the metal castings and hinder further processing. Common cleaning methods include water rinsing, mechanical cleaning, and ultrasonic cleaning. Ultrasonic cleaning typically uses high-frequency vibrations generated by an ultrasonic transducer to create cavitation in the cleaning medium, thus removing dirt from the casting surface. However, for stubborn oil stains, grease, or large pieces of dirt, ultrasonic cleaning alone may not be sufficient. If the metal castings are pre-treated before ultrasonic cleaning, each casting needs to be removed individually, which is time-consuming and labor-intensive.
[0003] In summary, existing technologies suffer from the problem that metal castings need to be removed one by one for subsequent cleaning after pretreatment, which is time-consuming and labor-intensive. Utility Model Content

[0025] The following is in conjunction with the appendix Figure 1-6 This utility model will be described in further detail below.
[0026] Example 1, refer to Figure 1-6 In this embodiment, to solve the problem of time-consuming and labor-intensive subsequent cleaning of metal castings after pretreatment, this utility model discloses a metal casting cleaning device, including a water storage tank 4, a pretreatment tank 3, and an ultrasonic cleaning tank 2. The three tanks are distributed from left to right on the workbench 9. The water storage tank 4 is connected to the top and side of the pretreatment tank 3 and the ultrasonic cleaning tank 2 through a first inlet pipe 5 and a second inlet pipe 7, respectively. A first pump body 6 and a second pump body 8 are provided on the first inlet pipe 5 and the second inlet pipe 7 to facilitate the subsequent injection of water into the pretreatment tank 3 and the ultrasonic cleaning tank 2. The pretreatment tank 3 and the first inlet pipe 5 are connected through a feeding box 30, which can hold cleaning liquids such as detergent. When water passes through the feeding box 30, it will carry the cleaning liquid inside into the pretreatment tank 32 for subsequent pretreatment operations. Below the handle 31 is a sealing cover, which is adapted to the feeding box 30 for subsequent addition of cleaning liquids such as detergent. The pretreatment tank 3 contains, from top to bottom, a pretreatment tank 32, a sealing layer 28, and a residue collection box 29. The cross-sectional areas of the sealing layer 28 and the residue collection box 29 are both larger than the bottom area of the pretreatment tank 32, and the height of the residue collection box 29 is greater than the height of the pretreatment tank 32. When the sealing layer 28 is removed, the wastewater inside the pretreatment tank 32 will fall into the residue collection box 29. The sealing layer 28 is provided with a rubber layer to prevent water penetration and ensure the sealing of the pretreatment tank 32.
[0027] A gantry frame 1 is installed at the rear of the workbench 9. An air pump 11 is installed above the gantry frame 1. The air pump 11 is connected to a push rod 13 via a telescopic rod 12. The push rod 13 is connected to a push plate 16 below. The width of the push plate 16 is the same as the width of the pretreatment tank 32. Driven by the air pump 11, it can move left and right. The push plate 16 is a telescopic structure, which is fixed by bolts. There are two positioning holes on the top of the push plate 16. The length of the push plate 16 is controlled by the position of the bolts. The maximum length of the push plate 16 is the length from the gantry frame 1 to the bottom of the sealing layer 28. A sealing door 21 is installed on the side of the pretreatment tank 32 near the ultrasonic cleaning box 2. The bottom of the sealing door 21 extends to the bottom of the sealing layer 28. The top is connected to a rotating shaft 17 via a connecting plate 18. The sealing door 21 is adapted to the through hole on the side of the pretreatment tank 32. The inside of the sealing door 21 is a rubber block 22, which plays a sealing role and is connected to the sealing layer. The 28-phase fitting ensures that the pretreatment tank 32 will not leak. The pretreatment tank 32 has a groove on the top side near the ultrasonic cleaning box 2, with a fixed shaft 23 on the groove. The rotating shaft 17 is sleeved on the fixed shaft 23. The connecting plate 18 fits into the groove. Fixed blocks 25 are welded to the top of both ends of the fixed shaft 23. The rotating rod 26 is set on the fixed blocks 25 and fixed by the sealing block 24 to prevent it from falling off and ensure the stability of the rotating rod 26. The rotating rod 26 is connected to a high-strength spring and a fixed hook 27. The fixed hook 27 is connected to the fixed half-ring 19 on the side of the sealing door 21. Through the fixed distance of the rotating rod 26, when the fixed hook 27 and the fixed half-ring 19 match, the rotating rod 26 will be subjected to a compressive force at an inclined angle, thus preventing further rotation and achieving a fixing effect. A handle 20 is provided below the fixed half-ring 19 for easy manual closing and opening of the sealing door 21. Alternatively, a hydraulic pump or a second air pump can be connected to the push rod 13 via a telescopic plate and the push plate 16 to further save manpower.
[0028] The height of the ultrasonic cleaning box 2 is the same as that of the residue collection box 29, and one side of the ultrasonic cleaning box 2 is connected to the pretreatment box 3. Both the residue collection box 29 and the sealing layer 28 are provided with annular columns to facilitate the removal of the residue collection box 29 and the sealing layer 28. The top of the residue collection box 29 is fixed with the filter plate 34 by the positioning plate 33. When the metal casting falls onto the filter plate 34, the push plate 16 is opened to the maximum position, the sealing door 21 is opened, and the metal casting is pushed into the ultrasonic cleaning box 2 by the movement of the push plate 16. Ultrasonic transmitters 38 are provided on both sides of the bottom of the ultrasonic cleaning box 2. The cleaning tank 39 and the ultrasonic cleaning box shell 35 are filled by the buffer block 37 or only the bottom is provided with the buffer block. The top of the cleaning tank 39 is connected to the ultrasonic cleaning box shell 35 by the inclined plate. The bottom of the ultrasonic cleaning tank 2 is provided with a drain outlet, which is sealed by a water-blocking block 36. The pretreatment tank 32 and the cleaning tank 39 are respectively provided with a first viewing window 14 and a second viewing window 15 on their front and side sides for observing the water level inside.
[0029] Specific implementation principle: When using this utility model, firstly, place the metal casting to be cleaned inside the pretreatment tank 32. Determine the cleaning solution based on the surface dirt condition. After opening handle 31 and pouring the cleaning solution into the loading tank 30, close the sealing cover and start the first pump body 6. Water in the water storage tank 4 will carry the cleaning solution into the pretreatment tank 32 through the first liquid inlet pipe 5. When the water submerges the metal casting, turn off the first pump body 6. After standing for a fixed time, remove the sealing layer 28, and the metal casting will fall onto the filter plate 34. By adjusting the position of the bolt holes, place the push plate 16 inside the pretreatment tank 32. The leftmost part contacts the filter plate 34. Pull the handle 20 to rotate the rotating rod 26 and connect it to the fixed half ring 19, fixing the sealing door 21. Start the air pump 11, and the push plate 16 drives the metal casting to move. The metal casting moves into the cleaning tank 39. Start the second pump body 8 and inject water through the second liquid inlet pipe 7. Observe the water injection through the second viewing window 15 to see if the second pump body 8 is closed. Then start the ultrasonic transmitter 38 for further cleaning. The whole process does not require removing the metal casting one by one and can be done in batches. The pre-treated metal casting is ultrasonically cleaned, which ensures the quality of cleaning.
[0030] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
