[0040] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic structural diagram of a first embodiment of a device for treating the surface of a steel casting provided by the present invention; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 A schematic diagram of the three-dimensional structure of the entire internal structure of the device shown; Figure 4 for Figure 1 A schematic diagram of the overall external three-dimensional structure of the device shown; Figure 5 for Figure 1 The isometric structural diagram of the whole device is shown. A surface anti-corrosion treatment device for a steel casting comprises:

[0041] A sandblasting machine body 1, wherein a mounting assembly 2 is arranged inside the sandblasting machine body 1;

[0042] A fixing device 4, the fixing device 4 is arranged above the mounting assembly 2, the fixing device 4 comprises a double-headed hydraulic telescopic rod 41, both ends of the double-headed hydraulic telescopic rod 41 are connected to a connecting frame 42, and opposite sides of the two connecting frames 42 are connected to a fixing block 43;

[0043] The spray head 6 is installed on the top of the inner wall of the spray machine body 1.

[0044] The mounting assembly 2 includes a mounting base 21 , and fixing rods 22 are symmetrically connected to two sides of the surface of the mounting base 21 .

[0045] The mounting base 21 is connected to the center position of the bottom of the inner wall of the sandblasting machine body 1. The use of the double-headed hydraulic telescopic rod 41 can drive the two fixing blocks 43 to move through the two connecting frames 42 to fix the cast steel part. The use of multiple through holes 5 can transport the liquid generated by the spraying of the spray head 6 to the inside of the collection box 8 for collection.

[0046] A mounting plate 23 is connected between the two fixing rods 22 .

[0047] A fixing ring 44 is connected to the center of the surface of the double-headed hydraulic telescopic rod 41 , and the fixing ring 44 is connected to the center of the bottom of the mounting plate 23 .

[0048] A plurality of through holes 5 are formed at the bottom of the inner wall of the sandblasting machine body 1 , and a baffle 9 is connected to the bottom of the inner wall of the sandblasting machine body 1 and located on a side opposite to the mounting seat 21 .

[0049] A mounting seat 7 is connected to the bottom of the sandblasting machine body 1 , a collecting box 8 is arranged inside the mounting seat 7 , and a movable door 10 is arranged on the back of the sandblasting machine body 1 .

[0050] The composition of the sandblasting machine body 1:

[0051] Structural system:

[0052] Body: It is the outer shell and supporting structure of the equipment, which protects the internal components and provides an installation basis. It is usually made of corrosion-resistant materials such as fiberglass and stainless steel to prevent the equipment from being corroded by water and abrasives.

[0053] Sandblasting cabin: It is a space where sandblasting operations are carried out. The workpiece is sprayed with a mixed flow of abrasive and water in the sandblasting cabin. Protective devices, such as wear-resistant rubber plates, are usually installed in the sandblasting cabin to protect the inner wall of the sandblasting cabin from wear by abrasives.

[0054] Medium power system:

[0055] Sand pump: As a power device for supplying grinding fluid (a mixture of abrasive and water), it delivers the evenly stirred grinding fluid to the spray gun. The performance of the sand pump directly affects the supply stability and injection pressure of the grinding fluid.

[0056] Compressed air system: Provides compressed air as a power source. The compressed air is transported to the spray gun through a pipeline to provide acceleration power for the spraying of the grinding fluid. The compressed air system usually includes air compressors, air tanks, filters, pressure reducing valves and other components to ensure that the compressed air provided is dry, clean and has stable pressure.

[0057] Pipeline system: pipes and valves connecting various components, including grinding fluid delivery pipes, compressed air pipes, water inlet pipes, and drainage pipes. The design and installation of the pipeline system must ensure the smooth flow of grinding fluid and compressed air, and facilitate maintenance and replacement.

[0058] Control system: used to control the operation of the equipment, including the adjustment and setting of parameters such as sandblasting pressure, sandblasting time, and abrasive fluid flow. The control system can adopt electrical control, pneumatic control or PLC control to meet different operating requirements.

[0059] Assistance Systems:

[0060] Abrasive storage tank: used to store abrasive, usually connected to a sand pump to transport abrasive to the sandblasting gun.

[0061] Water filtration system: Filter the water to remove impurities and pollutants in the water to ensure the quality of the grinding fluid and the sandblasting effect.

[0062] Lighting system: Provides lighting inside the sandblasting cabin to facilitate operators to observe the sandblasting operation.

[0063] The working principle of the wet sandblasting machine is: the sand pump delivers the evenly stirred abrasive liquid (a mixture of abrasive and water) to the spray gun. Under the acceleration of compressed air, the abrasive liquid is ejected at high speed through the nozzle to form an abrasive water mixed jet, which is sprayed onto the surface of the workpiece to be processed. The addition of water can reduce the wear and heat generation of sand particles and reduce damage to the surface of the workpiece. At the same time, the impact force of water can wash away dirt and impurities from the surface of the workpiece to achieve the purpose of cleaning, removing oxide scale, and increasing surface roughness. After the abrasive liquid is sprayed onto the surface of the workpiece, it will rebound back into the sandblasting cabin, be filtered and recycled through the recovery device, so as to save abrasive and water resources.

[0064] A method for treating the surface of a steel casting with an anti-corrosion device, which requires the use of the steel casting surface anti-corrosion device, comprises the following steps:

[0065] S1. When the steel casting is subjected to water washing and spraying operation, the movable door 10 on the back of the sandblasting machine body 1 is first opened. After the movable door 10 is opened, the steel casting is placed at the center of the surface of the mounting plate 23;

[0066] S2. After placing the steel casting, start the double-headed hydraulic telescopic rod 41 to drive the two connecting frames 42 to move toward the middle. When the two connecting frames 42 move to one side of the steel casting, they drive the fixing block 43 to move. When the two fixing blocks 43 are in contact with and fixed to the steel casting, take out the spray head 6 inside the sandblasting machine body 1 to perform anti-corrosion treatment on the steel casting.

[0067] The working principle of the surface anti-corrosion treatment device for steel castings provided by the present invention is as follows:

[0068] When using, when water washing and spraying operation is performed on the steel casting, the movable door 10 on the back of the sandblasting machine body 1 is first opened. After the movable door 10 is opened, the steel casting is placed at the center position of the surface of the mounting plate 23.

[0069] After the steel casting is placed, the double-headed hydraulic telescopic rod 41 is started to drive the two connecting frames 42 to move toward the middle. When the two connecting frames 42 move to one side of the steel casting, they drive the fixing block 43 to move. When the two fixing blocks 43 are in contact and fixed with the steel casting, the spray head 6 inside the sandblasting machine body 1 is taken out to perform anti-corrosion treatment on the steel casting.

[0076] The disassembly sleeve 111 is connected to the top end of the fixing rod 22 , and the disassembly sleeve 111 and the disassembly block 112 are connected by plugging and unplugging.

[0077] The working principle of the surface anti-corrosion treatment device for steel castings provided by the present invention is as follows:
