[0052] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a stainless steel casting surface spraying device.

[0053] A stainless steel casting surface spraying device includes a spraying box 1. An electrostatic eliminator 23 is fixedly connected to the spraying box 1 to eliminate static electricity on the stainless steel casting on the support plate 10, reducing dust adhesion to the stainless steel surface. The spraying box 1 is equipped with a heating element 24 for heating the interior of the spraying box 1, thereby accelerating the drying of the casting after spraying. It also includes:

[0054] Reference Figure 1 and Figure 4 In a preferred embodiment, a moving mechanism is disposed on the spraying box 1 to support and drive the stainless steel casting to move; the moving mechanism includes:

[0055] Four sliding keys 7 are provided, and the four sliding keys 7 are disposed on the spray box 1 and are slidably connected to the spray box 1;

[0056] There are four connecting L-plates 8, which are fixedly mounted on the sliding key 7.

[0057] The box cover 9 is fixedly mounted on the connecting L plate 8;

[0058] A support plate 10 is disposed on the box cover 9 and is fixedly connected to the box cover 9.

[0059] During operation, the lid 9 is manually pulled to move it away from the spray box 1. The lid 9 moves the connecting L plate 8 and the support plate 10. The connecting L plate 8 moves the sliding key 7. The connecting L plate 8 provides support for the lid 9. The stainless steel casting is placed in the middle of the support plate 10 and the lid 9 is pushed. The lid 9 moves the stainless steel casting through the support plate 10, so that the stainless steel casting comes into contact with the static eliminator 23. The static eliminator 23 removes the static electricity from the stainless steel casting, and the lid 9 and the spray box 1 form a sealed space.

[0060] Reference Figure 1 and Figure 2In a preferred embodiment, a spraying mechanism is disposed on the spraying box 1 and is used for spraying stainless steel castings; the spraying mechanism includes:

[0061] The material feeding box 11 is fixedly installed on the spraying box 1;

[0062] A feed pump 12 is mounted on the spray box 1 and is fixedly connected to the feed box 11.

[0063] A material extraction pipe 13 is provided on the material supply box 11 and the material supply pump 12. One end of the material extraction pipe 13 is fixedly connected to the material supply box 11, and the other end of the material extraction pipe 13 is fixedly connected to the material supply pump 12.

[0064] The conveying pipe 14 is disposed on the feeding pump 12 and is fixedly connected to the feeding pump 12;

[0065] Reference Figure 2 In a preferred embodiment, a spraying assembly is disposed on the spraying box 1. The spraying assembly includes:

[0066] The flow divider 15 is fixedly installed on the spray box 1 and fixedly connected to the other end of the material conveying pipe 14;

[0067] Multiple diversion valves 16 are provided, and multiple diversion valves 16 are disposed on the diversion plate 15;

[0068] Multiple spray guns 17 are provided and are fixedly mounted on the flow divider plate 15.

[0069] During operation, the feed pump 12 is started. The feed pump 12 draws paint from the feed box 11 through the extraction pipe 13 and delivers it to the diverter plate 15 through the delivery pipe 14. The diverter plate 15 transports the paint to the diverter valve 16. The diverter valve 16 is used to precisely control the working state of the spray gun 17, thereby achieving more efficient and precise spraying operations.

[0070] Reference Figure 3 and Figure 5 In a preferred embodiment, a filter collection mechanism is disposed on the spray box 1 for collecting dust from the stainless steel surface; the filter collection mechanism includes:

[0071] The collection shell 18 is fixedly installed on the spray box 1;

[0072] A collection box 19 is disposed on the spraying box 1 and is fixedly connected to the spraying box 1;

[0073] The filter plate 20 is fixedly mounted on the collection box 19;

[0074] Two third connecting pipes 21 are provided. Two collection boxes 19 are set on the collection box 19 and the gas purification box 3. One end of the third connecting pipe 21 is fixedly connected to the collection box 19, and the other end of the third connecting pipe 21 is fixedly connected to the gas purification box 3.

[0075] There are two fourth connecting pipes 22, which are disposed on the collection shell 18 and the collection box 19. One end of the fourth connecting pipe 22 is fixedly connected to the collection shell 18, and the other end of the fourth connecting pipe 22 is fixedly connected to the collection box 19.

[0076] During operation, the airflow blows the dust on the surface of the stainless steel casting to the collection shell 18. At this time, the air pressure in the collection box 19 is lower than the air pressure in the spray box 1, so the dust is drawn into the collection box 19 through the fourth connecting pipe 22. The dust does not pass through the filter plate 20 and remains in the collection box 19, while the air passes through the filter plate 20 and the third connecting pipe 21 in sequence and enters the gas purification box 3.

[0077] Two vacuum pumps 2 are provided, and the two vacuum pumps 2 are fixedly installed on the spray box 1;

[0078] Two gas purification boxes 3 are provided, and the two gas purification boxes 3 are fixedly installed on the spray box 1;

[0079] The blower housing 4 is fixedly mounted on the spray box 1;

[0080] Two first connecting pipes 5 are provided, and the two first connecting pipes 5 are disposed on the vacuum pump 2 and the blower shell 4. One end of the first connecting pipe 5 is fixedly connected to the vacuum pump 2, and the other end of the first connecting pipe 5 is fixedly connected to the blower shell 4.

[0081] There are two second connecting pipes 6, which are disposed on the vacuum pump 2 and the gas purification box 3. One end of the second connecting pipe 6 is fixedly connected to the vacuum pump 2, and the other end of the second connecting pipe 6 is fixedly connected to the gas purification box 3.

[0082] During operation, vacuum pump 2 is started. Vacuum pump 2 draws air from gas purification box 3 through second connecting pipe 6, causing the air pressure in gas purification box 3 to drop. At this time, the air pressure in gas purification box 3 is less than the air pressure in collection box 19, forming an airflow from collection box 19 to gas purification box 3. This makes the air pressure in collection box 19 less than the air pressure in spray box 1, thereby drawing the waste gas generated in spray box 1 into gas purification box 3 through fourth connecting pipe 22, collection box 19, and third connecting pipe 21. The purified air is then transported back to spray box 1 through second connecting pipe 6, vacuum pump 2, and first connecting pipe 5. The air forms an airflow through first connecting pipe 5, and the airflow blows the dust on the surface of the stainless steel casting to collection shell 18.

[0083] Working principle: By manually pulling the cover 9, the cover 9 moves away from the spray box 1. The cover 9 moves the support plate 10. The stainless steel casting is placed in the middle of the moving plate by the operator. Pushing the cover 9, the cover 9 moves the stainless steel casting through the support plate 10, so that the stainless steel casting comes into contact with the static eliminator 23. The static eliminator 23 removes static electricity from the stainless steel casting until the cover 9 and the spray box 1 form a sealed space. The feed pump 12 is started. The feed pump 12 draws paint from the feed box 11 through the extraction pipe 13 and delivers it to the diversion plate 15 through the delivery pipe 14. The diversion plate 15 transports the paint to the diversion valve 16. The diversion valve 16 is used to precisely control the working state of the spray gun 17 to complete the spraying of the casting. The vacuum pump 2 is started. Air is drawn from the gas purification box 3 through the second connecting pipe 6 and transported to the spray box 1 through the first connecting pipe 5. This creates an airflow that blows the dust on the surface of the casting to the collection shell 18. The vacuum pump 2 causes the air pressure in the gas purification box 3 to drop. At this time, the air pressure in the gas purification box 3 is lower than the air pressure in the collection box 19, creating an airflow from the collection box 19 to the gas purification box 3. This also makes the air pressure in the collection box 19 lower than the air pressure in the spray box 1, thereby drawing the exhaust gas generated in the spray box 1 and the dust on the casting to the collection box 19 through the fourth connecting pipe 22. The filter plate 20 in the collection box 19 filters the dust. The air passes through the filter plate 20 and the third connecting pipe 21 and enters the gas purification box 3. The gas purification box 3 purifies the air, forming an air circulation.
