[0020] Embodiment

[0021] Please refer to Figures 1-4 As shown, the present utility model provides an impregnating device for the production of a centrifugal pump casing, including a base 1. A tank body 2 is arranged at the top end of the base 1. A frame body 5 is arranged between the two ends at the top of the tank body 2. A lifting electric cylinder 8 penetrates through the middle position at the top end of the frame body 5. A lifting seat 7 is arranged inside the frame body 5 at the bottom end of the lifting electric cylinder 8. A servo motor 9 is arranged at the bottom end of the lifting seat 7. A positioning groove 14 is arranged at the output end of the servo motor 9. Clamping electric cylinders 18 are arranged on both sides inside the positioning groove 14. A loading clamping plate 19 is arranged on one side of the clamping electric cylinder 18. The clamping electric cylinders 18 are symmetrically arranged inside the positioning groove 14. The loading clamping plates 19 are parallel to each other. The pump casing is clamped by pushing the loading clamping plates 19 towards each other through the clamping electric cylinders 18. When the pump casing is subjected to impregnating treatment, the pump casing is pushed down by the lifting electric cylinder 8 and immersed in the paint in the tank body 2. At the same time, the positioning groove 14 is driven to rotate by the servo motor 9, that is, the pump casing is driven to rotate, so as to make the impregnating more uniform. A discharge port 12 is inserted at the bottom of the rear end of the tank body 2. A baking lamp 10 is arranged at the top of the rear end inside the tank body 2. After the impregnating is completed, the pump casing is lifted by the lifting electric cylinder 8, and at the same time, the baking lamp 10 is turned on to bake and dry the paint on the surface of the pump casing;

[0022] As a further implementation manner of this embodiment, as Figure 1 、 Figure 2 and Figure 3 As shown, a dust collection box 15 is arranged at the middle position near the top on one side of the tank body 2. A filter bag is arranged inside the dust collection box 15. A negative pressure dust suction fan 16 is arranged at the bottom end of the dust collection box 15. An L-shaped dust conveying pipe 6 is inserted at the top end of the dust collection box 15. A dust suction slot opening 4 is arranged on one side inside the frame body 5. One end of the dust conveying pipe 6 penetrates through one side of the frame body 5 and is fixedly connected to the middle position on one side of the dust suction slot opening 4, and the dust conveying pipe 6 is communicated with the dust suction slot opening 4. The negative pressure dust suction fan 16 is started to suck the dust outside the pump casing into the dust collection box 15 through the dust suction slot opening 4 and the dust conveying pipe 6 for filtration and collection. At the same time, the outside of the centrifugal pump casing can be comprehensively dusted and cleaned through the cooperation of the servo motor 9, so as to avoid the dust remaining outside the centrifugal pump casing being covered under the paint surface and affecting the impregnating effect on the surface of the pump casing;

[0023] Before the centrifugal pump casing is immersed in the paint in the tank body 2, the negative pressure dust suction fan 16 is started to suck the dust outside the pump casing into the dust collection box 15 through the dust suction slot opening 4 and the dust conveying pipe 6 for filtration and collection. At the same time, the outside of the centrifugal pump casing can be comprehensively dusted and cleaned through the cooperation of the servo motor 9;

[0024] As a further implementation manner of this embodiment, as Figures 1-4As shown in the figure, a protection component is arranged at a position near the top between the inner side walls of the tank body 2. The protection component includes a protection baffle 11. The protection baffle 11 penetrates through the top of the other side of the tank body 2. An opening and closing electric cylinder 3 is arranged at the top of the front end of the tank body 2. Stable sliding grooves 17 are arranged at positions near the top at both ends inside the tank body 2. A connecting plate 13 is arranged on one side of the protection baffle 11. The front end of one side of the connecting plate 13 is fixedly connected to one side of the opening and closing electric cylinder 3. Both ends of the protection baffle 11 are clamped into the inside of the stable sliding grooves 17. Starting the opening and closing electric cylinder 3 can drive the protection baffle 11 to open and close through the connecting plate 13. When the surface of the pump casing is not subjected to dip painting, closing the protection baffle 11 can seal the tank body 2, effectively avoiding dust and foreign objects from entering the tank body 2 and contaminating the paint when the pump casing is not dip painted, which affects the dip painting effect of the subsequent device on the surface of the pump casing. When the pump casing needs to be dip painted, the protection baffle 11 can be pushed outward by the opening and closing electric cylinder 3. Moreover, both ends of the protection baffle 11 can slide horizontally in the stable sliding grooves 17, and the stable sliding grooves 17 can stabilize the protection baffle 11 during the horizontal movement of opening and closing.

[0025] When the surface of the pump casing is not subjected to dip painting, the opening and closing electric cylinder 3 drives the protection baffle 11 to move towards the inner side of the tank body 2 through the connecting plate 13, and the tank body 2 is sealed by the protection baffle 11 to prevent dust and foreign objects from entering the tank body 2 and contaminating the paint. When the pump casing is dip painted, the protection baffle 11 can be pushed outward by the opening and closing electric cylinder 3.

[0026] Specific working principle:

[0027] When using the dip painting device, the clamping electric cylinder 18 is used to push the loading clamping plates 19 towards each other to clamp the pump casing. Subsequently, the negative pressure dust suction fan 16 is started, and the dust outside the pump casing is sucked through the dust suction slot 4 into the dust collection box 15 through the dust conveying pipe 6 for filtering and collection. At the same time, the servo motor 9 is used to drive the pump casing to rotate, so that the outside of the centrifugal pump casing can be comprehensively dusted. After dust removal treatment on the surface of the pump casing, the opening and closing electric cylinder 3 is started to push the protection baffle 11 outward. Subsequently, the lifting electric cylinder 8 is started to push the pump casing down and immerse it in the paint in the tank body 2. At the same time, the servo motor 9 is started to drive the positioning groove 14 to rotate, which drives the pump casing to rotate, making the dip painting more uniform. After dip painting, the pump casing is lifted by the lifting electric cylinder 8, and at the same time, the baking lamp 10 is turned on to dry the paint on the surface of the pump casing. After dip painting treatment on the surface of the pump casing, the opening and closing electric cylinder 3 drives the protection baffle 11 to move towards the inner side of the tank body 2 through the connecting plate 13, and the tank body 2 is sealed by the protection baffle 11 to prevent dust and foreign objects from entering the tank body 2 and contaminating the paint.
