Description

Technical Field

[0001] This utility model belongs to the field of anti-corrosion coating spraying technology, and in particular relates to an automatic spraying equipment for anti-corrosion coating of condenser tube sheet. Background Technology

[0002] The condenser tube sheet is the core component of the condenser. It is used to divide the internal structure of the shell and support the tube bundle, while separating the steam condensation zone from the inlet and outlet water chambers of the circulating cooling water. During its production and processing, an anti-corrosion coating needs to be sprayed on its surface to extend its service life.

[0003] Chinese patent disclosure CN221183341U discloses an automatic anti-corrosion coating device, which "belongs to the field of coating spraying technology and aims to solve the problem that existing technologies for spraying metal sheets are mostly limited to spraying only one side, and the amount of coating sprayed at one time is limited, requiring multiple orientation and rotation of the sheet to complete the spraying." The device includes a base platform and a coating platform. The base platform is located below the coating platform, and a movable main box is located above the coating platform. A return conduit connects the main box and the coating platform. The upper surface of the coating platform is recessed, and the recess has return holes. The bottom end of the main box has upper spray nozzles arranged in a straight line. The main box has an inverted U-shaped structure, and movable boxes are installed on the two inner side walls of the bottom. Movable spray nozzles are installed on the inner walls of the movable boxes. The upper surface of the coating platform has two sets of symmetrically distributed fixed plates. This automatic anti-corrosion coating device can perform multi-directional synchronous spraying operations on metal sheets without requiring multiple orientations, resulting in high spraying efficiency.

[0004] However, the above scheme is inconvenient for dual-station spraying. When spraying the tube sheet, it is necessary to wait for the spraying to be completed before the other tube sheet can be unloaded and placed. This waiting time during spraying wastes time and results in low overall spraying efficiency. Therefore, it is necessary to design an automatic spraying equipment for condenser tube sheet anti-corrosion coating. Utility Model Content

[0005] This utility model provides an automatic spraying equipment for anti-corrosion coating of condenser tube sheets, which aims to solve the problem that some currently used automatic spraying equipment is inconvenient to perform dual-station spraying processing.

[0006] This utility model is implemented as follows: an automatic spraying device for anti-corrosion coating of condenser tube sheets includes a machine body; a through groove formed at the lower end of the front side of the machine body, with a controller fixedly connected to the lower end of one side of the machine body; a shielding assembly mounted on the front side of the machine body, which is used to shield the through groove during spraying; a discharge pipe fixedly connected to the lower end of the back side of the machine body, with a placement frame provided on the machine body and the through groove; a rotating assembly mounted on one side of the bottom wall of the machine body, which is used to rotate the placement frame; Z-axis electric slide rails symmetrically fixedly connected to the top wall of the machine body, with X-axis electric slide rails slidably connected between the Z-axis electric slide rails, a fixed cylinder slidably connected to the bottom end of the X-axis electric slide rails, a rotating frame fixedly connected to the output end of the fixed cylinder, a spray head rotatably connected to the inner wall of the rotating frame, and a stepper motor connected to the spray head fixedly connected to one side of the rotating frame.

[0007] Preferably, the rotating assembly includes: a fixed base fixedly connected to one side of the bottom wall of the machine body, a drive motor fixedly connected to the inner bottom wall of the fixed base, and the output end of the drive motor fixedly connected to the bottom end of the placement frame through a coupling.

[0008] Preferably, the top of the fixed base is provided with a limiting groove, and the bottom of the placement frame is fixedly connected with a limiting block that slides in the limiting groove.

[0009] Preferably, a discharge groove is provided on one side of the bottom wall of the limiting ring groove, and the discharge groove is arc-shaped.

[0010] Preferably, the length of the through groove is greater than the diameter of the rotation circumference of the placement rack, and the top of the placement rack is provided with anti-slip textures at equal intervals.

[0011] Preferably, the shielding assembly includes: a fixed plate symmetrically fixedly connected to the upper end of one side of the machine body; and a lifting cylinder fixedly connected to the top of the fixed plate, wherein the output end of the lifting cylinder passes through the fixed plate and is fixedly connected to the shielding plate.

[0012] Preferably, a slider is fixedly connected to the upper end of one side of the baffle, a sliding groove is provided on one side of the machine body to slide with the slider, and a groove is provided at the middle position of the bottom end of the baffle.

[0013] Preferably, a guide plate is fixedly connected to the inner bottom wall of the machine body, and the top of the guide plate is tilted at an angle of fifteen degrees to the horizontal direction.

[0014] Compared with related technologies, the automatic spraying equipment for anti-corrosion coating of condenser tube sheets provided by this utility model has the following beneficial effects: By starting the drive motor to rotate the placement rack, the placement rack can rotate smoothly. When the placement rack is perpendicular to the through slot, the top of the placement rack inside the machine body can be placed on the tube sheet for spraying. The other part of the placement rack rotates to the outside of the machine body for easy access to the tube sheet, realizing dual-station spraying operation. This avoids the low spraying efficiency caused by waiting for spraying time in the traditional method and improves its practicality.

[0015] During spraying, the lifting cylinder can be activated to lower the shielding plate to block the channel, preventing the sprayed anti-corrosion coating from splashing out of the channel. After spraying is completed, the lifting cylinder can be activated to raise the shielding plate to fully expose the channel, facilitating the normal rotation of the placement frame. This allows for a more enclosed spraying operation and reduces the splashing of anti-corrosion coating. Attached Figure Description

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments. Example 1

[0020] A preferred embodiment of the automatic spraying equipment for anti-corrosion coating of condenser tube sheets provided by this utility model is, for example... Figures 1 to 5 As shown: An automatic spraying device for anti-corrosion coating of condenser tube sheet includes a body 1; a through groove 14 opened at the lower end of the front of the body 1, and a controller 3 fixedly connected to the lower end of one side of the body 1; a shielding component 2 mounted on the front of the body 1, which is used to shield the through groove 14 during spraying; a discharge pipe 11 fixedly connected to the lower end of the back of the body 1, and a placement frame 4 is provided on the body 1 and the through groove 14; a rotating component 12 mounted on one side of the inner bottom wall of the body 1, which is used to realize the rotation of the placement frame 4; Z-axis electric slide rails 8 symmetrically fixedly connected to the inner top wall of the body 1, X-axis electric slide rails 6 slidably connected between the Z-axis electric slide rails 8, a fixed cylinder 7 slidably connected to the bottom end of the X-axis electric slide rails 6, a rotating frame 9 fixedly connected to the output end of the fixed cylinder 7, a spray head 10 rotatably connected to the inner wall of the rotating frame 9, and a stepper motor connected to the spray head 10 fixedly connected to one side of the rotating frame 9.

[0021] It should be noted that some existing automatic spraying equipment for anti-corrosion coating of condenser tube sheets still has certain shortcomings in actual use. When spraying tube sheets, it is necessary to wait for the spraying to be completed before the material can be cut and another tube sheet can be placed. However, this requires waiting during the spraying process, which wastes this time and results in low overall spraying efficiency.

[0022] In a further preferred embodiment of the present invention, the rotating assembly 12 includes: a fixed seat 1204 fixedly connected to one side of the inner bottom wall of the body 1, a drive motor 1205 fixedly connected to the inner bottom wall of the fixed seat 1204, and the output end of the drive motor 1205 fixedly connected to the bottom end of the placement frame 4 through a coupling.

[0023] In this embodiment, the drive motor 1205 is started to drive the placement rack 4 to rotate, so that the placement rack 4 can rotate smoothly. When the placement rack 4 is perpendicular to the through groove 14, the top of the placement rack 4 inside the machine body 1 can be placed on the tube sheet for spraying, while the other part of the placement rack 4 rotates to the outside of the machine body 1 to facilitate normal picking up and taking of the tube sheet, thus realizing dual-station spraying operation.

[0024] In a further preferred embodiment of the present invention, a limiting ring groove 1203 is formed at the top of the fixed base 1204, and a limiting block 1202 that slides and engages with the inside of the limiting ring groove 1203 is fixedly connected at the bottom of the placement frame 4 at an equal angle.

[0025] In this embodiment, the sliding of the limiting block 1202 inside the limiting ring groove 1203 improves the rotational stability of the placement rack 4 and avoids the entire weight of the placement rack 4 being applied to the output end of the drive motor 1205.

[0026] In a further preferred embodiment of the present invention, a discharge groove 1201 is provided on one side of the inner bottom wall of the limiting ring groove 1203, and the shape of the discharge groove 1201 is arc-shaped.

[0027] In this embodiment, the discharge groove 1201 allows a small amount of anti-corrosion coating that has entered the limiting ring groove 1203 to be discharged more easily through the discharge groove 1201.

[0028] In a further preferred embodiment of this utility model, the length of the through groove 14 is greater than the diameter of the rotation circumference of the placement rack 4, and the top of the placement rack 4 is provided with anti-slip textures 5 at equal intervals.

[0029] In this embodiment, the anti-slip texture 5 is used to improve the anti-slip stability of the tube sheet placed on the top of the placement rack 4. Example 2

[0030] Based on Example 1, a preferred embodiment of the automatic spraying equipment for anti-corrosion coating of condenser tube sheets provided by this utility model is as follows: Figures 1 to 5 As shown: The shielding component 2 includes: a fixed plate 202 symmetrically fixedly connected to the upper end of one side of the body 1; a lifting cylinder 203 fixedly connected to the top of the fixed plate 202, the output end of the lifting cylinder 203 passing through the fixed plate 202 and fixedly connected to the shielding plate 201.

[0031] In this embodiment, during spraying, the lifting cylinder 203 can be activated to lower the shielding plate 201 to shield the through groove 14, preventing the sprayed anti-corrosion coating from splashing out of the through groove 14. After spraying is completed, the lifting cylinder 203 can be activated to raise the shielding plate 201 to fully expose the through groove 14, facilitating the normal rotation of the placement rack 4.

[0032] In a further preferred embodiment of the present invention, a slider 205 is fixedly connected to the upper end of one side of the baffle plate 201, a groove 204 is provided on one side of the body 1 to slide and cooperate with the slider 205, and a groove is provided at the middle position of the bottom end of the baffle plate 201.

[0033] In this embodiment, the sliding of the slider 205 inside the groove 204 is used to improve the smoothness of the up-and-down sliding of the baffle plate 201.

[0034] In a further preferred embodiment of this utility model, a guide plate 13 is fixedly connected to the inner bottom wall of the body 1, and the top of the guide plate 13 is inclined at an angle of fifteen degrees to the horizontal direction.

[0035] In this embodiment, the inclined guide plate 13 is used to allow excess anti-corrosion coating to be discharged more smoothly and centrally through the discharge pipe 11.

[0036] In summary, the tube sheet is placed on one side of the top of the placement rack 4, and then the drive motor 1205 is started to drive the placement rack 4 to rotate. The limit block 1202 slides inside the limit ring groove 1203, so that the placement rack 4 can rotate smoothly. When the placement rack 4 is perpendicular to the through groove 14, part of the placement rack 4 will be inside the machine body 1, and the other part will be outside the machine body 1. Thus, the tube sheet inside the machine body 1 can be sprayed, while the tube sheet can be picked up and removed normally outside, realizing dual-station spraying. When the placement frame 4 rotates to place the tube sheet inside the machine body 1, the lifting cylinder 203 can be activated to lower the baffle plate 201 to block the through groove 14. Then, when spraying inside the machine body 1, the spray head 10 can slide left and right and back and forth using the X-axis electric slide rail 6 and the Z-axis electric slide rail 8. The fixed cylinder 7 can make the spray head 10 slide up and down, which makes it easy to move the spray head 10 to a suitable height at the top of the tube sheet. The stepper motor on the rotating frame 9 can be used to change the tilt angle of the spray head 10, so as to adjust the paint spraying angle. After one of the tube sheets is sprayed, the lifting cylinder 203 can be activated to raise the shield 201 and fully expose the through groove 14. Then the placement rack 4 can be rotated normally. At the same time, the excess anti-corrosion coating can be guided by the guide plate 13 so that it can be discharged more smoothly and centrally through the discharge pipe 11, making it easier to recycle.
