Description

Technical Field

[0001] This invention relates to the field of heat tracing pipe processing, and more specifically, to a spray-type heat tracing pipe anti-corrosion coating application device and its application method. Background Technology

[0002] In industries such as petroleum, chemical, and power, heat tracing pipes are key components for maintaining the temperature of transported media. They operate in harsh environments with high temperature, high humidity, and corrosive media for extended periods. Their outer walls are highly susceptible to corrosion and damage, which not only shortens the service life of the heat tracing pipes but may also lead to safety hazards such as media leakage. Therefore, applying an anti-corrosion coating to the outer wall of the heat tracing pipes is an important step in ensuring the safe and stable operation of industrial production.

[0003] Currently, the application of anti-corrosion coatings on heat tracing pipes (the coating is applied to the outer wall of the heat tracing pipe) is mostly done manually or with traditional spraying equipment. Manual application has problems such as low coating efficiency and high labor intensity, making it difficult to meet the needs of large-scale industrial production. Moreover, traditional spraying equipment is mostly designed with fixed dimensions and lacks modular adjustment capabilities for heat tracing pipes of various specifications. It can only be adapted to heat tracing pipes of a single length, and switching specifications requires significant adjustments to the equipment (requiring disassembly and reassembly of the core components), resulting in poor practicality.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a spray-type heat tracing pipe anti-corrosion coating application device and its usage method. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a spray-type heat tracing pipe anti-corrosion coating application device and its application method.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spray-type heat tracing pipe anti-corrosion coating application device, comprising: Top plate, used to mount the coating equipment entirely on the factory roof; The rotating fixing mechanism includes an electric three-grip chuck A driven by a motor A, and an electric three-grip chuck B rotated and supported by a rotating support assembly. The electric three-grip chuck A and the electric three-grip chuck B are arranged opposite to each other, and their clamping centers are collinear and at the same horizontal height, for clamping both ends of the heat tracing pipe. The length adjustment component is connected to motor A and the rotating support component at both ends, respectively. It is used to adjust the distance between motor A and the rotating support component, and ultimately adjust the distance between electric three-jaw chuck A and electric three-jaw chuck B, so as to adapt to the clamping of heat tracing pipes of different lengths. The spraying mechanism is connected to the bottom of the top plate via a connecting plate A, and the spraying direction is aligned with the outer wall of the heat tracing pipe clamped between the electric three-grip chuck A and the electric three-grip chuck B. The reciprocating mechanism, also installed at the bottom of the top plate, drives the length adjustment component to move back and forth, ultimately causing the heat tracing pipe clamped between the electric three-grip chuck A and the electric three-grip chuck B to move back and forth, thereby spraying the outer wall of the heat tracing pipe comprehensively.

The top of the outer rod is fixedly connected to screws on both sides of the through groove, the fixing plate has through holes for the screws to pass through, and a nut is threaded onto the outer side wall of the screw.

[0009] Preferably, the rotating support assembly includes a bearing seat fixed to the bottom of the connecting plate C, and a bearing A is installed on the bearing seat. A rotating rod A is fixedly connected to the inner ring of the bearing A, and the head of the rotating rod A is connected to the electric three-jaw chuck B.

[0010] Preferably, the reciprocating mechanism includes a lower open shell fixed to the bottom of the top plate, and a lead screw driven by a motor B is installed inside the lower open shell. The end of the lead screw is rotatably connected to the inner side of the lower open shell through a bearing B. A rod sleeve is threaded onto the outer wall of the lead screw, and the bottom end of the rod sleeve is connected to the outer rod through a vertical rod B.

[0011] Preferably, a guide rail C is installed on the inner top wall of the lower opening shell, and the top end of the rod sleeve is slidably connected to the guide rail C by a slider C.

[0012] Preferably, the spraying mechanism includes a storage tank connected to the end of the connecting plate A. The top of the storage tank is equipped with a top cover, and the bottom of the storage tank is connected to an infusion pipe via a booster pump. A valve is installed on the infusion pipe, and an electric spray head is installed at the end of the infusion pipe. The spraying direction of the electric spray head is aligned with the outer wall of the heat tracing pipe clamped between the electric three-grip chuck A and the electric three-grip chuck B.

[0013] Preferably, the top cover is equipped with a stirring assembly for continuously stirring the anti-corrosion coating material inside the storage tank.

[0014] Preferably, the stirring assembly includes a bearing C embedded and fixed at the center of the top of the top cover, and a rotating rod B is fixedly connected to the inner ring of the bearing C. The side end of the top cover is connected to a motor C through a connecting frame, and the rotating rod B is driven by the motor C. An annular toothed plate is fixedly connected to the inner side wall of the top cover. A rotating plate is fixedly connected to the bottom end of the rotating rod B, and a gear that meshes with the annular toothed plate is rotatably connected to the bottom end of the rotating plate through a bearing D. A stirring paddle is fixedly connected to the center of the bottom end of the gear.

[0015] The method for applying the above-mentioned spray-type heat tracing pipe anti-corrosion coating device includes the following steps: S1: Device installation; S1.1: Install and fix the top plate to the pre-set installation position on the roof of the factory building using bolts and other fasteners (install the device above the paint recycling tank), ensuring that the top plate is level and stable; S2: Heat tracing pipe length adaptation adjustment S2.1: Loosen the nut on the screw in the length adjustment assembly, move the fixing plate upward, and drive the protrusion to slide upward along the guide rail B, so that the protrusion is dislodged from the groove of the inner rod and disengaged from the through groove of the outer rod; S2.2: Based on the actual length of the heat tracing pipe to be sprayed, push the inner rod so that it slides smoothly along the guide rail A inside the outer rod through the slider A, and simultaneously drive the electric three-grip chuck B to move, and adjust the distance between the electric three-grip chuck A and the electric three-grip chuck B to the appropriate length. S2.3: Move the fixed plate downwards so that it slides down along the guide rail B via the slider B, causing the protrusion to pass through the through groove of the outer rod and insert into the corresponding groove of the inner rod until the fixed plate is tightly attached to the top surface of the outer rod; S2.4: Insert the nut into the screw and tighten it.

S3: Heat tracing pipe clamping and spraying operation S3.1: Place both ends of the heat tracing pipe to be sprayed into the clamping areas of electric three-jaw chuck A and electric three-jaw chuck B respectively, and start the clamping function of the two chucks to stably clamp both ends of the heat tracing pipe. S3.2: Simultaneously start the motor A of the rotating fixing mechanism and the motor B of the reciprocating mechanism. Motor A drives the electric three-grip chuck A to rotate. Through the cooperation of the rotating rod A and the bearing A, the electric three-grip chuck B is driven to rotate synchronously, so that the heat tracing tube rotates at a uniform speed. Motor B drives the lead screw to rotate through forward and reverse rotation, which drives the rod sleeve and length adjustment component to make linear reciprocating motion, thereby driving the heat tracing tube to move back and forth. S3.3: Open the valve on the infusion tube, start the booster pump, adjust the valve opening to control the paint delivery flow rate, so that the paint is delivered to the electric nozzle through the infusion tube, start the electric nozzle, and spray the pressurized paint into atomized form onto the surface of the heat tracing pipe. Through the coordinated operation of the rotation and axial reciprocating movement of the heat tracing pipe, the outer wall is fully and uniformly coated.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The length adjustment component in this invention, through a sliding adjustment structure and an insertion locking structure, can quickly adapt to heat tracing pipes of different lengths without disassembling and reassembling the core components, thus solving the problem that traditional equipment can only adapt to a single length and that switching specifications is cumbersome. 2. The present invention uses the upper mechanism of the device to rotate and reciprocate the heat tracing pipe, and in conjunction with the directional spraying of the spraying mechanism, it can comprehensively and uniformly spray the outer wall of the heat tracing pipe, replacing manual brushing, greatly improving coating efficiency, reducing labor intensity, and meeting the needs of large-scale industrial production. 3. The present invention can effectively prevent pigments, fillers, curing agents and other components in the coating from settling, layering or agglomerating due to long-term standing by the stirring component, so as to ensure that the coating system always maintains a uniform and stable concentration and viscosity, thereby ensuring the quality of subsequent spraying. 4. The present invention enables the stirring paddle to achieve a composite motion of "revolution + rotation" through the cooperation of the components on the stirring assembly. This motion mode enables the anti-corrosion coating in the storage tank to be continuously stirred in all directions without dead angles, achieving a good stirring effect.

[0019] Example 1 like Figures 1 to 5 As shown, the present invention provides a spray-type heat tracing pipe anti-corrosion coating application device, comprising: Top plate 1, used to install the coating device as a whole on the roof of the factory building; The rotating fixing mechanism 2 includes an electric three-jaw chuck A202 driven by a motor A201 and an electric three-jaw chuck B204 rotated and supported by a rotating support assembly 203. The electric three-jaw chuck A202 and the electric three-jaw chuck B204 are arranged opposite to each other, and their clamping centers are collinear and at the same horizontal height. They are used to clamp the two ends of the heat tracing pipe. The rotating support assembly 203 includes a bearing seat 2031 fixed to the bottom of the connecting plate C306, and a bearing A2032 is installed on the bearing seat 2031. A rotating rod A2033 is fixedly connected to the inner ring of the bearing A2032, and the head of the rotating rod A2033 is connected to the electric three-jaw chuck B204. The length adjustment component 3, with its two ends connected to the motor A201 and the rotary support component 203 respectively, is used to adjust the distance between the motor A201 and the rotary support component 203, and ultimately adjust the distance between the electric three-jaw chuck A202 and the electric three-jaw chuck B204, thereby adapting to the clamping of heat tracing pipes of different lengths. The length adjustment component 3 includes an outer rod 301 with one open end. Guide rails A302 for sliding sliders A303 are installed on both sides inside the outer rod 301, and an inner rod 304 is fixedly connected between the sliders A303. The inner rod 304 extends out of the outer rod 301 through the opening of the outer rod 301. The end of the outer rod 301 away from the inner rod 304 is connected to the motor A201 through a connecting plate B305, and the end of the inner rod 304 away from the outer rod 301 is connected to the motor A201 through a connecting plate C. 306 is connected to the rotary support assembly 203. The top of the outer rod 301 near the opening is provided with a through groove 3011. The top of the inner rod 304 is provided with multiple grooves 3041 arranged in a horizontal array. The front and rear sides of the outer rod 301 near the opening are both equipped with guide rails B307 for sliding slider B308. The top of the slider B308 is fixedly connected to a fixing plate 310 through a vertical rod A309. The bottom end of the fixing plate 310 is fixedly connected to a protrusion 311 that can pass through the through groove 3011 and be inserted into the corresponding groove 3041. The top of the outer rod 301 is fixedly connected to both sides of the through groove 3011. The fixing plate 310 is provided with a through hole 3101 for the screw 312 to pass through, and a nut is threaded on the outer side wall of the screw 312. The spraying mechanism 4 is connected to the bottom of the top plate 1 via the connecting plate A5, and the spraying direction is aligned with the outer wall of the heat tracing pipe clamped between the electric three-grip chuck A202 and the electric three-grip chuck B204. The reciprocating mechanism 6, which is also installed at the bottom of the top plate 1, is used to drive the length adjustment component 3 to move back and forth, and ultimately drive the heat tracing pipe clamped between the electric three-grip chuck A202 and the electric three-grip chuck B204 to move back and forth, thereby spraying the outer wall of the heat tracing pipe in a comprehensive manner.

[0020] Top plate 1 fixes the coating device to the roof of the factory building. Spraying mechanism 4 is installed at the bottom of top plate 1 via connecting plate A5. Reciprocating mechanism 6 is also fixed at the bottom of top plate 1 and connected to length adjustment component 3. In rotating fixing mechanism 2, motor A201 is connected to outer rod 301 of length adjustment component 3 via connecting plate B305. Bearing seat 2031 of rotating support component 203 is connected to inner rod 304 of length adjustment component 3 via connecting plate C306. When it is necessary to adjust the distance between electric three-jaw chuck A202 and electric three-jaw chuck B204, the inner rod 304 is pushed. The inner rod 304 slides along the guide rail A302 inside the outer rod 301 via the slider A303. After adjusting the distance between the electric three-jaw chuck A202 and the electric three-jaw chuck B204 to match the length of the heat tracing pipe to be sprayed, the fixing plate 310 moves downward. The fixing plate 310 moves along the guide rail B307 via the slider B308, so that the protrusion 311 passes through the through groove 3011 of the outer rod 301 and inserts into the corresponding groove 3041 of the inner rod 304. After the protrusion 311 is inserted into the groove 3041, the fixing plate 310 is tightly attached to the top surface of the outer rod 301, and the screw 312 passes through the fixing plate 310. The through hole 3101 on plate 310 is then installed on the screw 312 and tightened to fix the protrusion 311 in the groove 3041, thereby completing the fixation between the outer rod 301 and the inner rod 304. This enables rapid adjustment of the distance between the electric three-grip chuck A202 and the electric three-grip chuck B204 (adjustment is considered complete only after the position is fixed). Subsequently, the two chucks stably clamp both ends of the heat tracing pipe. During spraying, motor A201 drives the electric three-grip chuck A202 to rotate, while the rotating rod A2033 cooperates with the bearing A2032 to make the electric three-grip chuck B204 rotate. 4. Synchronous rotation (when the electric three-grip chuck B204 rotates, it will drive the rotation of the rotating rod A2033, which in turn drives the inner ring of the bearing A2032 to rotate. The inner ring rotates along with the outer ring, thus providing rotational support for the electric three-grip chuck B204), causing the heat tracing pipe to rotate at a uniform speed. The reciprocating mechanism 6 drives the length adjustment component 3 to move the clamped heat tracing pipe back and forth. The spraying mechanism 4 simultaneously sprays anti-corrosion coating onto the outer wall of the heat tracing pipe. Finally, through the combination of rotation and reciprocation, the outer wall of the heat tracing pipe is fully and evenly sprayed, completing the coating operation of the anti-corrosion coating of the heat tracing pipe.

[0021] Among them, the length adjustment component 3 can quickly adapt to heat tracing pipes of different lengths without disassembling and reassembling the core components through the sliding adjustment structure and the insertion locking structure. This solves the problem that traditional equipment can only adapt to a single length and the specification switching is cumbersome. The coordinated operation of the heat tracing pipe's rotation and reciprocating movement, as well as the directional spraying of the spraying mechanism 4, replaces manual brushing, greatly improving coating efficiency, reducing labor intensity, and meeting the needs of large-scale industrial production.

[0022] Remove the nut from the screw 312, move the fixing plate 310 upward, and drive the protrusion 311 to slide upward along the guide rail B307, so that the protrusion 311 disengages from the groove 3041 of the inner rod 304 and disengages from the through groove 3011 of the outer rod 301. Then push the inner rod 304 to readjust the distance between the electric three-grip chuck A202 and the electric three-grip chuck B204.

[0023] Example 2 like Figure 1 , Figure 2 , Figure 3 as well as Figure 6 - Figure 10 As shown in the figure, this embodiment provides the specific structure of the reciprocating mechanism 6 and the spraying mechanism 4 in embodiment 1: The reciprocating mechanism 6 includes a lower opening shell 601 fixed to the bottom of the top plate 1, and a lead screw 603 driven by a motor B602 is installed inside the lower opening shell 601. The end of the lead screw 603 is rotatably connected to the inner side of the lower opening shell 601 through a bearing B608. A rod sleeve 604 is threadedly connected to the outer wall of the lead screw 603. The bottom end of the rod sleeve 604 is connected to the outer rod 301 through a vertical rod B607. A guide rail C605 is installed on the inner top wall of the lower opening shell 601. The top end of the rod sleeve 604 is slidably connected to the guide rail C605 through a slider C606. After motor B602 starts, it drives lead screw 603 (bearing B608 is used to rotate and support lead screw 603 to ensure the stability of lead screw 603 rotation). The controller controls the forward or reverse rotation of motor B602 (and controls the time of forward or reverse rotation of motor B602 according to the length of heat tracing pipe), thereby driving lead screw 603 to rotate forward or reverse. The sleeve 604, which is threaded to lead screw 603, is guided and limited by the top slider C606 sliding along the guide rail C605 on the inner top wall of the lower opening shell 601. This converts the rotational motion of lead screw 603 into smooth linear reciprocating motion, which in turn drives the back and forth movement of outer rod 301 connected to it through vertical rod B607. Finally, it drives the heat tracing pipe clamped between electric three-jaw chuck A202 and electric three-jaw chuck B204 to move back and forth.

[0024] The spraying mechanism 4 includes a storage tank 401 connected to the end of the connecting plate A5. The top of the storage tank 401 is equipped with a top cover 402. The bottom of the storage tank 401 is connected to the infusion pipe 404 via a booster pump 403. A valve 406 is installed on the infusion pipe 404. An electric nozzle 405 is installed at the end of the infusion pipe 404. The spraying direction of the electric nozzle 405 is aligned with the outer wall of the heat tracing pipe clamped between the electric three-grip chuck A202 and the electric three-grip chuck B204. First, the storage tank 401 (detachably connected to the connecting plate A5 via screws) serves as the storage container for the anti-corrosion coating. Its top cover 402 can be opened flexibly, allowing workers to easily replenish the coating or change to different types of anti-corrosion coatings. After replenishment, closing the top cover 402 prevents contamination of the coating by external dust and impurities, while also reducing coating evaporation loss. Before starting the spraying operation, valve 406 on the infusion pipe 404 must be opened to facilitate coating delivery. Then, the booster pump 403 is started. Connected to the bottom of the storage tank 401 via pipeline, the booster pump 403 accurately extracts the anti-corrosion coating stored in the tank and pressurizes it. The pressurized coating receives sufficient delivery power, providing a pressure basis for the subsequent atomization effect of the electric spray head 405. The pressurized anti-corrosion coating is stably delivered along the infusion pipe 404. During the process, the valve 406 can be finely adjusted according to spraying requirements, thereby regulating the coating's viscosity. The flow rate is controlled to prevent paint buildup due to excessive flow or discontinuous spraying due to insufficient flow. Finally, the paint is delivered to the electric nozzle 405 at the end of the infusion tube 404. After the electric nozzle 405 is activated, it atomizes the pressurized paint into fine and uniform paint particles. Because its spray direction is preset to be aligned with the outer wall of the heat tracing pipe clamped between the electric three-grip chuck A202 and the electric three-grip chuck B204, the atomized paint particles can be accurately sprayed onto the surface of the heat tracing pipe. With the rotation and reciprocating movement of the heat tracing pipe, a comprehensive and uniform coating of the outer wall of the heat tracing pipe is achieved.

[0025] Furthermore, the top cover 402 is equipped with a stirring assembly 7 for continuously stirring the anti-corrosion coating material in the storage tank 401. This effectively prevents pigments, fillers, curing agents, and other components in the coating from settling, stratifying, or agglomerating due to prolonged standing, ensuring that the coating system maintains a uniform and stable concentration and viscosity, thereby guaranteeing the subsequent spraying quality. The specific structure of the stirring assembly 7 is as follows: The stirring assembly 7 includes a bearing C701 embedded and fixed in the center of the top of the top cover 402, and a rotating rod B702 is fixedly connected to the inner ring of the bearing C701. The side end of the top cover 402 is connected via... The connecting frame 703 is connected to the motor C704, which drives the rotating rod B702. An annular toothed plate 705 is fixedly connected to the inner wall of the top cover 402. A rotating plate 706 is fixedly connected to the bottom end of the rotating rod B702. The bottom end of the rotating plate 706 is rotatably connected to a gear 707 that meshes with the annular toothed plate 705 via a bearing D709. A stirring paddle 708 is fixedly connected to the center of the bottom end of the gear 707. The stirring assembly 7 is installed on the top cover 402. The stirring assembly 7 can be removed by disassembling the top cover 402, making it easy to clean.

[0026] Motor C704 is fixed to the side of top cover 402 via connecting bracket 703. After starting, it drives the rotating rod B702, which is embedded and fixed to the inner ring of the central bearing C701 at the top of top cover 402, to rotate. (When the rotating rod B702 rotates, it drives the inner ring of bearing C701 to rotate, and the inner ring rotates along with its outer ring, thus providing rotational support for the rotating rod B702 through bearing C701.) The rotating rod B702 drives the rotation of the rotating plate 706 at the bottom. The bottom of the rotating plate 706 is connected to the rotating plate 706 via bearing D709. The gear 707 meshes with the annular toothed plate 705 fixed to the inner wall of the top cover 402. While revolving with the rotating plate 706, it also rotates on its own axis, thereby driving the stirring paddle 708 fixed at the bottom center of the gear 707 to achieve a compound motion of "revolution + rotation". Through this motion, the anti-corrosion coating in the storage tank 401 is continuously stirred in all directions without dead angles, effectively preventing the pigments, fillers, curing agents and other components in the coating from settling, separating or agglomerating, and ensuring that the concentration and viscosity of the coating system are uniform and stable.

[0027] It should be noted that motors A201, B602, and C704 are all equipped with speed reducers.

[0028] The present invention also provides a method for using the above-mentioned spray-type heat tracing pipe anti-corrosion coating application device: S1: Device installation; S1.1: Install and fix the top plate 1 to the preset installation position on the roof of the factory building using bolts and other fasteners (install the device above the paint recycling tank), ensuring that the top plate 1 is level and stable; S2: Heat tracing pipe length adaptation adjustment S2.1: Loosen the nut on the screw 312 in the length adjustment assembly 3, move the fixing plate 310 upward, and drive the protrusion 311 to slide upward along the guide rail B307, so that the protrusion 311 disengages from the groove 3041 of the inner rod 304 and disengages from the through groove 3011 of the outer rod 301; S2.2: Based on the actual length of the heat tracing pipe to be sprayed, push the inner rod 304 so that it slides smoothly along the guide rail A302 inside the outer rod 301 through the slider A303, and simultaneously drive the electric three-grip chuck B204 to move, and adjust the distance between the electric three-grip chuck A202 and the electric three-grip chuck B204 to match the length of the heat tracing pipe. S2.3: Move the fixing plate 310 downward so that it slides down along the guide rail B307 via the slider B308, causing the protrusion 311 to pass through the through groove 3011 of the outer rod 301 and insert into the groove 3041 of the inner rod 304 at the corresponding position until the fixing plate 310 is in close contact with the top surface of the outer rod 301. S2.4: Insert the nut into the screw 312 and tighten it. The screw 312 and the nut are threaded together to lock the fixing plate 310, so that the protrusion 311 is firmly engaged in the groove 3041, thus completing the fixing of the outer rod 301 and the inner rod 304, thereby realizing the adjustment of the distance between the two chucks. S3: Heat tracing pipe clamping and spraying operation S3.1: Place both ends of the heat tracing pipe to be sprayed into the clamping areas of the electric three-jaw chuck A202 and the electric three-jaw chuck B204 respectively, and start the clamping function of the two chucks to stably clamp both ends of the heat tracing pipe. S3.2: Simultaneously start the motor A201 of the rotating fixing mechanism 2 and the motor B602 of the reciprocating mechanism 6. Motor A201 drives the electric three-jaw chuck A202 to rotate. Through the cooperation of the rotating rod A2033 and the bearing A2032, the electric three-jaw chuck B204 is driven to rotate synchronously, so that the heat tracing tube rotates at a constant speed. Motor B602 drives the lead screw 603 to rotate through forward and reverse rotation, which drives the rod sleeve 604 and the length adjustment component 3 to perform linear reciprocating motion, thereby driving the heat tracing tube to move back and forth. S3.3: Open valve 406 on infusion pipe 404, start booster pump 403, adjust valve 406 opening to control paint delivery flow rate, so that paint is delivered to electric nozzle 405 through infusion pipe 404, start electric nozzle 405, atomize pressurized paint and spray it precisely onto the surface of heat tracing pipe, and achieve comprehensive and uniform spraying of the outer wall through the coordinated cooperation of the rotation and axial reciprocating movement of heat tracing pipe.

[0029] The present invention provides a spray-type heat tracing pipe anti-corrosion coating application device and its application method, which have the following advantages: The length adjustment component 3, through its sliding adjustment structure and insertion locking structure, can quickly adapt to heat tracing pipes of different lengths without disassembling and reassembling the core components, thus solving the problem that traditional equipment can only adapt to a single length and that switching specifications is cumbersome. The device rotates and reciprocates the heat tracing pipe through the upper mechanism. Combined with the directional spraying of the spraying mechanism 4, the outer wall of the heat tracing pipe can be fully and evenly sprayed, replacing manual brushing, greatly improving coating efficiency, reducing labor intensity, and meeting the needs of large-scale industrial production. The stirring component 7 can effectively prevent pigments, fillers, curing agents and other components in the coating from settling, layering or agglomerating due to long-term standing, ensuring that the coating system always maintains a uniform and stable concentration and viscosity, thereby ensuring the quality of subsequent spraying. Through the cooperation of the components on the stirring assembly 7, the stirring paddle 708 on it can achieve a compound motion of "revolution + rotation". Through this motion, the anti-corrosion coating in the storage tank 401 is continuously stirred in all directions without dead angles, achieving a good stirring effect.
