[0002] The porcelain reactor is an excellent corrosion-resistant equipment. It is made by lining the inner surface of a steel container with high-silicon dioxide glass, and then firmly adhering to the metal surface through high-temperature calcination to form a composite material product. It has the stability of glass and the strength of metal, and is widely used in chemical, petroleum, medicine, pesticide, food and other fields. The existing enamel reactor needs to be sprayed with enamel paint on the reactor during the processing, and then sintered. In the process of spraying the reactor, the reactor is generally placed on its side on two sets of rollers, and then the reactor is driven to rotate by the rollers, and then sprayed by a spraying device.

[0013] Preferably, a surface spraying method for an enamel reactor comprises the following steps:

[0014] S1. In actual use, people first place the reactor body inside the frame, and support the reactor body through the turntable on the bottom frame. During the placement process, the cylinder on the lifting frame pushes the clamping roller toward the reactor body, and the clamping rollers on both sides clamp the reactor body in the center, so that the reactor body is positioned and aligned with the upper spray pipe during the process of being stably fixed;

[0015] S2. After positioning and alignment, the mounting plate is lowered by the hydraulic rod, and then the enamel liquid is sprayed out through the hose and the nozzle by the pump body inside the spray pipe, so as to realize the enamel liquid spraying work on the inner wall of the reactor body. During the spraying process, the slide is driven by the electric push rod to slide up and down along the slide rail, and the slide drives each nozzle to deflect up and down, so as to realize the comprehensive spraying of the inner wall of the reactor body. The gear plate and the rotating table are driven to rotate by the stepping motor through the gear 1, and the fixed sleeve and the spray pipe are driven to rotate through the rotating table, so that the nozzle is rotated and sprayed inside the reactor body, so that the inside of the reactor body is completely sprayed;

[0016] S3, the turntable rotates in the opposite direction synchronously, and the friction force of the top contact surface is used to drive the reactor body to rotate synchronously. The reactor body and the nozzle rotate in the opposite direction, so that the spraying speed of the nozzle is significantly improved. The roller makes the reactor body rotate more smoothly. At the same time, the centrifugal force when the reactor body rotates makes the enamel liquid on the inner wall of the reactor body fit more closely with the inner wall of the reactor body, and the enamel liquid on the inner wall of the reactor body is initially shaken and evenly distributed;

[0017] S4. After spraying is completed, the servo motor is started, and the servo motor drives the pressing frame to press down through the threaded rod, and the pressing frame drives the top fixing block to move down along the spraying pipe. When the top fixing block moves down, the scissor rod drives the connecting plate and the fixing frame to expand to both sides. Through the expansion of the fixing frame and the overall downward pressure during spraying, the smoothing rubber strip on the outside of the fixing frame fits with the inside of the reactor body. At this time, the overall rotation of the fixed sleeve and the spraying pipe drives the smoothing rubber strip to rotate and smooth the inner wall of the reactor body;

[0018] S5. The hub motor inside the fixed groove drives gear 2 to rotate, and the gear 2 drives the spreading rubber strip to rotate by means of the rack, so that the spreading rubber strip can self-circulate at all times during the process of rotating and spreading. During the self-circulation process, the enamel liquid attached to the surface of the spreading rubber strip is scraped off by the wall of the fixed frame and the internal scraper, and then the enamel liquid is recovered through the pump body, the fixed frame and the output pipe.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In actual use, people can first place the reactor body inside the frame, and support the reactor body through the turntable on the base frame. During the placement process, the cylinder on the lifting frame can push the clamping roller toward the reactor body, and the clamping rollers on both sides can clamp the reactor body in the center, so that the reactor body can be positioned and aligned with the upper spray pipe during the process of being stably fixed, which is beneficial to the subsequent enamel liquid spraying work.

[0021] The mounting plate can be lowered by the hydraulic rod, and then the enamel liquid can be sprayed out through the hose and the nozzle by the pump body inside the spray pipe, so as to realize the enamel liquid spraying work on the inner wall of the reactor body. During the spraying process, the electric push rod can drive the slide to slide up and down along the slide rail, and the slide can drive each nozzle to deflect up and down, so as to realize the comprehensive spraying of the inner wall of the reactor body, which is beneficial to practical use. At the same time, the stepper motor can use gear 1 to drive the gear plate and the rotating table to rotate, and the rotating table can drive the fixed sleeve and the spray pipe to rotate, so that the nozzle can rotate and spray inside the reactor body, so that the inside of the reactor body can be completely sprayed.

[0022] During spraying, the turntable will start to rotate in the opposite direction synchronously, and the friction force of the top contact surface of the turntable can be used to drive the reactor body to rotate synchronously. The reverse rotation of the two can significantly improve the spraying speed of the nozzle, and the clamping roller can make the reactor body rotate more smoothly. At the same time, the centrifugal force during the rotation of the reactor body can make the enamel liquid on the inner wall of the reactor body fit more closely to the inner wall of the reactor body, and at the same time, the enamel liquid on the inner wall of the reactor body can be initially shaken and evenly mixed, which is convenient for subsequent correction work. Under the action of centrifugal force, the enamel liquid on the inner wall of the reactor body can offset the effect of gravity, avoiding the enamel liquid from continuing to flow down during spraying, and the enamel liquid accumulates at the bottom of the reactor body, resulting in uneven thickness of the finished enamel layer, which affects the use, and is beneficial to improving the quality of the finished product of the reactor body.

[0023] After spraying is completed, people can start the servo motor, and the servo motor can drive the pressure frame to press down through the threaded rod, and the pressure frame will drive the top fixed block to move downward along the spray pipe. When the top fixed block moves downward, the scissor rod will drive the connecting plate and the fixed frame to expand to both sides, through the expansion of the fixed frame and the overall downward pressure during spraying, because the leveling rubber strip and the inner support strip are made of soft materials, the leveling rubber strip on the outside of the fixed frame can fit with the inside of the reactor body, so that the leveling rubber strip and the inner support strip can achieve self-adaptation to the internal shape of the reactor body, which is beneficial to practical use.

[0024] Through the overall rotation of the fixed sleeve and the spray tube, the smoothing rubber strip can be driven to rotate and smooth the inner wall of the reactor body, and cooperate with the reverse rotation of the reactor body, so that the enamel layer inside the reactor body can be quickly smoothed, which greatly improves the work efficiency and the quality of the finished product. The work of the hub motor inside the fixed groove can drive gear two to rotate, and the gear two can use the rack to drive the smoothing rubber strip to rotate, so that the smoothing rubber strip can always self-circulate during the process of rotating and smoothing, thereby effectively avoiding the accumulation of enamel liquid scraped off the smoothing rubber strip and affecting the subsequent smoothing effect. In the process of self-circulation, the enamel liquid attached to the surface of the smoothing rubber strip can be scraped off by the fixed frame wall and the internal scraper, and then the enamel liquid can be recovered through the pump body, the fixed frame and the output pipe, thereby effectively reducing waste.

A threaded rod 133 runs through the middle of the press frame 134, and the threaded rod 133 is threadedly connected to the press frame 134. The threaded rod 133 is fixedly connected to the bottom driving end of the servo motor 111, and the bottom of the press frame 134 is fixedly connected to the top of the top fixed block 124.

[0042] Furthermore, in a specific implementation, the turntable 105 will start to rotate in the opposite direction synchronously, and the friction force of the top contact surface of the turntable 105 can be used to drive the reactor body 106 to rotate synchronously. The reverse rotation of the two can significantly improve the spraying speed of the nozzle 129, and the clamping roller 109 can make the reactor body 106 rotate more smoothly.

[0049] Among them, a surface spraying method of an enamel reactor includes the following steps:

[0050] S1. In actual use, people first place the reactor body 106 inside the frame 101, and support the reactor body 106 through the turntable 105 on the bottom frame 104. During the placement process, the cylinder 108 on the lifting frame 107 pushes the clamping roller 109 toward the reactor body 106, and the clamping rollers 109 on both sides clamp the reactor body 106 in the center, so that the reactor body 106 is positioned and aligned with the upper spray pipe 132 during the process of being stably fixed;

[0051] S2. After positioning and alignment, the mounting plate 103 is lowered by the hydraulic rod 110, and then the enamel liquid is sprayed out through the hose 137 and the nozzle 129 by the pump body inside the spray tube 132, so as to realize the enamel liquid spraying work on the inner wall of the reactor body 106. During the spraying process, the electric push rod 135 drives the slide 128 to slide up and down along the slide rail 136, and the slide 128 drives each nozzle 129 to deflect up and down, so as to realize the comprehensive spraying of the inner wall of the reactor body 106.

[0052] S3, the turntable 105 rotates in the opposite direction synchronously, and the friction force of the top contact surface is used to drive the reactor body 106 to rotate synchronously. The reactor body 106 and the nozzle 129 rotate in the opposite direction, so that the spraying speed of the nozzle 129 is significantly improved. The roller 109 makes the reactor body 106 rotate more smoothly. At the same time, the centrifugal force when the reactor body 106 rotates makes the enamel liquid on the inner wall of the reactor body 106 fit more closely with the inner wall of the reactor body 106, and at the same time, the enamel liquid on the inner wall of the reactor body 106 is initially shaken and evenly distributed;

[0053] S4. After spraying is completed, the servo motor 111 is started, and the servo motor 111 drives the pressing frame 134 to press down through the threaded rod 133, and the pressing frame 134 drives the top fixing block 124 to move downward along the spraying tube 132. When the top fixing block 124 moves downward, the scissor rod 118 drives the connecting plate 115 and the fixing frame 116 to expand to both sides, and the expansion of the fixing frame 116 and the overall downward pressure during spraying make the smoothing rubber strip 121 on the outside of the fixing frame 116 fit with the inside of the reactor body 106. At this time, the overall rotation of the fixing sleeve 114 and the spraying tube 132 drives the smoothing rubber strip 121 to rotate and smooth the inner wall of the reactor body 106;

[0054] S5. The hub motor 142 inside the fixed groove 143 drives the gear 2 141 to rotate, and the gear 2 141 uses the rack 140 to drive the smoothing rubber strip 121 to rotate, so that the smoothing rubber strip 121 is always in self-circulation during the process of rotating and smoothing. During the self-circulation process, the enamel liquid attached to the surface of the smoothing rubber strip 121 is scraped off through the wall of the fixed frame 116 and the internal scraper 139, and then the enamel liquid is recovered through the pump body, the fixed frame 116 and the output pipe 123.

[0055] Working principle:

[0056] In actual use, people can first place the reactor body 106 inside the frame 101, and the turntable 105 on the bottom frame 104 can support the reactor body 106. During the placement process, the cylinder 108 on the lifting frame 107 can push the clamping roller 109 toward the reactor body 106, and the clamping rollers 109 on both sides can clamp the reactor body 106 in the center, so that the reactor body 106 can be positioned and aligned with the upper spray pipe 132 during the process of being stably fixed, which is beneficial to the subsequent enamel liquid spraying work. After that, the mounting plate 103 can be lowered by the hydraulic rod 110, and then the enamel liquid can be pumped to the nozzle 1 through the hose 137 through the pump body inside the spray pipe 132. 29 is sprayed out, thereby realizing the enamel liquid spraying work on the inner wall of the reactor body 106. During the spraying process, the electric push rod 135 can drive the slide 128 to slide up and down along the slide rail 136, and the slide 128 can drive each nozzle 129 to deflect up and down, so that the inner wall of the reactor body 106 can be fully sprayed, which is beneficial to practical use. At the same time, the stepping motor 113 can use the gear 122 to drive the toothed disc 112 and the rotating table 131 to rotate, and the rotating table 131 can drive the fixed sleeve 114 and the spraying tube 132 to rotate, so that the nozzle 129 can be rotated and sprayed inside the reactor body 106, so that the inside of the reactor body 106 can be completely sprayed. At the same time, the turntable 105 will start to rotate in the opposite direction synchronously, and the friction force of the top contact surface of the turntable 105 can be used to drive the reactor body 106 to rotate synchronously. The reverse rotation of the two can significantly improve the spraying speed of the nozzle 129, and the clamping roller 109 can make the reactor body 106 rotate more smoothly. At the same time, the centrifugal force during the rotation of the reactor body 106 can make the enamel liquid on the inner wall of the reactor body 106 fit more closely with the inner wall of the reactor body 106, and at the same time, the enamel liquid on the inner wall of the reactor body 106 can be initially shaken and evenly distributed, which is convenient for subsequent correction work, and under the action of centrifugal force, the enamel liquid on the inner wall of the reactor body 106 can offset the weight. The effect of force can prevent the enamel liquid from continuing to flow down during spraying. The enamel liquid accumulates at the bottom of the reactor body 106, which makes the thickness of the finished enamel layer uneven and affects the use, which is beneficial to improving the quality of the finished product of the reactor body 106. After the spraying is completed, people can start the servo motor 111, and the servo motor 111 can drive the pressing frame 134 to press down through the threaded rod 133, and the pressing frame 134 will drive the top fixing block 124 to move down along the spraying pipe 132. When the top fixing block 124 moves down, the scissor rod 118 will drive the connecting plate 115 and the fixing frame 116 to expand to both sides. Through the expansion of the fixing frame 116 and the overall downward pressure during spraying, since the uniformly applied rubber strip 121 and the inner support strip 120 are made of soft materials,The smoothing rubber strip 121 on the outside of the fixing frame 116 can fit with the inside of the reactor body 106, so that the smoothing rubber strip 121 and the inner support bar 120 can realize the self-adaptation of the internal shape of the reactor body 106, which is beneficial to practical use. At this time, the overall rotation of the fixing sleeve 114 and the spraying tube 132 can drive the smoothing rubber strip 121 to rotate and smooth the inner wall of the reactor body 106, and cooperate with the reverse rotation of the reactor body 106, so that the enamel layer inside the reactor body 106 can be quickly smoothed, which greatly improves the work efficiency and the quality of the finished product. The work can drive the second gear 141 to rotate, and the rack 140 can be used to drive the smoothing rubber strip 121 to rotate through the second gear 141, so that the smoothing rubber strip 121 can be self-circulated at all times during the rotation and smoothing process, thereby effectively preventing the enamel liquid scraped off the smoothing rubber strip 121 from accumulating and affecting the subsequent smoothing effect. During the self-circulation process, the enamel liquid attached to the surface of the smoothing rubber strip 121 can be scraped off through the wall of the fixed frame 116 and the internal scraper 139, and then the enamel liquid can be recovered through the pump body, the fixed frame 116 and the output pipe 123, thereby effectively reducing waste and facilitating practical use.
