A toothed plate is slidably connected inside the limiting frame, and a threaded tube is fixedly installed on one side of the toothed plate. The helical teeth are located inside the threaded tube and are threadedly connected to the threaded tube. One side of the toothed plate's teeth is inserted into the grooves at both ends of the socket. A retractable rod is fixedly connected between the toothed plate and the limiting box, and a telescopic spring is sleeved on the outer side of the retractable rod.

[0010] Preferably, the drying assembly includes a blower box fixedly installed inside one end of the processing box, with a bent pipe fixedly installed at the end of the blower box away from the processing box, and a tapered pipe fixedly installed at the bottom of the bent pipe. A heating wire is fixedly connected inside the blower box, and a fixed box is fixedly connected inside the blower box.

[0013] Preferably, the first conical tooth and the second conical tooth are engaged in a meshing connection.

[0014] Preferably, the third conical tooth and the fourth conical tooth are engaged.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The surface treatment equipment for carbon steel pipes is as follows: When the operator starts the paint pump, the anti-corrosion paint inside the paint tank passes through the connecting pipe, conveying pipe, annular groove, and spray pipe into the nozzle. Four sets of nozzles are used to evenly spray the four sides of the carbon steel pipe. The design of the inclined ring plate, which fits snugly against the outside of the carbon steel pipe, scrapes off excess paint from the surface of the carbon steel pipe. This achieves the effect of quickly spraying anti-corrosion paint onto the surface of carbon steel pipes of various specifications. The four sets of nozzles achieve all-round spraying of the carbon steel pipe surface, effectively avoiding uneven spraying. Furthermore, the inclined ring plate scrapes off excess paint from the surface of the carbon steel pipe, effectively reducing... Minimal paint droplet residue improves the adhesion and anti-corrosion effect of the coating, preventing unevenness on the pipe surface after drying. The process involves a worker starting a motor to rotate a drive rod. The rotation of the third conical tooth drives the rotation of the fourth conical tooth, which in turn rotates multiple sets of fan blades. This causes external air to be discharged into the treatment chamber through the air box, bend, and conical pipe. Simultaneously, the heating wire heats the air flowing inside the air box. The hot air circulates within the treatment chamber, drying the anti-corrosion coating on the carbon steel pipe surface. This rapid drying ensures uniform adhesion of the coating to the pipe surface, improving anti-corrosion performance, shortening the production cycle, and increasing production efficiency.

[0016] 1. The coating pump is activated by the operator, allowing the anti-corrosion coating inside the coating tank to pass through the connecting pipe, delivery pipe, annular groove, and spray pipe into the nozzles. Four sets of nozzles are used to evenly spray the four sides of the carbon steel pipe. The operator then slowly moves the carbon steel pipe inside the treatment tank. One end of the carbon steel pipe passes through and slides against the inclined ring plate. The design of the inclined ring plate's inner side fitting snugly against the outer side of the carbon steel pipe scrapes away excess coating. This allows for rapid application of anti-corrosion coating to the surface of carbon steel pipes of various specifications. The four-nozzle design ensures all-around coating of the carbon steel pipe surface, effectively preventing uneven coating and reducing the risk of uneven application. The residue of paint droplets helps improve the adhesion and anti-corrosion effect of the anti-corrosion coating, and avoids unevenness on the surface of the pipeline after subsequent drying. By rotating the rotating rod inside the limit box, the rotation of the rotating rod drives the rotation of the first conical tooth, which in turn drives the rotation of the second conical tooth, which in turn drives the rotation of the transmission rod, which in turn drives the rotation of the helical tooth. Since the helical tooth is connected to the internal thread of the threaded pipe, the rotation of the helical tooth causes the toothed plate to slide inside the limit frame. At this time, the retraction rod and the telescopic spring retract, and multiple sets of teeth on one side of the toothed plate are inserted into the grooves at both ends of the socket, thereby achieving the effect of quickly fixing the limit socket. This makes it easier for the operator to change the appropriate inclined ring plate according to the thickness of the carbon steel pipe, thus greatly improving the flexibility of pipeline spraying.

[0017] 2. The motor is started by the operator, which drives the drive rod to rotate. The rotation of the drive rod drives the third conical tooth to rotate, which in turn drives the fourth conical tooth to rotate. The rotation of the fourth conical tooth drives the rotating rod to rotate, which in turn drives multiple sets of fan blades to rotate. The rotation of the fan blades creates negative pressure inside the air box, which in turn forces outside air to pass through the air box, bend, and conical pipe into the processing chamber. At the same time, the heating wire heats the air flowing inside the air box. The hot air circulates inside the processing chamber and dries the anti-corrosion coating on the carbon steel pipe surface. This achieves a rapid drying effect on the anti-corrosion coating on the carbon steel pipe surface, further ensuring that the coating adheres evenly to the pipe surface, improving the anti-corrosion effect, shortening the production cycle, and increasing production efficiency.

[0027] The spraying mechanism 2 includes an annular plate 201 fixedly installed inside one side of the processing box 101. A paint tank 202 is fixedly installed on the top side of the processing box 101, and a paint pump 203 is fixedly installed on the bottom side of the paint tank 202. A delivery pipe 204 is fixedly connected between the paint pump 203, the processing box 101, and the annular plate 201. A connecting pipe 205 is fixedly connected between the paint pump 203 and the paint tank 202. An annular groove 206 is formed inside the annular plate 201, and spray pipes 207 are symmetrically embedded on the inner side of the annular plate 201. A nozzle 208 is fixedly installed at the end of the spray pipe 207 away from the annular plate 201. An installation groove 209 is formed on the top of the processing box 101. A socket 210 is inserted into the inner side of the device, and a fixing rod 211 is fixedly installed at the bottom of the socket 210. An inclined ring plate 212 is fixedly installed at the bottom of the fixing rod 211, and a support rod 213 is fixedly installed at the bottom of the inclined ring plate 212. This enables the rapid application of anti-corrosion coating to the surface of carbon steel pipes of various specifications. The design of four sets of nozzles 208 enables all-round spraying of the carbon steel pipe surface, effectively avoiding uneven spraying. The inclined ring plate 212 scrapes off excess coating from the carbon steel pipe surface, effectively reducing coating droplet residue, which is beneficial to improving the adhesion and anti-corrosion effect of the anti-corrosion coating and preventing unevenness on the surface of the pipe after subsequent drying.

[0028] The top of the processing box 101 is symmetrically fitted with a limiting box 214, and a limiting frame 215 is fixedly installed on one side of the limiting box 214. A rotating rod 216 is rotatably connected to the upper interior of the limiting box 214, and a transmission rod 217 is rotatably connected between the limiting box 214 and the limiting frame 215. The outer end of the transmission rod 217 near the limiting frame 215 is welded with helical teeth 218. A first conical tooth 219 is fixedly installed at the bottom of the rotating rod 216, and a second conical tooth 220 is fixedly installed on the outside of the transmission rod 217.

Furthermore, one side of the toothed plate 221 is inserted into the grooves at both ends of the socket 210, and a retractable rod 223 is fixedly connected between the toothed plate 221 and the limiting box 214. A telescopic spring 224 is sleeved on the outside of the retractable rod 223, thereby achieving the effect of quickly fixing the limiting socket 210. This makes it easier for workers to change the appropriate inclined ring plate 212 according to the thickness of the carbon steel pipe, which greatly improves the flexibility of pipe spraying and brings convenience to workers during use. Supports 226 are symmetrically fixedly installed at both ends of the treatment box 101, and a transmission roller 227 is rotatably connected to the inner side of the top of the support 226. When the carbon steel pipe moves inside the treatment box 101, the bottom of the carbon steel pipe is located at the top of the transmission roller 227 and rolls, thereby causing the transmission roller 227 to rotate inside the support 226, which makes the movement of the carbon steel pipe more stable.

[0029] The drying assembly 3 includes an air box 301 fixedly installed inside one end of the processing chamber 101. A bent pipe 302 is fixedly installed at the end of the air box 301 away from the processing chamber 101, and a tapered pipe 303 is fixedly installed at the bottom of the bent pipe 302. A heating wire 3031 is fixedly connected inside the air box 301, and a fixed box 304 is fixedly connected inside the air box 301. A drive rod 305 is rotatably connected between the air box 301, the fixed box 304, and the processing chamber 101. A motor 306 is fixedly installed at the top of the drive rod 305. A rotating rod 307 is rotatably connected inside one side of the fixed box 304, and the outside of the rotating rod 307 is fixedly... The fan blade 308 is fixedly installed, and a third conical tooth 309 is fixedly installed on the outer bottom of the drive rod 305. A fourth conical tooth 310 is fixedly installed on one end of the rotating rod 307. The third conical tooth 309 and the fourth conical tooth 310 are meshed together. A filter screen 311 is fixedly installed inside one end of the air box 301. This enables the rapid drying of the anti-corrosion coating on the surface of the carbon steel pipe, further ensuring that the coating is evenly adhered to the pipe surface, improving the anti-corrosion effect, shortening the production cycle, improving production efficiency, and providing convenience for the staff during use. The design of the filter screen 311 prevents large external impurities from entering the treatment box 101.

[0030] Working principle: Before using this carbon steel pipe surface treatment equipment, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, firstly, the worker inserts the socket 210 into the installation slot 209. At this time, the bottom of the support rod 213 contacts the bottom side of the inside of the treatment box 101. Then, the worker inserts the carbon steel pipe into the treatment box 101 through the inlet. At this time, the worker starts the paint pump 203, which allows the anti-corrosion paint inside the paint box 202 to enter the spray nozzle 208 through the connecting pipe 205, the delivery pipe 204, the annular groove 206, and the spray pipe 207. The four sets of spray nozzles 208 are used to evenly spray the four sides of the carbon steel pipe. At this time, the worker slowly moves the carbon steel pipe inside the treatment box 101. At this time, one end of the carbon steel pipe penetrates... The inclined ring plate 212 is slidably connected to the carbon steel pipe. The design of the inner side of the inclined ring plate 212 fitting snugly against the outer side of the carbon steel pipe scrapes away excess coating, enabling rapid application of anti-corrosion coating to various specifications of carbon steel pipes. The design of four spray nozzles 208 ensures all-around spraying of the carbon steel pipe surface, effectively preventing uneven coating. Furthermore, the inclined ring plate 212 scrapes away excess coating, reducing paint droplet residue and improving the adhesion of the anti-corrosion coating. To enhance strength and corrosion resistance, and prevent unevenness on the pipe surface after subsequent drying, the operator rotates the rotating rod 216 inside the limiting box 214. This rotation of the rod 216 drives the first conical tooth 219, which in turn drives the second conical tooth 220. The second conical tooth 220 then drives the transmission rod 217, which in turn drives the helical tooth 218. Since the helical tooth 218 is threaded into the threaded pipe 222, its rotation causes the toothed plate 221 to slide within the limiting frame 215. When the retracting rod 223 and the telescopic spring 224 retract, multiple sets of teeth on one side of the toothed plate 221 are inserted into the grooves at both ends of the socket 210, thereby achieving the effect of quickly fixing the limit socket 210. This makes it easier for workers to replace the appropriate inclined ring plate 212 according to the thickness of the carbon steel pipe, which greatly improves the flexibility of pipe spraying and brings convenience to workers. When the carbon steel pipe moves inside the treatment box 101, the bottom of the carbon steel pipe is located at the top of the transmission roller 227 and rolls, which causes the transmission roller 227 to rotate inside the support 226, thereby making the movement of the carbon steel pipe more stable.

[0031] When the operator starts the motor 306, it drives the drive rod 305 to rotate. The rotation of the drive rod 305 drives the third conical tooth 309 to rotate, which in turn drives the fourth conical tooth 310 to rotate. The rotation of the fourth conical tooth 310 drives the rotating rod 307 to rotate, which in turn drives the multiple sets of fan blades 308 to rotate. The rotation of the fan blades 308 creates a negative pressure inside the air box 301, which in turn forces outside air through the air box 301, the bend pipe 302, and the conical pipe 303 into the processing box 101. At the same time, the operation of heating wire 3031 heats the air flowing inside the air box 301. At this time, the hot air inside the treatment box 101 circulates and dries the anti-corrosion coating on the surface of the carbon steel pipe. This achieves the effect of quickly drying the anti-corrosion coating on the surface of the carbon steel pipe, further ensuring that the coating is evenly adhered to the pipe surface, improving the anti-corrosion effect, shortening the production cycle, improving production efficiency, and bringing convenience to the staff during use. Through the design of filter screen 311, the phenomenon of large external impurities entering the treatment box 101 is avoided.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
