Description

Technical Field

[0001] The present invention relates to the technical field of container lead lining, and particularly to an automatic lead lining device for pressure vessels. Background Art

[0002] In industries such as chemical engineering, energy, and pharmaceuticals, the external wall lead lining process of pressure vessels is mainly used to enhance their corrosion resistance, high-temperature resistance, and mechanical strength. The traditional external wall lead lining process usually adopts manual or semi-automatic methods, mainly including steps such as lead powder spraying, flame cladding, and cooling and solidification. However, the existing technology has the following problems: the traditional method relies on workers to manually spray lead powder and control the flame heating, resulting in high labor intensity and low production efficiency, and it is difficult to meet the requirements of large-scale production; manual spraying is difficult to ensure the uniform distribution of lead powder on the external wall, and the temperature control is unstable during flame heating, which easily leads to uneven lead layer thickness, local peeling, or insufficient cladding, affecting the anti-corrosion effect; lead powder is prone to diffusion during spraying, endangering the health of workers; if the high-temperature flame and liquid nitrogen cooling links are not operated properly, it may cause burns, frostbite, or thermal stress damage to the container; the traditional equipment lacks an effective lead powder recovery system, and the unattached lead powder scatters, not only polluting the environment but also increasing production costs; most of the existing automated equipment uses fixed workstations or single robotic arms for operation, and the container transfer and rotation control are not precise, resulting in unstable spraying and heating effects. Therefore, there is an urgent need to develop a fully automatic external wall lead lining device that can achieve efficient transfer, precise spraying, uniform heating, and rapid cooling to improve production efficiency, ensure the lead lining quality, and reduce safety risks. Summary of the Invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: an automatic lead lining device for pressure vessels, including a main body mechanism for driving the pressure vessel to flow through each station, the main body mechanism including a housing, and a loading and unloading mechanism for placing and removing the pressure vessel and a processing mechanism for lead lining the pressure vessel are arranged on the main body mechanism; The main body mechanism includes a rotating column and a transmission column rotatably installed in the housing, and a fixed rack is fixedly installed in the housing.

[0004] Further, the main body mechanism further includes two conveying wheels rotatably installed in the housing, a conveyor belt is wound around the two conveying wheels, the conveyor belt slides on the housing, a motor is fixedly installed in the housing, a rotating gear and a uniform gear are rotatably installed on the housing, the motor drives the rotating column and the transmission column to rotate through belt transmission, the rotating column drives the uniform gear to rotate through belt transmission, the rotating column drives the conveying wheels to rotate through gear transmission, and the motor drives the rotating gear to rotate through belt transmission and gear transmission.

[0005] Further, a plurality of hoisting modules are fixedly installed below the conveyor belt. The hoisting module includes a connecting seat fixedly installed below the conveyor belt. A plurality of upper wheels and two side wheels are rotatably installed on the connecting seat. The upper wheels and the side wheels roll along the outer shell. A self-rotating gear is rotatably installed below the connecting seat, and three ceramic hooks are rotatably installed below the self-rotating gear.

[0006] Further, an iron core is arranged inside the ceramic hook.

[0007] The motor drives the rotating column and the transmission column to rotate through belt transmission. The rotating column drives the uniform gear to rotate through belt transmission. The motor drives the rotating gear to rotate through belt transmission and gear transmission. The rotating column drives the conveyor wheel to rotate slowly through gear transmission, thereby driving the conveyor belt to move slowly, and thus driving the hoisting module to move slowly. The upper wheels and the side wheels are used to reduce the friction when the hoisting module moves.

[0008] Further, the picking and placing mechanism includes an inlet and outlet slope block fixedly installed on the outer shell. A lower pressing plate is slidably installed on the inlet and outlet slope block. A lower pressing spring is arranged between the lower pressing plate and the inlet and outlet slope block. Two electromagnets are arranged inside the outer shell. A lifting plate is slidably installed on the outer shell.

[0009] Further, a docking cylinder is fixedly installed inside the outer shell. A docking head is rotatably installed at the output end of the docking cylinder. The docking head is slidably installed with the bottom of the rotating column. An insertion head is rotatably installed inside the outer shell. When the docking cylinder extends, the insertion head is inserted into the docking head, so that the rotating column drives the insertion head to rotate.

[0010] Further, a slide rail is fixedly installed inside the outer shell. A rack block is slidably installed on the slide rail. A docking gear is rotatably installed on the slide rail. The docking gear meshes with the rack block. A bottom rotating rod is rotatably installed on the rack block. The bottom rotating rod is rotatably installed with the lifting plate. The insertion head drives the docking gear to rotate through gear transmission and belt transmission.

[0011] When performing the loading operation, the operator or forklift reaches the lower pressing plate, places the pressure vessel on the lifting plate, drives the lower pressing plate to move downward, and the compression spring is compressed. At this time, the docking electric cylinder is controlled to extend, driving the docking head to descend, so that the insertion head is inserted into the docking head. At this time, the rotating column rotates to drive the insertion head to rotate, and the docking gear is driven to rotate through gear transmission and belt transmission, thereby driving the rack block to slide along the slide rail, and then driving the lifting plate to rise through the bottom rotating rod, thereby driving the pressure vessel on the lifting plate to rise. After the hanging ring of the lifting plate contacts the ceramic hook, it pushes the ceramic hook to rotate outward. When the hanging ring of the pressure vessel completely pushes out the ceramic hook, the ceramic hook rotates back under the action of gravity, and the ceramic hook hooks the pressure vessel through the hanging ring. The docking electric cylinder is controlled to contract, so that the docking head is separated from the insertion head. The lifting plate descends and resets under the action of gravity. Subsequently, the personnel leave the lower pressing plate, and the compression spring rebounds to drive the lower pressing plate to reset. Since the moving speed of the compression spring is much slower than the rotating speed of the docking gear, the pressure vessel has enough time to be lifted by the ceramic hook.

[0012] When performing the unloading operation, the operator or forklift reaches the lower pressing plate, and the lower pressing plate moves downward, and the compression spring is compressed. At this time, the docking electric cylinder is controlled to extend, driving the lifting plate to rise. The lifting plate jacks up the pressure vessel on the ceramic hook. At this time, the electromagnet is energized to adsorb the ceramic hook. Subsequently, the docking electric cylinder is controlled to contract, so that the docking head is separated from the insertion head. The lifting plate drives the pressure vessel to descend and reset together under the action of gravity. Subsequently, the personnel leave the lower pressing plate with the pressure vessel, and the compression spring rebounds to drive the lower pressing plate to reset.

[0013] Furthermore, the processing mechanism includes a lead spraying pipe fixedly installed on the housing. A plurality of nozzles are arranged on the lead spraying pipe, and the nozzles are arranged at equal intervals along the inclined lead spraying pipe. A collection box is fixedly installed on the housing, and the collection box is located below the lead spraying pipe. A plurality of fans are arranged on the collection box, and a collection cover plate is rotatably installed on the collection box.

[0014] Furthermore, a heating pipe is fixedly installed inside the housing, a bidirectional lead screw is rotatably installed inside the housing, a lifting seat is slidably installed inside the housing, a flame gun is fixedly installed on the lifting seat, the lifting seat forms a screw drive with the bidirectional lead screw, and the drive column drives the bidirectional lead screw to rotate through belt transmission. A liquid nitrogen pipe is fixedly installed on the housing.

[0015] After the pressure vessel is lifted by the lifting module, first the conveyor belt drives the lifting module to move to the side of the lead spraying pipe. At this time, the self-rotating gear starts to engage with the fixed rack. When the connecting seat moves along with the conveyor belt, the self-rotating gear and the ceramic hook drive the pressure vessel to rotate together. The lead powder is supplied by the lead spraying pipe and ejected through the nozzles on the lead spraying pipe, so that the lead powder adheres to the pressure vessel. The fan on the collection box sucks air, and the unadhered and fallen lead powder is recycled into the collection box. Subsequently, the pressure vessel passes through the heating pipe, the flame gun and the liquid nitrogen pipe in turn. The heating pipe preheats the pressure vessel, which is convenient for subsequent flame heating and can reduce the insufficient melting of the lead powder caused by the temperature difference inside and outside the pressure vessel, ensuring the lead lining effect of the pressure vessel. The transmission column rotates to drive the bidirectional screw to rotate, thereby driving the lifting seat and the flame gun to continuously lift and lower. The high-temperature flame is ejected through the flame gun to heat the pressure vessel by combustion, so that the lead powder quickly melts and adheres to the pressure vessel. Subsequently, the pressure vessel moves to the liquid nitrogen pipe, and liquid nitrogen is ejected through the liquid nitrogen pipe to quickly cool the pressure vessel, completing the lead lining of the pressure vessel.

[0016] The beneficial effects of the present invention compared with the prior art are as follows: (1) The present invention adopts a conveyor belt to cooperate with multi-station collaborative operation to realize the automatic feeding, transfer, spraying, heating and cooling of the pressure vessel, greatly reducing manual intervention. The motor drives the conveyor belt to run at a constant speed, enabling seamless connection of the containers between each station, significantly improving the lead lining efficiency, and being suitable for batch production requirements; (2) The present invention uses the meshing transmission of the self-rotating gear and the fixed rack to drive the pressure vessel to rotate uniformly by the lifting module. Combined with the nozzles of the inclined lead spraying pipe, uniform spraying of the lead powder is realized. The flame gun is driven to lift and lower by a bidirectional screw to ensure uniform heating temperature distribution. Combined with rapid liquid nitrogen cooling, the lead layer is dense and has strong adhesion, avoiding the problems of uneven thickness or insufficient cladding in the traditional process; (3) The collection box and the fan are arranged below the lead spraying pipe of the present invention, which can efficiently recycle the unadhered lead powder and recycle it, reducing material loss. At the same time, the accurately controlled spraying and heating system reduces the overuse of lead powder, further optimizing the production cost and meeting the requirements of green manufacturing.

[0028] The following further describes the detailed implementation manners of the present invention with reference to the accompanying drawings.

[0029] Example: Refer to Figures 1 - 10 , an automatic lead - lining device for a pressure vessel, including a main body mechanism for driving the pressure vessel 4 to flow through each working station. The main body mechanism includes an outer shell 101, and a picking and placing mechanism for putting the pressure vessel 4 in and taking it out and a processing mechanism for lead - lining the pressure vessel 4 are provided on the main body mechanism; The main body mechanism includes a rotating column 105 and a transmission column 114 rotatably installed in the outer shell 101, and a fixed rack 107 is fixedly installed in the outer shell 101.

[0030] As Figures 3 - 6As shown, the main body mechanism further includes two conveyor wheels 102 rotatably installed in the housing 101. A conveyor belt 103 is wound around the two conveyor wheels 102. The conveyor belt 103 slides on the housing 101. A motor 104 is fixedly installed in the housing 101. A rotating gear 106 and a uniform gear 113 are rotatably installed on the housing 101. The motor 104 drives the rotating column 105 and the transmission column 114 to rotate through belt drive. The rotating column 105 drives the uniform gear 113 to rotate through belt drive. The rotating column 105 drives the conveyor wheel 102 to rotate through gear drive. The motor 104 drives the rotating gear 106 to rotate through belt drive and gear drive.

[0031] As Figures 3 - 6 shown, a plurality of lifting modules are fixedly installed below the conveyor belt 103. The lifting module includes a connecting seat 108 fixedly installed below the conveyor belt 103. A plurality of upper wheels 109 and two side wheels 110 are rotatably installed on the connecting seat 108. The upper wheels 109 and the side wheels 110 roll along the housing 101. A self-rotating gear 111 is rotatably installed below the connecting seat 108. Three ceramic hooks 112 are rotatably installed below the self-rotating gear 111.

[0032] As Figures 3 - 6 shown, an iron core is arranged inside the ceramic hook 112.

[0033] The motor 104 drives the rotating column 105 and the transmission column 114 to rotate through belt drive. The rotating column 105 drives the uniform gear 113 to rotate through belt drive. The motor 104 drives the rotating gear 106 to rotate through belt drive and gear drive. The rotating column 105 drives the conveyor wheel 102 to rotate slowly through gear drive, thereby driving the conveyor belt 103 to move slowly, and thus driving the lifting module to move slowly. The upper wheels 109 and the side wheels 110 are used to reduce the friction when the lifting module moves.

[0034] As Figure 7 、 Figure 8 shown, the picking and placing mechanism includes an access slope block 201 fixedly installed on the housing 101. A lower pressing plate 202 is slidably installed on the access slope block 201. A lower pressing spring 203 is arranged between the lower pressing plate 202 and the access slope block 201. Two electromagnets 208 are arranged inside the housing 101. A lifting plate 204 is slidably installed on the housing 101.

[0035] As Figure 7 、 Figure 8 shown, a docking cylinder 205 is fixedly installed inside the housing 101. A docking head 206 is rotatably installed at the output end of the docking cylinder 205. The docking head 206 is slidably installed at the bottom of the rotating column 105. An insertion head 207 is rotatably installed inside the housing 101. When the docking cylinder 205 extends, the insertion head 207 is inserted into the docking head 206, so that the rotating column 105 drives the insertion head 207 to rotate.

[0036] As Figure 7 , Figure 8 shown, a slide rail 210 is fixedly installed inside the outer shell 101. A rack block 209 is slidably installed on the slide rail 210. A docking gear 211 is rotatably installed on the slide rail 210. The docking gear 211 meshes with the rack block 209. A bottom rotating rod 212 is rotatably installed on the rack block 209. The bottom rotating rod 212 is rotatably installed with a lifting plate 204. The insertion head 207 drives the docking gear 211 to rotate through gear transmission and belt transmission.

[0037] When performing the feeding operation, an operator or a forklift arrives on the lower pressing plate 202, places the pressure vessel 4 on the lifting plate 204, drives the lower pressing plate 202 to move downward, and the compression spring 203 is compressed. At this time, the docking electric cylinder 205 is controlled to extend, driving the docking head 206 to descend, so that the insertion head 207 is inserted into the docking head 206. At this time, the rotating column 105 rotates to drive the insertion head 207 to rotate, and through gear transmission and belt transmission, the docking gear 211 is driven to rotate, thereby driving the rack block 209 to slide along the slide rail 210, and thus driving the lifting plate 204 to rise through the bottom rotating rod 212, thereby driving the pressure vessel 4 on the lifting plate 204 to rise. After the hanging ring of the lifting plate 204 contacts the ceramic hook 112, the ceramic hook 112 is pushed to rotate outward. When the hanging ring of the pressure vessel 4 completely pushes out the ceramic hook 112, the ceramic hook 112 rotates back under the action of gravity, and the ceramic hook 112 hooks the pressure vessel 4 through the hanging ring. The docking electric cylinder 205 is controlled to contract, so that the docking head 206 is separated from the insertion head 207. The lifting plate 204 descends and resets under the action of gravity. Subsequently, the personnel leave the lower pressing plate 202, and the compression spring 203 rebounds to drive the lower pressing plate 202 to reset. Since the moving speed of the compression spring 203 is much smaller than the rotating speed of the docking gear 211, the pressure vessel 4 has enough time to be lifted by the ceramic hook 112.

[0038] When performing the discharging operation, an operator or a forklift arrives on the lower pressing plate 202, the lower pressing plate 202 moves downward, and the compression spring 203 is compressed. At this time, the docking electric cylinder 205 is controlled to extend, driving the lifting plate 204 to rise. The lifting plate 204 jacks up the pressure vessel 4 on the ceramic hook 112. At this time, the electromagnet 208 is energized to adsorb the ceramic hook 112. Subsequently, the docking electric cylinder 205 is controlled to contract, so that the docking head 206 is separated from the insertion head 207. The lifting plate 204 drives the pressure vessel 4 to descend and reset together under the action of gravity. Subsequently, the personnel leave the lower pressing plate 202 with the pressure vessel 4, and the compression spring 203 rebounds to drive the lower pressing plate 202 to reset.

[0039] As Figure 9 , Figure 10As shown in the figure, the processing mechanism includes a lead spraying pipe 306 fixedly installed on the outer shell 101. A plurality of nozzles are provided on the lead spraying pipe 306, and the nozzles are arranged at equal intervals along the inclined lead spraying pipe 306. A collection box 307 is fixedly installed on the outer shell 101. The collection box 307 is located below the lead spraying pipe 306. A plurality of fans are provided on the collection box 307, and a collection cover plate 308 is rotatably installed on the collection box 307.

[0040] As Figure 9 , Figure 10 shown in the figure, a heating pipe 304 is fixedly installed inside the outer shell 101. A bidirectional lead screw 301 is rotatably installed inside the outer shell 101. A lifting seat 302 is slidably installed inside the outer shell 101. A flame gun 303 is fixedly installed on the lifting seat 302. The lifting seat 302 forms a threaded drive with the bidirectional lead screw 301. The drive column 114 drives the bidirectional lead screw 301 to rotate through belt drive. A liquid nitrogen pipe 305 is fixedly installed on the outer shell 101.

[0041] After the pressure vessel 4 is lifted by the lifting module, first, the conveyor belt 103 drives the lifting module to move to the side of the lead spraying pipe 306. At this time, the self-rotating gear 111 starts to engage with the fixed rack 107. When the connecting seat 108 moves along with the conveyor belt 103, the self-rotating gear 111 and the ceramic hook 112 drive the pressure vessel 4 to rotate together. The lead powder is supplied by the lead spraying pipe 306 and sprayed out through the nozzles on the lead spraying pipe 306, so that the lead powder adheres to the pressure vessel 4. The fans on the collection box 307 draw air, and the lead powder that does not adhere and falls is recovered into the collection box 307. Subsequently, the pressure vessel 4 passes through the heating pipe 304, the flame gun 303, and the liquid nitrogen pipe 305 in sequence. The heating pipe 304 preheats the pressure vessel 4, which is convenient for subsequent flame heating and can reduce the insufficient melting of the lead powder caused by the temperature difference between the inside and outside of the pressure vessel 4, ensuring the lead lining effect of the pressure vessel 4. The drive column 114 rotates to drive the bidirectional lead screw 301 to rotate, thereby driving the lifting seat 302 and the flame gun 303 to continuously lift and lower. The high-temperature flame is sprayed out through the flame gun 303 to heat the pressure vessel 4 by combustion, so that the lead powder quickly melts and adheres to the pressure vessel 4. Subsequently, the pressure vessel 4 moves to the liquid nitrogen pipe 305, and liquid nitrogen is sprayed out through the liquid nitrogen pipe 305 to quickly cool the pressure vessel 4, completing the lead lining of the pressure vessel 4.

[0042] The working principle of an automatic lead-tinning device for a pressure vessel disclosed by the present invention is as follows: The motor 104 drives the rotating column 105 and the transmission column 114 to rotate through belt drive. The rotating column 105 drives the uniform gear 113 to rotate through belt drive. The motor 104 drives the rotating gear 106 to rotate through belt drive and gear drive. The rotating column 105 drives the conveying wheel 102 to rotate slowly through gear drive, thereby driving the conveyor belt 103 to move slowly, and then driving the hoisting module to move slowly. The upper wheel 109 and the side wheel 110 are used to reduce the friction when the hoisting module moves. When performing the feeding operation, the operator or the forklift arrives on the lower pressing plate 202, places the pressure vessel 4 on the rising plate 204, drives the lower pressing plate 202 to move downward, and the lower pressing spring 203 is compressed. At this time, the docking electric cylinder 205 is controlled to extend, driving the docking head 206 to descend, so that the insertion head 207 is inserted into the docking head 206. At this time, the rotating column 105 rotates to drive the insertion head 207 to rotate, drives the docking gear 211 to rotate through gear drive and belt drive, thereby driving the rack block 209 to slide along the slide rail 210, and then driving the rising plate 204 to rise through the bottom rotating rod 212, so as to drive the pressure vessel 4 on the rising plate 204 to rise. After the hanging ring of the rising plate 204 contacts the ceramic hook 112, it pushes the ceramic hook 112 to rotate outward. When the hanging ring of the pressure vessel 4 completely pushes out the ceramic hook 112, the ceramic hook 112 rotates back under the action of gravity, and the ceramic hook 112 hooks the pressure vessel 4 through the hanging ring. The docking electric cylinder 205 is controlled to contract, so that the docking head 206 is separated from the insertion head 207, and the rising plate 204 descends and resets under the action of gravity. Subsequently, the personnel leave the lower pressing plate 202, and the lower pressing spring 203 rebounds to drive the lower pressing plate 202 to reset. Since the moving speed of the lower pressing spring 203 is much slower than the rotating speed of the docking gear 211, the pressure vessel 4 has enough time to be lifted by the ceramic hook 112.After the pressure vessel 4 is lifted by the lifting module, first the conveyor belt 103 drives the lifting module to move to the side of the lead spraying pipe 306. At this time, the self-rotating gear 111 starts to mesh with the fixed rack 107. When the connecting seat 108 moves along with the conveyor belt 103, the self-rotating gear 111 and the ceramic hook 112 drive the pressure vessel 4 to rotate together. The lead powder is supplied by the lead spraying pipe 306 and ejected through the nozzles on the lead spraying pipe 306, so that the lead powder adheres to the pressure vessel 4. The fan on the collection box 307 sucks air to recover the lead powder that has not adhered and has fallen into the collection box 307. Subsequently, the pressure vessel 4 passes through the heating pipe 304, the flame gun 303 and the liquid nitrogen pipe 305 in sequence. The heating pipe 304 preheats the pressure vessel 4, which is convenient for subsequent flame heating and can reduce the insufficient melting of the lead powder caused by the temperature difference between the inside and outside of the pressure vessel 4, ensuring the lead lining effect of the pressure vessel 4. The transmission column 114 rotates to drive the bidirectional lead screw 301 to rotate, thereby driving the lifting seat 302 and the flame gun 303 to continuously lift and lower. The high-temperature flame is ejected through the flame gun 303 to burn and heat the pressure vessel 4, so that the lead powder quickly melts and adheres to the pressure vessel 4. Subsequently, the pressure vessel 4 moves to the liquid nitrogen pipe 305, and liquid nitrogen is ejected through the liquid nitrogen pipe 305 to quickly cool the pressure vessel 4, completing the lead lining of the pressure vessel 4. When performing the blanking operation, the operator or the forklift arrives on the lower pressing plate 202. The lower pressing plate 202 moves downward, and the lower pressing spring 203 is compressed. At this time, the docking electric cylinder 205 is controlled to extend, driving the lifting plate 204 to rise. The lifting plate 204 jacks up the pressure vessel 4 on the ceramic hook 112. At this time, the electromagnet 208 is energized to adsorb the ceramic hook 112. Subsequently, the docking electric cylinder 205 is controlled to contract, so that the docking head 206 is separated from the insertion head 207. The lifting plate 204 and the pressure vessel 4 descend and reset under the action of gravity. Subsequently, the operator takes the pressure vessel 4 away from the lower pressing plate 202, and the lower pressing spring 203 rebounds to drive the lower pressing plate 202 to reset.

[0043] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
