Description

Technical Field

[0001] This invention relates to the field of building assembly equipment technology, specifically to a submerged arc welding flux recovery device for prefabricated steel structure buildings. Background Technology

[0002] In submerged arc welding, flux is a critical consumable, and a large amount of flux will spill around the welding area during welding. If it is not recycled, it will not only waste flux resources and increase welding costs, but also pollute the welding environment with the spilled flux and welding fumes and other impurities, affecting the cleanliness of the production site and the health of workers. However, traditional flux recovery devices generally suffer from low recovery efficiency and poor filtration of impurities in the flux, making it difficult to complete flux recovery efficiently and cleanly.

[0003] Publication number CN209318980U describes a submerged arc welding flux recovery device for prefabricated steel structure buildings. This device utilizes a structure including a movable base frame, mounting box, suction mechanism, first mesh plate, air guide box, second mesh plate, third mesh plate, flow guide plate, top cover, and pipes to solve the problem. The suction mechanism generates suction, which, through the cooperation of the various mesh plates and air guide box components, draws the scattered flux into the device, achieving flux recovery and improving the timeliness and convenience of the recovery process.

[0004] However, the aforementioned technical methods lack effective cooling and cleaning measures for components such as flux tanks and dust collection tanks during the recycling process. During welding, flux tanks and dust collection tanks are prone to overheating due to welding heat radiation and other factors, and dust easily adheres to their exteriors. This can not only affect the stability and quality of flux recycling but also hinder the long-term maintenance of the equipment, which falls short of the requirement for cooling and cleaning flux tanks and dust collection tanks.

[0005] Therefore, in order to address the existing shortcomings, we conducted research and improvements and proposed a submerged arc welding flux recovery device for prefabricated steel structure buildings. Summary of the Invention

[0006] The purpose of this invention is to provide a submerged arc welding flux recovery device for prefabricated steel structure buildings, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a submerged arc welding flux recovery device for prefabricated steel structure buildings, comprising: a chassis, a flux tank provided on one side of the top of the chassis, a dust collection tank provided on the other side of the top of the chassis, and a recovery pipe provided on the top of the flux tank; A compressor is located in the middle of the front top of the chassis, and a transmission pipe is located on the back of the compressor. An adapter pipe is located at one end of the transmission pipe. The bottom end of the adapter tube is provided with a lifting mechanism; The adapter tube is provided with capillary branches on both sides, and one end of the capillary branch on one side of the adapter tube extends into the dust collection bin and is provided with a dust pressing mechanism. The dust suppression mechanism is equipped with a sealing mechanism at its top.

[0008] Furthermore, the lifting mechanism consists of a cooling ring, a slip ring, and a corrugated telescopic pipe. A corrugated telescopic pipe is located at the bottom of the adapter pipe, slip rings are symmetrically arranged at the bottom of the corrugated telescopic pipe, and a cooling ring is located at the top of the slip ring. A gas chamber is located inside the slip ring, and a connecting channel is provided at the connection between the cooling ring and the slip ring. This structural design allows the corrugated telescopic pipe to move synchronously with the slip ring and the cooling ring when it is inflated and expanded. Simultaneously, the gas inside the slip ring can enter the cooling ring through the connecting channel, providing power and a medium for the cooling and cleaning functions of the cooling ring, thus ensuring the effective action on the barrel during the lifting process.

[0009] Furthermore, a one-way valve is installed between the transmission pipeline and the adapter pipe, and a one-way valve is installed between the adapter pipe and the capillary branch pipe. The one-way valves can prevent backflow of gas during transmission, ensuring that the compressed gas can flow sequentially from the transmission pipeline to the adapter pipe and the capillary branch pipe according to the preset path, and then accurately deliver it to each mechanism that requires gas action, ensuring that each mechanism can work stably and orderly.

[0010] Furthermore, the dust suppression mechanism comprises a filter screen, a material gathering ring, a guide plate, a protective inner ring, a limiting plate, a slide rod, a protective outer ring, a bottom ring, a material trough, and a spring. The inner side of the dust collector is provided with a protective inner ring, and symmetrical protrusions are arranged on the inner side of the protective inner ring. A slide rod is vertically inserted through the inner side of each protrusion, and a spring is sleeved on the outside of the slide rod. A limiting plate is provided at the top of the slide rod. A protective outer ring is provided outside the protective inner ring, and the inner sides of the protective outer ring and the protective inner ring are... The device includes a material-gathering ring with a material trough on its inner side. A bottom ring is located at the bottom of the protective inner ring, and guide plates are symmetrically arranged on the inner side of the bottom ring. A filter screen is attached to one end of each guide plate. When gas is introduced into the material trough, it moves the protective inner ring and other components along a sliding rod, thereby moving the filter screen within the dust collection bin to filter impurities in the flux. Springs and limiting plates ensure the stability of the protective inner ring's movement and the reliability of its reset, allowing the dust-pressing and filtering process to proceed continuously and effectively.

[0011] Furthermore, the guide plate and the filter screen are fixedly connected, and the bottom ring and the protective inner ring are fixedly connected. The fixed connection ensures the firmness of the connection between the guide plate and the filter screen, and between the bottom ring and the protective inner ring. When the protective inner ring moves the bottom ring, the guide plate can stably move the filter screen, avoiding the filter screen from shifting due to loose connection, which would affect the filtration effect and ensure the stability of the dust suppression mechanism.

[0012] Furthermore, the protective inner ring moves vertically on the outside of the slide bar. The protective inner ring and the bottom ring are integrally welded. The integrally welded structure makes the protective inner ring and the bottom ring form a whole. When the protective inner ring moves vertically along the slide bar, the bottom ring can move synchronously and stably, thereby ensuring the consistency of movement of the guide plate and the filter screen, improving the coordination of movement of various components of the dust pressing mechanism, and facilitating efficient filtration of impurities.

[0013] Furthermore, the polymer ring is nested with the inner and outer protective rings. This nested connection facilitates the installation and disassembly of the polymer ring. At the same time, when the polymer ring is subjected to gas pressure, it can move stably between the inner and outer protective rings, providing a structural basis for the subsequent movement of components such as the inner protective ring. It also facilitates the maintenance and replacement of the polymer ring.

[0014] Furthermore, the material trough is located at the top of the material gathering ring, and the inner side of the material trough is connected to the capillary branch tube. The material trough being located at the top of the material gathering ring and connected to the capillary branch tube allows the compressed gas transported by the capillary branch tube to directly enter the material trough. When the material trough is full of gas, it can quickly generate downward pressure on the material gathering ring, thereby timely driving the movement of components such as the protective inner ring, ensuring the timely response of the dust suppression mechanism and improving the filtration efficiency.

[0015] Furthermore, the sealing mechanism consists of an annular bladder and a diversion pipe. The diversion pipe is transversely arranged through the inner side of the protective inner ring, and the annular bladder is provided at the top of the diversion pipe so that the diversion pipe can smoothly transport the gas in the material trough to the annular bladder. When the annular bladder is inflated, it can form a seal at the connection between the lid and the body of the dust collector. The simple structure achieves a good sealing function, providing a relatively closed environment for the recovery and purification of the flux in the barrel.

[0016] Furthermore, the end of the diversion pipe located inside the inner protective ring is connected to the material trough through it. A pressure valve is provided at the connection between the material trough and the diversion pipe. A one-way valve is provided between the annular bladder and the diversion pipe. An air outlet is provided on one side outside the annular bladder, and a pressure valve is provided between the air outlet and the annular bladder.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The lifting mechanism of the present invention is driven by the expansion of the corrugated telescopic pipe to move the slip ring and the cooling ring. At the same time, the low temperature gas is used to reduce the external temperature of the flux bucket and the dust removal bucket during the movement of the cooling ring, and can also clean the external dust, thereby achieving cooling and cleaning of the bucket body, ensuring that the bucket body is at a suitable working temperature and has a clean appearance. 2. In the dust suppression mechanism of the present invention, the gas introduced by the capillary branch tube causes the material trough to be filled with air and press down the material gathering ring, which drives the protective inner ring, bottom ring, etc. to move, thereby allowing the filter screen to move and filter impurities in the dust removal bucket, effectively purifying the flux in the dust removal bucket and improving the flux recovery quality. 3. In this invention, when the gas pressure inside the material ring is too high, the diversion pipe guides the gas into the annular bladder to make it inflate. This can seal the connection between the dust collector lid and the body of the bucket in a short time, reduce the entry of dust and other impurities, ensure the stability of the environment inside the bucket, and facilitate the recovery and treatment of flux.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example: like Figures 1 to 7 As shown, a submerged arc welding flux recovery device for prefabricated steel structure buildings includes: a chassis 1, a flux tank 3 on one side of the top of the chassis 1, a dust removal tank 5 on the other side of the top of the chassis 1, and a recovery pipe 4 on the top of the flux tank 3. A compressor 2 is located in the middle of the front top of the chassis 1. A transmission pipe 8 is located on the back of the compressor 2. An adapter pipe 22 is located at one end of the transmission pipe 8. A lifting mechanism is provided at the bottom end of the adapter tube 22; Capillary branch pipes 21 are provided on both sides of the adapter pipe 22, and one end of the capillary branch pipe 21 on one side of the adapter pipe 22 extends into the dust collection bucket 5 and is provided with a dust pressing mechanism. A sealing mechanism is provided at the top of the dust suppression mechanism; A one-way valve is installed between the transmission pipe 8 and the adapter pipe 22, and a one-way valve is installed between the adapter pipe 22 and the capillary branch pipe 21. During submerged arc welding, a large amount of flux is scattered around the welding area. The casing 1 uses its pre-set power system, such as a fan, to generate negative pressure and draw the scattered flux into the system. The flux itself is then drawn into the flux tank 3, where it is initially collected and temporarily stored. Subsequently, flux containing impurities, including welding fumes and small particulate waste, is transported to the dust collection tank 5. At the same time, compressor 2 is started. Compressor 2 introduces compressed gas into adapter pipe 22 through transmission pipe 8. Adapter pipe 22 introduces compressed gas into capillary branch pipe 21 on one side of dust collector 5 and flux tank 3. Furthermore, compressor 2 is essentially a device that converts mechanical energy into gas pressure energy. Typically, it is driven by an electric motor and compresses gas through mechanical components such as pistons, screws, and centrifugal impellers. Taking a common piston compressor as an example, when the motor drives the crankshaft to rotate, the crankshaft converts the rotational motion into the reciprocating linear motion of the piston within the cylinder via a connecting rod; During the intake process, the piston moves out of the cylinder, increasing the volume inside the cylinder and reducing the pressure. When the pressure is lower than the pressure at the intake port, the external gas pushes open the intake valve under the action of the pressure difference and enters the cylinder. During the compression process, the piston moves into the cylinder, the cylinder volume gradually decreases, the gas is compressed, and the pressure and temperature rise; when the pressure reaches a certain level, the exhaust valve is pushed open, and the compressed gas is transported to the adapter pipe 22 through the transmission pipe 8.

[0022] Example 1: As Figures 1 to 7 As shown, the lifting mechanism consists of a cold compress ring 6, a slip ring 7, and a corrugated telescopic pipe 9. The bottom end of the adapter pipe 22 is provided with a corrugated telescopic pipe 9, the bottom of the corrugated telescopic pipe 9 is symmetrically provided with a slip ring 7, the top of the slip ring 7 is provided with a cold compress ring 6, the inside of the slip ring 7 is provided with a gas cavity, and a connection channel is provided at the connection between the cold compress ring 6 and the slip ring 7. When the gas introduced by the compressor 2 through the transmission pipe 8 is released into the adapter pipe 22, the adapter pipe 22 introduces the gas into the corrugated expansion pipe 9. After the corrugated expansion pipe 9 is filled with gas, it gradually expands downward. When the corrugated expansion pipe 9 expands, it will drive the slip ring 7 to move downward. When the slip ring 7 moves downward, it will drive the cooling ring 6 to move up and down on the outside of the dust collector 5 and the flux collector 3 respectively. Since the user can control the temperature of the gas introduced by the compressor 2, so that the temperature of the gas is lower, the temperature of the gas inside the corrugated expansion pipe 9 is lower. The corrugated expansion pipe 9 can also introduce the low temperature gas into the slip ring 7, and the slip ring 7 then introduces the low temperature gas into the interior of the cooling ring 6. When the cooling ring 6 and the slip ring 7 move up and down with the expansion of the corrugated expansion pipe 9, the low temperature surface of the cooling ring 6 will continuously reduce the temperature of the outside of the flux collector 3 and the dust collector 5. At the same time, when the inside of the cooling ring 6 passes through the outer shell of the flux collector 3 and the dust collector 5, it will also clean the dust on the outside of the flux collector 3 and the dust collector 5.

[0023] Example 2: Figures 1 to 7 As shown, the dust collection mechanism consists of a filter screen 10, a material gathering ring 11, a guide plate 12, a protective inner ring 13, a limiting plate 14, a sliding rod 15, a protective outer ring 16, a bottom ring 17, a material trough 18, and a spring 23. The inner side of the dust collection bucket 5 is provided with a protective inner ring 13, and the inner side of the protective inner ring 13 is symmetrically provided with protrusions. The inner side of the protrusions is vertically connected with a sliding rod 15, and the outer side of the sliding rod 15 is fitted with a spring 23. The top of the sliding rod 15 is provided with a limiting plate 14. The outer side of the protective inner ring 13 is provided with a protective outer ring 16. The inner side of the protective outer ring 16 and the inner side of the protective inner ring 13 is provided with a material gathering ring 11. The inner side of the material gathering ring 11 is provided with a material trough 18. The bottom of the protective inner ring 13 is provided with a bottom ring 17, and the inner side of the bottom ring 17 is symmetrically provided with guide plates 12. One end of the guide plate 12 is provided with a filter screen 10. The guide plate 12 and the filter screen 10 are fixedly connected, and the bottom ring 17 and the protective inner ring 13 are fixedly connected; The protective inner ring 13 moves vertically outside the slide bar 15, and the protective inner ring 13 and the bottom ring 17 are an integral welded structure. The material-aggregating ring 11 is nested with the inner protective ring 13 and the outer protective ring 16. The material trough 18 is located at the top of the material gathering ring 11, and the inner side of the material trough 18 is connected to the capillary branch tube 21 through the connection. When the capillary branch tube 21 near the dust collector 5 starts to introduce gas, the capillary branch tube 21 introduces the gas into the material trough 18 at the top of the material gathering ring 11 inside the inner protective ring 13 and the outer protective ring 16. When the material trough 18 is filled with gas, the material trough 18 presses down on the material gathering ring 11. When the material gathering ring 11 moves down, it will drive the inner protective ring 13 and the outer protective ring 16 to move synchronously. At this time, when the inner protective ring 13 moves, the protrusion on the inner side of the inner protective ring 13 will move outside the slide rod 15. The limiting piece 14 prevents the inner protective ring 13 from moving too high, and the spring 23 will help the inner protective ring 13 to reset after losing gas pressure. When the inner protective ring 13 moves, it will drive the bottom ring 17 to move synchronously. When the bottom ring 17 moves, the guide plate 12 and the filter screen 10 also move synchronously. When the filter screen 10 moves, it will continuously filter the impurities inside the dust collection bin 5, thereby purifying the flux liquid inside the dust collection bin 5.

[0024] Example 3: Figures 1 to 7 As shown, the sealing mechanism consists of an annular bladder 19 and a diversion tube 20. The diversion tube 20 is transversely arranged inside the inner side of the protective inner ring 13, and the annular bladder 19 is arranged at the top of the diversion tube 20. One end of the diversion pipe 20 located inside the inner protective ring 13 is connected to the material trough 18 through the pipe. A pressure valve is provided at the connection between the material trough 18 and the diversion pipe 20. A one-way valve is provided between the annular bladder 19 and the diversion pipe 20. An air outlet is provided on one side of the annular bladder 19. A pressure valve is provided between the air outlet and the annular bladder 19. When the gas pressure inside the agglomerating ring 11 is too high, the valve between the agglomerating ring 11 and the diversion pipe 20 opens, and the diversion pipe 20 introduces the gas into the annular bladder 19. The annular bladder 19 changes from a deflated state to an inflated state. Since the annular bladder 19 is located at the upper end of the dust collector 5, the inflated annular bladder 19 can seal the connection between the lid and the body of the dust collector 5 for a short time. When the gas pressure inside the annular bladder 19 is too high, gas is ejected from the outlet outside the annular bladder 19.

[0025] Example 4: Figures 1 to 7 As shown, the inner side of the cooling ring 6 of the lifting mechanism can be replaced with a magnetic suction plate, and a temperature control module is added inside the slip ring 7. In the presence of ferromagnetic dust in the welding environment, the cooling ring 6, replaced by a magnetic suction plate, can adsorb ferromagnetic dust from the outside of the flux container 3 and dust collection container 5 as it moves up and down. Combined with the low-temperature cleaning effect, this improves cleaning efficiency. The temperature control module can automatically adjust the temperature of the introduced gas according to the ambient temperature, enhancing the cooling effect in high-temperature environments and reducing cooling in low-temperature environments to prevent condensation from forming on the container due to excessive temperature differences.

[0026] Example 5: Figures 1 to 7 As shown, the filter screen 10 of the dust suppression mechanism can be replaced with different pore sizes, and a wear-resistant coating is added to the surface of the guide plate 12. Specifically, replacing the filter screen 10 with one of corresponding pore sizes can improve the targeting of filtration for flux impurities of different particle sizes. Small-pore filter screens are used for fine impurities, while large-pore filter screens are used for larger waste residues, thereby improving purification accuracy. The wear-resistant coating on the surface of the guide plate 12 reduces wear during long-term movement, extends the service life of the dust pressing mechanism, and ensures the stability of the filter screen 10's movement.

[0027] Example 6: Figures 1 to 7 As shown, the annular bladder 19 of the sealing mechanism is wrapped with a high-temperature resistant silicone layer, and a flow regulating valve is added to the diversion pipe 20. In high-temperature welding environments, a high-temperature resistant silicone layer protects the annular bladder 19 from high-temperature damage, ensuring stable sealing performance. A flow regulating valve controls the amount of gas entering the annular bladder 19, adjusting the expansion level according to the sealing requirements of the dust collector 5 to reduce gas waste and prevent damage to the annular bladder 19 due to excessive expansion, thus improving the adaptability of the sealing mechanism.

[0028] Example 7: Figures 1 to 7 As shown, the cooling ring 6 of the lifting mechanism is made of copper alloy with better thermal conductivity, and several heat-conducting fins are provided on the inner side of the cooling ring 6. The connection channel between the sliding ring 7 and the cooling ring 6 is sealed with heat-conducting silicone. In particular, due to the excellent thermal conductivity of copper alloy, when the low-temperature gas enters the cooling ring 6 through the corrugated expansion pipe 9 and slip ring 7, the copper alloy cooling ring 6 can transfer the low temperature to its surface more quickly. The heat-conducting fins on the inner side further increase the contact area with the outer shell of the flux bucket 3 and the dust removal bucket 5, improving the heat exchange efficiency and making the cooling effect more significant. At the same time, the thermally conductive silicone-sealed connection channel not only ensures the gas sealing, but also enhances the thermal conductivity between the slip ring 7 and the cooling ring 6, allowing the low temperature to be transferred more smoothly from the slip ring 7 to the cooling ring 6.

[0029] Example 8: Figures 1 to 7 As shown, a pressure sensor is installed inside the material gathering ring 11 of the dust pressing mechanism, a displacement sensor is installed on the slide rod 15, and a display module is added to the control panel of the chassis 1. The pressure sensor monitors the gas pressure inside the material-collecting ring 11 in real time, while the displacement sensor detects the displacement of the slide bar 15, thus indirectly reflecting the movement status of the inner protective ring 13 and the filter screen 10. The data collected by these sensors is transmitted to the display module, allowing operators to intuitively understand the operating parameters of the dust-collecting mechanism.
