Description

Technical Field

[0001] This application relates to the field of belt conveyor cleaning and protection technology, and in particular to a belt conveyor for welding fume control. Background Technology

[0002] Belt conveyors are a type of equipment that uses a ring-shaped conveyor belt as the traction and load-bearing component, relying on friction to achieve continuous transport of materials or products. In welding workshops, belt conveyors are also needed for continuous transport of workpieces. However, due to the characteristics of welding workshops, such as spattered welding slag and pervasive welding fumes, belt conveyors are easily affected by the spattered welding slag, leading to belt erosion and a shorter service life. Furthermore, welding fumes easily adhere to the belt surface, causing belt misalignment and slippage. Therefore, protective structures are required for belt conveyors installed in welding workshops.

[0003] The main protective measures used in the existing technology are: 1. Using belts made of high-temperature resistant materials, such as silicone or Teflon coated belts. Although this method can extend the service life of the belt, it increases the application cost, and the belt's wear resistance is insufficient, which cannot meet the requirements for carrying and transporting workpieces; 2. Setting up a protective cover on the outside of the belt. Although this method can block the spattered welding slag to a certain extent, it cannot solve the problem of belt deviation and slippage caused by welding fumes. Therefore, neither using belts made of high-temperature resistant materials nor simply setting up a protective cover can solve the problem that belt conveyor lines in welding workshops are easily affected by welding slag and welding fumes, resulting in ablation, deviation, or slippage. Summary of the Invention

[0004] In order to solve the problem that belt conveyors in welding workshops are easily affected by welding slag and welding fumes, resulting in erosion, deviation or slippage, this application provides a welding fume control belt conveyor.

[0005] This application provides a welding fume control belt conveyor line, which adopts the following technical solution: A welding fume control belt conveyor line includes: a belt conveyor assembly, an anti-spatter protection assembly, and a dust collection and protection assembly. The belt conveyor assembly includes a frame and a conveyor belt, with the conveyor belt disposed within the frame. The anti-spatter protection assembly is mounted on the outside of the frame and includes a pair of primary protective plates and a blocking protective plate. The pair of primary protective plates are symmetrically arranged on both sides of the frame, and the blocking protective plate is detachably fixed on the side of the frame corresponding to the welding station, and cooperates with the pair of primary protective plates to form a welding slag blocking and protection unit. The dust collection and protection assembly is configured in conjunction with the assembly frame. The dust collection and protection assembly includes a dust collection and filtration unit, a negative pressure dust collection component, a positive pressure spray plate, and a cleaning unit. The dust collection and filtration unit has two suction ports and two air outlets. The negative pressure dust collection component and the positive pressure spray plate are both fixedly connected to the mounting frame. The negative pressure dust collection component is connected to one suction port of the dust collection and filtration unit, and the positive pressure spray plate is connected to the two air outlets of the dust collection and filtration unit. The negative pressure dust collection component and the positive pressure spray plate cooperate to form a protective wind wall. The cleaning unit is fixedly installed above the dust collection and filtration unit and is configured to cooperate with the frame. The cleaning unit is connected to the other suction port of the dust collection and filtration unit.

[0006] By adopting the above technical solution, in practical applications, the welding slag interception and protection unit formed by a pair of primary protective plates and barrier protective plates intercepts and protects against splashing welding slag, preventing welding slag from splashing onto the conveyor belt and causing ablation. Simultaneously, the protective wind wall formed by the negative pressure dust collector and the positive pressure spray plate not only provides auxiliary interception and protection against splashing welding slag but also guides welding fumes around the conveyor belt to be collected into the dust collection and filtration unit. This collection and filtration of welding fumes avoids adverse effects on the conveyor belt's operation, ensuring the stability of the conveyor belt in carrying and transporting materials or products.

[0007] Optionally, the belt conveyor assembly further includes a drive roller, a tension roller, multiple sets of support rollers, and a geared motor. The drive roller, tension roller, and multiple sets of support rollers are all rotatably connected to the frame. The multiple sets of support rollers are evenly distributed between the drive roller and the tension roller. The conveyor belt is sleeved on the outside of the drive roller, tension roller, and multiple sets of support rollers. The geared motor is fixedly mounted on one side of the frame, and the output end of the geared motor is fixedly connected to the drive roller.

[0008] By adopting the above technical solution, in practical applications, the conveyor belt is tensioned and limited by the cooperation of the drive roller, tension roller and multiple sets of support rollers. The drive roller is driven to rotate by the geared motor, so that the conveyor belt moves in a cycle under the action of friction, thereby realizing the function of continuous conveying of materials or products.

[0009] Optionally, the splash protection assembly further includes a pair of mounting brackets, which are fixedly mounted on both sides of the frame, and the pair of primary protective plates are respectively fixedly connected to the pair of mounting brackets.

[0010] By adopting the above technical solution, the primary protective plate and the barrier protective plate are assembled and connected using an assembly frame.

[0011] Optionally, the barrier protection plate includes a fixed frame, a visual protection plate, and a pair of adaptive side plates. The upper and lower ends of the fixed frame are provided with guide parts for assembling and fixing the negative pressure dust collection component and the positive pressure spray plate. The visual protection plate is fixedly installed inside the fixed frame, and the pair of adaptive side plates are symmetrically hinged on both sides of the fixed frame.

[0012] By adopting the above technical solution, in practical applications, the fixed frame and the visual protective plate work together to block and protect against spattering welding slag. Simultaneously, the visual protective plate avoids obstructing the view. The use of a pair of adaptive side plates further enhances the effectiveness of blocking and protecting against spattering. Furthermore, the angle or size of the adaptive side plates can be adjusted according to actual conditions, improving the flexibility and effectiveness of the protective plate.

[0013] Optionally, the dust collection and filtration unit includes a dust collection and filtration box and a pair of stepped filters. The dust collection and filtration box is a box-type component. The pair of stepped filters are symmetrically fixed inside the dust collection and filtration box. The pair of stepped filters cooperate to form a dust filtration chamber. The opposite sides of the pair of stepped filters cooperate with the dust collection and filtration box to form a pair of filter guide chambers. The mesh size of the pair of stepped filters increases step by step from the dust filtration chamber to the filter guide chamber.

[0014] By adopting the above technical solution, the dust collection and filter box is used to provide a dust filtration space, and a pair of stepped filter screens are used to filter the dust-laden gas collected in the dust collection and filter box.

[0015] Optionally, the dust collection and filtration unit further includes a pair of guide hoods and multiple sets of exhaust fans. The pair of guide hoods are symmetrically fixed on both sides of the dust collection and filtration box and are respectively connected to a pair of filter guide cavities. The size of the pair of guide hoods away from the dust collection and filtration box is smaller than the size of the other end. The multiple sets of exhaust fans are respectively fixed inside the pair of guide hoods, and the air inlet side of the multiple sets of exhaust fans is facing the filter guide cavity.

[0016] By adopting the above technical solution, the guide hood is used to assemble and fix the exhaust fan and guide the gas flow. By controlling the operation of multiple sets of exhaust fans, the air in the filter guide cavity is continuously discharged, thereby creating a negative pressure in the dust filter cavity for collecting welding fumes.

[0017] Optionally, the dust collection and protection assembly further includes a return baffle and a negative pressure drainage pipe. The return baffle is fixedly installed at the upper opening of the negative pressure dust collection component. One end of the negative pressure drainage pipe is connected to the negative pressure dust collection component, and the other end of the negative pressure drainage pipe is connected to the dust filter chamber.

[0018] By adopting the above technical solution, a backflow baffle is installed to limit the backflow of welding slag and welding fumes collected in the negative pressure dust collector, preventing secondary splashing of welding slag and welding fumes under the action of airflow. A negative pressure drainage pipe connects the negative pressure dust collector to the dust filter chamber of the dust collection and filter box, so that the welding slag blocked by the barrier plate and the welding fumes around the barrier plate can be collected into the dust filter chamber under the action of negative pressure along the negative pressure drainage pipe, thereby avoiding the adverse effects of welding slag and welding fumes on the operation of the conveyor belt.

[0019] Optionally, the dust collection and protection assembly further includes a guide pipe and a pair of air delivery pipes. The guide pipe is fixedly installed above the barrier plate and connected to the positive pressure spray plate. The pair of air delivery pipes are symmetrically arranged on both sides of the guide pipe and are connected to the guide pipe. The other end of the pair of air delivery pipes is connected to a pair of air guides respectively.

[0020] By adopting the above technical solution, in practical applications, the air in the filter guide cavity is transported to the guide pipe along the guide shroud and the conveying air pipe. This facilitates the subsequent formation of a protective wind wall on one side of the barrier and protection plate through the combination of positive pressure spray plate exhaust and negative pressure dust collection component suction. This not only helps the barrier and protection plate to block and protect against splashing welding slag, but also helps to collect welding fumes around the conveyor belt.

[0021] Optionally, the cleaning unit includes a dust-collecting plate and a flexible cleaning layer. The dust-collecting plate is a plate-shaped component with openings on both sides. The dust-collecting plate is fixedly installed above the dust collection and filter box. The flexible cleaning layer is fixedly installed above the dust-collecting plate and is adapted to the lower side of the conveyor belt.

[0022] By adopting the above technical solution, the flexible cleaning layer is assembled and fixed by the dust collection plate, and the welding fumes adhering to the surface of the conveyor belt are cleaned by the relative movement between the flexible cleaning layer and the conveyor belt.

[0023] Optionally, the lower opening of the dust collection plate is connected to the dust filter chamber, the flexible cleaning layer is arranged in a U-shape, and the flexible cleaning layer is fixedly disposed at the upper opening of the dust collection plate.

[0024] By adopting the above technical solution, in practical applications, the welding fumes swept out by the relative movement of the flexible cleaning layer and the conveyor belt are transported along the dust collection plate to the dust filter chamber for cleaning and filtration.

[0025] In summary, the embodiments of the present invention provide a welding fume control belt conveyor line, which includes at least one of the following beneficial technical effects: 1. The welding slag blocking and protection unit blocks and protects against the splashing welding slag, preventing the welding slag from splashing onto the belt and causing ablation. At the same time, the blocking and protection plate can be adaptively adjusted according to the actual situation, improving the protection effect of the belt. 2. By combining the negative pressure dust collection component with the positive pressure spray plate to form a protective wind wall, it can not only help the protective plate to block and protect the splashing welding slag, but also guide and collect the welding fumes around the protective plate, greatly reducing the risk of welding fumes adhering to the conveyor belt. 3. The negative pressure cleaning unit cleans and collects the welding fumes adhering to the belt surface, reducing the adverse effects of welding fumes on belt operation and improving the stability of belt conveying.

[0028] The following is in conjunction with the appendix Figures 1 to 8 This application will be described in further detail.

[0029] Combination Figure 1 and Figure 2 This application discloses a welding fume control belt conveyor line, including: a belt conveyor assembly 1, an anti-spatter protection assembly 2, and a dust collection and protection assembly 3. In practical applications, the anti-spatter protection assembly 2 protects the belt conveyor assembly 1 from welding slag. Simultaneously, the cooperation between the anti-spatter protection assembly 2 and the dust collection and protection assembly 3 collects and filters welding fumes around the belt conveyor assembly 1, ensuring the operational stability of the belt conveyor assembly 1.

[0030] Combination Figure 1 and Figure 5 The belt conveyor assembly 1 includes a frame 101, a conveyor belt 102, a drive roller 103, a tension roller 104, multiple sets of support rollers 105, and a geared motor 106. The conveyor belt 102 is disposed inside the frame 101. The drive roller 103, tension roller 104, and multiple sets of support rollers 105 are all rotatably connected to the frame 101. The multiple sets of support rollers 105 are evenly distributed between the drive roller 103 and the tension roller 104. The conveyor belt 102 is sleeved on the outside of the drive roller 103, tension roller 104, and multiple sets of support rollers 105. The geared motor 106 is fixedly disposed on one side of the frame 101, and the output end of the geared motor 106 is fixedly connected to the drive roller 103. In practical applications, the conveyor belt 102 is tensioned and limited by the cooperation of the drive roller 103, tension roller 104 and multiple sets of support rollers 105. The drive roller 103 is driven to rotate by the reduction motor 106, so that the conveyor belt 102 moves in a cycle under the action of friction, thereby realizing the function of continuous conveying of materials or products.

[0031] Combination Figure 1 and Figure 2The anti-splash protection component 2 is mounted on the outside of the frame 101. The anti-splash protection component 2 includes a pair of primary protective plates 201, a blocking protective plate 202, and a pair of mounting brackets 203. In practical applications, the pair of mounting brackets 203 are symmetrically fixed on both sides of the frame 101, and the pair of primary protective plates 201 are respectively fixed above the mounting brackets 203 using bolt connections / welding. The pair of primary protective plates 201 provide initial protection for the conveyor belt 102. Simultaneously, considering the surrounding conditions, the blocking protective plate 202 is mounted on the side of the conveyor belt 102 corresponding to the welding station. The blocking protective plate 202 blocks and protects against splashed welding slag, preventing welding slag from splashing onto the conveyor belt 102 and causing ablation.

[0032] Combination Figure 1 A pair of primary protective plates 201 are symmetrically arranged on both sides of the frame 101, providing initial protection for the conveyor belt 102. A barrier protective plate 202 is detachably fixed on the side of the frame 101 corresponding to the welding station, and together with the pair of primary protective plates 201, forms a slag barrier protection unit, which provides slag barrier protection for the conveyor belt 102.

[0033] Combination Figure 1 A pair of assembly frames 203 are fixedly installed on both sides of the frame 101. A pair of primary protective plates 201 are fixedly connected to the pair of assembly frames 203 respectively. The primary protective plates 201 and the barrier protective plates 202 are assembled and connected through the assembly frames 203.

[0034] Combination Figure 1 and Figure 2 The barrier and protective plate 202 includes a fixed frame 2021, a visual protective plate 2022, and a pair of adaptive side plates 2023. Both the upper and lower ends of the fixed frame 2021 are provided with guide portions for assembling and fixing the negative pressure dust collector 302 and the positive pressure spray plate 303. The visual protective plate 2022 is fixedly installed within the fixed frame 2021, and the pair of adaptive side plates 2023 are symmetrically hinged to both sides of the fixed frame 2021. The fixed frame 2021 and the visual protective plate 2022 work together to block and protect against splashing welding slag. Simultaneously, the visual protective plate 2022 avoids obstructing the view caused by the barrier and protective plate 202. The pair of adaptive side plates 2023 improves the effectiveness of blocking and protecting against splashing welding slag. Furthermore, the angle or size of the adaptive side plates 2023 can be adjusted according to actual conditions, improving the flexibility and effectiveness of the barrier and protective plate 202.

[0035] Among them, the 2022 visual protective panel uses transparent acrylic sheet.

[0036] Combination Figure 2, Figure 3 , Figure 5 and Figure 6 The dust collection and protection assembly 3 is installed in conjunction with the assembly frame 203. The dust collection and protection assembly 3 includes a dust collection and filtration unit 301, a negative pressure dust collector 302, a positive pressure spray plate 303, and a cleaning unit 304. The dust collection and filtration unit 301 has two suction ports and two air outlets. In practical applications, the negative pressure dust collector 302, in conjunction with one suction port, can collect welding fumes and weld slag behind the barrier plate 202 under negative pressure. Simultaneously, the positive pressure spray plate 303 expels air from the dust collection and filtration unit 301, forming a protective air wall on one side of the barrier plate 202, further improving the protection effect of the barrier plate 202 on the conveyor belt 102. Furthermore, the cleaning unit 304, through its interaction with the conveyor belt 102, cleans and collects welding fumes adhering to the outer surface of the conveyor belt 102.

[0037] Combination Figure 5 and Figure 6 The dust collection and filtration unit 301 includes a dust collection and filtration box 3011 and a pair of stepped filter screens 3012. The dust collection and filtration box 3011 is a box-shaped component. The pair of stepped filter screens 3012 are symmetrically fixed inside the dust collection and filtration box 3011, forming a dust filtration chamber. The opposite sides of the pair of stepped filter screens 3012 cooperate with the dust collection and filtration box 3011 to form a pair of filtration guide chambers. The mesh size of the pair of stepped filter screens 3012 increases progressively from the dust filtration chamber to the filtration guide chamber. The dust collection and filtration box 3011 provides dust filtration space, and the pair of stepped filter screens 3012 filters the dust-laden gas collected in the dust collection and filtration box 3011.

[0038] It should be noted that the stepped filter 3012 is composed of filter screens with different mesh sizes, and different filter media can be selected and combined according to the actual situation.

[0039] Combination Figure 5 and Figure 6 The dust collection and filtration unit 301 also includes a pair of guide hoods 3013 and multiple sets of exhaust fans 3014. The pair of guide hoods 3013 are symmetrically fixed on both sides of the dust collection and filtration box 3011 and are respectively connected to a pair of filter guide chambers. The size of the end of the pair of guide hoods 3013 facing away from the dust collection and filtration box 3011 is smaller than the size of the other end. The multiple sets of exhaust fans 3014 are respectively fixed inside the pair of guide hoods 3013, and the air inlet side of the multiple sets of exhaust fans 3014 is facing the filter guide chamber. The guide hoods 3013 are used to assemble and fix the exhaust fans 3014 and guide the gas flow. By controlling the operation of the multiple sets of exhaust fans 3014, the air in the filter guide chamber is continuously discharged, thereby creating a negative pressure in the dust chamber for collecting welding fumes.

[0040] Combination Figure 2 Both the negative pressure dust collector 302 and the positive pressure spray plate 303 are fixedly connected to the assembly frame 203. The negative pressure dust collector 302 is connected to one suction port of the dust collection and filtration unit 301, and the positive pressure spray plate 303 is connected to two air outlets of the dust collection and filtration unit 301. The negative pressure dust collector 302 and the positive pressure spray plate 303 cooperate to form a protective air wall. The protective air wall not only assists in blocking and protecting the splashing welding slag, but also guides the welding fumes around the conveyor belt 102 to be collected into the dust collection and filtration unit 301. By collecting and filtering the welding fumes, the adverse effects of welding fumes on the operation of the conveyor belt 102 are avoided. In addition, the presence of the protective air wall can accelerate the air circulation speed on one side of the visual protective plate 2022, which can cool and clean the visual protective plate 2022, and prevent the splashing welding slag from directly colliding with the visual protective plate 2022, thus ensuring the service life and surface finish of the visual protective plate 2022.

[0041] Combination Figure 7 and Figure 8 The dust collection and protection component 3 also includes a return baffle 305 and a negative pressure drainage pipe 306. The return baffle 305 is fixedly installed at the upper opening of the negative pressure dust collection component 302. By setting the return baffle 305, the welding slag and welding fumes collected in the negative pressure dust collection component 302 are backflowed and limited, so as to avoid the welding slag and welding fumes from splashing again under the action of airflow.

[0042] Combination Figure 7 and Figure 8 One end of the negative pressure drainage pipe 306 is connected to the negative pressure dust collection component 302, and the other end of the negative pressure drainage pipe 306 is connected to the dust filter chamber. By using the negative pressure drainage pipe 306 to connect the negative pressure dust collection component 302 to the dust filter chamber of the dust collection and filter box 3011, the welding slag blocked by the barrier plate 202 and the welding fumes around the barrier plate 202 can be collected into the dust filter chamber along the negative pressure drainage pipe 306 under the action of negative pressure, thereby avoiding the adverse effects of welding slag and welding fumes on the operation of the conveyor belt 102.

[0043] Combination Figure 2 and Figure 3The dust collection and protection component 3 also includes a guide pipe 307 and a pair of air conveying pipes 308. The guide pipe 307 is fixedly installed above the barrier protection plate 202 and is connected to the positive pressure spray plate 303. The pair of air conveying pipes 308 are symmetrically arranged on both sides of the guide pipe 307 and are both connected to the guide pipe 307. The other ends of the pair of air conveying pipes 308 are respectively connected to a pair of guide hoods 3013. This allows the air in the filtered guide cavity to be transported along the guide hoods 3013 and the air conveying pipes 308 into the guide pipe 307, facilitating the subsequent formation of a protective wind wall on one side of the barrier protection plate 202 through the combined exhaust of the positive pressure spray plate 303 and the suction of the negative pressure dust collection component 302. This not only helps the barrier protection plate 202 to block and protect against splashing welding slag, but also helps to collect welding fumes around the conveyor belt 102.

[0044] Combination Figure 3 , Figure 7 and Figure 8 The cleaning unit 304 is fixedly mounted above the dust collection and filtration unit 301 and is configured to cooperate with the frame 101. The cleaning unit 304 is connected to another suction port of the dust collection and filtration unit 301. The cleaning unit 304 includes a suction plate 3041 and a flexible cleaning layer 3042. The suction plate 3041 is a plate-shaped component with openings on both sides and is fixedly mounted above the dust collection and filtration box 3011. The flexible cleaning layer 3042 is fixedly mounted above the suction plate 3041 and is adapted to the lower side of the conveyor belt 102. The flexible cleaning layer 3042 is assembled and fixed by the suction plate 3041, and the welding fumes adhering to the surface of the conveyor belt 102 are cleaned by the relative movement of the flexible cleaning layer 3042 and the conveyor belt 102.

[0045] It should be noted that the lower opening of the suction plate 3041 is connected to the dust filter chamber, and the flexible cleaning layer 3042 is arranged in a U-shape and is fixedly installed at the upper opening of the suction plate 3041. The welding fumes swept out by the relative movement of the flexible cleaning layer 3042 and the conveyor belt 102 are transported along the suction plate 3041 to the dust filter chamber for cleaning and filtration.

[0046] In practical use, a pair of assembly frames 203 are symmetrically fixed on both sides of the frame 101, and a pair of primary protective plates 201 are fixed on top of the assembly frames 203 by bolt connection / welding, providing initial protection for the conveyor belt 102. Simultaneously, considering the surrounding conditions, a barrier protective plate 202 is assembled on the side of the conveyor belt 102 corresponding to the welding station, blocking and protecting against splashing welding slag. Meanwhile, a dust collection and filtration unit 301 is fixedly assembled below the conveyor belt 102. A negative pressure dust collection component 302 is connected to the dust collection and filtration unit 301's filter chamber via a negative pressure drainage pipe 306. A positive pressure spray plate 303 is connected to a pair of filter guide chambers of the dust collection and filtration unit 301 via a conveying air pipe 308 and a guide hood 3013.

[0047] During operation, the drive roller 103 is driven to rotate by controlling the operation of the geared motor 106, so that the conveyor belt 102 moves in a cycle under the action of friction, and the material or product is continuously conveyed by the cyclic movement of the conveyor belt 102.

[0048] During the operation of the conveyor belt 102, a welding slag interception and protection unit formed by a pair of primary protection plates 201 and barrier protection plates 202 intercepts and protects against splashing welding slag. Simultaneously, by controlling the operation of multiple sets of exhaust fans 3014, air is continuously drawn out of the filter guide chamber, creating a negative pressure within the dust filter chamber for welding fume collection. The negative pressure dust collector 302, in conjunction with the negative pressure drainage pipe 306, collects the welding fumes and intercepted welding slag around the barrier protection plates 202 into the dust filter chamber for filtration.

[0049] In addition, the filtered air in the pair of filter guide chambers can be transported to the positive pressure spray plate 303 along the guide hood 3013, the conveying air pipe 308 and the guide pipe 307. By spraying air from the positive pressure spray plate 303 and drawing air from the negative pressure dust collection unit 302, a protective wind wall is formed on one side of the barrier and protection plate 202. The protective wind wall can not only assist in blocking and protecting the splashing welding slag, but also guide the welding fumes around the conveyor belt 102 to be collected into the dust collection and filter unit 301. By collecting and filtering the welding fumes, the adverse effects of welding fumes on the operation of the conveyor belt 102 are avoided. In addition, the protective wind wall can accelerate the air circulation speed on one side of the visual protective plate 2022, which can cool down the visual protective plate 2022 and clean it with air blowing. It can also prevent the welding slag from directly colliding with the visual protective plate 2022, ensuring the service life and smoothness of the visual protective plate 2022. Through the cooperation of the anti-splash protection component 2 and the dust collection protection component 3, the conveyor belt 102 can continuously transport materials or products in the welding processing environment.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
