Description

Technical Field

[0001] This utility model belongs to the field of explosive welding technology, specifically relating to a dust suppression device for explosive welding. Background Technology

[0002] Exploded composite plates are metal composite plates produced using the explosive bonding method (explosive welding method). Exploded composite plates generally refer to explosive metal composite plates. These composite plates are a new type of bimetallic, energy-efficient, and high-efficiency composite material with carbon steel as the base material and one or more layers of precious metals as cladding. They are formed by the impact force and ultra-high pressure of an explosion, bonding the plates together. They possess both the corrosion resistance and wear resistance of precious metals and the good weldability, formability, ductility, and thermal conductivity of carbon steel. After decades of development, explosive bonding between almost any metal can now be achieved. Exploded composite plates are now widely used in the petrochemical, metallurgical, salt and alkali production, hydraulic engineering, and nuclear industries.

[0003] During blasting operations, the large amount of smoke and dust generated after the explosion affects the working environment. Therefore, dust suppression devices are required. However, existing dust suppression devices are mostly simple wooden boards surrounding the explosives, with a layer of water covering the surface. In practical applications, securing the boards is inconvenient, and they are prone to misalignment under the pressure of the accumulated explosives, affecting the blasting effect. Furthermore, the water covering requires space for detonators, which can lead to water leakage and poor dust suppression. Cleaning the blasting platform afterwards is also difficult. Therefore, improvements are necessary to address these issues. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a dust suppression device for explosive welding. By setting a vibration-damping explosive platform on the support platform, the impact force during explosive welding is buffered, thereby reducing the impact of blasting vibration on the support platform. At the same time, a dust suppression hood with an internal spraying device is used to cover the support platform with sewage collection function and the vibration-damping explosive platform with composite plate inside, so as to achieve the purpose of effectively spraying the smoke and dust generated after the blast. This solves the water leakage problem caused by the unreasonable traditional spraying structure. The dust suppression effect is good, and the support platform with sewage collection function facilitates the centralized treatment of sewage after collection, solving the problem of difficult platform cleaning after the blast.

[0005] The technical solution adopted in this utility model is as follows: a dust suppression device for explosive welding, comprising a support platform with sewage collection function installed on the foundation, a vibration-damping explosive platform centrally located on the support platform, and a composite plate to be explosively welded placed on the vibration-damping explosive platform. A dust suppression hood is detachably fixed on the support platform, covering the vibration-damping explosive platform and the composite plate inside it. A spraying device located above the composite plate and used to spray the fumes generated during explosive welding is provided inside the dust suppression hood. The spraying device is connected to a connector located on the top surface of the dust suppression hood through a connecting pipe, and the connector is connected to a water supply pipe and a water tank connected to a water pump. A wire connected to the terminal block on the composite plate passes through the side wall of the dust suppression hood and leads to the outside.

[0006] The support platform is equipped with a water collection tank located on the outer periphery of the vibration-damping explosion platform, and the water collection tank is located inside the dust suppression hood.

[0007] Furthermore, a downwardly oriented guide ring plate is fixed on the inner wall of the lower end of the dust cover, and the lower end of the guide ring plate is located directly above the opening of the water collection tank.

[0008] Furthermore, the spraying device includes a dust-suppressing water bag and nozzles. A grid plate is fixed on the inner wall of the upper end of the dust-suppressing hood, and multiple nozzles extending out of the grid plate are evenly distributed on the bottom wall of the coil fixed to the grid plate. Multiple hanging rods located above the composite plate are fixed at the bottom of the grid plate, and the dust-suppressing water bag is suspended on the hanging rods. A rubber layer is filled between the grid plate and the inner top wall of the dust-suppressing hood, and one end of the coil is connected to a connector through a connecting pipe that penetrates the rubber layer and the top wall of the dust-suppressing hood.

[0009] Furthermore, the vibration-damping explosion platform includes a grooved plate with a groove on its upper surface and a plurality of vibration-damping springs evenly distributed between the grooved plate and the support platform. The upper and lower ends of the vibration-damping springs are fixedly connected to the grooved plate and the support platform, respectively. The groove of the grooved plate is filled with a layer of fine sand.

[0010] Furthermore, the extension plate extending outward from the lower outer edge of the dust cover is fixedly connected to the support platform by pre-embedded bolts.

[0011] Furthermore, the top of the dust cover is equipped with multiple lifting rings for easy hoisting.

[0021] Dust suppression devices used in explosive welding, such as Figure 1 As shown, the system includes a support platform 2 with sewage collection function, mounted on a foundation 1. A vibration-damping explosion platform 3 is centrally located on the support platform 2, and the composite plate 4 to be exploded and welded is placed on the vibration-damping explosion platform 3. A dust suppression hood 5 is detachably fixed to the support platform 2, enclosing the vibration-damping explosion platform 3 and the composite plate 4. Inside the dust suppression hood 5 is a spraying device located above the composite plate 4, used to spray away the fumes generated during the explosion welding. The spraying device is connected to a connector 6 located on the top surface of the dust suppression hood 5 via a connecting pipe, and the connector 6 is connected to a water supply pipe and a water tank via a water pump. A wire 7 connected to the terminal block on the composite plate 4 passes through... The side wall of the dust hood 5 leads to the outside; in the above structure, by setting a vibration-damping explosion platform 3 on the support platform 2, the impact force during explosive welding is buffered, thereby reducing the impact of blasting vibration on the support platform 2. At the same time, the dust hood 4 with an internal spraying device covers the support platform 2 with sewage collection function and the vibration-damping explosion platform 3 with composite plate 4 inside, so as to achieve the purpose of effectively spraying the smoke and dust generated after the blast, solving the water leakage problem caused by the unreasonable traditional spraying structure, and the spraying dust suppression effect is good. The support platform 2 with sewage collection function is convenient for centralized treatment after sewage collection, solving the problem of difficult platform cleaning after the blast.

[0022] To facilitate the treatment of wastewater after spraying, a water collection trough 8 is specially made on the support platform 2, located on the outer periphery of the vibration-damping explosion platform 3, and the water collection trough 8 is located inside the dust cover 5. Since the gas generated during explosive welding contains pollutants, the setting of the water collection trough 8 is conducive to the centralized collection of wastewater, which facilitates the centralized treatment of wastewater in the later stage and avoids the diffusion of pollutants in the water after spraying. Specifically, a diagonally downward-oriented guide ring plate 13 is fixed on the lower inner wall of the dust cover 5, and the lower end of the guide ring plate 13 is located directly above the opening of the water collection trough 8, which is used to reverse the water sprayed from the upper outer side of the water collection trough 8 into the water collection trough 8. In order to improve the connection strength of the guide ring plate 13, multiple reinforcing ribs are fixed on the inner wall of the dust cover 5 and fixed to the bottom surface of the middle part of the guide ring plate 13, which improves the strength of the guide ring plate 13 and reduces the impact of airflow impact on its connection strength during explosive welding.

[0023] The specific structure of the spraying device is as follows: The spraying device includes a dust-suppressing water bag 9 and nozzles 10. A grid plate 11 is fixed on the inner wall of the upper end of the dust-suppressing hood 5, and multiple nozzles 10 extending out of the grid plate 11 are evenly distributed on the bottom wall of the coil 12 fixed to the upper surface of the grid plate 11. Multiple hanging rods located above the composite plate 4 are fixed at the bottom of the grid plate 11, and the dust-suppressing water bag 9 is suspended on the hanging rods. A rubber layer 15 is filled between the grid plate 11 and the inner top wall of the dust-suppressing hood 5, and one end of the coil 12 is connected to the connector 6 through a connecting pipe that penetrates the rubber layer 15 and the top wall of the dust-suppressing hood 5. During the explosion, the dust-suppressing water bag 9 ruptures under the impact force, and the water stored in it forms water mist due to the explosion, which quickly adsorbs the smoke and dust, achieving a dust suppression effect. Immediately afterwards, the water pump is started, and the multiple nozzles 11 on the coil 12 spray dust over a large area, which can quickly assist the water mist generated by the dust-suppressing water bag 9 in rapid dust suppression. The dust-suppressing water bag 9 can be made of soft materials such as plastic film, silicone, or rubber.

[0024] The specific structure of the vibration-damping explosion platform 3 is as follows: The vibration-damping explosion platform 3 includes a grooved plate 3-1 with a groove on its upper surface and multiple vibration-damping springs 3-2 evenly distributed between the grooved plate 3-1 and the support platform 2. The upper and lower ends of the vibration-damping springs 3-2 are fixedly connected to the grooved plate 3-1 and the support platform 2, respectively. The groove of the grooved plate 3-1 is filled with a fine sand layer 3-3. The support platform 2 is made of concrete and has a pre-embedded connecting plate. The lower end of the vibration-damping spring 3-2 is fixedly connected to the connecting plate at the corresponding position. The setting of the vibration-damping spring 3-2 and the fine sand layer 3-3 plays a buffering role against the impact force during explosive welding, thereby reducing the impact of blasting vibration on the support platform 2.

[0025] The extension plate extending outward from the lower outer edge of the dust cover 5 is fixedly connected to the support platform 2 by pre-embedded bolts; specifically, in order to facilitate the movement of the dust cover 5, multiple lifting rings 14 are provided on the top of the dust cover 5.

[0026] This technical solution has a simple structure, novel design, and convenient and quick operation. It greatly reduces the difficulty of cleaning the front surface before the next explosive welding, improves cleaning efficiency, has a good dust suppression effect, and also has a certain noise reduction effect, making it highly valuable.
