Description

Technical Field

[0001] This invention relates to the field of explosive welding technology, and more particularly to an explosive energy confinement device. Background Technology

[0002] Explosive welding is a technique that uses the powerful shock wave generated by the explosion of explosives to cause the cladding metal and the base metal to collide at high speed and obliquely to generate a jet, which cleans the surface to be welded, thereby achieving metallurgical bonding between the base and the cladding. However, existing explosive welding equipment suffers from energy dissipation from the explosives and cannot effectively guide the energy to the working surface, resulting in low energy utilization of the explosives. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, one object of this invention is to provide an explosive energy confinement device that guides the energy generated by explosives to the upper part of a composite plate, thereby improving the utilization rate of explosive energy.

[0004] An explosive energy confinement device according to the present invention includes a tank and a workbench. The outer side of the tank is fixed by a bracket. The workbench is installed at the bottom of the inner side of the tank. A side confinement plate with a cavity in the middle is installed at the upper end of the workbench. A base plate, a cover plate, an explosive layer, and a water bag layer are arranged sequentially from bottom to top in the cavity. The base plate and the cover plate are fixed by a fixing rod. A detonator is installed in the middle of the explosive layer. An inwardly recessed guide groove is opened on the upper end of the side confinement plate near the cavity. A cover is provided above the side confinement plate. The upper outer end of the cover is connected to the upper inner end of the tank through a cylinder. An upper confinement plate is installed inside the cover. A sealing door is installed on the side wall of the tank.

[0005] Preferably, an installation cylinder is installed on the upper outer side of the cover, the upper end of the upper constraint plate is connected to the installation cylinder through a connecting post, a spring is installed between the upper end of the connecting post and the installation cylinder, and the upper end of the upper constraint plate is connected to the upper inner side of the cover through an elastic rubber post.

[0006] Preferably, the upper outer end of the cover and the upper inner end of the tank are both provided with support rod mounting grooves for inserting and fixing support rods.

[0007] Preferably, a vacuum pump is installed on the upper side of one side of the bracket, and the vacuum pump is connected to the inside of the tank through a gas pipeline.

[0008] Preferably, a nozzle is installed on the upper end of the side wall of the tank, the nozzle is connected to a water tank through a liquid pipe, and a liquid pump is installed at the connection between the water tank and the liquid pipe.

[0009] Preferably, a waste liquid tank is provided at the bottom of the tank, a waste liquid recovery pipe is installed at the lower end of the waste liquid tank, and a waste liquid recovery valve is installed at the outlet of the waste liquid recovery pipe.

[0010] Preferably, the upper end of the waste liquid tank is detachably equipped with a filter plate to prevent debris generated by the explosion from entering the waste liquid recovery pipe.

[0011] Preferably, the tank body includes a first base layer, a buffer layer, a heat insulation layer, and a second base layer arranged sequentially from the outside to the inside.

[0012] Preferably, the first base layer is provided with a rust-proof coating on the side near the outside of the tank.

[0013] Preferably, both the first base layer and the second base layer are made of composite steel plates.

[0014] The beneficial effects of this invention are as follows: by setting an upper constraint plate on the upper end of the explosive layer and placing the base plate and the cover plate inside the side constraint plate, and by setting an inwardly recessed guide groove on the upper end of the side constraint plate, the energy generated by the explosive is directed to the upper end of the cover plate, thereby improving the utilization rate of the explosive energy. At the same time, the upper end of the upper constraint plate absorbs the energy generated by the explosion through the action of elastic rubber columns and springs, preventing the device from being damaged by excessive impact force. Meanwhile, the energy absorbed by the elastic rubber columns and springs can be fed back to the explosion surface, improving the utilization rate of the explosion energy. At the same time, a vacuum pump is used to evacuate the tank, reducing the loss of explosion energy from contact with air. After the explosion welding is completed, liquid is sprayed through a nozzle to absorb the dust and exhaust gas escaping from inside the tank, preventing environmental pollution.

[0021] Reference Figure 1-3 An explosive energy confinement device includes a tank 2 and a workbench 19. The tank 2 is fixed to the outside by a bracket 1. The workbench 19 is installed at the bottom inside the tank 2. A side confinement plate 17 with a cavity in the middle is installed on the upper end of the workbench 19. The cavity is arranged from bottom to top as follows: a base plate 4, a cover plate 5, an explosive layer 6, and a water bag layer 7. The base plate 4 and the cover plate 5 are fixed by a fixing rod 1. A detonator is installed in the middle of the explosive layer 6. The side confinement plate 17 has an inwardly recessed part on the upper end near the cavity. The guide channel has a cover 15 above the side constraint plate 17. The upper outer end of the cover 15 is connected to the upper inner end of the tank 2 via a cylinder 9. An upper constraint plate 16 is installed on the inner side of the cover 15. A sealing door 25 is installed on the side wall of the tank 2. An installation cylinder 12 is installed on the upper outer end of the cover 15. The upper end of the upper constraint plate 17 is connected to the installation cylinder 12 via a connecting column 10. A spring 11 is installed between the upper end of the connecting column 10 and the installation cylinder 12. The upper end of the upper constraint plate 17 is connected to the cover via an elastic rubber column 8. The upper inner side of the body 15 is connected; the upper outer side of the cover 15 and the upper inner side of the tank 2 are respectively provided with support rod mounting grooves 13 for inserting and fixing support rods; a vacuum pump 3 is installed on the upper side of one side of the bracket 1, and the vacuum pump 3 is connected to the inside of the tank 2 through a gas pipeline; a nozzle 14 is installed on the upper side wall of the tank 2, and the nozzle 14 is connected to a water tank 22 through a liquid pipeline, and a liquid pump 21 is installed at the connection between the water tank 22 and the liquid pipeline; a waste liquid tank 24 is provided at the bottom of the tank 2. Waste liquid recovery pipe 23 is installed at the lower end, and waste liquid recovery valve is installed at the outlet of waste liquid recovery pipe 23; filter plate 20 is detachably installed at the upper end of waste liquid tank 24 to prevent debris generated by explosion from entering the interior of waste liquid recovery pipe 23; tank body 2 includes a first base layer 26, a buffer layer 28, a heat insulation layer 29, and a second base layer 30 arranged sequentially from the outside to the inside; anti-rust coating 27 is provided on the side of the first base layer 26 near the outside of tank body 2; the first base layer 26 and the second base layer 30 are both made of composite steel plate.

[0022] During operation, the base plate 4, the composite plate 5, the explosive layer 6, and the water bag layer 7 are sequentially placed inside the cavity of the side restraint plate 17.

At the same time, the upper constraint plate absorbs the energy generated by the explosion through the action of elastic rubber columns and springs, preventing the device from being damaged by excessive impact force. The energy absorbed by the elastic rubber columns and springs can also be fed back to the explosion surface, improving the utilization rate of the explosion energy. In addition, a vacuum pump is used to evacuate the tank, reducing the loss of explosion energy from contact with air. After the explosion welding is completed, liquid is sprayed through a nozzle to absorb the dust and exhaust gas escaping from inside the tank, preventing environmental pollution.
