Description

Technical Field

[0001] This invention belongs to the field of pyrotechnics manufacturing and is applied to the process of removing and collecting floating propellant from dangerous explosive charges used in pyrotechnics. It relates to a device for removing and collecting floating propellant from dangerous explosive charges used in pyrotechnics. Background Technology

[0002] Some military pyrotechnics and civilian detonators are manufactured using a propellant loading process, where pre-formed propellant charges are loaded into the casing using equipment before proceeding to the next step. However, propellant charge production often employs a pressing method, where hazardous pyrotechnic agents are pressed using molds. After forming, the surface of the propellant charge often contains loose propellant. This loose propellant can flow into the product assembly process, posing safety and quality risks. Current technology involves manual removal of this loose propellant from the propellant charge, using a special sieve to separate the charges and employing compressed air to purge and remove the loose propellant from the surface.

[0003] The manual sieving method for removing floating chemicals relies solely on human experience for effectiveness. During product pouring, sieving, and collection, the hazardous chemical column is affected by multiple factors such as friction, impact, and static electricity, posing significant safety hazards. Furthermore, the use of compressed air for purging prevents the targeted collection and treatment of floating chemicals, easily leading to secondary safety risks. Summary of the Invention

[0004] This invention provides a device for removing and collecting floating explosives from hazardous explosive charges used in pyrotechnics. This solves the problems of existing methods where floating explosives are removed manually, which poses significant safety hazards and the lack of collection and passivation of the treated explosives, easily leading to secondary safety risks.

[0005] This invention utilizes automation and mechanization technologies, employing multiple measures such as mechanical vibration, sieving, compressed air purging, and negative pressure filtration collection. It has functions including feeding hazardous drug columns, sieving, removing and collecting floating drugs, and collecting products, thereby removing floating drugs from drug columns and improving product quality.

[0015] First, this invention effectively removes floating explosives from the surface of hazardous explosive charges used in pyrotechnics, solving production safety and product quality problems caused by floating explosives. Second, during the process of treating floating explosives, this invention effectively prevents diffusion and collects the explosives, preventing secondary safety risks caused by the diffusion of floating explosives.

[0016] Specifically, the workbench is the foundation of the equipment, with a solenoid valve control box placed inside the cabinet below the workbench, and other mechanisms installed above the workbench surface.

[0017] The material pouring mechanism is connected to the worktable via a support and includes a product box clamping device and a rotating pouring device. After the product box is clamped by the clamping device, the rotating device pours the medicine column out of the product box. The medicine column flows into the screening mechanism below through a slide.

[0018] The main function of the screening mechanism is to separate the floating medicine from the medicinal column through the vibration of the screen frame. The entire unit is connected to the worktable via a support. Its main components include a floating medicine collection frame and a screen frame. The floating medicine collection frame is supported on the support by spring plates, and the screen frame is located above and connected to the floating medicine collection frame. The power source of the screening mechanism comes from a high-frequency, low-friction cylinder below the screen frame, which is connected to the floating medicine collection frame through a linkage mechanism. The movement of the cylinder drives the movement of the floating medicine collection frame and the screen frame, thereby screening the floating medicine on the surface of the medicinal column into the floating medicine collection frame for collection. The medicinal column falls from the product outlet of the screen frame into the product box.

[0019] The flotation treatment mechanism primarily uses positive pressure air to purge and collect floating chemicals from the surface of the chemical column, then uses negative pressure to draw them into a flotation tank. The water in the tank dissolves, passivates, and collects the floating chemicals. The mechanism includes a flotation blowing device, a positive pressure protective cover, and a flotation tank. The flotation blowing device is connected to the worktable via a bracket and installed directly above the sieve frame. This device is connected to compressed air, which pulses through mechanical gaps to purge the chemical column below, causing the floating chemicals to fall into the collection frame. The positive pressure protective cover is connected to the worktable via a lifting cylinder. During operation, it covers the sieve frame and is connected to compressed air, which blows the floating chemicals into the collection frame, preventing their diffusion. The flotation tank, filled with water and installed separately from the equipment, uses a negative pressure generator to create negative pressure inside. The negative pressure port is connected to the flotation outlet of the collection frame via a hose, allowing the floating chemicals to enter the water inside the tank for dissolution, passivation, and collection.

[0020] The receiving mechanism is connected to the worktable via a lifting cylinder. A product collection box is placed on top of it. After the medicine column is removed by floating medicine, it falls from the product outlet of the sieve frame into the collection box, thus completing the product collection.
