Description

Technical Field

[0001] The invention belongs to the technical field of destruction and relates to a device for destroying scrapped explosives by electric heating. Background Art

[0002] At present, domestically produced devices for destroying scrapped pyrotechnics use an open fuel combustion method. The feed port of the destruction device is normally open; the furnace structure of the destruction device mostly adopts the form of an inner tank layer, a heat insulation layer and a shell layer, and a manual slag unloading switch cover is provided at the bottom of the furnace body; the burner components of the destruction device are the combustion fire source and heat source for the pyrotechnic destruction operation of the destruction device, and are all embedded structures in the furnace body. Through manual feeding, the scrapped pyrotechnics are delivered to the feed port by a conveyor belt. After the scrapped pyrotechnics fall into the bottom of the furnace body, the flames sprayed by the fuel burner and the high temperature heat generated cause the scrapped pyrotechnics to explode, achieving the purpose of destruction. After the destruction operation is completed, the slag is manually unloaded and cleaned through the switch cover at the bottom of the furnace body.

[0003] The rated destruction equivalent of the pyrotechnic destruction device in the prior art is relatively small, and the single destruction equivalent is generally no more than 200gTNT, which cannot form a complete destruction coverage for large-equivalent scrapped pyrotechnics.

[0004] The inner layer of the furnace body of the destruction device is the main protective structural layer for the explosion-proof performance of the furnace body. It is easy to produce local penetration pits with radial depth, and the often open feeding port poses a safety hazard to the destruction operation of pyrotechnics.

[0005] The burner component of the destruction device is an embedded structure of the furnace body. It is the combustion fire source and heat source for the pyrotechnic destruction operation of the destruction furnace. During the pyrotechnic destruction operation, it is easy to have explosions in the furnace body due to the large equivalent, and smoke and waste residues will flow into the burner pipe, causing the burner to extinguish and be destroyed, resulting in high frequency of equipment maintenance and high cost of use. Summary of the invention

[0010] (III) Beneficial effects

[0011] The electric heating device for destroying scrapped explosives provided by the above technical solution has the following beneficial effects:

[0012] (1) The use of a feeding locking mechanism can ensure that the sealing effect of the upper furnace body assembly and the feeding mechanism cover assembly is intact, preventing the destruction residue of scrapped pyrotechnics and the leakage of radioactive gases from causing harm to the human body. Its structure fastens the upper furnace body assembly and the feeding mechanism cover through a locking ring assembly, which can reduce the hidden dangers of toxic and harmful gas leakage. Its mechanical structure, which is screwed together through a locking component, reducers on both sides, and a locking ring assembly, and then locks the threads at the connection between the upper furnace body assembly and the feeding mechanism cover assembly, can be screwed together through the external threads with opposite rotation directions set by the screw and the internal threads with opposite rotation directions set by the nut, and the locking ring assembly can be opened or closed at the same time, further reliably locking the upper furnace body assembly and the feeding mechanism cover assembly, preventing the safety hazard of furnace body leakage during the destruction of scrapped pyrotechnics. The structure of connecting the reducers on both sides through a universal shaft can make the locking components work together, ensuring that the locking mechanism of the present invention is sensitive in action, opens and closes smoothly, shortens the opening and closing time, and meets the needs of destroying scrapped pyrotechnics;

[0013] (2) The lifting and locking mechanism can ensure that the upper furnace body assembly is connected to the lifting mechanism cover assembly, which is in a closed state during operation and opened during maintenance, making it easy to maintain the furnace body;

[0014] (3) The upper furnace body locking mechanism can ensure the connection between the upper furnace body assembly and the middle straight tube section assembly of the furnace body. It is in a closed state during operation and opened during maintenance, which is convenient for furnace body maintenance;

[0015] (4) The lower furnace cover locking mechanism can ensure the sealing effect of the lower furnace cover assembly and the middle straight section assembly of the furnace body is intact, preventing the destruction residue of scrapped pyrotechnics and the leakage of radioactive gases from causing harm to the human body. Its structure locks the connection between the lower furnace cover assembly and the middle straight section assembly of the furnace body through the locking ring assembly, which can reduce the hidden danger of toxic and harmful gas leakage. It locks the threaded connection between the lower furnace cover assembly and the middle straight section assembly of the furnace body through the locking component, the reducers on both sides, and the locking ring assembly. The mechanical structure can be screwed together by the external thread with opposite rotation direction set by the lead screw and the internal thread with opposite rotation direction set by the nut, and the locking ring assembly can be opened or closed at the same time, and the lower furnace cover assembly and the middle straight tube section assembly of the furnace body can be further reliably locked to prevent the safety hazard of furnace body leakage during the destruction of scrapped pyrotechnics. The structure of the reducers on both sides connected by the universal shaft can make the locking assembly linked, ensuring that the locking mechanism of the present invention is sensitive in action, opens and closes smoothly, shortens the opening and closing time, and meets the needs of destroying scrapped pyrotechnics;

[0016] (5) The use of a feeding mechanism cover assembly can ensure that the scrapped pyrotechnics can be fed smoothly. The structure drives the servo electric cylinder through the servo motor and then drives the push plate, and the push plate pushes the scrapped pyrotechnics into the furnace body;

[0017] (6) The use of a lifting mechanism cover assembly can ensure that the scrapped pyrotechnics are well sealed in the furnace body, preventing the destruction residues and radioactive gases from leaking from the upper furnace body assembly to cause harm to the human body. Its structure controls the servo motor to drive the spiral lifter and then the lifting ball to the lowest position that can be reached, thereby achieving the sealing of the scrapped pyrotechnics in the furnace body, preventing the safety hazard of furnace body leakage during the destruction of the scrapped pyrotechnics;

[0018] (7) The lower furnace cover lifting mechanism can ensure the lower furnace cover assembly and prevent the destruction residues of scrapped pyrotechnics and the leakage of radioactive gas from causing harm to the human body. The structure drives the electric cylinder to lift the lower furnace cover through a servo motor. BRIEF DESCRIPTION OF THE DRAWINGS
