Detailed Description
For the purposes of clarity, content, and advantages of the present utility model, a detailed description of the embodiments of the present utility model will be described in detail below with reference to the drawings and examples.
As shown in fig. 1, the explosion venting device for the single-base propellant powder manufacturing equipment of the embodiment comprises a base 1, a screw 3, a permanent magnet device 4 and an adjusting nut 6; the single-base propellant powder manufacturing equipment is integrally fixed on the equipment supporting structure 5, and the bottom of the single-base propellant powder manufacturing equipment is fixedly connected with the equipment supporting structure 5; the bottom of the single-base propellant powder manufacturing equipment is provided with a explosion venting port, and the edge of the explosion venting port is provided with a connecting point 2; the base 1 is a stainless steel plate which is horizontally arranged, the top of the base is provided with a plurality of mounting holes in the vertical direction, and a plurality of permanent magnet devices 4 are correspondingly fixed in the mounting holes one by one; the base 1 is fixed on the connecting point 2 through the permanent magnet device 4, is uniformly distributed in the length direction of the base and is used for providing fixed pulling force and ensuring the tight connection of the upper part and the lower part of the equipment, thereby closing the explosion venting port and not affecting the technological functions of the equipment.
The shape of the permanent magnet device 4 can be adjusted according to the shape of the production equipment, generally, a rectangular stainless steel block is used as the substrate 1, and a corresponding number of powerful permanent magnets are punched and embedded to provide the required pulling force for fixing the substrate 1.
The device supporting structure 5 is provided with a through hole in the vertical direction. The bottom of basement 1 is fixed with screw rod 3, screw rod 3 vertical setting, the bottom fixed connection of screw rod 3 and basement 1, the through-hole on the other end runs through equipment support structure 5, is connected with equipment support structure 5 through adjusting nut 6. The tension of the screw 3 can be further adjusted by rotating the adjusting nut 6.
In the normal production process, parameters such as the dead weight of manufacturing equipment, the weight of materials in the manufacturing equipment, the internal pressure of the manufacturing equipment and the like need to be calculated, the permanent magnet device 4 has larger magnetic force, the screw rod 3 and the adjusting nut 6 provide downward pulling force, and the following stress balance is formed:
total tension of permanent magnet device-screw tension = manufacturing equipment dead weight + weight of material in the equipment + maximum allowed air pressure inside the equipment.
