[0002] At present, in the production process of powder, in order to reduce the destructive of accidental combustion and explosion in the production process, meet the safety standards of equipment of relevant industry, need to design explosion venting structure on equipment. The main purpose of explosion venting is to quickly release the pressure and flame generated by explosion when explosion occurs, so as to prevent explosion from causing greater damage to the surrounding environment and equipment. The commonly used explosion venting structure includes explosion venting plate, explosion venting window and collapsing explosion venting structure. Explosion venting plate is a common explosion venting device, usually installed on the surface or side of equipment, its working principle is that when explosion occurs, explosion venting plate will break or pop up under the set pressure, so as to quickly release the pressure generated by explosion. Explosion venting window is usually installed on the side or top of equipment. It automatically opens through mechanical structure when explosion occurs, and releases pressure. The collapsing explosion venting structure absorbs explosion energy and releases pressure by designing collapsible parts. The main disadvantage of these structures is that the explosion venting force is usually fixed, which leads to the fact that the equipment cannot adjust the corresponding explosion venting force according to the actual production situation, and there is certain safety hazard.

DETAILED DESCRIPTION
[0014] The utility model is further described below in combination with the drawings.
[0015] It should be noted that if the utility model involves directional indication language, such as up, down, left, right, front, back, and directional language, it is for the description of the relative position relationship between components, not the absolute position of the related components or the position relationship between components, and is only used to explain the relative position relationship between components, movement conditions and the like in a certain posture, if the posture changes, the directional indication also changes accordingly. If the utility model involves quantity language, such as "many", "multiple", "several" and the like, it specifically refers to two and more than two.
[0016] For example, Figure 1The utility model provides a kind of based on force balance regulation's explosion venting device, including detachable butt joint's top tank body 1 and folding mechanism 2, the folding mechanism 2 top periphery is equipped with mounting seat 3, mounting seat 3 is connected together with the lower end of top tank body 1 by magnetic attraction, the folding mechanism 2 is hung on mounting seat 3 by adjustable push rod 4, the folding mechanism 2 top is sealed with the lower end of top tank body 1 by adjustable push rod 4 by adjusting the push force size, and this is to adjust explosion venting force. Among them, top tank body 1 is fixedly connected with other components of production equipment, folding mechanism 2 is hung below top tank body 1 by magnetic attraction, and folding mechanism 2 is used to place explosive product. The recess with sealing pad is equipped in the folding mechanism 2 top or the lower end of top tank body 1, to realize the sealed butt joint of both.
[0017] The working principle of the utility model is: when the whole equipment is connected together, the folding mechanism 2 is hung below top tank body 1 by magnetic attraction, and the magnetic attraction force received is upward, and is recorded as F1; the gravity of folding mechanism 2, mounting seat 3 and product is downward, and is recorded as G; the push force of adjustable push rod 4 makes folding mechanism 2 abut with top tank body 1; the reaction force of top tank body 1 to folding mechanism 2 is downward, and is recorded as F2; when product explodes, folding mechanism 2 just overcomes explosion venting force and separates from top tank body 1; the explosion venting force required is f=F1-G-F2; therefore, after the magnetic attraction F1 is designed initially, the size of F2 is adjusted, and the explosion venting force f can be adjusted.
[0018] For adjustable push rod 4, the preferred scheme of the utility model is that the adjustable push rod 4 includes pull rod 41, spring 42 and force gauge 5; the outer wall of folding mechanism 2 is equipped with support plate 43; the upper end of pull rod 41 is fixedly connected with mounting seat 3; the lower end of pull rod 41 is equipped with screw thread; the lower end of pull rod 41 sequentially passes through support plate 43, spring 42 and limiting plate 44 and is connected with nut 45; the force gauge 5 is arranged between support plate 43 and spring 42 or between spring 42 and limiting plate 44. The compression amount of spring 42 is changed by rotating nut 45, so that the push force adjustment of adjustable push rod 4 is realized; the push force size is reacted in real time by force gauge 5, so that the accurate adjustment of push force is realized. Of course, the force size displayed by force gauge 5 is F2, and the sum of mounting seat 3 and product weight, which needs to be converted appropriately when calculating.
[0019] Because the structure form of folding mechanism 2 of different equipment is different, such as cylindrical structure or rectangular structure, it is also possible that folding mechanism 2 is connected with external equipment through another sliding mechanism, so the number and installation position of adjustable push rod 4 need to be adjusted according to actual situation. Under normal circumstances, in order to make folding mechanism 2 force balance, the adjustable push rod 4 preferably includes at least four, and is evenly distributed on the circumferential outer wall of folding mechanism 2.
[0020] For the force gauge 5, there are many force measurable devices on the market, and a suitable product can be selected according to requirements. The force gauge 5 selected by the utility model comprises an annular force sensor 51 and a display instrument 52 connected electrically, such as through wires. The annular force sensor 51 is sleeved on the pull rod 41, and the display instrument 52 is fixed on the outer wall of the folding mechanism 2. In this way, the installation position of the display instrument 52 can be set flexibly, and it is convenient for workers to observe and adjust the thrust.
[0021] For the magnetic connection of the top tank 1 and the mounting seat 3, there can be various ways, such as the connection of an electromagnet and an iron plate, the connection of a common magnet and an iron plate, or the connection of a magnet and a magnet. In order to simplify the structure, the preferred scheme of the utility model is that an iron plate 6 is fixed peripherally at the lower end of the top tank 1, and a magnet 7 that can be aligned and adsorbed with the iron plate 6 is fixed on the mounting seat 3. The magnet 7 is fixed on the independent mounting seat 3, which is convenient for processing and manufacturing. The top tank 1 is usually a steel structure, and the iron plate 6 can be welded directly on the top tank 1, which does not affect the original structure of the top tank 1 and the folding mechanism 2. In addition, in order to improve the magnetic attraction force, the iron plate 6 and the magnet 7 can be preferably annular structures or frame structures with matching cross sections.
[0022] The utility model adopts the magnetic attraction mode to connect the top tank 1 and the folding mechanism 2, and uses it as a blow-off position. The adjustable thrust rod 4 is used to adjust the abutting force between the top tank 1 and the folding mechanism 2, so as to offset the magnetic attraction force between them, so as to realize the size adjustment of the blow-off force. The whole device is convenient to install, debug and overhaul, can realize accurate adjustment of the blow-off force, improve the safety of the production equipment, can be used to modify the existing equipment, has good practicality and application prospect.
