The quick connection locking device of the embodiment is composed of a valve transition flange component, a hopper transition flange component, an outer shell component and a cylinder of CDM2E32-100Z-M9B, is used between the valve and the hopper, realizes connection and locking of the valve and the hopper, and realizes a quick disassembly function. The valve transition flange assembly comprises a valve transition flange 19, an imitated external thread tooth section 11, a cylinder fixing plate 7, a cylinder 2 and a front end ring 9. Before the valve transition flange assembly works, the valve transition flange assembly and the valve 1 are fixedly connected together through 8M 18 multiplied by 18 bolts, and the connection position is sealed by an O-shaped ring with the model phi of 250 multiplied by 7. The hopper transition flange assembly consists of a hopper transition flange 18 and O-shaped sealing rings with the models of phi 295 multiplied by 7 and phi 236 multiplied by 7 respectively. The housing assembly comprises eight supporting ball bearings 15, a belleville spring 14, six segments of a simulated internal thread segment 10 and a housing 8. Before the operation, the lower end of the hopper 5 is fixedly connected with the shell component, the annular pressing plate 4 and the hopper transition flange component through 8M 18 multiplied by 18 bolts, and the connecting part of the hopper and the hopper transition flange is sealed by an O-shaped ring with the model phi of 250 multiplied by 7. The upper end of the hopper is connected with the cover 6, and the connection part is sealed by an O-shaped ring with the model diameter of 190 multiplied by 5.3.
In operation, the valve portion and the hopper portion are first butted. In the butt joint process, due to the positioning error of the crane, the upper part and the lower part can not realize complete coaxial line, and the quick butt joint can be realized by the conical surface matching between the valve transition flange 19 and the hopper transition flange 18 as the assembly guide. And inserting the pin shaft arranged on the shell 8 into the front end ring 9 to complete butt joint. Then, the cylinder contracts, the front end ring 9 drives the shell 8 to rotate clockwise by 20-22 degrees, and the six sections of the thread sections 11 imitating the external threads fixed on the inner side of the shell are matched with the six sections of the thread sections 10 imitating the internal threads fixed on the side surface of the valve transition flange 19, so that locking is realized. After locking, a closed cavity is formed inside, so that the internal vacuumizing operation can be realized, and the sealing effect is ensured. When the device is required to be loosened, after the internal vacuum is released to the atmospheric pressure, the cylinder is controlled to extend out through the electromagnetic valve, the front end ring 9 drives the shell 8 to rotate anticlockwise by 20-22 degrees, and at the moment, the six sections of the thread sections with the external threads imitating 11 fixed on the inner side of the shell are staggered with the six sections of the thread sections with the internal threads imitating 10 fixed on the side surface of the valve transition flange 19, so that the loosening is completed.
The shell subassembly can effectively prevent that impurity from falling into the mechanism inside at mechanism work in-process, causes mechanism damage or incident. Eight supporting ball bearings 15 in the shell component are supported between the shell 8 and the hopper transition flange 18, so that the friction force in the rotating process is reduced, and the service life of the device is prolonged. The belleville springs 14 are mounted between the support ball bearings 15 and the housing 8. Under the locking state, the belleville spring is compressed to generate elastic force, so that the locking force between the imitated external thread section 11 and the imitated internal thread section 10 is increased, and meanwhile, the cooperation between the imitated external thread section 11 and the imitated internal thread section 10 can be adjusted through the deformation of the belleville spring, so that the clamping is prevented, and the production efficiency is improved. The sealing groove used for mounting the O-shaped ring on the hopper transition flange is a dovetail sealing groove, the sealing groove structure can achieve the purpose that the sealing ring cannot fall off under the condition that the sealing surface is disengaged, sealing failure is caused by clearance bite or extrusion of the O-shaped ring in the working process, and the dovetail groove angle is selected for matching with other sizes and avoiding the condition that the O-shaped ring cannot be rebounded and cannot be completely taken out due to too small angle after being clamped.
