Description

Technical Field

[0001] The invention belongs to the technical field of sodium-cooled fast reactor loading and reloading, and in particular relates to a quick connection mechanism for a transfer silo and a transition silo. Background Art

[0002] During the process of loading a large number of components into the demonstration fast reactor, it is necessary to frequently connect the transfer silo and the transition silo, and to establish a passage between the transition silo and the transfer silo while keeping the inside sealed from the outside. It is necessary to invent a quick connection mechanism between the transfer silo and the transition silo. Summary of the invention

[0003] The object of the present invention is to provide a transfer silo and a transition silo quick connection mechanism, which can realize the quick connection and sealing between the transfer silo and the transition silo during the large-scale loading and replacement process.

[0004] The technical solution of the present invention is as follows: a quick connection mechanism for a transfer silo and a transition silo, comprising a lower quick-release flange and an upper quick-release flange.

[0005] The upper quick-release flange is connected to the quick-release flange pressing block.

[0006] The upper quick-release flange is connected to the transfer silo by welding.

[0007] The lower quick-release flange is provided with a plurality of pressing blocks, and the cam-type locking rod is connected to the pressing blocks by a shaft with screws.

[0008] A pressing sheet is arranged between the shaft and the pressing block.

[0009] The lower quick-release flange is provided with a guide pin.

[0010] There are two guide pins.

[0011] The beneficial effect of the present invention is that the device can realize the rapid connection, sealing and disconnection of the transfer silo and the transition silo. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 This is a schematic diagram of the quick-release flange below;

[0014] Figure 3 This is a top view of the lower quick-release flange.

[0015] In the figure: 1 cam type locking rod, 2 guide pin, 3 shaft, 4 clamping plate, 5 lower quick release flange, 6 quick release flange pressure block, 7 upper quick release flange. DETAILED DESCRIPTION

[0016] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] A quick connection mechanism for a transfer silo and a transition silo comprises a lower quick-release flange 5 and an upper quick-release flange 7.

[0018] like Figure 1 As shown, a plurality of quick-release flange pressing blocks 6 are connected to the edge of the upper quick-release flange 7. The upper quick-release flange 7 is welded to the transfer silo.

[0019] like Figure 2 As shown, six pressure blocks are arranged along the circumferential edge of the lower quick-release flange 5, and the cam-type locking rod 1 is connected to the pressure block by a shaft 3 with a screw and can rotate around the shaft 3, and a pressure sheet 4 is arranged between the shaft 3 and the pressure block.

[0020] like Figure 3 As shown, two guide pins 2 are also provided along the circumference of the lower quick-release flange 5 .

[0021] The use process of the present invention is as follows:

[0022] When the upper quick-release flange 7 is aligned with the locating pin and fits with the lower quick-release flange 5, the cam-type locking rod 1 is rotated to make the clamping plate 4 press the quick-release flange block 6 to achieve quick connection. When the assembly is transported, the cam-type locking rod 1 is rotated to separate the clamping plate 4 from the quick-release flange block 6 to quickly separate the transfer silo and the transition silo.

[0023] The device adopts a quick-release flange connection and a guide pin guide to achieve rapid centering, and uses a cam-type locking rod to rotate and tighten to seal the upper flange of the transition bin and the lower flange of the transfer silo.

[0024] The working process of the present invention is as follows:

[0025] Step 1: Install the sealing ring at the interface of the transition chamber;

[0026] Step 2: Use a crane to align the transfer silo and transition silo with guide pins;

[0027] Step 3: Rotate the cam locking rod in the connection mechanism at the upper part of the transition bin to realize the locking function of the transfer silo and the transition bin;

[0028] Step 4: Reversely rotate the cam locking rod to unlock the transfer silo and transition silo;

[0029] Step 5: Operate the crane to separate the crane from the transfer silo.
