Firstly, pre-embedding an embedded plate on the ground surface, fixing the embedded plate through concrete, and exposing the upper surface of the embedded plate; welding a bottom plate with a threaded hole on the upper surface of the bottom of the reactor box to enable the threaded hole of the bottom plate to be consistent with the position of a hole on the bottom of the reactor box; the upper surface of the pre-plate is provided with a fixed block, the upper surface of the fixed block is flush with the upper surface of the bottom plate, and a pressing plate is welded on the upper surface of the fixed block; the bottom plate stretches out towards the reactor, a through hole is formed in the stretching part of the bottom plate, the through hole in the pressing plate is guaranteed to correspond to the threaded hole in the bottom plate in the welding process, and the bolt penetrates through the pressing plate and is connected with the threaded hole in the bottom plate in a rotating mode. In the above structure, preferably, a gap is left between the bottom of the reactor case and the fixing block and between the bottom plate and the fixing block.

In order to ensure the flush degree, when the device is installed, the bottom plate or the fixing block can be ground flat, namely, the fixing block is welded with the pressing plate or the bottom plate is connected with the pressing plate after being ground flat.

When the clamp plate is in place and fastened again, the original clamp plate is cut off, ground and welded again, and the cutting and grinding accuracy needs to be guaranteed so as to guarantee the firmness when the clamp plate is welded again.

The utility model discloses simple structure, whole structure comprises bottom plate, clamp plate, fixed block and bolt, and the structure is small and exquisite, guarantees under the prerequisite of welding precision and reliability that not only can satisfy the requirement of suppressing the reactor vibration, the dismouting of being convenient for moreover. From this, not only can greatly reduced the maintenance degree of difficulty and the cost of maintenance of equipment, its design process has still fully considered the actual problem of its each side such as the expend with heat and contract with cold of its firm degree and has fully satisfied practical requirement.

Detailed Description

Example 1:

fig. 1-3 reflect the structure of the present embodiment, with fig. 2 reflecting a front view of a set of fastening mechanisms and fig. 3 reflecting a side view of a set of fastening mechanisms. As shown in the figure, the present embodiment includes at least eight sets of fastening mechanisms, the number of which depends on the condition of the reactor itself, and generally at least two sets are used per side. Each fastening mechanism comprises a bottom plate 7 welded on the bottom 4 of the reactor 1, and two threaded holes corresponding to the holes on the bottom 4 of the reactor are formed in the bottom plate 7. Be provided with pre-buried board 3 of pre-buried in the concrete subaerial, the welding has fixed block 8 on pre-buried board 3, and the position of fixed block 8 flushes to bottom plate 7 upper surface, and the degree of flushing allows to have certain error, for example the error within 3 mm. When not satisfied, the raised portion of the bottom plate 7 or the fixing block 8 may be ground flat. The pressing plate 5 may be a flat plate and welded on the upper surface of the fixing block 8. In order to ensure the welding reliability, the outer side surface of the pressure plate 5 is positioned inside the upper surface of the fixed block 8, so that a step surface is formed between the outer side surface and the fixed block, the connecting area between the welding material and the fixed block is increased, and the connecting firmness is further increased. The pressing plate 5 extends towards the reactor, and two through holes are formed in the pressing plate and correspond to the threaded holes in the bottom plate 7. Two bolts 6 respectively pass through the through holes on the pressure plate 5 and are screwed with the bottom plate 7. The lower parts of the two bolts 6 extend through the bottom plate 7 into holes in the reactor tank bottom 4, thereby enhancing the stability thereof and reducing the possibility of movement thereof.

In the specific construction of the embodiment, firstly, the embedded plate 3 is embedded in the ground surface and fixed by concrete, and the upper surface of the embedded plate 3 is exposed; welding a bottom plate 7 with a threaded hole on the upper surface of the box bottom 4 of the reactor 1, so that the threaded hole of the bottom plate 7 is consistent with the hole on the box bottom 4 of the reactor; the upper surface of the embedded plate 3 is provided with a fixed block 8, the upper surface of the fixed block 8 is flush with the upper surface of the bottom plate 7, and the upper surface of the fixed block 8 is welded with a pressure plate 5; in order to ensure the level degree, the fixing block 8 or the bottom plate 7 can be polished before welding.
