Description

Technical Field

[0001] This invention relates to the field of reactor technology, and in particular to a reactor body fixing structure. Background Technology

[0002] The fixing structure of the large parallel reactor body is a key design to ensure the stability of the reactor body, reduce noise and vibration, and ensure transportation safety. The fixing structure securely connects the reactor body to the oil tank, avoiding core vibration, displacement and noise caused by changes in current and magnetic field, as well as loosening, deformation and displacement of the reactor body during transportation.

[0003] Large parallel reactors were previously designed so that the reactor body was not fixedly connected to the tank, but placed directly inside the tank. The reactor body was restrained by using felt and cardboard to seal the gap between the side support plate on the upper part of the reactor body and the tank fixing plate. This method of restraining the reactor body displacement could meet functional requirements in most cases. However, when transportation conditions were not ideal, especially for export projects where sea conditions were harsh, the waves were large, and the transportation period was long, the above-mentioned restraining measures for the reactor body became obviously insufficient. In such cases, loosening, deformation, and displacement of the reactor body due to insufficient restraining measures often occurred, resulting in economic losses due to product repair or return to the factory.

[0004] Therefore, to address the above problems, a reactor body fixing structure can be designed. By simultaneously adding fixing structures to the upper and lower parts of the reactor body to apply bidirectional constraints in both longitudinal and lateral directions, the reactor body can be connected to the oil tank as a whole without relative displacement. Summary of the Invention

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example 1

[0018] This application can actually solve the problems of loosening, deformation and displacement of the reactor body caused by insufficient limiting measures in the fixed structure of the traditional reactor body; In this embodiment, according to Figures 1 to 6 As shown, it includes a lower fixing assembly located at the connection between the bottom of the vessel body and the bottom of the oil tank. The lower fixing assembly includes a positioning nut 1, a foot fixing plate 2, a foot insulating tube 3, a foot insulating pad 4, and a foot fastening bolt 5. The positioning nut 1 is fixedly installed at the bottom of the oil tank. The foot insulating pad 4 is provided on the upper end of the positioning nut 1. The foot fixing plate 2 is welded to the lower part of the vessel body. The foot fastening bolt 5 is provided on the upper end of the foot fixing plate 2. The foot insulating tube 3 is fitted on the outside of the foot fastening bolt 5. The foot fixing plate 2 is located between the foot insulating pad 4 and the foot insulating tube 3. The foot fastening bolt 5 passes through the foot fixing plate 2 and the foot insulating pad 4. The foot fastening bolt 5 and the positioning nut 1 are threadedly connected.

[0019] When the reactor body is placed inside the oil tank, the foot fixing plate 2 is placed on the foot insulating plate 4. The foot fastening bolt 5 with the foot insulating tube 3 is inserted into the foot fixing plate 2. The foot fastening bolt 5 is rotated to make the foot fastening bolt 5 threadedly connected to the positioning nut 1, thereby fixing the foot fixing plate 2. The foot insulating plate 4 tightens the gap between the foot fixing plate 2 and the positioning nut 1, effectively fixing the reactor body and preventing it from shaking up and down. The foot insulating plate 4 and the foot insulating tube 3 also achieve the effect of insulating the lower part of the reactor body from the oil tank.

[0020] Furthermore, an upper fixing assembly is provided at the connection between the top of the reactor body and the bottom of the tank cover. This upper fixing assembly includes a tank cover fixing plate 6, a tank cover insulating pad 7, a tank cover adjusting plate 8, a tank cover fastening bolt 9, a core clamp fastening bolt 10, a tank cover fastening nut 13, a core clamp fastening nut 15, a core clamp insulating tube 16, and a reactor body core clamp 17. The tank cover is fixedly mounted with the tank cover fixing plate 6. The tank cover insulating pad 7 and the tank cover adjusting plate 8 are located on the outer side of the tank cover fixing plate 6. The tank cover adjusting plate 8 is positioned between the tank cover insulating pad 7 and the tank cover fixing plate 6. The tank cover fastening bolt 9 is located on the outer side of the tank cover fixing plate 6. One end of the fastening bolt 9, which passes through the cover fixing plate 6, the cover insulating pad 7, and the cover adjusting cardboard 8, is provided with a matching cover fastening nut 13. The cover fastening bolt 9 and the cover fastening nut 13 are threadedly connected. The outer side of the cover insulating pad 7 is provided with a core clamp fastening bolt 10. The end of the core clamp fastening bolt 10 is provided with a core clamp fastening nut 15. The outer side of the device body is fixedly installed with a device body core clamp 17. The core clamp fastening bolt 10 passes through the cover insulating pad 7 and the device body core clamp 17 and is threadedly connected with the core clamp fastening nut 15. The outer side of the core clamp fastening nut 15 is fitted with a core clamp insulating tube 16.

[0021] The length of the cover insulating pad 7 is greater than the length of the cover fixing plate 6, which facilitates the staggered installation of the core clamp 17 and the cover fixing plate 6 on the cover insulating pad 7. The core clamp fastening bolt 10 passes through the cover insulating pad 7 and the core clamp 17 and is threadedly connected to the core clamp fastening nut 15 with the core clamp insulating tube 16, thereby fixing the core to the cover insulating pad 7. The cover fastening bolt 9 passes through the cover fixing plate 6, the cover adjusting cardboard 8 and the cover insulating pad 7 and is fixed by tightening the cover fastening nut 13. The cover adjusting cardboard 8 is used to tighten the gap between the cover fixing plate 6 and the core clamp 17, preventing the core from shifting due to back-to-back and left-to-right shaking. The core clamp insulating tube 16 and the cover insulating pad 7 are used to achieve insulation between the upper part of the core and the top cover of the tank.

[0022] Working principle: The reactor body is placed inside the oil tank. The foot fixing plate 2 is placed outside the foot insulating pad 4 on the positioning nut 1. Then, the foot fastening bolt 5 with the foot insulating tube 3 is screwed down. The lower part of the reactor body is fixed by the threaded connection between the foot fastening bolt 5 and the positioning nut 1. The foot insulating pad 4 fills the gap between the reactor body and the oil tank, which is highly adaptable. Then, the upper part of the reactor body is fixed. The iron core clamp fastening bolt 10 passes through the cover insulating pad 7 and is threadedly connected to the iron core clamp 17 of the reactor body and the iron core clamp fastening nut 15 with the iron core clamp insulating tube 16. This connects the cover insulating pad 7 to the reactor body. Then, the cover fastening bolt 9 passes through the cover fixing plate 6, the cover insulating pad 7, and the cover adjusting plate 8. By tightening the cover fastening bolt 9 and the cover fastening nut 13, the cover insulating pad 7 is fixed to the top cover of the oil tank. This insulates and fixes the upper part of the reactor body to the oil tank. The cover adjusting plate 8 fills the gap between the reactor body and the oil tank.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
