Figure 1-4 The technical solution of the utility model is further illustrated through specific implementation methods.

[0043] The filter is an important equipment to ensure the stable operation of the nuclear power plant. The water used by the nuclear power plant needs to pass through the filter to remove impurities and pollutants in the water. Therefore, in order to improve the quality and safety of water, the filter needs to be dismantled, inspected and cleaned regularly. Figure 1 The filter shown is mainly composed of a filter element 100, a filter top cover 200, a filter barrel 300 and other parts. The filter top cover 200 and the filter element 100 weigh about 1 ton, and the filter top cover 200 and the filter element 100 cannot be hoisted out as a whole for maintenance; the filter top cover 200 and the filter element 100 are connected by a coupling. If the filter top cover 200 is hoisted out alone, the filter element 100 will fall to the bottom of the filter when the coupling bolts are loosened, causing damage to the equipment.

[0044] In order to solve the above problems, the present invention provides a temporary filter element fixing device. Figure 1-3 As shown, the filter element temporary fixing device includes a support block 1, a bent rod 2, and a first limiting nut 3. The support block 1 is arranged on the filter cylinder 300, and a first through hole 121 is arranged on the support block 1. The bent rod 2 includes an adjusting portion 21 and a hook portion 22, and the adjusting portion 21 is provided with an external thread. The adjusting portion 21 is slidably arranged in the first through hole 121, and the hook portion 22 is located at the lower end of the adjusting portion 21 for hooking the filter element 100. The first limiting nut 3 is threadedly connected to the adjusting portion 21 and abuts against the upper end surface of the support block 1.

[0045] The filter element temporary fixing device provided in this embodiment can temporarily fix the filter element 100 to ensure that the equipment can be disassembled for maintenance. In detail, when checking and cleaning the filter, first, separate the filter top cover 200 from the filter cylinder 300, lift the filter top cover 200 and the filter element 100 by 40cm-50cm, and use sleepers to temporarily support the filter top cover 200 to ensure the installation space of the temporary fixing device and the safety of the maintenance process. Then, a plurality of support blocks 1 are evenly arranged on the upper end of the filter cylinder 300 along the circumferential direction. Then, the upper adjustment portion 21 of the bent rod 2 is passed from the lower end face of the support block 1 to the upper end face, and is passed through the first through hole 121, the first limiting nut 3 is sleeved on the adjusting portion 21, the hook portion 22 hooks the lower end of the filter element 100, and finally the first limiting nut 3 is tightened so that the first limiting nut 3 abuts against the upper end face of the support block 1, and the temporary fixing of the filter element 100 is completed. If the filter is tilted after the temporary filter element fixing device is installed, it can be adjusted by the first limit nut 3. After adjustment, the coupling fixing bolt can be removed to fix the filter element 100 and separately lift the filter top cover 200 and the filter element 100, which not only ensures that the filter can be disassembled for maintenance, but also improves the safety and reliability of the maintenance process.

[0046] Optionally, the number of support blocks 1 can be three, four, five, etc. In this embodiment, the number of support blocks 1 is three, and adjacent support blocks 1 are evenly arranged on the filter cylinder 300 at intervals of 120°, ensuring the connection strength between the temporary fixing device and the filter cylinder 300, as well as the stability of the hooking filter element 100, while facilitating installation.

The position of the adjusting portion 21 at the first through hole 121 can be adjusted through the first through hole 121, so that the temporary fixing device is suitable for filter cylinders 300 of different sizes.

[0050] In order to further ensure the strength of the bent rod 2 and the stability of the hook portion 22 hooking the filter element 100, the adjustment portion 21 and the hook portion 22 are an integrally formed structure. In this embodiment, the bent rod 2 is processed by hot bending, the hook portion 22 has high strength, and the deformation and cracks of the hook portion 22 can be reduced.

[0051] Optionally, the filter element temporary fixing device further comprises a compression compensating member 5, which is sleeved on the fastening assembly 4 and abuts against the upper end surface of the support block 1, such as Figure 4As shown, the compression compensating member 5 is provided with a second through hole 51, and the fastening assembly 4 fixes the support block 1 to the filter cylinder 300 through the connecting hole 111 and the second through hole 51. The compression compensating member 5 can protect the fastening assembly 4 from damage and increase the installation and disassembly space of the support block 1. Specifically, when the temporary filter fixing device is installed, after the support blocks 1 are evenly arranged on the upper end of the filter cylinder 300, the compression compensating member 5 is placed on the upper end surface of the support block 1, and then the fastening assembly 4 is inserted into the connecting hole 111 and the second through hole 51, and the fastening assembly 4 is screwed to complete the fixing of the support block 1.

[0052] Preferably, in this embodiment, the compression compensating member 5 is made of steel, which has high strength, is economical and durable.

[0053] In this embodiment, the filter element temporary fixing device further includes a second limiting nut, which is threadedly connected to the adjustment portion 21 and abuts against the lower end surface of the support block 1, thereby improving the stability of the bent rod 2 hooking the filter element 100. When the bent rod 2 hooks the filter element 100, the second limiting nut is first sleeved on the adjustment portion 21, and the adjustment portion 21 passes from the lower end surface to the upper end surface of the support block 1 and is inserted into the first through hole 121, and then the first limiting nut 3 is sleeved on the adjustment portion 21, and the hook portion 22 hooks the lower end of the filter element 100, and finally the first limiting nut 3 and the second limiting nut are tightened to complete the temporary fixing of the filter element.

[0054] The specific installation process of the temporary filter element fixing device in this embodiment is described in detail below: First, separate the filter top cover 200 from the filter cylinder 300, lift the filter top cover 200 and the filter element 100 by 40cm-50cm, and use sleepers to temporarily support the filter top cover 200. Then, arrange multiple support blocks 1 evenly along the circumference on the upper end of the filter cylinder 300, place the compression compensation member 5 on the upper end surface of the support block 1, and the fastening component 4 is inserted into the connecting hole 111 and the second through hole 51. Screw the fastening component 4 to complete the fixation of the support block 1. Then, sleeve the second limiting nut on the adjustment part 21, and the adjustment part 21 is inserted into the first through hole 121 from the lower end surface to the upper end surface of the support block 1. The first limiting nut 3 is sleeved on the adjustment part 21, and the hook part 22 hooks the lower end of the filter element 100. Finally, tighten the first limiting nut 3 and the second limiting nut to complete the temporary fixation of the filter element. If the filter is tilted after installation, it can be adjusted by the first limit nut 3. After adjustment, the coupling fixing bolts can be removed to complete the disassembly and maintenance of the filter.
