Water enters from the water inlet pipe 303 and is discharged from the drainage hole at the water outlet end of the water inlet pipe 303 into the water collecting chamber 307. Finally, the water in the water collecting chamber 307 flows into the water outlet pipe 304 from the water inlet hole at the water inlet end of the water outlet pipe 304 and is discharged from the water outlet pipe 304 to the outside of the silencer, thereby eliminating the sound of the water flow.

[0043] For details, please refer to Figure 4 and Figure 5The water inlet end of the water inlet pipe 303 is provided with a filter assembly 60, which includes a movable frame 601, a filter screen 602 and a limit block 603. The limit block 603 is arranged on the inner wall of the water inlet pipe 303, and the filter screen 602 is located in the water inlet pipe 303. The filter screen 602 is provided with an avoidance groove that matches the position of the limit block 603. The movable frame 601 is connected to the filter screen 602 to drive the filter screen 602 to rotate or move along the length direction of the water inlet pipe 303; the inner wall of the water inlet pipe 303 is provided with a filter screen 602. The elastic member 604 is generally a spring. The elastic member 604 is against the side of the filter 602 away from the movable frame 601. The movable frame 601 can be rotated to drive the filter 602 to rotate so that the avoidance groove of the filter 602 is aligned with the limit block 603. Then, the movable frame 601 is pulled to pull the filter 602 out of the water inlet pipe 303, so as to facilitate the cleaning of impurities on the filter 602, prevent the filter 602 from being blocked by impurities, and improve the structural stability of the filter assembly 60.

[0044] For details, please refer to Figure 2 and Figure 3 The water removal component 50 includes a movable ring 501, an adsorption net 502, and a heating coil 503.

According to actual needs, a corresponding number of adsorption nets 502 can be set, and these adsorption nets 502 can be set at both ends of the movable ring 501; the heating coil 503 is sleeved on the side of the movable ring 501, pushing and pulling the handle 402 to drive the movable rod 401 to move, thereby driving the water removal component 50 to move in the silencer area 102. The adsorption net 502 of the water removal component 50 can adsorb water stains in the silencer area 102. In addition, the heating coil 503 can be turned on by the corresponding control switch to evaporate the residual water stains in the silencer area 102.

[0045] For details, please refer to Figure 2 and Figure 6The silencer device also includes a sealing mechanism 70, which is arranged in the water inlet area 101. The sealing mechanism 70 includes a sealing plate 701 and a sealing tube 702. The sealing plate 701 is arranged on the inner wall of the storage cavity, and the sealing tube 702 is inserted into the sealing plate 701, and the sealing tube 702 is sleeved on the water inlet end of the silencer chamber 301. A movable baffle 703 is provided at the end of the sealing tube 702 away from the silencer chamber 301, and a driving member connected to the movable baffle 703 is provided in the sealing tube 702 to drive the movable baffle 703 to move and open or close the sealing tube 702. Since the sealing plate 701 blocks the water from continuing to flow, and the sealing tube 702 is sleeved on the water inlet end of the silencer chamber 301, water needs to pass through the sealing tube 702 to enter the silencer chamber 301. According to actual usage, the movable baffle 703 can be controlled by the driving member to move to realize the opening or closing of the sealing tube 702, which is convenient for controlling the water flow.

[0046] In one embodiment, not shown in the figure, the driving member includes a rotating shaft and a motor, one end of the rotating shaft is connected to the movable baffle 703, and the other end of the rotating shaft is connected to the driving end of the motor. The motor can drive the rotating shaft to rotate and drive the movable baffle 703 to rotate around the rotating shaft. When the movable baffle 703 is an integrated molding structure, the rotating shaft can be driven to rotate by the motor, thereby driving the movable baffle 703 to rotate around the rotating shaft, so that the sealing tube 702 is opened or closed. The overall structure is simple and the operation is convenient.

[0047] In another embodiment, please refer to Figure 6 and Figure 7 The driving member includes a rotating rod 704, a gear 705, a ring gear 706 and a transmission rod 707. One end of the rotating rod 704 is connected to the gear 705, and the other end of the rotating rod 704 is connected to the movable baffle 703. The gear 705 is meshed with the ring gear 706, and the ring gear 706 is connected to one end of the transmission rod 707.

[0048] Among them, not shown in the figure, the second partition 202 is provided with a threaded hole, and the end of the silencer chamber 301 away from the water inlet pipe 303 is provided with a mounting thread connected to the threaded hole. By rotating the silencer chamber 301, the mounting thread of the silencer chamber 301 can be separated from the threaded hole, thereby disassembling the silencer chamber 301. The operation is simple and can improve the assembly efficiency of the silencer device. At the same time, since the silencer chamber 301 is connected to the transmission block 708, when the silencer chamber 301 is rotated, the transmission block 708 rotates with the silencer chamber 301, which can drive the transmission rod 707 to drive the ring gear 706 to rotate, and the gear 705 rotates with the ring gear 706, and then the rotating rod 704 rotates, and finally the movable baffle 703 is rotated to close the sealing tube 702. That is, when the silencer chamber 301 is disassembled, the sealing tube 702 can be closed to prevent water from flowing into the silencer area. The operation is simple, the assembly efficiency is improved, and the stability of the overall structure is improved.

[0049] Specifically, see Figure 2 The silencer shell 10 includes an outer shell 106, an adsorbent cotton 107 and an inner shell 108 from the outside to the inside. The outer shell 106 can play a protective role, the inner shell 108 can play a supporting role, and the adsorbent cotton 107 can play a buffering and sound absorption role. The combination of the three can improve the structural stability of the silencer and improve the sound absorption performance of the silencer.

[0050] For details, please refer to Figure 1 and Figure 8 The sound-absorbing shell 10 is provided with a sound-absorbing sleeve 80, which includes an absorption shell 801, insulation cotton 802 and absorption cotton 803 from the outside to the inside, which can further enhance the sound-absorbing performance of the sound-absorbing device.

[0051] The use process of the silencer device of the nuclear power auxiliary water supply system provided by the present invention is as follows:

[0052] The water inlet 104 of the silencer shell 10 is connected to the water inlet main pipe of the nuclear power auxiliary water supply system, and the water outlet 105 of the silencer shell 10 is connected to the water outlet main pipe of the nuclear power auxiliary water supply system. The sealing pipe 702 of the sealing mechanism 70 is in an open state, and water flows in from the water inlet pipe 303 of the silencer chamber 301 and flows out from the water outlet pipe 304 of the silencer chamber 301. Combined with the effect of the sound-absorbing sleeve 80, the sound of the water flow can be reduced; after the silencer mechanism 30 in the silencer shell 10 has been used for a long time, the water outlet pipe 304 of the silencer chamber 301 is closed first, and the opening and closing can be controlled by the corresponding valve, and then the silencer chamber 301 is rotated, and the transmission block 708 rotates with the silencer chamber 301, which can drive the transmission rod 707 to drive the ring gear 706 to rotate, and the gear 705 rotates with the ring gear 706, thereby rotating the rotating rod 704, and finally realizing the rotation of the movable baffle 703, so that the sealing pipe 702 is closed. The filter 602 is then pulled out of the water inlet pipe 303 to clean the impurities on the filter 602 and prevent the filter 602 from being blocked by impurities. Finally, the handle 402 is pushed and pulled to drive the movable rod 401 to move, thereby driving the water removal component 50 to move in the soundproofing area 102. The adsorption net 502 of the water removal component 50 can absorb the water stains in the soundproofing area 102. In addition, the heating coil 503 can be turned on by the corresponding control switch to evaporate the residual water stains in the soundproofing area 102.

[0053] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
