When the helium passes through the gaps in the adsorbent, it absorbs the moisture in the helium.

[0003] However, when the adsorbent absorbs moisture in helium, the moisture content in the adsorbent will gradually increase, and its ability to absorb moisture will decrease, so that the adsorbent inside the device needs to be constantly replaced, which is very inconvenient to operate and greatly reduces the storage efficiency.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-Figure 4 A helium purification device for an optical fiber cooling tube comprises a housing 1, an air inlet pipe and an air outlet pipe are respectively installed at both ends of the housing 1, a fixing block 2 is fixedly installed in the housing 1, and a circular hole is opened on the surface of the fixing block 2;

[0022] A rotating slot is provided on the lower surface of the shell 1, one end of the rotating slot extends to a circular hole provided on the fixed block 2, a rotating rod 3 is rotatably installed on the lower surface of the shell 1 through a supporting block, a rotating disk 4 is fixedly sleeved on the rotating rod 3, the rotating disk 4 is rotatably inserted in the rotating slot, mounting holes are symmetrically provided on the rotating disk 4, adsorption cotton 5 is fixedly installed in both mounting holes, and a dryer 6 is fixedly installed on the lower surface of the shell 1 through a mounting block.

[0023] The adsorption cotton 5 can absorb moisture in the helium. When the helium enters the housing 1, it passes through the adsorption cotton 5 located in the circular hole, thereby absorbing moisture in the helium.

[0024] When the moisture in the adsorbent cotton 5 is too much, the transmission component will drive the rotating rod 3 to rotate 90°, thereby driving the adsorbent cotton 5 in the circular hole to rotate to the lower end of the rotating disk 4, and the adsorbent cotton 5 at the lower end will rotate into the circular hole to absorb moisture in the helium. After the adsorbent cotton 5 that absorbs moisture rotates 90° with the rotating disk 4, it just moves to the dryer 6 (the dryer 6 is the prior art and will not be introduced in detail here). The dryer 6 can dry the adsorbent cotton 5, thereby removing the moisture in the adsorbent cotton 5 so that the adsorbent cotton 5 can continue to be used. By rotating the rotating disk 4, the alternating operation of the two adsorbent cottons 5 is realized, and there is no need to constantly replace the adsorbent inside the device. The operation is simple and the helium purification efficiency is effectively improved.

[0025] A plurality of spiral rods 7 are fixedly installed in the middle part of the rotating rod 3, and the number of spiral turns of the spiral rod 7 is half a turn. A moving block 8 is horizontally slidably installed on the rotating rod 3, and four positioning grooves are opened on the moving block 8, and the plurality of positioning grooves correspond to the plurality of spiral rods 7 respectively. A transmission assembly for driving the moving block 8 to move back and forth is provided on the housing 1, and the transmission assembly includes a driving motor 9 fixedly installed on the housing 1 and a reciprocating screw 10 rotatably installed on two supporting blocks. The moving block 8 is threadedly sleeved on the reciprocating screw 10, and one end of the output shaft of the driving motor 9 is fixedly connected to one end of the reciprocating screw 10;

[0026] By starting the driving motor 9 to drive the reciprocating screw 10 to rotate, the reciprocating screw 10 drives the moving block 8 to move horizontally on the rotating rod 3. When the moving block 8 is about to move to the middle part of the rotating rod 3, the moving block 8 will contact the multiple screw rods 7, and one end of the multiple screw rods 7 will be inserted into the multiple positioning grooves respectively. Since the number of spiral turns of the screw rod 7 is half a turn, under the limitation of the screw rod 7, the rotating rod 3 will be driven to rotate half a turn, and then the rotating disk 4 will be driven to rotate half a turn through the rotating rod 3.

[0027] A rotating hole is provided on one of the support blocks, and a rotating shaft 11 is rotatably installed in the rotating hole. A fan blade 12 is fixedly installed at one end of the rotating shaft 11, and the fan blade 12 faces away from the dryer 6. A linkage assembly for driving the rotating shaft 11 to rotate is provided on the reciprocating screw rod 10. The linkage assembly includes a first transmission wheel 13 fixedly sleeved on the reciprocating screw rod 10, a second transmission wheel 14 fixedly sleeved on the rotating shaft 11, and a transmission belt 15, and the transmission belt 15 is sleeved on the first transmission wheel 13 and the second transmission wheel 14;

[0028] When the reciprocating screw 10 rotates, it will drive the first transmission wheel 13 to rotate, and then drive the second transmission wheel 14 to rotate through the transmission belt 15, thereby driving the rotating shaft 11 to rotate. During the rotation of the rotating shaft 11, the fan blades 12 will be driven to rotate, and the fan blades 12 are facing away from the dryer 6, thereby driving the hot air generated by the dryer 6 to pass through the adsorption cotton 5, accelerating the drying of the adsorption cotton 5.

[0029] A sealing gasket is fixedly installed on the inner wall of the rotating slot. The sealing gasket is made of rubber. The sealing gasket can reduce the gap between the rotating slot and the rotating disk 4, thereby preventing the helium in the housing 1 from leaking.

[0030] In the utility model, when the moisture in the adsorbent cotton 5 is too much, the transmission component will mobilize the rotating rod 3 to rotate 90°, thereby driving the adsorbent cotton 5 in the circular hole to rotate to the lower end of the rotating disk 4, and the adsorbent cotton 5 at the lower end will rotate into the circular hole, and one of the adsorbent cottons 5 will just move to the dryer 6 to dry the adsorbent cotton 5. The alternating operation of the two adsorbent cottons 5 is achieved by rotating the rotating disk 4, without the need to constantly replace the adsorbent inside the device, the operation is simple, and the helium purification efficiency is effectively improved.

[0031] In general, in view of the technical problem that the adsorbent inside the device needs to be constantly replaced, the operation is very inconvenient, and the extraction efficiency is greatly reduced; a technical solution is adopted: through the mutual cooperation of the transmission component, the rotating rod 3 and the rotating disk 4, two adsorbent cottons 5 are designed to be used alternately; because the implementation process of the technical solution is: when the adsorbent cotton 5 absorbs too much water, the transmission component will mobilize the rotating rod 3 to rotate 90°, thereby driving the adsorbent cotton 5 in the circular hole to rotate to the lower end of the rotating disk 4, and the adsorbent cotton 5 at the lower end will rotate into the circular hole, and one of the adsorbent cottons 5 just moves to the dryer 6, which has the effect of drying the adsorbent cotton 5, and the alternating operation of the two adsorbent cottons 5 is realized by rotating the rotating disk 4; so the technical problem can definitely be solved, and the technical effect achieved is: there is no need to constantly replace the adsorbent inside the device, the operation is simple, and the helium purification efficiency is effectively improved.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
