Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-5 , a sampling device for wet strength agent detection, including a storage barrel 1, a cover plate 2 is slidably installed above the storage barrel 1, a toothed ring 3 is fixedly installed on the inner wall of the storage barrel 1, an extraction pipe 4 is rotatably penetrated and installed at the bottom of the cover plate 2, a plurality of through holes connected to the inside are opened on the outer wall of the extraction pipe 4, two stirring shafts 6 are rotatably installed on the outer wall of the extraction pipe 4 through a connecting plate 5, two gears 7 are fixedly installed on the outer walls of the two stirring shafts 6, and the two gears 7 are engaged with the toothed ring 3. A plurality of stirring blades 9 are fixedly installed on the two stirring shafts 6 through a connecting mechanism. The connecting mechanism includes a connecting sleeve 8 fixedly installed on the outer wall of the stirring shaft 6, and each stirring blade 9 is fixedly installed on the outer wall of the connecting sleeve 8.

[0023] A first motor 11 is fixedly installed on the upper end surface of the cover plate 2 through a support mechanism. The support mechanism includes a support plate 10 fixedly installed on the upper end surface of the cover plate 2, and the first motor 11 is fixedly installed on the upper end surface of the support plate 10. The outer wall of the output shaft of the first motor 11 is connected to the extraction pipe 4 through a transmission mechanism. The transmission mechanism includes belt pulleys 12 fixedly installed on the outer walls of the extraction pipe 4 and the output shaft of the first motor 11, and the two belt pulleys 12 are connected and driven by a belt. The support plate 10 is L-shaped, and there is a certain gap between its bottom wall and the upper end surface of the cover plate 2, and this gap can provide a space for the belt to rotate.

[0024] A lifting frame 13 is fixedly installed on the upper end surface of the cover plate 2. A screw rod 14 is rotatably installed inside the lifting frame 13. A second motor 15 connected to the screw rod 14 is fixedly installed on the upper end surface of the lifting frame 13. A moving block 17 is threadedly installed on the outer wall of the screw rod 14 through a limiting mechanism. The limiting mechanism includes a limiting rod 16 installed and fixed inside the lifting frame 13. The limiting rod 16 slidably penetrates through the moving block 17. The limiting rod 16 can play a limiting role on the moving block 17, so that the moving block 17 can only axially move along the outer wall of the screw rod 14, thereby realizing the vertical up and down movement of the sampling pump 19. The outer wall of the moving block 17 is fixedly connected to the sampling pump 19 through a connecting mechanism.

When storing, the upper end surface of the storage barrel 1 can be covered by the cover plate 2, so as to ensure the sealing performance of the storage barrel 1 and prevent the wet strength agent inside from being contaminated. When precipitation crystallization occurs during the static state of the wet strength agent, the first motor 11 is started, and the outer wall of its output shaft drives the extraction pipe 4 to rotate through two belt pulleys 12 connected by a belt. The extraction pipe 4 drives the connection plate 5 to rotate, and the connection plate 5 can drive the two stirring shafts 6 to rotate inside the storage barrel 1. At this time, the two stirring shafts 6 can drive the gears 7 to engage with the toothed ring 3, so that the two stirring shafts 6 can rotate at high speed on the connection plate 5. And the two stirring shafts 6 can respectively drive multiple stirring blades 9 on the same side to rotate at high speed through the connecting sleeves 8. Through the rotation and stirring of the multiple stirring blades 9, the precipitation crystallization of the wet strength agent during the static state can be stirred to mix it with the liquid, preventing detection errors caused by precipitation;

When the screw 14 rotates, it can drive the moving block 17 to move up and down through the cooperation with the limiting rod 16. The moving block 17 then drives the sampling pump 19 to move up and down through the cooperation of the connecting rod 18. When the sampling pump 19 moves up and down, it will also drive its inlet pipe to move up and down inside the extraction pipe 4. Through the cooperation of multiple through holes opened on the outer wall of the extraction pipe 4, the sampling pump 19 can extract the wet strength agent at different heights inside the storage barrel 1 through its inlet pipe.
