[0021] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0022] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model provides a technical solution: a disodium dihydrogen pyrophosphate polymerization device, comprising a device tank 1, a feed port 2 is installed on the top of the device tank 1, a discharge port 3 is installed on the bottom of the device tank 1, a moving groove 4 is opened on the top of the device tank 1, a moving rod 5 is slidably connected inside the moving groove 4, a pull plate 6 is fixedly connected to the top of the moving rod 5, a circular plate 7 is fixedly connected to the bottom of the moving rod 5, a scraper 8 is installed around the circular plate 7, a first hollow box 9 is fixedly connected to the bottom of the pull plate 6, a fixed block 10 is fixedly connected to the front end of the device tank 1, a limiting groove 11 is opened at the front end of the fixed block 10, a connecting block 12 is slidably connected inside the limiting groove 11, and a second hollow box 13 is fixedly connected to the front end of the connecting block 12. The staff pulls the moving rod 5 up and down to make the moving rod 5 drive the circular plate 7 and the scraper 8 installed at the bottom to move inside the device tank 1, and the scraper 8 can remove the disodium dihydrogen pyrophosphate attached to the inner wall of the device tank 1 in real time to prevent it from forming agglomerates or deposits, thereby ensuring the uniformity and efficiency of the polymerization reaction.

[0023] Reference Figure 2 and Figure 4 As shown, in the present embodiment: round holes 14 are provided on both sides of the second hollow box 13, a round rod 15 is slidably connected inside the round hole 14, an L-shaped clamping plate 16 is fixedly connected to the left side of the round rod 15, and clamping grooves 17 are provided on both sides of the first hollow box 9. When the staff does not use the scraper 8, the second hollow box 13 can be moved upwards, and then the round rod 15 is pressed inwards to drive the L-shaped clamping plate 16, so that the L-shaped clamping plate 16 is inserted into the interior of the first hollow box 9 to limit and fix the position of the moving rod 5.

[0024] Reference Figure 4 As shown, in this embodiment: the second hollow box 13 is internally fixedly connected with a limiting rod 18, and a limiting hole 19 is opened on one side of the L-shaped clip plate 16. By setting the limiting rod 18 and the limiting hole 19, the moving trajectory of the L-shaped clip plate 16 can be limited to prevent the L-shaped clip plate 16 from shifting or shaking during the movement, thereby ensuring that the L-shaped clip plate 16 can be accurately clipped into the clip groove 17.

[0025] Reference Figure 4As shown, in this embodiment: a reset spring 20 is fixedly connected to the left side of the L-shaped clamping plate 16. By setting the reset spring 20, the reset spring 20 can quickly reset the L-shaped clamping plate 16 through its own elastic force, making it faster for the staff to fix it.

[0026] Reference Figure 5 As shown, in this embodiment: slide grooves 21 are provided on both sides of the limit groove 11, and sliders 22 are fixedly connected on both sides of the connecting block 12. By setting the slide grooves 21 and the sliders 22, the connecting block 12 and the second hollow box 13 form a stable motion trajectory when moving up and down, and there will be no shaking or falling off.

[0027] Reference Figure 4 As shown, in the present embodiment: the outer shape of the L-shaped clip plate 16 matches the inner shape of the clip groove 17. When the outer shape of the L-shaped clip plate 16 matches the inner shape of the clip groove 17, the L-shaped clip plate 16 can be accurately inserted into the interior of the clip groove 17, thereby making it more stable for the staff to fix the first hollow box 9 and the second hollow box 13.

[0028] Reference Figure 6 As shown, in the present embodiment: a plurality of movable holes 23 are opened around the circular plate 7, a thrust spring 24 is fixedly connected to the rear end of the inner cavity of the movable hole 23, and a front end of the thrust spring 24 is fixedly connected to the inner wall of the scraper 8. By installing the thrust spring 24 around the circular plate 7, the scraper 8 can always fit tightly with the inner wall of the device tank 1, thereby improving the cleaning effect of the scraper 8.

[0029] The working principle of the utility model is as follows: the staff pulls the moving rod 5 up and down, so that the moving rod 5 drives the circular plate 7 and the scraper 8 installed at the bottom to move inside the device tank 1. The scraper 8 can remove the disodium dihydrogen pyrophosphate attached to the inner wall of the device tank 1 in real time to prevent it from forming lumps or deposits, thereby ensuring the uniformity and efficiency of the polymerization reaction. When the staff does not use the scraper 8, they can move the second hollow box 13 upwards, and then drive the L-shaped clamping plate 16 by pressing the round rod 15 inwards, so that the L-shaped clamping plate 16 is inserted into the first hollow box 9 to limit and fix the position of the moving rod 5. By setting the limiting rod 18 and the limiting hole 19, the moving trajectory of the L-shaped clamping plate 16 can be limited to prevent the L-shaped clamping plate 16 from deflecting or shaking during the movement, thereby ensuring that the L-shaped clamping plate 1 6 can be accurately inserted into the clamping groove 17. By setting the reset spring 20, the reset spring 20 can quickly reset the L-shaped clamping plate 16 through its own elastic force, so that the staff can fix it more quickly. By setting the slide groove 21 and the slider 22, the connecting block 12 and the second hollow box 13 form a stable movement trajectory when moving up and down, and there will be no shaking or falling off. When the external shape of the L-shaped clamping plate 16 coincides with the internal shape of the clamping groove 17, the L-shaped clamping plate 16 can be accurately inserted into the inside of the clamping groove 17, so that the staff can fix the first hollow box 9 and the second hollow box 13 more firmly. By installing thrust springs 24 around the circular plate 7, the scraper 8 can always fit closely with the inner wall of the device tank 1, thereby improving the cleaning effect of the scraper 8.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
