[0021] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present utility model.

[0022] Example 1

[0023] Please refer to Figures 1 - 4 , the present utility model provides a technical solution: a neutralization device for water reducer production, including: a neutralization barrel 1, a barrel cover 2 is arranged at the top of the neutralization barrel 1, a rotating shaft 3 is rotatably connected to the surface of the barrel cover 2, a stirring plate 4 is fixed on the shaft body of the rotating shaft 3, a slot 5 is opened on the surface of the stirring plate 4, a plug-in plate 7 is movably inserted into the slot 5, one end of the plug-in plate 7 extending out of the slot 5 is fixed with a scraping plate 13, and the other end of the scraping plate 13 abuts against the inner wall of the neutralization barrel 1.

[0024] During actual use, when neutralizing the water reducer in the neutralization barrel 1, the plug-in plate 7 and the scraping plate 13 are not arranged on the surface of the stirring plate 4. After the water reducer in the neutralization barrel 1 is neutralized and discharged from the drain port at the bottom of the neutralization barrel 1, the barrel cover 2 is removed from the neutralization barrel 1, and then the plug-in plate 7 is inserted into the slot 5, so as to install the scraping plate 13 on the stirring plate 4. Then the barrel cover 2 is reinstalled on the neutralization barrel 1, and the motor arranged at the top of the barrel cover 2 is operated at a low speed gear. The motor drives the rotating shaft 3 to rotate slowly, and the rotating shaft 3 drives the scraping plate 13 to rotate slowly through the stirring plate 4. The scraping plate 13 scrapes across the inner wall of the neutralization barrel 1, scraping off the water reducer adhered to the inner wall of the neutralization barrel 1. The scraped water reducer flows downward along the scraping plate 13 and is discharged from the drain port at the bottom of the neutralization barrel 1, so that the water reducer adhered to the inner wall of the neutralization barrel 1 can be collected and utilized, reducing waste, and at the same time reducing the cleaning difficulty of the neutralization barrel 1.

[0025] Example 2

[0026] On the basis of Example 1, in order to limit and contact-limit the plug-in plate 7 after the plug-in plate 7 is inserted into the slot 5, a limiting rod installation groove 8 is opened on the surface of the plug-in plate 7, a limiting groove 11 is opened on the surface of the stirring plate 4, one end of a limiting rod 10 is movably inserted into the limiting rod installation groove 8, the other end of the limiting rod 10 is movably inserted into the limiting groove 11, a second spring 9 is fixed at the end of the limiting rod 10 extending into the limiting rod installation groove 8, the other end of the second spring 9 is fixed on the surface of the limiting rod installation groove 8, a push rod 12 is movably inserted into the limiting groove 11, the push rod 12 is in the shape of a "work" shaped rod structure, and one end of the push rod 12 extends out from the top of the stirring plate 4.

[0027] When inserting the plug-in board 7 into the slot 5, first press the limit rod 10 completely into the limit rod installation groove 8, so that the second spring 9 is compressed. When the plug-in board 7 is inserted into the slot 5 and the limit rod installation groove 8 is aligned with the limit groove 11, the second spring 9 generates a push on the limit rod 10 under its own elastic force, pushing one end of the limit rod 10 into the limit groove 11, while the other end of the limit rod 10 remains in the limit rod installation groove 8, thus limiting the plug-in board 7 in the slot 5. When it is necessary to remove the plug-in board 7 from the slot 5, press down the push rod 12, and the push rod 12 pushes the end of the limit rod 10 inserted into the limit groove 11 out of the limit groove 11, so that the limit rod 10 is completely retracted into the limit rod installation groove 8 again, and the limit of the plug-in board 7 can be released.

[0028] Embodiment III

[0029] On the basis of Embodiment II, in order to prevent the water reducing agent from entering the slot 5 during the neutralization of the water reducing agent, a sealing plate 16 is slidably connected in the slot 5. One end of the sealing plate 16 is fixed with a first spring 6, and the other end of the first spring 6 is fixed on the inner wall of the slot 5. A guide groove 14 is formed on the inner wall of the slot 5, and a slider 15 is fixed on the surface of the sealing plate 16. The slider 15 is slidably connected in the guide groove 14.

[0030] When neutralizing the water reducing agent in the neutralization barrel 1, the plug-in board 7 is not arranged in the slot 5. The first spring 6 generates a thrust on the sealing plate 16 under its own elastic force, causing the sealing plate 16 to move outward. When the sealing plate 16 moves outward, the slider 15 also moves in the same direction in the guide groove 14. After one end of the slider 15 abuts against the inner wall of the guide groove 14, the sealing plate 16 can be prevented from continuing to move outward, thereby preventing the sealing plate 16 from being disengaged from the slot 5, so that the sealing plate 16 seals the opening of the slot 5 and prevents the water reducing agent in the neutralization barrel 1 from entering the slot 5.

[0031] In actual use, when neutralizing the water reducing agent in the neutralizing barrel 1, the insertion plate 7 and the scraping plate 13 are not arranged on the surface of the stirring plate 4. After the water reducing agent in the neutralizing barrel 1 is neutralized and discharged from the drain port at the bottom of the neutralizing barrel 1, the barrel cover 2 is removed from the neutralizing barrel 1, and then the insertion plate 7 is inserted into the slot 5, so as to install the scraping plate 13 on the stirring plate 4. Then the barrel cover 2 is reinstalled on the neutralizing barrel 1, and the motor provided at the top end of the barrel cover 2 is operated at a low speed gear. The motor drives the rotating shaft 3 to rotate slowly, and the rotating shaft 3 drives the scraping plate 13 to rotate slowly through the stirring plate 4. The scraping plate 13 scrapes across the inner wall of the neutralizing barrel 1, scraping off the water reducing agent adhering to the inner wall of the neutralizing barrel 1 from the inner wall of the neutralizing barrel 1. The scraped water reducing agent flows downward along the scraping plate 13 and is discharged from the drain port at the bottom of the neutralizing barrel 1, so that the water reducing agent adhering to the inner wall of the neutralizing barrel 1 can be collected and utilized, reducing waste and also reducing the cleaning difficulty of the neutralizing barrel 1; when inserting the insertion plate 7 into the slot 5, first press the limiting rod 10 completely into the limiting rod installation groove 8, so that the second spring 9 is compressed. When the insertion plate 7 is inserted into the slot 5 and the limiting rod installation groove 8 is aligned with the limiting groove 11, the second spring 9 generates a push on the limiting rod 10 under its own elastic force, pushing one end of the limiting rod 10 into the limiting groove 11, and the other end of the limiting rod 10 still remains in the limiting rod installation groove 8, so as to limit the insertion plate 7 in the slot 5; when it is necessary to remove the insertion plate 7 from the slot 5, press down the push rod 12, and the push rod 12 pushes the end of the limiting rod 10 inserted into the limiting groove 11 out of the limiting groove 11, so that the limiting rod 10 is completely retracted into the limiting rod installation groove 8 again, and the limitation of the insertion plate 7 can be released; when neutralizing the water reducing agent in the neutralizing barrel 1, the insertion plate 7 is not arranged in the slot 5. The first spring 6 generates a thrust on the sealing plate 16 under its own elastic force, causing the sealing plate 16 to move outward. When the sealing plate 16 moves outward, the slider 15 also moves in the same direction in the guide groove 14. After one end of the slider 15 abuts against the inner wall of the guide groove 14, the sealing plate 16 can be prevented from continuing to move outward, thereby preventing the sealing plate 16 from disengaging from the slot 5, so that the sealing plate 16 seals the opening of the slot 5 and prevents the water reducing agent in the neutralizing barrel 1 from entering the slot 5.
