[0017] The accompanying drawings are specific embodiments of the present utility model.

[0018] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0020] like Figures 1 to 4 As shown, the constant drop device for producing raw materials for sulfonate copolymer cement grinding aids includes a material tank 1, which is used to hold formaldehyde solution. A discharge pipe 2 is installed at the lower end of the material tank 1, and a transverse pipe 4 is installed at the lower end of the discharge pipe 2. The lower end of the transverse pipe 4 is connected to a feed pipe 5, which is used to access the reaction system. A rotating shaft 6 is axially installed in the transverse pipe 4. The volume of the rotating shaft 6 is equivalent to the volume of the transverse pipe 4. A discharge hole 7 is opened on the rotating shaft 6, and the discharge hole 7 can connect the discharge pipe 2 and the feed pipe 5; after the transverse pipe 4 is extended from the center of the rotating shaft 6, a reduction motor 8 is connected to the rotating shaft 6, and the reduction motor 8 drives the rotating shaft 6 to rotate.

[0021] In order to make the addition of formaldehyde solution more uniform, several diversion pipes 3 are installed at the lower end of the feed pipe 2. The formaldehyde solution flowing out of the feed pipe 2 is diverted into the diversion pipe 3. There are also several feed pipes 2, the same number as the diversion pipes 3. There are also several feed holes 7, which are evenly distributed in a spiral shape and the same number as the diversion pipes 3. That is to say, during the rotation of the rotating shaft 6, only one feed hole 7 can connect one group of diversion pipes 3 and the feed pipe 5 at a time.

[0022] In order to extend the addition time of the formaldehyde solution each time, the feeding hole 7 can be set to be long and narrow, with the length direction being the circumferential direction of the rotating shaft 6 .

[0023] In order to facilitate installation, a connecting pipe 9 is also connected to the transverse pipe 4, and the lower end of the connecting pipe 9 is a connecting flange 10 for connection to the flange on the reaction system; all feed pipes 5 are located in the connecting pipe 9; at this time, the distance between the outer sides of the two feed pipes 5 located on the outside is equivalent to the diameter of the transverse pipe 4.

[0024] When in use, start the reduction motor 8, and the reduction motor 8 drives the rotating shaft 6 to rotate. However, when one of the discharge holes 7 is rotated to connect its corresponding branch pipe 3 and the feed pipe 5, the formaldehyde solution flows from the discharge hole 7 into the corresponding feed pipe 5, and then enters the reaction system until the discharge hole 7 leaves the branch pipe 3 and the feed pipe 5, cutting off the connection between the two. The rotating shaft 6 continues to rotate to the next discharge hole 7 to connect its corresponding branch pipe 3 and the feed pipe 5, and continues to add formaldehyde solution. This cycle continues, so that the formaldehyde solution is added at a uniform rate.
