[0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete basically unchanged. Most of them are anionic surfactants, such as lignin sulfonate, naphthalene sulfonate formaldehyde polymer, etc. After being added to the concrete mixture, it has a dispersing effect on cement particles, which can improve its workability, reduce unit water consumption or unit cement consumption, and save cement. The commonly used process flow is to first stir the TPEG solution evenly and keep its temperature at 70°C, then add the acrylic acid solution and hydrogen peroxide solution in the high-level tank within 3 hours, and add the thioglycolic acid solution in the high-level tank within 3.5 hours. After the insulation reaction is completed for 3 hours, the temperature is lowered to 40°C to obtain the finished product. Therefore, the dripping process of the reaction axe in the synthesis process of the water reducer is very important.

[0039] In this embodiment, the motor 141 is a servo rotary motor, which drives the active wheel 142 arranged at the output end of the motor 141 to rotate, and drives the driven wheel 142 arranged at the upper end of the dripping component 13 to rotate.

[0040] As a preferred embodiment of the present embodiment, the dripping assembly 13 includes a dripping tube 131 arranged on the liquid inlet 12 and connected to the feeding pipe 31, at least one dripping branch 132 arranged on the dripping tube 131 and extending toward the side wall of the main body 11, a dripping port 133 arranged at the end of the dripping branch 132, and a drainage groove arranged on the inner wall of the dripping tube 131 and the dripping branch 132.

[0041] In this embodiment, the dripping component 13 includes a dripping tube 131 that passes through the liquid inlet 12 and is connected to the feeding pipe 31. The dripping tube 131 is preferably arranged at the center of the reactor body 11. A plurality of dripping branches 132 are vertically arranged on the dripping tube 131 and extend outward. The dripping port 133 is arranged at the end of the dripping branch 132 to realize the delivery of the monomer to multiple positions of the raw material for dripping.

[0042] Compared with the prior art, the technical solution described in this embodiment has the following advantages: the dual control of the constant pressure unit and the connecting unit ensures the stability of monomer addition, realizes precise addition, improves reaction efficiency and product quality, reduces reaction time and energy consumption, and avoids situations such as reaction runaway caused by too fast monomer addition.

[0043] Embodiment 2

[0044] The difference between this embodiment and the first embodiment is that an anti-blocking member is added, as shown in the attached Figure 6As shown, specifically as follows: the dripping component 13 also includes an anti-blocking component 134 arranged at the end of the dripping branch pipe 132 and used for closing / opening the dripping port 133; the end of the dripping branch pipe 132 is a closed end, and the anti-blocking component 134 includes a baffle 1341 arranged on the inner wall of the dripping branch pipe 132 close to the dripping port 133, and a sphere 1342 arranged on one side of the baffle 1341 and used for closing / opening the dripping port 133.

[0045] In this embodiment, the dripping port 133 is opened at the lower end of the dripping branch pipe 132. Since the dripping assembly 13 has both dripping and stirring functions, it is easy for the raw materials in the main body 11 to flow back into the dripping port 133, which causes pollution to the device and affects the dripping efficiency. Therefore, an anti-blocking member 134 is provided at a position of the dripping branch pipe 132 near the dripping port 133; a baffle 1341 is provided on the side of the dripping port 133 near the dripping tube 131 to prevent the ball 1342 from rolling in the direction of the dripping tube 131. 342 is arranged on the dripping port 133. In the initial state, the dripping port 133 is closed to prevent the raw materials from being poured into the dripping assembly and causing blockage. When the device is turned on, the dripping tube 131 starts to rotate, and the ball 1342 rolls away from the dripping tube 131 under the action of centrifugal force. The end of the closed dripping branch pipe 132 controls the rolling of the ball to prevent it from falling out of the pipe. At this time, the dripping port 133 is opened, and the monomer is smoothly dripped into the raw materials of the reactor. Similarly, when the device is closed and stops rotating, the ball naturally falls back to the dripping port 133 to close the dripping port 133.

[0046] As a preferred embodiment of this embodiment, the anti-blocking member 134 further includes a water leakage hole 1343 arranged on the baffle 1341 and a filter screen arranged on the dripping port 133 .

[0047] In this embodiment, in order to prevent the baffle 1341 from causing too much obstruction to the monomer dripping, a plurality of water leakage holes 1343 are opened on the baffle 1341 so that the monomer can pass through the baffle smoothly, and a filter screen can also be set at the dripping port 133 to further prevent the inflow of external raw materials.

[0048] As a preferred embodiment of this embodiment, the bottom surface of the end of the dripping branch pipe 132 is a curved surface.

[0049] In this embodiment, the bottom surface of the end of the dripping branch 132 is a curved surface inclined upward, so that the ball 1342 can naturally and quickly fall back to the dripping port 133 after the device is closed, guiding the rolling trajectory of the ball.

[0050] Compared with the prior art, the technical solution described in this embodiment has the advantages of: avoiding the situation where the raw materials in the reactor flow back into the dropping device and causing blockage, effectively ensuring the stable operation of the dropping device, and reducing the negative impact of stirring on the dropping function.

[0051] Embodiment 3

[0052] The difference between this embodiment and the first and second embodiments is that a blocking member is added. Figure 7 As shown, the details are as follows: the dripping assembly 13 also includes a through groove 135 arranged at the end of the dripping branch pipe 132 and a blocking member 136 arranged in the through groove 135 .

[0053] In this embodiment, a through groove 135 is opened at the end of the drip branch pipe 132 near the anti-blocking part. The through groove 135 is convenient for later manual maintenance of the anti-blocking part. When extreme situations occur, or the filter screen, ball, etc. need to be replaced, the operator pulls out the blocking part 136 and processes it through the through groove 135; the blocking part 136 is set in the through groove 135, and under normal circumstances, the through groove 135 is closed to prevent the influence of external raw materials. The blocking part 136 can be set as an elastic plug.

[0054] As a preferred embodiment of the present embodiment, the blocking member 136 includes two blocking blocks 1361 arranged opposite to each other, an elastic block 1362 arranged between the two blocking blocks 1361, an insertion rod 1363 arranged on the side of the blocking block 1361 away from the elastic block 1362, a socket 1364 arranged on the side wall of the through groove 135 and used for inserting the insertion rod 1363, and a handle 1365 arranged at the upper end of the blocking block 1361.

[0055] In this embodiment, a specific structure of a blocking member 136 is disclosed; it includes two rigid blocking blocks 1361, by pinching the handles on the two blocking blocks 1361 to bring the two blocking blocks 1361 closer to each other, the insertion rod 1363 and the insertion hole 1364 are connected / separated, and the two blocking blocks 1361 are connected by an elastic block 1362. The elastic block is a rubber block, which is used to close the through slot and provide a certain deformation range.

[0056] Compared with the prior art, the technical solution described in this embodiment has the advantages of being more conducive to the later maintenance of the device and being able to effectively deal with device failure in extreme situations.

[0057] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
