[0062] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0063] The water-reducing agent synthesis apparatus of the present invention is described below with reference to the accompanying drawings.

[0064] like Figure 1 As shown, the present invention provides a water-reducing agent synthesis device, which includes a reaction device 10, a first liquid inlet device 20, and a water supply device 30. The reaction device 10 includes a reaction stirring tank 11 and a reaction stirring mechanism 12. The upper end of the reaction stirring tank 11 is provided with a first liquid inlet 111, a water inlet 112, and a solid material loading port 113, and the lower end of the reaction stirring tank 11 is provided with a discharge port. The reaction stirring mechanism 12 is disposed inside the reaction stirring tank 11. The first liquid inlet device 20 includes a liquid inlet stirring tank 21 and a liquid inlet assembly. The liquid inlet stirring tank 21 is used to hold the water-reducing agent synthesis liquid. The liquid inlet assembly includes a first liquid inlet pipe 22 and a pipeline pump 23. The two ends of the first liquid inlet pipe 22 are respectively connected to the liquid inlet stirring tank 21 and the first liquid inlet 111. The pipeline pump 23 is disposed on the first liquid inlet pipe 22. The water supply device 30 is used to supply water to the water inlet 112 and the liquid inlet stirring tank 21 respectively.

[0065] Specifically, the liquid inlet mixing tank 21 is connected to the first liquid inlet 111 on the reaction mixing tank 11 through the first liquid inlet pipe 22. The first liquid inlet pipe 22 is equipped with a pipeline pump 23. The liquid inlet mixing tank 21 contains a water-reducing agent synthesis liquid for preparing the water-reducing agent. The pipeline pump 23 is used to pump the water-reducing agent synthesis liquid in the liquid inlet mixing tank 21 into the reaction mixing tank 11 through the first liquid inlet pipe 22. The water supply device 30 is used to supply water into the reaction mixing tank 11 through the water inlet 112 on the reaction mixing tank 11. The solid material filling port 113 on the reaction mixing tank 11 is used to add solid material for preparing the water-reducing agent into the reaction mixing tank 11. When the solid material, the water-reducing agent synthesis liquid, and water and other materials for preparing the water-reducing agent are added into the reaction mixing tank 11, the reaction stirring mechanism 12 in the reaction mixing tank 11 operates and stirs the materials to prepare the water-reducing agent. In the water-reducing agent synthesis equipment, the reaction device 10, the first liquid inlet device 20, and the water supply device 30 are small in size and occupy little space, which allows the reaction mixing tank 11 and the liquid inlet mixing tank 21 to be directly assembled onto the transport vehicle and transported to the work site for on-site preparation of water-reducing agent. This allows for flexible adjustment of the dosage of water-reducing agent synthesis liquid, solid material, and water and other preparation materials according to the actual needs of concrete mixing, thereby improving the concrete mixing effect and effectively preventing the water-reducing agent from volatilizing or deteriorating during storage and transportation, thus ensuring the preparation quality of the water-reducing agent.

[0066] Furthermore, such as Figure 2 and Figure 3 As shown, the water-reducing agent synthesis equipment also includes a skid-mounted container 50. The reaction device 10, the first liquid inlet device 20, and the water supply device 30 are installed inside the skid-mounted container 50. By mounting the skid-mounted container 50 on a transport vehicle, the water-reducing agent synthesis equipment can be transported to the work site for on-site preparation of the water-reducing agent, improving the quality of the water-reducing agent preparation and reducing resource waste. Furthermore, the water-reducing agent synthesis liquid is pumped by a pipeline pump 23. The pipeline pump 23 has high flow rate adjustment precision to accurately control the delivery volume of the water-reducing agent synthesis liquid, further improving the preparation quality.

[0067] In this embodiment of the invention, the water-reducing agent synthesis equipment further includes a second liquid inlet device 40, which includes a second liquid inlet pipe 41, an additive flow meter 42, and a liquid inlet pump 43. The upper end of the reaction stirring tank 11 is also provided with a second liquid inlet 114. The second liquid inlet pipe 41 is connected to the second liquid inlet 114 and is used to supply water-reducing agent additive liquid into the reaction stirring tank 11. The additive flow meter 42 and the liquid inlet pump 43 are both provided on the second liquid inlet pipe 41.

[0068] like Figure 1As shown, during the preparation of the water-reducing agent, it is also necessary to add water-reducing agent additive liquid into the reaction stirring tank 11. The second liquid inlet pipe 41 is connected to the second liquid inlet 114 on the reaction stirring tank 11, so that the liquid inlet pump 43 can pump the water-reducing agent additive liquid into the reaction stirring tank 11 through the second liquid inlet pipe 41, thereby improving the preparation efficiency of the water-reducing agent. In addition, the second liquid inlet pipe 41 is equipped with an additive liquid flow meter 42, which can detect the flow rate of the water-reducing agent additive liquid in the second liquid inlet pipe 41, so as to accurately control the delivery amount of the water-reducing agent additive liquid, further improving the preparation effect of the water-reducing agent.

[0069] In embodiments of the present invention, such as Figure 1 and Figure 8 As shown, the reaction apparatus 10 also includes a first weighing scale 13 and a controller 14. The reaction stirring tank 11 is mounted on the first weighing scale 13, which is used to weigh the reaction stirring tank 11. The controller 14 is communicatively connected to the first weighing scale 13, the water supply device 30, the liquid inlet pump 43, the reaction stirring mechanism 12, and the pipeline pump 23. Figure 9 The diagram illustrates a synthesis method for water-reducing agent synthesis using a water-reducing agent synthesis equipment. Specifically, the controller 14 is configured as follows:

[0070] Step S10: When the weight of the reaction stirring tank 11 is determined to be the first preset weight, control the water supply device 30 to supply water to the water inlet 112.

[0071] Specifically, during the synthesis of the water-reducing agent, the solid material is first added into the reaction mixing tank 11 through the solid material filling port 113. The first weighing scale 13 weighs the reaction mixing tank 11. If the weight of the reaction mixing tank 11 exceeds the first preset weight, it can be determined that the solid material filling is complete. When the solid material filling is complete, the controller 14 controls the water supply device 30 to supply water into the reaction mixing tank 11 through the water inlet 112.

[0072] Step S20: When the weight of the reaction stirring tank 11 is determined to be the second preset weight, control the water supply device 30 to stop supplying water and control the liquid inlet pump 43 to run.

[0073] Specifically, the first weighing scale 13 weighs the reaction mixing tank 11 during the water supply process. If the weight of the reaction mixing tank 11 exceeds the second preset weight, it can be determined that the water supply meets the standard. When the water supply meets the standard, the controller 14 controls the water supply device 30 to stop and controls the liquid inlet pump 43 to run, so that the liquid inlet pump 43 pumps the water-reducing agent additive liquid into the reaction mixing tank 11 through the second liquid inlet pipe 41.

[0074] Step S30: When the weight of the reaction stirring tank 11 is determined to be the third preset weight, control the liquid inlet pump 43 to stop running and control the reaction stirring mechanism 12 to run.

[0075] Specifically, the first weighing scale 13 weighs the reaction mixing tank 11 during the pumping of the water-reducing agent additive liquid. If the weight of the reaction mixing tank 11 exceeds the third preset weight, it can be determined that the water-reducing agent additive liquid delivery volume meets the standard. When the water-reducing agent additive liquid delivery volume meets the standard, the controller 14 controls the liquid inlet pump 43 to stop running and controls the reaction stirring mechanism 12 to run, so that the reaction stirring mechanism 12 stirs the solid material, water and water-reducing agent additive liquid to complete the preparation of the water-reducing agent base liquid.

[0076] Step S40: Control the operation of pipeline pump 23 and adjust the flow rate of water-reducing agent synthesis liquid in the first inlet pipe 22 according to the preset liquid inlet duration and preset liquid inlet volume;

[0077] Specifically, the pipeline pump 23 is controlled to pump the water-reducing agent synthesis liquid in the inlet mixing tank 21 to the reaction mixing tank 11 through the first inlet pipe 22. The pumping speed of the pipeline pump 23 is adjusted according to the preset inlet time and preset inlet volume to deliver the preset inlet volume of water-reducing agent synthesis liquid to the reaction mixing tank 11 within the preset inlet time. The reaction mixing mechanism 12 continuously mixes the solid material, water, water-reducing agent additive liquid and water-reducing agent synthesis liquid to complete the preparation of the water-reducing agent. After the water-reducing agent is prepared, it can be discharged through the outlet of the reaction mixing tank 11 to be added to the concrete for mixing. This realizes the on-site preparation of the water-reducing agent and allows for flexible adjustment of the delivery volume of solid material, water, water-reducing agent additive liquid and water-reducing agent synthesis liquid according to the concrete mixing and on-site operation conditions, thereby improving the preparation quality.

[0078] Furthermore, such as Figure 1 and Figure 4 As shown, the liquid inlet assembly also includes a synthetic liquid flow meter 26 installed on the first liquid inlet pipe 22. The synthetic liquid flow meter 26 can detect the flow rate of the water-reducing agent synthetic liquid in the first liquid inlet pipe 22, so as to accurately control the amount of water-reducing agent synthetic liquid delivered to the reaction stirring tank 11, and further improve the water-reducing agent preparation effect.

[0079] In this embodiment of the invention, the reaction stirring tank 11 includes a tank body 115, a double-layered insulation sleeve 116, and an inner liner 117. The inner liner 117 is located inside the tank body 115 and is open. The double-layered insulation sleeve 116 is located outside the inner liner 117 and sandwiched between the tank body 115 and the inner liner 117. The first liquid inlet 111, the second liquid inlet 114, the water inlet 112, and the solid material filling port 113 are all opened on the tank body 115. The discharge port is opened on the tank body 115 and the inner liner 117. The reaction stirring mechanism 12 is located in the inner liner 117.

[0080] like Figure 6 and Figure 7As shown, the inner liner 117 is used to hold solid materials, water, water-reducing agent additive liquid and water-reducing agent synthesis liquid for the preparation of water-reducing agent. The double-layer insulation sleeve 116 covers the outside of the inner liner 117 to play a role in heat preservation, providing heat preservation conditions for the preparation of water-reducing agent. In addition, both the double-layer insulation sleeve 116 and the inner liner 117 are black and inside the tank body 115. The tank body 115 plays a role in protecting the inner liner 117, which is convenient for assembly into the skid box 50 and improves transportation stability.

[0081] In this embodiment of the invention, the reaction device 10 further includes a heating assembly, which includes a heating rod 15, a heat-conducting ring tube 16, and a reaction temperature display instrument 17. The heating rod 15 is disposed inside the tank body 115 and passes through the double-layer insulation sleeve 116 and the inner liner 117. The heat-conducting ring tube 16 is arranged in a ring shape and disposed in the inner liner 117. The heating rod 15 is connected to the heat-conducting ring tube 16. The reaction temperature display instrument 17 is disposed outside the tank body 115 at a position corresponding to the heat-conducting ring tube 16.

[0082] like Figure 6 and Figure 7 As shown, the heating rod 15 is used to connect to the power supply to generate heat. The heat generated by the heating rod 15 can be conducted to the heat-conducting ring tube 16. The heat-conducting ring tube 16 is arranged in a ring and connected to the inner wall of the inner liner 117 to heat the preparation materials in the reaction stirring tank 11, which accelerates the preparation speed of the water-reducing agent. In addition, the outer wall of the tank 115 is equipped with a reaction temperature display instrument 17 to facilitate real-time observation and control of the preparation heating temperature, thereby improving the preparation quality of the water-reducing agent.

[0083] In this embodiment of the invention, the reaction stirring mechanism 12 includes a rotation drive 121 and a reaction stirring paddle 122. The rotation drive 121 is located at the upper end of the tank 115. The reaction stirring paddle 122 includes a rotating rod 1221, a first blade 1222, and a second blade 1223. The upper end of the rotating rod 1221 is drivenly connected to the rotation drive 121. The rotating rod 1221 passes through the tank 115 and extends into the inner liner 117. The first blade 1222 and the second blade 1223 are spaced apart on the rotating rod 1221, and the second blade 1223 is located between the first blade 1222 and the heat-conducting ring tube 16.

[0084] like Figure 6 and Figure 7 As shown, the rotating drive 121 drives the rotating rod 1221 to rotate, causing the rotating rod 1221 to drive the first blade 1222 and the second blade 1223 to swing and stir the solid material, water, water-reducing agent additive liquid and water-reducing agent synthetic liquid. The first blade 1222 is located above the second blade 1223. The first blade 1222 is used to mix the solid material, water, water-reducing agent additive liquid and water-reducing agent synthetic liquid evenly. The second blade 1223 is used to disperse the mixed preparation material so that the preparation material circulates in the reaction stirring tank 11, further improving the mixing uniformity and mixing efficiency.

[0085] In this embodiment of the invention, the reaction device 10 further includes a discharge assembly 18, which includes a discharge pipe 181, a discharge switch valve 182, and a discharge pump 183. The discharge pipe 181 is connected to a discharge port, and the discharge switch valve 182 and the discharge pump 183 are both located on the discharge pipe 181. Figure 1 As shown, solid materials, water, water-reducing agent additive liquid, and water-reducing agent synthesis liquid are stirred in the reaction mixing tank 11 to obtain water-reducing agent. After the water-reducing agent is prepared, the discharge pump 183 is controlled to run, so that the discharge pump 183 pumps the water-reducing agent in the reaction mixing tank 11 to the discharge pipe 181. The discharge switch valve 182 on the discharge pipe 181 is opened to realize the discharge of water-reducing agent. By connecting the discharge end of the discharge pipe 181 to the concrete mixing plant, the water-reducing agent is transported to the concrete mixing plant for concrete mixing, thereby improving the concrete mixing effect.

[0086] Furthermore, the discharge assembly 18 also includes a discharge regulating valve 184 and a return pipe 185. The discharge regulating valve 184 is located on the discharge pipe 181, and the discharge pump 183 is located between the discharge regulating valve 184 and the discharge switch valve 182. The discharge pipe 181 is provided with a detection sampling port and a return port. The detection sampling port is located between the discharge regulating valve 184 and the discharge pump 183, and the return port is located between the discharge pump 183 and the discharge switch valve 182. One end of the return pipe 185 is connected to the return port, and the other end of the return pipe 185 is connected to the reaction stirring tank 11.

[0087] like Figure 1 As shown, after the water-reducing agent is prepared, the discharge pump 183 is controlled to run, so that the discharge pump 183 pumps the water-reducing agent in the reaction mixing tank 11 to the discharge pipe 181. The flow rate of the water-reducing agent is controlled by adjusting the opening of the discharge regulating valve 184. A sampling box 186 is set at the sampling port. Before the water-reducing agent is discharged, it can be sampled through the sampling box 186. If it is determined that the water-reducing agent meets the requirements of concrete mixing, the discharge switch valve 182 is opened to realize the discharge of the water-reducing agent. If it is determined that the water-reducing agent does not meet the requirements of concrete mixing, the discharge switch valve 182 is kept closed, and the water-reducing agent is returned to the reaction mixing tank 11 through the return pipe 185 for reaction and preparation again, thus ensuring the quality of the water-reducing agent preparation.

[0088] In this embodiment of the invention, the first liquid inlet device 20 further includes a liquid supply component 24 and a mixing and stirring mechanism 25. The liquid supply component 24 includes a liquid supply pipe 241, a liquid supply flow meter 242 and a liquid supply pump 243. The liquid supply pipe 241 is connected to the liquid inlet stirring tank 21 and is used to supply the water-reducing agent synthesis liquid into the liquid inlet stirring tank 21. The liquid supply flow meter 242 and the liquid supply pump 243 are both provided on the liquid supply pipe 241. The mixing and stirring mechanism 25 is provided inside the liquid inlet stirring tank 21.

[0089] like Figure 4 As shown, before preparing the water-reducing agent, the water-reducing agent synthesis liquid needs to be mixed evenly with water. The liquid supply pipe 241 is connected to the liquid inlet mixing tank 21, so that the liquid supply pump 243 can pump the water-reducing agent synthesis liquid through the liquid supply pipe 241 into the liquid inlet mixing tank 21. The water supply device 30 supplies water to the liquid inlet mixing tank 21. The mixing and stirring mechanism 25 operates and stirs the water-reducing agent synthesis liquid and water, which improves the preparation efficiency of the water-reducing agent. In addition, the liquid supply pump 243 is equipped with a liquid supply flow meter 242, which can detect the flow rate of the water-reducing agent synthesis liquid in the liquid supply pipe 241 to accurately control the delivery amount of the water-reducing agent synthesis liquid, further improving the preparation effect of the water-reducing agent.

[0090] Furthermore, such as Figure 4 As shown, the mixing and stirring mechanism 25 includes a rotary drive 251 and a mixing and stirring paddle 252. The rotary drive 251 is located at the upper end of the liquid inlet mixing tank 21, and the mixing and stirring paddle 252 is located inside the liquid inlet mixing tank 21 and is driven and connected to the rotary drive 251. The rotary drive 251 drives the mixing and stirring paddle 252 to swing to quickly mix the water-reducing agent synthesis liquid and water, which further improves the water-reducing agent preparation efficiency.

[0091] In embodiments of the present invention, such as Figure 4 As shown, the first liquid inlet device 20 also includes a second weighing scale 27. The liquid inlet stirring tank 21 is mounted on the second weighing scale 27, which is used to weigh the liquid inlet stirring tank 21. The controller 14 is communicatively connected to the second weighing scale 27 and the liquid supply pump 243 to accurately control the liquid supply pump 243 to adjust the flow rate of the water-reducing agent synthesis liquid in the liquid supply pipe 241 according to the weight of the liquid inlet stirring tank 21, thereby improving the preparation quality. In addition, a mixing temperature display instrument 28 is provided on the outer wall of the liquid inlet stirring tank 21 to facilitate the observation of the preparation heating temperature, further improving the preparation quality. Furthermore, both the reaction temperature display instrument 17 and the mixing temperature display instrument 28 can use temperature transmitters in the prior art, which are sensitive and have high temperature measurement accuracy.

[0092] In this embodiment of the invention, the water supply device 30 includes a main water supply pipe 31, a reaction water supply branch pipe 32, and a mixing water supply branch pipe 33. One end of the main water supply pipe 31 is connected to a water source, and the other end of the main water supply pipe 31 branches to the reaction water supply branch pipe 32 and the mixing water supply branch pipe 33. The reaction water supply branch pipe 32 is connected to the water inlet 112, and a first water supply valve 321 is provided on the reaction water supply branch pipe 32. The mixing water supply branch pipe 33 is connected to the liquid inlet stirring tank 21, and a second water supply valve 331 is provided on the mixing water supply branch pipe 33.

[0093] like Figure 5As shown, the main water supply pipe 31 is connected to a water source to supply water to the reaction water supply branch pipe 32 and the mixing water supply branch pipe 33 respectively. The reaction water supply branch pipe 32 is connected to the water inlet 112 on the reaction mixing tank 11 to provide water for the preparation of the water-reducing agent. The water supply in the reaction mixing tank 11 is adjusted by adjusting the opening of the first water supply valve 321. The mixing water supply branch pipe 33 is connected to the liquid inlet mixing tank 21 to provide water for the mixing water-reducing agent synthesis liquid. The water supply in the liquid inlet mixing tank 21 is adjusted by adjusting the opening of the second water supply valve 331. Both the first water supply valve 321 and the second water supply valve 331 are connected to the controller 14, which facilitates the control of the first water supply valve 321 and the second water supply valve 331, speeds up the response speed, and makes the operation convenient and quick.

[0094] In this embodiment of the invention, the liquid supply pipe 241 and the liquid inlet stirring tank 21, the first liquid inlet pipe 22 and the liquid inlet stirring tank 21 and the reaction stirring tank 11, the second liquid inlet pipe 41 and the reaction stirring tank 11, the reaction water supply branch pipe 32 and the reaction stirring tank 11, the mixing water supply branch pipe 33 and the liquid inlet stirring tank 21, and the return pipe 185 and the reaction stirring tank 11 can all be connected by PTFE-lined flexible joints in the prior art, which have the advantages of good corrosion resistance, non-adhesion and convenient and quick connection.

[0095] Furthermore, both the supply pump 243 and the inlet pump 43 can be centrifugal pumps from the prior art. Centrifugal pumps operate smoothly and have a compact structure, which gives the supply pump 243 and the inlet pump 43 the advantages of small size and small footprint, thus improving the space utilization rate within the skid-mounted container 50.

[0096] In this embodiment of the invention, the number of first liquid inlet devices 20 is set to multiple, and the liquid inlet stirring tanks 21 of the multiple first liquid inlet devices 20 are respectively used to hold various water-reducing agent synthesis liquids in a one-to-one correspondence. For example Figure 1 , Figure 3 and Figure 5 As shown, there are two first liquid inlet devices 20. One of them, the liquid inlet mixing tank 21, contains a mixture of acrylic acid and an initiator, such as hydrogen peroxide or ammonium persulfate. The other liquid inlet mixing tank 21 contains a mixture of chain transfer agent and reducing agent, such as 3-mercaptopropionic acid and VC or sodium formaldehyde sulfoxylate. The solid material inlet 113 contains HPEG (allyl polyoxyethylene ether) and VPEG (vinyl polyethylene glycol ether) and other macromonomer solid materials. The second liquid inlet pipe 41 delivers liquid alkali and an initiator to the liquid inlet. The solid material, water, liquid inlet, and the two liquid inlets are added to the reaction mixing tank 11 for heating and stirring to prepare the liquid inlet on-site. This ensures the quality of the liquid inlet and allows for flexible adjustment of the amounts of solid material, water, liquid inlet, and the two liquid inlets according to the actual needs of concrete mixing. The preparation is flexible and convenient.

[0097] Those skilled in the art will understand that the number of the first liquid inlet device 20 of the present invention is not limited to two as described above. The number of the first liquid inlet device 20 may also be three, four or other numbers. The number of the first liquid inlet device 20 can be flexibly set according to the type and quantity of the water-reducing agent synthesis liquid. The water-reducing agent synthesis equipment of the present invention does not limit the number of the first liquid inlet device 20.
