Description

Technical Field

[0001] This invention relates to the field of chemical reaction equipment technology, and in particular to a carbon-based natural latex composite reaction chamber. Background Technology

[0002] Rubber compounding is a bottleneck in rubber processing technology and a key factor in the performance of rubber products. The energy consumption of rubber compounding is enormous, accounting for almost 40% of the total energy consumption in rubber product production. Therefore, technological innovation in rubber compounding processes has attracted considerable attention in recent years, with wet compounding technology being a recent research focus. "Wet compounding" is a method of adding fillers such as carbon black and silica to rubber while it is still in its latex state (natural or synthetic latex), thoroughly mixing and dispersing it through stirring, and then producing a compound through flocculation (co-precipitation). The polymer-filler homogeneous dispersion prepared by this method is called "co-precipitated rubber." Compared with dry compounding, wet compounding has the following advantages: 1. It can significantly reduce the energy consumption of rubber compounding and lower costs (by reducing the number of compounding stages and compounding time); 2. It can significantly improve the dispersion of various reinforcing fillers in the rubber polymer, and the physical properties of the compound, such as tensile strength, elasticity, heat generation, and rolling resistance, are greatly improved; 3. It can significantly reduce dust pollution; 4. It is conducive to the realization of advanced continuous compounding processes.

[0003] However, existing compounding reaction chambers suffer from insufficient mixing. Due to the incompatibility between carbon black slurry and natural latex, existing compounding reaction chambers make it difficult to fully mix the carbon black slurry and natural latex. This results in carbon black being difficult to co-precipitate with natural latex, uneven dispersion of carbon black in natural latex, and the presence of particulate matter that is difficult to decompose. Consequently, the carbon black filling amount in the compound fluctuates greatly, and the dispersion uniformity is poor. Therefore, the compound cannot have good performance, making it difficult to promote the wet rubber compounding process and apply it on a large industrial scale. Summary of the Invention

The flow guiding unit 3 is used to guide the preliminary mixture into the stirring unit 4, and in this process, it can also refine the larger particles in the preliminary mixture to improve the mixing effect.

[0062] Specifically, the stirring unit 4 is located below the flow guiding unit 3, and the stirring unit 4 is directly connected to the flow guiding cylinder 17 in the flow guiding unit 3 above. The stirring unit 4 is used to stir the mixture after the initial mixing multiple times, so that the mixture is mixed again.

In addition, the flow guiding unit 3 can refine large particles in the mixture into small particles, which greatly improves the mixing of carbon black slurry and natural latex.

[0065] like Figure 2 As shown in the embodiments of this application, a carbon-based natural latex composite reaction chamber is provided, wherein the mixing unit 2 includes:

[0068] Specifically, the high-pressure input pump 8 is installed on the carbon black slurry input pipe 6 outside the composite reaction chamber 1. The high-pressure input pump 8 has the function of adjusting the flow rate and pressure of the carbon black slurry, so that the carbon black slurry can enter the mixing box 10 at a certain flow rate and pressure and be mixed with the natural latex in the mixing box 10.

[0069] A natural latex flow detector 9 is installed on the natural latex input pipe 7. The natural latex flow detector 9 is used to detect the flow rate of natural latex input into the mixing tank 10.

[0073] like Figure 3 As shown in the embodiments of this application, a carbon-based natural latex composite reaction chamber is provided, wherein the stirring unit 4 includes:

[0074] The mixing tank 13 is located inside the composite reaction chamber 1;

[0075] Specifically, the mixing tank 13 is located at the bottom of the composite reaction chamber 1. The mixing of the mixture in the mixing tank 13 is the last step in the mixing process. The mixing of the mixture in the mixing tank 13 will further increase the dispersibility of the carbon black slurry in the natural latex and improve the performance of the obtained rubber.

[0076] A stirring shaft 14 is disposed inside the mixing tank 13 and is used to stir the mixture at a certain speed.

[0077] Specifically, the stirring shaft 14 is vertically arranged inside the mixing tank 13. When the mixture enters the mixing tank 13, the stirring shaft 14 is activated to stir the mixture at a certain speed to ensure that it is fully mixed.

[0078] like Figure 4 As shown, the flow guiding unit 3 includes:

[0079] A mixture flow detector 16 is disposed above the mixing tank 13 and is used to detect the flow rate of the mixture flowing into the mixing tank 13;

[0080] The acquisition module is electrically connected to the mixed liquid flow detector 16, and the control module is electrically connected to the stirring shaft 14.

[0081] In an embodiment of this application, a carbon-based natural latex composite reaction chamber is provided. The acquisition module is used to acquire the flow rate ΔG of the natural latex flowing into the mixing tank 10 in real time, and the control module is used to control the high-pressure input pump 8.

[0082] The processing module is used to set the preset flow rate value G0 of standard natural latex. The processing module is also used to set the first preset flow rate difference g1, the second preset flow rate difference g2, the third preset flow rate difference g3, and the fourth preset flow rate difference g4 of natural latex, where g1 < g2 < g3 < g4. The processing module is also used to set the first preset working condition matrix A1 (a1, b1), the second preset working condition matrix A2 (a2, b2), the third preset working condition matrix A3 (a3, b3), and the fourth preset working condition matrix A4 (a4, b4), where a1 to a4 are the first to fourth preset input flow rates, where a1 < a2 < a3 < a4, and b1 to b4 are the first to fourth preset input pressures, where b1 < b2 < b3 < b4.

[0083] The preset working condition matrix A is selected as the working condition of the high-pressure input pump 8 based on the difference between the flow rate ΔG of the natural latex flowing into the carbon black slurry input unit and the preset value G0 of the standard natural latex flow rate.

[0085] When g1 < △G-G0 ≤ g2, the second preset working condition matrix A2 is selected as the working condition of the high-pressure input pump 8;

[0086] When g2 < △G - G0 ≤ g3, the third preset working condition matrix A3 is selected as the working condition of the high-pressure input pump 8;

[0087] When g3 < △G - G0 ≤ g4, the fourth preset working condition matrix A4 is selected as the working condition of the high-pressure input pump 8;

[0088] When the i-th preset working condition matrix Ai is selected as the working condition of the high-pressure input pump 8, the control module controls the high-pressure input pump 8 to work with the i-th preset input flow rate ai, and the control module will also control the high-pressure input pump 8 to work with the i-th preset input pressure bi, i = 1, 2, 3, 4.

[0089] Specifically, the operating conditions of the high-pressure input pump 8 are selected based on the difference between the flow rate of natural latex flowing into the carbon black slurry input unit and the preset value of the standard natural latex flow rate, so that the carbon black slurry and natural latex are mixed in a certain proportion. Furthermore, the high-pressure input pump 8 adjusts the pumping pressure of the carbon black slurry according to the amount of natural latex, so that the carbon black slurry enters the natural latex at a certain speed, achieving a good dispersion effect and improving dispersibility.

[0090] In an embodiment of this application, a carbon material natural latex composite reaction chamber is provided. The acquisition module is also used to acquire the flow rate ΔS of the mixed liquid above the mixing tank 13 in real time, and the control module is used to control the stirring shaft 14.

[0091] The acquisition module is used to set a preset value S0 for the standard mixed liquid flow rate. The acquisition module is also used to set a first preset mixed liquid flow rate difference s1, a second preset mixed liquid flow rate difference s2, a third preset mixed liquid flow rate difference s3, and a fourth preset mixed liquid flow rate difference s4, where s1 < v2 < s3 < s4. The processing module is also used to set a first preset working condition matrix W1(d1, e1), a second preset working condition matrix W2(d2, e2), a third preset working condition matrix W3(d3, e3), and a fourth preset working condition matrix W4(d4, e4), where d1 to d4 are the first to fourth preset stirring speeds, and d1 < d2 < d3 < d4, and e1 to e4 are the first to fourth preset stirring times, and e1 < e2 < e3 < e4.

[0092] The working conditions of the stirring shaft 14 are selected based on the difference between the flow rate ΔS of the mixture above the mixing tank 13 and the preset value G0 of the standard mixture flow rate.

[0093] When △S-S0≤g1, the first preset working condition matrix W1 is selected as the working condition of the stirring shaft 14.

[0095] When s2 < △S - S0 ≤ s3, the third preset working condition matrix W3 is selected as the working condition of the stirring shaft 14.

[0096] When s3 < △S - S0 ≤ s4, the fourth preset working condition matrix W4 is selected as the working condition of the stirring shaft 14.

[0097] When the i-th preset working condition matrix Wi is selected as the working condition of the stirring shaft 14, the control module controls the stirring shaft 14 to work at the i-th preset stirring speed di, and the control module controls the stirring time of the stirring shaft 14 to be set to the i-th preset stirring time ei, i = 1, 2, 3, 4.

[0098] Specifically, the working conditions of the stirring shaft 14 are selected based on the difference between the flow rate of the mixed liquid above the mixing tank 13 and the preset value of the standard mixed liquid flow rate. This allows the stirring shaft 14 to set its operating parameters according to the amount of mixed liquid, so as to fully stir the mixed liquid at the optimal stirring speed and stirring time, ensuring that the mixed liquid is fully mixed.

[0099] In an embodiment of this application, a carbon-based natural latex composite reaction chamber is provided, wherein the mixing unit 2 includes:

[0100] Spray head 11 is located at the top inside the mixing box 10 and is used to spray carbon black slurry;

[0101] An electronic switching valve 12 is located at the bottom of the mixing tank 10 and is electrically connected to the control module for controlling the opening and closing of the bottom outlet of the mixing tank 10.

[0102] Specifically, the bottom outlet of the mixing tank 10 is normally closed. When the carbon black slurry is sprayed into the natural latex through the spray head 11 and mixed in the mixing tank 10, the control module controls the electronic switch valve 12 to open the bottom outlet of the mixing tank 10, allowing the mixture to enter the next process.

[0103] In an embodiment of this application, a carbon-based natural latex composite reaction chamber is provided, wherein the flow guiding unit 3 further includes:

[0104] The guide pipe 15 is connected below the mixing unit 2 and is used to guide the mixture.

[0105] The guide tube 17 is located below the guide pipe 15 and is connected to the stirring unit 4, and is used to refine the particulate matter in the mixture.

[0106] Specifically, the guide tube 17 has a conical structure, resembling a funnel. Due to the large cross-section of the guide tube 15 and the slow flow rate, larger solid particles in the mixture will move downwards. When they move downwards into the guide tube 17, the cross-section becomes smaller, and the upward flow rate of the mixture increases, causing the solid particles to be swept up and move upwards. This process is repeated until they dissolve into smaller particles. This prevents excessive large solid particles from entering the mixing tank 13 and forming sediment that could block the inlet of the mixing tank 13. As a result, the solid particles in the mixture entering the mixing tank 13 are smaller, thus eliminating sedimentation problems during operation.

[0107] In an embodiment of this application, a carbon material natural latex composite reaction chamber is provided. A mixing tank 13 is connected to a mixed liquid outlet pipe 18 on one side, which is used to discharge the mixed liquid after stirring.

[0108] In an embodiment of this application, a carbon material natural latex composite reaction chamber is provided, wherein the spray head 11 is provided with a plurality of jet nozzles 19, which are used to spray carbon black slurry into the mixing box 10.

[0109] In summary, this invention provides a carbon-based natural latex composite reaction chamber, comprising: a composite reaction chamber 1, with a carbon black slurry input pipe 6 and a natural latex input pipe 7 connected to the composite reaction chamber 1; a mixing unit 2, disposed within the composite reaction chamber 1, for mixing the carbon black slurry and natural latex to form a mixture; a flow guiding unit 3, disposed below the mixing unit 2, for guiding the mixture; a stirring unit 4, disposed below the flow guiding unit 3, for stirring and remixing the mixture; and a control unit 5, including a data acquisition module, a processing module, and a control module, disposed within the composite reaction chamber 1, for automatically controlling the operation of the mixing unit 2, the flow guiding unit 3, and the stirring unit 4. This invention uses the mixing unit 2 to initially mix the carbon black slurry and natural latex, followed by a secondary stirring and mixing by the stirring unit 4, to ensure that the carbon black is fully dispersed in the natural latex, thereby improving the rubber's performance. Furthermore, the flow guiding unit 3 can refine large particles in the mixture into smaller particles.
