TECHNICAL FIELD
[0001] The utility model relates to the technical field of mechanical production equipment, specifically a production equipment for the manufacture of a polycarboxylic acid water reducer. STATE OF THE ART
[0002] A water reducer is a concrete additive that can reduce the amount of mixing water without significantly changing the slump of the concrete.
[0003] The reaction mechanism of the polycarboxylic acid water reducer is that alkenyl polyethers such as HPEG, TPEG, GPEG, VPEG, and unsaturated monomers such as acrylic acid, maleic acid, and acrylates undergo radical copolymerization under the initiation of the redox system, resulting in a chain reaction to form the polycarboxylic acid water reducer. The reaction temperature, the dropping process, and the mass transfer efficiency of the reaction vessel are the main factors affecting the quality of polycarboxylic acid water reducer products.
[0004] In recent years, polycarboxylic acid water reducer synthesized from 6C monomer (GPEG, VPEG) has emerged among many polycarboxylic acid water reducers due to its ambient and low-temperature production process, excellent product performance, and high cost-performance ratio. However, there are many discrepancies between the conventional polycarboxylic acid water reducer production equipment and the production of 6C water reducers. First, the conventional polycarboxylic acid water reducer production equipment mostly uses paddle or anchor impellers. Due to the structural design, a dead angle for stirring is created.After the A / B materials are drained, they remain in the upper layer of the reaction liquid, which poses a risk of explosion, often resulting in gel formation on the reaction vessel body. Second, the existing production equipment for polycarboxylic acid water reducers mostly uses jacket heating and agitation to increase the solubility of the polyether monomers.Due to the strong activity of the 6C monomer, the synthesis temperature of the water reducer is mostly controlled at room temperature and low temperature, and the heat transfer efficiency of the conventional jacket temperature control is generally not suitable for the preparation of 6C polycarboxylic acid water reducer; moreover, the A / B material dropping device mostly uses a single tube for dropwise addition, which is not conducive to the diffusion of the A / B material in the reaction liquid and negatively affects the quality of the water reducer.
[0005] To solve the above-mentioned technical problems, the industry has conducted research on improving stirring performance, improving heat exchange efficiency, and accelerating material mixing. The Chinese Utility Model Application Announcement No. CN 220803225 U describes a production equipment for a glass-lined reaction vessel, comprising a vessel body, the top of which is provided with an inlet port and a drip feed port, and the bottom of which is provided with a discharge port; the outer surface of the vessel body is covered with a jacket; a hose and a drip ring pipe are also provided in the vessel body; the lower end of the hose passes through the drip feed port into the interior of the vessel body and is connected to the drip ring pipe via a drip flange, and the drip ring pipe is each provided with a drip hole.The hose is attached to the drip feed port through the central flange, and the upper end of the hose is connected to the drip material line; the boiler body is provided with a cartridge body with open upper and lower ends, which is firmly mounted in the boiler body; inside the cartridge body there is a rotating shaft on which a lifting screw is mounted;One end of the rotary shaft passes through the top of the kettle body and is connected to the output port of the electric motor, and the other end is equipped with a U-shaped stirring blade located between the outer wall of the cartridge body and the inner wall of the kettle body. The reaction kettle forms flow channels with different flow directions inside, achieving efficient and uniform mixing of materials without dead corners, thereby improving the heat transfer and heat exchange efficiency and the efficiency of the synthesis reaction. The utility model improves the stirring performance to a certain extent, but for a large-volume reaction kettle, the upper layer of the reaction liquid is still in a certain stirring dead angle, and jacket temperature control and ring tube draining only improve the reaction to a certain extent.

[0025] At the lower end of the folded blade disc 14 of the agitator shaft 10 in the boiler body, a composite blade 15 is also provided, wherein the composite blade 15 has an outer ring 15.2 arranged on the upper layer and an inner ring 15.1 arranged on the lower layer, wherein the outer ring 15.2 is connected to the agitator shaft 10 via an upper supporting rod 15.3 and the inner ring 15.1 is connected to the agitator shaft 10 via a lower supporting rod 15.6.
[0026] The upper supporting rod 15.3 of the outer ring 15.2 is constructed similarly to the discharge pressure plate 12. A reverse-folded blade 15.5 is arranged on the upper supporting rod 15.3 of the inner ring, and a positive-folded blade 15.4 is arranged on the upper supporting rod 15.3 of the outer ring. A lower reverse-folded blade 15.7 is arranged on the lower supporting rod 15.6 of the inner ring 15.1.
[0027] A vertical folded plate 15.10 is also connected between the upper supporting rod 15.3 and the lower supporting rod 15.6. The outer sides of the outer ring 15.2 and the inner ring 15.1 are also connected to an inclined scraper 15.8. The inclined scraper 15.8 is in positive engagement with the bottom of the boiler body, and the lower end of the inclined scraper 15.8 extends to the lifting type 7 discharge valve at the lower end of the boiler body.
[0028] The inclined scraper 15.8 of the composite blade 15 cooperates with the folded plate to make the polyether solid flow and avoid bottom deposition, and the drain pressure disc 12, the folded blade disc 14, the multiple positive-folded and reverse-folded blades of the composite blade 15 cooperate with the multiple drive blades 13 and the guide cartridge 3, so that the liquid flows upward inside the cartridge and downward outside the cartridge, which greatly improves the mass transfer efficiency and has a positive effect on improving the dissolution efficiency, preventing local explosions, and accelerating heat exchange.
[0029] A guide cartridge 3 is also provided in the kettle body. The guide cartridge 3 comprises an upper part and a lower part, the inner diameter of the cartridge body of the guide cartridge 3 being larger than the rotational circumference of the plurality of drive blades 13, and the guide cartridge 3 is firmly connected to the inner wall of the kettle body via a plurality of supporting brackets 5. A gap exists between the upper and lower parts of the guide cartridge 3, the gap being able to accommodate the discharge pressure disc 12, which can rotate freely in the space formed by the gap. The guide cartridge 3 serves to generate a guide flow in a specific direction so that the materials are thoroughly mixed.
[0030] In the specific manufacturing process of the 6C-polycarboxylic acid water reducer, first, according to the proposed operation procedures and process maps, a nominal amount of water is added into the reaction vessel through the second liquid supply port 2.1, then the electric motor 9 is started and the stirring device is turned on, meanwhile, 6C-polyether is added through the solid supply port 1 for pre-stirring (6C-polyether is configured with an aqueous solution with a concentration below 55% and can be quickly dissolved by sufficient stirring under the synergistic action of the stirring device), the temperature in the vessel is read, and the integrated high and low temperature machine is started, so that the spherical tube coil 4 connected to the integrated high and low temperature machine starts to work and regulate the temperature.Initially, the temperature in the kettle is controlled at 10-15°C by the spherical tube coil 4. After the feeding is completed, the initiator is added through the second liquid feed port 2.1 and stirred for 5 minutes. Then, the integrated high and low temperature machine is shut down, the feed valve of the first liquid feed port 2 is opened, and materials A and B are dripped through the distributor 11. As the reaction progresses, the temperature gradually rises. When the dripping of materials A and B is completed, the temperature rises to approximately 20-25°C. Stirring and reaction are continued for another 30 minutes while maintaining heat, and then the lift-type discharge valve 7 at the bottom of the kettle is opened to discharge the material.
