Description

[0001] This utility model relates to the field of polycarboxylate superplasticizer production technology, specifically to a polycarboxylate superplasticizer production device equipped with a transfer tank. Background Technology

[0002] Polycarboxylate superplasticizer is a high-performance water-reducing agent and a cement dispersant used in cement concrete. It is widely used in highway, bridge, dam, tunnel, and high-rise building projects. This product is environmentally friendly, non-flammable, non-explosive, and safe for transport by train and truck.

[0003] The production process of polycarboxylate superplasticizer is a polymer polymerization reaction, which is exothermic. During the reaction, the temperature inside the reactor reaches extremely high levels, posing a risk of overflow and overfilling. Therefore, this invention provides a polycarboxylate superplasticizer production device equipped with a transfer tank. When the reaction temperature inside the reactor becomes too high, the liquid material inside the reactor is stored in the transfer tank. Alternatively, if any of the initiation reactor or monomer reactor malfunctions, the material can also be stored in the transfer tank. The transfer tank serves as a backup tank to complete relevant production tasks, avoiding production stoppages that could lead to product defects and facilitating the production of polycarboxylate superplasticizer. Utility Model Content

The initiation vessel and the monomer vessel are connected to the reaction vessel through output pipes. The transfer tank is connected to an input pipe, which includes a main pipe and branch pipes. The main pipe is connected to three branch pipes, which are respectively connected to the initiation vessel, the monomer vessel, and the reaction vessel.

[0008] Furthermore: the initiation vessel, the monomer vessel, the reaction vessel, and the transfer tank are all equipped with a stirring shaft, which is connected to a motor.

[0010] Furthermore, the partition plate inside the reactor has a shaft hole, through which the stirring shaft extends.

[0011] Furthermore: the stirring shaft at the upper part of the partition is provided with a scraper, and the lower wall of the scraper is provided with multiple V-shaped protrusions, which are arranged in V-shaped grooves.

[0012] Furthermore, the diameter of the tube cover of the upper partition inside the reactor is larger than the diameter of the tube cover of the lower partition.

[0013] Furthermore: a temperature sensor is installed on the inner wall of the reactor, and a display is installed on the outer wall of the reactor; the temperature sensor and the display are electrically connected.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] See Figure 1-5 The present invention provides a polycarboxylate superplasticizer production device with a transfer tank, comprising: an initiation vessel 1, a monomer vessel 2, a reaction vessel 3, an intermediate pipe 4, a transfer tank 5, an output pipe 6, an input pipe 7, a main pipe 8, a branch pipe 9, a power pump 10, a discharge pipe 11, a flow regulating valve 12, a baffle plate 13, a stirring shaft 14, a motor 15, a stirring paddle 16, a scraper 17, a V-groove 18, a V-shaped convex plate 19, a temperature sensor 20, a display 21, and a pipe cover 22.

[0026] The initiation vessel 1, the monomer vessel 2, the reaction vessel 3, and the transfer tank 5 are all designed as tank structures. Each of the initiation vessel 1, monomer vessel 2, and reaction vessel 3 is connected to a central pipe 4 at its lower part. The central pipe 4 of each of these vessels is connected to the transfer tank 5. Each of the initiation vessel 1 and monomer vessel 2 is connected to an output pipe 6 at its lower part. The output pipe 6 of each vessel is connected to the reaction vessel 3. The transfer tank 5 is connected to an input pipe 7, which includes a main pipe 8 and branch pipes 9. Three branch pipes 9 are connected to the main pipe 8. The inlet end of the main pipe 8 is connected to the transfer tank 5, and the main pipe 8 is connected to the initiation vessel 1, monomer vessel 2, and reaction vessel 3 respectively through the three branch pipes 9.

[0027] A power pump 10 and a check valve are installed on the intermediate pipe 4, the output pipe 6, and the main pipe 8. A discharge pipe 11 is connected to the reactor 3 and the transfer tank 5. A flow regulating valve 12 is installed on the intermediate pipe 4, the output pipe 6, the discharge pipe 11, and the branch pipe 9. A shut-off valve is installed on the intermediate pipe 4, the output pipe 6, and the branch pipe 9.

[0028] A stirring shaft 14 is installed in each of the initiation vessel 1, the monomer vessel 2, the reaction vessel 3, and the transfer tank 5. The stirring shaft 14 is connected to the motor 15, and a stirring paddle 16 is installed on the stirring shaft 14. The blades of the stirring paddle 16 are inclined, and the stirring paddle 16 is designed to be wider at the top and narrower at the bottom, and the surface of the stirring paddle 16 is smooth.

[0029] The reactor 3 is equipped with multiple baffles 13, each with a shaft hole. The stirring shaft 14 extends through the shaft hole of the baffle 13. The baffles 13 are provided with V-shaped grooves 18, which are circular groove structures. There are multiple V-shaped grooves 18, and the V-shaped grooves 18 on each baffle 13 are coaxially arranged. The radius of the outer V-shaped groove 18 on each baffle 13 gradually decreases from the radius of the inner V-shaped groove 18.

[0030] The partition plate 13 at the lower part of the groove 18 has evenly spaced pipe caps 22, and the diameter of the pipe cap 22 on the upper partition plate 13 is larger than that on the lower partition plate 13. The scraper 17 has multiple V-shaped protrusions 19 on its lower wall, and the V-shaped protrusions 19 are located in the V-groove 18.

[0031] A temperature sensor 20 is installed on the inner wall of the reactor 3, and a display 21 is installed on the outer wall of the reactor 3. The temperature sensor 20 and the display 21 are electrically connected.

[0032] The initiation vessel 1, the monomer vessel 2, the reaction vessel 3, and the transfer tank 5 are equipped with feed pipes at the top, and the feed pipes are equipped with pipe caps 22 to facilitate the addition of materials.

[0033] Pressure gauges are installed on the initiation vessel 1, the monomer vessel 2, the reaction vessel 3, and the transfer tank 5. Vent pipes with safety valves are also installed on these vessels. This facilitates pressure adjustment in the initiation vessel 1, the monomer vessel 2, the reaction vessel 3, and the transfer tank 5.

[0034] Working process: Production materials, which are liquids, are added to initiation reactor 1 and monomer reactor 2. These materials enter reaction reactor 3 through output pipe 6. In reaction reactor 3, the materials are mixed to produce polycarboxylate superplasticizer mother liquor. The production of polycarboxylate superplasticizer is an exothermic reaction, posing a risk of overheating and overflow. The materials in reaction reactor 3 enter transfer tank 5 through intermediate pipe 4. Transfer tank 5 serves as a backup tank to complete the relevant production work. Alternatively, if either initiation reactor 1 or monomer reactor 2 malfunctions, the materials enter transfer tank 5, which also serves as a backup tank to complete the relevant production work, preventing production stoppages and product defects.

[0035] The transfer tank 5 serves as a backup tank for any one of the initiation vessel 1, the single-unit vessel 2, and the reaction vessel 3. When the material in the transfer tank 5 needs to be re-entered into any one of the initiation vessel 1, the single-unit vessel 2, or the reaction vessel 3, the material in the transfer tank 5 is output through the main pipe 8 and enters through the branch pipe 9.

[0036] The materials in the reactor 3 and the transfer tank 5 are discharged through the discharge pipe 11. The power pump 10 installed on the intermediate pipe 4, the output pipe 6, and the main pipe 8 serves as the power transmission device. The intermediate pipe 4, the output pipe 6, the discharge pipe 11, and the branch pipe 9 are equipped with flow regulating valves 12, which are used to regulate the output amount.

[0037] Each of the initiation vessel 1, the monomer vessel 2, the reaction vessel 3, and the transfer tank 5 is equipped with a stirring shaft 14. A motor 15 drives the stirring shaft 14 to rotate, which in turn drives the stirring paddle 16 to move, thus achieving the stirring effect. The stirring paddle 16 has an inclined blade design, with the blades being wider at the top and narrower at the bottom (i.e., the blade thickness is thicker at the top and thinner at the bottom). The surface of the stirring paddle 16 is smooth to reduce material adhering to it and facilitate stirring. The motor 15 uses a common drive structure, which drives the stirring shaft 14 to rotate, and the stirring paddle 16 on the stirring shaft 14 also rotates, thus achieving stirring.

[0038] The reactor 3 is equipped with multiple baffles 13, each baffle 13 having multiple V-shaped grooves 18 evenly distributed on it. The V-shaped grooves 18 are circular groove structures with an open top. The baffles 13 below the V-shaped grooves 18 have evenly distributed tube covers 22. The stirring shaft 14 at the top of the baffles 13 is equipped with scrapers 17, which have multiple V-shaped protrusions 19. One side of the V-shaped protrusions 19 is placed inside the V-shaped grooves 18, and the wall of the V-shaped protrusions 19 is set to fit against the inner wall of the V-shaped grooves 18. The movement of the V-shaped protrusions 19 reduces the agglomeration of particles, allowing the material to pass through the tube covers 22. The baffles 13 have multiple holes, and the tube cover 22 of the upper baffles 13 has a larger hole diameter than that of the lower baffles 13. After passing through the V-shaped grooves 18 of the multiple baffles 13 and the V-shaped protrusions 19 of the scrapers 17, the impact of particle agglomeration is reduced, ensuring that the produced product meets the requirements.

[0039] A temperature sensor 20 is installed inside the reactor 3. The temperature sensor 20 is connected to the display 21 to facilitate monitoring of the temperature inside the reactor 3. The temperature sensor 20 and the display 21 used in this application are both commercially available conventional devices. The connection method between the temperature sensor 20 and the display 21 is also a conventional electrical connection. The temperature sensor 20 monitors the temperature inside the reactor 3, and the temperature is displayed through the circuit-connected display 21, so that the temperature inside the reactor 3 can be known.

More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims.
