The traditional production device usually adopts multiple reaction kettles in series or complex pipeline systems for step-by-step mixing. There are problems such as large equipment floor area, long process flow, high energy consumption and difficulty in realizing continuous production. Especially in the preparation of environmentally friendly anti-solvent water film-forming foam extinguishing agent, different physical properties of raw materials such as viscous polysaccharide solution and surfactant solution need to be processed in sequence and pH adjustment is required.

[0013] Compared with the prior art, the application has the following beneficial effects: 1, by setting the driving assembly, the isolation assembly and the feeding assembly, multi-step, partition, automatic circulation production in one reaction kettle can be realized, the anti-solvent water film-forming foam extinguishing agent can be integrated and precisely put into materials, different solutions can be correspondingly mixed, and the finished solution can be formed after mixing and stirring after meeting, and the continuous production only needs to be realized by a single driving assembly, so that the energy consumption of the equipment is reduced.

[0014] 2, by setting the isolation assembly, the single reaction kettle can be flexibly divided into two independent mixing chambers, the driving assembly in a switchable communication state is combined, the device can pre-mix a new batch of raw materials in the upper chamber, the lower chamber can mature or finally mix the previous batch of finished products, the continuous production circulation of pre-mixing-maturing-discharging is formed, the interval of batch production is shortened, and the equipment utilization rate and unit time capacity are improved.

[0021] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example: Figure 1 and Figure 2 As shown, an environmentally friendly solvent-resistant water-based film-forming foam fire extinguishing agent production device includes a reaction vessel 1 and a discharge pipe 11. The discharge pipe 11 is fixedly installed on the lower side of the reaction vessel 1. An electrically controlled valve is installed on the side of the discharge pipe 11. Inside the reaction vessel 1, a drive assembly 2 and an isolation assembly 3 are installed. The isolation assembly 3 is located at the center of the inside of the reaction vessel 1. The upper end of the drive assembly 2 extends out of the reaction vessel 1. A feeding assembly 4 is installed on the upper side of the reaction vessel 1 corresponding to the position of the drive assembly 2.

[0023] Single driver settings can be achieved by configuring driver component 2, and the overall system can switch between multiple states for use in subsequent component driving. like Figures 2 to 6As shown, the drive assembly 2 includes a first drive rod 21 and a second drive rod 22. The first drive rod 21 and the second drive rod 22 are disposed inside the reactor 1. The upper end of the first drive rod 21 penetrates the upper side of the reactor 1, and the lower end of the second drive rod 22 penetrates the lower side of the reactor 1. A first stirring rod 211 and a second stirring rod 221 are fixedly mounted in a circumferential array at equal intervals on the sides of the first drive rod 21 and the second drive rod 22, respectively, and the first stirring rod 211 and the second stirring rod 221 are attached to the inner side of the reactor 1. The second stirring rod 221 can limit and stabilize the second drive rod 22. A motor 23 is coupled to the upper side of a drive rod 21 and fixedly mounted on the upper side of the reactor 1 via a bracket. A power supply module 24, which is an integrated lithium battery, is fixedly mounted inside the first drive rod 21. A charging port 25 is fixedly mounted on the side of the power supply module 24 and extends through the first drive rod 21, allowing the power supply module 24 to be charged. A slot 26, which is a regular hexagonal slot, is provided on the upper center of the second drive rod 22 near the first drive rod 21 and extends through the lower side of the first drive rod 21. A first electric actuator 27 is installed and electrically connected to the power supply module 24 via contacts. A locking block 28 is fixedly installed at the output end of the first electric actuator 27 and is movably disposed inside the lower side of the first drive rod 21. The locking block 28 is a regular hexagonal block. A constraint ring 29 is provided between the first drive rod 21 and the second drive rod 22. The constraint ring 29 is rotatably connected to the sides of the first drive rod 21 and the second drive rod 22, respectively. Specifically, after the power supply module 24 is charged through the charging port 25, the power supply module 24 can supply power to the subsequent components. The electric power supply is relatively simple. When the motor 23 drives the first drive rod 21 to rotate, the first electric push rod 27 can push the locking block 28 to engage with the slot 26, so that the second drive rod 22 can rotate synchronously with the first drive rod 21. In addition, when the second drive rod 22 rotates or does not rotate, the second stirring rod 221 can fit against the bottom of the reactor 1 to constrain and stabilize the second drive rod 22, so that it can remain stable even when it is not driven. The constraint ring 29 can keep the first drive rod 21 and the second drive rod 22 in a concentric position at all times, without affecting the independent rotation of the first drive rod 21.

[0024] The internal space of the reactor 1 can be separated and connected by the isolation component 3, and can be switched in real time with a single drive. like Figure 3 and Figures 5 to 7As shown, the isolation assembly 3 includes a fixed plate 31, which is fixedly installed through the center of the reactor 1. The fixed plate 31 is an annular plate. A movable plate 32 is rotatably installed on the inner side of the fixed plate 31 and is movably sleeved on the side of the first drive rod 21. The movable plate 32 fits against both sides of the fixed plate 31. A sealing ring is provided on the side of the movable plate 32 so that its edge can fit tightly against the inner wall of the reactor 1. A first slot 311 is equidistantly formed in a circumferential array on the side of the fixed plate 31, and a second slot 321 is equidistantly formed in a circumferential array on the side of the movable plate 32. The first slot 311 and the second slot 321 are staggered by default. A constraint groove 33 is formed on the inner side of the movable plate 32. The constraint groove 33 is an annular groove. A second electric push rod 34 is equidistantly formed in a circumferential array on the side of the first drive rod 21 corresponding to the position of the fixed plate 31. 4. A constraint block 35 is fixedly installed inside the first drive rod 21 and electrically connected to the contacts of the motor 23. A constraint block 35 is fixedly installed on the side of the second electric push rod 34, and the constraint block 35 is partially movably positioned inside the constraint groove 33. The constraint block 35 is a wear-resistant rubber arc block with a convex cross-section. Specifically, the second electric push rod 34 is powered by the motor 23. The second electric push rod 34 pushes the constraint block 35, causing it to deform and fit tightly against the inner wall of the constraint groove 33. Subsequently, when the motor 23 drives the first drive rod 21 to rotate, the constraint block 35 drives the movable plate 32 to rotate relative to the fixed plate 31, so that the first slot 311 and the second slot 321 are in corresponding positions. At this time, the solution inside the reactor 1 can be circulated and transported. Subsequently, the movable plate 32 is driven to rotate, causing the positions of the first slot 311 and the second slot 321 to be staggered, so that the fixed plate 31 and the movable plate 32 cooperate to produce a sealing effect.

[0025] The feeding component 4 can accurately deliver the corresponding materials and can perform real-time detection, preventing incorrect feeding. like Figure 3 , Figure 5 , Figure 8 and Figure 9As shown, the feeding assembly 4 includes a first feed pipe 41, a second feed pipe 42, a third feed pipe 43, and a fourth feed pipe 44. These four feed pipes are arranged in a circumferential array at equal intervals around the first drive rod 21 and are fixed through and fixed to the top of the reactor 1. They are respectively connected to different external solution supply modules. A fixing frame 45 is fixedly installed on the lower inner side of the first feed pipe 41, the second feed pipe 42, the third feed pipe 43, and the fourth feed pipe 44. The fixing frame 45 is an L-shaped annular block. Stirring holes 451 are equally spaced through the fixing frame 45 on its side. The stirring holes 451 are funnel-shaped threads. A detection block 452, which is a ring-shaped pressure sensor, is fixedly installed on the lower side of the fixed frame 45. A movable rod 46, which is a cylindrical rod with a cross-shaped cross section and a tapered lower side, is movably installed on the inner center of the fixed frame 45. A blocking block 462, which is circular, is fixedly installed on the upper side of the movable rod 46 and fits against the upper side of the fixed frame 45, covering the agitation hole 451. A support cylinder 461, which is made of elastic material, is fixedly connected between the movable rod 46 and the side of the fixed frame 45 and is movably sleeved on the side of the movable rod 46. A corrugated cylinder has third electric actuators 47 equidistantly arranged on the side of the first drive rod 21. The third electric actuators 47 are fixedly installed inside the first drive rod 21 and electrically connected to the motor 23 contacts. A trigger block 48, which is a trapezoidal arc block, is fixedly installed at the output end of the third electric actuator 47. Specifically, the motor 23 supplies power to the third electric actuator 47, which can push and pull the trigger block 48 to move it to different positions. When the trigger block 48 corresponds to any position of the movable rod 46 in the first feed pipe 41, second feed pipe 42, third feed pipe 43, and fourth feed pipe 44, the trigger block 48... 8. Squeezing the movable rod 46 will push the block 462 away from the side of the fixed frame 45, and the solution in the corresponding pipeline can flow through the stirring hole 451 to the inside of the reactor 1. When the solution flows into the stirring hole 451, the spiral stirring can also have a certain defoaming effect on the solution. When the movable rod 46 is not squeezed, the elastic support of the support cylinder 461 can make the movable rod 46 pull the block 462 to fit against the upper side of the fixed frame 45, and the block 462 can block the stirring hole 451. When the support cylinder 461 is squeezed, the detection block 452 can detect the pressure change, record the data, and know the solution discharge of the corresponding pipeline.

[0026] Working principle: When using: First, premix the viscous solution, such as... Figure 10As shown, part of the third electric actuator 47 pushes the trigger block 48 to the position corresponding to the first feed pipe 41, and the remaining part of the third electric actuator 47 pushes the trigger block 48 to the position corresponding to the second feed pipe 42. At this time, when the motor 23 drives the first drive rod 21 to rotate, the trigger block 48 is pressed against the side of the movable rod 46 at the positions of the first feed pipe 41 and the second feed pipe 42, so that the movable rod 46 pushes the corresponding block 462 away from the upper position of the fixed frame 45. The detection block 452 obtains the pressure signal, records the data and feeds it back to the external controller, so that the material discharge status can be known. The first feed pipe 41 discharges the base liquid (i.e., pure water) into the reactor 1, and the second feed pipe 42 discharges the anti-solvent polysaccharide solution (such as xanthan gum) into the reactor 1. The first drive rod 21 drives the first stirring rod 211 to stir and mix the two solutions to form a viscous solution premix for later use. The second step is to premix the base solution, such as... Figure 11 As shown, the second electric actuator 34 pushes the constraint block 35 to deform and fit against the wall of the constraint groove 33. The movable plate 32 rotates synchronously with the first drive rod 21. The movable plate 32 can make the second slot 321 correspond to the first slot 311. The centrifugal force of the rotating movable plate 32 drives the solution to flow out through the second slot 321 and the first slot 311 to the bottom of the reactor 1. At the same time, the third electric actuator 47 pushes the trigger block 48 to the position of the fourth feed pipe 44. After the trigger block 48 squeezes the movable rod 46 on the side of the fourth feed pipe 44, the buffer solution (such as citric acid) flows into the reactor 1 and flows into the bottom of the reactor 1 at the same time with the viscous solution. At this time, the first electric actuator 27 pushes the locking block 28 to engage in the slot 26. The second drive rod 22 can rotate synchronously with the first drive rod 21 to continue to mix the viscous solution and the buffer solution to neutralize the pH value. Subsequently, the movable plate 32 rotates so that the second slot 321 and the first slot 311 are staggered. Then, the second electric actuator 34 pulls the constraint block 35 to reset. At this time, part of the third electric actuator 47 pushes the trigger block 48 to the position of the first feed pipe 41, and the rest of the third electric actuator 47 pushes the trigger block 48 to the position of the third feed pipe 43. The trigger block 48 squeezes the movable rod 46 in the first feed pipe 41 and the third feed pipe 43, thereby opening the two pipes. The first feed pipe 41 discharges the base liquid, and the third feed pipe 43 discharges the surfactant solution (such as hydrocarbon surfactants and fluorocarbon surfactants). Then, the first stirring rod 211 stirs and mixes the base liquid and the surfactant solution to form a premixed base solution for later use. The third step is to mix the finished solution and then circulate it for production. The same operation is performed so that the base solution flows into the bottom of the reactor 1. The second drive rod 22 rotates with the first drive rod 21, and the second stirring rod 221 stirs the base solution and the viscous solution to form the finished solution. The buffer solution is selectively added again according to the pH value of the finished solution. Subsequently, the movable plate 32 and the fixed plate 31 form an isolation closure, at which point the first step of operation can be carried out to produce a viscous solution. After a certain period of time, the first electric push rod 27 pulls the locking block 28 out of the slot 26. At this time, the second drive rod 22 stops being driven to rotate, and the finished solution can be allowed to stand and mature until the viscous solution on the upper side of the reactor 1 is completed. The finished solution is then discharged from the discharge pipe 11. The first electric push rod 27 pushes the locking block 28 again to engage with the slot 26, and the second step of operation can be carried out. In this way, the uninterrupted automated production cycle can be completed.

[0027] When no solution is needed, the third electric actuator 47 pushes and pulls the trigger block 48, which does not correspond to the positions of the first feed pipe 41, the second feed pipe 42, the third feed pipe 43, and the fourth feed pipe 44. This ensures that no material is discharged from each pipe, thus avoiding incorrect material discharge that could affect the quality of the finished product.

[0028] A preparation process for an environmentally friendly water-resistant film-forming foam fire extinguishing agent production device, such as... Figure 12 As shown, it includes the following steps: Step 1: Divide the interior of the reactor into two spaces; Step 2: First, pour the base solution and anti-soluble polysaccharide solution into the upper space of the reactor and premix and stir to form a viscous solution; Step 3: Make the inside of the reactor connected, and let the viscous solution flow into the lower space of the reactor. At the same time, the buffer solution can be added appropriately to adjust the pH value, and then it is separated again. Step 4: Then, the base solution and surfactant solution are discharged into the upper space of the reactor, premixed and stirred to form the base solution, while the viscous solution is continuously stirred. Step 5: Similarly, the base solution is poured into the lower space of the reactor. The viscous solution and the base solution are mixed and stirred to form the finished solution. A certain amount of buffer solution can also be released to adjust the pH value. Step 6: Synchronous circulation operation steps, the reactor is left to stand and mature in the lower space.
