Description

Technical Field

[0001] The present invention relates to the technical field of material forming, and particularly relates to a gel fire extinguishing agent and a mixing and forming device for its preparation. Background Art

[0002] In the field of fire protection, gel fire extinguishing agents are widely used in fire fighting and prevention due to their good adhesion, water retention, and anti-burning properties. However, in the preparation process of traditional gel fire extinguishing agents, there are still deficiencies in the mixing and forming device: existing mixing equipment usually cannot quickly and fully disperse dry powder raw materials such as gel dry materials and flame retardants in water, resulting in the swelling and agglomeration of some raw materials when encountering water, which affects the preparation efficiency of the gel fire extinguishing agent. At the same time, traditional devices lack effective anti-residue design, and raw materials are likely to adhere to the inner wall of the equipment and the surface of components, which not only affects the accuracy and quality of subsequent production, but also increases the difficulty of equipment cleaning and maintenance costs. Therefore, this application provides a gel fire extinguishing agent and a mixing and forming device for its preparation to meet the requirements. Summary of the Invention

[0013] Further, the guiding strip is provided with a wavy surface.

[0014] A gel fire extinguishing agent includes the above-mentioned mixing and forming device for preparing the gel fire extinguishing agent.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above solution, through the setting of the pre-mixing component, the first grinding disk and the second grinding disk cooperate, the hemispherical grinding block and the spiral grinding groove, and the circulating design of the through groove, the raw materials can be ground multiple times, effectively improving the refinement degree of the raw materials, ensuring that the components of the gel fire extinguishing agent are fully refined, preventing agglomeration, facilitating subsequent uniform mixing, and ensuring the fire extinguishing performance;

[0017] The pre-mixing and dispersion unit composed of the first fixed cylinder and the second fixed cylinder achieves the preliminary mixing and secondary pre-mixing of raw materials through the differential spraying effect generated by irregular round holes and the multiple collisions and rebounds brought about by the inclined design of the inner wall of the second fixed cylinder, enabling the full fusion of water and dry powder raw materials, ensuring the uniform mixing of the gel fire extinguishing agent, and improving the stability of the fire extinguishing effect;

[0018] The integrated structure of the feed pipe and the water inlet pipe injects water during the grinding process of raw materials. The water flow can wash the surfaces of the feed pipe, grinding disc and related components, flushing the attached materials to the discharge port, effectively avoiding raw material residues, reducing the cleaning work during the pretreatment process, improving the usage efficiency of the device, and reducing the maintenance cost;

[0019] The wavy feeding blades prevent raw materials from piling up during rotation, and at the same time increase the friction with the raw materials, ensuring that the raw materials enter the grinding area evenly and efficiently, and improving the efficiency and quality of mixing and grinding;

[0020] The concave-convex and inclined structure of the opposite surfaces of the first grinding disc and the second grinding disc, in cooperation with the through grooves, enables the material to slide automatically towards the discharge port under the inclined force during grinding, while reducing the wear of the grinding blocks, providing a stable grinding force, increasing the grinding effect and the service life of the device;

[0021] Through the setting of the dispersion component, when the material drips from the through hole, the first rotating rod drives the dispersion disc to rotate synchronously. The guiding strips on the dispersion disc come into contact with the dripping material. The guiding strips are designed with a wavy surface. On the one hand, it can effectively increase the contact area and contact time between the material and the guiding strips, making the material generate more complex movement trajectories on the surface of the guiding strips, achieving more thorough dispersion; on the other hand, the wavy surface structure can change the angle and direction of the material being thrown out, causing the material to impact the inner wall of the tank at different angles, further enhancing the dispersion effect, avoiding material agglomeration, and ensuring that the pre-mixed material is evenly dispersed in the tank through the coordinated action of the dispersion disc and the guiding strips;

[0022] Through the setting of the scraping component, the reciprocating thread groove of the second rotating rod cooperates with the thread sleeve to drive the scraper and the scraping blade to make reciprocating movements. The scraping blade, with high wear resistance and flexibility, closely adheres to the inner wall of the tank, scraping off the attached materials in a timely manner, significantly reducing the wall sticking phenomenon, and avoiding the pollution or waste of subsequent batches caused by material residues;

[0023] The unique curved surface shape of the mixing blades generates strong turbulence during rotation, cooperating with the scraping blades to fully stir and mix the scraped materials, avoiding uneven local material concentration, further improving the uniformity of material dispersion, and ensuring the quality of the gel fire extinguishing agent;

[0024] The inclined design of the scraping blade guides the scraped material to flow towards the discharge pipe, improving the discharge efficiency by utilizing gravity and the inertia of movement; the through holes on the inner wall of the scraping plate generate fluid shear force to refine the material particles, and at the same time play a dredging role when passing through the discharge pipe to prevent blockage and ensure the smooth progress of the discharge process;

[0025] The scraping blade is made of elastic material and can deform moderately according to the shape of the inner wall of the tank to ensure the scraping effect; the through holes on the scraping plate allow some materials to drip directly, avoiding accumulation on the scraping plate and causing secondary adhesion, and improving the working efficiency of the scraping component.

[0037] As shown in the figure, in order to clearly show the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. According to specific needs, those of ordinary skill in the art can adjust or modify these devices and environments, and the adjustments or modifications still fall within the scope of the appended claims. Detailed implementation manners

[0038] The following will describe in detail a gel fire extinguishing agent and its mixing and molding device for preparation provided by the present invention with reference to the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative methods for implementation; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0039] As Figures 1 - 10 shown, the embodiments of the present invention provide a gel fire extinguishing agent and its mixing and molding device for preparation, including a tank body 1. A premixing component 2 is installed on the inner wall of the tank body 1, and the premixing component 2 is used for pre-mixing materials. The tank body 1 is made of high-strength corrosion-resistant materials. An integrated structure of a feeding pipe 210 and a water inlet pipe 211 is provided at the top of the tank body 1. The feeding pipe 210 is responsible for transporting dry powder raw materials such as inorganic gel and flame retardant, and the water inlet pipe 211 is communicated with the feeding pipe 210 through a tee joint to realize the synchronous transportation of water and raw materials. When water enters the tank body 1, it can wash the surface of the feeding pipe 210 and the first grinding disc 202, effectively avoiding raw material residue. A high-torque driving motor 217 on the motor bracket 216 at the top of the tank body 1 provides power. The output shaft of the motor 217 passes through the top of the tank body 1 through a bearing and is rigidly connected to the first rotating rod 201 that vertically penetrates the tank body 1.

[0040] Specifically, the premixing component 2 includes a first rotating rod 201, and a corrugated blanking blade 5 and a first grinding disc 202 are fixedly assembled on the outer side wall of the first rotating rod 201. The corrugated blanking blade 5 adopts a bionic design, and its undulating curved surface structure can generate complex hydrodynamic effects during rotation: on the one hand, the wave crests and troughs of the blade act alternately to form a stirring effect similar to a vortex, causing the raw materials to form a three-dimensional motion trajectory on the surface of the first grinding disc 202, effectively preventing the accumulation of raw materials; on the other hand, the wavy contour of the blade edge increases the friction with the raw materials, ensuring that the raw materials can uniformly and efficiently enter the grinding area through the feed holes 209.

[0041] The first grinding disc 202 and the second grinding disc 203 form a core grinding unit. On the surface of the first grinding disc 202 facing the second grinding disc 203, a plurality of groups of fixedly distributed fixing blocks 204 are fixed. A hemispherical grinding block 205 is installed on each fixing block 204. These grinding blocks 205 are made of high-hardness alloy material, and their circular structure design can achieve extrusion contact with the material during rotation grinding, ensuring that the raw materials are uniformly and continuously extruded and broken in the grinding groove 206. A spiral-shaped grinding groove 206 is correspondingly arranged on the surface of the second grinding disc 203.

[0042] The through groove 207, as a key channel connecting the grinding groove 206 and the blanking port 208, adopts a gradient inclination design. Its inclination angle from the side of the grinding groove 206 to the side of the blanking port 208 is 5 - 10°, which can ensure the self-flow of raw materials by gravity while avoiding the reduction of the grinding effect caused by the excessive inclination angle resulting in the rapid sliding of raw materials, enabling the raw materials to form a "grinding, flowing, and re-grinding" circulation path during the grinding process. When the first rotating rod 201 drives the first grinding disc 202 to rotate, the raw materials are pressed into the grinding groove 206 under the action of centrifugal force and the grinding blocks 205 for primary crushing; subsequently, under the guidance of the inclined surface of the through groove 207, part of the raw materials flow towards the blanking port 208, while the other part re-enters the grinding area driven by the rotation of the grinding disc, realizing multiple cycle grindings and improving the refinement degree of the raw materials.

[0043] The first fixed cylinder 212 and the second fixed cylinder 214 extending below the second grinding disc 203 form a premixing and dispersing unit. The irregular round holes 213 distributed on the outer side wall of the first fixed cylinder 212 adopt a random matrix arrangement, and the aperture size changes in a gradient within the range of 3 - 15 mm, causing a differential jetting effect when the ground raw materials pass through the round holes 213 under the action of centrifugal force: large particle raw materials are thrown out at high speed from the large-aperture round holes 213, and small particle raw materials form a fine mist-like dispersed flow through the small-aperture round holes 213. The raw material flows with different speeds and directions collide and merge with each other in the second fixed cylinder 214 to achieve preliminary mixing.

[0044] The inner wall of the second fixed cylinder 214 is designed to be inclined, and its inclination angle forms a spatial linkage with the distribution of the circular holes 213 in the first fixed cylinder 212. When the raw materials enter the second fixed cylinder 214 from the first fixed cylinder 212, under the combined action of gravity and centrifugal force, they slide downward spirally along the inner wall. During this process, the raw materials collide and rebound with the inclined wall surface multiple times, further promoting the mixing uniformity. The through holes 215 evenly distributed at the bottom of the second fixed cylinder 214 are designed as the final mixing and discharging channels.

[0045] When preparing the gel fire extinguishing agent, first pour materials such as inorganic gel and flame retardant through the feed pipe 210, start the drive motor 217, and the motor 217 drives the first rotating rod 201 to rotate. The feeding blades 5 on the first rotating rod 201 send the materials on the top of the first grinding disc 202 to the second grinding disc 203 through the feeding port 208. The first rotating rod 201 continues to rotate, causing the first grinding disc 202 and the second grinding disc 203 to rotate relative to each other, grinding and crushing the materials with larger particles. The fixing blocks 204 on the first grinding disc 202 drive the circular grinding blocks 205 to further refine the materials in the grinding grooves 206. The grinding blocks 205 are designed to be circular, which can ensure uniform contact with the inner wall of the grinding grooves 206 during the grinding process, reduce wear, and at the same time provide a more stable grinding force, improving the grinding effect. In addition, the opposite surfaces of the first grinding disc 202 and the second grinding disc 203 are designed as concave-convex surfaces, and both sides close to each other are inclined. This structure enables the materials to slide automatically towards the feeding port 208 under the action of the inclined force during grinding; the setting of the through grooves 207 also assists the ground materials to move towards the feeding port 208 under the action of the inclined force. Subsequently, the pushing blades 6 on the first rotating rod 201 push the ground materials into the feeding port 208.

[0046] During the grinding process of materials such as inorganic gel and flame retardant, water is injected from the water inlet pipe 211. The water flows through the feed pipe 210 to the top of the first grinding disc 202. The first rotating rod 201 drives the feeding blades 5 to rotate, causing the water to flow over the surface of the materials. After the water enters between the first grinding disc 202 and the second grinding disc 203, it contacts the fixing blocks 204, grinding blocks 205, grinding grooves 206 and through grooves 207, washing away the materials attached to the surface of the components and flushing them to the feeding port 208, effectively avoiding material residue and reducing adhesion during the pretreatment process.

[0047] The material flows into the inner wall of the first fixed cylinder 212 with water from the feeding port 208. At this time, the rotating blades on the outer wall of the first rotating rod 201 start to work, pre-mixing the water and the material inside the first fixed cylinder 212. There are round holes 213 with irregular sizes and positions distributed on the first fixed cylinder 212. Under the action of the rotating blades, the pre-mixed material and water are thrown into the inner wall of the second fixed cylinder 214 through these round holes 213. The inner wall of the second fixed cylinder 214 is inclined, and there is a through hole 215 at the bottom. The thrown-in material slides along the inclined inner wall to achieve secondary pre-mixing, and finally drips downward through the through hole 215.

[0048] It should be noted that a plurality of exhaust valves are provided on the inner wall of the tank body 1. During the process of material treatment inside the tank body 1, the pressure inside the tank may increase due to various reasons (such as material reaction, stirring heat generation, etc.). The exhaust valves can be opened in a timely manner to release the excess gas, keep the pressure inside the tank within a safe range, and prevent safety accidents such as the rupture of the tank body 1 due to excessive pressure.

[0049] A dispersion assembly 3 is installed on the inner wall of the tank body 1. The dispersion assembly 3 is mainly used for deep dispersion treatment of the pre-ground material, effectively improving the dispersion uniformity and mixing effect of the material to meet the requirements of subsequent production processes for material quality.

[0050] Specifically, the dispersion assembly 3 includes a dispersion disk 301. The dispersion disk 301 is fixedly arranged on the outer wall of the first rotating rod 201. A number of guide bars 302 are fixedly arranged on the dispersion disk 301. The guide bars 302 are arranged in a circular array on the outer wall of the dispersion disk 301. The guide bars 302 are provided with a wavy surface 7, and the wavy surface 7 can break the straight flow state of the material, causing the material to roll and stir under the action of the wavy surface 7.

[0051] When the material drips from the through hole 215, the first rotating rod 201 drives the dispersion disk 301 to rotate synchronously. The guide bars 302 on the dispersion disk 301 come into contact with the dripping material. The guide bars 302 are designed with a wavy surface 7. On the one hand, it can effectively increase the contact area and contact time between the material and the guide bars 302, making the material generate a more complex movement trajectory on the surface of the guide bars 302 to achieve more sufficient dispersion. On the other hand, the wavy surface 7 structure can change the angle and direction of the material being thrown out, causing the material to impact the inner wall of the tank body 1 at different angles, further enhancing the dispersion effect, avoiding material agglomeration, and ensuring that the pre-mixed material is evenly dispersed in the tank body 1 through the synergistic effect of the dispersion disk 301 and the guide bars 302.

[0052] A scraping assembly 4 is installed on the inner wall of the tank body 1. The scraping assembly 4 is used to effectively reduce the phenomenon of the dispersed material sticking to the wall, avoid material residue from causing pollution or waste to subsequent production batches, and at the same time assist in completing the mixing and discharging of the material on the inner wall of the tank body 1.

[0053] Specifically, the scraping assembly 4 includes a second rotating rod 401. The second rotating rod 401 is rotatably arranged on the inner wall of the tank body 1 through a bearing. The second rotating rod 401 is fixedly connected to the first rotating rod 201, so that the two can rotate synchronously under the drive of the power system. A reciprocating thread groove 402 is formed on the outer side wall of the second rotating rod 401. The reciprocating thread groove 402 can provide power for the threaded sleeve 403 threadedly connected thereto to perform reciprocating linear motion during the rotation of the second rotating rod 401. When the second rotating rod 401 rotates, the threaded sleeve 403 performs periodic reciprocating motion along the axial direction of the second rotating rod 401 under the action of thread transmission. A plurality of scraping plates 404 are fixedly arranged on the outer side wall of the threaded sleeve 403. These scraping plates 404 are evenly distributed to form an annular scraping structure. A scraping blade 405 is fixedly arranged on one side of each scraping plate 404 close to the tank body 1. The scraping blade 405 is made of polyurethane material through a special surface treatment process, has high wear resistance and good flexibility, can closely fit the inner wall of the tank body 1, and under the drive of the threaded sleeve 403, the scraping blade 405 reciprocates with the scraping plate 404 to scrape off the material attached to the wall surface of the tank body 1 in time, effectively reducing the phenomenon of material sticking to the wall.

[0054] It is worth mentioning that a plurality of mixing blades 406 are also fixedly arranged on the outer side wall of the second rotating rod 401. These mixing blades 406 adopt a unique curved surface shape. During the rotation of the second rotating rod 401, they can generate a strong turbulence effect to fully mix the material scraped off from the inner wall of the tank body 1. The mixing blades 406 and the scraping blades 405 cooperate with each other. On the one hand, the scraping blades 405 scrape off the material on the tank wall, and on the other hand, the mixing blades 406 quickly remix the scraped material with other materials in the tank body 1 to avoid the occurrence of uneven local material concentration and further improve the dispersion uniformity of the material.

[0055] A discharge pipe 407 is connected to the inner wall of the tank body 1 for discharging the material after dispersion and mixing from the tank body 1. The scraping blade 405 is inclined. This design can guide the scraped material to flow along the inclined direction towards the discharge pipe 407, using gravity and movement inertia to assist the discharge of the material and improve the discharge efficiency. At the same time, a plurality of through holes 408 are formed in the inner wall of the scraping plate 404. These through holes 408 can generate fluid shear force during the movement of the scraping plate 404 to further refine the material particles, and when the scraping plate 404 passes near the discharge pipe 407, the through holes 408 can play a role in dredging to prevent the discharge pipe 407 from being blocked and ensure the smooth progress of the discharge process.

[0056] When the first rotating rod 201 rotates, it drives the second rotating rod 401 to rotate synchronously through a transmission mechanism. The reciprocating thread groove 402 on the surface of the second rotating rod 401 cooperates with the thread sleeve 403. As the second rotating rod 401 rotates, the thread sleeve 403 makes a reciprocating up-and-down motion along the reciprocating thread groove 402. The scraping plate 404 fixed on the thread sleeve 403 and the scraping blade 405 move accordingly, scraping the material thrown by the dispersion plate 301 onto the inner wall of the tank body 1. The scraping blade 405 is designed at an inclined angle, which can efficiently scrape off the material adhering to the inner wall of the tank body 1, preventing it from adhering to the inner wall and significantly reducing the wall-hanging phenomenon. At the same time, the scraping blade 405 is made of an elastic material and can be deformed moderately according to the shape of the inner wall during the scraping process to ensure the scraping effect. The scraping plate 404 is provided with a through hole 408. When scraping the material, some of the material can directly drip onto the inner wall of the tank body 1 through the through hole 408, preventing the material from accumulating on the scraping plate 404 and causing adhesion.

[0057] While the thread sleeve 403 drives the scraping plate 404 assembly to move, the mixing blade 406 on the second rotating rod 401 also rotates continuously, fully stirring and mixing the scraped material. After the gel fire extinguishing agent is mixed evenly and formed, the finished product can be discharged through the discharge pipe 407.
