Description
Technical Field
[0001] This utility model relates to the technical field of pulping apparatus for preparing intumescent fire-retardant coatings, specifically to a pulping apparatus for the preparation process of intumescent fire-retardant coatings. Background Technology
[0002] Fire-retardant coatings are special coatings applied to the surface of combustible substrates to reduce the flammability of the coated material, inhibit the rapid spread of fire, and improve the fire resistance limit of the coated material. They are applied to the surface of combustible substrates to change the surface combustion characteristics of the material and inhibit the rapid spread of fire, or applied to building components to improve the fire resistance limit of the components. There are many types of fire-retardant coatings, among which intumescent fire-retardant coatings are one type. A key step in the production process of intumescent fire-retardant coatings is the precise pouring of raw materials such as binders, chemical additives, and aggregates into a slurry tank for mixing. This step aims to effectively convert powdered and liquid raw materials into a uniform slurry for subsequent processes. However, ordinary slurry tanks often face the problem of powdered raw materials sticking to the inner wall of the slurry preparation device when manufacturing the slurry. This not only increases the difficulty of cleaning but also seriously affects the slurry preparation effect, leading to a decrease in the uniformity and quality of the slurry.
[0003] Furthermore, during the mixing and pulping process, due to the differences in physical properties between the adhesive and powdered raw materials, it often takes a long time to fully mix all the raw materials evenly. This uneven mixing not only affects the performance of the final product but also increases the production cycle and cost. More importantly, a certain amount of particulate matter is often generated after pulping. These particulate matter may be due to incomplete dispersion of raw materials or agglomerates formed during the mixing process. The presence of these particulate matter will further reduce the quality of the raw material pulp and have an adverse effect on the film-forming properties, fire resistance, and application performance of subsequent coatings. Therefore, in order to address the above problems, a series of measures need to be taken to optimize the pulping process. Utility Model Content
[0004] The purpose of this invention is to provide a slurry preparation device in the preparation process of intumescent fire-retardant coatings, so as to solve the problems mentioned in the background art.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A slurry preparation device for the preparation of an intumescent fire-retardant coating includes a support, a filter assembly, a stirring assembly, and a valve port. A slurry tank is fixedly installed on the upper end of the support, and a motor is fixedly installed on the upper end of the slurry tank. A drive wheel is fixedly installed on the output end of the motor. The filter assembly is fixedly installed inside the slurry tank and includes a rotating ring rotatably mounted on the inner wall of the slurry tank. A first gear ring is fixedly installed on the upper end of the rotating ring and meshes with the drive wheel. A filter tank is fixedly installed inside the rotating ring, and a plurality of filter holes are equidistantly opened on the side wall of the filter tank, with the filter holes penetrating the side wall of the filter tank. The stirring assembly is rotatably mounted on the upper end of the slurry tank. The valve port is fixedly installed on the lower end of the slurry tank.
[0007] Using the above technical solution, when workers use the equipment, they first add the slurry into the filter tank and then turn on the motor. The drive wheel at the motor output end drives the first gear ring on its lower side to rotate, which in turn drives the rotating ring fixedly connected to the first gear ring to rotate, thereby driving the filter tank to rotate. The slurry in the filter tank is screened by the rotation of the filter tank, and the particles are retained in the filter tank. The filtered slurry flows into the pulping tank through the filter holes. Through the setting of the filter components, the automatic screening of the slurry is realized. As the filter tank continues to rotate, the slurry is evenly dispersed and filtered through the filter screen. Impurities and particles are effectively intercepted, while the clean slurry, under the action of gravity, passes through the filter holes and flows into the pulping tank below. This process not only ensures the high efficiency and stability of the filtration effect, but also greatly improves the continuity and automation level of the production process.
[0008] A further improvement of this utility model is that: the stirring assembly includes a transmission ring, which is rotatably mounted on the upper end of the slurry tank; a second gear ring is fixedly mounted on the lower end of the transmission ring; the second gear ring is meshed with the drive wheel; a plurality of limiting blocks are fixedly mounted at equal intervals on the upper end of the transmission ring; a first wing nut is provided on the limiting block; a limiting rod is fixedly mounted inside the limiting block; the end of the limiting rod away from the second gear ring is fixedly connected to the stirring rod; and stirring blades are fixedly mounted on the side wall of the stirring rod.
[0009] By adopting the above technical solution, in the working state, the setting of the stirring component makes the slurry flow more smoothly, effectively accelerating the efficiency of the slurry passing through the filter holes and flowing into the pulping tank below, thereby realizing an efficient and stable filtration and pulping process. Stirring also helps to break up some lumps and sediments in the slurry, ensuring the smoothness and stability of the slurry flow. Through the continuous action of the stirring component, the various components in the slurry are fully mixed, providing a more homogeneous and easy-to-handle raw material for the subsequent filtration and pulping process. The setting of the limiting block and limiting rod makes it easier to disassemble and remove the stirring component for subsequent cleaning.
[0010] A further improvement of this utility model is that a scraper is fixedly installed at the end of the stirring blade away from the stirring rod.
[0011] The above technical solution allows the scraper to be scraped off the slurry adhering to the side wall of the filter tank. At the same time, it can also scrape off the residual particles after filtration to prevent them from accumulating on the side wall and affecting the filtration efficiency.
[0012] A further improvement of this utility model is that an inner barrel is rotatably installed inside the filter barrel, and a filter hole corresponding to the filter barrel is opened on the side wall of the inner barrel.
[0013] By adopting the above technical solution, an inner tank is set inside the filter barrel. Before filtration, the inner tank can be used to block the filter holes and stir the slurry first to ensure that the solid particles in the slurry are evenly dispersed in the slurry. Then, the inner tank is opened to make the filtration efficiency of the filter holes more efficient. Secondly, through stirring, large particles or clumps in the slurry will be broken or dispersed, making them easier to pass through the subsequent filter holes, thereby improving the filtration efficiency.
[0014] A further improvement of this utility model is that: a number of slots are equidistantly provided on the upper end of the rotating ring, and a number of blocks are equidistantly provided on the upper end of the filter bucket. The blocks and slots fit together, and a number of handles are fixedly installed on the blocks.
[0015] The above technical solution involves opening a slot at the upper end of the rotating ring and setting a locking block on the filter barrel. This design allows the filter barrel to be removed using a handle, making subsequent cleaning of the filter components more convenient.
[0016] A further improvement of this utility model is that: a number of fixing blocks are fixedly installed at equal intervals on the upper end of the inner barrel, and a second butterfly nut is provided on the fixing blocks, and the fixing blocks are fixed to the card blocks by the second butterfly nut. Limiting strips are fixedly installed on the card blocks.
[0017] By adopting the above technical solution, the setting of the fixing block and the limiting strip makes the inner barrel more accurately open and close the filter hole during use, and the second butterfly nut makes the inner barrel more stable.
[0018] A further improvement of this utility model is that the bottom of the pulping tank is conical.
[0019] By adopting the above technical solution, it is possible to ensure smooth flow of slurry in the tank when it is taken out, avoid slurry accumulation and blockage at the bottom, make the discharge process more efficient and faster, and the conical design also helps to reduce slurry residue and improve slurry utilization.
[0020] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0021] 1. This utility model provides a slurry preparation device in the preparation process of intumescent fire-retardant coatings. Through the arrangement of a filter assembly, automatic slurry screening is achieved. As the filter tank continues to rotate, the slurry is evenly dispersed and filtered through the filter screen, effectively intercepting impurities and particulate matter. The clean slurry, under the action of gravity, passes through the filter holes and flows into the slurry preparation tank below. This process not only ensures high efficiency and stability of the filtration effect but also greatly improves the continuity and automation level of the production process. Simultaneously, the arrangement of the stirring assembly makes the slurry flow smoother. The stirring mechanism accelerates the flow of slurry through the filter holes into the pulping tank below, thus achieving a highly efficient and stable filtration and pulping process. The stirring also helps break up some lumps and sediments in the slurry, ensuring the smoothness and stability of the slurry flow. Through the continuous action of the stirring components, the various components in the slurry are fully mixed, providing a more homogeneous and easier-to-handle raw material for subsequent filtration and pulping processes. The scraper allows the slurry adhering to the side wall of the filter tank to be scraped off. At the same time, it can scrape off the residual particles after filtration to prevent them from accumulating on the side wall and affecting the filtration efficiency.
[0022] 2. This utility model provides a slurry preparation device in the preparation process of intumescent fireproof coating. By setting an inner tank inside the filter tank, the filter holes can be blocked by the inner tank before filtration to stir the slurry first, ensuring that the solid particles in the slurry are evenly dispersed in the slurry. Then, the inner tank is opened to make the filtration efficiency of the filter holes more efficient. Secondly, through stirring, large particles or clumps in the slurry will be broken or dispersed, making them easier to pass through the subsequent filter holes, thereby improving the filtration throughput and quality. At the same time, by setting the stirring component and the filter component to rotate in opposite directions, the shear force during the stirring process is increased, which helps to break or disperse large particles or clumps in the slurry. These smaller particles are easier to pass through the filter holes, thereby improving the filtration efficiency and throughput. The continuous rotation of the stirring component can continuously stir the slurry during the filtration process, preventing solid particles from depositing on the surface of the filter holes and forming blockages. At the same time, the rotation direction opposite to that of the filter component will produce a stronger flushing effect, better removing particles already attached to the filter tank.

[0032] The present invention will be further described in detail below with reference to embodiments:
[0033] Example 1
[0034] like Figure 1-7 As shown, this utility model provides a pulping device for the preparation process of intumescent fireproof coating, including a support 1, a filter assembly 5, a stirring assembly 10, and a valve port 11. A pulping tank 2 is fixedly installed on the upper end of the support 1, and a motor 3 is fixedly installed on the upper end of the pulping tank 2. A drive wheel 4 is fixedly installed on the output end of the motor 3. The filter assembly 5 is fixedly installed inside the pulping tank 2. The filter assembly 5 includes a rotating ring 6, which is rotatably installed on the inner wall of the pulping tank 2. A first gear ring 8 is fixedly installed on the upper end of the rotating ring 6. The first gear ring 8 is meshed with the drive wheel 4. A filter tank 7 is fixedly installed inside the rotating ring 6. A plurality of filter holes 9 are equidistantly opened on the side wall of the filter tank 7, and the filter holes 9 penetrate the side wall of the filter tank 7. The stirring assembly 10 is rotatably installed on the upper end of the pulping tank 2. The valve port 11 is fixedly installed on the lower end of the pulping tank 2.
[0035] In this embodiment, when the worker uses the equipment, the worker first adds the slurry into the filter tank 7 and then turns on the motor 3. The drive wheel 4 at the output end of the motor 3 drives the first gear ring 8 on its lower side to rotate, and drives the rotating ring 6 fixedly connected to the first gear ring 8 to rotate, thereby driving the filter tank 7 to rotate. The slurry in the filter tank 7 is screened by the rotation of the filter tank 7, and the particles are retained in the filter tank 7. The filtered slurry flows into the pulping tank 2 through the filter hole 9. Through the setting of the filter assembly 5, the automatic screening of the slurry is realized. As the filter tank 7 continues to rotate, the slurry is evenly dispersed and filtered through the filter screen. Impurities and particles are effectively intercepted, while the clean slurry passes through the filter hole 9 under the action of gravity and flows into the pulping tank 2 below. This process not only ensures the high efficiency and stability of the filtration effect, but also greatly improves the continuity and automation level of the production process.
[0036] like Figure 2 As shown, preferably, the stirring assembly 10 includes a transmission ring 12, which is rotatably mounted on the upper end of the pulping tank 2. A second gear ring 13 is fixedly mounted on the lower end of the transmission ring 12, and the second gear ring 13 is meshed with the drive wheel 4. A plurality of limiting blocks 17 are fixedly mounted at equal intervals on the upper end of the transmission ring 12. A first wing nut 18 is provided on the limiting block 17. A limiting rod 19 is fixedly mounted inside the limiting block 17. The end of the limiting rod 19 away from the second gear ring 13 is fixedly connected to the stirring rod 14. A stirring blade 15 is fixedly mounted on the side wall of the stirring rod 14.
[0037] In this embodiment, during operation, the stirring component 10 facilitates smoother slurry flow, effectively accelerating the slurry's passage through the filter holes 9 and into the pulping tank 2 below. This achieves a highly efficient and stable filtration and pulping process. The stirring also helps break up some lumps and sediments in the slurry, ensuring smooth and stable slurry flow. Through the continuous action of the stirring component 10, the various components in the slurry are fully mixed, providing a more homogeneous and easier-to-process raw material for subsequent filtration and pulping processes. The limiting block 17 and the limiting rod 19 allow the stirring component 10 to be disassembled and removed, making subsequent cleaning of the stirring component 10 more convenient.
[0038] like Figure 4 As shown, preferably, a scraper 16 is fixedly installed at the end of the stirring blade 15 away from the stirring rod 14.
[0039] In this embodiment, the scraper 16 is designed to scrape off the slurry adhering to the side wall of the filter tank 7. At the same time, it can scrape off the residual particles after filtration to prevent them from accumulating on the side wall and affecting the filtration efficiency.
[0040] Example 2
[0041] like Figure 6As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, an inner barrel 20 is rotatably installed inside the barrel wall of the filter barrel 7, and a filter hole 9 corresponding to the filter barrel 7 is opened on the side wall of the inner barrel 20.
[0042] In this embodiment, by setting an inner barrel 20 inside the filter barrel 7, the filter holes 9 can be blocked by the inner barrel 20 before filtration, and the slurry can be stirred first to ensure that the solid particles in the slurry are evenly dispersed in the slurry. Then the inner barrel 20 is opened to make the filtration efficiency of the filter holes 9 more efficient. Secondly, through stirring, large particles or clumps in the slurry will be broken or dispersed, making them easier to pass through the subsequent filter holes, thereby improving the throughput and quality of filtration.
[0043] Example 3
[0044] like Figure 3 and Figure 7 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a plurality of slots 21 are equidistantly provided on the upper end of the rotating ring 6, and a plurality of blocks 22 are equidistantly provided on the upper end of the filter bucket 7. The blocks 22 and the slots 21 fit together, and a plurality of handles 23 are stacked and fixedly installed on the blocks 22.
[0045] In this embodiment, by opening a slot 21 at the upper end of the rotating ring 6 and setting a locking block 22 on the filter bucket 7, the filter bucket 7 can be removed by the handle 23, making it more convenient to clean the subsequent filter components 5.
[0046] Example 4
[0047] like Figure 6 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, a plurality of fixing blocks 24 are fixedly installed at equal intervals on the upper end of the inner barrel 20, and a second butterfly nut 25 is provided on the plurality of fixing blocks 24, and the fixing blocks 24 are fixed on the locking blocks 22 by the second butterfly nut 25. Limiting strips 26 are fixedly installed on the locking blocks 22.
[0048] In this embodiment, the fixing block 24 and the limiting strip 26 enable the inner tub 20 to open and close the filter hole 9 more precisely during use, and the second butterfly nut 25 makes the inner tub 20 more stable.
[0049] like Figure 1 As shown, preferably, the bottom of the pulping tank 2 is conical.
[0050] In this embodiment, the conical design ensures that the slurry flows smoothly out of the pulping tank 2 when it is removed, avoiding slurry accumulation and blockage at the bottom, making the discharge process more efficient and faster. The conical design also helps to reduce slurry residue and improve slurry utilization.
[0051] The working principle of the pulping device in the preparation process of this intumescent fireproof coating will be explained in detail below.
[0052] like Figure 1-7 As shown, when the worker uses the equipment, they first add the slurry into the filter tank 7 and then turn on the motor 3. Before use, the worker controls the inner tank 20 to close the filter hole 9 by sliding the fixing block 24 on the limit strip 26. The drive wheel 4 at the output end of the motor 3 drives the filter assembly 5 to rotate. The drive wheel 4 rotates clockwise, which drives the first gear ring 8 on its lower side to rotate, and drives the rotating ring 6 fixedly connected to the first gear ring 8 to rotate, thereby driving the filter tank 7 to rotate. At the same time, the drive wheel 4 drives the second gear ring 13 on its upper side, which drives the stirring rod 14 in the stirring assembly 10 to stir. The mixing blade 15 rotates, and the scraper 16 at the end of the mixing blade 15 scrapes away slurry particles on the side wall of the filter tank 7, opening the filter hole 9 so that the filtered slurry flows into the pulping tank 2 through the filter hole 9. The filter assembly 5 enables automatic slurry screening. As the filter tank 7 continues to rotate, the slurry is evenly dispersed and filtered through the filter screen, effectively intercepting impurities and particles. The clean slurry, under gravity, passes through the filter hole 9 and flows into the pulping tank 2 below. This process not only ensures high filtration efficiency but also... This design improves efficiency and stability, significantly enhancing the continuity and automation of the production process. After pulping, the limiting rod 19 and limiting block 17 can be released using the first butterfly nut 18, allowing the removal of the fixed stirring assembly 10. Simultaneously, the filter assembly 5 can be removed for cleaning. After cleaning, the locking block 22 is placed in the locking groove 21, and the limiting rod 19 is placed in the limiting block 17, where the first butterfly nut 18 is used to limit it. In this design, the driving wheel 4 drives the first gear ring 8 and the second gear ring 13 to rotate in opposite directions, causing the stirring assembly 10 and the filter assembly 5 to rotate in opposite directions. This increases the shear force during stirring, helping to break or disperse large particles or clumps in the slurry. These smaller particles pass through the filter holes more easily, thus improving filtration efficiency and throughput. The continuous rotation of the stirring assembly 10 continuously agitates the slurry during filtration, preventing solid particles from depositing on the filter hole surface and forming blockages. At the same time, the rotation direction opposite to that of the filter assembly 5 produces a stronger scouring effect, better removing particles already attached to the filter tank 7.
[0053] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
