Description

Technical Field

[0001] The present invention relates to the technical field of epoxy paint thinner production, and specifically to an impurity precise filtration and purification device in the continuous production of epoxy paint thinner. Background Art

[0002] Epoxy resin thinner is an additive used in combination with the base resin, which can effectively reduce the viscosity of the curing system, improve the fluidity of the material, make it easier to penetrate the surface of the substrate, and thus enhance the convenience of construction. By reducing the viscosity of the system, the thinner can reduce the resistance during construction, make the coating more uniform, and avoid uneven spreading caused by high viscosity. During the production process of epoxy resin thinner, filtration and purification are carried out. By filtering and purifying, tiny particle impurities, colloids, and suspended matters in the thinner can be removed, which can significantly improve the transparency of the thinner. The purified thinner has a more uniform molecular structure and lower viscosity, and better fluidity. This enables the thinner to mix more fully with the resin matrix during the mixing and processing of epoxy resin, ensuring good uniformity and operability of the mixture.

[0003] However, in the prior art, during the production process of epoxy resin thinner, the control of the fluid replenishment flow rate plays a crucial role in the effective interception of impurities. If the fluid replenishment flow rate continues to be too fast, it will lead to a significant increase in the impurity-carrying capacity of the fluid, causing the impurities to be subjected to a greater hydrodynamic force during the flow. The high-speed fluid will increase the kinetic energy of the impurities, making it more difficult for them to be intercepted by the filter medium. Impurities that were originally effectively intercepted by the filter medium can directly penetrate the filter layer due to the strong impact force, reducing the filtration efficiency. In addition, some impurities already attached to the filter medium can also be re-detached from the surface of the filter medium due to the strong fluid scouring effect, resulting in the re-entry of impurities into the fluid system and affecting the product purity. Summary of the Invention

[0004] The purpose of the present invention is to provide an impurity precise filtration and purification device in the continuous production of epoxy paint thinner to solve the problem proposed in the above background art that the high-speed fluid increases the kinetic energy of the impurities, making it more difficult for them to be intercepted by the filter medium.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An impurity precise filtration and purification device in the continuous production of epoxy paint thinner, including a purification cylinder, a filter screen is fixedly connected to the bottom end of the inner cavity of the purification cylinder, and a control mechanism is installed inside the purification cylinder; The control mechanism includes a rotating rod.

[0013] Preferably, a movable plate is arranged at one end of the inner side of the adjusting pipe. The movable plate is fixedly connected to the outer surface of the central rod.

[0014] Preferably, a fixed frame is rotatably connected to the top end of the stirring rod. Both bottom ends of the fixed frame are fixedly connected to the top of the purification cylinder. A stirring blade is fixedly connected to the bottom end of the stirring rod.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In the present invention, through the linkage of the swing rod, fixed block, linkage rod, crank and central rod, precise control of the fluid flow rate inside the regulating pipe is achieved, ensuring that the feeding flow rate is always maintained within an appropriate range. This effectively avoids the difficulty of sedimentation of impurities caused by too fast a flow rate and affects the filtration effect. At the same time, it prevents the filtration efficiency from being reduced due to too low a flow rate. The movement of the swing rod drives a series of transmission components to operate coordinately, causing the movable plate to rotate inside the regulating pipe, thereby realizing dynamic flow regulation.

[0016] 2. In the present invention, through the synergistic effect of the swing rod, connecting frame, lifting sleeve and transmission rod, the dynamic swing of the stirring rod is realized, thereby precisely controlling the angle and amplitude of the stirring blade. By optimizing the movement mode of the stirring rod, it can adapt to the filtration requirements of different fluid media, prevent impurity deposition in high-viscosity liquids, filter evenly and reduce energy consumption in low-viscosity liquids. The coordinated operation of the two stirring rods makes the stirring angle more flexible, improving the separation effect of particulate impurities, thereby enhancing the filtration accuracy. In addition, this mechanism can precisely adjust the stirring frequency and amplitude, ensuring the stability and efficiency of the filtration process, and ultimately improving the performance and reliability of the entire filtration system.

[0017] 3. In the present invention, the first driving motor drives the belt transmission component, causing the rotating rod, stirring rod and stirring blade to rotate synchronously, realizing the uniform mixing of epoxy paint thinner, preventing precipitation, and improving the filtration efficiency. The continuous disturbance of the stirring blade effectively prevents the deposition of particulate impurities, ensuring that the filtration process is more stable and reliable. In addition, the cooperation of the driving groove and the driving block ensures the stability of the equipment during movement, reduces interference and friction, extends the service life, reduces energy consumption. The overall system has the characteristics of efficient stirring and precise filtration, not only improving the production efficiency, but also enhancing the reliability and durability of the equipment.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Refer to Figure 1 - Figure 8 As shown in the figure: An impurity precise filtration and purification equipment during the continuous production of an epoxy paint thinner includes a purification cylinder 1. A filter screen 11 is fixedly connected to the bottom end of the inner cavity of the purification cylinder 1, and a control mechanism 5 is installed inside the purification cylinder 1; The control mechanism 5 includes a rotating rod 55, a lifting sleeve 56 is sleeved on the outer surface of the top end of the rotating rod 55, a driving groove 561 is provided on the outer surface of the top end of the lifting sleeve 56, transmission rods 57 are rotatably connected on both sides of the driving groove 561, the bottom end of the transmission rod 57 is rotatably connected to the stirring rod 58, a mounting surface 551 is provided in the middle of the rotating rod 55, and the top end of the stirring rod 58 is rotatably connected to the mounting surface 551, two support plates 512 are fixedly connected to the top of the purification cylinder 1, a swing rod 51 is rotatably connected between the two support plates 512, one end of the swing rod 51 is fixedly connected to a fixed block 52, the outer side of the fixed block 52 is rotatably connected to a first movable block 531, the top of the first movable block 531 is fixedly connected to a linkage rod 53, and the top of the linkage rod 53 is fixedly connected to a second movable block 532.

[0022] In this embodiment, when filtering, the feed flow rate of the feed pipe 4 is accurately controlled according to the actual filtering situation, so as to effectively avoid the problem of too fast flow rate. When the flow rate is too fast, the carrying capacity of impurities will be enhanced, resulting in the impurities being subjected to greater fluid dynamics at high flow rates, making it difficult to effectively settle and adhere to the filter medium, ultimately affecting the filtering effect and making the filtering incomplete.

[0023] When the flow rate is adjusted, the swing of the swing rod 51 drives the fixed block 52 to move accordingly. The swing rod 51 rotates around the support plate 512, and the movement of the support plate 512 further drives the first movable block 531 to move. Under the action of the first movable block 531, the linkage rod 53 also moves synchronously, and transmits the force to the two cranks 59 through the second movable block 532. When the crank 59 is subjected to the force transmission, it will start to swing around its fixed point, and the movement of the crank 59 will further drive the center rod 591 to rotate. The rotation of the center rod 591 will drive the movable plate 592 to rotate inside the regulating tube 42, thereby realizing the precise control of the fluid flow in the regulating tube 42.

[0024] Through the coordination of the regulating mechanism, the fluid flow rate can be dynamically regulated to keep it within an appropriate range, avoiding the filtration effect due to excessive flow rate and preventing the filtration efficiency from decreasing due to too low flow rate. In addition, it also has high stability and response speed.

[0025] Embodiment 2: Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, one end of the swing rod 51 is fixedly connected with a connecting frame 54. The inner wall of the connecting frame 54 is fixedly connected with a driving block 541. The driving block 541 is inserted into the driving groove 561 and is slidably connected with the driving groove 561. A first driving motor 2 is fixedly connected to the side wall of the purification cylinder 1. The output end of the first driving motor 2 is fixedly connected with a belt transmission assembly 21. The bottom of the purification cylinder 1 is fixedly communicated with a discharge port 3. The output end of the belt transmission assembly 21 is fixedly connected with the bottom end of the rotating rod 55. Two support frames 41 are symmetrically and fixedly connected to the top of the purification cylinder 1. The inner sides of the top ends of the support frames 41 are fixedly connected with a feed pipe 4.

[0026] In this embodiment, when the swing rod 51 swings, it will also drive the connecting frame 54 to move together. During this process, the connecting frame 54 uses the driving block 541 to cooperate with the driving groove 561 to apply a force to the lifting sleeve 56, so that the lifting sleeve 56 slides along the outer surface of the top end of the rotating rod 55 to achieve a lifting motion. As the lifting sleeve 56 moves up and down, the transmission rod 57 also moves synchronously, and then drives the stirring rod 58 to start swinging.

[0027] The swinging of the stirring rod 58 not only adjusts its own movement angle, but also affects the swinging direction and amplitude of the stirring blade 581. In this way, the two stirring rods 58 can operate coordinately, so as to effectively change the stirring angle of the stirring blade 581, enabling it to adapt to different filtration requirements and improving the filtration efficiency.

[0028] In addition, by adjusting the swinging amplitude and frequency of the stirring rod 58, a more precise stirring effect can be achieved in different filtration media. When the liquid is relatively viscous, a larger stirring angle helps to prevent impurity deposition, while when dealing with a thinner liquid, a smaller stirring angle can reduce energy consumption and ensure uniform filtration.

[0029] It not only improves the diversity of stirring, but also enables impurities of different particle sizes to be fully contacted in a shorter time and achieve effective separation through physical forces. This improved stirring mode can make impurities with larger particles and impurities with smaller particles be evenly distributed in the fluid, so as to ensure that each impurity particle has the opportunity to fully contact the filtration medium, effectively improving the separation efficiency. In addition, the design of precisely controlling the stirring angle enables the entire stirring process to be customized according to the characteristics of the filtration medium and the properties of the impurities. This precise control of the angle can not only avoid the re-dispersion of impurities caused by excessive agitation, but also ensure that each link in the filtration process is carried out under the best conditions, further improving the accuracy of impurity filtration. By optimizing the cooperation of the stirring angle and speed, impurities can be driven more efficiently towards the filtration equipment, improving the overall performance of the filtration system.

[0030] Example Three: According to Figure 4 and Figure 8As shown in the figure, a second driving motor 511 is installed on one side of the top of the purification cylinder 1, and the output end of the second driving motor 511 is fixedly connected to the middle part of the swing rod 51. Both ends of the top of the second movable block 532 are rotatably connected to a crank 59, and one side wall of one end of the crank 59 is fixedly connected to a central rod 591. The middle part of the feed pipe 4 is fixedly communicated with an adjusting pipe 42, and the inner wall of the adjusting pipe 42 is rotatably connected to one end of the central rod 591. One end of the inner side of the adjusting pipe 42 is provided with a movable plate 592, and the movable plate 592 is fixedly connected to the outer surface of the central rod 591. The top end of the stirring rod 58 is rotatably connected to a fixing frame 552, both ends of the bottom of the fixing frame 552 are fixedly connected to the top of the purification cylinder 1, and the bottom end of the stirring rod 58 is fixedly connected to a stirring blade 581.

[0031] In this embodiment, when the first driving motor 2 operates, it can drive the belt transmission assembly 21 to start moving, so that the belt transmission assembly 21 transmits power to the rotating rod 55, causing the rotating rod 55 to start rotating. During this process, the rotation of the rotating rod 55 will drive the stirring rod 58 and the stirring blade 581 to rotate synchronously, so that the epoxy paint thinner is evenly mixed in the stirring cavity, effectively preventing the occurrence of precipitation. At the same time, since the rotation of the stirring blade 581 can continuously apply disturbance to the liquid, the particulate impurities will not deposit during the flow process, thereby improving the efficiency of the subsequent filtration process and ensuring that the filtration effect is more stable and reliable.

[0032] In addition, during the entire stirring and filtering process, the presence of the driving groove 561 is crucial. Relative sliding can occur between the driving groove 561 and the driving block 541, so that the driving block 541 always maintains good cooperation with the driving groove 561 during the up and down movement. It can not only effectively bear the up and down acting force from the driving block 541, but also avoid movement interference during the rotation process, thereby ensuring the stability and reliability of the equipment operation. In addition, the structural design of the driving groove 561 can reduce the movement friction, improve the service life of the equipment, and reduce the energy consumption during the operation of the equipment, thereby improving the overall production efficiency.

[0033] The usage method and working principle of this device: When performing the filtration operation, the feed flow rate of the feed pipe 4 needs to be controlled according to the actual filtration situation. This is because too fast a flow rate will enhance the carrying capacity of the fluid for impurities, increase the hydrodynamic force on the impurities, and thus lead to incomplete filtration.

[0034] During the process of controlling the flow rate, the swing of the swing rod 51 can drive the fixed block 52 to move. At this time, the swing rod 51 rotates around the support plate 512 and drives the first movable block 531 to move through the support plate 512. Under the action of the first movable block 531, the linkage rod 53 starts to act, and transmits the acting force to the two cranks 59 through the second movable block 532. The movement of the crank 59 drives the central rod 591 to rotate, and the central rod 591 further drives the movable plate 592 to rotate inside the regulating pipe 42, thereby realizing the control of the fluid flow rate in the regulating pipe 42.

[0035] When the swing rod 51 swings, the connecting frame 54 will also move accordingly. During this process, the connecting frame 54 uses the cooperation of the driving block 541 and the driving groove 561 to apply a force to the lifting sleeve 56, causing the lifting sleeve 56 to slide on the outer surface of the top end of the rotating rod 55. When the lifting sleeve 56 moves up and down, it drives the transmission rod 57 to move synchronously. As the transmission rod 57 moves with the lifting sleeve 56, the stirring rod 58 can be driven to act, causing the stirring rod 58 to swing, thereby realizing the control of the angles of the two stirring rods 58. This causes the stirring angle of the stirring blades 581 to change, increasing the diversity of the stirring methods during filtration, which can not only improve the filtration effect but also further achieve precise filtration of impurities.

[0036] When the first driving motor 2 operates, it can drive the belt transmission assembly 21 to operate. The belt transmission assembly 21 transmits the power to the rotating rod 55, causing the rotating rod 55 to rotate, and at the same time driving the stirring rod 58 and the stirring blades 581 to rotate together. During the continuous production of epoxy paint thinner, this operation helps to improve the filtration effect. During this process, the driving groove 561 and the driving block 541 slide relative to each other, which can not only bear the up and down acting force of the driving block 541 but also will not have movement interference with the driving block 541 during rotation.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
