Description

Technical Field

[0001] This utility model relates to the technical field of rubber polymers, specifically to a solvent removal device for rubber polymer production. Background Technology

[0002] The rubber polymer coagulation process is a process that uses hot water as a carrier to heat the polymerized rubber liquid in the aqueous phase, and removes and recovers the solvent from the liquid through evaporation. It is usually called the water separation method.

[0003] Current hydrochemical rubber coagulation processes typically employ three- or four-reactor coagulation. Multi-reactor coagulation saves steam and improves solvent removal efficiency. In the first coagulation reactor, the rubber solution is dispersed in hot water as droplets under the influence of steam and mechanical stirring. The solvent in the solution evaporates from the droplets upon heating, turning them into solid rubber particles that precipitate out of the solution. The vaporized solvent and steam are discharged from the top of the first coagulation reactor. The rubber particles and water discharged from the bottom of the first reactor are then further removed through evaporation and low-pressure flash evaporation in subsequent coagulation reactors to remove trace amounts of solvent oil.

[0004] However, the above technical solution has the following shortcomings: Since most of the solvent vaporizes in the first condenser, a large amount of gaseous solvent and water vapor are discharged from the top of the reactor. The vaporized solvent and water vapor will carry some fine rubber particles or foam. Although installing a filter on the gas phase pipeline at the top of the condenser can remove particles and foam in the gas phase and prevent fine particles from adhering to subsequent equipment and affecting equipment operation, the large number of fine particles can easily clog the filter. Regular shutdowns for cleaning or maintenance are required. The operation cycle of a conventional filter is generally one month, which affects production efficiency.

[0005] Environmental requirements: Volatile organic compounds (VOCs) are generated during solvent removal, causing environmental pollution. Current environmental regulations strictly limit VOC emissions, necessitating effective measures to reduce emissions. Furthermore, the wastewater generated during solvent removal contains harmful substances and requires proper treatment to meet environmental standards.

[0006] Safety Requirements: Solvent removal processes are typically carried out under high temperature and high pressure conditions, posing certain safety risks. Appropriate safety measures, such as pressure monitoring, temperature control, and emergency pressure relief devices, are required to ensure production safety.

[0007] Economic Costs: While multi-reactor condensation can save steam, overall energy consumption remains high, necessitating optimization of energy efficiency to reduce production costs. Furthermore, frequent shutdowns due to filter clogging increase maintenance costs and the risk of production interruptions.

[0008] Production efficiency: Frequent downtime caused by filter clogging severely impacts the continuity and stability of production, reducing overall production efficiency. Existing technology is relatively complex to operate, requiring skilled operators and increasing labor costs.

[0009] Therefore, it is essential to design solvent removal equipment for rubber polymer production. Utility Model Content

[0010] The purpose of this invention is to provide a solvent removal device for rubber polymer production, so as to solve the problems mentioned in the background art.

[0011] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a solvent removal device for rubber polymer production, including a coagulation vessel. A filter screen is fixedly connected to the upper part of the coagulation vessel. A rotating hole is vertically opened inside the filter screen. A rotating rod is rotatably connected inside the rotating hole. A drive motor is fixedly connected above the rotating rod, passing through the top of the coagulation vessel. A cleaning mechanism is installed outside the rotating rod and below the filter screen. The cleaning mechanism includes a cleaning plate. A sliding hole is vertically opened inside the cleaning plate, and the rotating rod slides within the sliding hole. The sliding hole is connected to a sliding mechanism with a locking mechanism on its side. A first slot is opened above the cleaning plate, and a brush plate is installed in the first slot. The brush plate is tightly attached to the filter screen. Two stirring rods are fixedly connected to the outside of the rotating rod and at the lower end of the cleaning mechanism. A glue inlet is fixedly connected to the left side of the coagulation vessel, a hot water inlet is fixedly connected to the right side of the coagulation vessel, a gas outlet is fixedly connected to the upper left side of the coagulation vessel, a steam inlet is fixedly connected to the rear side of the coagulation vessel, and a colloid water outlet is fixedly connected to the lower end of the coagulation vessel.

[0012] Further explanation regarding the addition of the aforementioned adhesive and hot water: the adhesive is introduced into the coagulation vessel through the adhesive inlet, and the hot water is introduced into the coagulation vessel through the hot water inlet.

[0013] Further explanation of the above stirring and heating process: The drive motor is started, which drives the rotating rod and two stirring rods to rotate and stir. The adhesive solution, under the action of hot water in the coagulation vessel, disperses into droplets in the hot water. During the stirring process, steam is introduced, and some of the steam condenses and releases latent heat to heat the hot water. The heat is transferred to the adhesive particles through the hot water. At this time, the solvent, monomers, and other components in the droplet-shaped adhesive solution vaporize upon heating, and the solvent gas is discharged upwards by the steam in a certain proportion.

[0014] Further explanation of the above filtration and cleaning process: Vaporized solvent and water vapor pass through the filter screen. Because the mesh size of the filter screen is smaller than the size of fine colloidal particles, the fine colloidal particles in the solvent gas are isolated on the lower surface of the filter screen. After the fine colloidal particles accumulate on the lower surface of the filter screen, the brush plate in the cleaning mechanism brushes the lower surface of the filter screen as the rotating rod rotates, preventing the fine colloidal particles in the solvent gas from accumulating and clogging the filter screen.

[0015] According to the above technical solution, the locking and fixing mechanism includes two L-shaped rods. Two L-shaped grooves are symmetrically opened inside the cleaning plate near the sliding hole end. The two L-shaped rods are slidably installed in the two L-shaped grooves. A first telescopic spring is fixedly connected to the L-shaped rod. The telescopic end of the first telescopic spring is fixedly connected to the inner wall of the L-shaped groove. Two locking slots are opened on the side wall of the rotating rod near the two L-shaped grooves. The two L-shaped rods pass through the L-shaped grooves and cooperate with the two locking slots.

[0016] According to the above technical solution, two second slots are symmetrically opened at both ends of the first slot. A second telescopic spring is fixedly connected inside the second slot. A round-headed locking block is fixedly connected to the telescopic end of the second telescopic spring. Semicircular slots are symmetrically opened at both ends of the paint plate. The round-headed end of the round-headed locking block cooperates with the semicircular slot.

[0017] According to the above technical solution, the two sides of the round-headed card block are symmetrically fixedly connected with limiting blocks, and the two sides of the second slot are symmetrically opened with limiting grooves, and the limiting blocks are slidably connected in the limiting grooves.

[0018] According to the above technical solution, a disc is fixedly connected to the outside of the rotating rod and between the cleaning mechanism and the stirring rod. The end of the disc is located directly below the hot water inlet. Multiple water holes are opened inside the disc, and multiple water grooves are opened on the upper surface of the disc.

[0019] According to the above technical solution, a sliding groove is opened on the side of the colloid water outlet, a baffle is slidably connected in the sliding groove, and a pull handle is fixedly connected to the right side of the baffle.

[0020] According to the above technical solution, a discharge ramp is fixedly connected to the bottom of the coagulation vessel, and the discharge ramp is installed in a ring shape.

[0021] Further explanation of the above discharge process: The treated granules and water are discharged through the granule-water outlet, and the baffle in the sliding trough can control the opening and closing of the discharge.

[0022] According to the above technical solution, three support legs are uniformly fixedly installed at the lower end of the coagulation vessel, and a base plate is fixedly connected to the bottom of the three support legs.

[0023] According to the above technical solution, an observation port is installed at the front of the condensation vessel, and an observation window is fixedly installed inside the observation port by fastening bolts.

[0024] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0025] In using this device, the adhesive is introduced into the coagulation vessel through the adhesive inlet and hot water is introduced into the coagulation vessel through the hot water inlet. The drive motor is then started, driving the rotating rod and two stirring rods to rotate and stir. The adhesive, under the influence of the hot water in the coagulation vessel, disperses into droplets. During stirring, steam is introduced, and some of the steam condenses and releases latent heat to heat the hot water. This heat is transferred to the adhesive particles. At this time, the solvent and monomers in the droplet-shaped adhesive vaporize upon heating. The solvent gas is discharged upwards by the steam in a certain proportion. A filter screen is provided; because the mesh size of the filter screen is smaller than the size of the fine adhesive particles, the vaporized solvent and steam pass through the filter screen, isolating the fine adhesive particles in the solvent gas on the lower surface of the filter screen. After the fine adhesive particles accumulate on the lower surface of the filter screen, the brush plate in the cleaning mechanism brushes the lower surface of the filter screen as the rotating rod rotates, preventing the accumulation of fine adhesive particles in the solvent gas from clogging the filter screen. After using this device, the filter clogging frequency is reduced to 1 / 3 of the original. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figure 1-6This utility model provides a technical solution: a solvent removal device for rubber polymer production, including a coagulation vessel 1. A filter screen 2 is fixedly connected to the upper part of the coagulation vessel 1. A rotating hole 3 is vertically opened inside the filter screen 2. A rotating rod 4 is rotatably connected inside the rotating hole 3. A drive motor 5 is fixedly connected above the rotating rod 4, passing through the top of the coagulation vessel 1. A cleaning mechanism is installed outside the rotating rod 4 and below the filter screen 2. The cleaning mechanism includes a cleaning plate 7. A sliding hole 8 is vertically opened inside the cleaning plate 7. The rotating rod 4 is mounted on the sliding hole 8. The sliding connection is made within the movable hole 8. A locking mechanism is installed on the side of the sliding hole 8. A first slot 10 is opened above the cleaning plate 7, and a brush plate 11 is installed in the first slot 10. The top of the brush plate 11 is tightly fitted to the filter screen 2. Two stirring rods 12 are fixedly connected to the outside of the rotating rod 4 and at the lower end of the cleaning mechanism. A glue inlet 13 is fixedly connected to the left side of the coagulation vessel 1, and a hot water inlet 14 is fixedly connected to the right side of the coagulation vessel 1. A gas phase outlet 15 is fixedly connected to the upper left side of the coagulation vessel 1. The rear of the coagulation vessel 1... A steam inlet 16 is fixedly connected to the side of the coagulation vessel 1, and a colloid water outlet 17 is fixedly connected to the lower end of the coagulation vessel 1. When using this device, colloid is introduced into the coagulation vessel 1 through the colloid inlet 13, and hot water is introduced into the coagulation vessel 1 through the hot water inlet 14. Then, the drive motor 5 is started, which drives the rotating rod 4 and the two stirring rods 12 to rotate and stir. The colloid is dispersed into droplets in the hot water within the coagulation vessel 1 under the action of the hot water. During the stirring process, steam is introduced, and the latent heat released by the condensation of some of the steam is used to heat the hot water. The heat is then transferred to the heat exchanger. Water is transferred to the adhesive particles. At this time, the solvent, monomers and other components in the droplet-shaped adhesive liquid are vaporized by heat. The solvent gas is discharged upward by water vapor in a certain proportion. It passes through a filter screen 2. Because the mesh size of the filter screen 2 is smaller than the size of the fine adhesive particles, the vaporized solvent and water vapor pass through the filter screen 2 and isolate the fine adhesive particles in the solvent gas on the lower surface of the filter screen 2. After the fine adhesive particles accumulate on the lower surface of the filter screen 2, the brush plate 11 in the cleaning mechanism brushes the lower surface of the filter screen 2 with the rotation of the rotating rod 4 to prevent the accumulation of fine adhesive particles in the solvent gas from clogging the filter screen 2.

[0036] according to Figure 5As shown, the locking mechanism includes two L-shaped rods 18. Two L-shaped grooves 19 are symmetrically opened inside the cleaning plate 7 near the sliding hole 8. The two L-shaped rods 18 are slidably installed within the two L-shaped grooves 19. A first telescopic spring 20 is fixedly connected to each L-shaped rod 18. The telescopic end of the first telescopic spring 20 is fixedly connected to the inner wall of the L-shaped groove 19. Two slots 21 are opened on the side wall of the rotating rod 4 near the two L-shaped grooves 19. The two L-shaped rods 18 pass through the L-shaped grooves 19 and engage with the two slots 21. By using the locking mechanism, the L-shaped rods 18 within the locking mechanism are moved out of the two slots 21, allowing the cleaning plate 7 to be moved downwards to replace the paint plate 11. After replacement, the cleaning plate 7 is reset, and the first telescopic spring 20 pushes the L-shaped rods 18 to engage with the slots 21, thus fixing the cleaning plate 7 for reuse.

[0037] according to Figure 5 As shown, two second slots 22 are symmetrically opened at both ends of the first slot 10. A second telescopic spring 23 is fixedly connected inside the second slot 22. A round-headed locking block 24 is fixedly connected to the telescopic end of the second telescopic spring 23. Semicircular slots 25 are symmetrically opened at both ends of the paint plate 11. The round-headed end of the round-headed locking block 24 cooperates with the semicircular slot 25. By setting the second telescopic spring 23, the second telescopic spring 23 pushes the round-headed end of the round-headed locking block 24 to cooperate with the semicircular slot 25, so that the paint plate 11 can be fixed. When it is necessary to disassemble, simply pull the paint plate 11 upward, the round-headed locking block 24 compresses the second telescopic spring 23, and the round-headed locking block 24 and the semicircular slot 25 are offset from each other, so that the paint plate 11 can be disassembled.

[0038] according to Figure 5 As shown, the two sides of the round head block 24 are symmetrically fixedly connected with limit blocks 26, and the two sides of the second slot 22 are symmetrically opened with limit grooves 27. The limit blocks 26 are slidably connected in the limit grooves 27. By setting the limit blocks 26 and the limit grooves 27, the round head block 24 is limited.

[0039] according to Figure 2 As shown, a disc 28 is fixedly connected to the outside of the rotating rod 4 and between the cleaning mechanism and the stirring rod 12. The end of the disc 28 is located directly below the hot water inlet 14. The disc 28 has multiple water holes 29 inside and multiple water channels 30 on its upper surface. By setting up the disc 28, and having multiple water holes 29 inside and multiple water channels 30 on its upper surface, when hot water is introduced into the coagulation vessel 1, the hot water is dispersed through the multiple water holes 29 and multiple water channels 30, so that the hot water comes into more complete contact with the adhesive.

[0040] according to Figure 3 As shown, a sliding groove 31 is opened on the side of the colloid water outlet 17. A baffle 32 is slidably connected in the sliding groove 31. A pull handle 33 is fixedly connected to the right side of the baffle 32. By setting the baffle 32, the colloid water outlet 17 can be controlled. When it is necessary to discharge the finally separated colloids and hot water, simply pull the pull handle 33 to slide the baffle 32 out of the colloid water outlet 17 to discharge the material.

[0041] according to Figure 3 As shown, a discharge ramp 34 is fixedly connected to the bottom of the coagulation vessel 1. The discharge ramp 34 is installed in a ring shape. By setting the discharge ramp 34, the final separated colloid particles and hot water are prevented from remaining inside the coagulation vessel 1 after being discharged.

[0042] according to Figure 3 As shown, three support legs 35 are evenly fixedly installed at the lower end of the coagulation vessel 1, and a base plate 36 is fixedly connected below the three support legs 35. The three support legs 35 and the base plate 36 can provide stable support for the coagulation vessel 1.

[0043] according to Figure 1 As shown, an observation port 37 is installed in front of the coagulation vessel 1. An observation window 38 is fixedly installed in the observation port 37 by fastening bolts. By setting the observation window 38, the reaction inside the coagulation vessel 1 can be observed. The observation window 38 is detachable. When it is disassembled, the inside of the coagulation vessel 1 can be cleaned or the paint plate 11 can be replaced.

[0044] In using this invention, the adhesive is introduced into the coagulation vessel 1 through the adhesive inlet 13, and hot water is introduced into the coagulation vessel 1 through the hot water inlet 14. Then, the drive motor 5 is started, which drives the rotating rod 4 and the two stirring rods 12 to rotate and stir. Under the action of the hot water in the coagulation vessel 1, the adhesive is dispersed into droplets in the hot water. During the stirring process, water vapor is introduced, and the latent heat released by the condensation of some of the steam is used to heat the hot water. The heat is transferred to the adhesive particles through the hot water. At this time, the solvent, monomers and other components in the droplet-shaped adhesive are vaporized by the heat. The solvent gas is discharged upward by the water vapor in a certain proportion. Because the mesh size of the filter screen 2 is smaller than the size of the fine adhesive particles, the vaporized solvent is discharged upward. Water vapor passes through filter screen 2, isolating fine particles in the solvent gas on the lower surface of filter screen 2. After the fine particles accumulate on the lower surface of filter screen 2, the brush plate 11 in the cleaning mechanism brushes the lower surface of filter screen 2 as the rotating rod 4 rotates, preventing the fine particles in the solvent gas from accumulating and clogging the filter screen 2. A locking mechanism is provided; by moving the L-shaped rod 18 in the locking mechanism, the L-shaped rod 18 moves out of the two slots 21, allowing the cleaning plate 7 to be moved downwards to replace the brush plate 11. After replacement, the cleaning plate 7 is reset, and the first telescopic spring 20 pushes the L-shaped rod 18 to engage with the slots 21, thus fixing the cleaning plate 7. A second telescopic mechanism is also provided. Spring 23, the second telescopic spring 23 pushes the round end of the round head block 24 to cooperate with the semi-circular groove 25, which can fix the paint plate 11. When disassembly is required, simply pull the paint plate 11 upwards, the round head block 24 compresses the second telescopic spring 23, the round head block 24 and the semi-circular groove 25 are offset from each other, and the paint plate 1 can be disassembled. By setting a disc 28, and the disc 28 having multiple water holes 29 inside and multiple water channels 30 on the upper surface of the disc 28, when hot water is introduced into the coagulation vessel 1, the hot water is dispersed through the multiple water holes 29 and multiple water channels 30, so that the hot water and the adhesive come into more complete contact. By setting a baffle 32 The device can control the outlet 17 for the colloid and water. When it is necessary to discharge the final separated colloid and hot water, simply pull the handle 33 to slide the baffle 32 out of the outlet 17 for discharge. The discharge ramp 34 prevents the final separated colloid and hot water from remaining inside the coagulation vessel 1 after discharge. The observation window 38 allows observation of the reaction inside the coagulation vessel 1. The observation window 38 is detachable, allowing for cleaning of the inside of the coagulation vessel 1 or replacement of the paint plate 11. All components of this device are general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
