Description

Technical Field

[0001] This utility model relates to the field of resin processing, and more specifically, to a resin adhesive impurity removal device. Background Technology

[0002] Resins are a class of amorphous organic substances with high molecular weight, relatively complex structure and no definite melting point. They are mostly solid, semi-solid or liquid at room temperature, and can soften and flow when heated. They can break into a shell shape. They are divided into natural resins (such as rosin, amber, etc.) and artificial resins (such as polyethylene, polypropylene epoxy resin and chloroacetic acid resin, etc.).

[0003] Vinyl chloride resin is a thermoplastic resin synthesized from vinyl chloride and vinyl acetate. It softens when heated and hardens when cooled. Due to its excellent adhesion, flexibility, film-forming properties, and chemical resistance, it is widely used in coatings, inks, and other fields. However, during the production of vinyl chloride resin, the resin solution obtained from the reaction vessel may contain unreacted solid particles and metal particles, among other impurities. These impurities directly affect the quality of the resin, therefore, impurity removal is necessary for the vinyl chloride resin solution.

[0004] For example, the authorized utility model patent with application number 202322552674.X discloses a resin adhesive impurity removal device for resin production, including an impurity removal tank. A sealing cover is snapped onto the top of the impurity removal tank. Support rods are fixedly installed on both sides of the bottom end of the sealing cover. Connecting seats are snapped onto the bottom of the two support rods. A filter screen seat is fixedly installed at the bottom between the two connecting seats. A fixing seat is fixedly installed on the outer side of the bottom end of the filter screen seat. A magnetic suction component is snapped onto the inside of the fixing seat.

[0005] However, during the use of the above-mentioned resin adhesive impurity removal device for resin production, due to the viscosity of the resin adhesive, if the adhesive is not disturbed during filtration, it will gradually adhere to the inner wall. After the adhesive solidifies after cooling, it will form new impurities. These impurities accumulate on the filter screen, which can easily lead to a decrease in the filtration effect of the filter screen and make cleaning more troublesome.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] In view of the problems in the related technologies, this utility model proposes a resin adhesive impurity removal device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0008] Therefore, the specific technical solution adopted by this utility model is as follows:

[0009] A resin adhesive impurity removal device includes an impurity removal barrel with a hollow structure; a heating wire arranged around the inner wall and outer shell of the impurity removal barrel for heating the resin adhesive; a control panel located at the bottom outer side of the impurity removal barrel; a hydraulic rod located at the middle outer side of the impurity removal barrel; a stirring assembly located at the top of the impurity removal barrel and connected to the hydraulic rod for stirring the resin adhesive; and a filter plate located inside the impurity removal barrel for filtering the resin adhesive.

[0010] Furthermore, in order to achieve the stirring operation of the resin liquid, the stirring assembly includes a sealing cover set at the top of the impurity removal tank, and the sealing cover has a semi-circular structure. Inside the sealing cover, a first baffle and a second baffle are arranged from top to bottom. A first gear is arranged in the middle of the first baffle, and a second gear is arranged in the middle of the second baffle. A bushing is arranged at the bottom of the second gear. A drive gear that meshes with the first gear and the second gear is arranged on the outside of them. A motor is arranged through the sealing cover at the bottom of the drive gear.

[0011] Furthermore, in order to achieve mixing and wall scraping operations, a mixing element is installed at the bottom end of the first gear through the second baffle. The bottom end of the mixing element passes through the second gear and the bushing in sequence. Bearings are installed between the mixing element and the second gear, and between the bushing and the second baffle. A wall scraping frame is symmetrically arranged on the outside of the bushing. Several wall scraping blades are installed on one side of the wall scraping frame. The wall scraping blades are in close contact with the inner wall of the impurity removal barrel to scrape and clean the inner wall.

[0012] Furthermore, to facilitate easy replacement of the fan blades, the agitator includes an agitator roller located at the bottom of the first gear. A first and second ring are positioned on the outer side of the agitator roller, and fan blades are mounted on the outer sides of both the first and second rings. Several fragmentation blocks are positioned on both sides of the fan blades. The fragmentation blocks are triangular cone-shaped. The first ring has a semi-circular structure, with a first boss at both ends and a second boss at the center of one side of the first boss. Trapezoidal grooves are formed at the top and bottom of the sidewall of the first boss, and first pin holes are formed at the center of the top and bottom of the second boss. The second ring also has a semi-circular structure, with grooves at both ends. A third boss is symmetrically positioned at the top and bottom of the groove. A second pin hole is formed on one side of the third boss, and a trapezoidal tooth block that mates with the trapezoidal groove is positioned on the side of the third boss adjacent to the second pin hole. Several through holes are formed on the outer side of the second ring.

[0013] Furthermore, to facilitate assembly, a pin is provided between the first pin hole and the second pin hole, and the pin and the through hole cooperate with each other.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Heating the impurity removal tank via heating wires maintains the resin solution within a constant temperature range, preventing solidification of the cooled solution inside the tank. This creates a strong bidirectional shearing force on the resin solution, propelling it towards the wall and vertically. A scraper removes adhering resin and impurities from the wall surface, effectively preventing the resin solution from solidifying and forming a skin, thus avoiding the formation of new impurities. Simultaneously, the agitation of the resin solution ensures more even heat exchange within the tank. The well-designed structure allows for quick and easy installation and removal of the fan blades, improving agitation efficiency and reducing worker workload.

[0016] 2. The stirring assembly, with its efficient mixing capabilities and continuous wall scraping, promotes rapid heat exchange of materials throughout the container in three dimensions. The temperature differences between the central region, the wall regions, and the bottom and top are significantly reduced, ensuring temperature uniformity and precision during the reaction or mixing process. Real-time wall scraping effectively prevents resin from solidifying and forming a skin on the high-temperature wall surface. This not only reduces the waste of expensive raw materials but also prevents the skin from peeling off and becoming impurities in the resin, thus affecting product quality and performance.

[0017] 3. By using the first and second rings together, the fan blades can be quickly and efficiently installed and disassembled while ensuring installation stability and firmness. This reduces the workload of workers and the time cost of disassembly, cleaning and maintenance, thereby improving production efficiency. Attached Figure Description

A solenoid valve electrically connected to the control panel 3 is installed inside the outlet 8.

[0030] It should be noted that the heating wire 2 and the motor 508 are electrically connected to the control panel 3. The start command is issued through the human-machine interface (HMI) of the control panel 3. This signal is transmitted from the HMI to the PLC programmable logic controller. After receiving the command, the PLC controls the start, stop, rotation and power of the above-mentioned components. This is existing technology and will not be elaborated on here.

[0031] In one embodiment, the stirring assembly 5 includes a sealing cover 501 disposed at the top of the impurity removal tank 1, and the sealing cover 501 has a semi-circular structure. Inside the sealing cover 501, a first baffle 502 and a second baffle 503 are arranged sequentially from top to bottom. A first gear 504 is disposed in the middle of the first baffle 502, and a second gear 505 is disposed in the middle of the second baffle 503. A bushing 506 is disposed at the bottom of the second gear 505. An active gear 507 is disposed on the outside of the first gear 504 and the second gear 505 to mesh with them. A motor 508 is disposed through the bottom of the active gear 507 and passes through the sealing cover 501.

[0032] A stirring element 509 is disposed at the bottom end of the first gear 504, penetrating the second baffle 503. The bottom end of the stirring element 509 sequentially penetrates the second gear 505 and the bushing 506. Bearings are provided between the stirring element 509 and the second gear 505, and between the bushing 506 and the second baffle 503. A scraping frame 510 is symmetrically arranged on the outer side of the bushing 506. Several scraping blades 511 are provided on one side of the scraping frame 510, and the scraping blades 511 are in close contact with the inner wall of the impurity removal barrel 1 to scrape and clean the inner wall. The stirring element 509 includes a stirring roller 512 disposed at the bottom end of the first gear 504. A first collar 513 and a second collar 514 are disposed on the outer side of the stirring roller 512. Fan blades 515 are disposed on the outer sides of both the first collar 513 and the second collar 514. Several breaking blocks 516 are disposed on both sides of the fan blades 515. The breaking blocks 516 are triangular cone-shaped. The first ring 513 has a semi-circular structure. Both ends of the first ring 513 have a first boss 517, and a second boss 518 is located in the middle of one side of the first boss 517. The top and bottom of the sidewall of the first boss 517 have trapezoidal grooves 519, and the middle of the top and bottom of the second boss 518 have first pin holes 520. The second ring 514 has a semi-circular structure. Both ends of the second ring 514 have grooves 521, and the top and bottom of the grooves 521 have symmetrically arranged third bosses 522. One side of the third boss 522 has a second pin hole 523, and the side of the third boss 522 adjacent to the second pin hole 523 has a trapezoidal tooth block 524 that mates with the trapezoidal groove 519. Several through holes 525 are located on the outer side of the second ring 514. A pin 526 is provided between the first pin hole 520 and the second pin hole 523, and the pin 526 cooperates with the through hole 525 to realize the stirring and wall scraping of the adhesive, and at the same time, the fan blade can be quickly disassembled.

[0033] The working principle of the stirring assembly 5 is as follows: First, the operator starts the motor 508 through the HMI interface of the control panel 3. The output shaft of the motor 508 drives the drive gear 507 to rotate. The rotating drive gear 507 synchronously drives the first gear 504 and the second gear 505 to rotate. At this time, under the drive of the drive gear 507, the first gear 504 and the second gear 505 rotate in opposite directions on the same axis. The rotating first gear 504 drives the stirring roller 512 to rotate, and at the same time drives the fan blade 515 to rotate. The second gear 505 drives the scraper blade 511 on the scraper frame 510 to rotate on the inner wall of the impurity removal tank 1, so that the fan blade 515 and the scraper blade 511 rotate in opposite directions on the same axis. During the stirring process, the crushing blocks 516 on the fan blade 515 crush the solid particles in the adhesive.

[0034] When the first ring 513 and the second ring 514 are fitted onto the stirring roller 512, the first boss 517 is disassembled into the groove 521. Under the action of the pin 526, the first pin hole 520, the second pin hole 523 and the through hole are on the same diameter, thereby aligning the trapezoidal tooth block 524 with the trapezoidal groove 519 and fixing the first ring 513 and the second ring 514 onto the stirring roller 512. When disassembling, the pin 526 can be removed to complete the disassembly.

[0035] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0036] In practical applications, the resin solution to be removed is poured into the impurity removal tank 1 through the inlet 7. Then, the operator starts the heating wire 2 through the control panel 3 to melt the resin solution inside the impurity removal tank 1 (for chloroacetic acid resin, the temperature inside the impurity removal tank 1 is controlled between 75° and 90° during operation by the heating wire 2, and the heating time is one to four hours). Then, the hydraulic rod 4 drives the sealing cover 501 in the stirring assembly 5 to seal and close the impurity removal tank 1, stirring the resin solution inside the impurity removal tank 1. At the same time, the inner wall of the impurity removal tank 1 is scraped off (the working principle of the stirring assembly 5 is as described above). After the resin solution in the impurity removal tank 1 is filtered and removed by the filter plate 6, the operator sends a start command to the solenoid valve through the control panel 3, so that the clean resin solution is discharged through the outlet 8 at the bottom of the impurity removal tank 1.

[0037] After the resin adhesive is completely discharged, when cleaning the remaining impurities in the impurity removal tank 1, the operator lowers the heating temperature of the heating wire 2 via the control panel 3, reducing the temperature inside the impurity removal tank 1 to between 30°C and 40°C (to prevent the remaining adhesive from fusing and solidifying with the impurities during cooling). Then, the operator controls the hydraulic rod 4 to lift the sealing cover 501 upwards, releasing the seal on the impurity removal tank 1. Simultaneously, the scraper blade 511 is lifted out from the top of the impurity removal tank 1. Next, the operator applies high-pressure spray to the inside of the impurity removal tank 1 and the filter plate 6 to clean them. Then, the operator activates the solenoid valve to discharge the wastewater containing the adhesive and impurities through the discharge port 8. After the scraper blade 511 is fully lifted out, the operator uses specialized tools to clean the remaining adhesive and impurities from the scraper blade 511. Simultaneously, the operator can clean and maintain the stirring roller 512 and the fan blade 515.

[0038] In summary, by means of the above-mentioned technical solution of this utility model, the heating wire 2 heats the impurity removal tank 1, keeping the resin liquid within a constant temperature range and preventing the cooled liquid from solidifying inside the tank. The stirring assembly 5 creates a bidirectional strong shearing force on the resin solution inside the tank. The stirring roller 512 and the fan blade 515 push the resin liquid towards the wall and in the vertical direction. The wall scraper 511 generates strong shearing force with the wall, scraping off the resin and impurities attached to the wall, effectively preventing the resin liquid from solidifying into a skin and forming new impurities by staying on the wall for a long time. At the same time, the stirring resin liquid can make the heat exchange more evenly in the impurity removal tank 1, ensuring the uniformity of temperature during the impurity removal process. It also allows for quick and easy installation and disassembly of the fan blade 515, improving the stirring efficiency and reducing the workload of the workers.
