Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of resin processing technology, and more specifically, to a resin impurity removal device. Background Technology

[0002] Traditional resin impurity removal methods and devices have many drawbacks. In terms of filtration, while common mesh filters can intercept some larger particles of impurities, they are not effective at removing tiny impurities, especially those that are close to the size of resin particles. For example, when some traditional mesh filters are used to process resin containing fine particles, the impurities can easily penetrate the mesh, resulting in incomplete removal of impurities and affecting the application of the resin in high-end products. In electronic-grade resins, even a tiny amount of impurities can cause performance failures in electronic products.

[0003] The stirring and impurity removal method also has efficiency issues. In some devices, the stirring components are poorly designed, the stirring range is limited, and it is impossible to ensure that the resin is stirred evenly as a whole. As a result, impurities are difficult to separate from the resin. Furthermore, long-term high-intensity stirring may damage the molecular structure of the resin itself and affect its performance. For some special resins that need to maintain the integrity of specific molecular chains, excessive stirring will reduce their strength and toughness. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a resin impurity removal device, which solves the many drawbacks of traditional resin impurity removal methods and devices in the prior art. In terms of filtration, although common screen filters can intercept some larger particulate impurities, they are not effective for small impurities, especially those with a size close to resin particles. For example, when some traditional screen filters are used to process resin containing fine particulate impurities, the impurities can easily penetrate the screen, resulting in incomplete impurity removal.

[0005] According to one aspect, at least one embodiment of the present disclosure provides a resin impurity removal apparatus, comprising:

[0006] A processing tank, wherein a sealing cap is provided on the processing tank;

[0007] A drive-to-remove-impurity assembly is disposed on the sealing cover;

[0008] A linkage cleaning assembly is disposed inside the processing tank;

[0009] The drive and impurity removal assembly includes a mounting platform disposed on the outer side wall of the processing tank. A lifting rod is disposed on the mounting platform, a linkage block is disposed at the upper end of the lifting rod, a sliding plate is disposed on the side wall of the linkage block, a sliding groove is formed on the outer side wall of the processing tank, the sliding plate is embedded in the sliding groove, a sealing cover is connected to the sliding plate, a drive shaft is disposed on the sealing cover, and a stirring plate is disposed on the drive shaft.

[0010] As a further technical solution, the processing tank is provided with a stirring tank inside, the stirring blade is inserted into the stirring tank, the side wall of the drive shaft is provided with a linkage frame, the lower end of the linkage frame is provided with a scraper, and the scraper is in contact with the inner side wall of the stirring tank.

[0011] As a further technical solution, the linkage cleaning component includes a discharge port, which is located on the bottom surface of the mixing tank. A sealing bottom cover is provided on the discharge port, and a flipping frame is provided at the bottom of the sealing bottom cover. The flipping frame is connected to the mixing tank by a pin.

[0012] As a further technical solution, a filter screen is provided inside the processing tank. The filter screen has an inverted conical structure, and its outer contour is sealed and fitted to the inner wall of the processing tank.

[0013] As a further technical solution, the number of scrapers and the number of stirring blades are the same, and the distribution positions of the scrapers and the stirring blades are the same.

[0014] As a further technical solution, the inner wall of the processing tank is provided with an annular groove, and the outer wall of the mixing tank is provided with a limiting ring, which is embedded in the interior of the annular groove.

[0015] As a further technical solution, a connecting rod is provided on the side wall of the sliding plate, and a mounting plate is provided at the end of the connecting rod, the mounting plate being connected to the drive shaft.

[0016] As a further technical solution, a sealing plug is provided at the bottom of the sealing cover, and the sealing plug is in a sealed fit with the processing tank.

[0017] As a further technical solution, a mounting shaft is provided at the bottom of the drive shaft, and a cleaning plate is provided on the side wall of the mounting shaft.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] In this disclosure, regarding the impurity removal effect, the device achieves efficient impurity removal through multiple synergistic effects. The filter screen adopts an inverted conical structure, which is sealed and fitted to the inner wall of the processing tank, enabling preliminary filtration of the resin and effectively intercepting larger particulate impurities. The drive shaft drives the stirring blade to rotate inside the stirring tank, which can fully stir the resin, allowing impurities to be fully separated from the resin, greatly improving the thoroughness of impurity removal. At the same time, during the stirring process, the scraper at the lower end of the linkage frame is in contact with the inner wall of the stirring tank, which can promptly scrape off the resin and impurities adhering to the tank wall, avoiding the residue of impurities from affecting the subsequent impurity removal effect. This solves the problems of incomplete filtration and low impurity removal efficiency of traditional filter screens, and can meet the stringent requirements for resin purity in high-end fields.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figs. 1-3 As shown, a resin impurity removal device of this disclosure is illustrated, comprising:

[0032] Processing tank 1, with a sealing cover 2 installed on it;

[0033] Drive the impurity removal component 3, which is mounted on the sealing cover 2;

[0034] The linkage cleaning component 4 is installed inside the processing tank 1;

[0035] The drive and impurity removal assembly 3 includes a mounting platform 3-1, which is set on the outer side wall of the processing tank 1. A lifting rod 3-2 is set on the mounting platform 3-1. A connecting block 3-3 is set at the upper end of the lifting rod 3-2. A sliding plate 3-4 is set on the side wall of the connecting block 3-3. A sliding groove 3-5 is opened on the outer side wall of the processing tank 1. The sliding plate 3-4 is embedded in the interior of the sliding groove 3-5. A sealing cover 2 is connected to the sliding plate 3-4. A drive shaft 3-6 is set on the sealing cover 2. A stirring plate 3-7 is set on the drive shaft 3-6.

[0036] The linkage cleaning component 4 includes a discharge port 4-1, which is located on the bottom surface of the mixing tank 3-8. A sealing bottom cover 4-2 is provided on the discharge port 4-1, and a flipping frame 4-3 is provided at the bottom of the sealing bottom cover 4-2. The flipping frame 4-3 is connected to the mixing tank 3-8 by a pin.

[0037] In some examples, a discharge port 4-1 is provided on the bottom surface of the mixing tank 3-8. The size of the discharge port 4-1 should be reasonably designed according to the resin flow rate and discharge speed. A sealing bottom cover 4-2 is installed on the discharge port 4-1. The sealing bottom cover 4-2 can be made of rubber, which has good sealing performance and corrosion resistance. The sealing bottom cover 4-2 is fixed to the discharge port 4-1 by threaded connection or snap-fit ​​connection to ensure a tight seal. A tilting frame 4-3 is installed at the bottom of the sealing bottom cover 4-2. The tilting frame 4-3 is connected to the mixing tank 3-8 by a pin. The pin should be made of high-strength steel to ensure the reliability of the connection. The tilting frame 4-3 can be designed with an adjustable angle. By adjusting the position of the pin or using an angle adjustment device, the tilting frame 4-3 can be tilted at different angles to meet different discharge requirements. When it is necessary to discharge the resin in the mixing tank 3-8, the sealing bottom cover 4-2 is opened. The sealing bottom cover 4-2 rotates around the pin via the tilting frame 4-3 to open the discharge port 4-1, and the resin is discharged from the discharge port 4-1. During the discharge process, the angle of the tilting frame 4-3 can be adjusted as needed to control the discharge speed and flow rate. After the discharge is completed, the sealing bottom cover 4-2 is closed to seal the discharge port 4-1 and prevent impurities from entering.

[0038] The filter screen 4-4 is installed inside the processing tank 1. The filter screen 4-4 is an inverted conical structure, and its outer contour is sealed to the inner wall of the processing tank 1. The sealing between the filter screen 4-4 and the inner wall of the processing tank 1 can be ensured by setting a sealing rubber ring on the edge of the filter screen 4-4 or by using sealant. The filter screen 4-4 can be made of stainless steel wire mesh, and the appropriate mesh size is selected according to the size of the impurities.

[0039] like Figs. 1-3As shown in the figure, this embodiment proposes that the processing tank 1 is provided with a mixing tank 3-8, the mixing blade 3-7 is inserted into the mixing tank 3-8, the side wall of the drive shaft 3-6 is provided with a linkage frame 3-9, the lower end of the linkage frame 3-9 is provided with a scraper 3-10, and the scraper 3-10 is in contact with the inner side wall of the mixing tank 3-8.

[0040] In some examples, the stirring blades 3-7 are inserted into the interior of the mixing tank 3-8. The number and distribution of the stirring blades 3-7 should be designed according to the size of the mixing tank 3-8 and the mixing requirements of the resin. A linkage frame 3-9 is installed on the side wall of the drive shaft 3-6, and a scraper 3-10 is installed at the lower end of the linkage frame 3-9. The scraper 3-10 is in contact with the inner wall of the mixing tank 3-8. The scraper 3-10 can be made of rubber or plastic and has a certain degree of elasticity. It can effectively scrape off the resin impurities attached to the inner wall of the mixing tank 3-8 without damaging the inner wall of the mixing tank 3-8. The number of scrapers 3-10 and the stirring blades 3-7 are the same and the distribution is the same. When the drive shaft 3-6 drives the stirring blades 3-7 to rotate, the linkage frame 3-9 synchronously drives the scraper 3-10 to rotate, thereby cleaning the inner wall of the mixing tank 3-8.

[0041] During the process of the driving shaft 3-6 driving the stirring blade 3-7 to stir the resin, the scraper 3-10 rotates synchronously with the linkage frame 3-9, continuously scraping away resin impurities on the inner wall of the mixing tank 3-8 to prevent the accumulation of impurities from affecting the stirring effect and resin quality. When it is necessary to clean or maintain the mixing tank 3-8, the sealing cover 2 and related components can be lifted by the lifting rod 3-2 to remove the mixing tank 3-8 from the processing tank 1 for subsequent operations.

[0042] For example, such as Fig. 2 As shown, a filter screen 4-4 is installed inside the processing tank 1. The filter screen 4-4 has an inverted conical structure, and its outer contour is sealed and fitted to the inner wall of the processing tank 1.

[0043] In some examples, after the resin enters the processing tank 1, it first passes through the filter screen 4-4, where impurities are intercepted. The preliminarily purified resin then enters the mixing tank 3-8 for further mixing and impurity removal. The filter screen 4-4 is cleaned regularly by removing it from the processing tank 1 and washing it with a high-pressure water gun or using ultrasonic cleaning to remove the attached impurities, thus ensuring the filtration effect of the filter screen 4-4.

[0044] For example, such as Fig. 2 As shown, the number of scraper blades 3-10 and stirring blades 3-7 are the same, and the distribution positions of scraper blades 3-10 and stirring blades 3-7 are the same. The inner side wall of the processing tank 1 has an annular groove 5, and the outer side wall of the stirring tank 3-8 is provided with a limiting ring 6, which is embedded in the annular groove 5.

[0045] In some examples, a mixing tank 3-8 is installed inside the processing tank 1. The outer contour of the mixing tank 3-8 should maintain a certain gap with the inner wall of the processing tank 1 to ensure that the mixing tank 3-8 can rotate freely inside the processing tank 1. An annular groove 5 is opened on the inner wall of the processing tank 1, and a limiting ring 6 is set on the outer wall of the mixing tank 3-8. The limiting ring 6 is embedded in the annular groove 5. Through the cooperation of the limiting ring 6 and the annular groove 5, the axial and radial movement of the mixing tank 3-8 is restricted, while ensuring that the mixing tank 3-8 can rotate around its own axis.

[0046] For example, such as Fig. 2 As shown, a connecting rod 7 is provided on the side wall of the sliding plate 3-4, and a mounting plate 8 is provided at the end of the connecting rod 7. The mounting plate 8 is connected to the drive shaft 3-6.

[0047] In some examples, a connecting rod 7 is installed on the side wall of the sliding plate 3-4, and a mounting plate 8 is installed at the end of the connecting rod 7. The mounting plate 8 is connected to the drive shaft 3-6 by welding or bolting. The connecting rod 7 and the mounting plate 8 serve to transmit power and support the drive shaft 3-6, ensuring the stability of the drive shaft 3-6 during rotation.

[0048] For example, such as Fig. 2 As shown, a sealing plug 9 is provided at the bottom of the sealing cover 2, and the sealing plug 9 is sealed and fitted with the processing tank 1.

[0049] In some examples, a sealing plug 9 is installed at the bottom of the sealing cap 2. The sealing plug 9 can be made of rubber or silicone, which has good elasticity and sealing performance. When the sealing cap 2 is closed, the sealing plug 9 fits tightly with the processing tank 1 to form a good seal and prevent resin leakage and impurities from entering.

[0050] For example, such as Fig. 3 Fig. 3 As shown, a mounting shaft 10 is provided at the bottom of the drive shaft 3-6, and a cleaning substrate 11 is provided on the side wall of the mounting shaft 10.

[0051] In some examples, a mounting shaft 10 is installed at the bottom of the drive shaft 3-6, and a cleaning plate 11 is installed on the side wall of the mounting shaft 10. The cleaning plate 11 can be made of soft brush or rubber scraper material. When the drive shaft 3-6 rotates, the mounting shaft 10 and the cleaning plate 11 rotate accordingly to clean the bottom of the processing tank 1 and prevent resin impurities from accumulating at the bottom.

[0052] During use, resin is added by starting the lifting rod 3-2. The lifting rod 3-2 drives the connecting block 3-3 to rise. The connecting block 3-3 moves upward along the sliding groove 3-5 via the sliding plate 3-4, thereby opening the sealing cover 2. The resin to be purified is then added from the opening of the processing tank 1. The resin first enters the filter screen 4-4. Since the filter screen 4-4 is an inverted conical structure and is sealed to the inner wall of the processing tank 1, the resin passes through the filter screen 4-4 under the action of gravity. Larger particles are intercepted by the filter screen 4-4, achieving preliminary filtration.

[0053] After preliminary filtration, the resin enters the mixing tank 3-8. At this time, the lifting rod 3-2 drives the sealing cover 2 to descend and close. The sealing plug 9 on the sealing cover 2 fits tightly with the processing tank 1 to ensure the sealing of the processing tank 1. Then, the drive device of the drive shaft 3-6 is started, and the drive shaft 3-6 begins to rotate, which drives the stirring blade 3-7 to rotate in the mixing tank 3-8. The stirring blade 3-7 fully stirs the resin, so that the impurities in the resin are separated from the resin, thereby improving the impurity removal effect.

[0054] During the mixing process, the drive shaft 3-6 simultaneously drives the linkage frame 3-9 to rotate, and the scraper 3-10 at the lower end of the linkage frame 3-9 rotates accordingly. Since the scraper 3-10 is in contact with the inner wall of the mixing tank 3-8, the scraper 3-10 can promptly scrape off the resin and impurities adhering to the inner wall of the mixing tank 3-8, preventing their accumulation from affecting the mixing and impurity removal effect, and also avoiding resin waste. In addition, the mounting shaft 10 and the cleaning plate 11 at the bottom of the drive shaft 3-6 also rotate with the drive shaft 3-6 to clean the bottom of the mixing tank 3-8 and prevent impurities from accumulating at the bottom.

[0055] After the resin impurities are removed, the treated resin needs to be discharged. Open the sealing bottom cover 4-2 on the discharge port 4-1 on the bottom surface of the mixing tank 3-8. The sealing bottom cover 4-2 rotates around the pin shaft via the tilting frame 4-3, which opens the discharge port 4-1. The treated resin flows out from the discharge port 4-1. During the discharge process, the discharge speed and flow rate of the resin can be controlled by adjusting the angle of the tilting frame 4-3.

[0056] If cleaning or maintenance of the device is required, the sealing cover 2 can be lifted again by lifting rod 3-2 to remove the mixing tank 3-8 from the processing tank 1. Since the limiting ring 6 on the outer wall of the mixing tank 3-8 is embedded in the annular groove 5 on the inner wall of the processing tank 1, the removal process is simple and convenient. At the same time, the filter screen 4-4 can be removed and cleaned to ensure the subsequent filtration effect.

[0057] Throughout the entire process, the components work together to effectively remove impurities from the resin through processes such as filtration, stirring, cleaning, and discharging. The operation is convenient and can effectively improve the efficiency and quality of resin impurity removal.
