Description

Technical Field

[0001] This utility model relates to the field of curing agent processing, specifically to a curing agent impurity removal device. Background Technology

[0002] Curing agents are mixtures that enhance or control the curing reaction. They are commonly used in coatings, adhesives, composite materials, and electronic appliances. During the production and processing, some impurities, such as rust and oil, may remain in the equipment. In addition, raw materials and reaction byproducts may contain some fixed particles. These impurities can interfere with the chemical reaction between the curing agent and the resin. In order to ensure the purity of the curing agent, it is necessary to remove impurities from it.

[0003] CN213529115U discloses a device for removing impurities from a curing agent, comprising: a tank, a feed hopper, and multiple adsorption plates. The lower end of the side wall of the tank has a discharge port; the feed hopper is located above the tank, and its bottom plate has a discharge port, which forms an angle with the horizontal direction.

[0004] The above-mentioned impurity removal device has the effect of increasing the adsorption area of ​​the curing agent. During the filtration process, the filtered impurities are easy to accumulate, affecting the subsequent filtration effect and making it inconvenient to automatically scrape and clean them. Furthermore, after filtration, some curing agent raw materials adhere to the inner wall, causing some material waste and making it inconvenient to clean the entire interior. Utility Model Content

[0024] See Figure 2 Furthermore, the filtration mechanism 3 includes a filter cover 5, which is fixedly installed inside the cylinder 1. A connecting pipe 6 is fixedly installed on the top of the filter cover 5, a motor 7 is installed on the top of the connecting pipe 6, and an inlet pipe 8 is installed on the outside of the connecting pipe 6. A shaft 9 is installed at the bottom of the output shaft of the motor 7 and inside the filter cover 5. Several scrapers 10 are fixedly installed on the outside of the shaft 9. A liquid storage tank 11 is provided between the filter cover 5 and the inner wall of the cylinder 1. A hopper 12 is installed at the bottom of the filter cover 5, and a slag discharge pipe 13 is fixedly installed at the bottom of the hopper 12. A first solenoid valve 14 and a second solenoid valve 15 are respectively installed on the outside of the slag discharge pipe 13.

[0025] The connecting pipe 6 is interconnected with the interior of the filter cover 5. The shaft 9 is fixedly connected to the output shaft of the motor 7. The curing agent enters through the liquid inlet pipe 8 and enters the filter cover 5 through the connecting pipe 6.

[0026] The outer diameter of the filter cover 5 is smaller than the inner diameter of the cylinder 1. Several scrapers 10 are arranged around the outside of the shaft 9. The filter cover 5 filters the impurities in the curing agent. The filtered curing agent enters the storage tank 11 and is discharged through the outlet pipe 2.

[0027] The scraper 10 is inclined around the outside of the shaft 9, and the outer side of the scraper 10 is slidably disposed with respect to the inner wall of the filter cover 5. The shaft 9 drives the scraper 10 to rotate, and the scraper 10 scrapes away the impurities filtered on the inner wall of the filter cover 5.

[0028] Specifically, the filter cover 5 intercepts and filters impurities in the curing agent. The filtered curing agent passes through the filter cover 5 and enters the liquid storage tank 11, and is discharged through the liquid outlet pipe 2 at the bottom. The shaft 9 drives the scraper 10 to rotate, and the scraper 10 scrapes away the impurities filtered on the inner wall of the filter cover 5, so as to facilitate the cleaning of the inner wall of the filter cover 5.

[0029] Example 1

[0030] See Figure 3 Furthermore, based on Embodiment 1, the cleaning mechanism 4 includes a lifting ring 16 and a hydraulic cylinder 17. The hydraulic cylinder 17 is installed on the top of the cylinder 1, and the lifting ring 16 is fixedly installed at the bottom end of the telescopic rod of the hydraulic cylinder 17. Several through slots 18 are provided through the upper and lower parts of the lifting ring 16, and a guide rod 19 is fixedly installed on one side of the inside of the cylinder 1.

[0031] The lifting ring 16 is arranged in a ring shape. The outer diameter of the lifting ring 16 matches the inner diameter of the cylinder 1, and the inner diameter of the lifting ring 16 matches the outer diameter of the filter cover 5. The lifting ring 16 is raised and lowered by the extension and retraction of the extension rod of the hydraulic cylinder 17.

[0032] The guide rod 19 is slidably connected inside the lifting ring 16. The lifting ring 16 slides stably through the guide rod 19 and scrapes off the curing agent adhering to the outer wall of the filter cover 5 and the inner wall of the cylinder 1 through the lifting ring 16.

[0033] Specifically, the lifting ring 16 is driven to slide up and down by the telescopic rod of the hydraulic cylinder 17. The lifting ring 16 scrapes off the curing agent adhering to the outer wall of the filter cover 5 and the inner wall of the cylinder 1 to facilitate internal cleaning.

[0034] In actual operation, the curing agent enters through the liquid inlet pipe 8 and enters the filter cover 5 through the connecting pipe 6 for filtration. The filtered curing agent is discharged through the liquid outlet pipe 2, and the filtered impurities are discharged through the slag discharge pipe 13.

[0035] During filtration, the curing agent enters the filter hood 5, where it intercepts and filters impurities such as solid particles, dust, metal shavings, and catalyst residue. The filtered curing agent passes through the filter hood 5 into the storage tank 11 and is discharged through the outlet pipe 2 at the bottom. By starting the motor 7, the shaft 9 drives the scraper 10 to rotate, scraping away the impurities filtered from the inner wall of the filter hood 5. At this time, the valve body of the first solenoid valve 14 is closed, and the scraped impurities fall and fill the top of the hopper 12 and the slag discharge pipe 13. By closing the valve body of the second solenoid valve 15 and opening the valve body of the first solenoid valve 14, the impurities enter the interior of the slag discharge pipe 13. Then, the valve body of the first solenoid valve 14 is closed, and the valve body of the second solenoid valve 15 is opened to discharge the impurities.

[0036] During cleaning, the lifting ring 16 slides up and down inside the cylinder 1 by extending and retracting the telescopic rod of the hydraulic cylinder 17. The lifting ring 16 slides stably through the guide rod 19. The lifting ring 16 scrapes off the curing agent adhering to the outer wall of the filter cover 5 and the inner wall of the cylinder 1 to facilitate internal cleaning.
