Description

Technical Field

[0001] The utility model relates to the technical field of phenolic resin production, in particular to a quick dryer for phenolic reinforced resin. Background Art

[0002] Currently, most dryers for producing phenolic reinforcing resins on the market use spray drying. The principle is to bring the atomized material into contact with hot air in a drying tower, and the water is quickly vaporized to obtain a dry product. This method can directly dry solutions and emulsions into powder or granular products, eliminating the evaporation, crushing and other processes.

[0003] In the prior art, the liquid sprayed from the feed pipe nozzle of the centrifugal atomizer is relatively coarse, resulting in poor atomization effect and low efficiency. When the feeding speed increases, the liquid column is likely to be directly sprayed onto the inner wall of the drying tower, which limits the feeding speed and easily causes the liquid to stick to the wall and waste. At the same time, the existing drying equipment also has problems such as inconvenient observation, low discharge efficiency, and poor effect.

[0004] An existing patent (publication number: CN209464615U) discloses a drying device for producing sulfonated phenolic resin. This utility model relates to a drying device for producing sulfonated phenolic resin, characterized by comprising a feeding pump, an air heater, a hot air distributor, a high-speed centrifugal atomizer, and a drying tower. The feed pipe of the high-speed centrifugal atomizer is provided with a duckbill nozzle, a wind lock is provided between the drying tower and the discharge port, and a visual window is provided in the middle of the drying tower. This utility model provides a drying device for producing sulfonated phenolic resin with excellent atomization effect, high efficiency, reduced material wall adhesion, easy observation, stable discharge, and high efficiency.

[0005] In response to the above problems, existing patents have provided solutions. However, although a duckbill nozzle is provided in the equipment in the above patent to improve the atomization effect and reduce the phenomenon of material sticking to the wall, in actual production, some products will inevitably adhere to the inner wall of the drying tower. As time goes by, the accumulated materials will still cause waste by sticking to the wall, affecting production efficiency and cost control. At the same time, the visual window set in the middle of the drying tower will be contaminated by the material during long-term use, and no cleaning structure is provided, which will gradually affect the observation effect.

[0006] Therefore, a quick dryer for phenolic reinforced resin is proposed. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6 , this utility model provides a technical solution:

[0029] A rapid dryer for phenolic reinforced resin includes a drying tower 1. The bottom of the drying tower 1 is connected to a blower 2. The bottom of the blower 2 is connected to a discharge pipe 3. The top of the drying tower 1 is connected to a hot air distributor 4. A hot air structure 5 is provided on the left side of the drying tower 1. The right side of the hot air structure 5 is connected to the left side of the hot air distributor 4. An atomizing spray structure 6 is provided on the top of the drying tower 1. The bottom of the atomizing spray structure 6 is located on the top side of the drying tower 1. A scraping mechanism 7 is provided inside the drying tower 1. A hole slot 8 is opened on the front side of the drying tower 1. A perspective plate 9 is provided inside the hole slot 8. A cleaning component 10 is provided on the inside of the perspective plate 9. The left side of the cleaning component 10 is connected to the hot air structure 5.

[0030] The scraping mechanism 7 includes a double support rod 701 bolted to the bottom side of the drying tower 1, the top of the double support rod 701 is fixedly connected to a shell 702, a motor 703 is arranged inside the shell 702, the output end of the motor 703 passes through the top side of the shell 702, the output end of the motor 703 is bolted to a shaft rod 704, the outer side of the shaft rod 704 is bolted to a connecting rod 705, the outer side of the connecting rod 705 is fixedly connected to a scraper rod 706, the outer side of the scraper rod 706 is bolted to a scraper pad 707, and the outer side of the scraper pad 707 is in contact with the inner wall of the drying tower 1.

[0031] In this embodiment: by providing a scraping mechanism 7, the motor 703 can be used to drive the shaft 704 to rotate, thereby driving the connecting rod 705 and the scraping rod 706 to rotate, so that the scraping pad 707 is closely attached to the inner wall of the drying tower 1 to perform a scraping operation, and the material adhering to the inner wall is cleaned in time, effectively avoiding the problem of wall sticking waste caused by material accumulation, and ensuring the stability of production efficiency and cost control. At the same time, by providing a cleaning component 10 and connecting it to the hot air structure 5, the perspective plate 9 is cleaned with the help of power or related media provided by the hot air structure 5, ensuring the transparency of the perspective plate 9, so that the operator can clearly observe the internal situation of the drying tower 1, thereby improving the controllability and safety of the production process, thereby improving the working performance and practicality of the phenolic reinforced resin rapid dryer as a whole.

[0032] Specifically, such as Figure 4 As shown, the cleaning assembly 10 includes a three-way pipe 1001 connected to the front side of the perspective plate 9, and the rear side of the three-way pipe 1001 passes through the front side of the perspective plate 9.

[0033] Specifically, such as Figure 4 As shown, the rear side of the three-way pipe 1001 is connected to the elastic tube 1002, and the bottom of the elastic tube 1002 is connected to the scraper plate 1003. The scraper plate 1003 is located inside the hole groove 8. An electric push-pull rod 1004 is provided on the bottom side of the hole groove 8. The telescopic end of the electric push-pull rod 1004 is bolted to the bottom of the scraper plate 1003.

[0034] Specifically, such as Figure 4 As shown, the rear side of the left side of the three-way pipe 1001 is connected to the regulating valve 1005 , and the rear side of the regulating valve 1005 is connected to the front side of the hot air structure 5 .

[0035] In this embodiment, the hot air is passed through the hot air structure 5 and enters the three-way pipe 1001 through the regulating valve 1005. The regulating valve 1005 can control the flow rate and pressure of the hot air to ensure that the amount of hot air entering the cleaning component 10 is appropriate. When it is necessary to clean the perspective plate 9, the regulating valve 1005 is opened and the hot air is allowed to enter the subsequent pipeline. After passing through the three-way pipe 1001, the hot air enters the elastic tube 1002. The elastic tube 1002 has a certain degree of flexibility and can adapt to the needs of different positions and angles. The hot air enters the scraping plate 1003 from the bottom of the elastic tube 1002 and then The electric push-pull rod 1004 works, and its telescopic end pushes or pulls the scraper plate 1003. The scraper plate 1003 moves up and down in the hole groove 8. Hot air is ejected from the scraper plate 1003 to blow and scrape the perspective plate 9. The movement of the scraper plate 1003 can cover the entire perspective plate 9 area to ensure comprehensive cleaning. Under the blowing action of the hot air, the material particles attached to the perspective plate 9 are blown away. At the same time, the scraping action of the scraper plate 1003 further removes stubborn stains, so that the perspective plate 9 remains clear, so that the operator can observe the situation inside the drying tower 1 at any time.

[0036] Specifically, such as Figure 5 As shown, the hot air structure 5 includes a fan 501 arranged on the left side of the drying tower 1, and an electric heating tube 502 is arranged on the rear side of the fan 501. The bottom of the electric heating tube 502 is connected to the output end of the fan 501.

[0037] Specifically, such as Figure 5 As shown, the bottom of the electric heating tube 502 is connected to an air supply pipe 503 , the right side of the air supply pipe 503 is connected to the left side of the hot air distributor 4 , and the front side of the air supply pipe 503 is connected to the rear side of the regulating valve 1005 .

[0038] In this embodiment: after the fan 501 is started, the outside air is sucked in and transported backward. The fan 501 provides the power for air flow to ensure that there is enough air to enter the subsequent heating link. After the air enters the electric heating cylinder 502, the heating element in the electric heating cylinder 502 is energized and heated to heat the air. The electric heating cylinder 502 can quickly heat the air to the set temperature to meet the hot air temperature requirements of the drying process. The heated hot air is transported to the hot air distributor 4 through the air delivery pipe 503. The hot air distributor 4 evenly distributes the hot air into the drying tower 1, causing it to rotate spirally downward and enter the bottom of the drying tower 1, providing uniform and stable heat for the drying of the material.

[0039] Specifically, such as Figure 6 As shown, the atomization spraying structure 6 includes a high-speed centrifugal atomizer 601 arranged on the top of the drying tower 1, and the top of the high-speed centrifugal atomizer 601 is connected to a feed pipe 602.

[0040] Specifically, such as Figure 6As shown, the bottom of the high-speed centrifugal atomizer 601 is connected to a duckbill nozzle 603 , and the duckbill nozzle 603 is located on the top side of the drying tower 1 .

[0041] In this embodiment, the material delivered by the feeding pump and other devices is delivered to the high-speed centrifugal atomizer 601 through the feed pipe 602. The high-speed centrifugal atomizer 601 uses the centrifugal force of high-speed rotation to disperse the material into evenly distributed tiny droplets. The duckbill nozzle 603 at the bottom of the atomizer allows the material to be ejected in a specific shape and angle. The design of the duckbill nozzle 603 helps to improve the atomization effect, allowing the material to be more widely exposed to the hot air, thereby achieving rapid vaporization and drying. After the material is atomized, it is fully mixed with the hot air, and the water is quickly evaporated in the drying tower 1 to be dried into a powder product.

[0042] Working principle: During the use of the phenolic reinforced resin rapid dryer, the outside air is sucked in by starting the fan 501. After the air enters the electric heating cylinder 502, it is quickly heated to an appropriate temperature by the heating element. The heated hot air is transported to the hot air distributor 4 through the air duct 503. The hot air distributor 4 evenly distributes the hot air into the drying tower 1 and makes it rotate spirally downward into the bottom of the drying tower 1, providing a stable and uniform heat environment for material drying. At the same time, the material is transported to the feed pipe 602 through the feeding pump and then to the high-speed centrifugal atomizer 601. Under the action of the high-speed centrifugal atomizer 601, it is dispersed into tiny droplets and sprayed out through the duckbill nozzle 603. After full contact with the hot air, it is quickly vaporized and dried into a powder product. Turning off the fan 2 controls the smooth unloading of the material after the drying is completed and discharged through the discharge pipe 3. During the drying process, in order to solve the problem of material sticking to the wall, the motor 703 inside the shell 702 on the double support rod 701 on the bottom side of the drying tower 1 is started. The output end 703 drives the shaft 704 to rotate, and the connecting rod 705 and the scraper 706 on the shaft 704 rotate accordingly. The scraper pad 707 on the outside of the scraper 706 contacts the inner wall of the drying tower 1. As the scraper 706 rotates, the scraper pad 707 scrapes off the material adhering to the inner wall of the drying tower 1, avoiding the waste of material adhering to the wall caused by accumulation, ensuring production efficiency and cost control, and regularly cleaning and maintaining the perspective plate 9 on the front side of the drying tower 1. Hot air is passed from the air duct 503 through the regulating valve 100 5 enters the three-way pipe 1001, and then reaches the scraper plate 1003 through the elastic tube 1002. When cleaning is required, the electric push-pull rod 1004 works, pushing or pulling the scraper plate 1003 to move up and down in the hole slot 8. Hot air is ejected from the scraper plate 1003 to blow and scrape the perspective plate 9 to remove attached material particles and other stains, ensuring that the perspective plate 9 always remains clear, so that the operator can observe the drying situation inside the drying tower 1 at any time and realize effective monitoring of the entire drying process.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
