[0015] Compared with the prior art, the present application has the following advantages:

[0016] 1. In the high water-absorbing resin production drying and crushing device, the rotating scraper with an arc-shaped rubber layer is arranged below the sieve plate, which significantly improves the efficiency and uniformity of resin screening. The rotating scraper is driven by a driving device fixed on the side wall of the pulverizer and can rotate on the surface of the sieve plate. The bottom end of the rotating scraper is designed in an arc shape and covered with a soft and wear-resistant arc-shaped rubber layer. This layer not only closely adheres to the surface of the sieve plate, but also effectively removes the resin particles stuck on the sieve plate during rotation, preventing resin accumulation. This design ensures that the resin can smoothly pass through the sieve plate into the material storage drawer, and the substandard resin can also be smoothly blown into the secondary discharging pipe for re-pulverizing.

[0017] 2、The high water-absorbent resin production drying and crushing device, in the design of the rotating scraper, introduces a spring loading system. Specifically, the rotating scraper is connected to the upper fixed frame through a hinge, and a small compression spring is installed near the hinge. When the front end of the scraper is subjected to a large reaction force, the spring will be compressed, causing the front end of the scraper to be slightly raised, thereby avoiding damage to the screen plate caused by hard contact. In addition, the spring loading system allows the scraper to automatically adjust the angle according to different resistance, ensuring that it can maintain the best working state under different working conditions. This adaptive design not only effectively reduces the wear of the screen plate, but also facilitates daily maintenance and inspection. BRIEF DESCRIPTION OF DRAWINGS

In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.

[0031] Please refer to Figure 1 As shown in the drawings, the present embodiment aims to provide a drying and crushing device for high water absorption resin production, which comprises a drying machine 1, a feeding port 2 is arranged at the upper end of the drying machine 1, and the high water absorption resin to be treated is put into the feeding port 2. A discharge pipe 3 is arranged on one side of the feeding port 2, so that the resin after drying can directly enter a crusher 4 for crushing treatment. The crusher 4 is arranged below the discharge pipe 3, and the discharge port 5 of the crusher 4 is located below the corresponding position of the discharge pipe 3, so as to ensure that the resin can be smoothly transferred from the drying machine 1 to the crusher 4.

[0032] As Figure 3 shown, a crushing chamber 7 is arranged inside the crusher 4, and two crushing rollers 12 are arranged in the crushing chamber 7. The crushing rollers 12 are driven by a motor 11 clamped on the side wall of the crusher 4, and can efficiently crush the resin to the required particle size. A flexible sieve plate 28 is arranged below the crushing chamber 7 for screening qualified and unqualified resins. As Figure 4As shown, the resin that does not reach the predetermined particle size will be sent back to the feed inlet 2 for re-drying and crushing by the secondary feeding pipe 6. The centrifugal fan 18 is installed in the secondary feeding pipe 6 to help transport the unqualified resin back to the feed inlet 2. The protective cover 10 is clamped on the secondary feeding pipe 6 outside the centrifugal fan 18 to protect the fan and prevent foreign matter from entering the inside of the secondary feeding pipe 6.

[0033] Two guide blocks 13 are symmetrically arranged on the inside wall of the crusher 4 below the crushing roller 12 to guide the crushed resin to smoothly enter the flexible sieve plate 28 for screening. The design of the guide block 13 ensures that the resin can be evenly distributed and smoothly fall on the flexible sieve plate 28, avoiding uneven accumulation or deviation of the resin when entering the sieve plate.

[0034] In order to prevent the resin from accumulating or being stuck on the flexible sieve plate 28, a set of efficient scraper system is designed. As shown, Figure 2 The cylinder 9 is symmetrically installed on the two side walls of the crusher 4, and its output end is directly fixedly connected to one end of the push plate 16. The push plate 16 includes the upper push plate 14 and the lower scraper 15, so that when the cylinder 9 is started, the lower scraper 15 can be pushed to reciprocate on the surface of the flexible sieve plate 28. The fixed plate 19 is directly fixed above the other end of the lower scraper 15. As shown, Figure 6 One end of the fixed plate 19 is firmly connected with the lower scraper 15, and the other end is provided with a plurality of hole grooves 20. These hole grooves 20 are used to realize the rotating function of the rotating scraper 30. As shown, Figure 7 The upper end of the rotating scraper 30 is provided with a fixed column 21 on both sides, which is rotatably arranged in the hole groove 20, allowing the rotating scraper 30 to automatically adjust the angle according to the resistance, avoiding hard contact to damage the flexible sieve plate 28.

[0035] The bottom end of the rotating scraper 30 is provided with an arc-shaped rubber layer 22 made of soft and wear-resistant material, which can closely fit the surface of the flexible sieve plate 28. The arc-shaped rubber layer 22 not only can effectively remove the resin particles stuck on the flexible sieve plate 28, but also can prevent the flexible sieve plate 28 from being damaged. As shown, Figure 8 One end of the lower scraper 15 is provided with two symmetric first fixed blocks 23, and a first connecting shaft 25 is fixedly arranged between the two first fixed blocks 23. The rotating scraper 30 is provided with two symmetric second fixed blocks 24 at the corresponding end, and a second connecting shaft 26 is fixedly arranged between the two second fixed blocks 24. A tension spring 27 is arranged between the first connecting shaft 25 and the second connecting shaft 26, allowing the rotating scraper 30 to automatically adjust the angle according to the resistance, further protecting the flexible sieve plate 28 from being damaged. As shown, Figure 5As shown, the pushing rubber layer 29 is arranged at the outer end of the rotating scraper 30, which provides additional gripping force and pushing effect when scraping the resin stuck on the flexible screen plate 28, ensuring that the resin can be pushed more effectively to the secondary feeding pipe 6, while reducing the damage to the flexible screen plate 28, further improving the stability and screening efficiency of the system. The soft and wear-resistant properties of the pushing rubber layer 29 enable it to maintain good scraping effect when contacting the resin, while avoiding wear and tear on the flexible screen plate 28.

[0036] When the air cylinder 9 is activated, the lower scraper 15 reciprocates on the surface of the flexible screen plate 28, driving the rotating scraper 30 to work together. Due to the presence of the fixed plate 19 and the hole slot 20 thereon, the rotating scraper 30 can flexibly adjust the angle according to the resin resistance, ensuring that it always contacts the flexible screen plate 28 in the best posture. In addition, the design of the tension spring 27 allows the rotating scraper 30 to slightly lift when encountering greater resistance, thereby reducing the impact force on the flexible screen plate 28 and prolonging the service life of the flexible screen plate 28.

[0037] Through these carefully designed components and their cooperative mechanism, the utility model effectively solves the problem of resin accumulation on the flexible screen plate 28, while protecting the flexible screen plate 28 from damage, significantly improving the continuous operation capability and overall efficiency of the system. This design not only improves the smoothness of the screening process, but also ensures that the substandard resin can smoothly enter the secondary crushing process, ultimately achieving high-quality product output. These improvements work together to ensure efficient and reliable operation of the entire drying and crushing device.

[0038] The secondary feeding pipe 6 has a secondary feeding port 8 at its upper end, which is designed as a horn shape to ensure that the resin can smoothly enter the secondary feeding pipe 6. The secondary feeding port 8 is located at the corresponding position of the upper end of the discharge port 5 and is fixed to the housing of the crusher 4 through appropriate connecting pieces. This design not only increases the inlet area and reduces the risk of resin blockage, but also makes the resin more concentrated when entering the secondary feeding pipe 6, which helps to improve the conveying efficiency.

[0039] The crusher 4 not only improves the crushing efficiency, but also reduces the risk of resin blockage. The storage drawer 17 is arranged at the bottom end of the crusher 4 and is located below the corresponding position of the flexible screen plate 28, which is used to collect the qualified resin screened by the flexible screen plate 28. The storage drawer 17 is provided with a handle to facilitate the operator to take out the collected resin.

[0040] Through these improvements, the utility model discloses realize the effective treatment of high water absorbent resin, improve the quality and uniformity of the recycled resin. Specifically, the rotating scraper 30 with arc-shaped rubber layer 22 effectively removes the accumulated resin on the screen plate, ensuring smooth screening process, while avoiding damage to the screen plate. The spring-loaded system allows the rotating scraper 30 to automatically adjust the angle according to different resistance, further protecting the screen plate and extending its service life. In addition, the centrifugal fan 18 in the secondary discharge pipe 6 ensures that the substandard resin can be smoothly blown into the secondary discharge pipe 6 for further processing, ensuring the quality consistency of the final product. These designs work together to significantly improve the stability and processing efficiency of the system.

[0041] Working principle: high water absorbent resin is put into the dryer 1 through the feed inlet 2 for preliminary drying treatment, and the dried resin enters the pulverizer 4 through the discharge pipe 3. In the pulverizer 4, the resin is first subjected to high-efficiency pulverization by the pulverizing roller 12 driven by the motor 11, and then falls onto the flexible screen plate 28 for screening. The qualified resin passes through the flexible screen plate 28 into the storage drawer 17, while the unqualified resin is left on the flexible screen plate 28. At this time, the air cylinder 9 is started, pushing the lower scraper 15 to reciprocate on the surface of the flexible screen plate 28. The fixed plate 19 is directly fixed above one end of the lower scraper 15, and has hole slots 20 at the other end, and the fixed column 21 of the rotating scraper 30 is rotatably arranged in these hole slots 20, so that the rotating scraper 30 can automatically adjust the angle according to the resistance. The arc-shaped rubber layer 22 at the bottom end of the rotating scraper 30 closely adheres to the surface of the flexible screen plate 28, effectively removing the resin particles stuck on the flexible screen plate 28 and preventing resin accumulation. The tension spring 27 is arranged between the first connecting shaft 25 and the second connecting shaft 26, allowing the rotating scraper 30 to slightly lift when encountering greater resistance, further reducing the impact force on the flexible screen plate 28. The unqualified resin is pushed to the secondary discharge pipe 6 under the action of the rotating scraper 30, and the centrifugal fan 18 in the secondary discharge pipe 6 blows these resins back to the feed inlet 2 for re-drying and pulverization. During the whole process, all components work together to ensure effective screening and secondary pulverization of the resin, improve the continuous operation capacity and overall efficiency of the system, and finally realize high-quality product output.
