Description

Technical Field

[0001] This utility model relates to the field of resin waste liquid treatment technology, specifically to a device for recycling resin regeneration waste liquid. Background Technology

[0002] Resins are an important class of organic polymer materials. Common resins include polyester resins and epoxy resins. After repeated use, the performance of resins gradually declines, so they need to be regenerated to restore their activity. However, the regeneration process generates a large amount of resin waste liquid. At present, the recycling and treatment of resin waste liquid mainly relies on solid-liquid separation technology. Existing recycling devices mostly use a single filter screen for physical filtration. Although it can remove larger particles, it is difficult to effectively intercept fine particles and colloidal substances due to limited filtration precision. These residual micro-impurities will lead to insufficient purity of the recycled liquid, affecting the subsequent regeneration effect of resins or their direct reuse performance.

[0003] As disclosed in the prior art, Chinese utility model publication CN218357807U discloses a waste liquid recycling device for polyester resin production. This utility model includes a silo body with a feed inlet on the top wall, a movably mounted filter plate inside the silo body, and a guide plate on the inner side wall of the silo body. In the above structure, the waste liquid is filtered by a single filter plate. In practical applications, it can only remove larger particles and is difficult to effectively intercept fine particles and colloidal substances, resulting in insufficient purity of the recycled liquid. This makes it difficult to meet the recycling requirements of resin regeneration waste liquid, which suffers from the problem of limited filtration accuracy of a single filter screen. Therefore, we need to propose a recycling device for resin regeneration waste liquid. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A device for recycling resin regeneration waste liquid includes: a recycling tank 1; a sealing cover 2 disposed on the top of the recycling tank 1; a support ring 3 fixedly installed inside the recycling tank 1; and a multi-stage filtration mechanism 4 for performing multi-stage filtration of the waste liquid, the multi-stage filtration mechanism 4 being installed at the bottom of the sealing cover 2 and located at the top of the support ring 3.

[0026] Through the coordinated arrangement of the recovery tank 1, sealing cover 2, support ring 3, and multi-stage filtration mechanism 4, the recovery tank 1 provides a closed space for waste liquid treatment, the sealing cover 2 ensures the airtightness of the treatment environment and avoids external impurities from contaminating it, and the support ring 3 provides stable support for the multi-stage filtration mechanism 4, ensuring the stability of the filtration process. The multi-stage filtration mechanism 4 can perform graded filtration of impurities of different particle sizes in the resin regeneration waste liquid, solving the problem of poor interception effect of traditional single filtration structures on fine particles and colloids, effectively improving the purity of the recovered liquid, providing high-quality raw materials for subsequent resin regeneration or reuse, while improving resource utilization and reducing environmental pressure. The sealing cover 2 is equipped with two sets of feed ports at the top, which can realize the simultaneous feeding of waste liquid in a split manner, avoiding the accumulation of waste liquid above the filtration mechanism due to excessive flow at a single feed port, reducing the pressure on the local part of the filtration mechanism, and allowing the waste liquid to be more evenly distributed at the inlet of the multi-stage filtration mechanism 4, improving filtration efficiency and the balance of force on each layer of filter screen.

[0027] Specifically, the multi-stage filtration mechanism 4 includes an installation cylinder 41, a first filter screen 42, a second filter screen 43, and a third filter screen 44; the installation cylinder 41 is installed at the bottom of the sealing cover 2, and the first filter screen 42, the second filter screen 43, and the third filter screen 44 are installed inside the installation cylinder 41 from top to bottom.

[0028] With the installation cylinder 41, the first filter screen 42, the second filter screen 43, and the third filter screen 44, the installation cylinder 41 provides a unified installation carrier for the three sets of filter screens, making the filtration structure integrated and facilitating the connection or disassembly of the whole unit with the sealing cover 2, thus improving the convenience of device assembly and maintenance. The first filter screen 42, the second filter screen 43, and the third filter screen 44 are arranged sequentially from top to bottom, which can achieve the step-by-step interception of impurities in the waste liquid. The first filter screen 42 filters out larger particles first, the second filter screen 43 then processes medium-sized impurities, and finally the third filter screen 44 intercepts fine particles and some colloidal substances. The three-stage progressive filtration significantly improves the filtration accuracy, further enhances the purity of the recovered liquid, and meets the deep treatment requirements of resin regeneration waste liquid.

[0029] The bottom of the sealing cover 2 is fixedly installed with an installation ring 5 and a sealing ring 12, with the installation ring 5 located inside the sealing ring 12. The top of the installation cylinder 41 is fixedly installed on the outside of the installation ring 5 by multiple sets of bolts. The top of the recycling tank 1 is provided with a sealing groove 13 for the sealing ring 12 to be inserted.

[0030] With the installation ring 5, sealing ring 12, and sealing groove 13, the installation ring 5 at the bottom of the sealing cover 2 is fixedly connected to the installation cylinder 41 by multiple sets of bolts. This ensures the stability of the connection between the installation cylinder 41 and the sealing cover 2, preventing the installation cylinder 41 from shaking during filtration and affecting the filtration effect. It also facilitates the quick separation of the installation cylinder 41 and the sealing cover 2 by removing the bolts, making it easier to replace the multi-stage filtration mechanism 4 and improving operational convenience. The sealing ring 12 on the inner side of the installation ring 5 is inserted into the sealing groove 13 at the top of the recovery tank 1, which enhances the sealing between the sealing cover 2 and the recovery tank 1, preventing leakage during waste liquid treatment and avoiding waste liquid overflow that could lead to resource waste or environmental pollution.

[0031] Specifically, multiple sets of limiting posts 6 are fixedly installed at the bottom of the mounting cylinder 41, and multiple sets of limiting holes 7 are opened inside the support ring 3 for the limiting posts 6 to be inserted.

[0032] With the setting of the limiting post 6 and the limiting hole 7, the limiting post 6 at the bottom of the mounting cylinder 41 and the limiting hole 7 on the support ring 3 are inserted and cooperated, which can play a precise positioning role for the multi-stage filtration mechanism 4, avoid the mounting cylinder 41 from shifting due to the impact of waste liquid during the filtration process, further enhance the stability of the multi-stage filtration mechanism 4, ensure the stability of the filtration path, and improve filtration efficiency and effect.

[0033] In a further preferred embodiment, an adjustment mechanism 8 is also included to facilitate the raising and lowering of the sealing cap 2 and the multi-stage filtration mechanism 4, and the adjustment mechanism 8 is disposed on the outside of the recovery tank 1.

[0034] By adjusting the mechanism 8, the sealing cover 2 and the multi-stage filtration mechanism 4 can be raised and lowered, making it easy to put the multi-stage filtration mechanism 4 into the recovery tank 1 or remove it from the tank. This also makes it easy to quickly remove the multi-stage filtration mechanism 4 for cleaning and replacement after filtration, thus improving the ease of operation and practicality of the device.

[0035] Specifically, the adjustment mechanism 8 includes a fixed plate 81, two sets of support rods 82, a support plate 83, and an electric push rod 84. The fixed plate 81 is fixedly installed on the outside of the recycling tank 1. The two sets of support rods 82 are symmetrically fixedly installed on the top of the fixed plate 81, and the top of the two sets of support rods 82 is fixedly connected to the bottom of the support plate 83. The electric push rod 84 is fixedly installed on the top of the support plate 83, and the telescopic end of the electric push rod 84 passes through the support plate 83 and is fixedly connected to the top of the sealing cover 2.

[0036] With the setting of fixed plate 81, two sets of support rods 82, support plate 83 and electric push rod 84, fixed plate 81 and support rod 82 provide stable support for support plate 83. Electric push rod 84 can be LINAK-LA36 series. Electric push rod 84 as power source can drive the sealing cover 2 and multi-stage filtration mechanism 4 to rise and fall smoothly, realize automatic adjustment, replace manual operation, save labor costs, and ensure the stability of the lifting process.

[0037] The top of the sealing cover 2 is fixedly installed with multiple sets of guide rods 9 in a ring array, and all sets of guide rods 9 are slidably arranged inside the support plate 83.

[0038] With the guide rods 9 set, multiple sets of guide rods 9 in the ring array are slidably set in the support plate 83, which can play a guiding role in the lifting and lowering process of the sealing cover 2 and the multi-stage filtration mechanism 4, preventing deviation or tilting due to uneven force during lifting and lowering, ensuring the stability of the lifting and lowering process, and further improving the reliability of the adjustment mechanism 8.

[0039] Specifically, the top ends of multiple sets of guide rods 9 all pass through the support plate 83 and are fixedly installed with connecting plates 10, and the connecting plates 10 have through grooves 11 inside.

[0040] By setting the connecting plate 10 and the through groove 11, the connecting plate 10 can limit the sliding stroke of the guide rod 9, preventing the guide rod 9 from falling out of the support plate 83 during the lifting process, enhancing the stability of the connection between the guide rod 9 and the support plate 83, and ensuring the safety of the lifting process of the sealing cover 2 and the multi-stage filtration mechanism 4. The through groove 11 prevents the connecting plate 10 from colliding with the electric push rod 84 when it moves, ensuring the smooth operation of the adjustment mechanism 8.

[0041] Working principle: When using this utility model, the waste liquid is first injected into the recovery tank 1 through the feed port at the top of the sealing cover 2. Under the action of gravity, the waste liquid enters the multi-stage filtration mechanism 4, first flowing through the first filter screen 42, where larger particles of impurities are intercepted. The remaining waste liquid continues to flow downward through the second filter screen 43, where medium-sized particles are filtered. Finally, it is processed by the third filter screen 44, where fine particles and some colloidal substances are further intercepted. The purity of the recovered liquid is improved through three stages of filtration. The purified liquid after filtration enters the bottom of the recovery tank 1, where it can be collected and reused through the bottom drain port, thereby achieving efficient purification of the waste liquid.
