Description

Technical Field

[0001] This utility model relates to the field of resin sieving technology, specifically to a chelating resin sieving device with airflow assistance. Background Technology

[0002] Chelating resins are a class of cross-linked functional polymers that can form multi-coordinate complexes with metal ions. The adsorption mechanism of chelating resins for metal ions is that the functional atoms on the resin undergo coordination reactions with the metal ions to form a stable structure similar to small molecule chelates. In contrast, the adsorption mechanism of ion exchange resins is electrostatic interaction. Therefore, compared with ion exchange resins, chelating resins have a stronger binding force with metal ions and higher selectivity. They can be widely used in the recovery and separation of various metal ions, the resolution of amino acids, as well as in hydrometallurgy and pollution control. When chelating resin particles are screened, screening equipment is required. The screened chelating resin particles are then used for subsequent production processing and use.

[0003] For example, Chinese Patent CN218963301U discloses a screening machine for chelating resin production. This utility model includes a mounting base plate and a support base. The support base is fixedly installed on the top of the mounting base plate, and a mounting top plate is fixedly installed on the top of the support base. A connecting rod is fixedly installed on the bottom of the mounting top plate, and a fixing ring is fixedly installed on the bottom of the connecting rod. A screen barrel is rotatably installed on the inner side wall of the fixing ring. The screen barrel is provided with screen holes, and a collection cover is provided at the bottom of the screen barrel. A screen mesh is fixedly installed on the inner side wall of the bottom of the collection cover. A support and reset assembly is provided on one side of the collection cover, and a drive assembly is provided on one side of the support base. The support and reset assembly includes a support plate, a horizontal plate, a reset spring, a side plate, and a limiting rod. The support plate is fixedly installed on the top of the mounting base plate. The chelating resin particles can be screened in the first stage through the screen barrel, and then the chelating resin particles can be screened in the second stage through the screen mesh. The screening effect is good and it is easy to use.

[0004] However, the existing screening machines used for chelating resin production are extremely inconvenient to disassemble and clean during use. Once the screen becomes clogged, the screening efficiency will drop significantly. Moreover, if the screen is not cleaned in time, the clogging problem will become more and more serious, which will not only affect product quality but may also cause equipment failure and bring many adverse effects to production. Therefore, there is still room for further improvement.

[0005] Therefore, we propose a chelating resin screening device with airflow assistance to solve the problems mentioned above. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Please see Figures 1-5 This utility model provides a technical solution: a chelating resin screening device with airflow assistance, comprising: a base 1, a collection frame 2, a mounting frame 3, a limiting ring 4, a connecting ring 5, a connecting groove 6, a connecting frame 7, a sealing cover 8, a rectangular rod 9, a rectangular groove 10, a screening cylinder 11, a servo motor 12, an air pump 13, an air supply pipe 14, an air jet pipe 15, an air jet head 16, and a connecting rod 17.

[0019] In existing screening machines used for chelating resin production, disassembling and cleaning the screen barrel is extremely inconvenient. Once the screen barrel becomes clogged, the screening efficiency drops significantly. Moreover, if the screen barrel is not cleaned in time, the clogging problem will worsen, affecting product quality and potentially causing equipment malfunctions, thus creating numerous adverse effects on production. Therefore, there is room for further improvement.

[0020] When using a chelating resin screening device with airflow assistance, such as Figure 1 , Figure 2 and Figure 5 As shown, before performing the chelating resin screening operation, the screening cylinder 11 is first installed and fixed. The screening cylinder 11 is placed inside the connecting frame 7, aligning the rectangular groove 10 on the outside of the screening cylinder 11 with the rectangular rod 9 fixed on the connecting frame 7. The screening cylinder 11 is pushed until the rectangular rod 9 is fully engaged in the rectangular groove 10, thus fixing the screening cylinder 11 to the connecting frame 7. Then, the sealing cover 8 is rotated; the sealing cover 8 and the connecting frame 7 are connected by a hinge, so that the sealing cover 8 fits against the lower opening of the screening cylinder 11. Finally, the sealing bolts are used to fix the sealing cover 8 to the connecting frame 7, completing the installation and sealing of the screening cylinder 11 to prevent resin particles from leaking from the lower end during the screening process.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the loading operation is performed: Open the sealing cover 8 to see the opening on the right side of the screening cylinder 11, pour the chelated resin particles to be screened into the screening cylinder 11, and control the feed rate to avoid overloading the screening cylinder 11; after loading, close the sealing cover 8 to prevent resin particles from splashing during the screening process.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the starting device performs the screening operation: the servo motor 12 and the air pump 13 are started simultaneously. The servo motor 12 is powered on and its output shaft drives the connecting frame 7 to rotate. The left side of the connecting frame 7 is fixedly connected to the output shaft of the servo motor 12. The connecting ring 5 on the outer side of the connecting frame 7 slides along the connecting groove 6 on the inner side of the limiting ring 4. The connecting ring 5 is engaged with the connecting groove 6. The limiting ring 4 is fixed on the lower side of the mounting frame 3, providing a limit and support for the rotation of the connecting frame 7 and preventing the connecting frame 7 from rotating off-center. The connecting frame 7 drives the screening cylinder 11 to rotate synchronously. The chelated resin particles in the screening cylinder 11 move towards the cylinder wall under the action of centrifugal force. The resin particles that meet the particle size requirements fall into the collection frame 2 below through the sieve holes of the screening cylinder 11. The collection frame 2 is set on the upper side of the base 1 and located directly below the screening cylinder 11 to realize the screening of resin particles.

[0023] At the same time, the air pump 13 is powered on to generate a high-speed airflow, which is delivered to the jet pipe 15 through the air supply pipe 14. The air pump 13 is fixedly connected to one end of the air supply pipe 14, and the other end of the air supply pipe 14 is fixedly connected to the jet pipe 15. The air supply pipe 14 is symmetrical about the vertical central axis of the mounting frame 3. The jet pipe 15 is fixed to the lower side of the mounting frame 3 through the connecting rod 17. In addition, the jet pipe 15 is fixedly connected to the connecting rod 17, and the connecting rod 17 is fixedly connected to the mounting frame 3. The jet heads 16 arranged in an array on the side of the jet pipe 15 spray air towards the screen holes of the screening cylinder 11. The airflow can blow away the resin particles adhering to the screen holes in time, avoid screen blockage, and ensure that the screening process continues to be efficient.

[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, after screening and cleaning / maintenance, turn off the servo motor 12 and air pump 13. After the screening cylinder 11 has completely stopped rotating, remove the collection frame 2 from the top of the base 1 and pour out the collected screened resin particles to complete the material collection. If the screening cylinder 11 needs to be cleaned or replaced, rotate the sealing cover 8 in the opposite direction to open it, and then pull the screening cylinder 11 away from the rectangular rod 9 to separate the rectangular rod 9 from the rectangular groove 10. The screening cylinder 11 can then be removed from the connecting frame 7. Clean the screening cylinder 11 or replace it with a new one. After cleaning or replacement, reinstall the screening cylinder 11 according to the above installation steps for future use.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
