Description

Technical Field

[0001] This utility model relates to the field of resin traps in the coal chemical industry, and in particular to a resin trap. Background Technology

[0002] In coal chemical production, resins are widely used in water treatment, syngas purification, and chemical refining to remove ionic impurities or adsorb harmful gases from water. However, resins are prone to breakage during use due to mechanical friction, chemical corrosion, or thermal stress, forming fine particles. If these fine resin particles enter downstream systems with the fluid, they can cause problems such as equipment blockage, wear, or catalyst contamination.

[0003] To address this issue, a resin trap, as a key protective device, is installed at the outlet of the ion exchange system to intercept escaping resin particles, thereby ensuring the stable operation of the process system.

[0004] Currently, most resin traps on the market use a fixed filter structure, which works by mechanically blocking resin particles. However, this structure has significant drawbacks.

[0005] First, when the filter screen surface is clogged with resin or impurities, the system pressure differential will increase significantly. At this point, the machine must be shut down and the filter screen removed for manual cleaning. This maintenance method is not only complicated in operation, but it also leads to production interruption.

[0006] Secondly, due to the complex composition of coal chemical media, which contains sticky impurities such as tar and dust, these substances easily adhere to the filter screen surface, forming stubborn dirt. Even more seriously, tiny resin particles often embed themselves in the filter screen pores, causing deep blockages that are difficult to remove.

[0007] This frequent clogging problem has brought many adverse effects: on the one hand, the filter screen needs to be replaced or cleaned frequently, greatly increasing maintenance costs; on the other hand, coal chemical production has strict continuous requirements, and frequent downtime for maintenance will significantly affect production efficiency and cause serious economic losses. The existing resin trap structure clearly cannot meet the coal chemical industry's demand for long-term stable operation of equipment. Utility Model Content

[0008] To address the problem of difficult cleaning of existing resin traps after the filter screen becomes clogged, this invention proposes a resin trap that, when the filter screen becomes clogged, switches to an air-water backwash mode. The aeration device effectively peels off and removes resin particles and impurities attached to the screen surface, as well as any remaining water inside the trap. The aeration device drives the internal water to be strongly agitated, causing the resin and water to mix thoroughly and suspend. Subsequently, the drain valve is opened to discharge the wastewater.

[0009] The technical solution adopted by this utility model to solve its technical problem is:

[0010] A resin trap includes an aeration device, which includes an aeration pipe and a diffusion device. The diffusion device includes a diffusion device body and aeration blades. The inlet end of the aeration pipe is connected to an external air source through a compressed air valve, and the outlet end of the aeration pipe is fixedly connected to the air inlet of the diffusion device body. The aeration blades are vertically fixedly connected to the diffusion device body.

[0011] It also includes a trap, the trap's outer shell is equipped with an inlet, a product outlet and a drain outlet, the trap's outer shell is equipped with a filter screen, the trap's outer shell is divided into an inlet chamber and a product chamber by the filter screen, the inlet is connected to the inlet chamber through an inlet valve, the product outlet is connected to the product chamber through a product valve, and the drain outlet is equipped with a drain valve.

[0012] In a further technical solution, the aeration pipe and the product water output pipe where the product water valve is located are set in the same pipeline.

[0013] In a further technical solution, the filter screen has a cylindrical mesh structure.

[0014] In a further technical solution, the diffuser body is cylindrical, and the air inlet of the diffuser body is located at the geometric center of the diffuser body.

[0015] A further technical solution involves aeration blades evenly distributed around the edge of the diffuser body, perpendicular to the central edge of the body.

[0016] In a further technical solution, the central axis of the diffusion device body is arranged coaxially with the cylindrical axis of the filter screen.

[0017] In a further technical solution, the aeration device is installed on one side of the filter screen's water production tank.

[0018] In a further technical solution, the surface of the aeration blades is uniformly distributed with air pores.

[0019] In a further technical solution, the aeration blades maintain a radial distance of 10-30mm from the inner surface of the filter screen.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This invention achieves air-water backwashing of the resin trap by introducing an aeration device. When the filter screen becomes clogged, the system can switch to backwashing mode, using compressed air and internal water to create strong agitation, effectively peeling off and removing resin particles and impurities adhering to the screen surface. This design avoids the cumbersome operation of disassembling and cleaning traditional fixed filter screens, significantly improving cleaning efficiency while reducing manual intervention and maintenance costs.

[0022] Because it eliminates the need for frequent downtime for cleaning, this invention significantly reduces production interruption time, meeting the coal chemical industry's demand for long-term stable equipment operation. This not only improves production efficiency but also reduces economic losses caused by downtime for maintenance, bringing significant economic benefits to enterprises. Attached Figure Description

[0028] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments of the present invention. The terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0030] The embodiments of this application are for achieving the above objectives, such as... Figure 1As shown, this utility model provides a resin trap, including an aeration device, which includes an aeration pipe 3 and a diffusion device 8. The diffusion device includes a diffusion device body 9 and aeration blades 10. The inlet end 14 of the aeration pipe is connected to an external air source through a compressed air valve 2. The outlet end 15 of the aeration pipe is fixedly connected to the air inlet 16 of the diffusion device body. The aeration blades 10 are vertically fixedly connected to the diffusion device body 9.

[0031] Aeration pipe 3 is a compressed air delivery channel used to introduce compressed air supplied by an external air source into the resin trap.

[0032] In backwash mode, when the filter screen is clogged, the compressed air valve opens, and compressed air enters the diffuser through the aeration pipe, providing a high-pressure airflow to drive the air-water backwash process, causing the resin particles attached to the filter screen to loosen and peel off.

[0033] The air inlet of the diffuser body 9 receives compressed air from the aeration pipe 3 and distributes it evenly to the entire filter screen through the aeration blades 10. By optimizing the airflow distribution, the compressed air impacts the filter screen at the best angle, thereby improving the resin stripping efficiency.

[0034] The aeration blades have evenly distributed pores on their surface, which cut the concentrated compressed air into tiny bubbles, improving the air washing effect.

[0035] This utility model provides a resin trap, which also includes a trap. The trap housing 6 is provided with an inlet 11, a product water outlet 12 and a drain outlet 13. A filter screen 5 is provided inside the trap housing. The trap housing 6 is divided into an inlet water chamber 17 and a product water chamber 18 by the filter screen 5. The inlet water outlet is connected to the inlet water chamber through an inlet water valve 1, and the product water outlet 12 is connected to the product water chamber through a product water valve 4. A drain valve 7 is provided at the drain outlet, and an aeration device 3 is provided on one side of the product water chamber of the filter screen.

[0036] The function of a filter is to intercept escaping resin particles and prevent them from entering downstream equipment. It primarily uses filter screens or cartridges to capture resin particles, preventing them from entering pipes, valves, and other downstream devices, thus preventing blockages and wear, extending equipment lifespan, and reducing maintenance costs.

[0037] In this embodiment, as Figure 2 As shown, the aeration device includes an aeration pipe 3 and a diffusion device 8. The aeration pipe 3 and the product water pipeline are arranged in an integrated structure. The aeration pipe 3 is connected to an external air source through a compressed air valve 2. The aeration pipe 3 is not set up independently, but is integrated with the product water output pipeline where the product water valve 4 is located.

[0038] This design integrates the gas delivery path and the liquid production path into one physical structure by sharing a pipeline channel, which simplifies the system architecture and optimizes the efficiency of media transmission.

[0039] In this embodiment, the diffusion device 8 includes a diffusion device body 9 and an aeration blade 10. The diffusion device body is circular, and the air inlet 16 of the diffusion device body is located at the geometric center of the diffusion device body. It is a circular through hole with a diameter that matches the inner diameter of the aeration pipe outlet. The material is sturdy and has good corrosion resistance, and can adapt to complex working environments.

[0040] The aeration blades 10 are evenly distributed around the edge of the diffuser body and are fixedly connected to the center edge of the diffuser body.

[0041] In this embodiment, the structural design of the diffusion device achieves multiple significant technical effects through the optimized combination of central air intake and radially distributed aeration blades.

[0042] The central air intake circular through-hole design and precise matching with the aeration pipe outlet, combined with the radially evenly distributed vertical aeration blades, form a highly uniform radial airflow distribution pattern, ensuring that the entire inner surface of the filter screen is subjected to consistent and sufficient airflow impact.

[0043] This structure not only makes the airflow distribution more balanced, avoiding the problem of uneven airflow distribution common in traditional designs, but also uses vertically arranged blades to make the airflow impact the filter surface at the optimal angle, generating a strong turbulence effect and shear force, which significantly improves the resin peeling efficiency.

[0044] Secondly, this integrated and robust structural design has excellent mechanical properties. The central air intake effectively reduces the radial impact of airflow on the device, and the evenly distributed blades ensure balanced stress on the device. In addition, the use of high-strength and corrosion-resistant materials ensures long-term stable operation of the device under high-pressure airflow conditions.

[0045] In this embodiment, the surface of the aeration blade 10 is uniformly distributed with air holes, and the design of the air hole diameter can ensure that compressed air is released uniformly at a suitable flow rate and volume.

[0046] When compressed air enters the diffuser 8 from the aeration pipe 3, it will converge in the diffuser body and then be evenly dispersed to the surrounding area through the air holes on the aeration blades 10.

[0047] During operation, the aeration blades play a crucial role in dispersing and cutting the airflow. On one hand, they guide the compressed air gathered from the base plate evenly to the surroundings, allowing the airflow to diffuse over a wider area and increasing the aeration coverage. On the other hand, the blades cut the airflow, breaking the originally concentrated airflow into numerous tiny airflow streams, further refining the generation of bubbles and making the released bubbles smaller and more uniform. This significantly improves the aeration effect and enhances the efficiency of flushing and removing impurities from the resin trap during the air washing process.

[0048] In this embodiment, as Figure 3 As shown, filter 5 has a cylindrical structure and is woven from metal wire or high-strength synthetic fiber. Its mesh structure is regular and the mesh size is uniform, which can accurately intercept impurities such as resin particles.

[0049] In this embodiment, the central axis of the circular base plate of the diffusion device 8 is strictly coaxial with the cylindrical axis of the filter screen 5, and the aeration blades and the inner surface of the filter screen 5 maintain a radial distance of 10mm-30mm to form an annular airflow channel.

[0050] The central axis of the circular base of the diffuser 8 is strictly coaxial with the cylindrical axis of the filter screen 5, ensuring that the airflow forms a uniformly distributed annular airflow channel on the inner surface of the filter screen. This precise symmetrical structure allows compressed air to diffuse evenly along the axial direction of the filter screen after passing through the aeration blades, avoiding the uneven airflow distribution problem common in traditional eccentric designs.

[0051] Meanwhile, the optimized radial spacing design of 10-30mm ensures that the airflow maintains sufficient impact speed when it reaches the filter surface, while avoiding airflow obstruction caused by too small a spacing, thus achieving the best resin particle peeling efficiency.

[0052] The principle of this utility model during installation and use is as follows:

[0053] When the resin trap is functioning normally, open the inlet valve 1 and the product water valve 4. Water flows through the inlet into the trap housing 6 and is filtered by the filter screen 5. The filtered water flows out through the pipeline containing the product water valve 4 and is collected and reused as product water. At this time, the compressed air valve 2 and the drain valve are closed, and no compressed air enters. During this process, the filter screen 5 plays an interception role, blocking resin and other impurities on its outside, thus achieving normal filtration and product water function.

[0054] When backwashing of the resin trap is required, close the inlet valve 1 and the product water valve 4 to cut off the system's inlet and outlet water. Then open the compressed air valve 2. At this time, there is still water in the trap. Compressed air is quickly delivered to the diffuser 8 through the aeration pipe 3 via the compressed air valve 2 at a certain pressure. After entering the trap, the compressed air forms a high-speed airflow through the evenly distributed air holes on the diffuser 8. The airflow impacts the surface of the filter screen 5. Utilizing the turbulence effect and shear force of the gas, it drives the internal water to be strongly agitated, causing the resin particles and impurities attached to the filter screen to be fully loosened and peeled off.

[0055] The suspended resin and wastewater form a mixed fluid under the propulsion of airflow, which peels off from the surface of the trap and moves with the water flow. After rinsing, the drain valve is opened to discharge the wastewater, completing the air-water backwashing process.

[0056] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
