Description

Technical Field

[0001] This utility model relates to the field of fine filtration, specifically a multifunctional fine filter. Background Technology

[0002] In processing steps such as raw material recovery, raw material dissolution, and reduction refining, it is necessary to recover and treat various raw materials and the adhesive and contaminating residues generated after processing. Solid-liquid components are separated through operations such as recovery dissolution, reduction, filtration, and washing. Based on this, the solid or liquid containing the raw material components is collected, and the raw materials and residues adhering to the surface after filtration are then washed and recovered.

[0003] The above work requires switching between multiple devices, which causes material loss. Furthermore, multiple devices need to be cleaned after the work is completed, which brings inconvenience to users. Utility Model Content

[0004] To achieve the above objectives, this utility model provides a multifunctional fine filter that can solve the aforementioned problems. This utility model provides the following technical solution:

[0005] A multifunctional fine filter includes a support frame, an electrical control box, an outer tank, and a stirring system. The outer tank is mounted on the support frame, the electrical control box is mounted on the surface of the outer tank, and spray nozzles, filter cartridges, and filter plates are installed inside the outer tank. A top end cap is installed on the top of the outer tank, and a bottom end cap is installed on the bottom of the outer tank. The top end cap is provided with a feeding port, an observation port, a first spray port, a safety valve, an air inlet, a second spray port, a first voltage pressure gauge, a stirring motor, and a feed inlet. The stirring system is installed inside the outer tank and is connected to the stirring motor. A second voltage pressure gauge and a backwash pipe are installed outside the outer tank and are connected to the outer tank. The backwash pipe is connected to the filter pipe, and is equipped with... It has a backwash valve, a filter valve installed on the filter tube, a flushing interface, a filter plate tensioning motor, a drain port, a second flushing nozzle, a first flushing nozzle, a flushing coil, and a flushing port on the bottom end cap. The filter plate is connected to the filter plate tensioning system, and the filter plate tensioning motor is connected to the filter plate tensioning system. A second shut-off valve is installed on the second flushing nozzle, a first shut-off valve is installed on the first flushing nozzle, a coil shut-off valve is installed on the flushing coil, a drain valve is installed on the drain port, and a vent valve is installed on the outer tank. The electrical control box is electrically connected to the vent valve, drain valve, coil shut-off valve, first shut-off valve, second shut-off valve, filter plate tensioning motor, filter valve, backwash valve, stirring motor, and spray nozzle. The working process of this product is as follows: Interface docking: The air inlet is sealed and connected to the external air source system and pipeline respectively to ensure stable air pressure transmission; the feed inlet is connected to the external material conveying pipeline to ensure that the material can smoothly enter the device; the rinsing interface, the first spray port and the second spray port are respectively connected to the external clean water supply pipeline to provide water support for spraying and dissolving the agent and rinsing operations. All pipeline interfaces must be reinforced with matching seals. After connection, the interfaces must be checked to ensure they are secure to prevent leakage during operation. Connect the power cord of the stirring motor to the corresponding interface of the electrical control box. The backwash valve, filter valve and drain valve are respectively connected to the valve control module of the electrical control box through control lines to realize the valve start-stop and status control; the power line and control line of the filter plate tensioning motor are connected to the control unit of the electrical control box to ensure that the tightening and loosening of the filter plates are precise and controllable. Positive pressure filtration: Close all valves and tighten and fix the filter plates using the filter plate tensioning system to ensure a good seal between the filter plates. Then open the filter valve, and external materials enter the device through the inlet along the pipeline. Turn on the stirring system and observe the material status in real time through the observation port to ensure thorough stirring and uniform mixing. Open the air inlet and set the filtration air pressure to 0.3 MPa. Utilize positive pressure to accelerate the downward flow rate of the filtrate. The filtrate is filtered by the filter cylinder and filter plates. During filtration, the solution is discharged along the filter tube. When a certain amount of solution accumulates at the bottom, first open the drain valve and then close the filter valve to prevent the positive pressure from causing air stagnation. Then open the vent valve, and the solution passes through the filter plates again. The filtrate collects along the filter tube and the bottom end cap, and finally flows out from the drain port, ready for further processing. Under the filtration action of the filter cylinder and filter plates, solid-liquid separation is achieved, and impurities are trapped and adhere to the surface of the filter plates.During filtration, the safety pressure setting of the first voltage pressure gauge is 0.1 MPa. When the internal air pressure reaches the specified 0.1 MPa, the main air pipe is controlled to stop the air intake pressurization. To prevent excessive pressure inside the outer tank or filter plate blockage from damaging the device, a safety valve assists in pressure relief to ensure operational safety. Impurity dissolution and filter plate slag removal: Close the filter valve and drain valve, add the required dissolving agent through the feeding port, open the spray nozzles, and inject a measured amount of clean water. Use the solution to help loosen the impurities. After the agent is fully dissolved, reconnect the filtration operation. Activate the filter plate tensioning system; the filter plates automatically rise, and most of the impurities attached to the filter plates slide off under gravity. Open the first and second shut-off valves; clean water sprays from the first and second flushing nozzles to directionally flush the filter plate surface, ensuring that residual impurities are quickly detached and discharged. For the small amount of impurities attached to the inner wall of the bottom end cap, open the coil shut-off valve; clean water sprays along the flushing coil, washing off the impurities from the inner wall, which are then discharged from the drain port for subsequent processing. To ensure smooth drainage and prevent impurities from settling and accumulating, the flushing port needs to be opened regularly for rinsing and cleaning. Backwashing: To prevent impurities from settling and hardening, clogging the filter cartridge, regular backwashing is necessary. Set the backwash valve's electronic control switch to automatic mode. Clean water flows into the device along the backwash pipe, thoroughly soaking and rinsing the filter plates to completely remove any remaining fine impurities from the filter plate gaps, ensuring stable filtration performance. During cleaning, the safety pressure of the second voltage gauge is set to 0.1 MPa. When the air pressure inside the jacket reaches the specified 0.1 MPa, the backwash valve stops adding water. This prevents excessive pressure inside the jacket from damaging the filter plates. After cleaning, open the filter valve to drain the liquid from the jacket, achieving backwashing. Clean the filter plates, then close the filter valve, drain valve, and vent valve. Open the first and second shut-off valves, injecting clean water into the bottom end cap. After pressure is established, clean water permeates the filter plates, performing backwashing, with the water pressure maintained within 0.1 MPa. After completion, open the vent valve and drain valve and raise the filter plate to drain the injected clean water.

[0007] As a further embodiment of this invention, the sealing element is a sealing ring.

[0008] As a further embodiment of this utility model, a lighting device is also installed on the top end cap. The lighting device is electrically connected to the electrical control box to ensure normal operation even in dim lighting conditions.

[0009] As a further embodiment of this utility model: the top end cap is installed on the top of the outer barrel via a first flange, and the bottom end cap is installed on the bottom of the outer barrel via a second flange.

[0011] As a further embodiment of this invention, the bottom of the bracket is equipped with lifting casters, which can realize the conversion between the fixed state and the mobile state of the device, thereby improving the convenience and flexibility of use.

A second voltage pressure gauge 17 and a backwash pipe 18 are installed on the outside of the outer barrel 14 and are connected to the outer barrel 14. The backwash pipe 18 is connected to the filter pipe 20 and is equipped with a... A backwash valve 19 is provided. A filter valve 21 is installed on the filter tube 20. A flushing interface 23, a filter plate tensioning motor 27, a drain outlet 28, a second flushing nozzle 37, a first flushing nozzle 38, a flushing coil 39, and a flushing port 41 are provided on the bottom end cap 31. The filter plate 35 is connected to the filter plate tensioning system 36, and the filter plate tensioning motor 27 is connected to the filter plate tensioning system 36. A second shut-off valve 25 is provided on the second flushing nozzle 37. A first shut-off valve 22 is provided on the first flushing nozzle 38. A coil shut-off valve 24 is provided on the flushing coil 39. A drain valve 26 is provided on the drain outlet 28. A vent valve 42 is installed on the outer tank 14. The electrical control box 16 is electrically connected to the vent valve 42, the drain valve 26, the coil shut-off valve 24, the first shut-off valve 22, the second shut-off valve 25, the filter plate tensioning motor 27, the filter valve 21, the backwash valve 19, the stirring motor 9, and the spray nozzle 32. The working process of this product is as follows: Interface docking: Connect the air inlet 5 to the external air source system and pipeline in a sealed manner to ensure stable air pressure transmission; connect the feed inlet 10 to the external material conveying pipeline to ensure that the material can smoothly enter the device; connect the rinsing interface 23, the first spray port 3 and the second spray port 6 to the external clean water supply pipeline to provide water support for spraying and dissolving the agent and rinsing operations. All pipeline interfaces must be reinforced with compatible seals. After connection, check whether the interface is firm to prevent leakage during operation. Connect the power line of the stirring motor 9 to the corresponding interface of the electrical control box 16. Connect the backwash valve 19, filter valve 21 and drain valve 26 to the valve control module of the electrical control box 16 through control lines to realize the valve start and stop and status control; connect the power line and control line of the filter plate tensioning motor 27 to the control unit of the electrical control box 16 to ensure that the tightening and loosening action of the filter plate 35 is precise and controllable.Positive pressure filtration: Close all valves and tighten and fix the filter plates 35 through the filter plate tightening system 36 to ensure good sealing between the filter plates 35; then open the filter valve 21, and the external material enters the device from the feed port 10 along the pipeline. Turn on the stirring system 33 and observe the material status in real time through the observation port 2 to ensure sufficient stirring and uniform mixing; open the air inlet 5 and set the filtration air pressure to 0.3MPa. Use positive air pressure to accelerate the downward flow speed of the filtrate. The filtrate is filtered by the filter cylinder 34 and the filter plate 35. During filtration, the solution is discharged along the filter tube 20. When a certain amount of solution is collected at the bottom, first open the drain valve 26 and then close the filter valve 21 to prevent the positive air pressure from holding back the air. Then open the vent valve 42, and the solution is filtered again through the filter plate 35. The filtrate is collected along the filter tube 20 and the bottom end cap 31 and finally flows out from the drain port 28, ready for the next step of processing; under the filtration action of the filter cylinder 34 and the filter plate 35, solid-liquid separation is achieved, and impurities are intercepted and adhered to the surface of the filter plate 35. During filtration, the safety pressure setting of the first voltage pressure gauge 8 is 0.1 MPa. When the air pressure inside the device reaches the specified 0.1 MPa, the main air pipe is controlled to stop the air intake and pressurization. To prevent excessive pressure inside the outer tank 14 or blockage of the filter plate 35 that could damage the device, the safety valve 4 assists in pressure relief to ensure operational safety. For impurity dissolution and filter plate 35 slag discharge: Close the filter valve 21 and the drain valve 26, add the required dissolving agent through the feed port 1, open the spray nozzle 32, and inject a measured amount of clean water. Use the solution to help loosen the impurities. After the agent is fully dissolved, reconnect the filtration operation. Activate the filter plate tensioning system 36; the filter plate 35 automatically rises, and most of the impurities adhering to the filter plate 35 slide off under gravity. Open the first shut-off valve 22 and the second shut-off valve 25, and clean water sprays out from the first flushing nozzle 38 and the second flushing nozzle 37 to directionally flush the surface of the filter plate 35, ensuring that residual impurities are quickly detached and discharged. For a small amount of impurities adhering to the inner wall of the bottom end cap 31, open the coil shut-off valve 24, and clean water sprays out along the flushing coil 39 to wash off the impurities on the inner wall, which are then discharged from the drain port 28 for subsequent processing. To ensure that the drain port 28 is unobstructed and to avoid the sedimentation and accumulation of impurities, the flushing port 41 needs to be opened regularly for flushing and cleaning. Backwashing: To prevent impurities from settling and hardening and clogging the filter cartridge 34, backwashing needs to be performed regularly. Set the backwash valve 19 to automatic mode, and clean water flows into the device along the backwash pipe 18 to fully soak and flush the filter plate 35, thoroughly removing the small impurities remaining in the gaps of the filter plate 35 and ensuring the stable filtration performance of the filter plate 35. During cleaning, the safety pressure setting of the second voltage pressure gauge 17 is 0.1 MPa. When the air pressure inside the jacket reaches the specified 0.1 MPa, the backwash valve 19 stops adding water to prevent excessive pressure inside the jacket from damaging the filter plate 35. After cleaning, the filter valve 21 is opened to drain the liquid inside the jacket, achieving backwashing of the jacket; the filter plate 35 is cleaned, and the filter valve 21, drain valve 26, and vent valve 42 are closed. The first shut-off valve 22 and the second shut-off valve 25 are opened to inject clean water into the bottom end cap 31.After pressure is established, clean water permeates the filter plate 35 for backwashing, with the water pressure within 0.1 MPa. After completion, the vent valve 42 and drain valve 26 are opened, and the filter plate 35 is raised to drain the injected clean water.
