Description

Technical Field

[0001] This utility model belongs to the field of security filter cleaning technology, specifically relating to a filter element cleaning device that combines a high-pressure nozzle with ultrasonic waves. Background Technology

[0002] Security filter cartridges trap a large amount of impurities during use, leading to increased pressure differential and decreased flow rate, requiring regular cleaning. In traditional industrial systems, security filter cartridges are often used as disposable consumables, occasionally reused after manual hydraulic cleaning during routine use.

[0003] Currently, manual hydraulic cleaning is costly, but the cleaning effect is limited. The inner wall and folds of the filter element are not thoroughly cleaned, and the quality of each cleaning is inconsistent, which cannot guarantee the effect of use. Moreover, it relies on manual operation, which requires high technical skills from the operators, resulting in high costs and poor economic efficiency. Utility Model Content

[0004] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing a filter element cleaning device that combines a high-pressure nozzle with ultrasonic waves. This invention offers high cleaning efficiency, excellent results, and effectively removes stubborn dirt while reducing the risk of filter element damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] This utility model provides a filter element cleaning device combining high-pressure nozzles and ultrasonic waves, including a cleaning tank. The cleaning tank has a rotating base located in the lower center, which connects to the filter element and rotates within the tank around its central axis. A stepper motor is connected to the rotating base to drive its rotation. The cleaning tank has an inlet and an outlet at its lower part. An inlet pipe is connected to the inlet, extending into the tank and connecting to multiple fan-shaped filter element nozzles. An outlet pipe is connected to the outlet. Multiple ultrasonic generators are connected to the inner wall of the cleaning tank. A top cover is detachably connected to the top of the cleaning tank.

[0007] Furthermore, the inlet pipe branches into two paths within the cleaning tank. The first inlet pipe runs along the inner wall of the cleaning tank and has multiple fan-shaped external nozzles evenly distributed from top to bottom. The rotating base is hollow at its central axis. The second inlet pipe passes through the hollow of the rotating base and extends into the interior of the filter element. A gap is left between the second inlet pipe and the rotating base, and multiple fan-shaped internal nozzles are evenly distributed from top to bottom on the second inlet pipe. The rotating base can rotate around the fixed second inlet pipe as its central axis.

[0008] Furthermore, a limiting fixing seat is provided at the center of the bottom side of the upper cover corresponding to the position of the filter element. After the filter element is installed on the rotating base, its top is restricted within the limiting fixing seat, and the filter element can rotate within the limiting fixing seat.

[0009] Furthermore, the inlet pipe branches outside the cleaning tank and connects to the clear water tank and the chemical tank respectively. A water injection control system is installed on the branch pipe connected to the clear water tank, and a chemical injection control system is installed on the branch pipe connected to the chemical tank.

[0010] Furthermore, a liquid level sensor is provided on the bottom side of the upper cover. The liquid level sensor is electrically connected to the distribution control system outside the cleaning tank. The distribution control system is electrically connected to the water injection control system and the chemical injection control system.

[0011] Furthermore, an observation window is provided on the side of the cleaning tank.

[0012] The beneficial effects of this utility model.

[0013] This invention utilizes a fan-shaped filter nozzle to cover the inner and outer surfaces and the entire height of the filter element, achieving rotating water cleaning and ensuring a more comprehensive and thorough cleaning. During chemical soaking, ultrasonic-assisted washing effectively loosens and decomposes sticky dirt, colloids, and organic matter that are difficult to remove with water rinsing. The physical scouring of the moving water flow and the cavitation stripping of the ultrasonic waves create a powerful synergistic effect, resulting in a more thorough cleaning. It boasts high cleaning efficiency, an automated cleaning process, and multiple methods working together to significantly shorten cleaning time and reduce manual intervention. Compared to simple high-pressure manual rinsing, it reduces the risk of damage to the filter element structure caused by direct impact from high-pressure water flow. Attached Figure Description

Detailed Implementation

[0017] As shown in the accompanying drawings, this embodiment provides a filter cleaning device combining a high-pressure nozzle and ultrasonic waves. It includes a cleaning tank 1, with a rotating base 2 located in the lower center of the tank 1. The rotating base 2 is used to connect a filter element 3 and can rotate around its own central axis within the cleaning tank 1. A stepper motor 4 is connected to the rotating base 2 to drive its rotation. The filter element 3 is installed on the rotating base 2, and the stepper motor 4 drives the rotating base 2 to rotate, which in turn drives the filter element 3 to rotate.

[0018] The cleaning tank 1 has an inlet and an outlet at its bottom. An inlet pipe 5 is connected to the inlet, extending into the cleaning tank 1 and branching into two paths. The first inlet pipe 5 runs along the inner wall of the cleaning tank 1, and multiple fan-shaped external nozzles 9 are evenly distributed from top to bottom on the first inlet pipe 5. These fan-shaped external nozzles 9 are used to evenly spray the liquid onto the outside of the filter element 3. The rotating base 2 is hollow at its central axis. The second inlet pipe 5 passes through the hollow part of the rotating base 2 and extends into the interior of the filter element 3. A gap is left between the second inlet pipe 5 and the rotating base 2, and multiple fan-shaped internal nozzles 10 are evenly distributed from top to bottom on the second inlet pipe 5. These fan-shaped internal nozzles 10 are used to evenly spray the liquid into the interior of the filter element 3.

[0019] The rotating base 2 drives the filter element 3 to rotate around the fixed second liquid inlet pipe 5 as the central axis, and cleans the inside and outside of the rotating filter element 3 simultaneously through the fan-shaped external nozzle 9 and the fan-shaped internal nozzle 10, ensuring a more comprehensive cleaning of the filter element 3.

[0020] A top cover 8 is detachably connected to the top of the cleaning tank 1. A limiting fixing seat 11 is provided at the bottom center of the top cover 8 corresponding to the position of the filter element 3. After the filter element 3 is installed on the rotating base 2, its top is restricted within the limiting fixing seat 11, and the filter element 3 can rotate within the limiting fixing seat 11.

[0021] Multiple ultrasonic generators 7 are connected to the inner wall of the cleaning tank 1. During the immersion stage, the ultrasonic waves generated by the ultrasonic generators 7 are used for deep cleaning, with the aim of cleaning the stubborn impurities deep inside the filter element 3.

[0022] The inlet pipe 5 branches outside the cleaning tank 1 and connects to the clean water tank 12 and the chemical tank 13 respectively. A water injection control system 14 is installed on the branch pipe of the inlet pipe 5 connected to the clean water tank 12, and a chemical injection control system 15 is installed on the branch pipe of the inlet pipe 5 connected to the chemical tank 13. A liquid level sensor 16 is installed on the bottom side of the top cover 8. The liquid level sensor 16 is electrically connected to the distributed control system 17 outside the cleaning tank 1. The distributed control system 17 is electrically connected to the water injection control system 14 and the chemical injection control system 15. The liquid level sensor 16 senses the liquid level information in the cleaning tank 1 and transmits it to the distributed control system 17. The distributed control system 17 then controls the water injection control system 14 to supply clean water from the clean water tank 12 into the cleaning tank 1 through the inlet pipe 5. The distributed control system 17 also controls the chemical injection control system 15 to supply chemical from the chemical tank 13 into the cleaning tank 1 through the inlet pipe 5.

[0023] The drain outlet is connected to a drain pipe 6, which is used to discharge wastewater, residual cleaning agent and impurities that fall off during the ultrasonic cleaning process to the external drain pool 19.

[0024] An observation window 18 is provided on the side of the cleaning tank 1, through which the condition of the filter element 3 can be observed and the cleaning effect can be evaluated.

[0025] The entire cleaning process can be roughly summarized as: preparation - setting parameters - pre-cleaning - soaking - rinsing - end. The specific cleaning process is as follows:

[0026] 1. Preparation: Place the filter element 3 to be cleaned into the cleaning tank 1 and install the bottom on the rotating base 2. Close the top cover 8 of the cleaning tank 1 and insert the upper part of the filter element 3 into the limiting and fixing seat 11. Then connect and fix the top cover 8 to the cleaning tank 1.

[0027] 2. Setting parameters: Assess the severity and type of dirt on filter element 3, set the cleaning time and prepare the cleaning solution.

[0028] 3. Pre-cleaning: Turn on the stepper motor 4 to make the filter element 3 rotate. Clean water enters through the inlet pipe 5 and is rinsed by the fan-shaped internal nozzle 10 and the fan-shaped external nozzle 9 to remove larger impurities on the surface of the filter element 3. The wastewater generated is discharged to the drain pool 19 through the drain pipe 6.

[0029] 4. Immersion: The cleaning agent enters through the inlet pipe 5 and rinses the rotating filter element 3 through the fan-shaped internal nozzle 10 and the fan-shaped external nozzle 9. The cleaning tank 1 is filled with cleaning agent. The liquid level sensor 16 transmits the liquid level information to the distributed control system 17. The filling stops when the target liquid level is reached. The cleaning agent soaks the filter element and performs deep cleaning with the ultrasonic waves generated by the ultrasonic generator 7. After the cleaning is completed, the cleaning agent is discharged to the drain pool 19 through the drain pipe 6.

[0030] 5. Rinsing: Clean water enters through the inlet pipe 5 and rinses the rotating filter element 3 through the fan-shaped internal nozzle 10 and the fan-shaped external nozzle 9 to remove residual cleaning agent and impurities that fall off during the ultrasonic cleaning process. After the process is completed, the wastewater and waste are discharged to the drainage pool 19 through the drain pipe 6.

[0031] 6. End: Observe the filter element 3 through the side window to evaluate the cleaning effect. After the cleaning effect meets the standard, open the top cover 8 and take out the filter element 3. The cleaning is complete.
